It seems my brother's wife doesn't like doing it. He said he already talked with her and she was shocked so he never tried to bring the conversation again. I've been doing it since he told me a year ago. My brother already asked me if I had sex with him. I'm not sure. I told him would think about it because I really get very wet while I milk him. Sometimes he returns the favor and we almost had sex several times but I always back up in the last minute but I don't know for how long....
