Everyone Experiments in College

Part 1: Love and Ice Cream

Isaac laughed at nothing in particular as he lay his head on Scott's shoulder. Everything was a little bit spinny, and a lot funny.

"You. Okay?" Scott asked, his words clear and coherent, if a bit slow. He placed his hand on Isaac's left thigh and gave it a gentle squeeze.

Isaac raised his head, grinning as the wobbly, happy feeling hit him again. He scrunched up his mouth as he answered. "Great!"

Stiles laughed from Issac's other side and waved his hands expansively. "He's grrrreeeeeaaaatttt!"

The three of them cracked up as Stiles collapsed across Isaac's and Scott's laps, making himself comfortable as Scott started stroking his hair and Isaac folded his hands on Stiles' stomach, thumbs languidly messaging him through his shirt.

"Fun night, guys?" Danny, their Uber driver, asked from the front of the car.

"Grrrreeeeeaaaatttt!" They all declared in unison before dissolving into another fit of laughter.

Isaac decided Stiles had the right idea as he collapsed against Scott's chest, his head now on Stiles' shoulder.

Scott let go of Stiles' head with one hand so that he could drape an arm around Isaac, holding them both at the same time.

"So, I have to ask, who's dating who?" Danny inquired, chuckling at their antics as he watched them in the rearview mirror.

"Oh we're all best best friends," Isaac answered, squeezing Stiles close with one hand and clumsily reaching back with the other to pat Scott's chest.

"And. Roommates," Scott added for emphasis. "And. And brothers."

"Not bioblogical blothers though," Stiles clarified before stage whispering to Danny, "I'm blisexual."

"Dude, you've got too many L's," Isaac told Stiles, sitting up a little bit and giving him an overly serious look.

"Whaz an elle?" Stiles asked, reaching up and rubbing Isaac's throat. He was warm. And pretty.

"An L," Issac answered, furrowing his brow. "You know, an L!"

Stiles shook his head. He didn't know.

Isaac huffed, exasperated. "Scott, tell him abou-about the L's"

Scott nodded, running a hand through Isaac's hair to let him know he was on the job. "Stiles. Stiles, listen."

Stiles' looked up, past Isaac, and into Scott's soft brown eyes. He was pretty too. Scott and Isaac should make out, Stiles decided. He'd like to see that.

"The L's are. Are in your. Your mouth," Scott told him.

"My mouth?!" Stiles asked, horrified.

The other two boys nodded jerkily.

Stiles giggled. "I want to get you in my mouth."

Scott gave him a confused look. "Which. One of, one of, of..."

"Of us!" Isaac interjected with a finger wave, proud of himself for helping Scott.

"Yeah. Of us. Are you talking to?" Scott asked.

"Indeed," Stiles answered, nodding meaningfully and tapping the back of Danny's seat like he was sharing an inside joke.

Scott chuckled and Isaac pulled Stiles closer against his body. Soon they were both snoring lightly, leaving Stiles the last one conscious in the car with Danny.

Stiles played with Isaac's fingers for a little while, but eventually grew bored and sat up.

"So you're not really brothers?" Danny asked for clarification, looking at Stiles in the rearview again.

Stiles shrugged at him before taking off his jacket and draping it over Isaac's chest. "We sorta are, just not bly blood. Me and Scott – always been blest fliends. But then when we were like flourteen my dad and his mom got mallied. So we're step blothers. Then the next year my dad, my dad...uh what was I slaying?"

"About Isaac joining your family," Danny prompted.

"Oh right. My dad answered this domestic displute case. Heza sheriff. Anyway, Isaac's old dad was..." Stiles frowned and gave Isaac's knee and shoulder a squeeze. "Anyway we adopted him and stuff. He's our adopted bro."

"It looks like you're all really close," Danny said, smiling at Stiles in the mirror.

"We are. Like sooo close. When we were kids, I useta be really jealous if other people played with Scott. But like, Isaac..." Stiles shook his head, smiling affectionately at his adopted brother. "It's okay for Isaac to play with Scott. 'Cause he's Isaac, you know."

Danny nodded. "Yeah I see."

"I just wish I could, you know, plaaaay with them," Stiles said, before leaning over and whispering to Danny too loudly for it to actually be a whisper. "I mean their penises."

"Yeah, I got that," Danny answered, fighting back a laugh.

"Do you think that's weird?" Stiles asked, eyebrows knitted together in worry.

"Nah, they're really hot, and you guys aren't biological brothers. It's fine."

Stiles nodded, agreeing with Danny's assessment. "Yeah, plus I just, like, love 'em so much, and I do suck a pletty mean dick if I do slay so myself. I wanna do that floor them."

"Have you offered?" Danny asked.

Stiles shook his head, accidentally banging it into the window in the process. "Nope. I didn't wanna make things weird. But me and Scott useta blow each other when we were younger. So I think he'd still want to."

"Are either of them gay or bi?" Danny asked.

Stiles shook his head again, this time eying the window suspiciously like it was going to attack him. "They're straight. But I don't wanna date them – that'd be weird – I just wanna mess around, have some fun, make 'em feel good. That typa thing."

Danny shrugged. "You should go for it. They seem like pretty open guys. I bet it's something you'd all enjoy."

Stiles nodded, losing himself in thought and eventually slumping down against Isaac and Scott again.

"I think this is your stop," Danny said a little while later as he pulled up in front of the address he'd been given.

Stiles grinned and reached into the front seat, wrapping his arms around Danny. "I like you."

"I like you too," Danny answered, patting Stiles' hands around his chest.

"Do you want my number?" Stiles asked.

Danny considered the question for a few moments, wondering if he wanted to get involved with Stiles and by extension this complicated but seemingly nice group of guys. Eventually he decided to go for it. "Yeah sure. Call it out and I'll text you."

Stiles gave Danny his number and they exchanged a few quick texts and talked about getting together and going out some time before Stiles woke his two non-biological brothers and wouldbe lovers.

"Are we. Here?" Scott asked, opening his eyes and blinking as he looked around.

"If we aren't here, where would we be?" Isaac asked, philosophically.

"But we are here," Stiles pointed out.

Isaac turned and leaned his forehead against Stiles'. "Exactly," he whispered, warm breath ghosting across Stiles' face.

He smelled like tequila shooters and Isaac, and Stiles liked both those things very much. He had to remind himself it wouldn't be okay to just lean in and kiss him. "I love you," he whispered instead, his mouth almost against Isaac's but not quite.

Isaac smiled a big goofy grin and wrapped his arms around Stiles. His face slid across Stiles' until he was whispering in his ear, "I love me too."

Stiles quirked an eyebrow and pulled back enough to look at Isaac. "You mean you love me or you love you?"

Isaac turned the question over in his head, trying to make sense of it before answering. "I love both of us. And Scott," he added, his head rolling back onto Scott's shoulder. "Ooh and ice cream."

"What?" Scott asked, catching just the tail end of that.

"I love you and ice cream," Isaac answered, grinning up at him.

Scott smiled back and carded his fingers through Isaac's hair again. "I love you and ice cream too."

"Do we have ice cream?" Isaac asked hopefully.

Scott stared off into the middle distance. "I dunno."

"You guys should probably go in and check," Danny said, chuckling and unlocking their doors.

Scott nodded. "That's a good idea." Then he leaned over and tried unsuccessfully to whisper to Stiles. "I like him. He's smart. Did you get. His number?"

"Uh huh. I put it in my phlone," Stiles answered, reaching backward and opening his door.

"That's a good place for it," Scott said, also opening his door and getting out.

"Wait, I'm stuck in here...and there's no ice cream anywhere," Isaac whined, falling over across the now empty back seat. Stiles grabbed his legs as Scott simultaneously grabbed his arms, each pulling in a different direction. Isaac chuckled. "This isn't going to work."

Eventually they got inside and collapsed in a heap on the couch, Scott mostly sitting on Stiles' lap and Isaac sprawling out in the other direction on the remaining two thirds.

"I thought the couch was bligger," Stiles remarked as he slid his hands under the front of Scott's shirt and started rubbing his abs.

Scott flinched and grabbed Stiles' hands through the material, holding them still. "Stiles! Cold fingers."

"I know, I'm warming them," Stiles answered with a giggle.

"See how you like it," Scott said with a devious grin before turning and grabbing for Stiles' stomach. The angle and his squirming made it impossible for Scott to get his hands under the front of Stiles' shirt so he settled for getting one hand on his hip and the other inside the back of his shirt.

"I do uh...actually like it," Stiles admitted, pressing his body back against the points of contact and staring intently at Scott's mouth.

Scott rolled his eyes but didn't move. Instead he leaned forward and pressed his forehead against Stiles'. He always got affectionate when he drank, and now that Stiles' hands had warmed up, he was enjoying the contact.

Isaac laughed from the foot of the couch. "You guys look like you're gonna make out."

Stiles turned and smirked at him. "Maybe we will. We have before."

Isaac folded his arms and scowled at them. He had heard the stories and it reminded him that Scott and Stiles had a special bond that he could never be a part of, that they'd had almost a decade of friendship together before he'd even met them.

"Are you feeling grossed out or left out?" Scott asked, letting go of Stiles' neck so he could rub Isaac's leg.

"The second one," Isaac mumbled quietly, looking away.

"Awww, Isaac!" Scott released Stiles and crawled along the couch until he was on top of Isaac's mostly recumbent body. "Do you wanna make out?"

Isaac looked up into Scott's face, trying to decide if he wanted to or not. He did sort of like the warm pressure of Scott's body pressed against his own and the thought of kissing Scott didn't seem intimidating or unpleasant, just a little weird and confusing. "I don't know. I'm kinda drunk. Can we have ice cream first, then decide?" he asked.

Scott grinned down at him and kissed his forehead instead of his mouth. "Good idea. Give us a chance to sober up."

Stiles inwardly groaned. For a second there he thought his desire to see Scott and Isaac sucking face had been about to come true. It hadn't happened, but he decided to focus on the positive: Scott seemed receptive and Isaac hadn't said no.

They ate their ice cream on the couch and caught up on a couple of TV shows they'd DVR-d earlier in the week, sobering up in the process. When the second episode ended Scott announced that he was going to take a shower and go to bed.

"But what about kissing?" Stiles complained, giving Scott his best pouty face.

"Good night!" Scott said with a chuckle as he kissed Stiles on the cheek. "And don't feel left out, dude," he teased, placing a second kiss on Isaac's cheek.

Isaac laughed and gave Scott a brief one-armed hug, but Stiles just frowned at him.

"Don't be mad, Stiles," Isaac said, bumping his leg against Stiles' after Scott had left and they were alone on the couch.

"I'm not mad. I'm just disappointed...and kinda horny."

Isaac hesitated, wanting to be sure he wasn't going to regret his suggestion. When he was sure he'd be okay with however this played out he said, "We can make out a little if you want."

Stiles gasped and paused the show they were watching. "Seriously?!"

"Yeah...I mean, if you want to."

Stiles scoffed. "If I want to? Dude, you're hot as fuck and one of my all time favorite people. Of course I want to."

Stiles put his arm around Isaac's back and pressed himself against Isaac's body as he leaned in for a kiss. Isaac had already closed his eyes when Stiles stopped, his lips poised over Isaac's. "Wait, you're sober enough to consent right? I'm not taking advantage of you or anything am I?"

Isaac reopened his eyes. He was startled to find Stiles so close but didn't move back. "No, I'm fine now. I barely feel tipsy anymore. Besides, everyone experiments in college right?"

"Well, that's the glorious rumor I've been waiting to substantiate," Stiles said with a shrug before closing the small space between them and sealing his mouth over Isaac's.

Isaac gasped and froze for a second, unsure what to do. Then he decided if he was going to experiment, he was going to do it right. Besides, it was kind of cool that he and Stiles were doing this and he didn't want to seem like a bad kisser, so he raised his hand to the back of Stiles' head and pulled him closer, simultaneously parting his lips and flicking his tongue over Stiles' lips, inviting him to take things up a notch if he wanted.

Stiles moaned into Isaac's mouth and tilted his head, deepening the kiss and pressing his tongue against Isaac's, and holy fuck his tongue was in Isaac's mouth! Isaac's gorgeous, sexy mouth – and wow, now he tasted like vanilla and Isaac, and Stiles was definitely still a huge fan of both.

Isaac didn't know what to do next. Stiles was moaning and trembling lightly against him, obviously way more into this than Isaac was. However, Isaac didn't want to stop and he wanted to give Stiles some encouragement so he grabbed Stiles' hand and pulled it into his lap. He wasn't hard, but he thought Stiles might enjoy feeling him up anyway.

Stiles broke the kiss in surprise, licking the roof of Isaac's mouth as he pulled away – and god he was going to burn that sensation into his brain. "Seriously? You're okay with this?" Stiles asked, gently rubbing Isaac's balls, his fucking balls, through his pants.

Isaac nodded. "Sure, I want you to have fun."

"Are you having fun?" Stiles asked, tone serious, because as much as he really wanted to keep going, there was no way he was going to let anything happen that Isaac might regret later.

"Yeah," Isaac decided, asking himself that same question. "Being kissed and having my crotch rubbed isn't exactly terrible."

Stiles licked his lips and tried to stay calm. "I-I could do better if you took your pants off."

Isaac pressed his lips against Stiles' in a brief kiss before pushing him back enough so that he could stand. "That makes sense."

Stiles' eyes widened in awe as Isaac unbuttoned his jeans and slid them off, revealing a pair of loose, but sleek, blue boxer briefs – and okay technically seeing Isaac lounging on the couch in his underwear wasn't exactly unprecedented, but the current context made tonight easily a hundred times sexier. "Thank you," he breathed with absolute appreciation.

Isaac laughed as he sat back down sideways on the couch, one leg tucked under him and the other hanging off the edge, his knee between Stiles'. Isaac grinned at him. "Wow, I've never once gotten a 'thank you' for taking my pants off before."

"Then you've been taking your pants off around idiots," Stiles told him.

"I've definitely taken my pants off around you before," Isaac pointed out.

"I rest my case," Stiles said, fisting the front of Isaac's shirt and yanking him back into the kiss. His heart was pounding in his chest as he tentatively reached into Isaac's lap with his other hand and started carefully messaging his soft, but hefty bulge.

Isaac moaned into Stiles' mouth as he felt himself swelling in Stiles' hand. It felt really good and there was something very exciting about doing this with Stiles. There was just one thing worrying Isaac. "This won't mess things up will it?" Isaac asked, breaking the kiss.

Stiles shrugged and stared lasciviously at the tent in Isaac's lap as he continued stroking it through the soft, thin cotton fabric. "It won't mess anything up as long as you take your underwear off first."

"What?"

"Yeah, it's fine. I'll catch it...or swallow it." Stiles winked at him. "I swallow by the way."

"I meant mess things up between us," Isaac clarified, trying to stay focused as Stiles' finger rubbed circles over the tip of his cock through his underwear.

"And by between us you don't mean the couch cushion?"

"Stiles," Isaac intoned in his best long-suffering voice. It was undermined a bit by the pleasured undertones thanks to the slow handjob Stiles was still giving him.

Stiles reluctantly stopped jerking Isaac off through his underwear and made eye contact. "I don't think it will. When me and Scott messed around it made us closer. But if you don't think you'll feel good about this later, you're right. We need to stop."

"I–I don't want to stop. I just...you and Scott got closer?"

Stiles smiled fondly. "Yep."

"Well...getting off and bonding even more in the process does sound like a pretty good deal." Isaac nodded, making his final decision. "Okay, take off your pants."

"Oh dude, no that's okay. You don't have to do anything to me, or even see me do anything to myself. Let's just focus on you and I'll handle myself later."

Isaac frowned and pushed Stiles' hand away as he reached for Isaac's lap. "I get that you're trying to be cool and make me comfortable, but frankly it's kind of offensive that you think I'd be that selfish, with anyone, but especially with you." Isaac cupped the side of Stiles' face and placed a chaste kiss on his lips. "If you're getting me off, I'm getting you off, and obviously this'll be my first time handling another guy's equipment, so by all means, give me pointers as we go."

"You are so awesome!" Stiles declared, giving Isaac a hug then a quick, sloppy kiss on the mouth, too eager to get out of his pants to be precise. "Boxers too or...?" Isaac nodded so Stiles hooked his thumb into both his pants and his underwear and slid them briskly down his legs. Unfortunately his feet got caught in the cuffs and the next thing he knew he'd toppled over backwards onto the couch, landing hard against the side of Isaac's body.

Isaac laughed and shoved playfully at Stiles. That had actually been perfect and had gone a long way toward diffusing some of Isaac's anxiety. This was Stiles, his klutzy adoptive brother and best friend (along with Scott). They could fuck each other's brains out and nothing would ever ruin that bond. It probably would make them closer.

"Here, let me," Isaac said, getting off the couch and grabbing one of Stiles' flailing legs. Once he had freed it from Stiles' pants, he grabbed Stiles' other leg and repeated the process.

Stiles sat still on the couch, legs spread so that Isaac could see everything, but not touching himself or doing anything that might make Isaac uncomfortable.

Isaac took him in slowly, resisting the instinct to look away. Isaac had seen Stiles and Scott naked lots of times, such as when they were changing for lacrosse, going swimming, or coming out of a shower. He had even seen them erect on numerous occasions when he had accidentally walked in on masturbation sessions or once when he came home early and found Scott having sex with his ex-girlfriend, Allison, on this very couch. However, all those other times he had just seen flashes of their equipment; it had always either been accidental or at least incidental. He had certainly never stopped and examined things before. Yet that's just what he was doing now and it was oddly exciting.

Isaac wasn't a dick expert, but he judged Stiles' to be about average in length, maybe slightly longer. He estimated it was about six-and-a-half to seven inches. It seemed a little bit less girthy than average but not significantly. It fit him well actually: longish and slightly slim, just like Stiles himself. He kept his pubes short and neatly trimmed and his balls shaved smooth, which Isaac had already known anyway from their basically boundary-less conversations. Stiles had low hanging balls, which Isaac had also known from conversation, just as he knew Stiles loved having those balls played with.

"Is this okay?" Stiles asked, glancing down at his erection self consciously. "I honestly don't mind putting my underwear back on if you want me to."

"Stop being an idiot," Isaac said as he rejoined Stiles on the couch and then leaned in for a kiss. As Isaac's tongue slid into Stiles' mouth his hand reached between Stiles' legs. He gently but firmly took hold of his nuts and began carefully rolling them around in his palm. They were hard yet pliant and very warm. Holding them gave Isaac an unexpected rush of power, even though he would never do anything Stiles didn't eagerly want.

Stiles yelped and thrust his shaft against Isaac's inner wrist. He moaned lewdly into Isaac's mouth and lightly nipped his bottom lip as the delicate rolling became a full-fledged massage. Meanwhile, Stiles' fingers had found their way back to Isaac's clothed dick. He jerked Isaac's shaft with one hand as he used the fingers of his other hand to tickle the underside of Isaac's cockhead.

Their bodies were pressed close together, so close that their arms and legs prevented Isaac from getting his other hand into Stiles' lap. He settled for fisting the short hair at the base of Stiles' skull and gently pulling, remembering another kink Stiles had shared over the years.

Stiles was panting as he broke the kiss several minutes later, lips tingling blissfully, but not nearly as blissfully as his balls. "Fuck man, you really know what I like."

Isaac laughed and gave Stiles' his biggest grin, remembering that his happy smile was another thing Stiles enjoyed. "You talk about sex a lot."

"Will you uhh..." Stiles eyed the wet spots in the front of Isaac's boxer briefs where he had gotten him leaking thanks to prolonged cock teasing.

"Oh yeah, of course," Isaac said before he lay back on the couch and arched his hips, hooking his thumbs into the waistband of his underwear and pulling them down.

Stiles licked his lips and swallowed hard. That was definitely a flash of Isaac's taint and asscrack he had just seen before he sat up again, and goddamn was Stiles ever going to try to burn that image into his retina. He was immediately distracted, however, as Isaac's exposed erection came into view.

"Holy fuck!" Stiles declared, gaping and staring openly at it.

"Wh–what is it?" Isaac asked, feeling self conscious with the way Stiles was looking at him. He didn't think he had anything to be embarrassed about and hoped that had been a good reaction, but either way it was disconcerting.

"Isaac, you seriously have the most beautiful cock I've ever seen in my life," Stiles said, looking away long enough to make eye contact as he said it.

"Oh come on, it's not that big," Isaac said, feeling himself blush from the attention. That's not to say he wasn't enjoying it immensely.

"It's not the size, I mean it is a great size – what is it, like eight inches?"

"Eight-and-a-half on a good day," Isaac answered proudly.

Stiles nodded. "Yeah, great size, but that's not what I mean. It's just fucking gorgeous. May I?" Stiles asked, desperate to touch it but wanting to make sure he had explicit permission first. When Isaac nodded he didn't waste any time gently wrapping his fingers around it.

Isaac moaned softly and bucked against Stiles' hand. It hadn't really been that long since someone had touched his cock – Isaac did pretty well with hookups even though he didn't have a regular girlfriend – but it seemed like an entirety nevertheless.

"Wow it even feels perfect. The curvature, the heft, thickness-to-length and cockhead-to-shaft ratios...Seriously man, I think your dick is like mathematically perfect. It's the Platonic Ideal of a cock." Stiles moved it around slowly and carefully, making sure to examine it from every wonderful angle.

"Damn, that's quite a line," Isaac answered, practically glowing with pride and confidence now.

"Not a line," Stiles insisted, shaking his head. "Perfect, perfect cock. Can I lick it?"

Isaac barked out a sharp laugh at the sudden requested. "Go for it."

Stiles moaned in anticipation and slid onto his belly on the couch, his legs hanging off the edge. He pressed his left hand firmly against Isaac's pelvis, enjoying his soft, warm bush. Isaac kept his pubes trimmed like Stiles, but they were longer. It made him seem neat and groomed yet still natural and masculine. His balls were smooth too, but the grooming stopped around the perimeter of his sack, which had thick tufts of light brown hair peeking from the sides. The effect made his balls and cock looked exquisitely nestled, showcased between his thick, muscular thighs, below his lean, sculpted stomach, and against a beautiful light brown backdrop of velvet.

Isaac resisted the urge to thrust and buck, or point out that Stiles had just promised him some cock licking. He knew Stiles basically had two modes: unable to focus or hyper-focused. It felt nice seeing that content, excited gleam in his eye as he explored Isaac's manhood. Isaac could be patient if Stiles was enjoying himself this much.

Stiles gripped the base of Isaac's shaft with his right hand and leaned in close, nose hovering over Isaac's balls as he enjoyed the raw, crispness of his adopted brother's pheromones. He reminded himself vigorously that Isaac was his adopted brother, that there was nothing wrong with his overwhelming desire to suck Isaac's balls and choke on their heavenly dense, purely sexual aroma.

Stiles didn't have permission to suck Isaac's balls, however, and he wasn't sure how he would feel about it. Stiles loved having his own balls sucked, but it was a love it or hate it type of thing, and he wouldn't risk doing something Isaac might hate. Then Stiles remembered that he did have permission to suck something else. His gaze snapped up to Isaac's long, thick shaft and he needily humped the sofa cushion as he raked his eyes along it before zeroing in on Isaac's cockhead. It was swollen and flushed pink, a perfectly proportioned mushroom cap with just the right flare and slope. Fucking hell! Isaac needs to become a cock model or something.

Isaac's cockslit glistened slightly in the light, calling Stiles' attention to a small droplet of precum beading on the tip. Without another thought Stiles plunged his tongue against it, lapping the treat off the end and then immediately wrapping his lips around Isaac's cockhead and vigorously tongue-flicking the sensitive underside.

Isaac gasped and gripped Stiles' head. For all of two seconds he struggled to hold still, then he remembered that Stiles liked to have his hair pulled and talked about how hot it was when guys got aggressive with him during a blow job. "If you don't like this please tell me," Isaac said in a shaky voice before pressing his blunt nails against Stiles' scalp and holding Stiles' head in place as he began thrusting into his mouth.

Stiles gagged and swallowed around Isaac's cock, whimpering and moaning as his eyes started watering and his own cock throbbed hard against the cushion. Unfortunately Isaac must have misinterpreted Stiles' reactions because he instantly stilled his hips and let go of Stiles' head. "Mmm Uhnn," Stiles hummed urgently against Isaac's erection, letting go with one hand and giving Isaac a thumbs up.

A wave of relief washed over Isaac. Not only hadn't he crossed a line he was getting the green light to keep going, which he immediately did, pistoning the blissfully hot, wet back of Stiles' throat with an abandon he had never allowed himself before. Stiles kept choking and gagging but also periodically flashing Isaac more thumbs up. A few minutes later, Isaac took off his shirt as he became overheated and Stiles immediately started cascading his hands up and down Isaac's chest and stomach as he deep-throated him.

"Whoa!" Scott exclaimed as he walked down the stairs and found Isaac pumping Stiles' mouth in a way he had only seen in porn before. It wasn't a complete surprise, however, considering he had only gotten out of bed because he had heard sex sounds coming from the living room and eventually decided fuck it he wanted in too.

"Oh my god!" Isaac shouted as he sat up, insistently pushing Stiles away from his crotch.

"Hey Scotty," Stiles croaked with a smile at his other best friend. His throat was sore in the best possible way and while he was definitely a hundred percent sober at this point, he was utterly drunk on lust. "Want a turn in my mouth?"

"Fuck yeah!" Scott answered, grinning as he peeled his shirt over his head and threw it on the ground, then stripped out of his pajamas pants.

"Alright!" Stiles fist pumped the air. Tonight was going so well!

"You, uh...what?" Isaac looked back and forth between them as Scott came and stood by the end of the couch. He knew they had blown each other before, but as far as he knew it had been years since it happened and he hadn't expected them to be this casual about it.

Scott shrugged and then gasped as Stiles unceremoniously swallowed his dick to the root. "You guys got me really worked up with all that moaning. Wait, you don't mind do you?"

Stiles pulled off of Scott's cock with a satisfyingly lewd pop and turned to Isaac. "Wait do you? Did you want this to just be us?"

"No?" Isaac answered, trying to make sense of his feelings. His no was automatic – he had always shared everything with Stiles and Scott, of course he didn't want to exclude Scott. Something felt unsettlingly different with Scott here, however.

"Aww dude, you're feeling left out again," Scott said as he recognized the same look on Isaac's face that he had seen earlier in the night when he and Stiles had almost made out.

"Oh," Isaac said as the pieces clicked into place. There was no use denying it so he just nodded.

A moment later Stiles had literally thrown himself on top of Isaac and Scott had wrapped his arms around Isaac and was cradling Isaac's face against his stomach. Isaac was surprisingly comfortable with the fact that Scott's wet erection was pressed against his shoulder. All that seemed to matter was the intensity with which they were hugging him and the speed at which they had done it.

"You know we don't love each other anymore than we love you, right?" Scott asked, fingers carding through Isaac's hair the way they had on the Uber ride home.

"Yeah man, you're our brother. Equally intense love here," Stiles answered, pulling back enough to look at Isaac then placing a chaste kiss on his lips.

Isaac laughed and felt a flush of embarrassment. "Maybe you shouldn't emphasize the brother part right now."

Stiles snickered. Isaac kind of had a point.

"Well we are brothers," Scott insisted. "Just without the genetics to make this creepy. Plus we were older when our families merged so" –Scott shrugged– "it should be fine."

"Okay, I guess you're right. Carry on sucking. I'll..." Isaac trailed off. What was he supposed to do? Watch and jerk off? That wouldn't work; he was getting off on experimenting but he didn't think he would get off on just watching. Should he leave and finish himself off? That seemed unsatisfying. Turn on the TV and kick back while he waited his turn? That would probably distract Stiles.

"I have an idea," Scott said, letting go of the others and turning to leave. "Let's go to my room."

Stiles shucked off his shirt, the last piece of clothing he was wearing, and raced up the stairs after Scott because one, Scott's idea obviously involved sex and was probably going to be awesome and two, Scott's ass. On the stairs. Naked and bouncing. Isaac probably wouldn't be able to properly appreciate that view anyway, so he could bring up the rear. Stiles snickered. Isaac could certainly bring up Stiles' rear if he wanted to. Good god, I hope he wants to!

Isaac wasn't sure if it was his imagination or not but Stiles seemed to be wiggling his hips more as he climbed the stairs in front of Isaac. Isaac curiously checked out Stiles' ass, trying to figure out if it did anything for him. It was smooth, which Isaac decided was a plus. Isaac had seen a line of black hair peeking out of Scott's crack as he turned to leave and his asscheeks had a smattering of dark hairs growing outward from that central line and upward slightly from the backs of his legs. Stiles on the other hand kept everything really smooth back there, which was what Isaac was used to from his past sexual experiences. Stiles' ass was shaped differently of course, more masculinely, but it was still a nice ass, and Isaac was incredibly horned up by this point from having just received the best blow job of his life but not getting to nut. If Stiles wanted to take their experimentation to the next level and let Isaac fuck him, well Isaac was more than willing. Fuck, I hope he wants to!

Scott could practically feel Stiles' eyes on his ass as he finished his ascent up the stairs and walked down the hall to his room. He had no doubt that Stiles wanted to fuck him and Scott wanted it just as bad. Scott was completely straight, but he was also completely into prostate stimulation. His ex-girlfriend Allison had used a strap-on on him almost as often as he had fucked her. Since they had broken up Scott had been getting very reacquainted with his dildos and butt plugs during solo play, but there really was no substitute for getting fucked by an actual person. He had almost broken down and asked Stiles to fuck him on more than one occasion over the last few months, but they hadn't messed around since they were horny teenagers and he hadn't been sure how Stiles would react until now. Damn, is he gonna give it to me good!

End Note: This part was basically all just set up. In the second and final parts they'll have lots of very explicit, very loving sex with each other. I'm going for an intense, porn with feelings type vibe. The with feelings part necessitated a longish setup with backstory and characterization, but the next parts will be pretty much all action and dialogue with the three of them just changing from one activity/position to the next.
