When his father is transferred to another location, Rika comes to help him and become his tutor! While studying, Shota is interested in Rika's breasts and keeps playing with them, but Rika says, "If it's for my education..." and holds back and gets turned on. Shota gets carried away and does whatever he wants with Rika, from massaging her clothes while she's doing the laundry to giving her a titjob and blowjob, and even begging for sex in the bedroom because he can't fall asleep!
