I am reading a book when my brother walks in complaining about how I gave him a hard-on. It takes a little sweet talking, but I'm easy to flatter. I realize our parents are heavy sleepers so what is the harm if I watch you? Just no touching. I encourage you to play with yourself, play with your balls, and eventually encourage you to cum all over your sister's big tits.
