He had called and answered our ad. My wife had placed an ad in one of those swap sites online. She wanted to meet a stranger who had come to town on business; meet him in his hotel and fuck his brains out. She got her wish. She drove to Dave's hotel last night around 11 pm. I followed. When he opened the door, the exchanged greetings, he leaned over and kissed her on the cheek and she went in. I slipped up to the door and peeked through the curtains in the window and watched. He put his arms around her waste and kissed her, pulling her closer into him. She dropped her purse on the floor and put her arms around his neck. He grabbed her ass with both hands and pulled her tight into him. Pulling her skirt up high above her ass cheeks, I coulds see her red panties. I was rock hard. Next thing i saw was Dave throwing my wife on the bed and ripping her close off. He slapped her hard when she tried to protest and she started to cry. I got more excited. The next thing I saw was this guy ramming his cock into my wife and slapping her hard. She finally gave in and stopped fighting him off. When she relented, Dave really started pounding her pussy. From my angle, I could see his big hard cock ramming in and out of my wifes pink hole. She reached around and grabbed his ass and pulled him down on top of her. He rolled her over and rammed his big cock into her ass and fucked her just as hard. I saw him haunch his back and he came inside my wife's hole. She loved it. Got up after a few minutes, dressed, and left. I raced home ahead of her and she climbed into bed with me. She never knew I had followed her. The next day I asked if she had slept well. Her response was "oh baby did I" We 'rent' a big cock now and then to fuck my wife regularly.
