Sinopse

Shinya is on his way to a school incinerator with dust boxes. He passes three students. They stare at him and giggle at him. He doesn't know why. When he looks into the incinerator, he finds a girl's underwear inside.... One the next day, he finds a love letter without a name. He goes to the place written on the love letter after school and finds Sayaka masturbating herself. He meets the eye with her and he runs away. The next day, Sayaka asks him not to tell anybody about what he saw yesterday. She says she does anything he wants and starts giving him a blowjob. Shinya doesn't know what's going on, but the cooler he gets, the more his sexual desire arouses, "She can be my sex slave...."
