"I'll fuck you so hard that it's all you want," Bucky says, trying to ramp her up even more. He has a whole list of things he wants to do to Natalia and if she's going to challenge him, he's going to rise up to the challenge. Maybe she has qualms about biting him but he has none about biting her and he sinks his teeth in her right at the back of her neck; that's how werewolves do it, after all, and he's more wolf than man half the time.

It normally makes a woman go limp but for a split second, Bucky's not sure what the fuck it's going to do to a vampire. Probably nothing but fun, he thinks and he keeps fucking her hard. Hard and fast and without a lot of emotions: that's what's safe. If he does it this way, there's no feelings and no relationship to worry about. Just an itch to be scratched.
