"Are you sure you're okay with this, Derpy?" Twilight Sparkle asked, and not for the first time.

Derpy Hooves rolled her eyes. She was particularly good at rolling her eyes, though she reserved it for when she wanted to make sure somepony knew she was a little upset. It worked this time just like usual: Twilight's eyes tried to follow Derpy's as each rolled a different direction.

Twilight Sparkle blinked. Nopony could stare Derpy down—nobody.

"Ugh! Derpy!" Turning away, Twilight found herself looking back at her book.

"You're a princess, Twilight Sparkle. You spend so much of your time making sure Equestria is okay that you deserve a little time to yourself. Even if I don't really understand what you're doing, it doesn't matter. This is your not-princess-time." Settling on the couch, Derpy lifted out her knitting and began working away on it.

"But—" Twilight stopped when Derpy's hooves did. "Are you sure?"

"Mmhmm!" Derpy returned to knitting. "And when you need a hug, I promise I can do that. My hugs have the Dinky Seal of Approval."

Twilight let out her breath, unaware she'd been holding it. They have the Twilight Sparkle Seal of Approval too, after Lemon Hearts' story, Twilight thought. She looked at Derpy one more time and marveled at how much of a good friend she'd never taken the time to know better. "Thank you, Derpy."

This time, Twilight cast the revised Hayscarts' Method version three point oh point one. The only difference being it allowed a designated watcher that wouldn't trigger an early suspension.

Nightmare's Brood

by Restrained Power

No bridle, no chains attached to her hooves, and no cage. Those three things put Twilight's mind at ease right away. A hoof, however, was rubbing at one of her ears, and the feel of the caress unwound Twilight Sparkle further. A little flashback to her time with the diamond dogs pulled a smile from her.

"You like that?"

The voice was familiar to Twilight. She'd heard Nightmare Moon on two previous occasions—this marked the third. Twilight turned her head—aware there was a heavy collar around her neck—and looked up. She traced the midnight hoof along the leg it was attached to and looked further up. Nightmare Moon stood over Twilight.

"I have plans for you, pet. I'm reviving the thestral in the most expedient manner possible: I'm breeding them." Walking around Twilight, Nightmare Moon called darkness to her horn.

Magic connected with Twilight's back. She felt an ice-cold chill as Nightmare Moon's power sunk into her. Not having wings before, Twilight was shocked at the feel of two new limbs pulling free of her shoulders.

Twilight arched her spine and tilted her head back. "My queen, please do with me as pleases you." This was more Twilight's style, submission and one of her greatest nemeses doing untold things to her. Despite the strain to her body as her shoulders began to change too, Twilight managed to turn to Nightmare Moon and bow her head to the floor.

"Such a good beast, aren't you? You deserve more than those other mares I changed. How about a lot more?" Nightmare Moon unloaded more power into Twilight.

Waves of fur flowed over Twilight, dark blue/purple replacing her usual tones, even her mane and tail grew dark and unkempt. But as the new rush of power seemed done with her muscles, it poured from all over her body to focus between her back legs, and behind them.

A pinch, then the feeling of a sharp shove in her gut, and finally Twilight Sparkle had the most unique sensation of feeling her penis and balls grow. "But— But— I'm a mare!" he said.

"No." Nightmare Moon's voice was a whisper in Twilight's larger ears. "Those are mares."

Twilight Sparkle's slit eyes narrowed to the width of a hair as he followed his master's wing gesture. Pressure seemed to swell in Twilight's gut, and he felt a burn of need waft through him like a wave. Limbering up his wings, Twilight stretched them out and roared his intentions to the world in a wordless cry of lust.

The first mare didn't know what had hit her. Twilight was on her back and quickly shoved his hard shaft into her quivering body. Nightmare Moon had made Twilight into a beast, and a beast he was. He grabbed the mare by the shoulders and impaled her upon his shaft.

Sex was rough, fast, and completely alien to most of Twilight's mind, but there was something in him that knew what to do, how to mount, the best way to fuck.

"Breed them."

Twilight lost track of himself. The only things he cared about were touch and smell. The mares were enticing, his master's command insistent, and he made sure to sow seed in every womb present. So completely distracted by lust was Twilight, that he didn't realize he was on Nightmare Moon's back until his thighs connected with her rump.

The knowledge that he could please his master and fuck her at the same time briefly roused Twilight Sparkle from the haze in his own head. Turning his head, Twilight bit down at the ruff of Nightmare Moon's neck, he grabbed her chest with both wing claws, and jack-hammered himself into her.

The clutching hole of his master was too much for Twilight, and he felt his end approaching. Putting all his stamina into the rough sex, Twilight snarled at Nightmare Moon, daring her to climax before he was done.

He ended up cutting it so fine that his master only climaxed thanks to the rush of his seed into her womb.

Twilight Sparkle slumped onto Nightmare Moon's back. He jerked and pulled from her and shook himself. "My master…?" Just the sight of the dread mare sent sparks of sexual excitement through Twilight. He didn't need any further urging to revive his flagging erection.

"Come. Again."

The End

Wings were folded around Twilight. He felt strange, really strange. His body didn't move right and felt too small. But, the wings were nice.

Wuffing and sniffing at the owner of the wings, Twilight could dimly recall a pretty, gray mare. Arousal struck swift and firm, but no hardness accompanied it. Shaking her head, Twilight Sparkle tore her way free of the story's mindset.

"That was a good one." Derpy's question wasn't one. "Who wrote that one?"

"I can't—can't say." Twilight was panting for breath, and each inhale gave her the scent of another mare. The smell of Derpy sent chills through Twilight, and without caring she snuggled a little close and pressed her nose between Derpy's forelegs.

"You should probably sleep, Princess."

Twilight, suddenly, agreed.
