Walnut is an 18-year-old high school girl with hidden huge breasts who applied for a high-paying erotic part-time job. Walnut has a cute and refreshing smile, but she starts off by confessing that she masturbates three times a week and in the shower during erotic talk. We mix an aphrodisiac into her drink, and use the opportunity to start the erotic part-time job to rub the liquid aphrodisiac directly into her pussy. We then ask her to recreate the way she normally masturbates, and the aphrodisiac effect makes her cum hard, making a raw, squelching sound! Walnut, who has become extremely sensitive, readily accepts our requests and cums hard with uniform sex and toys. Furthermore, during aphrodisiac oil sex, she sweats, her face is flushed, and she cums repeatedly while trembling! When we thrust into her hard with a raw dick, she drools and cums hard, and at the end, she ascends to heaven, screaming, "Mom!"
