It all started by accident but it was so good we do it again and again. I've always felt there's something wonderful about wearing a little black dress, seamed black stockings, black high-heels and nothing else. So when I found myself at a wedding my husband had dragged me to, to avoid insulting a wealthy client, I dressed sexy and drank to match. I know they say that martinis are like breasts - one is too few but three are too many - but I must have been well into my fourth when I noticed a man who was so sexy I started juicing while I was leaning against the bar. I had to have him. I knew I was married and I knew that I'd promised to stay faithful. In fact, to that point I had stayed faithful. But all that went out the window. Four martinis and a very few sexy clothes had me feeling like a tramp. As I walked over to him I could see that he'd clocked me and liked what he saw. Looking back, I think he probably thought I looked quite drunk and I wonder whether that encouraged him to have a go. We spoke for a few minutes, although I can't really remember what we spoke about, just that he asked me whether I'd like to go upstairs to his room. There was no hesitation, I just took his arm and let him led the way. We walked into his room and and fell onto the bed. The sex was fast, furious and messy. About 45 minutes later I was desperately trying to fix up my makeup and cursing my laddered stockings before I hurried downstairs in the hope that I'd not been missed. I'd been missed. Everyone had moved from the cocktail reception to the main hall and the waiting staff were taking away the soup bowls and starting to serve the main course. As I took my seat next to my husband I tried desperately to think of an excuse for being so late but realized the smell of sex probably made any excuses fairly pointless. Everyone was very polite and no-one said a word about it but the meal was very hard going. As soon as we could leave we did and as soon as we got into the car he asked me who it was I'd had sex with and whether he'd cum inside me. And the surprise was that he didn't sound angry; he sounded horny. Very horny. I had to admit that I didn't know his name and had to describe him and admitted that he'd cum inside me twice. We drove a couple of miles down the road and parked in a lay-by. I got into the back seat and lay down with my legs facing the edge of the curb and my husband knelt between them and licked and sucked at my still very wet, juicy and very fucked cunt. We were both very, very horny and we both needed to cum and I came twice before he climbed on top of me and added his own sperm to my cheating cunt. The rest of the weekend was spent in a constant state of sexual tension. If we went more than two hours without licking, sucking or fucking each other it was because we were sleeping. I'd never intended to cheat on my husband but when I did it kicked us into a new realm of sexual interest. I suppose the forbidden is always highly desired but I think my husband also loves the risk element. Some men love to gamble on the horses and I think he gets off on the risk that one of my partners will knock me up. I say partners because this is what we do now. Several times a year we book into hotels that host weddings and other big parties and I put on my little black dress, stockings and heels and crash the receptions, looking for someone to fuck me. When I find them I take them back to my room and have a couple of quick fucks before they have to get back downstairs again. As soon as they're out of the room my husband comes in and sucks the cum from my unprotected pussy before he fucks me himself and pumps his own sperm into my womb. We don't make an effort to schedule these little weekends away while I'm at my most fertile but a couple of them have been, including the last one. It was about 10 weeks ago and I've missed my last two periods. Time will tell.
