I was asked how I started swinging,  that question sent me back a couple of years. It started when I saw a woman, Sara, I had been bedding in my local pub. I said hi, and a man walked up behind me and asked me to join them. Sara looked worried,  the man asked me to help him with drinks and told me he was buying.  As we waited for the drinks he introduced himself,  Jim. He asked if I was fucking Sara.  I told him I was.  He nodded and asked if I wanted a mfm. I  thought about it, looked over at her and said yes. Condoms he asked. Not so far I told him. Excellent he said. We took drinks back to the table,  Sara looked uncomfortable. We drank our drinks, I don't remember what we talked about. Then Jim asked who's we were going to. Sara offered her place. We walked. Sara paused, key in her hand. I told her we both want you and asked if she wanted us both to come in. She opened the door.  I shut it behind us. Jim kissed her and held a tit. Do you want us both, I asked. She nodded.  I opened her top. Jim took a tit in his mouth. I  kissed her dropped her skirt and felt her pussy through her nickers.  We took her to the bedroom. She took her nickers off. Jim told her she was a good girl. We stripped and lay each side of her. Kissing, sucking tit and finger fucking her.  I asked her who was first.  She did not answer. I looked around, took something off her bedside. Put my hands behind my back and told Jim "empty hand gets first go". He picked the empty hand. He pushed his hairy cock into her hairy cunt. She held my cock, tugging on it. She moaned gently as she always did, as she did she tighten her grip on my cock. Jim came. I kissed her, she kissed back open mouthed and hungry. I fingered her as she kissed. It was the first time I felt another man's cum in a woman.  She let me up as she moaned again.  Clean his cock i told her. She knelt over him, sucked his cock and I slipped into her doggy. Lubricated by Jim's cum. I looked at her head bouncing on his cook and felt sloppy cunt, my balls slapping wet. I kept up gentle thrusts till I came. I knew it was a big cum. I knew it was big because I was sharing her. I managed a few more thursts. She came I stood by the bed. She turned around and started to suck my cock. Jim told her she was a good girl and started to pound her. That was my first spitroast, both ends. He came in her. Told her she was a good girl again. We lay her between us, kissing her, finger fucking her then eating her. Her hair was matted with strings of milky spunk. Jim went to the loo. I asked her if she was OK. If she enjoyed two men. She nodded, I kissed her, I knew she was excited by everything,  I lay on her and took her again. Her kisses were almost violent, her hands clinging to my back. We came, perfectly timed, together.  I rolled off her  Jim was watching from the door. Have you had her ass yet he asked. I told him no. Jim rubbed her ass with leaking cum and lifted her legs. I saw his cock slide into her ass. Jim pounded her fast and hard. He came, she did not. Your turn he told me, I've stretch her for you. I kissed her, she responded,  happy that she was happy I fucked her ass doggy. She was tight and my first ass. I enjoyed her, firing cum into her. Jim said we should wash our cocks. Do you like ass he asked me. I told him I did and he asked if I ever had a man. I  said no, guessed where it was going. He never pushed the point. All he said was if you want to try he liked cock. When we got back to bed she was laid there, wet tissues beside the bed. Jim told her she was a good girl.  We both fucked her again,  played and fell asleep. I woke. She was looking at me. Jim's hand on her tit. I kissed her, ran my hand down her body. She winced as I found her matted Bush. She turned on to her back. Opened her legs. Bit her lip as she pulled her bush apart. Jim woke as I fucked her. I rolled off after leaving my morning load. Jim took my place, Sara moaned and Jim came in her. Sara went to the bathroom and returned with no bush. Jim told her she was a good girl,  but this time the word were laced with surprise and astonishment.  We spent the day fucking watching porn that Jim found and fucking some more.  That's the way it went on for the next few months. Sometimes we fucked as a 3some, sometimes she took only one of us to bed and I had a couple of one night stands, once I fucked Jim but never wanted to do it again.  A few months later Sara phoned me, asked me to make a 4sum with her gf who was staying with her while she found a flat. Jim would be the other man. I walked to the pub, found Sara, Jenny and Jim at a table.  Chat was about the weather but soon moved on to Jenny's new job, which Sara helped her get. By the time we moved on to the Italian the conversation had moved on to the flat she was looking for, then flims. We finished the shared a bottle of wine and Sara suggested we find something on Netflix. By the time we started the walk to her place Jim and Jenny were getting on well. We got back to the flat. Sara kissed me, the next time a saw Jenny she was snogging Jim. Sara told them they could use the bedroom. Jim took her by the hand and shut the door.  Sara opened my shirt and I dropped her skirt. "No nickers, you slut" "You like that!" Her top came off, she dropped my trousers and sat on the sofa sucking my cock. I let her then knelt, kissed her, tipped her back and started to eat her shaved pussy. There was a loud exhortation from the bedroom. I raised my head, tipped her back, kneeling on the floor, I pushed my cock into Sara. Sara told me, "I hope your going to do as good a job, Jim got Jenny off" I did, but she only moaned softly as she always did. I sat up by her and she asked "You want her?" "I do, do you want to see?" "I do" she got up "we better do it then,  while she is excited " We opened the door, Jim was on his back, Jenny sucking his cock. Sara sat on the bed by Jim asked "Can I borrow him Jen?" I sat on the bed and placed my hand on Jenny. She stopped sucking, looked at all of us in turn.  Jim said,"be a good girl let him have you." Sara played with Jim's cock and told Jenny "Jake is good, as good as Jim" I moved towards Jenny, she kissed me. It was not lustful. She looked at Jim feeling Sara's tit. Jenny kissed me again, gradually becoming more passionate.  I heard Jim tell her she was a good girl.  Jim and I ate each other's cum, me from Jenny's tightly trimmed pussy. She yelled as she came.  I climbed on her, slipped into her. Jim pushed his cock into Sara saying "good girl" we fucked them side by side. I heard Sara moan, came myself kept fucking heard Jenny yell and felt her nails bit into my back.  Sara reached over squeezed Jenny's hand, "I  told you he was good"  Jenny asked "You have done this before?" "The three of us, yes. You did enjoy it,  I could tell. We all enjoyed it." "We can do it again,  now" We swapped again and took them both doggy. The rest of the weekend was spent watching Jim's porn, fucking, copying some of the positions. We had Indian sent in Saturday.  I lost count of how many times we fucked. We fucked who and when we pleased. I think everyone made the first advance.  We watched each other,  we fucked side by side.  That went on for nearly a year, sometimes all 4 of us, sometimes 3sum or 2sum..  I'm not sure who suggested going to a club but we went one Friday night. After booking in we changed, took the 3 condoms from the lockers and went into the bar. We opted for a wrapped round towel,  Sara covering her breasts Jenny just covering her lower half.  I few single men eyed them up. One even said hi. We chatted to him but we were waiting for a couple. Andy and Jan arrived,  we introduced ourselves.  The girls gave us the nod and we suggested a private room. The couple took us to a room. There was a glass wall but no one could enter the room. We told them we were a 4sum and suggested the two girls look after Andy and we look after Jan. No one said they had boundaries, but it was to be safe sex. We played around a bit,  I forgot about the glass wall and only occasionally looked across at Andy and the girls. Jan lay down and opened her legs. Jim started by eating her pussy. I attended her top half. I looked over at Andy, on his back Jenny sat on his cock and Sara sat on his face. Jim came, I pulled a condom on and took my place fucking Jan doggy. Jenny came loudly as she always did. Jim started pounding Jenny as Sara sat on Jim's cock. I looked around at the fornication and I remembered the glass wall. I let my cum go into the condom and sat back. Jan turned snogging me like bitch on heat. She broke away and reached her hand out for Jenny who was now full of Jim's cum. Jenny took her hand, "he filled you" Jan said. Jan bent and started to lick at the leaking cum. Jim told Jenny she was a good girl. Sara came and looked at the other two women.  She put an arm around me and I pushed her on her back.  I fucked her hard and fast. I was not sure why, the discovery of Jenny's bi side or claiming Jenny back from this stranger or then crowd on the other side  of the glass wall. She was high on the clubbing fucking this stranger and being seen. This time she did not cum softly moaning. She let out long loud morning 'fffuckkk' We did not part, we held each other I'm not sure how long. When we parted Jan held Jenny in an embrace watching Jim and Andy sucking cock 69. I watched both embraces. One more pleasing than the other. Jenny encouraged Sara to join them.  I was not sure, but Jim started sucking my cock. I gave into the moment and started sucking both cocks. Jim and I refilled Jenny and Sara, Andy ate and fucked them. He fucked his wife bb and everyone ate her. We all rested then went back to the bar after a shower. We picked a second couple and went to another room. That was almost as exciting. No bi action. We went to the club another 5 times, sometimes selecting couples, sometimes men, once a woman. We went to a club a few times. Then I moved away with a new job. I visited a couple of times. The last time Sara was married,  I was the first man she had since she was married. After I left Sara, Jenny and Jim I went to clubs, joined the site, shagged men and women and finally ended up on the island.
