Working at an outdoor centre you meet a lot of people, kids mainly, but also adults, the adults that accompany them.
Now, most of these adults are teachers, so the kids have a familiar face they can turn to if they need to, and most of them don't just come along for the kids, but to have some fun as well.
Anyway, on this particular week, I was working with a great group of children, and their teacher, Mrs Shelton.
Mrs Shelton was in her early forties, and was a tall, blonde, mature woman, who appeared to have a nice slim body, under her stripy blue and white top, and her tight jeans.
She was also very cheerful, friendly, and got involved in all the activities, so it quickly turned into a pretty good week, for all of us.
Anyway, on their last day, on the last night of their stay, as I was putting away the equipment we had been using that evening, Mrs Shelton came strolling up to me, and cheerily said "Steve!"
"Yes, Mrs Shelton?" I replied back, as I stopped and looked over at her.
"I was wondering, if you would like to join me in the lounge, for a drink?" she then asked, with a smile.
Now, the thing you need to know here is, the guest lounge was strictly for guests, our manager Tony had made that clear at the beginning of our employment, and the only time 'we' instructors were allowed in there, was to clean, or if we were invited in, by a guest.
This was because, he saw it as a perfect time to do some P R work for the company, to encourage them to book again and smooth out any minor problems they may have encountered, but weren't willing to make a fuss about.
Anyway, if we did get invited to the lounge, for a drink, he encouraged us to agree to it, as long as we didn't overdo it.
So, with that in mind, I cheerily replied "Okay! I'll meet you in there shortly!"
Mrs Shelton smiled happily, then strolled off to freshen up, and after I had put away everything I needed to, I made my way to the lounge.
Now the guest lounge was at the front of the house, and it was the old living room, that the company had nicely decorated, filled with expensive leather sofas and chairs, a television, and had an honour bar, at the far end of the room.
That's where Mrs Shelton was sat, at the bar, and now dressed in a pretty pink blouse, a knee length black skirt and a small pair of black heels.
She now looked like a pretty hot MILF, so, I eagerly made my way over to her, and after getting a bottle of beer out of one of the fridges, I sat down beside her, and we started to chat.
As we talked Mrs Shelton drank a glass of wine, and the evening progressed quiet well, talking about her and her groups stay at the centre, before we moved onto other topics, and soon were laughing and joking about many different things.
Anyway, the jokes, the laughter, and the drinking, continued, and the evening went by pretty quickly.
As it did, I couldn't help but notice, despite being almost twenty years older than me, Mrs Shelton was actually still very beautiful, with a happy smiling face, and her long blond hair framing it, and I quickly began to find her, quite attractive.
Anyway, as the late evening turned to night, all the other adults headed off to their rooms, until, Mrs Shelton and I, we're the only ones left in the lounge.
Then as she finished her fourth glass of wine, she asked curiously "Steve. Would you mind coming up to my room? The window is a little sticky, and I... need a little help closing it!"
"Err... sure." I replied, remembering I was still on P R duty, so I was technically there to help, with whatever she needed.
So, I finished my beer quickly, and then Mrs Shelton led me up to her room.
Leaving the lounge, we climbed the main staircase to the second floor, then strolled along the corridor, and once we reached her room, Mrs Shelton unlocked the door, and led me inside.
The room was one of the centre's nicest, with a large double bed up against the far wall, an old, but expensive looking wooden wardrobe and desk across from it, an on suite bathroom through a door beside the bed, and the window, was across the room, and it gave anyone looking out, a nice view out over the nearby fields.
I quickly moved towards the window, as Mrs Shelton closed the door behind her, and then taking hold of the wooden frame, I gave it a good firm jiggle, until it finally closed shut.
"There! All closed!" I said cheerily.
I then turned around, and instantly stopped and stared in disbelief, as Mrs Shelton, stood in front of the door, blocking my exit, in just a black bra and matching knickers, and her heels.
"What do you think?" she asked eagerly, posing proudly for me.
I stared at her slim mature tanned body, with what looked like C - cup boobs under her bra, and her long tanned legs, and after a moment I nervously replied "You... err... look, very pretty!"
"Just pretty?!" she asked back curiously, before she started to stroll towards me, and then asked "Because I thought, I was looking very hot!"
"That would be another way to put it! Uh huh!" I replied, still a little nervous.
Mrs Shelton grinned, as she wrapped her slim arms around my neck, pressed her half naked body up against me, and then asked, inches from my mouth "Would you like to touch my... very hot body?"
"What about... Mr Shelton?!" I asked nervously back.
"Well, he's not here, but if your into that kind of thing, I supposed we could arrange something, for another weekend?!" she replied sarcastically back.
"No. I meant..." I quickly replied, before Mrs Shelton said "I know what you meant. But don't worry about it. He's not here. It's just you... and me!"
She then leant in and kissed me, and after a moment of still looking very stunned by what was happening, I finally began to kiss her back.
Our lips locked together, as our tongues eagerly explored each other's mouths, and as we stood there in the middle of her room, kissing, her slim hands began to roam around my body.
She then found my trousers, and taking hold of them, she quickly unbuttoned them, before pulling down the zip, then let go of them.
My trousers instantly dropped to the floor, and once they were out of the way, she reached down wrapped her soft warm hand around my growing member, and began to stroke me into life.
I immediately moaned softly at her touch, as we continued to kiss, and as she jerked me into life, in her tight grip, she pulled her lips from mine, glanced down at my dick, and then said happily "Oh, goodie! A big one!" before she looked at me and said lustfully "I do love a big one!"
"Okay!" I replied, not sure what else to say to that.
