May, a new female teacher who loves swimming and became the advisor for the swim club. Delinquents targeted her for her weak appearance and personality, tricked into teaching them how to swim, and then raped in the pool after school. The nightmare didn't end there; more students joined in, and the female teacher's vagina in her swimsuit was continually violated. She had never done it inside with any of them before, but the students' brutal cocks were inserted one after another, filling her vagina with thick semen.
