"C'mon, Natalia," Bucky murmurs against her thigh before moving his lips back to her clit to work it some more. He knows she has to be close, the way she's squirming, but she's holding back for some reason and he just wants her to fall apart under him. It feels as good for him as it does when she's getting him off and he craves it.

He doesn't change what he's doing but keeps it steady, not wanting to let up when she's so close and potentially ruin it. There's nothing he would want less than to ruin it for Natalia.
