Mao Hamasaki is highly sensitive to her superior's scolding, involuntarily urinating herself from just a single reprimand. Each time she wets herself at work, she's punished with spanking, and even when her pussy is plugged with a vibrator, she erupts in a fountain-like orgasm. To keep her secret from coworkers, she allows them to grope and toy with her body, dripping female juices as she's fucked in the office, experiencing creampie orgasms and massive squirting. During a tense client presentation, Mao loses control and urinates again—forced to offer her body as compensation, she's made to perform titty fucks to get her boss hard, is taken in 69 position, and gets doggystyled until the intense pleasure triggers yet another involuntary urination. Each incident drives her into an uncontrollable urge, completely robbing her of self-restraint.
