During the university sex training camp, the girls tease each other about their butts and butts. One of the girls, Serina, tries to get the other girl to show her the dance she taught her, but Serina is too scared to do so. She tells Serina that she's going to rub the girl's clit with a wet cloth if she doesn't want to have sex with her. Serina tells her to stop teasing her and to put the wet cloth in her butt. She's so scared of what she'll do if she does have sex that she starts to cry.
