Tiny And Towering

“So didja like bein a girl?” Pinkie excitedly asked, her normal bounce having returned. No matter the amount of times they went at it and how much energy they expended she always seemed to be filled with some excited energy.

“I don’t recall agreeing to become a dragon,” Big Mac said, finally back on all four hooves again, patting himself down to make sure everything was back in place, “but it was a nice experience. I wouldn’t mind it again.”

“Being a guy was super-dooper fun,” she said, bouncing around Big Mac as he checked that the most important thing was back in its place, his penis. Seeing that his cock was back where it should be he watched as Pinkie bounced around him, telling him what she loved about what just happened. “I got to pound you and feel your grip on my skin and feel what it was like doing it as a guy and what it was like doing it with a dragon and the feeling of a horsecock and–”

“Pinkie,” Big Mac chuckled, cutting off the never-ending ramble the baker seemed to be stuck on. “Breathe.”

She stopped what she was doing and took a big gulp of breath in before finally finishing. “And I got to cum in you with a huge sploosh!” She even jumped up and shot her arms out, personifying the ejaculation as best as she could manage.

“You sure did,” Big Mac smiled, turning his attention back to the table full of treats, about half of them already used or explained. “So what do we have next?”

“Ooooh!” Pinkie gasped, rushing to the other side of the counter. “Well I kinda picked for you last time,” she admitted, looking a little embarrassed as she turned her head slightly away. “But, how about you tell me what you’re into and then you can pick!”

“What do you mean by that?” Big Mac questioned, raising an eyebrow at the request.

“You know,” Pinkie said, half rolling her eyes. “What turns you on? What are your kinks? I got a dessert for every occasion and every position. I just gotta know what you wanna try.”

Big Mac looked down at the table of pastries and baked goods and thought it over for a second. Shyly he turned to Pinkie, an idea in his head, but unsure of whether he should say it or not. “I…” he started before turning his head and going mute again. “I kinda…” he tried again, only to fall silent once more.

“Spit it out, cutie,” she coaxed him, leaning over the counter and resting her chin on it’s sugar-coated wooden surface. “I just turned you into a dragon-girl and fucked you silly. There’s not really much that’s worth worrying about at this stage.”

Big Mac smiled at her words realizing it was silly to withhold his kinks from the mare he had just swapped genders with. “I kinda want to be with someone… bigger…” he said, still feeling awkward, not wanting to insult the amazing lover in front of him.

“What do you mean, like a chubby bunny?” Pinkie asked, smiling and creeping towards a set of brownies to her left.

“No no, not fatter,” Big Mac corrected to a confused Pinkie who stopped creeping towards the brownie. “Just bigger.” he put a hoof to his chin trying to think of how to explain it. “Like, out of all the partners I’ve had, I’ve always been the bigger one. I want to be with someone bigger than me. Not like a giant, but just bigger, you know?”

“Gotcha,” Pinkie said with a nod, jumping back from the counter to bounce her way over to a pan of chocolates. As she bounced over, Big Mac followed her excited gaze to see what she had in mind. “These should do the trick.”

Big Mac looked at the plate and noticed that the chocolates were novelty style, and each one had a distinct shape to it. Once he leaned in close to see the shapes, he noticed that they seemed to represent the areas of the body, seeming to favor the more sensual side as he had come to expect. The pan was split right down the middle, milk chocolates to the left and white chocolates to the right.

Each of the noticeable body parts seemed to have five duplicates each. He spotted penises, vaginas, breasts, full pony models, horns, wings, rumps, and one that looked like a miniature doughnut all laid out on the pan with their twins logically laid out next to them. After a second, he realized that these were all sexual, seeing what the doughnut was supposed to represent. He elected to stay away from that one for now.

“So what’s with all the mini-dicks and boobs?” Big Mac asked, leaning in close to inspect them further. The chocolates were expertly made. Looking closer he saw very small imperfections that told him these were done by hoof, not with a mould. The chocolates were impressive enough with their exquisite structure before even considering their magical implications.

“Well,” Pinkie started, looking over all the treats on the dish. “These are grow and shrink chocolates. These chocolates will make you grow,” she said pointing to the milk chocolates, “and these make you shrink,” she finished, pointing to the white chocolates. “Everything grows or shrinks exactly what you think it grows or shrinks.”

“So like, if I were to take a chocolate vagina?” Big mac started, pointing to the milk chocolate version of the nether regions in question.

“You’d get your pussy back,” she said with a wink. “I thought you were done with that girly life though?” Pinkie stuck out her tongue at the red stallion. “Here, let me show you.” She looked over the tray for a second before pecking out chocolates as if she were a chicken. She gobbled up a horn, a set of wings, and two of the pony bodies from the milk chocolate side.

Big Mac watched as she licked her lips with an audible “yum” before he heard a gurgle. Unlike the slow transformations he had seen so far, the pink earth pony shot upwards in height, growing to be almost as big if not bigger than Princess Celestia herself. Seconds later, a pair of wings to match her impressive height surged forth from her back, pink as the rest of her, but rather fitting for her increased size. She gave her new wings a flap, wiggling her hips at the excitement of it all. But as she was testing them out, she felt a pressure start to push from her forehead.

As she closed her eyes and grunted, the pink horn of a unicorn burst out of it’s usual place, slightly covered by her hair. Pinkie stood there for a second beaming gratuitously while flapping her wings and rubbing her horn. “So if you wanted to be with someone bigger, how does a princess sound?” she giggled looking at Big Mac. “Of course, I can’t really fly or do any kind of magic, but I look the part at least.”

Big Mac just stared in awe, nodding his head. He didn’t want to tell Pinkie outright, but being with someone of royalty and Princesses have always been on the top of his list as far as fantasies were concerned. The thought of rutting a massive horse with so much power and magical ability. It was almost a taboo fantasy for him, being a farmer. He knew that Princesses could choose whoever they wanted for their desires, but he never thought he’d get the chance to service one.

“Come on big boy,” she said, pushing the chocolates towards him. “Try any of ‘em out. I’ve got plenty of extra in the fridge. Just be careful not to have too many. They’re pretty potent treats.”

“Eyup,” the stallion said, looking over at the tray again to see all the kinds of chocolates that were left. Pinkie stood for a second as Big Mac looked over the spread. Suddenly changing to a surprised expression, she reached over and nibbled on a milk chocolate vagina, giving Big Mac a wink and pushing a chocolate penis closer to him.

Big Mac took the hint, grabbing the penis and popping it into his mouth, he let it melt there and tasted the sweet flavor of milk chocolate, running down his tongue and to the back of his throat. He swallowed the morsel and felt an electrifying energy surge through his body. As he finished, he felt a swelling in between his legs to see that his nutsack had gained a few ounces and his shaft a few inches. The feeling sent chills down his body, stiffening his erection to its full extent. Surprisingly, he looked down and noticed that the tip of his penis was poking out just underneath his chest. He had gotten more length than he had thought with the chocolate.

Whistling at the size change, he looked back at the tray, devious thoughts entering his mind.Grabbing another chocolate dick, he popped one into his mouth, then two, and then three of them. He melted their bases together as Pinkie gave an audible gasp. “Might want to take a step back, Big Mac. You’re about to redefine what Big means.”

Heeding her advice, he took a step back and swallowed the three chocolate dicks. He looked down as his now visible junk and felt the chocolates energy surge through him once more. A second passed and he felt a massive pressure spread along the length of his shaft and encapsulate his balls. As the pressure built, he realized that it was becoming harder to breathe. He took quick breaths in, the pressure building. Looking down, he saw his penis shoot out another few inches, its girth almost doubling. His junk was almost as thick as his leg and nearly as twice as long.

The pressure didn’t let up however, and he felt his balls drop. Lifting a leg and looking at the damage, he saw that they were almost as big as bowling balls now, their size much larger than the shaft they were supporting. Big mac’s look of lust turned to one of worry as he realized what he had done. The pressure built as his shortened breath became shorter, the pressure reaching almost insufferable levels. “Pinkie,” he started to say, shooting the new alicorn a worried glance. Before he could ask anything, the pressure climaxed.

Moaning very loudly, he felt his penis shoot out in front of him, growing almost half a foot in length, and nearly doubling in girth again. He felt his balls fill to the brim with cum and he could feel his tip pulsing out in front of him. He could easily have leaned over and given himself a blowjob if he wasn’t already panting from the pent up sexual urges his elongated crotch was now bombarding him with.

Struggling to stand, he watched as precum dribbled out of his cock head, nearly brushing the floor despite the erection he was supporting. He fell to his side, leaning over his back and letting his cock lay down on top of him. The tip of it just went past his nose. He was baffled at the size of such a large member sitting on his frame.

“Now, I love your enthusiasm, here, Big Mac,” Pinkie said, walking over to the stallion lying on the ground, starting to involuntarily lick his own erection. “But there’s no way I’m fitting that in me.” She walked over to reveal that Big Mac’s penis was nearly the length of her body if not slightly smaller. The mare had a point. Something so big wasn’t fitting in any mare comfortably.

“I’d eat a few more growing chocolates to even it out, but I don’t think we really have the room in this kitchen for that,” she said, grabbing the tray and setting it on the floor next to Big Mac. “I’ve got another plan. Close your eyes, cutie.” Big Mac obliged immediately, realizing that whatever she could do couldn’t be weirder than anything that had happened already that night. He was ready for another adventure.

“Open,” she instructed. Big Mac silently followed her order, feeling her drop something onto his tongue. Within seconds, he tasted white chocolate melting from his breath. Another few chocolates dropped onto his tongue and started to subsequently join the first in beginning to melt. “Open your eyes and eat, Little Mac,” she said, giving his chin a stroke. In the few chocolates he tasted both milk chocolate and white chocolate, but the soft treats had already melted too much for him to feel what shapes they had been.

Swallowing the chocolates, he braced himself for the changes he knew were coming. As he waited for something to happen, he felt his back start to itch and, looking back, saw a pair of small wings poke out from his back. As they grew, he smiled, watching them form into the pegasi wings he knew best. He was excited to have wings again, even if they didn’t work like the real deal. He could tell when he had been a dragon that wings were definitely being added to his list of pleasures. At least now he could tell what the milk chocolate had been for.

As he was admiring his new red appendages, ruffling the feathers and flapping his muscles, he noticed something off about the room around him. Everything seemed bigger than he remembered. The counter in front of him was closer to his chin, Pinkie seemed even taller than she had, and a dizzying feeling of vertigo was hitting him hard. As he came to his senses and realized that this was what the white chocolate taste had been, he realized that there were at least two more in the batch that he ate.

Suddenly, the chocolates hit and hit hard as the room burst outward for him, or more accurately, he shrunk down rapidly. The counter reached his eye level then continued upward as he lost height. He shrunk more and more until he was at the level he remembered seeing when he was just a small colt. In fact, he seemed to be just smaller than your average colt. Looking up at the princessified Pinkie, she towered above him. He could tell that he would barely be able to reach her stomach with his newly acquired wings.

“How’s that for size difference?” Pinkie asked, leaning over and nuzzling his penis with her nose. At his current size, his member was probably not too much larger than it normally was full size, but on the frame of a pony no bigger than a colt it was ridiculously massive. He gulped, unable to answer Pinkie’s question by the sheer intimidating size of her towering over him. His only response was his erection doing it’s best to stand on end, his massive balls noticeably resting on the floor below it.

“One more thing before we try out your new toy,” Pinkie said, teasing Big Mac by giving his erection a small lick and sucking lightly on one of his nuts. Stepping back, she looked over the counter quickly, reaching over and grabbing a brownie. Setting it down next to his head, she continued, “You might want to have a nibble of this.”

Big Mac looked over to the brownie, much bigger than he had remembered it. He had shrunk quite a lot more than he’d imagined. “It’s a bit of a strength brownie,” Pinkie explained with a smile, eyeing Big Mac’s enormous erection. She was almost mesmerized by its size, despite the fact that it’s owner was no bigger than a foal’s. “Something to keep me from breaking you in case I go a little nuts.” Big Mac nodded his head before taking a bite of the delicious brownie. Not his favorite treat, but it was scrumptious nonetheless. Feeling re-energized, he noticed that a little bulk came to be on his lower half.

“Ready, Little Mac?” she asked, stepping over him, her massive form encapsulating his vision. He was about to get ridden by a horny alicorn giant, and he could smell the anticipation coming from her quivering nether-lips. Adrenaline rushed through his body as he prepared for it all. This was going to be something he would never be able to try with anypony else.

“E-Eyup,” he responded, lying back as Pinkie leaned in to give him a gentle kiss.

He felt Pinkie carefully grab his cock to guide it to her lower regions. Closing his eyes and letting the pink alicorn control the moment, he felt the tip brush against her enlarged labia, her powerful hooves guiding it in place. He felt precum dribble out from his tip and felt her natural lubrication drip over top his pulsing erection. Both massive mare and small stallion were already on the brink of letting go. They could feel the heat from their bodies connect and smell the bakery around them mixed with the unchecked hormones coursing through the air.

Slowly Pinkie plunged his massive cock into her vagina, letting a moan of pleasure escape her lips. Leaning back, she looked down to watch as Macintosh’s nearly two-foot-long pole slowly slide into her. Big Mac grunted, her oversized vagina still tight around his grown horsecock. He could feel her walls undulating around his horsemeat as she panted, trying to get as much stuffed into her as she could.

Slowly she sat down more and more, Big Mac’s cock disappearing into her further and further until finally, her ass hit Big Mac’s balls and she bottomed out on him. Letting her tongue hang loose, she took a deep breath and let her moan ring freely throughout the kitchen. Big Mac laid there, pinned underneath the alicorn’s ginormous posterior, his cock being squeezed as tight as it could in Pinkie. Pinkie sat for a second, trying to come back to control and let her tail slide over Big Mac’s stomach, the feeling of which pushed him further to the edge.

“Pinkie,” Big Mac grunted, the feeling starting to get to be too much. They had just barely started, but he was already ready to let loose. She was too tight, and her heat was too much. “Pinkie, I’m losing it already.”

“Oh no you don’t,” she said, pinning Big Mac to the ground with one hoof and reaching over with the other to dip it into a bowl of vanilla pudding. Picking it back out with a sizeable gob on her hoof, she thrust it into Big Mac’s face. “Eat,” she commanded. Being in no place to argue, Big Mac followed and took a bite of the pudding. The taste was nothing special, but he could feel himself back off from the edge of release. His balls still felt full and his cock ready, but his mind knew he could hold on a bit more now.

It felt like Pinkie had just heightened the level of what he could achieve, not just given him some sort of anti-aphrodisiac. Keeping her hoof on his chest, she pushed herself back up, big mac’s cock sliding out of her about half a foot before she let gravity take over, plunging his penis back into her.

The feeling of so much flesh on flesh action sent a lightning bolt to Big Mac’s brain. He shouted in pleasure as he twitched, very much under Pinkie’s control still. If he hadn’t eaten that pudding he was sure that that would have been the end of him. He could feel his balls tightening under Pinkie’s glorious fat ass, growing larger and larger. He could almost feel the cum churning in them, but he couldn’t pay attention to them for very long as pinkie pushed up and slammed back down on him hard.

He felt the ground shake around him. It really did feel like he was fucking a giantess, and he was loving every minute of it. She lifted herself back up, tingles spiraled out of control up and down Big Mac’s spine, she slammed herself back down, and Big Mac felt his balls pulse, more cum filling up inside them. Pinkie began rhythmically starting this system of actions. Up, down, moan, up, down, bigger balls, up, down, euphoria, up, and down, over and over and over again.

Big Mac watched as the alicorn used him as nothing more than a live dildo. In between the earth-shattering repetitions, he looked down to see that his balls had grown substantially. The usually baseball-sized nuts were almost the size of basketballs now, and he could feel them straining to be released. He could feel the pressure pent up. He needed release. “Pinkie…” he whimpered to no avail, the alicorn in a trance, pounding herself over and over on his cock. Sweat was dripping down her body and onto him as she relentlessly stroked his penis with her vagina’s walls. She was in her own world, oblivious to Big Mac’s needs.

After a second of moaning and pounding, Pinkie deviously looked down on Big Mac, eying the table once more. Grabbing something Big Mac couldn’t see from his point of view, she gulped it down swiftly, returning her body back to it’s usual position, starting to bounce faster and faster. Big Mac felt the pressure in his nuts rise, unsure of what pinkie had done. He could barely pay attention though, as his vision started to blur a bit, his eyes tearing up at the emotion of it all.

He watched as Pinkie sped up more and more, the pounding becoming greater and greater. He could do nothing but lie there and take it all in when he noticed that Pinkie’s clitorus had grown by quite a lot. Blinking a few times in a futile attempt to whisk away the tears, he saw what Pinkie had done. A penis had grown from her clit, and it was as erect as it could have been, precum almost bursting out of it at an alarming rate.

Instinctively, Big Mac reached up and stroked it as Pinkie kept up her mind-blowing sex. With each hit, the pleasure seemed to build, and with each second, he could feel her dick pulse. The seconds became slower, and Big Mac could feel his heart quicken. He was there. The edge was finally in sight. He could feel it. He could smell it, and he could tell from Pinkie’s actions that she was right there with him.

And then the world skipped a beat. Pinkie’s cock quivered and her rhythm stuttered. All it took was this one inconsistency, and Big Mac felt his floodgates open. He let go and almost like a cannon, felt his hot semen surge into Pinkie’s equally hot womb. He shuddered, again and again, shooting more and more of his sticky milk out. Pinkie shouted out at the feeling and he felt shudders course up and down her body, just furthering his own orgasm. Closing his eyes at the last second, he felt Pinkie’s penis wobble and stiffen before her own overzealous semen hit him square in the face.

Spurt after spurt came out, covering his nose, his eyelids, his lips. Without really considering what he was doing, he opened his mouth, letting a few of the final ejaculations land squarely on his tongue. The salty bitter taste he remembered was there, but less pungent than he had remembered. Swallowing what was there, he laid back, his own orgasm still knocking him sideways. He felt his seed spill out onto his legs and onto the floor below him. More came out and more and more until he was nearly lying in a puddle of his own spunk.

Lying there for a second, he kept his eyes shut, Pinkie’s cum covering his face, his body still shuddering as his orgasm seemed to endlessly pump cum into the pink pony on top of him. He felt her shudder before hearing a small “O-Oopsie,” Seconds later, he felt a shaking tongue lightly glide over his face, cleaning up as much semen as it could from the used stallion. Finally, Big Mac felt his balls lighten and his cock soften as the last few spurts pumped into Pinkie. The moment was over, and Big Mac could feel himself covered in more semen than he thought was even possible for a horse to produce in a lifetime, much less one session.

Opening his eyes, he saw Pinkie’s shaking form, belly slightly distended from the amount of cum she had just taken in. “I’ll g-get you a towel in a s-second,” she barely gathered the strength to say. Lifting herself slowly up from Big Mac’s penis, she watched as his cum-covered cock appeared below her. He was still amazed that even for her size, she took the whole thing in down to his balls.

Picking herself up, she stumbled her way over to a kitchen drawer, her pussy dripping cum the entire way over. Big Mac let his flaccid penis fall over his shoulder again, some cum dribbling out from it’s tip and onto the floor next to him. Glancing around to see the pony-sized puddle of stallion-juice, he decided it wasn’t going to be much of a problem. Hearing a crunch, he saw Pinkie’s usual face and body stumble over to him, her energy somewhat doused finally.

She handed him a towel and a reversal chip. “That was the best,” she said, as big mac took the chip, finally growing back to his usual size, and his massive shlong regressing back to it’s normal hefty, but not gigantic, size.

“Eyup,” he agreed, taking the towel and doing his best to get all the semen out of his mane and fur. Unfortunately a lot of it was there to try to get rid of.

“Heh,” Pinkie giggled, still out of breath from the session. “Why don’t you go take a bath upstairs and get that gunk out of your fur. Goodness knows you got more than I did. I’ll clean all this up.” She pointed to the puddle of cum and the tray of chocolates rustled about. “Then we can have some more fun.”

“Eyup,” Big Mac agreed. He was curious what else they possibly had that they could even do at this point. Whatever it was, Pinkie always seemed to have something else in mind. He was excited to find out what.
