I was in a state of shock.

Sam, Bill's supposedly staid wife, friends of some fifteen years was sat astride me. She was facing me, a look of lust and pleasure on her face and sinking one very hot, wet, pussy onto my very erect penis. She moaned softly as she took me into her, her dress bunched up and covering our 'joint' situation. The sight of her silhouetted against the bright sunlight of the garden, and the realisation that she had no briefs on were what had given me that almost instant erection in the first place.

But let me go back a little bit and offer something of the lead-up to my confusing situation.

I have been married for over twenty-five years to my lovely wife Pam. When we married in our mid-twenties I, like a lot of men in my age group had 'played the field.' Not excessively, but still, with the current threat of aids, more than would now be considered either wise or safe. Pam had had lots of boyfriends but was a virgin who had 'saved' herself for her wedding night and me her husband to be. Well, she had saved herself, but we didn't actually make the wedding night. While engaged we had ended up in bed one wet, wintery Sunday afternoon. Once she had discovered the joy's of sex we had fucked like mink ever since!

We only had one minor problem, I am fairly well built and until after the birth of our first son, Pam being fairly petite, could only take about six of my eight inches, depending how excited she was. Having never slept with any other man she didn't have anything to compare me with and so was unaware of my size being anything other than normal. I was aware that I was rather larger than average and that quite a few of my girlfriends had been unable to take my length. It's a myth folk's that girls can take a big dick all the way in! A very few can, but even then you have to be very gentle to start with, otherwise it's 'hurtsville', a terrible turn-off and yet another 'ex'.

So our sex life was/is exciting if somewhat conventional. My joke of going to a wife-swapping party, throwing the keys in the middle but coming away empty handed as no-one would give me a Porsche for Pam had worn a little thin over the years.

But back to the present. Here I was in the lounge of our very good friends with Sam, short for Samantha, impaling herself on me, taking all of me, bouncing on me and rapidly approaching an explosive and mind blowing orgasm of colossal proportions.

Me? I was about a nanosecond behind her and with a slightly strangled moan I shot one helluva load deep in her spasming pussy. The feeling as her hot, very tight sheath (they had not had any children) milking me of the last of my semen was incredible. I hadn't come like that in years.

I lay there under Sam for a few seconds gathering my wits and then began to panic.

Where were Pam and Bill?

They had only gone upstairs so that Bill could show Pam some changes he had made to the bathroom and had only been going to take a few moments. Sam had leapt on me as soon as they were out the door. They must have heard the noise we made, after all we hadn't exactly been quiet. They would be back any second...

Sam lifted herself off my rapidly shrivelling penis, briefly adjusted the chiffon fabric dress that had started all of this then leant forward to take my penis in her mouth and cleaned me with a neat, rapid touch of her tongue and lips and zipped me back into decency. Then she leaned forward and kissed me full on the lips. A big wet, slobbery, luscious full-on-the-mouth kiss. For the first time ever I tasted my salty cum on her lips and tongue.

Pam? Pam would never have done this.

Staid Pam, would never eat me to the point of cumming. I often went down on her and ate her to a climax where she came so violently I got ear-ache from her clenched thighs as she screamed at me to stop. It was a bone of some contention that reluctantly all I got in return was a very little oral ministration. A kiss and a lick at best, still that was really the only thing I missed out on. Given my length and girth I have never even given anal sex a thought, let alone been tempted to try.

But I digress. Back to the now. What the hell was going on? What had led to this?

We had visited here before. In the past both with and without our children, but this time Pam and I had come to see the finished job Bill and Sam had made of their new house. He was one of these sickening characters who could turn his hand to anything, and had just about rebuilt the inside of the old house they had bought for a song. It was superb. I had to admit he really was very good. As DIY is not my forte I didn't begrudge it them at all. In any case they really were a very nice couple in all senses of the term. Sam had grown up a few doors away from us at one time before we moved house. When she and Bill, they had never had eyes for anyone else to my knowledge, had been walking out they had been only too happy to babysit on the odd occasion we had needed it. It gave them somewhere to discreetly make out I guess.

So we had watched them grow up, been to their wedding, been to their house, numerous times and now I had just fucked the ass off her.

She kissed me again and said, "Bill and I weren't the only ones who planned this."

Then she grabbed me by the hand and almost ran, barefoot with me through the house. She placed a finger on her lips as we quietly climbed the stairs. When we reached the top we could clearly hear the sounds of obvious lovemaking coming from their bedroom. We reached the door and my feelings were overwhelmed by the sight of Bill and Pam fucking. Pam was on top, one of her favourite positions, both uncaring. Their eyes unseeing.

As I watched mesmerised, I realised I had never seen another couple fucking in the flesh, as it were. At the same time as we watched Sam was stroking the growing bulge in my crotch.

Jesus this was hot.

At fifty years old my time to recover could normally be measured in hours not minutes, or almost seconds, but here I was rising to the occasion again.

Bill and Pam were naked. Pam was rising almost to the top of Bill's shaft and then plunging down, taking him all. She was leaning forward so that he could suckle her beautiful tit’s. She's no Pamela Anderson, but then I didn't care. She was, had been, all mine. Bill's penis wasn't as long as mine, but he was about the same size round and Pam, my sometime staid wife was far gone, way beyond caring.

As I stood gawping in the doorway, my mouth wide open I have no doubt, I became aware that Sam, now naked, was undoing my shirt. In fact she had it undone and was now attacking my chinos with equal vigour. I, half aroused from my state of further shock and stepped out of things to help, still totally taken up with the scene of sexual frenzy in front of me.

I was almost unaware of Sam taking my now rock hard penis in her mouth and sucking it all in, all the way into her throat. The feeling was incredible, hot, cold, I can't describe the sensation. I was in total sensory overload.

Sam pulled me down on top of her and pushed me down between her legs to where the beautiful entrance to her vagina was totally shaven. The smooth labia and her mons an almost fiery shade of deep, aroused pink. I couldn't help myself. I fell on her and ate her out like a thing possessed! The taste was exquisite. A mixture of her wonderful honey and my own salty semen of less than ten minutes ago. Was it only that short time? My balls seemed full to bursting point again as I lapped at that wonderful hot, squirming pussy, Sam screaming as I brought her to another crashing climax.

She rolled over and reaching back pulled me to her and into her from behind, As we fucked, Sam pushed hard back into me and I held her marvellous hanging breasts as she lowered her head to the bedroom rug to get a better, deeper angle.

At eye level on the bed Bill groaned as he arched upwards into Pam who had cum just before him, her mouth open in that soundless scream I knew so well. As she slowly came down from the heights she reached across and squeezed my hand tightly.

Underneath me Sam jerked like a puppet as she came again. The combination was too much and I also groaned and sprayed my white hot semen into that delicious pussy. Still coupled Sam and I slid to the floor physically shaking from the emotion and effort of the moment.

As I shrivelled and slipped out of Sam for the second time in a matter of minutes we lay still totally spent. Bill and Pam's heads appeared over the edge of the bed looking at us. They both had a shit-eating grin on.

Pam spoke first "Love you darling.”

Then, “How are you feeling?"

How do you answer that truthfully when the conventions of normal wedded behaviour and the idea of a twenty-five year stable marriage has just crashed out the window in a sheet of adulterous flames!

"Shocked! Bewildered! Fucked! Very fucked! I think we need to talk!" I said.

"Tell you what," Bill said, “I’ll get a bottle from the cooler. Sam, give me a hand with the glasses will you love.”

As they disappeared Pam looked at me and said, "Are you mad at me?"

"God no," I replied. "But what happened? Why? I mean, what lead up this? It wasn't spur of the moment, you obviously planned it."

"Well! Yes, in a way," Pam replied. "You remember I had a day off the other day and I said I was going to call on Sam."

"Yes.” I said.

“SoI did and just dropped by. As the kitchen door wasn't locked I just walked in shouting, ‘Coo-ee' and ambled into the lounge to find Sam on her back with her ankles behind Bill's neck and Bill and she cumming. Very noisily. I should have walked out but I'm afraid I just stood there and watched. As they came back down I realised I was more turned on than I ever had been, I was dripping! Sam just grinned and told me that if I stood like that much longer it would be my turn as Bill was never satisfied with just once. Anyway she might have cum, but she didn't think he had."

"Sven, love, I couldn't help myself. I was so turned on I had to have him. He was offered on a plate. Sam helped Bill enter me and I came almost at once, then just kept cumming until Bill shot his load. It was nearly a quarter of an hour before I stopped shaking."

"It turns out that they are into very selective swinging and had been thinking of approaching us for some time. I'm sorry if it was wrong, but it was so good, I wanted to tell you but I never got the chance to broach the subject. Then we set up today and we thought it was make or break. I know you had always cast an eye over Sam. In fact you once said you fancied her something rotten. I couldn't get a chance tell you how much I wanted Bill again.”

At that point it all became too much and Pam started to cry.

Sam came back in the room and she and I put our arms around her and told her to stop worrying and I said that ‘I forgave her - I think!’

Sam pointed out that, "This fellow,” and she kissed the end of my again erect penis, "certainly does!"

I simply couldn't believe my physical reaction to the situation. Here I was hard again.

Bill arrived back with the bottle to find Sam sucking on my penis which was definitely ready for more, even if I still didn't believe the situation.

Pam held the glasses as Bill poured out some wine. We persuaded Sam to leave off for a little while and we drank a toast to our new found freedom and future lifestyle. Sam took a mouthful of cold wine and bending down slipped my half erect penis back into her mouth. My mouthful of wine got sprayed everywhere as I choked on it. For the moment it would seem that she and Pam had other ideas and it became obvious that Pam and I would just have to leave our chat until later.
