Based on the erotic game by Blue Gale Light. Yui and Shiori are cousins who work part time at the Clover Supermarket. One night when they return home, they just remembered something they forgot and Shiori returns to the Supermarket to pick up the items. However, at that time, Shiori is framed and forced to do something perverted or she would be reported to the police. (Source: Translated from Nekopoi)
