Assuming it's a present from her husband, she happily puts it on, but the very next moment, her husband's stepson Shinya suddenly enters the room and sees her in that state, revealing that the lingerie belongs to him. Despite trying to resist his forceful advances, she finds herself reminded of long-forgotten pleasures as a woman by his penis, which stands erect far more impressively than her husband's. From that day forward, a twisted triangular relationship is formed, and a new, taboo sex life begins...
