You accept after some persuasion

"Consider it Miss Finch." He removes his finger from your mouth and a trail of saliva stretches until it breaks and falls between your breasts. You flash a sexy smile at the professor while letting go of his cock.

Your hands find themselves wiping up both of your tits as they have accumulated a generous amount of the professor's spunk on them. Quickly you lick and swallow the mess, closing our eyes in the process hoping to fool him. After several repetitions pretty soon your body looks impressively clean for all it's been through.

Frankenstein folds his arms, amused by your behavior. "Simply remarkable..." he whispers.

You take a deep breath and get up in a relaxed manner. Spotting a gigantic mirror not too far away you slowly walk towards it, swaying your curvy hips with purpose.

The professor says "What are you... Ah yes, even you deserve to observe what you have become."

Standing 5 feet from the mirror you get a clear view of the new Heather Finch, and you are struck with awe from the radical changes that have occurred. You don't pay much attention to the professor until he eventually stands right next to you. Staring like the pervert he is, it's as if he is seeing your body for the first time. He places one hand on your shoulder and uses the other to point at your reflection.

"Behold, Miss Finch. You are now the epitome of perfection." he laughs. "I must say I'm pleased with how you're taking this so far. How about it? Would you become my assistant? A seemingly infinite amount of benefits shall come if you accept my dear."

Your eyebrows furrow in confusion as you continue to stare into the mirror, into your aqua blue eyes. You've come all this way, braving through numerous dangers. Thanks to luck and skill, you've somehow come out in one piece... A gorgeous piece to say the least. Your training has brought you to this critical moment. Questions start pouring in one after another.

Why are you standing still? Why aren't you taking advantage of the predicament that you've gotten yourself into? Dr. Frankenstein can be taken out here and now; you can probably kill him before the collar gets you! Sure, afterwards if you succeed you'd probably have to deal with Miss Meadows and maybe a few other guards, but it's not impossible right? How big is the doctor's army anyway? Are you actually going to say yes? Where is your moral compass, your sense of righteousness? For goodness sake, you are the role model of every girl at Paisley!

Frankenstein interrupts your thinking session. "Hmm. It's quite obvious that nothing but doubt is flooding your pretty head. Now close your eyes. I promise that no funny tricks shall be played."

You are **** to trust him but you do, shutting your eyes. You brace yourself, not knowing what he might do to you in your nude state.

He is standing behind you now as you feel his body heat. The professor strokes your beautiful medium length blonde hair that falls down way past your shoulders.

Leaning forward he whispers seductively.

"I understand that given the standard moronic scenario, as the goody two-shoes you would wipe the offer off the table effortlessly without a second thought and I'd have to **** you or return to my original plan. This isn't the case though isn't it, Miss Finch... You may have put on a show for me earlier, and I applaud you for that. I believe that's it's safe to say though that you truly desire this deep down. You are the smartest girl at Paisley after all! The only competent one unlike all the other dumb bratty students. Believe me when I say this. As my assistant, the power you will accumulate rapidly will be almost intoxicating. With you by my side, our enemies
will be decimated. You may eventually even lead my invincible army against the enemy. Yes I know about that sibling rivalry you have with your sister. Can't you imagine the look of jealousy and contempt on her rancid face as you triumph over your inferior counterpart? Imagine all this for a minute. I will too."

You start to dream about all the wonderful things the man had just said, feeling warm all over. Screw the others who have been holding you back for all these years! You're way better than those sluts. Being Dr. Frankenstein's sexy buxom babe actually sounds... Pretty kinky! A sense of arousal washes over you as you wonder what you'd wear as his vixen.

Opening your eyes you slowly snap out of your trance, feeling like a different girl. No not just a girl, but a determined woman that knows what she needs.
All this power, this glory is within your grasp, and you're not going to be an idiot by throwing it away. The innocent face of Heather Finch now has a wicked
grin she's never made before. The old Heather has been reborn into something that Abby and even the Headmistress could only dream of being.

Now it's your turn to interrupt the doctor's thoughts and give him the right answer. You sidestep so you can see him completely. His eyes are closed and looks like he's still swimming in that fantasy of his... Wait, is the horny man drooling? "Ohhhhhhh professor," you begin to say ever so sweetly, "Looks like I'll have to take you up on your scrumptious offer. You have my absolute loyalty."

Dr. Frankenstein opens his eyes, beaming proudly as he licks his lips. His tone of voice now shifts to a more malevolent one. "Clever girl, just as I thought. To think, I almost made the stupidest decision of my life by forcing myself to be you. Only fools would waste a specimen like you. Well it's good that it has come to this. Welcome aboard... Assistant Finch."
