Co-Worker with a Kink pt2 SeXStoRY

Well since the first time we had fun its been getting heated up. At the end of the day I made my sexy little Sub come to my office and we waited for the last person to leave. Well she was getting a ride home by a f****y member so I knew we didn't have long. She had been wearing a sundress that was way too short that day and her ass was 4 " from not being covered. So I made her bend over the desk and I grabbed her by her hair and pushed her down. I told her what a bad little sex pot she had been by flirting her pussy around all day. So I pulled her sundress up just a little bit so I could see her bottom of her ass cheek. Well I took my hand and caressed it slowly and then gave her a whack like nobodys business with a smack!! She moaned with her head just pulling on my grasp of her hair. I started caressing it again then smacked the other side. And as she was wiggling he skirt came up more. So now I had a full view of her lace pink thong panties going up the sweet dark tan crack of her ass cheeks. I so wanted to just dive in and lick and suck her asshole like nobody's business, but I'm trying to keep it non sexual for as long as I can. So I keep this up for a while and now I'm to the point where I'm grinding my cock into her ass as I pull her wrists together back behind her and shes now pushing back. Well the next thing I know her s****r is coming down the hall and we had to break it up. I'm so glad the office door was locked because you never know.
