My wife Sandy and I had done several mfm threesoms and were looking for something new to try. We decided for her to have an affair with someone that I knew and not let the guy know that I knew. I knew a lot of guys and Sandy was a tall well built redhead so it was a matter of picking someone. I had a young guy named Fred working for me and we had become friends. He was single and had no problems with the ladies because he was a nice looking guy. I set it up to send Fred to my house one afternoon to wire some speakers for me. I told him that Sandy would be home at 3 pm to let him in the house. At 2:30 I rushed home and parked my car A block away. When Fred rang the doorbell I went to the bedroom closet and got undressed. I had a good view of most of the room and it was daylight so I had plenty of light. Sandy was in a short housecoat and had just got out of the shower. FRed worked while she got him A beer and carried on a conversation. She was sitting on the bed and her coat kept coming open. He was definately intrested and the talk got a little sexy. She was facing me and I knew by now that he had a great view of her pussy.She took the lead by asking him about some of the girls that he had dated.She said that she had always liked to dat around but being married had slowed her down some. He admitted to dating a couple of women that were married and liked the thrill of doing it. She got up and let her housecoat drop. She said we have at least an hour before my husband gets home. He had his clothes off in less than a minute. They did a 69 on the bed and she was looking right at me as she bobbed up and down on his dick. He was about my size and she was taking his whole 7 in down her throat. He had to get up to keep from cumming. I was ready to cum also but held it back. She got on her back and he went all the way in then started to pump. He pumped A long time before she wanted to change positions. She got into position for him to mount her doggie style. He shot his load in her pussy while she shot her own load. She had gone a little wild. He cleaned up while telling her how great it had been. I saved my load until he left.
