The book hovered just to the side and above Apple Seed. "Then peel back the…" As Twilight Sparkle, Princess of Friendship, peeled back the diaper her color shifted to green. "How can you make that kind of smell from just milk?" Her tone was anything but hostile, she smiled down at the colt and gathered up the mess, casting a quick spell to clean her foal down. Leaning down, she nuzzled the colt's belly and got a giggle from him.

Laughing in delight at how silly his dam was, Apple's laughter increased as relief hit him. Then mummy started being even more silly!

"You okay Twi?" Gel poked his head in, a little changeling filly riding on his back, gazing around with slit, green eyes. "Uh, Twilight, you are supposed to avoid that…" He moved quickly to his wife, tossing a towel up so she could clean the mess from her.

"It's all the book's fault. It doesn't tell you everything!" Twilight used a second spell to make sure she cleared her foal's pee away. "And you, that must have been quite funny!" Any annoyance was lost, she was cooing over the colt, her magic tugging a fresh cloth diaper up and onto him.

Twilight Velvet entered through the open door. "Okay, both of you, shoo." She plucked a giggling filly from Gel's back and the grinning colt from before Twilight. "This is your daily 'time off' and it begins now. Relax, have some fun, do whatever you want but it shan't be foal related."

"But-" Twilight Sparkle barely got a word out in protest to her mom before Gel lowered his head and butted her toward the door. "Gel…"

"No 'but's, your mom is only going to be here for a week, I intend to make the most of it. You know that book you were talking about?" Gel managed to but Twilight all the way out the door and cerise magic closed it behind them.

"The new Game of Pones?" Twilight's emotions shifted right into excitement. "You didn't? It isn't out yet!"

"No, it isn't out yet. But when a prince sends a letter to a writer, telling him of a pregnant princess who loves his work, well, sometimes things happen. I have the edited manuscript up in your lib-" Gel didn't get any further, he had an alicorn pinning his lips with her own, her wings flared up, and tasting of the most delightful mix of happiness and love. "Twi… you will make me drunk with that much love." Gel nuzzled her cheek and kissed her again.

"I can't believe you got that!" Twilight's step had turned into a prance as she, with a wing around Gel, led the charge to a nice snuggle and some reading.

"Okay, they shouldn't be casting any such spells on you again. Even if they are the most adept of unicorns, bypassing your magic, they aren't going to stop mine!" Twisty let the power in her horn fade, the glowing bubble of green around Celestia fading. "Did we get the photo?"

"It is being developed." Luna wore a happy smile on her snout. "Do you think A-" She halted and narrowed her eyes. "Do you think your stallion might be able to do something for me, too?"

Celestia spread her wings and twisted side to side. The slight bulge in her midsection didn't hinder her yet, and she hoped it wouldn't slow her down too much. "I think his services were a once off deal. But still, couldn't dear Twisty become a strong stallion and service you?"

"I could become a stallion and fill you with eggs!" Twisty lifted a hoof up, in clear imitation of the statue of Luna that had been built in the garden. "The eggs would be doubled."

A pillow flew from Luna, guided by her magic, directly at the changeling queen. "Eggs are fun… really fun, in fact." She adjusted her position on a pile of cushions. "But that feeling of slow swelling… I envy you, Tia." The dark alicorn showed no actual sign of annoyance at it, however.

"Then when my foal is out, you will be next. Maybe I will need to talk to Twilight and her friends… particularly one of her friends." Celestia spooned up some cake and ate it thoughtfully. "But until then, I promise you, Lulu, you are as much my foal's mother as I am." The two princesses leaned together, Celestia giving Luna a taste of the cake on her lips, and tongue.

"You two are so hot when you do that." Twisty had every bit of the stature the two alicorns had. She stepped closer and leaned in to Luna's ear, voice lowering to a whisper. "When Tia has her foal, let's go back to Ponyville, find whatever it was that made her stallion a stallion, and have her fill your belly with a foal."

Celestia jerked back from the suddenly shocked Luna. "What did you say to her?" She looked at Luna intently. "It was something naughty."

The alicorn Princess of the Night turned to Twisty, her expression that of intense love and desire. "We will do this, I love this plan." She leaned into the changeling, lifting forelegs to hug her tight. But Luna's gaze landed on Celestia, giving her big sister a wink while she licked her lips.

"On second thoughts… don't tell me, make it a surprise…" Celestia was every bit as hot as Twisty had said they were, but the anticipation would only grow and eat at her more. "I love you both so much." She joined the hug, managing to overwhelm Twisty between the two of them and showering the changeling that had brought them together, with kisses.

Rarity yawned, her tongue curling a little. Memories came back, of being stuffed full by Growl. She couldn't say it had been bad, she might have wanted a little more warning next time… but there would be a next time. "Growl? Is that you?" She tried to roll to her hooves only to find things feeling very different.

"Where else Growl be?" The diamond dog in question turned his big shaggy head. Rarity could hear the slow thumping of his tail wagging. "How bitch like?"

"I am not a bitch!" Rarity tried to stomp a hoof, but only a soft thud was heard. She looked down at her paw, her eyes blinking a few times. "What… what happened?"

"You were pony. When diamond dog breed pony, they become bitch." Growl reached out, giving a tug on the leash that still led to Rarity's collar. The former pony's head jerked forward and her lips met Growl's. It aroused Rarity, to be controlled a little. She started to kiss Growl but when encouraged, he thrust his tongue forward, only to have sharp teeth clamp down on it. "Owth!"

Rarity stood up, one of her paws reaching out to yank the leash handle from the diamond dog. The moment she had it she let go of his tongue. "Bad dog!"

"Ooo bith me!" Growl reached up with both paws, cradling his hurt tongue. "Why?"

"Because you forced me… well, you did this to me!" Rarity's anger was roused, her hackles were up and she felt a fire burning inside. "You will first apologize, then you will tell me how to undo this… I don't even have my horn!"

"Me thowwy!" Growl was rubbing at his snout, trying to hide from the angry female's wrath. "Didn't think would mind, will have pups, when they raised, turn back! Really!"

"Pups? You mean…" Rarity looked down, realizing she was standing upright. She stared at her belly in shock. "Pups…"

Growl made a snatch for the leash and secured the handle, tugging it. "Yes, pups. Growl make extra sure." He pulled the bitch off balance and Rarity crashed down to all fours. With her balance messed up thanks to being a whole new species, Rarity didn't realize what Growl was up to until his barrel pressed against her spine, and then her new body sparked into instinct. Without knowing what it was doing, the former pony pushed backwards.

"Good bitch." Growl felt his shaft press against soft, velvet-like flesh and he let go of the control he had maintained. His body surged forward, his hands transferred the leash to his mouth again and he jerked back with his neck, pulling Rarity further onto him.

A battle was lost before Rarity even knew she was fighting it. Her body wanted and needed this so much that it overwhelmed her brain, painting a picture of her well stuffed and bred, and feeding her mind enough endorphin that it became something she really wanted. The leash pulling her back wasn't needed, Rarity ground herself backwards, meeting the rutting diamond dog's thrusts with her plot, feeling him bottom out.

Growl's knot was swelling, but unlike the previous night it was moving in and out of his bitch a lot easier. Rarity's body was made for this and it wasn't until it had really swollen that she felt it rub delightfully, then bind within her. With his tie complete, Growl sped up, hips a blur of motion. But it was when Rarity started to howl, her orgasm tearing her away to complete bliss, that he unloaded. Driving his hips hard against the bitch's rear, Growl howled too, his head beside Rarity's.

"What is that? Diamond dogs?" Scootaloo was flying in the dark, but Sweetie's horn was flaring up well with light.

"Ah think so." Apple Bloom looked around for light other than her friends, but could see none. "Where is it comin' from?"

"Overr herre!" Aloe trotted forward to a hole in the ground just as the howling cut off. "Mizz Rrarity muzt be in dere." She gestured to the dirty hole with a shaking hoof.

"Sizter, we muwt go on, who knowz what ze monzters arre doing to herr." Lotus moved up beside her sister but had the same feeling. With the fillies accompanying them, they started to delve down into the hole, ignoring the dirt that was covering their formerly pristine hooves.

"Rarity?" Sweetie Belle was pouring all her magic into her horn, keeping the light as bright as she could without it sputtering. "Rarity! Where are you?"

Feeling the tie slowly go down, Rarity heard something that surprised her, her little sister. "Sweetie?" She jerked upwards, yanking the leash from Growl's mouth, yanking him from her depths, leaving her a little sore. "Sweetie Belle!"

"Where going, bitch?" Growl made a snatch for the leash and grasped it just before the former unicorn got away. With a hard jerk he pulled on it, leaving Rarity falling in a heap and whining in shock. "Who this? More ponies? Growl get many bitches!"

Sweetie Belle, Scootaloo, Apple Bloom, and the two spa ponies saw quite a sight when they rounded the corner. They had been searching underground for the better part of a quarter of an hour, but what they saw shocked them all to full readiness. Two diamond dogs were fighting and it looked like the off-white one was definitely winning.

"No no no! You are a bad dog!" Rarity snarled and growled, biting and slashing at Growl over and over. She ignored his every protest until she heard a soft voice, raised in song. "Sweetie Be-" She got no more words out, the lullaby sinking quickly into her head and heart, making her so drowsy and sleepy that she couldn't keep her head up.

Once both diamond dogs were asleep, Sweetie stopped singing. She was staring at the white dog. "She said my name! How does a diamond dog know my name?"

"What?" Scootaloo, still with the cotton buds in her ears, couldn't even hear the question.

"I SAID, HOW DID SHE KNOW MY NAME?" Sweetie tried yelling, but all that managed to do was encourage the darker gray dog to start snoring, his paw gripping the leash leading to the other.

"Pleaze, calm down." Aloe had her ears clear and was approaching the two. "You zaid zey knew yourr name?"

"She said 'Sweetie' just as I started singing…" Sweetie Belle quickly put two and two together and rushed over to the collared diamond dog, shaking the white fuzzy canine. "Rarity?"

Her dream was snatched away, the lovely dream of a nice dog… Rarity jerked awake, her brain fighting off the memory of the dream. A soft white cheek was pressed to her muzzle. "Sweetie?" The word sounded a little more rough than usual, coming from a mouth filled with teeth.

"Rarity!" Sweetie Belle was wrapped tight around the dog now, hugging the bitch tightly. "What… what happened to you?"

Lifting her paws up, Rarity worked at the collar while she spoke. "You are not going to believe it. He is asleep?" She tilted her nose toward Growl.

"He won't wake, unless we shake him, for at least two hours." Scootaloo trotted up beside her fellow crusader. "That really you Rarity?"

The former unicorn nodded and finally got the collar loose. Pulling back, she jerked her head free of it and dropped it beside Growl. "How do you know how long it takes?" The thought came to Rarity, even as she stretched and got up, still hugging Sweetie.

"Yer sister had ta test it on somepony… Scootaloo pulled the shortest straw." Apple Bloom looked back toward the way they had come in. "Ah don't suppose you know the way out?"

Rarity stood upright, lifting Sweetie Belle into her strong arms. It felt odd to be standing like this… like Twilight had described humans as standing. "I think I know the way. I just want to get out of here."

"Zat iz a zentiment we sharre." Aloe wasn't sure about this, but if Sweetie Belle thought it was Rarity, it was enough for her.

Poor Rarity, even having to fight her own body to try and get free. This is not fair!
