I'm married and have 3 children with my wife. We have a strong relationship, minus the sexual part. My wife has been going through menopause and is never in the mood. I cheated on my wife this last weekend. My work had a late christmas party. They rented out a backroom at a local restaurant bar for us. I ended up going solo as my wife opted to watch the kids so I could attend. It started out with lots of food, some corny games and then some gifts. About half the people then headed out. The rest of us started to drink, dance and have a great time. I ended up dancing with Mary, who is a receptionist in the office next to mine. Mary is in her mid 50s, brown and light grey hair, very fit, blue eyes and decent looking. We got quite close but nothing happened on the dance floor. Mary then asked me to do some shots with her. We did a couple rounds of shots together. She asked if I wanted to go outside for some air and I said sure. There was a door to the back patio area in our area. We walked out there and could still hear the music. Mary asked me to dance some more again. We started to dance and got close again. She leaned in and pecked me on the lips and smiled. We kept dancing and she turned around. I ran my hands across her abdomen and up her body just under her breasts. She had a very toned nice body. She leaned her head back on me and we kissed. As we were kissing I felt her hand start to massage my cock through my pants. Mary turned around and she kept rubbing me as we kissed more. She looked around and pulled me. There were a couple stacks of patio chairs in the corner. She pushed me back in the corner so we were out of view. She got down in front of me and unzipped my pants. She looked me in the eye as she pulled down my pants and boxers. My cock sprang out and gently smacked her in the face. She laughed a little and then lightly wrapped her hand around it. She told me I had a nice cock before wrapping her lips around me and started to suck. She was amazing at giving head and I was honestly dissapointed because she ended it so quick. She stood up and pulled down her leggings and bent over for me. I got behind her and spit on my cock. I fucked her from behind and really pounded her. She came hard and told me to cum in her. It didn't take long and I ended up cumming inside of her. I kept fucking her a while longer before we got dressed and headed in. We ended up at the bar. I ordered more shots for us. I ended up sharing an cab with Mary. We made out and she ended up spitting on her hand. She put it down my pants and gave me a hand job on the way to her place. When we arrived she had me so hard and ready to bust but she told me she had to go inside alone. I ended up going home and sneaking into the bathroom to release before going to bed.
