Hinano, a female student. Recently, she got a boyfriend and was a quiet honor student having a pure relationship, but she has a tendency to fantasize and indulges in masturbation while imagining having sex with older men every day. She liked her boyfriend Yuugo, but she just couldn't direct her sexual feelings towards him... One day, she was attacked in her sleep by a man named Koji from the neighborhood who brought the circular, and they had sex. As a result of that, she falls into days of lewdness, involving Koji's drinking buddies as well.
