DVAJ-136 Reunited with my cousin who taught me how to masturbate a long time ago after 5 years Nanami Kawakami

When I met my cousin for the first time in a long time, she was all grown up... Five years ago, Nanami, a student at school, started having a relationship with her cousin Teppei. However, they didn't have sex, they just taught Teppei, who didn't know women yet, how to masturbate. Both of them were acting strange at that time. Since then, things have gotten awkward and Nanami has been far away from him.
