Ayumi, a bubbly Japanese yoga instructor, finds herself in a compromising position when a stretching session with her student, M-kun, turns into an intense cowgirl ride. Her flexible body, still warm from yoga, responds eagerly to M-kun's touch. She straddles him, her perky breasts bouncing as she grinds her hips, taking his thick cock deep inside her. The couple, caught up in the moment, forgets about the camera, capturing their every thrust and moan.
