イヂって！若妻てぃ～ちゃ～♪ ～美人女教師の性教育的指導～

One afternoon, Shinya Kamijo turns up at his former high school. He hasn't set foot on campus in a long time—as a child prodigy, he sailed through his studies and skipped his final year to go to college in the States, where he managed to graduate in just a year. He is handsome, impeccably behaved, excellent at sports, and so academically gifted that his ordinary teachers simply can't keep up... and if that weren't enough, his father is the school chairman. Deep down, however, Shinya is a bonafide fckboy obsessed with women's bodies. Normally, he feigns innocence and acts like the perfect pupil, but his mind is filled with thoughts of sex. After completing the enrollment procedures for his return to school, Shinya meets his new homeroom teacher, Ruri Saeki, in the teacher's office. Ruri's vivacious curves and coolly gentle personality soon have Shinya's blood racing. "This teacher... I am so gonna fck her!" Making sure not to blow his cover, Shinya keeps up the star student act at first, but is soon playing naughty tricks on her left, right, and center. To his surprise, Ruri doesn't seem fazed at all, reacting calmly and politely(?) at every turn. Her response only increases his determination to have his way with her, and when the other female teachers and his classmates begin to get involved in his antics, the school becomes a den of debauchery.
