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!?”
