Peter squealing and making short aborted screams as he's manhandled and held tight with two large hands that could wrap around his pretty little waist if they wanted, as he's practically used as a doll, being bounced up and down with hard thrusts that echo through the living room with a mixture of wet slapping skin and Steve's deep growls.
But when the old man 'tires', Bucky steps up to grab the boy from under his knees and holds him up against his chest, legs splayed wide and obscene with his little cock hard and leaking, already colored and dried with the only orgasm he was allowed an hour ago. His hole is red as cherry, gaping and far too empty for his liking and he whines, loud.
Bucky chuckles in his ear, making him shiver, "Always so desperate for it. Aren't you baby doll?" and it sounds sweet but the growl in his growl suggests otherwise. Standing down, Steve teases his wet cock across Peter's needy hole, purposely dragging the fat head along the open rim to tease, smirking at the breathy moans he got for it.
"Bucky asked you a question, angel. He expects an answer." and Steve is enjoying this way to much, stroking his cock with excess lube and Peters saliva from before.
Head dropping back against Bucky's shoulder, he finally whimpers, "Need your cock, Daddy." his back arches the best he can in the Winter Soldiers hold when Steve pushes in the tip then out again, "Please!" fresh tears are in his eyes, his need to cum rising in his gut, "always need my daddies-" he bites his lip, but Bucky squeezes his thighs for him continue and he knows what he needs to say but it always made him embarrassed. But when Steve just keeps fucking teasing his twitching and greedy hole, he relents with a pitiful wail, "Fuck my pussy, Captain! Ple-!"
Peter's scream can be heard through the entire apartment building, followed by his sobbing mantra of "Thank you daddy,"
