Mimi's teeth pricked her.

Petra’s thighs trembled as Mimi’s tongue worked in relentless, sloppy circles—each wet stroke sending jolts of pleasure up her spine. The sharp pricks of tiny goblin teeth against her sensitive flesh barely registered, lost in the overwhelming heat of Mimi’s mouth. A whimper tore from Petra’s throat as her hips jerked forward, grinding shamelessly against the creature’s face.

Mimi growled, the vibration buzzing against Petra’s clit as her stubby fingers dug into soft thighs, pulling her closer. The taste—salty, sweet, hers—drove the goblin wild. Her own cunt throbbed, dripping slick between her legs as she rutted against the floor, the rough friction doing little to soothe the ache. But she didn’t care. Not when Petra’s moans were getting louder, not when her body was arching like she was begging for it.

Then, Petra’s legs—shrinking, her skin tingling with the same unnatural heat that had claimed Mira—tightened around Mimi’s head, locking her in place. The nerd’s breath hitched as her hips stuttered, her once-lanky frame compressing, her thighs plumping with soft, jiggly flesh.

“F-fuck—!” Petra gasped, her voice pitching higher, almost singsong. Her fingers tangled in Mimi’s wild hair, pulling as pleasure coiled tight in her gut. The changes burned through her, her thoughts dissolving into static as her panties—what was left of them—strained against her rounding hips.

Mimi felt it too. The way Petra’s body yielded, the way her scent thickened, sweeter, more goblin. A guttural giggle bubbled up as she redoubled her efforts, tongue plunging deeper, lapping up every drop. Petra’s back arched off the lockers, a broken moan spilling from her lips—sluttier now, needier.

Petra’s skirt tore at the seams as her ass bloomed, round and plush, the fabric straining before giving way entirely. Her blouse hung loose for half a second before her tits swelled, perky and full, the buttons pinging off one by one. Green tinged her skin, creeping up her arms in patches, her nails darkening into sharp little points.

The last remnants of Petra’s school uniform crumbled like dried leaves, disintegrating into dust against her rapidly changing skin. Like Mira before her, her once-smooth armpits prickled as thick, but soft hair sprouted in dark tufts, the same soft curls bursting between her thighs in an untamed nest. The air was thick with the musky scent of sweat and slick as her body writhed, her new loincloth—scraps of leather barely covering her swollen cunt—materializing with a whisper against her feverish skin.

Mimi’s claws slipped, slick with sweat and arousal, and Petra collapsed onto the cold tile with a yelp. The impact jolted her back to awareness for one fleeting, horrifying second. Her vision swam, but she could see it—her hands, her claws, green-skinned and trembling. She could feel it—the way her body had shrunk, compact and plush, her thighs rubbing together with every frantic twitch.

“N-no,” Petra slurred, her voice higher like an impy gremlin, the words tangling in her throat. She scrambled backward, her bare ass scraping against the floor. “I don’t wanna go. I don’t wanna go. I don’t wann—”

Then—

Pop.

Petra’s mouth fell open in a silent gasp as her thoughts dripped away, seeping out of her like honey from a split hive. Her memories—human, fragile—trickled down her thighs, mingling with the slick pooling beneath her. Her ears, long and drooping now, twitched as the last dregs of intelligence leaked from them, leaving behind only hunger, only need.

Mimi was on her in an instant, her tiny body thrumming with excitement. She could smell it—Petra’s final surrender, the way her fear melted into something thick and syrupy-sweet. The new goblin’s chest heaved, her tits bouncing with every ragged breath, her nipples stiff and aching.

Petra—no, Pipi—blinked up at her, dazed. Then, with a guttural giggle, she spread her legs, her claws digging into her own plush thighs. Her cunt glistened, swollen and begging, the scent of it flooding the hallway like cheap perfume.

Mimi didn’t hesitate. She lunged, her tongue dragging a wet stripe from Pipi’s clit to her soaked entrance, lapping at her with sloppy, starving strokes.
