During the sex training camp at the university, the girls are forced to perform cum-troops. One of the girls is so excited that she can't stop rubbing her lips. She wants to see if Touma will say the same thing, but she's afraid that he'll say it too. She's also afraid that they'll disband the sex club after all, since Touma hasn't been seen since he got his job. The girl is sorry for all the trouble that's come her way, and she apologizes to all of them. She says that it was her fault, too, and that she'd like to be friends again. She tells them to be ready for the night, since she'll be getting ready for sex with five other guys that night. She also tells them that she wants to say her name to them, but that she doesn't want to get carried away with the idea of saying her sister's name, since it would make her look like a sissy. The girls are shocked that she would want to say such a thing, and the girl says that she likes her too, too. The train has just begun, and it's time for sex.
