Five days after her parents' remarriage, high school student Mei found herself living under the same roof as her new stepbrother, whom she had always been looked at with disgustful eyes by. Unfortunately, her secret relationship with one of her teachers was exposed... Feeling cornered, Mei put on a strong front but little did she know that she had been drugged and subjected to relentless teasing play which eventually made her body tremble and respond, leading to an orgasm against her will. From then on, Mei indulged in the pleasures of taboo incest, becoming increasingly addicted to the sexual encounters with her hated stepbrother despite her heart telling her otherwise.
