The thick doors of ornate crystal slid shut, locking themselves in place with a loud click. As the fresh air helped his head clear, Mac was suddenly very aware of the fact that he was still naked.

He panicked, and whirled around, trying to move the heavy crystal barrier in front of him to get his indecency out of public view. However, the herculean strength he had felt so little time ago seemed to have left him entirely.

He tried covering his shame with his hands, but it was like trying to cover a house with a single fig leaf. Luckily, he couldn’t see anyone around, so no-one was yet scandalised. He couldn’t go anywhere and risk anyone seeing him in the afternoon sun. What the hay was he going to do?

“PSSST!”

He cast his eyes around, darting from building to building rapidly, looking for the source of the hissing, the colour draining from his face. Had someone seen him? Was there someone-

“PSST! Big Mac! Over here!” The voice hissed at him again, until he saw it - a mane of wild, curly pink hair, the salmon coat, and a hand covering each eye.

“Err, hello, Pinkie.”

“Hiya, Big Mac! Did you forget to put on clothes before you went out? Thats pretty forgetful. Maybe you should keep a note on you to tell you that you need to wear your clothes. Oh, gosh, I forgot, you’re naked? Where would you keep it?”

Oh no. Not her. Of all the ponies he could have run into, it had to be one of the most childlike and innocent ponies in town. Celestia, he couldn’t imagine how traumatized she would be if she saw him like that. He had to get away from her, and from everyone, until he could find some way to get decent.

There was nowhere for him to run, and nothing to hide him. His chest heaved as his breathing quickened, beads of sweat breaking out on his brow, his eyes darting wildly as he started to panic. It was like a bad dream.

He stopped. Breathing slowly, he took stock of the situation, his usual calm demeanor returning.

“Pinkie, Ah’m gonna need ya tah keep yer hands over yer eyes for now.”

Pinkie giggled. “Okie dokie, Big Macintokey. Are we gonna play hide and seek? Cause you look like you want to find someplace to hide.” She kept her hands covering her eyes, that same childlike grin plastering her face. Mac needed to think of some way to go unnoticed and think of it fast.

His stomach interrupted his search to give another loud rumble.

Pinkie kept her eyes covered. “Big Mac, was that your tummy rumbling, or is there a big dragon around? Either way, we should get over the sugarcube corner.”

“Well, ah-” Mac struggled to explain to her what was going on “-ah’m pretty indecent right now”

“Oh, thats no problem.” She reached her left hand into a flower pot by her feet, and pulled out a pair of midnight black trousers in precisely his size. “I have magic pants stashed all over Ponyville, in case of magic pants emergencies”.

Mac accepted the outstretched pair hastily and slipped them on, long since stopping being shocked by Pinkie’s weirdness. As he slipped them on, it felt strange, like he was submerging himself in a cold bath. As he stretched the remarkably elastic waistline over his cock and balls, he noticed that they seemed to disappear from view, and when he released it, letting the waistline snap back to his abs, there was no bulge at all, merely a flat smooth substance.

“Are we still playing hide and seek?”

Mac looked up at her. “No, Pinkie. Ya can open yer eyes now.”

Her eyes fell upon him as her hands fell awayShe did so, looking up at him. “Wowee, Big Mac, you sure got a lot bigger. We should start calling you Bigger Mac. But then we’d need another Mac around for you to be bigger than. Otherwise it won’t make any sense. Do you have any other brothers who are also named Mac? I have a sister named Maude who just showed up one day and…”

And she went on like this. Mac tuned her out, trying to think, which the pangs in his stomach made harder. Two marathon sex sessions took it out of a stallion, so he supposed now he was semi-decent, it was safe to start thinking about food.

As if in agreement, his stomach growled even louder. Pinkie stopped and giggled. “I guess it wasn’t a dragon after all. Big Mac, do you want to come to sugarcube corner and get something to eat?”

He sighed gratefully. “Eeyup”.

Still grinning, she grabbed his hand and pulled him through the streets towards the giant frosted gingerbread house.

The door opened, the bell tinkling to announce their presence. “It's okay, Mr. and Mrs. Cake took the twins out for the day, and told me to just watch things. But then I got bored and decided to go looking for you.”

Mac was barely paying attention, but that still caught his ear. He pulled up chair in front of a table decorated with pastries, and grabbed a succulent looking loaf of bread. “Err, Pinkie, whatya mean go lookin’ fer me?”

“Oh, that. Well, I wasn’t looking for you, just for someone who turned out to be you. I found you ‘cause of my Pinkie sense. See, when my nose gets twitchy, it means that there’s someone in Ponyville having a bad day.”

He’d seen enough of this foolishness of Pinkie’s around town, so he decided to humour the girl. “Eeyup.” he managed, in between bites of a large croissant.

“And when my left ear gets flippy, it means that they must be near Twilight's house.”

“Eeyup” He took a large slice of delicious looking iced strawberry cake, and decided to dig in.

“And when my pussy starts gushing like rainbow falls, that tells me there’s a big old cock out there waiting for me.”

Mac nearly choked on a mouthful of cake. He coughed violently, trying to regain his ability to breath. He stared at her open-mouthed, not believing what he had heard her say. “Wh-whu-”

“Oh no, you dropped your bit of cake. That's not good, you’re supposed to put the cake in your mouth, not on your body, silly. Unless you want to get in the cake, but you’re supposed to get in a whole cake, not just put bits of cake on you! But I bet you’re a bit too big to get into any of our cakes, you’ve got too many big muscles to ever manage to fit it all in. But I guess that if you’re in a cake and supposed to come out, then all the people who ordered it want you to have a big dick, with all those muscles, and you being so handsome too.” She gasped loudly. “Mac! I just had a totally super brilliant idea! Why don't I make you into the cake, that way you can easily fit!”

Mac continued to stare at her open-mouthed. Everything his ears and eyes told him was clashing with what he knew. He must be mishearing her, this was Pinkie Pie, one of the most innocent and naive ponies around, she couldn’t possibly be saying what he thought she was.

“Pinkie, I...I’m not sure if ah heard…”

He never managed to finish that sentence because she grabbed his hand and with an almost iron gripimpossible strength, dragged him through the shop, through the bakery, to a second, smaller kitchen in the back. “This is where Mrs. Cake makes all the cakes for those special mares only parties, so I figure I should decorate you in here since you’re going to be a cake.”

He pulled himself free of her grasp. “Pinkie, what in tarnation do ya think yer doin’?”

“We’re making a cake, silly.” She grabbed an icing bag and dipped her finger in the mixture, and licked it. “Hmm, that's so deliciouserrific. We have definitely gotta try that.” She turned back to him. “Now just take off those pants I gave you. I don’t want the special magic emergency pants I had Rarity make to get cake on them, or I’d need to use some of my emergency magic pants cake stain remover, and it’d just be silly if I had something like that laying around.”

Mac simply couldn’t follow what Pinkie was talking about and felt inclined to just give up and do what she told him, but he was still afraid of traumatizing the poor girl. “Pinkie, Ah don’t know if ya’ll understand what…”

She gave an exasperated sigh. “Geez, Big Mac, what's the big deal? It's just getting naked. Grown ups get naked with each other all the time. You’ve got a cock, just like other stallions I’ve slept with. What, you thought I’d never had sex before? Geez, and people think I’m naive.”

So she at least knew what she was saying. Still, the line between an ordinary stallions equipment and Macs member was like between a seedling and a fully grown redwood.

“Err, Pinkie, even if y’all have seen other stallions, err, stallion-parts-”

Pinkie cut him off by bursting into laughter, almost doubling over the steel table.

“Gosh, Big Mac, that's the silliest way I’ve ever heard someone talk about a cock. C’mon, just say it. It's fun to say. Cock cock cock, cock cockcockcockcockcock-” Mac shoved a hand over her mouth.

“Alright, fine Pinkie. Ya’ll might have seen other stallions cocks, but mine is a might bit bigger’n most stallions.”

Her grin widened. “Is that so?” Before Mac could react, she darted between his legs and pulled the waist of Macs pants to the floor, the thick stalk swung upward wildly and barely missed her.

The pair were stunned, Mac by her brazenness, Pinkie by his hugeness.

“Oh...my...GOSH! That's the most super-duper huge schlong I’ve ever seen. I used to think my toys were big, but this has got to be the biggest cock in the whole of Equestria.”

Mac felt the heat radiate from his cheeks as they turned even redder. He was beginning to like hearing mares talk about the size of his cock like that. Somehow, hearing Pinkie say it in such an excited tone didn’t make him feel like a freak, it only made him feel better - his fat meatstick throbbing with arousal, coming eye to eye with Pinkie.

She reached out without hesitation, grabbing at the fat swollen head, stroking and caressing it lovingly, skillfully. Celestia, how big of a cock could this mare wrangle?!!?

“Mmmm. Hello, my brand new big, strong, handsome friend.” She leaned in and kissed him on the slit, savoring the taste of his massive organ, as well as the hints of her friends juices. “You and I are gonna be the very best of friends, I can tell.”

Inside Big Mac there was a war of feelings. She was doing just as Twilight did, addressing his cock as if it were some separate creature to him, as if only her and it were alone in the room and Big Mac wasn’t even there. His feelings were still raw after the way that Twilight had acted before, and now Pinkie’s words just hit his nerve harder.

All of that just seemed to be swallowed up as he tilted his head back and groaned in pure pleasure at the way Pinkie rolled his fat head in her palms with unbelievable finesse and skill. His body reacted as well, his slit spurting out a jet of pre-cum, knocking Pinkie slightly back with force and soaking her clothes.

Without missing a beat she rolled her now sticky and soaking top over her head, and shimmied out of her skirt, leaving her as naked as he was.

She looked down at her own body, then up to Mac standing there gloriously nude, and exaggeratedly slapped at her forehead. “Whoops. Almost forgot” She said as she reached out towards his chest.

“Pinkie, what in tarnation are ya doin?” Mac grabbed her hand as she mewled in disappointment.

“Silly billy. I may be a size queen, but I don’t have a death wish. I’m gonna need to touch your amulet to get all big n’ busty n’ sexy.”

Mac snorted.

“What, did yer Pinkie sense tell ya that it's a magic amulet?”

She giggled. “No, Silly. I was watching it change Fluttershy, Twilight and my sister, Marble. I’ve been watching you put on a super duper show all day, but now I want to play too.”

Mac was so shocked he relaxed his grip, and Pinkie lunged forward, making contact with the gem.

Where Fluttershy and Marble had changed all at once, and Twilight had felt the change flow through her, Pinkie seemed to explode outwards, every part of her surging outward then receding.

Her already poofy mane seemed to poof up twice as big as before, as her mane went from framing her head to running to the floor, before snapping back to hang to her ass. Her pudgy waist snapped inwards, almost grotesquely thin, before it flowed back out to a thin hourglass figure.

A look aided by her breasts and butt. Her tits swelled larger and larger, the modest B cups becoming D’s, F’s, G’s, before running up to and eclipsing Z cups. The apron she was wearing strained and creaked as it was pushed further outwards. Below, her pelvis surged outwards to a pair of birthing hips that could actually take his rod, and an ass that was the perfect plumpness for spanking. But these parts stayed precisely put, rather than receding.

She reeled back from him, the energy too much for her, flopping onto one of the counters across the wall, giving Mac a perfect look at her heart shaped pink ass, and her dripping, tight, inviting pussy. As her boobs hit the cold steel, she squealed at the sensation, arching her back and tensing her shoulders as orgasm racked her body.

“Oh, Celestia, this feels so superawesomazing. I feel tingly and ripply and gushing all over the place. I never even knew you could feel this good when you weren’t eating. Speaking of.” her eyes looked hungrily at Mac’s length, still laying on the table, its weight causing the stainless steel to strain as she licked her lips noisily. “I can’t wait to taste that tasty bit of cock right now.”

Her hand reached out, but Mac hefted his cock up to his chest, out of her reach.

“Oh c’mon. I have just got to try that thing. Please?” She fixed him with a wide eyed pleading innocent stare, a jarring contrast to the pornstar body she new possessed. “You can’t tell me you don’t want to stuff this inside me”

“No, Pinkie!” Mac snapped. “I’m tired of y’all treatin’ me like Ah’m just some walkin’ stand for mah cock, and y’all not carin’ about me!”

He knew he shouldn’t shout like that, but these feelings had been broiling in him for hours, and he couldn’t stand being reduced like that anymore.

Her eyes shifted from his log, to his face, and then in a blur she wrapped her arms around his front, her grip being too small to get all around the muscles of his torso. She squeezed as hard as she could.

“It's alright, Big Mac. Of course I care about you. I care about you a lot.”

He felt his heartbeat quicken. “Y-ya do?”

“Of course I do, silly.” Standing on her tiptoes, she hopped to manage to peck his cheek, her lips feeling hot and wet on his skin. “I care about you as much as I do about everyone in Ponyville.”

His heart dropped again, his elation snuffed out. “Oh” he replied gloomily.

“Well, what's wrong with that? I care about you, don’t I? I want to make you happy”

“But you don’t love me. I ain’t your special somepony”

“I like you. You like me. Why does it need to be love for us to make each other feel good? Maybe it doesn’t go deeper than that, but why does it need to. It's like planning a party - does it matter that I do one for somepony else later, or if they get a party from somepony else? No, it's just good that they enjoy my party while it’s happening.”

Her soft hand brushed his face, holding his cheek. “It's not hurting anyone. You want this, I want this. We NEED this.”

Mac huffed at her. “So what about tomorrow? What about the future? There’s nowhere for this - for us - to go beyond fuckin’, whats the point?”

“Tomorrow is something Future Pinkie will think about. But I think future Pinkie is also gonna really like your big cock as well. I'm sure if she and I ever met you at the same time, we'd end up double teaming you.

But who cares what future Pinkie and future Big Mac do, why does that need to matter to us? Sex feels good, and sex with you will feel super-duper good, so why does it matter if we don’t want to feel good anymore later?”

Mac dropped his gaze. So just sex, with nothing else afterwards? Would it really be so bad? His libido was urging him to give in and feel the warm embrace of her inner fucktunnel around his monster member. That feeling of emptiness inside was ebbing away from the power of her words. Maybe it wouldn’t be so bad.

He relented, letting go of his cock. Falling under its own weight, it slammed onto the steel table, leaving a dong-shaped dent running more than half the length.

Pinkie squealed with glee. No further words were needed. She was on him with ravenous zeal, moaning as she licked all over his head. She pulled back, closing her eyes and savoring the flavor.

“Mmmm. So that's what Twilight, Fluttershy and Marble taste like. I should have waited til later and gotten your yummy cock even yummier.”

“Although, I think I know what would make it yummier than yummier.” She reached towards the bench and grabbed the bag of frosting she had set aside before. “I sure hope we’ll have enough to cover all of it.” She giggled. She pressed the nozzle against his hard, unyielding flesh, her skilled hands pumping out thick ribbons of icing. She made patterns along his meat-stick, leaving thick, tall peaks of the stuff on his two heavy, bloated testes before pulling the last few dregs out as she finished the far side.

Mac knew he should be horrified, at being objectified like this, decorated like he was just a piece of food. But the heat in his blood was beginning to rise, and he couldn’t deny the perverse allure of the way Pinkie was decorating his cock like it was the most scrumptious morsel on earth. As she squeezed and squeezed the bag, she finally gave up, realising there was no more.

“Holy moly, Big Mac. That was all the icing we needed for a week and it was all used on your big old dick.” As she frowned and looked between the bag and his cock, she started beaming again. “Worth it! This looks like a cake fit for Celestia!”

There was a loud bang as his rod lept up with a pulse of fresh arousal.

“Ooh, does someone have a secret cru-u-ush? Big Mac, do you looove Princess Celestia?”

“N-no!” Big mac managed to choke out as his schlong was jerking up and down, foiling his attempt to lie weakly.

“Oooh, you do!” Pinkie dropped her voice to a whisper. “Why, I bet you think all the time about Celestia, and….Luna!” He groaned, his knees almost giving way as another huge jet of pre erupted from his cock, coating all cakes still on the table with a thick, syrupy, clear layer.

She ran a hand along the curve of her breasts, savoring the sensation, her pout turning to a wide smile. "Mm, Big Mac, just look how huge n' sexy I am now So much better than I was before. My boobies are even bigger than any of the princesses. Oooh, can you imagine what they'd look like if you used that magic necklace on them?” She fluttered her lashes at him, fixing him with enticing bedroom eyes, and his cock leapt and lurched harder than before.

“Ooh, you like that don’t you, you naughty colt? Her big boobies getting even bigger, big enough just to wrap around aaaaaalll of your big fat cock.... mmm, I bet any mare would look just awesometastic if you used that magic thingy on them.” She giggled. “And whoever you use it on, I know she’d just love her new, hot body!”

He couldn’t admit to that, it was blasphemy. To lust after the princesses, to view two so pure so impurely, it was so wrong, everypony knew that. Pinkie, however, just giggled. “It's okay, Big Mac, I won’t tell anyone. I Pinkie promise.”

“In fact, since you told me about your crush, I’ll tell you I have a crush on somebody.” She looked side to side, then leaned in and whispered in his ear. “I don’t know his name!” She leaned back out. “Please don’t tell him, will you? Pinkie Promise!”

“Pinkie, how can y’all have a crush on somepony if ya don’t even know his name?”

She giggled. “I didn’t say he was a pony, silly billy. When I was back on my parents rock farm, I was playing near the abandoned dragons nest, when I found it wasn't abandoned after all! A new dragon family had moved in - a dragon, and his girlfriend, and his girlfriend, and his girlfriend, and his girlfriend, and his girlfriend, and all his other girlfriends. I hid so they couldn’t see me, but I couldn’t NOT see them. This dragon was sooo handsome, and sooo strong, and extra sooo HUNG! I watched him just put his cock in each of their pussies, one after the other, making them cum over and over, all day and nearly all night til they were done. When I went home, I thought about how big and meaty and big and strong and BIG he was, and that night when I went home, I touched myself for the first time just thinking of him! I never knew who he was, but I’ve thought about him ever since. Well,” she deliberately mashed her tits to his chest through the aprons thin material, her hand tracing one extra thick vein running up his shaft as her other disappeared under her apron, her fingers kicking insider her wet, tight pussy “Until now.”

He felt that heat begin to rise, and couldn’t help but feel his ego stroked. “So, I’m more handsome than this dragon?”

“Mmm, so much more handsome!” She groaned as she kissed him on the cheek.

“And stronger?” He curled his arm, making his bicep swell.

“Mmm, so much stronger!” She began to pant as she kissed his biceps, her lips hanging on his flesh as she felt chills go through her body.

“And more hung?”

“Mmmac, you are so so SO much more hung than him!” She groaned as he heard a light splash - without even touching her, he’d been able to make her cum. With grace Mac would have thought impossible for a body as generous as hers, she slipped onto the table, laying on her back, with her head leaning over the side. “So let me give your cock the deep, long kiss it deserves!”

She leaned her head back, her plump dick sucking lips forming a perfect O around the air as she waited for Mac to use her.

The erotic charge in the air took hold of Mac. He hefted his cock up off the table, angling it down to Pinkie’s lips. The mare kissed his cocks slit hard, her hungry mouth trying to draw him in further and further.

Mac was about to shove before a tiny voice inside him cried stop. He was too big for her, he’d hurt her if he tried to force it.

Another voice forced his reason and morality down. She begged for it, he was just giving the little slut what she wanted.

She didn’t know what she was getting into, he could hurt her….

Twilight, Fluttershy and Marble hadn’t been hurt, they’d loved every second of it!

That was different, the amulet had changed their bodies. Her mouth wouldn’t be able to take it...

Pinkie couldn’t see these emotions playing out on his face, she was instead staring amazed at his fat, churning cum-orbs, almost shuddering as they made more piping hot jizz just for her hungry mouth. Still, she noticed Mac wasn’t pushing. Not willing to break contact with this wonderful cock long enough to ask him why, she decided to take matters into her own hands - or rather, other body parts.

As an internal struggle raged within Mac, he finally felt something, soft, wet and strong, creeping along his massive length. He looked down, and saw that Pinkie's tongue extended from past her lips, past his cockhead, further, and further, until it reached around under his length, around his sack, and was trying to pull him closer to her mouth.

The voice inside him yelled in triumph as he began to push, slowly, inch after inch of his pole entering past Pinkies lip’s. Beneath him, she was calm, even as he started to push harder against her. She could eat a cake three times the size of her body, this was nothing. Yet, a part of her could not deny that this cock was different than anything she’d ever had before - even all those monster dildos she’d broken with her over-eager libido couldn’t hold a candle to Mac's cock. She relaxed her jaw, letting more of his broad, fat head into her mouth, as her tongue doubled back to lick the parts of his rod that hadn’t yet passed her lips.

With a wet, sticky pop, her lips passed the ridge of his helmet, his stance stumbling as the sudden drop in resistance made him ram a few more inches in quickly, forcing him into her throat. Below him, Pinkie squealed, her fists banging against the steel table. Horrified at what he might have done, Mac pulled his hips back, pulling his cock out, letting the poor mare come up for air.

As the head passed her lips, Pinkie stared up at Mac. “What’d you do that for?”

“Well, ah-Ah mean, you -Ah - Pinkie, you screamed! I thought ya was chokin’ down there.”

She sighed loudly, rolling her eyes. “I know how to breath, Big Mac, I’m fine. C’mon, I can take it. And I wasn’t screaming, I was having a squishy shaky yummy cum because of how big your big ol’ cock is.” She reached up and brought the drool covered monster head closer to her. “See? It’s head is nearly as big as my head. How could I not cum, sucking on such a superawesomeamazing dick?”

He watched as a fat bulge moved past her jaw, down her throat, before being hidden beneath the coarse white fabric of her apron. As he got deeper, though, the fabric strained, tore, then seemed to explode around her expanding chest as his cock puffed her chest out more and more with his girth. Pinkie moaned and gurgled appreciatively as the sight of her erotically changed nude body made Mac’ organ pulse with pre again, shooting a jet of it straight into her belly.

Mac was left staring at the true enormity of her tits for the first time. The apron struggling to contain them had been arousing, but seeing them naked before him was so much better. Her dinner plate sized areolae and fist sized nipples were a different, redder, darker shade of pink than the rest of her. They looked delicious. Mac bent at his hips, trying to reach out for them, but his length was still too much - she remained just out of his reach.

Pinkie felt the jet of delicious pre hitting her stomach with its heat, the sheer volume filling her tummy well. However, she was still hungry - starving, for more cock, and more cum. The length of her tongue went wild along Mac’s pole, slithering along hard, protruding veins, licking the vast expanse of his testes, lapping at the creamy icing coating his delicious meal of a cock. She wanted all of him, and wanted him to know it.

Mac was like a dog straining at its leash, a delicious plate of food just out of its reach. He pushed harder, more of his titanic cock going past the pink pony’s piehole, feeding her two feet of cock at this. Her body wriggled and writhed before him, her legs spasming and shaking as the sheer pleasure of sucking his cock was like electricity running across her body.

Then she began to suck.

Her mouth was like a black hole of pleasure as Mac lost whatever illusion of control he had, Pinkie’s hungry throat just sucking more and more of his cock in like a fat sausage. Should the Cakes come home to find their surrogate daughter getting a nearly five foot cock shoved down her throat, they might think Pinkie was being face fucked, but the truth was that the pink mare was in total command of the situation.

The tight, hungry pressure of her suction sent shivers along Mac’s organ, tingling and rippling across it, providing a delightful massage. The feeling of her hot throat around his rod like a second skin was making him delirious. His hips went out of control, bucking and fucking more erratically, letting Pinkie swallow more and more length. His cock drooled a continuous stream of his pre into her rapidly swelling stomach, her now-tight belly beginning to bulge outwards as she swallowed more of his prejaculate.

He kept at it as more and more of his root disappeared down her throat ‘til Mac could swear that he had fit more cock inside her than could possibly fit in her body. The thought was interrupted as he felt her lips press against his pelvis. Every inch of his pillar of masculinity was lodged deep in Pinkie's throat.

Below him, Pinkie was over the moon. His big, swinging sack nestled in her poofy mane, and her nose pressed right up to his cumfactories, leaving her breathing deep of his pure, undiluted musk. Even on a mare with the utmost restraint, such a raw, primal smell would send them into instant heat, filling their heads with images of the handsome super-stallion who emitted it. With a gal already crazy about big cocks like Pinkie, it just sent her into an almost trance like state, cumming with every noseful of air she took in. Mac eclipsed the thought of any other cock even possible - he was the only male for her now. She moaned in a continuous hum of orgasm around the meat lodged in her throat.

The feeling of her tight throat vibrating around his entire organ was pushing him over the edge. Realising what was about to happen, he tried to pull out, but Pinkie’s suction kept him lodged within her, and her arms wrapped around his thighs. He couldn’t see her pleading eyes, but the message was clear - she wanted all of his cum deep, deep in her stomach, filling her up like nothing else could.

The pleasure was too much for him. He grunted, groaned, snarled and snorted, the primal stallion within him breaking through his soft, gentle personality, as he slammed into her throat hard. From where she was stuck, she saw, smelt and heard up close how his balls clenched and shuddered; inside, release valves opened and let loose a torrent of cum. She felt her throat bulge out as his impossible girth got even thicker, a stream of his jizz swelling his organ out wider as it forced its way through. It went past her teeth, past her tonsils, down her throat, until it exploded out directly into her stomach. It was like she had an entire waterfall in her stomach as Mac’s cum gushed out into her in thick burst after thick burst. Her eyes crossed, his pendulous sack blurring before her eyes as she nearly blacked out just from the feeling.

The orgasm shook Mac’s body, tremors wracking his strong body, as his cock jackhammered into Pinkie, the motion only whipping up the ball-batter in her stomach into a frothy churn. Her stomach was ballooning out as her seemingly endless belly room took every single drop of his cum, with not a single drop managing to get free. Her body was pushed to new heights, with her belly swelling larger and larger, growing to the size of, and then surpassing, her breasts.

As the intensity of his orgasm dropped, Mac’s torrent became a stream, as Pinkie let his cock free from her hungry sucking throat, right up til she felt his cockhead pop into her mouth. Now, she could taste his salty, strong, manly cum. She gulped down more from his after trickles than any dozen other stallions could make in a lifetime, until his organ finally ran dry, and she let his cockhead free with a pop.

She licked at her lips, slowly running across her plump, sensitive, kisser, then opened her mouth wide before Mac to show him her cum free tongue and mouth. “All gone. And I was right, it DID taste superawesomazing.” She lifted a hand to her belly, rubbing her fat, wide, distended gut with her perfectly trim arms. “Geez, Big Mac, look at what all that yummy cummy has done to my tummy! I must look super-pregnant!”

Macs cock gave another audible bang as it lurched up and fell on the stainless steel table, another fresh throb of arousal making it dance. She flinched at feeling and hearing the impact, sliding back and turning with unbelievable grace given how her body was stuffed. When she saw what had caused the noise, she got a devilish grin.

“Oooh, Big Mac, do you have another seeecret? Do you like the idea of me being filled up with your little foals?”

The blood-pumping action and sheer awesome pleasure of Pinkie’s sucking had done a lot to quell his feelings of shame. Mac laid a hand beside hers on her stomach, feeling his cum slosh within her distended belly, looked into her eyes, and gave her a breathy “Eeyup”.

“Your thick, yummy jizz tasted so manly, I bet I’d get pregnant for sure. C’mon, I love babies, Big Mac, I can’t wait to have all of your big, fat cock filling me up to my womb, feeling your babies in my big, bloated belly, feeding them with my huge, milky tits. “ She laid back and spread her legs wide, holding her belly back with both hands, as she presented her dripping, tight snatch for Big Mac to fuck.

Mac was enthralled, looking at her marehood. Her tight, glistening vulva, her labial lips just barely apart, like a flower, preparing to bloom right for him. Her innermost secret part was a darker shade of pink than the rest of her, with her clit poking out just at the crest of her lips, an almost white reddish-pink jewel. He ran a strong finger along her opening, collecting her sticky, hot juices, and brought them to his lips. He tasted it. Sweet, tangy, delicious. He would have got on his knees and feasted on her dripping quim, but from her impatient moans, he could tell Pinkie wasn’t interested in what his tongue could do, she wanted his third leg.

He gripped his organ at the midpoint with both hands, maneuvering the unruly beast like a heavy piece of equipment ‘til he could line it up with her quivering opening. He rubbed the head against her lips and pushed.

Pinkie arched her back, seeing spots before her eyes, as she screamed so loud Mac thought the neighbors would hear. Like a gentlestallion, he resisted the urge to slam as much of his pole into her as possible. Instead, he let her ride out her first big climax as her sensitive walls were speared by his massive cock. Her orgasm stretched, and her screams kept coming - if he didn’t know better he’d swear her lungs swelled as much as her chest - but eventually, her spasming wet tunnel returned to its uniform sucking tightness. He smiled down at her as she regained her composure.

“Ya-”

“FUCK ME!” She practically screamed.

Mac didn’t need to be asked twice, as his hips began a steady pistoning rhythm, forcing more and more cock into her buttery smooth snatch with every stroke. It was too intense for her to even talk, her mind going blank, as she was reduced to biting her plump lip, whimpering, moaning, and climaxing again, and again, and again. Her hands tried to reach for his body, to run her fingers along every muscle of his god-like body, but her swollen stomach kept him beyond her reach. So her hands went behind her head, clutching to the table with white knuckle intensity.

Mac claimed more and more of her pussy slowly, as inch by inch forced its way into her tight wet slit. As her pussylips finally passed his crown, she squealed. “Fuck-...fuck...fuck!” She managed as she gasped for air. “No...pony….ever...this...deep!” Mac had to grin. So even with a size queen like Pinkie hunting down the biggest studs she could find, none of them had ever had a cock that was as big as just the head of his mighty organ. He felt the news tickle his ego delightfully before he reminded himself there was a sexy seductress beneath him begging for his cum, and he would be quite rude if he didn’t deliver.

With his crown past her hungry, tight lips, he applied more pressure, feeding inch after inch into her snatch, ‘til he had a third inside her. Then, he pulled back, leaving only his cockhead inside her - any further and he simply couldn’t pull it out. Mac squared his stance, braced his hips, and with well practised technique, he jabbed forward - his pole driving through her tightness, claiming virgin territory, and sending every nerve it touched into orbit. She squealed as she came. He grabbed her legs, hooking her knees around his forearms to better pull her onto him, and thrust again.

During the passing hours of intense sexual intercourse, her stomach slimmed down back to it's perfect trim thinness she began her new life with. Processing all of his god given cum and using it to somehow make her pillowy ass, childbearing hips, and mountainous tits even larger than they had previously been. Mac certainly noticed and made his approval clear by squeezing each one of her worldly assets with both hands, eagerly exploring every inch of his willing slut. Another unexpected effect to her stomach returning to its flat form was she could now not only feel his cock stretching her insides with every thrust, but now she could actually see the giant pole shaped bulge that stretched the skin of her abdomen outward. She swore she could see his veins twitching through her pink coat and like a pony possessed, she reached one of her hands down and stroked the pole shaped bulge in tandem with his powerful thrusts to give him that much more pleasure.

As her stomach slimmed back to the flat board the amulet had granted her, Mac could finally reach her fat, fist-sozed nippled, groping them passionately. Her tits, finally in his grasp, responded to his touch with a jet of sweet smelling pink liquid. Mac lifted a hand to his lips and tasted it. Strawberry milk, so sweet, it drove him wild. He jabbed another foot into her, getting close enough to her that he could bring his mouth around her huge tits, sucking at the outpouring of sweet nectar, as Pinkie’s moans hit a new octave.

He licked, sucked, nipped and kissed her huge breasts like a stallion possessed, his tongue growing, lengthening, almost like Pinkie’s, as he tried to taste more, more, more of her sweet, abundant titflesh. Her breasts started spraying her sweet strawberry milk wildly under his touch while her body was wracked by multiple orgasms, her sweetness shooting all over the bakery, drenching the cakes, her body, and Big Mac.

The taste was unreal to Mac, driving him to new heights, new passions. It was different than Twilight's magic, but gave him that same feeling of energy, pushing his godly body to new heights. With every thrust of his hips forward, the table beneath them gave a shudder, straining against the rivets keeping it bolted to the floor. His hips flew back, then rammed forward, his sack swinging like a wrecking ball, ‘til it slammed into the steel and the entire thing buckled, falling to the floor in a heap. Pinkie didn’t even drop, her entire weight held up by the hard cock inside her. The lack of the cool sterilized steel beneath her cushy ass did mean she lost grounding, and was just bounced madly with each of Mac’s thrusts. With each ferocious pounding, she was sent flying, riding up and down his pole like the slide on a trombone. Only the sheer fat width of his cockhead was keeping her from popping off his knob and being sent flying.

With no table to brace herself with, she was absorbing the full impact of every one of his thrusts, and this was sending her enormous melons flying, bouncing high enough to fill her entire view - not that she noticed. Her world was his cock and the pleasure it was giving her.

As he reached the four foot mark, Mac found a barrier that he would not bulge. Pinkie’s womb, the tiny entrance kissing at his cockhead, but unwilling to take his size within. The pure sensation of four feet of his cock within her being massaged wetly, and her womb kissing his very tip within her was driving him over the edge. The realisation of being so close to her core, triggered something in his loins, as he felt the first mighty stirrings of his orgasm.

“YA WANT MY CUM?” He roared, snorting with mad passion.

“YES! PLEASE! GIVE IT TO ME, KNOCK ME UP, MAKE ME A MOMMY!”

“THEN TAKE IT ALLLLL!” With all his strength, he lodged himself fully inside her, every inch of his impossibly long megacock snug inside her body, his cockhead ramming into her womb. No protection, no missing, he was about to hose her eggs with his spunk. His balls tensed, and he felt his hips forced back in recoil as his jizz shot out like a cannon into her womb. They both watched in lust and awe as her stomach bulged out with each shot, her abdomen swelling and sloshing around his thick load, as she cried out in joy at feeling his cock pumping life deep into her womb.

He was a stallion possessed, ramming into her with three foot strokes. Pinkie could feel his pork sword invading her womb, again and again, over and over. Each thrust unloaded more fertile, baby giving cum. She wailed with pleasure as her mane poofed up even more, thick bushy curls growing longer and thicker, growing to the floor and out, thicker, denser, enough for her to lay back on.

She fell back into her forest of soft hair, Mac almost laying on top of her, never once slowing his thrusts. Mac pulled her head towards him, and they kissed, hard, all their passion and lust expressed with this one act. Mac’s lengthened tongue met Pinkie’s already long one. They were like two living creatures in total passionate love as they wrestled between the two ponies mouths. Mac was ferocious and dominant, invading Pinkie's mouth, nearly skull-fucking her with his tongue. Pinkie couldn’t even respond, just letting Mac do as he wished with her body.

This feeling of being kissed so hard, so passionately, with so much raw power, triggered another cluster of multiple orgasms racking through Pinkie's body, joining the dozens in progress all over her body. Every nerve was being wracked by orgasms - it felt like she was one big cunt, that Big Mac was expertly making love to, and she was feeling his skill everywhere. Finally, their mouths were pushed apart as her swelling stomach simply got too great for them to be joined anymore. Mac gave one, two, three more thrusts, then his cum explosion finally ended. He pulled out his still hard cock, soaked in her juices. Her tight snatch snapped almost closed as his cock pulled out, her body not wanting to relinquish a drop of his cum.

“Best...fuck...ever..” She weakly moaned, before she could take no more, and simply passed out.

Mac left her sleeping on her hugely poofed mane, now big enough to support her weight. He struggled to his feet, the better to survey his handiwork. He laid a hand on her swollen belly. He half expected to feel a kick, but of course there was nothing. Wouldn’t feel anything like that just moments after sex, even with how much he came.

Actually, as the memories finally connected in his skull, wouldn’t feel anything in her belly anyway. He remembered the spell Twilight had cast on his balls, stopping all his little swimmers in their tracks. No matter how much he came, no way he could impregnate a mare. Even one like Pinkie, who had seemed over the moon at the idea of being a mommy.

Still, no reason he couldn’t come back after he’d had Twilight remove the spell, give the pink mare another round of heaven and the foals she wanted. Or bring Pinkie with him to Twilight, do it right there in the crystal palace. Along with Twi, who’d probably beg to have him fuck her and impregnate her as well. And Fluttershy and Marble, can’t leave them out. He’d breed all four of them good and proper, and then, start changing and breeding every other fertile mare in Ponyville….

Wait, what? What was wrong with him? Where did these ideas keep coming from? How could he even think like that. Just going around changing any mare he felt like, it wasn't right. And as for breeding them….He wasn’t ready to be a father, he couldn’t provide a future, he didn’t know enough about the world to raise even one kid right, and here he was somehow daydreaming about having kids with the four mares he’d roped into this mess, and more besides that? This wasn’t like him.

Sex is one thing, but a child - that was forever, it can’t be just something he decided to walk away from because he got bored or didn’t feel anything for their momma.
Yeah...yeah...sex is one thing. Pinkie had been kinda right about that. Sex, without any real feelings, just two bodies using each other for their own pleasure - it hadn’t been so bad. It had felt great having his cock buried all the way inside her, and the things she could do with her tongue had blown him away. He’d have kicked himself if he passed this experience up.

So why did he feel so cold inside now? Why did it feel like there was a hole in his chest? All that passion, that feeling, that pure energy he’d felt just a little while ago with Pinkie, it felt like it was all gone. Why did looking at her sleeping, covered in sweat and her own milk, make him want to start crying, and never stop until he died?

He hadn’t felt that way when he was having sex. As soon as she started lathering his cock up like that, all those thoughts and feelings had gone away. So yeah, Pinkie was right about needing sex without feelings, because the feelings he was experiencing now felt like death.

Was sex the answer? Just mindless, consequence free rutting to drown out this empty feeling?

Did he really have any other option?

He turned, his cocktip decapitating an errant wedding cake. Welp, if he was leaving, he wouldn’t make the same mistake twice. He hiked up the pants Pinkie had given him, the satiny material enveloping his monster easily. Rarity had done wonders with this material, but now the things were covered in sweat, milk, and cake. He’d have to swing by her place to get a couple fresh pairs if he intended to regularly keep going out in public.

He strolled to the front door, and reached for the knob, when a weak voice came from the back kitchen.

“Wait….I….I...want...more….”

Mac grinned. Well, he’d felt great fucking Pinkie the first time. He added two more hours to the 'closed til' sign, locked the door, dropped his pants, and ran back to Pinkies waiting arms.
