Slender, healing-type beauty Seta Mai appears as a female teacher, guiding students through an erotic lesson in a "sex education" setting. With a refreshing smile, she greets them: "Today, let's learn about the spots that feel good for men!" Prompted by her words, she demonstrates sultry tongue techniques by passionately licking a realistic cock-shaped dildo.
As the erotic instruction continues, two male students experience rimming for the first time. Matching their excitement, Mai praises the color and shape of their cocks while showcasing various techniques—double handjob, handjob ball-licking blowjob, double teasing reverse handjob, and anal licking. The intense stimulation causes one of the cocks to erupt prematurely.
Still craving more, Seta Mai invites the remaining male student to the infirmary, where she performs anal licking on him using a portable bed. The teacher's own anus is also flipped open and licked, leading into a 69 position scene. Moaning softly yet enthusiastically, she gets her creampie thoroughly drained by the eager students, ultimately reaching a blissful, transcendent orgasm.
