Kirin is supposed to be meeting Noriko, but decides to skip out on her to have sex with Sensei instead. She doesn't expect to enjoy her first time, but thinks that it's something she has to get out of the way to enjoy it in future — she likens it to a doctor's appointment which will "fix" her body to be the way it ought to be. Before she can get her wish, however, Noriko comes looking for Kirin. They have an argument over whether Kirin is doing anything wrong, and eventually agree that Sensei should leave.
