Mari, a fan of underground idol Haruna, placed a on the crotch of Haruna's poster and enjoyed fantasy SEX with her today. One day, Mari, who broke into Haruna's dressing room, witnessed the act of indecent milk rubbing between Manager Kuroki and Haruna. It was MARI who tried to stop it, but instead, it was stabbed in the back of the vagina with a strap. Kuroki senses that Mari is overwhelmed and debuts as an idol, but... Intense compression and excessive physical intercourse. Haruna's string play!
