People say that two omegas together won't work.

How can it when both omegas want to be fucked? And even if one does want to top, omega cocklets aren't satisfying to be fucked with. Even a beta cock would be more satisfying than the little thing between an omega's legs.

To those people, Tony thinks they're just not thinking outside of the box. That they lack imagination.

Because Tony has absolutely no problem fucking pretty omegas. And the one he has in his bed is the prettiest of them all. His lover. His mate.

Peter.

Peter in heat makes Tony's mouth water. It also makes his pussy throb, desperate to have the other omega's slim petite cock fucking him.

But that's for another time because, yes. Heat. Peter's in heat. It's not Tony's turn to be mounted, no, it's Peter's, and Tony has just the thing.

His Peter is a size queen but even more so when he's in heat.

His omega is on his knees, ass in the air. Legs parted, his dainty little cock hard but barely visible past the fat plump lips of his pussy. He's already dripping too, trails of wet slick making a sizable damp spot on Tony's sheets.

"Tony– Please, Tony… Don't tease this time, I can't–" Those lean thighs tremble and more slick drips. Peter's voice wobbles with need and his scent grows thick and sweet in the air.

Tony takes a breath and his hand trails down to the impressive toy cock between his legs. His own cocklet is nestled within, cushioned in a tight wet squeeze. He wraps his hand around the silicone toy, idly playing with it while also getting it wet with Peter's slick.

The toy is an impressive nine inches in length and the girth of it is especially satisfying. He's had this one used on him during his own heat and his and Peter's preference in size sync up. Two size queens but more than willing to switch places to get what they both want.

The straps that hold the dildo in place are snug around Tony's hips.

"Shh, baby boy," Tony comforts him as he caresses the trembling muscles of Peter's back.

He runs his hand from the nape of Peter's bowed neck down to the small of his back. His thumb rests on one of the cute dimples Peter has there before he slides it further down to squeeze that tempting ass of his.

"I need it," Peter whines, his ass swaying in the air as though his pretty cunt isn't already pushing Tony into a feral state.

"I know, sweetheart," Tony says before he lines up, rubbing the fat head of the toy where Peter's sopping wet and needy.

He teases a little, but really, he's just getting it a little wet.

It's during one of Peter's whines and wiggles that Tony lets him have it.

The toy slides in with some effort despite Peter being wet. It helps that Tony has a hand on his hip, guiding the younger omega back onto his cock.

Peter hasn't had something quite this big in a while and Tony's omega cocklet isn't enough to prepare him for the sheer size and girth of the toy.

"Ah!" Peter cries out, relief and shock in that one breathless moan.

Tony doesn't let him have a breather. Once he has the toy dildo inside his toy, Tony makes sure to give Peter what he wants.

The heat is setting in, right on time, as is Tony who starts up his fucking.

He takes his role as Peter's alpha very seriously no matter that he's an omega himself.

Each thrust has Peter's body shaking and each thrust gets smoother and smoother as slick coats the toy and Peter starts to loosen up. Soon, the omega melts into the bed, abandoning his position.

A swift smack to his ass has him crying out and Tony hauls him back onto his knees.

"Tony…!" Peter moans in protest. His fingers are reaching for one of their fluffy pillows, wanting something to hold as he's being fucked.

"Not yet, baby," Tony commands.

His hips snap forward, their bodies clapping together, a satisfying sound. The toy sinks into the hilt, and Peter whimpers, gasping around the pleasure.

Tony pauses there, catching his breath

His own pussy throbs at the emptiness but he's used to ignoring it during times like these. His sole focus is on the needy omega gripping his bedsheets.

With one hand, he parts the boy's cheeks and hums in approval at the sight of a dusky untouched hole and Peter's wet pussy stretched wide around Tony's toy cock.

"Pretty," he comments even as Peter huffs in complaint.

Tony gives him another reason to complain as he drags the toy out of its snug little home. This, too, takes some effort, as though Peter's body realizes it's losing its source of pleasure and is clinging to the toy desperately.

"Tony!" Peter whines, hips trying to push back but Tony's grip stops him.

"Shh, shh, it's okay, baby. I know you need it bad in this pretty pussy of yours," Tony assures him. "But we can't ignore your other hole, can we, hmm?"

The toy comes out drenched in slick, sopping wet with it. It's perfect for what he plans to do next.

When he presses the thick head to that dusky hole, Peter stills.

"Yeah…?" Tony encourages with a slight push. He watches as the tip sinks in just the slightest, Peter's asshole twitching at the pressure.

He knows that the kid had been desperate before falling into Tony's bed. He had caught Peter stuffing both holes with his fingers, alternating between his pussy and his ass with desperate whines of Tony's name.

His Peter… Such a desperate slut during his heat and outside of it too. Tony knows it isn't enough to fuck his pussy, he has to give equal attention to Peter's tight ass too.

"Please" Peter whispers, his hips still twitching and this time, Tony loosens his grip.

The tip pushes against Peter's hole, that dusky hole stretching against the fat head. It pops in and they both moan.

The fucking continues but Tony is more careful here. A few fingers of hasty finger fucking isn't enough to loosen Peter's ass for this monster cock.

And yet, his boy takes it wonderfully with some care.

Peter shudders through each inch being swallowed and Tony knows when that huge length brushes against that sweet bundle of nerves.

"Oh… Oh, God, yes…" Peter moans, head dropping. Tony wishes he could see him as the pleasure twists the features of that much beloved face.

"Yeah… Feels good doesn't it, omega mine?" Tony purrs as his pace starts to pick up.

Peter is so beautiful, so alluring, with a cock inside him, whether it's a toy or Tony's.

"Mm… good…. So goood…" Peter's words are starting to slur, a good indication that the heat is advancing and that Tony is keeping a good pace to satisfy it.

"Good, good…" Tony grins, his sharp omega fangs making the smile more feral looking.

The next time Peter melts onto the bed, Tony lets him.

He follows his omega down, his chest pressed up against Peter's sweaty back and he doesn't relent in his fucking.

Peter's making desperate, eager sounds. The change in position must be good because he's clutching that pillow tightly, his face turned to the side. His cheeks are a pretty pink, his wet lips gasping open. His eyes are squeezed shut, pretty tears gathering at the corners.

"I'm gonna… Ah… I'm gonna… wanna come…" Peter moans, his eyes sliding open just a sliver. Those teary eyes are glazed over in pleasure. "Tony, please… Make me come… Wanna come… on your… mm, fuck, wanna come on your cock… Tony, please…"

"Of course, sweetheart," Tony presses against him even tighter, making his thrusts deeper.

He focuses on hitting that sweet spot, taking pleasure with every drawn-out moan even when he feels that pulsing emptiness inside his own body.

He gets Peter there and pushes him right over. Peter comes with a trembling moan, his body locking in place as he shudders through his orgasm.

Tony stills, not wanting to overstimulate him.

When Peter's body relaxes, Tony pulls out and detaches the toy from the harness.

In comparison to the dildo, his omega cocklet is much too small. But that's never disappointed his partners.

Peter barely has time to lift his head when Tony goes back to fucking his pussy, but this time, he plunges in with his omega cock.

Tony's pussy still wants to be fucked, but his cock is surrounded by such easy wetness that he momentarily forgets the urge. It's warm and wet, Peter's pussy trying to squeeze down on the cocklet burying inside him.

"Oh…" Peter gasps, head falling back to the pillow.

Tony fucks him with fervor, focusing on all the wetness and heat surrounding his cock.

Tony may not be an alpha but he understands and enjoys this urge. The need to fuck and especially the need to fuck Peter.

He pushes himself up, knees over Peter's hips as he plows in and in. He pushes Peter's asscheeks together to give him more friction. He may have fucked Peter loose with the toy, but he can barely feel how loose Peter's gotten when they're like this.

"Mm… Mm…" Peter moans in complete abandon. "Fuck me– Tony… Oh, your cock feels so good… Love having your cock in me…"

"Yeah…?" Tony encourages, breathless. "You like my omega cock better than that alpha toy? I dunno, baby… Think you're just trying to stroke my ego here…"

He gives another forceful thrust, one that actually has Peter's body pushed up the bed.

"You don't need it," Peter huffs in breathless laughter. He's momentarily amused before pleasure has him moaning once more.

"Noo… " Peter refutes. He tightens up beautifully, his muscles squeezing down nicely on Tony's smaller omega cock. "Love your omega cock, Tony… Feels so nice… so warm…"

"Yeah? You like it when I'm fucking you raw, you mean?" Tony teases him. "Like it when I come inside you, filling you up with my come? Think you can get pregnant for me?"

"Oh…!" Peter gasps, always turned on by talk of Tony impregnating him, especially during his heat where the chance is the highest.

Subconsciously, his legs try to spread further apart but no, Tony isn't having it. He keeps Peter's legs pressed tight together so he can get the sweetest friction on his cocklet.

"I can do that…" Tony promises him, "You're in heat, after all… Perfect time to get knocked up…"

"Yeah…" Peter sounds dazed. "Do it, Tones, I need it…"

Tony leans down, tracing the bite mark on Peter's mating gland with his tongue.

"I know you do, sweetheart… I need it too…" Tony tells him in absolute truth. "So just lay there like a good omega and let me breed you up, alright, baby? You can do that for me, can't you?"

"Mm… Yeah, gonna… let you put a baby in me…" Peter is full heat now but he's a limp doll for Tony to use as he's being fucked.

He's leaving it all up to Tony, complete trust in his partner to take care of him.

And Tony does.

He keeps to his promise and fills Peter up with multiple loads. Each load Tony puts into his omega keeps him nice and wet, not that he needs it with how much he's slicking up.

He even manages to pop a baby knot, a nice surprise that has Tony muffling his moaning against Peter's neck. It's not as big as an alpha's but the extra girth has Peter moaning as he's filled a little more than normal. The load is larger too, despite how many times Tony's come inside him.

It takes Tony a little longer to recover after that attempt. The small knot is oversensitive that fucking, even with short deep thrusts, has Tony's brain overloading and creaming Peter's pussy a few seconds later.

The strap-on gets further use because yeah– size queen. He needs to keep his omega fully satisfied and if he uses the toy to fuck his come as deep as he can, then it's for a good purpose.

A day before his heat ends, Tony is once again fucking him with the strap-on. His come froths up where the toy plunges in and out and it drips down in messy trails on Peter's thighs.

His omega is barely conscious, fucked out and the only thing coming out of him is the contented purr of a satisfied omega.

Tony takes him again, tugging Peter's legs around his waist as he fucks the omega's loose pussy with his cocklet. Another load, Peter's body stuffed full but taking every drop even if it gets fucked out later. it only gives Tony another excuse to fill him up again.

"You…" Peter is barely conscious but he's peering at Tony through the slits of his eyes.

"Me?" Tony smiles at him, indulgent and willing to fulfill any request his omega has of him.

Peter lifts a limp hand and tugs on one of the straps for the harness.

"Your turn," Peter slurs.

"Aww, baby, thanks for thinking of me," Tony kisses his forehead but Peter throws an arm around his neck and tiredly nips his ear.

"Please, Tony," Peter whines at him. "Want you to feel good too."

"I have been feeling good," Tony promises him, rubbing up and down his arms with a comforting hand.

"Your turn," his stubborn boy complains with another tug on the harness.

And while Tony hadn't lied– the proof is how stuffed Peter's holes are with his come– he can admit that the idea of getting that dildo in his holes is appealing.

"Okay, baby, okay," Tony relents.

It takes some effort but he cleans up the toy and gets Peter strapped up. He licks his lips as the spent omega continues to lie there, every limb boneless with pleasure.

"I'll do all the work," Tony assures him as he straddles Peter's hips. The heat takes so much out of an omega and even if they're fully satisfied by the marathon fucking, the energy is leached out of them in the aftermath.

Tony sympathizes so he wants this to be as easy as possible while fulfilling Peter's stubborn but loving request.

He aligns the toy to his pussy and Peter looks up at him with a pleased smile. He takes it with a grateful moan, every inch stretching him to the point of satisfying fullness.

"Oh… Fuck, yes," Tony moans as he rocks and grinds on Peter's lap.

He loves how deep it goes, how wide it stretches him. The toy reaches inside him like it's making room for itself. If he presses down right underneath his belly button, he swears he can feel it there.

"Just lay back, baby," Tony says with a gasp as the strap pushes deep inside to where that incessant ache had been since the beginning. "I'll take care of it."

"Wanna see you feel good…" Peter complains. His hands grip Tony's hips, helping to guide him into a nice rhythm. But his poor boy is too fucked out and his attempt becomes futile when he can barely keep his eyes open.

It's of no concern to Tony who continues to fuck himself on the toy. He's done his job in satisfying Peter's heat and he's allowed to have this.

Peter has slipped into unconsciousness but that's the good thing about having toys like this. Tony can continue to take his pleasure, his entire body rocking on top of his mate's and the toy remains nice and hard inside him. The plus side is he can still look at his pretty omega even as he gets off.

Tony has his turn and he has a second, his pussy squirting slick out from around the thick girth inside him. His hard cocklet spills a load on Peter's stomach and Tony purrs as he marks his omega as his.

Peter wakes up for the third round and invigorated, he helps fuck Tony with a more forceful grip and thrusts of his hips.

He tumbles Tony onto his back, taking the older omega with determined thrusts and making Tony's toes curl. His pussy is being fucked open, the length of the toy making room inside him. Tony comes to another satisfying orgasm, clutching his mate close as he falls apart.

Afterward, Tony pulls him down into a sloppy kiss, engaging in a messy make out that has both omegas purring contentedly. His lips tease Peter's even as the younger omega slips into a well-deserved rest after days of fucking.

Who says two omegas can't satisfy each other? No alpha has ever satisfied Tony like this and he wasn't even the one constantly being fucked.

As he gathers Peter into his arms and he nuzzles against his neck, he purrs his own contentment.

Tony thinks he's done rather well at satisfying his mate.
