You tell her you can give her a $500 bonus for her pussy or $1,000 for her ass

"Well, I could give you a $500 bonus if you bend over and let me fuck your pussy right now," you say as you grab Samantha by the wrist and spin her around.

"But that's not enough!" Samantha says desperately.

"Or..." you continue grabbing her butt cheeks through her skirt, "You could earn yourself a $1,000 by giving your ass to me." You say it like you're doing her a favor.

Samantha's lip quivers at the thought of you fucking her ass. She's never had anything more than a finger up her backdoor before. And you have a porn star cock that she struggled to fit into her mouth!

"But Mr. Madison, I need the $1,000, but your cock is too big for... that..." Samantha says nervously.

"How about this," you say as you take out your wallet. "Since I'm such a nice boss, here's $20. You go run an errand to CVS and go buy yourself a big bottle of lube. Maybe one of those warming or tingling ones. And then you can slather it all over my big cock before you do what needs to be done."

Samantha silently takes the $20 bill from you. She has a look of horror on her face.

"Make sure you get a big bottle in case we end up doing this again," you say, teasing her.
