"How can I do something... so perverted... when I have a boyfriend...?" Miyuki suddenly returned to her parents' house after she quarreled with her boyfriend. But the one who welcomes her home is an international exchange student, Louis. Although she is initially confused by his apparent lack of sense of personal space, the two take to each other during dinner.

She tries to push him away, but she can't control her body well because of the alcohol...! "You fell asleep right in front of me so easily... You're way too defenseless." He caresses her sensitive spots with his big fingers, making her body heat up... she's about to be ravished by that impressive member of his...!!
