When you contract this disease, it becomes impossible to repress your sexual arousal. You head to the hospital with a light fever and are given a diagnosis with a shocking name: Lewd Crest Syndrome. A disease that causes a peculiar pattern to become visible upon the skin above the crotch and induces a state of constant sexual arousal.
The only means of curing this disease: "Sex." As you are a virgin without a partner to provide "treatment," the doctor makes an astonishing proposal.
