Fantasy or Wish? I can't tell anymore

Arms covered in tattoos
Blue eyes
Older man
Little rough around the edges
Man of many trades

A co-worker... Well my manager
A married man
And I, single...
Well in a relationship

I do not dare
Yet I can't help
But fantasize
The office at work to ourselves.
Clothes partially off
Him holding my back
Just to support my weight
While fucking me deeply
With his throbbing
Big
Red
Cock.          

Am I insane?
Or just human
To touch myself
At the thought of Cheating

One day Rob
Just keep winking
And smiling
Maybe I'll suck your cock
Maybe I'll start riding it
I know I can't have it,
But you know you want it too
Even just for one night

I swear I won't tell.
