I want you to imagine bending me over this desk into the position you're in now and fucking me hard (pretend you actually have a usable cock). Can you see me moaning and convulsing with every thump, as the papers and pens on the desk fly everywhere?
Now I want you to pretend you're in that situation...except you're the girl getting fucked.
Go on, I want to hear you shaking and screaming. If you're convincing, I'll let you play with yourself a little more.
