My name is Mal, when I was in my late teens, I was seduced by a couple whom I used to house sit for. Their names are Reg and Sally. Reg was very cheeky and saucy.  Sally was a very fit lady, late 30’s. She would often walk around in a lycra leotard and spent ages in their gym keeping in shape. 
They had a beautiful home with indoor heated swimming pool and sauna. 
During these house-sitting times I had come upon their stash of homemade porn movies featuring both Reg and Sally plus some other people.  (as documented in my previous adventure “House sitting opens many doors”)
One time that I was due to house sit for them they had a change of plan and didn’t need me but said that I could stay over for the weekend anyway which is when I was seduced by them.
It might sound a bit screwed up but the three of us have been lovers ever since. Often, I would tell my parents that I was house sitting and they would say something like “again?  They sure have a lot of holidays” when the reality was that they weren’t going away at all so I would spend lots of time with them.

So, 6 months or so after my seduction my twenty first birthday was coming up, Reg and Sally said that they wanted to do something special for me.
I told my parents that I would be house sitting for them the weekend after my birthday. Reg picked me up as usual early evening.  On the way over to his house he kept smiling at me, I asked him what was planned but he wouldn’t answer, he just smiled and stroked his hand up and down my leg.
When we arrived Sally came out to greet us and gave me a kiss and hug.   She remarked how sporty I looked in my shorts, sports vest and trainers. Sally was in her trade mark leotard.   We made our way into the house.

“Well,” Sally said “we are going to give to you a birthday pressy like no other but it isn’t here yet”
I tried to coax out of her what it may be but she was adamant and wouldn’t tell me, not even a hint. We were sitting in their beautiful kitchen waiting for the coffee to percolate. Reg had slid his hand up the inside of my thigh and was about to slip his fingers inside my briefs when Sally told him to stop “It’ll ruin the surprise.” She said. 
Reg reluctantly removed his hand which left me a little disappointed because I could already see that his man cock was swelling in his shorts.  I just wanted to rip his shorts off and lick his fat cock.  I had become a bit of a cock whore, to put it bluntly, these last few months.
At about 8pm Sally ordered up a Pizza which took us through to 9ish.  Reg asked Sally if she was going to get me ready for my birthday pressy.
‘Get me ready for my birthday pressy’ I thought.

Sally got up and taking my hand she led me to the master bedroom.  I used their en-suite for a shower.  Sally patted me dry with a fluffy towel.
Meanwhile she had laid out on the bed some very erotic lingerie.  It was powder blue, silky and I couldn’t wait to get it on. I am sure that somewhere back in my gene pool there would have been an exotic Asian which gave me my slightly tanned skin.
She said that she was going to make me into a real woman.  Normally I am a sporty trainers kinda outdoor girl and I have never had anything this fancy.  We heard a noise in the hall outside and Sally shouted out “Reg, go away.  You’ll see her soon enough.”
We heard a sigh from just beyond the bedroom door.

First off Sally had me slip on some lacy stockings.  Even though I am quite leggy they came well up on my thigh plus, they were hold-ups which felt great.  Then came the silk panties which felt good against my skin.  Next was the bra.  I am not very well endowed in the upstairs department, even so she had got my size dead right.  The contrast of powder blue lingerie was set off by my slightly tanned skin.  Then she slipped me into a clingy red silk mini dress that came down to the band on my holdup stockings.   She said that 5” stilettos would go perfect with my outfit but because I had never worn high heels before it would be best to leave them off.   I looked at myself in the full-length mirror. 
“Dressed to kill” Sally said.  “Just one thing more, how about a little make up?”
I have never been one to wear makeup so this was all new to me.  Sally went to work and in 10 minutes I was wondering where this sex kitten had come from as looked at myself in the mirror. 
“Let’s see what Reg thinks shall we?” she said as she led me by the hand to the front room where Reg was watching porn and stroking his man cock.
“Put that away Reg” she said to him “and tell me what you think.”
Reg flicked the TV off and we could tell what he thought by saliva dribbling down his chin.   
Looking around the room I could see that the lights had been dimmed and there were 3 cameras set up in various places as I took my seat in the middle of the settee which seemed to be the focal point of the cameras.

We had a couple of drinks, Sally put on some soft music for atmosphere.  She was still wearing her leotard and Reg in his shorts.  I was still wondering what my surprise would be and to be frank, what with the music and the drinks I was feeling very sexy.
At 11pm the doorbell went.  “Ah” said Reg, “that will be your birthday pressy.”
He answered the door and then led an older man in who was carrying a suitcase and a holdall. The guy nodded to Sally so I guess they knew each other.  The guy must have been 50 if he was a day.  He was slightly tubby, about the same 5’6” height as me, thinning hair.  Not much to look at but what he did have was a huge smile.  Reg introduced us “This is Graham” he said indicating the guy “and this is Mal, the birthday girl” indicating me. 
Graham put down his case and holdall and came over, I thought, to shake my hand and say hi but how wrong I was.  He shook my hand sure enough and lent in for one of those cheek-to-cheek kisses only he didn’t, he kissed me full on the lips.  I pulled back a little in surprise and he gave me that huge grin again.   Then he went over to Sally and gave her a huge hug and a very passionate kiss by the looks of it.  She didn’t bat an eye.
“Right” said Reg, “Graham here is a photographer and he wants to take some professional photos of you for a portfolio.”
“A portfolio for what?” I asked
“OK” Sally came over and put her arm around me “Well, we showed Graham here some of the videos that we have shot of you and he thinks that he may be able to get you some work modelling”.
I was momentarily mortified that they had shown some  if the movies of us making out together to somebody else, on the other hand, I found it very exciting knowing that somebody else had seen me in very compromising scenarios.
“Modelling what?” I asked.
“Lingerie” Sally said “Let’s face it you have a great model’s figure, slim and athletic.  You have beautiful skin and look how hot you look right now” she paused “But it is entirely up to you, at the very worst you will have some great photographs and at best you may realise that you are a natural”.
In the meantime Graham was setting up his gear so I guess that it was a forgone conclusion that I was willing, which I was..
“Ok” I said “I am up for it”.
Another drink and then I was standing in front of the forest mural at the end of their front room.
“Righteo” Graham said “Now just keep your eye’s looking directly into the lens unless I say otherwise, OK”
“Sure”
Soon he was clicking away.
“Look this way” …” Look that way” ...” Pout” …” Make love to the camera” …” Imagine the camera is your lover” …the instructions were coming think and fast.
“Bend over slightly” …” Pull your dress up a little to show your stockings” 
I obeyed every command and I was really starting to get into it.  I was feeling sexier and sexier by the second.
“Higher…Higher” he said indicating my dress.
I pulled the hem up to my crutch, then a little higher.  I guessed that he could see my knickers but I didn’t care.  I was making love to his camera.
Off to my right I could see Reg and Sally but I couldn’t see what they were doing.
“Lose the dress” Graham said “Take it off”.
Sally was there in a heartbeat and my dress was gone but still Graham kept clicking away.   I was moving and gyrating like I had seen dancers do.  Somewhere I heard Reg call out that I looked “fucking hot”.
Goodness knows when or where I lost my bra and knickers.  Now I just had my stocking on.
“Fucking brilliant” Graham kept repeating. 
This was getting out of hand but I didn’t care.  I felt like I was oozing sex. 
Graham called time out for a break.  I could see in the dim lights that his head was covered in sweat.  I felt a bit sorry for him. Reg handed round some more drinks.  I was naked but not embarrassed.  I noticed that Reg and Sally were also both naked.  Regs cock was sticking straight out from just below his belly.  So tantalizing close but Graham wasn’t finished with me yet. 
Sally went over to Graham and kissed him with passion while reg stripped him off.  When they broke their kiss, we were all naked.  Graham just flashed that huge grin of his.

“Ok” Graham said “are you ready to start again?” and off he went clicking again.  His cock and balls looked heavy.  Subconsciously I made it my quest to give him an erection.  I got into as provocative poses as I could muster.  Then I was using my hands, caressing my body, my breasts, my pussy.  Graham’s cock was responding to my seduction of his camera.  I moved over to the settee and laid back in the middle of it.  Opening my legs wide.  Graham came in for close up shots, so close I could feel his breath on my pussy.  Looking down I could barely see his head between my legs.  Still, he clicked away.
Reg was just off to my left, I beckoned him over and grabbed hold of his man cock.  He let out a groan, Graham looked up then forgot about his camera and was busy eating my pussy.   

The photo shoot had descended into a mini orgy.  Sally came over and took over sucking Regs cock.  Graham came up for air and looked at me with that stupid grin that guys get when they know that they have passed first base.  He moved over a little and I slid down onto the floor, legs spread wide and then he was on top of me.  As his lips met mine, I felt his cock slid into me.  I remember thinking that I hadn’t even seen his cock erect and here it was buried inside of me.   He was a good kisser and a good fucker.  In and out he went.  Each time that he went in I felt the weight of his tubby tummy on mine and it felt good. 
I reached my arms around his neck and pulled his face to mine and kissed him, he didn’t lose momentum.  He made my pussy wetter and wetter until I felt him tense up and then he was cumming inside of me.  I sighed; he sighed.  After a short while he rolled off of me and lay there panting. 
I wondered where Reg and Sally were, it didn’t take long for Reg to make his presence known between my legs, lapping at my pussy.  Then he slid up my body and kissed me.  I could taste Grahams cum and my love juice on his lips.  His cock slid so very easily into me wet pussy.  I reached down and held his buttocks, pulling him in deeper.  It only took a few thrusts before he was giving me what Graham had given me a few moments ago.  As he rolled off of me, I saw Sally, she had been videoing the whole thing.  Another one for the archives I thought.

It took us all a while to regain our breath and come back down from the sexual high that we had just embraced.  I still hadn’t seen Graham’s cock hard and I said as much. 
“Well, we can do something about that right now” Sally said. He was sitting on the settee, she knelt in front of him and started playing with his cock.  She beckoned me over and between us kissing, sucking and licking we soon had Graham hard.  He wasn’t as big as Reg but he was as hard as granite. 
“This one’s mine” Sally said then straddling him she rode his cock.  Her tits were in his face and he was loving it.
Reg was on video duty taking in the whole scene but I didn’t care, I wanted Regs fat cock again and I wanted it now.  He was already semi hard so not much work for me to do.  I got on all fours in front of him.  I licked his cock, stuck my tongue in the hole at the end.  After a few wanks with my hand I felt him harden so I turned around presenting him with my rear end.  He soon got the message; I felt the tip of his cock ready to penetrate me.  Before I could say a word, he was sliding his fat man cock into me.  I had to do most of the work because he was trying to film Sally and Graham. 

This is how we finished up at 4 am.  All naked, sweaty and truly fucked. 

I have seen Graham a few times since this evening.   I don’t know what happened to the photos and I never did get a portfolio but then again, I think that that was just a ruse.  Even so, I wouldn’t be surprised to one day see them on some porn site.  I am a little older now so I doubt that anybody would recognize me.
I got to keep the lingerie and dress.
I still have a copy of the videos that Sally and Reg shot that night and the night of my seduction. I have shown them to my partner who thinks that they are “Down right fucking dirty” to quote him.  Judging by the speed that his cock gets hard when watching them I would say that he approves.
