Bucky had never brought up wanting kids and you'd sort of assumed that he didn't want them - with a background like his, and the hardened man that he's (when he's not feeling poorly, and trying to be close to you 24/7) it would be totally understandable if he didn't want to bring a whole new human into the world. Maybe the trauma just ruled that out. Even he had never really consciously wanted children.
That was until you were pinned below him, with your pretty legs hoisted up to your chest and your hands wrapped around his body, digging into his back, ndwarfed by the size of him. Bucky likes to fuck you deep — he can go fast or slow, he doesn't mind, but he needs to make sure that ur cute little cunt is taking all of him. He'd never wanted children, but the sight of you on his dick, little gasps slipping from those lips... you'd look so pretty carrying his babies.
"I want t'get you pregnant," he grunts, a metal arm moving up to the side of your head to support him as he fucks into you. You've been with him before, but you never get used to the sheer power of him, your lips forming a little "O" as you struggle to form your words.
"W-Why but I- Buck-" you whine. You only wish he'd slow down to let you speak, but your flushed mumbling just encourages him, his fat tip making a bulge in your stomach.
"Can't talk, doll? Is my pretty girl struggling.?" A little, nasty glint in his eyes tells you just how much he's enjoying seeing you struggle like this.
"Will you le'me give you a baby and make me a real daddy?" he groans, as he feels ur pussy clench around him. Faint words try to escape your lips but it's futile, and your boyfriend grins as he watches you splutter and nod for him. His strokes only become faster, deeper and sloppy causing your toes to curl when he touches parts so deep inside of you that you didn't think that was possible. He let out little grunts of appreciation as your walls gripped him tight.
"Fuck.. can't wait suck ur tits full of milk" he groaned, his brow furrowing, "y'feel so good.... fuck...." This man makes sure to take his time (and savour the view) and when he finally shoots his cum inside of you, he stays in there for a little while — just to make sure nothing can escape and undo all his hard work. If it did, it wouldn't matter, he'd just fuck it right back into you.
"Such a good girl... takin' my kids so well." he whispers gruffly into your ear, his large hands stroking your back gently as you catch your breath.
"You'll look so pretty with my babies, babydoll" he kisses your forehead softly.
