Tsukasa-sensei's after-school special lessons lead students into an erotic, heart-pounding experience. Wearing a tiny bikini beneath her suit, the teacher teases with seductive poses, driving her students wild with desire. For students caught hiding adult magazines, she delivers punishment by stepping on them with her high heels, while openly showing her underwear and demonstrating masturbation as part of her explicit sex education. When a student can no longer restrain himself and lunges at her, he is tied to a chair and subjected to intense vibrator stimulation, handjobs, and even forced vibrator penetration. This bold and erotic classroom turns into a series of thrilling events that deeply excite and unsettle the students.
