Soul's Desire

Big Macintosh stretched his broad muscle arms as his back off of the bed. A deep yawned escaped his mouth as his eyes began to open. With a smile on his face, he lifted himself up off the bed, but stopped as a memory from last night entered his mind.

“I had the dream again.” he said as his smile was replaced with look of concern. He put his hand over his head and rubbed his temple. “Sweet Celestia why won’t they go way.”

Why do I keep having that damn dream. He thought to himself as he put his hands over his head. After a minute of pondering, he shook his and decided to ignore the nervous feeling in his gut.

They’ll go away eventually. I Know they will. I just hope I don’t have a problem. How many other stallions have dreams like that?

For almost a month now he had several dreams involving himself, each one more vivid than the last. They were all different for the most part but they all shared one common theme. He had no idea what it meant.

In the first few dreams, he imagined himself being taller, bulkier, and stronger. He would do work on the farm as if nothing was amiss, occasionally ripping articles of clothing as he did so. He would often feel a strain in his pants, as his pumpkin sized dick bulged in his pants and brushed against his legs.

With each passing dream his body got larger while his surroundings got more and more surreal. His body went from being as tall as the apple trees to being able to carry two of them with one hand alone then to being larger than the entire barnhouse. All the while his muscles ballooned outward in size and strength and his dick and grew in both volume and length.

Last night, he had gotten so big that he was able to put the entire planet into crevices of his immeasurable sized pecs.

Big Mac put his hand to his forehead as sweat dripped off his brow.

Why I keep having these dream about being bigger? Aren't I big enough? Why in the name of Celestia do I find these dreams so… so…

With shame, the red stallion sighed as he continued his line of thought.

Why do these dreams make me feel so good?

Even without looking Big Mac could tell that he ejaculated in his boxers again. The dampness Mac felt between his legs and was a perfect representation of his self loathing.

If his family ever found out about this, hell if any sane pony in their right mind knew how happy these dreams made him feel, they would never look at him the same way again. Hell, for all he knew, he might have some weird psychological conditions.

He got up from his bed and strolled over to his mirror at the end of the room.

“This isn’t normal.” He said out loud. These thoughts should not make him happy. He shouldn't be turned on by them. Yet he was. Oh sweet Celestia, how he wished his dreams could become a reality. To caress all of existence in his bulk, to have entire worlds rest on his pecs, to shoot out a load so big that it would put out hundreds of stars in his general direction.

Yet if anyone ever knew how I really felt...

Macintosh shook his head. Deciding not to dwell on his bizarre dreams anymore he set off to start the day. He got out of bed, removed his messy boxers, cleaned the mess off of his legs, put some fresh boxers on, put on a pair blue jeans and white undershirt, and had breakfast. Afterwards, he changed his wet bed sheets with some clean ones, and head out into the orchard where Applejack was waiting for him.

As they walked he turned to look at her. Like him she was dressed in blue jeans and was wearing her favorite red checkered shirt. Here eyes were looking straight up at the sky as if she didn’t have a care in the world. Before the dreams started he himself would have looked the same.

“Well I’ll be Mac.” said Applejack has she put her hands behind her head. “It sure looks like a nice day to get some good old fashioned apple picking done.”

“Eeyup!” Big Mac groaned half-heartedly as he stared up at the bright blue sky.

Applejack stopped and put an arm on her brother’s shoulder.

“Everything ok Big Mac?” She asked with concern. “You seem kind of reluctant about work today. Now either you have an upset stomach and are trying to brush it off as nothing, or something is eating at your mind.”

Big Mac looked down with Applejack sighed. He knew there was no sense hiding anything from here. Despite being the quiet one in the family Applejack could read him better than a book.

“I’m fine,” he said with a hint of uncertainty. “I’ve just been thinking about Mama and Papa.”

Applejack stretched her hands upward to and patted her older brother on the shoulder. “Not a day goes by I don’t think about them.” she said with a compassionate smile. “I miss them so gosh darn much. I know you're not the talking type, but if you want you can talk to me about it.”

Big Mac nodded his head and continued.

“I’m just thinking why’d they add the word ‘Big to my name.” he said softly.

AppleJack tilted her head in bewilderment. “Why would you all of a sudden be thinking about that?”

Big Mac sighed and lowered his head. “Mom told me that when I was first born they named me Big Macintosh because of how large I was for a newborn foal. As I’ve gotten older my body has stayed true to this name. I’ve been one of the few stallions in Ponyville for as long as I can remember. Hell, the fact that I’ve worked on this farm all my life has helped me stay in top physical condition, though I’m nowhere near as built as that Snowflake guy. And I don’t mean to be vulgar sis, but you know how ponies always joked about my… well… you know?”

“Whoa nelly! Say no more Mac!” Applejack said as she halted him with her hands. “I know what they say about it!”

“Sorry sis!” he said drawing back his face in embarrassment. He let out a loud cough to ease the tension and continued talking. “The point I’m trying to make is that everything about me is big. I know a lot of pony parents chose names for their foals that tend to fit them perfectly, but lately I’ve had this strange thought.”

“What’s that?” ask Applejack as he leaned a little bit closer to her brother. Mac could tell from her expression that she was really curious about what he had to say. While he rather not tell her anything, telling her nothing would make him look suspicious.

He looked up at her and took a long deep breath, as if what ever he was about to say might somehow cause a magical bomb to go off. “What if my size as a foal wasn’t the only reason why Mom and Dad called me Big? What if they saw something about me that even I didn't recognize about myself?”

The orange mare shrugged, unsure of what to make of what her brother was saying.

“Could you give me a better idea of what you mean?” she asked. “Like, why else would they name you Big other than for your size.”

Big Mac gulped. He was afraid that Applejack wouldn’t leave well enough alone and he knew lying to her would only cause more problems. He took a long deep breath as he thought about how he would spill his darkest secret to his sister.

“You see AJ,” he said as he mustered the strength to confess. “Lately I’ve been have these strange dre-”

Before the he could finish his confession, a high pitched scream echoed across the orchard and startled the two siblings. They quickly turned their heads to the sound of which if seemed to be coming from the Everfree Forest.

“Mac!” Shouted Applejack said with her with her eyes staring right at him. She ran towards her brother and franticly place her hand on his shoulder. “That sounded like Zecora! We need to go see if she’s ok!”

“Eeyup!” replied Big Mac just before breaking into a sprint towards the forest. Applejack tried to catch up to him but quickly lost sight of him when he entered through the edge of the forest.

With the speed of a horse and the endurance of a rhino Mac plowed straight through fallen tree branches and bushes without it hindering his momentum. Granny always said that he should tryout for the Equestrian games, but right now all that mattered was finding the distressed zebra.

Eventually the earth pony came to an opening clearing. Zecora had been cornered into a tree by a large of pack of about seven or eight timberwolves. He figured she must have wandered into their den my mistake. No pony new the forest like she did, but he figured that didn’t make the Everfree any less dangerous.

“Oh thank goodness!” shouted Zecora. “I thought I was lost! Please help me my dearest Macintosh!”

Desperate to help his friend, Macintosh grabbed the largest stick he could find and threw himself into the fray. With his herculean strength he bashed the wooden spirits into until they were nothing but debris. One of the wolves jumped and bit Big Macs shoulder only to have it’s sappy teeth shatter into splinters from Big Macs muscular upper body. Using both his hands, he grabbed the beast by it’s legs and hurled it into another timber wolf, shattering both of them. Frightened by this hulking creature, the wolves withdrew into the forest.

“Oh Big Macintosh,” said Zecora as she hopped off the tree and began to walk towards her hero. “You came just in time. I’ll admit, your fighting skills were sublime.”

“I’m just glad I could help.” Mac said he scratched the back of his head as butterflies filled his stomach. Being as timid as he was he always got nervous around mares, especially Zecora, who only wore small pieces of loin cloth for clothing. Even through her small brown top she wore abround her ample chest her nippes were clearly visable beath the fabric. As the zebra walked closer, he could feel a stir in his loins.

“I feel must reward my saviour,” she replied as put a she put an arm around his shoulder, “For it only right to return the favour. Please come back to hut for some nice hot stew, then we can talk about what I should do.”

Big Mac cursed his horney self as improper thoughts popped into his head.

Darn it, these damn dreams are messing me up more than ever. How could I even think of doing that? It’s not how I was raised.

“I sense something is troubling you,” Zecora said as she picked up on his discomfort. “Do you perhaps not like my stew?”

Big Mac sighed as and closed his eyes before looking back at Zecora. “Your stew is the best in Equestria and you know it.” he said before lowering his head. “I just have a lot on my mind now. Been having these weird dreams lately and they’re bothering me. They're kind of strange and more than a bit sensual so I haven’t been able to talk to anypony about it.”

Zecora chuckled. “Luckily for you I’m not offended by vulgarity. If you tell me your dream I may be able to provide clarity.”

As they walked to Zecora’s hut Big Mac told her about his dreams and how ashamed and horny they made him.

“I just don’t know what’s wrong.” He said, in a jittery voice as they began to approach the door of the hut. “In my dreams I want everypony to worship my body, to flaunt my fifty foot package for the world to see, to hold a hand full of mares and put them between my abs. It’s like I want to be a symbol of male prowess and power, with the vitality, strength, and physique of a god.”

Zecora nodded as she opened the door to her hut. “And in these dreams that make you feel shame, to you long to cause other ponies pain.”

Mac sighed.

“No, in my dreams I just grow and ponies around me just expect it. I’ve fucked the inside of Canterlot Castle and put mares on the top my dick, but I’ve never hurt anypony. Even when I do get really big I somehow know where not to step. One time a few nights ago, I painted the entire planet with my dick. That time, I thought I was killing everypony, but then something weird happened. Well… weirder would be more appropriate. I could sense that not a single soul had been hurt and I beckoned them to live on my body. As I began to fill the cosmos with my bulk, girth, and jizz, I became a planet to them, one that just kept growing.”

Zecora sat down and stared at Mac. He sat down in the chair next to her, worrying that he had just lost a friend to his weirdness.

“Mac, thank you for getting this off your chest. Now there is something I must confess.”

Way to go. Now she going to label you for the freak you are. Nice going genius. Spilling out all these damn dreams to a girl. What the hell is wrong with you?

“For you see, these dreams don’t make me feel repulsed or upset...”

Big Mac opened his eyes, not expecting that answer. “Then what do they make you feel?”

Zecora smile as slowly untied the string of her top and slowly took it off, leaving her delicious striped melons exposed.

“To be honest,” she continued in a seductive tone as she put her hand in her loin cloth and began touching herself. “They make me feel wet.”

His jaw dropped in disbelief as Zecora began to take her loin cloth off with one hand while gently mastebating with the other. All the while the golden nipple rings one her black nibbles began to flop up and down as her breast jiggled up and down. As the loin cloth slid off her leg Zecora smiled playfully, her eyes falling upon the growing erections in Mac’s pants.

“Why must you look so nervous?” she asked as Big Mac as his eyes anxiously tried to look the other way. “Isn’t it your dream for your cock to be serviced?”

Zecora stood in awe at the sight. Before her stood sixteen inches of girthy cock, already at full mast. It was easily the biggest she had ever seen, almost three inches longer than the average stallion.

And to think he longs to be bigger. thought Zecora.

Not wanting to wait any longer she yaked Mac’s shirt and tossed it aside. Here tail began to sway has her eyes explored Mac's naked body. First her eyes looked up at his face, admiring his broad red shoulders and long golden mane. Straightening her head, her eyes made direct contact with his bulging pecs, his dark red nipples aligned perfectly with her eyes. Not satisfied with a single perspective Zecora put hand around Big Mac and seductively circled around him like a shark. After she was done admiring his his toned six pack, she stopped to appreciate his toned muscles much like an art critic would a sculpture. She brushed her free hand against his tail, giggling as it started to twitch in her hand.

Then at last, her eyes fell on her prize. She withdrew her hands and sat back in her chair.

“I know a way,” she said. “To make your dreams go away. But before I tell you, a favor you must do. Come lean forward with your massive dick, and let me caress it with my wet clit.”

While normally put off by such vulgarity in a normal setting, Big Mac found Zecora’s poetic seduction oh so arousing. He ran to her and pressed his lips against hers, all the while sliding his impressive pole into her totem.

He was gentle at first, slowly thrusting his girth while he fondled her mohawk and played with her ass. As the moment picked up the two of them started to get rough. With both hands he picked Zecora up and rested her butt on his knees. Zecora squealed as she he bobbed up and down on his length.

Suddenly, Big Mac lost his balance and the two were forced to bring their lovemaking to the floor of the hunt. Mac shifted to the top position and thrust hard into Zecora, who now had half of his cock inside her.

“Harder!” Zecora screamed as her hands explored his chest. The sex had only just started and already she could feel her nethers on the brink of exploding.

“Are you sure?” asked Big Mac as let out a moan. “I don’t...Oh!... want to…. OH!... hurt you! This is my first time.”

Zecora eyes widened at the idea as some pony as tall, strong, and handsome as Mac could be a virgin. Even more surprising was that he was actually doing a very decent job for an amenture. Even now he was touching her in the right spots, as he rubbed her striped back his meaty hands.

“So kind of you to show restraint,” she said as she lunged forward and pressed her boobs against his bulking pecs. “It makes me feel like I’m screwing a saint.”

Zecora and Big Mac began to chest bump each other with their assets. His pecs and her boobs pressed against each other, sending ripples through both of them. Occasionally, they would collide at just the right angle where both there nippes would touch each other. Big Mac had no idea what the two of them were even doing or if it even had a name. All he knew was this sensual chest bumping made his body tremble and Zecora apparently more so as he looked down to see that she was lactating.

“Mind if I take a sip?” Big Mac asked seductively as he leaned his head forward to slurp up Zecora's milk.

The sensation of being milked by Mac drove Zecora to an early climax and her fem juices sprayed out of her and onto the floor. With more lubricant in place, Big Mac was able to get every inch of his apple tree into her.

Now fully inside her tightened folds around his shaft, causing a sizable about of pre to droop out from the tip. Big Mac panted as he felt he was about to reach his limit, but there was no way he was going to blow his load this early. He pulled out of her and watted for his hose to calm down, cause Zecora to grunt a bit in annoyance. However her frustration quickly vanished as rendered her.

After another two minutes of bucking, Big Mac finaly got the entire sixteen inches back inside the zebra. Once fully inside, Zecora yelled something that drove him over the edge. “Indulge yourself and visualise your inner fantasy, only through experience can it become a reality!”

He imagined himself out growing the hut, lifting Zecora up on top of his cock. He imagined filling her up with so much jizz that her body would have to grow along side him just to take it all. He thought back of his dreams, all the things he wished he could do at various sizes.

But what really turned him on was Zecora’s beauty and her strange but reassuring admiration for something that once brought him shame. As he felt a tingling sensation at the top of his dick, he let out a loud holler moments before ejaculation.

“I WANT TO GROW!”

They climax in unison as Mac fired a load into Zecora that would rival any ordinary stallion. Zecora squealed as shot after shot entered her, each load bigger than the last. After five shots Mac pulled out and nuzzled her boobs with his mane.

“Thank you Zecora.” Big Mac said. “I would love for my fantasy to come true, to be prideful of myself in a way that would be pleasing to others. But even if you could, would it be right?”

Zecora pet his mane smiled at her prince. “Pride in one's body is not a sin so long as your modestest to your friends and kin. Your heart is pure, of this I’m sure. So before you go, a gift I will bestow.”

Zecora got up, took a few empty vials, and began to scoop up the leftover fluids on the floor.

“I’m not going to have drink my own…”

“Relax!” she said reassuringly. “No need for a commotion. All this nasty stuff will be absorbed in the potion. In other words, the bacteria and biomatter will be burned up by other ingredients.”

“Are you sure?” he asked, his voice started to get a little shaky. “Cause I’m really squeamish about that sorta stuff. One of my cousins told me about this one farmer who cast a spell on his dick and shot a giant load into himself. Horizontal I think his name was. Anyways, even if what you say is true, the idea of sperm in a mans own sperm in his mouth - especially mine - really freaks me out.”

Zecora sighed, as she looked at Mac as he folded his arms and began to shiver a bit, obviously very bothered by her suggestions.

“Alright.” she nodded. “If you insist, I’ll just use saliva from a tender kiss.”

She leaned forward and locked her lips with Mac. As the two ravaged each others mouths, Zecora grabbed an empty vial from the table and held it over their lips, being mindful to catch every bit of salva that slid out of the stallions mouth.

With a substitute ingredient in place she poured all the vials except for the one with Big Mac’s sperm into her cauldron. Waking from cabinet to cabinet she diligently prepared the remaining ingredients and added them into the mixture. Once everything was in the pot she turned her head back to Big Mac and gave him an apologetic smile.

“Two of the ingredients,” she said, “were love and lust. For this potion to work fluids are a must. While your seed would have worked, your saliva will do. Now with that said, I must tend to the brew.”

Zecora started to hum as she began to stir the mixture with a spoon. Mac decided he should take this time getting dressed. While getting his undershirt back on was an easy feat he found getting his underwear back on to be a challenge. Zecora was still naked, and his eyes couldn’t help but look at the zebra’s swaying as she churned the brew. The sight of her caused his dick to spring back up, forcing him to turn away and wait for it to calm down. After his pole had settled down he waited till he was fully dressed before he dared to look back at the zebra.

At last, Zecora took one final sniff of her brew and scooped it up into an empty flash.

“This potion,” she said “Is called Soul’s Desire. It will give you whatever wish you require. The potion’s power is very very old, but for it to work it’s wonder the drinker must have a heart of gold. If the potion chooses you, your dream will become reality, and you will be the pinnacle of masculinity.”

Big Mac gasped, shocked such a powerful magic could even exist. While Zecora did assure him that the pony needed to have a pure heart, the idea of a potion that could potentially do anything boggled his mind. How in Equestria did Zecora make such a potion, and why the buck was she giving it to him?

“I’m flattered Zecora,” Big mac said as he scratched the back of his head. “But are you really sure I should do this? What about my family?”

Zecora gave him a warm patient smile and kissed him on the cheek before putting the vile in his hands.

“It’s your choice, but I’m sure they will grow to accept you. Just makes sure you’re alone when you drink it if this is what you decide to do.”

As Big Mac walked out of the hut to head back to the farm he could hear the zebra’s lustful moans as she began to indulge herself once more.

The remainder of the day was hell. When Mac returned from the field Applejack was angrier than a dragon with out a horde.

“What in tarnation took you so dang long!” she yelled, puffing her cheeks. “After that talk we had about mama and papa, thought I was never going to see you again.”

Big Mac stretched out his hands to try and calm his sister down, only to have her luge for him in with her first. While he new Applejack was more fit than your average mare, he knew he could take a blow or two her. Still, he jumped backwards to avoid her blows.

“Calm down AJ!” he said just as Applejack was about to go for another swing. “I was never in any danger.” He went on to tell her about his exploits in the forest. Of course, he filtered the part about the sex and Zecora’s strange but exciting interests in his dreams. However, much like before, Applejack was as observant as ever, as she pointed a finger at the strange vile in he held in his hand.”

“I see Zecora gave you one of them fancy potions of hers.” she said with a tint of skepticism in her voice. “Mind telling me what that supposed to do.”

Dammit AJ! He thought angrily to himself. Why can’t you just let things be.

Figuring she could already sense he wasn’t being honest, he decided to respond with the safest answer that popped into his head. “It was gift for saving her life. Also, it’s private. She isn’t even a hundred percent sure if it will work. Anyways AJ, let’s just get back to work. We have alot to make up after all.”

Applejack nodded and the two of them ran towards the nearest Appletree, each one determined to work extra hard to compensate for the lost time. After an entire afternoon of work, Mac and his sister retired to the farm, had their supper, and retired to their bed.

As Big Mac put on a his night time close, he looked up at the potion he had placed on his night stand. Once he was all dress, he leaned forward and give the flask a little tap with his finger. He stroked his chin, pondering whether or not Zecora was playing some sort of cruel joke on him.

Can this thing realy do what she said it would do? Would making those odd dreams come true really make me happy, or would it only create new problems for me.

His tail swished irritably as he sat down on the bed and eyed the mixture.

Suddenly, his face lit up as a brilliant idea popped into his head.

I’ve got it! he thought as he as he felt his anxiety slowly fade. Maybe if I tell myself that what I desire most is to get rid of these dreams forever, they will go away. That would solve everything, and I wouldn’t have to become a freak force of nature.

The promise of finally having a normal night's sleep comforted him mind has he eagerly reached out and grabbed the potion and popped the cork. Just before he could raise the bottle to his lips however, ideas of godhood, growth, power, and lustful pleasure filled his mind.

“Just focus on what your really want.” He told himself. “If I made those dreams reaily, it would cause a whole mess problems for me, my family, and all of Equestria. Right now what I wan’t more than anything is to not have these anymore. I just need to focus on that and nothing else, and hopefully the potion will do the rest.”

Hesitantly he poured the liquid traveled down his throat, he silently praying Zecora didn’t slip any of his cum into the mixture. The taste was certainly estranged, like apple cider mixed with pineapple juice. It was an odd blend, but one that felt sweet as the last few drops entered his mouth.

Putting the empty vial back on his nightstand, Big Mac leaned back and let his head fall onto his pillow. At last he can be rid of those bizarre and perverted dreams forever. As he his drowsiness overtook him, couldn’t help but feel like his pajamas felt a tad tighter than usual, but he figured it was just his mind playing tricks on him.

They probably just shrunk in the wash? he told himself as his mind fell into a deep sleep, completely oblivious of the small rips that were forming around the sleeves of his pajama top.

Reality (female cum inflation warning)

After have the most average night sleep he had in weeks Big Mac awoke with a new sense of optimism. Unfortunately, when Mac opened his eyes exuberance was washed away by fear and concern, for before him on the edge of his bed, stood eighteen inches of morning wood poking out of the sleeve in his boxers.

“Holy Mother of Celestia!” Big Mac said dumbfoundedly. “What the hell happened?!”

His penis had apparently sprouted three inches overnight and was a lot wider than he remembered. The sunlight from the window cast a large shadow on his chest. Big Mac instead turned his eyes and felt as if he was looking up at a tall twenty story tower from a distant hill rather than staring at his own dick.

As his thoughts began to clear his head raced to figure out what could create such a dramatic change in his anatomy.

The potion! his mind concluded. The potion did this!

Anxiously, Mac quickly turned to his nightstand to look at the empty vial but stopped as his eyes fell upon his right arm. Before him rested an arm that looked like it was just a volumes short of surpassing Bulk Bicep’s biceps. Even odder, it looked as though it had grown longer along with his muscles. Every muscle on his arm from his hand to his elbow was larger, thicker and looked as if it was stuck in a permanent flex. Quickly turning to see the other showed it too had changed. Experimentally he flexed them up a bit and found his biceps and triceps bulge wider before his eyes, gasping as his sleeves fell completely apart.

Thankfully the rest of his pajama top was holding. He could definitely feel it standing against his torso. If he really focused, he figured he could probably tear the whole thing off just by flexing, considering it didn’t even cover his belly button anymore. This led him to believe that not only was his body packing more muscle, but his entire body had gotten taller too.

This is unreal! he thought as he felt his dick start to leak slightly. He quickly lifted himself off the bed only to hear the sound of ripping from both his boxers and his pajama top. Not wanting to waste anytime he walked as fast as he could to where his full body mirror stood causing the wood beneath him to crack. When reached the mirror panic overtook him.

This can’t be right. he thought to himself silently as he started to feel light headed. That mirror is supposed to be seven feet tall, only about a foot taller than me. Yet now my face is a least half a foot above it. That means I went from six feet two inches to about seven and half feet in the course of six or seven hours!

Upon realizing this, his eighteen-inch member started to drip like a faucet as drops of precum splashed against the wood of the floor. His mind panicked as he tried to stop the dripping with hands but cursed himself has his arm scraped against his flesh, stimulating him even more. Not wanting to make things worse, he withdrew his hand and turned away from the mirror.

This is bad! he nervously thought to himself. I can’t even look at myself in the mirror to see what else might have changed. I’m so fucking hard right now. I can’t even trust myself.

The floor creaked as he set his toned ass onto it, thinking about what to do. He closed his eyes, ashamed for indulging Zecora and himself. Deciding that dwelling on his mistakes wasn't going to solve his predicament he cleared his mind and imagined himself lying on a beach with nobody but the ocean and Celestia’s sun as company.

After his cock had finally settled down he meditated for another five or so minutes before reopening his eyes. He then stuffed his cock back into his straining boxers. As his hands grazed over his balls, he let go of his pouch and began to cup them. It seemed as though they too had gotten an upgrade and were competing with his enlarged sheath and dick. He swiftly drew back his hand as felt his dick twitch. Again, Big Mac had to force his mind on something else so as not to stir excitement down blew.

Not daring to check any other part of his body, he could only assume that the muscles under his shirt had also expanded which was a safe bet seeing as how tight pajama top had become. He tilted his head and let out a long sigh of frustration. Everything new about him was part of his innermost fantasies. Yet unlike in dreams this sort of changed had real world implications.

But maybe this isn’t so bad. He reassured himself. So long as I don’t get any bigger and I act like I’m not aroused life will still be the same. In the meantime, I need to find something to wear and get my ass over to Carousel Boutique. Or maybe I should sneak over to the hospital in case that potion has any more surprises for me. The only problem is getting passed the family.

Having plotted his next course of action, he tiptoed as gently as he could towards his dresser, taking into account his increase in both strength and size. Once there, he took out the bulkiest pair of cargo pants and put them over his boxers, not even daring to change into regular underwear. Miraculously the pants fit him like a glove, forcing a small grin on his face.

Well that's a relief. Too bad my arms would probably rip my shirts to shreds. This torn up pajama top will just have to do.

*Knock Knock*

The sounds of someone banging on his door made him jump, causing the room to shake and some of the objects on his shelves to topple over.

“Big Mac!” called the voice of his younger sister Apple Bloom. “I’m going to Scootaloo’s house with Sweetie today for some weekend crusading. I left Applejack and Granny a note, but I thought I should tell you.”

Buck No! He thought as he felt his heart beat quicken. If Applebloom sees’s me she’ll start asking questions. Worse, if my wardrobe malfunctions her innocence will be lost forever.

Putting his hand over his heart he let out a series of deep breaths.

“You girls be careful.” he said, trying desperately to sound like wasn’t having a nervous breakdown. “Are Granny and AJ up?”

“Granny’s still asleep and AJ just left with Rainbow and Pinkie Pie to do I don’t know what. Think I overheard Pinkie Pie say her ‘sense’ was tingling all over. I bet something really BIG is going to happen.”

The stallion let out nervous gulp. “I’m sure it’s nothing. You go have fun with your friends and stay safe. I think I’m going to have a late breakfast today.”

He listened to Applebloom’s footsteps as she headed for the staircase. Cautiously he made his way to the end of the room and looked out the window. When he saw Appelboom leave he knew it was safe.

As Mac made his way through town towards the hospital he couldn’t help but notice that every mare he passed was eyeing him. It wasn’t that they were gawking at him but he felt like every mare he passed couldn’t help but glance at him at least once, always with a smile. After he had traveled two blocks a part of him felt like forgetting the hospital entirely and just flex but he quickly reminded himself that he wasn’t in another dream.

Turning another corner he saw that he was passing the local Coltcuddler Bar that just opened up in town. As he passed the joint he noticed the stallions outside giving him the same admiring glances that the mares had been giving him. While the idea of guys checking him out wasn’t a comforting one it didn’t bother him as much as he would have thought. In his dreams stallions never admired him sexually but saw him as the perfect model of masculinity. While he could see a hint of envy in the eyes of the colt cuddlers he also noticed a sense of longing stirring within them.

“Hey handsome!” shouted an effeminate voice from the direction of the bar. Mac turn around and saw a skinny green unicorn wearing a black leather jacket and pants. The stranger ushered him to over with his index finger. Not wanting to be rude Macintosh walked over to him.

“Can I help you sir?” the farm pony politely inquired.

The stranger looked up into his eyes and smiled. “You certain can you gorgeous devil. The name’s Lime. I’m new in town and looking for a nice strong stud like yourself to have a drink with.”

A shiver ran down Mac’s spine as he realised this stallion was coming on to him. Taking a moment to catch his bearing he thought about the most appropriate way to handle the situation.

“I’m sorry.” he said a little bit flattered. “I’m not what you think I am.”

Lime gave him a coy grin. “Oh I think you are.” he teased. “You're the most gorgeous hunk of meat I’ve ever laid my eyes on. And I must say, you're one hell of a dresser. The whole ripped pajama top thing you got going really makes your muscles stand out.”

Big Mac took a step back and held up his hands. “Listen buddy. I don’t swing that way. I just had a little wardrobe emergency today.”

Lime face palmed himself and shook his head. “Oh Shit!” he said shamefully. He put his hand down and looked up apologetically at Mac. “I’m so sorry man. I’ve just moved her from Fillydelphia and was really eager to have a little fun. When I saw you pass the bar with that ruined shirt on I figured you were… Oh Celestia, I am so sorry!”

Big Mac chuckled. “Don’t worry about it. Ponyville is a very diverse town. I’m only a little flustered but not at all offended. A part of me is flattered but I’m afraid my barndoor is off limits.”

Lime sighed in relief. “Wow. I’m so glad you're not that upset. Believe me, I normally try to know for sure before I make a move. I just don’t know what came over me today.”

“Listen, I have a medical/ wardrobe emergency to get too. I really have to go but I hope you find what you looking for. Welcome to Ponyville.”

Lime’s cheeks started to brush up a bit. “Thanks. I’ll see you around. Oh! Before you go. If the two of us can’t be lovers could we at least be friends? Also could I possibly get your name?”

“Eeyup!” Big Mac said. “I have no problem with that. The name’s Big Macintosh.”

He could see Lime trying to suppress a dirty smirk upon telling him his name, struggling to keep his composure. While a bit unsettled Big Mac made sure not to show it. The last thing he wanted to do was hurt the poor stallion’s feelings. That’s not the type of pony Mama and Papa taught him to be. Instead, he waved goodbye to his new friend and continued towards the hospital.

Upon making one last turn he needed to make before reaching the hospital he once again caught wind of the small glances he got from the mares of Ponyville. It was as if every pony with an attraction to guys wanted him. A theory that triggered a small pinch of arousal in his groin. Luckily he made it to the doors of the hospital before could lose track of reality and break out into ecstasy.

Inside Big Mac walked to the front desk and looked down at the mare managing the desk who was busy filing her nails.

“I need to see a doctor or a nurse.” Big Mac said with distress. “Can you schedule a physical for me please?”

The receptionist looked up from her nails, staring silently as her eyes darted up and down examining his broad body.

“Ma’am!” Big Mac cried with the slightest hint of frustration.

“Oh!” she said shaking her head as if snapping out of a daze. “I’m so sorry. Just wait in one of the chairs. I’ll have somepony see you in a few moments.”

45 Boring Minutes Later

Eventually, Nurse Redheart came for Big Mac and ushered him to room 69. As he sat down on the chair in the room he took a good look at her. She was dressed in her traditional nurse outfit with her red-cross cutie mark embedded on her hat and the sides of her dress. The top of her outfit was partially unbuttoned giving Mac a good look at her C-cups.

With a clipboard and pen in hand Redheart began to quietly jot down some notes, taking quick occasional peaks in between.

“So.” she asked, her eyes still trained on the clipboard. “What seems to be the problem? You look as fit as a horse to me.”

“That’s the thing Doc.” Big Mac said. “I drank one of Zecora’s elixirs and I think it’s bring a personal fantasy of mine to life. I’d rather not tell you the details but it involves changes to my body. When I woke up this morning everything from my height to my private areas had increased in size.”

Redheart looked back up at Mac, making sure to really focus on him this time. Indeed, it did seem that he was a bit bigger than she remembered and the clothes he was wearing seemed awfully tight. Her eyes honed in on the different parts of his body as she started looking at him in an unprofessional way. The tight bulge in his pants looked so erotic and the bumps on his chest and stomach showed through his pajama shirt. The nurse began to sweat nervously.

“What’s the matter?” Mac asked has he saw that the nurse looked a little out of it. “Is something the matter?”

“It’s nothing.” she said sharply as she smiled nervously at him. “It’s just that I’m going to need to ask you to take off your clothes so I can properly assess these changes. I’m afraid that this sort of ailment needs a full body examination. Normally this wouldn’t be a problem. It’s just that…”

She looked up and began tapping her foot.

“It’s just what nurse?” Big Mac asked.

Drops of sweat began to fall down from Redheart’s face like drops of rain, her face blushing with embarrassment as she tried to cover her mouth.

“I’m sorry… but I think it would be better if you saw a male doc… doctor. Your current physique is having an adverse affect on me.”

Realising what exactly was “distracting” the nurse Big Mac’s thoughts began to race.

She’s afraid of acting out sexauly if I take off my clothes. he thought. I can see the lust in her eyes. Poor Redheart is trying everything she can to control herself. I’d hate to be the reason she lost her job, but this situation is just so…so….so…

A tingling sensation the likes of which he never felt before coursed across his whole body from the highest hair on his mane to the soles of his feet. Aroused, Big Mac let out and organismic moan, which only got louder as the feeling grew stronger. He could feel his body pushing outward in all direction as every part of him grew and swelled.

“What’s happening?!” Redheart yelled in concern.

“It’s… Oh… what I feared… But damn it feels so… oh Celestia I need more!”

With a final moan he lost grasp of reality and finally broke free of his self oppression.

He could feel his arms stretching, growing longer to accommodate his growing form, but also expanding in bulk. As new muscles grew under his biceps the the old ones continued swell. He could feel stacks upon stacks of muscles forming and growing on top of and below his biceps and triceps.

Meanwhile, what little remained of his pajama shirt was ripped apart as his pecs ballooned outward along with the rest of his torso. Mac looked down to finally get a look at his upper and lower body, an unge he had been previously avoiding so as not to simulate himself. Now that his shirt was gone he could finally see his growing six pack, and hollering as it slowly turned into an eight pack right before his eyes. Using his hands he felt along the spaces in between his abs, smiling gleefully the as they got deep as his abs put on more mass.

Big Mac’s legs lengthened as his calves spit the fabric of his jeans apart, revealing his ever thickening plot. Big Mac let out a whinny as he felt his widening ass crush and consume the chair he was sitting in.

What remained of his jeans was all but ripped apart by his expanding gradient cock that was widening and lengthening at an increasing pace. Soon nineteen inches became twenty-one inches before surging to a whopping twenty eight inches of erect stallion cock, it’s width now thicker than an average pony’s arm. Meanwhile his balls grew like balloons being filled with air. His cock shivered as his widening sack slid across the floor.

Redheart stared motionless, frightened and confused by what was happening. Yet as she watched the scene that fear was replaced with arousal. No longer able to restrain herself nurse Redheart violently tore the top of her uniform open and ran for Big Mac’s still growing dick. Like a feral beast she shoved the tip into her mouth, not caring that she could barely breath with it inside. As she pushed a few more inches into her mouth his shaft grew by two inches. Her throat began to tighten as the massive red monster started to clog her windpipe.

As his toes started to brush the bed in the corner aside Big Mac silently turned his larger head down to the struggling Redheart as he felt every part of his body surge at once.

One more spurt like that and I’ll rip her apart. he thought with concern.

As if abiding by his concern for Redheart the tingling subsided, but the pleasure it brought him was in full force. He had no idea how tall he was now, but all he knew was that he currently sitting on the floor with his head three inches from a ten foot ceiling. Every freaking part of his body was longer, thicker, and stronger, including his mane and tail.

All the while, a naughty nurse had his thirty inch tree branch of a dick lodged in her throat with no intention of pulling out. All ready he could see that her belly was starting to swell from the excessive amount of precum dripping into her stomach.

“You… have to pull out…” he said trying to sound concerned amidst his lustful moans. “You will drown if I go off. You gotta… You gotta… Dammmmittt!”

The massive stallion clenched his eyes shut as he felt his seed shoot out like a gizzer into the Redheart’s stomach. She rubbed the side of his dick as her belly burst the buttons of her uniform off while it expanded. It managed to grow four feet in height before she was knocked back across the room by the sheer force of Big Mac’s cum.

Her massive body broke straight through the door as her back slammed against the walls of the hallway. Surprisingly she felt no pain from this, which was odd considering the velocity and force at which her and her cummfiled belly had crashed. However, with Big Mac still in ejaclating like a fire hose, it coated her as she sat down with her enlarged belly. She really didn’t give a shit.

“Shower me!!” she screamed as stallion cum flew out of the room and onto her bloated body. “Cover me with your godly seed!!”

She frowned as big Mac fired his last load which just barely made it out of the room. Having relieved himself Big Mac opened his eyes and looked out at the drenched nurse just outside the door. As his mind came to back to reality he realised the seriousness of the situation.

“I’m so sorry nurse Redheart!” he shouted with an worried and apologetic tone. “This is what I was afraid was going to happen.”

The nurse simply giggled as she playfully rubbed the leftover cum over her bloated belly.

“Don’t worry.” she said. “The directors will understand when I tell her how unique your case is. For now I’m afraid I’m going to have to call your family and hand you over to a male doctor that can hopefully resist your alluring charms.”

Before he could protest, a wave of exhaustion swept over Big Mac. Too tired to complain, he closed his eyes and leaned his wide back against the wall.

I really hope this just another one of my dreams. he told himself. Cause if it is, this is definitely hotter than most nights.

Mind Into Matter

Big Macintosh’s shadow loomed over ponyville as he sat upon the throne his worshippers had made him. Hundreds of Pegasi clung to his erect shaft, with over his towed 30 feet past his 250 foot body. They licked, rubbed, groped, and smothered his meat, doing what ever they could to service this masculine god.

With magnified vision, Mac watched as all four Princesses of Equestria pressed their full tits against his metal ring. This image alone was enough to drive him to frenzy.

“Brace yourself, ladies,” he called out to the town, “It’s about to rain. I recommend all the straight stallions and foals get to your bunkers fast. While I’d prefer only the ladies stay, I know I can’t stop the rest of you.”

The majority of the males as well as every colt and filly ran to their the cum-proof bunkers. Everypony else simply prepared their body for the divine flood that was about to come. And cum it did.

Big Mac jerked back in his seat as his cock erupted like a volcano. Gallon after gallon of seed that his house-sized balls had stored was sent flying fourth. In less than 30 seconds, everything that wasn’t two stories was submerged.

Meanwhile Mac moaned blissfully as load after load sprayed forth from his godly meat, with no sign of letting up. A cum-soaked Twilight Sparkle flew up to him and shouted, but he could notice her not because of her size, but from the ecstasy of his never ending orgasm.

“Mac!” she screamed, “Mac, Mac!...”

“Mac! Wake up.” Twilight’s voice rang through what sounded like an intercom system.

Macintosh opened to his eyes, and let out groggy sigh. He found himself back in the hospital room, with a twenty-five foot blanket placed around his privates. Scanning the room, he noticed everything that had apparently changed while he was out. For one, all the fluids from his time with Nurse Redheart had been soaked clean. In front of him, he saw that a metal door had replaced the one his cum had hosed off.

Left of that, his eyes noticed that a new hallway window. Like the door, he figured it must have been place there with magic.

“Big Macintosh!” Twilight’s voice rang out again into the room again. “Can you please lower your head so you can see me? It is practically touching the ceiling. But try not to remove the blanket. The magic radiating from your groin is so strong, I could barely think straight before.”

I have magic radiating from my groin? Mac thought silently, feeling slightly aroused at how sexy that sounded. He leaned himself downward till his eyes were level with the window, where he saw the Princess of Friendship herself staring straight at his giant naked body.

“Twilight!” he shouted, moving back with fear.

“The doctors called me in after they ran a few tests on you and Nurse Redheart. I also had the luxury of interviewing Redheart herself, and I learned about every detail about your...” She paused for a moment as she struggled to find the right word. “Let’s just call it a physical. That’s what it was supposed to be, anyway.”

“So you know about Zecora?” Mac asked as his stomach began to churn. “You know about the potion she gave me.”

“The nurse did mention Zecora and something about a potion,” Twilight said. “But she was too intoxicated with some form of lust magic to speak to me. I’m worried the effects might be permanent, considering she swallowed enough of your seed to make her look eleven months pregnant with six or seven foals. And considering how powerful this magic is, she may very well be soon. Even with an oral intake, the cum-”

“Wait, how is that even possible!?” Macintosh interuppted.

“The magic you’re releasing is that powerful,” Twilight said nervously. “But I still don’t know what we are dealing with. You have to tell me the whole story, Mac. What was that potion supposed to do?”

Guess I don’t have much choice but to tell her the whole truth, Macintosh thought. He gulped. I just hope she doesn’t get too disgusted.

He took a moment to collect his thoughts before he opened his mouth to speak. “I’ll tell you everything,” he sighed. “But you probably won’t think mighty highly of me once I’m done. For a while now, I’ve had this little fantasy in my head.”

After hearing Mac out about his fetish, the dreams, his self-inflicted guilt, his meeting with Zecora, and the potion she gave him, he was surprised to see Twilight’s expression had not changed at all. In fact, she seemed very engrossed at what he had to tell her. Mac figured that if she was secretly repulsed, she was doing a damn good job of masking it.

“Thank you for being honest with me, Mac.” Twilight said. “This will certainly help identify what exactly is happening to your body and get it under control. With this new information, I can confirm that magic is warping reality in conjunction with your own sexual fantasies. How Zecora even got a hold on something so powerful scares me.”

Mac blinked. “You're not grossed out?”

Twilight giggled. “Believe me, I’ve read about a lot worse than macrophilia. After my brother and Cadence in a vigorous roleplay, i’m used to it.”

Big Macintosh gave Twilight a blank stare. “Macro-what? Also, what was that about your brother and Cadence? What do they like to do, exactly?”

Twilight giggled and blushed. “Macrophilia is what your fetish is called. There are a lot of variants of this one, but they all involve giants or giantesses. In this case, your variety of it seems to be a desire to become a giant, while others with the fetish would just like to see it happen.

“As for Shining Armor and Cadence’s fetish.”... Twilight drew a breath and made sure no doctors where listening. “They like to take turns eating or devouring each other,” she whispered. “They take turns either shrinking themselves or stretching their mouths so they end up swallowing the other pony. It grossed me out to see something like that, but they both explained it to me afterwards. Since then, I’ve been reading up on exotic paraphilia. It’s really interesting.”

Mac became lost in thought.

So I’m not the only one. Heck, there are even different kicks revolving around the same concept! A dirty smirk briefly formed on his face. Now that I think of it, I wouldn’t mind if a mare was the one towering over me. That would be pretty hot.

He thoughts came to a halt as he felt his shaft beginning to harden, causing a small lump to emerge from underneath the large blanket. At the same time, he saw Twilight’s clothes start to rip, as her body started expanding in all directions.

Frightened, she desperately tried to fix the buttons of her shirt, only to watch it get torn to shreds as her modest C cup breasts jumped four whole cup sizes. Her bra was destroyed instantly with in moments of the change. Meanwhile, her inflating ass poked out the back of her her skirt, just before her hips snapped them in two. All the while, her expanding wings remained in perpetual wingboner, the topmost feathers brushing against the ceiling as she continued to fill the hallway.

“Move to the wall, Mac!” she shouted, no longer needing the intercom to be heard. Big Mac stared in awe as Twilight snapped, “ Whatever you’re doing is sure as hell not helping!”

Mac galloped to the wall and watched as the Princess continued to expand. Her largened flower began pushing against the safety glass, causing small cracks to form.

“Mac!” She cried, as her growing jugs started coming dangerously close to his groin. “If you’re doing this, you need to this stop before I destroy the hospital! As sketchy as Zecora’s motives might be, I don’t think she’d give you a power this unstable unless you could control it. If my hypothesis is correct, all you need to do is concentrate and-”

Twilight stopped midsentence as the pressure from her plot shattered the glass, allowing her thick tail to fly out into the hallway.

Incredibly aroused, but more concerned about the ponies in the hospital, Mac closed his eyes and pictured Twilight at her normal size and fully clothed.

“Mac.” Twilight voice rang out loudly over the intercom.

He opened his eyes and blinked in disbelief. He lowered his head down and peeked through the mysteriously unbroken window. There he saw a completely dressed Twilight with a normal sized body and assets.

“Did that really happen?” Big Macintosh asked.

“Yes,” Twilight replied.“I’ve got to say, I think you might have given me a self macro fetish, Mac. As scary as it was, that felt really good. Almost sinfully so. Plus, this means that we can check you out of the hospital without destroying entire sections of the first floor.

“You… Really think I can control it?” he asked. “Just how powerful was that potion?”

Twilight sighed. “I’m almost afraid of the answer myself. Until I run more test before I know for sure, but from what I can tell it’s could very well be limitless. Worse, the way it’s warping reality kind of reminds me of a certain draconequus.

“Do you think he might somehow be involved in this?” inquired Mac.

The princess shook her head. “Zecora may be a tough book to read, but I doubt she knowingly borrowed magic from Discord. Besides, I already tested for that. Discord’s chaos magic is sporadic and unpredictable, whereas yours seems to be powered by your own lustful imagination and desires. Luckily it seems you are capable of controlling it.”

“Ain't that a relief,” Mac said sarcastically. “What, I’’ll just imagine myself at my normal size in my work clothes and suddenly....”

Before he could finish his sentence, he found his vision had suddenly changed. Where before he had to couch to see Twilight, he was now standing straight up with only a foot higher than the Alicorn.

“Sweet mother of Celestia!” he shouted, as he looked dumbfounded as he gazed down at his fully clothed body. “Twilight, you need to help me get control of this!”

The red stallion jumped a few inches back as Twilight teleported back into the room, forcing a yelp out of the shy apple farmer.

“Please warn me next time you’re going to do that,” Mac said as he tried to catch his bearings.

“Sorry,” she said sheepishly. “Anyway, let’s get you checked out and I’ll walk with you home. I already have a plan.”

Once Big Mac was checked out, he and Twilight left the hospital and walked together in the direction of the Apple Family farm. The sun was just about to set as the they approached the dirt road that lead up to Sweet Apple Acres. The whole time the two causally conversed with each other about the situation.

“You still look a little worn out from your check up with the nurse,” Twilight Sparkle joked.

“That reminds me,” Mac replied, “Is she gonna be alright?”

Twilight blushed. “She may have a bloated belly for a while, but like I said earlier she may get abnormally pregnant with all that magic spunk inside her. If you have a hyper breeding fetish as well, than the chances are almost certain.”

Mac thought about it for a moment and slapped himself on the head.

“Shit, Twilight!” he said, as he was overcome with hysteria. “What do I do? What if she does become pregnant? What if she doesn’t want to go through with the pregnancy? Who will take care of the kids if she does? How many kids will she have? What about her health?”

Twilight patted Big Macintosh on the back. “Luckily, the only thing you and the nurse have to worry about is what you want to do with the foals. I told Nurse Redheart about the possibly of a magic induced pregnancy, and she actually seemed thrilled. Her exact words were ‘I can’t wait to have twenty or thirty foals squirming in my stomach! Maybe even forty!’ It’s possible the magic could be affecting her mind, but either way she seems set on going along with the pregnancy. Plus, the fact that your magic protected her earlier should ensure that she and the foals would remain healthy.

Mac let out a huge sigh of relief. “I feel like I just dodged a bullet there. I’ll be sure to talk to her about child support, adoption, or even take some of them myself. Us Apples are used to raising big families, and I wouldn't want a single lady to bear the burden of that many foals. I also wouldn't be comfortable with the other option, but that’s a personal thing. Even though this is a relevant topic given the circumstances, I don't want to stir any controversy between us.”

Twilight nodded. “I agree. I hate discussing politics with friends, especially on those really sensitive topics.”

Mac nodded. “I’m exactly the same. Anyways, while we are on the topic of politics,” a devious smirk slowly formed on his face. “I’ve heard a few rumors about you, Twilight. Is it true you're secretly plotting to pass any government-run health care?”

“What!?” Twilight stopped. “Who in the flying hoof told you that!?”

Mac chuckled as his grin grew wider. “Relax. It was a joke. I honestly couldn’t give a crap about politics so long as it doesn’t affect the family business.”

“That’s good.” Twilight said cheerfully. “Because business taxes are going up next week. Health care doesn’t pay itself, you know.”

“Wait, wha-” Mac’s eyes widened as he came to a brute stop. Twilight trotted up next to him.

She covered her mouth with a hoof and snickered. “Gotcha!”

The two burst into a fit of laughter until both their sides were sore. When they calmed down, they continued to up the dirt road. As the roof of the farm came into view, the two of them stopped and looked at each other.

“I’m really worried about losing control, Twilight,” Macintosh said softly, “I’d rather my family not know about Zecora and the potion, let alone my deviant fetish. Are you sure I’ll be alright at home for tonight?”

Twilight nodded. “My best advice would be to avoid materbating.” She smiled awkwardly. “It’s the fastest way for you to lose control of your imagination. If you do find yourself growing, you'll need to exert your will like you did the other day. Lastly, if by any chance you do get caught, with a little bit of practice, you might be able to cause other ponies to lose those memories.”

Mac stopped himself. “No way! You're messing with me again aren't you?”

Twilight shook her head. “It’s only a theory right now, so don’t try it until we know for sure. That can be one of things we could test in private. Which reminds me,” Twilight paused for a moment and place a hand on the stallions pecks. “Can you meet me at the The Castle of the Two Sisters tomorrow? I want to help you get a handle on this. Additionally, it’s my duty as a Princess to notify Celestia about your condition, and I’m afraid that includes all the details.”

Mac gulped. “I can set a time tomorrow around noon if I get up early, but do you really to tell the Princess everything?”

Twilight nodded her head. “I’ll fly to Canterlot personally to tell her, so Spike wouldn't have to know. Don't worry, I’ll try and leave out some of the cruder details, though I will need to mention Nurse Redheart.”

Macintosh lowered his head and stared down at the ground.

“Chin up, big guy,” Twilight said, as she moved her free hoof to rub Big Mac’s chin. “I happen to know Celestia has a few peculiar fetishes of her own. One involving her own guards, an appetite enchantment spell, and 64 tables of baked goods and ice cream.”

Twilight’s odd tidbit about the sun Princess caused Big Mac to perk up and smile. That, and the fact that both her hooves were touching him. However, he made sure his thoughts remained clean, not wanting any repeats from the hospital - at least for today.

“You know what’s really funny?” he asked cheerfully. “For some reason I could totally see Princess Celestia doing that. I bet those guards get monstrously obese.”

“Not all the time?” Twilight said as she licked her lips. “Sometimes she casts a spell to make sure their upper bodies gain muscle as opposed to flab. My books call it a sumo fetish.”

“You know, that now that you mentioned it Twilight, that actually sounds-”

Before Mac could imagine what he’d be like as a sumo, Twilight got onto her tip toes and locked lips with Mac. This caused Mac’s eyes to widen as Twilight pushed her chest up against his, and caressed the sides of his back with her wings.

Stunned and speechless, Mac watched as Twilight broke away and shook her head.

“Forgive me,” she said, shocked by her own actions. “That was so unlike me. Mac, you have to realize i’m not the kind of pony who fools around. I’m a Princess and I should have-”

This time, it was Mac’s turn to shush Twilight. “It was probably that lustful aroma you mentioned earlier. Every mare in town and at least one stallion that i know of been eyeing me since I woke up. Besides, that kiss of yours just saved me from growing again.”

Twilight shook her head. “But I already examined you after you shrunk. The magic that was affecting my mind early on wasn’t-”

Macintosh interrupted her with a quick peck on the cheek, causing them to turn rosey red.

“I should head to Canterlot,” Twilight said nervously as she leapt into the air and flapped her wings. “Please be careful Mac.”

Mac watched as Twilight took off into the sky towards Canterlot. The sun long since set, Big Macintosh walked calmly to his house, as he thought about his time with Nurse Redheart, and his surprisingly enjoyable walk with Twilight Sparkle.

Perhaps this potion isn’t so bad after all, he thought as he went inside. However, as soon as he walked into the door, he immediately retracted his statement.

“What in tarnation is this I hear about you going to the hospital today, brother!?”

Let's do the time warp again!

That night in his room, Big Mac could hardly sleep. His mind still thinking about the moment AJ had cornered him about his trip to the emergency room. “I can’t believe how many lies I had to tell her.” Big Mac thought to himself, “And how things could get so hostile between us.”

The truth was he had been caught in a situation where lying to AJ was actually the safest course of action. “I just felt ill today AJ” he had said, and after that it was like a chain reaction. She then followed up by asking what was hurting him, to which he said. “My stomach felt sore today.” After that, the questions kept rolling and lies just kept on coming, one lie leading to another and then another. All the while, AJ eyes through him, as if they could peer into his very soul.

“But what choice did I have?” he whispered to himself, shifting his body as he did so. “Tell her I have reality warping powers that are fuelled by my sexual fantasies? That I not only filled Nurse Redheart with enough cum to inflate her to an insane degree, but somehow got her hyper pregnant from oral sex? That every mare including Twilight had fallen under the sway of his newly discovered powers?” Of course, the idea of using his new powers to alter AJ’s mind did cross his mind, but he quickly discarded them. Until he and Twilight tested the risks, it was too dangerous; and even then, the idea of messing with his sister's thoughts - or anypony for that matter - didn’t seem right to him.

“How did you even hear about this?!” He had said, more irritably then he would have liked.

“I saw you go by there today while I was helping Pinkie Pie.” AJ had replied with a frown. “I was worried that you might have gotten infected or injured during you trip to the forest and that you were trying to cover it up without me knowing about it.”

“AJ!” He had protested! “You know if there was anything I thought I couldn’t handle on my own I’d let you know.”

Mac her heard her huff as she as she'd crossed her arms and peered up into his eyes. “Then why do I get the impression that you haven’t been completely honest with me!?”

It was then he realised that he was only making things worse for himself. With a soft sigh, he walked past and made his way towards the staircase.

“There are some thing you not ready to know yet AJ.” he had told her. “Not until I figure them out myself.”

“What the flying buck does that even mean!” she screamed. “And did you just admit you were bullshiting me this entire time? What has gotten into you Mac?”

So now here he was, lying in bed, hungry and guilt ridden at the fight he and his sister had. Damn her sharp instincts. It would only be a matter of time before she learned the truth the hard way, and if that happened, she would never accept him. He had to tell her on his own terms, but only when these new powers were under control.

Mac’s line of thought was then broken by the painful rumbling of his stomach; he slammed his fist against the bed and grunted, regretting his decision to skip dinner. “Sweet Celestia what I wouldn't give to have a full meal in my stomach right now.” he whispered to himself.

Then, like magic - or perhaps by magic - his hunger vanished, and he instead felt as full as having eaten a complete Gratefulsharing dinner. Confused, he lifted his pyjama shirt and placed a hand on his stomach, and felt resistance. Where once there had been nothing, there was now something. Even without his hands, inside he could feel his intestines slowly digesting a meal he could have sworn he never ate.

“Just what the hell have I become!?”

After finally getting a few decent hours of sleep without any of those pesky fetish fuelled dreams, Mac got out of bed and looked himself over.

“Thank Faust!” he said with a loud sigh of relief. “I’m still normal… physically at least. Unless…” He quickly pulled down his pants and underwear and gave his drunk a quick once over. “Eeeyup! Still above average as far as dicks go, but no ways bigger than what I’m used to having between my legs.”

“But why?” he wondered. After everything that happened yesterday, there was no way his psyche wouldn’t have gone hog wild with lewd growth fantasies that would no doubt trigger his power. Then he remembered his fight with Applejack and how upset it had made him feel. “Perhaps all that guilt kept me from being in the mood. That won’t work forever though. I’m going to need to get control of these powers so I don’t have to worry about my cock bursting out of my house.”

As soon as his mind formed that sentence, Mac felt a powerful stir in his loins. The moment he felt it, his he began to panic.

“Apples!” he said out loud. “Think nothing but apples!”

Ignoring the arousal, he began to repeat the word ‘apple’ over and over again so as not to turn his extremely hot notion into a reality. He knew he was a time bomb just waiting to go off. His only hope of maintaining to his cover would be to leave immediately and find Twilight. He got dressed, brushed his teeth, and walked straight out the door without all while mutter that one word that would save his siblings and granny from indecency.

“Apple, apple, apple, apple…”

This continued all throughout his walk to the Castle of The Two Sisters where Twilight would be waiting. The journey through the forest was beyond nerve racking for the farm pony, not because of the deadly creatures that lurked there, but because any minute he might sprout a ten foot erection right in the middle of the road. Thankfully, he managed to make his way to the castle and over the wooden bridge without incident. Having reached the front gate, the earth pony stopped his chanting and struggled to catch his breath.

“I…. huhh… think I’m… safe.” he huffed as he took a moment to catch his bearings. “But I’m probably early. I told Twilight I’d be here at noon, but who knows how long I actually…”

“Mac!” Twilight voice rang out in his ears. “I wasn’t expecting to see you till later.”

He turned around and smiled with relief as he saw Twilight walking casually across the wooden bridge.

“I was kind of in a hurry Twilight.” Mac chuckled. “A naughty idea popped into my head and I was afraid my privates were going to start growing.”

Twilight chuckled. “Well, then it’s a good thing you got out of there quickly.”

Mac tried to force a smile but to no avail. He slouched his shoulders and sighed “In the end I guess it doesn’t really matter. Applejack found out that I went to the hospital yesterday and the two of us had an argument.”

Twilight listened intently as Mac recalled the harsh exchange he and his sister had, and how he lost sleep and how he had used his power to sate his hunger.

“I think the only reason I didn’t have any dreams was because of how worked up I was. I’m afraid if I don’t get control soon, Twilight, Applejack going to find out about my powers the wrong way.”

Twilight gave him a comprehending nod. “Don’t worry Mac. With my help, you will be able to control this without drawing unwanted attention. I wrote to Princess Celestia and explained the situation. She said she is confident that I’ll be able to help teach you how to properly handle your powers.”

“Hold on,” Mac said pushing his hands out in a halting gesture, “You saying she’s not worried about this at all. I’m one boner away from destroy all of Ponyville and she’s leaving this all on you.”

Twilight giggled. “This just how the princess normally does things, if Ponyville ever came into any real danger, she’d be here in a heartbeat.”

“But Ponyville could very well be in danger!” Mac protested.

“Which is why I shall intervene if things do get out of hand!” A voice from above cried out.

The two of them looked up to see Princess Luna descending down towards them, landing right between them.

“Princess Luna!” Mac said with surprise as his eyes were drawn to Luna’s gorgeous body, her outfit leaving little to the imagination and much of her cleavage exposed. Gold Trimming adorned every edge and exaggerating her curvy figure and highlighting the dark fur of her exposed abdomen.

“Greeting ye peon of large muscle.” She said experimentally, a wide smile adorning her face. “My Sister has asked me to give Twilight any assistance should she require it.” Mac flushed as her expression shifted from excited to starry eyed, as she lunged forward and began to massage his pectorals from beneath his undershirt. “She also said I may join Princess Twilight should things get… interesting.”

Mac gently brushed her aside and took a setback “Ah Princess Luna…” Mac said, “I’m very honoured that you’ve come all this way, but I’d rather make sure I’m in control before you go planting any suggestive ideas in my head.”

Luna nodded her head. “Forgive me Big Macintosh. That was very informal of me and highly inappropriate. I’m still getting used to, ‘flirting’ as ponies today call it. I remember you well from the carnival a few years back, and hearing about your power simply made my nethers tingle like that of a star being born. Wile, after Tia told me, my nethers were so wet that…”

“Ok…” Twilight said as he covered Luna’s mouth. “TMI, Princess.” she let go of Luna’s mouth and walked up to Big Mac. “Please forgive Luna. She hasn’t been with another stallion since her return from the moon, and she says she been saving herself for a true man. Let’s just go inside and begin, shall we.”

Mac was about to open his mouth when Twilight horn lit up and teleported them, leaving Luna all by herself.

“Damnit.” she thought. “I knew I should have worn a more revealing outfit.”

“Alright.” Twilight said as she walked towards Mac who was sitting down quietly by one of the library tables. As she approached, she drew a deck of cards from her bag and shuffled them with her magic as she took a seat on the other end of the table. When she was done shuffling she set the deck down on the table and drew three cards. Mac watched as she examined she underside of each card carefully before placing them down.

“What cards did I draw?” she asked.

The stallion shrugged and scratched his head. “How should I know?”

Twilight blinked. “Ok, so this is the first time we’ve had this conversation.”

“Huh?”

“It will all make sense in a minute.” Twilight said as she presented the three cards to Mac. Mac flipped them over and looked at their pictures. The three cards were a Griffon, a Dragon, and a Pegasus respectively.

“I need you to memorise those cards Mac.” Twilight said. “Then, using your mind, I want you to reset time to before I drew these cards, just like you did in the hospital yesterday. However, this time you have to reset my memory as well.”

“Do you really think I can do that?” Mac asked, somewhat incredulously.

“Positive!” Twilight assured him with a confidence. “After doing some research, I found a book which talks about similar potions, like the one Zecora might have given you. However the book only regarded it as legend or myth, but I think it’s safe to assume that it’s the same potion.”

“Did you bring the book with you?” he asked.

Twilight shook her head. “I did, but that can wait Mac. Just please, give what I said a try, and then maybe we can move on to something more… recreational.”

“Twilight!” Mac sighed. “I really do like you as a friend, and Princess Luna too, but that doesn’t mean I want to go around having sex with all of you, especially after the whole Nurse Redheart thing.”

Twilight blushed. “I don’t know what’s gotten into me. The lust magic only activates when you grow, so I’m not under any spell. But…”

Mac blocked as the alicorn start to trail off. “But what Twilight?”

She turned her head nervous as she tried to find the right words to describe her feelings “Yesterday, when we were walking, I really felt good next to you. We joked together, we laughed together and… well, it was just nice finally hearing you speak for once. Till yesterday I never realised…” she paused. “Just how charming you could be.”

Twilight sighed. “You never really needed any magic to make yourself look more attractive. You’ve always such an eye catcher amongst the girls, though we’ve all made sure not to say this to Applejack.”

Twilight reached out a hand. “I’d like to help you unwind Mac. There’s nothing wrong with having a little fun once in a while so long as you're responsible about it. And with my help, you should be able to get control of these powers and live out your dreams without any worries whatsoever.”

Mac gave Twilight a wide smile. “That does sound really fantastic when you put it all like that. However, I don’t think I can give you the time you want Twilight. I only ever imagined falling in love with one mare, and now I have an entire town that all wants me because of some stupid spell.”

Twilight smiled as her horn lit up. “We don’t have sex to have a good time.” she said as she slowly unbuttoned her shirt like a naughty secretary. “You just need to grow for me big guy.”

“Twilight!” Mac cried out as he himself start to puff out ward with bulk, size, and girth. With every article of clothing Twilight took off, Mac spouted six extra inches and at least two pounds worth of extra muscle. His clothes were already ripping at the seams as his package pressed against his jeans, becoming tighter and more pronounced by the moment. “Please stop! I can’t control this!”

Twilight giggled once she had stripped down to nothing but her dark purple underwear and stockings. “Don’t fight it Mac.” She said as she bent down and sat on the floor, her tail wagging as her wings became fully erect. She began remove her stockings with her magic, deliberately taking her time, as her hands reach back to the strap of her bra.. “Embrace and enjoy this wonderful gift of yours. I promise me and Luna will stop you if it gets too much. Just relax and focus on growing until your balls encompass the throne room and your shaft topples the east tower.”

With that, Mac’s mental restraints broke, all with a score of other things. The first casualty was the chair, shattering under the bulk of his expanding toned red ass. Next his jeans and underwear were torn apart at the seams as his expanding dong tore past the fabric and onto the wooden table. Hearing the table creek, Twilight scurried back a bit as Macs hard on grew bigger and wider, causing the small reganuare table to split under its weight.

Had his mind not been clouded with lust and pleasure, Mac probably would have been worried about splitters, but that was the last thing on his slowly eroding mind. All he could think about was the joy as his last article of clothing - the legs of his pants - were pushed aside to make room for the ever growing titan among ponies.

“Great Mac!” Twilight called cheered in excitement. “Now focus on making it stop!”

This caused the rational part of Macs mind to speak to cry out, forcing him to halt. His eyes opened as he shook head a bit to help him regain his senses. Once he had purged himself of lustful thoughts, he peered down and Twilight and glared at her. “What the hell were you thinking teasing me like that!” he shouted. “Just what were you trying to do Twilight?”

Twilight got back onto her feet and flew towards the now behemoth sitting butt naked on the cold stone floor. “I wanted to see if you could stop yourself under pressure, which you have.”

Mac grunted. “So, all that stuff you said back there was just to put my mind in the gutter. That’s cold Twilight.”

Twilight flew closer to Mac, her entire body just barely taller than his head alone. “You're wrong! I won’t deny I might have taken the foreplay a bit too strong, but it was only to get you excited enough to grow. I really do like you Mac, even if the feeling isn’t mutual.”

“Now I wouldn’t say that.” Mac said as his frown shifted to a warm gentle smile. “I can tell you right now there definitely a lot about you that really like. You’re smart, resourceful, a great conversationalist, and one of the most caring ponies I know. You’re also very good looking if you don’t mind me saying. You have a lot going for you Twilight. He lowered his head and closed his eyes, as his mind thought back to a certain Zebra. “However, there's also this other mare I think I might like. She’s kinds of a mystery, but in an enchanting kind of way. It could be she's just a lustful, obsessed, hermit, but what if she's not? What if she feels the same way I do about her after I saved her life? Last thing I want is to do is hurt somepony or break another ponies heart.”

The Princess of Friendship nodded. “I completely understand Mac. Again, your concern for the well-being of others only makes me more certain that you are the stallion for me. Luckily for us, I happen to know a solution to this little dilemma, one that I'm sure will make us all happy. Let’s not worry about that now though. I would much rather we get started." she made small gesture with her right hand. "Please stand up and look at yourself.”

The stallion looked down at himself and was immediately stunned. Stricken with awe, he proceeded to get back on his feet so he could truly get a grasp on what he had become. He made sure to tread gingerly, struggling a bit as he lifted himself up, getting used to his new center of gravity. After some trial and error, the stallion found his balance and proceeded to evaluate himself.

“Faust, Luna, and Celestia!” he muttered softly to himself but not enough to prevent a few books from vibrating. “I really am a god Twilight!”

“Or at the least the body of one.” he thought. Standing sixteen and half feet tall and five feet wide, his arms bulged with muscle and a chest that ballooned with meaty pecs. The cool feeling of not six, but eight bulgy abs each one as hard as stone. Reaching back, he could feel that his mane and tail had also grown longer and thicker to match his current size.

Even lower, he could feel his ass cheeks had toned up nicely as well, yet they were just toned enough not to be considered fat, but in no ways skinny. He gently lifted his legs up and felt no added resistance in movement despite the added bulk and weight. If anything he felt swifter, which seemed all but impossible consider how much mass his body was now backing.

And last but not least, his attention came to his most sacred of body parts. They were the pièce de résistance of masculine power and pride, one that put all others that came before it to complete and utter shame. These vast and pillaring objects were none other than his genitals.

His mighty balls alone were four feet in diameter and about eight feet around, practically pushing against his bulking legs from space. If he wanted to, he could probably use them as a makeshift bean bag chair. Even more astounding, he again felt that this extra increase in mass would not hinder his movement, despite the laws of natural physics. Were he at his normal height, he could probably do the running of the leaves and still be just as agile, perhaps even more so.

Then there was his cock which, despite having softened a bit after his initial burst of ecstasy, was completely level with his head. This meant that his full length stretched well beyond his current height. Were it not for his own squeamishness of performing oral sex, he could easily blow himself off right then and there if he was so inclined - which of course he wouldn't but the fact that he was capable of doing so filled him with a strange sense of accomplishment, even if it wasn’t his thing.

“Incredible he thought.” As he reached out with his massive arm to stroke the tip, causing it to rise to full length and gently poke the eight foot ceiling. “Faust, it's more intoxicating than what I felt in my dreams, such power, such strength, such pure masculine beauty.”

“Alright” Twilight cheered from below, “Way to go Big Mac! I’m surprised the floor hasn’t caved in yet considering we’re on the top floor but I’m not going to complain about that either. Please take your time to enjoy yourself, or trying growing more if you want. After that, you can reset things back to when I drew those cards.”

Twilight was about to fly down before something remembered something important. “Wait! don’t try to undo this yet.” She raced towards Big Macs head, nearly colliding with his meaty red pole, which really wouldn’t have been all that bad.

“Something the matter Twilight?” Mac whispered as quietly as he could, which to Twilight sounded like a his normal speaking voice.

Twilight sighed. “I wanted to tell you the idea I had, about regarding how you choose your partner. Equestria laws states that it’s not illegal to have a harem so long as you don’t display favouritism or mistreat any of your spouses.”

“Really?” Mac said with genuine look of surprise. “How long has that been a thing?”

“I think it was enacted sometime during the Renaissance, but it's become kind of obscure in the modern era. My research tells me even when it was common practice, the harems were either disbanded when the head mare or stallion of the harem didn’t keep their vows regarding favourite. Other times, there were cases of both male and female sexism and mistreatment towards spouses from monarchs and particulars alike.”

“The why didn’t they just make it illegal?” asked Mac.

“Because some of the harems were happy” she stated. “Even when parliament tried to step in, splitting these happy couples up became a huge issue, plus most ponies figured one special somepony was enough.”

“Well in my opinion, there’s nothing wrong with two much love, especially if it’s genuine and true. But I guess not everypony is capable of loving equally.”

“Well what do you think Mac, do you think you're capable of loving equally?”

Mac thought long and hard about Twilight's questions. Could he do it? He certainly thought he could. He was a simple, hardworking pony who just wanted to do his best for his family. Perhaps he could do the same with mares he chose to wed. He certainly didn't favourite little Apple Bloom over Sweet old Apple Jack. And if the mares he wed loved him back, and he injured loved them, why could he share it. After all, there was more than enough of him to go around now!”

Mac gave Twilight a warm smile. “I think I can, starting with you Twilight.”

“Wait, really?” Twilight said in disbelief as she felt her heart suddenly race. “Mac I, this..”

“But let’s not think too far ahead just yet.” Mac said with a smirk. “Instead, let me show you just how much control I think I have over these strange powers. Grab onto my cock. It’s time I stopped worrying and just live the dream.” He exclaimed, before he started to grow again.

As his shoulder brushed against the end two opposite end of the room, and floors below finally started to cracks, Macs expanding dick burst forth from the castle and into the cool the open, the cold air immediately stimulating him further. Yet just before Twilight could was about to reach the outside, the floor below caved she and the glowing red shaft dropped.

Luckily the fall wasn’t great. Macs feet nearly sank through the floor; while the boulders between his legs crashed right through all four floors of the castle, demolishing them. It barely felt like a fall at all to him, and only gave him more room to fill, as his bulk expanded and collided with the remaining rooms.

Meanwhile, Luna watched from afar as the castle was destroyed, every wall starting to crumble from within, Mac’s red pillar rearing from the hole in the ceiling, pushing masonry and slate aside to create an even wider hole. This was followed with the emergence of one expanding red arm from one side, then another arm, then a head, the two bulky legs, until finally, Mac’s ballooning red testicles that burst forth instantly demolishing the entire front wall of the castle, sending bricks soaring past the gorge and into the Everfree forest.

“Under normal circumstances I figure I be more upset.” she told herself, as she slid a hand down her pants. “Though I know it will be fixed soon, so might as well enjoy this for now.”

As Luna prepared to furiously finger herself. Macs had all but broken free of the castle like a dragon from its egg. Consciously, he halted his expansion and looked up at Twilight, who was clutching his fifty foot shaft for dear life.

“You do have wings you know, just in case you forgot” Mac teased. “If Little Mac is getting too hard to hold onto, you could try gaining purchase on another part of me.

With super pony hearing, Mac could hear Twilight call down to him. “This is most dick I’ve gotten in my entire virgin life.” she protested. “Even if it kills me I’m not letting go.”

“Well then, at least let me give you a nice place to sit.” Snicked the giant.

Twilight felt her leg tingle a bit as her body started growing alongside Mac, any clothing that she had forgotten to remove was shredded. Realising what Mac was doing, she let herself slide down the massive mountain of meat like a fire pole, even as her boobs started to brush against it. She stopped for a moment when she collided with his equine ring, but quickly readjusted her course. Eventually, Twilight's felt the base of macs arch dip between her fattening ass cheeks, which he made sure were extra plump not only for Twi's comfort, but so he can give his "Little Mac" a good workout.

“Hope you don’t mind the extra padding to your flank Princess.” Mac smirked as Twilight's slowed down a bit; she had become half of his height. “It’s all for your comfort.”

Twilight responded by grinding her fattened ass against the base of his shaft. “You’re lucky I’m not Rarity. She would have had a fit if you screwed her figure over like that.”

“I’ll keep that in mind in case I ever try something like this with her.” he said as took a nice casual seat on his balls and put his hand behind his head. He took in a nice deep breath. he was approaching four-hundred feet tall, with dick being about a hundred feet taller than him. His fingers alone were about the size of the trees below him, only to surpass them mere seconds later.

By now, all of Ponyville could probably see him, his sister probably throwing a fit, and that Lime fellow probably jerking off from his widow. But honestly, he didn't care. He was with a mare that not only expected his kink and appreciated his body, but admired him as a person. Plus, he was finally living his dream as everything about his body expanded.

Mac felt the a chill across his tip and shutterd. “Twilight, I think my dick just touched a cloud!” Mac roared as he to look upward only to confirm his suspicions. “Eeyup, that’s a cloud alright.”

“Sound just about finished.” Twilight teased as she tried to cup her thirty-foot breast into her silently chubbed hands. “No way am I letting a cloud beat me.”

She lunged forward and pressed struggled get as much of Mac’s shaft in between her cleavage. With each squirm she made send even more shivers up Mac’s shaft, filling his body with pleasure. The giant groaned as pleasure he never even dreamed possible, as Twilight continued to squirm her tits forward until at last until at last Twilight had half of it fully between her jugs.

“Oh Celestia Twilight.” Mac moaned as Twilight began to shake her tits up and down as they bobbed against the sides of his dick, but not even encompassing his full with. “Let me give you a help with that.”

Now it was Twilight's turn to moan as the growth of her tits exaggerated to the point where they were as long as Macs shaft was wide. His pole now fully captured by his lovers embrace. When that happened, Mac felt his organism about to rocket, but he thought it off.

“Had enough yet big boy?” Twilight shouted as his body approached four-hundred feet.

Mac clenched his teeth, trying to desperately to make the moment last longer, but he had reached his peak. He clenched his sides and clutched his eight-hundred foot dick with all his might.

“EEEEyyyuuuuupppeeeee!”

Then like a volcano he came! And by holy hell did he cum hard! He came so fucking hard, that the sheer volume of his first squirt could have filled an entire like. Even though the only areas that could see him were Ponyville, Canterlot and Cloudsdale, everypony in from Appaloosa to the Crystal Empire could at least see a glimpse of his cum shuttling skyward.

Mac could feel the feel cum rain down on him just as his first shot subsided to make way for his second. It rained onto them and all across the forest, causing floods and tidal waves.

The gorge surrounding the start to fill up with cum, before it spilled over and started to flow into the cave containing the tree of harmony. However using the power of the elements, the tree was able to create a barrier around the cave which prevented the cum from reaching even a single one of its roots. Even as the outside of the cave became completely submerged, the inside remained undefiled.

The same could not be said for the goddess of night, who had been too busy massaging herself to prevent herself from being carried away by a river of cum. She was frightened at first, but Macs power kept her and every living thing engulfed by his flailing floods safe from harm.

Miraculously, none of the falling spunk was landing in Ponyville, thought they could all see the white storm raining down upon the forest, and the red giant that was spraying it. They all stared in confusion, awe, terror, and in some odd cases… admiration, and even desire. However, pony stood with nearly enough attention and shock then Applejack, who just remained motionless at the horny red titan that was her older brother.

And through it all, Mac’s rate of growth all but doubled as his legs and his balls passed over the gorge and toppled over entire swathes of forests. All the while, Twilight continued to press her fattening ass down on Mac, while her tits caressed his shaft as milk poured out from her tits and down into the cum filled gorge below.

After ten whole minutes of cumming and growing, macs orgasm died to the point of that of light trickling waterfall. Lifting himself back to his feet, he examined his final height At nine hundred feet, he could see well beyond the Everfree forest and past Canterlot. His 1300ft boner hung high above his head, leaking a steady stream from his still cumming canal. His dangling red apples were as wide as Canterlot Castle, each, hanging almost 50 feet off the ground. His legs and arm muscle were also bulkier and more pronounced, yet still had also grown in a way that allowed him to carry the extra increase in mass without looking as ridiculous as disproportionate body builders. To confirm this he rubbed his abdomen and felt not eight but now twelve sets of abs, proving that his overall shape was growing to support all the extra mass.

“That was fantastic Mac.” Twilight said shouted from the bottom of his still erect shaft. Her smile faded however as she looked upon the many devastated acres of the Everfree forest, with toppled trees and entire bodies of cum flowing everywhere. “But I think we might have over done it.”

Mac shook his head. “No living creatures pony or otherwise were hurt! I feel really in tune with this power now Twilight, I can feel the presence of every soul for miles.” And it was true. Even now, he could the presence of the Everfree monsters, who were all cowering in fear of his dominance. He could even sense the birds, the squirrels, and even the bugs, scurry for amidst the destruction the ruins of the forest. He could feel Princess Luna about two miles away submerging herself in a pool of his own seed.

“It feels so divine Twilight.” He said. “I can even feel Fluttershy hiding in her cottage and….” he paused, as his giant eyes broke into panic. “Oh no… AJ’s watching me. I can feel her watching me from the farm.”

Not wanting to let the guilt ruin what had probably been one of the greatest moment in his entire life he closed his eyes and tried to call upon his power.

“Gotta reset time.” Mac thought desperately as he shut his eyes and focused. “Gotta go back and undo everything. Make sure nobody remembers any…”

“What cards did I draw?” Twilight's voice rang out.

The stallion opened his eyes in bewilderment. He was back in the Library of The Two Sisters, completely intact. He was sitting by the table he destroyed with his cock, with Twilight sitting at the other end, holding three cards.

Mac rubbed his neck, as his mind wrestled to comprehend that he had somehow jumped backward in time. After a moment or so to catch his bearing, he eventually he looked up at Twilight and gave her confident grin. "A Dragon, a Griffon, and a Pegasus. Those are the three cards in your hand right now."

Twilight gasped. “How did you know that Mac? Did I show you them by accident, or was that a lucky guess?”

Mac chuckled then jumped out of his chair. “Twilight it worked.” he screamed as he made his way around the table towards Twilight. He lifted her up with his hands and hugged her with a nice warm embrace. “You were completely right. I restarted time and nopony, not even you, remembers what happened. Nopony except me! And nopony even got hurt!”

“Mac.” Twilight said as she struggled to speak under Macs constraining grip. “You're going to need to fill the details.”

Mac let her go and shook his head. “Eenope!”

Mac laughed. “It’s too much info to explain in words. It’d be easier just to show you.”

Mac drew Twilight closer and drew her in for a kiss. Twilight was initially caught off guard, as memories from another reality flooded back into her.

“Mac.... I remember” she said, as if recalling a dream. “You… you were amazing. The data I can learn from this. I need to too start taking notice right away.” she paused for a moment then smiled. “After a few more tests that is.”

Mac chuckled. “Anything for my first bride, this time, I’ll make sure not to screw with your memory.”

Mac wanted to keep the loop going forever, but after twelve sessions of experimenting and sharing his powers with Twilight, he knew it was time to stop. Mac & Twilight left the castle completely doped out of their minds like they been having nonstop sex for hours, when in real time only twenty whole minutes had passed since Twilight had teleported them into the library.

Seeing them exit, Princess Luna teleported in front of them and cause the two lovers to jump. “What the hell.” she protested. “You cannot be done.”

Mac nodded. “Eeeyup.”

“I’m really sorry Princess.” Twilight said. “But yeah, technically we’re done.”

“But it’ hasn’t even been a hour.” she shouted. “I’ve haven’t seen action in a thousand years, and I come out here expecting to drown in a river of giant spooge. Thou has deceived us Twilight Sparkle.”

“Don’t worry Princess.” Mac said. “So long as I’m not busy on the farm, I can set up someone on one time just for the two of us. And even if you don’t remember it, you did get your wish. Here let me fix that.”

Memories of all the time she got swept by Macs cum came flooding back into the Luna head. “Oh, sweet me.” she moaned lustfully as her suggestive nethers stated to secrete liquid before the alicorn collapsed on the ground, rolling with ecstasy.”

“Remember,” Mac shouted he and Twilight continued onward “It would be my patriotic duty to share my gift with you your majesty.”

As they left the moaning Luna behind and made their way back, Mac gave Twilight an anxious look. “So, how do we… uhhh… start this harem thing? And how am I gonna explain this to AJ. Telling her I’m marry you would be just as bad as telling her I’m a pervert with creepy fetish powers. I just don’t see it ending well.”

The princess chuckled and reached out to hold Big Mac’s hand. “Just be brave Mac. If we are going to do this, your family will need to know. I’ll contact Celestia to help set up our wedding. After that, any new ponies that join us will just have can just fill out a form.”

Mac shook his head. “If I due marry anyone else, I want them to have a wedding too. Don’t want to pick favourites if this does turn into a harem.”

“That’s really sweet of you say Mac.” Twilight said. “This might get a little expensive though, like I said before, tons of mares have crushes on you. Who knows how many ponies you could end up marrying before this is over.”

“I’m sure it won’t be that many.” Mac said.

As they continued along the path, a nude figure was watching them from behind a tree.

“If only you could see what fate has in store,” Zecora chanted silently. “For soon I shall join you, along with many, many, more!”
