This story is based on events that took place some years ago when Katie was in her early twenties.
Katie and her partner, John, who she lived with, shared an apartment near London. He was a fun guy, and they had a good relationship, doing a lot together, going out, travelling and a common interest in music. They also had a robust sex life! Katie, quite petite at 5ft 3in tall, has always looked rather good, in fact very good! Back then she kept her blond hair relatively short, just down to her collar, always cut well. Katie was, (and still is), slim, with a great pair of legs, firm smooth thighs and a very well-shaped bottom. However, her boobs have always been her most significant asset, just perfect, at a 34D size, but firm so she hardly needed a bra.
John was a slim, wiry guy, about 5' 8", with a head of untidy black hair. He seemed always to have a smile on his face, perhaps because he laughed and joked often. At the time, when Katie and John had few cares, they were perfect together, enjoying life, sucking in everything around them, making the most of whatever fell before them.
John had a friend named Colin, whom he had known for some years. Katie knew him well enough as he used to visit them regularly, often staying for the weekend. In terms of physique, he was the opposite of Katie and John, much taller at over 6', well built, the sort of guy who seemed to be able to lift extraordinarily heavy objects with ease!
One evening, Katie and John had been out to eat or for a drink, returning to the apartment afterwards. John was sat on the sofa with Katie alongside him as they shared a bottle of wine. They were talking idly, about nothing in particular, when John told Katie that Colin thought she looked terrific, sexy and with a great figure. Katie was quite flattered.
"That's nice to know," Katie said, "I think he is a lovely guy, not bad looking too!"
"Well, that's good," replied John. "You know, I must confess that I've always had a bit of a fantasy about you flirting with Colin."
Katie turned a little to look at John, a smile on her face. "Really?" she asked, "You would like that? How long have you had this fantasy?"
"Oh, I'm not sure, a while I suppose. I know it's silly."
"No, it's not, if it's something you like, then it isn't silly. I could maybe be a flirt if you like that, wear something rather sexy one evening. Tease Colin a little bit," said Katie.
Rather shyly, John said, "I thought it might be fun if you were very sexy, naughty, even very naughty perhaps. That you might like being sexy and bad, it might be a turn on for you as well."
"Oh, well, gosh, there's an idea," Katie replied. "I'm not sure what you have in mind. I could do something, and maybe I could strip one evening. I could strip right off, how about that? What were you thinking?"
John, bashfully, then told her that he had sometimes thought about her making love to Colin while he watched. Katie was surprised but quite intrigued and asked him why he would like this to happen, what turned him on about it. Relieved that she hadn't got cross he explained it was just a fantasy, he was fascinated with the idea of seeing what she looked like during sex, what she would look like, moaning and moving while Colin had sex with her.
Katie thought for a moment about this fantasy of his. "Well, sometimes it's possible to make a fantasy come true, but we'd have to see how it might work out." Katie told him, "The right time and all that."
"Wow, really, you'd do it with Colin?" John asked, obviously surprised.
"Maybe. Colin's a nice guy and pretty good looking too, which rather helps, and I think you would like me to do it!" Katie replied. "But we do, of course, have to see if Colin is interested in this idea."
"Just out of interest, if you did it with him, would you go all the way?"
"How do you mean, all the way?"
"You know, would you let him come inside you?"
"Why do you ask?"
He was embarrassed again now. Perhaps he felt he was pushing the whole thing too far or that Katie would become angry; however, John explained why he had asked.
"I'm just not sure, I know it sounds absurd, but I'm just not sure about him coming in you, it's such an intimate thing," John replied. "It would be very sexy to see your face, to watch you arching your back while Colin is coming inside you, but then I feel strange about him doing that, spunking in you, maybe it's too much."
"Hmm, well, we will see! You said this is something you've fantasised about for a while and it's quite an erotic idea, so yes, I'll do it with Colin, and you can watch," Katie told him. "However, let me work out how to make it happen. I can't very well say to Colin, hey give me a shag and do you mind if John watches while we do it, can I now."
During the next week, Katie thought about what they had talked about and started to formulate a plan, a plan that would take a few weeks to complete. Katie wanted to do this to please John, but it was also because, the more she considered it, the more turned on she became at the thought of doing it with Colin while John watched. Katie liked pushing the boundaries sometimes, to explore further in their sex life.
Plan Part 1.
Sometime, maybe a month later, Colin came to stay for the weekend as he lived some miles away. On Saturday evening they stayed at home, had a meal, a few drinks and then sat talking and listening to CDs. At about 10 pm, Katie said that she wanted to get comfortable and was going to change, ready for bed so that she could relax.
Katie had, of course, planned this. She went upstairs and put on one of John's white shirts, a pair of white knickers and a pair of fluffy white socks. Katie deliberately left half of the buttons on the shirt undone, so while not exposing her boobs, you could immediately tell she wasn't wearing a bra. When she went back downstairs, John and Colin both sat up, clearly surprised at how she looked. With a big grin, Colin said she looked very sexy, which of course was true! It was summer, and she had an overall light tan, which looked fantastic against the white clothes.
Katie didn't do anything at first, just sat and had another drink, but after a while, she stood up, pulled John up and told him to smooch with her to the music that was playing. He did, but before too long he had pulled the shirt up and had his hands inside stroking her back. Katie shivered slightly as John did this but with the shirt pulled that way it wasn't comfortable. She moved away from him slightly, undid all of the buttons on the shirt so that he could put his hands inside, around her waist and on her back. It was altogether more comfortable and looked a lot sexier to Colin who was, of course, watching them.
When the track they had been smooching too finished Katie let go of John and said to Colin it was his turn. He didn't need to be asked twice, standing up immediately and pulling Katie close to him so that he could smooch with her along to the music. As John had done, he too put his hands inside her shirt, on her back, caressing her as they moved. Now, let's take this a little further thought Katie.
