A female teacher, Sayuki, has fallen to being a pet at the beck and call of a certain student. Another merciless day of torture training begins today. Bullying her large breasts before class, forced fellatio. Secretly tormented with a vibrator during exams, stifling her moans, forcibly vibrated and raped by a colleague teacher, and further humiliated with fierce fucking by a jealous student, reaching orgasm multiple times.
