My partner and I had been dabbling with MFM sessions through Swinging Heaven, but although we had always asked for well endowed men, we never seemed to get beyond some charming men attached to no more than seven and a half inch cocks. Out of the blue, we were contacted by Steve, a middle aged guy from just twenty miles or so from us. We arranged to meet Steve at a canal side pub,late summer so when we met at eight the light was already dimming. Steve was very pleasant, made me feel very horny in anticipation of what would happen later (although from previous experience, I was expecting no more than my boyfriend could offer in size). After a couple of 'lubricating' drinks, and some talk of previous encounters we were all in the mood for a walk. We left the pub and started a walk along the canal path, the only light was the moon giving a beautiful soft glow to Steves face as my heart pounded in expectation. My partner and I had already walked along the canal path earlier to plan where we would stop and get down to some activity, but we had walked only half way to where we had agreed, and I was so horny I stopped and said 'here, that's far enough'. Steve took hold of me and started to kiss me passionately; he immediately grasped my breast through my thin top and made me groan with pleasure as he did so. I couldn't resist feeling his bulge through his trousers, it was impressive, but I wanted it in my mouth. We were still kissing as I nervously undid his zip, and released his huge (yes huge) cock from his stretched boxers. I immediately groaned and went down with my mouth to suck his at least 9" cock which was thick in proportion. I love giving oral, but we were in the middle of a canal path and I was dying to get that beautiful cock inside me; like a child who thinks they will have their sweets taken if they don't eat them quickly. I reluctantly removed his huge cock from my mouth, licking the end as it left me. I immediately turned around and bent over as if to offer my aching cunt to this monster, Steve wasted no time in easing my thong to one side and easing his gorgeous nob into my aching hole. It was the most amazing feeling I have ever had, he pumped me so hard and so deep, I had cum within 30 seconds, but he continued his perfect rhythmic pattern for another five minutes, not the longest session I ever had but I was dizzy with sexual extacy, I could hardly see.... he pumped harder and harder as he began to orgasm.... I screemed as he filled the condom inside my tight fanny. Oh I loved that night, I completely ignored my boyfriend during the whole sex session, he doesn't mind and just loves to see me enjoy myself.I must be honest though, up until now, I have never told him just how special that night was, but I bet he won't be surprised!
