Tis is my first story on her and a true one. Names have been changed just in case anyone knows us. I'm Josh, 27, 5ft 8' slim and about 6.5uc. My girlfriend Lisa is 28, slim about 5ft 6, 34 DD, and trimmed tight pussy. She's had 2 other boyfriends (that she's said about that is). She's told me a couple of stories bout being with them like being pumped out on the veranda on holiday. And with ther first boyfriend how when having sex the condom broke and he shot in her. I kind of a like the thought of watching her getting used by another lad and during sex will maybe tell Lisa a story about a couple of my mates shagging her. I will even say their names too and this is normally enough to make her cum although after she doesn't mention it. So that's the background so far. Now here's what happend. Last week I was out with my mate John at the football. John's 28, about 5ft 11' normal build and no bad looking. We went for a drink in town after the football and started talking about our respective birds. Johns girlfriend is 4 moths pregnant. He was saying that she's off sex the now but is normally really up for it. He said "I canny wait till she gets to the horny stage and wants pumped cos I'm fucking choking for fanny". John is one of the mates I have mentioned during sex with Lisa btw. After another one we started talking bout Lisa with me spilling some of the beans about what we do in bed like she loved to feel me shoot a load in her and also about what she had done with her ex. I could help but notice that John was sporting a hardon in his joggys. He was saying shat Lisa was fit and said "fucking hell Josh I canny believe you telling her stories about me riding her ya dirty wee fuck". Time was getting on and we ended up heading up to mine so as he could sober up a bit before going home. I will admit that I couldn't get the thought out of my heade about having a 3 sum. When we got in Lisa was watching the telly and sitting in quite tight fitting pyjamas. She made the two of us a coffee and as she did I went into the kitchen and told her that I spoke to John about our stories. She got a bit red in the face, and said "you fucking better not have". I laughed but noticed both her nipples got hard. I then went to the toilet and when I came in they were talking about me and what I had said. John asked if we wanted a game of truth or dare and was surprised when I said yes. Even more surprised that Lisa said yes. I told him it better no end up with Lisa hinging off the end of him to which she gave me a slap on the arm. Lisa was first and she went for truth. John asked if she had ever had a 3 sum. She said no. I asked if she liked John to which she said aye but no in that we...... Niple even more hard. John next he went for dare. I dared him to kiss Lisa. She kinda held back but he did and it wasn't short. My cock went rock hard. So did his. He kept kissing and I started feeling Lisa's tits. Before you know it we were all undressed, well we had our boxers still on but down. Lisa was on the couch sucking me off whilst John was licking and playing with her clit. I should have already mentioned that John was a dirty fuck. He was telling her how he's no had a shag in weeks and is chocking. He sat up and moved his cock up to her pussy. I couldn't belive it he was putting it in with nothing on. He was about 7 UC and thick. She took him all moaning. He was ridding her for ages when he pushed me back a bit so Lisa wasn't sucking me and started to kiss her and pump hard. As he said he was about to cum at the same time me and Lisa said "take it out". But too late he made a mess in her. As he got off his cum started running out of her tight cunt. I manovered over her and thought fuck it. I slid in. She felt different and really wet. It was a bit weirded feeling his cum on my cock too. I was done and made her cum again within a couple of minutes. That was the first of many times Lisa let John use her during his birds pregnancy. She thought that she was gong him a service and helping keep them together. But that's another story.........
