Rika Miama - Stepfather's sex slave: beautiful student goes mad for sex after years of training

Rika is a student. There is one place she goes to every week. It's the house of a guy she met on a social networking site who lives in the next town over, and there are two of them, including the guy he lives with. In that dirty room, a certain act is taking place... The man's burly hands ravage the girl's soft, white skin. She becomes more and more addicted to the stimulation that she cannot experience at college.
