He doesn't even really care that whatever she just said wasn't in English. Half the shit people say during sex doesn't make sense, in or without the language, and he's pretty good at picking out the underlying emotion in them and responding to that instead. That is, when he can respond. Again, he's a little limited right now, but being open like this for someone, doing what he can from this position, that's more than good. He's making noises of his own, a grunt every time she slams home, deeper and deeper it feels like even though he knows that's impossible. Groan when she pulls away, even if it is just to come right back.
