Yusei came up to Tokyo to his uncle’s house for cram-school summer classes. Every night at the uncle’s house the uncle and aunt have sex so loud he cannot study. Frustrated, one day Yusei forcibly fucks Ayaka, but the uncle finds them, beats him badly and throws him out of the house. For revenge Yusei brings a delinquent senior and, in front of the uncle’s eyes, makes Ayaka cum over and over and does consecutive creampie seeding fucks.
