That Special Ingredient

By: Nicole Sunstone

Pinkie Pie burst through the door to her house, expecting to surprise anyone that was on the other side. A brief flash of disappointment appeared on her face when she realized that there was no one in the main hallway of the house.

“Hello?” Pinkie sang out, walking slowly through the hallway, ready to jump up and greet whoever was coming to see who was home. As she made her way to the living room, the TV was off and there was no one sitting on either of the couches.

“Maud!” she called out in the silent house, knowing that her sister was often very silent and maybe she was just too loud to hear her response. “Are you home?”

Pinkie whispered her name again, loud enough to be heard while listening carefully for any signs of her older sister being around. Sadly, no one called back and Pinkie rested her finger on her face as she walked over to the kitchen.

“Anyone?” Pinkie called out again, noticing that the kitchen was just as barren as any of the other rooms of the house. Defeated, she sighed and slumped her head on the kitchen counter, her hair slightly deflating at the lack of fun that she was going to have due to her sister not being there. The least she could have done was leave a note, Pinkie thought to herself.

Lifting up her head, Pinkie’s face was met with yellow lined paper that had stuck to her forehead. Pulling it away, it was a note from Maud, written in very blocky and legible handwriting. Pinkie beamed and made a squee while holding the note to her chest before pulling the paper away from it, reading its message.

“Pinkie,

Out to buy groceries. Dinner is at 6. Take care of Boulder.

Maud.”

“Oh, so that’s where she went!” Pinkie said aloud, despite being the only one in the kitchen. Just then, her stomach growled and Pinkie bounced over to the refrigerator looking for a snack to eat. The fridge was fairly scarce of snack foods but had things like milk, eggs, and butter inside. Not a single can of whipped cream could be found.

“Hmm...” Pinkie pondered, reaching up into the cupboard. To her surprise, there was a box of crackers still up there. Her stomach growled again as she shot her hand into the box, expecting to get a handful of tasty, crunchy squares. She dug around more before putting her face in the box. All the crackers were gone!

“Aww, that Boulder can really eat in the middle of the night!” Pinkie pouted, looking around to see if the pet rock was anywhere around her. On occasion, Maud did entrust her to take care of him while she was out buying more food, but he was not around in the kitchen. Pulling off her bag, Pinkie tossed it on the counter as a sparkling decorated book slipped out. A shine ran across Pinkie’s eyes as she remembered where the book had come from.

“Ooh! It’s that cookbook I got from Rarity!” Pinkie smiled and picked up the tome, seeing that Rarity had bedazzled almost every inch of the cover and binding. There wasn’t a title on the book, but lots of pictures of balloons, streamers, and shiny gems that looked like candy. A perfect book for a party baker like Pinkie Pie, especially with a sparse kitchen with no snacks available. “I should make cupcakes!”

Pinkie Pie opened the book to the golden fringed pages marking the party recipes. Flipping through the instructions, she finally landed on “Party-Superfluous Fantastic Cupcakes!” Something seemed strange to Pinkie about the recipe from skimming the opening preface. It was almost as if she had read it before.

“To make enough treats for everypony, you’ll need the following ingredients” Pinkie read aloud with a confused looked on her face. “That’s not how you spell ‘everybody.’ I wonder where Rarity got this book.”

Pinkie thought long and hard before a sweet, decadent aroma tickled her nose. It smelled like vanilla, but she hadn’t even turned on the oven, let alone prepared any ingredients. Blinking three times as she noticed the soothing smells of baking fill the kitchen, Pinkie was pleasantly surprised to see all the ingredients that she needed to be arranged right in front of her.

“Wow! Even I didn’t know I could move that fast,” she exclaimed, leaning down to take another whiff of the vanilla. It was almost intoxicating at how sweet it smelled. “Maud’s going to love these cupcakes! I’m sure of it!”

As Pinkie read more of the book, she began to hum to herself. It was a cheerful rhythm that seemed almost natural to her like she had known it all her life. The song grew louder in the kitchen as she added her own lyrics for each one of the ingredients.

“Cup of flour, doo doo doo, sweet not sour, doo doo doo” Pinkie sang as she moved swiftly through the baking progress. “... of vanilla, hmm hmm hmm, never get your fill of…”

Breaking from her trance while making the initial batter and pouring it into the cupcake tray, Pinkie scratched at the side of her hip. It felt like her skirt was itching as she moved around the kitchen in a dance, but she shrugged it off and read the last sentence of the recipe.

“The last thing you need to add is a bit of rose, lily, and daisy. This will give your treats that extra dash of flavor that everypony loves!” Pinkie read the instructions, looking at them again. “Flowers? But I already put flour in the batter! And what’s with the pony in all these words?”

Pinkie stopped to think again, smelling something sour and not sweet. But as soon as her thoughts began to settle in, three bowls appeared in front of her, each labeled with the last special ingredients. Each one of them looked identical aside from the flower petals mixed in with the garnish. Following the instructions in the recipe, Pinkie took a pinch of each and added them on top of each of the cupcakes in the tray before popping them in the oven.

Setting the timer for the time listed in the book, Pinkie could already smell the sweet confectionery starting to bake. Her mouth watered as the strange itching sensation of the skirt against her thigh returned. Scratching to sooth the itch, Pinkie nibbled on her pinky finger as she tried to think of what to do next. She was afraid that she would eat her whole hand if she stayed in the kitchen while the cupcakes were baking.

“Maybe I should go to my room. The cupcakes will be fine!” Pinkie said to herself as she began to skip. As she left the kitchen, the aroma settled in Pinkie’s nose as she tripped and fell on the carpet of the living room. While hitting the ground came as a bit of shock, Pinkie didn’t feel anything but the growing itch spreading to both of her hips. Looking over to see what tripped her, she found a large rock by her boot.

“Boulder?” Pinkie asked herself, a slight haze forming over her half-lidded eyes. “I don’t remember you being that big.”

Shaking her head, Pinkie struggled to get back up as she moaned slightly. The scent of the baking treats filled her thoughts as visions of pretty, colorful ponies entered her mind. Her mouth watered, wanting to taste the cupcakes. But most of all, she wanted to be a pony herself.

She kept to the floor, losing her balance every time that her hands left the ground. While the aroma was sweet and inviting, Pinkie felt that she needed to go up to her room to try to calm down. With one hand in front of the other, she crawled to the staircase. The crawl grew faster into a trot as she sped up the stairs of the house and finally bounced her way on all fours to her room, kicking the door with her legs in a bucking motion.

Panting and stretching as she laid out on her back on the soft pink carpet of her room, Pinkie could still faintly smell the baking cupcakes despite being far away from the kitchen. It wasn’t overwhelming but very soothing. She ran her hands down the sides of her thighs, the itching sensation under her skirt still present, as she slowly moved her hands to pull the boots and socks off her feet. Smiling, she carefully caressed them as she moaned.

Looking at her petite pink toes, her vision became blurred as a full pony’s hoof came into view. Blinking to correct her vision, the hooves at the end of her legs did not disappear. Curious, she slowly caressed her hooves and felt the warm and soft pink fur that was growing up her legs. As she crawled and rolled over to get onto her hooves, Pinkie reached over and grabbed a giant green alligator plush that her sister had gotten for her on her 10th birthday,

“Gummy?” Pinkie asked out loud, looking right at the alligator as she felt its soft plush exterior replaced with the hard scales of a real reptile. The unblinking eyes continued to look at Pinkie as she felt her soul connect with that of her pony counterpart.

Moaning again, the fur spread up to her midriff and increased the intensity of the itch that started from under her skirt. Scratching at it with her fingers over the fabric did nothing but make the problem much worse. Pinkie knew from her twin life that she didn’t need her clothes on anymore and that she would be much more comfortable without them on.

Slowly unzipping her blue skirt, her eyes caught the balloon design on the side of the fabric. Pinkie’s eyes shimmered as she pulled the skirt down her hooves and noticed the same marks on the hips of her legs. She grinned and tried to stand up, her pink panties stretching from the expansion of her pony flanks.

Feeling uncomfortable, Pinkie slowly removed her underwear and let it fall to the floor under her hooves, letting all of her furs breathe. As she moaned and shook her rump, a puff of pink hair popping out of her lower back and growing longer the more she shook it, turning into the cotton-candy tail of the pink party pony that Pinkie was.

Pinkie’s marehood quivered as her pony-like changes continued. While Pinkie had always found other outlets for her pent-up energy, she felt a strong pull come from inside her as she moaned and felt her slit grow wet.

Running her hands down her chest over her t-shirt, Pinkie’s arms were too short to reach her wanting marehood. She moaned and leaned back to stretch over, admiring the soft, pink tail coming out of her furry backside but it was still too far to reach.

Pinkie fell on the floor in defeat as her legs spread out beneath her. While she was never one for guys or stallions, she wouldn’t have minded having one with her in the room at that time. Rolling on her back and sighing, Pinkie looked up and saw the stuffed alligator looking back at her. An idea hatched in Pinkie’s head.

Getting on all fours, Pinkie grabbed the plush with her hands and looked it over, noticing the hard and sturdy spines running along its scaly back. Smiling slyly, Pinkie rested Gummy on the floor next to her and straddled her legs over him.

“Think that you can help me out here, Gummy?” she asked, panting softly as her body grew hotter on top of the alligator. She slowly lowered her pony backside on top of him and moaned as she felt the sharp scales tickle her sensitive region.

“Ohhh, that’s it!” she squealed, pressing her hands on top of his head as she rocked slowly back and forth. Her shirt grew soaked in sweat as she panted and moaned as she got into her motions. After a while, Pinkie pulled off her t-shirt emblazoned with a heart and felt a soothing relief as her breasts were freed. She rocked faster as her tail twitched, the scales of Gummy getting soaked in her leaking juices.

Caressing her chest with her hands, Pinkie felt a tingling sensation from her midriff. While she was lost in the pleasure of her alligator’s assistance, she softly rubbed her stomach to spread the pink fur even further. Pinkie moaned and grinned, feeling that she was about to complete her transformation into a pony.

But the fur never went any higher than below her breasts. Instead, two sensitive nubs began to peak out of her stomach. Softly caressing the new additions, Pinkie was not afraid of what they were and that she would feel even better with them. With one hand on a breast and one caressing her stomach, the appendages grew more and more until it seemed that Pinkie had two sets of arms.

Feeling in control of the furry arms, Pinkie stretched them out in front of her to find the lack of fingers on them. It was another set of hooves! Lowering them down, she rested her hooves on her sides as she rocked even harder on her alligator friend. Moaning and panting with her hooves and arms caressing her in all the right places, she felt so close to becoming a full pony and she wanted that more than anything.

Leaning back as her slit rubbed harder against Gummy’s scales, a sense of flexibility filled her, allowing Pinkie to rub her own hind hooves as she moaned even louder. The pleasure ran over her as she finally reached the limit that she was looking for, hoping to achieve the equine muzzle that she desperately desired. As she felt the magic start to work around her head and her ears started to pony up, there was a slam of the door.

Pinkie shot up and stood on her new hooves, frantically sniffing the air for the scent of the cupcakes, the loud sound causing it to suddenly disappear. Getting up on all of her hooves and trotting over to her bedroom door, she poked her head out of the door to look down the stairs, making sure her breasts weren’t in full view. Maud had returned, holding several bags of groceries with her slate expression as she looked around slowly for any signs of Pinkie.

Trying not to make a sound, Pinkie pulled her head back into her room and slowly closed the door, leaning against the side of it. “Oh no! Maud’s home and I look like… this!” She gestured at her hooves before slumping her mostly-human head on her shoulders. “What am I going to do?”

Not long after, there was a knock at Pinkie’s door. She scrambled to get to her bed.

“Pinkie? Are you awake?” Maud asked flatly.

“Don’t come in! I’m not-” Pinkie hastily responded, trying thinking of any sort of way to make the situation better. Unfortunately, her sister did not listen and opened the door anyway. Pinkie stood frozen in her naked, half-pony centaur state while Maud stood in the doorway eating what appeared to be one of the cupcakes that Pinkie baked earlier.

“Oh. So that’s why.” Maud responded, not changing her expression. She took another bite of the cupcake. “Can I be a pony too?”
