ZOZO-023 — Coeducational School Health And Physical Education 2020, 4Th Period: About The Structure Of The Male Genitalia

"There are two types of erection: central and reflex-induced." "Let's remember oral sex! There's no harm in it!" A health and physical education class is held at a coeducational school to teach correct sexual knowledge. The theme of the fourth period is "About the mechanism of the male genitalia," and the female students stare at the penis of a male student lying on his back. "The veins are visible on your penis... is that improving the b** flow...?" a female student licks the head of the penis as instructed. "Yes. Please lick it gently. If you don't learn this properly here, you will lose out." "Something is coming out from the tip of the head of the penis..." "It's pre-ejaculate. It's okay. By sucking it like that, you should feel affection. You will gradually get used to it. It's a technique. Now, I'll teach you how to masturbate, so show me your pussy." Another female student starts masturbating in front of the male student who is receiving a blowjob, and he can't help but ejaculate (lol). "Shall we try stimulating your vagina next? You'll understand the penis better that way, right?" he says, as he plunges his young big dick into the female student! "Do you know how it feels different in missionary and doggy style? It changes a lot depending on the angle and the position of the uterus." The female student swings her hips in cowgirl position. "It looks like you're getting the hang of it. When your husband is tired, please use cowgirl position." Even in this short time, it seems she has learned a lot about penises (lol). Congratulations on graduating from virginity!
