Hi. My name is Nicola and I've searched for a place to tell my story where no one knows me. I need to share this becouse its so unlike me to behave like this and I need to tell someone. Firstly let me tell you about myself. I'm married with 2 kids, I'm 41 and I think I'm still in good shape even though I say so myself. The only thing I don't like about myself are my tits, they are a bit big (DD) which some say is a good thing but it tends to lead guys to talk to them rather than me and becouse I'm quite slim and 5'5" I think they look out of proportion. Anyway, we all went to Florida in July and had a great time. With was our friends Robert and Julie ( not real names of course). We have known them for a couple of years and get on well. They have a little boy who is someone for my two to play with on holiday. Robert is a bit of a flirt and quite good looking but harmless enough. Anyway onto why I'm writing. It was half way through our holiday we had all finished dinner and the kids where in bed. After a couple of bottles of wine the conversation turned to who had done anal and who hadn't plus other sex talk. My husband was disgusted at the idea of anal but it was clear Julie and Robert where quite into it. Anyway hubby changed the subject and I decided to go into the pool becouse it was still very warm, Robert joined me but hubby and Julie decided to wash up and just chill in front of the TV. The pool is right next to the living room with sliding doors connecting, the blinds meant you couldn't see much of the pool unless the lights where on but you could see into the living rooms with its bright lights. Robert was his usual flirty self and a bit touchy feely. I moved to the side of the pool and looked into the living room, my husband and Julie where watching the TV on separate chairs but both starting another bottle of wine. Robert moved in behind me talking nonsense about how hubby and I should try anal and how I would love it. I wiggled my bum and said something about always wanting to try anything once not really meaning it, it was just something you say. Robert pressed up against me which I thought was funny so I wiggled again, he put his hand round my waste and whispered 'you really should try it'. It must have been the wine becouse his hands squeezed my bum inside my bikini and I said nothing. I just stood there in the pool looking at my husband as Robert pulled down by bikini bottoms, I reached behind me and gave his shorts a tug freeing his cock. I stood watching hubby and Julie having a laugh at something wondering if the kids where still asleep whilst Robert put his hands on my waist whilst pressing himself against me. At first his cock just pressed against my bum hole and then it happened. I love my husband so much and had never even thought about being unfaithful before but now I was letting another man slid himself into my bum. At first it hurt but as he gently thrust deeper and deeper the feeling was amazing. For a while I watched the living room carefully in case they decided to come out but soon I was past caring, Robert was fucking me up my arse getting deeper and deeper until I could feel his balls against my bum. My bikini top had come off at some point, not sure when but I really didn't care. By now Robert was squeezing my tits and banging me like a rabbit. I told Robert I was going to cum and must have said it a bit too loudly, he put his hand over my mouth just in time to stifle a scream. How the others didn't know what was going on I will never know, Robert was grunting, I was screaming, all be it stifled and was was splashing everywhere. Then I felt Roberts cum shooting inside me, it was hot and there was a lot of it. Robert had to hold onto me becouse my orgasm was so strong I couldn't stand, I felt his cock getting smaller inside me until he slipped out. We quickly put our stuff on and left the pool quite sheepishly. Robert joined the others but I went to bed having to visit the loo several times to wipe cum from my hole which was a little bit sore but I was hooked. I'll tell you the last part soon.
