I'm so unlucky with women, but I really want to see a woman's genitals! With that single-minded desire, I sneak into my sleeping sister's room, pull down her panties, and admire the raw vagina! Naturally, I get an erection! I want to insert it, but I can only rub against it and hold back… until my hips start moving on their own, trying to penetrate my sister's wet vagina, resulting in a full penetration! Then, she continues to pretend to be asleep and makes me ejaculate inside her!
