Shadow Milk Cookie was no stranger to deception.
He had honed his craft over lifetimes, perfecting the art of misdirection, slipping between truths and lies as easily as breathing. It was a talent, a necessity, a part of him as intrinsic as the stars were to the sky.
And yet, for all his cunning, he had somehow managed to outplay himself.
The plan had been simple.
Shift into a cat—a small, sleek, black-furred thing with striking silver eyes—and weave himself into Pure Vanilla Cookie’s presence, pestering him just enough to be a nuisance. Tugging at his robes, knocking over his scrolls, curling up right on top of whatever he was trying to read. A minor irritation, nothing more.
It was meant to be his victory. A way to amuse himself. A way to get under Pure Vanilla’s skin without consequences.
He had not accounted for one thing.
Pure Vanilla loved cats.
The moment Shadow Milk—no, the cat—had pranced into his study, Pure Vanilla had lit up. His eyes had softened, lips parting in delighted surprise, and without hesitation, he had scooped him up.
Shadow Milk had frozen, stunned, barely able to process the way Pure Vanilla had pressed him close, fingers scratching behind his ears. A deep, embarrassing purr had rattled out of him before he could stop it.
Then, the real horror began.
Pure Vanilla, with all the warmth and kindness that Shadow Milk had been trying to avoid, had declared, “You must be lost! Poor thing—don’t worry, I’ll take care of you.”
And now, Shadow Milk Cookie was in Pure Vanilla’s home, curled up on his lap, being stroked and cradled like some beloved pet.
This was not part of the plan.
He should have left. He should have immediately teleported away the moment he had the chance.
But his body refused to move.
Every time he even thought about escaping, Pure Vanilla’s fingers would scratch just under his chin, or behind his ears, or down the length of his back, right between his shoulder blades—where he couldn’t reach in this form.
And the worst part?
It felt good.
He seethed internally. This was humiliating.
And then—the bath.
Pure Vanilla had suddenly decided he was “too dirty,” scooping him up and carrying him toward the washroom with a gentle hum. Shadow Milk had struggled, wiggling in his grasp, mewling in protest.
“No need to fuss,” Pure Vanilla had chuckled, as if Shadow Milk—**a feared specter of deception and ruin—**was nothing more than an unruly house cat. “You’ll feel much better after a nice bath.”
And now here he was.
Soaked. Betrayed. Trapped in warm, lavender-scented water, wrapped in Pure Vanilla’s hands.
His fur was wet. His tail flicked irritably, ears flattened against his head, but he did not leave.
Because, as much as he loathed to admit it—
Pure Vanilla was gentle.
His hands were slow and careful, smoothing suds through his fur, rubbing warmth into the tension curled deep within him. Every time his claws twitched, ready to protest, Pure Vanilla would hush him, whispering nonsense in that soft, infuriatingly kind voice.
“There we go… nice and warm, right?”
Shadow Milk hated it.
He hated how warm the water was.
He hated how soft Pure Vanilla’s touch was.
He hated how safe he felt in his hands.
And most of all, he hated the way his body melted into it, the way he instinctively pressed into Pure Vanilla’s palms, seeking out more of that unbearable, intoxicating affection.
By the time the bath was done, Shadow Milk was limp in his grasp, bundled into a towel, purring.
This was the single worst day of his life.
Pure Vanilla, ever the fool, simply smiled, rubbing circles into his fur as he carried him back to bed. “See? That wasn’t so bad.”
Shadow Milk huffed. It was.
He should leave.
He should teleport away, shed this form, and pretend this never happened.
And yet—
When Pure Vanilla sat down, cradling him against his chest, warmth thrumming from his heartbeat, Shadow Milk did not move.
He let himself be held.
Let himself be cared for.
And—**in the lowest, most shameful moment of his life—**he curled into the embrace.
His magic shifted. His form flickered, stretching, reforming—until he was no longer a cat, but himself again, drenched and curled in Pure Vanilla’s arms.
There was a pause.
A silence too thick to ignore.
Pure Vanilla, to his credit, only smiled. “Welcome back.”
Shadow Milk did not respond.
He only closed his eyes, buried his face against Pure Vanilla’s shoulder, and muttered:
“Not a word.”
Pure Vanilla chuckled. “Alright.”
And, against all odds, Shadow Milk let himself stay.
