I was out at the mall one day shopping. I turned the corner aisle in the department store I was in. I happened to see a family friend Nick, and he was with someone who wasn't his wife. Nick and his wife Liz were friends of my wife and I. This woman who he was holding hands with and kissing was in her early thirties, from the look of things. Nick and Liz were in their mid-fifties.
I quickly hid myself so I wouldn't be seen. I walked back down the aisle I was in and out of the store. A few weeks later my wife had me run over to Nick and Liz's house to drop off some items for a party they were going to have. Liz was alone and let me inside.
Liz was somewhat short, with short, dark hair. She was a little bit overweight, but she had big tits. Liz was standing at the kitchen sink talking to me. I am not sure what possessed me, but I placed my hand on Liz's ass. Liz asked me to remove my hand. but I didn't.
"I know about Nick and his woman," I blurted out.
Liz turned to me and her eyes got big. I figured she must have suspected her husband was stepping out on her. We were standing so close now, you could not have slipped a piece of paper between us.
Liz leaned over and kissed me on the lips. From there we sort of went crazy pulling each others clothes off.
When my underwear came off, Liz let out a gasp. She caught sight of my cock. I was blessed with a nine incher, and it was dangling between my legs.
"My God it's huge!" Liz told me. "Nick's cock isn't half that size," she said.
Liz put her arms around my neck and then I lifted her up and took her to the dining room table. From there I started to rub the length of my cock across her clit. Liz was moaning and beginning to get very wet.
