A man whose sperm volume is abnormally high and whose erections won't subside. After an investigation, it's revealed that he has a rare constitution found in only one in tens of thousands, leading researchers to want him as a subject. The female doctor is amazed by his extraordinary recovery power, no matter how many times he ejaculates. One day, during a procedure, some semen accidentally splashes onto the doctor's face, and the skin where it landed becomes smooth and silky. They discover that his cum contains an outstanding amount of components that have a skin-beautifying effect. From that day on, the doctor begins to squeeze every drop of semen out of him through semen collection and facials, driven by her own personal desire... A total of 18 massive facials! Momo Sakura happily and with a smile, takes in all the cum!
