A Slave for Love

The tiny town of Little Whinny outside of Coltlumbus was definitely not Canterlot, and was doubly not the location of Princess Cadance and Shining Armor’s royal wedding which was due to take place in a few months.

But it was a town with ponies, ponies who had friends and families… and were ripe with love to be fed on.

If you were the kind of changeling to take advantage of that.

In their tiny outpost, Pharynx dragged more pine branches across, trying to hide them from view. Thorax sat despondently on the floor, dragging his hoof across the snow.

“Move!” Pharynx barked, and Thorax scrambled out of the way.

“Pfah-!” Pharynx spat the branch out, looking his little brother up and down, scowling.

“You don’t look good,” he said, in a tone that could almost be mistaken for concerned.

“Oh, well,” Thorax tried to force a smile. “I’m just… tired!”

Pharynx crept closer, and Thorax felt his heart jump into his throat as his brother’s slitted purple eyes scanned his face carefully.

“...Have you not been feeding again?”

Thorax’s lip quivered, and then he pouted, nodding his head sullenly. He just felt so bad for the poor ponies!

“I, I’m sorry Pharynx, it’s just, I feel so bad for them!” Thorax said, buzzing his wings frantically. “I don’t want to hurt anypo- anybody else.”

Pharynx looked beyond irritated as Thorax continued, worriedly.

“Those ponies have families! And now they’re trapped in the hive while we pretend to be them to steal their love!” Thorax’s buzzing reached a high pitch as tears filled his eyes. “I, I hate it.”

Pharynx looked at him for several long seconds and then sighed.

“Thorax, what we do is necessary. We’ll die without stealing ponies’ love, you know that,” he said, rolling his eyes. “You’re still too much of a bleeding heart. It’s not natural for a changeling to feel this way about their food.”

“They’re not FOOD, Pharynx! They’re living-”

“Shut up,” Pharynx ordered, and, blushing, Thorax closed his mouth.

“You need to feed. You can’t be any use to the hive if you’re this weak - not that you’re normally any use,” Pharynx continued. “And if you lose control because you refuse to feed, you could seriously hurt a pony, sucking all their love out at once. Or worse - expose yourself, and the hive.”

From his tone, it was clear Pharynx considered the latter the bigger issue. He glared at Thorax for several seconds, and then his expression softened.

“Listen,” he murmured, stepping forwards. “Why don’t I… take your mind off it?”

He began planting kisses along the underside of Thorax’s throat, making him gasp, caught off guard, a surge of love pulsing out of him that he quickly tried to cram back down, whimpering.

“Pharynx, we, we shouldn’t,” he said, anxiously, even while he could feel his body preparing for the inevitable rutting. “The patrol is going to come by here sometime tonight… We could get caught!”

“So what?” Pharynx challenged. “Then everybody could see what a good, obedient slut my little brother is.”

Thorax let out a moan as Pharynx’s tongue ran up along his jawline, licking the love that rolled off of him like melting icecream, savoring his brother’s sweetness on his tongue. Hearing the moan, Pharynx paused, stepping back.

“Let’s try a little game, brother. I’ll be a pony - you have to drink my love.”

“But, but-”

“I’m giving it to you, willingly,” Pharynx said, smirking. “You aren’t telling me you have some ridiculous morals against that, are you?”

“N-no,” Thorax said, hanging his head. “I don’t.”

“Then try it,” Pharynx implored, his voice shifting, becoming warmer, less gravelly and harsh as he was enveloped in a light shimmer.

Thorax swallowed as he looked up. His brother’s usual sinister expression was now on the face of a hulking blue earth pony with a white blaze - and then it dropped away, leaving only a slightly dopey smile. The stallion looked down at Thorax, cheerily.

“Hi there, little fella,” he said, in a slightly goofy voice. “What’re you doing here?”

Thorax felt his face growing hot - he’d never admit it, but he found ponies… attractive. It was something about their warmth, the way they smiled, the fur all over their bodies… and the size, of the males. He swallowed, forcing his friendliest smile - something he never got to use in the hive.

“I’m just, uh, out here trying to make friends!” Thorax said, uncertainly.

“Gosh!” The oafish pony exclaimed, batting his thick eyelashes. “Real special friends?”

Thorax nodded, swallowing again as he leaned up to the pony, heart thumping, the strangeness of the situation giving him a kinky thrill.

“R-real special,” he said.

Pharynx craned his neck down, pressing his lips against Thorax’s muzzle. Thorax fluttered frantically but didn’t protest, moaning as he noticed all the differences between this kiss and the ones his brother usually pushed on him. The tongue was clumsy, thick, sliding into his mouth slowly, like the plodding creature it belonged to.

When Pharynx nipped or kissed him, he could feel the cold hard chitin pressing against him, the sensation dulled through his own carapace. What he felt now was a pair of deft, fleshy lips, that teased, sucked, mouthed him gently, if inexpertly. When the horse pulled away with a snort, he had that same self-assured, cocky expression on his face.

“Now, take my love,” Pharynx demanded, a little of his characteristic growl creeping into his voice.

Thorax screwed up his eyes, focusing. There, glowing deep inside Pharynx like a tiny, smoldering ember, was a burning nugget of love, usually hidden away. Thorax would usually never have been able to find it, but when he was starving like this his senses were heightened, more powerful.

Sucking in through his fangs with a hiss, he pulled the love towards him, tasting it on his tongue as he drank. He could feel the shape of what Pharynx loved as he fed - the hive was there, stable and secure, their Queen, for whom he had unwavering loyalty - and just a dash of Thorax himself.

Thorax shuddered with pleasure as he swallowed the meagre portion of his brother’s love, feeling himself growing healthier once more. He squirmed, struggling to draw more out like a foal sucking harder on a straw in an empty cup, hoping to get anything out of it.

His eyes flew open - the ember was being closed away, hidden, made completely unavailable to him, and his forked tongue flicked out, desperately, trying to catch any lingering specks of love hanging in the air. He was still hungry!

“Pathetic,” the pony said, his expression turning grim. “Are you sure you’re a real changeling?”

Thorax scurried back as the lumbering beast approached, his strong, heavy hooves leaving grooves in the ground. His heart pounded again, fear tinged with excitement, imagining that huge body looming over him, grasping him, mounting him, penetrating him.

“I thought changelings were monsters. I thought they were strong, taking from us weak ponies,” Pharynx hissed, peering out from the earth pony’s eyes. “What a feeble excuse for a changeling you are.”

Thorax swallowed, shame burning in his throat, but from his low angle, he could see the creature’s fat sheath, and its even fatter cock, the broad head slipping out, dangling lower and lower. It looked enormous, and Thorax realized with some shame he was panting again, his own shaft sliding out, too.

“You’re lower than a grub,” the pony sneered. “Lower than the ponies you’re supposed to feed on.”

“Y-yess,” Thorax moaned, speaking finally, stepping forwards to meet the hulking horse in front of him. “I’m n-not worthy of serving even you…”

Pharynx smirked, sitting back on his broad earth pony backside, his heavy balls resting on the ground. But Thorax’s attention was elsewhere, on that that pink, throbbing hardness, glistening with fluids. Thorax imagined how it would feel inside him, and his pulse raced even faster.

“You’re right. You’re not worthy of it,” he growled, his voice sounding strange coming from the pony in front of Thorax. “But you should worship me anyway.”

“Y-yes sir,” Thorax whimpered, humiliated at Pharynx’s request, but too turned on to even consider saying no.

Thorax reached out with his chitinous hooves, placing one on either side of Pharynx's throbbing pony cock. It was more solid than his ovipositor, maybe equal in width, but heftier. Thorax could tell it would feel enormous when it was thrust up his backside, and he needed both of his hooves to hold it steady while he stroked up and down.

Pharynx's flare was already visible, blunt, hard. Curious and eager, Thorax ran his forked tongue along the pony's cockhead, feeling just how fleshy and thick it was. A dribble of precum slipped down onto his tongue and he licked it up, trembling, comparing the taste to his brother's usual fluids. Bitter.

"Look at you," the pony snorted. "A so-called changeling, slurping all over a pony's cock. You've fallen so low you're pleasuring your own enemies."

"Y-yes, I'm, I'm not worthy to call myself a changeling," Thorax agreed, arousal and shame warring in his heart. "I'm just a ... shell. A hole to b-be fucked by anybody."

"Even a pony," Pharynx sneered. "A disgusting, pansy-ass faggot pony is better at taking what he needs than you, Thorax."

Thorax whimpered, but the telltale throb of his ovipositor said that at least part of him was enjoying the humiliation. Long ago he'd have wondered what was wrong with him, but now he was so dizzy with lust he barely cared.

Using his tongue, wrapped around that massive shaft, Thorax guided Pharynx’s erection to his mouth. Gulping, he slowly opened it, pausing a moment… and then pulled his lips down over his fangs, opening his mouth as wide as possible.

The flare slipped in, taking up a massive amount of space in his muzzle, and in short order Thorax began to panic, feeling it stuck there, wedged just before his throat. His wings buzzed frantically - until he felt Pharynx’s heavy hoof on the back of his head, pushing him down, the flare sliding deeper into his mouth, to the back of his throat. Breathing through his nose, his mouth full of hot horsemeat, Thorax pushed himself down further, down towards the base got thicker.

The pony groaned with pleasure as his hoof guided Thorax down. Like most changelings, Thorax didn’t have a real gag reflex, and by lining himself up right the fat pony cock slipped right down his throat. Pharynx stared, feeling his alien balls throb underneath him, at the bulge in it, slowly moving back and forth as Thorax bobbed his head.

“You’re g-good at this, changeling,” Pharynx muttered. “Better than a pony. It’s like you were made to suck cock.”

Thorax could only weakly mumble in return, his mouth stuffed his ponycock. His ears were laid back in shame at his brother’s comments, knowing they were the most vile insults for a changeling. But his cruel words only made him want his length inside him more, throat stretched taut around the pulsing length invading it, his jaw feeling like it would unhinge completely soon.

He lost himself in the fantasy, moaning. He would be a changeling on a mission to drink love - and he’d fail, and the very pony he was terrorizing would laugh, mocking him… before approaching with a towering erection.

“Do you like being mastered by a pony, you pathetic grub?” Pharynx rumbled in his disguise, smirking as Thorax looked up with his eyes wide, trembling as he was so masterfully dominated, as he so willingly submitted, hating himself while he loved it.

Ashamed, Thorax bobbed his head once in a ‘yes’ motion, moaning as he felt his brother rocking his hips, that bulky flare working back and forth inside his throat, scraping it. It was such a unique violation, such a tender way of showing how little Pharynx cared for his comfort, showing him his only valuable use.

“Get off,” Pharynx ordered, yanking him backwards off of his cock.

Thorax spluttered with surprise, eyes blinking in shock as the hulking earth pony nudged him easily onto his front. The hoof that darted between his legs brushed his ovipositor, and he moaned, but it was only aiming to lift his rump. Trembling, Thorax looked behind him to see that huge beast about to mount, just like his fantasy, imagining how it would feel…

“WAIT!” he said, lifting a hoof urgently.

Pharynx paused, glowering at his brother, as if to say ‘this had better be good’. Squeezing his eyes shut, Thorax allowed his form to change and twist, until he was a scrawny yellow unicorn. He’d been a pony before, but this time was different. There were a thousand new sensations for him to notice - for instance, the way his loose, flowing tail flicked aside, showing off the new… opening, he had.

“...You want to be a pony?” Pharynx asked, sneering. “Fine. You’ll be my slutty little filly, and I’ll be the big, dumb, horse about to fuck you.”

Thorax swallowed as he heard Pharynx rear, and then felt his weight come down on his back.

“Ahh!” he cried out, wincing. This form was much heavier, but he kept standing, straining, shuffling his hooves apart to make it easier to be penetrated. His tail kept flick, flick, flicking to the side, almost instinctively, trying to get out of the way of the hefty cock that would soon be seeking his back passage.

Snorting, heedless of Thorax’s worries, Pharynx thrusted, jabbing the air as he shuffled forwards on his brother’s back. Eventually he felt himself nudging flesh, and then he slid the slippery cockhead around to try and find an opening. He found one, eventually, a tightly closed pucker that didn’t seem built for things to go inside it…

“GAH!” Thorax cried, feeling that same tightness from his own angle, as the fat, blunt head pushed hard against his clenched hole.

Changeling passages were designed to pass eggs and receive ovipositors, they were incredibly stretchy, sometimes uncomfortably so, and they were equally muscular all the way along, including the opening. This creature’s backpassage was tight, some kind of muscular ring squeezing it shut to entry from foreign invaders.

Thorax shuddered, gritting his teeth as he tried to force his hooves wider apart, experimenting with clenching and relaxing different muscles to try and make Pharynx’s entry easier. Eventually he worked out that if he pushed slightly, for some reason that made the hole… looser? He wasn’t sure, but just as he was experimenting with opening up back there, Pharynx began to softly nudge his hardness into the tight, crinkled hole.

The pony’s cock was drier than a changeling’s, the tip constantly oozing thin fluid but most of the shaft was more or less unlubricated. That, and the horrible size issue, made initial penetration quite an affair.

With Pharynx’s hooves clasping Thorax’s waist, the smaller pony panted, eyes wide, veins straining on his forehead as he felt that bludgeon-like cock push harder, and harder, and harder against his tight hole. Something had to give, eventually, and poor Thorax’s backside was the first to give in.

“AHH!” Thorax screamed again, banging a hoof on the floor as he felt that enormous member wedging itself inside him. It was so, so, impossibly big, but behind the pain it thrilled him to know he was taking it, that he would be taking it ALL inside him.

Grunting, Pharynx pushed that throbbing mass of meat deeper into Thorax’s anus, stretching the pony’s ass beyond any reasonable limit as his little brother cried out in pain, tears stinging the corners of his eyes. It was too overwhelming, in so many ways, as that fat cock probed deeper and deeper, barely able to fit inside the little pony it was reaming, gliding very slowly across the inflamed g-spot that Thorax was now discovering through his pain.

“Ohhh, Chrys- I mean, C-Celestia,” Thorax mumbled to himself, feeling sparks of pleasure glowing inside him, desperate for more of that length inside him, even if it split him in two.

Through wailing, tears, and gnashing his teeth as Pharynx shoved his oversized length heedlessly deeper into him, Thorax began to rock slightly, puzzling Pharynx - until he realised Thorax was trying desperately to thrust his rump back onto the cock slowly invading it.

“You slut,” Pharynx hissed, almost fondly. “Are you that desperate to be defiled by pony cock?”

Thorax groaned, his face red, streaked with tears - but he couldn’t, wouldn’t deny it, despite the shame that ached in his soul, telling him he should never admit he enjoyed this.

“Yes! Oh yes PLEASE mister ea- mister pony, sir, f-fuck me!”

Pharynx obliged, squeezing Thorax tightly as he dragged that massive length backwards, the flare pressing hard against all Thorax’s sensitive spots.

“Wh-what a useless excuse for a changeling… even for a pony,” he panted as he shoved his fat cock right back inside, prompting a panicked whinny from Thorax. “Do you know how low you are?”

Thorax could only moan, feeling his own cock throbbing underneath him, twitching and beading with precum with every stroke inwards from Pharynx. He could tell his hole was stretched obscenely around the enormous length, and his better senses told him this was horrendous, it was too big for there.

His libido had grabbed the reins, though, and despite the pain he panted, hungry for more, needing to feel that huge beast spooge right inside him.

“You don’t even deserve this,” Pharynx snorted. “Y-you’re not worthy of taking my seed. Not even good enough for a stupid -ngh!- dumb -ngh!- beast -NGH!- … to see you as anything more than a h-hole to satisfy himself in.”

“I know,” Thorax moaned, his face bright red with the shame and heat of the situation. “I-I, I’m so...ngh… ow… so grateful you allow me to s-serve you anyway, sir.”

Pharynx huffed, ignoring him, focusing on his own pleasure. Those tight, constricting walls that were forced well beyond their limit by his massive shaft were squeezing and massaging him, spasming around him as Thorax’s body said over and over that this was too far, too much. Thorax himself merely gasped and whimpered as the thrusts began to come quicker and quicker, that ring of muscle giving up completely and allowing Pharynx to pound himself in and out with frantic haste.

“Oh oh oh! OH!” Thorax cried out loud as the pony on his back thrust in and out, his eyes wide at the mixed feelings of pain and pleasure, every eager stroke stimulating his prostate, until, suddenly-

“NGggh!!! Oh CHRYSALIS! GAH!” Thorax thrashed, eyes flying open wide as he felt the pony orgasm hit him.

His cock pulsed, and suddenly a jet of off-white fluid spurted out of his throbbing, quaking member as his ass squeezed and clenched around the far larger cock thrust so far inside. Thorax gave a moan as he released load after load onto the cold ground, gasping as he felt Pharynx ram himself as hard as he could into his little brother’s convulsing, tightening backpassage.

“GRR-Rrrf!” Pharynx grunted loudly as he fired off into Thorax’s tight, clenching hole, hot, white cum squirting straight up into his bowels as he was filled, claimed by the strange creature on top of him.

Thorax’s moans rose in pitch, and he panted, feeling his squeeze harder as his body managed to drag a few more seconds of ecstacy out of that wonderful, shameful feeling of his brother cumming inside him. The volume was truly amazing, and Thorax gasped and shuddered with each pump of Pharynx’s overloaded testes, the hot, oh-so-hot fluid filling him like nothing had before.

“Ah-h!” Thorax whimpered as he felt those spurts continue, filling his bowels to the limit, uncomfortably.

Gritting his teeth, he rocked back and forth to relieve the pressure - and then moaned anew as he felt his motions churning the cum back and forth inside him, his brother’s cock an immovable obstacle that kept him plugged up as even more fluid gushed into him, unstoppably, swelling his stomach slightly with the sheer volume.

Eventually, Pharynx snorted, feeling the pressure himself, pushing on Thorax’s back to yank his cock backwards, hard. Thorax couldn’t but yelp, wincing as he felt the swollen flare stuck inside him, being tugged hard, once, twice, three times, and then finally that massive shaft was pulled free, leaving Thorax’s backside gaping from hard use, cum spilling out of it. More spilled out of his rear alone than he’d produced during his own orgasm.

“You should have turned yourself into a mare,” Pharynx hissed, as the flicker of green transformation magic enveloped him. “You’re never going to get to use that pathetic thing between your legs no matter what you look like.”

Panting, moaning, Thorax nodded, ashamed of himself, of his lusts,

Ashamed because he knew he would be begging to be used by Pharynx again, soon.
