The pure white beauty of Sakakibara Moe is offered to 20 hungry men. After being given an aphrodisiac, she is subjected to a shocking orgy that continues nonstop for 12 hours, from morning until night. Cocks are replaced one after another, and the pistons continue relentlessly pounding into her uterus. Her body is sticky with semen and love juice, and even though her consciousness is hazy, she is forced to orgasm repeatedly. The sight of her arching her back and screaming as she accepts the semen of 20 men is a state of extreme pleasure. This controversial work depicts the fierce battle that unfolds over 12 hours as a young girl's dignity is swallowed up by the murky current of desire and she is completed into a "flesh urinal."
