ZOZO-020 - Co-educational health and physical education 2020, 1st period About physical differences between men and women during the second growth period

Completely naked! Shame! Health and physical education at a co-educational school where men and women learn about the differences in their bodies! ``It's big... it's hard, and it's kind of hot...'' said the female student, blushing and touching her penis. And this cutie. Class president! The importance of sex education is being emphasized these days! Since we are still in the process of growing up, we have to learn the correct knowledge of sex! The theme of the first period was "physical differences between men and women during the secondary sex characteristics". I'm at an age where I'm really curious about the body of the opposite sex. First, let's touch the boy's body and feel the difference. ``Come on, take it off. Now let's show the virgin boy your breasts and pussy!'' ``What? I don't like it...'' ``You're the representative of everyone, you're the chairman. If you don't take your clothes off, everyone's grades will drop because of you!'' Feeling responsible, the female student on the committee begins to take off her clothes. a! Cute nipples and pussy exposed! Exposed to the curious gaze of male students, this is a shame! Shame! They sit face-to-face with men and discuss the differences in the thickness of their body hair, the differences in the color of their breasts and nipples, and so on. This is a serious class, but it's extremely embarrassing! ``Teacher, the chairman's nipples are getting erect!'' As we gently touch each other's genitals, the tip of the glans gets wet... and the handjob from the chairman is amazing... it's so hot! Ahhh, even though I was in class, the chairperson made me cum (lol).
