So after the events of the Xmas party and the next day everyone was back at work on the Monday. The atmosphere was subdued, one of my managerial colleagues R was trying to find out what happened as it was obvious to her something had as nobody was mentioning anything. A little about the company I don't want to say too much so people I have mentioned cannot be identified but it manly involves dealing with the public usually by phone latterly by computer but has a reception area for walk ins. The managers such as myself are brokers and there are four of us ,then we have staff who help with the main work ,the secretarial and admin staff with cleaning and support as well. We have a large UK head office that provides IT managerial support etc and generates custom nationally.

So Dirty M who I will just call M is doing admin and reception work but she has other qualifications and is trying to get other better paid work as a therapist which suited her training. She was married to a big bloke called S but was now going through a bitter divorce.

She said nothing and avoided me all week and I didn't have the opportunity to approach her but on Friday she lingered briefly at the copier as I approached and passed me a piece of paper saying, have a look at this, everyone in the office was looking at us.

I went to my office closed the door and opened the scrap of paper. It was a website address for a swingers website for threesomes and a user name. I was excited but couldn't use the works computer so when I went home turned on mine and went to the website. I had to register then typed in the user name and there were pictures of M! There were a dozen or so none showing her face mainly in a black basque or other lingerie with heels and stockings then the last three pictures were her with her legs open showing her pussy with the lips folded away then a pink dildo inserted into her and finally a naked man with a huge cock.

She had also put her phone number on the paper and as my wife was not home I texted her.

Can you talk.

She immediately called back.

Did you enjoy last weekend she said

Of course I did what about you?

Loved it I love being naughty but you have a lover.

Who is the guy with the big cock?

That's who I am seeing ,he is a therapist as well and is trying to get me a job, he is also called S.

To cut a long story short her husband S caught her having an affair with a man who owned a hotel also called S so he left her, then when she told Hotel S they could be together he said he wouldn't leave his wife so she dumped him then started to fuck Big Cock S and as all men were wankers decided to have some fun and go to clubs and start a swinging lifestyle, she had fancied me from joining the company and her Husband S thought she was fucking me but until the party an opportunity had not arisen. Now we had each other's phone numbers we could talk away from the prying eyes of the office she told me all about her swinging, how they started soft swinging at first then how she enjoyed the power of deciding who could fuck her at a club and who couldn't it was a kind of revenge on men but she loved getting fucked and making men come as the power was in her hands or between her lips and legs so to speak.

She also said she had never come at a club or even a couples swap but I didn't believe her. We got on well and she was becoming a good friend one Sunday in the new year I was feeling randy and texted her.

Are you busy? Do you fancy a coffee.

Ok but meeting a friend for lunch you will have to be quick.

I jumped in the car and drove thirty minutes to near where she lived ,she left her car in a supermarket car park jumped into mine and drove off. Hers was a Mercedes convertible she had from her marriage as Husband S was well off and I drove a roomy Mercedes E Saloon.

She looked gorgeous, she wore a slinky figure hugging grey woollen dress which had a plunging surplice neck line and slit at the front showing one leg, black stockings and heels but had straightened her curly hair she looked a different woman.

I drove down a lovers lane we got in the back pushed the seats forward and started to kiss,her soft sensual lips were all over mine and we were locked in a passionate embrace, my right hand quickly found its way into her knickers and rubbed along her wet slit which once again was dripping cunt juice. I broke off,

Have you fucked Big Cock S this morning

No but would you mind if I had

No of course not it turns me on

You make me wet now finish what you started

I pulled off her knickers the started to flick her clit, her breathing shortened then she came noisily on my hand. When she came down she said now your turn but you have to be quick as I am meeting a girlfriend for lunch, doggy is usually quickest.

She told me to get out of the car and then turned to face away from me knees on the seat

Go on then fuck me

I lifted her dress and drank in the perfect view her black hold ups the milky white soft flesh of her upper thighs above, then her lovely bum and her pussy lips hanging down open and gaping , reddened from where I had been rubbing them. I pulled out my cock and put the purple head between her lips and eased in, then grabbing her hips started to fuck her, long slow strokes at first, she was grunting with each deep stroke then as I started to speed up I could hear something and stopped.

What is it she said

It a horse and rider what should we do

Stay where you are and smile

So a horse came into view with a middle aged woman riding it on the opposite side of the car she looked at me and I waved she didn't smile just stared ahead and slowly rode by. When she had gone I said to M I think we got away with it the windows are blacked out so she couldn't see you.

Really so what is a bloke doing standing by the back door of his car down a lane with the door open unless he is fucking someone of course she knew,are you going to finish as I have a lunch date.

I thought it would have stopped me coming but I was still hard and started to pound her I love looking at a women's lips as they grab your cock when you pound her and started to feel my orgasm build, then spurted into to her juicy cunt three or four times.

As we adjusted our dress she said it always seems eventful with you now thank you for the orgasm but take me back to the car.

A few days later R came into my office, she was ten years older than me, she had grey blonde tinted hair a tweed skirt, glasses and a blousy chiffon top with lot of frills she was very cross.

Are you having sex with M I have heard rumours and you know the company policy about staff and relationships you are leaving us open to a lawsuit.

I stood, smiled gave her the glinting eyes and stood behind her kissing her neck, I then moved in front lifted her blouse then lifted her big tits or bosoms as she would prefer to call them out of her bra and started to kiss her nipples and breasts whist rubbing her pussy through her skirt.

Stoppit G but then the giveaway moans and the way she grabbed the back of my head and pushed herself onto me told a different story.

She is one of only two women I have met who could orgasm through nipple play and she did, I should say that I had not fucked her at that point but we had done this once before after she had confided she had not had sex for ten years and I had offered to help.

Her face and chest were flushed after her orgasm and I said don't worry it is in hand.

R said ok but what would your lover think so be careful then left the room.

I know it sounds like everyone is at it, but it is all true and you can bet this is going on where you work as well,women like sex and men don't have an off switch so it is hardly a surprise.

Nothing happened with M for about six weeks then one day I said goodbye to my lover whom I had had wonderful sex with all afternoon and mine phone buzzed it was M with a text.

Can I come to yours after work, she knew my wife was away,luckily I had popped a viagra earlier that day.

Of course I replied

My only thought was should I wash my lovers pussy juice off my dick
