Komachi Ito's lessons are thrilling experiments that will undoubtedly shock her students. Using her own body as teaching material, she refrains from making the first move, instead wearing an open-chested outfit and striking provocative poses to entice the students into touching her. Meanwhile, Rei Odagiri senses the students' desires and takes the initiative, actively approaching them. As class begins, the students grow nervous, gradually feeling arousal in their groins until they become fully excited. Noticing this, Rei slowly draws closer, gently caressing their exaggerated, erect areas. The students' eyes glaze over with lust, their pants come off, and faced with their throbbing cocks, all rationality vanishes—launching straight into hands-on health and physical education practice.
