ZOZO-023 Health and physical education of co-school 2020, 4th period About the mechanism of male genitalia

“There are two types of erections: central erections and reflexive erections.” “Let’s remember oral sex! There is no loss!” Health and physical education class. The theme of the 4th period is “About the mechanism of male genitalia”, and the girls who stare at the boys’ dicks lying on their backs. A girl student who licks the glans as instructed, “Is the blood vessels protruding properly …, is the blood flow improving?” “Yes. Please lick it gently. If you don’t learn properly here, you’ll lose.” “Somehow, the juice came out from the tip of the glans …” “It’s Cowper’s liquid. It’s okay. You should feel affectionate by giving it that way. You will get used to it. This is a technique. Now, I will teach you how to masturbate, so show me your pussy. When another girl student starts masturbating in front of the boy student who is being blown, she ejaculates irresistibly (laughs). “Let’s stimulate the vagina this time? You can understand that better, right?”, Inserting a young big cock into a girl student! “Do you understand that the sensation is different between the missionary position and the back position? It changes a lot depending on the angle and the position of the uterus.” A girl student swinging her hips in the woman on top posture. “It looks like you’ve got the hang of it. If your husband is tired, please put him in a woman on top posture.” Even during this short period of time, he seemed to know a lot about his dick (laughs). Congratulations on your virgin graduation!
