“Nngh!” Rarity tensed as a glob of thick precum collided with her dresser. Her tail, moving with nearly a mind of its own, tightened itself quickly around her shaft. Not yet. The floodgates were straining, the pressure of her building orgasm mounting ever higher. Her hips bucked impotently, breasts bobbing and wobbling in her pulled-down top. Every last nerve felt on fire, begging to be touched, stroked, caressed. She wanted release. Needed release. But she couldn’t have it just yet. She needed permission, first.

“Oh, poor thing,” the Rarity in her reflection sighed. The mirror, held aloft by her magic, showed only her desperate, needy face. But in her mind’s eye, it showed something very different: a confident, dominant Rarity; a mistress, a goddess, looking down on her like a lost puppy. The mirror Rarity glanced down to her cock, twitching and throbbing as her tail teased it with feather-light touches. “You want it so badly, don’t you, dear?”

“Yes, Mistress!” Rarity gasped. She squirmed atop her bed, arms kept dutifully at her side. Oh, how she wanted to touch herself, to run her hands over every last inch of her warm, supple flesh. But she was a good pet, and good pets obeyed Mistress’s orders. “I want it! I want it so much, I’ll do anything!”

“Anything?” Mistress grinned, tasting the word on her lips. Rarity’s tail sped up, and a groan escaped as its airy touch danced over the sensitive skin of her cock. “I’ll hold you to that, then. Mistress has so many interesting plans for you, and all her future pets. In fact, I might ask you to find me some.”

Rarity whimpered, barely cognizant of her Mistress’s musings. “Yes, Mistress, more pets. My friends, even! The whole town of Ponyville! Whatever Mistress wants!” She just needed one thing now, and only one thing...

“Good pet,” the reflected Rarity purred. “You may cum.”

Rarity’s eyes rolled back into her head, her world gone white as the orgasm hit. A rope of gooey cum splattered against her mirror, caking the glass with her arousal. Whatever Mistress wants, the refrain repeated in her head, all other thought leaving her head as spurt upon spurt of hot seed splattered over her room. Whatever Mistress wants.

Her narcissism truly knew no limits...
