I've been an extreme germaphobe since I was a child... I don't want my friends, or even my family, to enter my room. One day, when I came home, I found my sister on my bed with bare feet, eating, drinking, and dropping food scraps all over the place, and I nearly fainted. Then, instead of apologizing, my sister said, "I'll cure you of your germaphobia♪," and took off my virgin pants, played with my dick, licked it covered in saliva, and even put it in my pussy. I nearly went crazy, but in the end, a lot of white sperm came out.
