The bell tolls for thee...

BRRRIIIIIIIIING

You sigh in relief and whimper in frustration as the bell rings and class is dismissed. You are conflicted...on the one hand, you won't get fucked by a whole class and turned into a slutty succubus...on the other hand, you won't get fucked by a whole class and turned into a slutty succubus. But maybe, just maybe, you can convince the teacher to help you change back instead of expelling you.

"Well class, that's the bell, which means you all need to head to your next class..." Professor Puissan drones on as the class stifles their grunts of frustration. "Is what I would say if we didn't have a slutty cunt boi to fuck until she goes full succubus. So line up, fuck the boi out of her as fast and hard as you can and I'll hand you a note for your next class."

It looks like you are about to be thoroughly and irrevocably fucked after all, but on the bright side, at least you will be thoroughly fucked. Any doubts or regrets melt along with your mind the moment a stud student lifts your tail and unceremoniously plows his thick cock into your tight cunt. Your last scraps of manhood are washed away on your drooling tongue, dripping tail, and gushing gash. There isn't time between your savage, soul searing orgasms to worry about consequences or shame. All that matters is milking the incubus incredible cock for his creamy essence...

"Fuuuck...NNH slow...AAH down...NNG I'm...GRR gonna...OOOH!" The stud is no match for your bucking hips and hungry hole. You've sucked the seed from his throbbing rod and absorbed it before he even pulls out. You go to your cumatose happy place, blissful and euphoric and dimly aware of another student lining up to fuck your cunt. This one wants has the presence of mind to rub his girthy tailcock against your lips. You swallow it down on pure instinct and brainlessly buck and suck and coax out two creamy cumloads before long...

The third incubus fantasizes about his older sister succubus and you feel your body shift to take on her more petite proportions and punky style. You aren't sure how you know who he is fantasizing about, but looking over your shoulder you realize you can see all of your classmates' filthiest, most forbidden fantasies. You smile knowing you will be transforming into each of them in turn, teasing and tantalizing them, but ultimately tormenting them as you suck the cum from their balls just as they are warming up.

"NNNNGGHHMMMGHHAAAAAH!" His eloquence is lost on you as you go to your empty headed euphoric island as you slurp up his satanic spurts. The next in line practically shoves him aside and seconds later you are shifting into a slutty dryad with pale green skin and a sticky sweet flower he can't wait to pollinate. By the time class is over you have been teachers, mommies, pornstars, and creatures of every stripe. You have no idea how much cum you have absorbed by the time the last student is finished filling you up, but it is definitely more than enough to complete your transformation into a slutty, semen starved succubus.

Professor Puissan looks down at you, your new permanent proportions even more preternaturally pornographic than his initial fantasy. You are half awake, dreamily hearing him say almost proudly, "You are certainly a failure as an incubus, but I think you have a bright future as a succubus. I am going to recommend you be transferred to Hela's University for Women. But first...you owe your teacher his sweet, sticky treat too..."

The professor lifts you into a kiss and before you know it you are sucking on his tongue, bouncing on his cock, and jerking his tail off with your tight asscunt. He tries his best, but he only manages to hold out twice as long as his quickfire pupils. He explodes inside all three holes at once with a groan of frustration and a sigh of admiration.

This wasn't exactly what you planned when you arrived, but you have to admit, you make an exceptional slut. Maybe Hela U is the school for you after all. Who knows, you might graduate Manga Cum Onme...
