I'm a swimming instructor at a swim school, having an affair with a married student of mine. She wears a tight-fitting swimsuit and boldly masturbates in front of me, spreading her legs wide to expose her groin, climaxing in an intensely erotic manner—the peak of sexual allure. Aroused by a man other than her husband, she grows increasingly daring. Featuring binaural recording for a realistic, immersive experience, this film delivers even greater presence when viewed while seated on the floor.
