Transgendered Theatrics

“Well which one?” Big Mac asked, seeing about a dozen different cookies to choose from, and not totally sure they’d all do the same thing. “There’s gotta be a dozen different types here.”

“Any one that you want, silly!” Pinkie said, giggling and leaning in close to the tray. “They’ll all swap your gender around. Some of them just do it in… interesting ways,” she finished up, stifling another laugh. “Here, I’ll prove it to you.”

Instantly, she closed her eyes and spun the tray slightly. Keeping them closed, she picked up one of the smaller cookies from the edge of the plate and expertly tossed it into the air, jumping up and catching it in her teeth before spinning around as she landed. Big Mac chuckled before stomping his hooves in approval. “I didn’t need a show, Ponk, but thanks.”

Practically engulfing the cookie, she muttered a small, “Ooh, mint chocolate chip.” The moment she licked her lips, her whole body started to vibrate. Suddenly, she grew about three inches upward in a spurt and her nose punched outward, becoming blockier and more pronounced, her eyelashes shortened, and her hair became slightly less poofy, but still retaining that Pinkie-like charm.

As her head morphed further with finer details into the distinct stallion shape, Big Mac’s attention was turned to Pinkie’s hindquarters. Her small breasts shrunk so that they were as unnoticeable under her fur as any other pony. Her hips bucked forward, shrinking down just slightly allowing him a view of her clit which was now growing and almost three inches long.

As it grew, her vagina seemed to turn inside out, one dark pink testicle popping out followed by the other, growing substantially until their size matched most stallions. At this point, her clit had changed from a solid pink to a pink and white splotched color, and a sheath had formed in front of her newly acquired balls, she grunted once as the growth became significant, a shot of precum erupting from her tip before she went flaccid and her newly acquired tool retreated into its sheath.

Big Mac blushed a bit, turning his head. He had never been one for stallions, but upon seeing the mare he loved turn into one, he was having some dirtier thoughts. “Wowie,” the pink stallion said, his deep voice practically mesmerizing Big Mac. “This certainly is an odd feeling. Even my voice is all rugged and deep.”

Big Mac bit his lip. The idea of going to town with another stallion went from unheard of in his mind to something he desperately wanted. New thoughts and ideas flooded his mind, and he was starting to sweat at these notions. “Well, darling,” Pinkie’s voice said, sending a shiver down Big Mac’s spine. “Pick your poison and let’s see what this baby can do.” As Pinkie walked past him, he saw that the stallion was now sporting a full on erection. He gave Big Mac a wink before waltzing over to the other pastries, eyeing them deviously.

“Any flavor…” Big Mac mumbled, looking through the pile of cookies. He decided that if he had to choose one, he would at least choose his favorite. After looking for a few seconds, he spotted it, a snickerdoodle dusted with raw sugar. He absolutely loved Granny Smith’s homemade version, and he could guess that a pastry chef like Pinkie could probably get close.

Picking up the cookie delicately, he gave it a taste, taking about half of the treat in one bite. The flavor was amazing, easily beating out anything Granny Smith could ever make. The cookie was soft, tasting like it was still freshly baked. Smiling with the sugary taste, he finished up the cookie, savoring the sweet cinnamony flavor before wiping his mouth clean of residue. A few seconds passed, but unlike Pinkie, he remained the same male stallion he had always been. “Pinkie, I think ya might have a dud.”

“Really?” the pink stallion said, surprised, a look of sad curiosity spreading over his face. “I thought I covered all the cookie bases. Which one did you have?”

“I had me a good old fashioned Snickerdoodle,” Big Mac started, looking at his hooves in front of him and feeling around himself for something different. “But I thought…”

He trailed off as the look of sad curiosity on Pinkie’s gender-bent face changed to that of someone trying not to laugh at their best friend who had just accidentally walked into a pole. “It’s not a dud, Ms. Macintosh. Species changes are just a bit slower to pick up.”

“Species?” Big Mac uttered as he suddenly felt his body shudder with magical energy. “Pinkie, what do you mean ‘Species?’” Big Mac stumbled back, his stomach suddenly racked with pressure. It wasn’t painful, but it was worrisome.

“Well, I got a pony penis because I just got a boring old gender cookie,” Pinkie said, rushing over to grab a small vanilla wafer. “But you managed to get the coolest one.” Sticking out the vanilla wafer in front of Big Mac she said. “Might want to eat this, unless you like the feeling of going through puberty in a couple of seconds. It’s a hormone suppressor. It’ll keep you from going too bonkers from it all.”

Big Mac worriedly took the small offering from Pinkie’s hooves, suddenly feeling his nose jut outward. He tapped his newfound snout to see that a beak had replaced it. Within seconds, he saw his surroundings grow around him, his impressive height being lost in a flash. Pinkie seemed to almost tower an entire head above him, looking on in mesmerized curiosity. Before he had time to adjust himself to the lower viewpoint, he felt his back half rapidly get heftier.

Glancing back, he saw his tail solidify into a heavy mass like that of a lizards. The change in weight distribution caused him to stumble backwards and land square on his butt, his red tail growing longer and longer, coming to a point with a spade-like end growing on it. As it grew, he saw hardened scales grow over it. Feeling the new muscle in his brain, he flicked his tail around, in shock that he really was changing into another creature.

While he played with his new tail, he felt his head and hooves start to itch profusely. Scratching his head with his hooves, he felt slight nubs growing from his forehead. Feeling them, he realized that he was growing horns. Two bony ones from the side of his head were rapidly expanding outward. They felt more like goat horns than unicorn horns though, as he felt them curve outwards and back towards his skull. Pulling his hooves back, he saw that their tips were no longer just stubs. Claws were forming on the tips of his hardened hooves. It finally hit him that he was turning from a stallion to a dragon, and at a fairly rapid pace to boot.

A pressure erupted from his back as he turned around to see that two wings were rapidly growing from it. He grunted, the pressure from all the weight differences and bone structure changes starting to hit him . He felt the wings form before rapidly folding down to sit on his back. Giving his new muscle a flap, he smiled, excited finally at the thought of not being a pony. Before he could fully test his new wings out, he felt his arms tingle.

He watched as his arms started to grow scales, and the fur of his coat start to change to a hardened slick surface. His lower hooves had even started to become claws too. He was ecstatic, because he had heard about dragon’s versatile claws and palms, especially in the sexual nature. The thought of finally getting a real-life hand job was suddenly cut short, however, when he looked down to see that his manhood was nowhere near as large as it had been moments ago. He hadn’t even noticed that throughout all of it his impressive ten incher had shriveled to probably no bigger than two inches. Suddenly in a panic that he was about to truly swap to the other side, he started to regret letting Pinkie talk him into it.

Then his mind was changed as he watched his cock shrink to the size of a clit and felt the world flip upside down. His mind flooded with new thoughts, new wants, and new needs. Images of Pinkie’s stiff cock flashed in front of him as he felt one of his testicles retreat inside his body, the feeling setting off a million sensitive nerves in his newly-formed clit. He stuck out his tongue and started to moan as the feeling of all of it culminated in his groin. He barely registered that his normal tongue had been replaced by a forked version before he felt his other testicle join in.

Big Macintosh was now a full on female, and even with the hormone suppressants in her system, the feeling of pure sexual lust from her new organs was driving her mad. She needed to test them out, use them, abuse them, try new things with them, and she needed to do it as quickly as she could muster. Looking over at Pinkie, the new dragoness shot him a pleading look, unable to talk through all of the new feelings, her moaning finally sounding like that of a girl in heat.

But even as she laid on the floor, her vagina slick and dripping from neglect, trying to get the help from the strong and bulky stallion, she felt a pressure in her upper chest. Brushing her claws over the spot, she looked down to see that nipples were pushing themselves out from her chest, the area behind them filling up nice and full. For the second time that night, Big Macintosh was growing breasts, and the overwhelming lust that came with them was back too.

As Macintosh’s breasts grew heavier and heavier on her small frame, she slid her tail out from behind her and laid herself on her back, caressing her boobs as they slowly became covered in softer scales, pinching her nipples with her claws. She gasped at the cold touch and shut her eyes tight, an orgasmic feeling building throughout her body. Her vagina quivered in protest, her breasts getting more attention than it was. Big Mac silenced it by lifting her tail and rubbing it against her clit, poking occasionally at her new nether lips.

“Don’t start without me now,” Pinkie’s voice broke Big Mac’s lust-fueled trance. Opening her eyes and pulling her claws down from her breasts, Macintosh saw that the pink stallion was standing over top of her. “I wanna try out my bits too.”

Leaning in for a kiss, Big Mac felt Pinkie’s rock hard erection bump against her clit. Grabbing a breast with her left hand to keep herself stimulated, she caressed the cotton candy mane of Pinkie’s with her right, slipping her snake-like tongue into his mouth. Macintosh felt Pinkie’s cock pulsing above her stomach and that the stallion could use some help with his tension as well. Blindly guiding her tail up from her vagina, Big Mac wrapped it slowly around the raging boner, feeling out the size of his new manhood.

His cock came to be almost a foot in length from what she could tell with her tail, and it was as thick as a breeding stallion’s during mating season. Still slick from her own juices, Big Mac started to stroke Pinkie’s cock with her tail, squeezing ever so slightly as she did so. They stopped kissing for a second and Pinkie gasped for breath. “Oh my god, Big Mac,” he said, looking down at Macintosh’s tail working its magic. “Don’t stop,” he said, stepping just slightly backwards, his head now just above Macintosh’s grapefruit sized breasts.

Big Mac’s claw drifted down to her own sex and started to rub her sensitive lips in preparation as Pinkie leaned over and sensually licked Big Mac’s nipple. Big Mac took a sharp breath in, the feeling of warmth tingling over her stomach and down her spine to her hard clit. “Tastes like cinnamon,” Pinkie said, licking his lips and giving Big Mac a sensual gaze. Big Mac could do nothing but sit there and control her breathing as best as she could. Her mind was starting to lose focus of anything but the feeling of Pinkie’s tongue on her body and her tail on Pinkie’s cock. She was almost forgetting what the pleasure of being a male was even like. She was building up and needed release.

“K-keep going,” was all Macintosh could muster between breaths and moans, her high-pitched voice sounding as desperate as ever. “I want… I want you to make me a dragoness…”

“With pleasure, Ms. Mac,” he said, composed before wrapping his lips around her breasts, suddenly kicking Mac’s tail away from his cock. Leaning it over and lining it up as best as he could with Big Mac’s inviting vagina, she continued to service Big Mac’s sensitive new breasts, keeping her on edge as long as he could manage. Big Mac felt a bump as the tip brushed along her lips. She was about to feel what the other side was like during a memorable night.

With a slight forward thrust, Pinkie’s cock spread Big Mac’s nether-lips, penetrating her with the pink-and-white splotched rod slowly sinking deep into her. Big Mac shouted, never having known the insatiable feeling of a warm cock inside her. It felt full, tight, a million different types of pleasurable and surreal. She felt her body shudder and her vagina spasm tight as the first female orgasm she had ever experienced wracked her brain. The feeling of Pinkie’s teeth slightly nibbling her breast and the feeling of Pinkie’s balls pushed against her taint had set Big Mac over the edge.

Pinkie let go of Big Mac’s nipple, giving it’s twin a lick before saying, “And here I thought the guys always came first. Don’t worry, though. Papa Pinkie’s going to give you more than you’d ever dreamed.

Big Mac, breathless and with the energy drained from her body nodded and wrapped her claws around Pinkie’s neck, pulling his ear down to her mouth. “D-don’t…” she whispered, her orgasm finally dying off. “Don’t hold back.”

“Didn’t plan on it,” he whispered back, pulling his cock swiftly out from Big Mac, eliciting a small gasp from the dragon, who gripped his back, ready for it’s return.

“Oh,” was all Big Mac could say as Pinkie thrust himself back into her.

Pinkie pulled his impressive cock out and slammed it back in again, not holding back a thing. His strong hips started a rhythm of in, out, and in again, driving Big Mac up the wall. She wanted nothing more than to melt into a puddle of pleasure under the stallion, but with every thrust she was jolted back awake with a new wave of endorphins. The feeling of Pinkie’s balls hitting her with every stroke just further helped the cause.

They were getting into such a rhythm now that Big Mac could feel her breasts being jolted back and forth from the greater forces at work. Her vagina was red hot, almost literally with her red scales. She was gripping onto Pinkie for dear life, feeling like the tighter she held the better she felt. Her body clung to the underside of the stallion, their bellies grinding against each other, the slick scales and soft fur complimenting each other perfectly. She had even begun to wrap her tail around the stallion’s backside to keep herself supported. She was literally completely off the ground and she was loving it.

Pinkie could feel Big Mac’s claws digging into his neck and her tail squeezing the lower half of his body. He felt like a he was fucking a snake that was slowly trying to constrict him to death, but the feeling of buildup was finally coming to him, overpowering the painful feelings of the tail and hard appendages. “B-Big M-Mac,” he said, not slowing the thrusts any, hips almost acting on their own accord and the dragon squeezed tighter and tighter. “I’m… I’m about to…”

Big Mac silenced him, pulling herself up with her strong claws and planted a kiss right on the pink stallions lips, squeezing as tightly as she could to him. Immediately, the pattern of thrusting stalled as Pinkie’s penis flared up. At the moment, Big Mac climaxed again and her vagina tightened around Pinkie’s red-hot horsecock, squeezing herself tightly to the exasperated stallion.

During the kiss, she felt her vagina become warmer, the feeling of Pinkie’s cum covering the wall of her uterus. As full as she had felt before with Pinkie’s foot-long buried inside her, the feeling of all the cum that had burst from him filling every available nook and cranny that his penis couldn’t fill washed over her, giving her a new appreciation for feeling stuffed. A few seconds passed where Big Mac felt shot after shot of cum erupt from the stallion, filling her up. She could even feel some of it spill out and drip out below her. This was more cum than she had seen anypony produce.

The seconds passed and the two of them kept their lips locked, the moment never seeming to fade. They slowly let their lips depart from each other before the two gazed into each other’s eyes. “How’s that for a Pinkie Cream Pie?” Pinkie tiredly asked, Big Mac still hanging off him.

Big Mac licked her lips, giving Pinkie a wink saying, “Best Cream Pie I’ve ever tasted.” She let go of pinkie’s neck and dropped to the floor, feeling Pinkie’s limp cock slide out from her vagina. Watching the cum spill from her nether regions, she chuckled. “Fullest cream pie ever too. I don’t think I’ve ever seen or produced a load quite like that.”

Pinkie backed away from the spent dragoness, reaching a hoof out to help her up. “I’m gonna blame the cookie on that one. Probably didn’t help that I gave you that hormone wafer.”

Pulling herself up from the floor, Big Mac got used to balancing on her hind two legs, giving her wings a stretch as she had been lying on them for half the session. “I thought you said that was a hormone suppressor?”

“Eh, Suppressor, Enhancer, I get the two mixed up sometimes,” he said with a wink and his tongue sticking out.

Big Mac just rolled his eyes, instead turning his attention to his currently full pussy. “I really hope this won’t make me pregnant or anything. I’d like to try out a lot of stuff, but birthing a foal is not on my list right now.”

“Well, unless you stayed a girl for nine months,” Pinkie said, grabbing a hand towel and cleaning up the spilled jizz, throwing it into the sink before waltzing over to his chip tray. “Childbirth kinda takes a while. Besides,” he continued, grabbing two chips and throwing them in his hair, “dragons and ponies can’t have offspring silly.”

“Well not that I don’t trust you, Mr. Pie,” Big Mac started, walking awkwardly forward, still not used to the wings and tail counterbalancing his front. “But I’d rather not stick around to find out.”

“Heh, I can understand that,” Pinkie said, trotting over rather casually back to Big Mac, unlike his usual bouncy gallop. “I’d rather be a mom than a dad anyways. Hey Ms. Mac, catch!”

He tossed one of the chips towards Big Mac with a flip of his head, who caught it with her tail instinctively. “I’m gonna have to keep this one in mind for later,” Big Mac said, looking at the chip balanced on her tail. “I still gotta try out flying and all that.”

Pinkie threw the chip in the air and caught it was a satisfying crunch. “Later,” he said, shrinking back down to his original size. “We’ve got so many more things we can try.”

“I suppose you’re right,” Big Mac said flicking her tail to throw the chip in her mouth. Crunching down, she felt her body grow and her tail start to shrink, wings and horns retreating back into her skin as she slowly reverted back the the stallion she once was.
