💗💗💗

Typical alpha, Tony thought, amused, when Peter scrambled to make himself presentable.

All this was still new to him so as he was putting his clothes to rights, his cheeks were tomato red and he couldn't bear to make eye contact with anyone.

Kid, Tony wanted to say with fond exasperation, I'm the one that got tackled and fucked like a bitch in heat. How are you going to act so self-conscious now?

But he kept it to himself. Peter was, after all, still just a silly pup just growing into his own adulthood. Sex and all that, as liberal as alphas and omegas were, was still new to his poor nephew.

So Tony didn't tease, not even when Peter had to tuck his still half-hard cock into his pants with a wince. Then he fussed over his Uncle, helping him onto his feet and apologizing repeatedly.

"I'm so sorry, Uncle Tony. I didn't… It's never been that strong before and I just, I know it's no excuse but…" Peter ducked his head, gripping Tony's arm.

Once he was back on his feet, Tony took control as the experienced omega. He ignored the unpleasant way cum was starting to leak out of him and just patted Peter on the arm.

"Come along, puppy," Tony commanded and this time, he snagged the boy's wrist. Giving the boy a once over, he found that Peter was compliant and was easily tugged along.

Even then, he kept an eye on the boy. He had learned his mistake.

As they made their way to the elevators, he shot an apologetic look at the receptionist but nothing more than that. He wasn't going to test the poor pup's control though he did have to make sure they'd have to come back and address his actions.

Peter happily followed him to the elevators and while the boy fidgeted in place, Tony reassessed what he'd have to do to guide his boy.

"Alright. Well then," Tony said as the doors opened to the penthouse. "We're gonna have that talk and then we'll start on teaching you all about the birds and the bees, the alphas and the omegas. But first–"

He pushed Peter down onto the couch and reaching into a box he had on the coffee table, he tossed the retrieved item to the boy.

Peter caught it instinctively and then looked up in shock.

"Uncle Tony…?"

"Yep," Tony said cheerfully with a clap of his hands, "A cock cage. I was going to wait to use it but seeing as your instincts are a bit stronger than I anticipated and I need you to focus, I'm gonna need you to put that on for now."

Peter stared down at the cock cage but he was a smart boy and didn't protest. Tony could see, though, that the thought of putting it on was actually turning the pup on. That bulge in his pants hadn't been there before and although it wasn't meant as a form of punishment, Tony wasn't about to jerk him off either to get his dick soft enough to cage. The boy's brain would surely think it was a reward.

"Now, while you're doing that, I'm gonna go take a shower," Tony told him.

"But Uncle Tony!" It was that that made Peter protest, clutching the cock cage and looking up at his uncle with pleading eyes.

"Peter, you're sporting a chub just thinking about it," Tony pointed out, "And I don't blame you but if I get your pants off, that cock cage isn't getting put on. So I'm gonna take a shower and you can calm down or rub one out– pick your poison– and if you need any help, Friday can pull up some how-to's and guide you through it."

The young alpha pouted at that but only muttered something along the lines of I'm not asking Friday for help with this.

"She sees and knows all, kid. Might as well utilize her if you need," Tony called over his shoulder as he made his way to the bathroom. "I expect that cage to be on when I get back."

Once in the bathroom, he got the shower turned on and the temperature was just a little hotter than he liked.

"Friday, baby girl, pull up the cams from the living room?" Tony requested as he started stripping off his clothes. He made a face at the patch of wetness in his underwear, splotches of his nephew's drying cum and his own slick.

He forgot how messy dealing with rutting alphas could be.

A little hologram popped up from his watch and he got a clear view of what his nephew was up to.

Damn, the boy took orders well. He didn't waste a second once Tony had left.

Peter was curled up on Tony's couch cushions, his face pressed up against something black. The pup had grabbed the discarded hoodie that Tony had left on the armchair and was huffing into it, greedily inhaling his uncle's scent. Between his legs, Peter was hastily jerking off, one hand wrapped around his thick girthy cock and moving at a pace that looked like it could hurt.

Fortunately, the alpha pup was leaking so much already that he had plenty of lubrication from the pre-cum alone. The benefits of being an alpha in rut or close to one anyway, all that pre-cum just dripping out. It had certainly helped when Peter mounted him in the lobby, too impatient, too eager to get his cock inside him.

The sight of Peter, his sweet alpha nephew, jerking off to his scent did funny things to Tony. Once again, he dismissed it as his omega side being pleased to be so obviously desired.

"Cheeky pup," Tony murmured, partly amused but also feeling a lick of heat igniting somewhere below the belt. "Better not get any of your spunk on my hoodie, I swear that kid is too comfortable sometimes."

Peter's cock was truly impressive, Tony thought as he supervised a moment longer. No wonder it had stung when the kid had stuck it in him. He would have to caution Peter to prep with at least four fingers before shoving that monster in anyone's pussy, maybe even fisting for anal? Tony wanted to squirm just thinking about it.

"You can shut it off, thanks, Fri," Tony said, feeling all sorts of flustered. He licked his suddenly dry lips and felt the growing warmth in his belly.

"Focus, focus," Tony said, then ducked into the shower.

He took his time, conscious of Peter rubbing one out just a room away. The hot water helped with his aching knees and his aching body, but it didn't help extinguish the heat that was building low in his belly.

He ignored it and washed thoroughly. Under the spray of the water, Tony admitted to himself that while he had gone into this a bit skeptical, he was actually looking forward to it now.

He also admitted that he had been worried that becoming Peter's omega mentor in this way would ruin their uncle/nephew relationship. Their interactions after the lobby incident put that worry to rest. Once Peter's base instincts retreated, he didn't treat Tony differently, didn't revert to calling him omega in a derogatory way. Didn't think he owned Tony just because he had fucked him.

He was still Tony's sweet alpha nephew. He was just a horny mess of an alpha when his instincts ruled his mind.

Tony could handle that. In fact, that was the whole point of this. Train the pup so that he wouldn't be a menace and could actually control those instincts and be a contributing member of society.

Satisfied that he had given Peter enough time to jerk off and hopefully put the cage on, Tony left the bathroom in an oversized fluffy white bathrobe. What was the point of clothes if he was just going to take em off anyway?

Like a good puppy, Peter was waiting for him in the living room. Nothing gave away what he had done while Tony showered and Peter was even on his phone.

As soon as Tony came into view though, he scrambled to put it away and sat up, straight and proper, like an eager student awaiting instruction.

The cock cage was nowhere in sight.

Tony nodded in approval. "Did it give you any trouble?"

"Uhh, no, it was fine," Peter said, flustered.

Tony noticed his hoodie was nowhere in sight but decided not to comment on it. It wouldn't be the first time his nephew stole a shirt or hoodie of his.

Instead, he told the alpha, "Alright, let's see it."

It took two seconds for the words to register but when they did, Peter's mouth dropped open.

"Okay," the alpha complied, breathless.

Once on his feet, he hesitated, hands on his pants zipper. Tony gave him an encouraging nod and with a deep breath, Peter shoved his pants and underwear to his thighs.

Tony gave a low whistle when confronted with the sight of Peter's alpha cock caged.

"Uncle Tony," Peter whined, embarrassed, but he didn't make any move to hide himself nor did he step away when the omega stepped closer for inspection.

The cock cage was clear plastic, top of the line for alphas. Peter's soft cock filled it nicely, neither too snug or too loose. A small padlock at the top kept the cage locked.

It looked nice or maybe it was just the sight of Peter's cock in chastity that Tony found appealing. To test it, Tony got on one knee and got a lot closer. He placed a hand on Peter's stomach to steady himself and he felt the flex of muscle underneath his touch.

"Not uncomfortable?" Tony asked as he ran a finger down the clear plastic covering Peter's cock.

"Uh…" Peter's eyes were wide when Tony looked up at him. "No, just…"

He closed his eyes and took in a deep breath, visibly trying to get himself under control. The cock cage did its job and the poor alpha was still soft though he was no doubt feeling turned on. This close to the boy and Tony can smell his arousal, thick and coying, trying so hard to entice and lure in an omega mate.

Tony patted the caged cock then got back to his feet. He didn't want to tease the boy too much but he couldn't help but exact a little payback for the lobby.

"You can pull your pants up," Tony told him then sat on the couch. He patted the space next to him. "Now, we have some things to discuss."

Gingerly and maybe with a bit of disappointment, the alpha covered up and sat down.

"I don't blame you for what happened in the lobby," Tony told him, "But it did give me a lot of things to think about. So here it is, kiddo, a performance review from yours truly."

He got the boy's complete attention and Peter straightened up, curious.

Tony started to tick off what he'd been thinking about in the shower.

"So let's see… These scores will be out of five," he explained. He held one finger up, "First up. One out of five for the alpha bullshit."

Peter flushed but didn't deny it. Tony had ranted enough times in the past about alpha bullshit– an alpha's uncontrollable jealousy and possessiveness. Their inability to reign in their instincts. At the very least, it was inconvenient and rude and at its worst, destructive and dangerous.

No one wanted an alpha that couldn't control themselves.

"Okay, I get that," Peter accepted easily.

"Your instincts are newly coming in," Tony did say, giving his nephew some slack. "So I don't expect you to be able to control yourself entirely yet. Hence the low score. Even in that state, you only got me away from another alpha instead of attacking. I think that's a pretty good base to start with."

The words comforted the alpha pup and the upset turn of his lips softened. He was still unhappy with his own behavior, which was fine, but he trusted his uncle's judgment.

"Okay, Uncle Tony," Peter acknowledged.

"Next, pleasuring your omega…" Tony was between giving him a two or a three but ultimately decided on the lower score. "Two out of five. You touched my cock at the beginning which was nice– very nice, actually. But I think that was more due to you being curious. In the end, I got a nice orgasm out of it but it was more to luck and the size of your dick than anything else."

"Oh!" Peter was pleased and mortified. Pleased Tony derived some pleasure from Peter's fumbling attempt but also mortified that he had been so caught up in fucking that he hadn't tried to get Tony off himself. "I'll work on it…"

Tony patted his hand, "I know, kid. That's what this is all about, after all. There's other stuff too, like how I enjoyed it but other omegas might not like the rough fucking as much as I do."

"You liked it?" Peter perked up like the cute puppy that he was.

"That's what you wanna take from that?" Tony gave him a look then rolled his eyes, "Yeah, I liked it but as your mentor, I have to remind you, or well, teach you, to be conscientious of your partner."

Clearly, Peter wanted to debate this more but Tony wasn't going to budge on this. Looking at Tony's face, the boy finally nodded in acceptance.

"Okay, Uncle Tony," Peter said then added, "I'll be more observant."

Satisfied, Tony then rattled off the next score, "Good. Alright, next one. One out of five for sex safety– You came inside without permission. No condom either."

And because Tony was guiding him, the omega conveniently left out that he happened to like creampies so this, in regards to him, was a non-issue. Tony had to think about Peter's possible future lovers or mate, after all.

The blushing alpha nodded once more, no objections, so Tony continued.

"Foreplay," Tony said, "also a one out of five, don't mind it too much since I'm sure you'll be better once we get some lessons in. Just something to have in mind."

With that comment, Peter's eyes took on a glazed look and Tony patted his hand to get his attention again.

He did, however, raise his brow at the alpha. "If you have any requests, I can, of course, put them into my lesson plans. You've always been a bright kid but I'm sure having a subject you're interested in wouldn't hurt."

"Yeah... I'll keep it in mind," Peter said, voice coming out faint. Tony can practically see the thoughts whirling around in his nephew's pretty little head and well, he was curious for sure.

What did horny little alpha pups fantasize about besides fucking a wet omega hole? Tony will surely find out since his nephew was definitely not one to hold back when it came to learning.

Tony barely stopped himself from squeezing his thighs together. They were talking about sex so wasn't it only natural for Tony to get turned on? He wasn't a young omega anymore but he wasn't dead either.

Clearing his throat, Tony finally came to the last point. Sadly, this was the big one that Tony felt was so so important to teach baby alphas coming into their own. There were too many knotheads out there and Tony refused to let his sweet nephew become one.

This matter was also one that disappointed Tony because Peter was such a sweet kid so he hadn't expected the younger alpha to do so poorly here. He thought that anyone lucky enough to be his nephew's partner would be showered with love and affection.

Finding out otherwise was… disappointing but it was okay because Peter was still learning after all.

"Affection… Gotta give you a zero, kiddo," Tony told him, obviously disappointed and letting it show.

"Affection…? Wait, what?" Peter was shocked at getting such a low score.

Tony patted Peter's hand and despite his own disappointment, he knew that Peter would strive to do so much better now that he was aware.

"Kid, you didn't even kiss me or anything," Tony explained to him. Even now, thinking about it… His nephew had lost his virginity without even having kissed him first.

Peter's face turned so red and for the first time since Tony started the scoring, he couldn't meet his uncle's eyes.

"Uncle Tony, that's not…" Peter fumbled over his words and then blurted out, "I didn't know I could kiss you!"

What?

Tony stared, incredulous. "You wouldn't kiss the omega you're mating?"

Peter's eyes jumped to him and with a shamed flush to his cheeks, he said, "I would but... You're Uncle Tony! I didn't think you'd want me to… How was I supposed to just kiss you like… on the lips?"

Ah… it suddenly made sense. In a proper setting, of course, Tony would instruct the boy on how to touch him. How to kiss him. But their lessons had not started in a proper manner due to Peter's overriding instincts going haywire.

And yet, Peter had managed to avoid kissing him because hadn't wanted to be rude, of all things.

It was… cute. That suddenly made everything much better and Tony's previous view of his nephew once again realigned.

Silly pup.

"So you fuck me but don't kiss me. That hurts, kid," Tony gently teased.

And because they were so in sync with one another, Peter groaned, knowing he was forgiven.

"Uncle Tony, I would've kissed you if I knew I could," he said with a whine, pressing closer against Tony's side and burying his face against the omega's shoulder.

Tony smiled, gotcha. He knew exactly how to proceed now and avoid all that… weird awkwardness in getting into the physical aspect of their lessons.

"Well, you can," Tony told him, matter of fact, "So. You should. Maybe I'll even revise my scoring since there was some misunderstanding…"

Peter looked up, eyes wide. "Right now? Like… right now?"

Tony smirked and caressed the boy's red cheek with gentle fingertips. "Unless you have some other excuse to give? You wanna keep the zero?"

Peter shivered under his touch, eyes still so wide. Tony could see the desire in them and it called up some of his own. This was good. Their compatibility was amazing, which was something Tony knew because they got along so well. Alpha and omega compatibility was different though so being compatible in this way… It was like the cherry on top of a sundae.

"I haven't gotten a zero on anything since like… ever…" Peter muttered, eyes dropping to Tony's lips and stayed there. "If it's okay then…"

Tony tilted the boy's face towards his in encouragement.

"I said it was okay, Pete, so go for it. I won't judge, promise," Tony told him. Peter gave him a look cause obviously he was judging if he was assigning points but still. "Okay, I won't judge harshly so go on already."

Peter stared at him a moment later and their faces were so close. He could count each of Peter's eyelashes if he wanted to. Then those eyelashes fluttered close and Peter leaned up, hands hesitatingly cradling Tony's face, and pressed his mouth chastely against Tony's.

It was over a second later and Peter pulled away.

"Was that okay, Uncle Tony?" Peter asked, eyes dipping to Tony's mouth eagerly before shooting up to Tony's eyes.

Tony felt a faint wiggle in the back of his mind, a suspicion…

"Was that your first kiss, sweetheart?" Tony asked.

Peter's expression shuttered but he gave a tight nod. "Yeah… Did I do okay…?"

Oh… oh… May was going to murder him if she found out the details of Peter's time with him. Losing his virginity before even having his first kiss…?

"It was perfect, Pete," Tony told him and it was for a first kiss. Peter had held him gently and had cautiously but eagerly kissed him. There hadn't been any tongue or anything remotely dirty about the kiss but it was Peter's first.

Tony hummed. "We can start the lessons now or… we can order food and watch a movie. Leave things for tomorrow so we can start fresh. What do you think? Had enough for today?"

Peter hesitated but didn't even have to think much before saying, "The sooner I learn, the better, right? I want to start… If you're okay with it, Uncle Tony."

"I wouldn't have offered if I wasn't up to it," Tony told him honestly. "Alright, so kissing… we can practice a bit, just see how things go and what feels natural."

"Okay," Peter breathed out, "Can I kiss you again then?"

"Yeah, you can kiss me again," Tony told him with a grin.

His nephew didn't need any more encouragement.

Fortunately, he didn't launch himself at Tony. Getting tackled once a day was more than enough. Peter did eagerly press against him, hands kind of hovering in the air, unsure of where to put them before he settled them on Tony's shoulders.

Their lips met again and it was the same close-mouthed kiss, innocent and sweet. Peter repeated this a few more times, breathing getting shaky at each one. Tony allowed it, letting the young alpha get a feel for it. Each time, Peter's hands slipped further down from his shoulders until finally, Tony guided one to the back of his neck and the other around his waist.

Peter eagerly obeyed and pulled his uncle close until their chests pressed against one another's.

Tony felt the need to take the next step so instead of letting Peter continue his cute closed-mouthed kisses, he cupped the alpha's face. When he moved away, Peter tried to follow but he held him off just long enough to instruct him.

"Open your mouth a little, pup," Tony instructed him and he could see Peter's eyes dilate. "I'll show you another way to kiss, the next step, if you will."

The sweet boy obeyed beautifully so when their mouths met again, Tony made sure to tilt his face just so… and let their mouths slide together in a more intimate kiss.

The omega hummed in approval when Peter's breath hitched in his throat and he pressed even more into his uncle. Their slips slotted together perfectly and just as Peter was getting used to kissing in this fashion, Tony introduced his tongue.

"Mm…!" Peter groaned, eyes squeezed shut and arms winding around Tony's back and almost crushing him with his strength.

Tony quickly reprimanded him with a harsh nip to his lip, one that made the alpha gasp and loosen his hold. Tony pressed his advantage, wrapping his arms around Peter's neck and controlling the kiss with the angle he was coming in.

It got hot and heavy fast. Tony could feel his nephew trying to control himself, most likely being urged by his instincts to push Tony down and cover his body so that no one else could see him. It was those possessive alpha instincts again, rearing its ugly head even when they were alone.

Maybe when Peter had better control, he'd allow it but for now, he slid his fingers into Peter's curls and with a harsh tug, pulled the alpha back so his throat was bared.

"Uhh!" Peter groaned, dark eyes wide and so so hungry.

His lips were kiss swollen and wet with spit, pretty lips parted open as he softly panted.

"Instincts riding you hard, hmm?" Tony murmured and at the sound of his voice, the younger alpha shuddered, hands twitching against Tony's back.

And just because he can, he reached down between Peter's legs and passed a perfunctory pass over the alpha's caged cock. Still caged, still soft.

The action had Peter whining a soft, "Uncle Tony…"

Ugh, it was such a pity that Tony had to be the responsible one.

His hips twitched into Tony's touch as though doing so would give him some sort of friction and therefore some relief. It wouldn't and they both knew it.

"Uncle Tony… Please…" Peter muttered, going lax in a truly un-alpha way. It was trusting… Submissive in nature. It fed Tony's appetite to dominate the younger alpha.

"I know, baby, I know. You're doing so well," Tony cooed to him.

He released the boy's hair and without further ado, shoved him so his back met the plush arm of the couch. In another second, Tony was on top and straddling his nephew, ass settled over his lap.

"You can touch," Tony told him and immediately Peter's hands were back on his waist, fingers no doubt eager to touch but still maintaining some sort of decency by keeping them above his ass.

The kissing resumed but now it was more of Tony consuming the boy, rubbing against his body, his ass grinding against his caged cock. The omega's scent filled the room, overpowering and domineering.

His poor nephew wasn't prepared. With the full assault of an omega's scent, Peter got drunk off it in seconds. The soft groans and pitiful moans his sweet boy made as he clutched Tony's waist with greedy hands were so delicious. It was just as addictive as his mouth, Tony decided.

He had no choice but to let Tony take control but he replicated everything his uncle did to him. Slow strokes of tongue against tongue, gentle and harsh nibbles to a plush nip.

Peter proved himself to be the quick learner that Tony always knew him to be. It became less of a lesson and more of an actual make-out. It was perfect, exactly how a young pup like Peter should learn. Tony hadn't even needed to nudge the boy into being aware of subtle cues, Peter seemed to pick it up naturally.

There were still moments when they didn't meet perfectly. Tony pulled back once and their noses bumped on the next kiss. It was a quick fix, Tony gently correcting their positions until their mouths slid wetly together, soft and perfect.

Once Tony was certain Peter got the hang of it, the omega gave one last tease of his tongue. He was delighted when Peter took initiative and swiped his tongue over Tony's, following the omega's invitation until they were once more kissing.

By the time Tony urged him back, they were both panting. Tony knew he was slicking up already and his cocklet was half hard. The boy was still caged though, he could feel the hard plastic of the cage against his ass and it gave him something nice and hard to rub against if he allowed it.

He wanted to but this wasn't about his pleasure so he refrained.

"Better," Tony praised him with a lick of his lips. "Much much better. I'd give that a three."

"Three…" Peter breathed. "If we keep going, can I get a four?"

The eagerness with which Peter asked made Tony chuckle.

"We can keep going, but we can change it up a bit."

He leaned back and Peter instantly followed, sitting up with the omega in his lap. He easily supported Tony's shifting weight and the omega leaned more into it, trusting his nephew to hold him.

"Here," Tony tilted his head to the side, fingertips tracing the delicate column of his neck. "Kiss here. No biting. Yet."

"Oh…" Peter breathed, more than excited.

"Kissing is more than lips and tongue, kid," Tony told him, trying to hide his own eagerness.

"Got it, Uncle Tony," Peter murmured before ducking his head and pressing his lips against Tony's neck.

At the first touch, Tony didn't hold back his reactions. Peter needed to learn not just what Tony was teaching him through words. He needed to learn how to read his partner's body, the subtle hints that would tell him to stop or continue.

"Ah… That's nice…" Tony breathed as Peter's warm breath caused his body to shiver in excitement.

The pup breathed heavily against the sensitive skin of his neck and Tony realized Peter was savoring the scent of him.

"You smell so good here, Uncle Tony," Peter told him, breathing deeply, lips pressed to skin.

"Hmm…" Tony hummed in acknowledgment, eyes closed and just enjoying the way Peter carried out his instructions.

The young alpha's affections were obvious as he pressed kiss after kiss onto his uncle's skin. He continued to obey Tony's rule of no biting, but Tony did feel the hint of teeth once or twice but it was never hard enough to actually count as a bite.

He allowed it, running his fingers through Peter's curls and urging him higher and higher until he was close enough to kiss again.

Bodies once more rubbed against each other, mouths and lips pressing together.

Peter groaned with his uncle on top of him, his hands finally slipping further down to cup Tony's ass.

"Uncle Tony…" Peter whined.

"No fucking tonight," Tony told him and still he pushed back against Peter's touch, sighing in pleasure when the alpha squeezed and groped his ass.

The young alpha whined at the statement but didn't try for anything. Good.

Hmm…

"How's the cage holding up?" Tony asked him.

It took a second for Peter to realize he was being asked a question but once he got it, he murmured the answer against Tony's collarbone.

"I'm not… hard… It kinda feels weird, like I know I should be but…" a harsh breath is exhaled against Tony's skin. "God, Uncle Tony… You smell so good… Taste good too, I just wanna put my mouth all over you… Taste you everywhere…"

Now, that sent a searing heat right through Tony's body and it was obvious in the way his scent spiked.

"Ah… If I had a category for dirty talk…" Tony sighed, leaning into Peter's hands and guiding the boy down to where his bathrobe was gaping open. "Would've given you a four off the bat."

"Uncle Tony…" Peter murmured, voice going soft and pleading. "Do you think I can kiss you… down here?"

He squeezed Tony's ass, a clear indication of just where he wanted to put his mouth next. The thought was tempting, very tempting. Tony hadn't had his pussy or ass eaten out in ages and looking into Peter's eager face, he was so so tempted to continue in this guise.

Reluctantly, Tony reigned himself in. He had plenty of time to teach the boy, he didn't need to rush. But God, this entire thing was turning out to be more of a lesson in patience for Tony.

"We'll add it to the list," Tony said, voice certain but mind screaming at the denial. The alpha pup was good with his tongue, Tony had learned, and he could only imagine how it'd feel against his holes. "For now, this is a lesson in affection and kissing, pup, so get back to it…"

And yet, Tony didn't lead Peter's mouth back to his. He guided the boy to his chest and Peter eagerly took the hint, running his tongue around a puffy areola before taking on the peaked nipples. The cheeky boy did slip one side of Tony's bathrobe down his arm in order to get better access.

The omega just shrugged the entire thing off, allowing it to pool around his waist.

The room was set at a nice warm temperature of 75° F so the full body shivers Tony experienced was all from Peter's hungry mouth suckling on him.

"Oh…" Tony groaned, head tilting back and back arching as Peter gently lapped at his nipple.

The empty feeling in between his legs ached and the more Peter played with his chest– one hand coming up to tweak the neglected one not in his mouth– the more Tony wanted to just hump against the hard ridge of the cock cage. His mind was becoming hazy in the growing pleasure and Peter wasn't faring any better.

Even when the alpha couldn't get hard, he was still a horny mess and following some of those instincts that wouldn't relent because he had an aroused omega in his grasp.

Peter's hips pushed against Tony's ass, the hard cage giving Tony such sweet friction where he wanted it. It had the omega clutching the pup's back, eyes squeezed shut and fighting against the rising force of his orgasm.

All the while, Peter's warm wet mouth made soft wet sucking sounds against his puffy nipple.

"Teeth–" Tony ended up gasping, "Just a little."

Tony groaned at the hint of teeth on his sensitive nipple. It was perfect.

Their hips were moving in rhythm now, even with Peter still caged. Thrust for thrust, both omega and alpha panting and spiraling from the scent of pheromones thickening in the air.

"Mm–" Tony sighed when Peter switched to the other nipple, leaving the one he abused peaked and shiny wet with his spit.

"Doing good, Pete… Such a good alpha," Tony praised him, fingertips massaging over his scalp. His back arched once more when Peter gave a particularly hard thrust, his arms keeping Tony in place so he felt the cage rub against him.

Fuck… Tony thought faintly. He just… really wanted to come. And considering how selfishly Peter had fucked him in the lobby, he was owed an orgasm or two.

But Tony was a generous lover and even if Peter had fucked him without reserve or thought for his own orgasm, he wasn't going to do the same. He wanted his partners to be satisfied, to be so out of their mind in pleasure that they were a boneless mess at the end.

So even though Tony had declared they'd only be kissing tonight… He reached into the pocket of his bathrobe and without Peter realizing, unbuckled his pants and slipped his hands in.

"Ah!" Peter's surprised moan meant he finally realized what was going on. "Uncle Tony, y-you're…! Oh, yes– yes, yes, yes! Thank you, Uncle Tony, thank you…!"

The cage came off and Tony was quick to wrap his hand around Peter's soft cock which didn't stay soft for long. With a lapful of omega and his uncle jerking him off, Peter's alpha cock grew rapidly, becoming hot and flushed with blood in seconds.

"Oh… oh… Uncle Tony… Uncle Tony…" Peter whined, hips bucking needily and completely out of control.

Like before, once his cock got some stimulation, he lost focus of what he was doing so sadly, Tony's stiff little nipples became neglected.

Tony led the boy's mouth back to his own and at least this time, compared to the first, Peter eagerly seized his mouth in a kiss.

"Just this once, kid," Tony panted against his mouth. His hand was already dripping wet with pre-cum, the alpha too excited and leaking furiously with every stroke. "Tomorrow– Tomorrow, we're getting down to business. But for tonight, gonna make you come, pup. Think we both deserve a little reward for the successful kissing lesson…"

"Oh… Mm… Love kissing you, Uncle Tony…" Peter moaned, staring at his uncle with dark eyes.

"Mhmm…" Tony agreed, "My boy's a good kisser… Only had his first kiss today and already so good at it…"

Peter whined, the pleasure pushing him beyond words. His hips jerked, sloppy and hard, with every stroke of Tony's hand. And just like before, the poor pup didn't last long.

He barely had any warning before he was shooting off, but he did give something like a warning, an urgent "Uncle Tony–!"

It was an improvement.

One hand flew to his knot but was pushed away for Tony to take care of it.

The boy fell apart in his hands, his eager cock shooting off with a thick load despite having already come earlier. It made such a mess as he spilled in stripes and covered Tony's hand in a cloudy glaze and some spurts shot high enough that it splattered over the omega's exposed chest.

"God, kid, it's like you're so pent up even though I know that's not true…" Tony panted even as he eked out the last few drops from Peter's cock.

He eyed the thick cloudy drops of semen on his fingers and fuck it– he'd already gone back on what he was going to do, he might as well do what he wanted.

Tony popped his cum covered fingers in his mouth, licking off the taste of his nephew with a few swipes of his tongue.

"God, that's so hot, Uncle Tony…" Peter murmured, slumped against the couch but staring fascinated at the pink of Tony's tongue swiping over his fingers. Then he groaned miserably, "You didn't come."

"Hmm…" That was true and Tony was feeling a bit frustrated over it, but it wasn't something that couldn't be fixed.

"Let me eat you out, Uncle Tony…" Peter all but pleaded, but Tony shook his head. He was too… needy… to allow the kid time to explore and learn how to do it properly.

If he didn't take care of himself now, they were going to end up going at it, he just knew it. The pup's cock was already trying to perk up and Tony wanted to set some sort of boundary, okay.

"Just sit there and look pretty, alright?" Tony instructed as he took his own cock in hand and started to jerk off. He lifted himself from his nephew's lap, his other hand going between toned thighs and sinking two fingers where he was dripping wet.

"Watch," Tony breathed out, eyes drifting closed as he focused on his own pleasure.

Watch and learn. A flimsy instruction but Tony just wanted to get off so he pushed his body quickly to the edge.

With his fingers soothing some of the ache and his cocklet getting some attention, it was easy for Tony to get there.

Surprisingly, the thing that pushed him over the edge was a soft wet mouth closing over his nipple. His eyes flew open at a harsh suck, a strangled "Pete–" as he wobbled on his knees.

The alpha's arms stabilized him, Peter's hooded eyes looking at him hungrily.

"Ugh…!" Tony came with his nephew's mouth on his nipple and one hand jerking his cocklet while the other stuffed his pussy.

The orgasm swept all reason away, and when he collapsed against the pup, Peter nuzzled against his sweat damp neck.

"Fuck, kid…" Tony said once he regained his breath. "You're such a Stark… Only wanna listen when it works for you, huh?"

Peter kissed his neck and gently eased Tony's fingers from between his legs. Then he was licking the slick from Tony's fingers and that was answer enough.

"Brat…" Tony said fondly even as Peter gave him a cheeky smile and licked his lips.

They kissed again, leisurely this time, and the taste shared between them– Peter's cum and Tony's slick… Delicious.

💗💗💗

It's a Friday night and usually, he has a nerdy hang out planned with Ned but SI is hosting a gala tonight.

So Peter will make an appearance and he'll take as many pictures with his genius father as the photographers want. The questions, though, he'll field to his dad. They're always asking when he'll be mated off and who the lucky alpha would be.

Peter knows he's a genius like his dad but sometimes he really wonders how no one could see his father's plans for him.

The omega shrugs it off as he trudges his way toward the parking garage where he knows Happy is supposed to pick him up.

There's a limo there instead and the distinct familiar figure leaning against the side has Peter perking up.

"Dad!" He calls out surprised but pleased. It's not like it's uncommon for Tony to swing by but with how fast things have to move for the Gala, he hadn't expected to see his father until they met up at the event.

Tony gives him a cheerful wave and when Peter gets close enough, the alpha envelopes him in his arms. His dad nuzzles against his neck, inhaling the faint scent of books and ink and nestled deeper, his omega son's unique one.

Peter indulges in it, letting his father scent him as much as he pleases. When Tony finally pulls away, Peter smiles at him.

"Thought you would be too busy to come today," Peter says with a bright smile.

"Never too busy for my favorite kid," Tony says seriously.

"I'm your only kid," Peter says cheekily. He takes a step towards the limo door only to gasp in surprise when his father pushes him against the shiny polished surface. "Dad…?"

"As my only kid," Tony says, "gotta make sure you're ready for tonight."

There's some shuffling behind him before Peter realizes that his father is going on his knees. His hands are pressed against the tinted windows, but he sees the way his breath fogs up the glass. His cheek feels warm, too, against the cool surface.

It comes as no surprise then when he feels his daddy pulling his pants and underwear down.

Since they hadn't fucked in the meeting, Peter's body has been in a state of arousal since then. His body is just too used to a fuck, quick or otherwise, when his daddy gets his hands on him but their schedule is so tight today.

His pussy is getting wet, of course it is. How can he pretend to be unaffected? He feels his daddy's breath against his exposed ass, his fingers gently rubbing and spreading the slick around with soft wet sounds.

"Dad…" Peter complains.

"I'm sorry I couldn't fuck you properly earlier," his daddy apologizes, "A quickie probably isn't in the works right now either. Don't wanna tire you out too much before the big event."

"I can take it, dad," Peter protests fiercely. "You've made sure I can take anything you dish out to me so don't…"

His father's insinuation that Peter can't kind of annoys him because he's Peter Stark. Only he knows how to thoroughly please his father. Even when he's thoroughly used and dropping, he can handle anything his daddy wants.

"Mhmm," comes his daddy's hum of approval but Peter isn't sure he's even listening.

His daddy's too focused on playing with him and he does play.

Tony grips his ass and spreads his cheeks apart with just his thumb. Even if he looks over his shoulder, Peter wouldn't be able to see what his dad is up to so he just waits.

He doesn't have to wait for long. His daddy thumbs the tightly furled hole of his asshole and finds it dry. The light touch makes Peter clench up instinctively.

"Daddy wants to use my ass?" Peter asks curiously, shifting on his feet and wiggling his hips a little. With the time crunch they're in, he figured his dad would just do a quick fuck and hold off on knotting.

"It's too tempting not to, kid," his daddy admits. "Just for a little bit, okay?"

"Mmkay, you can use it whenever you want, dad," Peter says, "I'm your omega, after all."

Tony purrs at the words. "That's right, isn't it? My good omega son."

Peter shudders when his daddy moves his hand between his legs, rubbing against his pussy lips and dipping into his wet hole. Peter's already wet so when Tony starts to leisurely pump his fingers in and out, Peter moans in appreciation.

It's not what he needs– he needs his dad's cock– but it's good enough.

Peter leans his forehead against the window, fogging it up even more with his breath.

His heart jumps when the window he's leaning on jerks down just slightly.

"Boss, we need to get going," Happy calls from within. "Is he– Pete, let your dad know cause we gotta get going."

"Mmk–" Peter barely acknowledges it but he calls out to his dad with a soft moan. "Dad, Hap– Hap says we gotta go."

His daddy's fingers persistently jab inside him, fingers circling and rubbing in a spot that has Peter's eyelids fluttering. Another deep press has the omega biting down on his lip because it's right where the knot would sit. The pressure isn't the same, so it's not the same as being knotted, but it still feels good.

"Just need a minute," his daddy says.

Peter repeats it to Happy but he's barely aware of doing so. He only knows that the window rolls back up because his fingers leave streaks where his breath had fogged up the glass.

"Dad… daddy…" Peter whines. His voice echoes and bounces around in the large open space of the parking lot.

His alpha daddy gives one last shove of his fingers, one last jolt of pleasure that has Peter arching his back before he removes them.

"Keep it down, kid," Tony reminds him and then those slick wet fingers return but not to his pussy. They nudge against his back hole, one finger testing the tightness before sliding in.

Peter gasps and holds very still, trembling, as his daddy works his asshole open. It's been a while since their morning fuck so his hole is tight but still soft and ready for use.

His daddy prepares him diligently, slicking up his back hole with the wetness from his pussy. Peter opens easily, knowing to relax and push back so that the prep takes almost no time at all.

His hips push back, chasing after the pull of his father's fingers. It's a different kind of pleasure, getting fucked in the ass. But it's one that Peter's gotten used to.

He expects his daddy to press him against the limo once he deems Peter ready.

Instead, his alpha yanks the limo door open and Peter gets shoved inside. His chest is pushed down against the expensive leather seats and he scrabbles to get up.

Hands grab into his hips, keeping him right where his daddy wants him. His alpha's cock is pushed inside his hole, fucking in halfway before his father pulls out and does it again.

"Mmph!" Peter groans and clings to the seats as his ass gets fucked.

His daddy fucks him from behind and he steadies himself. His jeans help to cushion his knees and his daddy's hands keep him in position.

"Boss!" Happy complains from the front, "Pepper's gonna kill me if we're late. We gotta get Peter ready for the gala too."

"Ah…!" His daddy's cock pushes up right against his prostate.

It doesn't seem as though his father would stop and Peter revels in it even when he feels bad for causing trouble for Ms. Potts.

The alpha reaches around, fondling Peter's hard cocklet as it drips and stains the floor of the limo. He gives another thrust, sinking in deep and making Peter gasp as he sees stars. Then Tony grinds in deep, savoring the closeness of their connection, the tightness of Peter's ass.

He stills and his hands slip back to Peter's hips before sliding down, each warm palm settling on his cheeks. Then similar to earlier, he spreads Peter's ass apart and gives a hum of approval at what he finds.

"God, look at that hole trying so hard to take cock," Tony groans in appreciation. He rubs at the reddened hole, the tip of his thumb threatens to breach the already stuffed rim.

Peter clenches even tighter around his daddy's cock, breathless with how full he feels. When Tony doesn't do anything else but admire the view, Peter gets impatient and bounces a bit. He rocks on his dad's cock in an attempt to get him to continue.

"Ugh, hold on, Pete," Tony grunts. He pulls out a couple of inches and then spits to where his cock is exposed. When he sinks back in, the renewed wetness makes it even slicker and easier to slide in.

To Peter's dismay, his dad doesn't resume fucking him like before. After a few more thrusts, his daddy pulls out completely and leaves the omega feeling unfulfilled. Peter's about to turn around and complain when a swift smack against his backside has him jolting.

"Get in, kid. I'm not done with you yet but we gotta get going, as our dear Happy keeps reminding us." Tony says. His cock is still glistening wet and so hard, twitching between his father's legs.

Peter eagerly obeys, holding onto his pants as he gets in. His daddy slides in after him and tugs at the omega's pants.

"Get these off and get on my lap," he instructs Peter. Then to Happy, he says, "Let's get rolling, Hap! We got a gala to attend."

Peter kicks off his pants, leaving them in a heap on the floor along with his underwear.

Happy starts to drive off as Peter moves into position. He wobbles on his feet as the limo moves but with his daddy's help, he sits on the alpha's lap.

Tony's cock is hot against his bare skin and he shifts up.

"It'd be so much easier if you just used my pussy, dad," Peter complains when he blindly tries to position his dad's cock at his other hole.

"I love all your holes, Pete, but just get my cock inside this sweet ass of yours. Don't want your pussy too sore for tonight so it's this hole fo now," Tony says patiently even with his voice strained.

He's helping Peter balance while Peter finally presses the alpha's cockhead to his rim. Once positioned, Peter sinks down on his father's cock and they both groan when he fully sits on Tony's lap.

Peter presses a hand against his belly and groans when he feels Tony's cock twitch inside him.

"Go on, kid, fuck yourself on daddy's cock," Tony orders him. He helps Peter bounce on his dick, his hands tight on the omega's hips.

Outside, the sky is starting to darken and once they join the road, other cars flank the limo. The windows are tinted but uncovered so even from where Peter's sitting on his daddy's lap, he can see other drivers and passengers and even the buildings as they drive on.

Peter eagerly continues his bouncing, helping along with the movement of the car, though it sometimes gives him trouble. He doesn't want to slip off his daddy's cock, though, so eventually, he keeps his bouncing to a minimum. It's just enough stimulation to pleasure his daddy.

At one point, his daddy helps him turn around so that his knees settle on either side of his daddy's hips. This position is much easier and he tucks his face into Tony's shoulder, drinking in the scent of his alpha.

"Happy, can you turn right here?" Tony interrupts.

By then, Peter has his eyes closed, just focusing on his daddy's hands, his voice, and his cock.

His eyes shoot open when they hit a rough patch of road.

"O-Oh!" He cries out when he falls back against his daddy's chest. "Mmph!"

He quickly realizes this was his daddy's plan all along because the rough patch of road doesn't end. They've turned down a bad stretch of road that's partially under construction and each pothole, each rough bump, has Peter bouncing roughly in place.

His daddy is enjoying it immensely and Peter… Peter is too distracted by the now rough fucking. He's barely catching his breath and has to cling to his father.

His daddy's cock is fucking into his ass roughly, in and out– Every bump has him bouncing higher than intended and when he drops, it's to the shock of his daddy's entire alpha cock shoving in from tip to hilt.

Peter barely has control and only had the help of his daddy to keep him in place. He ends up giving himself over to the mercy of the road and his own luck and just braces himself for the rough fucking.

By the time they get back on smooth clean road, Peter's come twice and has ruined his daddy's clothes. His daddy also came, shooting off a load into his ass but making sure to keep his knot from shoving in. As a result, they've made a mess between their legs, his alpha daddy's come spilling from his used hole.

His daddy has shoved two fingers back into his asshole, swirling the mess of alpha come and slick together.

"We're here," Happy announces cheerfully.

Peter groans even as his daddy finally pulls his fingers out and gently pats his ass. His hole feels a bit sore but it's nothing he can't handle, especially since it's more than likely his daddy only intends to use his pussy for the gala.

"Time to get ready, kiddo. Hope you're ready for tonight."

His legs feel like jelly but Peter huffs against his daddy's neck.

"'m okay, dad. Just… maybe carry me in?"

Tony chuckles but Happy opens the doors, his daddy does exactly that and brings Peter in his arms to where their team is waiting to get them ready.
