The forbidden book seemed to writhe against her chest as Demma smuggled it out of the library. Though she had yet to open and read it, she could still feel its Eldritch power seeping into her. Was the corruption of her supposed to feel this pleasurable? She had no idea, but the discovery made her giddy.
Back in her room, she realized the growing sense of weight during her trek wasn't just the strain of carrying the book--her book--halfway 'cross campus. A surprising amount of brand-new boob was trying to escape through her collar as she embraced her book. Something about the psychically-tuned arcane power must've altered her physically to match her preconceived ideal. After all, an Eldritch sorceress should be equally compelling as she was sublime.
"Let's see what else changed, shall we?" she mused as she put her book aside and shucked her robes. Her new bust, freed from clothes that were now too small, hit her chest with a thud that echoed through her body. They were huge and heavy and outstanding. They outsized all of her sisters' combined.
"Oh! They're perfect!" she cooed, hefting them and letting them wobble as they spread over her palms. The sheer size of Demma's breasts was not the only thing about them that had changed. Her areola had spread out and puffed up simultaneously, engulfing her nipples. As she cupped the soft mounds, she realized they alone were bigger than her previous, paltry breasts. Why, though, had they been all but drained of color? She tilted her head as she continued to look at them. They looked... They looked almost like lips.
Then the eye opened on her chest, and she dropped her new endowments in shock. The eye's corners pointed up and down, and the pupil was an almond-shaped slit with the same orientation. It was situated at the bottom of her sternum, such that it would peek out from beneath her cleavage when dressed. The iris' color shifted between deep pink and bright purple at a rate slow enough that it was almost unnoticeable. At first, she panicked, but that was before the wave of power that started in her chest washed over her. A taste of things to come. In the grand scheme of things, such a change was a small price to pay.
"Invigorating," Demma said, half-breathless. She turned her attention back to her pilfered tome and licked her lips. "But that's nothing compared to what is going to happen--if the whispers are true." Not that she doubted them. If anything, the stories of this tome had undersold its potential to affect its wielder.
Returning to her bed, she curled her left fingers around the cover. A different energy surged up her arm when her fingertips touched the pages. Glowing angular runes burst to life just above her skin. A swarm of tingling up and down her arm followed, the sensation reminiscent of paper cuts.
SPLORCH! SPLORCH! SPLORCH!
The wet yet forceful sounds of her arm muscles' sudden expansion were audible and quite nauseating. Demma rushed to put her book aside and grab her desk trash. She struggled with the urge to hurl but succumbed despite her best efforts.
After a long moment, she put the half-filled bucket down and sat back. Her attention snapped back to her arm, forgetting her sickness as she marveled at the new definition. With her mind clear of resistance, the extent of her new physical power became clear. She was hit with the memory of holding someone aloft by the front of their robes.
All of this change was just from touching the edge of the pages? Her mind went blank except for the word 'more' repeating, over and over, until it was a buzzing sound in her ears.
Had it been any other book, she would've torn the cover off as she jerked it open. Eager to the point of vibration, she pressed her right palm to the light green pages and savored the feel of the mirrored sensations as similar runes encircled her right arm. The wet sound of the following growth was still a bit sickening, but it was also arousing for some reason.
Without hesitation, she put her left hand on her book's inside cover. The runes spread down her body. Knowing what was coming, she relaxed her mind. With the same sickening--but now very arousing noise--the energy upgraded her entire body's physique. Her boobs spread down her chest and then out around her ribs. Her hips widened across her sheets with
CRICKs
and
CRACKs
that made her gasp as the stabs of pain blossomed into pleasure. Her non-existent butt pushed against the mattress, raising her eye level, inch upon inch. Her knees rose away from the floor and seemed to retreat as she gained what had to be at least a foot of height. Above all, an even greater level of arcane power flowed through her. Her whole body tingled with energy. Yes,
this
is what she had sought. It felt like no spell would be beyond her. Not now--or ever again.
"I could stop here," she mused, more than impressed. "My sisters will be in
my
shadow for the rest of their lives..." She ran her hands down her altered body and relished her new muscles moving beneath her skin. On top of that, the transformation had seemingly heightened how her nerves triggered her sense of pleasure. Every touch felt like a lingering, loving caress.
"Yes, I'm already superhuman, but..." She glanced at her grimoire. The promise of everything beyond the title page awaited her. Not one story, not one rumor, had said anything beyond what she'd already experienced. What other remarkable, unspoken changes were just inside?
Demma flipped through her tome, looking for a spell she knew had to be there. Each time her fingers touched the page, the connection felt a tiny bit more sensual. A little more loving. Her book was her partner, after all. She needed no one else. She was so absorbed in her search that she didn't notice how the pages changed from luminescent green to that same wavering pink-purple of the eye on her chest.
Such a connection was a new thing for the book. It had never encountered someone so earnest, so enthusiastic, so... happy about being connected to it. It was surprising how easy it was binding itself to her. It knew she could be its avatar, an embodiment of its power, the first in millenia. It resolved to grow their bond until there was no longer a barrier between them and manifested the spell its new master sought.
"Ah, here it is!" Demma clapped her hands together and began to chant. Starting at her fingertip, the runes floating above her arms turned red. The line swept up her neck and over her face. There was a
SQUELCH!
as another eye opened in the middle of her forehead. Like the one on her chest, its corners pointed up and down. Unlike that eye, however, its iris was the same red hue the runes had shifted towards.
Demma was so overwhelmed by her new sixth sense that she failed to notice that her hair had lengthened past her shoulders. She also didn't see how that corrupting red spread upward from the edges. In most places, it was only an inch or two of color, but there were a couple of places where the red almost reached the runes across her shoulders. The avatar-to-be cheered at the success of her spell. Then, she bit her tongue.
Her fingers went to her mouth, bridging with them the purple-pink dust of the page, and touched her teeth. "My canines, they're... they're longer!"
Under the influence of direct contact with her grimoire's power, they grew even more. When she gasped in surprise, she inhaled the dust. Most of it settled on her tongue, but a good amount stuck to the back of her throat. Almost at once, her tongue began to itch.
"What... What's happening?" She asked, the edges of her tongue tingling even more. There was a series of subtle pinching sensations, the magic creating a fin-like structure. Every half-centimeter there was a soft, squishy, rib-like structure that gave the fin its shape. Then there was a less subtle tug as some unseen force pulled her tongue out of her mouth. Runes appeared around the stretching muscle as the event continued, and she watched in awe as it stretched out, further and further. How much longer was her tongue going to become?
The force finally relented and dropped her tongue. It landed between her tits with a
