Ayu, who loves vinegar, enjoys replacing her bathwater with vinegar every time she bathes. The thick scent of vinegar fills the bathroom air, and her erotic figure becomes increasingly aroused as she masturbates, excited by the unique tangy aroma. Stimulated by the sharp fragrance, her excitement builds higher and higher. She chases pleasure while reveling in the sour scent, becoming completely absorbed until reaching multiple orgasms. Even afterward, as she showers herself with vinegar, her satisfied expression—almost as if indulging herself—perfectly embodies her distinctive, fetishistic play style.
