AIKA is close to marrying her fiancé when her worthless ex suddenly appears at her home. Though she remembers how toxic he was, she also remembers their incredible sexual chemistry. He penetrates her and urinates inside her instead of creampieing her; after initial shock, the unfamiliar sensation makes her climax repeatedly. Soon she becomes completely submissive to the pleasure and begs him to fill her with urine herself. With her body thoroughly trained, she drinks urine and squirts back until semen and piss mingle inside her and ordinary creampies no longer satisfy her.
