We had been into swinging for a while. Rosin was still shy and would only swap behind closed doors and not even in the same room as my and whatever partner I had. The last swing had brought us and invitation to a party. We attended and again Rosin managed to sneak off to a room and lock themselves in so they could fuck in private. I was much bolder and had fucked the hosts wife in front of several other couples. Not that they were interested as the were also fucking. Afterwards I wandered to the bar area and had a drink. A young looking woman I had spotted earlier came for a drink and got more than she had bargained for as I fucked her leaning on the bar table. Eventually Rosin emerged from the room looking as if she had just been talking. There were no signs or traces that she had just been fucking. I was still naked and went in search of my clothes and then we went home. Over the coming months we attended several more parties and Rosin still managed to slip away with just one partner in private. It also dawned on me that the worst bit was getting started at these parties. I decided that we needed a game to get things going. Rosin and I had often played Libido a sex board game on our own and in private. I designed my own game with chances and forfeits. I had the facilities at work to print stuff and to produce board. So one Saturday I stayed behind when everyone else was going home and printed the cards and made the board. I nicked the money and some of the parts from an old monopoly game and parts fro a few other games. It was ready. Rosin and I had talked about hosting a party and at the next one we attended we handed out invitations. Between those at the party and some other swinger friends we had ten couples who said they would come. Once they had all arrived I told everyone that we were going to play a game. I hadn't told Rosin about the game. Everyone sat down on the floor and I handed out the instructions. There were few rules so everyone was soon ready to play. We started with pairing. I was a quick game where you got paired with a partner. It wasn't necessarily the partner you would end up with. Also there was a chance that instead of couples we could end up with some threesomes. I cheated and made sure Rosin was in a threesome. She didn't seem phased by it. Howard the luck bastard also got a threesome. The game started and most chose chance when they fell on the chance squares. There was lots of touching and kissing. Brandy took it to another level when she had to touch someone in a private place she had Ron take his own cock out and her touch was when she sucked it into her mouth. Then Rosin fell on a square where she had to choose and went for chance. She got a swap card. She could swap one or both of her partners for some one else. She held on to the card instead of using it straight away. Most people had lost clothing and Rosin was down to bra and panties. Several couples had peeled off and found other rooms. I had been lucky and pulled a partner swap card. I too had meld onto it. Greg had one and swapped his partner. On the next round Rosin ended up with a hand in her panties. I was surprised that she had let it happen in front of everyone that was left. Then Josh pulled the last swap card. He used it to swap, Brenda, his partner for Rosin. Rosin used her straight away to swap back. She had now locked herself into having two partners and not just Josh. It surprised me, but that is what it is. One of the men with Rosin pulled a go to bed card and he and Rosin and the other man got up and left the room. Then the game fell apart and those that were left were making out. I took Raven, my partner, to see if I could find us a place that was a bit more comfortable. All the bedrooms were occupied and When I entered tour second lounge Rosin was on her back on the sofa with one of her men fucking her throat and the other one licking her pussy. I settled into a chair with Raven and was kissing and stroking each other. We were soon removing our remaining clothes. Then as I sat on the chair Raven straddled my lap and lowered herself onto my cock. The chap licking Rosin's pussy was now removing her panties. Rosin looked a little panicked as he climbed between her legs. She looked straight at me as if asking for help. But she never said anything. Then the chap penetrated her and Rosin groaned with the cock still in her mouth. Then it was like a switch had been thrown. Rosin was humping back at the cock and she was grunting and groaning. The chap in her mouth came in her mouth. As he withdrew his cock some cum run down her chin. She gulped the cum in her mouth, took a big breath and sucked the softening cock back in her mouth. My ride was close to coming as was I. Both of us were watching Rosin as she humped at the man fucking her. She was like a wild animal as she humped and grunted and groaned. Then she groaned louder, as the cock fell from her mouth. I guess she had just come. The chap continued to fuck her for a few more minutes before he was grunting as he unloaded into her pussy. It was the first time that I had seen Rosin with another man. I came deep in Raven's pussy and she slumped forward as she also came. To my surprise the man whose cock had just fell from Rosin's mouth was quickly between her legs sucking at her pussy. Rosin's hands were on his head and she was trying to control the mans action on her pussy. She was again groaning and almost purring between moans. Raven remained on my lap even when my cock slipped out. We watched Rosin receiving a good licking. Rosin's other man was now trying to put his limp dick in Rosin's mouth. She greedily sucked it in. I almost felt jealous, but pride and excitement were stronger feelings as I watched Rosin dealing not only two men but also doing it in front of others. We had been joined by another couple. Then Rosemary pulled Raven off of me and went about sucking my cock back to full strength. Her partner swapped with the chap with his cock in Rosin's mouth. He was already semi hard and face fucked Rosin. The displaced chap joined Raven on the floor and they were in a sixty nine position. Rosin was taking some serious face fucking. I had never fucked any woman's face like that and it looked like Rosin was enjoying every inch of his cock. Then it was all change as the man liking Rosin's pussy had her turn over onto all fours and he fucked her long and hard from behind. The other chap was still face fucking Rosin and she was being shuttled between the two cocks like a bobbin on a weaving loom. The guy fucking Rosin came groaning out his pleasure. He was quickly replaced by her face fucker. I was amazed that Rosin had now sucked and fucked three cocks and in front of others. It was about now that I came and pumped my stuff into Rosemary's pussy. We cuddled the best we could on the chair watching Rosin getting a good hammering from behind. The guy fucking Rosin pumped another load of cum in her pussy. and he moved away. Rosin stayed in the same position with her arse in the air and said, "Who's next?" She didn't have to wait long before Greg and his partner joined us. He went straight to Rosin and as his cock was soft he offered it to her mouth as he fingered what must have been a very sloppy pussy. At this point having recently come twice I needed the loo and went off upstairs. I found Gail sat on the toilet seat sucking another dude and had to ask them to move before I pissed myself. Gail held it for me as I peed. I found another couple on the stairs fucking as I went back down stairs. She sucked my cock for a few minutes before I moved on and went for a drink. Back in the lounge Greg had moved on and another chap was fucking my wife. He lasted a long time before he came in Rosin's pussy. People were beginning to leave and not necessarily with their life partners. I got grabbed by a delightful young lady and dragged to a bedroom. I spent the rest of the night with her. In the morning I went to look for Rosin and found her in another bedroom. She was in bed with one of her two original partners. She awoke with a huge smile on her face. After we had got rid of all the rest of our visitors and finished clearing up, we sat exhausted cuddled up on the sofa. I asked he had she enjoyed herself. All she asked was, when could we have another party. I joked about her fucking five of the men who attended. Rosin corrected me and told me that she had fucked six of the ten men that had attended. She wouldn't let me play with her pussy saying it was sore. I wasn't too surprised having six different cocks in her in one night. After that night Rosin became an exhibitionist and would fuck anyone she fancied and pulled a number of trains in the four years we were in the lifestyle. Then as we wanted a family we stopped. Now as our children are older we were talking about starting swinging again, but then the virus struck, so I guess we will have to wait until life gets back to some form of normality.
