Now I want you to get undressed, and then put on a pair of the softest, silkiest panties you have... and a pair of thigh-high stockings.
Squeeze into those stockings, Prof. I want you to look pretty for me. After all, I own your sexy ass now.
Rub your little... clit... through your panties. Think about where we are and how any moment someone could bust in here and see you. And think what I could do to you... if everyone found out you were a little sissy, you couldn't hold any authority at all in this classroom.
Everyone would just laugh at you... laugh at you and call you "Professor Pantyboy." Haha... I like that! Your new name is Professor Pantyboy!
