My gf/wife sharing journey

Hi all.. I joined this site over a year ago but other than a few private message exchanges with 2 or 3 individuals, I've remained largely anonymous, instead choosing to visit the site every few days when horny to read what folk have been up to and to watch some media uploads..

I'm now at the stage where I feel comfortable sharing my particular gf/wife sharing journey (which includes some bi fun) from the very start back in 1999 through to current day.. I promise that eveything I write is 100% factual and not just a fantasy..

A bit of background about me, I'm a white male in my mid 40's living in Central Scotland..

In the mid 1990's, I started seeing this girl (lets cal her Mel) shortly before her 18th birthday.. I had had a few sexual partners by then but whilst she had experienced orgasms through self pleasure, she was still a virgin.. She quickly became hooked on sex and was starting to enjoy things such as oral and in particular anal.. She found it difficult to orgasm through standard penetration unless her clit was being stroked or her asshole was being played with..

We purchased a couple of vibrators and a butt plug.. When masturbating alone she would often use the dildo in her ass, and when we had sex, she would want me to use the butt plug on her as I fucked her pussy.. This then developed into me using the dildo instead as the girth was giving her more pleasure..

When I was using my fingers on her ass to get her warmed up, she would somtimes reach back and we'd both finger her ass at the same time.. And if she was really horny, I would ask her to do it to herself as I stood over her and held her ass cheeks apart so I could watch up close.. She'd sometime manage 4 fingers ploughing deep into her asshole.. It was unbelievably sexy..

So here I was, a 20yo fucking my 18yo girlfriend in the pussy or ass, with a dildo in whatever hole I happened to not be inside at the time.. At such a young age, she was already experiencing the feeling of 2 cocks and she loved it.. However at this stage, the thought of another guy joing us hadn't even entered my mind.. I don't think she had considered it either as she never brought it up.. Or if she had, she certainly didn't mention it to me..

Fast forward a couple of years (she's now early 20's) and she gets a new job in a music store selling CD's.. It's quite a young crowd she works with including her manager (lets call him Tom) who was mid 20's.. She was a friendly girl who got on with everyone but one day, she came home to say something odd happened.. She said she was in the back storage room when her manager came in.. The door was kept closed so nothing unusual about that but he was standing in a narrow walkway meaning when she walked past they both had to shuffle past each other sideways so she couldn't help but brush up aganst him.. As she went past, he put his hand up to stop her then just stared at her a few inches from her face.. He didn't touch her or anything like that but she did get the feeling he wanted to try something on but was maybe scared how she'd react..

When she came home and told me, I was fine with it as nothing happened.. But I then found myself thinking about it when I was wanking alone.. A week or so later, we were fucking missionary style and I was looking right into her eyes and blurted out "I bet Tom would love to be doing this to you right now".. Her reaction was a bit shocked at first but I kept going with "have you thought about what could have happened" and she admitted yes as we both came hard..

This was the first time we had mentioned to each other the thought of another guy being part of our sex life..

I'll leave it here for now.. There is lots more to write about assuming folk want to hear about it so let me know if thats the case and I'll come back with more..

If there is a more appropriate section to post this on, please let me know and I will move it..
