Big Brother

Chapter 3: Playback

Summary:

Scott and Stiles used the tablet to change Derek's body before they play around with him again.

Notes:

Ah-ha! We've reached the end of this story! This is the final chapter for the "Big Brother" M.O.R.P.H story, although I fully intend to create more fanfics utilizing this whole "M.O.R.P.H" master-tech tablet idea. Those fics will exist in a different universe though.

Anyways, I hope you enjoy the final chapter. I was surprised with myself for being able to finish this in a reasonable time-frame. I kinda of just got struck with inspiration and started writing. And it has a few more thousand words that I had initially planned.

Enjoy! :)

(See the end of the chapter for more notes.)

Chapter Text

With Derek innocently taking a second shower across the hall, ridding his beautiful body of everything it had endured not more than a few moments prior, Stiles and Scott were spending their time clicking through M.O.R.P.H’s interface, figuring out what else they could do to make Derek a better slut. And to nobody’s surprise, M.O.R.P.H allowed for a lot of creative freedom in almost every conceivable way possible.

The BODY tab on the tablet brought up a 3D hologram of a generic male body. It was nothing more than a grid-patterned man, which spun around on the screen in a very slow, pre-set animation. There was nothing inherently special about the hologram— it didn’t have any particular features to show that it was meant to represent Derek Hale, but that was fine, because the main purpose of it being so...bland, was to show that Derek was a blank slate.

On the right-hand side of the glowing grid hologram were tons and tons of new fashioned sliders— all of which were marked as Derek’s “preset” body attributes. But as with anything else the tablet’s technology provided, there wasn’t anything that both Scott and Stiles wouldn’t be able to change about Derek’s body. If they wanted him taller, they could do that. If they wanted to lighten his hair or eyes, it could also be done. But those were just some of the innocent changeable features. 

“Dominance….Submissiveness….Tit Plumpness….,” Stiles casually read through some of the more appealing preset slider options. “—ooh, we’ll have to do something with those.”

There were so many different options to toy around with. Truly, it was a buffet of sin. And the best part was that there wasn’t any limit as to how many different things about Derek’s body that could be changed around. Much like all of the other available tabs that the tablet’s interface had to offer, Derek was putty in the hands of his little brother and his little bro’s devious best friend. 

As Scott and Stiles flipped through the available pages of BODY sliders, Stiles called out when he saw something that he thought should be modified. The first thing that they did was take Derek’s initial “dominance” levels from where the slider was placed at a LEVEL EIGHT and slid it down to an absolute ZERO. Derek didn’t need to be dominant—not with how Scott and Stiles planned to use him. 

Similarly, they adjusted Derek’s “submissiveness” levels from the low preset level of TWO—maxing it out completely with a LEVEL TEN. That was more the speed Derek needed to be at. And considering how good and obedient he had previously been whilst getting his pretty mouth fucked, Stiles and Scott could only imagine how much more slutty Derek would be with a newly modified level of submissiveness. 

“Ooh, this one’s my favorite. I do it every time I’m in the mood.” Scott called out, smirking over to where Stiles remained at his side—intently looking down to the tablet’s sliders. 

Scott thumbed over to the slider option that read: “Hole Slick”, and double-clicked onto the attribute. Immediately, a tiny informational window popped up onto the screen, explaining what the attribute meant and what moving around the sliders would mean in regards to Derek’s body. And seeing as how Stiles was new to the whole thing, it gave him the ability to learn a little bit about how good M.O.R.P.H really was. 

“Hole Slickness—manipulates the body of the selected male physique, allowing for natural lubrication production.” Stiles read aloud in a studious, monotonous voice, thumbing dramatically at his chin. “ So —wait what?”

“He’ll get wet for us.” Scott snorted, turning to meet the otherwise awestruck expression on Stiles’ face. “We won’t even need to use lube.”

Stiles let out a loud laugh, grabbing the tablet out of Scott’s hand. “ Holy —I don’t even know why I’m fucking surprised. This tablet is a damn godsend. It just replenished our balls, of course it can make Derek get nice and wet for taking a couple cocks up his fat ass.”

Without hesitation and without any further word from Scott, Stiles clicked out of the informational window and modified Derek’s “Hole Slickness” levels— taking him from a starter position of LEVEL ZERO to TEN. Stiles’ own hard cock twitched with excitement as he handed the tablet back over to Scott to continue making the changes he wanted to do.

After a few more minutes and a handful of updated sliders, Scott shifted focus onto the 3D hologram model that spun around on the tablet’s screen. He double-clicked onto the male form and watched as the hologram blinked a couple times, before opening up in a whole different window of its own. From there, Scott began to click onto different body parts. 

Scott first clicked onto the hologram’s chest and used his index and thumb fingers to spread the holographic chest wider— signifying the desire to plump up Derek’s already muscular chest. Next, he spread the hologram’s thighs to be a tad bit thicker, followed by back muscle manipulation, bicep increase, ab tightening, and finally—a slightly bigger backside for Derek was in order. 

Derek’s ass was already perfect. It was huge, barely fit into the jeans that he wore on the daily. But Scott knew the power that the tablet held and there was no reason not to give Derek a fatter ass. After all, Derek, himself, wouldn’t care to notice. Once all of the new changes were finalized, Derek would just think as if his body was as it always was. But for Scott and Stiles, they’d have a grander time squeezing and slapping and fucking hard into Derek’s fatter ass, watching it ripple with waves from their thrusts. 

“Looks—about right, I think.” Scott muttered, glancing through the sliders’ changes before handing the tablet over to Stiles. “Care to do the final honors?”

Stiles smirked and swiped the tablet out of Scott’s hands again, this time clicking onto the FINALIZE CHANGES button that was situated as a pop-up on the tablet’s screen. There was a brief vibration from the tablet and then the screen refreshed, showing all of the new changes that had been made to Derek’s body. The new muscle mass, the submissiveness, the hole slickness, everything. 

The familiar sound of the bathroom shower shutting off caught both Stiles and Scott’s attention. Round two had officially begun. It wouldn’t take long for Derek to proudly find his way back to the bedroom, still under the effects of the tablet’s power, not even bothering with a towel wrapped around his waist this time. Instead, he’d step into the room with a bunch of new changes reprogrammed into his head and body. 

When Derek stepped back into the bedroom, Scott and Stiles couldn’t help but smile as their eyes raked across every inch of Derek’s wet, naked skin. The physical changes that the two had made with the 3D hologram function were incredibly obvious, but not obscenely off-putting. He looked the same, all except for a few tweaks here-and-there to make him even more perfect. 

Derek’s already toned abs were even more toned, tighter, and leaner. Stiles thought that if he were to run his hands across the insane ridges of muscle, he’d end up cutting himself. Not only that, but Derek’s chest was different—bigger, beefier, juicier. His tits wobbled with the casual gait of his steps as Derek came to stand in the middle of the bedroom. The same could be said for Derek’s ass, which was even thicker and begged even harder to be bred deep. 

Stiles let out an exhaled whistle, impressed with the tablet’s work. He circled where Derek was standing in the middle of the room, dripping wet with shower water, waiting expectantly to be told what he was supposed to do. That was the newly reprogrammed submissiveness talking. And neither Stiles and Scott could hold back their excitement at how much more malleable Derek had become with the click of a few buttons. 

“Somebody’s gonna get fucked brainless.” Stiles chimed in a sing-song type of voice. He took his place behind Derek’s solid form, craning his face closer inward so that he could nibble at Derek’s earlobe. He wrapped his arms around Derek’s body, bringing his hands up Derek’s frontside to cup at Derek’s beefier tits. 

Stiles! ” Derek shouted out in a breathless pant.

“Ooh, I think your big bro likes it.” Stiles laughed, squeezing and rubbing at Derek’s oversensitive nipples, staring over Derek’s shoulder to where Scott was standing with his big dick in his own hand. “Why don’t you tell Scotty what it is that you like, hmm?”

Derek gulped. “Touching—the touching, squeezing…”

Mmmhhmhelikesitwhen I play with him right here .” Stiles mumbled, almost unintelligible, as he nibbled playfully at Derek’s ear— feeling Derek’s body shiver under his touch. 

Scott snickered, swooping forward— pressing his own naked body up against Derek’s. Their individual hardened cocks speared against one another, mixing their body heat. Derek’s eyes seemed to go just as glossy and unfocused as they had previously. And Scott liked the look of it. He liked knowing how deep Derek was lost under the spell of the tablet. 

“And he likes it when I touch him here .” Scott added seductively, reaching down to wrap his fingers around Derek’s fat cock. He gave him a couple solid tugs and then began to stroke Derek’s cock slowly, lazily even, feeling Derek’s hot precum ooze against his knuckles. 

“Do you?” Stiles rasped into Derek’s ear. “Do you like when Scotty touches you there?”

“Y—yes.”

“Though so.” Stiles said smugly. “But what about here ?”

Stiles quickly dove two of his fingers into Derek’s wet hole, pressing past the tightness, pushing into the heat. Derek groaned out loudly. His eyes flickered alpha red. His knees buckled from the sensation and he nearly fell down to the ground, barely able to keep himself standing tall by himself. Luckily, Scott was there to help him. 

Scott clicked his tongue and cooed softly, letting go of where he was stroking Derek’s dick. He brought both of his hands up, scooping them underneath Derek’s armpits, using his strength to keep Derek from falling down to his knees. The man’s legs were jelly and all from a little bit of prostate stimulation. 

“No, no—we already had you on your knees, Der.” Scott said soothingly, staring deep into Derek’s unfocused, flared eyes. “Stand up.”

“I think I struck a nerve.” Stiles laughed, trading snickered coughs of breath with Scott. Stiles turned his attention back onto Derek. “What’s a matter, Derek? Never been touched back here, hmm? I didn’t think so. Girls don’t play around back here. But we do.”

Stiles’ fingers were long and slender. He had fingered himself from time-to-time and knew damn well that he was more than capable of bringing a man down to their knees, sobbing out pleas of mercy from the pleasure he could bring with just a couple of his fingers. So it was no surprise that Derek quickly became a quivering, antsy mess within a few minutes of getting fingerfucked.

Stiles drove both his index and middle finger into Derek’s tightness, starting off with a simple—yet punishing rhythm. But he quickly picked up the pace, much to Derek’s clear-as-day excitement. Stiles rapidly fucked his fingers into Derek’s wetness, harder and harder, pushing as deep as he could, curling his fingers every now and then. And when he did, Derek’s knees buckled. Prostate stimulation was the man’s “kill switch”. 

Scott was busy kissing and sucking at Derek’s sensitive nipples, biting softly at their hardness and pulling at the skin just enough until Derek wailed out a pleasured howl. Meanwhile, Stiles inserted a third finger into Derek, fingerfucking him even harder than before, curling his fingers with every insertion, fingering around to stab into Derek’s magic button. And sure enough, he found it rather easily. 

“Ah—ah, fuck!” Derek screamed. 

Derek came undone, hard and fast. His body seized and his already tight hole clenched down ever harder around Stiles’ slender digits. His fat cock spurted quickly against where it was pressed tightly against Scott’s hot body, painting the boy’s brown skin with sharp cuts of searing white. And as it oozed down Scott’s abdomen, Stiles refused to lighten up on the prostate massaging. 

“Gotcha.” Stiles snorted. 

“Fuck—I’m the one that’s gonna need a fucking shower.” Scott said, pulling away from where he had been sucking and biting at Derek’s plump tits. His own lean abs were oozing with Derek’s load, dripping down to the carpet.

Stiles withdrew his fingers from Derek’s hole, drinking in the noticeable sound of a wet squelch. The “Hole Slick” slider really did work. Whoever created the tablet and the software was some sort of sick genius—but Stiles wanted to blow them for giving him the chance to play around with Scott’s hot brother. 

“He came so hard—and I was only up to three fingers.” Stiles noted. “I don’t even know whether or not to chalk up that orgasm to him rarely getting fingered, or because we maxed out his Prostate Sensitivity.”

Scott shrugged, letting Derek toppling down to the ground. “I don’t know. Both, maybe.”

Stiles stepped over Derek’s collapsed body, grabbing onto Scott’s shoulders with a wide, excited grin spread across his face. “Imagine how fucking hard he’s gonna blow when he rides our cocks.”

“I know how hard he blows when he rides my cock.” Scott admitted proudly. “But I wonder what’ll happen when he takes both of us.”

“Let’s save that for the finale.” Stiles said, patting Scott on the arm as he walked over to Scott’s bed. He took a seat, but then immediately popped back up. “No—wait, let’s fuck him in his bed.”

“Fuck yeah.” Scott cheered. He reached down and picked Derek up by the arms, getting the great lug of muscle to stand again on his own two feet, despite still reeling from a brutal orgasm. “That way, he’ll get to smell everything we did when he finally conks out for the night.”

“How’s that sound, Der?” Stiles asked cockily, walking over to where both Scott and Derek were standing at the edge of Derek’s bed. 

Derek’s side of the shared bedroom was considerably neater than the tornado devastation that was Scott’s side. Nothing was out of its proper place. There were no scattered clothes on the ground. No sports equipment. No crumbled papers. Even the sheets and pillows on Derek’s bed were dressed up and unblemished by wrinkles. To the total stranger, one would probably think that Derek was some sort of ex-military dude. 

Stiles shoved hard against Derek’s broad chest, forcing the man to topple backwards onto the cushion of his bed. Derek’s legs almost instinctively spread open—thick, hairy thighs on lewd display. To nobody’s surprise, Derek’s fat cock was also hard again, dripping with precum. His body had already been torn down to the studs with an orgasm and yet there he was, ready for more. 

Stiles’ eagerness fueled him. He immediately tried to sweep his way in-between Derek’s spread thighs, cock in hand, ready to thrust hard into Derek’s tight, virginal heat. But Scott grabbed onto the slender human’s waist and tossed him back out of the way—stopping him dead in his tracks, much to Stiles’ displeasure. 

“Yo, what the fuck?” Stiles barked, rubbing where Scott’s warm hands had squeezed against his waist. “You gonna let me fuck our toy or not?”

Scott dropped down to his knees in-between Derek’s spread thighs. He hooked his hands underneath the bend of Derek’s knees and spread the man’s thighs and legs even more than they already were— lifting them up into the air with ease, thanks to his werewolf strength. Derek’s legs were thick and heavy, but not heavy enough to stop Scott from getting what he wanted. 

“No—wait a minute.” Scott said, looking up to where Stiles was standing—dejectedly. “I wanna eat him out for a little bit. I’ll give you a turn. Promise.” He smirked. 

Stiles rolled his eyes with a scoff, but he wasn’t nearly as miffed as he might have looked. He understood Scott’s desire. With somebody as hot as Derek all spread out before them, how could somebody not take the opportunity to rim the everloving fuck out of Derek’s tight hole? So while Scott dove down in-between Derek’s thighs, Stiles jumped up onto the mattress and knee-crawled closer to Derek’s face, leaning down to take Derek’s lips in a savage kiss. 

Derek seemed surprised at the kiss, almost as if it had taken his breath away, but that fact alone only enticed Stiles even more. He liked being able to surprise a werewolf. Stiles and Derek’s lips clashed together powerfully, yet incredibly sloppy—filled with all kinds of untoward sounds that escaped out in-between their draws of new breath. But they continued on. 

“Ever been kissed like this, Der?” Stiles slurred arrogantly, biting teasingly at Derek’s bottom lip. He took Derek in for another demanding kiss, swirling their tongues together, before pulling away to let Derek respond. 

But there wasn’t much of a solid response. Derek just kind of mumbled out something that sounded close to “not really” before nodding the best that he could manage. It was clear that his head was all kinds of fucked up from the tag-team. Scott was doing a good number on his hole, so much so that Derek’s legs were practically vibrating and his hips were involuntarily gyrating. 

Scott had rimmed Derek numerous times before, not that Derek remembered after it was all said and done. But nonetheless, each time felt just as powerful as the first. For Derek, after always getting mindwiped post ‘tablet time’, it was the first time ever getting rimmed— which manifested in the older wolf’s inability to control the way his body quivered with pleasure. 

For Scott, rimming Derek also always felt like it was the first time all over again. It was just that good. Goosebumps flashed across Scott’s tanned skin the moment that his tongue made cruel contact with the sensitive skin of Derek’s tightness and Derek’s body always shivered hard. Every groan, moan, and bitten off, panted word fueled the intimate passion of Scott’s work. 

Scott was merciless with it. He broke Derek down with the precision of his tongue like it was nothing. He made it seem easy with the way that he dug in to Derek’s wetness and swirled the tip of his tongue around, only to follow with the stiff drag of his own wet tongue up Derek’s hole, right up to the man’s ball, and then back down again. It was like punishment for Derek, but one that he would never want to break away from. 

Scotty— ” Derek groaned breathlessly.

Stiles pulled away from kissing Derek with a satisfied huff of breath. “Is he good? Is he giving you what you need?”

Derek’s eyes just fluttered into the back of his head. It seemed as though he couldn’t get any real words out of his mouth. As Scott’s tongue lashed around his tight hole, Derek’s own tongue was tied from the overstimulation. But it was fine, because Stiles was right there to push things along—push things in the direction that they needed to go. 

“Tell him, Derek.” Stiles urged, trading glances from Derek’s reddened lips, down to where Scott’s moppy head of hair was bobbing around with smooth glides as he passionately ate away at Derek’s wet virginity. “C’mon, take your hand, slip your fingers into Scotty’s hair, softly—guide him around, make sure he’s doing it right .” 

Stiles took hold of one of Derek’s slack hands and lifted it up, carrying it over so that Derek’s open palm could softly splay across the top of Scott’s head. There was something hot about giving Derek control, even though he was powerless in the situation. He didn’t have control. Stiles and Scott held it. But watching Derek chase it for himself was so fucking hot. It made Stiles’ cock throb against where it was pressed against Derek’s bare hip. 

Derek tugged slightly at Scott’s dark hair, guiding the boy’s head around—but he was completely lost as to what he was really supposed to do. He had never had somebody eat him out before. He had never felt so good from just somebody’s tongue washing over his own hole. At least— that’s what he thought. Little did he know that Scott had lapped around his body many, many times before. 

Eventually, Scott figured that it was time to switch things up. He didn’t really know how much time had passed, seeing as how he had gotten lost in Derek’s taste. Still—it had probably been a substantial chunk of time, and even though Derek wasn’t getting bored with it— he was still shaking where he was laid out—Stiles was more than likely going to want a turn with Derek soon enough. 

Scott pulled his face out from in-between Derek’s spread thighs. He looked a beautifully disheveled mess. His hair was all tousled from Derek’s lame steering work. At the same time, Scott’s mouth and crooked chin were dripping with Derek’s slick. He licked at his lips and then wiped them across his forearm, clicking his tongue to catch Stiles’ attention. 

“Well, he’s all nice and even wetter for us now.” Scott said, winking. He softly slapped his palm down to Derek’s hole, thumbing at where Derek was now even more sensitive than he had been. 

“It’s about fucking time.” Stiles cheered, popping up and off of Derek’s mattress. “You don’t even know how horned up I am for this, man.”

“Uh—yeah, I can fucking see it.” Scott laughed, gesturing down to where Stiles’ fat cock bobbed around in the air as Stiles stood up from the bed. 

Stiles made a show of cockily grabbing onto the base of his dick, jokingly swinging it around in Scott’s direction. He laughed and then slamming his hands down onto Scott’s sturdy shoulders, watching expectantly as Derek sat up from where he had been laid back. Derek’s dick was still raging hard and the glimmer of slick in-between his legs was more enticing than ever. 

Scott stood up from where he had been previously knelt down on the carpeted floor in-between Derek’s legs. He stood up to stand shoulder-to-shoulder with Stiles. Together, the two both looked down at where Derek remained on his own bed. There was an unmistakable twinkle of gleeful desperation in Derek’s bright green eyes. But he didn’t say anything. 

Derek just sat there on the cushion of his mattress, staring up to where Stiles and Scott towered above him. He kept biting on his bottom lip, almost as if he didn’t really know what he wanted to say. His thighs were still spread nice and wide, and he could feel his hole flutter involuntarily, eager to be touched. His gaze kept automatically flickering over to where Stiles’ long fingers were delicately fiddling around. 

“Oooh, seems like big bro sees something he’s interested in.” Stiles said cockily, bumping up against Scott’s shoulder. He held up one of his hands and cockily waggled his fingers.

“I think he wants you to fingerfuck him again.” Scott chuckled.

“Look— I’ll do you one better.” Stiles said, gazing down to Derek. “Finger yourself for us. We want to watch. And when you’re right there—body all hot and tense—about to cum again, I’ll give you something better than a couple fingers.”

Derek nodded. There was a lost, feral kind of smirk spread across his face. His tanned skin glowed in the soft bedroom lighting, now entirely dry from shower water. Derek’s lips were still red and sloppy from being mashed up against Stiles’ for an amount of time that Derek could barely even remember. All he knew was that he had been in heaven with Stiles on his lips and Scott rimming his needy hole. 

Tentatively, Derek slid one of his hands down— underneath his balls and hardened cock, right down to where he was hot and dripping with slick. He prodded the tips of two of his fingers into his tightness, shuddering under the touch. And then without having to be told what more he was supposed to do, without being able to bear his own anticipation, Derek shot two of his fingers deeper into himself. 

Derek felt his fingertips sink into his heat and then pushed deeper, past his knuckles. All was lost. A half-broken sob of pleasure slipped out from Derek’s abused mouth. It was almost as if his hand took on its own form of control. His thick fingers, usually accustomed to wrapping around a football or video game controller, were now pounding into his own hole. And he couldn’t stop himself. He didn’t want to stop himself. 

His fingers chased his heat. As Derek fingerfucked himself harder and rougher, his eyes became increasingly unfocused and hazy. He tried to maintain eye contact with both Scott and Stiles, but his vision continued to fade in-and-out of focus. His head pounded and swirled with desire and he could hear his own thoughts ordering him around, “more, more, more, fuck yourself, fuck your sloppy hole, please them—please Scott, please your brother, please his friend, you’re theirs.”

“He’s—he’s never done that before.” Scott panted, languidly stroking his own cock. 

Stiles was stroking himself with one hand and pinching at his pierced nipple with his other hand. “Done what? Fucked himself on his fingers?”

“Not that hard—not that eagerly. Not even with the programming I’ve done before.”

“Face it, your big brother’s a total fucking slut.” Stiles laughed, prompting Scott to do the same. They both stared on as Derek’s fingers fucked rapidly into his wetness. “Maybe you finally broke him.”

Scott scoffed, thumbing at the head of his own leaking cockhead. His toes curled. “Ha—yeah, right. I mean, you don’t think that could happen do you? Our mom would freak.”

“Uh—yeah, Mom, I kinda broke your eldest son by mindfucking him and turning him into my own personal cumdump. Now he won’t stop fingering his pussy and slobbing on my knob.” Stiles mocked jokingly, pretending to be Scott.

Scott laughed. “No, for real.”

“I don’t know.” Stiles said, shrugging. “Did the tablet come with any kind of instructions or warnings about using it too much on tragically heterosexual older siblings?”

“No.”

“Well, then he’s probably fine.” Stiles reached forward and lovingly pat Derek on the side of his stubbled face, caressing it softly. “I mean, would it even be that bad if he did stay like this? Just imagine it, Scotty. Snap your fingers anytime of the day and you’d have this pretty little mouth gagging on your cock.”

“The fucking dream.”

Stiles snorted. “Yeah, just make him clean himself up before your guys’ mom or his girlfriend come around—cause being drenched in cum is a conversation Derek probably doesn’t want to have anytime soon.”

Ten minutes passed and Derek was still working his fingers into the squelch of his hole as hard as he could manage. His thighs were properly soaked and his legs were quivering even harder than they had been when Scott had been down on his knees, driving his tongue into Derek’s heat. All the while, Scott and Stiles were still watching Derek tear himself apart, all whilst entertaining themselves by trading handjobs. 

Stiles and Scott’s cocks felt somewhat familiar in one another’s hands. It was like they were both operating on each other’s wavelengths, tuning in to just how they each wanted to be touched. Scott was a lot softer with his touch, but each stroke was precise and punishing. Stiles, however, was a lot wilder. He was quicker and rougher. He liked to spit down onto where his fingers were laced around the meat of Scott’s juicy cock. Scott liked it too. 

“Oh—oh god, fuck, Sc—Scott.” Derek managed out in-between tough breaths. He gasped, refusing to let up on the speed of his fingerfucking, and then came again—splashing up onto his massive tits. 

Derek didn’t even bother grabbing onto his own cock. Instead, his hips involuntarily stuttered up into the open air and his dick visibly throbbed as it blasted ropes of white up to stain the wobble of his plumped up tits. Derek’s body vibrated. His tousled hair shook with the movement of him refusing to let up on fingering himself. He looked so hot, so messy, so dazed, but so sloppy and so ready for more. 

Scott relinquished his grip around Stiles’ cock and surged forward over to where Derek was still clumsily working through the brutality of his own orgasm. Scott leaned in and swallowed down some of Derek’s moans with a passionate kiss. He cradled the back of Derek’s head, slipping his hands into the soft strands of Derek’s fresh hair, and kissed unapologetically hard. 

“Come on—” Scott said, breaking away from Derek’s lips. He looked over to where Stiles was standing expectantly, thoroughly pleased with the display. “—sit down on the bed. I’ll lift him up and set him down in your lap.”

“Fuck yeah.” Stiles said, claiming a seat next to where Derek was already sitting. He looked over to Derek’s debauched face, catching the gleam of excitement in Derek’s eyes. “You want that, Derek? You want Scotty to throw you down onto my fat cock?”

“God, yeah.” Derek said breathlessly. He wiggled around where he was sitting. “Fuck me.”

“You heard the slut, bro.” Stiles clapped his hands together. “He wants that tight fuckhole filled.”

With ease, Scott picked Derek up into the strength of his own arms. His biceps bulged as he did it. To outsiders, the very thought of somebody like Scott trying to lift the entirety of Derek’s weight was impossible. But one of the great benefits of being a werewolf meant that Scott could bend steel with his bare hands. So lifting up Derek and all of his beautiful muscle was a piece of cake. 

Scott side-stepped, carrying Derek in his arms, and centered them both in front of where Stiles was sitting in wait on the mattress. And then, with a slow and delicate motion, Scott began to lower Derek down onto Stiles’ lap. At the same time, Stiles held his own cock firmly in his hand and kept careful guide of it, lining it up directly with where Derek’s slick hole was about to press down. 

Derek moaned loudly, throwing his head back with pleasure, as Scott slowly sunk him down onto Stiles’ girth. And just as soon as he was fully seated down onto Stiles’ eight and a half inches, Derek immediately started moving. It was like something fired off inside of his brain. New switches were flipped. His body and his mind jumped at the chance to get fucked. 

“Ah, FUCK!” Stiles cried out, clasping both of his hands at the sides of Derek’s waist. He helped guide the rhythm as Derek began to bounce up and down on his cock, keeping the wolf centered and properly filled at all times.

“That’s definitely the ‘sloppy bottom cockslut’ mental trait we programmed into his brain.” Scott noted enthusiastically, watching as the beef of Derek’s chest bounced with each and every downthrust. “He’s fucking starved for it, dude!”

Shit— does he ride you like this? He’s amazing. Fuck, he’s so fucking tight. And so fucking wet.” Stiles groaned, gripping tighter into Derek’s sides. 

Even though Stiles wasn’t strong enough to physically lift Derek into his arms and slide him entirely up and off his cock, he was able to command the brutality of his own thrusts— which is exactly what he did. As Derek bounced down, spearing himself on Stiles’ length, Stiles snapped his hips upward to meet Derek’s ass. And from the sound of Derek’s pitched cries and moans, Stiles was definitely making contact with Derek’s amped up Prostate Sensitivity. 

Derek fucked himself on Stiles’ cock like he couldn’t get enough of it. He bounced around with a maddened pace, letting his tight heat take Stiles down to the root each and every time. Derek couldn’t bear to not slam down so hard. He chased the feeling of Stiles’ hips and thighs crashing upward to smack hard against his own thighs. Derek couldn’t be lazy. He could feel an offshore tide of shame just waiting to wash over him if he stopped himself from riding Stiles. 

Derek’s inner walls screamed with pleasure as he clenched down onto Stiles’ girth. He felt so empty when Stiles wasn’t entirely shoved up into him. And as Derek continue to fuck himself open, his body shook violently with an unbelievable feverish shiver that managed to claw its way through his veins in unexpected intervals. But every time that it did, Derek’s hard cock spurt out a stream of precum that splashed onto where Scott was standing in front of him. 

“Ooh, dirty, dirty Derek.” Stiles chuckled softly, grabbing into Derek’s hair—pulling at it just rough enough to force Derek’s head to lull backwards. Stiles kissed Derek's neck. “You like that, don’t you? Can’t get enough of it. You’re just not yourself when you don’t have a fat fucking cock stuffed in your fat ass.”

“Don’t stop.” Derek mumbled, grinding down hard on where he was split open on Stiles’ dick.

“We don’t plan on it.” Stiles slurred arrogantly, catching the sinister gleam in Scott’s eyes. 

Derek’s rhythm never once faltered. He continued to bounce up and down on Stiles’ cock, unable to stop himself. His gorgeous muscle was dewey with fresh sweat that poured down the beef of his tits in sweet droplets, coursing down through the ridges of his abs, right down to the non-stop bobble of his hard cock. His breathing was also heavier, slightly raspy and desperate, but he was fine. He was a werewolf. He’d manage. 

“Fuck—my turn.” Scott shouted, grabbing Derek up and off of Stiles’ lap. “Sorry, dude. I can’t— fuck —I’m so fucking hard.”

“Don’t sweat it, Scotty.” Stiles said, grabbing hold of his slicked-up cock as Derek was lifted off of him. He stood up. “Fuck him. Fuck him good.”

Scott quickly positioned Derek onto his back, slotting himself in-between Derek’s thick, hairy legs. He hoisted Derek’s legs up into the air and let them rest on the broadness of his shoulders and then took his meaty cock into the grip of his own hand. Scott swirled the head of his leaking cock up against Derek’s hole, which had already tightened itself back up following its stretch from Stiles’ girth. And then without as much as a quick exhale of breath, Scott shoved in.

Derek gasped and bit down onto his bottom lip, but Scott’s rapid speed was so quick and rough that he couldn’t even keep his mouth closed. It was knocked open, completely slack, as if screaming silently out to the void as Scott pounded into his body. A particularly harsh thrust knocked a tear out from the corner of Derek’s eyes. It ran down the side of Derek’s face, staining the heat of his skin. But all Derek could do was swallow down a sob. 

Stiles stood on the sidelines and watched, just as Scott had done before. He watched from an angle, allowing him to see Derek’s body get pitched forward under Scott’s thrusts, as well as watch the way Scott’s body moved in time with the rhythm that he decided to go with. And fuck— it was so fucking hot. Stiles felt his balls tingle at the sight alone. 

Scott panted out each time that he drove his cock into Derek’s body. His messy hair flopped around in sync with his wild movement. Sweat, which had been beaded across the tanned skin of his forehead, dripped down to splat against Derek’s hairy chest, which was already soaked and matted down. All the while, Scott kept his hands locked onto the sharpness of Derek’s hip bones to keep the man centered and well within his own grasp.

From where Stiles remained, fervorously jerking himself off, he watched as Scott’s lean back muscles rippled. He watched Scott’s tattooed bicep flex to an insane amount that made him look absolutely massive and powerful. But the best part was the way that Scott’s tanned, plump ass wobbled every time that he thrust forward. Stiles couldn’t even break away from staring. It was begging to be slapped, just as much as Derek’s. 

“Unnf, fuck yeah, Scotty!” Stiles snarled, landing a particularly harsh slap against one of Scott’s tight cheeks. He came up to stand directly alongside where Scott was bent forward, encapsulating Derek’s muscular form. “Jesus fuck, dude. He’s fucking crying at how good you’re giving it to him.”

Scott bit back a half-delirious laugh and then reached up, pulling Stiles’ face downward to lock lips. They kissed for a moment, so hard that their lips burned and that their teeth gnashed against one another’s. But as their tastes swirled, their heads launched up into the clouds— fluttering down only when they finally pulled away from each other with satisfied smirks. 

“So fucking hot.” Scott mumbled, looking back down to where Derek had a fucked out, glazed over look in his teary eyes. 

“Somebody’s lost, hmmm.” Stiles laughed, patting at the side of Derek’s face. “How’s Scotty doing, Derek? Is he giving it to you nice and hard and rough? You like getting slapped around and hammered into like a little slut, don’t you?”

“YES!” Derek cried hysterically. 

Derek wrapped his arms around the back of Scott’s neck, desperately trying to figure out how to bring Scott closer into his own body. It worked. He pulled Scott downward into a brief kiss and a nearly inescapable hold. At the same time, Derek dropped both of his legs down from where they had been resting atop Scott’s sturdy shoulders and wrapped them both around Scott’s slender waist, digging the balls of his heels into the dimples of Scott’s lower back. 

The shift of positioning only made it feel as though Scott was piledriving deeper with each thrust. And again, Derek’s body tightened. His heartbeat blasted into his throat, choking him out of being able to say much of anything. He could hear his own blood pumping in his ears. His toes curled hard. And his cock spewed out another massive load—this time sputtering out in-between where his abs were held tightly against Scott’s. 

Stiles cradled the sides of Derek’s face and gave a breathless laugh. “So lucky we maxed out your Cum Load Production.” He said, rubbing tears away from the corner of Derek’s glassy eyes. 

Derek tried to muster up enough strength to reach out for Stiles, but was immediately foiled by the sudden change up in positioning. Scott withdrew his fat cock from out of Derek’s reddened hole and then hopped up from off the mattress to stand with Stiles. Derek just looked on, totally fucked out, yet so hungry to get stuffed again. His hole fluttered. 

“Your turn.” Scott said. 

An entire hour ticked on by—not that anybody had actually cared to notice. Everybody had been far too busy. Scott and Stiles had decided to knock Derek around the confines of the bedroom, pushing and pulling Derek into all kinds of new positions. They had fucked him in any kind of way that they could think. After all, there had been so many different avenues to explore and Derek had been more than willing to please. 

In one instance, Stiles flipped Derek off of the mattress and shoved him down into the carpeted floor. Face smashed into the scratchy carpet, back beautifully arched, fat ass hiked up into the air, Stiles fucked Derek like some kind of sex god. He hammered his massive cock as deep as he could into Derek’s heat. All the while, Derek’s moans and screams were muffled against the floor. Derek’s fat ass wobbled with each thrust and his hands scrambled around in a desperate attempt to hold onto something as his body was jolted around. Unfortunately, all that he managed to blindly grab onto were some overdue library books and Scott’s dirty laundry. 

Thirty minutes into the hour, Scott had Derek picked up into his arms yet again— this time, shoved back up against one of the bedroom’s walls. As he held Derek up against the drywall, Scott pounded into Derek’s ass—mercilessly. Derek’s legs flailed around in the open air, unsupported by anything, as they just hung there. At the same time, Scott bit and lapped at the side of Derek’s neck— sucking bruises into Derek’s skin, only to watch as they faded away with werewolf healing. 

Forty minutes into the hour, Stiles had gotten another turn with Derek. And this time, he had elected to topple all of the neat stacks of paper and collectable knick-knacks that had lined Derek’s personal desk off onto the floor. And once the desk surface had been so clumsily cleared, Stiles had Derek sit atop the surface, ass and legs dangling off the edge. Stiles took hold of his own cock and then stuffed it back inside Derek, jumping straight back into an unyieldingly monstrous rhythm. 

And at the strike of the new hour, both Scott and Stiles had Derek back down on the ground—on his hands and knees. Scott had his cock fucked inside Derek’s ass, whilst Stiles took advantage of Derek’s open mouth. The two spitroasted Derek— rough and sloppy—each of their back-and-forth thrusts pitching Derek’s body on and off of another cock. And from the chirped whines that gurgled out of Derek’s stuffed mouth, both Scott and Stiles were sure that Derek liked getting spitroasted the most. 

“I need to cum.” Stiles breathed. 

Stiles was significantly more winded than Scott, but only because he was human and Scott was lucky enough to be a werewolf. Nonetheless, Scott felt the same way about needing to cum. His balls were heavy and aching for a release. Both of the two had fucked Derek multiple times, bringing Derek to blow load after load. Derek’s tanned skin felt tacky to the touch and glimmered with shiny seed. 

“Same.” Scott said, running his hands through his own sweaty hair. He looked back over to Derek’s now messy bed. “Finale time?”

“Finale time.” Stiles confirmed, a devilish grin tugged at the corner of his lips. 

Scott slapped Derek on the back and then pulled him up to stand from where he had been previously bent over the edge of his own mattress. Slick was leaking down the back of his thighs. As Derek took a standing position, he seemed to sway, completely unable to stand firm in his placement. His eyes looked hazy, but there remained an eager sparkle in the emerald color. 

Scott picked Derek up into the strength of his arms again, the same as he had done an hour prior when he had needed to lower Derek onto Stiles’ lap. But this time around, Scott just cradled Derek’s body in his own capable arms, almost like he was going to rock him away into sleep. Sleep— however, was nowhere near the intention. As Derek wrapped his arms around the back of Scott’s neck, utilizing his own strength to remain hoisted above the ground, Scott used one of his hands to reach down and guide his own dick back into Derek’s hole. 

He eased in slowly, this time making sure to savor it. Scott drank in the sound of Derek’s tightness squelch with wetness as he slid in, giving his hips a good and sudden pitch forward to watch as Derek’s eyes widened in pleasure. And then, Scott whistled and nodded his head in Stiles’ direction, motioning over for Stiles to come and take him place behind where Derek was held up and speared open on one cock. 

Stiles was about to jump out of his skin with glee. He looked a horrid wreck, all sweaty and disheveled. But he practically hopped over to his positioning and then grabbed hold of his cock. Slowly, like Scott had done, he too slipped his cock into Derek’s ass— laughing out the moment that Derek’s entire body shook and Derek whimpered out against Scott’s neck. 

“You can take it.” Stiles cooed, pressing his nose up against the back of Derek’s neck. “That’s the kind of slut we programmed you to be. Always open, always ready, so desperate to be bred.”

Derek gave a feeble nod and then looked over his shoulder to where Stiles was standing. He looked Stiles dead in the eye and then a dopey, half-cocked grin spread across Derek’s sloppy face. And at once, Scott and Stiles took that as the cue to start up their simultaneous thrusts. Derek’s smirk instantly morphed into a wide open breathy yell of surprise. 

Scott and Stiles hammered their cocks into Derek’s tightness, working in tandem with one another the best that they could to bring about their own orgasm whilst giving Derek the kind of pleasure that he was programmed to crave. Derek was so slicked up and wet that it was easy for the two to simply glide in-and-out of Derek’s heat, repeatedly, without needing to pause to readjust themselves. 

“He feels even tighter—FUCK!” Stiles groaned, pounding up into Derek. He couldn’t get enough of the combined feeling of Derek’s tightness and rubbing up against Scott’s cock. 

“Could a straight boy ever do this?” Scott breathed, looking up under his lashes to meet Derek’s glossy green eyes. “No—no way. No way you’re straight, Der. Thank god I can change it—change you—you’re ours.”

“Tell him, Scotty,” Stiles cried, speeding up his thrusts. Scott quickly matched the change in pace. 

“See that—?” Scott used one of his hands to grab at Derek’s gruff jaw, forcing Derek’s head to turn just enough to see where the tablet was innocently laying atop Scott’s bed. “It did this—it helped us. We rewrote you. Took you, took your mind, took your body, and rewrote it—everything, reprogrammed it, made you our whore— our slut .”

Stiles turned Derek’s face to look in the opposite direction, over to look at where Derek’s bed was messy and empty, slightly damp with sweat and slick. “Look at that—you rode us. You cried for it, begged, screamed for it. And you rode us, hard and long, like a fucking pro. And we gave it to you like we made you want it—pushed down, muffled away into your pillow, you rode our cocks.”

“—like—you’re—riding us—now.” Scott grunted out in-between each thrust. 

“fuckfuckfuckFUCK—I’m gonna fucking blow, fuck—fuck, Scott, fuck—! Stiles cried, grinding his teeth—hips starting to involuntarily lose their rhythm. 

Me too —FUCK— me too .” 

At once, all three felt their bodies draw high and then fall. They crashed. Scott and Stiles’ synced thrusts faltered hard as they felt their own cocks pump splash after splash of hot cum into Derek’s body, burning white hot into the overworked pink of Derek’s slick walls. So much so that their combined load quickly sputtered out around where Derek’s hole was wrapped around their combined girth, dribbling out to stain the carpet below. 

Derek came again—this time, noticeably harder. In fact, he came so hard that he half-wolfed out. His side-burns grew out. His eyes flared red. His nails elongated. And his fangs sprouted as he screamed up towards the ceiling—so loud that the windows of the bedroom rattled violently. At the same time, his cock spit out another massive load, splashing against Scott’s abs yet again. 

As the three came down, Stiles withdrew his spent cock and sucked in a healthy breath, satisfied with himself. Scott carried Derek over to his bed and dropped him down, watching as Derek’s body gave random, convulsed jolts. He was still coming down, harder than anybody else. But it was what he deserved.

Scott and Stiles met in the middle of the bedroom and embraced, wrapping their arms around each other, giving one another’s asses a couple firm squeezes and slaps. And then they slammed their lips together and made out for a few seconds, letting their heartbeats flutter down into post-orgasm territory. They laughed, surveying the ‘damage’. They looked so messy, Derek looked like a wreck, and now Derek’s side of the bedroom was equally as horrid as Scott’s. 

Fuck , now what?” Stiles asked, watching as Scott walked over and picked up the tablet. 

“We tell Derek to clean up his pig-stye of a room, take a shower, and then reset him back to his boring, aggressively heterosexual self.” Scott said, holding up the tablet, pointing at the ‘RESET’ function. 

“I don’t want to sound like a whiny brat, but damn— do we really have to? Reset him, I mean.” Stiles said, crossing his arms. His softened cock gave a slight twitch. 

“I mean, yeah—I can’t have mom catch Derek walking around with his little brother’s load dripping out of his ass.”

Stiles shot a disapproving glance over to Derek. “ Fine.

“Don’t worry, though— we have the whole rest of the week until your dad gets back.” Scott confirmed. “And now that you know about the tablet, we can do this whenever.”

Stiles just smirked, watching as Scott typed up some boring, chore-ish type tasks for Derek to complete once he caught his breath.
