A high school student named 'Hana' came to Tokyo for an exam and stayed with her relative, the Nakano family. The Nakano family has a son named 'Tadashi,' a delinquent who spends his days in front of the PC jerking off instead of studying. Hana and Tadashi reunited after several years... and to their surprise, Hana's breasts had evolved into enormous tits! Taking advantage of their past intimacy, such as bathing together and sleeping in the same bed, Tadashi reaches for Hana's breasts.
