In this adult school role-play, the swim-club members file a very unusual complaint: their voluptuous H-cup coach, Ms. Riri, wears a revealing, nearly transparent racing swimsuit, spreads herself to tease them, and leaves everyone too hard to practice. Her “instruction” includes ordering any visibly aroused adult student to have sex with her, all while she delights in satisfying her own enormous libido. The team wonders whether they can keep this sex-crazed teacher all to themselves.
