In the Crystal Empire, Sunburst had spent most of the day reading dusty old scrolls. He had hardly strayed from his desk as he let all the papers he had already read pile up.

The only thing that got him out of his seat was a knock at the door. He sprung up excitedly and rushed to greet his visitor.

At the door stood the prince himself, Shining Armor. “Huh, only took you a few seconds that time,” he said with a teasing smirk. “And here I figured it’d take you at least a minute or two to respond.”

“Ha ha,” Sunburst dryly laughed. “C’mon in, we got a lot of work to do.”

Shining and Sunburst went into the living room, sitting down on the couch together.

Sunburst clapped his hooves together. “Alright! So, what’s the plan for this year?”

“The good ol’ Chastity Shield spell, obviously.” Shining said, gesturing to his crotch. “Being able to essentially just forget about being horny has been working well so far...Mostly. It’s kinda hard to keep it from swinging around when you can’t get a feel for where it is. Plus it’s still prone to backfiring due to how much magic it takes to keep it up.”

“So...what do you think we can do to fix it?”

“I...have no idea.” Shining shrugged. “If we weaken the effect, then it just makes it more tempting to give in. Not to mention that every little tweak we do only increases the magic load. I have to train some new recruits later on, and it won’t look good if I can’t use my magic.”

“Maybe instead of making alterations, we just start from scratch?” Sunburst suggested. “Think about a solution from a totally fresh perspective?”

“Alright, what can we do to get through this month without blowing it?”

The two stallions sat there pondering how they could last without magically locking up their dicks.

“What if we dulled our libido?” Shining finally spoke up. “If we never get horny, then we won’t have any reason to clop, right?”

“Err, I’m not too practiced in the art of emotional magic. Plus, that could definitely backfire if something went wrong. All our horny desires have to go somewhere, and one accidental release of a week’s worth of horniness would spell certain doom!” Sunburst winced.

“Okay, how about negative reinforcement? Like if our hooves get anywhere close or if we try to magically stimulate it, then it gives us a zap or something.”

Sunburst quickly shook his head. “There are far too many ways to get yourself off without the need to touch yourself. Plus, if we block using magic on it, how are we gonna remove the spell?”

Shining slumped down on the couch. “Yeah, you got a point…”

“Oh! What if we made them detachable?” Sunburst suggested. “We could just store them somewhere safe and then grab them once the month is over!”

“We’d still have to go to the bathroom.” Shining instantly countered.

“Right, nevermind.”

“Not to mention the fact that they’d need to be reattached properly, the looks we’d get walking around with absolutely no junk, how we’d get them back if they got lost, or worse, someone stealing them and then using them for-”

“Alright, alright, I get it! I already scrapped the idea!”

The two sat in silence for a few minutes, racking their brains trying to come up with new ideas, but coming up with nothing.

“...Do we even need to improve the Chastity Shield spell?” Sunburst asked. “I mean, if it works, it should all work out, right?

“It’s true that it works, but it can always be better.” Shining nodded. “The problem is, it takes up a lot of energy to keep up. Any less we put in and it doesn’t work nearly as well. It feels like we can only pick between effectiveness or efficiency...”

Sunburst let out a deep exhale, trying to figure out how to get past their conundrum. “Wait...what if we’re overcomplicating things?” he thought aloud, the gears starting to turn in his head.

Shining raised a curious eyebrow. “What do you mean?”

“Well, the spell right now turns it invisible to everyone that looks. But it only matters to you knowing if you’re hard or not, right?”

Shining nodded in understanding. “Oh, so we could expend less energy making the spell about personal perception instead of a general field one!“

Sunburst clapped his hooves. “Exactly!”

The two stallions got to work, writing down their ideas on how the spell would actually work before they properly cast it. After a few minutes, they were finally ready to start testing.

Sunburst sat up straight, looking down at his flaccid dick. “A-Alright, here goes nothing!” He stuck out his tongue in concentration, his horn aglow with yellow. With a bright flash of light, his genitals had disappeared from his eyes. “I...it worked! I can’t see it anymore!” He nudged the area where it once was, feeling a small, slightly fuzzy sensation as feedback. “Can barely feel it, too!”

“Could’ve fooled me,” Shining chuckled. From his point of view, Sunburst was just stroking his cock, making it slowly rise up.

Shining gave Sunburst’s cock a few test strokes, making sure not to go too overboard, just in case something went wrong. “How’s that feel? Good? Or…”

Sunburst watched as he essentially saw Shining Armor poke away at thin air. “I can feel...something. But just barely.”

“Alright, let me try.”

Shining concentrated on his own dick and performed the spell, smirking upon seeing its success. “Hah, and it didn’t feel nearly as taxing,” he noted, now also fiddling around with his pseudo-invisible dick.

Sunburst looked over to see Shining shaking his cock back and forth, giving him a fresh sense of perspective of what he probably looked like. “So, should we call this a success?”

“So far, yeah!” Shining nodded. “Now this month won’t be nearly as hard!”

“Y-Yeah! Erm...Speaking of hard...” Sunburst gestured towards Shining, noticing that he was at a full erection, already forgetting the fact that Shining would be completely unable to tell.

“Oh, am I? Didn’t even realize.” Shining wiggled his hips in his seat, barely feeling a stir in his loins. “I guess that’s also a good sign though. Besides, you’re plenty hard yourself,” he said, pointing his hoof at Sunburst’s own erection.

Sunburst let out a concerned yelp. “Should we be worried about that? I mean, if it goes off without us being aware of it, would it still count, or-” Sunburst did a double take, his sights fixed on Shining’s shaft. “Is it me, or...did it just get...bigger?” He swore that it grew a whole two inches in length the last time he looked.

“You’re gonna have to tell me,” Shining shrugged. “Though yours is definitely twitching right now,” he said, not realizing that his cock was doing the exact same thing.

Both stallions sat there in silence, staring at the other’s shaft, watching how twitchy and stiff it had gotten, showing no signs of going soft, completely unaware that the staring was part of what kept them hard in the first place.

Though the fantasies of what each of them would do to a cock that large certainly didn’t help matters either.

“...Should we...go back to the drawing board?” Sunburst asked, finally managing to concentrate.

“N-Nah, I’m sure this’ll be fine for the month...Probably.”

If your chastity shield lasts longer than 6 hours, nice.
