Reika Iijima is a piano teacher who can't help but indulge in masturbation whenever she's left alone. In her student's room, with no one around, her hands inevitably wander between her legs. Facing the camera, she unleashes a stream of vulgar, erotic words while striking bold, seductive poses—her expression tinged with a hint of shyness. She strokes her wet pussy with her fingers, then thrusts a vibrator deep inside, producing squelching, lewd sounds. Her shamelessly lustful display holds an irresistible allure, captivating anyone who watches.
