Kaho, a new female teacher at an all-boys school, is made into a learning material for sex education. Rebellion is not allowed, she can only endure even if she's embarrassed. She takes off her clothes in front of the male students, becomes completely naked, and exposes her genitals. Is she excited from being watched, or is it her love juice gushing out! She can't refuse even the practical exercise of sexual intercourse because she's told it's for becoming a proper teacher. She reacts sensitively to the intense insertion piston she experiences for the first time and cums like crazy. The students are also very excited by the massive semen creampie finish.
