"I hate sex," the narrator tells us, "on our first day of living together" . He's convinced that his childhood friend, Viola, made him fall in love with Viola's sister, Riko, and that's why he hates sex with her. But he's also convinced that Viola will never change her feelings for him, even if she does change her mind about him. The narrator asks Viola if she's ever kissed a girl, and she admits that she hasn't. Viola tries to get her to touch the girl's breasts, but Viola doesn't want to do it, because she thinks it's too painful. Viola says she'll try to squeeze the girl, but she can't, because the girl is so soft. Viola finally manages to squeeze Riko's nipples, and they're so close that she can barely hold them back. She's so close, in fact, that she slaps herself for not being able to keep them in place.
