Everyone Experiments in College

Part 4: Happiness and Hormones

Isaac fluffed a pillow, folded his arms around it, and buried his face against it as he spread his knees on the bed, revealing his hole to someone for the first time. He felt a weird mix of vulnerable yet safe, self conscious yet sexy. He smiled against the pillow at Stiles' reaction a moment later.

"Fucking fuck fuck, man! Damn that's a fine ass," Stiles said, vigorously jerking his cock a few times as he looked at it. He whimpered and squeezed his balls as the act almost sent him over the edge. He could get off all day looking at Isaac's ass, but he desperately needed to fuck it, not just look at it.

Isaac's ass was round and muscular. Each cheek mounted majestically like a half globe, smooth and hard, spreading gracefully to reveal Isaac's inner treasures. The top of Isaac's asscrack near the base of his back was smooth and supple-looking; however, midway to his hole in the deepest valley of his crack a smattering of light brown hair appeared. The hair growth thickened slightly and spread to the walls of his asscheeks as it reached his hole. The growth then followed the grove of Isaac's ass down along the sides of his taint, leaving the taint itself with only a dark blond fuzz as the main trails of hair continued around the perimeter of his shaved-smooth balls. The black band of the cockring contrasted strikingly with Isaac's medium skin tone and highlighted the size and heft of his balls.

Isaac's asshole was the crowning glory, however. It was every bit as perfect and beautiful as Isaac's cock, a tight, narrow slot with a tract of soft-looking, slightly darker skin around it, hinting at the silky, smooth goodness that lay within. It was a paler, calmer pink than Scott's hole and didn't look nearly as needy; however, Stiles was resolved to change that.

Stiles knew he needed to get Isaac ready. He needed to lick or finger him, prep Isaac for his cock, but looking at Isaac's obscenely hot hole, Stiles' reaction was visceral. Preparations aside, he had to get his cock all over Isaac's hole and taint and the instinct was too strong to resist another moment. Stiles' scrambled forwarded on his knees, propping his legs between Isaac's as he vigorous tapped Isaac's hole with the tip of his cock, stoked his shaft up and down and back and forth in Isaac's plush valley as he massaged Isaac's swollen taint with his thumbs. Stiles slid his fingers under the black band binding Isaac's cock and balls, making Isaac whimper and moan as Stiles continued exploring Isaac's innermost external recesses with the sensitive glans of his penis.

Fuck, fuck, fuuuuck! This is so hot!

Stiles' whole body was trembling as he struggled to still his hips, fought the blinding urge to just keep thrusting against Isaac's crack until he spilled his cum all over the outside of Isaac's hole. Stiles didn't want that, or at least he didn't want that half as much as he wanted the alternative, half as much as he wanted to explore Isaac's internal recesses.

"I need to fuck you so bad," Stiles said, a desperate whine in his voice.

Isaac bucked back against him, ground the grove of his ass slow and hard along the full length of Stiles' steel-hard prick. Isaac's breath was ragged and his heart was pounding as he said, "Do it, Stiles, please do it!"

Stiles took a deep breath and in a burst of determination pried his manhood away from Isaac's ass. He could do this; he could wait just a little bit longer. He backed up and hunched over, then plunged his tongue against Isaac's opening, lapping at Isaac's tight, virgin slot as he squeezed and kneaded his asscheeks.

Isaac gasped and whimpered as he pressed back against him. Stiles' tongue was warm, wet, and possessive against his hole, licking it, sucking it, prodding it, then trailing up and down and back and forth along Isaac's crack, claiming and slicking every part of him. Then it was back to Isaac's hole for more prodding and lapping. It felt unbelievably kinky and intimate, but also just good, so fucking good.

Scott had gotten a look at Isaac's hole too. It was definitely a virginal hole and Scott found himself getting anxious. He trusted Stiles not to hurt Isaac, but protecting Isaac was second nature to Scott and he knew Stiles was amped up and beyond ready to go. Scott needed to make sure Isaac was safe, so he scooted off the bed and went to his nightstand. He perused his collection of toys, selecting the smallest butt plug he had, then a couple of medium and medium-to-large dildos, and finally a large dildo that was slightly bigger than Stiles. He put them all on the bed next to Stiles with an extra bottle of lube just in case.

Stiles took his mouth away from Isaac's hole and snickered as he looked at the toys Scott had spread out. "It's so obvious you were a boyscout when we were little, Scotty. You really take always being prepared to the next level."

Scott sniggered and rolled his eyes before climbing back on the bed, this time sitting next to Isaac and massaging his shoulders. "You doing okay? You know you don't have to do this if you don't want to."

Stiles' heart sank at the suggestion, but he didn't hesitate to add his agreement. His voice was muffled, his face once again pressed against Isaac's ass. "Oou reary ron't, ran." He pulled back, needing to make sure Isaac understood. "You really don't, man. I don't wanna do this unless you're completely sure it's what you want."

Isaac laughed and leaned into Scott as he simultaneously pushed back against the pad of the finger Stiles had just pressed against him. It still hadn't breached him, but he was tingling beneath it. "I'm sure. You both make it seem like getting fucked is incredible."

"It is!" Scott and Stiles agreed in unison.

"Then I want some too," Isaac answered, sure of his decision.

"It's not going to hurt at all, I promise. I'm going to do this right." Stiles squirted an ample amount of lube into his hand, took a moment to let it warm, then began slicking up Isaac's hole and his own finger.

Isaac hissed, momentarily overwhelmed as Stiles' digit finally penetrated him. It wasn't physically overwhelming or unpleasant, just a lot to get his head around. Stiles was inside of him, but soon Stiles would be inside of him. Soon Stiles would let go inside of him. Isaac was positive it was what he wanted, but he was nevertheless quivery with nerves and excitement.

"Come here," Scott said, hand on the back of Isaac's head as he gently massaged his scalp and the base of his skull. With his other hand Scott repositioned the pillow, gently easing it out from under Isaac's head and into his lap.

God, Isaac loved Scott so much in that moment, loved him for being so perfectly attentive and wonderful. Isaac hummed in relief as he collapsed into Scott's lap, letting the tension ease from his shoulders as he wrapped his arms loosely around Scott's waist and let Scott soothe him. He nuzzled the side of his face against the pillow as Scott caressed his cheek and rubbed his upper back.

A moment later, however, Stiles' finger, which had been cautiously easing into Isaac and gently stretching his ring of muscle, finally sank further in and–

"Aahh!" Isaac gasped and let out a low, deep moan, openly shivering as the sensation shot straight through his gut and directly inside his cock, making it throb and leak between his legs. "Oh f-fu-fuuucckk!"

"Yeah?" Scott asked knowingly, thumb stroking the apple of Isaac's cheek and fingertips caressing the soft skin under his jaw. He was so happy Isaac was feeling this and that he got to watch him discover those sensations.

Isaac nodded and whimpered again. Goddamn it feels good!

"Have you never played with your prostate before, Isaac?" Stiles asked, gently rubbing circles over the hot, pliant bundle of nerves. The sounds he was eliciting from Isaac made it hard to focus and – Fuck! Isaac sounded so good moaning like that, Stiles was worried just the sounds Isaac was making would get him off.

"No, I've never had anything in there before," Isaac answered brokenly, burrowing closer to Scott's stomach and tightening his arms around Scott's waist as he hung on for dear life. The tip of Isaac's nose was now pressed against the fuzzy hairs of Scott's treasure trail.

"I am so getting you an Aneros for Christmas," Scott told him.

"I am so gonna use it," Isaac answered, unsure what it even was, but if it was something that would mimic the feeling of Stiles' finger, then yeah, he really wanted one.

Lost in lust, Isaac tilted his chin and began mouthing at the long, thin hairs of Scott's lower abdomen, then swirling his tongue up over Scott's taut, shallow navel. When he realized what he was doing, he pulled his face away enough to say, "I dunno why I'm doing this."

Scott massaged his temple. "Don't over-think it, bro. Just keep doing it if you're having fun."

Isaac sighed and began lapping at the deep groves and hard bundles of muscles that formed Scott's lower abs. Yep, definitely fun.

By now, Stiles had graduated to fucking Isaac with the small butt plug, but he was starting to feel jealous. His cock was still throbbing with need and he didn't dare touch it, yet he need some sexual stimulation. His ass was still tingling from Scott fucking him. He was still wet with Scott's seed and it was slowly dribbling out of his hole and down his taint and balls as he hunched over on the bed, his own ass in the air as he worked Isaac over. He didn't want to lose anymore of Scott's cum and there was a simple way to kill two birds with one stone.

"Hey Scott, can you get another butt plug? For me," Stiles added, wanting to be sure Scott didn't pull out another starter model thinking it was for Isaac.

Scott chuckled and gently eased Isaac away from his lap, moving the pillow as he leaned over the side of his bed and rifled through his nightstand for a toy that would suit Stiles' needs. When he found one he tossed it to Stiles; however, before he could close the drawer Isaac also had a request.

"Maybe another cockring too?" Isaac said on hands and knees as he eyed Scott's re-exposed genitals. Scott's penis was soft, but it hung long and thick over his hefty balls, nestled erotically beneath his thick, bushy black pubes and the tuft of black hair peeking out from beneath his balls. Desire pooled even heavier in Isaac's gut. He had seen Scott's soft dick countless times over the years, but – Geez! Had it really always looked this good?

"You wanna put on another cockring?" Scott asked, tilting his head in confusion.

Stiles was confused too. He reached between Isaac's spread thighs and rubbed his sloppy, slick palm all over Isaac's completely rigid erection. Thanks to the cockring Isaac already had on, Stiles could even feel veins bulging on Isaac's shaft – which fuck! Stiles couldn't wait till Isaac rolled over so he could see all that bulging too. Damn, it was going to be fun fucking Isaac while he looked down and jerked that veiny beast.

Without preamble Stiles sat back on his ankles and rammed the butt plug Scott had just given him into his ass unlubed. Stiles' ass was still plenty slick with Scott's cum and the original round of lube, and the sudden ache and throb caused by the rough intrusion were very welcome just then, helping to take the edge off Stiles' intense need to cum while simultaneously satisfying some of his lust.

Isaac and Scott both looked at Stiles with concern as he yelped, but he just gave them a grinning nod and a thumbs up in response.

"I want you to put on a cockring," Isaac said, turning back to Scott. "I want to blow you some more. Your junk just looks" –Isaac bit his lip, openly staring– "so fucking amazing right now."

"Thanks man!" Scott said as he pulled his favorite cockring from his drawer.

"Wait, you don't mind do you?" Isaac asked, realizing that oh yeah, Scott also had a say in this.

Scott sighed dramatically. "Well, I guess I'll just have to suffer through another awesome blowjob if it makes you happy."

Isaac watched Scott put on his cockring with as much focused attention as he could manage now that Stiles had progressed to fucking him with a medium-sized dildo. The new cockring actually was a solid ring unlike the one Isaac was wearing that clasped together. Scott slid first one testicle into it, followed by the other, and then folded the end of his dick down, working it through the ring too. Wow, I'm really enjoying watching Scott touch himself.

Isaac gave Scott a needy look, which Scott readily understood. He reclaimed his spot at the head of the bed above Isaac, but this time didn't put the pillow back so that Isaac could rub his face all over Scott's rapidly swelling cock and pleasantly sensitive balls.

Once Scott was fully hard, Isaac swallowed as much of his shaft as he could take, ignoring the light gagging sensation as Scott petted the back of his head and told him how good it felt. Isaac agreed; there was something deeply satisfying about sucking Scott's cock while Stiles' fucked him, more vigorously now, with one of the bigger dildos.

Stiles took a shaky breath as he pulled out the second largest dildo Scott had given him from Isaac's hole, which wasn't a tight slot anymore. It was a beautifully puffy, glisteningly wet oval with rosy pink skin teasing the perimeter of a small dark opening. Fuck, it was hard for Stiles not to objectify it completely, not to rise up on his knees and shove his cock into it then and there.

It's not just a fuck hole. It's Isaac's fuck hole. Isaac. You love Isaac. You would never risk hurting Isaac. Calm down. Clam down.

Stiles picked up the final dildo, slightly thicker than his own girth. He lubed it generously and very gently eased it inside Isaac, watching in awe as Isaac's pinkish, fleshy muscle stretched around it, gripping it obscenely. He rocked it back and forth in a tight circle, focusing on easing the resistance. When Stiles was confident that Isaac would be able to take his cock without pain, even if Stiles' thrusts were clumsy and erratic – because let's face it, they were going to be at this point – he pulled the dildo back out, slathered more lube all over his fingers, and ran them around the pillowy, hot opening one more time.

Holy fuck, can my fingers have an orgasm?!

"Isaac, I-I think we're ready to go. Turnover please."

Isaac's throat tightened around Scott's cock. He tried to sort out his feelings as he slurped on Scott's erection one more time before pulling off and repositioning as Stiles had requested. Fear? Nope, not even a little. He felt ridiculously safe and at ease. Excitement? Hell yeah, so much excitement! He desperately wanted this. But also...

Isaac sighed and smiled, chest brimming with emotion as he look at Stiles, who was rubbing his thigh and grinning at him with unbridled enthusiasm, brown eyes sparkling and happy. Isaac usually loved Stiles in a comfortable, familiar way, a deep, quiet bond underpinning their day-to-day interactions, not tonight though; tonight Isaac loved Stiles in an intense, fluttery, oh-my-god-I-can't-believe-how-awesome-he-is! kind of way.

Isaac sat up and grabbed Stiles' wrists, gently pulling him forward until he could wrap him up in a hug, not minding at all when Stiles lost his balance and fell on top of him. He nuzzled his head against Stiles' then turned it and peppered Stiles' jaw and cheek with kisses.

Stiles giggled and held his face still, reveling under Isaac's affection. His hands stroked up and down Isaac's back before they trailed along the back of his neck and onto the sides of his face. He stared into Isaac's bright, unguarded blue eyes. "Yeah, this means pretty much everything to me." He looked over Isaac's shoulder at Scott. "You guys mean pretty much everything to me. Just so you know, this is the best night of my life."

Isaac surged forward, closing the small distance between their mouths as he captured Stiles' lips in a kiss.

A second later, Scott had pressed himself against Isaac's back and was clutching desperately at Stiles' shoulders.

When the embrace ended, Scott passed Stiles both pillows from the head of the bed. "Put these under Isaac's hips."

Scott spread his legs around Isaac and eased him backward until Isaac was reclining against his chest and Scott's chin was hooked over his shoulder. His arms were wrapped snuggly around Isaac's torso, thumbs massaging his pecs and abs.

Stiles heart raced as he eyed Isaac's spread open hole, flared and ready between taut, muscular thighs lined with a sparse dusting of brown hairs. Stiles could barely stand it as his gaze flicked up to Isaac's cock and balls, flushed a deep rosy pink and bulging beautifully. Isaac's engorged cockhead was darker than before thanks to the cockring. It was a needy purply pink and it glistened with precum.

Isaac took Stiles' hand by the wrist and placed on his equipment, encouraging Stiles to rub and fondle to his heart's content.

"Thank you," Stiles breathed more than said, palm slick with Isaac's juices as he polished his knob.

"Thank you." Isaac whimpered and moaned, lacing his fingers together with Scott's on his chest and stomach and snuggling back against him as fierce jolts of pleasure sparked through his body. God Isaac's life was awesome, held lovingly in one best friend and adoptive brother's embrace while the other lavished him with erotic attention.

"Do you want me to wear a condom?" Stiles asked, pulling his hand away and rubbing Isaac's precum on his own cockhead before also slicking up with more lube. "I'm prolly gonna cum in like two seconds when we start, so I don't think there'll be time to pull out."

"Don't pull out and don't wear a condom. Just–" Isaac gasped overcome with a heady cocktail of love and lust as he looked up at Stiles. "Uhnn, Stiles, I want you so much. Fill me up, with your cock, with your cum, everything."

Stiles trembled as he lined himself up with Isaac's hole, easing forward until Isaac's hot, wet ring of plush muscle connected with the over-sensitized tip of his dick.

"Ohh FUUUCK!" Stiles eyes widened as he felt his balls drawing up in his sack and his cock quaked with even more tingly energy. Stiles was wrong – two seconds had been a generous estimate. He was cumming now and he had literally just given Isaac the tip.

"I can't– it's, it's now! it's NOW!" Stiles grabbed Isaac's hips and winched him down onto his cock as he simultaneously lurched forward, slamming into Isaac and bottoming out as he was swallowed up in a full-body orgasm. "Ohh, Uhhn, UHNN!"

Stiles closed his eyes and collapsed against Isaac. He wanted to keep thrusting but it was too intense. It felt like his whole body had been turned into a giant throbbing nerve. Stiles couldn't breathe and his heart was pounding so hard Isaac must have felt it against his chest. With his last remaining breath, Stiles panted, "It's so good! It's s-sooo g-goodd!"

"Keep cumming, Stiles! Keep cumming!" Isaac urged, legs wrapped tightly around Stiles' waist, and hand palming the small of his back. "Unload as much as you can."

Stiles whimpered and did as he was told, flexing his pelvic muscles and trying to make his last few shots harder and fuller as he sprayed Isaac's inner walls.

It wasn't until several minutes later when Stiles had finally regained his senses and tried to sit up that he even realized Isaac's and Scott's arms were both wrapped around his back and his head was cradled between theirs on Isaac's shoulder. They were whispering sweet words to him that made his chest swell and had him deciding to stay put for a few more minutes after all.

"That was so good," Isaac said when at last Stiles had pulled back and sat up, though he was still buried to the hilt inside Isaac.

Stiles laughed and he felt his already hot, sweaty cheeks getting warmer. "Yeah, I'm sure that one whole thrust I managed was awesome for you."

Isaac cleared his throat and gave his waist a pointed look. His cockhead and shaft, along with the back of Scott's hand where it was pressed against Isaac's abdomen, glistened in the light, soaked with his precum. "I almost came. As soon as I felt you filling me I..." Isaac trembled and sighed, then rubbed Stiles' shoulders. "It was perfect."

It felt amazing hearing how into it Isaac was and how much he wanted Stiles, but Stiles couldn't help looking at Isaac's wet, throbbing cock and feeling disappointed in himself. "Man, if I coulda just lasted longer though."

"Dude!" Scott shoved at his shoulder. "You lasted longer than either of us. You've been having sex all night."

"And uh...if you want" –Isaac raised his eyebrows and shrugged, a grin lighting his face– "I'm certainly not asking you to stop now."

"Oh!" That should have been the obvious solution. Stiles moaned softly as he pulled back and rolled in again, shivering as his cum slicked his erection and squished satisfyingly inside of Isaac.

Isaac sighed contentedly and lay back in Scott's arm, resisting the urge to touch himself. He wanted to focus on his ass instead, on the needy tingle that made his whole body go slack and the blood rush to his groin.

"You want a cockring too?" Scott offered Stiles.

Stiles scoffed as he ran his eyes up and down Isaac's sweaty, lean body; his handsome, chiseled features; and his slick, pornographic nether regions. "Have you seen Isaac? I'm definitely not gonna have a problem keeping it up."

"Yeah, Isaac's beautiful," Scott said sweetly, nuzzling his nose against Isaac's neck.

Isaac giggled and felt himself blushing. He started to protest the compliments but changed his mind, deciding to return them instead.

"You're both so hot," Isaac said, voice straining as Stiles' gentle thrusts became more aggressive and the needy tingle in Isaac's ass became a consuming desperation. "I can't believe how turned on I am. How much I like your bodies."

Isaac gripped Scott's bicep, kneading the thick cords of muscle as he writhed backward against his warm, hard chest. Scott was so strong, so muscular and Isaac liked it on a very primal level, on a level that had nothing to do with feeling safe and loved in his brother's arm and had everything to do with those arms themselves.

Isaac's eyes tracked over Stiles' long, lithe torso, paying particular attention to the straining, flexing muscles in his stomach, the graceful sloping planes of his chest, the pert brown nubs of his nipples. Isaac concentrated on the way Stiles' cock made him feel, not the emotional aspect of connecting with Stiles like this, or even the physical pleasure that came along with the stimulation, but on the erotic thrill itself.

"I'm not straight," Isaac mumbled to himself as the pieces clicked into place.

Stiles' hips jerked and he stuttered to a stop inside Isaac on his next forward thrust. "What?"

"I'm not straight," Isaac repeated, grinning now as he realized the exciting implications that came with his discovery, the reality that his dating and sex pool had just doubled. "I'm bisexual!"

"Are you sure?" Scott asked, squeezing Isaac closer. "'Cause getting fucked just feels really good. I think most guys open to it would like having their prostates stimulated, regardless of sexuality."

"Yeah definitely," Isaac agreed, arching his hips and grinding down against Stiles' erection. "But it's not just that it's..." Isaac shrugged. "I just know now."

"Dude, this is awesome!" Stiles said. He tilted forward and gave Isaac a sloppy kiss, then rabbited his hips a few times, making Isaac moan against his mouth. "Welcome to the team."

"So awesome!" Scott leaned in, his face gently pressing against Stiles' face too as he kissed the corner of Isaac's mouth.

"Anything else you wanna try while you've got two guys to play with?" Stiles asked, partly teasing, partly hopeful.

"Actually yes!" Isaac declared. "I want to fuck and get fucked like Scott did."

"Oh you're gonna love that!" Scott said, his cock and ass throbbing as he thought about how hard it had made him cum.

Scott eased Isaac back on the bed as he shifted from behind him. He lubed up Isaac's straining, veiny erection then slicked two fingers and slid them into his own well fucked hole. "Which way do you want me?" Scott asked, straddling Isaac's waist facing him but ready to turn around if requested.

"Like this," Isaac said, eyeing Scott's cock again, then stomach, then his chest, then – yeah, like this!

Stiles raised his hands from Isaac's hips to Scott's chest as Scott impaled himself on Isaac's erection with one hard, confident bounce.

"Oh. My. God." Scott closed his eyes and let his head fall back against Stiles' shoulder as he rode the waves of sensation erupting in his ass. He ground his hips in slow, satisfying rolls, clenching his muscles around Isaac's dick every time another spark ignited against his prostate.

"Jesus, Scott! You're so loose and slippery yet...so fucking tight!" Isaac exclaimed as Scott's ass once again took him from a lazy, wet wonderland to a firm, gripping heaven. Isaac thought he was going to pass out from sensory overload when Stiles moaned and started bucking harder into Isaac.

"My ass is so happy right now," Scott said. He was grinning so hard his face hurt.

"Let's make your cock happy too," Stiles whispered into Scott's ear as his hand slid down from Scott's chest to his shaft and he began jerking him off.

"Aww, fuck." Scott reached over his shoulder and palmed the back of Stiles' neck, eager to reward him with a kiss.

"You like the way this looks, Isaac?" Stiles asked, making eye contact with him before looking away and surrendering to the kiss with Scott.

Isaac drew in a sharp, gasping breath and let it out as a moan, his eyes raking up and down the scene in front of him: Stiles and Scott locked in a sloppy, heated make out session, Scott's sweaty, muscular body writhing back against Stiles' chest and onto Isaac's cock, Scott's big, swollen dick in Stiles' hand, Stiles' thumb teasing Scott's glans as he jerked him briskly – it was the hottest thing Isaac had ever seen, and to top it off his whole crotch was burning with pleasure as he watched.

Several minutes later Stiles cleared his throat. "And switch!"

"What?"

"Huh?"

"Come on guys – ADD. I wanna try somethin' new." Stiles licked his lips and grinned as he realized what. "Isaac hasn't fucked me yet."

"That does sound really appealing," Isaac said, thinking back to the way Stiles' ass had looked as he had climbed the stairs in front of Isaac earlier in the night. There was something else he wanted to try too. Isaac's hand trailed up Scott's thigh and over Stiles' hand on Scott's cock. "And Scott hasn't fucked me."

They separated and repositioned on the bed. Stiles got on his hands and knees in front of Isaac and raised his ass in the air. As Isaac reached past him for the bottle of lube, Stiles grabbed his hand. "No more lube. I still feel full of Scott's cum. It's enough, use that. Fill me up with a second load, Isaac. I wanna drip with both of you."

Isaac trembled as he pulled the butt plug out of Stiles' ass. Fuck, Stiles looked incredible like this. His hole gaped and flared slightly from having been fucked by Scott's thick cock and then held open by the substantial sex toy. The smooth skin around his hole was a slick, shiny red and plunging his cock into it felt like the most natural thing Isaac had ever done. Isaac felt Scott's hot, creamy cum coat his shaft and the knowledge that he was inside the most intimate part of Stiles' body and slicked with the most intimate of Scott's fluids made Isaac's cock throb and his chest tighten.

Scott on the other hand, reminded himself that Isaac had been an anal virgin less than a half hour ago and that his cock was going to be the thickest thing Isaac had ever taken. He reached for the second bottle of lube and slathered his erection generously and likewise slicked Isaac's ass as he gently fingered him some more.

"I'm ready, Scott. I just want you inside me. Please!" Isaac whined and took shallow thrusts inside Stiles as he impaled himself on Scott's finger.

"Okay, just tell me if it hurts," Scott said, pulling his fingers away and tapping Isaac's hole with his glans before cautiously pushing the tip in.

Isaac moaned and bit his lip as Scott slid in further. Goddamn Scott was thick! Isaac felt a burn that hadn't been present when Stiles had penetrated him. Yet Isaac moaned harder and collapsed against Stiles' back as he realized that in this context...he liked it. He liked it a lot. He could feel Scott sliding into him inch-by-inch and it was unbelievably satisfying.

"Isaac, you feel really tight. Are you sure you're okay?" Scott tried and failed to keep his tone neutral, tried to hide how much pleasure Isaac's hot, tight ass was giving him. He didn't want Isaac to endure it for his sake if it did hurt.

"I am so fuckin' okay," Isaac mumbled, snapping his hips hard against Stiles' ass then rolled back the rest of way on Scott's dick, impaling himself to the hilt. The sensations shot up his spine and made the tips of his fingers tingly.

"Okay, just remember we can stop as soon as you want."

"I don't wanna stop till you cum in me like Stiles did and till I shoot in him."

Stiles moaned and braced himself for that long, blissful ride. "Sounds like a good stopping place to me."

Isaac laughed and set a slow, steady pace, bottoming out hard inside Stiles with every in thrust and grinding back flush against Scott's pelvis with every out thrust. Scott's arms were around his chest again and his hands were on Stiles' shoulders, pulling him back as he pumped in. Scott likewise met his back thrusts with quivering, seeking gyrations of his own.

"Harder, please Isaac! Harder!" Stiles pleaded as his temperature rose, not just in his ass but his whole body. Sweat dripped down his back and tricked in hot rivulets down his thighs, adding to the tickling need he felt consuming him.

Isaac grunted and slid one hand from Stiles' shoulders to the back of his head, fisting a wet clump of hair and yanking his head back as he remembered Stiles' hair pulling fetish.

Stiles yelped and let out a low, guttural moan. "Fuck yeah! Ha-harder. Harder."

Isaac tightened his grip in Stiles' hair and snapped his hips more urgently with every thrust.

"Harder here too," Scott pleaded, letting go of Isaac's chest and leaning back with his torso to give Isaac more room to buck between them. Isaac's silky heat had gone from good wrapped around his cock to fucking unreal. Scott could feel his balls drawing up against the band of the cockring, fighting to get in place and unload but being held back deliciously. The delay would make Scott cum harder, but he needed Isaac to take him there. If he tried to thrust too far into Isaac he would restrict his movements and break the heavenly rhythm they had going.

Isaac gritted his teeth and impaled himself hard against Scott. His vision blurred and he felt like he was going to split open as the aftershocks of Scott's steel-hard dick crashed against his inexperienced prostate and reverberated through his whole body. The burn had become a blissful, pulsing inferno, and it was just as hot on his cock, despite the slippery, wet piece of heaven he was sheathed in.

"Harder, Isaac," Stiles moaned brokenly.

"Harder, Isaac," Scott begged, just as desperately.

Their needy pleas tugged at his chest, had him bucking back and forth between them with reckless abandon, frantic to satisfy them both and also to relieve the blazing snarl of urgency in his own groin.

"Harder Isaac!" They chanted in unison. "Harder!"

As Isaac rabbited between them, his sense of distinction between his ass and his cock blurred until it was gone, until he was nothing but a white heat from the waist down. They were lighting him on fire from both ends and Isaac was as desperate to quell the flames as they were.

Scott couldn't take it anymore. His balls clenched and his cock quivered violently within Isaac's tight hole. Then he was flying over the edge, slamming into Isaac's ass hard and fast and yanking his hips back in a death grip. He didn't want to stop Isaac from fucking Stiles, from fucking himself, but he couldn't help it. Scott's cock had shattered into a million orgasmic pieces and it felt too good not to pump every single one of them into Isaac as deeply as he could.

"Aaah!" Isaac screamed as Scott arrested his forward momentum and winched him back hard, pounding against his prostate a beat too soon and breaking the rhythm in the best possible way. Isaac split open as Scott blasted him full of cum, finally quenching the fire and melting him into a heap of throbbing, tingly goodness. Isaac in turn yanked Stiles' head back and locked his other hand around Stiles' waist, holding him in place as gave Stiles the second load he had been begging for.

Stiles was denied his own release as Isaac's erratic final thrust missed its mark and left Stiles tangled in a knot of frustration as Isaac seeded him. As he dutifully clenched his ass around Isaac and encouraged both boys to get off hard, he realized he didn't mind that he hadn't cum yet. He had both their loads now, just as Isaac had his and Scott's, but Scott was still missing one. Stiles was glad he hadn't spilled it against the sheets.

As soon as Isaac's grip loosened, Stiles pulled away and scrambled to the rear of the bed. "Your ass in mine, Scott!"

Scott giggled and panted, head still spinning as he rolled off of Isaac and onto his back. He raised his hips and spread his legs in the air. "Take it!"

"Uhhnn!" Stiles pounded in hard and fast, hammering Scott's loose, well-fucked hole with a single minded focus. Nothing mattered but untangling his frustration, relieving himself inside Scott. "Fuck fuck fuck fuck fuck, I need to cum!"

"Do it, Stiles, cum for me!" Scott chanted, grateful for Isaac's soothing touches as Stiles pounded him.

"Mmmm, oh here I go!" Stiles buried himself as the tangled knot finally unraveled and he erupted in his second, even more powerful orgasm of the evening, shaking and cursing against Scott's body as Scott's strong thighs held him snuggly in place.

"There you go, Stiles, there you go," Isaac whispered, leaning over Scott and pressing his forward against Stiles'.

After everyone had caught his breath and Isaac and Scott had taken off their cockrings, Scott wrapped an arm around each of his friends and laughed as he surveyed the wreckage of his bed. "I'm gonna need to sleep with one of you guys tonight."

Isaac nuzzled under Scott's arm and reached across his lap to take Stiles' hand. "Or maybe both of us?" he asked hopefully, still craving the closeness.

"Yeah." Stiles squeezed Isaac's hand and placed a soft kiss on Scott's lips. "Let's go shower, then we can all sleep in my bed tonight."

They all started talking at once as they got off Scott's bed.

"So this was great!"

"I had a lot of fun tonight!"

"I love you guys so much!"

They laughed and exchanged hugs and chaste kisses before heading down the hall to the bathroom and cramming themselves into the shower. It was almost impossible to move and they had to wash each other by necessity due to the restricted space. No one minded, however, and mid-way through things devolved into an all out wet, naked, vertical cuddle session.

Once they were done they piled into Stiles' bed with Stiles claiming the middle position and the other two wrapping themselves around him.

"So when you come out to Mom and Dad about being bi...maybe don't mention exactly how you figured it out?" Stiles said to Isaac.

"Oh really? I was going to lead with the 'while I was fucking my brothers' part of the story," Isaac answered, smirking at him.

Scott shrugged. "They may not care. We're adults and we're not biologically related."

Stiles and Isaac exchanged a look and burst out laughing.

"Not everyone's as sexually evolved as you are, Scotty," Stiles said, rubbing his side. "There are some things people should keep to themselves."

"Oh, you're one to talk," Isaac remarked.

"What's that supposed to mean?"

"It means if you were a super hero, you'd be Super Over-share Man."

"Would not!" Stiles answered, sticking his tongue out, because Stiles was a paragon of maturity.

"Would too!" Isaac and Scott countered in unison before launching a coordinated tickle attack on Stiles.

By the time they were done wrestling and play-fighting, Stiles' bed was almost as wrecked as Scott's.

"So," Stiles said, still trying to catch his breath, as he looked between them mischievously, "race you guys to Isaac's room?"

Scott and Isaac looked at each other and shrugged, letting Stiles dash out of the room without them and 'win.'

"You know, I think I want ice cream," Isaac remarked. "Do we have anymore ice cream?"

"I dunno," Scott answered, sliding off the bed. "We should probably go check."

End Note: I hope you guys enjoyed the final chapter of this smut series. Oh and guess what? This wasn't just a college AU without supernatural elements, it was also an AU where no STDs exist. We don't live in that world so play safe, get tested regularly, and make informed decisions.

Also, if you liked this smut series, keep an eye out for a possible new one I'm considering writing called "The Invention of Sex" in which Isaac and Scott live in a world where sex, sexuality, and physical attraction have never existed, yet they find themselves inexplicably feeling it for each other and have to work out the mechanics of how to have sex without any frame of reference. It'll be a smut/humor combo with plenty of quirky, absurdity. It's very loosely based on the premise of the movie "The Invention of Lying" but obviously with sex instead of lying being the thing.

I'm also considering an Isaac/Ethan/Aiden AU threesome story (ideally only one part, but that's what I planned for this fic, so who knows?) called "Two for the Price of One" in which Isaac picks up Ethan at a bar, only Aiden's over-protective and worried about his brother hooking up with a stranger...so he just has to join in to keep an eye on things ;-)

Just tentative plans though, I may not do either story. In the meantime, please consider checking out my main Teen Wolf serial, "Iron Claws and Fragile Hearts" for a more plot-heavy romance story featuring an Isaac/Stiles & Isaac/Ethan love triangle set against a backdrop of supernatural danger.
