After School Alpha

Summary: Omega Peter had a bad day at school and Alpha Tony is going to make it better.

Rating: Mature

---

"I can't - I'm just - ugh," Peter flops onto the couch, reeking of distress and upset.

The moment the little omega had come into the lab Tony knew something was up. His protégé was normally bubbly, excitable, almost uncontrollably hyper, but today the teen had been quiet and, if Tony dared name an emotion over it, sad. The alpha figured he'd give the boy some space to work out whatever it was that was going on in his head but after a sharp clatter of tools a minute ago he'd carelessly asked, 'you okay, kid?'

Which resulted in Peter tripping over his words before planting himself face-first onto the couch in the corner of the lab.

The alpha tried - and failed, drastically - not to notice the tight curve of the younger man's spine where it rose to his ass when he walked over to that corner of the room. He simply couldn't help it; Peter was everything in an omega that Tony's craved: beautiful, incredibly smart, submissive - but only to an extent - and with the most compact little body it made his mouth water.

He tried not to think about this as he laid one hand over the younger man's waist in comfort, crouching down to the side of the couch. Petting down his spine, he released soothing alpha pheromones, letting his scent pervade the little space and draw the omega out of the shell he'd mentally crawled into.

"C'mon, kid," he rumbled. "I know you're not that upset over anything happening with your project over there. What's up?"

Peter shuffled until his face was turned toward Tony, the rest of him still firmly planted between the billionaire's hand and the couch. His eyes were round and as doe like as ever, but the tilt in his brow screamed small and soft and sad. Tony's heart broke at it and he took his free hand and ran his fingers over the creases and frown lines until Peter's face lay smoothed out and more tranquil than it had been all afternoon.

"It's stupid," the teenager muttered, pressing his face into Tony's hand, rubbing at it with his cheek like a cat begging for pets. The older man barely withheld a chuckle at the action and instead ran his fingers through Peter's soft, fluffy curls.

"It can be stupid and still suck," Tony replied, tugging at a loose strand of hair. It made Peter arch his neck in a way that showed off his mating gland and oh there were those feelings he was trying more and more to tamp down. It was one thing to want to fuck a pliant little omega like Peter, but a whole other thing to want to claim him, mate him, breed him full of Stark pups.

Tony was a dirty old alpha and he really didn't need the reminder of what he couldn't - shouldn't - have.

"It's just - " Peter started before sighing and closing his eyes. A moment later they opened back up again and stared right through Tony's soul. "You probably don't wanna hear this especially from me but," the kid swallowed before his face firmed up in resolution. "I love you, Mr. Stark, and it just really, really sucks because you don't look at me like that and you don't have to - like I get it," he rolled his eyes at himself as though he wasn't actively sending every atom of Tony's existence into a supercollider, "I'm just some dumb kid you have to like babysit to make sure I don't die doing Spider-Man things. And - and," his voice hitched and wavered with building tears, "you're so kind to me like all the time like even right now and you take care of me and I can't help what I feel and - "

"Hey," Tony said softly, moving both hands to cradle Peter's face. "Shh, don't cry." He wiped away the tears that had built on the younger mans face with his thumbs, smoothing away the tracks until they were gone and he had a handful of soft, pretty omega.

"'M sorry, Mr. Stark," Peter hiccupped.

"There's nothing to be sorry about, kid," Tony shook his head, hands resuming their path of running through Peter's hair, soothing them both.

"I just don't wanna make you feel bad because of how I feel," Peter frowned. "I just didn't think I could hold it in any more after - after Flash said all that stupid stuff today about being a b-burden." Tony frowned and made a mental note to deal with whoever the hell this Flash kid was. "And even just telling you how I feel is gonna make it all awkward and - "

"Pete," Tony interrupted, every part of him finally aligning to do the one thing he's wanted to do for months. "You aren't a burden, kid, and you're not making anything awkward. You've got nothing to be sorry about."

"But - !" Peter started and Tony rolled his eyes playfully before ducking forward.

Their lips met in a kiss that was, without doubt, the best kiss Tony had ever given or received in his many years of life. Peter's lips were soft and plush, warm, and the scent of sour feelings and surprise quickly was overrun with arousal and pure unadulterated happiness. Almost immediately his delicate little throat let loose an omegan purr of contentment and Tony growled back, proud and possessive over the little thing in his arms.

He pushed himself until he was laying over the teenager, crowding him into the cushions of the couch, weighed down by Tony's larger, alpha form. Their kiss was turning from almost-innocent to downright sinful with their mouths opening, tongues pressing against each other in a dance as old as time.

Peter let out a little whine when Tony maneuvered them to where the younger mans legs were spread around Tony's hips and the alpha thrust down. He pulled back and let out a loud growl as he ground his hips into Peter's, the omega mewling out little sounds of pleasure. Pete tried to match the rhythm of Tony's grinding but was too inexperienced and blinded by pleasure to sync up so Tony ran a hand down to his hip and guided him.

"That's it, little omega," he panted, face pressed against Peter's mating gland as he breathed in the scent of happy, slick, yours. "Take what you need, sweetheart."

"Mr. - ah," Peter mewled, strong hands grasping at Tony's shoulders, hanging on for dear life. "Alpha, alpha, alpha," he panted, back arching as he finally found the right pace to rub his jean-clad cocklette and pussy over the bulge in Tony's slacks.

They both moaned when Tony's cock hooked into a slick indent in Peter's jeans and caused them to grind in place, the only thing stopping their coupling the barrier of their clothes.

"Pete," Tony panted, pressing the teens legs up and around to hook over his hips. He ground down again and again, the slick dripping from Peter's hole drenching his pants. He could feel it on his cock and the scent and knowledge of just how wet the kid was for him was driving him insane. "Fuck, so wet, baby. Is that all for me, huh, kid?"

"Yes - yes all for you, alpha," Peter panted, arching to allow Tony's cock to thrust deeper into the cradle of his thighs. He whined as his jeans stopped the older man from fucking too hard against him. "Need," he cried, tears of frustration gathering at the corners of his eyes. He was the prettiest thing Tony had ever seen.

"Can't - can't breed you yet, 'mega," Tony said, voice coming in huffs as he continued to thrust up into the sweet slick heat of Peter's most sensitive spot. Peter whined, long and low, his whole body begging to be breached and fucked and knotted. It pulled at Tony's heart and his knot started to swell like he was some teenaged pup ready to blow his load in his pants.

Might as well be, he thought, for all that Peter was driving him insane.

"Alpha, please," Peter cried. "Need - need - "

"Need alpha's cock?" Tony teased, rocking them together as tightly as he could. "Need to be bred, Petey?"

Peter let out a choked off moan as his head fell back, overwhelmed by the idea. "Yes, yes, yes," he agreed, rutting against Tony frantically. He was so close. "Need alpha's cock in me," he admitted, rushed, frantic. "Need his knot," he panted. Delirious with arousal and instinct, he said, "Wanna be bred full of his come, wanna give him - give him so many pups." He cut off with a moan when Tony thrust particularly viciously against his pussy.

For Tony's part, he was just as frantic with lust as Peter was. Hearing the omega, his omega beg for his knot, beg to be bred and become the mother of his pups was driving him insane. But he couldn't, not yet, wouldn't breed him until they were mated and they would be mated, he'd figure out a way how.

But until then -

He pulled back and Peter all but cried at the loss. "Shh, little omega," Tony said, hands moving to remove every piece of clothing covering his little mate. "It's okay, alpha's gonna take care of you." He threw Peter's shirt off first before his hands dexterously started unbuttoning and tugging down jeans and underwear.

"Please," Peter begged, legs colt-like and fumbling as he tried to help. Finally, he was completely naked before Tony's gaze and instead of covering himself like he always thought he might - the embarrassment of being naked a truly terrible thing - all he could think was to stretch out, spread out, show off for his alpha, his mate. Let him see what he owned and was about to mark up and make belong to him. He ran his hands over his flared hips and up to his flat chest, touching everywhere he wanted Tony to touch. "Please," he asked again, soft and full of want.

The billionaire leaned down again and kissed the teen full on the mouth, hands immediately roaming to everywhere he could touch. He tweaked the boy's nipples until he gasped, he ran calloused fingers over the sensitive flesh of his ribs and the soft skin of the inside of his thighs before finding his goal.

"Oh!" Peter exclaimed before dropping back into a deep moan.

Tony's fingers found the boy's cocklette and pussy and smoothed over the soft flesh with his hands before dipping a fingertip into his sopping went entrance. "Fuck," he grunted, Peter's hole was warm and more inviting than it had any right to be. "So fucking wet for me, baby," he said, dipping a second finger in when he realized how loose with arousal the boy was.

"All for you," Peter agreed, spreading his legs even wider, begging to be fucked by Tony's hand.

And fuck Tony did. He thrust both fingers fully into the boy who in turn let little ah, ah, ah noises as the alpha's fingers thrust in and out of him. He was already so incredibly close to coming it was insane.

"Please, alpha," he begged, grinding his hips down every time Tony thrust his thick fingers back into him. "Please, please, please."

"Gonna make you come, 'mega, don't you worry," Tony promised. His fingers were so drenched with slick it was amazing his hand hadn't just slid right out. And, god, thinking about all that hot liquid running over his knot was driving him insane. "C'mon now, pup," he said, crooking his fingers until Peter screamed. "Come for alpha, come on my hand, baby."

"Al - alphaaa," Peter cried, body tensing up and eyes rolling to the back of his head. He grabbed the arm of the couch behind his head and held on tightly as his orgasms crashed over him. He vaguely heard the snap of the wooden frame but truly could not care about it as waves upon waves of pleasure rushed over him.

Slowly, he came back down from his orgasm, feeling himself slumped against the couch cushions, crumbled couch arm held loose in his hand. He let go of the fabric and keened when he felt Tony swipe his whole hand up against Peter's pussy.

"Shh, Petey, just need - ah," the older man said. Peter cracked his eyes open to see Tony's cock finally free from his trousers and the older man's hand wrapped tight around it. His cock was glorious, thick and long and angry red at the tip, dripping precome as the billionaire wrapped his hand around it. He jacked himself off in quick, efficient strokes, the glide smooth with Peter's slick.

The teen shuddered, body trying and failing to rev back up because of the erotic image. Tony's eyes were trained between Peter's legs and, in a moment of confidence Peter didn't know he hand, the teen pulled the back of his thighs with both hands, tilting his hips and putting himself on full display for his alpha. "Fuck," Tony said, hips stuttering in their rhythm. He squeezed almost painfully tight against the knot at the base of his cock at then - hot streaks of come shot out, marking Peter from chest to pussy with wave after wave of alpha come. He let out an omegan purr again, happy and aroused and so fucking hot from the display of pure desire from his alpha.

After a few moments, both men had calmed down enough to clean up using one of the many rags from around the shop before curling up together on the couch. Peter, still naked, was pressed tightly against Tony's larger, warm form. For his part, Tony grabbed a blanket from the back of the couch and covered the both of them, wrapping his arms around his little mate.

"Gonna mate you, kid," he promised lowly, leaving a kiss to soft, brown curls.

"Oh, alpha," Peter sighed in contentment. He tucked his head against Tony's mating gland and laved it with his tongue, breathing in the happiness in the air.
