Taku Yoshimura, the lecherous coach, sneaks into the locker room after hours to find Kanno Hina, the petite gymnast, still in her leotard, stretching. Hina's small, perky tits and perfect ass are on full display, driving Taku wild. He approaches her, his hard-on visible through his shorts. Hina, initially shocked, feels her pussy moisten at the sight. She's never done this before, but Taku's experienced hands and dirty talk soon have her eager to learn. In the bathtub, Hina tentatively licks Taku's cock, her petite body trembling with anticipation.
