GNS-156 — [Sexual Desire Regulations] Masturbation on school grounds after school is strictly prohibited. Violators will be filmed as evidence and punished with unprotected intercourse resulting in pregnancy.

In the deserted gym storage room after school, a girl secretly fondles her crotch, hiding from her classmates, when she is suddenly tapped on the shoulder from behind, causing her to panic. "What were you doing? Huh?" the gym teacher, dressed in a tracksuit, asks, and before she even has time to put her panties back on, she is pushed down and f** to masturbate—a tragedy for 16 girls! Although they initially resist, in the end they even beg for him to cum inside them!
