My wife's step-mom has always given me flirty eyes whenever she was around me. The sexual tension between us had been building for years and this weekend my wife was out of town when her step-mom asked me to come over and help her move something. When I came in she was waiting for me on the bed wearing a very sexy red lingerie set under her clothes. I couldn't wait to fuck her! Includes almost every position possible, me going down on her, her sitting on my face, fingering, masturbation, making out, etc. It was an absolutely amazing experience!
