Her friend was down from York and my ex invited her to stay with us for a short period while they were flat hunting. She brought her 6’4”, slim, g...od looking b/f as well. One night (his birthday) we got a bit drunk with some friends and family members. Walking home he needed to rest so did so on a low wall on the boundary of a then empty hospital. We ended falling over onto the grass the other side. After laughing for a few seconds I suddenly felt him unzip my jeans, pull out my semi hard cock. This time he wanted to see if he could really pass as a girl his own age. He had even gone to the length of making out a list of things he needed, writing them in a curly fluid feminine style. This was going to be a special time. His mother had just gotten some new makeup that week. She looked better then ever with it and he wanted to try it out for himself. He took the notes, borrowing his mother's car the evening after his parents left for the weekend and headed to the mall. The first stop. “Oh Will! I’m cumming again! Oh son! Yes! Your juices feel so warm and gooey inside me. I love it.” My cock finally went limp and I slid it out of my mom’s pussy.“Mom, I know I’ve said it before, but now you truely are the best mom ever. I love you so much.” I said out of breath.“I love you too Will, and your not such a bad son either”We fucked three more times that night. I came inside her every time. It was a good thing it was the weekend because we were both exhausted the next day. It was. I figured she also wanted to spend some up-close-and-naked time with him too.I made the call and Albert was delighted to hear from us. Of course we were welcome to the celebration and could stay at his house. His father lived with them now too. Courtney had told him about her gift idea and he said that he thought his dad could accept it one way or another.We settled into the guest room and had a nice dinner with plenty of beer and wine. I wondered what would happen at bedtime. Dad’s birthday.
