Mitsuki Nagisa and Hono Wakamiya act as double masochistic women in erotic costumes. Every time the M man cries out "No more!", they laugh and intensify their teasing, appearing to have too much fun, showcasing their natural and uninhibited behavior. They engage in intense sexual play, including squirting, endless ejaculations, and near-climax teasing, one after another. These two are wickedly cruel as they take the M man on a tour of four "hells of pleasure": a hell of endurance, a hell of urethral play, a hell of handjob near-climax teasing, and a hell of cunnilingus near-climax teasing. Despite the "no ejaculation" rule, he ends up having multiple consecutive ejaculations. Anxiously, he asks, "What's going to happen to my penis?"
