Her and her brother were home alone and they start reminiscing about old times, when she notices the covers moving next to her…..he is having off right next to her! She should be disgusted, but instead she is intrigued. She’s never watched a guy masterbate and is kind of inexperienced. She decides she wants to take the opportunity to learn and watch so when she has to do this to a guy, she is more prepared. He talks her into also touching herself. She is very aroused by this idea. They both decide it will be their little secret as they discover their bodies with each other.
