Night security surprise

It began as a normal night shift in a large office block in the city centre.
I conducted my initial patrols and returned to the reception desk to monitor cctv and have a coffee.

It was 1130pm and I heard a knock at the front doors.
As I went to check it turned out it was one of the team leaders from the legal department, one who always bought me in a coffee when I was on day shifts.

"Hi Laura, is everything ok?"
"Hiya Mark, I think I've left my keys in my office, can you escort me up?."

I let her in, and went up to the 6th floor in the lift with her.
She was telling me she had been out with some of the girls for a meal and when she went to get her car she realised she hadn't got her keys.

We arrived at her office and I unlocked the door.

She started to look around her desk, as I looked under the desk in case she had dropped them.
As I glanced up from under the desk I could see up her short skirt, and her sexy stockings.

She walked around the desk and I heard her say, " Are you looking up my skirt?"

I was embarrassed, and apologised but told her she had nice legs.

I was still on the floor on my knees looking for the keys as she slowly squatted down in front of me.

"I've got no knickers on if you want a closer look"

She parted her legs, and pulled up her skirt showing me what was on show.

"Are you sure you should be doing this, I mean it's very nice but......"

Before I could continue she placed her lips on mine and started to slide her hand up my leg teasing my groin area.

"I've always wanted you, you are a sexy man. Nobody needs to know, just you and me."

We carried on kissing sensually, and I started to undo her blouse exposing a beautiful pair of tits, she undid my belt and trousers, and grabbed hold of my cock.

I took off my shirt as she was laid down on the floor inviting me on top of her.
We kissed passionately, our hands all over each other.

"Put your cock inside me, I wanna feel you inside me, " she begged.

I slid my cock in her wet pussy and started to pump away as she began to moan with delight.

We soon changed position as she told me she always wanted to be taken from behind over her desk.

So I bent her over the desk and thrust my cock inside her.

She was screaming with delight. She told me she was cumming and her body shuddered and she came.

I turned her over on the desk, pulled her towards me and fucked her on the desk, kissing her, grabbing her breasts.
She came again.

She sat up and took my cock in her mouth, sucked me off until I came inside her mouth, my cum juice dripping out of her mouth she, scooped it up with her fingers and licked it off.

We sat a few minutes on the floor, she told me she had not forgot her keys, she just wanted me so much.

She started to kiss me again, and we had sex again, it became a regular thing when I was on night shift.
We would have passionate sex in many different areas of the building.
