Steve cried out into the pillow, white-hot pain tearing him open. Gasping as his daddy's slick length was forced into him, coring him open. Bucky's dick settled itself into his gut, hot and thick and long and too much .
"It hurt, baby? I know, I know it hurts, but you're doing it for daddy, okay? Doing it for me," Bucky's voice was encouraging above him, "That's all that matters."
"Y-yeah, yeah, okay..." he whimpered. Steve buried his face in the white sheets, his eyes screwing up and tears soaking into the thin fabric. It was for daddy . He could do this. He would do anything for his daddy. Bucky's weight pinned him down on his stomach, lying prone on their bed - it felt like Bucky's cock went straight through him into the mattress. Bulging his belly.
Bucky drew out of Steve's hole, the muscle closing up again when it withdrew and trying to heal up already. His hole twitched in agony. Sharp pricks from being opened too quickly, forced open and torn. It tensed when the head of his daddy's fat head pressed against it again, anticipating the pain coming.
"There we go, a lil' deeper now..." His daddy cooed, soft and sweet, and then drove into him anyway, a slow and inescapable push. Steve's hole giving in, like always. Never keeping his daddy out of what he rightfully owned. "Stevie-baby, a little deeper for me— ohh, oh fuck. "
Steve's breath hitches, the pain overflowing and taking over him, hole hot and throbbing as his daddy sinks in to the hilt, daddy's hips pressing Steve into the mattress. Small jerks and thrusts of his hips overwhelm Steve with agony every time. It's just too big . His daddy's groans and the wet sounds of each movement echo through their bedroom. The soft light drifting through the curtains doesn't make it through Steve's eyelids, everything black except for the white-hot sparking through his body. His muscles ache from the tension, keeping him taut as a drawn bow.
"I wanna be your good boy... I wanna be good, please daddy?" He whispers. He feels small and used. Nothing but his daddy's toy, his treasure, his boy. Completely and utterly his . His to take care of, and abuse, and use for his own pleasure. Nothing matters outside their small bubble of peace.
"God, that feels good." Bucky's breath is harsh and panting. One hand lifts off of Steve's hip and he realises why a second later, jerking at the shock of cold lube drizzled directly over his hole. Sloppy and wet. Steve can feel those eyes focused in, watching the slick slide of his fat girth in his baby's hole. Steve's own cock is limp from the pain, given in, tucked down between his legs. Exposed for Bucky's gaze.
His daddy grunts in effort, in pleasure, and even though Steve's not hard, he is always so desperate for his daddy that it doesn't matter.
"Oh my god, ohmygod ohmygod," Steve breathed. "Daddy, daddy, daddy. "
"I like when you call me daddy while I fuck your tight little hole," Bucky drops down and presses a kiss to the back of his neck. Turns Steve's head and presses a kiss to the tears trailing down his face. It's slick in his hole but it's not easy at all, Bucky forcing himself in every time, making room inside for his girth, pushing in slow and aching. Opening Steve up again and again as the serum tries to close his hole and keep the ring of muscle closed. Tears soak the pillowcase. "That's it, baby, keep crying for me. Love seeing those big blue eyes shine with tears, swear it's just the prettiest thing."
"God, it h-hurts so bad," Steve sobs out the words, small quick breaths interrupting his words. "Am I being g-good, daddy? I w-wanna be good!"
"You are, that's right, that's so fucking hot. Goddamn. Letting daddy fuck you wide open. Daddy couldn't get this from anyone else, could only get it from his good boy. Only his baby boy would let daddy fuck him without prep, huh? My good boy's just a gorgeous little whore for daddy's cock, isn't he?"
The sweet words and the thick girth in his ass make Steve cry harder. He's being good. It hurts so bad. But this is what his daddy wants, so Steve takes it. His body surrenders, shivering under Bucky. Sometimes he thinks he would shake apart, into a thousand brittle shards of Steve Rogers, if Bucky wasn't around to hold him together. Bucky cracks him open, bares his heart and lungs and brain, exposes Steve for his eyes only. Makes him vulnerable in a way nobody else can. Breaks him down, but always brings him back together. Shatters him again and again to keep Steve Rogers alive and not be subsumed by Captain America.
Fresh tears bead in his eyes. His daddy's so cruel but Steve loves it. He gasps at a new wave of pain, body falling limp and loose finally. Giving in. Nothing but a slick, soft hole to be played with. His dick is soft and Bucky's too focused on chasing his own bliss to work Steve to a prostate orgasm, but Steve doesn't care. It's not about him. It's about his daddy. His daddy's pleasure.
"Best hole I ever fucked. My precious lil' slut, crying on Daddy's fat cock."
"Daddeey ," Endorphins flood his brain and he sinks deeper, words slurring. "Daddy, it's so big, ohh fuck daddy, please, please!" Steve's whining, he's begging, but he doesn't care. His daddy is fucking him rough and deep, and every time he is shoving in hard but drawing out slowly and it's breaking him. Pulling out slow enough for Steve's hole to grow tight. Fucking in brutally like he's coring him open for the first time. Invading his body.
"You want daddy to cum? Is that it, sweetheart?"
"Please please daddy!"
That's what he wants. He didn't even know before his daddy told him. Bucky pants heavily above Steve, drilling deeply into his boy. "You're such a good fucking boy, the best boy, god, nobody else could love me like you do, y'know. Taking my cock, crying from the pain and still begging for more. Fuck, I love you, sweetheart. So good to me."
Harsh thrusts punch deep into Steve's gut and he gasps in time as Bucky winds toward his orgasm. Like he's shoving Steve's organs out of the way. It's bruising.
"Good fuckin' boy. Precious. Sweetest fucking thing I ever saw," Bucky's accent is thick in his voice. He sounds like home. He grunts as he buries himself as far as he can into Steve and Steve cries out from the pain. That tips Bucky over the edge and he runs his mouth, "Fuck, take it, good boy, take my cock," as he cums deep inside Steve.
Liquid heat fills him and Bucky collapses on top of Steve without pulling out, drawing an oomph from him as Bucky's weight drops straight down. His back is blanketed by Bucky's bare skin, hot everywhere except for the chill of his metal shoulder. The only part of the arm touching him that's not warmed by body heat like the rest of it. Steve cracks an eye open, admiring the sunlight gleaming against the hand by his head.
"Goddamn, Rogers, you're something special," Bucky mutters into Steve's neck, rolling over and curling up around him. Steve in turn tucks himself into Bucky's arms, wrapping them around his body. Feeling small and safe. Like he was before the war.
"Love you too, Barnes." Steve's still floating, soft and pliable in Bucky's hand, malleable to his voice. The sting in his rim fades even as he speaks and Steve clutches the dog tags around his neck, the edges dulled by decades of wear but still digging into his palm. Bucky's claim on him, indisputably there. He'll always have Bucky's name, even if his body refuses to keep his marks.
