You almost feel a little bad as you stare at her from your desk, watching her eyes dart up, trying to spot what you did to her-- she gets a glimpse of the new cunt in her periphery, a hint of the new sex organ she has bared to the whole class, and she resists the urge to poke and prod at it. It's clear that, even if they might not think this is normal, it's not worth freaking out about, because... you can do anything. If you wanted to give her a vagina on her head, what's she to do about it?
Darkly amused, you get up from your desk and start to walk over towards her, curiosity getting the better of you. She's a real mess now, isn't she? ...Should you fix her, or make it worse?
Her eyes lock on you as you walk down, but she looks almost neutral about it. She's not in a position to be blatantly ANNOYED with you now is she? Remember-- you can do anything you want.
While the rest of your class keeps taking notes, paying you little mind besides wanting to spectate you the same way anyone would a student getting up from their desk, your teacher stares at you and puts on a small smile as you stop just shy of her, your own eyes staring at her forehead. "Is there something you need?" she asks almost timidly, always keeping up a pleasant face for you... only to let out a startled gasp as you reach a hand into her pants and grip the cock you've given her for a moment. It firms up immediately, a sudden shot of pre wetting her leggings, and she blushes deeply, not saying a word, just staring at you.
"Do I need to need something to come up here...?" you counter, gently rubbing it between your thumb and forefinger as she lets out an aroused whimper, slowly shaking her head. "N-No, of course not, you can... u-um...!" she squeaks, a throb running through her new member, face totally flush with shock and heat.
The curious thing about your powers is that even though everybody accepts what you've done, that doesn't give them any false pretense about it, either. She is fully aware that this is the first time she's ever had a dick, no false notions that she's always had it as a result. You changed their bodies, but not their minds... save for the parts that would protest against this. Despite how surprising it is, it's still just... fine, because you're you, and you can do anything.
You pull your hand out of her pants, leaving her gently panting as you wipe that small amount of cum across her breasts, smiling devilishly at her. "D-- Do you..." she trails, trying to find something fitting of her job to say in response to all this, but when she draws up blanks, she just stops, your ability to do anything winning over anything counter to that.
You click your tongue. Your eyes look up to her forehead again, and you get some ... ideas. After just a bit of thought, you...
