It's not that going slower feels better as such. It's just that, if Aoba went any faster, he's not sure he could last for very long - and his priority here is getting Luxaela off, not himself. But that is not only embarrassing, but also a lot to talk about in a purely technical sense, and he really needs to focus on other things right now.

... Then again... kissing might be the good kind of distraction.

"They don't scare me." Well, not in a bad way, at least. But they really don't bother him much at all - not at this point - even if they maybe should.

Thrusting back in, he holds where he is for a moment, and leans in, staring at Luxaela's mouth. He really does feel like kissing, and so that is what he does, though he starts it innocently. It's good enough for him, for the moment: even a barely-there touch of lips electrifies all his nerves.
