The female body is at its most erotic when it's in motion. Rei Kamiki, a former track and field athlete with a superb body, challenges herself completely naked in an all-outdoor sports test. Her athletically trained physique and beautiful breasts are on full display in the sunlight as she performs a beautiful back flip... A shuttle run has been added to this episode. The intense thrusting immediately afterwards brings her body to the limits of pleasure like never before.
