I am a 36 year old married woman and up until two weeks ago I had never been unfaithful to my husband and even now, when I thing back at what I did, I never agreed to have sex with anyone else, it just happened, but what is more shocking is the fact that it was me that instigated it and it was just sex with someone else, it was sex with another couple, people I had only just met. We had been on holiday to Florida, we hired a villa and had a great time. Our children loved the parks but after two weeks of constantly on the go I was tired but they just wanted to keep going so I agreed that my husband should take out three children on his own, they are 10 years of age and an 8 year old and well behaved to I was happy for him to do so. They left early so I took advantage of the time on own to relax and sun bathe. I had seen the couple next door but had only said hello and given a wave, nothing more. I had however noticed that they were a very attractive couple, older than me and clearly American and for some reason I was strangely attracted to them. I caught myself sneaking a look over to them and once and a while they would catch me looking and wave and I would, embarrassed that I had been caught, wave back. This morning I could hear them talking and laughing and couldn’t help myself but look over towards their pool, this time they were looking over at me, she called asking if I had been left all on my own. We struck up a conversation and I explained that they had gone out for the day and I was looking forward to having some ‘me time’. I felt terrible that I had just told strangers that I was looking forward to not having my kids around, but they laughed and said they understood. Foremost of the morning I lay on the sun lounger, I took the opportunity to take my top off and half dozing found myself touching myself thinking about the man next door, my hand between my legs, masturbating thinking of having a man other than my husband inside me, in my mind the picture was of the man next door. I was brought back to reality by the sound of a door closing, like the one that leads out form the pool screen. My hand shot out from between my legs just in time to see the women next door who I later found out was called Mary looking through the mess. I lay there topless, my tiny breasts on show whilst Mary asked me why I wasn’t over there with them and insisting that I joined them. A wrap that she had round her didn’t hide the fact that her breast where a good deal bigger than mine. She didn’t accept my initial refusal but instead managed to open the screen door to come and stand next to me. I told her I would get dressed and be over in a minute, but she wasn’t having any of it, she walked over to a chair that had my t short on it and threw it to me telling me not to bother dressing and that I was fine and to just throw that on (my t shirt) whist I walked over adding that I looked just fine as I was. For one horrifying moment I wondered how long she had been standing there and wondered if she had seen be masturbating. What happened next still shocks me, more that just the fact that I had a threesome with strangers is the fact that it happened so quickly and without a conversation leading up to sex, no hints, no sounding out if I was into doing that sort of thing, I was just laid on my back, undressed and had a large thick cock thrust into me. I walked over the 12’or so distance between our two villas and though the door into their pool area. They had hedges surrounding their pool so there was some privacy. In the few seconds that it took for me to get there, led by the hand, I was told that to was their own villa and that they spent a lot of summers there as well as being showered with complements such as ‘you’re so beautiful, you shouldn’t be on your own, and then but that made me think I had been caught touching myself, ‘ you should not have to entertain yourself’. As soon I as entered their pool area, I was shocked, he was laying there naked, his semi hard cock hard not to miss. Mary told me not to be shy and that they rarely dressed, unless they had neighbours, ‘come on now honey, take this off’ . Mary pulled at my t short pulling it off over my head, I was topless in front of a naked sexy man, Mary undressed and in seconds was also naked. I was embarrassed by how fit and athletic they looked, I am not over weight, in fact I am a little skinny if anything but they clearly worked out and I felt I had to suck my stomach in. I was led to a sun lounger, Mary asked her husband to confirm how sexy I was whilst she put her hand on my tummy, ‘ I told her that she didn’t need to pleasure herself’ . That was the moment I knew they had seen me masturbating and my face burned up even more so out of embarrassment that I had been seen than the hot sun. Mary said that I should not hide myself, her hand slid to my breast which she cupped, He knelt next to me and I knew immediately that they had an agenda. Mary repeated that I shouldn’t hide myself and tugged at my bikini bottoms. I instinctively grabbed them, but she told me not to be silly and pulled them off. I glanced at myself hoping that I had remembered to shave between my legs, I had missed a day, but it wasn’t too bad. Then they did it. Mary kissed my cheek telling me again how pretty I was, then as though she was judging flowers pressed my nipples between her fingers and said to her husband ‘ aren’t these adorable’ he said that everything about me was adorable, Mary leant down and suckled on my breast before taking one fully into her mouth and sucking, I felt her tongue flicking my nipple, her husband knelt between my legs which he had opened. I remember thinking ‘what are they doing’ and whilst one side of my brain was protesting the other half was half way to an orgasm, I had that warm tight knot in my stomach my husband used to make happen. Her husband lifted my knees and my pussy lips with his fingers, his tongue hit the spot, he knew exactly where to suck and run his tongue. Mary lay the head of the sum bed flat and returned to sucking my nipples before her tongue entered my mouth and her hands took the place of her mouth. I decided fi I was going to protest that it should be now and I moved my head to catch my breath, I said far as far as ‘erm’ before Mary said ‘ that’s fine honey, just have some fun’. Her husband knelt between my legs, I looked down as he held his cock and pushed it towards my pussy and in one swift move, he pushed himself into me. The thickness of his cock stretched me and the it went in deeper and deeper until he pulled back and started to slowly thrust himself in again and again. Mary ran her tongue over my lips and occasionally into my mouth, whilst her squeezed one and her husband squeezed the other breast. I have no idea how long it lasted but for some time I had sex with a stranger, his cock thrusting into me over and over slowly at first but over time gaining speed until he fucked me hard. I must have been groaning loudly because Mary laughed and told me to shush covering my mouth with her hand. I could hear myself crying begging him to fuck me hard, and to keep going. Mary put her breasts to my mouth and told me to ‘have a nice suck’. Her large breasts smothering me I sucked her hard, her milk on my tongue. I must have sucked her too hard because she squealed in pain and pulled back. Her husband was fucking me hard now and I was telling them I was going to cum, Mary asked me if I wanted him to cum inside me, I begged him to cum in me hard. It was as though she was directing the whole thing, I just lay there, my legs open wide and her husband thrusting himself into me over and over and I had the first of several deep orgasms, she said to her husband ‘ok dear, cum inside her now’ and something about filling me with his beautiful seed. On que, he let out a groan and I felt warm cum flowing into me and I cam again, hard and deep. After a dozen or more thrusts and a few more spirts of cum he slid out and Mary replaced him between my legs and rubbed her pussy against mine. Another first, I had just been unfaithful to my husband and now I was having lesbian sex and it was great. Mary knew exactly hat to do to make me cum and fuck did she. Gripping my breasts to hold me in place she fucked me hard climaxing with me. Then it was over. After I managed to catch my breath I dressed. Between my legs was sore as where my nipples, I told them I had to go before my family come back. They both said how great it was and that they hoped I would come back before we leave for home. I went back m my villa and showered not believing that I had just had sex with other people. I went to bed and slept for a good few hours before getting up and getting in the pool. Later my family returned, and I rushed to check my body for marks but thankfully there were none. Three days later my husband took the kids to get ice-cream, Mary called out ‘honey’ and held the screen door open. The thought of refusing lasted moments before I ran over and let them drag me to the bedroom and ‘had me’ , cum filling me again. The day before we left was the worst time, I felt so dirty and guilty. Mary had made friends with my family and whilst I finished packing, she came to the villa, the kids shrieking and laughing at her visit, she had got them on her side. She said that she wanted to show me a dress she had bought and asked my family if she could borrow mommy. Hy husband said’ yeh go, the kids shouted for me to go. I knew that she wanted, I felt guilty and told her I had to stay and pack, Mary grabbed my hand and told me that it would be quick and pulled me away. I said that it had been a nice experience, but it was wrong, but they insisted that having fun was never wrong. This time I was wearing a skirt and blouse which was soon open with a her husband’s mouth latched onto my breast with Mary pulling my knickers down. This time we were in the lounge next to a window with blinds. I bent over the end of a chair and let him enter me from behind and as I watched my family play in the pool a familiar thick long cock was thrust into me. My view was thankfully blocked my Mary and she fed her breast into my mouth as her husband fucked me from behind and as I sucked her breast, he sucked her mouth until cum flowed into me for the last time and I climaxed hard yet again. Then like long established friends, we hugged, and I went back to my family. I left Mary, with her large sweaty breasts and her husband with his wet cock in her hand. As I slid thee French doors closed, I heard her let out a deep gasp and I knew he was inside her. I came close to going back in to join them, but I did what was right and went back to finish packing. That was my one and only adventure and I am sure it will be my last. Adventures like that only happen once in a lifetime and whilst I feel guilty, I also feel liberated, happy that I at least once in my life did something for me.
