That may or may not have made this player shriek like a little girl.

Thankfully, Kaworu is not prone to that sort of thing. It doesn't matter, to him, whether or not he has been kissed before. Somehow the experience makes him feel novice all over again, which is... not an unwelcome feeling.

Maybe this is an effect of the painkiller (and if so, Kaworu can convince him it was a hallucination) or maybe Miharu actually meant it. He doesn't know yet. All he knows is what he does, and in that, Kaworu can only concentrate on the act. He kisses Miharu himself, when the first kiss is over, just to make sure he stays there.
