Cobalt walked quietly beside Strong Hoof, doing his best not to glance back at his suddenly sore rump. It was more surprise than pain, but he found that, the more he thought about the prince’s little tease, the more blood rushed to his face. His tail swished back and forth, and he had to look toward the walls to hide the goofy smile spread across his muzzle.

As they continued down the hall, the large stallion at his side finally spoke up.

“So, I see the cutie mark, but you seem like a nervous type.” Strong Hoof glanced down at him. “So why the guard? You look more like a playmate to the prince than a guard.”

“Sorry,” Cobalt said, wilting slightly. “I just stayed on the farm most of the time at home, you know? There was always work to do, and if we went to town it was to sell, so I didn’t spend a lot of time socializing. Now I’m in the capital, among the royals, and finally achieving my dream… it just makes me nervous.” He let out a deep breath and did his best to straighten up. “I’ll do my best to firm up.” He looked to the pegasus. “Will proper guard persona be in the training?”

“Indoctrination,” Strong Hoof corrected, “and you’re partially right, I think. You’re close to a lot of new ponies, that much is just fact.” He grinned, and his eyes took on a hungry light. “What I think though, is that it’s drawing out a certain something in you. Would you mind if I ran a little test to confirm my theory?”

Cobalt shook his head.

“Not at—eep!”

He found himself on his back and the stallion towering over him. Hooves rested on either side of his head, and warm latex pressed against him from above, drawing out a moan as it rubbed against his stallionhood, drawing it from its sheath. Strong Hoof glanced down and chuckled.

“That didn’t take long.” One of his hooves rose and made a circular motion. “Turn over for me, recruit. Show me that bowing you’re so fond of.”

He eased up just enough for Cobalt to roll onto his belly, and the bat pony felt a certain thrill as he wordlessly obeyed the larger stallion’s order. He pushed his rump up and glanced back at Strong Hoof. He moaned as the pegasus’ muzzle pressed against his neck. Strong Hoof took a deep breath, savoring his scent, then his grin took on a wicked look as he brushed Cobalt’s tail aside. Cobalt squeaked as a gentle pressure ground into his tail-hole, and he moaned again, his mind alight with pleasure. He… It was going to happen. He was about to be taken by a stud of a stallion, practically a stranger, yet at the same time, somehow familiar. It was the latex, so warm, pressing down on him from above. It made him feel so much closer to his new companion, so much more akin to Strong Hoof than he’d been with anyone in his life. He let out a whimper of need as glanced back with pleading eyes toward the dominant pegasus.

Strong Hoof chuckled in his ear.

“I thought as much; you’re a natural bottom, not even suited and already begging to be played with. I think you’re going to fit in with the guard just fine Cobalt, or rather, we’re going to be fitting in you.” He nibbled Cobalt’s ear, causing the bat pony to shiver with delight. “So, just for my own curiosity, first time with a stallion?”

“Y-Yes!” Cobalt gasped, trying vainly to press back against what he could only imagine was the stallion’s rubber covered cock teasing his tail-hole. His body was alight with little pleasures and was all but screaming at him for more. The scent of the stallion above him was slowly filling his nose, and he couldn’t help but savor the scent as it mixed with the rubber of the stallion’s suit. Was this how all the guards were, or was he just lucky to have one that was so strong? Either way, he couldn’t help but whine again with desperate need as he squirmed and tried to press back. “Please…”

“Definitely a bottom,” Strong Hoof chuckled, keeping him firmly in place. He rocked back and forth just enough to continue teasing him, drawing out more needy whines and squeaks from the bat pony beneath him. “Now, have you been with a mare before, or are you just a desperate little toy, begging to be rutted by every stallion and strap-on in sight?”

“I-I’ve been with a mare!” Cobalt sputtered. “I… I just…”

Further words failed him as a rubber clad hoof stroked his mane.

“Shhh, don’t worry, I’m not trying to humiliate you, I’m just asking.” Strong Hoof nuzzled his neck and took another whiff of his scent. “Queen Lunaris assigned you to be my partner for a reason, and I want to know how much I’m going to have to share you.”

“H-how much? Not if?”

Strong Hoof chuckled, and Cobalt felt himself relax even more as his hoof continued to run through his mane.

“All the guards are toys at the whims of the Queens, Princesses, and Prince, save for the odd exception or two. Adorable little bat like you? I’m surprised they didn’t scoop you up as soon as you walked in.” He chuckled again. “They do like their bats.”

Strong Hoof leaned on him more, slowly pressing him down so that his cheek rested against the floor. Cobalt started to ask why, then let out a sharp gasp as the pegasus’ other hoof gently touched the head of his cock. Strong Hoof hummed and made light circles with his rubber-clad hoof, slowly following Cobalt’s cock as it grew to its full length.

“There is one warning I’d like to give you before we move on,” Strong Hoof said, slowly beginning to stroke. Cobalt felt his hind legs shake as the pressure on his tail-hole slowly increased, and he let out another, far louder, moan. As much as he wanted to, he couldn’t move at all, and was forced to simply submit to the larger stallion’s teasing as he continued to speak. “Your nurse is going to know what I just confirmed, and she’s going to ask you questions about just what kind of suit you’d like to wear. In particular, she’s going to assume certain access…” Cobalt moaned as his tail-hole began to stretch to allow its new guest, only for Strong Hoof to chuckle and pull back. “and she’s going to ask about this toy down here…” Strong Hoof slowly traced a line down Cobalt’s cock, forcing the bat pony to buck in reply, dripping pre-cum on the floor. “I’ll bet the mare you were with before loved spending the night with you, so if you don’t mind, I’d like to make a suggestion.”

Cobalt whimpered and nodded, his brain too hazy to conjure words. He felt so close, yet so far from cumming. Strong Hoof was a master at teasing, and some isolated part of his mind wondered if he’d made a mistake, if he was going to be teased and tortured forever. Still, if it felt even half as good as the lust he was lost in now, it was worth it. All of it was worth it.

“Yes…” he finally managed to hiss out.

“I think Queen Lunaris intends to keep you as a playmate for the prince in your off time, so for that, I’d recommend making every piece of you available,” Strong Hoof said, continuing to stroke softly. “Including this hole-stretcher you’re hiding down here. For me though, I’d like a little something different in my adorable little bat pony partner.” His breath warmed Cobalt’s ear as he spoke at a whisper. “For my little bottom bat, I’d like your guard suit to be fitted with a null bulge. You’ll grind, and whine, and beg for release, but the only way you’ll get it is with service.” Cobalt felt his cheeks flush lightly as the pegasus planted a kiss in his mane. “I’ll make sure to use you every single day, just like I know you want.”

He hummed and withdrew slightly.

“But then again, I don’t want to impose, and I’ve been doing an awful lot of the talking. So let’s hear what you want, my adorable little bat.” Cobalt looked back and noticed the wide grin on the stallion’s muzzle. “Let’s hear you say; “I want to be a rubber slave”. You came to be a guard, but are you ready to be a servant? To be wrapped in rubber, teased and tortured endlessly with no control over when you get release? If that’s what you want, then you’re going to have to say it for me. I won’t give you a thing if you don’t want it.”

Cobalt’s eyes widened with panic as the stallion slowly started to pull away, and his muzzle flapped open, spilling out his words all-too-desperately.

“I do!” he cried. “I-I want to be your rubber slave!” As he spoke, he could feel the panic burning away under a tidal wave of renewed lust. He’d said the words aloud and now he needed to go further, to make his exact thoughts known. “I don’t just want to be your slave, I crave it, need it!” He pressed back, trying to feel the warm latex pressing down on his back once again.

Luckily for him, Strong Hoof was more than willing to accommodate, once again settling his weight on Cobalt’s back, driving him to the floor. Cobalt moaned as he felt the rubber once again through his fur. He almost came as a squeak sounded in his ears. Strong Hoof took one of the fluffy appendages in his teeth and nibbled on it.

“Good bat, I can tell you’re being honest.”

Cobalt smiled, ready for the pressure against his rear to return, only to let out a squeak of alarm as Strong Hoof pulled away entirely. His cock twitched with desperate need, continuing to drip hot pre-cum on the stone floor, and he let out a whine that matched it. Strong Hoof met his pleading eyes with a smile and let out a chuckle.

“Adorable. Come on recruit, let’s not make you wait anymore. Your proper position waits.”

He moved forward, leaving Cobalt still panting, rump in the air and waiting in a pool of his own pre-cum. The blue bat pony stared after his new partner for a long moment, then did his best to stand on shaky legs. He stumbled after Strong Hoof, managing to catch up, but stumbling into the pegasus in the effort. Strong Hoof let out a chuckle, steadying him by throwing a hoof over his withers and pulling him close.

“Careful there little bat. Don’t want you to have to report to the infirmary before you even get dressed.”

Cobalt blushed and stared at the floor as he tried to will his knees to stop shaking. With the amount of lust filling him from head to tail, he wasn’t entirely sure it was possible, especially since his new partner felt and smelled so wonderful. It took everything in his power not to simply fall onto the pegasus and get lost in the sensations his rubbery bodysuit offered him.

“S-sorry,” he managed to mumble.

Strong Hoof took notice and nudged his chin with his muzzle.

“Eyes up, recruit, and don’t be nervous. If you made it this far, it means that the prince likes you, and the queens like you.” His encouraging smile held a touch of lust as he chuckled again. “And I hope it brings you some comfort to hear that, as your assigned partner, I definitely like you.”

The last words were purred in his ear, and Cobalt found that he did relax slightly at the words, leaning into the larger stallion.

“Thanks, I, um, like you too?”

Strong Hoof let out a snort and shook his head, smiling.

“We’ll need to work on your confidence and flirting, but you’re lucky you're a cute little bat.”

They came to a door, which easily opened to reveal a small, circular room. On one wall was a large screen, while on the opposite was a large wooden x with leather straps on it. At the center of the room was a table and chair, at which sat a lavender bat pony in a purple and red bodysuit. A pink cross with a crown at its center sat emblazoned on her flank, and on the rubber nurse's hat resting in her mane. Her golden eyes flicked up as they entered, and a warm, yet somewhat mischievous smile spread on her muzzle.

“Why Guardspony Strong Hoof? What a pleasure it is to see you. It’s been awhile.”

A squeak came from his left, and Cobalt glanced over to find Strong Hoof frozen in place, his eyes straight ahead. Pressed against his side, Cobalt could feel the reddish pegasus shaking in place, but if that was from fear, or from something else, he couldn’t tell. He looked back to the lavender bat pony to find her grinning at him. Something in her eyes made him shy away nervously, causing her to chuckle.

“Guardspony, don’t be rude. Cobalt is the guest of honor today and you’re ruining his entrance.”

“O-of course Nurse Lavender,” Strong Hoof sputtered.

He quickly stepped deeper into the room, pulling Cobalt with him. The blue bat pony felt suddenly exposed as the welcoming wing left as Strong Hoof spun around, closing the door behind them, before he moved off to the side, and again resuming his straight-backed, quivering posture. Cobalt stared at his suddenly tight-lipped companion, then looked to the apparent source, unable to hide his own nervousness. He was nothing without his manners, however, and he trotted forward, extending his hoof.

“Hi, I’m Cobalt, but I guess you already knew that.”

Cobalt felt momentarily proud of himself for not stuttering. Nurse Lavender smiled and shook his hoof with her rubber clad one.

“As I’m sure you’ve heard mine as well, but I am Nurse Lavender Blossom, or Nurse Lavender to most, and since Nurse Grey Horn fell ill this evening, I will be taking care of your training.” She clicked her tongue and glanced in Strong Hoof’s direction. “You spoiled our introduction, Guardspony. That’s one punishment.”

Strong Hoof closed his eyes and shuddered, though to Cobalt, it didn’t look like the pegasus was all that displeased with the news. He looked questioningly to Lavender, who winked.

“Don’t worry about him, he just gets like this because I was the nurse during his induction as well. I was, and am still certain he’s a switch like you; just dominant leaning instead of sub.” She sighed. “He falsely believes he’s a dominant only though.” She tilted her head as she again looked toward the pegasus. “I’ve been meaning to spend some time re-educating him, but he’s a crafty one, and I have other duties, for the moment at least.” Her fangs shined and she chuckled. “He can’t run forever, and technically speaking, I could involve him in your indoctrination, train the pair of you up just right…”

Strong Hood whined and ever so slightly shook his head. Lavender scoffed and rolled her eyes, smiling as she looked back at Cobalt.

“He’s far too easy to tease,” she whispered. She strutted forward, flicking Cobalt’s nose with her tail as she took his saddlebags in her teeth. They flew through the air, and Strong Hoof grunted as they smacked into his face.

“Please stow these in your partner’s locker and get him a latex pair,” Lavender ordered. “Just because the latex is magical, doesn’t mean I will tolerate burlap on her Majesty’s guardsponies.” She shuddered. “It’s just wrong on so many levels.”

Strong Hoof let out a sigh of relief and snatched the saddlebags from his muzzle.

“Of course Nurse Lavender. Was there anything else?”

Lavender threw a small pouch to him as well. Cobalt faintly heard the rustling of bits as the pouch smacked into Strong Hoof’s nose.

“Cobalt’s first month of pay up front, but seeing as he will be busy, you get to spend it. Get him some nice things for his room, make sure it’s homey.” She looked at Cobalt as she spread out some papers on the table. “You’re from a mango farm, right? What colors do you like?”

Cobalt blinked, then looked to the ceiling in thought, noticing a large crystal suspended from an iron bar.

“Well blue, obviously, but I guess… green, red, orange, and… yellow.”

Strong Hoof blinked.

“That’s a pretty wide spread.”

Lavender sighed and pinched her brow with a hoof.

“It’s the color of a mango, Guardspony. If he wasn’t from a mango farm, I’d punish him for being too stereotypical.” Shaking her head, she looked at the forms. “There are a few shops in the old town that are bat pony themed, you can’t go wrong. Now out, or I start making two toys tonight.”

Strong Hoof turned to leave, but Lavender clicked her tongue again, freezing him in place.

“Before you go, congratulations are in order Guardspony. I can tell her Majesty’s hunch was right, and you’ve needed a good bottom slave for months now.”

Strong Hoof finally recovered some measure of his confidence and he half-turned, his muzzle curling in a smile.

“I wouldn’t count that chicken too early Nurse Lavender. You’re assuming Cobalt here hasn’t just been playing with me, hiding some dominance away for later. He’s packing more than a little heat, and he’s been with mares.”

“Are you implying a mare can’t be dominant?” Lavender asked, one eyebrow raising.

Strong Hoof quickly shook his head.

“No, Nurse. No I am not.”

“Good, I was about to lock the door and teach you a proper lesson.” She looked to Cobalt, eyeing him up and down. “As for our newest bat… maybe a little switch, but mostly bottom.” She moved toward Cobalt. “You’re going to be a good little slave for your new master, aren’t you?”

Cobalt blushed and looked down, still feeling a tad nervous about his answer.

“I… I don’t-”

A rubber clad hoof touched under his chin and forced him to look up. Meeting the nurse’s eyes, he found them to be hypnotic, and he couldn’t help but sway slightly as he lost himself in those golden depths.

“You’re going to be a good little slave, aren’t you?” Lavender repeated, her voice quiet, yet firm, all but ordering an answer.

“Yes, Mistress,” Cobalt mumbled.

She smiled and kissed his nose, sending a jolt of joy down his spine.

“Good bat.” She looked over his shoulder. “Run along Strong Hoof. He’s more than ready to start.”

Strong Hoof let out a chuckle, drawing Cobalt’s dazed eyes. The reddish pegasus gave him a wink as he opened the door.

“Have fun Cobalt. I’ll be back for you when you’re done.”

Cobalt blinked at the pegasus, vaguely aware that he was supposed to say something.

“Thank you,” he mumbled.

He heard the disappointed click of a tongue and he turned, immediately dropping further in Nurse Lavender’s eyes again. She smiled and stroked his cheek.

“What else do we say?”

Cobalt simply stared at her, what little of his brain function stuck spinning in circles, unsure of what he was missing. The nurse noticed his confusion and giggled.

“Good bats say; ‘thank you Master,’ or ‘thank you Mistress,’ when addressing their dominant.” She nodded toward Strong Hoof. “Now go on. Thank him properly.”

Cobalt looked to Strong Hoof.

“Thank you, Master.”

Strong Hoof snorted and shook his head.

“Please don’t break him. He’s already fun to toy with and he’s going to make guard shifts so much more enjoyable.”

“No promises,” Lavender sang. “The dungeon always needs more mindbroken rubber slaves, but don’t worry. I think Cobalt won’t disappoint.”

Spending a moment without staring into Lavender’s eyes, Cobalt recovered his faculties somewhat. He closed his eyes and suppressed a moan of delight at being hypnotized so easily. It was every dream come true… He noticed that something felt different in his head. Like something small had been added, an urge almost. On impulse, he decided to act on it.

“T-thank you for the compliment, Mistress.” He looked shyly at Lavender. “I hope to not disappoint.”

Her hoof again nudged his chin up, and she again caused him to sway in place, hypnotized by her gaze.

“Take your time shopping. I’m going to enjoy training this one.”

The door closed with a soft swoosh, leaving the pair alone. Lavender brushed Cobalt’s cheek, moving so that they were nose to nose.

“Such a cute little bat,” she said, towering over him. Cobalt faintly recognized that he was nearly a head shorter than the mare. “Go lay on the table so I can get your measurements.”

“Yes, Mistress,” he dutifully replied.

“Crafting your suits will take some time, which we shall spend making sure you are fully trained up and ready to participate in the dungeon,” Lavender said as he climbed onto the table and laid on his back. “The process should take a few days at minimum, so plenty of time to get you just right.”

“D-days?” Cobalt stuttered, his wings flapping as he settled down. “Will there be breaks?”

Lavender seized one of his wings in her hooves and spread it wide, taking a measuring tape from beneath the table.

“Keep your wings out, we need to make sure the binders will fit,” she said. “If you’re concerned about safety and health, don’t be. I will be right here the entire time monitoring both your training, and your vitals. There is nothing in this world that can interrupt us aside from the queens themselves, and I have indoctrinated plenty of ponies before you without issue.” She smiled and patted his head as she moved around the table, measuring his other wing. “Just relax and enjoy yourself. You’re going to make a fine guard, and an excellent partner to Strong Hoof.”

She moved down to his legs, then slowly made her way up, measuring every limb on the way. Cobalt squeaked as she seized his cock and stroked it, bringing it to its full length. It didn’t take much, the mere touch of latex enough to make him moan. Lavender nodded approvingly as she measured it, then continued on, leaving Cobalt once again without any satisfaction.

“So, are you excited?” she asked, wrapping the measuring tape around his neck. “Hoping for anything in particular?”

“I’m really excited about combat training,” Cobalt said. He grinned sheepishly as embarrassing memories filtered through his brain. “I’m afraid practicing with a stick against a sack of grain just made me look silly more than actually teaching me to fight.”

He snorted as a pencil smacked his nose, and he looked to find Lavender grinning and shaking her head at him.

“I could not have been any more clearly asking about what will occur in this room you silly little bat.”

Cobalt blushed and looked away.

“Oh, well, I’m really excited about getting my own suit, and…” He looked up at the crystal hanging from the ceiling. “Does the training involve hypnotism? That…” he shuddered as her hoof returned to his cock, massaging it lightly. “That would be nice,” he squeaked.

“Be nice he says,” she chuckled. “I will definitely need to add some dirty talk to you, and to answer your question, we call it indoctrination for a reason. Large parts of your training include different alarm codes, suit meanings, and room locations, all of which will be installed in that pretty little head of yours using our various hypnotic methods. Things such as combat training will be covered with Strong Hoof after you leave my care.”

Lavender combed over her measurement sheet for a moment as she idly stroked his cock, causing him to quiver on the table, putty in her hooves. Humming in satisfaction, she set the page beneath the table and stopped stroking him, using her muzzle to nudge him to his feet.

“Alright Cobalt, let’s get started.

She moved to one of the walls and pressed, revealing a hidden compartment, from which she dragged out a crate. She pulled the box to the center of the room and opened it, pulling out a shiny black suit. She laid it on the table and nudged Cobalt toward it.

“Get dressed. You’ll get your full suit once you’re done with training.”

Cobalt nervously approached the latex suit, prodding it with a hoof. It came away slick, a sign that the suit was pre-lubricated. Gulping, Cobalt tried not to stress himself out with over-anticipation, and instead adjusted the suit so that he could slide his legs in. He settled his hind hooves in the rubber soles of the suit first, then his fore-hooves. Just as he turned to begin pulling the suit up his legs, Lavender was there. He let out a yelp as she smoothly pulled the latex up his rump, then moaned as she smoothed it out. She let out a chuckle, and as she finished with his rear, she moved to his front, pulling the suit up to his neck. Cobalt panted softly as she adjusted and settled the latex around his barrel.

Lavender withdrew and pulled his tail through a hole in the rear of the suit, drawing another moan from him as his cock and balls were naturally pulled through a hole in the bottom of the suit as it grew tighter around his body. She massaged his flanks again, seeming to enjoy his little moans and squeaks.

“Mmmm, you really are meant to be here, aren’t you Cobalt?” she hummed. “Just a little rubber slave pony, ready to be wrapped in latex forever.”

Cobalt breathlessly nodded, groaning as she took hold of his wings. She fed them through the wing holes, and prodded him silently to flap them, to make sure they fit comfortably. Satisfied, she again set to smoothing out the latex, leaving him at the mercy of the new sensations. It was just as he imagined. The smooth, squeaky rubber wrapped around him in a tight, ever present and wholly erotic hug, squeezing him in all the right places. He couldn’t help but squirm as Lavender drew the zipper up his back, slowly sealing him inside. He could feel himself pant as the zipper clicked closed, and Lavender locked it. She draped herself over his back and her hooves felt over his latex covered body, rubbing and teasing his new erogenous zones, which was to say; everywhere. It felt as if his fur had been replaced by rubber, and he squirmed as she nibbled on his ear and giggled.

“Such a handsome little rubber bat, what do we say?”

Her hoof teased the head of his cock and he jerked, leaking a spurt of pre-cum on the padded floor.

“T-thank you, Mistress!” Cobalt squealed.

Nurse Lavender dangled something from her wingtips in front of his eyes. It was a simple black latex collar with a crescent-shaped tag on it. On the tag read a simple; Rubber Slave in Training. Cobalt felt his cock twitch again at the sight of it.

“Now, my new rubber bat,” Lavender breathed in his ear. “This is your very last chance to leave. Once this is around your neck, you belong to her Majesty. As far as the law and the rest of the world is considered, you are hers and hers alone to do with as she wishes. I ask you one more time; is this what you want? Do you want to serve the Queen of the Night as her loyal guard and servant?”

Cobalt managed to have a clear thought pierce his haze of lust and desperation, but even that clear thought had only one word it wanted him to say.

“Yes!” Cobalt cried. “I want to be a rubber pony, I want to be a rubber slave!”

“As you wish,” Lavender purred.

She slowly pulled the collar tight around his throat, then a click that seemed to fill the room hit his ears. The sound of his destiny being sealed was too much for him to bear, and Cobalt couldn’t hold himself back anymore. He came, and he came hard. Cum splashed his belly as the force of his load splashed onto the floor, spreading rapidly in a sticky white puddle as his orgasm blitzed onward. Lavender bit her lip and moaned lightly in his ear as the scent of his cum filled the air, and she helped him along, slowly jerking him off.

Cobalt came harder than he had ever before in his life, and by the time he was finished, he was gasping and panting hard. Every nerve in his body felt as if it had been used, and despite the nirvana he found himself in, he also couldn’t help but feel exhausted. His legs shook as he slumped to the padded floor, uncaring that he was resting in his own fluids. Lavender chuckled and gave his cheek a kiss before pulling away.

“Welcome to the Lum Castle Dungeon, my little rubber bat. From now on, you will obey me and you will refer to me only as ‘mistress’, is that clear?”

“Yes Mistress,” he moaned, closing his eyes as he basked in the afterglow of his orgasm. His fangs peaked out as he grinned, idly aware that his rump was still stuck in the air, presenting an inviting sight to anyone standing behind him. “Thank you, Mistress.”

“You’re very welcome, pet,” Nurse Lavender said. “And you are forgiven for cumming without permission. I understand that this is your first time in latex, and well-” she bit her lip “truly you are a natural slave to cum at being put inside your suit and collar.”

She gave his rubbery ass a slap, drawing a moan from the blue bat pony.

“Savor this pet, it’s the last orgasm you’ll have until you see your master again. Now up! We need to start your training.”

Cobalt remained presenting in pure bliss for a moment longer, savoring the newfound pleasure of the stinging in his rump. He then slowly pushed himself up, his knees still shaking. He watched with fascination as the cum covering his chest and belly, as well as the cum on the floor, slowly seemed to stream away toward a drain in the center of the room. He faintly wondered if there was some sort of clean-up spell on the room. He didn’t spend much time on the thought however, as when he looked up and met Lavender’s eyes, he quickly found himself lost in her hypnotic gaze once more.

She chuckled and stroked his cheek.

“Enjoying yourself, pet?”

“Yes, Mistress,” he replied lovingly.

“Good bat.” She nodded toward the ‘X’. “Up. I will strap you in.”

Cobalt wandered dreamily over to the cross, feeling as if he was dancing on clouds. He stepped onto the raised platform and turned around at the nurse’s instruction. Lavender pulled a belt from the center of the cross and dragged it forward, strapping it around his stomach. She then moved to the back of the cross, a mischievous grin touching her freckled muzzle.

Cobalt let out a yelp as he was suddenly yanked backward. He squirmed slightly, looking down to find himself suspended by the leather band around his middle. His ears turned at a giggle from Nurse Lavender, who pulled gently on one of his forelegs. Trusting her completely, he simply let the limb be limp, watching as she raised it to one of the cuffs above him. Another strap tightened the limb in place, and she moved over to do the same with the other leg. While she did so, Cobalt tested his new restraint, trying to pull his hoof free. It didn’t budge in the slightest. Quickly his second foreleg was secured, then Lavender pulled his legs apart. As she moved across, she brushed his clock. Cobalt let out a needy moan as it bobbed, begging for attention. Lavender giggled and secured his hind legs.

“Sorry slave, but you won’t be using that for awhile yet. In fact-” she turned away, coming back with a black rubber sleeve “-you don’t get to use it at all during training. The only time you cum is at your Queen’s request, or if any of your playmates request it.” She patted his head. “Thank you for the reminder pet.”

Lavender turned the sleeve inside out, drawing a nervous gulp from Cobalt. Inside was a long tube, and the end of which were several black beads that got larger as they neared the head. As lust stricken as he was though, he couldn’t feel anything other than curious. Lavender watched his eyes carefully, and seeing no traces of panic, she smiled and stroked his cock.

“Good pet, deep breath now.”

Cobalt let out a whine as she guided the well-lubed catheter into his dick hole. The lavender bat pony was slow and methodical, taking great care not to go too quickly. Cobalt, for his part, whined and tried to squirm as his urethra was stretched. It was a new, strange pressure that only became more focused as the catheter was pushed deeper and deeper. Lavender paused as the first bead pressed against his cockhead, and she continued to stroke his cock gently.

“Tell me if this hurts too much,” she murmured.

Cobalt gulped, but watched as she slowly applied pressure to the bead. He felt a slightly unpleasant stretch as his cock struggled to accommodate the bead, then all at once, it popped in. Cobalt moaned and bucked in his bindings, the urge to cum and shove out the foreign intruder suddenly filling his body. Lavender smiled and slowly pulled the bead out, then drove it back in again. Over and over she pulled the bead in and out, gradually stretching his dick hole so that it could accommodate the larger beads. Cobalt moaned, whined, and humped as she did so, doing his best to try and cum. He couldn’t help it. He’d never even thought of experimenting with his cock in such a manner, and once she was plunging the beads in and out in earnest, it felt so good.

“Mmmm, I do love those noises Cobalt,” Nurse Lavender said, driving the second bead in, then the third. “I’m going to need to give my Queen a special thank you for this. It’s been awhile since I last had my own two hooves on a new guard, and I must say, I missed how intimate it can be.” She drove the sleeve a bead deeper, nearing the last, and largest two.

Cobalt whined as she drew it out again, then slowly plunged down to the very last bead.

“W-what is this for?” he asked.

“Are you not enjoying yourself?” Lavender questioned, her golden eyes flicking up to meet his with a knowing look.

“I-” he let out a squeak as she slowly pressed the last bead against his cock hole “-I’m just curious.”

Lavender chuckled and looked back to the sleeve.

“This sleeve will prevent you from cumming at all, sort of like the null bulge on your proper guard suit.” She drew out all of the beads one last time, then slowly pushed them all back in. “You’ll feel everything, as I’m sure you can tell.”

The last bead stopped against his dick hole, and Cobalt bucked, desperately wanting it to slide inside, to lock his orgasm away. The edging, teasing pleasure was more than he could have ever dreamed, and if it made him a better rubber pony, he was more than willing to lose himself in it. With the pressure from Lavender and his bucking, the bead slid into his cock with a pop.

Lavender grinned wickedly up at him as he let out a cry and continued to squirm.

“Heh, what a horny little bat, so desperate to lock all of his orgasms away.” She massaged the sleeve onto his cock, then around his balls. Once everything was properly sealed away, she took a tube from the crate and applied it all around the sleeve, gluing it in place. “There, all ready to be teased into the perfect slave.” She tapped her chin in thought, then stomped her hoof. “Of course, I almost forgot!”

Cobalt doubted that, especially given how brightly she was smiling, but his thoughts were sent spinning away as the beads in his cock started to vibrate. He cried out and writhed in his bindings. Lavender hummed appreciatively and checked the leather straps, ensuring that he was still locked in place, unable to move.

“Did you like that my little bat? I forgot to mention that the beads vibrate.” She placed a hoof on his cock. “I think a nice medium is perfect for you. Just a constant wave of pleasure, edging you up and up with no release until you’re nice and trained. Not to mention letting me ensure everything is healthy while we work.”

Her words described his thoughts exactly. The pressure had been a foreign, but welcome pleasure, but now that the sleeve was vibrating, it was close to maddening. Arcs of pleasure raced up his body, filling his brain with so much lust that he could barely see clearly. His moaning fell away to mere squeaks as his head slumped forward, his muzzle opened and drooling. He couldn’t think, couldn’t do anything other than be lost in the pleasure. Few things could jarr him from his daze.

Lavender giggled and wiped away the drool running down his chin.

“Well, we can’t let you make a mess of yourself...”

Cobalt was shocked from his stupor and let out an audible gulp as she revealed a massive horsecock gag.

“I… think I need a smaller one,” he managed to whisper.

“Not if you wish to sever the castle royalty,” Nurse Lavender said. “This is a true-to-size recreation of Queen Lunaris’ favored strap-ons, and she loves testing it on the guards, usually publicly. Just remember to breathe through your nose…”

The false cock dripped as she moved closer, and Cobalt gulped again.

“A-are you sure?”

He yelped when her hoof cracked against his flank, this time without the teasing mercy she’d been using earlier. Lavender clicked her tongue and shook her head.

“Second guessing and not addressing your mistress properly? Please don’t disappoint me again Cobalt. Your training is going to be fun, and you’re a natural. That pesky self-doubt is getting in your way, however, and I don’t like it.”

Cobalt winced, more at the mare’s tone than the actual strike to his flank. He hated when ponies were disappointed in him, and maybe that was why he was a sub; he had an inescapable need to please. With how kind she had been so far, it felt doubly so worse that he had let Nurse Lavender down. His ears pinned to the sides of his head and he looked down in shame.

“Sorry, Mistress. I… I’m just nervous is all.”

A hoof touched his chin and brought his eyes up. Lavender met his pitiful gaze with a smile, and she kissed his nose.

“You are a genuine, good pet, and your apology is accepted, my adorable little bat.” Her smile became sly. “There is one condition of course.”

Cobalt felt his heart soar, even as a touch of his nervousness reared its ugly head. He squashed it though, more than eager to please his new mistress.

“Please command me, Mistress. I will obey.”

Lavender smiled and raised the gag.

“Open.”

With one last gulp, Cobalt opened his mouth as wide as he could. Lavender held his lower jaw with one hoof, then slowly pushed the gag in with the other. The lube on the dildo was sweet, and more than did its job, helping the massive silicone cock slide across his tongue and toward the back of his throat. As the fat cockhead stuck at the entrance to his throat, he felt his eyes tear up, and his chest heaved slightly.

Lavender cooed softly and her hoof shifted to stroke his throat.

“Swallow, Cobalt. You can do this.”

Cobalt did as instructed, closing his eyes and doing his best to swallow. In a loud gulp, the clock slid deep into his throat, suddenly cutting off his air supply. He gurgled mildly in alarm, trying not to panic as he looked to Lavender for guidance. She continued to stroke his throat.

“Breath through your nose, Cobalt. You’re doing so well. Just take a nice, deep breath through your nose.”

Cobalt relaxed under her comforting words and did as she instructed, forcefully drawing air in through his nose. He relaxed further as his lungs filled with sweet, rubbery scented air.

“Good slave.” Nurse Lavender slowly pushed the rest of the gag into his throat, then buckled the straps around his head. Her hoof rubbed the bulge in his throat softly, and she smiled. “Now, that was a touch easier than the real thing will be, but I couldn’t tell you that, because you need to learn to automatically trust your master. There’s a numbing agent in the lube, as I’m sure you’ve noticed since you aren’t gagging.”

Cobalt found that he did. There was a comfortable pressure of the cock filling his throat, but no pain, no itches or urges to cough or drive the wonderful thing out. He nodded stiffly, and Lavender giggled, patting his cheek.

“Good slave. You are capable of so much, so trust in your mistress to bring it out. Now!” she chirped, spinning away. “We have two more items, and then your indoctrination can begin in earnest. To start…”

She lifted a section of the padding on the floor beneath his cross to reveal another massive horsecock. She cranked the machine up until the head of the well lubed cock rested against his tail hole. Cobalt’s moan was muffled by the cock in his throat, but Lavender seemed to pick up that he was more eager to try and fit this cock in than he had been with the one plugging his mouth.

“Thought you’d like this one,” she giggled, watching him squirm. “We’ll start on low, then work our way up to a proper speed once you’re properly warmed up.”

Cobalt huffed and nodded, then moaned and once more strained against his restraints as the cock slowly moved forward, its fat head pressing against his anus, forcing it to stretch open. Lavender watched him with a smile, cranking the dial until it was at the lowest setting. The horsecock drove itself slowly upward with mechanical impetuous until it was fully buried in his ass, crushing his prostate with its girth. It then slowly began its long withdrawal. Cobalt cried out as the source of pleasure slowly left his rear, only to moan in pleasure as it was slowly returned. The vibrators in his cock buzzed to life, and he screamed through the dick in his throat, the sound little more than a muffled whimper. He could feel the pressure building in his crotch, spiraling up and up and up toward an orgasm… and then it simply kept going. And going. Cobalt couldn’t escape the towering spiral of pleasure, couldn’t budge his restraints in the slightest. His lust filled eyes locked onto Nurse Lavender, pleading for release.

The purple and red clad nurse kissed his nose and chuckled knowingly.

“No slave, no release. This is what you have in store for the rest of your life here.” She ran a hoof down his panting chest. “You are here to serve, not be served, but I think you know that, and I know you love it.” Her hoof traced the head of his cock, then slowly slid down his shaft, fondling his rubber-covered balls. “You want exactly what I’m about to do to you, and you can’t wait to be so well trained that you only cum when somebody else wants you to.” Her golden eyes caught his and her fangs glinted as she stuck her tongue out, slowly dragging it up his cock. “You want to be nothing more than a cute little rubber pony, protecting and playing with all the rest, always craving for the day some stallion or mare drags you away to have their way with you.”

Cobalt felt no hesitation as he bobbed his head, moaning as the cock in his ass bottomed out once more. Lavender chuckled.

“Good slave. That leaves only one thing to start your training.” She held up a fully enclosed helmet with a black visor. “This will close you off from everything and will force you to watch the screen where all your duties, every command your queen may give will be installed in your pretty little head.” She purred. “There’s also a few little loops in there to make you crave being more submissive, to make you burn with your love of being covered in rubber from head to hoof.” She raised his chin and opened the bottom of the helmet. “Now, I remember you mentioning something about wanting to be hypnotized?”

Looking at the helmet, Cobalt could already see a spiral with words flicking across it. This was it. There would be no turning back from this. That very fact sent a jolt of excitement through his body. He gave the nurse a nod, ready for his new life to begin.

“Goodbye Cobalt Flash,” Nurse Lavender said, lowering the helmet onto his head “When you’re done, you will be Cobalt of the Royal Guard.”

Cobalt felt the helmet lock onto his collar, then felt latex flow from the helmet to surround his face, sealing everything besides his nose and eyes underneath a mask of rubber. Latex flowed into his ears, and he heard a faint whisper that quickly grew into a constant, soothing voice. It told him what his name was, what his purpose was. Though it was unintelligible to his conscious mind, hidden under the primary voice were layers of softer voices telling his subconscious to sink, to feel his love for latex and servitude deepen as his arousal rose. Cut off from the outside world, the voices brought into focus every little thrust and vibration that only served to drive him wild with lust.

“Hello pet,” the primary voice said. “You’re here today because you want to live in latex. You want to be a rubber slave, is that right?”

Cobalt moaned in reply, his eyes compelled to remain open and staring at the pretty twirling lights before him. The voice giggled, as if it knew his answer.

“Good slave. Feel the latex on your body, feel the pleasure streaming through every little nerve. Remember who gave you this wonderful pleasure.” Words flashed in the spiral, and the voice echoed them. “Your queen gave you this pleasure. You serve Queen Lunaris, and you are going to be one of her rubber guards. Doesn’t that sound wonderful? Wrapped in rubber, bound to serve the most beautiful queen of latex? Say it slave. Say you want to serve your queen.”

I want to serve my queen, Cobalt’s thoughts automatically replied. He jerked as the cock beneath him plunged faster and deeper into his ass, as if to reward his answer.

The voice giggled again.

“Good slave, now repeat after me. You are a member of your queen’s rubber guard, and you love it.”

His eyes could do nothing but stare forward at the spiral, and he began a long, continuous moan as his mind repeated the words automatically again. Even if he wanted to, there was no escape, nothing for him but endless mind-numbing pleasure, all encompassing rubber, and the spiral that slowly installed his new purpose.
