Simon slowly withdrew his long thin cock from Lynn's arsehole, his still hard shaft glistening in the low light, wet with lubricant and his own spunk, the rest of which was still deep inside Lynn's arse.  

Lynn is my wife.  Was I jealous?  How could I be?  My own cock was balls deep inside the tight arsehole of Simon's wife, Jenny.

Lynn was supporting herself on her knees and one elbow, the fingers of her other arm busy between her legs, guaranteeing her own orgasm.  She remained in that submissive, head down, arse up position, anus gaping from Simon's intrusion.  After a few seconds, a trickle, then a sticky blob of cum oozed out, slowly ran along her moist cuntlips, to hang suspended until the increasing weight caused it to break away and fall onto the bedsheet.

That did it for me, with a grunt, I fired my pent up load into Jenny.  I savoured each spurt, let my cock soak for a few seconds, then I too, slowly withdrew and sat back on my heels to enjoy the spectacle of the spunky backwash from Jenny's hole.  Unlike Lynn, Jenny was on her back, holding her ankles to spread herself for me.  In erotic slow motion, my gift escaped to be soaked up by the sheet.

The sight was enough for me to remain fully erect, but the thought of what was to follow would have done that anyway, the finest experience possible, sloppy seconds.  Anal sloppy seconds.  The girls remained in position as Simon and I shuffled to change places.  I delayed my own re-entry long enough to watch as Simon's impressive organ disappeared entirely inside the hole that I had stretched and lubricated.  Where does it all go? Simon's tool is well over an inch longer than mine, mine is six and a half inches, his must be nearly eight.  But what I lack in length  I make up for in girth.  A sort of quid pro quo of cock.

Lynn wiggled her arse impatiently, keen for her second helping of anal.  I'm not one to keep a lady waiting, I lodged my tip at the slimy entrance and fed my length slowly in.  Lynn groaned as it stretched her.

This would be the finale, I am no superman.  I can occasionally come more than once in a day, three on a good day, but rapid fire like this required preparation.  These foursomes happened about once a month but the build-up, the abstinence, part of the foreplay, had started the day before.

I said that I was not jealous of watching another man sodomise my wife, I am not.  What I am jealous of is Lynn's capacity to orgasm repeatedly.  In my teens I could wank several times a day, six or seven times at weekends.  But not any more, after this I would need rest, lots of it.

Both myself and Simon had learned to pace ourselves, but not limit ourselves.  We had both fucked both women.  Dry fucked.  We had our cocks sucked by both, but not to completion.  In return, both women had been sucked, fingered and fucked by both men, giving them numerous orgasms.  Another inequality was that the girls had also sucked and finger-fucked each other.  They both had previous lesbian experience, they both seem to enjoy the taste of cunt as much as I do.

They have tried hard to persuade Simon and me to go man to man.  We have not.  Yet.  I suppose that it's inevitable, certainly I am curious to discover what it's like to suck a cock, to experience the sudden burst of spunk flooding my mouth.  And although Lynn has arse-fucked me with a dildo, she assures me that it's no substitute for the real thing.  Yes, it will happen, it's a case of when, not if.

Our foursomes had, up to now, followed the same pattern.  Starting with dinner, alternately in each other's homes,  the food being washed down with plenty of good wine.  Then we would adjourn to the lounge.  There would be much snogging, groping, undressing, fondling and sucking, culminating in the first penetration, sometimes with our own partner, sometimes each other's. 

But I digress, I had a job to finish.  I had maintained a steady rhythm, reaming my wife's arse, using her fine tits as handles.  She was still supporting herself one one arm,  still busy strumming her clit, giving herself a series of mini-gasms which I was enjoying as her cunt clasped my cock.

My cock was in Lynn's cunt, but my eyes were on Jenny, she too was pleasuring herself.  Simon was kneeling, his hands holding Jenny's ankles as he pumped her.  Her hands were busy at her cunt, fingers of one buried inside, fingers of the other rubbing her clit.  Her ample tits, slightly flattened by gravity, wobbled on her chest in time to Simon's thrusts.  I could feel my cum coming, I increased speed, racing to the finish, emptying my last dregs into Lynn.

I was done, spent.  They called for a taxi to take them home, then cleaned up, dressed, said goodnight and let themselves out.  Lynn was soon asleep beside me.  Despite my exhaustion, I was unable to sleep.  I lay on my back, hands behind my head.  My mind went back to the early years of our marriage, it had been very different back then.  I had expected a life of domestic bliss, a steady if boring job, perhaps kids.  Certainly swinging had not been foreseen.  So how did it all start?

………….

One year ago.

It had been raining for most of the day, typical for a summer Saturday.  I had caught up on neglected jobs while Lynn, my wife went food shopping.  I showered while she prepared the evening meal.  Saturdays like this usually ended with us eating in, something a bit special, always with a bottle of good wine.  Foreplay for what was in store for later.

Now it was later.  Lynn was already in bed when I entered the bedroom after locking up.  Duvet up to her chest but with one lovely tit 'accidentally' peeping out.  I did a striptease for her, by the time I was naked, the peeping tit had been joined by it's partner, both nipples were erect.

So was my cock.  I slipped into bed beside her, as we kissed, her hand found my erection.

"Have you got something for me?"

She asked.  We both find 'talking dirty' a massive turn on, this was the prelude.

"I certainly have."

I replied.

"Oh good, what is it?"

She asked, in her little girl voice.  I placed my lips close to her ear and said softly;

"Spunk."

I felt her shudder slightly.

"Spu-nk," she repeated, drawing the word out, savouring the word as much as she savours the substance.  "How much spu-nk?"

"At least a cockful."

"At least?"  She asked.

"It regenerates, but that's your job.  Where would you like it?"

"What are my options? "

"I could shower your tits with it, or you could have it in your mouth to swallow, or in your lovely cunt, or if your really good, I could fill your arse with it."

I could feel her shudder again.  For us, anal had been a recent development.  She had a bad experience years ago, but if you like, she can tell you about that in another story.  Now the idea of anal both thrills and scares her.

"I want it in all those places."

She said.

"I don't think I've got enough for that," I teased.  "That would take more than one cockful."

"From more than one cock?"

She asked innocently.

"That could be arranged."

Suddenly the mood changed, from playful to serious.

"You wouldn't."

She said.

"I would, if that's what you would like."

There was a pause, then;

"Would you really allow other men to fuck me?"

"I would pay good money to watch, provided I could reclaim you after they had all had you."

"Do you have anybody in mind?"

"Take your pick, every man we know would like to fuck you."

Needless to say, this led to one of our most spectacular sessions, during which she received not one cockful, but three.  I excelled myself.  And yes, the last one was fired right up her arse.  It turned out to be a really wet Saturday. 

We lay panting, recovering from our exertions.  She said;

"Were you serious?"

"Were you?"

"I asked first, do you really want to watch me fucked by others?"

"Isn't it every man's fantasy?"

"You tell me, I'm not a man"

"I would love to watch other men fuck you.  Dont tell me that you've never fantasised about fucked and buggered simultaneously, the meat in the sandwich, or being gang-banged."

She didn't reply, which I took as a yes.  I could almost see her thinking about it.  Eventually, she said;

"And you would fuck me when they had finished with me?"

"The best part, sloppy seconds, a well buttered crumpet."

I dont remember falling asleep.

And so it all began…
