S1 exclusive actress Shion Yumi loses her senses and dives into new sexual pleasures. To let her experience a climax unlike anything she's felt before, a special rule is imposed: a full month-long ban on masturbation and sex. As a result, her nipples and pussy become extremely sensitive from complete lack of stimulation. By the time she arrives on set, she's already in a state of extreme hypersensitivity. The shoot begins with aphrodisiacs, slowly teasing her to the edge. Her nipples and clitoris are constantly stimulated, driving her toward endless orgasms and involuntary urination. Here it is—the intense, nonstop sex brought on by abstinence and the effects of aphrodisiacs, unleashing a relentless series of climaxes.
