A new standout title arrives on DORA MAX Extreme! It begins with a simple question: "Hey... which one do you like more, Takachan?" A heart-pounding love story unfolds between twin sisters, Mami and Yumi, childhood friends of the protagonist, who's secretly been in love with both. The story takes a sharp turn when the protagonist ends up alone with Yumi. Though the sisters look identical, their personalities and sexual styles are complete opposites—creating explosive chemistry. Yumi is a mischievous, aggressive seductress skilled in bed, while Mami offers deeply emotional, devoted lovemaking. The bond and tension born from their differences, along with the intense love triangle under one roof, lead to an unforgettable climax.
