I admit it, it was entirely my fault.  I was looking at my phone and went arse-over-tit not knowing that if he penetrated this most private hole, she would come instantly, the pavement.  The phone was a write-off and I had a bloody nose for my sins, fortunately not broken.  But the owner of the wheeled suitcase which had been my downfall, was very apologetic.  It was a while until I was able to see through my tears, we recognised each other at the same instant.

I had known Kev since school, we had been best mates for years.  My wife Liz had been his girlfriend until she turned her affections to me.  I suppose that's why we lost touch.  But ten years on, he had hardly changed.

"We need to catch up,"  I said.  "Shall we get a coffee or something?"

"I'd love to mate," he replied.  "But I've just arrived in the country, I need to find a hotel."

"Hotel bollocks," I said.  "You're staying with us."

He had been coming out of Paddington station, having arrived from Heathrow on the shuttle, I was going in to the station to catch my train home, very close to Heathrow.

Was I asking for trouble, inviting him into my home, where I lived with his ex?  Not really, even in my blooded state, I had realised that he might just be the man we were looking for.  After ten years of marriage, Liz and I were looking to spice things up a bit and after much discussion, had agreed that she would fuck another man with me watching.

Ideally, he would fuck her bareback so that I could experience sloppy seconds.  That was the stumbling block, (Not counting his suitcase!) where could we find a suitable man who could be guaranteed to be 'clean'?  Of course, Kev might not be, but if he said that he was, I could trust him to be telling the truth.  I also knew that he would be acceptable to Liz, until I stole her, they were fucking on a regular basis.

All this went through my mind in a matter of seconds, that's why I had invited him to be our guest.

Liz was already home, to say that she was surprised was an understatement, but she was not exactly overjoyed.  Nevertheless, she cooked the three of us a meal while I made up the spare room bed and Kev showered and shaved.  Neither of them had a clue what I was planning.

Over dinner, we caught up.  Kev had just returned from the middle-east, having terminated a two-year contract after only six months.  After dinner, Liz left us to talk while she cleared away.  What had caused Kev to quit early, it had to have been a lucrative contract?  He made sure that Liz was not within earshot and said;

"Blue balls mate, no women."

I couldnt think of a country, even in the middle-east, that had no women.  I said as much.

"Oh there are women," he said.  " But they would castrate you for even thinking about it.  I was paranoid that I  was being bugged to make sure that I didn't even wank.  Yes, the money was good, but there are things more important than that."

"So how long as it been since…"

"Six months," he said.  When you fell over me, I was deciding whether to find a hotel or a massage parlour."

Perfect, just perfect.  All I had to do was persuade Liz.

At first, in bed, when I raised the subject, she refused point- blank, but she eventually agreed that it made sense, she could hardly say that she didn't fancy him, they had parted on good terms.  If he had been telling the truth, he was almost guaranteed to be 'clean'.  He would have the satisfaction of getting his own back on me for stealing his girlfriend, I would have my sloppies.

The next day was a Saturday.  Kev said that he should go flat-hunting.  Cunt- hunting more like, I thought.  I managed to persuade him to put it off until Monday.  Over dinner later, we would make him an offer that he was unlikely to refuse.

Although she has just turned forty, Liz is still a very desirable woman.  She is petite, elfin.  Accentuated by her Liza-Minelli-in-Cabaret hairstyle.  She has always thought that her tits were too big, disproportionate to her frame.  I have always said that tits can never be too big.  Admittedly, age and gravity have taken their toll, and they are no longer self-supporting, but to my mind, and hands, that's not a bad thing.  She wore a short dress, concealing her best, sexiest undies.  Kev was about to get the best dessert of his life.  This time, I cleared up after dinner, leaving them sat together on the sofa.  Liz's dress had ridden up, revealing her stocking tops.  But the time I had rejoined them, her suspenders were also on display and the bulge in Kev's trousers was very obvious.  I nodded to Liz, she turned to Kev and said;

"I want you to fuck me, I've missed you."

Kev spilled his drink and looked guiltily at me.

"Fine by me," I said.  "As long as I get to watch."

His jaw dropped.  He turned back to face Liz and suddenly she was all over him, kissing him passionately.  Kissing him?  Until that moment, I had been sporting the mother and father of all erections, as their lips met, my cock seemed to pull it's head back like a terrified tortoise.  I had not envisaged kissing.  I had imagined her wanking him, sucking him, feeding his rigid cock into her cunt.  I had imagined him sucking her nipples,  licking her cunt.  But kissing had never crossed my mind, kissing was, well, intimate.

But that ship had sailed.  Already he had her tits out, scooped out of her low-cut dress.  Liz straddled him, grinding herself on his erection.  She pulled at his shirt buttons, kissing him again.  I cleared my throat noisily and said;

"Can we move this to the bedroom?"

They looked like teenagers caught in the act.  Sheepishly,  they disentangled and we trooped upstairs.  On the landing, Liz hesitated and said to me;

"Our bed?"

I really had not thought this through.  I nodded.  In the room, they finished undressing each other, Kev's impressive cock at last revealed.  I dont remember it being that big.  I was the forgotten spectator, I stripped off and pulled the bedroom chair closer to the bed.  My erection was back.

Liz went straight for his cock, sucking it deep.  Steady girl, I thought, don't waste it.  I was pretty sure that Kev had releived the pressure in his balls last night, I certainly would have done if Liz hadn't done it for me.  Even so, six months without a female hand around it, let alone lips, would have me firing like a machine gun.

Kev pulled her off and rolled her onto her back, she spread herself for him, almost doing the splits.  She was of course, still wearing the stockings, the suspenders stretched tight along her widespread thighs, framing her lovely cunt.  From my vantage point, I could see how wet her cuntlips were, parting in anticipation.

Kev leaned over and kissed her again and again I felt a pang of jealousy, but this time, nothing less than an earthquake would have lessened my erection.  I had my fist around it, but was afraid to wank, I would have lost it.  Kev moved his attention to Liz's tits, kissing them, sucking the erect nipples.  Then he moved south.  Liz whimpered and spread herself even more, pushing her hips up from the bed, anxious for his tongue.

As his lips touched hers, her body jerked and she made a little mewing sound.  Her hands went to his head, his pushed beneath her thighs, raising her knees and reaching up to cup her tits.  I was very close, leaning forward  I could smell Liz's arousal, a familiar scent.  The finest perfume comes not from French perfumers, but from the cunt of an aroused, mature woman.  But there was something else and I realised that it was the scent of male arousal, Kev's.   

I too must have been giving off the scent of arousal, certainly my cock was painfully hard.  I was no longer holding it, I was too close to coming.  I leaned back for a wider view and noticed that on the bedside table was Liz's 'phone.  I picked it up and turned on the camera, I could film this.

Liz's body stiffened as the first waves of orgasm hit.  She cried out as it racked her body.  Kev held on, face still buried between her thighs, until her spasms subsided.  Then he moved back and shuffled up between her thighs, his cock wagging with the movement.  Liz reached down with both hands and fed it towards her opening.

This was it.  Consummation.  I held my breath.  Liz lodged Kev's bulging glans at her entrance then released him.  With agonising slowness, he pushed his entire length inside her, accompanied by groans from Liz as his meat stretched hers.  Then they were fucking, vigorously.  Liz's arms and legs wrapped around him.

The man had stamina.  How he managed to fuck for so long without coming, I will never know, particularly if this was as he claimed, his first cunt for six months.  He fucked Liz hard and fast, then suddenly stopped, paused for a few seconds and then rolled onto his back taking Liz with him so that she was now mounted on him cowgirl style.  He resumed his thrusts.

In this position, I was able to see, and film, his cock plunging deep inside my wife, emerging wetly, drawing Liz's clinging cunt lips with it, only to disapear inside with his next thrust.  Liz alternately leaned forwards and kissed him while his hands roamed over her arse and back, straying close to, but never touching the pucker of her arsehole, and sitting up so that he could fondle her tits.

It was in the leaning forward mode, that he again stopped abruptly.  He said something to Liz that I couldn't hear and she reluctantly lifted herself from his cock and shuffled up to straddle his face.  I knew what was happening, I experience the same feeling when she's riding my cock.  To stop myself from coming, I ask her to move up so that I can lick her again.  She always comes when we do this.

Kev had wanted not to come just yet, but wanted Liz to come again.  He was not to know that he could have triggered her orgasm simply by pushing a finger, or a thumb, up her arsehole.

As he once again scoured her cunt with his tongue, his erect cock, wet with Liz's sweet juice, strained upwards.  At first he concentrated on Liz, his hands again roaming her body, but then he moved one hand to his cock and began to wank it.  This also is something that I do, gently stroke my cock to keep it interested until Liz comes, then shuffles down again to re-impale herself, ready to receive my gift of spunk.

But Kev was not stroking gently, he was wanking vigorously. Suddenly his cock spurted, he was coming.  The first spurt fell onto his belly, the second hit Liz on the back of her neck, causing her to squeal in surprise.  I have since downloaded the video from the 'phone and watched it over and over again in slow motion.  Counting the first, pipe-cleaner spurt and the aftershock dribbles, he fired eleven shots.  Most of them landed on Liz's back, coating it with thick, creamy cum, but some went right over her head.  The next day, we discovered some fresh spunk stains on the headboard.

I was impressed,  back in our teens, our peer group would have wanking contests, Kev always won, he always came first and shot bigger loads further than anyone else.  Apparently that had not changed.

But I digress.  As his volley hit Liz's back, she had her second orgasm.  When the spunk volley ended and her convulsions diminished, she rolled off and lay on her back, a little disapointed perhaps that he had not deposited his gift where she was expecting it.  But not as disappointed as me.  What about my sloppy seconds?  I felt cheated.  But I was not to be denied my fuck.  I quickly positioned myself over Liz and she guided my cock into her freshly fucked cunt.  I was balls deep in one thrust.

Frenzied is the only word to describe the fuck, certainly I didn't last a fraction of the time Kev managed.  All too soon, I was spurting my pent up load deep into my wife.  I rolled off, panting.  All was silent for what seemed an age, then Kev collected his discarded clothes, said goodnight and went to his own room. 

We lay silent at first, then burst into a fit of giggles.

"Did you enjoy that?"

I asked.

"I certainly did," she replied.  "But how about you?  You didn't get your sloppy seconds."

I suppose that we should have told Kev that was the plan.  Perhaps his hand finish was not an accident, that he considered it bad form to come inside the cunt of another man's wife?

"You could still enjoy sloppies,"  Liz said softly.  "But not from him."

We fucked for a second time.

I didn't have to wait long for my treat though, after breakfast, where nothing was said about the night before, we agreed to go out for lunch at a nearby gastro-pub, within walking distance.  We were pretty tipsy afterwards and Liz asked Kev if he felt like a repeat of last night.

"But this time," she said.  "I want you to come inside me."

We trooped upstairs again, this time they undressed themselves, this time Liz was naked, but apart from that, it was a repeat.  Liz sucked his cock, Kev sucked her cunt until she came and then fucked her in missionary position, this time emptying himself inside her.  He withdrew and rolled away and I took his place.  His spunk was trickling from Liz's still gaping cunt as I pushed inside.  Fucking a cunt filled with another man's spunk is everything it's made out to be.  And more.

"That was just awesome."

Said Kev.  And went on to say that he had never experienced it.  That evening, we rectified that  with me going first, then Kev experiencing the unique sensation.
