Sunburst hummed cheerfully to himself, as he trotted through the Crystal Empire. With his cape flipping behind him, he navigated the narrow back alleys and service roads to his destination. Stopping for a moment, and retrieving a paper clipping from between his lips, he checked the street names of the intersection he stood at. Sunburst had never been all that acquainted with the industrial district; but he’d had the forethought to study a map, prior to leaving his home. He just hoped he wasn’t walking face first into some sort of scam.

A few days ago, while browsing the paper, Sunburst stumbled across a rather curious advertisement. The piece mentioned a “New and Innovative” way to help stallions with their love life. More interesting still was the fact that the first twenty studs would get a free week-long stay at their transformative clinic and, if somepony wasn’t pleased with the results, they’d be compensated two hundred bits for their time. Considering his love life was nonexistent, and after conferring with Princess Cadence, the crystaller had decided to give it a shot. After all, even if this miracle treatment didn’t work, he’d walk away with a substantial stack of bits.

The stallion adjusted his glasses and double checked the address on the clipping. The building certainly didn’t look like any sort of therapeutic facility that Sunburst had ever seen. Occupying nearly half of a city block, the structure was, like many others in the crystal empire, constructed of a gem-like material. If he had to guess, there were at least three stories inside, leaving him to wonder exactly what awaited him. There was but a single door and, interestingly enough, no windows to speak of. With a shrug, he trotted up to the entrance and swung open the heavy entryway.

Stepping inside, Sunburst was greeted by a fairly spartan lobby. Another door sat on the opposite wall, and a handful of chairs lined either side of the small space, but that was about it. Surveying the interior, he started, as a voice called out.

“Name please,” a non-distinct voice announced, seemingly from nowhere.

“Sunburst. I…I found this coupon and thought I’d give it a shot,” the unicorn commented, wheeling around and looking for a source of the noise. After a moment, he noticed a small slotted grate located beside the interior doorway. “So, I guess I’m one of the first one’s huh?” he chuckled, hoping he would be able to claim the free treatment.

“Insert the coupon in the slot, then proceed inside,” the voice instructed.

With a nod, Sunburst slid the paper through the opening. Almost immediately, the doorway clicked, likely unlocked by some magical mechanism. Peeking his head in, he hesitated. The next room was dark, nearly too dark to see inside, but it looked bare. Steeling his resolve, he stepped inside, igniting his horn to illuminate the area. As the door closed behind him, a set of lights in the ceiling illuminated.

“Disrobe, please,” the familiar voice prompted.

Taking stock of his surroundings, Sunburst found the room utterly bereft of anything at all, save a large mirror inset within one wall. “Why? All I have is my cape,” he grumbled, irritatedly fidgeting with his glasses. It wasn’t that he had a problem with taking his cape off, but it always made him feel more comfortable.

“Biostatistical data is required for optimal training. Disrobe, please,” the cold voice responded.

“Oh, I think I’ve heard about those! Aren’t doctors in Manehatten doing a study on pegasi bone density, and muscle mass, compared to earth ponies?” Sunburst yammered, unclasping his cloak. With nothing to set it on, he carefully folded the garment and held it in his hoof. “Alright, now what?” he asked, looking about expectantly.

“Sunburst. Species, unicorn. Biometry recorded. Increased perspiration and heart rate detected. Countermeasures will be administered. Any effects will be laundered and returned, after you have completed your stay. Please, proceed to room number three,” the voice explained, as the interior door swung open.

Setting his cape down, Sunburst peered into the building’s interior. A long well-lit hallway led deeper into the structure; along its sides sat doors, ten per side, and a stairwell was situated at the end of the corridor. His curiosity overrode his anxiety, while he slowly trotted to the designed room. As he’d expected, each of the rooms was numbered. Somewhat disconcertingly, he realized that there was no apparent way to open the doors, since they had no handles or any noticeable mechanisms. Approaching the third room, the blank slab of opaque crystal opened automatically.

Poking his head inside, Sunburst found the chamber remarkably quaint. It was, as far as he could tell, a full fledged apartment. Seeing himself in, he inspected the area and was pleasantly surprised. The studio suite had all the amenities of a small condo, including a few books and a radio! Browsing the literature, he realized they all seemed to be written for mares; considering the subject matter ranged from fashion to how to pleasure a stallion. He shrugged, content that he’d have something to read while he relaxed. He jumped and spun around, as the same neutral voice from before spoke out.

“Subject Sunburst, there are garments in the dresser. Due to your elevated levels of stress, at removing your cloak, please feel free to don any of the apparel available,” the radio advised. “Your afternoon relaxation session will commence shortly. In the meantime, please make yourself comfortable,” it concluded, disappearing into a soft, melodic tune.

A bit perplexed, Sunburst moved to the dresser and opened a drawer. A number of outfits and accessories lay neatly arrayed within, although something was off; everything there was for mares. Panties, negligee, skirts, leggings, and even a few rather salacious articles with words like “Slut” or “Princess” printed on them. They must have accidentally given him the wrong room, but it wasn’t that big of a deal. It was a free trip, so he could live with the small mixup. Spying a quartet of striped knee socks, Sunburst levitated them to himself. Marked with horizontal stripes of blue and black, very closely matching the cyan of his eyes, he decided to try them on. After magically pulling them up his front legs, he moved the remaining two to his hind quarters. Hauling them over his thighs, he felt the fabric gently dig into the supple meat of his upper legs.

Content with his choice of comfy leg wear, Sunburst lounged on the bed. He wasn’t sure how long he had until his relaxation session, so he figured he’d kill some time with a book. Hovering the a fashion magazine over, he sorcerously flipped to the index, looking for any articles of interest. Settling on a piece about seductive nightwear, he engrossed himself. Even though he’d assumed it would be a boring read, it was actually rather intriguing. It detailed ways to accentuate the natural contours of a body, slimming effects of various colors or patterns, and subtle ways to tease stallions. Despite himself, he started getting a little worked up; that was, until the music from the radio stopped.

“Subject Sunburst, please proceed upstairs to room two. Further instructions will follow, upon your arrival. Before you depart, please fill out a meal ticket on the nightstand,” the radio directed, immediately switching back to the soft tune, after finishing its message.

Glancing over at the nightstand, Sunburst noticed there was a menu, along with a pen, resting beneath the bedside lamp. There were a number of simple meals available, as well as a breakfast menu for the following morning. Marking down his choices, a lush salad with strawberry tart for dinner and potato hash perspectively, he trotted out the door and towards the stairwell.

Making his way upstairs, and still not having seen a single soul, Sunburst discovered the second floor was very similar to the first. A long hallway led towards the front of the building, with several rooms along either side. Marching along, to the aptly marked second chamber, the crystalline doorway slid open. To his utter befuddlement, the spacious interior was almost empty, save for three padded islands that stood just under waist level. Interestingly, all four walls of the room were covered in mirrors, almost as if the area had once been part of an exercise facility.

“Select an unoccupied device and stand above it,” the now familiar voice intoned, urging him forward.

Straightening his glasses, and with all three of the constructs bare, Sunburst chose the nearest. Stepping over it, he patiently waited for something to happen. It wasn’t like any machine or furniture he’d ever seen. Craning his neck downward, he inspected the padded surfaces of the rhombohedron. Suddenly, and quite unexpectedly, a hatch appeared beneath his groin; but, before he could ask a question, the mysterious voice answered for him.

“Stallions with too much sexual tension tend to come off as awkward with mares. As such, this tool will allow you to relax and relieve some of your anxiety. Please, enjoy yourself,” it explained, as a cylindrical appendage pressed against the stallion’s sheath.

“Well then, that’s kind of nifty,” Sunburst thought aloud, smiling sheepishly, as the contraption deftly bumped against his hidden stallionhood. He wasn’t sure how much he’d be able to enjoy himself with it, but he was certainly curious. Concentrating on the article he’d been browsing in his room, his tool began to limply hang beneath him.

He yelped, as the gizmo locked around his semi-flaccid shaft. “Hey, what the...Mmm…” he hummed feeling the machine apply lubricants to his tool, while it gently massaged his length. Almost reflexively, he bucked his hips, jamming a few inches of himself deeper into the chamber of the mechanism.

“Phase one complete. Beginning second phase,” the voice boomed. A second compartment on the apparatus opened, as a coiled arm crept forth. While the stallion was blissfully unaware of the tendril’s appearance, too preoccupied with thrusting into the toy, the tentacle crept between his thighs, and to his rear. A gobbet of purple goo oozed from the tip of the vine-like limb, just moments prior to it prodding into his backdoor.

With an excited squeak, Sunburst nearly toppled over. Frantically, he looked around, but he couldn’t see much. Considering his stallionhood was firmly entombed within the machine, he didn’t want to risk wheeling around. The sensation of something toying with his pucker disappeared, as it penetrated him. He gasped, caught woefully unprepared for the sensation. It didn’t hurt, surprisingly, but it sure as heck had caught him off guard. Whatever it was, it was warm and didn’t feel all that large. Fortunately, it had lubricated him enough to allow easy access to his tush.

“Milking of the prostate gland has been scientifically proven to produce orgasms with a minimum of eighteen point five percent higher endorphin levels and increased sensations of euphoria. The lubricant is a carefully crafted mixture of changeling venom, light anesthetics, and vasodilators. Please, enjoy yourself,” the voice casually commented.

The sensation of tentacle plumbing his interior, while odd, wasn’t all that bad; that was, until is hit a particular spot a few inches inside of him. A wave of pleasure radiated through his abdomen, causing a potent gout of pre-cum to spurt from his member. He’d read about prostate stimulation, though he’d never had the gumption to try it himself. Slowly, he started to move again, however it wasn’t the same as before. Instead of bucking his hips down and into the device, he rocked his waist back towards the tendril in his rear.

In a matter of moments, Sunburst was panting heavily, as the flexible arm of the apparatus continued to milk his P-spot. Finally, with a pitiable moan, he came, bathing the interior of the machine with his spunk. He sighed, as he felt the tendril slink from his behind. Acting quickly, he spun around to take a look at it, before it disappeared from wherever it had come from. Long and sinuous, it almost looked like some sort of plant; which, for all he knew, it may have been. With its job completed, the mechanism’s segments retracted, leaving the stallion to huff over the now non-descript object.

“Please, return to your room and, if you so choose, shower. Your meal is now waiting for you,” the voice boomed, opening the doorway and allowing him to exit.

Plodding back to his room, Sunburst couldn’t help but feel dirty. The twin cheeks of his ass glided between each other, aided by the residual lube which had been used on him. What would somepony think if they saw him like this? Clad in socks, cum leaking from his sheath, his rump slathered in goo. The notion, while silly, made him blush. Still, he had to admit, the experience had been pleasantly surprising. Traversing the stairwell, and trotting through the hallway, Sunburst quickly found himself back in secluded confines of his suite. As his host had promised, his meal sat on a platter atop his bed. But, as delectable as it looked, he needed to clean up first.

Tugging off his socks, and casting them to the corner, the stallion entered the bathroom. Much like the bedroom, it was well furnished, with a large shower/bath combo, sink, and standing mirror. Setting the water to warm, Sunburst glanced at his reflection. As per the usual, his mane was rather scraggly, and his goatee somewhat frayed. His eyesight wandered over his frame, down his neck and past his torso, ultimately settling upon his cutie mark emblazoned posterior.

Even as a colt, he’d always had a somewhat generous posterior, of which his mother was always quick to point out. Slowly, he turned, presenting his backside to the reflective surface. Gazing at his rear, one forehoof crept back to his cheeks. Pulling upon the succulent orange glute, Sunburst’s pace quickened, as he gazed upon his lube slickened pucker. Shaking his head, attempting to dispel any raunchy thoughts, he frustratedly hopped into the steaming shower.

What was wrong with him? First, he’d shamelessly enjoyed the toyings of the strange contraption; now, he couldn’t keep himself from thinking about just how good it felt! On a physical level, it made sense. It wasn’t like he’d ever given much attention to his sexual urges, often times going for extended periods of time without any type of climactic release. While he did feel a little guilty for relishing the experience, he wouldn’t mind having another go at it. In short order, he completed his shower and dried off.

Sauntering back into his room, Sunburst absentmindedly picked up the book entitled How to Please Your Stallion. With such a meager selection of documents, it would have to suffice. Plopping down on the bed, he dug into his meal, while browsing the text. He figured it may give him some insight into how mare’s function, if nothing else. Contenting himself with his evening of solitude, the unicorn drifted off to sleep, while listening to the soft and melodic tunes from the radio.

“Good morning, subject Sunburst. After your meal, please dress yourself and proceed to room two,” the voice rang out, shaking the unicorn from his slumber.

Dreamily, Sunburst rolled from the bed. The breakfast hash he’d ordered waited just inside the door, steaming invitingly. He’d never been one for mornings, often forgoing anything to eat until mid-day. Levitating the tray to himself, he munched away at the crispy and cheesy vegetable dish, as he reflected on a particularly odd dream he’d had.

He’d been in a room, surrounded by large, muscular stallions. They’d catcalled him, complimenting how sexy he was, while they promised him all manner of sinful delights. In a bizarre twist of fate, he’d spun around to face them, and found himself looking at a mirror. To his utter disbelief, he’d been dolled up like a mare, replete with makeup, a short skirt, and a styled mane. The fact that he was in drag wasn’t what was alarming; no, his inner conflict was because he’d found the whole situation maddeningly hot.

Grumbling to himself, and having mechanically dispatched his breakfast, Sunburst trotted into the dresser. Gathering up another quartet of socks, soft pink with a smattering of artistic designs, he readied himself for another session upstairs. For whatever reason, he was having a hard time concentrating on anything but another bout with the machine. He told himself it was because he wanted to note the finer nuances of the physical sensations it elicited, but in the back of his mind he knew it was more than that. Scampering into the hallway, and towards the stairs, he proceeded to his destination.

As Sunburst made it to the top floor, and encroached on the second room, he paused. He could swear he heard a soft moan from inside. Approaching the doorway, and allowing the portal to open, he peeked within. To his shock, a cream colored pegasus stallion stood atop one of the devices, thrusting away, while his backside was plundered by the contraption’s tentacle. Before he could move, the pony noticed him.

“Hey, it’s about time somepony else joined me,” he called out. “The name’s Mmmnn Candlelight,” the stallion greeted, as the machine worked his body.

“I’m Sunburst. P...pleasure to meet you,” Sunburst stammered, feeling his pulse quicken, at the sight. His stallionhood slipped from its sheath, while his eyes unwaveringly sat upon the pegasus.

“Go ahead and...Oh fuck...join me!” Candlelight goaded, nodding towards the empty machine beside himself.

“A...alright,” Sunburst stuttered, fretfully. Nonchalantly chatting with the stallion, while being lewdly serviced, left him feeling conflicted. Were it not for how casual Candlelight had been, he’d have immediately fled; at least, that’s what he told himself. In truth, he was more than a little jealous; not only for the sensation of the mechanism’s touch to return, but because he’d was turned on by the sight of the cute stallion getting off.

Moving to the next closest machine, Sunburst quickly straddled the thing. The compartment directly beneath him opened, allowing the arm with the milking tool to slip over his rapidly hardening length. He stood there, unmoving, as the device worked his tool; all the while slipping glances at Candlelight.

“Aren’t these...Mmmph...things great?” Candlelight huffed, turning to address the unicorn next to him.

“Yeah, if they’ll work right,” Sunburst murmured, keenly aware that there was no tentacle toying with his rump.

“Kind of a bottom, eh?” Candle asked, cocking an eyebrow.

“What? No! It’s just…” Sunburst trailed off, unsure of what to say. He had thoroughly enjoyed having his ass played with, so maybe he was. Realistically, he was woefully inexperienced in any form of carnal art, so he was left doubting himself.

“How about I give you a helping hoof,” Candlelight began, carefully removing himself from the device. As soon as he started to move, the machine started shutting down, retracting it’s various portions into its main housing.

“W...wha…” Sunburst mumbled, watching the stallion walk behind him. A startled squeak escaped him, as the pegasus’ muzzle pressed into his tush. He moaned, feeling the stallion’s tongue lapping at his pucker. Although the device was still rhythmically pumping his shaft, the sensation was an afterthought, compared to Candle’s rimjob.

Closing his eyes, Sunburst enjoyed the affectionate and sloppy oral; that was, until it abruptly stopped. A heavy weight impacted upon his hindquarter, and the stallion’s forelegs wrapped around waist, as he was mounted. He could have moved, he could have told Candle to stop, but he didn’t. Reluctantly, he pressed back, urging the pony to continue.

“Oh ho! So you are a bottom. Well, in that case, how about you beg for it?” Candle chuckled, teasing the unicorn’s pucker with the tip of his tool.

“P...please?” Sunburst whined, his blush deepening. He couldn’t believe what he was saying.

“That didn’t sound very convincing,” Candle snickered, slowly applying more pressure to Sunburst’s backdoor.

“Please rut meeeeeee!” Sunburst’s request jumped a few octaves, as the stallion penetrated him. The moment was surreal, worlds beyond the event from the day prior. He never knew his ass was so sensitive, it was like he could feel every vein and ridge along Candle’s length. While the other pony wasn’t the most well hung stallion he’d ever seen, he was still nearly double the girth of the sinuous vine-like appendage of the mechanism. Every inch of Candle’s shaft ground into him, until the pegasus had bottomed out. He could scarcely believe it, but the sensation was divine.

Without a word, Candle pulled his hips back, steadily retracting his tool from Sunbrust’s hole. As he did, the orange unicorn beneath him fidgeted and clenched around his length. “Oh ho! Thirsty, eh?” he chuckled, leaving just the blunt head of his prick within his partner’s pucker.

Sunburst nodded, and his blush deepened. Abruptly, the pegasus rammed himself home, hilting himself in one smooth movement. He stifled a moan, as Candle began rhythmically plowing his ass. It was leagues beyond what the sex toy could afford; the warmth, feeling the pony’s hot breath on the nape of his neck, having his hips firmly held by his partner, it was all simply wonderful. Slowly, he rocked himself back, synchronizing his movements with his partner’s.

“You know...Unf...you’d be even cuter, if you shaved that goatee of yours,” Candle whispered, while he steadily pounded away.

Although Sunburst heard the words, he was unable to reply. Being fucked and having his stallionhood milked by the device under him was proving to be quite the combination. Steadily, a strange sensation began to overwhelm him. It wasn’t like the normal telltale signs of an orgasm; no, this was something entirely different. A sublime pressure was mounting in his lower abdomen, radiating a heat throughout his entire body. Feverishly, he pressed back against the pegasus’ thrusting hips, clamping down with Candle’s backstrokes and relaxing his pucker with every plunge.

“Not sure...Nnngh....how much longer I’m gonna last. W...Mmmph...where do you want it?” Candle grunted, his pace quickening by the second.

“C...cum in me!” Sunburst unabashedly whimpered, looking over his withers at the cute pegasus who’d mounted him. It felt like he was going to go insane, like he was going to explode. With every plunge, his partner’s balls slapped against his own, only heightening his arousal. His thighs trembled, and his ass rippled with each impact. Just when he thought he couldn’t handle any more, Candle hilted him fully.

His eyes flew open, as a wave of superb warmth crashed against his insides. Impulsively, Sunburst screamed in orgasmic bliss, climaxing nearly in tandem with his partner. Saliva crept down his chin, dripping to the floor below, as he was rocked by the most powerful fit of ecstasy he’d ever experienced. His frame shivered, and his legs gave out, causing him to crash atop the machine.

“Sweet Celestia, I’m usually a bottom; but, I gotta admit, you are one hell of a lay!” Candle wheezed, affectionately kissing the unicorn’s neck.

Sunburst nodded, cum drunk beyond all comprehension. To say the experience had given him a new perspective would be an understatement. Slowly, Candle eased himself off, dragging his tool from Sunburst’s ass. A part of him lamented the departure, yearning to feel the exquisite heat his partner’s cock had afforded. As the pegasus pulled out, he felt a dribble of seed leak from his battered hole; he clenched down, instinctively yearning to trap as much of it inside as possible.

“Kind of a shame that today’s my last day,” Candle grumbled, trotting around to face the insensate unicorn. “Tell you what, once your stay is done, look me up. I know a place where the stallions are packing way more than what I got,” he added, giving Sunburst a wink. “Anyways, it was nice meeting you,” Candle concluded, as he trotted towards the door.

All Sunburst could to was watch the stallion leave. After a minute, and realizing he was an abject mess, he unsteadily got to his hooves. Hobbling out the door, and down the hallway, he eventually made it back to the confines of his room. To think, he’d gone through his entire life without considering the possibility of hooking up with a stallion. It seemed rather silly, especially because he was around so many on a regular basis. Heck, he had to know at least a dozen guard stallions in the castle, and that wasn’t even counting the stallions he was familiar with in the crystal empire.

Just as he tugged off one sock, he heard the door open behind him. Confused and surprised, he looked over, wondering who’d interrupted him. He was an abject mess, sweaty and with an ass full of spunk, so he was in no shape to deal with a visitor. Thankfully, it was only Candle.

“Hey, before I go…” the pegasus cooed. Stepping inside, he set down his saddle bag, and made bee-line to Sunburst. Trotting up to the unicorn, as cool as a cucumber, he guided Sunburst to the bed.

“What are you…” Sunburst began, perplexed, while he was seated on the mattress. With his hind legs hanging over the side, Candle inspected his groin. The attention, while unexpected, caused his stallionhood to peek out. Looking between his equipment, and the pegasus’ face, he gulped.

Upon spying Sunburst’s emerging tool, Candle’s head shot forward. Like a striking viper, he wrapped his lips around the blunt head, savoring the salty taste of cum. He’d always had a weakness for sucking cock, and he’d be remiss for not sampling the orange stallion’s flavor. He didn’t expect a full load, nor did he want one, but a taste certainly wouldn’t hurt.

Watching Candle fellate his hardening tool left Sunburst at a loss for words. Truthfully, he’d never had anypony suck his dick, let alone a stallion. Still, he had to confess, the sight was pretty hot. Just as he was getting into it, with his length rising to full mast, Candle stopped. Before he could say anything, his partner spoke.

“Consider that a friendly reminder to look me up,” Candle purred, licking his lips. Leaving a stallion worked up almost always ensured a future hookup, so he was content with that. Gathering up his bag, he waved goodbye, but not before shooting Sunburst a kiss.

Confounded by the abrupt oral, and frustrated with the lack of finish, Sunburst groaned. Yeah, considering the whirlwind of recent events, he was pretty sure he was into stallions. Like, really into stallions. Sure, it could just be from lack of experience, although he’d never found himself this lusty with mares. Resigning himself to wash up, before the jizz in his fur could dry, he trotted off to the bathroom.

In a numb stupor, he showered, cleaning the cum from his fur, before flopping on his bed. While the experiences he’d had were exceedingly enjoyable, he was left rather tuckered out. Although it was still relatively early, he decided to take a brief nap. Sunburst swaddled himself in a blanket, he quickly fell asleep. As he drifted off, his thoughts were filled with all manner of provocative imaginings and fantasies, all of which involved well hung stallions.

While he hadn’t expected to take anything more than a cat nap, Sunburst awoke several hours later. Wiping the grogginess from his eyes, he spied his lunch entree just inside the door, presumably having been delivered some time ago. Since he wasn’t all that hungry, he set it on the nightstand to wait. As with the night before, he was keenly aware of a particular dream he’d had.

He’d been dressed in a skirt, leggings, and a pair of panties, all while he’d been servicing a pair of hulking stallions. Situated between them, one slapping his face with their cock, the other toying with his behind, he’d begged them to breed him. As outrageous as it was, he couldn’t shake the images from his mind leaving him with a feeling of frustration and longing.

Moving into the restroom, and splashing some water on his face, Sunburst paused. Candle’s words rang in his ears, specifically about how he’d be cuter without his signature goatee. Looking below the sink, he found a number of hygiene supplies, including a razor and shaving cream. Levitating the objects to himself, he shrugged.

“Well, Sunburst, if you don’t like it, it can always grow back,” he mused, lathering his chin. With expert precision, he removed the offending lock of hair from his mug, leaving an even coat of fur over his countenance. Inspecting himself, he had to admit, the lack of facial hair did leave him looking slightly more effeminate and coltish.

With a newfound confidence, Sunburst trotted back into his room and to the dresser. Pulling open the drawer he picked out a skirt, leggings, and panties; while they weren’t the same as the ones he’d worn in the dream, they were similar in design. To complete the outfit, he selected a dark blue collar and a seafoam colored ribbon to tie around his dock. Hastily, he donned them, leaving him looking like some scandalous cocktail maid. His stallionhood, nestled within the confines of his negligee, bulged obscenely below the hem of his skirt. He jumped, as the mysterious voice shook him from his reverie.

“Subject Sunburst, please proceed to room two. We apologize for the inconvenience this morning,” it announced, before cutting out and being replaced by the continual soft tunes of the radio he’d grown accustomed to over the past few days.

A smile crept across Sunbust’s face. That’s right, the machine had been malfunctioning, so they must have been trying to make up for it. Eagerly, he dashed out the door and toward the stairs. Dressed like a mare or not, he wasn’t going to let another session slip through his hooves. As soon as he got to speak with somepony, he’d have to ask where they acquired the odd devices, since he wouldn’t mind owning one himself. In a matter of seconds, he’d made his way back upstairs and to the familiar room. Bolting through the door, he proceeded to the first contraption, enthusiastically straddling it and awaiting his treatment.

As expected, the compartments on the device slid open, allowing the tendril and milking cylinder to move to his groin and rump, but there was a problem. Trapped within his panties, the suctioning portion of the mechanism was unable to grasp his stallionhood; so, after a few failed nudges at his groin, it grew dorment. Truth be told, he was far less concerned with the massaging of his shaft than in previous sessions, instead more focused on having his backside once again toyed with.The tentacle, however, slipped past his negligee and into his pucker. As good as it felt, it was nowhere near as enjoyable, or large, as Candle’s cock had been.

“Darn it, I wish this thing was bigger,” he sighed, scrunching his snout in consternation.

“Please select stimulation level,” the voice boomed.

“Uh…” Sunburst hummed, glancing around the vacant room. “How many levels are there?” he asked, feeling a bit silly for talking to the seemingly omnipresent observer.

“There are a maximum of ten levels, of which you previously used the first. Please select stimulation level,” it explained coldly.

“Hmmm,” Sunburst hummed, rubbing his newly shaven chin, “how about level seven.” After having handled a fully grown stallion, which he figured had to be at least a four or five, he wanted to up the ante. Even if it became too much to bear, he could always hop off the thing.

His request was met with immediate action, as the milking appendage retracted. The vine-like arm withdrew from his rump, but pulled his panties aside. He cocked an eyebrow, as the contraption beneath him vibrated slightly, and a compartment at the fore slid open. To his astonishment, a large mechanical arm appeared, weilding a simulacrum of a stallionhood on a piston. The fact that a dildo was hovering in front of him wasn’t what was concerning, it was the size of the thing that made him nervous. It had to be nearly twice the size of Candle’s flesh and blood dick, and looked like it’d been crafted in painful detail; veins traced its length, from thick root to bloated tip, and it even had a sculpted pair of balls beneath its base. Glancing back, a similar arm was positioning itself at his rump, lining itself up with his ass.

Sunburst gulped, realizing he may have made a miscalculation. “Maybe we can go to level Mmmph…” he gagged, as the dong in front of him thrust into his open maw. As if that wasn’t disconcerting enough, the sensation of the rearward one prodding against his pucker made him shudder. Mercifully, both of the dildos appeared to be exuding the same lubricating fluid which the tentacle had used, as his mouth was soon filled with a cloying and sweet viscous substance, and his cheeks were smeared with a cool gooey fluid.

The dong at his rear did much the same. Seating itself against his hole, its tip gushed the slick fluid against, and into, his ass. Considering how extensively his rump had been used, in the last day or so, it yielded little resistance to the fluid. The feeling of having what felt like a pint of fluid injected into his backside was odd, yet not unpleasant. Just as he was getting used to it, the flow ceased and the toy started pushing against him.

As the pressure on his backdoor increased, Sunburst tried to relax himself. Harder and harder it pressed, until he thought he couldn’t bear it anymore. Then, with a resounding pop, it entered him, burying nearly a third of itself within his tush . He would have gasped, were it not for the dong filling his muzzle. As stretched as his ass was, the dildo continued its inexorable drive forward with glacial speed. Mercifully, the device slowed, when the thick medial ring bumped against his pucker; but it was undeterred. With mechanical impetus, it continued, pressing deeper and grinding against his prostate with cold, calculating force. It wasn’t until he felt the hefty, sculpted balls rest against his own that it stopped.

Sunburst was only given a second to relax, as the synthetic dick in his ass began its retreat, partially freeing itself from his rump, only to slam itself back forward. In spite of its size, and his relative discomfort, a droplet of pre-cum dribbled from his stallionhood. It didn’t hurt, per se, but he was being pushed to its very limits, and that wasn’t even taking into account the toy he was fellating. Sunburst’s eyes darted around wildly, as his body was ravaged from both ends, until they settled upon his reflection. There he was, done up like a mare, being spitroasted by two titanic sex toys. Everywhere he looked, the mirrors forced him to see exactly what he was doing.

Finding himself with few other options, he closed his eyes, envisioning his dream from the hour prior. A stallion at his front, filling his gullet, while another plundered his rear. Before he knew it, his tongue was gliding over the toy in his maw, as he hungrily sucked upon its shaft. With the dildo pistoning his ass, each stroke brutalizing his P-spot, he whimpered. Meekly, he braced his hind legs, raising his waist and urging the machine to continue.

Seemingly in response to the act, the device increased its speed. Feeling the dildo in his mouth bump against the back of his throat, Sunburst took a deep breath through his nose. Relaxing his airway, he snaked his head forward, allowing the toy to slip into his esophagus. Taking breaths with each of its backstrokes, his lips clung to the artificial shaft , smearing it with saliva and the lube it continued to dispense. Adrift in his thoughts and sinful actions, he dreamt of how it would feel with two actual stallions. Hearing their silken words, feeling their hooves on his flesh, their warmth, their musk, their weight upon him, every facet of the fantasy spurred him closer to the edge.

Gradually, the pressure in his abdomen started to return. Moaning whorishly around the length of toy in his maw, he pressed back at the dildo in his ass. Suddenly, the rearward dong shifted position, elevating itself to more efficiently pummel his most sensitive area. His eyes rolled to the back of his head, as another jet of pre-cum burst from his achingly stiff stallionhood. After settling in its new location, the mechanized cock’s speed nearly doubled.

With his tush now being jackhammered, Sunburst gagged and groaned past the toy in his throat. Just when he thought the machine had given it everything it had, he felt the false cocks begin to pulsate. Rocking back like a filly on prom night, he yearned for more, silently begging the contraption to use him. Without warning, both of the dildos erupted, gushing wave after wave of something hot and sticky into him.

It felt like a tsunami of cum was unleashed within him. His tummy gurgled, while he hungrily gulped down the sticky stuff in his mouth, but that wasn’t the best part. No, his behind was getting the same treatment, as the toy in his ass hosed down his insides with even more of the warm lube. He swore he could feel his gut distending, swelling with the twin loads being deposited within him. The pressure, the sublime heat of it filling his insides, was far too much to bear.

Sunburst came instantaneously, his cock spurting spunk over the machine and smearing his groin. His bulging, strained underwear darkened with his load, wetness spreading throughout the snug garment until it outright spilled around his thighs. Gulping down what he could, a few errant strands of the substance escaped his lips to slink down his chin. Whatever it was, there was a lot of is, because he could feel his belly bloat and sag with its weight. With its job accomplished, the device ceased its movements, retracting from his maw and ass to return from whence they came.

“Please return to your room and, if you so choose, shower. Your next relaxation session is scheduled for four hours from now. Again, we apologize for this morning’s inconvenience,” the voice chimed, leaving Sunburst atop the machine.

Panting, and slathered in his own cum, sweat, and lubricant, Sunburst lay insensate. For the third time in the past twenty four hours, his ecstasy had been pushed to its very limit. He wasn’t sure how long he stayed atop the device, adrift in a sea of depraved bliss, but he eventually attempted to stand. Shakily, he shambled to the exit, his panties barely concealing the abused and supremely tender pucker between his cheeks. As he shuffled back to his room, he couldn’t help but wonder what level eight of the machine would do...
