Joan makes a friend

I was meeting an old college friend for a quick drink that was in town for a few days. I invited Joan along to meet Paul as she had nothing else planned that night. I could tell right away that she was attracted to him and when he excused himself for the restroom she asked me if it was OK to fuck him later. I totally agreed and gave her my blessing. So we invited Paul back to our house for a nightcap. Joan explained to him that it was a weeknight and we had to get up for work the next day. So I opened up a bottle of Cabernet, Joan said she was gonna put on a more comfortable pair of shoes and as Paul and I sipped our wine, Joan came out wearing a very sexy red teddy. She walked right over and sat next to Paul on the couch and quickly explained to him that she wanted to have him. I explained to Paul that it was OK as I was just going to be an observer. They quickly made out and Joan got on top of him straddling his hips . She reached down and un did his pants and unzip his fly to reveal a very beautiful 7 inch cock, Which she quickly pulled it out and begin stroking. She then got down on her knees and begin giving him a blowjob of his life. After about five minutes she quickly stood up and led him to the bedroom where he quickly undressed. They made out a little bit more and Joan climbed on top of him and took him inside her inviting moist pussy. She rode him well and after a few minutes he got on top of her and she wrapped her legs around him taking him missionary style. This went on for about 10 minutes and I can see the look on Paul's face as he was beginning to cum. After he came, I could tell he was a little uncomfortable with the whole situation and quickly left. Joan loved the whole experience telling me how beautiful his cock was as I cleaned her out.
