Like most good things in life, they have to end, and working at the centre was no different.
It had barely felt like the season had got going, before we were talking about the end of it, and pretty quickly it was.
The final day of the working year soon came around, and it was almost time for us to head home again, but not before, our big end of season party of course.
Like usual, the evening started with a nice big three course meal in the main dining room, followed by some speeches from the manger and senior instructors.
Then it was party time, and a local DJ started to play all the latest dance and pop tunes, while disco lights flashed around the room, and free drinks, courtesy of the company, were quickly handed out.
We were all soon having the time of our lives, drinking, dancing, and just enjoying the last night together.
However, after a few hours of humiliating myself on the dance floor, I needed a sit down, so I flopped into one of the seats at a table, around the side of the room, and relaxed a moment.
As I sat there with a drink, happily watching everyone else still making fools of themselves, Kerry, one of the nicest senior instructors in the place, then strolled towards me.
She was a short, chubby young woman, with long brunette hair, and wore black rimmed glasses, and that evening she had on a knee length red dress and matching high heels.
I have to admit she did look very pretty, especially as her dress barely held in her perky breasts, and as she stepped closer, she said with a smile "Hey Steve. You okay?"
"Yeah. Just chilling for a minute!" I replied happily back.
"Mind if I chill with you?" she then asked with a smile.
"Sure!" I replied happily back, because she was a good friend, and I certainly wasn't going to say no to her.
Kerry then promptly sat down in my lap, wrapped and arm around my shoulders, and then smiled at me.
It was a little surprising and it wasn't, because Kerry had a long-time boyfriend who was a senior instructor at the centre, so she probably shouldn't have been this flirtatious with me in public, but, we also had secretly had sex, with her boyfriend's permission, so it wasn't totally unexpected.
"So, I was thinking..." she then said cheerily, before pausing for a moment.
I stared curiously back at her, wondering what she was going to say, before she leant in, and whispered in my ear "About getting your cock out right here, and riding it!"
She then sat up again with a grin, before asking "So, what do you think?"
We were sat in the middle of a crowded hall, surrounded by our fellow colleagues, friends and bosses, and her boyfriend who was dancing only few meters away from us, and she wanted to know, if it was a good idea, if we had sex right there in front of them.
Well, it might have been the alcohol talking, or the fact it was the last night of the season, but after a moment, I smiled back at her, and replied "Okay!"
"Yeah?" she asked excitedly again.
"Yeah!" I replied eagerly.
Kerry then grinned, before she started to move her plump little arse in my lap.
Steadily, to the rhythm of the music playing, ground her soft warm cheeks, against my bulge, and pretty quickly, I began to get aroused.
As she continued to rub her butt against my crotch, my cock grew harder and harder in my trousers, and after just a minute or more, I had full on erection straining against my pants.
Kerry could definitely feel this through her dress, because she grinned excitedly at me, and then, after grinding herself against me a little more, she slid a hand down under herself, and began discreetly undoing my trousers.
It wasn't easy, trying to release my firm dick, while hopefully no one noticed, but eventually, after a little struggle, Kerry managed it, and as soon as my stiff length popped up against her butt, she moved herself into position.
Briefly standing up for a moment, she casually lifted the back of her dress up, and I got quick flash of her pale bare round cheeks, because she wasn't wearing any underwear, before she then promptly sat back down, straight onto my rigid member.
Her warm moist pussy found my cock instantly, and in one swift motion, slid straight down it, before we both let out a stifled moan of pleasure.
Kerry was now fully impaled on my dick, and for a moment she just sat on top of me, enjoying the feeling of it, deep in her cunt.
Then she started to grind herself against it, rubbing her wet little pussy around in eager circles, as the music continued to play, and our friends and colleagues danced in front of us completely oblivious.
I couldn't believe this was happening, I had fucked Kerry a couple of times before, but in private, behind closed doors, and certainly not like this, but, this was exciting, and I certainly wasn't going to stop it now, so I just sat back and enjoyed it, as this hot young woman did her thing.
Keenly Kerry continued grinding her wet little cunt against my stiff length, and as she did, we both moaned softly, still trying to be discreet.
Her hot moist hole slid around my member again and again, and as her pussy played with my cock, her soft warm arse cheeks rubbed against my waist, and it felt wonderful.
After a couple more minutes, we started to lose ourselves in our own pleasure, and our movements became a little more visual, but we didn't care, as we continued to fuck.
As we kept going, the music changed from one song to another, and the next one had a faster happier beat, and instinctively, I started to bop to it, pushing my hard cock in and out of Kerry's lovely wet pussy.
Instantly she moaned a little louder, but, because the music was pretty loud too, thankfully no one else heard it.
So, we kept going, and as she ground herself harder onto my firm dick, I thrust back and forth inside of her, and we were really fucking in that crowded room.
For another few minutes we continued to fuck like that, and as the song that was playing switched to the next one, I felt like we could keep doing this all night.
I think Kerry did too, because she eventually leant back against my chest, and said with a groan "Oh Steve! I don't want this night to end!"
"Yeah! It is pretty good!" I replied eagerly back.
We continued to fuck, steadily and discreetly under her pretty little dress, and another couple of minutes swiftly went pass, before she asked "You promise me, we can do this again, next season?"
"Whenever you want?" I replied back eagerly.
Kerry grinned, then lifted her head up towards me, and we kissed.
It was only for a few seconds, because we both knew someone might see us, but it was still nice to be able to do that.
Then after our kiss, Kerry continued to grind herself against me, as I pumped my cock up into her, and quickly, our movements became more ecstatic.
