"Fuck, sis..." Iolvin slipped over to his twin sister and dropped to his knees. "What ha-- No, where's the fucker that did this?!"

"Yoyo... Just..." Ari mumbled in a dry tone before coughing on some sand in her muzzle. "I want to go home. I need to get home..."

"Yeah but that--" Yoyo cut himself off when he realized just how badly his sister looked in the sand. "Right. You need to be safe first and foremost. Think you can stand if I help?"

"Uh... maybe."

"Good. We should get you cleaned up and back in your--" Iolvin took a look about and queried, "Wait, where are your clothes?"

Rolling her head limply from side to side, Ilaria looked about and seemed to become more distressed. "Bastard... took 'em?"

"Shit... Well fuck it, that swimsuit will do I guess." Hooking his arms under his sister's shoulders Yoyo lifted her up and toward the shower. "You alright here while I get your leg?"

Unresponsive and apparently in a fair bit of pain, Ilaria slumped against the wall of a stall and kept herself up. In her dazed state Iolvin fetched the appendage and strapped it onto his sister himself. The whole time he tried to avert his gaze, but the sight of blood only thwarted his efforts for decency. With Ari not responding he took the initiative and simply pulled her cock free of her pussy. The mixture of blood and cum that poured out concerned him, but he didn't want to press the harder questions at the moment. Instead, he flipped on the cool water and let it run a few seconds over Ari's fur. He honestly wanted to clean her entirely, but he also didn't know if she was hurting or whether she'd take such a move badly at the moment.

"Lulu, we're going to the car alright? I've got a first aid kit there for your face and... yeah." Yoyo focused at the empty, vapid stare he received back and sighed. "I know this is tough, but we can sort this out after we tell the others and take you--"

"No! Don't tell anyone!" Ari suddenly shouted back, starting to come back to her senses.

"Uh... sure, it's your call sis." Iolvin stepped back and eventually out of the stall as his twin regained herself, ignoring the winces of pain she exhibited for now. "We can't just leave them though. I drove, remember?"

Starting the water up again to clean the rest of herself with a very gingerly touch, Ilaria agreed, "No, I'll... I'll wait..."

"Sure... I'll keep you company though."

Soon enough, Ilaria stumbled out of the stall to grab her swimsuit parts from the sand. Iolvin averted his eyes, but handed her the articles of clothing she seeked after having already gathered them. Ari slipped the parts back on herself and made sure to properly adjust her male parts this time, then the two headed off to the back of Yoyo's jeep. Thankfully the first aid kit was where he remembered, and Yoyo patched up Ari's face and what he felt safe touching around her chest.

"Hey, what happened?" one of the others inquired as she headed over for a drink in the cooler. Always a good friend to the two, Robyn fell into her regular concerned tone when she saw the bandages.

"Ari went and--"

"I fell in the showers. Damn leg acting up again," Ilaria feigned.

"Well... huh." The squirrel adjusted her top a bit and reached for her drink, adding, "You're more of a klutz than me sometimes, ya' crazy bird. Be careful, yeah?"

"Sure... But I'm just gonna rest a bit. Still a little dizzy," Ari clarified.

Robyn cracked open her drink and took a sip as she walked back to the water. "Hmm? That's a shame. Such a cute bikini and you're not gonna use it?"

"Nah, it's better safe than sorry, right?" Yoyo chimed in. "I think I'll stay with her t--"

"Yoyo, just go. I... think I'll be alright." Ilaria looked to him as she pressed to her feet from the tailgate. "Yeah."

With a few silent nods between the two, Iolvin and Robyn went back out to the waves to splash and swim for another hour or so. The whole time Ilaria simply sat where the waves would rush into her, her brother keeping an eye on her from the water. When the group had their fill, they all clamored into the jeep and drove off. Ilaria was oddly quiet to the others but she just played it off as daydreaming for the most part. Eventually the others were dropped off and the twins made their way back home.

"Ielunschra Rivzhyet, what in the world happened to you?!" their mother demanded as they walked in the door.

"Lulu's not feeling well. She fell down," Yoyo spoke up on his sister's behalf.

"Yeah, I... just need to rest."

"Honey, is it anything serious?" Mom eventually drew a blown out scenario in her head, expanding, "We need to take you to the hospital."

"No, Mom... Yoyo took care of it all. I'm just tired." Spotting dinner on the stove Ari added, "Just save my dinner or something. I'll probably miss it tonight."

"Baby girl, you sure you're alright?"

"Yeah, just... I'm going to bed early."


Iolvin stretched a bit as he finished his class work for the night. Well, he finished it as best he could with his mind running off on tangents about his twin sister all night. The last he'd heard of her was the shower a few minutes after she ran upstairs. Yoyo just hoped she was willing to talk things through in the morning or after his classes at college. What happened to her couldn't just be shrugged away. Plus with her anatomy she already had problems talking to people. Yoyo would just have to bug her about it first chance he got.

Yoyo stood up and headed to the bathroom, knocking on the door even though there wasn't any light beneath the it. It was more of a formality and quite habitual, having grown up sharing a bathroom with his sister all his life. When there was nothing back, he popped open the door and locked the one opposite that led to Ilaria's room. As he pulled out his dick to take a piss, he reached over and turned on the shower so the water could heat up while he did his business. When he was finished he flushed the toilet and started removing his shirt, only then noticing his mistake.

"FUCK!" screamed Ilaria in the tub of the shower, having just been blasted with searing hot water.

"Shit, sis!" Iolvin backed up a second, then freaked out and hid his shame when he realized what was happening. "Oh, fuck, why didn't you say anything earl--? ...earlier."

"What? Oh..." Ilaria looked at herself then back to her brother. "I must have fallen asleep."

"I... You're not decent." Yoyo turned and started out the bathroom adding, "I'll just take a shower in the morning..."

Ilaria reached out and grabbed Iolvin by the arm. "No, wait." Pulling him so he faced her Ari asked, "Do you think I'm a pretty? Or am I just a whore?..."

Yoyo tried to look away, but Ari only squeezed his wrist tighter. He gave in and took a look like she requested, finally taking a moment to inspect her for the first time since they were kids. "Lulu, don't be silly. You're beautiful." Taking his paw and rubbing it through her hair he added, "And you'll never be a whore. You're too nice for that I think."

Pulling him in closer, Ari sat up and gave Yoyo a kiss. "Thank you, Yoyo."

Panicking from the sudden gesture, Iolvin pulled free and slipped out the door. "S-sorry, sis. Need to get to bed." He locked the door and shut it behind him, then fell onto his bed holding a paw to his muzzle. "She's just stressed is all... Yeah..."


Iolvin woke up at a motion in his bed, propping himself to look over his shoulder at the source. Ilaria had slipped into bed with him and cuddled against his back. It brought a smile to his face as he remembered the last time she did that, almost a decade ago. It was the night after she discovered her different physiology, scared to death what other people would think if they found out she wasn't fully female. She always trusted Yoyo more than anyone and she wasn't afraid to show it.

Yoyo's eyes bulged and he quickly rolled back to his original position on his side. An arm slipped over his chest and he squirmed when he confirmed his suspicion. It was dark so he wasn't sure at first, but feeling her against him proved that Ilaria was topless. Granted, he wasn't any better. He quickly remembered he slept in the nude himself and scooted his lower body forward. He didn't want to wake Ilaria up and have her find out, but Iolvin decided he should slip out of bed and put on some boxer briefs at the very least.

Ari slipped her paws down and grabbed dangerously close to Yoyo's groin, instinctively trying to use him as leverage and pull her own rump forward. Iolvin glided a paw of his own down to stop her, but froze when he realized there was something rubbing against his tail. When he came to the realization that the hard object wasn't her own tail, he jerked forward with a slight yip.

"Hmm?..." Ari mumbled just barely waking up. "What's up, Yoyo?"

"Uh..." Iolvin paused a second before giving a real response, noting Ilaria hadn't actually woken up quite yet. "Nothing. Go back to sleep," he whispered as she already began dozing off.

Only she didn't exactly go back into the deep sleep from which she awoke. Ari continued pulling herself closer until there wasn't any room for her cock between them. She rolled her hips a bit, eventually poking the appendage between Iolvin's thighs. He froze up immediately and hoped she'd move into a new position, but only found his breathing lose rhythm instead. Ari started pulling him by the hips and bucking herself between his thighs, as if making love to them. Iolvin stayed still and tried to be quiet, confused and unsure what he should do. By the time he settled on jumping from the bed, it was all over. Ilaria only took a few dozen seconds, but she started spurting cum all over the sheets and Yoyo's embarrassingly enlarging member. Ilaria just had a wet dream all over him.

"Shit," he whispered as he noticed how much of a mess there was. "Well what am I gonna--?"

"What're you hmm?" Ilaria softly spoke up, finally awake and with good reason. "You alright th-- Oh gods!"

As Ilaria puled her hips back and her cock free, Yoyo propped himself up again and said, "It's alright, sis. Just a strong dream. I get 'em myself." He grabbed his own cock and pulled it so it wouldn't tent the sheets then added, "It's nothing to be embarrassed about."

"B-but I..."

Sitting up on the edge of the bed Iolvin interrupted, "Sis, you couldn't control it. It's fine." He reached into his nightstand for a moment and pulled out a strip of condoms. Handing them to her, he told Ari, "Maybe try wearing one of these if you're ever worked up. You, uh... make quite a mess."

"Yeah, I... Thanks?" She looked at one of the condoms and then clarified, "Worked up though... but I don't do any of... that... so..."

"Wait, you don't even masturbate?" Laughing now, he went back to the nightstand and reached into the lower compartment. "No wonder you had a wet dream. You're all backed up if you don't pop one out every so often."

"Yoyo! Gross!" Ari rolled on her back in frustration and held the condoms up, still inspecting them. "Hey, why do you even have these? You don't have a gir--"

"None of your business, sis," Yoyo laughed out, tossing some things onto Ilaria. Spotting her still sporting quite the erection through the sheets, he pointed and added, "Here, these might help with that problem."

Ilaria looked at the items then to her hard-on he was smiling at and said, "Dumbass! Shit... Hey, what's this?"

"A fleshlight and some lube. Don't worry, I always used those condoms to keep from washing it too hard." Iolvin turned to face her better and forced himself to stop grinning. "Seriously, if you're not that good by yourself give it a try."

"But," Ilaria paused and opened the toy then continued, "how the fuck?... I appreciate the gesture, but I don't think I can--"

"You need to see how to use it?"

"WHAT?! NO!"

That grin stretching over his face again, Yoyo snatched the toy and lube and said, "Watch the voice, Lulu. And if you're fine with it, I can show you how it works. It's simple really." He popped the cap on the lube and started pouring the syrupy liquid into the opening of the toy. "You just use a lot of lube, and then..." He stuck two digits into the mouth of the toy and simulated finger fucking it. "...you just do what comes naturally. Get it?"

Ilaria blushed as her brother demonstrated how the fleshlight worked, partly at the lewd gesture he was making and partly as how she imagined the softness of the thing being around her. "Will it fit and all? I'm... well you know how big it is."

Yoyo flipped off the sheets over himself and said, "I'm not as big, but close enough. Twins, after all." After putting the toy next to his rod to show it could indeed accommodate all of him, he then passed it over. "You already screwed my legs. No shame in showing me if you get the concept here either."

Ilaria made a contemplative frown and then took the device. She slowly slid off her side of the sheets and exposed her guy bit to the cool air. Tentatively she prodded and played with the fleshlight with her paw, finding it much silkier and inviting than she originally thought. Then with a bit of hesitation she pressed it to the tip of her cock. She was just about to start pushing into the toy when Ari realized what Yoyo had said about keeping things cleaner with a condom. She put the toy in her lap for a second and ripped open one of the wrappers with her mouth. Iolvin chuckled as she tried to make sense of the thing and snatched it from her, slowly putting on her tip in the right direction. When she got the hint she rolled it down the rest of the way, her blushing only getting to bad you could see it through her fur. Then with the rubber surprisingly fitting her snugly to the base, Ari resumed her little trial.

Taking a moment to slip off her panties the girl asked , "So I just... push in on me?" She did just that, then softly squealed, "Ah, it's cold!"

"It has to warm up, silly." As another giggle escaped his muzzle, Yoyo reached over and put his paw over the top end to control it a bit. "You slide it on and off, however you like really. You just have to find your pace is all." Then he twisted the top cap a bit and loosened it. "And this controls how much suction it has. I'd try not too much at first."

"So, just up and down like this?" Ilaria very slowly started moving the toy, having to bite her lower lip in pleasure at even those small movements.

"Yeah, that's it," Iolvin confirmed in a soft, approving tone. "Just do it however you like best."

The two otters laid back together in a bit of awkward silence as a brother watched his sister pleasure herself. Ari seemed to be getting the hang of things rather quickly, though in all honesty it didn't take much to figure out what you liked in an intimate sense. Eventually the one having fun only led to complications for the other, Yoyo finding his paw guiding itself to his own groin. At first he just slid some fingers up from the base to the tip to clean bits of Ari's cum from his length, but eventually he just found himself compelled to grab the whole thing around and stroke it gently to the same rhythm as his sister.

"Hey... Hey! Yoyo!" Ilaria stopped her movement and sat up to look at him. "What are you...?"

"Ah, sorry. Sort of got myself worked up thinking about all this." He stopped himself and stood up, headed for the bathroom. "I'll just clean up the right way. Besides, looks like you've got the hang of that thing. You can finish if you like while I'm gone." He rounded the bed and paused to give Ilaria a kiss on the forehead. "And I'll forget any of this happened. Sort of a necessa--"

Ari pressed upward and kissed Yoyo on the lips softly. "You're too sweet to me, bro." She reached a paw to rest on his cock, testing the water so to speak. "But I'd like to help you with that since you helped me... Okay?"

Iolvin took a second to think about what was happening, what it meant. He slid back a step, then slipped into the bed next to Ilaria matter-of-factly stating, "Twins. You know what that means. We take care of each other, no frets and no regrets."

Ari slumped against her brother with a murr as she started her motions again. This time she started lifting and sliding a paw on each of the pair's lengths with a matching set of soft moans in the dark to complement. After a few minutes of awkwardly sitting still, Yoyo leaned back into his sister and glided a paw to one of her breasts. He kneaded and groped it just a bit, and when Ilaria didn't complain he began tracing a claw around the nipple. He ducked in for a quick suck, but everything just seemed odd from the position he was in so he pulled back.

"Lulu..." He reached out and took control of the fleshlight adding, "Flip around for me."

"Yeah..."

The otter girl did as she was requested, scooting around so her chest hovered near Yoyo's cock and vice versa. Yoyo then started pumping the toy firmer and faster than his sister was trying earlier, hunching his hips forward in sync. Ilaria took both her paws and rubbed his length between them, simply trying to emulate what was being done for her. She tried to keep it up, but found herself eventually facing her brother and bucking her hips into him like instinct told her. Then Yoyo had an idea.

"You got the lube?" Iolvin asked.

"Y-yeah... got i-it."

He smiled as he heard the pleasure in his twin's voice, then brought his groin closer to her chest. "Squeeze a little on your tits and hold 'em together, okay? It's alright if I fuck 'em right?"

"Uh... Yeah," Ilaria said as she rubbed some of the gel between her breasts. "C-can you hold t-that..."

"Yeah, pound away, sis," he interrupted as he got her drift.

Yoyo pinned the fleshlight against his chest so his sister could do about the same to him as he did to her. The two began thrusting their hips and gliding their cocks into each other's moist gaps, mutually bringing each other closer to their peaks. Yoyo got greedy though, the sight of his sister's dripping pussy only leading him to take a delectable sniff of her scent. He just couldn't help himself after that, driving his muzzle forward to lick and lap at her folds.

All but a few tender caresses and thrusts later and Ilaria suddenly lost control of her hips. Yoyo caught on and furiously attacked her from both fronts, moving the toy again as well as forcing his tongue deep into her pussy. Ari whined and let out a "Heeeeeee!..." as she finally came hard. She released a huge load, jet after jet, into the toy and condom. It was so much more than either expected that Yoyo took it upon himself to cease his pussy licking and instead lap up his sister's cum that was leaking out around the edge of the rubber.

"Fuck, sis!" Yoyo started rapid-thrusting into his sister's chest as she shook and quivered around him until he had no choice but to warn her, "I'm gonna cum!"

Realizing what a mess she made before, Ilaria assumed the worst and tried to point her brother's cock away from her. She couldn't quite get him clear of her tits fast enough though, Yoyo blasting them with his own cum a few times despite her efforts. She was still climaxing herself though and didn't know when to quit, quickly pulling back and taking her brother's tip into her muzzle. When all was said and done, Yoyo jerked himself free once he felt exactly what happened.

"Lulu, you didn't have to do that!" he stated as he started to sit up. Ilaria didn't quite hear him though, swallowing a bit of his cum before just passing out with a drooling smile. "You silly otter..." He flipped around so they were both laying feet towards the headboard and game her a cuddling hug, ignoring the extra warmth their various liquids added. "We'll just clean up in the morning, okay?" He slipped the toy and condom off his sister, noting the way the rubber was inflated perhaps too much before tying it off. "How much you got in there, anyway? Don't tell me you need to clean that much out the pipes every day."

Holding Ilaria tighter now and pulling the sheets over them, Iolvin mumbled, "Well, good night..." Dozing off himself he lovingly murmured, "I love you Lulu..."
