Chapter Text
The first thing Tony notices when he steps through the door of his home is the sweet aroma of vanilla and white chocolate. The alpha’s nostrils flare and his slacks grow tight from the delicious scent. His omega was in heat.
Tony had gotten the call from Bucky during one of his board meetings. It pissed both the members and Pepper off, and he knows he’ll be hearing from her tomorrow, but his family came before anything else. Perhaps he should have explained why he was abandoning the meeting, but the only thing that mattered at the time was getting home.
The house is suspiciously quiet. Usually one of the pups was making noise or causing some kind of ruckus. The living room looks as if a tornado had blown through it; toys and books litter the usually tidy place. Bucky must be too busy with Steve to have cared about the appearance of their home.
Tony frowns to himself and makes his way toward the stairs, only to pause when two heads peek out from the top rail, two sets of eyes peering down at him.
“Come here, kiddos.” The two pups don’t even hesitate when their daddy calls them. Peter is the first to reach Tony, wrapping his arms around the alpha’s waist. Harley takes off running down the stairs to get his own greeting.
“You’re home!” Harley smiles and he tries to push his younger brother out of the way. Peter huffs and shoves Harley back, whining for his daddy’s attention.
“Pete, relax,” Tony chuckles and ruffles his son’s curly hair. “I can give both of you hugs.”
Peter’s smile returns and he wraps his arms around Tony again, purring softly. His pups weren’t usually this clingy. They enjoyed kisses and cuddles, but there were times when they wanted their own space. They were getting older and not needing their parents as much anymore. It hurt and made Tony wish that they would stay small forever, but he was a proud alpha and father nonetheless.
“Where’s Papa?” Tony asks, glancing up at the stairs, expecting to find the other alpha standing near the top.
“With Mommy,” Harley replies.
“Ah.” Tony nods, understanding the sudden clinginess now. Bucky was probably upstairs with Steve and trying to make him comfortable. Steve hasn’t had a heat in a few months. He got on suppressants a little after Peter was born. At the time they were content with just two pups, but then Steve wanted another and that’s when he decided to return to have heats.
Their mating never resulted in another pup. Tony blamed himself for all of the negative results Steve received. When Steve decided he wanted to try again, Tony suggested Bucky be the one to impregnate their omega. It only made sense.
“Mommy doesn’t feel good,” Peter says, his bottom lip jutting out and brown eyes shiny with tears.
“It’s that time of the month again,” Harley says with a roll of his eyes.
“Hey, knock it off,” Tony scolds. “Mommy suffers a lot. You could go through this when you’re older.”
“Unless I’m an alpha.” A cheeky grin breaks across Harley’s face. Tony is seconds away from grounding his son.
“Go play outside for a bit. I need to check on Mom.”
“Papa said Uncle Sam is coming,” Peter says.
Tony blows out a sigh of relief. “Thank God,” he mutters to himself. The pups were better off being somewhere else during Steve’s heat. They usually lasted three days, but it was an intense three days. He’d constantly need attention and for his alphas to look after him. And when he did go into a heat, Tony and Bucky’s ruts would sync up. Tony was getting older and his stamina levels weren’t what they used to be.
“Tony?” Bucky calls from somewhere above and Tony peers up, meeting blue eyes. “He needs you.”
Tony nods and makes sure the pups are distracted with a movie before making his way up the stairs. Bucky leads the way toward the master bedroom, and pushes the door open, releasing the strong pheremones Steve was giving off. Tony inhales the sweet aroma, his cock twitching in arousal.
But it’s the sight of his half-naked mate cozied up in a nest consisting of blankets and other articles of clothing that has Tony’s cock growing hard and the urge to mate more prominent. Steve’s bare upper-half is already glistening with sweat, the firm and tone muscles of his back flexing. Steve whines into the pillow while he grinds against the mattress, no doubt smearing his slick along the cotton sheets.
“He’s gotten worse,” Bucky says, snapping Tony from his trance. “I can feel my rut coming on, but I’m holding off until Sam picks up the kids.”
“Is he almost here?” Tony asks as he begins to shed his suit jacket and neatly fold it up.
“He said fifteen minutes. Do you mind staying with Steve while I get them ready?”
“Yeah of course. They miss their papa.”
Bucky smiles softly, then he glances over at Steve when the omega emits another whine. “He really wants you.”
Bucky leans down to kiss the top of Steve’s head, and whispers something to him before he leaves. Whatever he’s said has Steve lifting his head off the pillow and glancing over at Tony.
“Tony,” Steve pants heavily, and he grinds down against the bed. He releases another pitiful whine, pleading his alphas to help him. Tony is at his side in seconds, crawling into bed with him and pulling his mate close. Steve curls up with the alpha, burying his face into Tony’s neck an inhaling the musky scent. “Alpha,” Steve purrs and licks along the bond mark. “Missed you so much.”
“Yeah?” Tony peers down at Steve while he gently threads his fingers through his damp hair. “Bucky told me you were going into heat. You need your alphas, huh?”
“Mhm.” Steve nods and rubs himself along Tony’s thigh. The alpha’s breath hitches in his throat when he feels Steve’s hard cock against his leg. “Need you, Tony. Want your knot.”
“Honey, Bucky is going to mate with you this time, remember? Maybe we’ll get another cute blue-eyed pup. She’ll be fiesty like you,” Tony chuckles.
“Want you, Tony. Please?” Steve continues to rub along Tony’s leg, moaning softly from the delicious friction it’s created. Tony lets him do as he pleases, knowing how needy Steve became once his heat hit.
“Let me help you take off the edge, sweetheart.” Tony gently pushes his mate away, ignoring the sad whine Steve makes from the loss. Steve rolls over onto his back, one hand flying down to his crotch to palm at his aching cock. A wet spot is begining to form beneath him; the smell of slick penetrates the air.
“Tony, please?” Steve begs, bucking his hips in an attempt to get his alpha to touch him. Tony complies easily, and he positions himself between Steve’s spread legs, grinding down and rubbing their erections together. Steve moans and yanks Tony close, leaning up to lick and bite along the alpha’s neck. “Need you, Alpha. Need you to fuck me.”
A low rumble of approval vibrates through Tony’s chest. The plan was to have Bucky mate with Steve, but now Tony was considering a new plan. He wanted to be the one to put another pup in Steve’s belly.
“I got you,” Tony assures and he connects their lips in a heated kiss. Steve moans against Tony’s mouth, the sound sending jolts of pleasure through the alpha’s body. He loved the beautiful noises Steve made. He wanted to hear more of them.
Tony forces himself to break away so that he can work on shedding their clothes. He reaches for the band of Steve’s sweats and lowers them down his legs, not surprised to find that his mate has decided to forget underwear today. Tony can’t help but lick his lips at the sight of his mate’s beautiful cock. It was on the smaller side due to his omega status, but it was still perfect enough for Tony to play with.
“Fuck,” Steve curses and tips his head back when Tony touches him. The feel of his rough fingers is exquisite. He fears he might cum just from being touched. His belly coils tightly and his breathing picks up. He doesn’t want to cum yet.
“You gonna cum, baby?” Tony croons as he increases the pressure on Steve’s cock. Steve’s whole body shudders from the feeling, his cock twitching and leaking along Tony’s fingers. Tony can’t help himself and he ducks down to take Steve into his mouth.
Steve cries out and grips Tony’s head with both of his hands. “Yes! Tony, more. Please.”
Tony hums along Steve’s cock, the taste of his omega intoxicating. He pulls off and returns to stroking the heated flesh while he trails his other hand between Steve’s legs, gently fondling his balls and the senstive spot underneath them. Steve whines, his back arching off the bed when Tony teases his tight hole.
“Fuck, Steve, you’re so wet.” Tony moans at the amount of slick leaking from Steve’s hole. He runs a finger around the tight rim before dipping his finger inside and watching the way Steve swallows him in. “I can’t wait to bury my cock inside you. You want that? Want Alpha’s cock?”
Steve nods his head frantically, his hands reaching out for Tony and pulling him close. Tony allows Steve to bring him in and their lips meet again. With Steve distracted with the passionate kiss, Tony slides more of his finger inside Steve’s tight heat, and Steve moans, the sound swallowed up by Tony’s mouth.
Steve grips Tony tighter, blunt nails running down Tony’s back. He toys with the fabric of the soft button-down Tony had worn for his meeting, wanting the barrier out of the way so he can feel his alpha’s smooth skin.
Tony gets the message loud and clear and he pulls away to remove his shirt, taking his time and teasing the omega. Steve can’t hold back any longer and he stretches out a hand to feel Tony’s chest, running his fingers along tanned skin. His movement cease when he senses another presence in the room, and his eyes flicker behind Tony.
“Starting without me, doll.” Bucky’s husky voice fills Tony’s ears. He brushes his lips against the shell of Tony’s ear. Tony shudders and reaches behind for Bucky, feeling the other alpha pressed against him, his cock digging into the small of Tony’s back. Bucky’s mouth trails lower, pressing open-mouth kisses along Tony’s neck, teeth purposly grazing over the mark he had put there.
“Where’s the…where’s the pups?” Tony manages to get out.
“Sam just left with them. It’s just us,” Bucky replies, his hands coming to rest on Tony’s shoulders and he pushes the shirt down, trailing kisses along the exposed skin. “So sexy,” he murmurs, stealing a glance in Steve’s direction. “Both of you.”
“Bucky,” Steve breathes out, beckoning the alpha over. Bucky places one last kiss on Tony’s shoulder before moving toward his omega, ducking down to capture Steve’s lips in a heated kiss.
Tony watches while they make out and he reaches down for his cock, palming himself through his slacks. He moves off the bed to discard them, allowing Bucky to take his place and keep Steve busy. Tony turns away from the heated scene to work on opening his belt, only to snap his head up and spin around to face his mates when he hears Steve cry out. Bucky is between Steve’s spread legs, licking and slurping the slick that Steve produces. Bucky moans from the taste; he’ll never get tired of it.
Steve turns his head in Tony’s direction, whining softly to get his alpha’s attention. Tony works fast on removing the rest of his clothes, then once he’s completely bare, he moves toward Steve again, one hand fisting his cock. He joins his mates on the bed and kneels in front of Steve, leading his cock to the omega’s lips and smearing the wet head along them.
“Want my cock?” Tony smirks and Steve parts his lips to take Tony inside his mouth. Tony curses when Steve wraps his lips around him and begins to suck. He places a hand on the back of Steve’s head, bringing him closer until Steve gags. “Fuck, sweetheart,” Tony pants and affectionately strokes Steve’s face. “You’re so eager for me, huh?”
Steve nods, his eyes dark with arousal. Between his legs, Bucky is still teasing him, fucking him with both his tongue and fingers. Steve lets out another moan and Tony takes that as the opportunity to fuck his mouth. They fall into a steady rhythm; Tony fucks Steve’s mouth while Bucky works four of his fingers into him, making sure he’s properly stretched.
Steve whimpers and moans around Tony’s cock, sending pleasurble vibrations through him. The familiar heat in his belly returns and Steve cries out as he pulls off Tony’s cock and cums on Bucky’s mouth, slick gushing around Bucky’s fingers and wetting both the alpha and the sheets beneath him.
“Fuck, Stevie,” Bucky thrusts his fingers harder, his arousal dialing up as Steve squirts around his fingers.
Steve trembles from the orgasm and the sensitivity, his legs falling shut and forcing Bucky to stop. “N-No more. ‘M sensitive.”
“I know, doll,” Bucky says and scoots up to press a kiss to Steve’s lips, allowing the omega to taste his own slick. “You taste so good, Stevie. I could eat you out for hours. But I know you want to be fucked, huh?”
Steve nods and pulls Bucky back in for another kiss. Bucky indulges him for a while before pulling away and leaning back to rid himself from his clothes. Tony watches with interest as the other alpha undresses, his cock jumping in his hand from the sight. Both of his mates were so mesmerizing.
“You gonna stand there and watch or come fuck him?” Bucky teases with a smirk.
Not needing to be told twice, Tony positions himself between Steve’s legs, gently running his hands over Steve’s thighs. “You want me to fuck you?” he asks, voice rough with arousal. Steve whines and wraps his legs around Tony’s waist, urging him closer.
“Put a baby in him,” Bucky says as he strokes his cock. “I love it when he’s round and full of pups.”
Steve whines again. “Need you. Want your pups, Alpha.”
“I know,” Tonys says and leads his cock to Steve’s stretched hole, teasing the pink rim for a moment before slowly pushing in. Steve moans and grips Tony tighter, begging for his knot and pups. Tony thrusts forward until he’s buried deep inside the omega. “You feel so good, Steve. Does it feel good for you?”
“Yes!” Steve nods his head frantically, eyes fluttering and jaw slacking when Tony begins to rock his hips. “More. Please, Tony, I need more!”
“Fuck him hard,” Bucky says from his spot beside Steve. He’s working his cock in time with Tony’s thrusts.
Tony lifts Steve’s legs and places them over his shoulders, then he fucks him hard and fast. Steve screams and cries from the pleasure, his eyes rolling back into his head and drool running down the side of his mouth. He’s so lost in the pleasure that the words that spill out of his mouth are incoherent. All he cares about is getting fucked and bred.
“Fuck, fuck, fuck.” Tony chants when the base of cock begins to tingle, his knot forming to lock inside his needy omega. “Gonna…knot you so…good…fuck.”
Beside them Bucky grunts and moans as he fists his cock. Steve blindly reaches out for his other mate, needing to feel him as he comes undone. He moves Bucky’s hand out of the way and wraps his own around the alpha’s cock, stroking him fast, bringing him closer to his release. Bucky returns the favor by taking Steve’s cock and jerking him off.
“Cum, Steve. Cum all over my hand, all over his knot.”
Steve whimpers and clenches down on Tony’s cock, emitting a deep growl from the alpha. Tony fucks into him faster, his knot nearly formed. On the next thrust Tony forces his knot inside and Steve screams, his body growing taut and cock spilling over Bucky’s hand. Bucky curses and releases over Steve’s chest and face.
Tony keeps thrusting, fucking Steve with his knot. The omega clenches down on him again and Tony cums with a grunt, his cock pulsing with each spurt of cum he releases. Steve whimpers from the warmth of his alpha’s seed inside him.
“You did so good, Omega,” Tony praises as he continue to thrust softly into Steve. He leans down to capture Steve’s lips in a kiss, moaning when a bit of Bucky’s release touches his tongue.
Steve purrs from the praise and nuzzles Tony’s face. “Alpha…”
“I’m right here, sweetheart. We both are.”
A tired smile breaks across Steve’s face and his eyes flutter for a moment before falling shut. Tony kisses him again, then turns his head in Bucky’s direction, finding the other alpha spent and satisfied .
“You wanna go next?” Tony asks.
“Maybe. He might be out for a while though,” Bucky replies as he searches the room for a wash cloth. He disappears to the bathroom and comes out a minute later with two wet wash clothes. He gently scrubs along Steve’s face and chest.
Once Steve is cleaned up, Bucky lies down beside him and gently plays with the omega’s hair. “Do you think it worked?” he asks, peering over at Tony.
“I don’t know. There’s a reason why you mated with him first. I’m getting too old,” Tony grunts as he tries to maneuver him and Steve is a more comfortable postion until his knot goes down.
“It worked with Peter.”
“True, but that was luck. Maybe you should knot him next. Lord knows he’ll be begging for it.”
“Yeah.” Bucky smiles fondly down at Steve and presses a kiss to his head. “I love you, Stevie.”
It takes a few minutes for Tony’s knot to go down, then once he’s able to pull out, he rolls over and lies beside Steve. Both alpha’s cuddle their mate close, scenting and snuggling him. They both wonder if they’d have a new member to add to their family.
Only time would tell.
