A secret lesson conducted in a classroom with just the two of them. The female teacher 'Nanako-sensei' leaves a student alone in the classroom under the pretense of extra tutoring. Intimate kisses and lewdly stimulating the student's erect penis with her feet and knees. She exposes the student's shirt, licking his nipples with a sticky tongue. She performs foot jobs with her stockinged feet, deep throat fellatio resulting in oral ejaculation, facial riding, and more to manipulate the student's body. Her vagina is drenched with love juices. She mounts him in a reverse cowgirl position, inserting his hard penis. Afterwards, she continues with rear entry, standing doggy style, missionary, and elevated missionary positions, sexually exploiting the student's semen with her raw vagina. When she pulls out her fingers from her vagina, the semen deposited inside drips down. An illicit tutoring session conducted in a secret room where no one can know.
