Big (Macro)tosh

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.
