I work for a company that fits security systems, I am the surveyor.  I visit the houses of potential customers, and give them a quote.  I was called to a big house, electric gates, big plot.  All it lacked was a swimming pool.  There was already a good system fitted, but they wanted it replaced by a more modern one. 

It was a summer Saturday morning.  Not unusual, quite often customers were at work during the week.  I pressed the button on the gatepost and the gates swung open.  I was expected.  Waiting for me at the front door was a woman in her forties, but at first I thought that she was much younger.  She was wearing very revealing tight shorts and a blouse, unbuttoned but tied at the waist, displaying her ample, bra-less tits.  She was barefoot.  I said;

 "Mrs Wentworth?"

"Yes," she replied, holding out a hand to be shaken.  "Natasha.  People call me Tash."

Her handshake was firm, causing her exposed tits to wobble.  I felt that familiar stirring.

She showed me around, explaining what changes and additions were required for the new system.  Inside, the house was as impressive as outside, the master bedroom was huge, with the biggest bed that I had ever seen, but there was still space for bedroom furniture including armchairs in two of the corners.  On the wall facing the bed was a large TV.

Tash's perfume was subtle but intoxicating, but there was something else, the scent of arousal.  I was very familiar with it.  She stayed closer than was strictly necessary.  I had more than a semi, more like a three-quarters.  It had not gone un-noticed.

My survey was complete.  I said that the quote would arrive next week.  She asked me if I would like tea.  I had only the one survey that day and I was in no hurry.  I said yes.  As she bustled around the kitchen, I asked;

"Where's Mr Wentworth?"

"At work,"she answered.  "He's always at work."

"Do you work?"

"I used to.  I was a model, I've also done bit of acting.  But Steve doesn't like me to work.  Besides, looking after this place is work enough."

I could fully understand the model part.  She hesitated and then added"

"He can be a bit of a bastard at times, he fucks other women."

At first I said nothing.  I also fuck other women, so I was not about to take sides.  That was why I was in no hurry to go home, I was currently in the doghouse for doing just that.  In my job, opportunities present themselves and I'm not one to turn down an opportunity.  My wife Shelly knew that I was no angel, nor was she. But I had no idea what had got her so pissed off about my latest excursion.  She had been sleeping in the spare room for more than a week.

I considered my reply carefully, then said;

"You could get your own back by fucking other men."

"Would you fuck me?"

"I certainly would."

"Will you fuck me now?"

In under a minute, my trousers were around my ankles and she was on her knees with my cock in her mouth.  As she feasted on my cock, my hands feasted on her tits, her blouse was undone allowing me unfettered access.  As much as was enjoying her oral skills, my ten day celibacy was causing me problems.  Reluctantly I pulled her off.  She stood and kissed me on the mouth, then said;

"I need fucking.  Upstairs."

She led me back to the master bedroom, saying;

"I want you to fuck me in his bed."

She pulled the duvet right off and removed what little she was wearing.  By the time I was naked  she was spread on the bed, rubbing her clit.  I pushed her fingers aside and replaced them with my mouth.  She was dripping, ripe mature woman juice.  I tried to drink it all.  She came, squealing with pleasure.  Then as her spasms subsided, said;

"Fuck me now, I need your cock."

I had condoms in my wallet, I went to fetch one.

"No," she moaned, "Just fuck me, give it too me, every drop. He hasn't fucked me for ages."

She fed my cock into her cunt with both hands, then enfolded me with her arms and legs.  I would have liked to make it last, but did not have the will power, spunk was screaming for release.  Her cunt felt as good around my cock as had her mouth.  I accelerated my strokes.

"What the fuck is going on?"

Boomed a deep voice behind me.  Her husband's voice.  Where the fuck had he come from?  I rolled off, my cock now shrivelled.  There was nowhere to hide, nothing to cover myself with.  We were both stark naked.

"Steve!"  Cried Tash.  "It's not what you think!"

What else could it be?  I was in his house, in his bed, in his wife.  It was exactly what said on the tin.  I went to collect my clothes.

"Stay exactly where you are!"

He boomed.  He was a big man, older than me but very fit looking.  Handsome bugger really.  I stayed exactly where I was, trying to cover my driving force with my hands.  Tash was still on the bed, also trying to cover her bits with her hands and arms in that way that women have, arms covering her nipples, hands covering her cunt.  Steve fished out his 'phone and said;

"What's the number of your employer, I can tell you for certain that you're fired."

He turned to Tash and added;

"And you can pack your bags."

"No, please."

She pleaded.

"I'll make it up to you," she turned to me.  "Won't we?"

What could I do to make it up.  I fumbled for words, then said lamely;

"I'll make sure that you get a good discount on the new system."

He roared with derisive laughter.

"A discount?  Do think that would make it alright for you fucking my wife.  How would you like to find another man with his cock up your wife's cunt?"

He had a point.

"That's exactly what it will take.  You will deliver your wife to me to be fucked.  Bareback, in all holes.  You can both watch me do it.  Bring her here by eight on Saturday, dressed for a good fucking, or it's you who are fucked."

I slunk home, very much with my tail between my legs.  The chances of Shelly agreeing were somewhat less than nil.  I was going to lose my job and it was at a time when jobs were in short supply.  If I lost my job we would not be able to pay the mortgage, I would lose my house.  And almost certainly, my wife.  And I had not even finished my fuck, the spunk destined fo Tash's accomodating cunt was congealling in my aching balls.

Shelly exploded when I told her, and walked out.  I sat alone on our sofa, head in hands.  I was finished.  Shelly returned after a couple of hours.  Her first and only words were;

"I'll do it."

I was saved!  I texted Steve to tell him.  Shelly came to my bed that night, but pushed my hand away when I  tried to touch her.

"Not a chance," she said.  "You've pimped me out to a stranger.  The only reason you're here is so that I can keep my eye on you.  If you try to wank, the deal's off."

There are of course, other places to wank than in bed, but I had no inclination to.  I was walking dead.

When the time came, Shelly really did dress to be fucked, even though I had not mentioned Steve's words.  I was made to watch.

"Watch me prepare myself to be fucked by another man."

She said.  She was enjoying my discomfort.  I delivered her as ordered, on the dot of eight p.m.  at first it was as though we had been invited to dinner, we were offered aperitifs.  Eventually, Steve said to Shelly;

"So you're here to settle the debts for your cheating scumbag husband?  Has he explained the conditions?  You are to suck my cock until I tell you to stop.  I will then lick your cunt until you come.  Then I will fuck your arse.  Then I will fuck your cunt and fill it with my spunk, I will not use condoms.  Finally, my cheating bitch of a wife will suck my spunk from your cunt."

Despite my remorse, I had a towering erection.  Shelly nodded.  We went upstairs to the bedroom  where he had caught me with my cock deep inside his wife's cunt.  He carefully undressed my wife, kissing each uncovered part, lingering on her tits.  Shelly had worn stockings and suspenders, she was told to leave them on.

Shelly then undressed him, went down on her knees and I watched breathlessly as she sucked his extremely large cock into her mouth.  Steve looked across to where Tash and I stood and snarled;

"You, Cuckold and you, Whore, get your kit off."

We silently obeyed.  Steve pulled Shelly off his cock and told her to get on the bed.  True to his word, he then licked her cunt until she orgasmed noisily.  She quickly repositioned herself on all fours, ready to receive his monster in her arse.  He applied copious amounts of lubricant to her tight pucker and to his cock.  He was going to need it, when she is in the mood, Shelly likes it in the arse, but the thing that was being prepared for entry was huge.

I could not believe how hard I was, in this situation I should have been angry, horrified.  Instead I was fascinated.  I held my breath as inch by inch, his massive cock disappeared up the arse of the woman I loved.  I wanted to move closer, but was frozen to the spot.  Steve withdrew slightly, then pushed back in.  Shelly was muttering incoherently. Steve reached under to hold her tits and began to fuck her, slowly at first, then faster and faster until he was ramming her hard and fast.

It was impossible to tell, but I was sure that Shelly had a second orgasm. Just from being buggered!  She never had when I had done it, at least not without assistance from my fingers or hers, on her clit.  I looked across at Tash, her fingers were busy doing naughty things with her own clit.  I was desperate to wank, but it seemed wrong.  I was not supposed be be enjoying this, it was supposed to be my punishment.

Steve suddenly stopped, he must have been very close to losing his load.  He slowly withdrew,  his thick shaft and bulbous knob gleaming with the abundance of lube.  Shelly fell forwards onto the bed, turned over and spread her legs for the finale.  She reached down to feed Steve into her cunt, a look very close to bliss on her face as he filled her.  Just as Tash's arms and legs had done with me on this same bed, she wrapped herself around Steve. The dark welt of her stockings against her pale skin and the tightly stretched suspenders, made it look like the finest porn

Unlike when he had fucked her arse, he fucked her cunt with slow, deep thrusts, as though prolonging the act.  Whether for my discomfort or his pleasure was not yet clear, but it became clear from the look on Shelly's face that it was for hers.  I knew that look, I like to look at her face as her orgasm builds, she was rapidly approaching another orgasm, her third!

I watched as the look changed to one of ecstasy as her climax racked her near naked body. Steve pumped faster, then thrust erratically as his own orgasm took him.  I knew very well what was happening, when Shelly comes, her cunt goes into a sort of milking mode, gripping, almost wanking whatever is inside her at the time.  Steve snorted and rammed himself deep inside, Shelly's clasping cunt did the rest.  I saw his arse-cheeks clench as he emptied his spunk into my wife.

He took a few seconds to catch his breath.  Shelly's face now wore a satisfied smile.  He rolled away, Shelly remained in her spread position, legs wide, cunt gaping wide from being pounded by Steve's supersized cock, creamy white spunk oozing out to trickle down between the cheeks of her arse.

"Clean her up Whore."

He growled.  Tash almost sprang to obey.  She licked Shelly's spunky hole from anus to clit, then clamped her mouth over it.  Exactly as I do when I suck cunt, she pushed both arms under Shelly's thighs and round to hold and squeeze Shelly's tits, thumbing the erect nipples.  Shelly's expression changed again to one of pleasure.

Tash was arse up, lapping at my wife's cunt.  Her own cunt gaped wet and inviting.  My cock was at bursting point.  If only.  Steve's voice broke my reverie;

"Fuck her if you want, she likes it from behind.  Finish what you started the other day."

I looked at him in disbelief, he nodded, smiling.  I was confused, I was being punished for doing what he was now inviting me to do?  My cock was saying 'Yes!', my brain was expecting a broken nose if I did.  Cock won.  Tentatively, I lodged my straining tip between the inviting wet lips and slid easily in.  I looked across at Steve, still half expecting the punch, he was still smiling.

I turned back and my eyes locked with Shelly's.  She too, was smiling.  Actually it was more of a grin.  Suddenly everybody was happy.  True, Shelly had just been vigorously fucked by a huge cock and was now enjoying the ministrations of Tash's tongue, but was I missing something here?

My cock was happy too, if it was not deep inside Tash's warm cunt, I suspect that it too, would have had a smile on it's little face.  It sent a telepathic message to me;

"Don't think, fuck."

And I did.  I was too pumped up for it to be anything other than a relief fuck, so I just went for it, all the time looking into my wife's eyes as I pumped hard into another woman's cunt.  A woman whose mouth was clamped to my wife's just fucked cunt.  Shelly was now mauling her own tits, Tash's hands were streching Shelly's cunt wide for access.  As I drove into Tash, the grin on Shelly's face melted into a grimace as she reached yet another orgasm.  I lost it and lacquered the inside of Tash's cunt with high pressure cum.

All was still for a few seconds.  I pulled my still hard cock out of Tash, sat back on my heels and relished the sight of the backwash from her plundered fuck hole.  She sat up and walked on her knees, straddling Shelly's still jerking body, until her dripping cunt was directly over Shelly's mouth.  I could not believe what I was witnessing, silver strands of my cum dripping into my wife's mouth.

Then Tash lowered herself, queening Shelly.  I watched goggle-eyed as Tash's orgasm shuddered through her body.  Tash then rolled sideways  revealing Shelly's face, wet with the cum and cunt cocktail that Tash had fed her.

They both started to giggle.  Steve sat on the bed next to them, also grinning from ear to ear.  Shelly said;

"You've just been had."

Bewildered, I looked from face to face.  Shelly said;

"Meet my boss Steve.  You already know his wife."

They had cooked all of this up together, as punishment for my philandering.

"From now on," said Shelly.  "If you fuck another woman, I want to know all the juicy details, especially the part about using a condom.  I want reciprocal rights, I will fuck anybody that I fancy, you will get to hear about it."

It was taking a long time for me to absorb all this.  Eventually I looked at Steve and said;

"So you've been fucking my wife all along?"

"No," he said.  "That was the first time.  But I hope not the last."

I looked at Shelly and said;

"And the lezzie thing?"

"Also a first," she said.  "For me anyway.  And I hope, not the last.  Thanks Tash, I fucking loved it."

Steve placed himself between the two girls, an arm around each.

"Choice of two," he said.  "Who would you like to fuck next?"

I expected Shelly's cunt to be slack after being reamed out by Steve's titanic todger, but was pleasantly surprised as her sheath wrapped my cock in a familiar embrace.  Aren't women wonderful?  I enjoyed the even tighter grip as she came.  How many was that?  Five?  Aren't women wonderful? 

I kissed her as I fired my second helping deep inside shortly afterwards, reclaiming her as mine, displacing Steve's contribution.  Assuming that Tash had left any.  Alongside us on the bed, Steve was reclaiming Tash in the same way, fucking her lovingly from behind.

Even though I had been given the green light, I never fucked another client.  My needs are well catered for by Shelly.  We now fuck even more than we did when we were first married.  Most days.  Sometimes two or three times a day.  At the weekends, we frequently meet up with Tash and Steve for foursomes, where we each fuck both our respective partners and each other's.  Any flagging interest is soon cured by the sight of the girls going at like there was no tomorrow.

But I just wish that they wouldn't slurp all the cum from each others cunt, I just love sloppy seconds.  They get the best of the arrangement, they each have three fuck buddies.  Steve and I just two.  So far we have not attempted double penetration of either Tash or Shelly, something to look forward to.  Nor have we been tempted to try man to man sex, although I have tasted his cum from one or other of the cunts.  One day perhaps.  I think I'm ready.

I was taught a lesson.  A lesson worth learning.
