In this adult teacher-and-student role-play, the beautiful, stylish Arina-sensei reveals the secret side she shows only to her favorite student. After class, she calls him aside, takes him to a hotel, strips and restrains him, then changes into obscene bondage gear and declares him her ejaculation pet. She keeps teasing his cock until he shoots and squirts over and over, even after he begs that he has already come. The relentless session lasts until sunrise, wringing 20 loads from him in an all-night orgasm marathon.
