I was walking to my desk this morning and she was already sitting at hers, next to mine. Desks touching side by side, her seat not more than 3 feet from my own.
I sat down and said "morning all".
Every one replied back except her, just a kind of grunt. She's really not a morning person. She's 5 foot nothing, long black hair, fairly tanned skin. She has a stunning body. Not thin or skinny, but in shape.
We get on, we laugh and joke as I do with all my colleagues, but there's nothing flirtatious between us. Of course I'm physically attracted to her, but that's it. To me she's just a colleague. Our paths would not cross outside of work, and although she's 20, 17 years younger than I am, she acts younger, like a stroppy teenager and with a 'world owes me everything' kind of attitude.
Today she was wearing her usual tight long sleeved black top, that shows off the roundness of her boobs. They're not big, they're not small, they just look like perfect handfuls. She had one of her short, tight skirts on. This is what she wears every day, only instead of her usual black tights, today she had her legs bare. Something I haven't seen her do before.
Whenever she gets up from her desk, she'll turn in my direction and then stands up. I never pay much attention when she does but today was different. I couldn't help but try to see a bit whenever she stood up.
The day went on as uneventful as any other day does in this job and then the end of the day arrived. People were leaving and I was wrapping up my work for the day, as was she by the looks of it.
She turned to me and said "they've finished renovating the floor upstairs, have you seen it? It's like ours but completely empty. It's so weird. No reception area, no false walls, just completely open."
I replied "cool, I'll pop up and have a look on my way out in a minute."
She said "come on, lets go up now, I'll show you".
So we locked our laptops and went upstairs. Our building has the main reception and entrance at the front, but with the car park being at the rear we use the fire exit which leads straight to the car park. We went through the doors at the rear of our office and up the stairs to the top floor.
At the top of the stairs is one door which when you go through has a shower room/toilet on the left then double doors going into the newly renovated office space. I looked through the window that runs the full length of the locked door. "It looks so weird without anyone or anything in there, it's huge" I said.
All of a suddenly I felt her grab my left hand and drag me. As she did, her other hand grabbed the door handle to the shower room and opened it as we stumbled towards through the doorway.
"wha..." I tried to speak as she kissed me. I heard her lock the door behind her.
Still kissing me, her tongue starting to wrestle with mine, she ran one of her hands down from my chest to my cock and pressed her palm against it through my trousers. I started tracing my fingers around one of her tits before cupping it, but still not really sure what was going on. This was a complete surprise to me.
She continued to rub my now growing bulge through my trousers as she started moving round so her back was no longer against the door but mine was. She stopped, took a step back, pulled her top over her head and reached behind to unzip her skirt. She gave a slight wiggle of her hips and let it fall to the floor. She wasn't wearing any underwear.
