"I don't!" It comes out a little defensive, but he can't help it; he really doesn't want to just do nothing. He feels kind of bad for how little he's doing as it is - and if that's not entirely reasonable, well, that's how he feels all the same.

So, he knows what to do now, and he's definitely willing. It's just kind of weird when he's not exactly an expert... and then there's alien anatomy... but then, maybe that actually makes it easier..? (Why is he wasting time thinking about this stuff in the first place?!)

With Luxaela sitting, at least the height difference is mostly taken care of. Aoba strokes himself a little, making sure he's fully hard, as he positions himself closer to Luxaela's opening. The size of the man (er, alien) still makes this kind of weird, but... definitely not in a bad way. And it definitely looks wet enough in there... Pressing up against Luxaela's opening isn't so bad; the rest should be fine, then? It's just, somehow this feels like such a big deal, and like no big deal at the same time.

"Here I come..." Yeah, that's definitely a sexy thing to say, in the way that it isn't. But he couldn't bring himself to not at least say something.

With that, he adds a little pressure, trying not to force anything too fast.
