This happened almost 20 years ago, about 3 years before I met my wife... I had known Helen for almost a year. She was a gorgeous brunette with a pretty face and a killer body: Sexy and with an ass and tits to die for. And like too many girls like her she was a little vain, insecure and egocentric. But with her looks she overcompensated for any lacks in her personality.

One day, after a horrible day at work, I stopped at a bar on my way home to have a couple of beers before crashing in. After that first bar I went to another and then to one more. By the time I got to the third bar I had quite a buzz going. As soon as I go in I see Helen talking with a bunch of guys and acting odd.

A couple of days after I find out that she had found her boyfriend cheating on her with a friend of hers. She had called a mutual friend of ours to ask her to come there and console her but she could not make it (she had shift at the hospital). So what did she do instead of going home? She let guys buy her drink after drink after drink. By the time I got there she seemed to be a bit dizzy. After I went over to her, deducing that she had just met all of these guys and finding out that she was there alone (she said that Sandy - the friend that to work shift at a hospital - had stood her up) I offered to take her home in a cab. Her flat was on the way to my place. But we stayed for a couple of drinks and talked for a while before leaving. She never told me about her boyfriend's cheating.

We were both drunk and started flirting with each other. In the cab things got a little more intense and we kissed. When we got to her place she asked me to come up for a nightcap. As soon as the door closed we jumped on each other and started making out in the most intense and animalistic way I have ever experienced in my life. Of course, we had sex, the best ever in my book. I remember it so vividly as if it was yesterday.

The next day when I called her she had absolutely no recollection of anything that happened short after I met her at the bar. I did not tell her that we had sex because I felt a little guilty even though I never suspected that she was that drunk. And I checked with Sandy who confirmed that Helen did not remember a thing of our flirting or anything else between us.

I left it at that and never mentioned what happened to anyone. And I did not pursue Helen because of her complicated love life at the moment and also because of her personality. As much as she physically turned me on, I couldn't imagine myself in a serious relationship with her. So, 3 years later, Helen introduces me to her older sister. We fall in love and marry. No one besides me knows about this. And to make things worse I can't help but think about the sex I had with Helen. It's getting worse year after year. It's torture to look at her, who has aged beautifully (so has my wife). I hope that by writing this I can get rid of this demon. But I fear it's too late.
