I caught my brother spying on me when I was going to the bathroom. Afterward we're sitting on the couch and I keep noticing him looking me up and down. He's a horny little hormonal teen so I try to ignore him. But he keeps staring me down and it seems kind of creepy, but also kind of exciting. I finally learn that he has no experience with women. So I do the good big sis thing and decide to take this opportunity to teach him a little bit about how to please women. I describe the anatomy and demonstrate what feels good and what will make any woman instantly wet to the point of an amazing orgasm. The lesson gets cut short when we hear our mom pull up in the drive way. This is part one of two of a brother/sister fantasy. This is part of a more natural video sequence. One take and no professional lighting. Check out Part 2 to see where it goes from here. Custom request from one you amazing fans!
