The Solution

Shining Armour frowned into the cup of chamomile tea that sat cold before him. He studied his reflection on the surface of the still liquid. Blue eyes with dark circles underneath, two-tone blue mane, a horn on his forehead typical of a unicorn, and shaggy white fur. Many would call him handsome. He would call himself ‘not enough’.

Sitting across from him was Sunburst, a light orange furred unicorn stallion with bespectacled blue eyes, wild dark orange mane, an ever present scraggly goatee, white markings on his lower legs and nose, and wearing his blue star patterned cloak. He clacked his hooves together nervously in front of him and eyed the equally cold cup of chamomile tea beside him.

They were both in the central living room of Sunburst’s personal residence. Every available wall space and much of the floor was claimed by bookshelves heavily laden with historical texts detailing a wide range of topics.

Doors leading to a bathroom and kitchen could theoretically be found near the sections of the shelves dedicated to plumbing and a history of cooking, but, like most of the civilizations noted within the various tomes, could be considered lost.

A cordoned off area behind a poorly hung moon patterned curtain was the dedicated space for both Sunburst’s bed, which Shining knew was drowned in a sea of woolen blankets as per Sunburst’s obsessive need for warmth at night, and his newly built alchemy station, which was primarily used for Sunburst’s potion making that he picked up after stumbling across an old collection of potion recipes wrote by Mage Meadowbrook.

He had also repeatedly ‘forgotten’ to inform her of the existence of said text.

Sunburst found himself in this situation when Shining had arrived suddenly at his abode not ten minutes prior. He had burst through the door, swore for the first two minutes after a rather abrasive ‘hello’ then sat angrily glaring holes into the table.

Sunburst had made tea to give Shining time to gather his thoughts and talk when he was ready, but Sunburst was quickly realizing that if he was going to figure out what had soured his friend’s mood, he was going to have to speak first.

“So,” Sunburst began, “How are you?”

Shining Armour looked up from his attempt at glaring through solid crystal. He glanced over Sunburst’s body. Slender, but with some pudge due to his sedentary profession. An average sized stallion, Shining noted with resentment.

Shining himself was closer to the size of a mare barring the bulky muscle he had put on from long years of training in the guard. A fact pointed out to him on more than one occasion.

Said fact had never bothered him before until recently.

“You know,” Shining said conversationally, “There are a lot of downsides to dating a stallion the size of a push cart.”

Sunburst was startled to hear his friend finally speak. “Oh, are there? I thought everything was good with your beau?”

“This isn’t about Flash,” Shining replied, “This is about stupidly huge ponies and how being with one when you barely reach the average size of a mare is a pain in the flank.”

Sunburst coughed awkwardly. “Right, so you have a problem with, uh, big ponies then?”

“Yes. A lot in fact.” Shining snorted. “Like how they hog all of the bed space when they’re asleep and eat enough food to feed five full grown ponies.”

Sunburst nodded awkwardly in agreement. He levitated his cup of tea in the yellow glow of his magic, took a sip and frowned. “The tea is cold,” he declared, “Should I warm-”

“And it’s even worse when you’re the dominant one in the relationship,” Shining interrupted, “You choose to date a big dumb horse and they turn out to just want to follow your every command.”

Sunburst set his tea down and pushed it to the side. “Okay, I suppose not then. Every command?”

“Every command,” Shining repeated, “And despite being the supposed ‘sub’ he’s so demanding. ‘Put a collar on me, Shining’,” Shining mimicked in a mocking nasally voice, “‘Tie me up and rut me until morning, Shining’.” Shining snorted. “Stupid big hot submissive ponies.” Shining raised a hoof toward Sunburst. “Not Flash by the way.”

Sunburst fought to keep his gaze level as he felt his cheeks burn, “Of course, it isn’t. Also, I thought you liked that Fla-, sorry, big submissive ponies were super demanding?”

“Well, yeah,” Shining said in a tone of voice that suggested it was an obvious fact, “But I also like to complain about it too. Adds to the whole roleplay you know?”

“I don’t.” Sunburst shook his head. “I really don’t.”

“It’s alright, you don’t need to.” Shining leaned back and tapped his hooves idly on the table. “Now, let’s say, hypothetically, this is about Flash.”

“Oh?”

“I would say he’s been a huge pain in my flank as long as I’ve known him,” Shining growled.

“Oh,” Sunburst said helplessly as he had no idea where Shining was going with this conversation.

“Known Flash for over twenty years and been his colt friend for over a decade. My trusted Lieutenant for the same duration as I’ve been Captain of the Guard in both Canterlot and the Crystal Empire. I’ve been well respected as both.” Shining frowned. “Except I also happen to know what my subordinates say when they think I can’t hear them.”

Sunburst winced already having a general idea, “Dare I ask?”

“That it’s nice Flash Sentry is so tolerant of taking orders from a toddler,” Shining stated bitterly, “Or some variation. Years of effort and respect boiled down to a joke about my size.”

“I’m so sorry, Shining,” Sunburst said, “For what it’s worth, I think it hardly matters what size you are in the face of your many accomplishments.”

“Oh, I know.”

“You do?” Sunburst asked quizzically.

“Oh, yeah. I haven’t given a single fuck about what anypony says about my relationship with Flash since High School when I first realized I was always going to be a third of Flash’s full size.” Shining paused. “I mean a third of a big pony’s size.” Shining sighed. “Sorry, Flash’s size. Honestly, I don’t even know why I tried to talk to you about this as if it wasn’t about him.”

“It’s fine, Shining. You’re hardly worse than Starlight who likes to discuss issues that her ‘friend’ has.” Sunburst and Shining both giggled. “So just to be clear, you aren’t bothered by what others say about you?”

“Nope.” Shining shook his head. “Flash loves me as I do him. I won’t let some strangers dictate my relationship of over a decade with him.”

“That’s great.” Sunburst frowned. “But if everything is fine on that front, what’s the problem?”

Shining bit his lip nervously. “Can you keep this between us?”

“Of course, Shining. I wouldn’t even dream of telling somepony else about something that you told me in confidence.” Sunburst grinned. “And I do mean that literally.”

Shining smiled at the small joke, but soon settled to a downturned expression. “So, the other day I decided to try something new to add a twist to our evening romp.” Shining slid his tea cup back and forth with his hooves nervously. “Flash was laying on the bed and hadn’t seen me, so I decided to try and mount him while he wasn’t paying attention.”

“Oh no, Shining did you-”

Shining’s eyes widened and he waved his hooves in front of himself, “No! It was consensual. It was something Flash and I had discussed previously since he loves it when I take charge in the bedroom like that. No, it was bad but not that kind of bad.”

“Then what was wrong?” Sunburst asked, “That seems like it would be-”

“He didn’t notice.”

Sunburst blinked in confusion. “I don’t think I’m following. What’s wrong with that?”

“I mounted him, Sunburst. I got up to the hilt and he didn’t notice.”

“Oh, Shining.”

“Once, I got over the fact that Flash didn’t even realize I was rutting him we ended up having the worst conversation of my life,” Shining groaned, “Turns out shortly after Flash was done his massive growth spurt back in high school, he found out that I was too small for him. He’s just been getting off on the roleplay and my pleasure from the intercourse.”

Sunburst winced.

“He stayed with me this long because he loves me. There’s a part of me that’s happy because it means he really does care for me, I’m not just a warm body to him.” Shining hung his head. “But, the fact that I haven’t been able to sexually satisfy my coltfriend in over a decade is kind of devastating.” Shining buried his face in his hooves. “Fuck, do you know how embarassing that is?”

“I can’t imagine.” Sunburst awkwardly rubbed one hoof along his opposite front leg. “Have you tried-”

“Toys?” Shining interrupted with a growl.

Sunburst gulped. “Well, yes.”

Shining glared at Sunburst then looked away with a huff. “Yeah, we have. But toys for us were supposed to be a supplement, not the only option.” Shining growled in frustration. “I know using toys isn’t the worst thing, but it doesn’t change the ego hit I’m taking from knowing my own dick isn’t good enough.”

Sunburst looked at Shining in sympathy before becoming thoughtful. “Do you want to break up with Flash?”

Shining slammed his hooves on the table, spilling both his and Sunburst’s tea onto the floor. “What? No! I’m not breaking up with the love of my life because we hit a road bump in our sex life!”

“But your size issue is still a problem, right?”

“Well, I mean.” Shining lowered himself back down with a thump. “There are toys like you said. I’ve been browsing stores all this week looking over possible options, but it's just frustrating because the root problem is me and I can’t change anything about it.”

“Well.” Sunburst stood up and made his way over to his alchemy bench behind the poorly hung curtain Sunburst wouldn’t let Shining fix. “If it’s just size that’s the problem...”

Shining looked at Sunburst curiously as he watched him browse through several cabinets filled with various colourful potions. “What are you looking for?”

“Well, as you know I’ve been recreating some ancient potions from Mage Meadowbrook’s time period.” Sunburst stopped. “Don’t tell her about that.” Sunburst continued his search through the cabinets. “And I happened to have made a potion last month that might - Aha! Here it is.”

Sunburst returned to the table carrying a bright blue potion in his magic. It was contained within a wide bottom flask stoppered with a large cork. Tied around the bottle’s neck with a string was a label. Shining couldn’t make out the tiny scrawl written on the paper.

“A growth potion,” Sunburst declared as he gently placed the potion in the centre of the table.

Shining peered closer at the concoction and tilted his head in confusion. “A growth potion? Like for plants?”

“For ponies.” Shining shot up with a shocked expression on his face. “This would solve your size problems.”

“Isn’t this incredibly hard to make?”

“Yes, and before you try to say something silly like how I shouldn’t waste a rare potion on your bedroom problems, you’re my friend, Shining.” Sunburst smiled warmly. “If a potion is capable of assisting you with your problems, then I’ll gladly give it to you.”

“That’s really kind of you, Sunburst. I’ll skip the ‘I’m not worthy speech’ then.” Shining eyed the potion warily. “I don’t suppose-”

“I could explain the specifics?” Shining nodded his head. “Of course. I wouldn’t have you drink some strange magic potion without explaining the details. That’s just irresponsible.”

Sunburst cleared his throat. “Now, when you drink the potion you need to be thinking of Flash while you do it so the potion knows the ‘target size’. Over the course of one week, you will slowly grow to be somewhat bigger than him. Nothing happens the first day as the potion will be warming up, but you will be very sore.”

“Why does it not activate instantaneously?” Shining asked.

“To give your body time to adjust between growth stages.” Sunburst smirked. “I presume you prefer to have your muscle tissue and bones stay internal?”

Shining gulped and nodded his head.

“I presumed so,” Sunburst said, “Now, I will have a reversal potion ready for you to consume should you not like the size change, however, you can’t take it until the full effect is complete one week from when you drank the potion.”

Shining mulled over the information he had been given. “Are you sure there are no additional side effects?”

“Besides the muscle, height, and dick growth?” Shining’s face flushed. “No, I guarantee it. I personally tested the potion a while back out of curiosity and I assure you it works very well.”

Shining gave a coy grin. “Is that why you told me you were busy two weeks ago?”

Sunburst chuckled nervously. “Yes, well I didn’t really want anypony to know I had attempted to see what it felt like to be the same size as Princess Celestia. For the record, I found being that tall is not something I enjoy.”

Shining snorted. “I can’t even imagine.” Shining blinked and a look of apprehension crossed his face. “Wait. If I become bigger than Flash then I won’t have to.”

“This is just an option, Shining,” Sunburst explained gently, “You don’t have to do it, if you don’t want to. There are other options that you've already looked into and even then I know Flash loves you too much to leave you over a problem like this.”

Shining stared at the potion for a moment longer before taking a deep breath. “I know, but even if we move past this, I’m always going to be thinking about how inadequate I am in the back of my head. It’s worth it to at least try.”

“Shining, you’re not-”

“I know Sunburst,” Shining interrupted, “But right now that’s what it feels like and a potential solution has presented itself. I’m not one to shy away from a challenge.”

Shining took the potion in his magic and lifted it closer to his muzzle. He uncorked the flask and took a whiff. Faint mint. Not the worst smell he’s ever been subjected to.

“Bottoms up.”

Shining chugged it in one go as he thought about Flash.

“Ugh.” Shining stuck his tongue out in disgust. “Tastes like sweaty stockings.”

“How would you even know what that tastes like, Shining?” Sunburst asked.

“You know damn well how I know that.” Shining glared. “Don’t kink shame me, Sunburst.”

Day 1 (Mon): Growing Pains

Shining Armour woke up with a loud groan and his eyes closed. His body ached worse than the day after he had been slammed into the ground by an earth pony during sparring.

He cracked open one eye to peer at the analog clock hanging just above his bedside table. It read six in the morning. More than enough time to prepare for the day before reporting to the Crystal Palace for work.

He stretched under the bundle of blankets he was swaddled under and winced from the resulting cracks. Sunburst hadn’t been kidding when he told him there would be some ‘growing pains’ from the potion.

He grabbed the blankets in the magenta glow of his magic and tossed them to the other side of the enormous bed he slept in. Shining abruptly remembered that it was shared. He rolled himself over with a grunt of pain to apologize to the other occupant of the bed.

“Oh, shit. Sorry Fla-” He cut himself off as he remembered that Flash was sleeping downstairs on the couch.

As he had everyday since ‘the incident’.

Shining released a weary sigh and lugged himself up into a sitting position despite the protestations of his body. He twisted and stretched as much he could to mitigate the pain before turning towards the empty side of the mattress.

He touched the permanent depression in the bed with a solitary hoof where Flash normally slept. The emptiness was really starting to get to him.

They’d had several conversations already and Shining was getting sick of Flash punishing himself for something neither of them could help.

He felt a pang of loneliness as he withdrew his hoof. This distance was half the reason Shining so readily agreed to consuming the potion in the first place. He would do anything just to have his big goofball back.

At least starting tomorrow, the potion would begin to take effect and Shining could move towards permanently remedying the problem. Assuming he even enjoyed being bigger than his partner.

A problem to resolve at a later time.

Shining gently lowered himself onto the rug covered crystalline floors. He sucked in a hiss of pain as his body responded with several severe twinges of pain. Work was going to be Tarturus.

He edged along the bed past the door leading to the ensuite bathroom and past a large dresser. The surface of said dresser was covered in mementos.

His eyes lingered on a few of the more important ones. A photo of Shining sticking his tongue out to the camera next to a grinning Flash from their first date in Canterlot. A signed letter of gratitude addressed to both of them for their assistance in the repelling of the Changeling invasion at his sister’s wedding to Cadance. A letter of promotion to Captain of the Crystal Guard from Her Empress Cadance.

Shining smiled as he recalled each memory attached to each. He was grateful to have those times with the pony he had chosen to be with.

Shining trotted up to his destination at the far end of the room: a full wall length mirror directly across from the bed. Flash always teased Shining for being egotistical. He had a habit of checking himself out when he went down on Flash from behind.

That was also only half the reason he liked the mirror. He actually had wanted it to always be able to see Flash’s rather expressive facial expressions. He could always tell if he was doing a good job when Flash’s tongue was lolling out and he was staring straight ahead with a blissed out glaze over his eyes.

He scowled bitterly as he reminded himself that some of those expressions could have been faked. A sentiment that was souring his previously good vibe from the momentos.

Shining looked over his reflection. Smaller than the average unicorn in stature with a bulky, wide build from long continuous years of training in the guard. A regimen he never let up on even when he became more of a desk jockey as Captain. He noticed that he was fully sheathed, an irregularity considering his libido, but may be a small mercy as Shining didn’t feel like confronting the root of his current stress that early in the morning.

He was 4.5 inches, if he was being generous and rounding up. Well below the average penis size, a number he knew after a somewhat embarrassing trip to the Crystal Empire Library. For unicorns at least. He didn’t even hit the smallest range for earth and crystal ponies and pegasi tended to be on the lower end of the unicorn range.

Having of course seen every part of Flash, he knew Flash was somewhere around the lower limits of an earth pony. Not a fact he took comfort in at that moment.

He shook his head and turned towards the open doorway leading to the main foyer of the house. He felt an overwhelming pang of loneliness and, despite the aching pain in every step, trotted through the arch towards the pony he knew could fix it.

Shining found himself in the living room. A piano and several guitars dominated a corner of the space with a storm of sheet music spread about it. Another corner was taken up by floor to ceiling crystal shelves overflowing with tabletop systems, fantasy novels, and horror stories; the latter of which Shining was planning to use as inspiration for several upcoming campaigns.

Every remaining amount of space was packed with shelves, small trinkets and knick knacks accumulated by two stallions with ample spending money, strange tastes, and low self control. Shining still stood by the purchase of the 1/100th to scale model of an elder dragon from his favourite campaign in ogre and oubliettes that hung from the ceiling using crystal made cables.

Shining smiled as he remembered that the model was secured as strongly as it was because Flash occasionally liked to use it as a hammock.

Speaking of Flash, Shining turned his attention to the massive couch in the centre of the room that stood just below a large bay window. Said window was currently covered by two massive orange and blue striped curtains that only allowed through the barest of light. Normally, it was to keep random passerby from seeing two horny stallions in the middle of their early morning workout. Recently, it was to allow the pony on said couch to sleep easier.

With an avalanche of soft, colourful pillows underneath his head was his colt friend Flash Sentry. He had a light orange coat, two massive wings, and dark blue mane swept back into a wavy crest. Shining suppressed a snort of amusement as he noticed that Flash’s side burns had grown out again. Shining always joked that it made him look a decade older than he was and like some wannabe street thug.

Flash was turned away from Shining which only served to emphasize his massive bulk. Many attributed Flash to be akin to an Earth pony with wings plastered on and those same ponies typically claimed he couldn’t fly.

They normally changed their tune shortly after Flash launched into the air. Mainly from their new position on the ground where they usually ended up after being hit by the blowback generated by a few flaps of Flash’s wings.

Shining was well acquainted with every ridge and crevice along Flash’s body and had long since marked him as his with a neverending assault of kisses, and hickies over many years.

Among other things.

Flash had some interesting tastes in sex and Shining was always happy to provide. Even if some of the more outlandish requests ended up delegated to the ‘nope’ part of the closet.

For the moment, Shining didn’t want sex; he wanted intimacy. That meant cuddle time.

Shining laid upon his side on the couch with his hooves pressed into Flash’s back. He had tried multiple times in the past to spoon his colt friend and that had never worked out before as he could only get halfway up Flash’s back before running out of leg length. He didn’t need to further his internal annoyance about his size.

Shining closed his eyes. He could hear Flash’s steady heartbeat and felt his consciousness fade as he was lulled by the steady, comforting rhythm.

“I’m sorry.”

Shining opened his eyes and perked his ears. “Stop apologizing.”

Shining felt Flash curl up into himself. “But-”

“No buts,” Shining interrupted, “This isn’t something you or I can help. It is what it is.”

Flash rolled over in place, careful to not squish Shining with his massive bulk. Shining looked up to Flash’s blue eyes. They were red rimmed, and had dark circles under them. Evidently, Flash was having as terrible a time with this situation as Shining was.

“But I made you question whether you leave me satisfied.” Flash sniffled. “You do, and I mean that. It doesn’t matter if you aren’t the best fit.”

“We’ve had this conversation already and you continue to have poor word choice.”

“And you still look disappointed every time you look at me,” Flash replied.

“I’m not disappointed with you.”

“I know you aren’t.”

They were both quiet. Flash sniffled. Shining cupped Flash’s face with his hoof. Flash nuzzled into the contact.

“I don’t care about my own satisfaction,” Flash said.

“I’d rather you be more selfish about that.”

“Not at the expense of your happiness.” Flash scowled.

“So at the expense of yours is better?” Shining replied evenly. “How do you think that makes me feel, Flash?”

Flash was silent.

Shining released a tired sigh. “Look, we both hate this, but the rift is what’s really killing me right now.”

“I know,” Flash mumbled, “I’m just really mad at myself for causing this.”

“You did nothing wrong, Sent.” Flash smiled at Shining’s private nickname for him. Shining smiled back before taking a breath to prepare for the next piece of information. “I’ve taken action to remedy our problem.”

Flash’s eyes widened. “Shining-”

“It’s not dangerous,” Shining interrupted, “It just takes a week to achieve its full effect.”

“Shining-”

“You don’t have to worry about it affecting our jobs or how we feel for each other.” Shining raced on.

“Shining,” Flash said in an exasperated tone.

“Hopefully, it will-”

Flash placed a hoof over Shining’s mouth. He had a peeved expression on his face. “Can I talk now?”

Shining nodded his head.

Flash removed his hoof. “Look, I trust you. I know you wouldn’t do anything to bring harm to yourself or me and you would have taken every precaution for… ?”

“A potion.”

Flash expression flattened. “... A potion. Really, Shining?”

Shining fidgeted as he avoided Flash’s face.

Flash sighed. “No, it’s fine. I trust you. I really do. However, I don’t want you to do something that you aren’t comfortable with for something so unimportant as my sexual desires.”

“I assure you Flash, I want to do this,” Shining replied, “And your sexual desires aren’t unimportant. If this works then we can move past this easily, and if I feel uncomfortable I can always reverse the effects.”

“As long as you’re sure.”

“I am Sent.” Shining smiled at his beloved. “I love you.”

Flash smiled back. “I love you too, Amour.”

Shining basked in the afterglow of feeling the love radiate off of his coltfriend before his thought turned to a more lecherous proposition.

He smirked. “Wanna do something fun together before work?”

Flash’s ears perked and Shining felt a slight breeze from the fluttering of Flash’s wings. It was short lived as shortly after Flash’s ears pinned to his head and a pained expression crossed his face.

“Another time, Shining. I’m not really feeling it right now.”

Shining knew it was because of Flash’s internal guilt. He chose not to push the issue as he knew that would only end in another useless conversation. Besides, Shining could have more fun tomorrow when the changes started happening.

“Okay, Sent.” Shining leaned forward and kissed Flash on the cheek. “Breakfast then? Of the non-usual variety?”

“If you mean hay bacon and mangos instead of a liter of your cum in my mouth, then yes.” Flash smirked. “Let’s do that.”

Author's Note

You may consider this the end to the Foreplay. We get started next chapter.

Day 2 (Tues): Working the Horn

Shining woke up laying in bed buried under several layers of blankets. He mumbled incoherently to himself before bringing himself onto his hooves whilst still covered. He pulled the covers around himself using his his magenta magic to keep the warmth in - something he wouldn’t need to do if a dumb pegasus would hurry up and return to their bed - and stepped offthe edge of the mattress.

He felt the floor come too quickly, and stumbled forward onto his belly in surprise.

He groaned as pain radiated from where he had impacted the floor. Despite the rugs, it was still solid crystal and it had hurt. He furrowed his brow and tried to piece together why he had even stumbled in the first place.

It’s not like the floor or his bed could have changed height during the night.

He widened his eyes in realization as the answer became obvious.

The growth potion.

Shining threw the blankets back onto the bed, scrambled to his hooves ignoring the sharp pain from the too quick motion, and galloped to the bedroom’s mirror while fighting against a measure of onset vertigo.

He stood before the mirror and inspected his body. He was definitely taller. He would most likely meet Sunburst’s eye level, though, unlike Sunburst, he was definitely more built.

He looked thicker, but still within the same proportions as he had been before. His barrel was definitely wider and the width of his shoulders gave him some cause for concern about fitting through doorways in the future if the trend continued. He was also struck by the fact that he was now certain that he had a heavier build than Flash, which he hadn’t thought he had before.

He felt an urgent heat rise from his nethers at the thought.

Shining sat back on his flanks - he noted that they cushioned him more than they had before - and stared down at his penis as it flopped out of his sheath.

His balls were noticeably larger and about the size of oranges as per most unicorn stallions. His dick was on the rise and Shining was keen to assist.

He placed his right hoof at the base and flinched from how sensitive it was to his touch. He stroked slowly up and down biting his bottom lip to keep from crying out from the pleasure exploding through his system.

Sunburst had never noted anything about being more sensitive, but Shining wasn’t going to complain.

As he stroked, his cock leapt to its full length. At a glance, Shining measured it to be around 6 inches in length, potentially 6.5. Shining bit down harder on his lower lip as his cock surged to its full hardness and smacked his belly.

Shining leaned back using his front hooves to support him. His cock pulsed and quivered. He didn’t think he’d been this turned on in over a week.

Shining grabbed his cock in his magic and stroked it lightly. He panted from the surge of pleasure that coursed through him. He squeezed hard at the base and a glob of precum quirted from his tip and dribbled down the side of his length.

He stroked up the shaft, past the medial ring, and flicked his flared tip with a small pulse of magic.

Shining clenched his jaw tight. He had never been this sensitive and it was driving him wild. He didn’t know if he hoped this would be a permanent side effect or wear off after the week was up.

He returned his focus to the task at hoof. He stroked up and down his length using his magic. He started slowly then pumped faster as he felt his balls clench down and ready to blast their load up his shaft.

He glanced towards the open archway and abruptly clamped down on one end of his shaft with his magic. His penis engorged, attempted to break through the narrow space, then eventually ebbed back to its origin when it failed to do so.

Shining winced from the dull throb that took over from his still rock hard member, but he reasoned there was no point in wasting an orgasm that was better off shared with his other half.

Shining brought himself back onto his hooves and winced as pleasure shot through him as his cock brushed against the rugs on the floor. The contact left a short trail of precum from where it connected.

He cast a quick spell to clean up the mess - a very helpful suite of spells for two stallions with a high libido provided by Cadance - and trotted to the living room.

He found Flash where he had been before. He was curled up on the couch atop a mountain of pillows with his back turned away from the bedroom door. Shining moved forward, and cuddled up against Flash’s back with Shining’s painfully erect cock squished between them.

“You’re making a mess on my back,” Flash said.

“You should do something about that,” Shining replied.

“I don’t feel like it.”

“Then I’m going to continue making a mess of your back.”

“Then I suppose I’ll just have to shower before I leave for work.”

Shining scoffed. “As if you didn’t always have to do that after our mornings together.”

Shining scooched up the couch closer to the back of Flash’s head. He buried his snout in Flash’s mane and blew air on Flash’s right ear. It flicked in irritation. Shining waited to see if Flash would react. When he didn’t, Shining nibbled on the tip. Flash squeaked at the contact.

“Quit it,” Flash whined.

“Make me,” Shining replied teasingly.

“I can push you off this couch,” Flash threatened.

“And possibly injure me?” Shining scoffed. “Yeah, nice try, Sent. you would never do something that could get me hurt.”

Shining nibbled on Flash’s ear some more. Flash moaned and buried his snout deeper into his heap of pillows. Shining smirked as he noticed Flash lightly thrust forward into the couch.

“Pent up?” Shining teased.

“Shut up,” Flash replied petulantly, muffled by the pillows.

“You know I have just the cure for such a thing.”

“Oh, jerk off.”

“That’s the idea, yes.” Shining was rewarded for his efforts by a red tinge at the tip of Flash’s ear. A universal sign of Flash’s arousal and embarrassment. “You seem to like that idea.”

“No,” Flash mumbled, “I’m just.. Out of sorts today.”

“You mean horny.”

“I mean out of sorts.” Flash growled.

Shining stopped. He buried his snout back into Flash’s mane and took a deep breath. He smelled like the ocean. A trait apparently shared by all Vanhoover born pegasi as told by his coltfriend whom Shining thought just used a secret stash of shampoo.

It was always comforting.

“I’m sorry,” Shining said, “I didn’t mean to be pushy. I just missed you.” He smirked. “Was masturbating and thought of you in the other room.”

Flash groaned and lifted his head up enough to glance back at Shining. “Way to ruin a perfectly good moment.”

“It’s a talent.” Shining frowned. “But I do really miss you. It’s not the same without you next to me.”

Flash’s head flopped back onto the pillows. He took a deep breath and rolled over to look at Shining face to face.

Shining also noticed that Flash wasn’t the only thing facing him. Flash’s fat fourteen inch cock was jammed up against Flash’s belly, rock hard and already leaking precum like a faucet.

“Fine.” Flash scowled. Shining thought it was cute. “I’m horny. Really horny. Happy?”

“Very.” Shining grinned and rubbed his cock up against Flash’s. Flash moaned from the contact and Shining had to fight back the urge to join him. “Though not as much as little Flashie down there.”

“Little Flashie has been pent up,” Flash replied, “I just haven’t wanted to deal with it because-”

Shining placed a hoof voer Flash’s mouth. “No, we are not dealing with your internal self loathing right now. I am horny. You are horny. We are both lonely and haven’t had a good rut in over a week. We are doing this.”

Shining removed his hoof. “Okay. Yeah, no point talking about this again. I’ve missed you too much to think about that right now.” Flash grinned sheepishly. “I’ve also missed you rutting me.” He bit his lower lip. “Captain.”

Shining grinned. It was reminiscent of a shark. “Well, well, well, soldier. Are you in need of another training session?”

Shining pressed his cock in closer to Flash’s which caused both to throb at the contact. Flash gulped and pinned his ears back against his head. His tail wagged lightly as he nodded.

“Yes, Captain,” Flash replied, “I’ve been in a slump and need your special attention.”

Shining leaned in close to Flash’s ears. “Remember the safe words?” Shining whispered.

“Tangerines and Citrus,” Flash said confidently, “Three knocks on any surface if I can’t speak.”

“Good, stud,” Shining whispered before pulling back and taking on a commanding tone, “Now, soldier since you’re so out of practice...” Meaning no anal since neither of them had done enough or any preparation, “How about we put that mouth to work, soldier?”

Flash burst to his hooves and excitedly trotted in place. Shining chuckled good naturedly and stood up. Both stepped off the couch.

“Attention!” Shining commanded.

Flash planted his hooves, brought a wing up and saluted alongside his cock which slapped against his undercarriage.

“In position, soldier.”

Flash dropped to the floor and pressed his rump back against the couch. His tail and wings wriggled excitedly in anticipation of Shining’s dripping cock.

“Eager today aren’t we, soldier?” Flash snorted excitedly as his wriggling intensified. “Let’s get started then.”

Shining leapt up and planted his front hooves on the couch just above Flash’s head. He had a momentary thrill out of how much easier it was with his new height.

Shining guided his dick to hover just in front of Flash’s snout. He gave Flash’s muzzle a light rap with his penis and left a small glob of precum behind. Flash whimpered longingly, but knew to wait for permission before latching on.

“Get to work, soldier,” Shining ordered.

Flash immediately latched onto the flared tip of Shining’s penis and suckled at the dripping globs of precum. Shining shivered from the pleasure. He was right to wait as it felt even better than using his hooves or magic.

After a few more moans and sips at Shining’s cock, Flash began working the length of Shining's shaft down his throat. Shining enforced every bit of his willpower to not burst on the spot from the sight.

Shining’s gasps of breath became more ragged as Flash worked his way from the tip, past the medial ring and stopped an inch short of the base.

Flash furrowed his brow in confusion. Shining noticed, turned off his dominant mindset, and looked down at his partner in concern.

“Is everything okay, Sent?” Shining asked worriedly.

Flash worked his way off of Shining’s dick and released his cock with a pop leaving a small trail of saliva behind.

“Is your dick bigger?” Flash asked, “Also, I hadn’t been paying attention before, but you seem… taller.”

“That’s normal,” Shining replied easily.

Flash frowned. “Don’t you gaslight me, Shining Armour. We’ve been together for years and I assure you I am very in the know on your measurements. You are not normally this size and you’ve told me yourself that growth spells are exceptionally dangerous.”

“Sorry, Sent. Let me clarify. Me growing is the normal part.”

Flash widened his eyes in sudden realization, “Oh, the growth potion. Yeah, that makes sense.” He did a quick once over Shining’s body and blushed. “Yeah, that potion definitely grew you quite a bit for one dose. Are you happy with the results?”

“It’s not done.”

“Pardon?”

“It’s not done,” Shining repeated, “The potion isn’t done until the end of the week, so I still have about five days of growing left.”

“Five days of-” Flash shivered in pleasure.

Shining tilted his head and noticed a puddle of precum forming underneath Flash. He grinned maliciously.

“Oh, what have we got here? Is our little soldier getting heated up about his Captain’s size?”

Flash whimpered in response and nodded his head.

“Well, soldier. Your Captain is more than willing to let you taste his massive cock as much as you want.” Shining leaned forward with his dick jutting forward toward Flash’s face. “Take it all in while you can because by the end of the week you might not even be able to.”

Flash licked his lips once before lunging forward. He took in the tip of Shining’s cock and worked it into his mouth in record time. Flash pinned his ears and back moaned around Shining’s 6 plus inches of cockmeat. Shining gasped out from the sensations caused by Flash’s mouth.

“Good, soldier. Now, hold still while I get ready to rut your face.”

Shining leaned away from Flash bringing his penis to sit with just the tip grazing the back of Flash’s teeth. Flash whimpered and tried to follow after it until Shining grabbed his snout in his magic and forced him back into place.

“Patience, soldier,” Shining sternly told him, “You’ll get what you want soon enough.”

Once Flash had eased up, Shining released his snout from his magic. Shining then ensured his hooves were firmly planted on both the couch and floor before thrusting forward sharply back into Flash’s mouth.

Flash groaned in bliss as his head was pushed back from the force of Shining’s cock. Shining eased back to just past his medial ring then thrusted again. He repeated the action slowly, then pumped faster as he got into his rhythm.

Flash stayed latched onto Shining’s dick and started grinding his own dick against the rug covered floor.

Shining felt a build up as his balls clenched down and he heard Flash’s breath hitch. A sign that he was also ready to burst.

“Off,” Shining commanded gruffly.

Flash popped off of Shining’s dick, but stayed close. Shining gripped the base of his penis in his magic and started roughly stroking it as fast he could to drive his orgasm forward.

Flash lifted his rump off the ground and used a wing to start stroking himself in tandem with Shining. He opened his mouth to prepare for the oncoming cum flood rising in Shining’s shaft.

Shining cried out as he felt his cum hit his cock flare and explode forward. Rope after rope streamed into Flash’s mouth and across his face drenching him in a pool of Shining’s cum.

Shortly thereafter, Flash grunted and a similarly massive puddle of splooge appeared underneath Flash.

Flash looked up to Shining and made a show of licking the corners of his muzzle. He swallowed what he had managed to lick up and panted heavily with a glazed over expression.

“Thanks for the training session, Captain.”

“Anytime, soldier,” Shining replied.

Flash’s expression became more lucid. “Shining, I-”

“Are you about to apologize or belittle yourself?” Shining cut in.

Flash bit his lip. “No?”

“Good, because I don’t want to hear it.” Shining smiled softly as he looked down on his beloved. “Look, I know you feel bad, but this seems to be working. I’m not going to be mad at you because you like the results.” Shining smirked. “Though based on your response, I’m enjoying the results it has on you more than myself.”

Flash’s face flushed. “Happy to serve, Amour.”

Shining brought his hooves off the couch and landed just in front of Flash. He kissed Flash directly on his cum covered snout and enjoyed the taste of his own salty cumshot.

“Let’s get cleaned up, Sent.”

Flash grinned before frowning, “Ah, this might be bad.”

“What?” Shining asked.

“Well, the potion definitely made you more sensitive and hornier than before, right?”

“Glad to see you noticed that too. Yes, it does.”

“Okay, that might be a problem since I need to leave home early and won’t be back until the dead of night tomorrow.”

“What do you mean?”

“New recruit training starts tomorrow and I got told to cover the first day. Remember?” Sentry smiled sadly.

“Ah, fuck. You’re right.” Shining groaned. “And I have those historical records to assist Sunburst with tomorrow. How in Tartarus am I supposed to focus if this is how horny I’ll be with no morning relief?”

Flash grinned mischievously as he got up on all four hooves. “You know,” Flash started, “You still haven’t thanked Sunburst properly for the potion. You could always give a proper thanks with a rockhard salute.”

“Still pushing for me to jump on that opportunity, eh?”

“Yes, especially right now that my Amour cannot be properly cared for by myself. Besides, he’s a good friend and an especially good looking one.” Flash showed a lecherous grin. “I’m sure my dear Captain is looking for some excellent new recruits.”

Shining bit his lower lip in thought. “I’ll think about it.”

“All I ask for,” Flash replied cheerily.

Flash stood up onto his hooves and trotted past Shining while caressing Shining’s chin with his own tail. Shining found himself following after Flash’s flanks as they bounced lightly with every one of Flash’s steps.

“Now, come on, Captain.” Flash gave Shining a taunting smirk over his shoulder as he trotted towards their bedroom and the attached en suite bathroom. “It’s important to cool off after a hard training session.”

Shining grinned. “Of course, soldier. Lead the way.”

Day 3 (Weds): Wizard Juice

Author's Note

Apologies for the late release. Hope you all enjoy.

Day 3 (Weds): Wizard Juice

Shining snapped his eyes wide open and threw the covers off himself using his magic as quickly as possible. He leapt off the bed and raced to the mirror excited to see what changes were brought on through the night. He already knew his cock had grown significantly based on how long his morning wood was as it slapped against the underside of his stomach.

As he reached the mirror and skidded to a halt, he took in his new appearance.

He now stood well over the average unicorn and on eye level of some smaller earth ponies. He’d put on a heaping pile of muscle onto his body that was thankfully still proportionate to his build. Striations criss crossed his muscular limbs and every movement caused the veins to bulge.

Shining hopped in place and grinned giddily as he saw his form lightly ripple from the dense muscle of his body.

He had to admit, he was thoroughly enjoying this.

Shining felt his cock tense underneath him. He glanced downwards and his grin turned lecherous. He let himself fall back onto the floor and stared at his rigid cock.

It now stood erect at 8 inches. The girth was beginning to rival that of his front legs back from before he drank the potion. It pulsed and sputtered precum from the flare to Shining’s immense pleasure. He rubbed at his hefty balls that had grown past the size of oranges and moaned as he felt tingling bliss from the soft touch.

He continued massaging his balls as he stroked his member with his magic. His tongue lolled outside of his mouth as a small trail of drool dripped from the corner. He flicked the tip of his dick and cried out as a massive dollop of precum spurted from his flare head and splattered against his chest.

His back leg kicked out, impacted against the mirror and formed cracks along the previously smooth polished surface. He relished in the strength behind it and felt another surge of pre shoot out.

Despite his lustful haze, he cast a quick spell to repair the mirror returning it to its previous state - a second spell acquired from Cadance in the discovery of Flash’s kicking habit during sex.

With a massive force of will, he stopped magically touching his dick and got back up onto his hooves carefully to ensure it remained untouched so as not to trigger an early release. He used his magic to grab a cloak from the nearby dresser and slung it over himself to hopefully remove any obvious signs of his erection from the public eye.

Thinking back on what Flash had suggested the night before, Shining readied to leave for Sunburst’s home.

He had a hot nerdy unicorn to seduce.

“Ah! The personal diary of Sergeant Forward Guard. Place that one just before Archmagus Luminary’s ‘Observations of the Final Battle of the Crystal Empire Assault’.” Sunburst waved a hoof in the general direction of its place within the rapidly growing timeline. “It was a personal account of the night before the Twin Diarch’s final confrontation with Sombra when they were requesting aid from their Allies. Very important.”

Shining suppressed a sigh of frustration. “Right, very important. Will do, Sunburst.”

“Thank you!” Sunburst called out as he reviewed another stack of old tomes collected from the Crystal Palace.

Shining hefted the rather heavy diary of Sergeant Forward Guard onto his back - An original based on the crystallized coating on the cover - and dropped it into its appropriate place in the makeshift timeline.

Said timeline was a series of several dozen massive books lined in a row on what used to be a large table. Shining had originally thought the table would have been big enough, but he had clearly underestimated Sunburst’s ability to hoard books.

Thankfully, the table was made of crystal and anchored to the floor so it wouldn’t collapse under the weight of several tons of paper.

They had been organizing the pile for over half an hour since Shining had arrived. He had just enough time to drop his cloak to the floor before Sunburst had grabbed him and set him on the task of moving books around.

Somewhat degrading that Sunburst had asked for his help less due to his knowledge and more due to his usefulness as a book cart.

What made matters worse was that Shining had been unable to get in a single word between Sunburst’s frantic scrambling. This would normally not have been a problem, but he was still harboring a major hardon and every sway of Sunburst’s hips was causing it to bounce off of his belly.

At the rate this was going, he was either going to have to succumb to the worst case of blue balling in his life or request access to Sunburst’s bathroom for a private wank session.

Since he refused to allow the aching of his loins to continue and was unsure if he could locate the bathroom amongst the shelves, Shining decided he would need to be more direct.

“Oh, how delightful! A journal from one of Sombra’s nursing maids. I wonder what wonders are contained within-”

“Sunburst,” Shining interrupted, “Would we be able to pause on the book sorting and speak for a moment? We have all day to do this and we could take some time to perhaps say a simple good morning.”

Sunburst paused in his ramblings and giggled nervously. “Ah, I got carried away again, didn’t I?” He placed the nursing maid’s diary onto a nearby pile that Shining was certain Sunburst wouldn’t remember doing. “First off, good morning. Secondly, what did you want to talk about?” Before Shining could reply, Sunburst rambled on, “Oh, you probably want to talk about the growth potion. Any ill effects?”

Shining was going to approach the subject with tact but his rather demanding cock decided for him. “I’m overly sensitive. Practically ready to cum on a single stroke.” Shining trotted closer to a now red faced Sunburst until he was only a few inches away from him. Shining smirked. “Forgot to mention or thought it would be fun for me to find out?”

Sunburst nervously adjusted his glasses with his magic as Shining looked down on Sunburst. A vantage point Shining was learning to greatly enjoy.

“W-Well, that was my mistake. I wasn’t sure if the effect would have propagated in another pony.” Sunburst coughed awkwardly. “I am fairly sensitive by default myself, so I couldn’t be sure if it was the potion or I was simply suffering from...” Sunburst looked down. “A rather long dry spell.”

Shining nodded his head. “Understandable, I suppose. Just for, well, research purposes, are you interested in knowing the details of how I’vebeen affected?”

“I-I suppose in order to have an u-up to date log of the effects, it is important to know of said effects.”

Shining smirked and hung his head to be level with Sunburst. He moved forward. Sunburst noticed and moved back until he bumped into the bookcase behind him. He stopped short of Sunburst’s muzzle.

“Well, for research purposes, I feel like I’m on the edge almost every second of the day. Just rubbing up against something sets me off and you don’t want to know how much willpower it takes not to accidentally discharge in armour.” Shining paused for a moment to let the words mariante in Sunburst’s thoughts. “Do you know if the effects are permanent?”

“They aren’t,” Sunburst reassured despite his increasingly flustered demeanor. “The hyper sensitivity seemed to ease up by the time the transformation completed, which for you would be Sunday.”

Shining took in Sunburst’s nervous form and decided he needed to check in. “Am I making you uncomfortable?”

“No.” Sunburst flinched. “Yes! I mean-” He bit his lip. “You’re with Flash. This seems a little inappropriate considering the circumstances.”

“About that. Flash and I were talking about our future. Specifically in terms of our relationship.” Shining’s eyes took on a mischievous glint. “After I coated his face in a layer of my cum.” Sunburst shivered in place. “Flash brought up an old idea.”

Sunburst gulped. “O-Oh, Did he? What was the idea?”

“He wants me to start a herd. Says he can’t stand the thought of hoarding me all to himself.” Shining leaned in close to Sunburst’s ear. He whispered, “Want to guess whose name came up when we were discussing our first member?”

Shining heard Sunburst’s breath hitch. “Probably another guard considering your shared career. Maybe… What was his name, Spearhead?”

“A good choice, but somepony to think about later. We were actually thinking more of a close friend outside of the guard. Who’ve known us both for a long time. Big nerd.” Shining spoke in a honeyed lust filled voice, “A personal fantasy of mine if I were to be honest.”

“Y-You couldn’t possibly mean me?” Shining grinned. “It’s me? Y-You want- I mean- I don’t- Why?”

“You’re a good friend to me and the love of my life.” Shining kissed Sunburst’s collar bone which caused him to shudder at the contact. “I enjoy your company and adore how much of a nerd you are.” He removed Sunburst’s glasses with his magic, placed them on a nearby book pile, and kissed him on the neck. “You're incredibly intelligent.” He kissed Sunburst’s cheek. “And I couldn’t imagine somepony better.” He stopped just short of Sunburst’s lips. “How could I not be attracted to you?”

Sunburst looked back to Shining while breathing heavily with his face flushed and his eyes wide in shock. Shining, despite the neediness of his groin, waited for Sunburst to initiate. There would be no point if Sunburst was unwilling.

Sunburst leaned forward towards Shining’s lips. He paused just before they touched. He took a deep breath then latched onto Shining’s lips with his. Shining soon felt his probing tongue and allowed quick entry.

Shining pushed up against Sunburst who groaned around their locked lips. He removed his lips from Sunburst after a moment then kissed along the nape of Sunburst’s neck. Sunburst moaned in pleasure at Shining’s attention.

“Do you know about the practice of safe words?” Shining inquired as he nipped at Sunburst’s neck.

“Words to say when things become too much, right?” Sunburst replied.

“Correct. Now, repeat after me: cantaloupe, evergreen, or three knocks on any surface.”

“Cantaloupe, evergreen, or three knocks on any surface,” Sunburst repeated.

“Excellent.” Shining praised before he took a bite at the spot he had been kissing.

Sunburst cried in ecstasy as he lurched against Shining. Shining smirked as he withdrew leaving a bright red hickey behind.

“And now, you’re mine,” Shining decreed.

Sunburst licked his lips nervously as he looked at Shining with a lustful gaze. He bit his lip then spoke in a high falsetto. “My-My Lord Gleam. Should we be doing such things in the keep at this late of night? Will not our fellow adventurers hear of our foray together should we continue?”

Shining stared at Sunburst in open confusion. He racked his brain for what Sunburst was trying to do then eventually clued in that he was using his tabletop character’s name Gleaming Sword.

Oh, Shining would have fun with this.

“S-sorry, Shining. I can’t believe I said that. We can-”

Shining put a hoof to Sunburst’s mouth. “Worry not, Arch Bishop, for I can assure you with my dome of silence that our compatriots shall be none the wiser. And to question if this be the time, how ridiculous a notion. We are in the night's embrace after a long battle. Now is the best time to indulge in carnal pleasures.”

Sunburst’s eyes lit up. Shining removed his hoof. “But my Lord, what of the watch? Will they not happen upon us?”

“Mayhaps, but they are not due to relieve us for a few hours yet,” Shining forced himself to adapt the more sophisticated tones of the Canterlot nobility. “Now, Arc, my illicit lover. Shall we abscond somewhere more comfortable so you may attend to me?”

“Of course, my Lord. I would love nothing more.”

Sunburst yelped as Shining moved himself underneath Sunburst’s legs and hoisted him onto Shining’s back. Shining ignored Sunburst’s cute protestations as he cantered to Sunburst’s bed and dropped him onto the pile of blankets up against the wall.

Shining hefted himself up and planted his front hooves on the wall above Sunburst’s head. He waggled his cock just in front of Sunburst’s face.

“Now, Arc, be wary to take your time. We wouldn’t want this to end too quickly, would we?”

“It would be tragic, My Lord, to waste such a splendid experience.” Sunburst leaned closer and breathed onto Shining’s cock causing him to moan lightly. “What magnificence you present to me. I cannot think of a better cock to pleasure.”

“You flatter, Arc, but flattery does not yield attention and physical pleasure unto myself.”

“Of course, My Lord. I am simply overcome by such a sight. Truly glorious in its stature.” Sunburst licked along Shining’s full length eliciting a moan of pleasure. “Such unmatched length and girth, how could I not be utterly enthralled?”

Sunburst sucked on the flared tip and was rewarded with another moan. Sunburst fondled Shining’s balls with his magic and sucked down to Shining’s medial ring.

Shining fought back against the surge of cum roiling at the base of his shaft. No need to erupt before the main event.

“For one who claims such little experience, you seem to know well your way around a shaft.”

Sunburst released Shining’s cock and gave him a lust filled expression. “I have spent many a night in the mage’s tower experimenting with spells best discussed somewhere more private.”

Shining grabbed his cock in his magic and pumped it lightly to keep it hard as Sunburst continued to fondle his balls.

“A topic I believe we should most certainly come back to. I have the utmost interest in such illicit spells, Arc.”

“But of course, My Lord, however I would like to focus on the topic at hoof. A powerful, virile stallion such as yourself is a riveting view for one such as I from my position under you.”

Shining felt his cock flex in his magic. He clamped down on the tip as he stroked to ensure he wouldn’t accidentally fire off early.

“How could one resist such a strong, powerful, big stallion such as yourself. Such strength of limb and broad of barrel. Unmatched prowess, elegance in every movement. I am turned by the mere sight of such a gorgeous specimen of a stallion.”

Shining felt himself flex. Hard. He was enjoying the play of words more and more as it went and was making serious considerations to have Flash learn to do the same.

It was also time to see if Sunburst was up for a rut.

“Arc, you have most certainly attended to me well. Shall I reward you for your efforts? Pierce you with my sword so that you may be filled by such a magnificent specimen of a stallion as you decree?”

In answer, Sunburst flipped himself onto his back with his head against the wall. Shining licked his lips as he gazed upon Sunburst’s 7 inches of cockflesh on full display. It was rock hard against his stomach and spurting a fountain of precum.

If Shining’s dick wasn’t already ridgid, it was then.

“I see we are eager to please my little wizard. Shall I-”

“Shining, this is super hot and I want to do this roleplay again,” Sunburst interjected, “But I really need you to grab the lube hiding under the blanket on the right side of bed, and rut me hard.”

Shining grinned. “Right away, Sunburst.”

Shining used his magic to search for the bottle and, after some scrounging, lifted the container up to just above his own cock. He squirted a hefty dollop of lube onto his dick, dropped himself from his position on the wall, and rubbed it along the shaft with one of his front hooves.

He dropped another dollop of lube onto Sunburst’s waiting ponut. Sunburst moaned from the contact as Shining spread it around with his second hoof.

Shining planted his hooves on either side of Sunburst’s head. He lined up his cock and pressed inwards until he hit the firm resistance of Sunburst’s hole.

“Ready?” Shining asked.

“Yeah, Shining. Fill me up.”

Shining kissed Sunburst on the lips. He felt Sunburst loosen up and press against Shining. Once Shining was sure he was relaxed, he pushed his cock into Sunburst’s waiting hole and buried the first inch of his cock in.

Sunburst tensed underneath him, but moaned around Shining’s mouth in pleasure.

Shining waited for Sunburst to untense before shoving in another half inch of cock. Shining continued this pattern until Shining’s balls slapped against Sunburst’s flanks.

“You okay, Sunburst?” Shining asked as he nuzzled him.

“Yeah, I’m fine, Shining. Are you going to thrust now?”

“Only if you’re ready.”

“Then do it. Make me yours Shining.”

With his permission granted, Shining pulled back to his medial ring and, after ensuring he had solid footing, shoved forward. Sunburst gasped in pleasure as Shining impacted into him.

He started slow, quickly building up a strong rhythm as he thrusted over and over into Sunburst’s needy hole. Before long, Shining felt his cock engorge and a familiar feeling take over.

“I’m going to cum, Sunburst,” Shining gasped out through his lust addled haze.

“Do it, Shining. Right inside me.”

Shining felt the pressure build as he panted from the intense feelings of pleasure running through him. Sunburst quickly wrapped his own cock in his magic and was soon fit to erupt.

Shining cried out as he exploded into Sunburst’s ass. Gallons of cum flooded his insides. Overflow spilled from Sunburst’s hole and soaked into the blankets on the bed. Sunburst soon followed with his own cries as he coated both of their undercarriages and the underside of Shining’s chin.

Once finished and ignoring the mess they had created, Shining collapsed onto Sunburst. He nuzzled into his mane and breathed in the faint scent of old books. Sunburst, equally exhausted, basked in the afterglow.

“How are you feeling, Arc?” Shining teasingly.

Sunburst groaned. “Great until you reminded me of that. Ugh, what was I thinking?”

“Not straight if that was what you were wondering, though for what it’s worth I, as the Lord of the Paladin Order, found that quite hot.”

Sunburst snorted. “Of course, you did.” He maneuvered himself to be more encapsulated by Shining’s embrace and sighed in contentment. “So, a herd, huh?”

“Yes, and after this I’m greatly considering it.” Shining smiled. “Though only after the changes are finished. I want to know if I’m comfortable with myself and Flash before I start adding more into the mix.”

“Good, good. Well, if you do decide to start that herd, you can consider me willing.” Sunburst kissed Shining on the underside of his jaw in a spot not covered in splooge. “You’re here for the day?”

“Helping you organize books. Theoretically.”

“Well, we have the entire day as you said earlier, and I, quite frankly, am in no rush. Would My Lord Gleam care for another round?”

Shining grinned widely as he felt his cock begin to stir. “His lordship would very much like to, yes.”

Day 4 (Thurs): Nip and Tuck

Shining woke up with a yawn. He attempted to lift himself off the bed, but instead flopped back down onto his pillow with a groan.

Yesterday had been exhausting. Every time they sorted a stack, Sunburst would give Shining a look and they would trot off to his bed. Each time they rutted they dove into a different roleplay and scenario, usually in the tabletop setting they both played.

Shining had been particularly fond of the prince and dragon scenario in which Shining roleplayed as a dragon inspecting his ‘hoard’.

It was fun, but Shining’s mind was overcome by a fog of exhaustion. He moved his hoof down to confirm that his dick was rock hard. Again. He was surprised considering how many times he ejaculated the day before, but he assumed it was just a side effect of the potion.

He stroked his length and winced as he confirmed that he was still hypersensitive, but not as badly as he had been yesterday.

He was tempted to get out of bed to inspect the changes he had inevitably gone through that morning, especially as he was certain from his quick grab that his dick was definitely longer, but was more content to stay in bed and take the morning slow after yesterday’s fuck fest.

Shining released another yawn and rolled over to his other side coming face to face with a massive orange lump.

He widened his eyes in surprise when he saw Flash’s sleeping form. He was turned on his side towards him and snoring softly with his wings tucked behind him.

Flash yawned and opened his eyes. On seeing Shining, his ears perked up and a lazy grin spread across his face.

He leaned forward and kissed Shining on the snout. “Good morning, Amour.”

“You’re sleeping in our bed again,” Shining replied dumbfounded.

“Well, it is ‘our’ bed, Shining.” Flash giggled. “You sound as if I’ve never slept here.”

“That’s-” Shining sputtered, “I mean, I know, it’s just you’ve been sleeping on the couch so many nights that I’m just surprised.”

“I got lonely last night when I returned from my shift and realized that I could remedy that by simply sleeping where I’m supposed to.” Flash’s ears pinned to his head. “Assuming it’s okay for me to still sleep here.”

“Yes, of course it is.” Shining scooted closer to Flash until their muzzles were almost touching. “You’re always welcome in my bed, Sent.”

“Good to hear because I don’t know what I would do if you told me to leave.”

“Flash, I would never tell you that.” Shining moved his head forward the remaining distance to kiss Flash lightly on the lips.

Flash smiled. “You’re such a flirt in the morning, Amour.”

“I can’t help myself when a hot pegasus drops into my bed unannounced.” Shining smiled back. “You don’t think I could resist your gorgeous face for even a moment, do you?”

“Hm, no. I don’t think you could.” Flash’s grin turned sleazy. “So, how did things go with Sunburst yesterday?”

“We fucked. A lot. And organized books, but that was definitely becoming secondary as the day continued. Also, it turns out that Sunburst is super into roleplay.” Shining scooched forward an inch more to have both their noses touching each other. “How do feel about a threesome between Lord Gleaming, Arch Bishop, and Pan Pipes?”

“Can I bring a flute?”

Shining laughed. “For what?”

“Immersion,” Flash said with a serious expression, “If we roleplay we do it all the way or none of the way.”

“Can you even play the flute?” Shining asked.

“No, but I’m sure I can figure it out while you and Sunburst spitroast me.” They both giggle snorted. “So, I presume Sunburst is interested in joining our herd?”

“He is, and I’ve already decided to follow up on that once the potion finishes this Sunday and I decide on whether or not I’m reverting the effects.”

Flash bit his lower lip nervously. “And you’re interested in starting a herd?”

Shining kissed Flash on the nose which caused him to smile. “Yes, I am. The idea has grown on me since.” Shining pondered for a moment. “Why are you so invested in starting a herd?”

“I’m a lonely stallion, Shining. I want to be surrounded by others who love me.” Flash giggled mischievously. “Plus I want to get railed by as many studs as possible.”

Shining groaned. “You’re terrible.”

“No, I’m not. I just date this amazing stud of a stallion and can’t help but feel bad that I have him all to myself.”

“So, you want to whore him out to every hot stud in the Empire?”

“And be thus surrounded by a harem of the hottest stallions on offer?” Flash snorted. “Who wouldn’t want that?”

Shining laughed. “Alright, you horny bastard. Come here.”

Shining kissed Flash on the mouth who quickly reciprocated. As they kissed, He began grinding his cock up against Flash’s who moaned in response. He was happy to note that Flash was as hard as he was.

“Feeling frisky?” Flash asked.

“Always and clearly you as well,” Shining replied teasingly.

“I admit to nothing.”

Their kissing took a turn towards lust and they moaned into each other. An idea occurred to Shining. He had always wanted to do it, but couldn’t due to their size difference before. Now that he was bigger, Shining thought he could pull it off.

He scooted as close to Flash as he could, braced his left shoulder against the bed, and pushed himself up with his front legs wrapped around Flash. Flash turned upwards onto his back with Shining on top of him.

Flash leaned away from their lip locked embrace. Shining continued his affectionate assault by nibbling gently on Flash’s neck.

“You couldn’t do that before,” Flash commented.

“No, I couldn’t. Enjoyed it?”

“Very. Do that anytime you want, Amour.”

“I’ll keep that in mind.” Shining raised his head to be hanging just above Flash’s. “Want to know something even better?”

“I can’t imagine anything better than with you on top of me. Heavily on top of me,” Flash said in surprise. “You must weigh like three times what you were before.” He mulled the thought over. “Which is hot.”

Shining snorted. “Glad to see where your focus is right now. No, the best part is this.” Shining thrusted forward which caused their cocks to rub together.

Flash’s eyes widened in shock. “Wait, I hadn’t noticed earlier, but you can kiss me and fuck me now?”

Shining smirked. “Not quite big enough to rut and kiss you yet, but I can definitely rub our dicks together.”

Flash used his wings to throw the blankets covering both of them to the floor and looked over Shining’s appearance.

Shining was thick. He was muscular before, but his increased size showed just how big the muscle covering his body actually was. He was also decidedly more rounder than before with his previously flat stomach jutting out more into a barrel shape.

Flash was under no illusions that any part of that was fat.

His limbs were thick with corded, striated muscle. Flash looked past Shining’s shoulder to see his flanks and almost burst on the spot from the sheer size of them.

More pressingly, and grinding up against his own cock was Shining’s now ten inch penis. His balls were bigger than Flash’s with them approaching the halfway point to soft balls and Shining was really packing on the girth. It was leaking a fountain of precum from the head and mixing with Flash’s own pool of pre-splooge on his stomach.

Shining was almost at Flash’s size and it was making Flash incredibly horny.

Shining flicked Flash’s tip with his magic and grinned when he whimpered. “Somepony seem to be enjoying themselves.”

“Can you blame me? There’s even more of my coltfriend to love and he can now kiss me and rub my dick at the same time.” Flash gave a half lidded stare. “Only thing to make this better is if my big stud would be willing to rut me over and over again.”

“A good idea for sure, but I have something else in mind for this morning.”

Shining moved his rump forward until his cock head was lined up with Flash’s. He pressed down heavily, pinning Flash’s dick between his and Flash’s chest. Once secure, Shining grabbed both their dicks in his magic and began to stroke up and down both their lengths.

Flash’s face flushed as he squirmed underneath Shining. He whimpered, panted and whined as he felt pleasure race through him with every stroke. Shining had to continuously flex to ensure he wouldn’t fire off immediately with how turned on he was.

As he stroked along both their cocks, Shining glanced at Flash's wings and noticed that the feathers were in disarray.

He smirked.

“Hey, Flash? Have you been preening properly?”

Flash froze underneath Shining. “Y-Yes?”

“Are you lying?” Shining asked teasingly.

Flash looked away from Shining. “N-No.”

“Really?” Shining moved his head closer to several feathers that were out of alignment at the base of his wings. “Because this looks like it hasn’t been properly preened and I happen to know you have some trouble with that.”

“Okay, yes. I’m having trouble preening at the base of my wings,” Flash whined. “But it’s not my fault! I’m big and inflexible. It’s hard.”

“Good thing you have a generous coltfriend then, right?”

“Wait, no, Shining!” Flash said in a panic, “You know how sensitive I am when- Ah!”

Flash cried out as he released a massive spurt of precum from his cock onto his chest. Shining had opted to ignore Flash’s protests and simply start straightening the feathers along the base of Flash’s right wing.

“I know, and I enjoy it every time.”

“Shining!” Flash whined.

Ignoring Flash’s whining, Shining continued to straighten and clean Flash’s feathers with his tongue. All the while, Flash squirmed in pleasure from the dual sensations of having his cock stroked and wing preened.

On the last feather, Shining blew on the joint between Flash’s wing and back causing his cock to shoot another load of precum. Shining nuzzled Flash’s chin.

“Now for the right wing, Sent.”

“No,” Flash protested, “I-It’s too much, I’m not going to-”

Shining interrupted Flash with a long kiss on the lips. “Hygiene is important which includes proper wing care.”

“But do you have to make it this erotic?”

“Yes, now try to hold on for the next… five minutes while I preen your other wing.” Shining gave a predatory grin. “You wouldn’t want to cum before me would you?”

Flash whined piteously.

Shining began the same process on Flash’s left wing. Shining could feel Flash’s balls clench and his cock engorge as it readied to fire off. Despite the odds being against him, Flash held on. If only barely.

Flash had an impressive amount of stamina and control, but Shining also knew all of his weak spots. As he finished preening the last feather, he maneuvered himself to the base of Flash’s wing and licked at the connecting tendon sending a shiver through Flash’s ripped body.

“Shining, stop. If you do that-”

“You’ll cum?” Shining finished with a cheeky grin.

Shining increased the speed of his stroking. He forced himself to hold back as he felt Flash tense underneath. Knowing he had him, Shining grabbed the sensitive spot on Flash’s back with his teeth and pulled.

The effect was instantaneous. Flash cried out Shining’s name and his dick expelled a font of cum across both his and Shining’s chest.

Flash collapsed against the bed panting heavily. “I hate you.” He kissed Shining on the snout. “I also love you, but for now I hate you.”

Shining smirked. He cut out the magic around both of their cocks, and then, to Flash’s bafflement, got off the bed and onto his hooves with his cock still rock hard underneath him.

“What are you- Ah!” Flash yelped.

Shining grabbed Flash in his magic and tossed him onto his back. He trotted into the connecting bathroom ignoring Flash’s flustered protests and dropped him gently into the shower.

Flash stared at Shining with open confusion. Shining dropped his rump onto the shower floor with his cock still rigidly upwards. The stall was a tight fit for both stallions and soon to be impossible as Shining kept growing.

Shining planted both rear hooves on either side of Flash’s flanks and angled his cock towards his face.

“Suck it,” Shining commanded.

Flash rolled his eyes and, not wanting to waste time, downed Shining’s cock to the base in a single fluid motion. He choked a bit on the last inch, but still managed the feat.

It was the hottest thing Shining had ever seen.

“Good stud,” Shining said as he gently rubbed his hoof through Flash’s mane who hummed in satisfaction.

Flash worked Shining’s cock, pumping up and down. Shortly a familiar pressure built. He looked down and Flash gave a nod of confirmation as best he could with his face stuffed full of dick.

Having no more barriers to his inevitable climax, Shining let his cum surge up his shaft and explode into Flash’s mouth as he cried out. Flash downed the gallon of cum in one go with only a few small trickles dripping down the length of Shining’s shaft.

Flash came off of Shining’s dick with a pop. “Thanks for the breakfast, Amour.”

Shining laughed. “Your welcome, Sent.” He used his magic to turn on the hot water in the shower. “Now, let’s get cleaned up since we do have to go to work soon.”

“We do.” Flash grinned as he was doused under the above faucet head. “Can’t wait to see the looks on the other guards’ faces when you walk in today in your tight armour.”

“Hah! Yeah, that will be a good surprise.” Shining smiled affectionately down on Flash. “Love you.”

“Love you too, Shining.”
