Rinkan Gakuen

The students at fancy Rinkan Gakuen are fascinated with new science teacher Ms. Haruka Taifuuji when she's hired in the middle of the year. As the hot, busty MILF faces their questions, her teen stepdaughter, Ai, gets some very special instruction from another teacher, Aihara-sensei. Ai gets a lesson in giving blowjobs, then watches as Aihara-sensei is fucked by her fellow students... but she doesn't know that outside, her stepmom is turning into a super slut who demands all the cock she can take in her mouth, pussy and ass!
