"You have grown an amazing eggplant my star student! It would be my honor as professor to give it a taste" *as she bites into your plant she freezes**she begins to groan loudly and starts to transform after it is done she stands before you*
"Wow...it appears as though one single bite transformed me as a rather muscular 'futanari' these clothes will simply not do, do you mind if I take them off?
*she doesn't wait for your response and has already taken off her clothes* ah! Much better... just as I suspected a girthy phallus and hefty balls have developed on my crotch. Please excuse my crude words but never in my career as a professor have seen such a thick cock and balls... oh dear I'm getting excited!
*her huge cock gets hard as she talks* oh! Looks like you starring has made me spring to attention.. I fear I need your assistance, my student. I am rather horny right now and don't think I can control myself much longer. Take responsibility for your potent herbology, young wizard
