The professor removed her slacks, walked over to the front of her desk, and bent over it. "There is no way you could ever get me to do this. I'm doing this of my on volition."

"What if it was something way, way out there like...oh, I don't know - you begging me to spank you then having me a actually do it?"

"Look, this is tiring, but I'll prove it to you. Everything I do is because I want it done. Now, please, please spank me!"

"Really?"

"Please spank me! I need it. Please! Do it!"

"OK, if you insist." Peter started spanking Professor Gonzalez-Mercer's plump but firm ass, clad in dark blue cotton panties. He kept it up. "And if this turns you on and makes your sexually aroused."

"Uh...oh...yes, it's because it just does. You have nothing to do with it."

Peter kept spanking her ass until his hand got tired, and the professor was panting, and her crotch was growing wet. "And if you let me pull these panties down and fuck you?"
