MC is a male hit by a truck and reincarnated as a girl. He is bullied by his sisters and misses being a boy to have power over girls. One day MC is browsing a black market website and finds a magic ring that turns a clitoris in to a cock and thinks having a cock will give him power over girls (and his sisters). He buys it. When it arrives before MC could open the package it is taken from him by his sisters. They open it and steal the magic rings (an extra one was sent, because plot). MC tries to steal it back and sneaks into his oldest sisters room and it turns out she set a trap (page 8). Story ensues. Page 55 MC discovers one of the magic rings on the table and gleefully takes it. After that the story splits into 4 branching paths and endings based on who walks in on him during his solo session: Page 60 older sister. Page 69 middle sister. Page 79 both sisters. Page 102+ all the cock rings are cursed (sisters buy an extra one for MC).
