Feral Rampage
Perhaps she had felt the wetness gathering between her legs.
"Mrrrrow...♥"
Nyx twisted and writhed, a low growl rumbling from her throat as if something about her body had grown unbearably irritating. She arched herself the way a real cat would, lapping at her own limbs, rubbing her body against anything within reach.
Every time she twisted, the suit clinging to her frame pulled tighter with a soft zip of stressed fabric. It was a special material woven from her own transformed fur, commissioned through a specialist broker who outfitted people of the shadows just like her—designed to prevent the catastrophic stripping that sometimes happened when she shifted into her Cheshire Cat form. It adapted with her powers, yes, but because mobility and stealth had been the priorities, the suit hugged every curve of her body like a second skin.
To Nyx, who had already slipped into something half-feral, that second skin felt like a cage. And with no outlet for the wetness now soaking her sex, the discomfort only grew sharper.
"Mya!"
She had been lapping at the fabric with her tongue when her claws finally slid free. Just as a cat keeps its nails sheathed until the hunt, her talons erupted and she raked them wildly in every direction.
Slash! Riiip!!
The suit—so carefully obtained for people of her profession—was shredded in an instant. She tore open the place where her sex had gone slick and the place that felt tightest of all, her chest, ripping both areas to tatters before she finally let out a satisfied cry.
"Nyan!"
The full swell of her breasts, barely hinted at beneath the suit, spilled free and bounced heavily into the open air. Her sex, drenched in arousal, met the cool room and began to drip.
Drip♥ Drip♥
"Sniff sniff... mrrrow♥"
She leaned in close to the fluid she had spilled, inhaled deeply, then jerked her head away with a dismissive flick as if it held no interest for her at all. Her gaze returned to the prey she had discovered earlier.
One man.
A man whose scent worked on every instinct and every hunger now ruling her feral mind—appetite, lust, the urge to hunt, the urge to hurt, even the urge to be hurt. All of it stirred and sharpened by the smell rolling off him.
"Myaung...♥"
With her body a little freer now, Nyx drifted closer again, drawing in more of that scent. Her expression grew slack and dreamy. Her pupils loosened the way a cat's do when it has found catnip; saliva began to drip from the corner of her mouth.
She found the place where the smell was thickest and pressed her face into it.
Nuzzle♥
Each time she rubbed her cheek there, each time she batted at it with a paw-like hand, something beneath the fabric twitched and strained against his sleep pants. The scent grew richer with every reaction, and Nyx's boldness climbed with it.
Bat♥ Bat♥
She prodded with her fingers. She rubbed her cheek along the swelling ridge. At last she even stuck out her tongue and dragged it once, slowly, across the fabric stretched tight over him.
"Ptooey!"
The soft fibers of his sleepwear tasted foul. A bit of thread caught in her mouth; she spat it out with a look of pure irritation.
"Myaaa!"
Her claws rose again. She shredded the pajama cloth that had been hiding that dense, intoxicating smell.
Slash!!
Even drowned in instinct, her strike was clean. Some residual discipline still guided her—she angled the cuts so that they never touched skin, shearing away only cloth until the tip of his sleepwear fell open and what had been hidden inside was laid bare.
Throb♥
"Sniff sniff... hnyaaaang..."
A scent that was oddly briny and heavy—and yet, to a mind claimed by the wild, more fragrant than anything else in the world. The irritation of the ruined fabric vanished from her face; her features went soft and slack again. Drool spilled freely as she leaned in close.
"Mmmph... Snow White... just what kind of book..."
Even through all of this, Siwoo did not wake. He was exhausted, sunk deep in sleep—but the true reason was Nyx herself. No matter how far the feral state had dragged her, she was still the Black Cat Lady, the master thief who had slipped every pursuit and looted villains dry. Her every motion was tuned to erase presence and kill sound; those habits lived so deep in her bones that even this state could not erase them.
Hard♥
So Siwoo slept on, stiffly erect—whether from the teasing through fabric that had been going on for minutes or from whatever dream held him, it was impossible to say.
Tap♥ Tap♥
At first Nyx only watched with mild curiosity, breathing in the scent of the rigid cock standing before her. Then, claws carefully sheathed, she brushed it with her fingers.
Twitch♥
"Mya?!"
Her tail shot straight up. She sprang backward with a startled hiss and fixed a wary stare on the twitching length. When nothing else happened, she crept forward again, slow and careful.
Poke♥ Poke♥
Twitch♥
"Nyaaang...♥"
First a light bat and a quick retreat. Next a bat without retreating. Then a series of soft prods until at last she was stroking the flushed, dark-red head with her fingertips.
Ooze♥
"Nyat?"
The gentle stimulation drew a sticky bead of pre-cum from the tip. Nyx studied the fluid on her fingers, sniffed it, decided the smell was not bad at all, and dragged her tongue across it in one long lick.
Lap♥
"...Nyaah♥"
A dense, concentrated fragrance burst across her tongue. Her expression melted once more. She returned to the head of his cock, dabbed up more of the fluid with a fingertip, and carried it to her mouth again and again.
Suck♥ Suck♥ Suck♥
For a while the only sound in the room was Nyx noisily nursing her own fingers clean. The trickle of pre-cum dried up almost as soon as it had appeared. When she tapped the tip expecting more and found almost nothing, she gave his cock a dissatisfied little shove.
Twitch♥
"Nyanyanyat..."
She stared at it, thinking in the wordless way of a beast, then slowly lowered the hand that had been teasing him.
And then—

Lick♥
Instead of her fingers, she extended that rough little tongue and gave the head a tentative lap.
Jolt!♥
"Slurp slurp... mrrrow♥"
The scent grew richer still, and the satisfaction far outstripped the meager taste she had stolen earlier from her fingertips. Her face turned serious. Like a cat that has decided the moment to seize its prey has come, she simply engulfed the entire head in one swift motion.
Shlurp♥♥
"Mmph yum yum...♥"
"Nngh..."
Even with every scrap of presence erased, the direct stimulation was enough to make Siwoo's brow crease. He still did not quite surface from sleep. Nyx kept the flushed head rolling around inside her mouth, savoring taste and fragrance alike.
Drip♥
From the sex she had torn free of the suit, arousal continued to spill, soaking the bed and the clothes where Siwoo lay. The ticklish heat between her legs made her grind her hips slowly against his leg while her tongue kept working.
Squelch♥ Squelch♥
She rubbed her dripping sex along him as if marking territory, the way an animal leaves its scent, while her mouth never stopped sucking him down. She had no knowledge and even less experience. Men had never been interesting to a girl who played villain purely for her own amusement. But the feral, animal instinct now wearing her skin knew exactly what to do to cool the fire in her body, and it moved with perfect natural ease.
Lick♥ Lick♥ Lick♥
In her half-beast form her tongue had grown a little rougher; it rasped across the head of his cock in long, deliberate strokes.
Scrape♥
The tiny barbs of that tongue scraped the sensitive underside, hunting down every last trace of fluid, swallowing every fresh bead of pre-cum without letting a single drop escape.
Shluuurp♥
What had begun as simple feeding—the urge to eat the thing that carried that dense fragrance—began to change. She learned, by pure instinct, which motions made the scent thicker, which ones made the male react. She adapted with startling speed, and soon she felt his cock begin to tremble in a new and urgent way.
Something deep in her recognized what was coming. Instead of pulling back she only worked her tongue harder, more aggressively.
Suction♥
She felt the sudden surge of scent, the promise of something about to pour out, and hollowed her cheeks, sucking him down with everything she had—
Spurt!!♥
Siwoo's cock, pushed past its limit, pulsed and flooded her mouth with semen.
"...♥♥♥!!"
The purest distillation of the pheromones and fragrance that the side effect's secondary condition had been pouring from his body. The moment her tongue touched that seed and tasted it, Nyx's eyes rolled. She licked and swallowed with feverish focus.
Lick♥ Slurp♥ Lick♥
She nursed him the way a child nurses a piece of candy, chasing every clinging strand, sucking the last sticky threads clean. Even that was not enough; she pressed the tip of her tongue into the small opening at the head and milked him for whatever still lingered in the urethra.
"Hnyaaaang...♥"
When she finally let the spit-slick cock slip free of her mouth, her face was soft and blissfully vacant. She had swallowed every drop of that pheromone-rich seed. Beast instinct and feminine instinct together planted a single command in her mind.
A faint human remnant still lived somewhere under the surface, trying to hold her back—but right now, soaked in his scent more thoroughly than she had ever been, the animal was stronger. She let the last of the brakes go.
"Mrrrow...♥"
Lift♥
She raised the sex that had been grinding against his leg. On all fours she crawled up over him, settled astride his body, and gave his cheek a slow, deliberate lick, as if she meant to burn the face of the male who would take her first deep into her memory.
Drip♥ Drip♥
Nyx's sex, flushed and dripping, hovered just above Siwoo's still-hard cock.
Press♥
Slowly, she lowered her hips.
