Sam isn't ashamed to admit that he yelps as Bucky bounces him on his cock. Just the once, but it's sharp. It goes deeper than Sam's ever taken dick before. It's thicker, too, and that doesn't help matters. His mind is a litany of 'shit, shit, shit', because he's not sure he can ever be ready to take this, even if he were so inclined to give Bucky the time of day.

Sam glares over his shoulder, struggles against the hold Bucky has on him once more.

"No. Absolutely not - do not bounce me."

Sam shows his teeth. Useless, he knows, but the gesture of aggression makes him feel a little better about the fact that for the next two hours he's gonna get fucked, even if he doesn't want it. Because the alpha wants, and Sam's hardly able to fight that.

"Pull out. It's too big. I can't handle it."

He doesn't expect Bucky to listen. Will try, though.
