My partner Greg and I first met when we were in the Ingleborough fell race a few years back.  As it happened, we had much in common and now we live in a croft on the north coast of Scotland.
Back when these events happened, we were both in our early 20’s.
 
Just after we started courting Greg bought an old BSA 650 cc motorbike that was a joy, for me, to ride pillion on.   We had only been dating for a few months and I have to say that the sex was fantastic. We would ride out into the countryside, park the bike and then have some great sex before jumping back on the bike again and heading home.  He dropped me off at my digs and the sound of his throbbing engine as he rode away always made my heart skip a beat. 
About 3 months into our relationship, I had notice to quit my digs on account of the landlord selling up. So it was that I moved in with Greg at his mum and dad’s house.  His mother was a tiny homely lady about 45ish but could easily pass for somebody much younger. Charlie, Greg's dad, was a big guy in his 50’s.  He was like a bear.
Although Greg and I shared a bedroom, sex was not really on the agenda to start with seeing as how his mum and dad were just the other side of a partition wall.  Having said that, his mum and dad were very active at night time which was the only time that Greg and I could indulge ourselves indoors hence our forays out into the countryside. 

First thing in the morning Greg and his dad would just wonder around in boxers and vests where as his mother walked around in her night dress then after breakfast everybody would have showers and get dressed.  Charlie’s boxers did little to hide the fact that he was very well endowed.

I was between jobs so nothing to do all day.  Greg's dad didn’t need to work on account of his army pension plus he dabbled in the stocks and shares.  After Greg had left for work his dad would busy himself most of the day around their small holding while his mum and I would sit and chat about all kind of things.  Over the next few months, as we got to know each other better, we talked about more the personal stuff.  She apologized for the noises that would come from their bedroom for an hour or more most nights. She said that Charlie was insatiable and that we mustn’t be coy about having sex when they were in the next room. 

One time Connie walked into our room just after Greg had gotten out of the shower.  As he was drying off, I had grabbed his cock and started sucking him off.  I must have gone bright scarlet as I saw Connie out of the corner of my eye when she walked into the bedroom. Greg didn’t even bat an eyelid; he just kept his cock in my mouth.  Connie said “Here’s you clean laundry love” then she added “You make a beautiful couple”.  She watched for a few moments before smiling at me then left the room.   With that Greg grabbed my head pushing his cock deep into my throat then shooting pretty much straight away, I am sure that he got off on being caught by his mum.

One day Connie told me about when they used to have some of Charlies old army mates stay over and how she looked after them.  It would usually be one or two now and again. This talk always got me aroused and planted the seed in my mind about having threesomes or foursomes, a fantasy that one day I would invoke.
By now I had fallen into their morning habits.  I would often just walk around in a pair of Greg's boxers and a vest.  It wasn’t erotic or rude, it was just a natural thing to do.  Greg and I were now enjoying proper fuck sessions at night as there were no more inhibitions since his mother caught me giving him a blow job.  Sometimes I would be extra vocal knowing that they could hear us in the next room.  His mother was also not averse to letting out a stream of profanity during their love making.  I am sure that father and son felt like they were in competition. 

I could tell that Charlie was a big boy in the down-stairs department.  One time I was bursting for a wee, I literally ran into the bathroom, dropped my pants, sat down and as my pee flowed out of me, I noticed Charlie standing in the shower.  I was in full flow so no chance of stopping. I doubt that he would have seen me because I could see through the frosted glass that he was holding his cock and wanking off.  Oh, how I wanted to open the shower door and jump in there with him but I didn’t, I crept out and closed the door.  My heart was racing.  I hadn’t been able to make out any detail but I knew that he was big, bigger than Greg and Greg has more than enough to satisfy me.

Greg had to go away to work away for a week.  Our last night of rumpy bumpy was incredibly active and seemed to go on long into the night.

Bright and early the next morning Greg fired up his motorbike and off he went.  I felt a pang of sadness and I had a silent tear on my cheek as I watched him disappear down the road.  Charlie came up behind and wrapped his strong arms around me.  “Don’t be sad lass, it’s only for a week”. 

Listening to Charlie and Connie going at it every night kept my libido in overdrive.  My toys took a right battering.  I would strip of naked and lay on the bed with my legs wide apart and I would fuck myself with my best friend, an 8-inch rubber vibrating cock.  It wasn’t as good as the real thing but it was better than nothing.  A couple of times during our chats Connie would mention that listening to my ooo’s and aaaah’s and the buzzing of the vibrator would spur her on with Charlie.  On the 4th night the battery went dead just as I had finished cumming for the umpteenth time.  I fell asleep with it still in me.  When I awoke in the morning it was on my night stand and I was still laying on the top of the covers naked.  That morning Connie told me that Charlie had popped his head around the bedroom door to see if I was OK. Upon seeing the state that I was in he called her in.  As he removed the vibrator from my pussy he got an erection.  So Connie took him in hand and wanked him off while they both stood by my bed ogling me.  I did wonder why there was something sticky on the floor beside my bed.  I gotta to say that I didn’t find that at all creepy, fact is that it turned me on.

On the fifth night I heard Charlie and Connie talking in the next bedroom which wasn’t hard because the walls are so thin.  Charlie said that Greg had pulled a blinder having me for his girlfriend.  He went on to say that he would love to add photos of me to their collection.  “Oh yes” Connie said “I will mention it to her tomorrow if I get the opportunity.” 
Photo’s? I thought….Mmmm I want to know about those photo’s. 
Then the fucking began again.  Oh boy, they were really going to town tonight.  Connie was her usual vocal self and I am sure that Charlie called my name out a few times. 

The next morning after breakfast I tactfully brought up the subject of photos with Connie.  She went a little red and then told me that Charlie liked to take photos of her, especially if Charlies old army mates were staying over.  After a while I managed to coax her into showing me some of the photos. 
She booted up their computer and worked her way through a couple of folders and clicked on it.  There were lots and lots icons that opened up photos mainly showing how accommodating Connie was to Charlies friends. 
“There you go” she said “I will go and put the kettle on while you have a little look through.”

As I clicked on the icons and the photo’s opened up, there were photos of her with one guy or two guys looking after their cocks and they were looking after her.  It was very erotic going through them and my pussy was aching for some of that attention.  ‘Oh Greg, please come back soon’ I thought.
Then I saw a folder called Charlie.  I just had to open it.  I clicked on the first couple of icons and up popped pictures of Charlie in all of his glory with his beautiful cock on display.  I was right about the size of it.  It was quite fat and about as long as Greg's.  Behind it hung a huge pair of balls.  I am sure that I nearly came right there and then without even touching myself.  I opened up a few more icons and saw Charlie with another woman.  Beside it was an MP4 file so I opened that up as well.  There was Charlie standing before a blonde woman who was on her knees and sucking his cock.  His cock looked humongous in her petite hands.  They both kept looking into the camera and smiling.  The sound quality wasn’t very good.  Then into shot came Connie who was naked.  She went over to Charlie and kissed him while her hand went down to fondle his heavy nut sack as the blond lady sucked his cock.  I could hear Charlie say that he was going to cum, the blond lady took her mouth of his fat cock and he shot his load over her face and tits.  Getting caught up in the moment I came as well.  I tried to stifle my scream but as I came down, I heard a noise behind me “Do you like what you see lass?” I heard Charlie say.  I turned around and I knew my face was as red as a beetroot.  Behind me stood Charlie and Connie.  Connie had her hand down Charlies pants and she was clearly massaging his cock.
I tried to speak but I couldn’t, the words were stuck in my throat.  Charlie just smiled while Connie left to get the coffees.  Charlie’s cock was pushing out the material of his sweat pants, it was close enough for me to reach out and touch, I thought about it but I didn’t even though I was mesmerized just looking at the front of his sweats. Then Connie came over with the coffees and sat down beside me as if nothing had happened.  The MP4 had finished.
“You look a little hot and flustered” Connie said to me as she patted my leg “Greg will be home in a day or two and he will sort you out.  In the mean time we will take care of you”.

As I regained some sort of order in my head I wonder if what had just happened had really happened.  It was crazy but even so, I couldn’t get the thought of Charlies cock out of my mind.
“I heard Charlie say that he would like to take some photos of me” I said to Connie “What sort of photo’s?”
“I think that you can guess Mal” she said.
“What…naked pictures of me?”
“Sure, why not?”
We left that comment hanging and the thought off Charlie taking naked photo’s of me was playing in my head although it would just have to be photos and no touching but first I would have to run it past Greg I thought.  Greg would think that this is so messed up I thought.

Later that evening as I lay on my bed Greg phoned to say that he had to stay on for another couple of days.  For fucks sake, I was barely hanging on as it is.  I was pissed but I let it go.  During the conversation I mentioned to Greg about the photos. 
“How did you hear about them” he asked.
I didn’t really know what to say but I couldn’t lie, I told him that I had heard Connie and Charlie talking about them and I had seen some of the photo’s that they had taken.  I said that I hadn’t realized that they were swingers.  Greg said that he wanted to be here when they took photos of me.  It dawned on me that he knew that they were going to take photos of me at some time, ‘what sort of family is this’ I thought? 

I lay back on my bed letting this stuff run through my head.   I was as horny as fuck so I had to take care of myself. Somewhere I am sure that I heard a phone ring but I didn’t care. With new batteries in my best friend, I lay back with my legs spread wide and rubbing my pussy for all it was worth.  I came so hard, I arched my back and screamed.  Fuck Fuck Fuck.  Holy moly, I came like I hadn’t cum for quite a while.  
As I settled back down there was a flash then I caught a movement at he bottom of my bed, Charlie was standing there bollock naked with a camera in his hand and Connie was wanking his beautiful cock.  Oh fuck, my pussy is itching for some of that cock meat.
“Greg phoned us to say that you wouldn’t mind us taking some photos of you dear” Connie said “We will email this one off to him right now”.
I just smiled and I knew that I was going to end up getting Charlie’s cock into me before Greg came back and there was nothing that I could do about it.

For the next couple of days, I made sure that Charlie and Connie knew that I was hot and horny for anything.  During our morning coffee chats Connie would recount some of her adventures with Charlies friends. 
Having now seen the size of Charlies cock I asked her how, seeing as she is so petite, did she managed to take all of his fat cock in.  She put it down to doing gymnastics when she was younger.  She said that it gave her great muscle control.
“But it must hurt” I asked her.
“It did in the early days of our courtship” she said “but it was a really nice kind of pain and once he had it inside of me, I just felt so full”
“I bet you did” I said.  As much as I enjoyed hearing her recount things I couldn’t help wondering what it would feel like to have that monster inside of me.

‘2 more sleeps to go and Greg will be home’ I thought as I lay naked on my bed that evening.  My telephone rang, it was Greg “Hi honey” he said “How are you holding out?”
“It isn’t easy” I replied.  My pussy was getting wet again and my nipples were starting to ache.
“Thanks for the photo that dad took last evening” he said “I had to knock one out while I looked at it and wondering if you have been up to anything else”.
“To be honest Greg, your parents don’t help any, they spend all night fucking and I have to lay here listening to them with only my best friend for company.  I have already changed the batteries 3 times”
“Huh, that bad, eh? I thought that dad would have tried to get his cock into you by now, he must be getting old” Greg laughed which was no help to me in my state and only served to bolster my libido up thinking about Greg's dads fat cock.
“I reckon that I can hold on for another couple of days” I said.
“I bet you can’t” Greg goaded me.
“That sounds like a challenge to me”.
“Take it anyway you want” he came back with “Tell you what, if you can hold out until I get back I will take you to the Maspalomas and leave you alone for 2 hours in the dunes”.  The dunes at Maspalomas are a haven for guys seeking easy ladies.  Greg and I have often watched videos about what goes on there and we always have a great fuck afterwards so he knows that my fantasy would be to visit there.
“And if I can’t hold out?”
“I am, sure that I will be able to think of something”
This sounds like a win win to me.  By now my whole body was throbbing and aching for attention.  Connie and Charlie were hard at it again. 

A strange desire had swept over me, I kinda had Greg's blessing so I wanted to see what was going on next door.  I crept down the hallway, Connie and Charlies bedroom door was wide open.  I peeked in and saw Charlie laying down and Connie riding his cock like a rampant mare.  They were lost in the moment.  Between the Ooohs and Ahhs I could hear Charlie saying things like what he would like to do with me, he was using my name a lot.  Connie was egging him on by saying things like “You want to fuck her and cum in her cunt you dirty old man?  I bet you would fuck her cunt all night long finger her arsehole?” 
Charlie was agreeing with everything.  Suddenly I found myself standing naked beside their bed. Charlies’ eyes were closed but Connie saw me.  “And what would you do if she were here right now?” she asked.
“I would bend her over double and fuck my cock so far up her cunt that it would come out of her mouth!
“Well” Connie said “She is right here”.
Charlie opened his eyes and looked me square in the eye’s “Oh fuck” he said “I am cumming….” And cum he did by the look of it as Connie's eyes rolled back in her head.  “Oh fuck fuck fuck” he said and he reached out with his hand and cupped my cunt then flicked my clit with his finger.
Connie eased up off his fat cock which made a plop as it flopped out of her pussy. 
I looked at it laying there on his tummy dripping wet and shiny. 
“Here” Connie said as she looked at me “Can you give me a hand to clean him up?”
As I went to go down on him, he somehow lifted and maneuvered me so that I was laying on him in a 69 position.  I felt him pull my pussy wide open as he started licking me.  I set to work on his fat floppy cock.  I could taste his spunk and Connie's pussy juice all mixed together.  It was divine.
Connie came down to help me.  After a few minutes we could tell that there was no way to revive his flagging man hood.  Connie had drained all the life out of it. 
Charlies tongue soon had me cumming on his face then the moment was over.
I slipped off of him and stood beside their bed.  Connie slid up the bed and lay beside him.  Charlie smiled at me and said “Soon” then blew me a kiss. 

We had crossed a few barriers and opened up some doors for sure.   Goodness knows where this is going to end.  I can’t wait to tell Greg all about it.

With that I laid back and fell asleep with those delicious thoughts running through my head.
