痴魅悶凌 前編[せぶんがー]
Shiho Amatsuka and Reira Kuronaga are inseparable track club members chasing the same dream. After a serious leg injury forces Shiho to retire and become the team manager, a new advisor named Inose (with a terrible reputation) enters their lives. He blackmails them with compromising evidence of Reira, forcing Shiho to agree to humiliating conditions — including wearing a remote clitoral vibrator to school daily and sending proof photos — to protect her friend. The episode dives into intense submission, teasing, and sexual coercion as Shiho tries to endure while planning to gather evidence against him.
