Carly told them to stop bugging me besides they wanted to talk about guys and she didn't want to have her brother to hear them. One of her friends s...id that I was a hottie and just because I was her brother didn't mean they couldn't talk about me. Carly argued but lost the battle with her friends and I sat down and had a drink. They started asking me different questions about girls and what I liked for women to be like.

He loved beating off - the feel of his teen spunk shooting was.
