In co-ed health and physical education class, students learn about the differences between male and female bodies. Today's lesson focuses specifically on the male genitalia. There are various types of erections, and understanding their unique characteristics is essential. The class will also study in detail the mechanism of ejaculation. Serving as a model is the serious yet sexy new teacher, Reona Tomiyasu. While respecting her role as school physician, she gently engages with the students' bodies.
"Should I hold it firmly? Or is it better to do it the way I normally would?" Reona Tomiyasu kindly asks, demonstrating how to touch and stroke for the female students. Gradually, their tension begins to ease. Next, class president Noa Yuika takes her turn, taking the teacher's penis into her mouth. The teacher carefully instructs, "Hold the penis firmly! Take it deep into your throat!" Going beyond her duties as a school doctor, she gently cradles the class president's groin.
"Now, let's try tracing the vulva with your fingers… or perhaps inserting them into the vagina," Reona Tomiyasu continues, teaching about masturbation. Her dedication to imparting both accurate knowledge and firsthand experience leaves a strong impression. Through this lesson, students gain important insights into the significance of self-pleasure and the correct techniques.
While maintaining her professional role, Reona Tomiyasu gently touches her students' bodies, and her warmth becomes a key factor in deepening the lesson. The class president shyly asks, "U-um, is it really okay for me to be doing this in front of everyone…?" yet gradually grows more accustomed to the situation.
"Deeper than before… it's going deeper now…" Noa Yuika reaches orgasm using the rolling motion—this moment of ecstasy defines climax. The cowgirl position is introduced as a proper sexual posture, with guidance on pinching nipples, supporting the hips, and other techniques. Encouraged by cheers from the male students, the class president is praised for her performance.
By blending education with experience, this class becomes a pivotal moment of growth for the students. Thanks to the class president's outstanding participation, the lesson reaches new heights. Applause fills the room, expressing gratitude and admiration.
