Mine.
Bucky wanted to kill her.
He had loved all of Steve's other friends, Sam, was sweet and kind and had pulled him into a hug when he met him, and had been bantering happily with Steve all night . Bruce was calm and friendly, indulging Bucky by answering all his questions about his and Tony's work.
The only one he didn't like was Sharon.
She wouldn't take her hands off Steve, she kept touching his bicep and making excuses to squeeze past him, pressing her ass against him or brushing his arm with her tits.
She'd made several comments about Bucky being a “little… plainer” than she expected and asked Steve if he regretted Bucky IN FRONT of the omega.
They had been at the dinner party for a while now.
They had moved to the sitting room after dinner, everyone scattered on different couches, Loki and Thor curled up in the corner of one couch, Loki's legs in Thor's lap. Peter and Clint were engaged in a rather aggressive game of ping pong with Sam and Natasha, everyone getting increasingly competitive as the match went on.
Steve was in an armchair with bucky on his lap,both of them laughing with Tony and Bruce.
“Im so happy we all got perfect omegas” Steve grinned, the alcohol making his words loose and joyful “I mean, look at them!”
Tony threw his head back with laughter “I'll drink to that!” He said clinking his glass against Steve's.
Steve turned to him with a grin. “Kiss me” he said lazily affectionate as he ran a hand over Bucky's side. Bucky lent down to do so, pressing a quick soft kiss to Steve's lips.
“Can you guys stop basically fucking on Tony's furniture” Sharon said sharply, Tony and Steve laughed, taking it as a joke, but Bucky looked over at her quizzically. Why was she being so mean?
“Never” Steve said grabbing the back of Bucky's neck “I couldn't keep my hands off this one if I tired”
Bucky giggled, throwing his head back and wiggling happily on Steve's lap, allowing the alpha to hold him even closer, a slip a hand into the slit of dress and hold his thigh, close to his ass, to hold him on his lap.
Sharon scoffed.
“Guys! I almost forgot!” Peter said, as usual he was a constant ball of energy and excitement “Bucky made his famous chocolate muffins! Does anyone want one?”
“Oh yes please!” Loki said perking up a little “Thor you must try one, they're absolutely delicious”
Thor grinned and nodded “If my omega says so I would love to try one of your delicious muffins Bucky”
The others added comments of agreement, Clint nodding after asking his “mama” if he could have a “Chocky muffin”. Bucky loved little Clint, and in the final year of the academy, they had all become 'big brothers’ to him.
“ okay! I'll just bring em through” he said, standing
Steve landed a solid slap to his ass as he walked away, making him squeak and turn to his alpha with a giggle.
“You're beautiful” Steve grinned
“You’re drunk” Bucky countered, but lent down to kiss him before Fetching the muffins, laying them out neatly on the tray he had brought and carrying them through into the living room, he passed them out, receiving compliments at the chocolaty goodness before picking one up for himself.
“Oh you're having one Bucky?” Sharon said looking confused
“Yes? They're my favourite” he said taking a bite.
“I thought omegas watched their weight?” She said looking at Buckys stomach and then back to his face, an evil smirk on her face.
Bucky wasn't going to let her win, instead putting himself back down in Steve's lap, snuggling close. “Alpha loves my tummy, don't you?” He said kissing Steve's jaw.
Steve who had been distracted by a conversation, turned to him and smiled. “I love your cute little flat tummy” Steve said running his hand over it with a smile “it's adorable, it's going to be even better when you start showing” he grinned.
“We don't even know if I'm pregnant yet” Bucky said looking directly at sharon, a little smirk on his face.
“If you're not, you will be soon” Steve whispered, quietly, just for Bucky to hear.
Bucky giggled “why don't we go upstairs and go make sure” he whispered into Steve's ear, running his and between them to subtly squeeze Steve's cock.
Steve growled and stood up, taking Bucky's hand and tugging him out of the room, Bucky pulled them up to the bathroom, giggling the entire time.
Steve slammed the door and Bucky jumped onto the counter, pulling his panties to the side and presenting his neck to his alpha.
Steve growled and swiftly approached him, wrapping a hand around his throat and unzipping his pants. “Such a slut for me huh? Can't get enough”
Bucky whined and pushed against the feeling of Steves hand around his throat, his eyes rolling back. “Only for you” he whispered grinning at Steve.
Steve pulled his dick out of his pants, lining up with Bucky's ass. After a few seconds of frustration, he tears Bucky's panties off and throws then aside, sliding home.
Bucky could get drunk off the feeling of Steve inside him, the feeling of his hands on his body, the little moans his alpha let's escape him as he thrusts inside of Bucky.
Steve is rolling his hips into Bucky, deep, heady and intoxicatingly passionate, when Bucky hears the bathroom door open.
Sharon takes a small step into the room before gasping silently and bringing her hand to her mouth.
Bucky grinns at her moaning loudly and deliberately. “Fuck alpha feel so good, promise you're mine forever?”
“I promise baby” he growled “you're mine and I'm yours, that's why you wear my mark baby” he said, moaning loudly and grabbing at bucky.
Bucky smirked, kissing Steve's neck and jaw, never taking his eyes off Sharon's. “Cum inside me” he said holding Steve's hand against the wall beside his head. “Please”
“Always” Steve moaned,
Sharon slowly took her eyes off Steve and tried to close the bathroom door quietly.
Bucky knew he wouldn't have issues with her again.
