Shameful! New female teacher used as a lewd sex education subject (SVSHA-036)

A beautiful new female teacher was assigned to teach at a boys' school. The students used her alluring body as teaching material, behaving extremely seriously in health classes. Full, round breasts, a slender, supple waist, and a vagina the boys had never seen before. This was a new era of sex education using live teaching materials. "Teacher! If you keep being so shy, we can't learn!" To ensure the students learned thoroughly, the teacher was required to bury her enormous buttocks against the wall, practicing "wall-butt learning." Faced with those full, protruding, peach-colored buttocks, the boys couldn't help but gasp. When her breath touched her anus, it involuntarily twitched. When thick, sticky vaginal fluid secreted and dripped, the lesson moved into "male penetration experience." The teacher's buttocks trembled violently during a peak orgasm. "Unprotected intercourse is the foundation of sex! Everyone must remember this before going home!"
