"No. But. You're bruising." Which is apparently Zemo's fault now and not any indication that Bucky should stop treating him like a chewtoy.

And, normally Zemo gives very clear instructions. Like 'fuck the movie, suck me off' would be a much better directive than what Bucky can't decipher whether it is a good kind of writhing or an uncomfortable kind of writhing.

Bucky lowers his head again, hopelessly confused but Zemo said stopping hasn't crossed his mind, so he's just going to keep going. He grazes his teeth so dangerously close, canines threatening to bite through a very vulnerably located clit at the moment, but the teeth give way to nipping lips and an eager tongue when Zemo grips too hard into his hair.

Apologetic kisses are littered liberally over the bruises on the inner thighs for as long as Zemo lets him stray away until he feels that hand yank him back in again. His scalp is starting to tingle now but he could eat Zemo out until the credits have finished rolling - if he can handle being teased and stimulated for that long - and neither of them would be tired.

Maybe they can't. You know. Do that. But their current... Predicament? Wouldn't preclude them from doing. You know. Butt stuff.
