Sins of Lust Ch.1

Our main character is chronically ill and the doctors are concerned about his health. They conduct several tests as they try to figure out what's going on with him. They come up with different diagnoses but none seem to fit. The main character produces excessive sex hormones but he is not easily aroused like his companions. Nothing excites him not even sexy babes. The doctors do not understand this phenomenon and are determined to stimulate his sexual desire. They advice him to build a harem of sexy women who he can fuck and maybe they will be able to remove his sexual charms.
