So you probably didn’t mean this as a prompt but my lizard brain sort of glued itself to cock worship and I kinda ran with it.
TW: Daddy kink | Breathplay if you squint.
Peter had many things he adored about Tony. An almost endless list, in fact. There was very little he disliked, aside from Tony’s blatant lack of self care, love and respect.
If asked, he’d wax poetic about Tony’s selfless heroism, the way he laughed and the way he looked in a tux. His frighteningly intelligent mind and his sassy jokes.
But they were all, to some extent, a lie.
Or at the least, a half-truth.
No. Peter’s true favourite thing about Tony - Not to sound shallow - Was his cock.
When Tony’s sex tapes were leaked; Peter nearly wanked himself into exhaustion. Took the day off sick to stare slack-jawed and drooling at the shaky videos. Not even the shame of finding out they weren’t consensually recorded wasn’t enough to drive him to delete them.
And meeting the man in person, well. Seeing the way that cock stretched his slacks, the slight jut in thr armour to encompass its mass comfortably…
Even Captain America had resorted to the odd polite cough to bring Peter’s eyes back up to an appropriate level.
The first time Peter had actually gotten up close and personal with it, he’d cried. Literally. Genuine tears had streamed down his cheeks. Tony had been horrified.
Of course, the horror had quickly vanished when Peter had forced himself down on it, inch by underprepared inch, too eager to wait any longer. Too desperate to get a feel of it.
It was a need that had never waned. Not even five months later, when they had tentatively and unspokenly gone from just sexual to something a little more…More.
“Je-esus, kid! Take a breath” Tony hissed above him, practically curling over Peter’s head as the boy hollowed his cheeks, putting a Dyson to shame.
“You are literally-” Peter let his teeth skim the smooth, slick tip. “-The only person who’d complain during a blowjob”. He punctuated it by letting his tongue press firmly into the leaking slit, tasting the pre-cum there.
“I can, when you won’t let me cum” Tony grumbled back, relaxing against the headboard, threading his fingers through Peter’s hair tenderly.
Peter supposed he had a point. Tony had been on the edge of cumming earlier, hips shoving his cock deep into Peter’s throat, right up until Peter had pinned them down, let the suction drop, wrapped his fingers tight around Tony’s base.
Peter couldn’t help it. He wasn’t ready for it to be over. Wanted Tony’s cock in his mouth for hours to follow. Wanted it choking him until Tony was desperate to cum, until he took matters into his own hands.
He licked a fat, wet stripe up the side, then the underside; the other side, laving the hard, hot skin like a cold ice-cream on a hot day. Kitten-licked his way up to the tip and sealed his lips over it, sucked hard until his throat ached with it.
“Peter - Peter, fuck. Fuck. That’s it, baby” Tony groaned, using the handful of hair he held in a tight fist to try and pull Peter down. Peter braced himself on his elbows, resisted.
He wasn’t ready to let Tony cum. Not yet.
The night had started off slow, lazy. Peter had kissed and licked his way down Tony’s stomach, had spent almost twenty minutes simply mouthing at Tony’s cock through his jeans.
Had crawled his way up Tony’s body, ground against him in slow, circular rocks until Tony’s grip went tighter, until he tried to fuck up against Peter’s ass.
And that had landed them here. With Tony so hard his cock was red, verging on purple, so strung out and high on the dragged out pleasure he was rosy cheeked and glossy eyed, chest heaving as he panted.
He suckled his way back down the underside, to the sensitive dip where cock base became balls, suckled here as he used his thumb to abuse the slit, felt Tony writhing beneath him. Coiled like a spring.
“God, that mouth. That fucking mouth. Daddy can’t look at it without thinking about those pretty little lips all stretched around his cock” Tony breathed, and Peter whined even though he saw through the attempt to get him to sweeten up.
Relatiating, Peter steadied himself and sunk down on Tony’s cock, felt the thick stretch of it forcing his throat open, cutting off his air. Suckled and gurgled around Tony’s dick as his breath became short and Tony’s hips bucked in aborted little jumps.
“You’re gonna kill me” Tony whined above him, eyes round and revered as he watched Peter’s cheeks go ruddy. The boy hadn’t even had his cock touched in an hour, but he looked as wrecked as Tony felt.
Peter truly seemed to intend on sending him to an early grave, because some gentle bullying found Tony standing by the edge of the bed, watching in rapt wonder as Peter’s throat bulged around his cock.
“Daddy’s little slut” he cooed affectionately, went to pull out when Peter’s body begun to convulse slightly. But hands found his asscheeks, gripped the meat hard and pinned him in place as Peter squirmed.
“Shit, baby. Baby, let me go. You gotta breathe. You ca-an’t” Tony’s words broke as Peter choked around him, swallowed, finally let him go as the boy gasped for air, hanging off the edge of the bed.
Peter didn’t really give either of them time to recover, drooling as he painted for breath, wrestling Tony back down onto the bed and diving straight back onto his cock with sloppy, loose sucks, more a wet space for Tony to thrust up into.
“You’d swear my cock was a drug and you’re an addict” Tony huffed, gripping Peter’s jaw to pull him off, fingers flexing at the pathetic whine Peter let loose at being denied.
“Can’t help it” the boy drawled in response, wrapping both hands around Tony’s cock and pumping him in slow, twisting strokes. “It’s so perfect. So big. It’s yours”. Fought his way back down to suck the tip like it was oxygen.
Tony could have cum. With his cock twitching a drooling pre-cum over Peter’s tongue, with his hands in the boys hair and pleasure now a raging inferno in his gut.
He was denied.
“Baby. Please. Daddy’s begging you” Tony whimpered, voice rough as Peter kept him teetering on the edge, grip flexing and tongue curling around his cock, breath hot over Tony’s hip.
“Mm” Peter mumbled around him, vibrations making Tony’s whole body seize. He felt like a live wire, electric and ready to explode, fingers twisting harshly in Peter’s dark curls. Peter swallowed him down again, not choking himself but constricting his throat around Tony’s cock, tongue pressed flat and warm, an extra friction on each thrust.
Tony could feel it. Building. Raging. Consuming. Tried desperately not to show it in case Peter stole it from him for a third time, bit his lip and let his head fall back as he rocked up in the slick embrace of Peter’s throat.
Peter must’ve known, though, because as Tony cried out and buried himself down Peter’s throat, the boy swallowed him easily, cheeks hollowed and eyes closed, squeezed Tony tight as cum flooded the back of his throat.
He was sloppy and sticky when he pulled out, slapped his cock a few times against Peter’s swollen, plum-shade lips with a lazy, worn out smile. “Daddy’s perfect little boy” Tony praised, cupped Peter’s cheek.
He let out a rough sound when Peter’s tongue licked up his cock, oversensitive and done for, but the boy was only cleaning up, licking and suckling gently until Tony was cleaner and softening against his jaw.
“You suck dick like you’ll die if you dont” Tony mused, hauling Peter up, over his body to snuggle, the press of the boy’s hard cock digging into his hip, though Peter seemed content just to curl against him.
“A dick like that deserved worship” Peter rasped, looking up at him with a dopey grin.
And worship Peter did. Every blowjob was like a prayer, leaving Tony almost too far gone to bury himself in the boy’s ass. Sucking him down until he was glazing over from oxygen loss; until the ache of his jaw was visible in the way he ground his teeth.
But Tony had never felt more loved or more worshipped than when he was two hours into needing to cum, helpless beneath his boy as Peter licked and sucked.
