💗💗💗
This was heaven, Peter hazily decided.
He was drunk on Tony's milk, his hands holding down the omega's wrists above his head. His mouth was latched onto one of his omega's nipples, the hard little nub encouraged by swipes of his tongue to give him more and more.
The milk flowed, sweet and consistent. A good supply of it came with just the barest hint of encouragement.
The studded alpha pulled off, swallowing down the sweet omega milk with a satisfied sigh. Beneath him, his omega was sprawled on his back, his tits exposed through the narrow V of his unbuttoned shirt.
Peter had perhaps popped a few buttons off but the visual was worth it. The fine fabric of Tony's shirt was pushed to the sides, almost framing the gentle swell of his chest.
Both nipples were hard, one still shiny wet from Peter's mouth and the other was dripping milk from the neglect. There was an endearing flush that had traveled down the omega's neck and it crept down his collarbones and made his chest flush pink.
With a gentle touch, Peter reached out and rolled the neglected nipple between two fingers.
Tony let out a high pitched moan, restless. Milk beaded up between Peter's fingers and he ached to take that drop between his lips. He'd clean up the mess, giving his sweet omega a nice suck before lapping up the spill of milk that had trailed down to where his shirt was pushed aside.
But first–
"Mama," Peter called to his mate.
A new game, a new exciting element to this play between them. It made his omega so wet and it made Peter's alpha dick drip.
Tony's eyes snapped open, hunger and desire quickly tucked away to make the game more realistic.
Peter was playing the role of a possessive alpha son and his sweet milky mate was his Mama. It was a fantasy but one that both got them going.
"Pete," Tony said, a hesitant smile on his kiss-swollen mouth, "You've had enough?"
Beneath him, Tony's body trembled with pleasure even as he half-heartedly pushed against Peter's grip.
"Let me up, kiddo," Tony said as though Peter not letting go was just a matter of the alpha forgetting. Tony's gaze darted to the door of their bedroom before coming back to the alpha on top of him. "Your alpha father will be home soon, I should get ready…"
Alpha father? There was no other alpha besides Peter– Oh.
Peter's breath caught in his throat as another element to the game was introduced. Tony had never mentioned a pretend alpha before.
Even knowing it was part of a game, the younger alpha's instincts flared in possessiveness at the thought. It was easy for his emotions to become volatile, for his mind to go hazy with heightened instincts.
The thought of another alpha was just another trigger and Peter's grip tightened to an almost bruising strength on Tony's wrists.
"Mama," Peter groaned as he leaned down, aiming for Tony's neglected nipple.
"Pete–" Tony protested, futilely kicking his legs against the bed.
Even with one hand, Peter was able to hold his Mama's hands in place. His other hand traveled down past the open button-up shirt and settled on his omega Mama's slight baby bump.
He'd made his claim clear. Everyone could see it, even this pretend alpha who threatened to take his Mama away.
"He still doesn't know, huh, Mama?" Peter groaned.
Between his legs, his alpha cock was starting to thicken. It had already been half hard but now, with the need to claim, it was growing even harder in preparation.
"He'll be home soon, baby," Tony threw out as though it would deter his young alpha son from fucking him. He clearly felt the heat of Peter's cock and the way it was starting to fatten up, thicker and longer than any of his previous partners.
"He doesn't know," Peter repeated as he bent down and licked around Tony's neglected nipple, catching the drops of milk on his tongue.
"Don't– I don't know… ah… what you're talking about, Pete." Tony kept pretending though his voice went breathless. Peter knew that the sensation of his tongue swirling around and teasing the omega's puffy areola felt good.
Tony stifled a moan as Peter finally stopped his teasing and pulled the nipple fully into his mouth, engulfing it in heat even as the milk dribbled out onto his tongue.
The alpha allowed him a moment of reprieve but only because he decided that drinking down the creamy sweetness was more important. Tony's body arched into his once he started suckling. His fingers twitched weakly in Peter's grip as the alpha pulled milk from his body, groaning around the sweet creamy taste.
When Peter was certain that Tony was made limp and docile, he pulled off just enough to murmur his next words like sweet nothings into a lover's ear.
"The pup is mine," Peter said. "He doesn't know yet… But he'll put two and two together when he finds his omega wife in bed with his son, right, Mama?"
He looked up coquettishly at the omega and the brief flash of heat he saw in Tony's eyes told him that the omega was right on board.
---
It had started simply enough.
A simple mistake.
Tony had been holding Peter's arm and had stopped to coo at the tiny baby clothes in the shop window. Peter had made sure to hold onto his mate, knowing that if he let go that Tony would simply walk in and buy the entire store on a whim.
"Oh, that's so sweet," a passing omega commented. A stroller stopped beside them, a sleeping pup inside. The stranger gave them a knowing smile and Peter flushed.
Other omegas seemed to just know when another omega was pregnant. Not that it wasn't obvious, with Tony absentmindedly rubbing the small baby bump he had and Peter preening in smug satisfaction beside him.
"How far along are you?" The omega stranger asked Tony, smiling.
"Three months!" Tony told her proudly. As a male omega, they showed much earlier. Peter had been amazed.
The stranger turned to Peter then and honestly, Peter hadn't known what to expect.
Skepticism? Peter was a lot younger and looked like it when compared to his omega mate.
Whatever it was, Peter was prepared.
"And I'm sure big brother is just as excited?" The omega lady asked and Peter's world stopped.
Brother?!
---
Tony had teased him and Peter had endured it with stammers and flushed cheeks. It was the first time they had been mistaken for parent and child. But despite it being the first, it wasn't the last. It didn't matter that Tony Stark was a well known multi-billionaire that had recently been taken off the market. All people saw was that he was an older omega and that Peter was a younger alpha.
Peter's alpha pheromones were even stronger than any other. Since he was newly coming into his alphaness, his pheromones were thick and potent. Anyone giving him a sniff would think he was a newly presented alpha with how the scent of arousal and desperate horniess was constantly clinging to him.
He blamed Tony for being so fuckable. he blamed Tony for making him this way, for studding him from a normal omega with a healthy sex drive into a knothead of an alpha who was shameless in fucking his omega. And God, he needed it so often once the studding was complete. He always needed his new alpha dick wet and dripping from being in his omega mate.
They were both often drenched in each other's scent, as they should be for a newly mated couple with a healthy sex life. It was just that… the age gap thing… People got the wrong idea. His scent was thick on his omega mate, but others passed it off as a needy child smothering their omega parent in their alpha scent.
Clearly, clearly, they were parent and child.
Tony never corrected them and Peter… went along with it.
It was as if the universe had set out to tease him but the mistake was made often.
They were mistaken for parent and child again and again. And the thought made its way into Peter's brain and eventually… it made its way into their bedroom.
In this scene of theirs… They were Mama and baby boy. Peter was Tony's much loved alpha son and in their little scenes, Tony was indulgent and sometimes reluctant but he always helped his son with his problems. He couldn't deny his son, especially when said something had just gone through a grueling transformation from omega to alpha.
Just like in reality, Tony's baby alpha was in constant need of regulating… things… In handling the influx of instincts and possessiveness. Peter, as Tony's baby boy, had so many needs and Mama never failed to satisfy them.
And right now, Peter was desperately in need. Especially when Tony murmured out a breathy, "Baby boy…"
"Mama," Peter murmured, his hands drifting scandalously to his omega Mama's hips.
Tony squirmed beneath him and even more so when Peter maneuvered one of his legs to wrap around the alpha's hip.
"Pete, baby," Tony groaned, "don't say that– this pup… can't be yours, sweetheart… I'm your Mama, why would you–"
A press of his teeth against Tony's sensitive nipple had the omega squeaking. One of his hands escaped Peter's hold but instead of shoving Peter off, Tony grabbed the base of his hair. Fingers dug in as his back arched, pushing more of his tit into Peter's warm mouth.
"Fucked– mm– fucked a pup into you," Peter said. His words were muffled but Tony still got the message. His grip on Peter's hair tightened and tingles of pain started to radiate from there. It still felt good, everything Tony did to him felt good.
"Shh, baby, don't talk nonsense," Tony panted. "Just drink your milk and finish before your dad comes home."
Again. Tony must really be trying to rile him up with the thought of another alpha taking what belonged to Peter.
Peter wouldn't stand for it, Tony was his. His omega, his Mama.
With a growl, Peter reared up. Before his Mama could do more than gasp at the cold taking Peter's place, the alpha had his hands at the buckle of Tony's pants.
"Peter!" Tony protested but those protests were halfhearted, his one free hand easily being batted away.
Peter divested his Mama of his belt and before Tony could act, he had the length of leather tying the omega's wrists together and secured to the top of the bed frame.
Startled, Tony gave his bonds a shake and Peter hid a smile at the rattle it made as it remained secured. His Mama wasn't going anywhere.
He rose up on his knees and caught Tony's attention. His sweats were shoved down to his hips and with it, his alpha cock sprang out.
Tony's milk had helped nourish this body when he was in the process of studding. He had filled out some but compared to other alphas, he was still pretty lithe in stature.
His cock, though, was all alpha. It was like he was born to be this, to be an alpha more than willing to breed up the omega trembling beneath him. To be everything that his Mama needed. He was made for his Mama, and his cock ached to return to the familiar warmth of his Mama's body.
"Mama," Peter murmured as he started to stroke his cock. His hand went from root to tip, catching the thick drops of cum at the head and spreading it out over the generous length of his erection. "Look what you did to me, Mama. I'm so hard… Won't you help me, Mama?"
Tony's mouth dropped open a little and there was a hazy sheen to his eyes as he followed the smooth motion of Peter's hand. There was a hunger in his gaze that had Peter's cock grow even harder, thickening up to full mast.
"This wasn't… Baby, when you said you wanted to be an alpha, this wasn't what I had in mind," Tony murmured coquettishly. "You'd do this to your own Mama? Not my sweet alpha boy… He wouldn't…"
Peter sighed as he squeezed his alpha cock, barely able to keep his eyes open when it twitched hard in his hands. Another thick drop threatened to drip from his slit. He let it and it splattered down over his omega's swelling belly.
"Mama," Peter said patiently, "Dad wasn't satisfying you."
His mind raced to come up with the fake situations he needed for this.
"I could hear you in my room…" Peter said, still stroking his cock. He was getting harder and harder just thinking about it, his sweet omega being ravished in the room next door. It made fire flare in the pit of his stomach. "He wasn't satisfying you, Mama… But I know I can. I was made for you…"
Tony's lips trembled, caught between reluctance and the need to help his baby boy. A discrete check informed Peter that Tony's cocklet was tenting his pants.
"Mama… I can't take it anymore," Peter groaned out. "Please, Mama, can't I…?"
Tony's eyes remained fixed on Peter's alpha cock and then with a resigned sigh, he closed his eyes. His legs inched apart, spreading open for his needy alpha son.
"Okay, baby, okay… Take what you need," Tony allowed, a mother spoiling their needy child.
Peter purred but he didn't go for the prize Tony was offering him.
Instead, he shuffled himself forward on his knees and put himself in the place he wanted to. He kept his weight off the omega but his cock… His cock fit right between Tony's small chest.
At the unexpected touch, Tony's breath stuttered in his chest and his eyes flew open. He almost went cross-eyed trying to look at Peter's cock rubbing between the shallow valley between his pecs.
"Mm…" Peter moaned as he balanced himself and began rutting his cock between his omega mama's tits.
"Baby, I thought you were going to…" Tony gasped before falling silent.
"Stick it in you?" Peter panted as he looked down and into Tony's eyes. "I still can, Mama… But wanted to do this… Wanted Mama's tits first. You said I could take what I need, right, Mom? I need this…"
Tony was quiet for a while after that. Peter didn't pay it any mind, caught up in the sight of his thick alpha cock surrounded by the softness of his omega's tits. His precum smeared messy and thick between the omega's tits and every pass Peter's cock made between that space left it messier than before.
"Peter, untie me," Tony mumbled out.
Peter looked up to see his Mama wiggling his hands about, the leather still keeping him bound.
"Why?" Peter questioned. His hips continued their smooth roll, dragging his cock over soft skin.
"I…" His Mama's face was already flushed but whatever thought he had in his pretty little head made the pink in his cheeks deepen. "My chest… isn't big enough for you to… feel good…"
Peter frowned and looked down and yes, his Mama was right. Omega males didn't develop large chests, only a modest handful. Peter hadn't minded because it was Tony but the way Peter was fucking Tony's chest only had the omega's tits brushing against the sides of his cock.
"Are you offering to help, Mama?" Peter asked, wondering if Tony wanted to participate more than being a helpless mama enduring his son's inappropriate attention.
"You said this is what you wanted…" Tony murmured, eyes dropping. "If Mama helps you… It'll be enough, right? If I can help, then maybe we can finish before your father gets home…"
The flare of possessiveness that speared through Peter left him almost breathless. When Tony raised his eyes again, Peter knew what he wanted to do.
"Okay, Mama, if you can make me come before dad gets home…" Peter offered in consideration.
Tony gave a nod and Peter released his hands, easy as that.
He watched as Tony glanced at him before his eyes dropped to the task at hand.
Peter's abdominal muscles trembled as Tony placed his hands on either side of his milky tits. When he pushed them together, it still wasn't enough to completely engulf Peter's cock in a satisfying mimicry of a sleeve but the pressure, the warmth… the friction when Peter gave a curious thrust…
"Ah, Mama," Peter moaned as he started to thrust into the warmth of his Mama's tits. "it feels better, thank you, Mama… Mama's tits feel so good…"
Thrust… thrust… The motion of his hips became forceful and made the bed creak more loudly.
Peter could really lose himself to this. The softness of his omega's chest, the friction surrounding his needy cock…
Could he come like this…? He peered down at his omega and found Tony completely focused on his task of pleasuring his baby alpha with just his tits.
"That's it, baby alpha," Tony muttered under his breath, more focused on making sure he could cover as much of Peter's cock.
It was probably a harder task than it looked.
Peter's thrusting was jostling the omega on the bed. On top of that, Peter's abundant precum made it messy and slippery. And Tony's milk was still coming, especially with the added pressure against his chest. Drops of milk were slipping down his nipples and either spilling onto his fingers or adding to the mess where Peter's cock was fucking back and forth.
Messy and wet, with Tony's breathless encouragement… Peter could surely come like this.
Instead, he punched his Mama's nipples between his fingers and gave them a tug.
"Ah!" The surprise and shock of pain and pleasure in Tony's voice almost made Peter come right there. "What are you–?!"
"Need more, Mama," Peter told him while also thinking, you need more. He tugged on Tony's sore nipples, pulling them closer to the center above his cock.
"Baby…" Tony's voice trembled, "It… it hurts…"
But the pleasure in his voice betrayed the lie for what it was.
"Just a little more, Mama…" Peter promised, "Just a little more…"
Tony allowed it with a few breathless gasps. His fingers dug into the soft flesh of his tits, trembling hands trying to maintain the shape and tightness of Peter's current fucktoy.
"Tell me to come, Mama…" Peter begged when the pleasure was reaching a peak inside him. More milk was spilling readily and adding to the wet creamy mess that Peter was fucking through.
"Oh… Oh fuck, Pete…" Tony moaned, wiggling impatiently underneath him. "Come, already… Just come…"
"Mm… okay, Mama…" Peter gasped as he finally let go.
His knot popped, the massive ball at the base inflating and pressing against the bottom of Tony's tits. He tried shoving his hips forward as though knotting Tony's pussy.
There wasn't any space though so there was a prickle of pain as his knot was left alone. He barely noticed it before his orgasm swept through him.
Cum spurted out of his heavy cock. He could feel the intensity of it as his cock pulsed and twitched in its soft little home. Then he saw it as it spilled out in thick ropes, shooting so far that it splattered on Tony's collarbones and his face.
It was so much but Peter only groaned as it continued to spill out. When his cock wasn't as sensitive, he managed a few desperate twitches, his Mama's milk messy hand helping him out and squeezing his knot. Milking him…
A few leftover spurts of cum dribbled from where his cockhead peaked out from where it was smothered in Tony's tits. Another long thrust had Peter's cock dragging the mess of his cum and adding it to the mess between Tony's tits.
Milk and cum.
With a groan, his Mama finally released his poor breasts and Peter sighed in contentment. He moved down so that he could lean over his Mama and drag his tongue through their combined mess. The saltiness of his cum and the sweet creamy taste of his Mama's milk… The taste of them was delicious and only made Peter's mouth fill with more spit even as he swallowed it down.
Tony's hands carded through his hair, making a mess there too but Peter didn't care.
"Are we done, baby boy?" Tony's voice called Peter from his mission of licking up every drop of the mess he made.
Tony expected the scene to end… And sometimes, it was like this. Sometimes, Tony got such a high from their scene that he could easily rub one out, or Peter could easily suck him off. They'd call it a day and share an intimate shower as two people in love.
Mama and Baby boy can take a test until next time.
Instead, Peter cuddled up next to Tony, and his hips hesitantly pressed against the omega's.
"Mama…"
Peter wasn't done. Baby boy wasn't done with Mama yet and next to him, there was a sharp inhale as Tony got the message.
"Baby boy…"
