The Night's Feathered Caress

The flight to the Castle of the Two Sisters hadn't taken long; Rainbow had led the way between the dark trees, Fluttershy following closely behind. The crumbling castle stood large and foreboding, nestled amidst the fog.

The two entered through a window, coming into a long hall. At one end, cast in shadow, sat an ornate stone throne, and upon it sat the queen of the night herself.

Rainbow landed before it, prostrating herself to her queen. Fluttershy did the same, keeping her head low.

"So, you've returned, my most loyal servant." Nightmare Moon said. "And you've brought back another, I see."

"Yes, my queen," Rainbow said, her body still pressed to the floor. "As you ordered!"

"Good work, my shadowbolt." Her slit eyes turned on Fluttershy.

"Fluttershy. Come forward."

She rose, eager to obey the command, though her legs trembled. She approached the throne.

Nightmare Moon stood, climbing off her throne and strolling towards the quivering pegasus on her long, slender legs. She walked a full circle around her, looking up and down her body.

"You are quite beautiful, Fluttershy," The pegasus blushed.

"I witnessed what you accomplished with the manticor, how you easily tamed the ferocious beast with only a few words. There are many more monsters in this forest, monsters that would make fine additions to my armies. Your gift would serve us well in bringing them under my command."

"Yes, my queen," Fluttershy said.

"And yet," Nightmare Moon continued, coming to a stop before her, "You are weak. You are too kind, Fluttershy, too timid. You are a coward."

"I'I'm sorry, my queen." The dismissal brought her close to tears, and she hung her head in shame.

Nightmare Moon caught her chin with a hoof, tilting it up until they were looking into each other's eyes.

"No need for that, now. Fluttershy, what do you desire most?"

"To serve you, my queen!"

"Good," she purred. "Who do you belong to?"

"You, my queen!" Fluttershy answered.

"But you don't yet, do you?" Nightmare Moon said. "When Rainbow Dash became my shadowbolt, she gave herself to me completely. I bestowed upon her a mark of loyalty, making her mine in soul, as well as body and mind. She is mine in the totality of her being. You are not mine yet."

She leaned closer, her the gleaming fangs of her smile only inches from Fluttershy's muzzle.

"But you could be."

"...Please..." Fluttershy said.

"Yes, Fluttershy?"

Fluttershy looked into Nightmare Moon's eyes and smiled. She stepped back, turned around and presented herself to her queen, her nethers already moist with anticipation.

"Please, my queen... Make me yours!"

Nightmare Moon grinned.

"With pleasure."

The ethereal cloud of her mane whipped out, four tendrils taking shape and twisting up Fluttershy's legs, another pair taking hold of her wings. They lifted her into the air without protest, spreading all six appendages apart. More came forth, one grabbing her tail and yanking it up and out of the way, while another wrapped gently around her throat before slipping up her face and covering her eyes.

She hung there, every part of her body held in Nightmare Moon's frigid grasp. She couldn't see, she couldn't move; all she could do was wait in the tentacles' icy embrace.

And then it began.

Something brushed against her lips; she eagerly opened them, inviting it inside. It entered, forcing its way down her throat as she caressed it with her tongue. and lips.

At the same time, more tendrils pushed their way into her ass and her dripping pussy, their girth stretching her and making her moan into the member in her mouth. They began pumping, in and out, alternating orifices, rocking Fluttershy's entire body with each motion.

Nightmare Moon's voice called to her in the darkness.

"You are eager, aren't you?"

Fluttershy couldn't answer, busy as her mouth was.

"But, as I told you, you are weak. I cannot allow weakness in my servants. I cannot use you as you are," Nightmare Moon said.

"So, I will just have to fix you."

A fountain erupted withing Fluttershy's head, thoughts and images flowing into her, more coming with each thrust into her.

"Your kindness."

Images of her ordering a manticore to attack a platoon of royal guards flooded her mind. She saw herself standing over the carnage, laughing at the soldiers' pain. It seemed wrong, somehow, but the pleasure distracted her, ruining her focus and letting the thoughts seep in. When she focused on them again, they felt right. Why had she thought otherwise? This was who she was meant to be.

"Your cowardice."

Visions of her riding into battle against her queen's foes, an army at her sides. The pleasure overwhelmed her again, a particularly stron thrust into her ass sending her shouting into her moving gag.

"Your timidity."

Her, barking orders, hurting any who disobeyed, enjoying it. She liked what she saw.

She could feel the orgasm coming.

"All gone," Nightmare Moon whispered into her ear. "Now, you are perfect. Now, I can make you mine."

The motions of the tentacles sped up, bringing her closer to climax even as a sharp pain lit her flanks. She knew what it was; her queen was branding her, finally taking away the last part of her that didn't belong to Nightmare Moon, making Fluttershy hers completely. She would serve her queen forever. It was her destiny.

The thought pushed her over the edge, and she shouted as she came even harder than she had to Dash's hoof earlier. The tentacles retreated, her fluids trailing and spilling out after them. The one covering her eyes uncurled too, unwrapping itself from her head and neck as the one in her throat slid out. She drooped, gasping for breath as she was lowered gently to the ground.

She could see Rainbow off to the side with her own hoof between her legs, and it almost made her smile.

Fluttershy groggily twisted her head around to look at her flanks. Her butterflies were no more; in their place, a trio of bats encircled by a ring of spikes.

Something wrapped snugly around her neck and clicked shut. Probing it with a hoof, Fluttershy found it to be a spiked collar, a match to the one on her flank.

"You are mine now, Fluttershy," Nightmare Moon said. "Mind, body, and now soul. Forever."

As she fell into unconsciousness, Fluttershy knew she would want it no other way.
