I first dated my girl-friend 4 years ago but before we got together I kept bumping into her when I was out walking or driving. we smiled and walked-on. I didn't think I'd be lucky enough to end up with her. She is 5ft 10ins tall, and has the most wonderful long thin legs imaginable, and a slim upper body with medium sized tits. I later found out that she has really thick nipples. Her hair was blond but she said it was bleached by the sun and that she was actually a redhead. After I knew her better I said there's only one way to find out for sure, and she cheekily replied that I'd have to wait because she'd just shaved. She told me that she had a lot of male friends and not to worry about them, they are not a threat. She knew how I'd split with my ex-girlfriend and said that she just wanted to be treated right and I wouldn't lose her if I did. The first night that I took her home I couldn't believe how lovely her body was - I must have kissed the whole length of her legs, and when I got to the top, I noticed the gap between both legs was quite wide but her twat was tiny, like that of a teenager, even though she was 39. I licked her out for ages which was giving me a really good hard-on, until I couldn't stop myself from mounting her, she was so wet, but amazingly tight. I couldn't believe my luck, and now I always lick her out before we have sex. We both love it. After the first few months (when I was completely hooked on her) she started getting more texts messages from male frinds than before, and started going out for a drink much more often than before. I suspected that one or more of them must be shagging her but when I challenged her we would argue because she denied it, so I hoped i'd catch her out one day, but wanted to do it in such a way that I could let her know I still wanted her because I loved her body so much. One man in particular (Stan)who was 57 years old e-mailed me some naked pictures of her, and when I told her about them she just said they were done a few years ago when she got divorced because it lifted her self esteem, and that Stan was just an old friend. i had no proof so I had no option than let her go out with him for a drink once a week. She denied there was anything sexual until one day I found a video tape with her and a bloke called Nigel, and Stan was filming them. There wasn't penetrative sex, but she sucked both their cocks. Stan was about the same size as me (8 inches) but the other guy was 9 or 10 inches, and really thick. I didn't tell her at first because I was so turned on I wanted to watch it again. One eveening when she went out I went through all her unmarked video tapes and found another one where Stan was filming her with a different man called Clive. He was about 6ft 2ins tall and was in his late 50s. He was a giant of a man in every way. She was lying next to him on the bed slowly stroking his cock, and it must have been 11 or 12 inches long, I gasped at the size of it, at one point she had one hand around the base of it, the other hand around his thick tool half way up, and there was still enough of his massive cock on view which she was then sucking. I must have watched the tape dozens of times wishing I was there licking her out while she was doing it. Eventually I told her about the tapes and obviously I did it in the wrong way because she went mad, we argued and we split-up. We were apart for about 3 weeks until I texted her saying that I wanted to talk to her and have her back. I was so jealous of the huge cocks she was getting and I was going without. I spent every single day thinking about the lucky men that were enjoying her and I couldn't wait to get her lovely taste back on my tongue. We met one morning and I held her tight and kissed her repeatedly and told her how I missed her, and would give anything to taste her again. We went back to her place and spent about 4 hours in bed. She stills goes out with men friends but I don't think she trusts me enough to tell me about what she gets up to. She says they are just firends, but I know there is no way these men would be satisfied being just friends. I can only guess they all have really huge cocks, and I have to think of ways to catch her at it, so that she can see me enjoying watching her, and hopefully joining in. It's my guess that she likes to keep me guessing about whether or not she's getting it elsewhere, and she enjoys thinking that she got away with it each time she gets fucked by another man, but I'm dying for the opportunity to let her know that I would love to be with her next time so I could see her enjoying it. There are other men I suspect but I'll write about them separately . . . . . .
