By the start of the 1980s Penny and I had our first child and were eager to get back into the party scene. We contacted some of our old friends and pretty soon found a regular group that met once a month for a 'No Holes Bared' group sex session.  Our first attendance was a sort of 'get to know you' event and Penny and I had one partner each only that night. We didn't mind, that was fine, but Penny (always a show off) was busting to try a night of multiplayer sex. To be honest so was I.
We eventually got the chance over a  bank holiday weekend when our hosts had planned an all night party. I must tell you now that Penny was never one for dressing up. She didn't do the school uniform, corset, thigh boots thing at all. Her only concession was a small suspender belt and coloured stockings, and if she was into a serious fuck they got chucked as well. She loved to be naked.
The party got really going at about ten and there was all sorts going on . The hosts had a large house and the main room was furnished with fold out bed settees. These had been deployed and a lot of sex was going on. Penny was naturally totally naked and this seemed to attract attention for some reason. I was busy trying not to cum too early down a big girl's throat and Penny had two men spit roasting her. She told me later that the man fucking her had called a chap over to look at her 'beautiful little arse' so there was now three of them all using my Penny. They flipped her over on her back and the first one got his cock in her and started banging her. She had another in her mouth and the third sucking her tits. It didn't take long for her to give in to her first orgasm. As I have said before, she does tend to make a bit of a fuss, and tonight was no exception. She let out her usual high pitched squeal and torrent of dirty talk and bounced and shook and trembled until it had finished. The bloke who was actually fucking her was so surprised he looked down at her and said 'bloody hell girl, do you do that every time?' to which Penny just giggled and said 'yes if you have the energy'. With that he renewed his efforts and dumped a load inside her. As he withdrew and Penny ejected as much of his cum as she could the second chap took his position and pushed his larger than average cock up my wife's creamy pussy.
One of the things that really turns Penny on is to see me push my cock into another pussy. She loves it and sometimes likes to hold my cock and guide it in for me.
My girl was still sucking slowly at my cock and I asked her if she would like me to fuck her. She immediately said yes and I took her to the sofa next to Penny and her three friends. I laid down on my back and told my girl to slide herself down on my cock. This would give Penny a perfect view of my cock going deep into her cunt. Penny knew it was coming and wrapped her legs over the chaps back and got her legs as wide as possible. My girl held my cock up straight and slid her wet pussy down my length.
Penny exploded. She cried out and convulsed hanging on to her lover like a Boa Constrictor squeezing the sex out of him. He too didn't last long after that, and while Penny still hung onto the last of her orgasm, he dumped a huge load into her.
So, I am laying close to my little, skinny, totally naked wife, with her pert little tits and a pussy full of cum and I couldn't hold it any longer. With a huge grunt I unloaded. The girl fucking me was quick and got off my cock just in time and most of my load went up her back or over her arse. She collapsed on top of me with her tits on my chest and her arse in the air. I found out later that it was her husband who got in behind her and fucked her hard while she stuck her tits in my face and I sucked hard on her nipples till she too climaxed with a gasp.
After this we all kind of settled down a bit while we recovered. I helped Penny clean herself up and the big girl had her head in her husband's lap sucking his soft cock clean. I asked Pen if she had fun and she said she had and fancied another go to see if she could get three off in one night. I don't remember where the other guys went but we stayed with Big girl and her husband and Pen asked if she could suck his cock. Big girl agreed on one condition, that Pen let him fuck her and she would cum again. Penny was fine with all that and set about sucking this guy's cock back up to vertical. She hurried things along a bit by telling him that she was pretty desperate to get his cock up her. As soon as he was hard she put her leg across him and sat down on his cock. She supported herself with her hands on his chest and worked her hips back and forth and at the same time he played with her tits. Big girl and me got in a 69 position and I buried my face in her ample thighs while she devoured my cock. Penny was working well on her guys dick and he had hold of her little arse and was pounding her up and down on his cock. She was moaning and talking dirty to him urging him to fill her up.
I pushed big girl over onto her back and she pulled her knees up to her chest and said "Quickly, fuck me now, I want to cum". I lined up my cock and pushed it into her. I heard Penny crying out "Oh my fucking god" and she orgasmed with a scream and her usual rigid trembling and shaking as she  banged her self down on his cock. He had a hold of her waist and was lifting her up and down. There was a ring of creamy foam round the bottom of his cock and it was very clear that Pen had really enjoyed that one. She urged him on with more dirty talk and he couldn't take any more and as Penny giggled and wriggled he dumped a load inside her. I couldn't wait for Big girl and I quickly pulled out my cock and shot my load over her face and tits.
Big girl was now desperate to cum so I stuck two fingers then three up her pussy and pounded away at her G Spot. At the same time her husband detached himself from Penny and put his creamy cock next to his wife's face. She devoured his cock like a Sunday roast with a pensioners discount and cleaned him up with relish. My fingers were working hard and she pushed herself down on them and let out a long moan as she climaxed with her husband's cock still in her mouth. We all collapsed back on to the bed, and I wrapped Penny up in my arms and kissed her deeply. After a moment or two I went and picked up two beers and a half drunk bottle of wine for the girls. Me and the husband chatted for a while and the girls shared the bottle between them. Big girl was sharing stories with Pen and they both agreed that a gang bang must be a fabulous feeling. Penny confessed that three loads up her was the most she had done so far and Big girl said that she wasn't on the pill or anything so she wouldn't be able to experience that. By this time three lots of cum were starting to drip out of Penny's cunt and Big girl was keen to see how much there was. Me and the husband found it hilarious that there was Penny squatting over Big girls hand so she could see how much cum Pen could push out. She was really surprised and told her husband that she would really like to try it and she thought she would go back on the pill again.
I found a cover and a couple of cushions and pulled the cover over me and Pen and we snuggled up and soon went to sleep. We woke up early, and quietly found our clothes and got dressed. There were some other people moving about but we didn't stay and made our way home for some breakfast and then back to bed.
