Try to tell her

“Uh, Ma’am I think you...” You start trying to explain but she seems unwilling to accept your help and cuts you off before you can tell her.

“Quiet Mister Doe or I’ll make a change you won’t be able to fake obliviousness about.... actually that may not be a bad call.” She gets an evil grin as she fiddles with the app more leaving you to ponder why she called you Mister.

You look your body over again but it all seems in order... except... what girl with H-cups goes to school without a bra?... and boxer-briefs... the more you look yourself over the more you realize you’re wearing boys clothing. You may not have been the smartest person alive but deductive reasoning was not one of your weak points. That must have been what she changed. You used to be a boy and now you’re a girl... with massive titties and a giant cock... wait giant cock? Was that always there? It feels normal but the more you try to remember the more things seem to unravel. You’re starting to question who or what is real.

“How about that Mister Doe? Can you ignore that? Hmm? Or should I make you even bigger?” Your professor walks over and pats the shaft of your gargantuan dong like it’s a third leg. It feels good she touches your fat meat pole you feel it start filling with blood. If it’s the size of a leg now it’ll probably be the size of an entire person once it’s hard.

It’s getting harder to think about anything else. The bigger your dick gets the more you fell like fucking something or someone. There happens to be another person present... maybe you can put that stretchy skin she gave herself to use and just shove your cock into her. Besides if she’s changed you into this then that means she wants it too right? Makes sense.
