Silver's Cocky Birthday

One Week Later

By the time Silver Bell’s birthday finally arrived, Scootaroll seemed rather content about how well everything was going. Even though he was worried his plans for his coltfriend would freak out Buck or Spike, neither of them were too quick to pass judgement, or even spill the beans to the birthday colt. The potion itself took a few days to properly brew (mostly to ensure the results would be temporary), but Apple Buck pulled through to give Scoot the vial the night before Silver’s birthday. And since Silver’s birthday party wasn’t until that weekend, Scootaroll was determined to take advantage of the free weekday the two could share together during his actual birthday.

Both Silver and Scoot made sure to have the day off from their jobs, so they were able to spend the entire day together in Ponyville. Unlike a lot of their other endeavours together, Scootaroll treated his coltfriend like an absolute gentlecolt without any suggestive undertones. Whether it was taking him out to lunch at his favorite bistro, getting him a complimentary cupcake at Sugar Cube Corner, or even buying him a cute jacket he was eyeing as they walked past a clothing store, the pegasus made sure that Silver Bell had a wonderful birthday outing. Even though it was obvious that the twinkish unicorn knew something was up, there wasn’t any moment during the day where Scootaroll saw his coltfriend’s smile go away.

By the time the day reached mid-afternoon (and the sun was already close to setting due to the winter weather), the couple finally began to head back home to their apartment. Silver Bell knew that his partner had something planned, but Scootaroll’s knowing smirk didn’t open up in the slightest about it. Instead, the pegasus kept himself close to his mate while they were both bundled up, and gave Silver a caring nuzzle underneath his chin. “Sooooo… did you have a good time today?~” he asked in a kind and optimistic tone.

Silver Bell was quick to nod his head enthusiastically, and lit up his horn to hold up the shopping bags latched in his magic aura. “Absolutely!” He then laid a pert and loving kiss atop Scoot’s forehead, and then gave a nuzzle of his own as he added, “Seriously, this has been an awesome day! It kinda sucks that Buck and Spike couldn’t be here, but I couldn’t have wished for a better way to spend my birthday with you~”

Scootaroll smiled even wider upon hearing Silver’s genuine statement, and leaned in to give the unicorn a proper kiss on the lips. Silver’s bags nearly dropped when his magic flickered in surprise, but he was quick to keep his presents up while returning his kiss to Scoot. By the time the two finally finished, their shadows were already reaching outward a far distance to point them towards their home. And as they continued to walk through the fresh snow with high spirits, Scootaroll waited until their apartment complex was in sight to lean in close to Silver’s ear.

“Just so you know,” he whispered in a more sultry-sounding hiss, “I have something reeeeaaaallllly special I wanna show you when we get inside~”

Silver Bell’s smile turned to a Cheshire-like grin as he jolted from that remark, and tried his hardest not to run up the snowy steps. He wasn’t sure if Scootaroll was planning a proposal, or another night of spellbindingly awesome sex, but either option would’ve made Silver happy nonetheless. When the two finally made their way up to their apartment door, the unicorn was starting to shiver in his boots with anticipation; meanwhile, Scootaroll was mostly shivering from the cold as he fidgeted with the key. “Ugh… s-stupid gloves…”

“I got it!” chirped Silver Bell excitedly as he grabbed Scoot’s key with his magic, and unlocked the door in less than a second. Silver rushed into the apartment with gusto and tossed his shopping bags on the couch, before he used his magic to eagerly remove his winter boots. By the time Scootaroll finally got himself inside and closed the door, his coltfriend was already out of his winter clothes. “Here!” he shouted with an antsy smile as he used his magic to help Scoot out of his coat and boots too. “Lemme get that for you~”

Scootaroll knew that Silver was likely only helping him so he could get to his gift faster, but he didn’t seem to mind the additional help. When both ponies were finally out of their snow-powdered attire, Scoot was surprised to see how little clothing Silver had on underneath. While the pegasus wore an old hoodie and his regular jeans, it seemed that Silver was comfortable enough to only need a pink t-shirt and some gym shorts under his winter attire. Scootaroll was perplexed enough to stare at his mate in shock for a second, but Silver was growing too giddy about his coltfriend’s secret plan to really take notice.

“Okaaaayyyyy…” Silver Bell’s smile grew wider than Bubble Berry’s before a Cutecieniera, and he began to hop up and down while chanting, “Whatisitwhatisitwhatisitwhatisit?!”

“Alright, alright!” Scootaroll couldn’t help chuckling as he put his hooves out to settle Silver down. “If you want your present that badly, then I’ll tell you what it is. But first…”

Scootaroll grew a more sultry-looking smirk as he leaned in close, and eyed the unicorn before saying in a lustful growl, “The little Birthday Colt, needs to be back in his Birthday Suit~”

Silver Bell grinned even wider as he blushed deeply, and nodded in affirmation. While Scootaroll stood in wait with a more confident-looking smirk, Silver used his hooves to pull off the remaining clothing he had on. His t-shirt and shorts were soon tossed aside among the pile of their coats, which left the twinkish pony in nothing but his purple briefs. Of course, Silver wasn’t shy enough to stop there, and shivered giddily as he pulled down his underwear as well. By the time he was left standing completely naked in his living room, the only thing left on Silver’s body was the shiny, metallic chastity cage that was locked around his privates.

Scootaroll chuckled a little as he eyed his coltfriend with an amused grin, and took a second to admire that tiny cage between Silver’s legs. Silver Bell’s two-inch dicklet may have been measly enough to barely even be called a “cock,” but it was already beginning to twitch antsily inside of its thimble-sized confines. The unicorn didn’t say anything while he stood in the buff, but his blushed smile at his mate was enough proof that he wasn’t wanting him to stop. Fortunately, it seemed that Scootaroll was thinking the same thing as he pointed down at Silver’s cage, and made a surprising request. “You know what? I think you should remove your chastity cage too~”

Silver gasped in shock while staring at Scoot wide-eyed, but his horn lit up the instant he heard him say those words. “R-Really?!” he asked with a pleasantly surprised smile, and his pink tail wagging excitedly like a dog’s. Scoot noticed the tiny key float out from the bedroom by Silver’s magic, and watched as it flew directly down towards the birthday colt’s crotch. “Ohmigosh, thank you! I mean, I wouldn’t have been upset if you kept me locked up, but this is really thoughtful of you~”

Scoot chuckled under his breath, knowing that Silver likely said that one part in case his request was another fakeout. However, the pegasus waited silently until he heard a distinct metallic click, and saw Silver’s cage drop down to the floor. He then began to pull off his hoodie, and said while stripping, “Well… even though I’d love to keep that little nub locked up for good, I’m pretty sure that you won’t need it for what I have planned…”

Silver tilted his head in slight confusion, but still kept an antsy smile while watching his partner get naked as well. Scootaroll took his time as he pulled off each item of clothing he had on, making sure to keep Silver on edge while in that brief moment of freedom. Since the pegasus was bundled up in multiple layers, Silver already started to squirm needily before Scoot could take off his t-shirt. The unicorn’s petite, and currently unlocked cock sprung to life and tried to stand rigidly in wait. Unfortunately, even if Silver’s cock was freed from its cage for the first time in months, Silver groaned under his breath as he kept himself from touching the pathetically undersized nub.

Scoot made sure to shoot a teasing smirk at his mate as he stripped, knowing that he was purposely making him squirm from how long he was dragging it out. But despite how badly Silver groaned to himself while Scoot was flaunting around in his tented boxers, the birthday colt’s face lit up when that final garment fell down around his boyfriend’s ankles. Scootaroll’s thick, rigid stallionhood was already standing fully erect by the time he was completely nude, with the smooth orange shaft glistening from his built-up sweat. Even though almost any cock would’ve made Silver’s dicklet look miniscule in comparison, the sight of Scoot’s meaty appendage was intimidating enough to make the unicorn shudder with his hind-legs bunched together.

Meanwhile, Scootaroll waited until he was fully nude before he reached his muzzle into his pile of clothing. Silver Bell stood in wait as he tried to keep still, but his hooves were already growing jittery in anticipation. When Scoot finally got a good grip of the item he was hiding inside of his coat, he pulled his head back up to reveal a small glass vial sticking out of his mouth. Silver’s smile widened even more upon seeing that, and he immediately sat himself down after assuming what that bottle was for.

“Oooohhhh… You wanna give me an itsy-bitsy clit for my birthday?~” Silver asked with an antsy giggle before he spread his hind-legs wide apart, and shamelessly showed off his throbbing nub for Scoot’s amusement. “Hehehehe… Should I get my recording spell ready again?~”

Even though the unicorn’s excitement was cute enough to make him giggle, Scootaroll shook his head before he held the bottle more properly in his hoof. “Actually, ummm… this potion is a bit different from what we’ve done before.”

Silver’s ears perked up curiously, and he quickly got back up so he was standing again. “Oh, really?” he asked while wearing nothing but a piqued smirk. He tried to lean in and get a good glimpse of the vial, but there was no labeling to show what the bright blue substance actually was. However, Silver was able to see that Scootaroll’s present was indeed different from the cock-shrinking potions they usually used. “What is it then?”

“Well, ummm…” For a split second, Scootaroll was starting to second-guess whether or not this was a good idea. Even though Silver was already fully naked and eager for some fun, there was no way for Scoot to know whether or not he’d comply with this. Given how open and honest they’ve been with each other, he knew that giving Silver a gift he didn’t ask for was a huge gamble. And considering what this potion actually did, the looming fear of rejection was strong enough to make Scoot’s muzzle wrinkle in uncertainty.

“I, uhhhh… Wait a minute...” Scootaroll sighed as he made one last glance down at that bottle, and then looked back up at Silver to say in a sincere tone. “Silver, I… I just wanna say that if you don’t like this present, or if you think it’s a bit too much, I want you to be completely honest, alright? Because this potion is for, uhhhh… for something really specific, and… I know that it’s something you haven’t really mentioned to me directly…”

Silver Bell’s brows rose up while staring back at Scoot, and his expression started to look more bemused. Even though the pegasus was starting to sound wary, he breathed out before continuing to talk. “But, ummm… I’m hoping that you do like it, but… if you’re not a hundred percent on-board with the idea, do not hesitate to tell me, okay? I’ll completely understand if it’s too much, and I won’t be upset at all. I promise.”

Even though Scoot’s assurance to him sounded a little worrying, the sincerity in his tone was comforting enough to make Silver nod his head. “Well, ummm… alright then,” he said while giving a more reassuring smile to his mate. “If you’re really that worried about the potion, then… I promise I’ll be honest with you.”

He then leaned in and kissed Scootaroll on the cheek, which was just enough to make the pegasus blush with a more relaxed smile. “Ummm… O-Okay then,” he said with a slightly flustered voice, which went away the instant he breathed in more confidently. “Well, I… I got this potion made for you because, uhhhh… I… I couldn’t help catching a few of things you’ve said during sex the past few months…”

Silver’s head tilted a little, and his eyes narrowed on Scoot as he said, “Ummm… you might need to be more specific than that, hun~”

The unicorn’s cheeky smirk was enough to make Scootaroll chuckle lightly, and he nodded his head before replying, “Okay, ummm… Well, I… I remember what you’ve said about, uhhh… about… what you wished you could be for me?”

Silver Bell blinked his eyes a couple times in puzzlement, clearly needing a moment to think back to what he could’ve said. However, despite all the possibilities he could’ve guessed from the things he moaned out in bed, the wording of Scootaroll’s question made his eyes widen in an instant. “... Ummmm… Wait, you… You mean...”

Silver glanced back down at that bottle, and blinked a couple more times before he asked. “Wh… What’ll that potion do to me?”

Scootaroll was hopeful that his coltfriend’s wide-eyed stare was out of excitement instead of worry. However, since he had no idea whether or not Silver was aware of the potion’s abilities, the pegasus breathed out sharply before turning his muzzle away from him. “Well, ummm… It… It’s meant to, uhhh…”

Even though his face was practically burning with an embarrassed blush, Scoot tried to ignore his nervousness as he clenched his eyes shut and said, “The potion will, uhhh… it’ll transform whoever drinks it into… into whatever appendage is touching them…”

Silver’s eyes were growing as wide as dinner plates by that point, and his pupils grew outward while staring at that bottle. Despite how much the unicorn’s jaw was starting to gape open, he was able to ask in a more bewildered tone, “S-So… If… If I take that, and… a-and we have sex, then…”

Scootaroll was thankful that his boyfriend was able to make the connection himself, but the reveal still made him struggle not to cringe nervously. Nevertheless, even though it seemed that Silver guessed the outcome correctly, Scoot still opened his muzzle to clarify the potion’s use. “Ummm… Y-Yeah, if… if we have sex, then… then you’ll be transformed into my… dick.”

Silver Bell finally looked back up at his boyfriend, and looked absolutely stunned behind his wide-eyed gaze. “You… you actually got a potion to make me your cock?”

Scoot was worried he went too far, but he still nodded his head with great hesitance. “Ummm… Yes...”

Neither of the naked stallions said anything for a while after that response. While Scootaroll stood awkwardly before his mate with a reluctant pursing of his lips, he could only watch as Silver’s eyes looked between his face and that bottle. For a moment, the pegasus was certain that he finally found a limit that his coltfriend wasn’t willing to break. Even though he knew that it was bound to happen someday, the idea of doing it on his birthday felt unforgivable. After about twenty seconds of silence, Scoot closed his eyes with a pained sigh and began to speak. “Listen, I… I’m sorr--”

“GIVE IT TO ME.”

Silver Bell’s sudden response made Scoot jolt up a little in surprise. When he looked back at the unicorn, his eyes widened when he saw that Silver’s eyes were still wide-open in shock; however, the birthday colt also had an unbelievably wide smile of eagerness across his muzzle. He held out his hoof to Scoot, and repeated himself with an antsily determined tone. “YES. I WANT IT. NOW~”

Scootaroll blinked a couple times before he needed to jolt his head with a quick shake. Even though he doubted that would’ve changed what he just heard, he still appeared shocked from seeing how excited Silver Bell looked. “Uhhh… A-Are you sure you--”

Silver lit up his horn in an instant, and snatched the bottle from Scootaroll’s hoof before he could finish speaking. The unicorn then uncapped the bottle, and downed the whole thing like he was taking a shot at a bar. Scootaroll knew that he should’ve been happy his coltfriend liked his gift so much, but his muzzle was hanging open while one of his eyes twitched a little. “... uhhhh… Well, ummm…”

After Silver finished the potion with a quick and satisfied sigh, Scootaroll only needed another moment before he shrugged more calmly. “Okay then!” he said with a more natural-looking smile. “Uhhh, happy birthday, hun--OOMPH!!”

Silver Bell lunged forward to pounce his mate like a tiger, and threw Scootaroll onto his back in the middle of the living room floor. The pegasus wasn’t expecting his gift to elicit that strong of a reaction, but he couldn’t really complain when he saw how eager Silver was getting. The unicorn was blushing like mad with excitement as he grinded his waist against Scootaroll’s stomach, and started to kiss him repeatedly along the nape of his neck. “Nnnnghhh… Ohmigosh… S-Scoot, you… y-you have noooooo idea how many times I fantasized about that!!~”

Upon seeing just how antsy Silver Bell was acting after that reveal, Scootaroll couldn’t have felt more content about his decision. Not to mention, it was hard not to feel better about himself while feeling his boyfriend’s thick, plump cheeks grinding against his throbbing shaft. The pegasus hissed through his gritted teeth as he felt just how enamored Silver was getting, and tried to keep a cocky smile while staring up at him. “Heh heh heh… Well, it’s not like you were being subtle about it. I can distinctly remember a couple times while fucking you when you muttered about being jealous of my cock~”

Even though Silver was rightfully pent-up enough to shiver at that reminder, he still giggled a little before saying, “I… I kinda thought you… you’d just assume I was talking about your cock compared to mine~” Silver Bell then lunged down, and delivered a passionate kiss to his mate that lasted a good five seconds at least. As soon as he pulled away, and Scootaroll was left panting heavily from that surprising gesture, Silver was grinning wide as he added, “But, ohhhhhh~ Ohmigosh, Scoot… I’m soooooooo fucking glad you took that so literally~”

Scootaroll snickered as a more teasing grin spread across his face, and he took advantage of Silver’s position to grab both of those thick flanks with his hooves. Silver groaned girlishly as he squirmed from the stallion’s tight grip, and felt each throb of that meaty cock pressing between his cheeks. Even though he had fantasized about taking the place of Scoot’s stallionhood for a long time, the idea of actually making that wish come true was leaving him more excited with each passing second. Of course, it seemed that Scootaroll was devilish enough to test just how badly Silver wanted that fantasy realized.

“Mnnnghhh… You must be reeeeaaaallllly desperate to take my cock’s place, don’cha?~” he asked in a teasingly sly tone as his smirk widened. While Silver Bell moaned out direly and tried to keep his muzzle shut, his body writhed strongly when he felt Scoot’s current cock rubbing against his backside even harder. “Is your little nub really that pathetic, babe?~ Is that puny thing really so tiny and useless, that you’d rather be a cock yourself to make up for it?~”

Silver’s enamored lust may have been greatly intensified after his months of chastity, but Scoot’s taunting words were riling the unicorn up like nothing he could’ve imagined before. His measly little dicklet was already beginning to spurt out little droplets of pre as it continuously throbbed to the thought of such a transformation, but the tiny strings were insignificant enough for Scoot to even acknowledge. Instead, the pegasus kept his grin pointed up at his twinkish bitch while hearing him moan out, “Aaaahhhh!!~ Nnnffff… Oh, Gods yes!!~ I… I wanna be your cock, Scoot! I wa… I wanna be… I wanna be the cock I always wanted!!~”

Silver Bell’s needy pleas were satisfying enough to make Scootaroll snicker in delight, but he continued to grind against that pudgy ass as he kept teasing him. “Mmmmm… How badly you wanna be my new cock, huh?~ The potion won’t take effect for a few more minutes, so you better make it clear…”

Secretly, Scootaroll knew from Buck that the potion wouldn’t really take effect until the two began to have sex. However, that little fib provided just enough incentive to really make the unicorn squirm in dire need. “AAAAHHH!!~ P… P-Please, Scootaroll!!” He began to grind his ass against Scoot’s cock with greater force, which caused the pegasus to hiss while hearing him shout, “Please, let me be your cock!! I… I-I’ll beg for it if I have to!! Aaaahhhh~ I… I clopped to the thought s-s-oooooo many times, and I… I can’t take it anymore! Turn me into your cock, Scoot! I’M BEGGING YOU, PLEEEEAAASSSSEEEE~”

“Nnnnnnghhhhh~” After Scootaroll’s hips writhed upward with an especially antsy groan, he shivered in satisfaction before smirking cheekily up at his mate. “Oh, alright then~” he said with a cocky tone of voice. “How about you give it a little taste first? Get it niiiiiiice and wet~”

Silver Bell let out a brief moan while nodding his head fervently, and pulled himself off the stallion so he could bring his head down between Scoot’s hind-legs. He shivered with a heavy groan upon seeing that well-endowed stallionhood up-close, and didn’t hesitate to give a heavy lap of his tongue up the pony’s rigid shaft. Scootaroll sighed blissfully as he leaned his head back, and moaned in pleasure the instant he felt Silver’s lips wrapping tightly around his cockhead. “Mmmm… that’s right, you little clit-dick bitch… G… Get yourself acquainted to your new home~”

Silver Bell shuddered antsily to that remark, but didn’t falter on his fellatio as he continued to suckle on that plump cockhead. Despite how much he loved worshipping Scootaroll’s cock whenever he was told to, the idea of actually being that very cock would’ve been enough to make him cum right there and then. Fortunately, the unicorn was able to keep his focus as he closed his eyes, and savored the musky taste of Scootaroll’s sweat while slathering his tongue all over that rigid member. His ears twitched readily each time one of his motions made Scoot moan out in pleasure, and his fur stood up on end when he heard him say, “Aaahhh! You… You should be lucky you get to be a real cock for a change~ G-Given what you have, this… this is probably the closest you’ll ever get to having a proper dick like mine~”

That comment may have been meant to insult and humiliate the unicorn, but Silver Bell just let out a muffled moan of contentment while trying to shove more of that meaty length into his muzzle. His lips were drooling with each slide they made up and down Scoot’s shaft, which helped to slather every inch with a thick sheen of Silver’s saliva. By the time he finally pulled his mouth away with a wet pop, Silver was pleased to see how badly Scoot’s cock was twitching after that tantalizing oral. He may have not gotten his mate off from it, but both of them knew that wasn’t the purpose. All that Silver needed to do was get it wet, before having the chance to take its place~

“Aaaahhh~” Silver Bell instantly crawled up on top of Scootaroll’s body, and perched himself right above that waiting cock while his hole was puckering needily. The unicorn may have thought there was a time-limit for that potion to start activating, but both of them were growing eager to see the results by the time he lowered himself down.

Scoot groaned with a curious grin as he watched his coltfriend get in position from above, and waited until his tailhole was just inches away from that waiting head to say, “Thaaaaaat’s right, you little slut… let’s see how well you can take my cock’s place~”

Silver Bell grinned with an eager nod of his head, and lowered himself down while he blushed profusely. The pony moaned out as soon as he felt that meaty head, and had to close his eyes to relax himself. Fortunately, due to the unicorn’s immense experience bottoming for Scoot (not to mention his added weight and lubrication), the initial penetration wasn’t nearly as tedious as one would expect. Silver Bell only needed a minute or so as he groaned hard from that familiar pressure, and eventually sighed when he felt his tailhole stretch around his mate’s girth. Due to his chastity cage being undone, the stallion couldn’t hold back his lustful moans as he pushed himself down Scoot’s shaft, and felt his own little nub twitching from each throb it made. By the time the little twink managed to slide himself down half of that thick shaft, his body began to convulse more rapidly from his unrestricted arousal.

“Nnnnghhhh~” Scootaroll clenched his eyes shut as he groaned especially hard to Silver’s tenacious pushing, and felt that tight little hole gripping his length like a vice. He knew from Apple Buck that the potion would only activate when Scoot’s precum was inside of his coltfriend, which was why he had to get that semen sample the previous week. Even though there was a chance Silver could’ve activated it during his cocksucking, the pegasus was fortunate that his mate went for the main event so quickly. He could feel how badly his cock was throbbing inside of Silver Bell, and gritted his teeth upon feeling inch after inch of his shaft being swallowed up by that hungry hole. He had no idea when exactly he began to leak precum, but he could feel his nethers tingling intensely around the same time Silver Bell’s moans grew more dire.

“AAAHHHH!! Ohmigosh!!~” Silver felt a jolting shock from deep within his backside, and his entire body convulsed sharply the instant he felt several distinct throbs of Scootaroll’s cock. His mouth hung open as he reeled his head back, and let his body weight slide the final couple inches of Scoot’s cock inside so he would be balls-deep. The familiar fullness was satisfying enough to make his own nub continue to spurt out pathetic drops of precum, but it was that alien-like tingling within him that was causing his dicklet to throb harder than ever before. His hooves were curling in from the titillation that was spreading out from inside his bowels, and causing every nerve in his body to stand on end from the growing intensity.

“MNNNNGHHH!!!~” Silver Bell could recall several times where Scootaroll threw him to near-nirvanic levels of pleasure, and left his body tingling bad enough to barely get out of bed. But as soon as he felt that first hefty spurt of pre shoot inside of him, he could instantly tell the potion was taking effect from how intensely sensitive his nerves began to feel. His white fur was sticking out like a petrified housecat, and he couldn’t stop quivering as he felt his hooves shaking involuntarily. With each spellbindingly long second that passed, Silver could feel his body turning more sensitive to the slightest touch. Even the movement of his hooves against the carpet left his mouth hung open to moan out in pure rapture, like he was being thrown to the deepest abyss of tantalizing bliss.

Scootaroll was feeling more sensitive as well, but that titillation seemed to remain purely around his cock and nowhere else. Nevertheless, the pegasus was still left groaning from the pleasurable throbs that shot up and down his shaft, and reverberated across his thighs. His hind-legs were squirming from the intensity that was wrapping itself tighter and tighter around his cock, but Scoot maintained his composure enough to keep from letting those feelings stop. Instead, the stallion could only look up at his mate with his eyes half-lidded, and bite his lip upon seeing how well the birthday colt was handling that potion.

Without thinking, Silver clutched his chest with both forelegs crossed over one-another, like he was laying down inside of a coffin. Scootaroll flinched from how sharply the unicorn shrieked out from that motion, which seemed to have pushed the limits of his over-sensitive nerves. His hips tried to thrust forward a couple times, but it appeared as if he was firmly planted against Scootaroll’s waist as he succumbed to a very overwhelming orgasm. Scoot let out a hefty gasp as he felt Silver’s body clenching hard around his cock, and causing his hips to writhe from the sudden intensity that wouldn’t let up; meanwhile, Silver Bell cried out in pure, unadulterated rapture as his little nub twitched like mad, and shot out multiple strings of his cum. The orgasm itself wasn’t anything special, since those measly loads barely amounted to a thimble’s worth of his seed; however, the fact that a couple of those strings landed past Scootaroll’s chest proved just how much that simple movement set him off.

“Nnnnghhhh~” Scootaroll wanted to say something positive about that somewhat-impressive cumshot, but he decided to just add more fuel to the fire instead. He brought his hooves up to grip Silver’s sides, and elicited another blissful shriek as the unicorn spasmed even harder atop his waist. “Heh~ You call that a cumshot?~” he jeered mockingly. “Nnnnngggg… Man, I can’t wait to give you a proper load that shoots out of your mouth~”

“MMMMPH!!~” While the twinkish pony trembled and panted rapidly, only a couple more measly drops of cum were able to dribble out of his dicklet while Scootaroll stroked the sides of his torso. The sensation was beyond invigorating to Silver, who couldn’t stop moaning mindlessly from each titillating movement those hooves made to set his nerves ablaze. However, it seemed that Silver wasn’t the only pony moaning from those strokes; Scootaroll clenched his eyes shut as he continued to rub his coltfriend’s sides, and began to feel an unfamiliar tingling that extended beyond his waist…

Holy shit! Thought Scoot to himself as he tried to keep his lustful groans from growing too audible. I… I can feel it! I can… I can feel his nerves tingling like they’re mine!~

“AAAHHHH!!” Silver Bell’s head shot back with an especially sharp spasm, and his body began to freeze in place while he was being rubbed by Scootaroll’s hooves. His eyes closed tightly as those intensifying strokes left him immobile, and kept him from seeing just how significantly that potion was taking effect. Fortunately, Scootaroll was able to see the progression the instant he opened his eyes, and gasped shakily to the sight occurring above him. He had no idea how Silver was taking it as his appearance began to alter, but Scoot’s eyes refused to even blink as he gawked up at his boyfriend in utter awe.

At first, Scoot thought his eyes were playing tricks with him, as he could’ve sworn Silver’s mane was becoming shorter. However, it turned out that the unicorn’s hair was starting to deplete back into his scalp, like some freakish reversal of a mane-growing potion. Meanwhile behind Silver’s writhing hips, his tail was flicking less intensely as that began to revert inward as well. By the time his curly pink and lavender hair began to disappear completely from sight, the bare dock of his tail was still wiggling like mad while he moaned from his overwhelming pleasure. Of course, from the angle Scootaroll was lying, that shrinking tail was nothing compared to seeing Silver Bell’s horn start to sink away into his forehead.

“Ho… Holy fuck,” Scoot muttered before growing a very satisfied grin. As he continued to rub Silver’s body up and down, his hips thrusted upward to really make use of Silver’s changing body. “Mmmmmm… You’re… You’re starting to lose all your hair, dick-boy~ Soon… Soon you’ll start looking like a shaft~”

Silver tried his hardest to thrust himself against Scoot’s waist, but it was obvious by that point that he wouldn’t have been able to. With each stroking motion Scoot made with his hooves, he began to moan louder as he felt that body becoming more at-one with his previous stallionhood. All the while, his eyes struggled to stay open as he saw Silver’s horn slowly disappear from view, and sink beneath his fur to leave him unable to escape. Although, given how badly the pony was moaning from his invigorating transformation, it was doubtful that he would want to escape anytime soon.

“Aaaaahhhhh… You like that, Silver?~” taunted Scootaroll with a cockier-looking sneer as he grew more enticed with Silver’s transformation. “Oh, man… I can’t wait to see you take the shape of my cock next~ May… Maybe you’ll prove yourself to be useful for a change~”

Silver’s moans lingered on as his fur began to disappear next, and Scootaroll saw those white hairs sinking back into his skin in nerve-inducing waves. By the time the pony was left completely hairless and hornless, the real transformation began to occur as Silver’s neck started to swell outward. The top of his shiny head slowly bulged out as well, forming a uniquely crowned ridge around the sides while the top of his muzzle remained familiarly flat. And between Silver’s fidgeting legs, which were beginning to diminish in size ever-so-slowly, that tiny nub of a cock and balls sunk back into what used to be his waist before disappearing completely from sight.

“Heh~ Took that useless thing long enough,” teased the pegasus mockingly. He then shouted out between his enticed groans, “Nnnnghhh… You hear that, Silver?~ Your dick’s gone for real! Now, the… the only cock I can see is you~”

Silver’s moans started to diminish in intensity, and became weaker with each breath he made through his still-open muzzle. Scootaroll couldn’t get a great look at his mate’s face from where he was, but he could tell that his mouth was still open as it distorted its way upward within that crown. The stallion’s spasming hooves retracted back to the sides of his hairless torso, and flailed about wildly with each inch that sunk away from sight. While the pony’s body continued to morph and alter itself for both of their nerve-tingling pleasures, Silver Bell’s torso was left convulsing as his figure began to shrink, and a thick ring-shaped bulge began to grow out between what used to be his chest and stomach.

“Th-There’s the medial ridge!” Scoot shouted pridefully as he kept thrusting Silver between his hooves, and the former-unicorn’s moans slowly died off completely. “You… You’re almost finished, you big, throbbing cock! How does that feel?~”

Silver Bell tried to shout out in absolute glee, but he couldn’t feel his vocal cords the more his face contorted without pause. His mouth was thankfully still open, but even that began to morph into something more akin to a thick slit. The pony’s nose disappeared from sight atop that flattened head, and his still-clenching eyes contorted their way past his mouth to move towards the top of that swelling cockhead. Just as Silver’s hooves began to disappear completely inside of his now-smooth torso, the only thing that he could let come out of his “mouth” was an unexpected glob of Scootaroll’s precum.

“Nnnnnghhhh!!” Scoot stopped his thrusting, and started to take advantage of that freshly-formed shaft as he stroked Silver’s body even more. He grinned like a madpony as he saw Silver’s head pulsating with each throb, and another hefty dollop of pre oozed out from that horsecock-slit that used to be his mouth. He could tell that Silver was still somewhat-conscious, since his strengthening body was still wriggling uncontrollably in its rigid and throbbing state. Of course, given how hard his glistening head was pulsating, and drooling copious amounts of Scootaroll’s pre that began to dribble down his shaft, it was doubtful that Silver could really process what was happening in his erect form. Nonetheless, the pegasus still shivered with a cocky grin as he called up to him mockingly, “I… I hope you like that potion, Silver Cock! Because this is the closest you’ll ever get to being hung!~”

Scootaroll then groaned even harder as he clenched his eyes shut, and placed his focus on actually masturbating with his new living cock of a boyfriend. He couldn’t hear Silver’s girlish moans anymore, but he could tell he was still beyond pent-up as he continued to throb and twitch as Scoot’s new appendage. While his slit-mouth kept coughing up gooey rivulets of precum, he didn’t seem to notice as his shaft shrank to a more cock-sized proportion. By the time the shrinkage finally stopped, there was no doubt that Silver had been turned into a fully-functional, and well-endowed stallionhood for his mate. The overall size was slightly larger than what Scootaroll originally had, but that smooth shaft carried the same color as Silver Bell’s original coat. And as more drops of Scoot’s pre traveled down that throbbing shaft, they trickled across the pegasus’ still-orange and enlarged balls; surprisingly enough though, it seemed that Silver Bell’s cutie marks haven’t disappeared like the rest of his features, and have instead settled across the sides of his coltfriend’s churning balls.

Meanwhile, as the final features of his new form settled atop Scootaroll’s crotch, Silver Bell could still breathe through his “mouth” between the constant spurts of his lover’s pre. But other than that, as well as the occasional blinks he was able to make with his near unnoticeable “eyes,” Silver could barely make any movements of his own while he was trapped in such an inanimate state. However, it was doubtful that Silver saw that as a negative trait when his entire body was tingling endlessly from his boyfriend’s strokes. Each diligent movement felt just as intense and mesmerizing as the first time Silver Bell learned to masturbate with his hoof; except this time, that electrifying tingling that set him on edge was coursing throughout his entire body, and left him in a state of euphoria that words couldn’t even begin to describe.

“Aaaahhh!!~” Scootaroll’s limbs were beginning to tense up as he jerked his new cock as vigorously as a teenager left alone in his bedroom. His mouth hung open while he panted rapidly from the physical strain, but he couldn’t stop looking down at that throbbing Silver cock while grinning in anticipation. “I… I’m just about to shoot, Cock-Boy! Mnnnghh… I… I hope you’re ready for this!!~”

Silver Bell may have not been able to speak, but his constant throbbing between Scoot’s hooves made it clear enough that he was more than ready. The stallion-turned-stallionhood could barely think while his new body was being thrown into such a wonderfully lustful high, and his glistening cockhead was now coated in his lover’s precum. After all the countless nights he spent fantasizing about this moment, Silver would’ve never predicted that the actual thing would feel so much more amazing. His fraying nerves were leaving him in a deep cloud of arousal as he felt his throbs churning harder, and Scoot’s balls riding upward with each glob of pre he coughed up. He had only been Scootaroll’s penis for a few minutes at most, but Silver was already experiencing enough pleasure to never want it to stop.

Of course, as soon as he heard Scootaroll let out a deep and strained moan from behind his cockhead, Silver Bell couldn’t have felt more elated when he finally came.

“GNNNAAAAAAHHHH!!!~” Scoot’s hips jerked up several times, and he cried out in utter bliss as he succumbed to the pleasures he and Silver were able to share so deeply. Silver Bell froze like he was hit by a cockatrice, and tried to spasm wildly as he felt a heavy bout of warmth churning from deep below him. That skin-tingling sensation shot up through his shaft of a body like a rocket, and caused an instant upchuck from Silver’s slit to shoot out a massive volley of Scootaroll’s cum. Silver may have been able to somehow see, but his eyes still rolled back as he throbbed and spat continuously between Scoot’s jerking hooves. He could feel each hard churning of his mate’s balls underneath him, and didn’t even try to stop him from spurting out each heavy rope. The entire session felt so unbelievably strong and mind-bending, but all that Silver could truly process was how amazingly his dream was realized.

He just shot a load as Scootaroll’s actual, functioning cock. And he absolutely loved it~

“AaaaaAAAAAaaaahhhh… Mnnnnnnfffff…~” Scootaroll needed to lay back after that uniquely titillating session, and let out a heavy sigh of post-orgasmic pleasure. Silver Bell was left untouched as he felt himself slowly leaning forward in a semi-flaccid state. His cockhead was still thoroughly glazed in his lover’s cum, but it was hard to care when his shaft was still tingling from the aftershocks of that perfect climax. If he were able to speak, Silver would’ve been thanking Scootaroll profusely for giving him such a new and wonderful perspective to receive stimulation from. But even if he was left mute and near-inanimate, the pegasus’ new cock wouldn’t have wanted to change how he was in any way.

“Y… You feeling alright, little guy?~” Scoot asked with a weak gaze down at his new cock, hopeful that Silver could respond in some sort of way. Luckily for him, Silver used whatever strength he had to try and move his body, which elicited a strong twitch of his shaft that his mate was able to see. Scootaroll smiled with a thankful nod, and then said, “Alright, good. I know that Apple Buck said he put a few failsafes on that potion to keep you safe, but I wanted to make sure just in case…”

The pegasus needed another moment to compose himself before he got back to a seated position. By the time Scoot was feeling more refreshed, Silver was left completely flaccid while dangling sloppily from the stallion’s crotch. He was undoubtedly tired like a dog, but wasn’t able to sleep while connected to the still conscious pony. Instead, he could only lay in an immobile state as he heard Scootaroll speak more casually. “Okay, ummm… Just so you know, this potion is supposed to last Twenty-Four hours, so I promise you’ll be back to normal by this time tomorrow. Understood?”

Silver managed to make another measly twitch in his new form, which Scootaroll saw as a sign of affirmation. He then decided to add, “Also, Apple Buck made sure the potion had a telepathic element as well. It’s not much, but it can give you the ability to communicate a little. You can be able to send signals to indicate if you’re okay with doing something, kinda like that whole ‘Red Light, Green Light’ thing. I’m not entirely sure how it works, but he said you could figure it out pretty easily.”

Silver Bell wasn’t exactly sure what that meant either, but he was grateful he was able to think while taking the place of Scootaroll’s cock. Since he wasn’t erect anymore, he was able to process his thoughts more coherently than before. So after he closed his “eyes,” Silver tried his hardest to focus on that ‘Red Light, Green Light’ idea; and after a few seconds of silence, all he could think to do was think of a stop light giving a green signal. Much to his and Scoot’s surprise, his thought was able to elicit a strong shudder that crept throughout the pegasus’ hind-legs.

“MMMMPH!!~ Y-Yeah, like that!~” Scoot smiled more naturally while chuckling to himself, thankful that Apple Buck was that skilled of a potionmancer. Even though he wasn’t entirely sure how well Silver was processing everything following that orgasm, Scoot smiled optimistically as he asked down at him, “So… are you alright with staying like this for the rest of the day?~”

Silver Bell couldn’t have responded quicker, and thought of a huge green signal that made Scootaroll shiver intensely. “Nnnnnghhh... Alright, good to know~”

When he finally pulled himself up from the floor, his chest and stomach were drizzled in multiple ropes of his cum that clung to his orange fur. He only needed a quick wipe with his towel to feel clean again, but made sure to walk slowly as he trekked to the bathroom. Silver dangled helplessly between Scoot’s legs with each step, and shivered in delight as he felt himself moving just as a stallionhood should. Scootaroll was quick to clean off his stickied fur, but shuddered with a wider grin when wiped his new cock with more thought. Silver could’ve moaned as he felt that soft fabric rubbing against every inch of his sensitive skin, but couldn’t do anything to physically show his enjoyment while he hung like a piece of meat.

After he was finished, Scootaroll walked back into the living room to retrieve his clothes. Silver Bell had no idea what his lover was planning to do, or just what the pegasus had planned for the remainder of his birthday. However, the instant he saw those boxers being pulled up Scoot’s legs, Silver couldn’t contain his curious excitement as his vision became blocked by the tight fabric. Fortunately, he was still able to hear Scoot as he said, “Heh~ Just so you know, I still have a lot of errands to do today, so you’re gonna have to stay right there throughout everything~”

Silver Bell knew that this sort of experience would leave him completely at Scootaroll’s whim, but hearing how casually his coltfriend was treating him in such a demeaning way was making him twitch in arousal again. But alas, his body as a whole remained soft while he was trapped against his boyfriend’s musky crotch, and heard him add, “You need to say anything before I go Cock-Boy? Oh wait, you can’t~ Heh heh heh…”

Silver then felt the pegasus put on his pants, which further encased him within a heavy veil of darkness. He knew he should’ve been worried about what might happen next, but it was hard to feel too nervous when the sensation of his encasement felt so good. So instead, all Silver Bell could do was think happy thoughts, and appreciate his new role as Scootaroll’s cock as he went out on the town...
