ZOZO-222 - A high-quality class where male and female students learn about the differences in their bodies by being completely nude, 3rd period of health and physical education at a co-educational school, focusing on the mechanism of pregnancy.

Can learning about sex with classmates' bodies solve the declining birthrate? A special class started with a national idea. The theme of the 3rd period is 'Mechanism of Pregnancy'. This time's textbook is Hinami Meguro. 'Huh? Are you saying you're going to put a camera in there...? What is that!' Even she, who is always assertive, has no chance against the nation. A CCD camera is inserted while she is on all fours, and a vaginal stream is broadcast to the whole class. She can't stand the fingers and tongues of the boys exploring her vagina, and she explodes while yelling 'Don't look!' With her body completely prepared, the school doctor inserts a large penis. Meguro became a sacrifice for everyone to learn the correct pregnancy techniques. She repeats convulsions while a large amount of semen is poured onto her!
