Watching Twilight Sparkle at the front of the classroom, Chrome Shield’s eyes once again shifted to Sweetie Belle’s form in the front row. As much as he tried to concentrate on how the slight syllabic changes of spells had evolved in minute details over the years, his eyes kept focusing on the shimmering glints off Sweetie’s violet and magenta locks.

Suddenly, his attention shifted as a small puff of green smoke materialized in front of him, and a folded note appeared.

A little something from Sweetie Belle he wondered, as he quietly opened it up. But instead of something from her, he found the following message:

To Chrome Shield

Princess Twilight Sparkle wishes to speak with you after class today.

Reading the message made Chrome gulp a bit. It was giving him flashbacks to his schooldays as a young colt. He had a feeling he knew what the discussion was going to be about, but he quickly put away the note, and tried to focus back on the lesson.

As the class concluded and Chrome packed up his things, he looked up and saw Sweetie Belle “bouncing” to the door. He considered rushing down to speak to her, but the wording of the note he had received, made him reconsider.

By the time he had collected his things, Twilight and Spike had already left the classroom. Making his way down the hall to her office door, he knocked upon it a few times. A moment later, a magenta aura opened it, and he saw the Princess sitting calmly at her desk.

“Hello Chrome,” she smiled politely. “Please, come in and have a seat.”

Smiling politely, Chrome accepted her request, and soon found himself looking into his teacher’s face.

“So,” said Chrome, “you wanted to talk to me?”

“Very much so,” said Twilight, her face faltering a little. “Now, I want you to know I have carved out a full hour, so that we can have the proper time to go over what I feel we will need to discuss. Okay?”

“Okay,” said Chrome, “…time for what?”

“Chrome, how much magic experience do you have?”

“Well, it’s something almost all unicorns can use. I’d say I’ve had an…average use of it.”

“I see,” said Twilight, as her horn glowed, and Chrome saw a quill light up and begin to take notes. “And from which of your parents would you say you learned the most about magic?”

“Well, my Mom mostly. My Dad uses magic, but sparingly. He was in the Royal Cadets and wanted to get by on his strengths moreso than magic. He never really used it much around the house when I was younger.”

“Okay, good, good. So, when you heard about my course, what was it that interested you the most about taking it?”

Sweetie Belle’s enthusiasm, thought Chrome, saying in his head what he dared not blurt out.

“Um, well..you,” he replied. “Your reputation being the Princess of Friendship and, an accomplished magic user. Sweetie Belle told me a lot about you helping her when she was younger, and that was why I decided to apply for your course.”

“I’m very pleased to hear that,” nodded Twilight, “but let’s focus on you for now, Chrome. Now when it comes to Advanced Magical Studies, do you feel the course is benefitting you, personally?

There was a short beat, before Chrome continued.

“Well, yeah?” he replied, sweating a bit. “I’m, defintiely finding it very engaging, and learning so much about the magical history of Equestria than what I learned back when I was a foal.”

“And my weekly assignments are helpful?”

“Um, yeah.”

There was a beat as Twilight took a deep breath, and then spoke in a tone that made Chrome gulp.

“So, they’re helpful, even though in our last four morning sessions including this morning’s, you were unable to properly demonstrate for me a technique based around the subject of the assignment?”

“I…I know this looks, bad,” stuttered Chrome, “but I really am learning. I’m not a, a bad student I, just…it’s…hard, is all.”

“I know you’re not a bad student Chrome,” responded Twilight. “When it comes to the magical history portion of my class, your test scores have been…average. Plus, The fact that you are part of the Royal Cadets says a lot about what kind of a stallion you are. I have an older brother who was a member of the cadets some time ago as well, but…I think you need to seriously consider if my course is right for you.”

Chrome could feel what felt like a lead ball forming in his stomach, as Twilight continued.

“I understand this is hard for you to hear, but this meeting is meant to help you. You strike me as an intelligent and good-natured stallion, but your magical performance so far, makes me feel that my course is not benefitting you. Now, in a week’s time, you will be coming up to a point where you can drop my course, and still save your grade-point average. This will mean that you are a ways on from changing over to another course, but it might be in your best interest to consider what I’m telling you. As I said, magic may not be for everypony, and I want to make sure you are applying yourself in the proper areas here at Canterlot University.”

Chrome found it hard to meet Twilight’s eyes. His own eyes darted around a bit, before he eventually looked up.

“I, I thank you for taking this time to meet with me, Princess,” he said. “I’ll give what you said some thought, but…I think I can turn myself around and apply myself better going forward. I really do.”

There was a beat, before Twilight’s enchanted quill scribbled a few more things, and then lay silent.

“Ok,” said Twilight. “That was all I wanted to discuss. Did you have any questions you wanted to ask me? Like I said before, I have a whole hour set aside in case-“

“No-no, it’s alright,” said Chrome. “I really should be going.”

“Well, okay,” said Twilight, as she magically opened the office door. “Take care!”

Once he got out of the building, Chrome took off down the nearest path, trying to get his thumping heart under control.

He knew full well he was struggling in Twilight’s class, but there was also a stubborn sense of pride and embarassment that was coursing through his mind. Deep down, he knew full well that Twilight was most likely right: he could easily think of a few other courses he could have taken and most likely done well in by this time.

However, his thoughts drifted back to Sweetie Belle. If he suddenly disappeared from the class, she might wonder what had happened to him. He could easily chalk it up to being assigned more cadet duties, but would she really buy him dropping such a high-profile class for something like that? Even worse, she was friends with Princess Twilight as well as Spike: what if they told her why he had left the class?

Chrome remembered that today, he didn’t have to report to training for another two hours, and decided he needed to relax and clear his mind…in his own way.

Returning to his dorm room, Chrome threw his backpack in a chair, and drew the shades on his windows. After stripping down, he went into the bathroom and turned on the shower.

A few seconds later, he stepped into the warm water, placed his left hand against the wall, and began to masturbate. His right hand stroked his soft penis, cupping it in his hand as he felt the familiar tingling sensations begin to build, and the soft appendage becoming firmer in his grip.

He stroked it a bit more, before slowly lowering himself into the tub in the shower. Laying against the rear curve of the tub, he folded his legs inward, and once he was settled, he found his thoughts turning to Sweetie Belle. As his memories remembered the image of her breasts filling her dorm room a few months ago, he could feel himself growing again, but in another way.

With his eyes closed, Chrome could feel his penis and scrotum swelling like balloons! Soon, his shaft had grown well beyond the grip of his right hand, and as he imagined his hand gripping Sweetie Belle’s darkened nipple, he found himself rubbing his huge hard-on with the open palms of both of his hands.

Furher down below, he could feel his scrotum soon pushing against the floor of the tub, and the sides of his legs.

After a little while, he opened his eyes, and received a shock!

Thanks to what he’d call “an unorthodox bit of self-experimentation” a couple of years prior, Chrome was used to seeing his cock swell to over 2 feet long when really aroused. What greeted him instead, was a swollen black monolith that appeared to be at least a foot taller (and somewhat wider)! Looking down at the base, even his scrotum seemed larger, as it’s shiny wet surface seemed to be engulfing his enfolded legs, and came close to touching the sides of the bathtub.

As he continued to marvel at the extra swelling of his enormous appendage, a new thought suddenly popped into his head.

As he focused on the middle of his massive cock, a golden aura of magic enveloped his horn, before the same aura wrapped around his shaft. Concentrating harder, he watched as the aura began to move back-and-forth, causing his dark sheath to squash and stretch from the magical movements of the aura.

The sensation was more intense than he had expected! Chrome’s “heavy petting” at this size was nothing compared to the sensations he was currently feeling.

“Why didn’t I think about doing this before?” he muttered aloud.

Closing his eyes, he quickened the sensation of the magical stroking, while his hands reached down below, and began to rub the swollen surface of his sac.

Chrome tried to control himself, but soon found himself moaning loudly, his thoughts again turning to his dream pony, imagining she was giving him a tit-fuck with her enormous white orbs!

Finally, he could hold out no longer, and with a loud groan, he ejaculated in several long spurts of cum. The force was so powerful that each load hit the ceiling, and splattered down onto him.

The stallion didn’t realize this until after his cock was laying spent against his chest, and looked up to see thick, stringy globs of white dripping down onto him.

Aw, nuts,” he sighed.

He figured he’d give himself five more minutes to wallow in the afterglow of his fantasy, before getting the cleaning supplies to deal with his handiwork.

Over the next few days, Chrome tried not to agonize over what Twilight had talked to him about, but found he was unable to just shut his brain off to her conversation. It got to the point where he found himself losing sleep, and forgetting to eat at times. There were even a few incidents during training exercises where his focus wavered, causing him reprimands from his commmanding officer, and smarmy looks from a few of the other cadets.

By that Friday, as Chrome sat in his room going over Twilight’s homework assignment for next week, he had made up his mind about what he would do.

And so the next week, Chrome found himself going down the hall to Twilight’s office, where a small line of students had formed for her weekly pre-class tests. Looking up a ways, he could see a large portion of Sweetie’s chest contained in a fuzzy pink sweater, close to the office door. However, there were 7 students between her and him, and Chrome found himself behind a green-haired stallion with a plaid shirt.

As the line slowly made it’s way forward, Chrome kept reviewing the lesson in his mind. It had called for him to transfigure one object of a few pounds into something of greater weight, but his attempts had yielded nothing so far. Looking along the line, he could see several other students practicing on an object they had brought. One of them was holding an orange, and as he watched, a blue aura engulfed it, and it soon turned into a flower pot! As a few students clapped, a daffodil sprouted from the pot.

A few moments later, Sweetie Belle emerged from room, and saw him in line.

“Hi Chrome,” she said. “All set?”

“Oh, um, yeah,” he smiled. “How’d it go for you?”

“Pretty easy. I turned my makeup compact into a toaster. Plus, it even made toast, which Twilight thought was funny. What do you got planned?”

“Well, I’m gonna turn my coffee mug into a basketball. Sounds, kinda lame, huh?”

“No, everyone has their own preferences. Well I better go. Talk to you later, okay?”

“Sure,” he said as she walked past. “Later.”

Chrome just kept trying to focus and keep himself calm. Soon it was his turn, and he tried to ignore the “concerned blinking” he saw in Twilight’s eyes as he entered.

“Hello Chrome,” said Twilight, as the door closed behind him.

“Hello,” he replied. “I…I know you probably didn’t expect to see me today, but I decided to stick with it. I know you want what’s best for me, and I appreciate your concern, but I thought long and hard about what we discussed, and I know I can do this.”

“Well…alright,” said Twilight, as she magically prepared to take notes. “So, what do you have for today’s assignment, and what will you be turning it into?”

“Um, I have my coffee mug,” he said, pulling it out of his backpack and placing it on a stool in front of her desk. “And, I’m going to turn it into a basketball.”

“Proceed.”

Chrome fired up his horn and concentrated. As he watched, the mug was enveloped in his golden aura, and began to shift and waver a bit. he concentrated harder, and it seemed to swell in size. A smile crossed Chrome’s face as he saw it begin to take on the textures and color of a basketball, before it suddenly shrank in size, and both student and teacher suddenly found themselves looking at a mug made of basketball rubber.

“I can do this,” he said, and focused his aura back on the mug. “I know I can.”

Twilight said nothing, but just watched as the rubber mug again glowed golden.

4 minutes later, Chrome exited the office, as the next student impatiently brushed past him. Going to the classroom door, he saw Sweetie’s head deep in the pages of a book. He quietly entered the classroom and ascended the nearby stairs, making sure she didn’t notice him.

As he reached his usual spot, he set down his backpack as well as the mug...which was textured of rubber, and had deflated.

Author's Note

This chapter has been awhile in the making. It was difficult to figure out the proper direction and conclusion I wanted to take.

The bit about having a conversation with someone about “performance issues,” I wanted to feel very relatable. I had a few college courses that went this way, so I tried channeling that emotion into it.

Up until now, we had never revealed Chrome’s magical ability to grow his equipment, and it felt like a good chance to mention it, let-alone blow off some steam regarding his stressing about what Twilight mentioned. In establishing this story, I wanted to make sure that its universe and rules were not the same as those in The Expansive Romance of Applebloom and Coral Leaf, so we’re throwing out little hints here and there on how some hyper-size stuff operates.

It was nice to also figure out a bit more about just how Chrome’s performance issues are for his grades. Up until a week ago, I hadn’t considered showing.
