Rain clouds darkened the sky outside, smothering the sun with endless billows of dark, cottony gloom. After the searing summer months, it was a welcome reprieve for most residents of the Sunshine State, but not for Kai.

The young leopard missed the scorching sun, and bitterly resented being denied the chance to practice for the upcoming Junior Surfers Challenge; for a boy of eleven years (almost twelve!) such as him, there was no more prestigious an event in the surfing world that didn't involve flying out somewhere. Instead of preparing for the tough competition, the boy was slouched at his computer chair in naught but his colorful boardshorts, browsing VidTube and feeling the full brunt of seasonal affective disorder. Spring was decidedly wet this year, and he did not approve. His choice of wardrobe was very much a deliberate protest.

Luckily, he had entertainment. Recently, he had found himself enamoured with a VidTuber boy - a cheetah about his own age, and a fellow watersports enthusiast - and he had been watching every upload from the perpetually shirtless (a trait they had in common) vlogger, paying special attention to those videos of the young internet celebrity visiting the beach or water-parks.

If he was being honest with himself, it wasn't just a shared interest in all things wet and wild that compelled Kai to watch the hammy VidTuber's online antics, nor was it purely an attempt to vicariously experience those sunny days again. Though he was trying not to think too much about that: if he thought too much about why he liked watching those "ice bath challenge" videos, he might stumble upon an awkward answer, one that recalled playground slurs he himself was guilty of hurling at others.

There was a knock on the door, interrupting his solemn contemplation of the cheetah boy's shoulderblades as viewed by a Pro-Go camera mounted to the back of his waterslide tube, and he immediately minimised the video. A reflexive action ever since he'd started visiting those "other" video sites.

Yes, Kai was very grateful his parents hadn't opted for an internet filter.

"Yeah?" he called.

His mom's gentle lilt was muffled by the door. "Hey hon, your sister will be here soon, she says she's going to take you out somewhere."

"Okay, mom. Tell me when she's here?" A brief surge of excitement coursed through his body, but he maintained his cool.

"Sure will."

His mom closed the door, and Kai reclined in his cheap computer chair and stared at his monitor, thinking. After a moment, he brought his browser up again and continued watching the video of somebody else having fun. Twiddling his shark-tooth necklace, scratching his bare chest with it thoughtfully. Even on a rainy day, he saw little need for t-shirts.

It had been awhile since his sister had visited from the university, visiting just once since moving to student accommodation two months ago. She moved away only a week after she had taken Kai to the university for that experiment that had almost cost the precocious boy his sanity. Some nonsense about finding a part-time job and wanting to make it on her own. Kai had only just started feeling up to forgiving her for it.

Their parents still had no idea how their son had risked his sanity to help their daughter's academic career. Now she needed his help again. They'd worked it out already through text messages during the week.

Memories of that day came rushing back all of a sudden, and Kai's heart fluttered. Remembering how he had been at the total mercy of a dispassionate machine that tore intense feelings from him, over and over, and he couldn't do anything to even delay it. The memories knotted his stomach, and he felt a twinge in his boxer-briefs. And another, when he realized he was very probably going to be put through that ordeal again. Today.

Oh wow. It was today!

Instinctively, he fingered his shorts' waistband, stopping himself when he realized what he was about to do - the vlogger boy was still on screen at the waterpark. And that he suddenly had a boner. That had to be related, he couldn't blame it all on just merely thinking about the experiment. The Vidtuber boy_was_ pretty cute.

He fondled his necklace for a few more moments, before standing up with a sigh. Maybe a shower would clear his head. Preferably a cold one. He'd heard those sometimes helped with his occasional "down-there" problem.

*

Meanwhile, some miles away, a silver sedan was pulling into the parking lot of a depressingly brutalist building. In spite of its stark and thoroughly not-fun architecture, it was the largest recreation center in the town.

After finding a parking bay suitably close to the entrance, the sedan's driver switched off the engine, braced herself, and quickly threw open the door. With an involuntarily squeak, the thirty-five year old vixen darted through the rain to the main entrance, her high-heels clacking loudly on the wet blacktop and threatening to damage ankles.

Shoving the door open, the vixen stepped inside without delay. Immediately, the sound of the rushing rain was replaced by the sound of squealing shoes on basketball courts, the relentless bouncing of balls off various surfaces, and the cacophony of dozens of young voices intermingling in the echoing rafters. She wandered through to the back, peeking in on the occupied courts one by one as she shuffled down the corridor's sticky carpet.

The few moments in the rain had done an impressive job of soaking her favorite pantsuit, and she cursed her own forgetfulness under her breath. How hard would it have been to take an umbrella from the university office?

A perky young voice stopped her mood from darkening further. "Aunt Jolie! Over here! Hi!"

She turned around to see her nephew bounding towards her, clutching his far-too-big sports bag loosely in one paw. The fox boy's long tawny-blonde headfur bounced around him and his massive grin. He managed to dramatically skid to a halt on the carpet, his knee-high blue soccer socks providing the necessary protection.

"Hi Nephew Tyler," chortled the vixen, her own grin no less wide. "Careful, you shouldn't run around in socks like that!"

"I'm used to it!"

"I'll say. I don't think you ever take those things off."

"Well, sometimes I take a bath." The eleven-year-old smirked. "Sometimes, you know."

"I do, you little stinker! How did practice go?"

"Awesome! I like indoor soccer, it means on days like this we don't have to get drenched just to play." Tyler hitched his sports bag over his shoulder. "Don't like having to get up so early during the break though."

"Nobody likes getting up early. Are you excited to help me out again today?"

Immediately, the fox-boy's expression grew conspiratorial. He glanced around. "Will it be like last time?"

"I'm afraid so, yes."

Now Tyler's smirk became shy and he squirmed, scuffing the floor. "I-I've been looking forward to it," he admitted. "Are we going right now?"

"Sure, you can have a shower after we get you to the lab." The vixen laid a tender paw on the boy's slight shoulder.

"Juuust one thing." Tyler frowned. "Are you gonna t-tickle me like that again? Because I think I'll go crazy if you do that."

"Oh no, this time it's something slightly different. But I wouldn't want to disappoint you, so we'll revisit the idea later."

The kit immediately flushed, scrunching at the carpet below with his toes. A muffled snicker escaped him.

Jolie simply laughed. "Now let's get going. Just as soon as I take an umbrella from the lost and found... Nobody will mind, right?"

*

"Where did you get this car?" Kai mumbled, kicking at the litter on the floor of his sister's vehicle. "A yard sale?!"

"It cost me less than a month's fur-care products, give me a break." His sister brushed her lush blonde headfur out of her face, it having been jolted in front of her eyes after the automatic transmission attempted to make the twenty-year-old hatchback hop like a drunken kangaroo.

Kai raised his bare paws and crossed them in front of him. "I'm betting the floor is just gonna fall off."

"You're just nervous, aren't you." It wasn't a question. The teenager giggled. "Admit it, you're looking forward to this. Perv."

The tween fought off an embarrassed smile. "S-sure, I guess. But it's kinda weird, Sandy."

"What, being naked in front of the nurse and doctor?"

"Yeah, and, you know. They made me, uh, cum like ten times or something." His voice almost disappeared as he tried to say the c-word to his big sister. It barely qualified as a mumble.

"Oh, I know, I read all about it." Sandy shot him a sympathetic glance. "You did good, that couldn't have been easy. But, look, if you really think it's weird and don't wanna do it, I don't wanna make you. I get it. It's gotta be your choice. I'm only asking you because I don't exactly know many boys your age, you know?"

Kai shook his head firmly. "Uh, no, sure, I'll do it. I know it's helping you out. It's just, I guess I'm nervous. You haven't told anyone about it, have you?"

"No. Of course not. But there was another boy who contributed in another experiment. In fact, he's due for a test just before you, we're running two experiments today."

Kai felt his heart skip a beat. Another boy might see him there? And know what he was there for? "Oh, shit."

"You won't have to see each other if you don't want." Sandy shrugged. "But he's not going to judge you or anything. Believe me, they put him through the wringer worse than you. He's the nurse's nephew. Cute little dude, actually, I met him not long ago. You guy's'd get along!"

That reminded him. The leopard boy shifted slightly, falling silent for a moment. Thinking how best to phrase his query. Still, when he actually spoke, he immediately wanted to kick himself, easing into the subject with the subtle grace of a runaway train.

"Sis, what does 'gay' actually mean? Like, to be gay. I mean, I know what it means, but like, what does it mean? Exactly?"

The teenager blinked, raising an eyebrow and cocking an ear, though keeping her gaze on the road. "What do you mean? How _don't_you know that?"

"Well, I mean, our school didn't talk much about it in sex-ed. And we always use it as an insult or to say something is bad. Does it mean someone who is attracted to other boys or like...?"

Without indicating, Sandy swerved across two lanes. "Yeah, but only other boys. Or other girls, whatever you are. Everybody is on a scale of sexual attraction - from being totally attracted by members of the opposite sex, to being totally attracted only to members of the same sex." There was a pause. "So, if you were interested in other boys-"

"I didn't say that."

"Buuuut if you were, and you were still interested in girls, then you're not gay. Then you're bi. Or pan. It gets complicated."

The kit nodded. "So... why do we use it as an insult?"

His sister gave it a moment's thought. "Probably because you've heard others do it. Some people wanted to make kids think being gay was bad, and making the word actually mean 'bad' to them just by using it that way around them all the time was a pretty clever way of doing it. There are lots and lots of assholes in this world, Kai, and they _really_want you to be an asshole just like them. It's lonely on Mount Fuckhead." She left him with that thought for only a moment, before, suddenly, "Did you want to meet the other boy? The other one scheduled on to help us out today?"

He frowned. "What? I dunno. What if he recognises me?"

"You're not that famous, bucko." His sister snorted. "And besides. If you're both going through the same thing, like, maybe you'll be able to talk about it together. I mean, you both went through the experiment, you have nothing to be embarrassed about to each other, right?"

Kai tried not to realise that his sister had seen right through his concerns. More importantly, perhaps she was right. After all, maybe he'd learn something about himself - and those rogue feelings he was so worried about. It would be like ripping off the bandage, instead of being scared of doing so forever. "You know what?" he murmured. "Why not. Sure."

"We can arrange that, yeah. I guess."

Yeah, he lied to himself, that went pretty well.

He felt his sister's eyes boring into him from the side as the car continued to scream down the highway, eight miles per hour over the speed limit.

Wisely, he decided not to meet them. The rest of the drive to the university was in contemplative silence, except for the sound of their vehicle struggling not to fall apart.

Tyler was absorbed in a game of Furious Gophers on his aunt's phone, waiting on her to return to the office. Despite being clad now in only his tank-top, shorts, and his trademark long socks, the fox-boy was slowly broiling alive thanks to the over-eager space heater his aunt had turned on for him before disappearing into the massive university building's corridors. He huffed, trying not to let it distract him, focusing on beating his previous best score.

Eventually, he could take no more. As the gameover music taunted him once again, he hopped to his feet and turned the tiny whirring device off, though it was too late; the room was like a sauna. Groaning, the fox boy flopped back into the comfy office chair and propped his socked paws up on the polished bureau before returning to his game.

He crossed his legs and focused. But before he could finish the stage there was a knock on the door. "Uh. Come in!"

His aunt opened the door, and got about halfway through her first syllable before she gave a choked gasp. "Oh my god, I'm so sorry, Tyler, I must've had that heater on maximum."

"I had to turn it off," huffed the kit. "I was gonna die."

"That's fine. It's a sauna in here." The vixen grinned and stepped over to her desk. With a chortle, she scratched at the boy's proffered soles through his vivid blue socks. To her delight, the boy gritted his teeth and tried not to move, his toes flaring involuntarily. Daring her to continue. "What are you doin, huh? Getting your paws up on my desk. I eat my lunch there, you know."

"Y-you can eat my feet. Gyaah!" Finally, Tyler burst out giggling and withdrew his feet from the desktop.

"We're almost ready. But there's another boy who is going to do the same experiment after you, and he just asked me something interesting." Jolie frowned thoughtfully, crossing her arms in front of her ample bosom. "Would you like to meet your fellow victim for the day?"

Tyler blinked. "Oh. Oh, uh, I dunno." He thought for a second. "I guess it would be okay, since we've both, you know..."

"Well, and you're both helping out our research tremendously. He was worried you might be too shy to meet him, so he's just waiting down the corridor. I'll go get him." She stepped out quickly, and Tyler heard her mumble something.

A short moment later, and a small form - albeit one slightly bigger than Tyler's - appeared in the doorway. A lithe leopard boy with neck-length headfur, blonde much like Tyler's, wearing boardshorts and a baggy _SwiftArgent_t-shirt, a stylish shark-tooth necklace adorning his neck.

Tyler smiled and stood, placing his phone on the desktop, where it continued to play the in-game jingle. "Hi!"

The newcomer returned the smile. "Hey."

"So they talked you into this as well, huh?"

"My sis didn't even tell me what I was_doing_ here the first time." The leopard snorted. "Name's Kai."

"That's a cool name. Way cooler than mine. I'm Tyler." Tyler paused. "Hey, wait a sec. Are you that surfer?"

The other boy seemed to freeze for a moment. "Uh, yeah. I guess."

"Wow, hey, yeah! I've seen you before, they have pictures of you at my mall, at that clothing store. And I've read about you in TeenRhythm magazine." Involuntarily, Tyler's sleek tail started to twitch. "That's so cool! I can't believe they got you_to do this! Don't worry, by the way, I won't tell _nobody! So, you didn't know, when you were here last time...?"

Kai broke into a huge grin, and his own tail started to shimmy a bit as well. "I, uh, my sister didn't tell me a thing."

"Oh no." Tyler raised an eyebrow. "Oh wow. So it was a total surprise? My aunt told me what to expect at least. Kind of."

"The nurse is your aunt?"

"Yeah." The fox-boy beamed. "She's awesome, right?"

"Uh, she's, uh... yeah."

"Hot, right? That's what everyone s-"

Naturally, that's when Jolie decided to walk back into the room. "Hi boys," she sing-songed. "Sorry, but we have a problem with the machine, we'll get it working again quickly. Are you alright to just hang around here for a moment? I can come tell you when to run to the shower."

The two boys exchanged glances, and after a moment they both shrugged.

"Sure, we can chill out for a bit." Tyler beamed even wider.

"Alright. Now, try and work out who wants to go first. The only thing is, this is not the same as you went through before. So make sure you brace yourselves!"

The fox-boy's eyes widened. "Uh-oh. Uh."

"Okay! Then I'll be back in about fifteen minutes. In the meantime, figure out who goes first - and gets to tell the other one what to expect. Have fun, guys!" And with that, the buxom vixen swept out of the room.

Again, the boys exchanged glances.

"Uhh. What's she talkin' about?" Kai frowned. "Do you know?!"

"I-I actually have no idea."

"That's not good."

* Fifteen Minutes Later *

It wasn't too difficult to fix the calibration error, and Nurse Jolie found herself humming her way down the corridor to her small office again.

"Knock knock!" she announced, rapping on her office door. Waiting a respectful moment, she opened it and was greeted by heartwarming sight.

The two boys were lying side-by-side on the floor in front of her desk, face down, arms crossed in front of them, and with their feet and tails bumping against one another's contentedly in the air behind them. As expected, her smartphone was squarely in front of them, as they watched a video. Some young vlogger, Jolie surmised from what she heard.

"Hey auntie," murmured Tyler, reaching out and poking the video silent. "Is it time?"

"Sure is!" The vixen couldn't help but smile. "You boys became friends fast."

"Eh. We've got a lot in common. And we've both gone through these experiments, it's like we're war-buddies."

Jolie snickered. "Hm. Well, when you put it like that." She scratched her head. "Well, anyway, we're ready. So who wants to go first? We gotta get a move on to get both tests done before they close up the university."

Once again, the boys traded glances. After a moment, they both broke into a pair of equally toothy grins.

"Actually, auntie," announced Tyler, "we were thinking. We couldn't decide who was gonna go first. So we decided, how about we both do it? Can't the machine do two at once?"

For a second, the happy-go-lucky nurse was dumbstruck. For the two friendly Californian boys to become friends quickly was almost expected; but this? Not so much. "Well, I..." She stared for a moment. "Uh. Well. Yes, actually, it can do that. Are you sure?"

It was the slightly older leopard that spoke up next. "Like he said, we both already went through this stuff. We already know the other has gone through it, so it seems kinda dumb to be shy about it. We'll both go together and then neither of us has anything over the other."

"And it might be fun, too." Tyler grinned again, tapping his socked paws together in the air behind him - and slightly shifting his hips.

Jolie felt she should've expected this. There was almost certainly another reason why the precocious boys were keen to be in the same room together under the influence of their tormenting machine. War-buddies indeed.

"Well. I'll tell you what." Jolie undid her suit jacket and walked over to lay it over the back of her chair. Noting that both boy's eyes seemed to flick away from her face for a split moment. "I'll talk to the doctor and set it up, if you're sure. It won't really cause any problems. In the meantime, you guys run on to the showers - especially you, Ty-Ty, you're still all sweaty from training - and get clean." She narrowed her eyes. "You could take turns."

"Um. We talked about that too. We'll go in together. It's quicker that way."

"Somehow I knew you'd say that."

"What? It's no different than showering after a match!"

"If you say so."

*

The boys wasted no time getting into the small shower cubicle near the lab. Though they hadn't spoken a word about it outside of agreeing to undergo the test together, they'd come to an understanding of what was about to happen - and far from being put off by the fact they'd just met one another, for some reason that only emboldened them. Thrilled them. After all, it wouldn't be the first time either of them pushed these sorts of limits with another boy; and it was possible they'd never meet again anyway!

Ushering Kai in first, Tyler made sure to scan the corridor before closing the heavy door and locking it with the deadbolt.

With only a brief, nervous glance at one another, reaffirming their naughty split second decision earlier, the duo pulled their shirts off simultaneously and set them upon the changing bench. In moments, the rest of their garments joined them.

Quickly, they rinsed off in the shower, spending only a few seconds under the warm water each, such that it took them longer to dry off than it did for them to get wet. Rather than worry about washing themselves clean, the two boys spent more effort on trying to steal glances at one another without being too obvious about it - but just obvious enough to gauge if the other was okay with it.

Kai found his gaze lingering on the slightly smaller boy's abdomen as the fox rinsed his face, especially on the fox kit's outward-poking navel and the distinctive-V, a contour visible through the wet, white fur, where his legs and taut tummy seemed to blend into one another, before drifting down to admire the toned, lean legs; and Tyler was equally as curious when they traded places, taking the opportunity to inspect the older boy closely once the water was in his eyes.

It was an unspoken trade they both knew was going to occur the moment they shut that shower door.

Eventually, they both stepped away from the gently cascading water, and a petite vulpine paw reached out to tighten the taps. It was time to get started, and neither of them could hold back their excitement for much longer.

"Uh, this is gonna be tough, isn't it?" murmured Kai a few moments after the shower went silent, a nervous smile on his muzzle. They both stepped out of the shower's depression and into the changing room section of the tiny room, reaching for their towels. "It was bad enough last time, how can they possibly get crazier?"

"Yeah," chortled Tyler, returning the smile through the veil of his wet, matted headfur. "But it'll be cool too, right?"

The leopard sniggered, bending over to dry his legs with one of the luxurious blue towels that had been placed there for them. "Hey, I like your headfur, it's pretty long. Must've taken ages to grow."

"Thanks! It gets in the way when I play football but I like it too much to cut it. I gotta tie it back." Tyler rubbed his head vigorously with his own towel. "Is that why you don't grow yours out more? For when you're surfing?"

"Yeah, it just gets to a point where it's too annoying. But you gotta have long headfur if you're a surfer, you know? It's a thing."

Tyler nodded, snatching his shorts and underwear from the bench. "Um, hey?"

"Yeah?"

"Are you, like, um, excited about this?"

"I guess. Wait, you mean, like?" The leopard boy straightened up, fiddling with the towel held in front of him. "Yeah," he admitted, eventually.

"I got a boner when I was thinking about it earlier," tittered the fox, sitting on the bench to slip his socks back on. Having forgotten his shorts for a moment. "I was in the showers after indoor soccer, everyone was around, I was like 'oh nooo, stop it, stupid dick!'"

"Me too, when I was at home." Kai consciously forced himself to put his towel aside - as with last time, modesty was starting to seem foolish. On cue, his dick decided to tingle as his blood started to rush south. "This time is gonna be different though, right?"

"Yeah, but Auntie hasn't told me how."

"Should you bother putting those back on?" Kai gestured at the fox boy's long sports socks, as he struggled to get them on and pull them back up to his knees.

"My aunt likes 'em. She's such a perv." The little fox's laugh rang out, reverberating from the shower room's tiles. "How funny would it be if we just walked out naked? And passed all the professors and stuff?"

Kai snickered. "They'd be like..." He mimed staring cartoonishly in shock. "'Whaaat thaa fuck kinda research are they here for?'"

"I'd be like, 'how ya doin'?'" Standing, Tyler swished his hips in strange inversion of the sexy head-turn he'd seen models performing in countless shampoo ads, only this time instead of flicking hair at the onlooker he was flicking something else entirely. With a snort, he picked up his shorts again and slipped his slender legs into the appropriate holes.

Stunned, it took a few seconds for Kai to start laughing. "I can imagine you doing that, yeah," he told the fox, reaching over to grab his own shorts. "Come on, let's get this over with."

"Hey, Kai?"

"Yeah?"

"Yoooouuu've got a boner."

*

"Alright, boys," declared a familiar voice, greeting them as they once again were led through the laboratory door, "welcome back!"

"Hi Doctor Gabriel," chirped Tyler, shooting the tweed-clad coyote a friendly smile. "How are you?"

"I'm doing great, Tyler. The last month has been nothing but research results and dinner parties." Doctor Gabriel patted his stomach through his sweater, getting to his feet. "I'm glad to have you both back, though a little surprised you wanted to come in and do the experiment simultaneously."

"Saves time, and we figured it would be fun."

The coyote smirked slightly. "Well, I suppose it would be, not that I'm judging."

"Doctor," the nurse chided him, locking the door.

"Well, anyway. Welcome back." Doctor Gabriel shook both boy's paws and led them over the inspection bed by the wall. As before, it surrounded by a half-pulled privacy curtain like a hospital or clinic bed, and at the foot of it sat the fearsome little nerve-stimulating device on its familiar trolley. Looking for all the world like an unassuming ultrasound unit. "This time will be different."

"How come?" Kai frowned. "My sister said it would be basically the same."

"But my Auntie said it was gonna be really different." Tyler gave an exaggerate shrug.

"Well, yes. I mean, they're both correct." The doctor picked up one of the long white cables attached to the front of the device and displayed it to the boys. At the end was a strange, knobbly protrusion of clinically white, compressible, plastic. Like a bird's talon, it curved slightly along its inch or so length, ending in a noticeably bulbous tip.

The boys both frowned in confusion. How could that do anything to their sensitive parts?

"Are you boys familiar with the prostate gland?" asked the Doctor, raising an eyebrow. "Perhaps heard of it?"

Kai nodded. "I heard it during sex-ed, but I got no idea what it is. They made that whole thing totally boring."

"Wow, how do you make talking about sex and dicks and vaginas boring?" Tyler shook his head.

Doctor Gabriel shrugged. "Probably very much on purpose, Tyler. They wouldn't want you having any ideas, or thinking that sex might be pleasant." The coyote put the odd appendage down. "Basically, it's a small gland that sits about an inch or so behind the base of a boy's genitals. It produces sperm, or it will when you get a bit older."

"Oh!" Tyler clicked his fingers. "I think they told us that!"

"I'm glad they did, but I'm almost certain they wouldn't tell you that stimulation of the prostate gland can be incredibly pleasurable for men and boys. Many guys can reach orgasm through prostate stimulation alone."

The leopard boy frowned, scratching at his stomach idly and lifting a paw to gesture quizzically. "How do they do that? It's behind the, uh, penis, right? It's inside of you."

"Well. You go in through the back door. Just go in a little bit and you can reach it from behind."

"Oh." There was a hiatus. The boys exchanged a startled look, and exclaimed in unison: "Oh!"

The doctor laughed. "Yes, that's what we're doing this time. It'll be quite a bit different. That's what this different attachment does. It's going to go up in there and stimulate the prostate. It won't matter that you're a little young, the nerves, muscles and neurological responses will be basically the same."

"A-and you're gonna try it with us because we can keep going, right?" Tyler shifted from paw to paw, trying to conceal his anxious excitement.

"Yes, yes. Though that's less of a problem this time, we could still use the data." Doctor Gabriel tapped the machine's trolley. "It won't feel as sharp as last time, don't be afraid of it."

"It won't be?"

"Well. Probably not. You're the first to try it." A switch was flicked, and the fearsome little device started to whine softly. "Why don't we find out?"

"Oh, dude," murmured Kai, before bursting into nervous chortling. "This is gonna be so weird."

"Are you still up for it, boys?"

Another exchange of glances. "I wanna know how it feels," Tyler murmured, fingering his shorts' waistband.

With a grin, Kai shrugged and pulled his t-shirt over his head in a single move, flinging it negligently at a chair in the corner, baring his taut body yet again. As a young model, that motion was almost instinctive - he was a _master_of the cocky, sexy shirt-toss. "Bring it on."

Encouraged and just a little bit hyped up, Tyler whipped his own shorts down and stepped out of them. In moments, his tank-top joined Kai's t-shirt in on the chair, leaving the fox boy in just his blue socks and slightly tented sports briefs. "We should have a competition!" he declared, now fingering his underwear's elastic while his tail swished energetically behind him. "Let's see who can hold out the best."

Kai tilted an ear, opening his board-shorts with the characteristic rasp of velcro. "Hold out? Against that thing?" He stepped out of his shorts and bent down to toss them onto the pile on the chair. "That's not even possible!"

"I bet it'll be easier this time, coz it's not directly on our dicks," Tyler opined, slipping his underwear off now. His semi-stiff furless erection waggled between his legs as he hopped around for a moment, then tossed the briefs over as well with a _fade-away_basketball throw. He straightened up, sucking his belly into a concave position as he looked down at his enthusiastic member. "Wow, hard already."

Kai paused, staring for just a moment. "Y-yeah." With considerably less gusto, he removed his own and shot-putted them onto the chair.

"Yeah, you are too!" giggled Tyler. "I bet our brains are thinkin' about what's coming and made us stiff in anti, er, anticipation."

Flushing beneath his fur, Kai simply nodded, and his dick decided to twitch again, stiffening up even more. He tried to will it to at least slow down, and not betray how horny he suddenly was.

What on Earth_was up with that fox? It was almost like he didn't care at all about what was going on here. Then again, maybe that was the problem; Kai _did, and it was sending thrill-signals from his brain straight to his dick. It didn't matter that Kai had probably spent more time in front of a camera than anybody else in the room; he usually did so without an overzealous boner exposed for all to see. The excitement was almost overwhelming, and it only got more powerful the harder he tried to hide it.

"You're ahead of the program, again," mumbled the doctor, rolling his eyes playfully. "Nurse, do you want to prep them?"

Kai looked around, confused. "We can't both fit on the chair though."

"Oh, we're doing it like last time we did it with Tyler," Nurse Jolie explained, breaking her appraising silence and walking over to the boys. "The curtain rail up there is really sturdy, and we need you both standing up. So we're just going to get those strong little arms out of the way so you can't interfere with the equipment."

The leopard boy felt his muzzle dry up like a lake in summer, and his heart skipped a beat. "Oh." He appraised the curtain rail warily; it was indeed made of thick metal, and was segmented by heavy vertical struts that extended into a metal frame embedded in the ceiling.

"Just have to hang in there for a few minutes. Literally." The vixen opened a drawer near the bed and withdrew some medical-grade restraints, padded leather cuffs attached to a strap of thick, unyielding nylon. "Did you want to be facing one another?"

Before Kai could even open his muzzle, Tyler blurted out: "Of course! How else will we know if the other guy was able to hold it off?"

"Okay. Can I have your arms, please, Kai?"

Kai's furless member twitched. He shifted on his paws, feeling that familiar thrill of excitement, the same surge of adrenaline that happened last time he allowed himself to be made helpless by the adults and subjected to their fiendish device. "S-sure."

Gently, Jolie encircled one of the slender boy's spotted wrists with a thick padded cuff, then tossed the other cuff over the curtain rail so that it hung by the heavy connecting strap between two of the vertical struts. "It's just like before, only you'll be standing up, and it'll be less intensse. Don't worry."

Kai nodded, and didn't resist as his other wrist was likewise ensnared. He did swallow audibly, however, when the comfortable manacles were tightened and locked in place with an impregnable steel buckle.

"Here we go." The vixen smiled as she unpinned another buckle on the connecting strap and began shortening it. Lifting the boy's arms over his head in the process.

His stomach fluttering like a flock of dizzy butterflies, it took all of Kai's inner strength to remain still as his arms were pulled almost taut towards the ceiling, stretching and exposing his lean body to the adults - and the other boy! - as the nurse seemed determined to remove as much slack as possible before locking its length again with the heavy fastener.

He desperately tried not to look down at himself, lest he drew attention to the suddenly tingling erection that jutted from his exposed groin, though he knew it was both pointless and idiotic. As if every pair of eyes in the room hadn't already appraised his slim, naked body and overzealous three-inch erection.

Though he didn't feel unsafe, the leopard boy suddenly felt very small. Suddenly keenly aware that he was naked, bound, helpless, strung up like a tuna at auction, and at the mercy of these adults who were both over a head taller than him. And between his legs was a few inches of rock-hard leopard boyhood, quivering in anticipation.

"Oh my god," he moaned internally, "I can barely hold still again, it's like last time..." Once more, he tested his bonds, a reflexive action more than anything; the comfy cuffs may as well have been made of titanium. He was certain he could struggle for a day and not get even a little slack.

The leopard boy gasped in surprise when he felt the vixen's finger gently press down on his erection, sending trills of sensation through his entire body for just a second before slipping off, making the three-inch rod waggle in the air for a moment and his knees buckle.

He glanced up and met the vixen's eyes, and his cheeks suddenly burst into flame - or at least they felt that way.

"Always glad to see young men excited about science," drawled Nurse Jolie, winking before turning to her nephew. The fox-boy was swaying from side to side, visibly struggling to keep his fingers off his equally stiff penis. "Now for you, jitter-bug."

Tyler literally hopped from one sock-covered paw to the other as his aunt repeated the process, fidgeting ever as his wrists were encircled and comfortably enclosed. His breathing was shaky and heavy, and a permanent grin was etched on his features.

"Okay, give me your wrists, and stop giggling." Jolie picked another cuff up from the nearby bed. "We can't leave Kai hanging."

Tyler extended his right wrist. "Okay, okay," he murmured, taking a deep breath. He flinched slightly when the cuff encircled his slender forearm, and he burst into giggles again when his aunt buckled it tight. "Oh man!"

The doctor laughed from the side of the room. "Just a bit nervous, Tyler?"

"Yes, sir!" As the next wrist was encircled, the kit's toes scrunched at the carpet involuntarily. His bushy tail swished behind him. "I dunno how this is gonna feel! What if it's as crazy as last time?"

"It will be very unnerving, let's just say that. But you both went through the normal attachment testing, so this should be bearable."

Nurse Jolie gave a knowing chuckle as she winched her nephew's skinny arms up towards the curtain rail, suspending the twitchy fox a few feet from his new friend and forcing him onto his toes as well. "Well, the grownups that tried it certainly found it unnerving." She stepped back and placed her paws on her hips, appraising the two stretched-out boys. "Give it a squirm, boys. Gotta make sure you're nice and secure."

The two boys exchanged nervous glances. Then, in unison, they tried pulling themselves free, jerking their wrists from side to side, scrabbling at the carpet with their toes and throwing their weight around, and even attempting a few pull-ups.

"Holy crap," Tyler panted, pulling his heels towards his butt and hanging from the curtain rail with his full weight. "Nope."

"Ugh, yeah, nope!" Kai chortled, pretending his voice wasn't quavering, lowering himself from his pull-up position slowly. "What kind of curtains is this thing built to hold?!"

"True story, but the architect had really bad handwriting, and when they built all the curtain rails, they had the measurements all wrong. Inches instead of centimeters or something like that." Jolie stepped over to the trolley and wheeled the device of doom over to the bed, situating it somewhat between the two boys, making sure to not obscure their view of one another. "And this one in particular is built right into a girder in the ceiling. We've had a two-hundred pound bodybuilder hanging from that rail." She flicked the power switch on the stimulator, and it started to buzz quietly, booting into diagnostic mode. "He was the biggest wuss."

"I think he thought we were damaging his precious equipment, if you know what I mean." The coyote doctor cleared his throat and picked up his clipboard. "We're not, by the way, this is perfectly safe. It's like revving a car's engine, only instead of an engine, it's your nervous system. Anyway, Jolie, the lubricant is back in the fridge unit over there. Oh, and you might want to warn them before you apply it, it'll be very cold. Or don't, whichever sounds more fun."

"Oh yes." The vixen sauntered over to the small bar-fridge on the desk. She pulled a pair of sterilized gloves from a small dispensing box next to it. "Okay, boys, this will be just a little warmer than arctic sea-ice and we're going to use a lot of this stuff so it just slides right up in there, so... Brace those cute little butts!"

Kai gulped loudly. "You're going to stick the thing, uh, now, up...?"

"Yes. It's not too bad - it's something a lot of men, and boys, especially teenagers, do just for fun, to get at the gland we're going to be stimulating." She retrieved a silvery toothpaste-tube like package from the fridge, shutting it with a muffled pomf. "So it'll be something new, but don't worry, it won't hurt you or anything, no matter how weird it is. It's something a lot of guys do to themselves while masturbating, actually."

"It's how gay guys have sex!" volunteered Tyler, beaming at his new friend. "Didn't you know?"

Kai flushed. "Y-yeah, I've heard, but, you know, I haven't had gay-sex before!"

The fox just laughed, hopping up and down to burn off some of his seemingly boundless nervous energy.

"I'll prepare the wriggly one first," declared the vixen, unscrewing the cap as she approached. "I think he's a bit more adventurous with these sorts of things." She paused momentarily, suddenly frowning in thought. "In fact, I bet that's what that little laugh was about."

Tyler laughed again, and gave her an exaggerated wink.

Kai just gawked. Boys his age did that? Really? Wait, was that what they meant? ... Wait, what?!

Moments later, Jolie lifted up the first attachment - connected to the familiar boxy device via a thick, braided cable, this time it ended not in the sheathe-like enclosure the boys were acquainted with, but something very different indeed. The boys eyed the white protrusion; roughly four-inches long and curved like a banana, it bulged slightly in the middle and tapering, ending in a knobbly point.

"This here is our back-door attachment," the vixen explained, tapping the tip. "It curves up into your backside, and nestles up against that sensitive gland we mentioned before."

"It looks like a bent dick!" commented Tyler, twisting slightly as he hung from the rail. "A big ol' bumpy dick."

"As observant and tactful as always." A generous smearing of the clear liquid - seemingly the same stuff both kits had seen last time they had been here - was applied all over the white protrusion. "Doctor, which one do you think will jump the furthest?"

"My money is on the fidgeting fox."

Jolie nodded, then knelt beside her nephew. "Alright, this probably really will feel strange, so try and hold still, don't freak out, and try not to pull away. It's not going to hurt. Spread your legs as wide as you can like that."

Gulping, Tyler gave a curt nod. He shuffled his legs outwards and perked his backside out as much as he could, given he was forced to stand on the balls of his paws as it was. He pinched his eyes closed as his aunt gently reached around to hold him around the waist with her unoccupied arm.

"Here we go."

He winced when he felt a cold, slimy thing_suddenly touch his butt. And not his butt, but his _butt. The kit's eyes flew open and he yelped as the lubricated attachment's rounded tip kissed his unprepared anus. Suspended as he was and with the adult's arm holding him still, he barely moved, and the slimy protrusion continued to press into him with steadily increasing force.

"G-gaahaa!" the fox cried, his entire body tensing and both knees suddenly trying to retract into his chest. Even that dramatic motion, however, didn't really change much - the attachment quite easily pushed its way through the ring of muscle, and he shivered as he felt the cold, uncannily slippery invader slip up inside him. "B-BRR! Oh shit, that feels weird! Ahh! Ah!"

The invader continued to slide through his insides for a brief moment, before it hit something inside of him. It touched that something, and Tyler froze instantly, his eyes jackhammering open and his legs giving out. A pressure suddenly built up within his groin while his aunt pushed and adjusted the probe, and the peculiar feeling he always felt those few moments before his own paw brought him to orgasm, that rushing feeling just as his body prepared to expel the fluids he wasn't yet making and engulf him in a blissful, warm fire, hit him like a freight train from nowhere.

That pre-orgasmic twitching and tightening of his young internal muscles happened all of a sudden, and at a breakneck speed, hitting a crescendo and hesitating there for an unbearable instant, leaving the eleven-year-old fox a hair's width from climaxing right there and then as sharp tingles made his entire body judder.

"Wh-what the hell was that?!" he exhaled, shaking. "A-Aunt Jolie?"

The vixen suffocated a laugh, then moved the attachment just slightly more, again bumping the preteen prostate. The kit yelped again, gritting his sharp, white teeth. With an insouciant shake of her head, she pressed a button where the attachment met the connecting wire, and a small inflatable bladder inside of the attachment expanded to keep it in place inside the quivering boy. "That," she chortled, standing, "would be our target for this experiment. Seems like yours is pretty sensitive. I hear it feels somewhat like that moment before you pop, right?"

Tyler slowly relaxed, panting hard and trying to look around his extended arms to see what was now embedded inside of him. "I-I dunno if I was about to pee or about to cum! Haa!"

"Most likely the latter. You know, if you stimulate the prostate just right, you can keep that feeling of almost-there going indefinitely. You know. Forever." The vixen stepped in front of her rattled nephew. "You know. Like if you were to use something to keep it stimulated, like a vibrator, or some kind of experimental nerve-stimulating magic box, you could keep that feeling going. And going."

The fox-boy's jaw slowly dropped and he started to wilt, letting the curtain rail take his weight. "Y-you aren't serious-?"

"Relax, hot-stuff!" Jolie winked before walking over to the machine, picking up the second attachment. "We wouldn't do that to you guys. Well. You'd better behave, anyway."

"I-I've never felt anything like that before!"

"I can tell! Better get used to it though, we have an experiment to run here. Or don't, whichever 'sounds more fun.'" The vixen started applying lubricant to the second attachment, fully aware that the leopard boy was staring at her with bugged eyes and a raging three inch boner that his lean thighs were incapable of concealing in his current position. "Are you wondering how it feels, Kai?" She deliberately met the kit's eyes and winked.

The surfer kit squirmed slightly, his paws balling into fists involuntarily. "I-I-!"

"It's okay to feel a little nervous about new things, _especially_things like this, in front of almost strangers," Jolie cooed, smiling gently. "Just as it's okay to sometimes feel horny and excited about them sometimes, especially if you see it happen to someone right in front of you. It's perfectly normal. Try and think of it like that. Your body is doing what it should!" Her smile grew wider. "Heck, I'd be worried if a good-looking young boy like you wasn't full of excitement and curiosity. Just relax, okay?"

For a moment, Kai was dumbfounded, paralysed. He managed to look over and meet Tyler's eyes - the slightly nervous but encouraging half-smile struck him more profoundly than he could ever explain. Once again, his embarrassment and anxiety seemed so...illogical and silly. In a way that a fully professional or clinical environment couldn't make him feel.

"This is gonna make you jump." The vixen knelt by his side. She met his eyes. "Are you ready, Kai? It's up to you. Just like last time."

The leopard boy's throat felt like sandpaper all of a sudden. "Y-yeah," he croaked. "Let's do it."

The nurse wrapped an arm around his waist as she'd done with her nephew, pulling the slight hips back. A gentle tug on his glutes from her paw exposed the taut pink star between his cheeks. He tingled all over as the crook of the vixen's arm pushed down upon the top of his straining erection, gulping in anticipation.

Despite expecting it, the moment the wet, frigid object touched his butthole, Kai yelped like someone had slipped a handful of ice down his boxers - or, in this case, up his backside. The vixen knew not to dally, and pressed on; literally. Clutching at the straps, Kai could only gasp as the device's curved attachment slipped into him as easily as it had his compatriot, the algid lube making its sudden invasion almost trivially smooth and weirdly pleasant. Unlike his new friend, Kai managed to hold still, clutching at the leather strap suspending him.

Until, of course, his own 'special button' was nudged too.

"Oo-aah!!" the leopard boy huffed, wincing. His groin muscles seized, tested by a burst of electrifying sensation. "Wh-what was-!?"

His bare toes clenched and scrabbled uselessly on the carpet, as that ineffable sensation, the tingling pressure of the moments before his entire body was lit aflame by climax, hijacked his nervous system. The leopard gasped a few times, squirming uselessly against the gentle hold of the adult female while his tail flicked useless in the air behind him.

"What do you think it was?" Jolie snickered, her paw soothingly stroking the boy's abdomen. Firmly enough to be able to feel the quivering young muscle beneath the dense fur, a fingertip lingering for a moment in his shallow navel. "Almost done. Hold on."

The retention bulb inflated as expected, and a moment later, the vixen stood, leaving the leopard boy trembling from the aftershocks of that brief 'tickle' deep inside of him.

Shaking his hips reflexively, Kai found that that the curved probe wasn't going to budge unless he could reach around and grab it directly, or maybe kicked at with his feet. Yet, almost any movement of his hips just made the slick, invading plastic bump shift over that mysterious point inside of him. Firing sparks of pleasure directly through his groin, reverberating from deep inside of him to - unsurprisingly - the tip of his enthusiastic boner. With a shaky breath, he stopped and just hung from the railing.

After all, he knew from experience he wouldn't be defeating the cuffs that gripped his wrists.

Straightening up, Nurse Jolie sauntered over to the same chair the boys had tossed their clothes. "There we go, boys," she sing-songed, carefully placing her jacket on the chair's back. "You're all ready to have those stiffies played like a fiddle."

The doctor, who had been occupying himself with some research notes and displaying seemingly indifference to the boys' dramatics, cleared his throat. "Alright, boys," he announced, standing up. "As with before, internal sensors in the probe are all we need for this one. This isn't as precise as the last time, so we can't say for sure what will happen; we can't exactly wrap your prostates up in the same way. As we undulate the current, some subjects have experienced recurring orgasms, others have basically experienced one long orgasm - with mixed opinions of the experience - and others have been kept in that precursory stage Jolie mentioned before for the entire duration. It very much depends." He folded his arms. "Since you boys are the first subjects to test this at your early pubertal stage, we don't know what will happen. So this test will go for about fifteen minutes, as it shouldn't be as intense as direct genital stimulation. We do several cycles of three sets of ten pulses at high intensity, which has a dual-function of both directly stimulating subjects with sensation and inducing rhythmic muscular tensing, both of which can trigger orgasm. I'm telling you this because I'm certain you didn't read the document explaining it all, if the ladies in your life even bothered giving it to you."

"Ugh," Kai murmured, shivering from a mix of barely concealed excitement and apprehension. "I really shoulda read that..."

"Always read the fine print! Especially when you're going to let mad scientists run experiments on you." He smiled.

Tyler shuffled some more, wincing as his movement made the probe inside him shift. "I-I thought we hadn't hit puberty yet? D-don't you have to be like thirteen or something for that?"

"Oh no, that's a myth springing from misunderstanding what puberty is. The hormonal changes starts around the age of eight or nine - not coincidentally when many boys discover masturbation, sometimes to completion, though sometimes it takes further physical changes before certain urges become a little harder to ignore." The doctor picked up a clipboard and started scanning the page clipped to it. "I suspect the misunderstanding prevails because people want to pretend that sort of behaviour doesn't exist in people under, I don't know, probably fifteen at the youngest. Some aren't comfortable with the idea of their children having any sexual identity at all, I suppose, they probably do their best not to think about it at any age. I know the reverse is true, even though you wouldn't be alive if your parents hadn't had sex. A very silly attitude, isn't it?"

"They both come from very progressive families, doctor." Jolie unbuttoned the collar button of her shirt, then the next one beneath it. "Whew, we have the heating on for you boys."

"It's always hot when I'm naked," blurted Tyler, smirking. He looked intensely cheeky, dangling, with his arms over his head, from the curtain rail in the nude but for his dazzling blue, knee-high, soccer socks, folded over just below his knee. His silly grin practically daring the adults to do their worst.

The vixen strode over to the buzzing machine on its trolley, laying a paw on it. "You know, the best thing about this little box here," she drawled, "is that I can stop your terrible jokes with the flick of a switch."

"But why would you want that?!"

Jolie snorted a laugh. "Brace yourself," was all she said. Then flicked that switch. "Calibration mode on, doctor."

The buzzing stopped for a moment. Then returned, at twice the pitch and volume. The boys tensed involuntarily, locking eyes for a moment.

"Ohh shiiit," the blonde fox whimpered at his comrade. "Are you ready?"

"Y-yeah!"

"Okay, okay, remember to try and hold it b-ACK!?"

Tyler stiffened like a bolt of lightning had struck him, then he started gasping, squirming helplessly against the cuffs that held his wrists over his head.

Kai stared bug-eyed as the fox-boy squirmed and shifted, his furless member twitching rhythmically between his legs, bouncing up and down with startling intensity.

"Haah!" breathed the dancing boy, pinching his own eyes shut. "I-it's p-pulsing! I-it's - oh, it's weird! It's weird!"

"It's just calibrating based on the reactions of your muscles and nerves," mumbled the doctor, again not even looking. "It'll find a good setting, then start ahead with that. If you like, you can feel what it's like when it's always on later. One subject earlier said it was like having a Tibetan singing-bowl behind his penis."

"A w-wha- AH!" The fox's entire body contracted, and his lungs emptied in a sharp gasp. He shivered violently, and his straining two-and-a-half inch penis did likewise. After a moment, he started gasping for air. "Wh-whoa."

Kai gave a comical squeak. Which turned into a nervous whimper when he felt the plug in his own backside start to vibrate slightly. "Oh, c-cr-aah!"

A sharp, electric pulse made him tense just as the fox had, and it sent what felt like a powerful vibration that first hit that sensitive node inside of him, making the muscles deep inside of him contract, then emanated all the way through to the tip of the leopard's quivering erection - it was like a tuning fork had been applied to that sensitive button, instead of the gentle contact that had already almost buckled his knees.

But then another followed less than a second after, slightly stronger. Again, Kai jumped. Then another pulse. And then, just as his new friend had, the leopard started gasping for air, squirming and dancing on his tip-toes as the device started zapping his prostate, again and again, bringing that tuning-fork like vibration and odd, near-bursting point pressure each time.

"H-holy shit!" he squeaked, raising his chin to the ceiling and scrunching his eyes shut. Leaning forward, he let the straps bear his weight and tried to ride it out. With each pulse, that pressure lasted longer, and the feelings got sharper. And with each one, the leopard boy gave a sharp, breathless gasp.

He was barely aware of the nurse watching him off to the side with a slight frown. He barely heard her comment, "Perhaps this will be a bit rougher on them than we thought."

Kai gulped in lungfuls of air, wincing as powerful shivers racked his body. "It feels really wei-eird!"

"I told you!" panted Tyler, watching the bigger boy with undisguised interest.

The leopard boy slammed his eyes shut and clutched at the straps binding his arms to the overhead rail. But no mater what he did, the pulses, spaced about a second or so apart, made him gasp loudly and tense, his erection flapping upwards with each pulse.

"Almost done, Kai," assured the doctor. "Then it gets worse. But this part's almost done." With a beep, the device delivered one last shock to the leopard tween's backside. "There we go, it's finished calibrating. Now we can begin."

"B-begin?!" panted Kai, squirming like a fish on a hook. "I'm still shaky."

"Well, you better steel yourself, guys, if you think you can hold out against our machine, here." The doctor snorted. "Boys, we're going to alternate so that the machine can deliver its impulses with full power to both of you. I have no idea which one of you will go first. It's going to be a surprise."

The boys exchanged glances, trading nervous smiles as they twisted around to face their tautly stretched lean bodies to one another.

A thrill shot down Kai's spine and he flushed crimson under his fur, as the sheer eroticism of their situation struck him.The fox, in his vivid blue, knee-length socks, was trim and handsome. His shoulder length headfur was a gentle, feminine touch to his undeniably boyish form, and his flat stomach and prominent ribs were like irresistible magnets to Kai's eyes. And, of course, lower down, waggling in the air in front of his hips...

"Ready?" tittered Tyler, either not noticing or not reacting to being checked out. Shifting from side to side.

Kai swallowed, trying to wet his suddenly dry tongue. "Hell no."

"I'll be able to tell if you come, you know." The fox grinned.

"It ain't gonna matter. Last time I couldn't stop a single one even when, you know, when it kinda hurt?"

"This might be different, because it's on the other end. Maybe?" Tyler gave another nervous laugh.

There was another loud beep, and both boys glanced over at the unassuming white box on its trolley.

"Experimental program three beginning now, doctor," sing-songed Jolie, picking up a clipboard from the table. "Sensor data is being recorded. Let's see who goes first, shall we?"

Even though he expected it, the fox boy still yelped when the first powerful zap forced an explosion of pleasure into his young prostate. He let out a stunned, breathy gasp, his entire body vibrating with pleasure for a full two-seconds before being granted a moment's mercy.

"H-huunhh!" he wheezed. "Th-that waa- Hnnhh!!" Before he could finish, another pulse made him tense up like he was holding a live powerline. His coltish legs crossed and threshed, the hapless vulpine writhing as another few seconds of sharp pleasure swept out from deep within his backside. "Ahh!"

Kai stared in awe as the helpless fox squirmed, his lively erection throbbing straight out in front of him, piercing through the velvety white fur like a fleshy nail. The anticipation was killing him! How could it possibly be any weirder feeling than the calibration run?

As if to answer, Tyler stiffened and gave a strangled gasp as the machine launched into its third set of pulses, longer now, and coming closer together. He scrunched his eyes tightly shut and trembled, twisting and shaking his hips for several intense moments before all strength seemed to leave his body. He hung from the heavy-duty curtain rod, sharp gasps of what could easily be mistaken for pain accompanying the visible twitching and jumping of his youthful erection as it tried to eject what the fox boy's body was not yet making in any real quantity.

When the machine finally stopped, Tyler took a shuddering breath. He crossed one leg in front of the other, moving slowly, drained. Rubbing his still spasming erection against his thighs. "S-still tingling," he moaned. "So w-weird."

"Looked like you enjoyed it," chuckled his aunt. "Are you ready, Kai? You're up next."

"I-!" Before Kai got any further than that, a sudden pulse of warm, sharp tingling, accompanied by a powerful burst of intense pleasure radiated from deep inside him, and he immediately expelled all the air in his lungs. He gasped as another pulse hit him. Then another. Then another.

Stronger, more drawn out, than the calibration run. Lasting a second or so each time, with maybe a second in between them. Each pulse brought him to the edge of a climax and stole his breath away, and he immediately knew what Tyler had meant by tingling: the machine's pulses emanated from somewhere inside of him, and made his eager boner ring like a bell each time. Glancing down, with one eye closed, he could see "it" jump in time with the pulses.

Finally, the machine paused. Kai blinked, staring down the length of his stretched out belly. He was at the very cusp of orgasming already, a single second of touch would be all he needed to -

The machine started up again. Another rhythmic series of jolts, and again his body danced to its beat. The leopard boy gritted his teeth and shut his eyes, fighting back the inevitable climax. He'd seen what it did to the other boy; it would take another break, then hit him with a final set of pulses that'd last even longer. If he 'popped' before then, the machine probably wouldn't care, and wring a second intolerably intense one from him immediately after.

At least, that's how it worked when the orgasms were from directly touching himself. Maybe it would be different with the machine in his -

"G __a_ kkhh_!" Kai choked, as the device started yet again. This time, the pulses were a full second or so longer, and the duration between them shortened. Exactly as Tyler had done, Kai yelped each time the device electrically jabbed at his prostate, his eyes dinner-plate wide.

In mere moments, the inevitable orgasm flooded his body like hot molasses spreading through milk. He cried out, pulling on the straps holding his arms aloft, and danced helplessly on his tip-toes. His penis, feeling incredibly hot, stiff, and positively electrified, jerked and twitched in time with the bursts of sensual bliss. Spurred ever onward by the machine, which didn't even consider backing off once it had pushed Kai over the edge.

Eventually, he too hung from the railing, gasping for breath and with the remaining strength of a newborn kit. "H-holy shit..."

It wasn't like before. Stimulated from the 'rear-entrance', his climax had started there and swept through his entire body like a flame consuming a paper wick. Still intense, but spread throughout every inch of his being, burning at a slower, inevitable pace.

"There we go, boys," announced the doctor, scribbling on his clipboard. "You know what to expect now. Wasn't there something about trying to hold it off? A competition or something?" His tone was lightly mocking.

The two boys glanced at one another, their expressions doubtful.

"The sensors in the probe detect when your body does the various things indicative of an orgasm," the doctor continued. Pushing his wireframe glasses back up his greyish brown snout. "So, go ahead and try. We'll tell you who managed to hold out the longest at the end, if you want."

Tyler's tail started swinging from side to side. "Whatcha think, Kai?"

"A-alright, I guess."

"One last thing." Doctor Gabriel looked at them now, a smirk on his muzzle. "No more break-time. We'll be going one after another. Try and stay sane, alright?"

"W-wait, what do you-" Tyler blurted. But he cut himself off with a loud yelp, jumping as if he'd been touched by an icy paw. "Aaah! N-ngghh!"

The fox squirmed again, inhaling with staccato breaths as the device started its cycle again. He gritted his sharp teeth and pinched his eyes shut, hanging his head so it was framed by his long, blond headfur. "N-no, g-gotta-!" he squealed quietly, balling his little paws into fists. "Ah!Ah! Ngh! N-nnhhnn! Ohh..!"

The momentary respite came, and Tyler sagged like a sack of potatoes, dangling from the curtain rail. The pauses were designed only to give the subjects time to catch their breath, and prevent a continual climax, but short enough that their frazzled nerves wouldn't calm, nor their erections diminish. In seconds, the device started up again, and Tyler was right back to those cadenced grunts and the futile wriggling.

Kai stared, heart pounding in his chest and muzzle conspicuously dry as he watched the animated fox try to forestall the inescapable. Taking in every detail he could of the lithe boy's hopeless efforts.

Just as before, Tyler couldn't hold out for more than a few seconds when the device started its third set of pulses. His quavering, high pitch moan made Kai's already buttery knees even weaker, as he watched the other boy tremble through the aftershocks. "Ah! Ahh! Ahh-ngghhhh-nhh!"

But only a moment after Tyler stopped his involuntary gasps, the device turned its attention to the hopelessly horny tween leopard.

He, too, gasped aloud as the machine startled him with another powerful zap to his young prostate. Excited as he was, it only took one more: Kai squealed shrilly, his body set ablaze once again, pushed over the edge during the device's first round of pulses.

"Uhh! Uhnh!Uhh!" He grunted over and over, shaking uncontrollably as the machine continued to jolt his inner boy-button. Completely uncaring that he'd already been forced to climax. Scattering his senses to the four winds and dragging out the intense bliss.

When his eyes finally refocused, the machine had already started the next set of pulses, keeping his entire body swimming in tingles.

He panted, wriggling like a fish on a hook. "Unh. Unh!" He shook his head, clutching at the straps keeping his arms elevated. "Oh god, oh god! Ahh!"

"Hang on, Kai," he heard the vixen tell him. "You're doing so well."

The boy couldn't even respond, gasping in time with the machine's ministrations, his straining dick flapping upwards as his muscles danced to the device's tune. Gritting his teeth as he felt that familiar build-up of sensation, though its exact location in his body was anything but familiar. "Oh no-no-no," he whined, tip-toe dancing again. "It's coming again! W-wait! D-don't..."

But his pleas fell on deaf, mechanical non-ears. In mere seconds, his penis, and seemingly everything nerve around it, was ready to "pop" again. Still, through his post-orgasmic haze, he realized something.

Unlike last time he had been at the machine's mercy, or his nightly 'relaxation' sessions, the blooming, rushing feeling of orgasm wasn't quite as intense, or accompanied by over-sensitivity or tiredness. Or even any momentary, slight lessening of his excitement; in fact, it was much more like those times where he brought himself to the very edge of that sizzling pleasure with his own paws and backed off for a moment, as the machine did after each set of pulses, to draw out the experience. He was almost back to the brink of climax immediately, pulled to the precipice's edge, like it hadn't happened moments ago - and yet it mostly definitely had!

Immediately, Kai understood how the devilish contraption could not only wring orgasm after orgasm from a victim, but keep them perpetually dizzy with pleasure. Those breaks between pulses were to prevent a never ending, simmering fire of bliss from melting his mind. To break up what could be a pleasure unending.

What would happen if they -? Could he ask them to -?

As if the mere thought of that was too much, the leopard boy's eyes rolled back in his head and shuddered out another disorienting anal orgasm. It swept through his nerves like a grass-fire, reducing him to uncontrollable trembling. He grunted breathily, his young member bouncing in time with his quiet vocalizations.

"Wow," he heard Tyler whisper, sounding awed.

Not that it registered. For a moment Kai's world was nothing but a roiling sea of tingling, strength-sapping pleasure.

Again, the device switched targets. Resigning to it, the fox pinched his eyes shut and clutched at the restraints holding his skinny arms safely out of the way. Gasping quietly to the rhythm of each zap once again.

A scant few feet away, Kai was blinking away the cottony fog that had swaddled his brain. Tired, overstimulated, and shaky all over, his gaze immediately settled on his vulpine comrade - inhibitions completely gone, and only semi-aware of where he was. But he still knew exactly where he wanted to look.

Dangling limply, the leopard boy found himself staring, muzzle ajar, as the fox boy began hopping up and down on his toes, as warming tingles suffusing his body. Kai's gaze drifted south, and he licked his lips unthinkingly as he beheld the smaller kit's smooth, stiff erection bobbing up and down, jutting enthusiastically from his ineffectually wriggling hips.

As the next orgasm crashed - visibly - into poor Tyler, Kai's heart plunged into his stomach. Despite being driven to a shuddering orgasm thrice against his will, not a single iota of his excitement had diminished. Drained and exhausted, yet his pulse was racing.

He watched quietly as the fox cried out; several short, sharp gasps as the machine did its work, dangling like a hooked fish. Resigned to yet another climax, quivering taut stomach seemingly sucking itself in towards the fox's spine. By now, Tyler's long headfur was a disheveled mess, damp straw shrouding his delicate shoulders, neck, and collar. His luxurious, gold-and-white winter pelt glistening with a layer of boyish sweat.

Kai swallowed a thick lump in his throat, taking in the sight of the panting vulpine. He almost leaped out of his skin when Tyler took a deep breath, slowly finding his feet... then met his gaze with a slow wink. And, a millisecond later, with a boyish giggle.

Despite himself, Kai burst into giggles as well, scuffing the floor with his bare toes. "Wh-what?!"

"Enjoying the show?" The cheeky vulpine hopped up and down, his boner wagging happily as he did. "I saw you lookin'!"

"Well," Kai murmured. "You're h-hot. Shut up."

The fox bit his lip momentarily. "I'm looking too."

The adults interrupted before the boys' honesty could go further. Doctor Gabriel stepped over to the machine and pressed a switch, cutting off the machine's gentle whirring instantly.

"There we go, boys," he announced, checking off something on his clipboard. "I think that's enough for now. The temperature light just came on, don't want the device to overheat."

To their own surprise, the boys exchanged a glance of what could only be called ambivalence - disappointment tinged with heavy relief.

"Did you enjoy yourselves?" chuckled Nurse Jolie.

The coyote placed his clipboard down on the table. "Let's pretend to be professional, at least."

The boys chuckled wanly, faint smiles on their tired faces.

Carefully, the vixen approached her nephew. "Alright, we'll let you down slowly. Being restrained like that for too long can make it painful to just cut you down suddenly, so take it easy."

One by one, Jolie freed her nephew's wrists from the cuffs. The boy gingerly lowered them to his chest, trembling noticeably. "'m all shaky," he mumbled. "Ow. Yeah, my shoulders hurt. Oww!!" He hissed, clutching at the tops of his skinny arms.

The vixen rubbed the boy's back gently. "I know. All the blood is rushing back in there. We need to think of a better way to restrain subjects and keeping the access to those interesting parts. One of the reasons why we keep these sessions so short."

"Interesting parts." Tyler snorted, absently reaching down to tweak his still stiff penis. "And you call that short?"

"Not as short as you." Jolie set the cuffs on the nearby physiotherapy bed - unused today. "You know what? One second, Kai, I'll get some hotpacks warmed up before we let you down."

"Okay," mumbled the leopard boy. Too tired and cloudy-brained to complain about the delay - his entire body was flushed hot, and he couldn't help but shift and squirm from side to side, gentle tickles washing over his body. Some from the remnants of the powerful climaxes he'd been forced to endure, and some from his fidgeting causing the probe in his behind to rub against his overstimulated prostate. Still caught in his floaty afterglow, the boy barely realized he was doing it.

After massaging her nephew's slender arms, Jolie patted his equally skinny backside. "You okay, Ty-Ty? Feeling a bit wiped out?"

The fox sighed, rolling his shoulders. "I'm okay, Jo-Jo."

All of a sudden, the atmosphere of the room was shattered by the muffled melody of a jaunty ringtone. Doctor Gabriel blinked in astonishment, clutching at his hip.

"Oh my, I thought I had put this on silent, sorry," the coyote muttered, digging into his pocket. He looked at the others, a wan smile on his face. "It's my realtor. She never calls unless it's important. Oh, I can't take this in here, that'd just be - I'll just head off to the office. Sorry, Jolie, you don't mind, do you?"

"Of course not, doctor."

Urgently, Doctor Gabriel shuffled quickly over to the door, unlocked it, and quickly peeked outside. A moment later, the middle aged coyote slipped through into the corridor beyond with surprising agility.

Once again, the two boys exchanged amused glances.

Shrugging, Nurse Jolie turned around and walked over to the desk on the other side of the room. She picked up the touchscreen tablet that was lying there and jabbed at the screen. "Hrm. Well, short competition or not, we have a clear winner. Looks like the machine squeezed one more out of Kai there."

"I saw that," added Tyler, completely unnecessarily, propping his paws on his hips. "Got a two-fer-one deal that time, didn't he?"

"Yes, looks like it." The vixen smirked at the still restrained leopard boy. "What happened there, I wonder?"

Kai squirmed again, fending off a sudden shiver as the probe nudged his young prostate again. "Nh! Um, well, I dunno. It just happened twice really fast."

"Well, that can happen, especially if you're really keyed up. Kai, are you alright to wait for me to go get some hotpacks for you boys' shoulders? Do you mind if, forgive the pun, you just hang out here with Tyler for a bit? I don't want you to pull a shoulder muscle."

Kai's heart fluttered. "I guess."

"Don't worry, he doesn't bite," chuckled the vixen. "Seriously though, you can say no. I can just take you down now, or wait for the doctor to get back. Are you boys okay being locked in here together for a few minutes?"

Reflexively, the boys glanced at once another. There was a slight glint of mischief in the fox's eyes, but Kai thought little of it. "Sure, it's okay. Not like he'll see anything new."

"That's true. Thank you very much for supporting our research, Kai. This is definitely very intimate stuff, and I'm so happy you two got along so well." Jolie clasped her hands. "Okay, boys, just amuse yourselves until we get back. You know the rules, Tyler. You're in charge, don't touch anything you don't know how to use."

"Yep."

Making sure to first lay her phone on the desk along the far wall, the vixen hurriedly slipped out of the door to the corridor beyond, directing her nephew to lock it behind her. Which the nude fox-boy eagerly did.

Kai blinked away some of the wooziness and stretched as best he could, still bound to the overhead railing. "So," he asked, using the straps around his wrists to pull his body upright for a moment, alleviating the stiffness in his arms. "What rules were your aunt talking about there?"

"Oh." Tyler skipped back over to the center of the room. "Well, you know. Don't touch anyone without permission. I dunno why she said that, I know that. Geez." The fox kit grinned. "So, now what do we do?"

Kai blinked, then snorted a laugh. "I dunno," he chortled. "I'm a little tied up here!"

"Yeah, I know!" Tyler sidled closer, propping his paws on his bony hips. "And yo __ooouuu_ u_ lost the bet."

Something from Kai's chest plunged down to the abyssal pit of his suddenly tight stomach. "S-so?"

"Well. I dunno." Tyler rubbed at his nose. "Maybe. I was thinking."

"Wh-what?"

The fox boy leaned in, and lowered his voice. "I know how to turn the machine back on," he breathed. "How about, as punishment for losing, I see how many more I can get out of ya?"

Kai froze, and every hair on his restrained body stood on end for a moment. "M-more?"

"You know."A boyish, excited titter. "Tickles. But not that kind. You know what I mean." He crept even closer. "And... um, would you-? You know. Have you ever-?"

Kai blinked. "E-ever what?"

"Had your dick sucked, duh." Tyler beamed. "What else would I do with you like that?"

At that moment, Kai allowed himself to glance over the other boy's naked body again - to his surprise, the cheeky fox was fully erect again. The tingling in his own loins meant he didn't even need to check between his own legs. It was almost like they were connected - or perhaps they were both insanely horny young boys, with a mutual attraction. "F-for real?"

"Yeah." The fox-boy just giggled, casting a pointed look where Kai hadn't bothered. But still, a shadow of doubt fell over his delicate features. "It's okay, yeah? I mean, you could tell, right? That I liked you?"

Their eyes locked, forest green on ocean blue. A silent exchange in a situation more absurd and fantastical than either of them had imagined, even in their pubescent, creative day dreams. The two searched one another's faces, and slowly a boyish grin snuck onto their faces in an impressive display of synchronisation.

It was Tyler who broke the silence. "Hey, did you ever read the contract thing they got us to sign before we did this?"

"Uh. I mean. Okay, I guess not. I'm not much of a reader."

The fox's eyes narrowed shrewdly, and he barely suppressed a giggle. "Lemme show you something." With that, he practically bounded over to the bench running along the far wall, and started rummaging through the paperwork lying there. His fluffy tail eagerly swiped at the air, and his naked backside shifted from side to side as he dug through the messy pile.

Kai observed him, taking the opportunity to examine the other boy's body from the reverse angle. He felt more at ease than he had in years; the adults had simply dismissed all shame and taboo, and Tyler seemed to disdain those concepts entirely.

Tyler spun on his heels and suddenly hopped back over towards the dangling leopard, his semi-rigid erection waggling in the air and a handful of paper sheets in his paw. "Okay, so, you might find this interesting." He held the paperwork up, jabbing at a specific paragraph with a finger.

"Huh?" Kai leaned forward, letting the straps take his weight again as he squinted at the puny font. "I can't read that from here." He paused. "And I'm not very smart anyway."

"Well!" Tyler's grin grew wider, lowering the paperwork. "Do you wanna knooooow what you agreed to? My aunt explained it to me."

"Uhh. I guess I should." The leopard boy raised an eyebrow. "What is it?"

With some ceremony, Tyler raised the sheet again. "Ahem. Okay, so. Uhh, where is it again. Oh. Okay." He cleared his throat, shifting his weight excitedly. "'Due to the nature of the experiment, and the goal stated in section two-point-two of determining the effect of prolonged exposure to the nervous stimulation, blah blah blah blah, the participant understands and agrees to the following: the operational personnel may disregard requests to stop the experiment or remove the restraints, and may_ignore_ protestations of discomfort - the operational personnel agree to use their judgement to limit the degree of any possible harm or distress, with all due con--'"

Kai blinked. "Wait, what does tha-" He trailed off, his eyes slowly widening. "W-wait! No way!"

"Yup. You agreed to let them tie you up and leave that on for as long as they wanted. Even if they were driving you crazy. Even if you begged them to stop, you said they could ignore you. You agreed to it."

Kai felt his stomach invert, almost like he'd plunged off a cliff. "A-and you agreed to it, _after_reading that?"

"Well, yeah. I was kinda hoping they would, actually." Tyler absently pushed down on his still straining erection; as he did, his foreskin was drawn down, exposing the soft purple of his tip and stopping Kai's heart momentarily. "I think it's hot, being tied up and having someone just put you through that and you can't stop it. But auntie didn't wanna. Her 'professional ethics' or something. Just seems like an excuse to me, like she thinks I'm a big baby."

The hanging leopard boy swallowed, and found himself speaking before he could stop himself. "I-I kinda like the idea too."

Tyler actually burst out with happy laughter. "Awesome! Now wait until you hear this part..." He pointed at a lower paragraph. "See this? 'The operational personnel may, in ex- uh, ex-ten-uating circumstances, delegate operational control to another member of the research staff or other responsible party.'" He paused, smirking at the older boy. "Diiiid you hear what my aunt said when she left? Guess who's in charge."

After a moment, Kai literally flinched. "Wait, n-no, she also said not to touch anything -"

"That I dunno how to use. But I've read the_man-u-al_." Tyler sidled closer boldly. Kai whimpered aloud, realizing he could feel the heat from the other boy, especially from the cheery boner practically touching his own. "And you lost the bet, right?"

Lost, the leopard boy simply stared and squirmed. "I-I... I... wh-what you wanna do to me?"

Finally, Tyler shuffled even closer, boldly pressing his flat tummy against Kai's. The contact was electrifying, and Kai jumped like he'd stuck his tail in a powerpoint. Their erections pressed together in pinpoints of intense heat, and Tyler gently touched the older boy's chest.

"Exactly what I said. Alright?"

Kai forced himself to swallow, for another comical gulp. "I guess I got no choice, huh?"

The fox shuffled closer, grinding his own member against his new friend's, between their flat tummies. Intimately reaching behind the older boy to hold himself closer in a loose embrace. "Nah. Ready?"

"Bring it on."

"Alright, let's see."

Abruptly, Tyler turned and stalked over to the little box on its trolley, a cable still running from its now silent chassis around to Kai's tingling backside. With no hesitation at all, the kit flicked the largest switch on the little box, and immediately there was a loud beep as the device started its internal diagnostics again. "I wonder what program we should try next?" Tyler mused to himself. "Endurance? Maximum stim? That sounds kinda fun."

Kai's stomach inverted again. "W-wait-! No, it doesn't!"

"You're right, might be too much. Besides, there'd be nothing for me to do."

"F-for you to do? Whatcha mean?"

The device started its ominous whirring again. Tyler bit his lip and frowned at it for a moment. But then, his features lit up with certainty, and he quicky pressed a few of the buttons on the front of the device.

"What did you set it to? What did you set it to?!" Kai tensed.

"Oh, you'll see."

Kai hopped up and down on his tip-toes. Defying his anxiety, his erection waggled in the air. "C-c'mon, tell me!"

"Why? You'll know in a moment."

"You-!" Kai's exasperated response was cut off sharply when he felt the itching, tickling current begin in his backside. His eyes widened as the sensation grew, slowly, exponentially, like a creeping tidal wave creeping upon the shore. "N-nh! Nnnyyaah!" He hopped from foot to foot as the device created a singularity of pulsating pleasure just a few inches up into his backside. "T-Tyler!"

The leopard boy grit his teeth in fearful anticipation, tensing all over as his body reached the brink of another climax. However, the machine's electrifying output slowed and leveled out. Leaving Kai feeling like he was steeping in a hot bath of intense pleasure, an inch away from the familiar hot relief of another fluidless orgasm. "Ah-Ah!"

Tyler smirked, watching the older boy dangle from the durable rail, hopping uselessly on his tip-toes and biting his lip. Behind him, his languid tail twitched and flicked through the air like an unrestrained garden hose.

"In this mode," the fox whispered, "it can tell from how your muscles move how close you are to cumming, and keeps you just away from it. You might pop, if you try really hard, but it ain't gonna stop if you do."

"Oh shit!" Kai winced and peered pitifully at his new friend through one sea-green eye. "Haa! P-please, don't let it-!"

Yet Tyler just stepped right up to the dancing leopard, his warm, slightly sticky fingers slipping around his waggling boner. He smiled, the older boy's horny whimper music to his perked ears. He drew his fingers over the soft skin, curiously fiddling with the hot organ and gently inching the foreskin down to release the straining glans. "Of course not. Coz I'm gonna do it." He rubbed a thumb over the leopard's purple tip in a tight circle. "I like doin' this to myself. How's it feel?"

"G-gyaahh!!" Kai stiffened, and he stopped his frenetic dancing. He shivered in place, daring not to move while Tyler's fingers played with him. He bit his lip and trembled. "T-Tyler, I'm gonna-!"

Tyler stopped, pausing to take in the leopard's desperate expression. "Gonna what?"

The device reacted, undulating and adapting its power based on its sensor data. Detecting Kai was close to another knee-liquifying release, it backed down, its persistent whine quieting. Still, it didn't stop entirely, not even close; like a simmering, whistling kettle, Kai was kept on the edge of boiling over again. He gave a high-pitched, though primal and frustrated groan, shifting his thighs in a vain attempt to... to... He wasn't sure! Was he trying to dislodge the probe in his backside, or desperately rub his rigid boner?

A gentle paw touched his chest, then stroked down his side, coming to rest on his hip."Gonna what?" The fox's voice was smoldering, yet tender. Teasing, but encouraging. Composed, yet undisguisedly horny.

"Uhhnnh! T-Tyler, it's so-! I, uh-!" Momentarily, Kai's vision blurred, and he started to wilt. Behind his rolled back eyes, he was floating in an endless sea of pre-orgasmic bliss, his consciousness slowly diffusing into it like dye through water. "I-it feels nice b-but-! I gotta-! Nyyhgh!"

Tyler brought a paw to his chin, rubbing it thoughtfully and eyeing the delirious Kai up and down. His other paw absently sought out his own, stiff rubbery boner, and he stroked himself in both locations as he considered something. Without a word, he suddenly bent down and took the turned-down tops of the long blue and white sock on his right leg, and started working it down his lean calf.

Kai panted wearily, eyeing the fox as he expertly freed his toes. First the right, then the left, with perfect balance. "Wh-what? N-ngghnn!"

Swinging those long socks through the air, Tyler strode around behind his dangling victim. "You're making a lot of noise," he murmured. "So I got an idea. Don't want someone to walk past the door and hear you."

"Hunh?"A moment later, a strip of thick, absorbent fabric invaded the leopard boy's mouth, filling his nose with the subtle but unmistakable smell of another early-pubescent male. Despite the constant thrumming of pleasure hammering his prostate, Kai gasped in surprise as it was pulled tight into his muzzle, and quickly tied at the back of his head. "Nggnhg?! H-hylhherh?!"

"Don't worry," came the sultry response. "I'm just gagging you for a little bit. It won't hurt. I won't hurt you."

Kai grunted, but hadn't the energy to struggle. The waves of pleasure were still buffeting his mind, and he felt like a tiny boat adrift in a hot tropical storm. He could barely moan as the fox boy tightened the sock into an effective cleave gag. The synthetic fibers quickly wicked away the moisture in his mouth.

Suddenly, his world went a dark blue, as the other sock was suddenly wrapped around his head. "Hold on, gotta be careful with your headfur..."

Oh no. He was being blindfolded too?! What was Tyler's reasoning for that?!

With another stiff tug, Kai's sight was effectively taken from him. Some light bled through the porous fabric, and it wasn't a perfect fit, but no shapes could be discerned through it. His pulse raced yet again, and his instinctive struggles were fruitless. After a moment, he gave up and hung trembling from the railing once again.

"I'll make you really tickle, now," Tyler whispered in his ear, pressing into his side, a stroking paw reaching down to caress the leopard's taut, trembling tummy. He pressed into the leopard, and let his paw explore. He felt the contours of the surfer boy's abdomen, stroked the quivering flank. "You're r-really hot..." He gave gentle squeeze of Kai's chest, and started to slowly draw his fingers around and over the soft pink buttons he found there.

By now, from his prostate, to his rigid three-incher, to the tips of his fingers, Kai's body was ringing like a Tibetan singing-bowl. Despite the heavy fog of sensation, the hot, slightly sweaty body of another boy pressed so sensually against him was somehow still powerful, something... special. A gleaming needlepoint of reality that pierced that fog like a lighthouse.

With remarkable patience, Tyler continued his gentle petting. Seeking out and brushing over every concentrated spot of nerves he could think of, and discovering some more in the process. He brought both paws to bear on his victim now. A ticklish, feather-like touch of the feline boy's armpit. Following the curve of his spine tenderly. A firm squeeze of the taut backside, careful not to disturb the embedded probe.

Groaning, Kai surrendered to Tyler's touch. Without even thinking, he stood on his tiptoes and pushed his chest forward. Nobody had ever touched him like this, he realized. It was so much more than just a mere cuddle. He was being explored, charted like a forgotten cove. The absolute center of attention, and it felt amazing.

Though it wasn't being touched, his erection was impossible to ignore. It throbbed and tingled to the tune of the thrumming machine, bouncing in time to its crests and falls. It felt fuller and hotter than it ever had before, except perhaps when the very same machine had been attached to it instead. Full of nerves crying out for attention, it didn't take long for Kai's moans to have a tinge of desperation, and his struggling began anew. This time, he tried to press himself against the other boy - instinctively seeking to grind against the soft, hot body against his own.

Finally, a small, hot paw gripped him down there. Firmly kneading. A vulpine muzzle burrowed its way into Kai's neck, and moist breath tickled his fur. A moment later, the caressing paws were back on his chest and back, stroking down the length of his sweaty body as Tyler sank to his knees.

When he felt that hot breath wash over his furless member, Kai let loose a weak, prolonged whimper. Barely able to restrain himself from thrusting his hips at the cheeky vulpine inspecting his privates. Deprived of sight, everything was so much_more_ than he could've ever imagined.

"I'm gonna do it," Tyler whispered, kindly kneading the young leopard's dick as he started down its smallbore barrel. Appreciating every vein and taking in every involuntary twitch, noticing how the bare flesh glinted under the fluorescent lights. "Really gonna..."

A second later, Kai cried out. A strangled gasp that was cut short by a quavering, muffled moan. His trembling knees gave out totally as his erection suddenly found itself gliding into a hot, wet vulpine muzzle, leaving him dangling from the railing again.

The squamous, soft tissue gently closed around his tingling dick, and Tyler began to suckle. At first experimentally, gently, probing and feeling the underside of the hot, fleshy member with his soft vulpine tongue; but a mere few seconds later more like he was trying to devour a stick of candy. A pair of surprisingly strong, wiry fox-boy arms encircling his backside and pulled him close.

His body like a steel trap, balancing on his tip-toes, Kai pushed himself into the hot, wet singularity. His senses focused entirely on his lightning rod of an penis. A few shuddering moments later, that rod was struck, and the his nerves overloaded. Another orgasm tore through the leopard boy's psyche, and his shuddering yelp went straight through the makeshift gag. All while Tyler busied himself, inching his head back and forth with tightly controlled movements.

After juddering and shivering like his tail had been jammed into a power socket, Kai wilted, again. Reduced to grunting and twitching as pulses of pleasure, accompanied by the familiar constrictions of his taut muscles, wracked his entire body, melting down his awareness into a hot soup.

The machine beeped once, its fans spinning down as it backed off again.

Tyler, however, didn't. He pulled the lithe leopard to him even tighter, shutting his eyes as he enjoyed the feel, even the taste, of the stiff, twitching member sliding back and forth against his tongue. Lost in his own world, he failed to register the other boy's weak gasps and ineffectual squirming, rough tongue fraying oversensitive, post-orgasmic nerves.

"Mnnhh! Nhh-!"

The penny dropped, and Tyler rocked backwards onto his heels, the stiff erection popping from his muzzle. "Sorry!" he muttered, wiping away the thin thread of saliva that connected his snout to the purplish-red tip. "Sorry, I didn't realize." He gently reached out and unthinkingly tried to pull the leopard boy's foreskin back into place, retracting his paw instantly as the leopard gave another muffled yelp.

Chortling, Tyler got to his paws. "Was that good?" he asked, his paw absently drifting south. "Hang on, I'll get the - oh!"

With a high pitched whir, the device's fans began to spin up again, and Kai yelped again - though this time it was tinged with a helping of despair - as another humming jolt was delivered straight to his abused boy-button.

"Don't worry, I've got it! I've got it!" Tyler lunged over to the machine and flicked the power button. The dreaded machine's noises cut out abruptly, like a vacuum cleaner yanked from the wall. "There we go. Hang on."

A moment later, the sock was removed from the leopard's muzzle. Followed a moment later by the one over his eyes. Kai blinked repeatedly, the fluorescent office light dazzling and harsh. "Ugh, d-dude..."

"Was that nice?"

"I c-can't feel my legs."

"Was good, huh?" The fox giggled. "Do you want me to help you down?"

Kai nodded with as much energy as he could, suddenly aware of the stiffness in his shoulders again.

Suddenly, there was a firm, rhythmic knocking on the door, and the sound of a key rattling its way into a lock. Nurse Jolie's voice echoed gently from the other side of the heavy, fire resistant door. "Can I come in, boys?"

"Oh, good, she'll have something for your shoulders." Tyler hopped back from the dangling older boy. "Come in, Auntie!"

The door was pushed inwards with a dull creak, and the smiling vixen slipped in. She held up a long cushion-like object, and the smell of hot wheat filled the room almost instantly. "Took me a little longer than I liked to find the hot pack, sorry." She paused for a moment, taking in the smirk on her nephew's face, and Kai's exhausted panting. Indeed, her sharp eyes didn't miss the glistening wetness between the leopard's unsteady legs. Yet, somehow, she managed to say nothing. "Ready to come down, Kai?"

"He already has," murmured Tyler, grinning as he sat on the doctor's chair. "Well, not the 'down' part."

Carefully, Jolie released one slender leopard wrist and slowly lowered the boy's arm, pressing the hot pack to his shoulder. "Thank you very much, boys," she enthused. "We got a lot of data out of that, and showed that our parameters were spot on." The other wrist was freed, and she gently pet the wincing leopard's head. "If you like, you guys can have a shower. Pop your clothes back on for the trip down the hallway, boys, and we'll get you cleaned off. Kai, your sister is on her way to pick you up."

Kai nodded, blinking away his daze. "O-okay." Despite it all, he suddenly felt a flush of embarrassment; he was still visibly erect, this time in no small part due to the hot nurse's equally hot nephew. Could she tell what had just happened? "I-I'm okay," he added, shakily making his way to the other chair and the neglected pile of clothes atop it.

"Tyler, we'll head off once Kai's been picked up."

"Sure. Am I still staying with you tonight?"

"That's the plan! My internet is finally working again, so, I'll order some pizza and we can have a movie night!"

"Awesome!" The nude fox raised both fists over his head in celebration. "But can we get, I dunno, kebab or something instead? I had pizza last night."

"No problem, I'm not married to pizza. Why a kebab, though?"

Tyler shrugged, crossing his legs so he could put his socks back on. Naturally, they were going on first. "I had one last week and it was sooo good. I think it was a doner, donur? Donna-kebab?"

"Ohh, yeah, that's my favorite. But you gotta try a lamb one."

"I dunno, I don't like lamb. If I'm gonna eat a non-ev, I don't want it to be a baby, you know? I just-"

A sudden hissing interrupted him, and the foxes glanced over. Kai was doubled up, clutching at his boxer briefs and holding them away from his waist. A moment later, Kai glanced upwards, his teeth grit. "I-it's sensitive," he whispered sheepishly.

A dumbfounded moment later, Tyler started to giggle.

"Hey," he chuckled. "Hey, Kai!"

"H-huh?"

"Maybe until it calms down you should let it... hang ten, surfer dude?"

"That was horrible," the leopard boy groaned. Then he started to smirk. "Why don't we just get in the shower so you can show me your ball-handling skills, soccer-boy?"

And, just like that, they were laughing together again.

The night was long, and Tyler was happy to be in his pyjamas of simple, warm, green flannel and reading atop his aunt's spare bed. Lying on his front, with the warm ceiling light set to its dimmest level, he felt sleepy from trying to focus on the magazine in front of him, but not sleepy enough to put it away and retire.

He turned page after page, taking his time to absorb the contents. Lost in thought. His bare paws gently tapping in the air behind him. It wasn't his own bedroom, but he was as comfortable as he ever could be - even if the floral sheets and curtains didn't quite match his tastes.

There was a brief knock on the door, and a moment later, his aunt's delicate face slipped between the door and its frame. "It's ten o'clock, honey," she told him. "Are you ready for lights out?"

"Almost. I'm pretty tired." The kit smiled. "I won't be up much longer."

"Today went pretty well, huh? Did it work out as well as you thought it would?"

Tyler nodded. "Yeah. He was as cute and cool as I thought."

"I guess you guys had a bit of fun when I was out of the room?"

"Maybe."

"Hmm. I should've known." The vixen laughed airily. "Alright. Don't stay up too late, love. We've got plans for tomorrow."

"I know. Love you."

"Love you too. Good night!"

"G'night."

The door shut with a gentle percussion. Tyler's angular muzzle split with a large yawn, and he slipped a paw under the nearest pillow, feeling around for his smartphone. He unlocked the screen with a finger swipe and settled it atop his magazine. The LED at the top of the screen was blinking purple.

"Hnh? Message?"

Another tap, and the message appeared on the tiny screen.

New Contact: Hey its Kai 21:32 want 2 hang out on saturday? 21:33 so board inside lol 21:33 we can hang 10 and u can show me ur ball-handling skills!! haha 21:34

Slowly, Tyler began to smile. A smile of genuine happiness. He had made a new friend - a friend with shared interests. Quickly, he tapped out his agreement to the idea and replied, though at some level he knew the leopard boy, who had been put through the wringer earlier far worse than he had been, was probably asleep now.

Hang ten... That was funny, on reflection. Now he thought about it, ten centimeters was about the length of Kai's...

The fox snorted a laugh, slipping the phone back under the pillow. With another heady yawn, he closed his copy of_SoCal Junior Surfer Monthly_ and carelessly pushed it to the floor. It fell to the carpet, open to the center article: a picture-rich interview of Californian's favorite leopard grom. Including a salacious changing-room conversation, where the cheeky blonde had clearly taken the chance to show off his SwiftArgent boxers for the camera. Probably a sponsorship requirement.

With a last burst of energy, Tyler hopped to his feetpaws and flicked off the light, before collapsing once more onto the soft mattress.

What a great - if exhausting - day it had been indeed...

As his mind began to wander, and sleep threatened to take him, the fox started to rock and grind against the mattress. His pleasant nightly ritual for as long as he could remember.

It never failed to lull him to sleep. And after a few short moments and a final, breathy sigh...
