A female badminton club student experiences anal play for the first time. Approaching it casually, as if taking on a part-time job, she lies down on the bed and opens up her own anus for display. The sight of an anal pearl slowly entering her pretty back door feels strange at first, but gradually the entire length disappears inside, swallowed completely to the base. Though clearly hesitant at first due to it being her debut, she begins moving her hips to create a piston motion. With two fingers inserted deep into her anus, stimulating her inner walls, she is overwhelmed by pleasure—despite this being her first anal experience—and eventually loses consciousness.
