After ten years of marriage, Yuka is treated like part of the furniture by her husband and has gone years without sex. Desperate for relief, she tries a supplement from a beauty website. Its supposed detox effect makes sweat pour from her body and sends her to the bathroom constantly, while her pussy begins producing excessive fluid. Soaked and hypersensitive, she can no longer control her body's reactions, and the supplement-driven arousal disrupts her life as it pushes her toward uncontrollable wetting and repeated orgasms.
