Shiori Natsumi, the petite Japanese teen, eagerly explores her new vibrator in the privacy of her room. Her slim body writhes as she presses the pulsating toy against her wet pussy, fingers dancing on her clit. She's close to orgasm when her mother walks in, catching her mid-squirt. Embarrassed, Shiori is ordered to clean up, but her mother has other plans. She binds Shiori's wrists with a silk scarf, turning her daughter's solo play into a BDSM lesson.
