She has the beginning of a plan (sort of)

"Hell yeah! I will convince her to hire me!" she replies with a bright smile.

You wait for the next part of her plan, but she just sits her, looking happy. "And then?" you finally ask.

"And then I'll improvise. Maybe I will find some dirt to dig, or maybe she will invite me to join her in one of her orgies. Hey, maybe she will leave me **** and I will end up bound and gagged while she's taking adventage on me. Hmmm..." She's back in fantasy land and frantic masturbation.

"Uh... Are you sure?" You hesitate. "You may get caught. Or... Find out she's more fun than I am and switch side." You're half joking, but this possibility looks more and more like a plausibility.

She giggles. "Don't you trust me? The only thing that I love more than you is a good challenge, and turning a dominant slut into a submissive **** is more interesting than just have sex with her and a football team. Which I can't promise I won't also do."

That's... slightly reassuring, but not the answer you were hoping for.

"Jeeze, stop brooding and come fuck my cunt, stud, it will brighten your mood. And tell me more about how you picture yourself fucking your sister doggy style on her desk and spanking her pregnant ass!"

And just with that, all your worry disappear for the time being.
