Spike was away, staying at Rarity's house to help her with some tricky sewing that required hands, and Twilight had the whole castle to herself. She settled into what she thought of as her living room—a pair of large, soft couches, some busy bookshelves, and a coffee table surrounded the huge fireplace. Twilight had banked the fire up with wood and magic, and settled on her coziest couch with a blanket over her.

There was one other thing that she had—a book.

Lifting the first For The Plot Book Club book up in her magic, Twilight used a quick and simple spell to randomly find the start of a chapter. She opened the book while trying to keep from seeing the title of the short story she had picked. "Here goes nothing."

Forever Bred

by The Hand

The bridle was heavy around Twilight's head—it weighed as much as a pony's freedom. A bunch of diamond dogs were walking around outside the cage she was apparently in, and though she opened her mouth to call to them, only a gurgling came from her lips. Something was inside her mouth and forcing her tongue down, keeping her from forming words.

Mind racing, Twilight remembered only one story that warned of diamond dogs: Lyra's.

"You there, pony. Come," a diamond dog said.

Twilight was confused until the dog reached in with his hand and grabbed the end of her bridle. Yanked forward, she barely kept her hooves under her as she was roughly guided to what looked like a hitching post from Dodge or Appleloosa.

No more words for her, the dog wrapped the reins attached to Twilight's bridle around the post three times, then stood back and pointed a wand at Twilight.

Light flared and Twilight Sparkle was dazzled by magic. Her body felt odd, malleable. She tried to fight it back with her own magic, but felt her horn literally suck into her head and remove any hope of her casting. Her wings itched and then, too, folded in and were absorbed by her body.

Twilight Sparkle turned and stared at herself as her hips shifted, her sleek pony legs growing shaggy gray fur, and her tail turned to a mop of a thing. The spell was changing her, remaking her into—into a dog.

She looked down then, watched as her forehooves turned into blunt-clawed paws—but not hands. Twilight made a soft whimper as the changed rushed up into her face and head. She ignored the physical changes, however, as the magic met her brain. Higher thinking became dulled, free will restrained. Twilight Sparkle felt herself grow dimmer, simpler.

"She's done. You pay good price for breeding bitch?"

The words made Twilight's ears twitch. She turned her head to see the big dog talking to another. Their words should have made perfect sense, but whenever she tried to focus on what they said, it just seemed to melt together. She whined again, until a hand found her chin.

Scratching fingers worked at Twilight's throat, and coaxed a happy little shiver from her body. She was so delighted she wagged her tail.

"I'll take her. She better be in season."

"Of course she is, and she'll always be."

"No she won't, trust me."

The hand under her chin had Twilight's full attention. Her eyes closed, the world faded away so that it was the only sensation she felt. The hand moved, eventually, and when she opened her eyes it began tugging on her bridle—her leash.

"Come on, girl. I'll get you what you really need over here."

A smell that had been forever missing in Twilight's life suddenly made itself known. Something inside her started to uncoil, and she began walking with more eagerness. She was led—by her new owner—to a pen and quickly pushed inside.

Confusion as to where she was didn't last long, as something pushed under her shaggy tail. If she weren't bridled, Twilight's mouth would have dropped open as the first lick found her folds. The second erased any hint of resistance she might have summoned, and the rest were icing on the cake.

Only the loss of the licking would pull Twilight from her absolute bliss. She lazily lifted her head from the hanging position it'd been in and looked back just as the big canine jumped on her back.

All her thinking fled, and she pushed back eagerly, her rump fishing for what she knew the dog was offering. She didn't need to wait long, or search far. A tight grip of teeth on the back of her neck came just as the dog sank into her body.

Twilight's mind further devolved into a lusty, pudding-like state as the big dog started on her. He hammered her not like a careful lover, but like a beast that has a hole to fuck. She backed up and held her stance as best she could while he seemed intent to shove all of himself into her—including the huge bulge that banged at her entrance.

Each shove the dog delivered was joined by a jerk backwards at the scruff of her neck. She didn't struggle, she didn't want to—this was perfect. More and more of him seemed inside her as he swelled, but it wasn't until a particularly hard shove that she found out what full was. The knot was already swelling, and though it was a tight fit to get it within her, she felt it swell even further.

When the wave of heat exploded inside her, so to did her own orgasm, and her last shreds of reluctance.

Soft hands, paw-hands, rubbed at her ears. Good Girl, as she thought of herself now, tilted her head up and licked the face of her owner.

"Come on, Good Girl, just push with me."

Good Girl panted as another contraction rushed through her back end. She bore down upon her pups, and begged her owner with whines to make sure they would all be okay. After all, when her pups grew a little and left her teats, she would be ready for another breeding.

The End

The experience had felt like a lifetime. Twilight's pelvic muscles twitched as a phantom pain of pregnancy echoed through her. She was Twilight Sparkle, an alicorn, and a princess, but for nearly an hour after leaving Lyra's story she was also the bitch named Good Girl who birthed champion pups for her owner—who loved her dearly, but only as a pet.

She wrapped up in blankets and checked the time: nine hours had passed, and Twilight was ready to sleep. Rolling over on her couch, Twilight wagged her tail as happy memories her mind had been urged to create within the story, reminded her of all her pups.

Twilight woke, rested, and could think clearly again. Good Girl was as much a fond memory as being just a filly was. She decided she wanted something crunchy for breakfast, and without Spike home she would need to get it herself.

Cleaning up, she prepared herself and trotted out into town. An apple was scored from Apple Blooms cart, and the moment Twilight bit into it she shivered with glee—nothing beat an Apple family apple.

Nearby, a wide smile spread over Lyra's cheeks as she watched the Princess of Friendship wag her tail like a happy dog. She actually giggled, and didn't care that her own wagged too.
