I was away with two other couples and one night we were watching the US Open Mens Tennis. Everyone started to go to bed till I was watching with my friends wife. We were both sitting on the same couch. Her foot was touching my thigh and rubbing it. I kept readjusting myself thinking it was just a mistake she did that. But she keep doing it and she finally moved to rub my crotch. My cock got hard instantly. I looked at her and she licked her lips so I opened my shorts and she was sucking me like a hungry dog. The next thing I knew she stood up and removed her shorts and jump on my cock and rode it. After she got a tired I flipped her on her back and just rammed my cock deep in her. I fucked her good and hard till I was ready to blow and her legs wrapped around me so I blew my load deep in her. We stayed in that position for awhile enjoying what just happened. I got up and she grabbed my cock and licked it clean. I left to go to bed with my wife and she went to bed with her husband. Our dirty own secret
