A growl escapes Bucky's lips at that, deeper, closer to a warning but without any actual challenge in it. "I'm going to mark you," he warms, promises. He's too far gone to want to turn it down, not now. Not when his body is telling him yes, this one, please and his mind is agreeing with it. Steve's gotten himself an aggressive omega for a mate, it's only fair to warn him that by the time they sleep through until the next night, Steve will have more marks on him than just the mating bite.

He rolls his hips, grinding against Steve, tugging at the alpha's ceremonial clothes, confident his alpha can do the same with Bucky's. "Claim me," he moans, letting the heat take over. He's ready for this, purring lowly, encouraging Steve to take what he wants.

"Breed me, oh god."
