The narrator tells us that he's been staying with Mizuki for a week now. He's not sure if he'll be able to come back tomorrow, but he does want to meet up with him. He tells her that he hasn't had much to talk about lately, so he doesn't have much to say to Mizuki. The narrator says that she's "horny" , which is a fancy way of saying that she has a lot of fidgety muscles. Mizuki's fingers are a lot longer than hers, and the two of them are constantly rubbing each other's ass, which makes the narrator feel "good" for the first time in a long time. She tells Mizuki that she wants to put her fingers in her pants, but Mizuki won't let her do it. He says that they're going to start working in groups
