My wife Denise has a very demanding and high level job.  It has taken the pair of us and our son all around the world.  It was the first time that we had left David at home on his own.  Being eighteen I thought the worst he could do would be to have a few mates around and sleep with his gorgeous girlfriend Sasha.  We had been in San Francisco for just five days when the business that Denise was there for concluded rather suddenly.  I expected that we would return home, but after a phone call my wife told me that she would be flying to Spain and as there was only one seat left on the plane I could either wait for another flight or return home on my own.  I opted for the later as I found Spain to be boring on my own the last time we were there unless you’re a beach bum, and that I am not.

On getting back to Heathrow, I was soon in my car heading for home and wondering what I would find.  After the two hour drive all I wanted was my own bed as I was tired.  Imagine my shock to find three lads and two girls in my lounge, all in various stages of undress and sleeping.   It was obvious that there had been a fair bit of shagging going on.  There was even a couple on the stairs that I had to move to allow me to continue up the stairs to my bedroom.  The couple grabbed their clothes and headed for the front door.

I made use of the bathroom before entering my bedroom.  I was confronted by two lads and two girls in my bed.  The one lad woke and pulled his girl out of bed with him and quickly left.  Not wanting to make a fuss at just after three thirty in the morning I stripped off and slipped into my own bed next to the two left in the bed.  I turned off the bedside light and enjoyed the warmth that was created by the couple that had just left.

I found myself rolling towards the lad and girl.  Fortunately it was the girl that was between us.  She was laying on her side with her back to me.   As our bodies touched I couldn’t help but reach around and feel a nice pair of tits.  The girl wriggled her arse against me causing my cock to start to grow.  With that the girl reached backwards and took hold of my cock and said, “What again.”  It still didn’t stop her rubbing my cock that was already hard.

Then to my surprise she wriggled her arse some more and then the next thing was my cock was slipping into this young woman’s pussy.   At this point I didn’t know what she looked like or who she was as she was facing away from me, but she was now starting to hump herself at my cock that was almost fully in her pussy.  Tired or not, it’s funny how all of a sudden one has the energy to fuck.  I was now humping back at the pussy engulfing my cock and fondling a small but nice pair of tits.  The lad next to her suddenly said, “Can’t you two give it a rest,” as he rolled over to face away from the girl.

It was several minutes before I felt her pussy tighten and practically drag the cum from my cock into her pussy.  We lay still recovering in that position with my cock still embedded in her pussy until it had shrunk enough that it just slipped out.  I lay there thinking about what I had just done, but it didn’t stop me dozing off to sleep with a huge smile on my face.

When I woke it was just before eleven o’clock by my bedside clock.  I was now facing the opposite direction away from the girl and lad.  It was a very bright day and there was lots of sun shining into the bedroom as I started to turn over to see who I was in bed with.  I got the shock of my life.  The girl was on her back and I could clearly see who it was.  It was Sasha my son’s girlfriend, but the lad that was in my bed was not my son.  I thought that I would quickly get out of bed and Sasha would be none the wiser that it was me that fucked her at three thirty that morning.

It was no use.  The moment I started to move Sasha’s eyes opened.  She looked almost as shocked and surprised as I was.  I was quickly getting dressed not knowing what the hell to say to Sasha.  She was routing around trying to find her clothes as I left the room.  After a trip to the bathroom, I went down to the kitchen.  The lounge was now free from bodies.  I started to make myself some breakfast when Sasha came into the kitchen.  I offered her some breakfast and she accepted my offer.  She sat quietly as I made tea and breakfast.

Then as I sat facing her, Sasha suddenly said, Was it you that fucked me this morning?”  I pointed out that it was more a case of her fucked me as she had started things off, even if I finished them, and came in her hot little pussy.  Sasha said that I could never let David know I had fucked her.  I pointed out that she could never tell Denise.  We agreed to keep it between ourselves.  At that point we were joined by another couple who I didn’t know and Sasha quickly pointed out to them that I was David’s father.  As I cleared our breakfast things away, Sasha and the other girl started to clear up where they had drinks cans and snack foods before sleeping in my house.

The house was soon pretty straight and Sasha asked where the hoover was.  While I put the stuff either for recycling or trash out, Denise started hoovering the lounge.  We were shortly joined by David and some girl I had never seen before and another couple that had been in the spare room.  All but David and Sasha soon left.  David started to apologise to me for having a small party.  I stopped him and told him there was no damage done and all was straight, and besides I was young once.  Sasha had a knowing smile on her face.

I pointed out that all the bedding would need washing before David’s mother got home.  David went off and stripped all the beds of sheets, pillowcases and duvet covers.  He put most of it into the washing machine and I had to set it up and start it as David had no idea how to use one.  It was fast approaching midday and David was rushing around to collect things for work.  He had a part time job besides his apprenticeship.  He kissed Sasha and told her he would see her later as rushed off.

The moment there was just Sasha and me left in the house, she wanted to try to explain about the previous night.  She started by telling me that although she and David were seeing each other it had never been an exclusive thing.  I was a little surprised.  Then she was telling me that all the people that had been in the house were all friends of theirs, and they had all been careful with our stuff.  Their only crime was to sleep over in my house.  I told Sasha that I wasn’t upset or annoyed and in fact I had enjoyed it even if I had been tired.

I don’t remember quite how it happened, but Sasha was kissing me and thanking me for not being angry with them.  Well, one thing led to another and I was soon fucking the hell out of Sasha again.  This time in the doggy position with Sasha’s top half on the sofa.  It wasn’t the quick bang that I had with her earlier that morning.  It was a good long shafting that I gave her before letting go another load of cum deep in her pussy.  Afterwards Sasha said she needed to go home.  Before she did she stroked my cock and gave me a sexy kiss telling me she would be back for more of what we had already had.

It was nearly a week and a half before Denise arrived back home.  David and I made sure the house was spick and span.  Denise commented that there couldn’t have been any parties.  David and I sheepishly told her she was right.  The only thing different was that Sasha was now staying over in David’s room two or three times a week.  Denise seemed surprised at that, but not upset.  I think Denise thought that I wouldn’t have allowed that in my house.  When we were on our own Denise said it reminded her of us sneaking around and sleeping at her mother’s house before we got married.   Then she dragged me upstairs to bed for a very enjoyable shag.

It was around six or seven weeks later still after Denise’s last trip, she was jumping into a taxi to get to the local airport for a flight to Germany.  Sasha had stayed over that night.  As I waved Denise off David was also rushing off to work.  I had some work to do, but as I worked two sometimes three days a week from home, I was still in my PJ’s and dressing gown.  Having seen the pair of them off I went off to the bathroom before getting changed and starting work. 

I had forgotten about Sasha and was stood in just my PJ’s shaving when she entered the bathroom.  I had forgotten to lock the door.  Sasha was wearing one of David’s T shirts and a pair of panties.  As I stood shaving, in the mirror I saw Sasha pull her panties down and sit down on the toilet and start peeing.  My poor cock was starting to tent the front of my PJ bottoms.  I watched in the mirror as Sasha stood and wiped herself and pull her panties back up.  By this time my cock was at full mast.

Then Sasha was behind me reaching around and grabbing hold of my stiff cock.  “Told you I would be back for more,” she said.  As I turned around, with shaving cream still on my face, Sasha dropped to her knees and eased my cock out of my PJ’s and slid it almost all the way into her mouth and proceeded to give me, what was by far, the best blow job I had ever had.  Sasha stopped just short of me coming and stood telling me that I knew where to find her.  With that she wiggled her sexy arse out of the bathroom. 

I very quickly finished shaving and rushed to find Sasha laid on top of David’s bed.  She still had the T shirt on but the panties had gone and she was fingering her own pussy with her eyes tightly closed.  I climbed onto the bed between her legs and pulled her hand away as I plunged my tongue into her juicy glistening pussy.  Sasha squealed at my first contact with her pussy and then just lay there moaning as I treated her pussy to a good licking and sucking.

Sasha seemed to especially like when I sucked her clitoris into my mouth and wiggled it around with my tongue.  After several minutes of licking and sucking Sasha groaned that she was coming.  I doubled my effort on her pussy as she rode out her orgasm and thrust her pussy harder at my face.  Then as she fell back all lose and floppy I crawled up her body, sucking on a tit that I bared, then lining up my cock and sinking it slowly into her pussy.

Sasha lay still, but groaned loudly as it penetrated and sank almost fully home.  Then as I started the humping movement, Sasha started to move with me.  At first it was long slow thrusts but as time went on so the thrusts became shorter and faster.  Then finally I was slamming away at Sasha’s pussy just as fast and hard as I could.  Needless to say, that didn’t last long before I shot another load of cum deep into her pussy.

Shortly after we had cleaned ourselves up Sasha dashed of to college.  I struggled to concentrate on my work.  All I could think about was fucking my son’s girlfriend.  It didn’t help that at lunch time Sasha returned and we fucked again, this time in my bedroom.  As you will know sex is addictive and your left afterwards wanting more when the euphoria wears off.  It was the same with Sasha, we couldn’t wait for the next opportunity to fuck her again.

I didn’t have to wait too long.  On the Friday David asked if he could have some friends around on Saturday evening.  I quickly told David that he could.  I just hoped that there was a chance of getting to fuck Sasha again.  At the start of the evening there was around a dozen couples arrive.  Most of them were unknown to me.  There was also a single male and two extra females.  As the drinks flowed the lads behaviours deteriorated with kissing and groping the young ladies.  I found myself sat watching their antics and getting an erection.

Fortunately, we live in a detached house with a reasonable amount of land around it, and I knew that the loud music wouldn’t upset any neighbours.  Some of the girls were up dancing rather provocatively.  Then one of the girls tripped and landed in my lap.  To my surprise she made no effort to extract herself from my lap.  Instead, she wriggled her arse in my lap.  She must have felt my erection pressing against her arse.  Then as someone turned the lighting down, the girl turned her head and kissed me fully on the lips.

As much as I enjoyed it I just hoped that David hadn’t seen what had happened.  I needn’t have worried as he had already disappeared upstairs, but not with Sasha.  Knowing that I kissed the girl back and fondled a rather nice firm pair of tits.  The room was emptying out somewhat, and I worried that I might have to evict someone to get to my bed.  As nice as it was I eased the young lady off my lap and went to see who if anyone was in my bed.  I was in luck, I was just in time to stop a couple from making use of my bed.  As I entered the room, the girl that had been sat on my lap, followed me into the room.  As the other couple left, she shut the door and started to undress. 

My cock which had softened a little sprung straight up again on seeing this lovely young lady baring herself for my benefit.  I was quickly undressing as I wasn’t about to miss the chance for fucking a lovely young thing half my age.  Just minutes later I was between her legs giving her pussy a good seeing to with my tongue as she sucked my cock.  I was now on my back enjoying the young ladies sweet pussy in my face as well as the sucking she was giving my cock.  I didn’t hear or see anyone else enter the room, but as the young lady let go of my cock, another girl was penetrating herself on my very stiff cock.  Whoever it was, was giving my cock a damn good ride as I continued licking and sucking at the pussy on my face.

The girl on my face came strongly causing a gush of her juices to flood my mouth and soak my face.  Then as she stopped trembling and groaning she moved away.  It was now that I saw Sasha firmly stuck on my cock riding herself towards her orgasm.  As her pussy tightened and gripped my cock I started jerking as I shot my load in Sasha’s pussy.  Sasha slumped down on top of me, recovering from the heavy panting she was doing.  Both girls cuddled up to me and there was some giggling between them.

It was a while later when a hand grasped my limp cock again.  I didn’t know which of the girls had grabbed my cock, but it was nice whoever it was.  I was slowly getting hard again.  As soon as I was hard enough the first girl declared that it was her turn.  It was she that had played with me to get me hard again.  Sasha lay watching as the young lady straddled me and lowered her pussy onto my cock and started to ride me.  As the girl bounced up and down Sasha reached up and played with the girl’s tits.  The girl bent her head forward and started to kiss me as she rode. 

Then she was unable to keep up the kiss as she started to ride harder and faster.  Sasha wriggled tighter to me and as she continued playing with the girls tits she started to kiss me.  The girl riding didn’t last long enough for me as she groaned and came.  Sasha pushed her off me and again straddled me and plunged her pussy down on my cock.  I don’t think Sasha came, but I did, pumping another load into her hot pussy.

We all cuddled up together now under the duvet.  I was woken around two in the morning as the young lady got out of bed and dressed.  I watched in the limited light as she left.  It must have disturbed Sasha as she wriggled around and then cuddled tighter to me.  We both settled back into sleep.  I woke again at seven o’clock.  I was still cuddled against Sasha, and in fact had a hold of one of her tits.  As I tried to move it woke Sasha.  She immediately kissed me and reached for my cock.  It wasn’t hard but Sasha soon changed that as she kissed me and played with my cock.

Just ten minutes later I had Sasha on all fours and was fucking her hard and fast from behind.  It was one of those fucks where two people are in perfect sync.  We banged against each other in perfect rhythm.  I was reaching around and playing with Sasha’s clitoris and she was reaching back between her own thighs and  playing with my balls as we fucked each other.  Then on cue we both came at the same time.

We lay in a tangled heap of arms and legs for a good fifteen minutes.  Then Sasha got up and dressed saying she didn’t want David catching her in my bed with me.  We were both sat eating breakfast when others that had stayed woke and joined us.  A sleepy David joined us with what I suspected was the girl he had slept with.  Sasha was sat next to another lad and girl and I hoped that David thought that Sasha had slept with him.

I was surprised that there was very little clearing up needed and David was putting the washing machine on for his sheets and thing as well as those from the spare room.  Again like the previous party David was soon dashing off to work leaving me with Sasha and another couple.  The other couple soon gave their thanks as they cuddled and kissed Sasha before leaving.  It was just minutes before I was back in bed with Sasha fucking her long and hard again.

I managed to sleep with Sasha quite a few more times and twice more at parties.  David joked with me and told me that he wouldn’t tell his mother that I had slept with some of his friends.  I think he had just guest as he hadn’t actually seen me with any of his friends.   He still didn’t seem to know that I had fucked Sasha or he hid that. 

Anyway, things seemed to change between David and Sasha.  It came about after a row they had.  Whatever or whoever it was about seemed to bring the two of the closer together.  In fact, David stopped sleeping with other girls.  I think he thought that he was now in a monogamous relationship with Sasha.  Little did he know that Sasha was still dropping in on me and we were still fucking like rabbits every time she dropped in.

It was when my wife had returned from Holland, and as it was her birthday, I took her, David and Sasha out for a restaurant meal.  During the meal I spotted that Sasha was wearing an engagement ring.  Then David dropped the news on us that he was getting married to Sasha.  Then Sasha dropped even bigger news on us.  She took something out of her handbag and handed it to Denise.  Denise and Sasha were stood up cuddling, squealing, and shrieking.  It was several moments before Denise handed me what turned out to be a sonogram.  I was stunned.   Sasha was pregnant. 

My wife seemed made up over it.  I was especially stunned as I knew there was a chance that the baby might be mine. I had to show that I was happy so not to let our dirty secret out of the bag or ruin the evening.  The rest of the evening was all baby talk or how we could help them with their wedding as well as getting their own place.  I was glad to get home as I thought my wife would have calmed down from her excitement.  She didn’t and you would have thought it was her that was pregnant by the level of excitement.  Mind I was happy that that excitement generated one of our best fucks in a while.

It was about a week later when my wife was off on her travels again, and David was at work, Sasha dropped around.  All the talk about babies, marriage and a new home were lost as we ended up in bed and I was ploughing Sasha’s now pregnant pussy harder and longer than I had ever done before.  Afterwards Sasha said we should stop seeing each other.  I agreed, but it didn’t stop her turning up a few days later still.  I tried to tell her no and that we must stop, but the fact that she got on her knees and started to suck my cock soon killed any resistance. 

We fucked all the way up until she went into hospital to be started off.  My son? or grandson was born and everyone said just how much he looked like his grandad.  David, Sasha, and Alun moved into their new home.  It was three weeks later when they got married.  I thought that would stop our cheating.  Well, not quite.  Sasha turned up and told me it was one last time and to make the best of it.  I did.

I fucked her both in the missionary position as well as on her back with her legs up on my shoulders.  Then as she dressed she told me that was it as far as she was concerned, but she had a friend who was looking for an older man to take care of her needs.  For the next fifteen years I fucked Sasha’s friend whenever we could, which was quite often with Denise away, and no David to catch me cheating.

Then the chance for early retirement came and I grabbed it with both hands thinking I would have even more time for shagging.  I did for almost three more years, but then my wife was offered the same, early retirement.  That brought my cheating to an almost full stop.

David and Sasha have three children now.  Although they are all fast becoming adults, Denise and I often take them out for trips and treats even though they are now teenagers.  It often brings back memories of the times I spent with their mother.  After what Sasha said was the last time, as far as I know she has never cheated on David since that last time.  They seem so happy as a family and I am glad that we never got caught and it never impacted on their family or David’s relationship with Sasha.

Whilst I had enjoyed Sasha and several of their friends my own marriage is still good.  I have now settled down to just sleeping with Denise.  I still have my memories though.
