Chimimouryou – Episode 1 (PV (Preview))

In this premiere episode of the adult OVA Chimi Mouryou (痴魅悶凌 前編), former track star Shiho Amatsuka, once a top athlete alongside her close friend and rival Leila Kuranaga, suffers a devastating injury that forces her to retire from competition and become the team's manager. As the third-year students navigate their final high school days, a new advisor, Inose, arrives and drastically alters the club's dynamic—earning a terrible reputation among the female members.

Shiho frequently receives private summons from Inose. The crisis escalates when he confronts Leila with irrefutable evidence of "improper heterosexual relations." To protect her friend's future and dreams, Shiho steps in to negotiate. Inose agrees to drop the punishment in exchange for three strict conditions: every morning, Shiho must attach a clitoral suction device before school and send proof photos; she must prioritize all his commands without resistance or removal during the period; and no intercourse or kissing is allowed—any violation by him carries severe consequences.

Shiho pretends compliance to gather evidence for revenge after the last tournament, planning to expose him. However, the relentless daily torment and escalating demands begin to erode her resolve, awakening hidden masochistic desires in this intense hentai blackmail and training story.
