This is an erotic story based on a real experience I had together with some imagination.


“How would you like to fuck Karen”. I looked at Mike open-mouthed. He and Karen were old friends. I’d watched them as their relationship developed, seen how they couldn’t keep their hands off each other. I’d helped them move her things into his place. That was more than 2 years ago and now here he was sitting with me in the pub, both of us a little drunk, and asking me if I’d like to fuck her. Truth be told, I would love to fuck her. She is an attractive girl, good figure, long legs. She’s also very sassy and self-confident, with a bit of a naughty touch to her. But she’s Mike’s long-term girlfriend and there is no way that I could invade his territory. “We’ve talked about it” he said, “and decided that we’d like to try a threesome”. That concerned me. Those ideas so often have unintended consequences. “Come on, Mike” I said, “That’s the drink talking”. “No really” he replied, “we want to experience it and we know you, so it’s an ideal arrangement”. The idea was now growing on me. The thought of fucking Karen, of feeling her long legs wrapped around me, was making me hard. But I knew that this would be a step into the unknown. “Look, why don’t you come round for drinks tomorrow night and we can talk about it together” he said. “Alright” I replied, “but no promises”. That night I lay in bed and stroked myself as I thought some more about fucking Karen .....
The next evening I went round with a bottle of Merlot. Mike was quite hyped and opened it straight away. Karen was looking lovely as ever, dressed in jeans and a t-shirt. We soon sank the bottle, talking about all manner of things until Karen turned to me and said “well, Alan, what do you think of our idea”? I was cautious because I really didn’t want to mess with two good friends. I said that I very much liked the idea, but that I was worried it would cause problems. I was worried about causing jealousy and anger. I didn’t want to lose them as friends and I didn’t want to fuck up their relationship. Mike tried to reassure me. He told me that they had a very strong bond, that they both wanted this, and that Karen wanted to try a different man. He wanted to watch and perhaps be involved. I asked Karen if this was truly what she wanted. “Oh yes” she said “that’s exactly what I want, and you are perfect for it. You are a friend who we know well and you wouldn’t hurt us”. Well by now I had a raging erection and was starting to leak precum. But it was important to set some rules. “Ok” I said “but we need to agree how this will work. First, I decide what happens. If we do this, it’s my way. I won’t do anything that’s not wanted, but whatever I do will be my way. Second, Mike you will not be asked to agree anything. If you want me to fuck Karen and she wants me to do so, you will have no further say. Do you guys agree”? There was no hesitation, they both said yes.
I was by now really excited. They were sitting together on the sofa so I went to join them, sitting on the other side of Karen. I took her hand and placed it on my cheek. Then I leaned forward and kissed her. I kissed her deeply. I explored her mouth. I sucked her tongue. I licked her lips, sucked them. Then I kissed her neck, sucked her ear. I held her close to me, rubbing my chest on her bosom. I felt her breasts through her t-shirt (she wasn’t wearing a bra). I felt her nipples hard and erect. I ignored Mike. Acted as though he wasn’t even there. She had her hands under my shirt feeling my back, then my chest and rubbing my nipples. I lifted her t-shirt and felt her breasts. They were full and firm with erect nipples. Hell this was one sexy girl. Soon we had our tops off and were feeling each other. I kissed her breasts, sucked her nipples. By this stage we had both heated up and were squirming around. She stood up and dropped her jeans and panties and next minute I was looking at her bush - a luscious mass of curly black hair surrounding a beautiful pink pussy. It was just waiting to be to be licked, sucked, tickled, and tongued and that’s just what I did. I sucked her lips and ran my tongue up and down her slit. I licked her clit gently, feeling it engorge and get larger. I stuck my tongue into her pussy and tried to lick the inside top. By now I was unstoppable. I took off my jeans and placed her hand on my cock. She held it at first, then started stroking it, running her fingers over it. She rubbed my cockhead with her index finger, spreading the precum that had formed. She fondled my balls gently. I carried on worshipping her cunt. Then she said “I want you inside me”. This was the big moment. I looked round to see if Mike was there. He was - he’d been watching, his face flushed. I asked him if he was ok with it. I said that if he was, I was going to fuck her now and things would never be the same. He said he was. Once he’d said that, the dynamic changed. I was now firmly in charge and he was just an onlooker. Karen was now my woman. Her cunt was mine. What he said and did was now irrelevant. So I turned back to her and said that we were going to the bedroom. I took her by the hand and led her there. She lay down on the bed and I started to kiss her again. Then I sucked her neck hard, leaving a mark. Then I did the same on her breast - she was my woman and she would have my marks on her. When Mike looked at her, he would see my marks and know that I had been there. They would be living reminders. Then I licked her all over. I licked her neck, her shoulders, her arms, I licked her breasts then sucked her nipples. I trailed my tongue down past her navel and sucked in her public hair. I licked down the inside of her groin and left another mark there. Then I concentrated on her cunt. She was rubbing her clit and saying “fuck me, Alan, fuck me”. She pushed her hips up towards my mouth, I put my hands underneath her bum then slid my fingers round to feel her cunt while I licked her clit. She was murmuring my name and moaning. I couldn’t hold off any longer. My cock was pouring precum so I rubbed it up and down her slit. “Go slowly” she said, “you’re quite big”. I told her not to worry, I would go slowly, giving her time to adjust. She reached down to hold my cock and slowly pushed it into her. I felt that special moment when the head pops past the opening and starts spreading open the vaginal walls. Oh the feeling was stupendous. Here I was inside another man’s woman, stretching her. She was mine. I was going to do things with her that would make our toes curl, and all he could do was watch and wish. I was going to make her so satisfied that she would always come back to me for more. I looked down and watched my cock slowly move deeper into her. Her lips were tight around my shaft and I watched them being dragged inwards. I could feel my cock go deep inside, spreading her wide until my head brushed her cervix. She groaned and hooked her legs around mine, thrusting up her pelvis. Mike came closer and put his hand on her bosom, but she pushed it away. He was the last person either of us wanted. I now began fucking her gently, long, slow strokes. I wanted to lift her somewhere she’d never been before, to feel things she’d never felt before. Every now and then I’d stop with my cock embedded to the hilt. Then start again. I could feel her clit brush the base of my shaft on the deep in stroke. I could feel her muscles gripping me, her vagina rippling up and down my cock. I watched my shaft drag her lips outwards and then inwards. I watched our pubic hair entangle and get wet with our secretions. I felt every part of her vagina, every fold. My cock felt warm, comfortable and wet inside, and then cool as I pulled out before slowly moving inside again. Then slowly her rhythm started to change. She held her breath for longer, she pushed harder. She put her hands on my backside and pulled me towards her then pushed me away. I speeded up to match her thrusts when suddenly she cried out and held me tight, her body shaking. I had never been with a woman who’d orgasmed like that, and it pushed me over the edge. I thrust hard into her and held still, spurting semen deep inside her. My mind went blank and all of my thoughts were in my cock. It was the most intense orgasm I’ve had. I must have ejaculated 10 times. My semen oozed out around the base of my cock even though it as so tightly gripped by her lips. Then slowly I relaxed along with her and just lay motionless on top. Mike started to say something, but I told him to shut up and fuck off. Then I withdrew from Karen and cuddled up to her. My semen flowed out of her and wet the bed. I rubbed her cunt feeling the slippery substance and used it to rub my fingers around her clit. Of course we talked as lovers do, close intimate secrets. She hadn’t experienced an orgasm like that before either and had been amazed at the intensity. We carried on kissing and cuddling and touching and I started to get hard again, which allowed me to enter her spooning on our sides from the back. That was a long slow gentle fuck seeming to go on for ever. It was not as wild as the first time, but was extremely sensual and romantic. She came again, and cried out when I came too. She told me she loved me. After that we got up and went back to the lounge where Mike was sitting. Karen went to him and gave him a big kiss and thanked him for bringing me into their relationship and that it would not affect what they had. He seemed a little stunned by it though, but said that he was pleased and had found it very exciting to watch. I had not been aware of him at all, other than when I told him to fuck off. He hadn’t left then and had watched us cum which he said had been extremely arousing but at the same time had made him feel jealous and superfluous. Karen told him not to be so silly and that nothing had changed, he was her man. He’d left after the first time so did not see the tenderness of our second fuck. I spent the night there on the sofa and left in the morning. I felt incredibly empowered. I’d had a spectacular time. I’d fucked another man’s woman and made her mine, made her forget him entirely while she enjoyed my cock. I’d made her forget her fidelity and been in her cunt which had previously belonged only to another man. I’d helped her orgasm in a way she had never experienced before. I’d filled her with my semen and perhaps impregnated her. I was sure she would be available for me any time I wished, regardless of Mike or what he thought. All of that was hugely powerful.
It did change relationships. Mike retreated into himself and lost confidence. I felt bad about that but I had warned him. Our friendship continued but in a strained fashion. Karen wanted me to fuck her again, but without Mike being there, which I did on several occasions. Whether Mike knew or not I had no idea. It wasn’t the same as the first time, but still extremely enjoyable. It had the added turn-on that I had displaced Mike and that she preferred me sexually. I also loved cumming inside her and imagining her going back to him with my semen seeping out of her cunt. I pictured her sitting with him, her panties wet with my semen, his girlfriend but my fucktoy. They stayed together for a few more years but gradually drifted apart until they separated. As for me, I got such a kick out of it that I actively sought out other couples wanting the same. There are plenty of them around ......
