Sister is curious

You laying on your bed and music is on. If you close your eyes you have still images from that what happend.

You thinking about it over and over again. He was standing there. Pants done. His penis standing straight away from his body and this unbelievable big nutsack. You allready seen the nutsack from him as you was younger. Also you have seen your father's a couple of times too. U realize that you opsnd your eyes and that your jaw droped open. That was his ballsack under the cock. First you thought he had a pillow squeesed between his legs but now you understand. Your brother has fucking damn huge nuts.
