Yes, watch.

Dan kept pounding away at Gina, oblivious to my presence.
Gina was however well aware I was watching, and continued playing with her breasts while staring at me. As I stroked my cock she opened her mouth and with her free hand pretended she was stroking my dick as her tongue swirled around in her mouth. The thought of feeding Gina my cock was too much for me and I lost my load right there, shooting onto Gina's desk. The sudden rush of orgasm faded quickly and suddenly filled with fear, I stuffed my cock back into my pants, zipped up, and fled the scene. I used the stairs rather than wait for the lift and raced to my car before taking a moment to relax.

Shit, I just seen my boss fucking our receptionist... is she even legal? I wasn't sure.

I started my car and drove home, all the while the events of the last few minutes playing on my mind. What would I do with the knowledge? Dan could be in trouble... I could **** him, certainly if she was under-age, but even if she wasn't he'd still not want his wife finding out. That could be risky for me though...

By the time I arrived home I'd calmed down and decided to not say anything, at least for awhile. I pulled into the garage and went inside where my wife was just finishing dinner. "You could have called you know, I gave up waiting and just decided to finish dinner. If you'd been any later yours would have been cold." Some welcome home...
"Hi honey, I'm home," I replied sarcastically.
"Sorry, I just wish you'd call when you're going to be late"
"Okay, I'll try to remember in future," I replied.
"So, why were you late today anyway?"
