Just happened in my shop

I'm not that great at writing stories and maybe this should be in a blog instead but I had to write while it was fresh in my mind.

I'm a Maintenance Supervisor in a small apartment complex, hell I'm the only Maintenance thus the title. My shop is next to the mail room and L shaped with the door located at the top of the L and my desk around the corner at the bottom. Because of the location of the desk I rarely lock the door. I was on my laptop watching some videos here on Xhamster not thinking anything about it. I had my pants undone, underwear pulled down and slowly stroking and teasing myself as I watch the video. I was into the video when the door opened and a female voice called my name, before I could get up and pull my pants up she walked around the corner and caught me.
Her name is Mary, she's married with three k**s but she has always seemed extra nice I guess I would say, hell she had her husband deliver some brownies to me she had made for Holloween. Mary always wore a dress and I mean always and I had no idea why but it was my lucky day she was wearing one today.
Without a word she smiled walked over to me, got down on her knees and began sucking my cock, playing with my balls as she did. My hands held her head as she bobbed up and down on me, as I was beginning to tense up and shoot she removed her mouth from me, stood up reached under her dress and pulled her panties off, cute little flowered ones.
Sitting her panties on my desk she then straddled me and I slipped into hot wet pussy like it was made just for my cock. Mary was always so sweet acting but as she rode me some of the language coming from her mouth would have made a sailor blush. It was fast, hard and deep, we both came at the same time and after a few minutes laying on me, Mary got up, put her panties back on, composed herself, leaned over gave me a kiss and said thank you with that smile then walked out of my shop.
I'm at home now and relaxing in my recliner and still wondering if it really happened or not, then I look down at my crouch see the wet spot on my pants and feel the stickiness as her and my juices dry.
