#3 of Nume Undies

Ed is a shy, nerdy, gay mouse. Kevin is an athletic, outgoing, bi emerald boa.

Both are interested in the other, but Ed can't bring himself to ask Kevin for a chance. And Ed has a very specific idea of what he wants in a boyfriend...

Luckily, Nume Undies can help them both out.

This was an idea I've been kicking around for months and to be honest I've been a little worried about actually writing it. Trying a few new kinks on, along with some others I've had for a while.

Enjoy.


Edward's rounded ears and nose twitched and he turned at the sound of his name being called. He had been so absorbed in his task that he was surprised and almost dropped the books he had been arranging on the shelves. Standing at the little bookstore's counter was Kevin, an emerald boa that the gray furred mouse had known since high school. When he saw the athletic anthro snake, Ed actually did drop the books.

Kevin put the magazine he had been holding on the counter and came over to help the mouse collect the books he had dropped. The mouse felt his cheeks grow hot and his whiskers twitch as the snake's well-toned rear was exposed. It didn't help that the boa was wearing loose fitting gym shorts that let the mouse look as far up them as he wanted. Ed quickly kicked a book away from Kevin, reached down to pick it up, and hoped he wasn't obvious. With the books collected, Ed scurried behind the counter to ring up Kevin's magazine purchase.

For his part, Kevin smiled to himself. As a bisexual, he had to admit that the smaller mouse was attractive. But in spite of multiple efforts by the snake over the years, Ed had never made any real sign that he was interested in a relationship. Kevin paid for his magazine, thanked the mouse, and gave him a wink as he left. The snake's departure left the mouse alone in the store with his thoughts for company. He watched the boa, the guy he knew he could never have, and schemed.

Ed contemplated his plan for the final time. The logic seemed sound to him. Kevin had made signs that he was interested in a relationship- but as handsome as the green scaled boa was, he wasn't the mouse's preferred type. The snake was well muscled, but was lean and athletic- in addition he had a flat washboard stomach that you could grate cheese on. His arms and legs were muscular, but lean as befit the snake's chosen athletic endeavors of running and swimming. But for all that, he wasn't perfect- not to Ed.

But that would soon change. Ed reached down and patted the large box he had stashed under the counter, his paw landing right on the Nume Undies_address on the shipping label. Yes, that would change _very soon.

***

Kevin jogged at a brisk pace, his thick tail trailing behind him as he ran in one of the outer lanes of the gym's track. He found himself thinking about Ed. He'd known the skinny mouse all through high school and college, and kept in loose contact with him as the mouse had begun working at the small bookstore down near the gym Kevin went to. Kevin had to admit that the mouse was nice to look at, and had a nice personality- if he could overcome that terrible shyness he was afflicted with. Kevin shrugged internally as he thought about it. While he was wishing, he might as well wish that the mouse would put on some weight. Ed would be damn handsome with a lean athletic build like Kevin himself had. The snake smiled to himself. Maybe if Ed could overcome his problems, Kevin could finally learn if what he'd heard about the size of mouse balls was true. The snake was grinning as he slowed down and then trotted off to the showers. As he showered, Kevin decided that he wasn't going to wait for the gray mouse anymore.

Ed couldn't believe it, Kevin had come to the bookstore and invited the mouse to the snake's apartment for dinner. Though he was extremely nervous, the mouse had accepted. He picked out a nice wine, and brought the package from Nume. He dressed in a fairly casual solid color polo and black slacks.

A few hours later, he arrived at Kevin's apartment with his tail swishing nervously behind him. The boa opened his door, smiled broadly, and invited the skinny mouse inside. Kevin was dressed in a dark green polo that contrasted nicely with his brighter green scales and he wore black pants like Ed was. The polo was tight enough that Ed could see the snake's lean muscles clearly, and see Kevin's fairly prominent bulge in his pants. Kevin smiled as he set the dishes on his table as he saw the mouse's pants beginning to bulge as well. The boa said nothing about it and dinner passed without incident. After Kevin cleared away the dishes, Ed nervously set a small clothing box on the table.

"I... know it might be a little forward," the mouse stammered as his nose twitched. "But I know you've been training a lot, and I got this for you."

"Well thank you," Kevin replied. The boa's mind raced through what kind of gift could be "a little forward" and settled on underwear pretty quickly. He'd told the mouse his waist size at a party they'd both been at when he was attempting to get Ed to not be a wallflower. The boa opened his mouth to tease the mouse about it, but Ed looked like he was ready to bolt, so perhaps it wasn't a good idea. The boa decided against it and just smiled and began to unwrap the package. Even though he was prepared, he was still surprised.

It was a jockstrap: one with a red pouch, wide red waistband, and two thin red leg straps- but the pouch looked... odd. Kevin lifted the garment out of the box and gave it a feel. Rather than the thin, form-fitting fabric pouches he was used to, this one felt thick and... puffy. The snake raised an eyebrow and set the undergarment on the table.

"It's supposed to wick moisture away," Ed said nervously. The gray furred mouse looked studiously down at the table, though the boa could see his embarrassment in the rush of color to his ears.

"It looks more like it might absorb it," Kevin said with a smile to show the mouse that he wasn't upset or anything. "Almost looks like a diaper." He added with a laugh.

Ed laughed too, but it was a nervous "I know I've screwed up" laugh. He began to get up from the table, and Kevin was sure the skinny mouse would leave. The boa reached out his hand and took a gentle hold of the mouse's wrist. He looked deeply into the mouse's blue eyes, and for half a second wished that the legendary hypnotic powers furs claimed his species possessed were real.

"Please don't go," the boa said. "I like it. I really do. Thank you." For a heartbeat, he considered asking if the mouse would like to see him in it, but decided just before he opened his mouth that the mouse wasn't ready for that yet. Instead, the snake asked if Ed wanted to watch some TV. The mouse agreed and they each took an end of the couch, and Kevin turned on the television.

At the first commercial break, Kevin began to think about the jockstrap. He began to wonder if it would feel good to wear, if it would really wick away moisture like the mouse claimed. He wondered how he would look in it, and what Ed would think of him in it. Kevin began to think he might look good in it, and began to look forward to trying it on. By the time the show returned, the jockstrap was all the snake could think of. His mind was full of images of himself posing in it for Ed while the mouse jacked off. It was so hot to think about. He really should do that. Put on the jockstrap. Put on the jockstrap.

A few moments later, Kevin couldn't stand it anymore. He looked at Ed to find the mouse looking back at him. Ed gave him a shy smile, but one that seemed to be tinged with a bit of hidden knowledge. Kevin didn't notice that, and excused himself. He hopped up from the couch, grabbed the jockstrap and headed to the bathroom.

He closed the door, but didn't lock it. He set the new jockstrap on the sink, quickly began to strip and threw his clothes into the shower. Naked, the urge to study himself in the full length mirror momentarily eclipsed the desire to put on the jock.

He was much as he looked the day before- golden slit pupiled eyes looking back at him from a tall, lean, green scaled body. He was well muscled, with a clearly defined six pack and large thighs that proved he was mainly a runner. But it was his groin that captured his attention the most. Like all male snakes, he possessed a nice set of grape sized balls in a scaled sac. His shaft was hanging flaccid over his sac, the darker green of his tip contrasting with the rest of his body scales. His thick tail swished across the floor behind his paws. He was the epitome of reptilian maleness. He could have any male or female he wanted. He began to get aroused, his shaft stirring at the thought. And how much better would he look in the jockstrap? He could have any male under his tail if he wore that jockstrap.

What? Kevin wasn't a bottom, he was a top and a dom. Subby snake. Switch snake. Give, receive, boys, cocks. Subby snake. Give yourself to the boys. Put on the jockstrap.

Yeah, Kevin finally thought to himself. What guy wouldn't want him? And if he put on the jockstrap... Ed had gotten it, so he could absolutely get Ed if he put it on. He could be perfect for the mouse if he wore it. Kevin grabbed the jockstrap, stepped into it, and pulled it up to his crotch.

Kevin stared at his reflection in the mirror until his eyes began to go unfocused. The jockstrap did indeed look great- the red fabric contrasted so nicely with his green scales. And the jockstrap felt so good. The thick padding felt so good against his junk, supporting and cradling it nicely even though it did hide the shape of his shaft and balls a bit. He looked so hot. But he could look so much better if he was...

Get big. Muscles. Muscles. Get big, get a gut. Strong. Tummy. Subby jock, chubby jock. Give up control. Be a musclegut pet. Give up control. Let go. Snake pet, total sub.

_ _ After a moment of struggle, Kevin gave in to the voice. It felt so right to him. His tail lifted from the floor to over his head, exposing his tail hole to any male that wished to claim it. Like that mouse. The boa's shaft began to stiffen in the safe confines of his jock. Then, the sensations began.

His shaft and balls began to tingle and grow warm. Then the warmth and tingling spread out from his groin to his stomach, up his tail, down his legs, and through the rest of his body. It was a highly erotic sensation, and the snake shuddered and hissed to himself as his erection reached full hardness. His cock throbbed, and the snake thought he felt bead of pre escape from his shaft but the jockstrap absorbed it. Then he groaned as he felt a new sensation.

He felt like he was being stretched in all directions or like he was swelling. Get big. In the full length mirror, Kevin's reflection seemed to inflate as his muscles grew larger. He grew a little bit taller, but his thighs and calves swelled to what seemed like twice their size. His biceps grew larger, his pec swelled. His build quickly went from a lean runners build to the huge muscles of a body builder. Even his tail grew thicker and more muscular. His rump grew warm as well, and he felt his hips expand just a bit so that his stance couldn't help but show off his sexy rear. The warmth spread into his ass cheeks, and the snake felt them expand, filling with muscle and just enough fat to make the perfect bubble butt for any male to squeeze or plow. Kevin moaned aloud. Big snake, sexy snake. Subby snake. Snake in body, snake in pants.

His jockstrap suddenly felt even tighter. His erection pushed his jockstrap further away from his groin as it grew longer and thicker. His balls grew larger, almost doubling in size. If Kevin hadn't been absorbed in shuddering in pleasure and listening to the voice in his head, he could have marveled that he could now give horses a run for their money in cock size. Then the warm feeling retreated from his extremities and settled into his stomach.

Kevin groaned as he felt his stomach began to swell. His washboard stomach expanded, filling out with a layer of fat to bulge over his groin. He didn't really lose any definition, but just added a sexy gut to his muscles. Musclegut snake. Sexy chubby snake. Subby snake. Pet snake. Give up control. Let someone else be in charge. Sexy snake. Pet snake. Lose control...

His reflection looking back at him had completely changed: he had grown almost half a foot taller, and now had muscles that could rival any body builder with a sexy tummy on him and massive bulge tucked into a red padded jockstrap. He looked amazing, even if he couldn't remember what his name was at that moment. He flexed and showed off his new, powerful muscles as the voice told him to. He was so absorbed by the voice in his mind that he barely noticed that the bathroom door opened. The door swung open to reveal the sexy mouse he'd been thinking of. His cock pulsed at the sight and he whimpered to himself. The mouse's polo was unbuttoned, revealing just a hint of his gray chest fur and he was holding something in his paws that the snake couldn't see.

"Do you like it?" the mouse asked with a shy smile. Lose control, lose control. Subby snake pet snake. Give up control. Give up control.

He tried to nod, tried to say he loved it, but only a hiss came out. Give up control. _ He loved his jockstrap. _Not just a jockstrap. _ He loved his... _Pet snake in his diaper jock. Loves to give Master control. Pet snake's in a diaper. Diaper. He loved his diaper. Give up control. Use it. Let Master take care of everything for you. He takes such good care of you, letting you pee anytime you need to. Show him you love it. Piss in your diaper for Master. Use your diaper. Diaper jock snake.

The snake moaned as he looked at the mouse, and for reasons he couldn't understand, he tried not to listen to the voice. But after a time, it seemed so right. He felt his control over his bladder begin to fade, and with a gasp, he pissed into his diaper. His newly expanded stomach jiggled slightly as the muscular snake shuddered at the feeling of just how good it felt to piss himself. The diaper jock sagged a bit as it filled with his urine. The warmth of his piss against his junk was comforting and arousing at the same time, but the snake couldn't help but feel the heat of embarrassment fill his cheeks as he realized that he had wet himself in front of the handsome mouse. But even as his paws moved to cover himself in shame, he saw in the mirror that his diaper jockstrap was no longer just a solid red. As the diaper absorbed his piss, the words Diaper Pet appeared on the pouch. His paws returned to his side as his mind understood that that was who he was: a pet snake, in a diaper, and he had done just what a diaper pet was supposed to do- he had used his diaper.

Diaper Pet looked up at the mouse, who was now smiling a bit less nervously even though his tail continued to swish rapidly behind him. He even chuckled a little.

"So, 'Diaper Pet,'" he said as he began to hold up the object in his paws. "Well, you know what every pet needs?"

He unrolled the object, revealing it to be a very, very small black brief. It had good sized pouch on the front, but was clearly cut to just cover the equipment; had no sides to speak of, other than the waistband; and had a back that would leave just a bit of cheek exposed. The mouse smiled even wider, the shyness finally eclipsed by desire.

"A Master."

With that, the mouse quickly stripped- as if he was scared that his confidence and desire would leave him. Diaper Pet moaned in agreement and excitement as the mouse proceeded, Pet's cock throbbing in his diaper jock. Finally, the mouse stood naked before Diaper Pet holding the brief before him. The mouse was a foot shorter than Diaper Pet in his newly expanded musclegut body, with short gray fur, rounded ears, and beautiful blue eyes. The mouse was slender, with no muscle to him at all: Diaper Pet thought he could see the outline of his ribs through his fur. His pink cylindrical shaft with its mushroom shaped head was just beginning to sexily poke out of his sheath over a set of balls that had been about the size of Diaper Pet's before he became Diaper Pet- but on the mouse's thin frame, they looked massive. Diaper Pet's tongue flicked from his snout in desire. The mouse looked at him, swallowed, and then quickly stepped into the briefs.

Diaper Pet was disappointed for a moment as the brief seemed to be too large for the mouse, and the mouse's junk disappeared into the pouch. He had barely hissed that disappointment when the mouse began to grow. He grew taller, surging from having his ear tips at the level of Diaper Pet's large nipples to almost eye to eye with the big muscular snake. His calves expanded to the proper size for a runner, and his thighs bulged until they were thick and powerful. His furless tail lengthened and thickened to better balance the mouse with his new height and mass. And then, the mouse began to change into a truly perfect Master.

His hips expanded, giving him a powerful and confident stance. His stomach expanding into a lean six pack. His torso also swelled, the mouse's ribs disappearing under a layer of lean muscle. His pectorals expanded, and his nipples grew to size of nickels, teasing Diaper Pet with the thought of licking them. The mouse's arms swelled to a set of well-muscled biceps and forearms. On his muzzle the shy smile vanished, replaced by the confident smile of a Master.

But Master's most impressive changes were below his waist once he had filled out to an impressively lean, muscular, athletic jock. Inside his briefs, Master's rear expanded and filled out to a muscular rump worthy of worship. The changes in front were even more impressive. Master's crotch bulged out, the impression of his now large sheath became clearly visible in the black stretchy fabric. As it became visible, Diaper Pet could see Mater's shaft begin to emerge from that sheath. Underneath that sheath and shaft Master's balls swelled, going from the size of grapes to the size of small oranges that the brief struggled to contain. On the pouch, on Master's left hip, a rainbow Mars symbol became visible. The symbol reflected briefly in Diaper Pet's eyes, and he felt his sexual preferences slide more towards males solely. In the meantime, the mouse had become the perfect Master.

Diaper Pet stared at the handsome, athletic mouse with his mouth hanging open as Master flexed and posed for a few moments. Diaper Pet's eyes remained somewhat unfocused, so he didn't recognize what Master was doing: not until the mouse's paw landed on his snout.

"Boop," the mouse said with a confident giggle. His voice had dropped a few octaves to a sexy baritone. "Like what you see, Kevin?"

Kevin? Oh right, that was Diaper Pet's name outside of home. Kevin was the snake that went out and earned money, and shopped, lifted weights, played video games, and was interested in Master as simply Ed. Of course, Kevin would always wear his diaper jock, so Diaper Pet would always be with him. Diaper Pet Kevin moaned as he thought about how to respond.

"Yes Master Ed," the snake finally replied. "You are so handsome."

The mouse reached out and ran his paw over the snake's massive pectorals, teasing Diaper Pet's large sensitive nipples, and then ran it down his chubby tummy. Finally he reached down and fondled the snake's large balls and massive shaft through his soggy diaper, pressing the warm moist fabric against his groin.

"And you are absolutely gorgeous. I'm so glad you invited me over so we could do this," Master Ed replied. "You do want to do this, yes Kevin?"

"I do," Kevin replied as he put his own paw on Ed's chest, just over the mouse's heart. He was okay with this, even if the mouse hadn't exactly consulted him beforehand. He liked Ed, and had been absolutely willing to explore a relationship with him. If this was what the mouse needed to be comfortable, so be it. "I want us to be a couple."

Ed smiled and pushed the snake's paw down before pulling the massive snake into a kiss. Diaper Pet Kevin moaned into the mouse's muzzle as they kissed. The mouse felt so good in his arms and pressing into his chubby stomach. This felt so right. Finally, Master Ed broke the kiss and gave Diaper Pet a naughty smile.

"Okay," the mouse replied. "Well, I've never done this before and I don't think you've been a bottom. So, shall we take each other's virginity?"

Diaper Pet Kevin nodded and turned to present his rear to Master Ed. The mouse placed a paw on the snake's rump and rubbed it a few times before giving it a gentle slap. Diaper Pet giggled as he felt his rump jiggle from the impact. He swung his hips and raised his tail to put on a show. Master grunted in appreciation and when Diaper Pet looked back, he was going through his pants pockets. From them, he pulled out a condom and a small bottle of lube. The mouse sported a fully pitched tent as he returned to the snake.

Diaper Pet positioned himself in front of the toilet, bent over and put his paws on the top of the tank to support himself. He had just gotten himself into position when he felt Master's paw spread his cheeks. Then a cool liquid was spread over his tail hole, causing him to gasp. The gasp was repeated and turned into a moan as the mouse ran a lube covered finger over the snake's tail hole and then gently pushed it in. Diaper Pet moaned as Master moved his finger back and forth in his tail hole. There had been a twinge of pain at first, but now there was only a pleasure the snake had only seen in others. It felt so good to have something under his tail. He gasped again as Master inserted a second finger, and again there was a slight discomfort as his insides were stretched, but Master used plenty of lube and Diaper Pet's tail hole soon adjusted; besides, with that second finger in him, Master was hitting the snake's prostate, causing Diaper Pet's cock to throb and release a stream of pre that kept his diaper moist.

All too soon, the mouse's fingers withdrew. Diaper Pet whimpered slightly at the absence of something in his tail hole, but Master whispered encouragement as he pressed up against the snake's rear after a moment of being away. Diaper Pet moaned aloud as felt a new pressure on the sensitive ring of his tail hole- the tip of Master's condom wrapped and lubricated cock. After a quick pause and whispered question to make sure that Diaper Pet was ready, Master gently slid his shaft into the snake's ready hole.

Diaper Pet let out a vocalization that was something between a moan and a gasp that quickly went to a hiss as the mouse pressed deeper into his tail hole. The sensation was unlike anything the snake had experienced before: tingles and surges of ecstasy shot through him as Master began to thrust and mate him. The snake was quickly reduced to a moaning, blubbering state as the pleasure sent little electric shocks up his spine from the base of his head to the tip of his tail. It was amazing to experience, and he was unsure how he kept standing as the mouse mated him- he was sure that his knees would give out in his euphoria.

Master picked up his pace, thrusting quickly and deeply into Diaper Pet's rear. The mouse didn't forget about taking care of his snake, and leaned in and pressed his torso against Diaper Pet's tail. Master took advantage of his closer position to reach around the big snake's chubby belly and down to his groin to stroke Diaper Pet's long cock in his diaper jock. The snake could only groan and shift his weight as each confident thrust of the mouse's hips pushed his diaper covered shaft into Master's paw. Soon, they were moaning, grunting, and whining almost in time with each other as Diaper Pet felt the pressure of an orgasm beginning to build deep in his loins.

"Clloooosssse," the muscular snake finally managed to hiss.

"Meee... unfff... tooo," the athletic mouse replied.

The mouse began to buck his hips rapidly, slapping his hips against the snake's rear with the pace of a jackhammer as the pressure inside Diaper Pet built and built. Both the snake and the mouse began to pant as they continued the climb towards orgasm.

Master Ed reached his peak first, slamming his hips against his snake's rear and holding them there as he let out a squeak/moan in climax. Deep inside his rear, Diaper Pet Kevin swore he felt the condom inflate as the mouse's heavy balls emptied themselves into it. The increased pressure inside him brought the snake just to the brink of climax, but didn't push him over. Luckily, Ed wasn't so worn out that he wasn't attentive to his partner's needs, and a few more loving strokes from the mouse where all it took to get Kevin to hiss in his own orgasm. The snake unloaded into his diaper jock and the soggy garment began to sag away from his groin as it absorbed this additional liquid.

For a long moment, they just stood there panting, Kevin leaning heavily on the toilet, Ed leaning against Kevin. Finally the mouse pulled out and they somewhat wobbly moved to sit on the edge of Kevin's large soaking tub.

"Heh. No clean up required with you bottoming in a diaper," Ed said with a chuckle as he pulled the condom from his shaft. He tied a knot in the end and tossed the cum filled condom into the trash can.

"Yeah," Kevin giggled and rubbed his belly. "You really like big, muscle, chubby men?"

"Mmmhmm," Ed replied as he got to his paws and gave the snake a kiss on the cheek. "You are so beautiful."

With that, the mouse turned and put the seat up on the toilet and took a post orgasm piss. Kevin, who also usually had to pee after an orgasm, just smiled and used his diaper. With nature's call answered, the mouse turned back to the snake.

"You've put a lot into that dear," he said as he motioned for the snake to get to his paws. "Let's get you out of that soggy diaper."

Kevin complied and Ed pulled the diaper to the floor, leaving the snake's kiwi sized balls and six and a half inches of flaccid shaft exposed. Ed made a comment about it being a good thing the diaper jock was machine washable and tossed the garment into the tub, where it landed with a heavy splat. That done, Ed gave Kevin's equipment a pat and smiled at the snake.

"I'll have to get some practice in so I can handle that," the mouse thought aloud.

Kevin nodded. "I will look forward to it."

Ed smiled and stood on his toes to kiss the snake. Kevin returned the kiss and held the mouse close to himself. A moment later, they broke the kiss.

"I bought a week's supply of the diaper jocks," Ed told the snake. "We can look for other styles later."

"Alright," Kevin replied with a smile. He was looking forward to it. "Would you like to stay the night?"

"If you don't mind," Ed answered with a smile. "After all, we were in the middle of watching TV. Let's get you in another diaper and get back to snuggling on the couch and doing that."

With that, the mouse took the muscular snake's paw and guided him to back to the living room.
