Barging into your sister's room at night without knocking is a bad idea. Or maybe it's a good idea if your sister is of a liberated disposition. You've come to me with a very delicate problem. Tomorrow is your first date with a girl, and you're still a virgin, you're embarrassed to do anything wrong. You ask me to take your virginity and show you how to fuck. I'm in great shock and confusion. I don't know why, but I got so turned on by the idea. I felt my panties getting wet and I realized it was a sign. A sign that I really wanted to live this experience and be my little brother's first woman.
