One day while I was studying in the library, I became the target of two female students who were famous for being sluts. Misono, who gets all her nutrition from her breasts, and Rin, who is a bitch even though she looks neat, end up competing for my dick, and it's my first 3PSEX in my life! After getting a taste of library sex, the girls keep coming to me and wondering which way I can insert them.
