This time, Mari-chan, an active member of the track and field team at a certain famous university, applied to appear in an AV. She doesn't have time to find a boyfriend, but right after the tournament she's so excited she can't stop being horny... She showed up to the shoot right after the tournament and was an incredible slut! She uses her well-trained, slender, abs-muscle body to pound you with piston-like movements in cowgirl position until she's satisfied! Once the switch is flipped, she changes gears and begins a high-speed grinding cowgirl position with her hips swaying in an erotic way! Female athletes are just so erotic!
