START-248 | Riko Hoshino's first naked sexual assault sports test

The female body is at its most erotic when it's in motion. Riko Hoshino, who has outstanding proportions, challenges herself to an all-outdoor sports test completely naked. Her muscles contract repeatedly, and her whole body is covered in sweat. She uses all her physical strength to the fullest and takes on the challenge in earnest. Measurements are taken when she wears a vibrator and when a penis is inserted. She shows an expression of near-fainting, caught between fatigue and pleasure.
