Why Did I Do It

I have been married 8 years to a very good man. We have much fun together. Totally satisfied with our lives. We are ready to start having kids. Sex is good and often and almost daily. This past new years we went to a casino to celebrate. We said we hoped to not have the opportunity next year and hoped to have a new baby.
We gambled some and were hanging out dancing and drinking. I hadn’t drank much but was feeling good. She midnight happened everyone was kissing everyone. I got separated from my husband on the crowded floor. A tall good looking man approached and gave me a kiss. He kissed longer than the others and I liked it. He stated he had been watching me and had something for me. I smiled and we had an intense kiss and he squeezed my breast. Again I liked it. He took me to the edge of the dance floor and we kissed some more. I haven’t even looked for my husband. He took me by my hand and took me to the elevator. We got off after going up a few floors and went into stairs. We started kissing and fondling. He have me highly aroused. He unzipped his pants and I had to have his cock. I went down on him but he stopped me shortly and pulled my panties aside. We had standing sex while balancing with handrail. I was having many orgasms. When he orgasmed he tensed up and released deep inside me. He pumped until he softened. We straitened up and returned to the dance floor. I found my husband. He said he had been looking for me. I accused him of enjoying kissing other women to much to find me. I told him I went to bathroom. We left to go home and I told him I needed to go to bathroom again. I had to clean up. I was amazed at how much cum was in my panties and running down my legs. This man really needed a release.
This sex exsperience didn’t give me guilt until weeks later. My husband is totally into me and shows how much he loves me. I can’t believe I had sex with a man I didn’t know and unprotected. I had a std test after a month to eliminate my fears. I was clean. I have guilt sometimes for what I did. My husband is my life and I cheated on him. I have no reason to know why I did it. The thing that haunts me is that the final orgasm I had when I cheated is no doubt the biggest I ever had. I almost collapsed but the man held me up. I think about that night almost every time I orgasm with my husband. My mind should be on my husband instead of my cheating fling. I will never forget him tensing up and feeling his penis pumping inside me. I will take this to my grave and will not cheat again.
