"W-wait! Mr Stark is gonna-"
"Don't worry about that right now, hmm?" Pete whispered in Peter's ear, and got an instant reaction from him as the tips of his ears became redder by the second. He knew Peter's ears were especially sensitive at that spot. In fact, he knew every one of Peter's sensitive spots. After all, he and Peter were essentially one and the same, weren't they? Like two peas in a pod, two birds of a feather (or should he say two spiders of a web?), or whatever. They were, down to the very atoms that made up their bodies, the carbon copy of each other. Tony Stark had really outdone himself this time.
Pete resumed rutting his hips against Peter's with a new-found rigour. "Besides, I'm sure Tony would— hah— enjoy the show we're putting on for him if he walked in on us right now," he groaned. Below him, Peter had already been turned into a slobbering, whimpering mess as their clothed dicks slid messily against each other. Pete could feel the other boy's dick twitch uncontrollably the mention of their shared mentor-lover possibly walking in on their naughty act.
"In fact, he may be watching us through the CCTV and jerking off right n-". Pete was promptly cut off when Peter pulled him down by the neck and proceeded to shut him up by sliding his tongue into the other's mouth. Gasps and moans from both boys blended into one another and filled the spacious living room.
"Fine. Will you just shut up and—" Peter let out another gasp as Pete thumbed his perk nipple, "—and let me ride you already?" He ended his sentence on almost a petulant note, frustrated at feeling so empty still. Pete didn't need to be told twice though. He was already standing up and eagerly shimmying out of his boy shorts before Peter finished speaking, revealing that he was going commando underneath. When he looked up, Peter had rid himself of his shorts too, sporting only a pair of boxers, tented with a visible wet patch at the tip. His clothed dick irrevocably twitched again at the realisation that his clone had not been wearing any underwear this whole time. Pete secretly took pride in getting Peter to react like this. Licking his lips, he pounced back onto the couch and flipped them around so that Peter was straddling Pete instead.
"Off. Now." Pete pawed at Peter's boxers impatiently as the latter hurriedly peeled off the last barrier separating their dicks. With both of their dicks bare and drooling pre-cum, they were able to rut against each other with much less friction in the way. Pete gave both of their dicks a few quick strokes, gathering their combined pre-cum to slick his fingers up and moved to prod at Peter's hole.
"…Huh?" Pete's eyes widened slightly in surprise when the other boy's hole gave in with barely any resistance and already lubed up inside.
"I… prepped myself in the shower earlier…" Peter confessed, nuzzling his face in Pete's neck in embarrassment.
"Fuck- If I knew you were so eager then you should've called me to the shower and done it right then and there." Pete wanted— no, needed— to be inside Peter right now. He immediately shoved two of his fingers into Peter, sliding into his warm insides with ease and scissored his fingers to make sure he really was properly stretched. A soft moan escaped Peter's mouth. When Peter showed no signs of discomfort, Pete took hold of his cock and positioned himself right at the entrance, his tip catching onto the loosened rim, teasing the entrance but not angled quite right to slide in. This earned a high-pitched whine from the latter.
"Hurry up goddammit," Peter huffed. Frustrated, he reached around to grab Pete's hard cock himself and shoved it right up to the hilt in one smooth glide, perky ass meeting pelvis.
Both boys moaned in unison at the overwhelming feeling. One being enveloped by soft, warm, pulsing walls while the other feeling so filled and completed. As if this was where they were meant to be with each other all along.
"Ah- hah… You feel so good… Ah!" Peter said between bounces. His strong, thick thighs flexing in order to spear himself on the other's cock over and over again. His own weeping cock bounces along with the movements, flicking glistening pre-cum onto Pete's abdomen.
Pete smirked and let out a short chuckle that soon evolved into a punched-out groan. "That sounds kinda narcissistic don't ya think?" He said when he finally caught his breath. He knew that sex with a super-powered human with near unlimited stamina just like him could be intense, but it still overwhelmed him every time he and Peter fuck. Especially since when the two of them did it, they really went at it like two rabbits in heat. He wondered how Tony always managed to handle them both when it was the three of them together. Above him, Peter was also lost in his own pleasure, half-lidded eyes gazing right back into his but hips not slowing down.
"Sometimes I forget how mouthy we can be during ah- during sex," Peter replied with a mirroring smirk. He slowed his bounces to deep rolls of his hips and leaned down to capture Pete's mouth with his own, effectively preventing him from making any more snarky comments. They got lost in making out for a while, stray hands desperately clutching at hair or occasionally brushing against a pink nip.
Eventually, Peter shifted the angle slightly and let out a stuttering moan. Pete's cock had just hit the special bundle of nerves inside him straight on and it's causing a familiar sense of warmth to pool at his abdomen. The jolt of sensation made him momentarily weak and he collapsed onto Pete.
"There it is." said Pete, as he immediately grabbed hold of Peter's slender waist so that he could thrust up into that same spot, abusing it mercilessly over and over again. He was sure he'd leave deep purple bruises in the shape of his hands from how tight he was clutching Peter's waist if not for his accelerated healing factor.
"Ah! Hah… Pete. It's, it's too much-" Peter panted into the crook of the other boy's neck, turned into a blabbering mess as he could do nothing but take it. He looped his arms around Pete loosely, panting and moaning every time Pete's cock hit his prostate. Tears welled up in his eyes as he entered in a fucked-out, cock-drunk daze, tongue perpetually stuck out as the panting get louder and more uncontrollable.
Pete was not doing any better. The tight heat enveloping Pete like a sleeve just felt so good. Every time he hit jackpot at Peter's prostate, the soft walls clenched and pulsed around his cock, as if it was shyly trying to milk him for his cum. Pete grunted from the exertion but his dick never ceased to throb and leak pre-cum inside the boy above him. For a moment, all that could be heard throughout the living room were their incessant moans and plap, plap noises of skin slamming into skin.
"Shit… I- I can't hold out for much longer," Pete groaned into Peter's mouth after they shared another deep kiss.
"Then… Let's, let's cum together… Hah…" Peter sneaked a hand in-between them and took hold of his own dick, and started giving it quick strokes. He resumed riding Pete with renewed enthusiasm, his back arched in pleasure. This allowed Pete to latch his mouth onto one of Peter's cute little nipples right in front of him while he tweaked the other one with his fingers. He knew it would drive Peter crazy having his chest stimulated at the same time.
As expected, Peter immediately tightened his fist in Pete's hair and let out a near shout. "It's too much, it's too much… Ah!" he blabbered, though his other hand was still moving up and down his weeping shaft.
Pete released Peter's nip and began trailing kisses upwards, where he sucked a dark hickey on the side of the latter's neck. It would fade away soon enough, but it gave Pete a burst of satisfaction seeing his mark blooming on his other half at that moment.
He tightened his hands around Peter's waist. "Come on… Hah- Cum for me…!" Pete said as he coordinated his thrusts in time with Peter slamming his body back down on his cock. His abdomen tensed as he teetered closer and closer to his climax.
"A-ah! Mmphm…! I'm, I'm cumming…!" With a final slam on Pete's cock, Peter threw his head back and came with a shout. His cum flying through the air in an arch and landing on both of their abdomens. At the same time, the fluttering of Peter's walls caused Pete to finally release inside him, painting his walls white with his cum.
They eased to a slow grind against each other. Pete's dick still twitching from the aftershocks and Peter getting overstimulated from the sensation. Pete was still plugging Peter up, preventing his warm load from escaping and Peter just felt so light and fuzzy, floating away in his post-sex bliss.
They make out some more, like two small animals licking and cuddling with each other. Eventually, Pete's soft cock slipped out with a fwop, eliciting a surprised gasp from Peter. Creamy white release oozed out from Peter's puffy hole, dripping down onto his balls. Reaching around himself, Peter played with the cum so that it was smeared across his abused rim. Pete joined in by inserting two of his fingers back into Peter and spread his hole wider, allowing more cum to drip out lazily.
Peter shifted his glance to the peculiar glint hidden in the bookshelf behind him. Then, as if showing off the aftermath of their 'antic', he pushed his ass up higher so it was more visible.
"Mr Stark… Did you- hah… Did you enjoy our show?"
Thousands of miles away, Tony Stark watched the multiple security feeds spread out in front of him intensely. He promptly cancelled all of his upcoming conferences and called for his private jet as he tucked his spent cock back into his suit trousers.
He had to properly reward his boys for the little show they had put on, after all.
