Your prank works better than you could have hoped

As the first light of dawn creeps in through the tall, arched windows of the dormitory, Einamina stirs from her slumber. She stretches languidly, her silken nightgown slipping off her shoulders to reveal the creamy skin beneath. Rising gracefully, she makes her way to her dresser, selecting one of the many pristine bras hanging neatly inside.

As she slides it on and adjusts it beneath her uniform, she feels the fabric against her skin. It is ever so slightly more textured than usual, a faint prickling sensation along the ridges that makes her pause for a moment. She runs her fingers over the cups, frowning slightly as she tries to recall if she had ever felt this particular bra to be quite so rough before.

"Odd," she mutters under her breath, shaking her head dismissively. She finishes dressing, smoothing her uniform into place and adjusting her spectacles on her nose. The sensation lingers, but it is not very intense, so she pays it no mind. It's probably some error on the part of the laundresses, she muses perhaps I'll confront them later and hypnotize them to make out naked in the courtyard as punishment for mishandling my delicates.

She makes her way downstairs to the grand dining hall, the clatter of utensils and murmur of voices filling the cavernous space. As she takes her seat at the long, polished table, she feels the prickling start to intensify, a tickling sensation along the padding of the edges of the cups where most of the powder drifted after you applied it. A faint blush rises to her cheek, and she shifts a little in her seat, crossing her legs and uncrossing them again, trying to ignore the growing discomfort. You sit a distance away, hopeful as you notice these first signs of your plan for payback taking effect. You end out doing a bit of uncomfortable shifting yourself, your crack still sore and raw from the wedgie she gave you last night.

As you each go to Theoretical Wardcrafting, your shared first class of the day, Einamina sits in the front row of the lecture hall, the itching and tickling sensation in her bra growing more and more unbearable with each passing minute. At first, she tries to ignore it, focusing intently on the lecture on the impact of local leyline geology's effect on building wards being delivered from the front of the room. But as the class progresses, the feeling becomes impossible to dismiss.

She squirms in her seat, wriggling her chest back and forth in a way that does interesting things to her chest, trying to find a position that will alleviate the maddening prickle. But nothing seems to help. The sensation intensifies, the sweat worked up by her efforts only serving to stick more of the powder to her skin and spread it around, leaving the whole of her breasts itching and prickling more with every passing moment and movement.

By the time Magister Thornweave, a middle aged human, is writing out the complex spell formulas for compensating for the mana-porous nature of basalt on the chalkboard, Einamina can no longer stand the torment. With a sudden, desperate motion, she reaches up and rips open the front of her uniform top, the buttons flying in all directions and clattering to the floor.

Gasps and whispers erupt from the other students as Einamina's ample, pale breasts spill out, no longer contained by the lacey bra. But the powder has already been absorbed into her skin, so the itching continues unabated.

Einamina begins to claw and scratch at her heaving bosom with wild abandon, her nails raking over the sensitive skin, all thoughts of dignity or propriety obliterated in the face of the all consuming need to find release from the ceaseless, unbearable itching. She digs her fingers into the soft flesh, scratching and clawing in an increasingly frenzied manner. Her face is flushed, her breathing heavy as she desperately tries to relieve the maddening itch to limited avail.

Magister Thornweave, not overly fond of Einamina at the best of times- her disdain for humans extends to those teaching at the academy- pauses mid-lecture. His gaze snaps to Einamina, and his eyebrows shoot up in surprise and outrage as he takes in the sight of the noble elf girl groping herself in the middle of class.

"Einamina Faimeni!" he barks, his voice echoing through the sudden silence of the lecture hall. "What in the name of the Archmages do you think you're doing? Cease this lewd behavior at once!"

Mages spend years training mental discipline in order to gain the focus and willpower needed to cast spells, and Einamina has to summon all of that training to focus enough to put together some kind of explanation as she frantically molests her own chest. Unfortunately for her, she doesn't have quite enough focus to suppress her natural disdain for humans at this moment.

"How can you be so blind, you stubborn mongrel ape? This is obviously some kind of prank or hex meant to embarrass me, and you're just standing there like a half-wit! You should make yourself useful, and find the impudent fool who would do something like this to one of their betters!" Her imperious words are rather undercut, standing as she is bare breasted in the middle of the room, frantically jerking and scrabbling at her chest as she rants.

It's only as the magister's eyes narrow that Einamina realizes, in a rare moment of chagrin, that while speciesism is alive and well enough at the academy to speak that way to most humans, she really can't be showing that kind of disrespect to a professor. The realization is enough to make her stop digging her fingers into her tits for a moment, until the itching returns in force and with a muffled curse she starts scratching again to deaden the sensation.

The combination of disrespect and continued disobedience quashes any sympathetic impulses Magister Thornweave may have held towards Einamina. His eyes narrow in anger and disgust, and, wordlessly, he raises his hand and traces a quick, sharp gesture in the air. Einamina cries out in dismay as glowing bands of light wrap around her wrists and elbows, pinning her arms behind her head and rendering her unable to continue her scratching. The magical bindings cinch tight, forcing her to straighten up and arch her back. The motion serves to thrust her heaving, exposed breasts further out, now helpless against the itching and tickling that suffuses them.

"There will be no more of that, Lady Faimeni," Magister Thornweave says, his voice cold and hard as steel. "If you cannot control yourself, then you will remain restrained until the end of the lesson- and if you're so quick to forget modesty, perhaps spending the rest of class on display will reawaken a healthy sense of mortification in you."

Einamina opens her mouth to unleash a torrent of angry invective against Magister Thornweave, but before she can utter a single word, he silences her with another swift, sharp gesture. A glowing ball of light materializes out of the air and expands until it becomes a gag, filling Einamina's mouth and forcing her jaws wide. She tries to spit it out, but it's already grown too large.

He turns back to the class, his face still flushed and his jaw clenched tight. The students watch in stunned silence, some with open mouths and wide eyes, others trying to hide amused smirks behind their hands. Einamina, now forced to endure the maddening itch with no relief, squirms and groans softly in her seat, chest jutted out prominently by the position she's bound in. You sit back and enjoy her humiliation and torment, just desserts for what she put you through last night.

Magister Thornweave takes a deep breath, visibly struggling to regain his composure. He glares at Einamina for a long moment, his eyes hard and unforgiving behind his spectacles, before turning his attention back to the lesson.

"Now, where were we?" he asks, his voice still tight with barely restrained anger. "Ah, yes. The loss rate of mana when using basalt rock as a medium for carving wards suitable to shield a three room building."

As he continues the lesson, the classroom remains a mix of stunned silence and barely concealed snickers, with Einamina squirming and whimpering quietly in the center of it all, a live demonstration of the consequences of the elf's scorn and arrogance. You admire the expanse of creamy, jiggling elf tits now on public display as she futilely wriggles and shakes her body, trying vainly to find some relief.

With the gag muffling her screams, Einamina is reduced to moaning and whimpering desperately as the itching intensifies, the sensation now unbearable. Her body writhes in her seat, back arching and shoulders heaving, as she tries in vain to find some relief. The more she moves, the more her ample bosom bounces and jiggles with each futile twitch, drawing lewd stares and stifled laughter from her classmates.

Magister Thornweave pointedly ignores Einamina's anguished state, continuing the lesson as if nothing were amiss. He walks up and down the aisles, gesturing to the chalkboard and explaining the finer points of the spell formula. Occasionally, he pauses to fix Einamina with a stern glare, silently daring her to cause any further disturbances.

As the class progresses, Einamina's desperation grows. Her skin is streaked with red lines from her earlier scratching, and her eyes glisten with tears of mortification and fury. She squirms and writhes, the gag muffling her increasingly loud and frantic moans. Her breasts, freed from their confines, bounce and jiggle hypnotically with each anguished twitch and wiggle, providing an unintended but lewd show for her audience.

The other students watch, some with open mouths and wide eyes, others with barely concealed smirks and snickers. Whispers and giggles ripple through the room, echoing off the stone walls. Einamina's humiliation is complete, and the sight of her suffering is a delicious treat for her many detractors among the student body, although most of the elven students seem a bit stricken at seeing their idol brought so low.

As the final bell rings, Magister Thornweave dismisses the class with a curt nod, not sparing a glance for the still-struggling Einamina. The students file out, casting amused and mocking looks back at the elf as she rises and stumbles out, arms still bound, mouth still gagged, and bountiful itchy tits still bare to the world.
