I've been having sex with my brother before he met his girlfriend and we were able to make her accept our relation, so we are now a threesome. My brother does me and his girlfriend and we have a great time together. We planned a weekend at our granny's house. The house is empty and it's close to the beach so we like to be there when we have time. Last time after we arrived my brother's girlfriend got a call from her parents saying there was some kind of a problem and that she needed to go back. She only stayed one night the rest of the weekend was only me and my brother, like in old times.
