Looking for a fun, long-term story, with a good blend of realistic personalities and porn logic, in a setting with magic, transformations, and mind manipulation.

We play as characters enrolled at a magical college in a world where magic is just another fine art. Your friends or sorority have given you

a dare. Sneak into Professor Grumble's tower, and steal something that proves you did.
You feel confident enough in your ability, but what you weren't expecting was Professor Grumble was a big ol' pervert. You sneak in to the tower, avoiding alarms, and traps, and find a room filled with manacles, crops, X-frames. But what to take? Then a gem catches your eye, you grab it, but as you do you realize too late that it's another trap. The gem is part of a steel butt plug. A plug that begins to float and then pulse blasts of pink energy into you. With every pulse your body changes. Ridiculous bimbo curves, heavily made up and modified face, your outfit reduced to a pink harness, ballet heeled thigh high boots, nipple clamps, arm binder, a translucent blindfold and gag, a small butterfly vibrator pulsing in rhythm with the plug, and finally the pulsating plug entering into you, continuing to pulse, rewiring your mind and desires to match your body and its new purpose.

You know that it is the plug's magic is making you feel these things. That there is nothing natural about what you are feeling or what you have become...but it feels so good. You know you should resist...but you don't want to. So you wait, armbinder at some point becoming affixed to the ceiling. Your mind and body continuing to become molded and primed for your owner, whenever he wakes and discovers your intrusion.

But...

But you weren't the only intruder that night. My friends had put me up to steal from Professor Grumble that night too. I arrived shortly after you, and watched you change. Maybe you knew I was there before, maybe not. Regardless, I don't want to leave you for the woods, unchain you, and take you home.

It turns out the magic isn't done though. When I slide off the hood or blindfold and our eyes lock, your irises shift pink, and the magic imprints us on to each other. All the desire and devotion that had been flooding into you is given form. Me, your Owner. The realization is orgasmic in its own right.
Perhaps there are some changes that effect me, let me know what you'd like regarding that in your reply, but I'm at the very least given some idea of what has just happened, and the responsibility it entails.

So that's the base set up. Who are we? A fantasy setting like this fantasy races are certainly an option, but if you prefer human that's great too. Maybe we know each other? Maybe we're friends or rivals? Let me know what sounds best to you.

Alternatively, maybe you have a different trajectory in mind? Maybe you'd prefer imprinting onto Professor Grumble? Maybe you have other transformative story ideas on a colligate magical campus? Let me know.
