The Frost Witch's Punishment
Luna von Adelheit.
"That's the wrong answer."
Slap.
"Kyaaak!"
Her head lolled weakly to the side. Tousled silver hair. Swollen cheek. But instead of pain, her face was flushed with rapture as she clutched the hem of my pants.

"S-Sorry, Master."
"Say it again."
"I was wrong. This stupid Luna bitch messed up the calculation."
She trembled violently, pressing her lips to the top of my foot.
Luna von Adelheit. Dean of the Magic Department at the Federation's most prestigious Joint Educational Institution. The Frost Witch who strikes terror into the hearts of students. That noble elf professor was now groveling at my feet.
"Luna."
"Y-Yes?!"
"Lie down properly."
At my command, her shoulders jerked upward as if electrified. Luna hurriedly leaned her upper body against the desk and thrust her ass high in the air. Above her snow-white thighs bulged a thickly swollen adult diaper. Soaked through. She'd clearly pissed herself once already. The smell wasn't foul. If anything, it was a fragrant female musk. It should have looked filthy, but...
I unbuckled my belt with practiced ease.
"Khuk, ahk!♡"
I roughly looped it around her nape. A ragged breath escaped her, mingled with a metallic rasp. The agony of strangulation. But an even greater anticipation sent electric thrills racing through her entire body.
"Master, Luna will be good. Please.♡"
"Wait."
"I can't hold it. Give me boobies. Master, please.♡"
She shook her hips desperately. All traces of her lofty intellect were gone. Nothing remained but a beast starved for instinct.
Riiiip!
Tearing off the diaper unleashed a sharp, fishy aroma.
Smack.
My palm crashed down on her wet ass.
"Aaah♡!"
"Count the numbers properly."
"One! Eut♡, one!"
"Louder."
"Twooo! I love you, Master!♡♡ Threeee!"
Luna wailed in ecstasy with every strike. Without soundproofing magic, the guards would have burst in long ago.
I pressed the 'baby bottle' to her lips.
"Here."
"Mm! Chup, mm!♡"
Like a chick orphaned of its mother, Luna suckled greedily. Her slender throat bobbed with every gulp of 'milk.' Tears streamed from the corners of her eyes, wetting the bottle. An expression of utter satisfaction. No sign remained of the elegant professor who had just lectured on advanced magic theory. Only a newborn infant, drunk on bliss.
I'm screwed.
As I stroked her silver hair while she nursed mindlessly, the thought crossed my mind. Graduation was off the table for this lifetime.
