The Worst HR Lady

We have a women that works for my company going site to site that is a defacto HR lady. She's family of the owner apparently. She has a filthy mouth, not only for young woman but even for a oil and gas worker. She isn't hard to look at either. About 30, a little skinny, blonde, pale skin, decent tits.
I'm at the tail gate of my truck doing tool calibration and she was there just bullshitting, cursing like a sailor. I don't even remember her comment but my reply was, "yeah, you can suck my cock if you want me to do that." She simply said, "okay." My head jerked around to look at her and she had that I'm ready to be fucked look on her face. On these sites there are cameras but they mostly face the perimeter, so right there I had her against my dirty work truck fucking her raw. Pants around her ankles shirt pulled over her tits and fucking her hard. Slamming my big sweaty cock into her bare pussy as hard as I could. She finished me by sucking me off and swallowing every last drop.
I couldn't help but think, how many of the guys I work with have fucked this dirty little whore. She didn't even give a fuck that I was nasty dirty and sweaty she was into all of it. This was end of the 103 degree work day cock sucking.
Fuck if my boss ever finds out, hopefully my wife never finds out and hopefully I can get some of her filthy pussy soon.
