Bulking

Groggily Thunderlane awoke feeling a hard cold surface beneath him. The events of yesterday came flooding back to him, and a disconcerting realization hit him. He felt heavier than before. He opened his eyes to be met with two softball sized cheeks just barely entering his vision. He lifted his arm but found he couldn't move it more than 90 degrees at the elbow or the shoulder. Barely turning his muscle and fat addled head, he saw biceps the size of pumpkins bugling just beyond basketball sized shoulders. Unable to tilt his head down, he nonetheless saw his pecs, now quite soft from a thick layer of adipose, sticking out at least a foot in front of him and resting right in under this thick double chin. Beyond that was a belly that stuck out at least two feet beyond that; plush but firm with a thick layer of muscle surrounded by fat within and without.

He began to speak, "What happ," before noticing his voice was now at least an octave lower than it had been before, a rich bass as thick as his waistline.

A much lighter voice exclaimed, "Oh! I think he's awake."

It was at this point that he realized that he was sitting on an industrial sized scale, the blue crystal walls suggesting he was somewhere inside of the Princess's castle. Twilight entered into the room, well, more of a lab, followed by Big Mac. Wearing a lab coat over her casual clothing, she was carrying a clipboard and... that damned tome.

She said gently, "Don't be alarmed; I've figured out some facts about this tome you received. Also...you appear to now be 1082 pounds, 13 ounces. I've got some good news and some bad news concerning your weight gain."

Thunderlane tried to reach up and rub his head but found himself just barely able to each.

He said, "What's going on? I was told that book would grant my wishes or something like that; I never wanted this!"

She replied, "The magic in here is very, very complex. I can't decipher exactly what it's doing, but it is trying to grant some sort of desire. The thing about desire magic is that it keeps working until the wish is fulfilled. What exactly did you wish for?"

Thunderlane merely sighed, "I'm not sure at this point. The wizard just had me think about what some old junk I had meant to me. I didn't say anything out loud I just...daydreamed a bit."

Twilight replied, "The good news is that the book appears to have entered a kind of stasis where it is content for the time being. The bad news is...I can't reverse it."

Thunderlane's expression froze and he stammered, "Y-you can't? Isn't magic your entire schtick?"

She explained, "Unicorn magic cannot counter higher magic's like chaos and desire. Alicorn magic can... but that would be like using a machete instead of a scalpel. The problem here is that this book is directly tied to your body's state. If I tried erasing the magic with alicorn magic...almost anything could happen to you. For all I know you could disappear completely or blow up or any number of other things."

Thunderlane began to cry, tears pooling in his jowls as they ran down his face. Twilight and Big Mac exchanged looks, and she left the room.

He said, "Don't worry buddy. It's not going to be all bad. Twilight is trying to track down this illegal wish granter and she also used victim reimbursement to pay Rarity to make you a whole new wardrobe."

Thunderlane sobbed, "I just wanted to be a big guy...Now I'm a hulking freak! No one is going to want to even be in the same room with me anymoooore!"

Big mac crouched down, though not very far because Thunderlane's ass had elevated him a foot or so off the ground. He said,

"You are not a freak. In fact, I think you look nice. Now stop crying for a second, because we are going out. I'll help you get dressed."

Thunderlane stifled his panicked state to say, "Go out!? I don't want anyone to see me like this! People will run away or laugh..."

Big Mac said, "Nope. Remember how proud you were at the gym a couple days ago? We're going there and I'm going to help you show off your gains. Nopony should feel bad about how they look, especially not one of my friends. Won't abide it."

Thunderlane sighed and slowly rose to his feet like a force of nature. He found it surprisingly easy despite his bulk. Leg muscles that must have been as thick as trees and as strong as industrial supports lifted his mass; his back, though swaddled in fat and rolls arched with powerful muscle and counterbalanced his ballooned out gut. Once he had risen, Big Mac walked over to a table and unfolded some underwear and shorts that could have held at least six regular sized stallions comfortably.

He got down on the ground next to Thunderlane and said, "Lift your leg."

Thunderlane did as he was told but complained, "I can't even get dressed by myself anymore. What is my family going to think?"

Thunderlane lifted his other leg and Big Mac begain to pull up the new shorts. h

Big Mac said, "Doesn't matter. What matters is that you feel comfortable in this predicament you are in and that the varmint who did this to you is caught. He might be able to reverse since he casted it, I reckon. I promise this won't be so..."

Thunderlane felt a small ripple of pleasure wash over his groin and blushed as he noticed Big Mac must have just encountered his obscenely sized genitals.

He muttered, "Yeah...um...those grew too."

Big mac just laughed, "You do know that as inconvenient as this is there are hundreds of guys who would trade places with you for that change alone, right?"

Thunderlane just sighed, "Yeah, but now it is beyond fitting in any pussy. I have officially outgrown sex mechanically."

Big Mac finished and went over to get Thunderlane a shirt while muttering under his breath, "I wouldn't say that."

"What?"

Big Mac replied quickly as he unfolded the pavilion like shirt, "Nothing. Point is that even if this is a bit extreme not everyone is gonna think you look weird. Some might even find you more attractive than the average guy."

Thunderlane rolled his eyes while Big Mac slid the shirt around his arms, careful to not flex for fear of ripping it,

"Oh sure, what Mare would want a stallion who would crush her and her bed while fucking."

Big Mac blushed slightly but his red coat concealed it from his swollen friend as he murmured, "I know I would"

Pulling the shirt over his head Thunderlane didn't hear the quiet confession, he turned to see himself in the mirror.

"Oh come on!"

The black spandex work out shirt had in bright white letters "XXX-L" on it stretched across his pecs which were barely contained by it, a fair amount of half muscle half fat cleavage showing through the small V neck. It actually was almost able to cover his entire gut, which due to his muscle mass was nearly spherical in shape and jutted out at least three and a half feet in front of him whilst also hanging down to his knees. The shirt ended right above his deep navel and exposed his thick tire of a love handle that wrapped around his waist and formed into a roll on his back. His shorts were similarly stretched but fitting, his beach ball sized ass cheeks held into place and his basketball sized nuts hidden well behind his belly, only just barely visible as the fabric pulled the close. The very top of his ass could be seen from behind and his tail looked tiny in comparison on as it grew out from its position nestled between his rolls.

Thunderlane whined, "Why did Rarity have to put that on the front of my shirt?"

Big Mac shrugged, "Must be the size you're wearing. Lets go hit the gym now big guy!"

As they left the castle they waved goodbye to Twilight as they passed her. Even though he could support his newfound weight he had trouble keeping balance, so He ended up having to hut an arm around Big Mac to keep from wobbling himself onto the ground. Flushed as pink as was visible from beneath his charcoal coat, Thunder Noticed how not a single passerby didn't stop to stare at him. Dozens of eyes all focused in on him suddenly made him feel very, very small.

Big Mac noticed the distress and mentioned, "You get used to it, being the big guy. I started getting looks too when I hit puberty. It's not all that bad, even though your case is a bit extreme. You just gotta own it."

Thunder, despite his nervousness, arched his back a bit more and tried to turn his waddle into a strut.

"I look ridiculous," he thought to himself.

However, he started to reconsider when the looks of disgust or horror changed to awe or shock from the simple change in his gait. Maybe there was something to this?

Arriving at the gym Thunderlane had to actually squeeze the circumference of his belly through the double doors, the small bit of struggle giving every gym goer the opportunity to notice and stare. As he walked in not a one said a thing, before a nasally and obnoxious laughter came from a corner of the room.

"HAHAHAAAA...YOU LOOK LIKE A BLIMP...What happened, eat a dragon for breakfast!? HAHAAAAHAAAA"

This had come from one Caramel, a thinner stallion who had an extremely cut body not unlike that one Thunder had but a few days ago. Thunder started to blush and shrink back before he remembered Big Mac's advice.

Own it.

He lifted his arm from Big Mac's shoulder and lumbered forward with surprising speed. Before the mocking stallion had time to react he was pinned to the wall by a half ton of stallion flesh. Big mac blushed and murmured, "Not quite what I planned..."

Caramel wheezed out from his unfortunate position, "Get off me you fatass!"

Thunder grinned evilly at the sudden feeling of power he had and said, "You should have picked on someone your own size," before turning a bit and saying to the room, "Same goes for you all. Anyone say anything about my weight and I'll break your spine with my ass. Someone spot me while I do bench. And you," he turned back to Caramel and pressed in a little, "Get me some protein shake runt, I'm hungry."

Big Mac just stood there a slightly brighter shade of red, before walking up to Thunderlane as he laid down on the bench.

He said, "That uh...happened fast. Didn't think you'd get your confidence back that fast."

Thunderlane just shrugged and said, "Your advice sounded good so I took it. Size matters and I'm the biggest guy around."

Snowflake and Big Mac stacked at least a half ton onto a barbell and lifted it together so that Thunder could start lifting. The whole of the gym was silent in both fear and awe of the behemoth that Thunder had become. There was only one thing of interest to talk about and it had been made quite clear that you shouldn't. Caramel came back carrying a keg of protein shake.

In between grunts Thunder told him, "Just put the tap in my mouth and open it."

He did as commanded for fear of actually being crushed by the Gym's new apparent alpha and he just laid there benching his own monstrous weight. Such power this body had! Not only could he lift more than any normal stallion could ever hope to, he didn't just direct the attention in the room, he commanded it! He was undeniable, his presence so powerful he could not be ignored. All the strongest guys in town were jumping at his every word because he was bigger, stronger, and could dominate them by throwing his prodigious weight around. This is what it felt like to be listened to! To dominate!

The keg ran empty and Thunder let out a long belch, "UUURRRRAP, go get two more you twig. That was barely a snack for a stud like me. Big Mac, Snowflake, this weight is too easy. Sit on the bar for me."

Caramel ran off to go empty the gym supply of shake and Big Mac and Snowflake merely complied, Snowflake with fear at this sudden change in his friend and Big Mac blushing with certain other concerns about this change...

Thunder was now sweating heavily, a little shake dripping from his chin as two kegs were emptied into his gut. What would have made him bloated yesterday just produced a comfortable fullness that only emboldened his ego. He started to get hard , his now two and a half foot long cock pushing up against the bottom of his belly, visible through the leg of his shorts to any who had been watching, i.e. the whole gym. Grunting with masculine empowered self-assurance he finished his set and then sat up, giving a belch that rattled the room. Sweat soaked through his new clothes and ripped down his belly.

He turned to Caramel and said, "Yo scrawny, you're gonna go help me shower off now. The faster you do the faster I go home."

Carmel was blushing with annoyance at the bossy stallion but decided it best to just comply until Thunder forgave him for his outburst. Strutting with a swagger that set his ass bouncing heartily, Thunder walked to the shower, not noticing the disappointed look on Big Mac's face. He commanded Caramel to strip him down and just leaned against the tiled wall with his arms behind his head as the smaller stallion scrubbed.

He chuckled confidently, "Make sure to get between all my folds. You should have thought about this before you laughed at a guy nine times your size."

Caramel said, quite annoyed, "I don't know what crazy roids you took to get like this. I'm...sorry for laughing. I kinda deserve this but we are not making a habit of this."

Thunder laughed, "Deal. Just had to make a little statement today, you being the easiest target. No no, we're not done yet. You have to get under my belly too."

Caremel rolled his eyes, but as he lifted the titanic gut Thunder shivered at the sudden stimulation, which combined with his power trip sent him over the edge and he emptied the gallons of cum in his nuts right onto Caramel's face. He wiped off the copious spunk as best he could before yelling,

"Oh come on man! What that necessary!?"

Slumping slightly against the wall while breathing heavily, Thunder said, "Sorry, not quite used to this body yet."

Carmel just took the washcloth and wiped as much cum as he could off Thunder's underbelly before standing up and saying,

"That's all you get. Now excuse me while I wash my face with bleach."

Carmel left in a fit while Thunder just laid back against the tile, smiling wide. Big Mac was right. You gotta own your size and it's not that bad. he could get used to this life.

Though he should have had caramel send Big Mac in to help him get his clothes back on. Oops.
