Naked!Shame!A co-educational school where men and women learn about body differences! "It's big, it's hard, it's kind of hot...", a girl blushing and rubbing her penis.And this cutie.Class president!These days, the importance of sex education is called out!I'm still in the process of growing ●Because I'm a school student, I have to learn the correct knowledge of sex! The theme of the first period is "Body differences between men and women during the second sexual period."Around the age when the body of the opposite sex is very worrisome.First of all, from where you can feel the difference by touching the boy's body. "Come on, take it off. Now let's show the virgin boy your breasts and pussy!" That's it!" The chairperson's female student feels responsible and begins to take off.a!Cute nipples and pussy are exposed!Being exposed to the curiosity of a male student, this is a shame!Shame!Face the boys and talk about the difference in the thickness of their body hair, discuss the difference in the color of their breasts and nipples...This is a serious class, but it's so embarrassing! "Teacher, the chairman's nipples are getting erect!" While gently touching each other's genitals, the tip of the glans is getting wet... The chairman's hand job is amazing... Dopyu!Ahh, even though it was class, the chairman made me go (laughs).
