Two ponies sat down for lunch at the cafe in Ponyville, chatting with each other over the recent scandals revealed in the local school's newspaper, the Foal Free Press. A pegasus and an earth pony, they had been together for several months, but a revelation about the pegasus started a lot of rumors about him in the town. However, the two did not let this deter them from meeting for lunch the next day. As the pegasus began to nibble on the daisy and peanut butter sandwich he had ordered, his coltfriend watched him. The earth pony, a yellow geologist by the name of Quartz Poker, carefully gauged his mate's reaction as he mulled over which of the details in the scandalous article to ask about.
“So you really had a nursery built?” Quartz asked between sips of his water.
Steel Tempest, a grey pegasus and member of the Royal Guard, blinked at the question as he processed what was being asked. His ears splayed a little as he looked around nervously. “Shh!” He turned back to his companion, leaning in conspiratorially. “I, uh…yes.”
Quartz’s eyes twinkled, and he nudged Steel playfully. “So that Foal Free Press thing was right, huh? You’re a pretend-foal?”
There was a moment of silence. Steel took a bite from his sandwich, chewing the bite and his response over methodically. He swallowed and turned back to the yellow earthpony, shaking his head. “Well that’s a fine question to ask on a date.” Quartz grinned apologetically, so Steel continued. “No, no…I’m going to be taking care of a colt soon, though. That’s why I had that nursery built.” He took another bite. “I don’t really want to talk about it right now though. Its, uh, personal.” Steel continued to munch on his sandwich, the conversation dying as minutes passed. The earth pony began to get impatient and fidgety- Half an hour and his order of hay fries still wasn’t done.
“Hey Steel, I’m gonna go see what’s keeping them.” Quartz nosed the pegasus softly and got up, smirking a little. “Don’t talk to any strangers now, we don’t want you foalnapped.” Steel groaned a little. Whoever that Gabby Gums pony was, they had come this close to ruining his plans, and he did not appreciate that. However, there was an interesting note of humor in the earth pony’s teases, and Steel smirked. He watched Quartz head inside before rummaging through his saddlebag and extracting a small blue bottle. Uncorking it with a pop, Steel poured the potion into Quartz's drink with a barely-concealed grin- the nursery was for a very special colt, after all, even if they didn't know they were a colt yet.
Steel and Quartz were strolling up a street as the sun began to set. They had been to a wood-shop to see about getting a crib, a foal’s clothing store for several sets of clothing and pajamas for the colt, and a specialty carving store to retrieve a special package that Steel had ordered. All these were passed off to Quartz as preparation for the colt’s arrival the next day, and the earth pony accepted the explanation without question. After these stops, the two had opted to visit the park at Quartz’s insistence. The earth pony had tired himself out running around in the park and was now half-leaning on the pegasus as they walked to Steel’s house. Quartz shivered a little as the temperature dropped, pressing himself closer to the larger pony, and Steel draped a wing across Quartz’s back in response.
Minutes passed in silence, the two just trying to beat the cold as they navigated across a grid of streets and train tracks to Steel’s home. After a while, Steel decided to speak up, and he nosed Quartz to get the earth pony’s attention.
“So what was all that about? You almost set a new land-speed record back at the park.”
Quartz blinked a little, returning Steel’s gaze before grinning sheepishly. “I dunno, it just seemed like fun.” He paused a moment. “Shame about that slide, though.”
Steel stifled a laugh, remembering Quartz attempting to fit down a tube slide just slightly too small for a stallion. “Yeah, they don’t make those for ponies as big as you, do they? And you accuse me of being the pretend-foal.”
“Well it looked like fun! Why can’t big ponies go on slides?” Quartz nosed against Steel, who smiled warmly in response. The pegasus noted privately to himself that the potion appeared to be working- Quartz was normally not very energetic and certainly never would cuddle up in public normally. However, the earth pony was now acting more and more like a colt as the hours went on, and Steel couldn't be happier. Quartz, however, merely yawned and gave the pegasus a soft headbutt.
“Hey, can I sleep at your place tonight? I can help move the colt’s stuff in tomorrow if you’d like.”
Steel grinned. Part two of his plan was about to begin. “Sure! I’d love that.” The two ponies continued walking in silence, soon approaching Steel’s house. As they entered, Quartz yawned again and clambered onto the couch in Steel’s living room, claiming it for the night. Steel giggled a little, knocking the door closed with a rear hoof before grabbing a cord with his mouth and tugging, pulling the curtains of the living room windows closed. He wanted some privacy for what was about to happen, and didn't need any nosy newspaper ponies spying on them.
Quartz had settled in on the couch, tucking himself against the arm and back of the sofa and drawing his forelegs up to his chest, ready to sleep. However, instead of getting the lights, Steel quickly hopped onto the couch, standing over the earth pony and smirking.
“Hey, don’t go to sleep yet Quartz, we still have something to do.” He reared up a little before the earth pony could protest, revealing his swelling sheathe and sac to his guest. Quartz had opened his mouth to say something but quickly fumbled over his words, suddenly unable to remember what he was gonna say as his eyes locked on Steel’s sheathe. The tip of the pegasus’ stallionhood was beginning to emerge, the dark flat head contrasting invitingly against his gray coat, and Quartz’s head automatically moved forwards as he shifted his body position by turning on the couch, half on his side as his forelegs were drawn underneath him, supporting his upper body. Quartz slowly sniffed at the air around the sheathe, his tongue running over his lips involuntarily as his eyes glazed over. A hoof reached under his chin, causing his eyes to flick up and meet the gaze of the pegasus while his snout was just inches away from the tantalizing flare of the stallion above him-
“See something you like down there, Quartz?”
Quartz blushed, his ears splaying. He nodded a little. “MMhmmm, I d-do…” He was surprised to feel something bump against his snout, and gave an eep of joy and surprise when he found that Steel’s cock had closed the small gap that separated it from Quartz.
“Do you want it?”
Quartz’s mind was fuzzy, the words reverberating around as his tongue barely flicked across the surface of the cockflesh. His stomach rumbled with hunger, and a strange thought occurred to him: It was time to feed. “Uh-huh, I-I wanna suck on i-it.”
Steel grinned, knocking the earth pony’s hat off before pressing his tip to the pony’s needy mouth. Precum coated the earth pony’s snout and lips as he tried to kiss at the tip, his tongue snaking out to lap at it between kisses. Steel pulled back a little every time, teasing Quartz just a little more as he ran a hoof across the earth pony’s flank, admiring a cutie mark that would soon change…He ruffled Quartz’s mane with a forehoof. “Then do it.”
Quartz needed no more encouragement, wrapping his lips around the tip immediately and suckling on it, his eyes closing as he established a regular rhythm. This was bliss to him- Steel’s warmth and weight above him, the pegasus’ shaft in his mouth, precum flowing into his belly- it was all perfect for the earth pony, and all the strange events from the day faded from his mind. This was where he wanted to be, suckling hungrily on his lover’s shaft.
“So Quartz- mmmmm, that’s a good boy…I never told you about the colt, did I?” Steel’s wings flared a little as he thrust forward, burying a little more of his shaft in the eager mouth of the earth pony. “ I think you’d like him if you ever got to meet him. He’s just the cutest little earth pony…curious, loves rocks, loves to explore…And the silliest thing, here he is getting his bedtime snack.” Steel let the words hang for a moment- Quartz was still thoroughly enthralled with his shaft. Perfect. “You’re gonna be my colt, Quartzy, and you’re nursing just like a good colt should.”
There was a brief moment of protest in the earth pony’s mind. His mind fumbled over the events of the day, trying to figure out if he had misheard or if Steel was just teasing him. He opened his mouth a little, thoroughly intent on pulling off and asking what Steel meant-
-And plunged his head forward, taking more of that wondrous cock into his maw. What did it matter if Steel was teasing him? He was loving every second of this so far, why should he let a little teasing play bother him? Curiosity filled him, and images of being pampered like a little colt filled his mind. It might even be fun, Quartz decided, as long as he could suckle more on this glorious shaft.
Steel beamed in triumph, his tail swishing as the earth pony took his shaft even deeper. His plan was working, and now he could openly tell his mate all about it- Quartz wouldn’t mind now that he was fully under the spell. He ran a hoof through the earth pony’s mane, applying the slightest of pressure to guide that hungry maw further and further onto his cock. “Yeeeeessss, that’s a good colt…you love nursing my cock, you love your daddy’s juices, don’cha? You’re gonna get this every day…” The earthpony actually seemed excited by that- looking down, Steel could see that Quartz’s shaft was half-erect, flopped onto the couch and leaking precum generously. Steel grinned again, feeling the rhythmic suckling on his shaft approach a more insistent nursing pattern, a new mindset with plenty of experience taking hold in his soon-to-be colt. “You’re gonna be my little cock-cuddling colt, aren’t ya?”
Quartz’s mind was doing somersaults as bits and pieces of it went fuzzy before returning a little different. His pace had picked up, his mouth on autopilot as the brainwashing filled his mind with experience and skill like he had been giving blowjobs his whole life. Minutes passed, though it could have been hours or even days and he wouldn’t have noticed. His world was the shaft in his maw, the pony above him, and the words in his ears that rang truer and truer with every second. His eyes closed and he gave a soft cry around the shaft, unable to focus on anything else.
The changes occurring in the earth pony’s mind were making him better and better at sucking cock, and soon Steel’s shaft began to burn with the tingles of a rising orgasm. He moaned a little, trying to maintain a dominant composure as his wings beat against the air in an exercise of excitement. He could submit and cry out to the masterful maw of his colt later- For now, he needed to make sure the imprinting took hold in his earth pony. The stallion’s shifting mind was malleable only as long as a cock was in his maw and the right words were being said, planting the right ideas in Quartz’s mind. Steel had to remain dominant if he wanted to be a daddy. “Oh such a-a eager little colt. Y-you’re about to get a reward, s-so open up for Daddy…” He felt the maw around his shaft oblige, opening a little in anticipation, and with a grunt Steel thrust forward again, the tip of his shaft in the back of Quartz’s throat as jets of cum erupted down the colt-minded-stallion’s gullet.
Quartz swallowed every bit of cum hungrily. The very last sentence rang through the fog of the pony’s mind, settling and cementing the trance he was in. His daddy had given him a reward! With that, Quartz was no longer a stallion with a pegasus lover: instead, he was the luckiest little colt in the world, happily suckling his father’s shaft for his bedtime snack. He gave a soft squeak of joy around the shaft, his maw tightening around it as he began suckling again, burbling happily to himself around the length.
Steel basked in the pleasure of his orgasm and the renewed suckling of his colt, tilting his head back and moaning softly as he traced a hoof over the earth pony’s shaft. There was still much to do, but plenty of time to do it. By the time Celestia had raised the sun the next morning, Quartz the geology pony would be Quartzy the cock-obsessed colt. If Quartz had felt the touch on his shaft through the settling remains of his mind, he didn’t show it, and Steel grinned. “You’re such a good little cocksucker, Quartzy. Suckling like a good little slut, just like Daddy wants. Get me to cum again and you can stay up late with Daddy.”
Quartzy obliged his daddy, suckling intently on his father’s shaft. His mind was still in disarray, the old parts that made up the adult Quartz still putting up little bits of resistance even as they were shepherded by arcane energies away from the colt-minded-stallion’s centers of thought. Old memories and ideas and notions were becoming irrelevant to pleasing Daddy, but they were still dangerous until the magic had set. It wouldn’t be long until the magic was finished, though- Another load of cum and they would be locked away forever.
Soon enough, the rhythm of Quartzy’s needy mouth had washed away the sense of time for either pony, and Steel once found himself moaning out as his shaft twitched in the colt-minded-stallion’s throat, flooding the earth pony’s stomach and setting the magic in place. Quartzy squeaked in glee around the shaft as his mind cleared, the old Quartz forever locked away in the back of the colt’s mind. Soon, Steel began to withdraw his shaft from the mouth of the colt-minded-stallion, causing Quartzy to whine out in protest.
Steel snickered to himself, his shaft dripping with cum and saliva. Quartzy had really gotten into the blowjob, it seems. “Now now, don’t be sad…you can still lick it clean.” No sooner than he had finished talking, Quartzy’s muzzle was pressed up against the shaft, tongue gliding over it in wide swipes. It was quickly cleaned off, and Steel flapped his wings a little, hopping into the air and quickly settling back down on top of Quartzy, who cooed. He cuddled his colt there on the couch as their erections retreated, though Steel noted that Quartzy’s sheathe was still rather full even as his shaft retreated from view. The pegasus quickly began plotting out his next move; he could just leave Quartz like this, maybe let it wear off on its own eventually…or he could take it further.
“You did a very good job there, Quartzy.” Steel nosed the earth pony, who wiggled a little against him, full of energy and affection. Steel chuckled, sitting upright on the couch and pulling the squirmy colt-minded-stallion to him. “So how much does Quartzy love his daddy?”
Quartzy placed a hoof to his mouth, thinking for a moment. He then smiled widely, spreading his forehooves wide. “This much!” He giggled and snuggled up against the pegasus, cooing. “I love you that much, daddy.”
“Awwww…I love you that much too.” Steel wrapped his colt in a full-body hug, wings and forehooves pulling the earth pony to him. They exchanged nuzzles, the younger-minded of the two constantly giggling. Eventually Steel reached his decision, and he pulled away to look the earth pony in the eyes.
“So Quartzy, ya thirsty? I’ve got some juice for you to try.”
Quartzy nodded eagerly, eyes wide. “Uh-huh! I would like some juice, daddy!”
Steel nodded, untangling himself from Quartzy and getting off the couch, stretching his wings a little before turning back to the earth pony. “Stay here then, I’ll go get the juice.” Quartzy gave an imitation of a salute and Steel left the room, chuckling.
He returned to the room some moments later, a tray in his teeth as he balanced a sippy cup of purple juice on it. He nearly dropped it in surprise, however, when he found that all the couch cushions and pillow had been arranged into a box-shape in the middle of the floor. Inside, Quartzy was peering out carefully, and had somewhere obtained a newspaper that had been fashioned into a crude hat. Steel blinked for a moment before lowering the tray to the ground. A full-grown stallion- no, a colt in a stallion’s body had built a couch-cushion fortress right in the living room. Steel had to stifle a chuckle.
“I'm a pirate, daddy! This is mah boat.” Quartzy gestured at the cushions with a hoof. However, his gesture was a little too wild, and he ended up knocking a cushion with a hoof, causing the entire thing to fall apart. He stared around at the fallen cushions with sadness before glancing back up at Steel. “It sank.” Steel could no longer hide his amusement and chuckled at the youthful display before nudging the tray forward to the earth pony.
“Hey, if you’re gonna get to see your nursery later, you need to drink your juice.”
Quartzy looked at the juice, then back up at Steel with wide eyes. “My nursery?” Steel nodded, and Quartzy picked up the sippy cup, looking it over carefully. “Grape juice? It looks a little funny, Daddy.”
Steel grinned. “It’s a special kind of grape juice. Go on, drink up colt, I promise it tastes good.” Quartzy needed no further encouragement and wrapped his lips around the spout of the sippy cup, draining the juice out with gulp after gulp before setting down an empty cup and looking back up at Steel. After a moment his eyes crossed and he belched loudly, startling himself in the process and falling over before erupting into a fit of giggles. Steel grabbed the adult-sized colt in a hug and quickly noogied his mane, causing Quartzy to squeal and laugh. After a few moments Steel let up and scooped his colt up in a hug. There was just one more thing to do. “So champ, ya wanna see your nursery?”
Quartzy gave a stifled squeal, his eyes wide as he furiously nodded. “Yes, daddy! Yes! Can we go right now? Please? Pleeeease?” He nuzzled at Steel, pushing his lower lip out in a pout as his ears splayed. Steel stifled a chuckle at the display.
“Yeah, yeah, come on now, don’t pout…we’ll go there right now.”
“WOW! Daddy, all this is mine?” Quartzy stared around at all the sights in the room. The majority of the room, from the stain-resistant carpet to the thick blackout curtains covering the windows, was powder blue and covered with a motif of horseshoes and pacifiers. Tucked into the corner was a toy chest filled to the brim with a variety of pleasurable things, ranging from board games and plushies to dildos and anal beads. Across from that, dominating the wall opposite the windows, was a large crib, big enough to hold a full-grown stallion or several colts. Above it hung a mobile of shapes and small plastic stars and planets, each painted a different color. A small red rug lay on the carpet at the foot of the crib, decorated with several generic colts playing a game of hoofball. A gryphon weeble-wobble stood guard over a pile of plushies placed in the corner between the crib and the far wall, and opposite that near the windows was a small set of brightly-painted shelves covered in figures of dragons and many books for young ponies to read. Around the walls were posters for a variety of entertaining adventure stories, magic shows, circuses, and flight teams- sure to fill the head of any colt with dreams of adventure, fame, and fun. The center of the floor was dominated by a table low to the ground, arts and crafts supplies arranged neatly in drawers underneath it. Immediately next to the doorway where the two ponies stood, a wardrobe stuffed with cute outfits sat. Next to that, a pastel peach and blue highchair was tucked into the corner, awaiting future use. The touch that pleased Steel the most, however, was that the carpet would repel fluids and was enchanted to forever fill the room with the smell of baby powder. Quartzy was unconcerned with stain-repelling carpet, however, and merely stared in marvel at the most wonderful room that, at least while in this state, he had ever seen. On top of all these things that sparkled and glinted like new under the slowly rotating Wonderbolts racing-figure chandelier, scattered about were toys, plushies, and a few unopened packages. Quartzy was a colt in a candy store, figuratively speaking, smiling wide as he surveyed the room.
“Yup, it’s all yours colt. I’ve even got a few presents for you scattered about. In fact, you should go open that big rectangular one by the toy chest.” He nudged Quartzy with a hoof, but that was unnecessary- The adult-sized colt needed no prodding and bounded immediately across the room, stopping only to determine if the present was fragile before rapidly ripping off the packaging. Steel slipped out of the nursery momentarily to retrieve the packages from earlier in the day. He was pleased that the crib had been delivered and assembled before they had gotten there, but he wasn’t sure that it would be used all that often, at least not that night. As he returned with the day's packages, Quartzy was lifting a pair of green stallion-sized footed pajamas decorated with starbursts out of the box.
“Wow! These are so cool!” Quartzy looked over to his daddy and grinned. “Can I put them on, daddy?” A light went off in Steel's head- Sure, he had a plan to make Quartz a colt in body as well as mind, but what harm would delaying that for a little game do? He nodded to Quartzy.
“Yes, in fact, you should put them on right now. We're gonna have a little scavenger hunt with all the presents.” Quartzy gasped and quickly tossed the pajamas on the floor before pushing his head in through the rear flap, wiggling into the pajamas like they were a large bodysock. As he poked his head out and got his legs into all four sleeves, Steel joined him, smoothing out the fabric and closing the rear flap after ensuring Quartzy's tail would hang free. He peeked under the colt-minded-stallion and grinned as he saw a zipper on the pajamas between Quartzy's hind legs. The material of the pajamas, soft and flexible, was tented slightly by the altered pony's ever-full sheath and large sac, but it would be unnoticeable in public with a diaper. Steel grinned even wider- He loved the thought of putting his colt in a diaper and taking him out in public. Nopony but him would know that the colt was always in a state of light arousal, shaft peeking slightly and testicles forever plump and loose. As Quartzy got the pajamas completely on, Steel was already contemplating which present to have the colt-minded-stallion go for next.
“Say, Quartzy, do you see that little box with the bow? On the table with the art stuff?” Quartzy nodded, prancing a little in place in his new pajamas. “Why don't you go open it?” Steel admired the colt-minded-stallion as he pranced over to the table, quickly opening the box to reveal a pacifier. However, the nuk of the pacifier, the part that would be sucked on, was larger than usual and in the shape of a stallion's shaft. Steel grinned as Quartzy gave him a confused look. “Go on, try it out, then you can open the next present.”
Quartzy gave the pacifier a look and poked it gently with a forehoof before picking it up and slowly sucking the rubber cock-shaped bulb into his mouth. As his lips and tongue wrapped around the nuk, the familiar texture and shape of the cock-impersonating pacifier struck a cord in the colt-minded-stallion’s mind, and he began suckling on the pacifier in earnest. Steel chuckled as the colt-minded-stallion looked back at him, pacifier bouncing under each suckle, and motioned a hoof to the bag next to him. “How about we skip the minor presents for now and get right to the big one? You like rocks, don’t ya Quartzy?”
That rung a bell. Quartz’s special talent was geology, and while his adult mind was sealed away, it certainly wasn’t gone. Quartzy nodded his head rapidly, trotting over to his daddy and peering curiously at the bag. Steel grinned and ruffled his mane with a hoof before reaching into the bag and pulling out a long tubular object wrapped tightly in bubble-wrap. Quartzy’s eyes went wide, the pacifier hanging limply from his mouth. Steel caught onto the train of thought, however, and shook his head.
“No, you can play with the bubble-wrap later. It’s what’s in the bubble-wrap that counts. Do you remember the carving store we went to earlier?” Quartzy thought for a moment- there was a vague memory of visiting a place with his daddy that had lots of statues. He assumed that was the place and nodded his head, suckling quietly on the pacifier again. “Good. This is what I picked up there.” Steel slowly unwrapped the tubular object, casting the bubble-wrap aside- Quartzy groaned a little- and setting the tubular object on the carpet between them. Quartzy stared at it for a moment, then looked up at Steel, then back down to the object. It was a heavy clear piece of crystal carved into an enormous equine phallus, larger even than his daddy's. Quartzy softly suckled the phallic pacifier in his mouth as he examined the crystalline cock. The large base was frosted, almost opaque with the degree of sanding that had been done to it, but the shaft itself was perfectly clear and flawless, like polished ice. Every vein, ridge, and minor curve of a stallion’s shaft had been captured perfectly in the stone, and Quartzy’s mouth watered a little around the pacifier. The final touch was a series of letters carved into the frosted base- the colt-minded-stallion picked up the crystalline dildo to get a better look. A brief spark of adult knowledge returned, and Quartzy giggled; his name was carved into the dildo! Steel slid up next to him, a wing draped over his colt’s back.
“It’s quartz. The crystal, I mean. I thought you’d like that.” He smiled warmly at the colt, nosing Quartzy’s mane as the earth pony continued to examine the crystal dildo. “I actually have a couple more gifts for you, ya know…But I wanna play a game with you first.” Quartzy’s eyes snapped to Steel’s, and the pegasus grinned. “I want you to turn around and lift your rear a little. I think you’ll like this game.” Quartzy did as he was told, turning around and raising his tail end up. He wasn’t sure what kind of game this was, but a trickle of thoughts from the magic that had altered his mind told him everything he needed to do: To lift his tail, spread his hind legs, stand still, and relax. The crystalline dildo fell to the carpet and rolled away unharmed, no longer the focus of the colt-minded-stallion’s attention as instincts took over and he presented his rear for Daddy. This was going to be a fun new game.
“Oooh, Quartzy is an eager colt, hmm?” Steel grinned, undoing the rear flap of Quartzy’s pajamas. The magic had done a few more things to Quartz other than suppress his mind- His tailhole was now a soft, sensitive little pucker, a perfect glove for any stallion’s cock. Before, it had been tight and small, almost never penetrated, but now it looked like soft and inviting, eager to accept a cock of any size. Steel couldn’t help grinning as he pulled a tube of lubricant from the bag and squirted some on a hoof. “This will work nicely…You just stand still Quartzy, let daddy take care of everything.”
He began rubbing the hoof over the fuckhole presented to him, finding no resistance as he began to gently spread it open, wedging the rim of his hoof into his colt. Steel could feel Quartzy shiver, every little motion and squirm the earthpony made telling Steel that he loved it, and if his mouth wasn’t full he’d be pleading for Daddy to fill his rear. The flesh of the earth pony's pucker was surprisingly malleable, shifting around the hoof with ease as Steel obliged, slowly pushing his hoof into the colt-minded-stallion.
Quartzy moaned around the pacifier in his mouth, eyes closing as pleasure overtook him. He had no clue what to call this game, but he loved that Daddy was playing it with him, and he wanted more. His groin stirred to life in his pajamas, his already-heavy testicles filling out a little more as his cock began to peak from his sheathe and dribbled precum, slicking them up and causing a shiver to pass through the pony’s body as his shaft slid into the cloth prison. The pajamas tented, but cradled his length snug against his belly and stained dark as the fluid dribbling from him begin to soak through.
Steel grinned, flexing his wrist as he shoved his forehoof deeper into the squirming colt-minded-stallion. He could smell the precum and arousal through Quartzy’s pajamas and didn’t need to look to know that his earth pony’s sizable shaft was trapped, gliding between slick cloth and bellyfur and teasing the poor little colt further. He didn’t need to look at all, but he did, and the sight of a bead of precum forming on the underside of a stained tent in the fabric brought a grin to his face. It wouldn’t be long at all now, he just needed Quartzy to cum and the final bit of magic would make him a colt forever…well maybe not forever forever, but Steel did like the idea of ‘losing’ the antidote for a few weeks or months. He flexed and pushed his forehoof a little further into Quartzy, teasing the colt-minded-stallion a little further before slowly withdrawing- he didn’t want Quartzy to cum just yet. Quartzy gave a disappointed groan around the pacifier, causing Steel to chuckle. “Don’t worry, the game isn’t over yet…” Steel grinned a little as he applied a little more lubricant to his hooves before sitting back on his haunches and slathering it onto his stallionhood.
Quartzy waited patiently, suckling intently on his pacifier and waiting for Daddy to play some more. As things were, the earth pony was in love with the game so far. If there was a way to make it better, he wasn’t sure, but obviously Daddy had something planned. He didn’t have to wait long, however, and the earth pony gasped as the pegasus behind him suddenly settled on his back. He felt something prod against his tailhole and a shiver went through his body- The game was starting again!
“I’ve got a couple more surprises for you Quartzy,” Steel began. “You’re a little big for a colt, so I got something whipped up that’ll make you small.” There was a questioning sound from the colt-minded-stallion, but Steel silenced it by slightly pushing his shaft against the earth pony’s pucker. “You see, you were a big pony before, but I figured you needed a little break from all that work and stress, so I made you my colt.” He paused a moment and let that set in- Quartzy was giving him a curious expression over his shoulder as he continued to suckle on the pacifier. Slowly, Quartzy began to remember his life prior to that afternoon, but his mind was having trouble processing it as Steel gave a big grin at the colt-minded-stallion. “That’s right, you remember all that now, don’t you…but isn’t this much more fun? Don’t you want to be my little pony for a while, and just be happy here with me?” The soft sound of suckling slowed as the colt-minded-stallion mulled over all his returned memories and the question posed to him.
Quartz’s mind- no, Quartzy’s mind reached an answer to the question quickly. His memories might have been unlocked, but he was still very much under the spell of the stallion mounting him, and he nodded his answer quickly. Steel grinned and began to sink his shaft into Quartzy’s fuckhole, eliciting a groan of submission out of the colt-minded-stallion, the pacifier hanging limply in his mouth.
The pegasus’ wings flared out, and the earth pony beneath him let out a sharp inhale. Steel began to thrust, his hips pistoning his length into Quartzy's rear and sinking it a little further into the colt's pucker each time, until hips met hips as he hilted his length in the colt-minded-stallion's pucker. Steel was in heaven, panting as he lay across Quartzy's back. The potion's effects were thorough in the transformation of the earth pony's rear as it clenched and trembled around Steel's shaft, milking at it with experience the earth pony had never known. Lifting himself up slightly, Steel groaned softly as he began to withdraw and thrust again, his heavy sac slapping against the cloth covering Quartzy's own.
Quartzy's mouth slipped open into a moan carrying twin tones of lust and innocence, and the pacifier dropped to the floor, forgotten. “Oooh, daddy! T-this feels really good!” The feeling of his tunnel parted and filled this way was alien to the younger-minded stallion, and yet memories of prior experiences with Steel surfaced, telling him that this was right. Being below his daddy and filled so perfectly was where Quartzy belonged as a colt. His shaft throbbed beneath him, each thrust into his rear coaxing another dribble of precum from his shaft. The colt-minded-stallion gently moaned again, pushing back into the heavy weight of the pegasus on his back, eager for the game to continue.
The two continued this for several minutes, Steel relishing the moans and sounds of innocent lust coming from his colt. His thrusts grew in intensity, drawing out to the medial ring and letting that stretch the earth pony's pucker before slamming back in. At times he paused as Quartzy shuddered, not wanting to drive the colt over the edge too soon. He would pant and, with a flap of his wings, withdrew to the flare before thrusting his length in as far as he dared, drawing loud pleasured yelps from the earth pony. Neither could last much longer, however. Quartzy's young mind was blank with pleasure as his shaft flared and twitched inside his pajamas, and each thrust was only driving him closer and closer to the edge.
“Last c-chance, colt.” Steel inhaled sharply, his thrusts coming fast and hard as he wrapped his forelegs around Quartzy's chest for support. “You wanna be my colt forever? You want to cum and fill those jammies with everything you were, leaving nothing but a little cocksucker behind?”
Quartzy grunted in delight, clenching around the shaft spreading him open. “I do, daddy! I do!” His posture shifted, a forehoof lifted to his chest as he tried to back against Steel's hips, eager to feel the entire length spreading his tunnel with each thrust.
Steel snorted, his wings flared wide with dominance and pride as he tossed his head. “Then do it, colt. Cum for daddy!”
Something inside Quartzy broke at that moment, something unidentifiable to the lust-addled colt as his adult mind slipped out of his head entirely for the second time that night. His sac surged and his shaft flared as he began to cum. With each pulse of cum, the earth pony's adult mind was eroded and washed away, his life before that night destined to be nothing but a dream. Quartzy moaned, the purest moan of bliss and innocence he had given that night, as his cum soaked into the pajamas he wore and smeared against his cock, stimulating the colt further.
Steel felt Quartzy shudder and clench around his length, and the pegasus snorted again. He could smell the light pumpkin scent of the earth pony grow stronger and heavier, and he could feel the magic of the last potion taking effect. A brilliant flash of light shone through the flanks of Quartzy's pajamas as Steel drove his flaring length deep into the colt's tunnel again and again, and that was it. Quartzy's cutiemarks were gone, and with that, Quartz was gone as well. Steel hilted himself in Quartzy's rear and began to cum, filling his colt with daddy's cream. As he held Quartzy with one forehoof, he planted the other to the ground as Quartzy moaned out, but this time it was something new. Quartzy did not just sound like a colt in a stallion's body, but sounded younger. Steel gasped as the pucker around his shaft began to tighten, and watched as the earth pony beneath him began to shrink.
Quartzy did not feel his cutiemarks fade away. He only felt the bliss of his daddy on top of him, the rhythmic swaying of his daddy's testicles against his own, and the heavy thrusts of his daddy's cock into his tunnel. The earth pony moaned out, unaware of the change in his voice. His shaft was pulsing hard, jet after jet of cum splashing against the inside of his thoroughly stained pajamas, and it did not seem to end. Quartzy did not want it to end. Each pulse of his prolonged orgasm drew more and more out of him, and with it, Quartzy began to shrink. He squirmed around his daddy's shaft, moaning as the length seemed to grow inside him. Years were stripped off of the enchanted pony with every pulse of his shaft, with every burst of cum that threatened to further ruin his pajamas, and his frame retracted. His voice was high and young, his coat soft and unweathered, and he was in heaven.
Steel panted in afterglow, rocking back onto his own haunches and holding Quartzy tight against his chest as the former stallion regressed through puberty and into his colthood years. The pegasus stallion watched, one of his hooves tracing along the tent in the front of the colt's pajamas, smearing the cum that had soaked through them across the front and teasing the colt's cock further. The pajamas had been specially enchanted for just this occasion, and shrank with Quartzy as he was reduced to a school-age colt impaled on his daddy's length. Steel took a moment to collect his thoughts, his mind racing with possibilities as he cuddled his little pony. “Mmrf, you really like this, don't you?”
Quartzy slumped against his chest, staring up at him with bright eyes and panting heavily as his orgasm finally came to an end. The front and underside of his pajamas were thoroughly soaked, an entire lifetime expelled as nothing more than cum, but the colt didn't care at all as he squirmed playfully around his daddy's cock, slowly trying to work himself down onto it to take the whole length once more. To Steel's surprise, the colt did so with ease, his body still perfectly primed for sex despite his young age.
“Yes daddy, I like it a lot...” Quartzy huffed out in satisfaction, his tail twitching against Steel's belly as he clenched again around the pegasus pony's length. “It's so warm and fun...I feel really good. Can we play this game every day?” He looked up at Steel with questioning eyes, large and full of youth, and Steel melted a little inside.
“Of course we can. We'll play this game every day, and several more games I'm sure you'll love.” Steel smiled warmly, tilting his head down to kiss his colt on the snout. “You'll be daddy's little colt forever.” He sighs in tired bliss and looks around the nursery before chuckling, rubbing at Quartzy's still-hard length through the soaked pajamas that struggle to restrain the colt's erection. “What do you think about having a brother, though?”
Quartzy beamed up at his daddy. “I'd like that a lot!”
Author's Note
This story was initially based on a roleplay I did with my friend Jimp years ago. I've considered doing more things with these two, or possibly with Quartz and my friend's new pony Thought Blossom. Lemme know what you think!
