Honestly?
Bucky doesn’t know why the idea of getting banged by three massive hunks that call themselves men hadn’t appealed to him before. Apparently he has a few mind readers in close proximity- Because getting home and walking into his and Steve’s shared bedroom and seeing Thor and M’baku casually sitting with their tongues in each other’s throats and Steve watching them with a hand down his pants was not the first thing he had expected to see.
Then again, that fact had certainly not stopped Bucky from immediately getting hard from the sight, nor had it stopped Thor or M’baku from heating up their semi-public make out session by groping at each other over their clothes.
Steve had claimed it was his anniversary gift- and fuck if Bucky didn’t appreciate the hell out of that. His already huge super-soldier boyfriend had hooked him up with two even huger guys who seemed just as eager to get their dicks out as Bucky was, and not one of them made any attempt to hide it as they eyed Bucky with dark looks. Overwhelming was definitely the perfect word to describe Bucky’s situation, but Steve had helped him get started by diving in head first and grabbing M’baku’s head, pressing their lips together in a kiss that quickly got the both of them grappling with each other’s clothes and tearing them off.
They’d done the same to Bucky after that, stripping him quickly with some offhanded comment about the excessive amount of clothes he wears from M’baku. Though, Bucky was too distracted by the size of that goddamned Wakandan’s dick hanging heavily between his legs, which got him salivating because he knew that the first thing he was gonna do was get his mouth around it as if he was born to do it.
Thor hadn’t joined the party until Bucky was dumped on all fours on the bed and being fed M’baku’s dick, making the mattress dip from where he so eagerly knelt beside Steve. Bucky wished he could see the two of them because the noises behind him were just vulgar after a few seconds. Steve had his hand tightly clasped on Bucky’s hip, squeezing occasionally and making Bucky moan around M’baku as he took him deeper into his throat. M’baku himself seemed to be enjoying this, snaking a hand around Bucky’s neck and pushing his head down and letting out a deep groan as Bucky’s nose pressed against the wiry curls at the base of his dick.
“Damn it, Rogers. He’s- ungh - he’s good-” M’baku tries to say, but Bucky is too busy trying to distract him but swirling his tongue around the head of his cock and tasting the salty pre-come dripping from it before he goes back to sucking.
Then he feels two lubed up fingers rubbing at his hole and he knows it’s Steve prepping him for what he hopes to be Thor fucking him into incoherency. They push into him with little resistance and then two become three and then four, and Bucky is moaning around M’baku again as those fingers curl to graze his prostate and he hears Thor’s deep rumbling laugh from behind him.
“The little one is so easy to please, yes?” He says, letting his big hands feel up Bucky’s ass as he talks. Bucky whines at the thought of being called ‘little’. He knows he’s certainly not little, but by the way Thor’s hands fit around his waist with ease it sure does seem so.
“It’s not gonna take much to make you come tonight, is it, baby?” Steve asks Bucky, pulling out his fingers as Bucky shakes his head as much as he can with his mouth full. Then there’s a great deal of shuffling behind him and Bucky is about to pull off of M’baku to ask what’s happening when the Wakandan yanks his head back down and holds him there, letting himself feel the warm softness of Bucky’s throat before he lets him off with a wet gasp.
Bucky wipes his mouth to answer when Steve asks, “Which one of us do you want, doll?”
“Thor. Please, I need it,” Bucky rasps, throat still sore from deepthroating M’baku. Steve grins and lets Thor get settled behind his boyfriend, and that's when Bucky starts to panic because the fucking size of that man is devastating and would definitely split him in half. “He’s big, huh?” Steve says, closing his hand around Thor and stroking him slowly. Even his hand can’t fully wrap around the girth of him and it sends a spiky shiver up Bucky’s arched spine.
“Jesus,” Steve breathes, helping to line Thor up with Bucky’s hole. M’baku is still holding the side of his face with one hand and has the other on his cock, stroking it slowly so the little beads of pre-come slip down the length like perspiration. Bucky isn’t ashamed to admit he’s a cockslut, because he really can’t have gone this long without M’baku’s in his mouth and tries to lick at the tip a little even when he can’t reach it.
“Easy there, Buck. You might wanna brace yourself,” Steve then lets go of Thor's cock and he tries to get the head past Bucky’s rim. When there’s minimal struggle, Bucky starts to calm down thinking, this’ll be fine!
It won’t, in fact, be fine.
He already feels stretched, but when Thor shifts the tiniest bit and pushes in at the same time? That’s when Bucky really feels the stretch and bunches the bedsheets in his fists. Thor takes it slow, dangerously slow, but Bucky knows it’s because he wants him to adjust to the god’s unbelievable girth before he tries to make him take any more. He lets himself succumb to the burn, feeling it quickly simmer down into that underlying layer of pleasure the more Thor pushes into him, and then he’s feeling the tip of his cock nearly up to his belly when Thor’s pelvis hits his ass. Thor never stops running his fingers all over the hot skin of Bucky’s back as he eases in, and that, Bucky thinks, is the best part.
“Fuuck,” Bucky lets out a drawn out groan and lets his head drop, feeling sweat trickling from his hair and onto his forehead as his body gets acquainted with Thor sitting hot and heavy in his ass. He’s full, too full, and yet he can’t seem to get enough of this and pushes eagerly back onto Thor, forcing him to graze Bucky’s prostate and making him groan with oversensitivity.
“Is he okay?” He hears him ask Steve, then his boyfriend’s hands are stroking soothingly along the arch of his back and the curve of his ass and the dip of his hips and he’s telling Thor, “he just needs a little minute.”
He whimpers and M’baku shifts so he’s at eye level to Bucky, then he leans in and starts kissing the brunet all messy and it’s everything Bucky has not to squirm and spear himself back onto Thor’s dick. M’baku’s mouth is hot and his tongue is wet as it slips over Bucky’s, making his skin prickle and his thighs tremble, and that’s what Thor takes as a sign to actually pull back the tiniest bit and push back in again.
“ Oh,” Bucky moans, pulling away from M’baku as he feels his prostate being grazed again. He realises that because Thor’s so big, he’s gonna be assaulting Bucky’s sweet spot every fucking time. He’s not even hitting it - there’s only the continuous pulsing pressure on that spot that has Bucky groaning grasping the bedsheets.
“He’s alright?” Thor asks again, putting his hands back on Bucky's waist as he nods frantically. “Mhm,” Bucky is way past words now, so when he hears Steve speak for him, he can only moan again in agreement.
“I think he’s ready to take it all, Thor. You can go for it now, go on- fuck him .”
And, Bucky be damned, that man does not waste any time, shoving Bucky’s legs apart and burying his cock deep in the guy’s ass in short sharp thrusts. Even that is enough and Bucky’s own unattended dick blurts out a string of wet that dirties up the sheets. Bucky can’t bring himself to care, though, because he’s already fuck-drunk and panting as Thor starts fucking him in earnest.
Then Bucky becomes aware of M’baku still kneeling in front of his face with his hand fisting his cock and suddenly Bucky is hungry again. He stares up at the man until he looks down with a dark look in his eye, then Bucky sticks his tongue out and M’baku slaps the tip of his cock on it a few times before pushing back into the warm wetness of Bucky’s mouth.
“Ah, fuck,” He groans out, quickly fisting a hand in Bucky’s hair and pulling him down further. Bucky feels that slick slide of M’baku breaking past his gag reflex, letting him fuck his mouth as his body shakes and muffled sounds are being fucked out of him every goddamn thrust.
“Think this cock needs a little attention, hmm?” Steve says, as if it’s not even a question that, yes , Bucky does need something to relieve the pressure on his cock or he might actually burst. Lucky for him, Steve has always been hungry for sucking Bucky off, and he makes quick work of stroking him fast and hard before he’s laying on his back with his legs swinging off the side of the bed, mouth licking at Bucky and his hand tugging at his own leaking dick.
Thor fucks him impossibly harder, now. He lets out deep groans and grunts and tightens his bruising grip on Bucky’s waist every time the brunet clenches hard on his cock. Steve seems to notice what really sets Bucky off, swirling his tongue around the head of his boyfriend’s cock with that skillful tongue of his just as Thor hits his prostate dead-on and Bucky loses himself to the fullness and the burning and the stretch and he’s coming all over Steve’s open mouth better than he has in weeks.
Steve lets out a pleased laugh underneath him and Bucky hears more sucking sounds and it just has to be Steve licking up his come as if it’s his last meal. Thor’s grunts get louder and Bucky feels his cock swelling up inside him. He’s quickly pulling out, leaving Bucky feeling empty and his hole gaping, as he gets a hand on his cock and spends himself all over Bucky’s back. It’s so much. Bucky feels his eyes roll back into his head when Thor finally sighs behind him, obviously done on his end because he kneels down and starts soothingly rubbing Bucky’s back while helping Steve out with his orgasm.
Bucky keeps letting M’baku fuck his mouth, relishing in the slippery slide of his cock between his swollen lips and the pulsing he feels that can only mean he’s getting close to finishing. Bucky taps his hand and feels the pressure on his head be released.
“Wanna come in my mouth?” He asks, grinning up at M’baku who by now has lust blown eyes and can only nod dumbly as Bucky gets both hands on the parts of his cock his mouth isn’t able to fit over. Then he doubles down on his efforts and probably overwhelms M’baku by milking his cock and sucking hard at the same time because he instantly groans and Bucky feels hot come streaking down his throat.
“Jesus Christ.” He’s mumbling, then lifting Bucky up by his hair again to kiss him. Bucky wonders if he can taste himself on his tongue. “How was that?” Bucky breathlessly asks when their lips part. M’baku just gives him a look that says, ‘how do you think?’. Bucky grins.
“Come on, doll. Let’s get you cleaned up.” Steve is saying, gently rolling him over to his side and being careful not to hurt him. Steve knows he’s probably sore and lets him lay there while he wipes him up and covers him with the blankets. “You alright, baby? Need anything?” Steve asks him once they’re all tucked up under the covers. Thor and M’baku lie next to them, cuddling each other as they fall into easy-coming sleep.
“M’good, Stevie.” Bucky says tiredly, stretching his arms around his boyfriend and closing his eyes after burying his face in the crook of his neck. “Happy Anniversary.”
