Before Ms Matthews could say anything, Jennifer simply grabbed her magic spray bottle, packed her bag, and left the classroom; leaving the 15-Headed Teacher to deal with her new and extremely erotic body.
As she left the science class and made her way to her History Class, Jen saw Principal Anabelle Higham walking the halls. The 40 Year Old Raven-Haired Woman had a reputation in the school for being a real... well.... bitch. It was well documented that she was super strict on Uniforms and severely punished anyone who was wearing the wrong uniform with a Detention Notice. Not only that, but Higham loved to patrol her school and give stern warnings to anyone who she thought would cause trouble; regardless whether or not they had done something in the past.
As Principal Higham was doing her usual rounds of inspecting people, giving detention slips for wrong uniform, and generally being a dick to people; Jen snuck up on her and prepared her bottle of transformative spray. Spraying just a touch of water onto the principals hand without her really noticing, Higham suddenly started spitting some white stuff from her mouth. Her neck also seemed to get longer, and her breasts seemed to get.... larger and rounder.
As her neck elongated, it suddenly gained more veins all around it. Then a weird fold of skin started forming at the base of Higham's chin that slowly started to get more prominent.
That's when it finally occured to Jen what was happening; Principal Higham was turning into a literal dickhead.
The final stages of the Principal's transformation caused her to completely lose her hair and her facial features. Pretty quickly, her face became skin coloured with a slit down the middle. After a few more moments.... Higham now had a penis for a head.
Weirdly though, Principal Higham was still able to talk to all her students and seemingly could still see where she was going. It soon became obvious to Jen that the principal was now actually talking out of her Vagina.
