Kenta's older sister, Yui, got married and left home five years ago, but after her divorce she returns home. Kenta is meeting her for the first time in a long time, but after several years she has become a grown woman and his crotch is shot straight through...She has rocket-like breasts that he hadn't noticed before, a waist that is rarely seen even in the city, and a round, firm butt that is firm underneath... Kenta is unable to calm his excitement and begs Yui to teach him about sex. #HanchoP
