Submissive Thorax learns from a young age how much his brother likes burying his ovipositor inside him, dominating him brutally until he fills him with sticky fluid - the problem is how much Thorax likes it, too...
Pharynx has always looked out for Thorax, but sometimes he was his little brother's own worst bully. As puberty started, Pharynx began looking at Thorax differently - maybe his submissive little brother wasn't so worthless after all...
Thorax can't believe it at first when his brother pins him down and rams his ovipositor hard inside, but he's even more surprised when he finds himself moaning wantonly and begging for Pharynx's loads. Their relationship changes over the years, but Thorax never really stops being his brother's fucktoy... Even when he's supposed to be King of the hive.

Thorax being a needy slut :3c
(A commission I received recently. Artwork by the inimitable Kyokimute.)
Thorax happily played with his dolls, imagining a world where he had been born a pony instead, and he could live out an idyllic life being taken care of by a Mom and Dad - instead of laid in a clutch by the Queen and then left to fend for himself.
...Well, not quite by himself. Thorax smiled, thinking about his big brother. He was lucky to have Pharynx around… even if he wasn’t always that nice to him, he always stuck up to bullies when they bothered Thorax.
Speaking of which… Thorax cowered as three other immature changelings approached, his eyes wide with nervousness. Just as he began to get really scared, Pharynx appeared, as if by magic. Thorax felt his heart flip with relief.
“Step away from my brother,’ Pharynx growled, the other juveniles whipping around and gasping.
“W-we were just complimenting his dollies!” one of them stuttered - and then screamed with the rest as Pharynx transformed into an enormous rock insect, roaring at them.
As the bullies fled, Thorax stepped forwards, smiling gratefully.
“Thanks, Pharynx,” he said.
Instead of smiling back or saying ‘you’re welcome’, Pharynx grabbed Thorax’s foreleg - and began to thwack him with his own hoof, grinning.
“Why are you hitting yourself? Why are you hitting yourself?”
“Pharynx, cut it out!” Thorax pulled back, his ears back against his chitinous skull.
“They’re right you know,” Pharynx grumbled, dropping Thorax’s hoof. “You need to have tougher skin.”
Pharynx looked over his pathetic little brother one more time. As he did so, his expression changed, the pubescent stirrings inside him making him look at his brother… differently. Yes, he wanted to protect him, even more than he wanted to defend the swarm and one day hoped to be a powerful changeling warrior, collecting love from weak, pathetic ponies.
But Pharynx also saw his job as teaching his little brother to toughen up, dishing out harsh insults and bullying just to prepare him for the outside world.
Maybe the little brother who’d been a punching bag so often could also have… other uses. Maybe Pharynx could teach him something new about the world. That the weak would be used by the strong.
Pharynx narrowed his eyes, advancing on Thorax. He would teach his little brother all about what happened when you were too pathetic to stand up for yourself.
“Ph-pharynx?” Thorax asked, his mouth dry. “H-hey, you’re getting a little - mmph!”
Pharynx pressed his muzzle hard against Thorax’s open month, his slippery tongue sliding into his little brother’s. His wings buzzed as he felt the sweet taste of love flooding into his mouth, his baby brother’s virginial innocence, his wide-eyed confusion at what was going on. Thorax gave love like a pony, sticky, sweet, a thin and uncertain stream of it that Pharynx felt drunk on in seconds.
“Wh-whoa! Pharynx, I don’t like this!” Thorax pulled away, turning his muzzle away to avoid another kiss, heart and mind racing as his body was filled with unusual new signals.
Turning away only presented his neck to Pharynx, who’s tongue slid out, flickering against the thinner, more sensitive chitin that covered Thorax’s neck. He gasped as he felt his big brother’s tongue slide up and down along it, tasting him in a strangely intimate way.
“You don’t need to like it,” Pharynx snarled, using a hard hoof to push his brother to the floor.
Thorax toppled over onto his back, trying to scramble onto his front. He finally got his hooves under him, trying to stand, when he suddenly felt Pharynx come down hard on top of him, his own hooves digging into Thorax’s back, pinning him down with his rear raised.
“H-hey, what are you doing?” Thorax said, eyes wide as he tried to scramble away.
“Shut up, you weakling!” Pharynx jeered, jabbing the edge of a hoof against Thorax’s side. His ovipositor slid out of its hiding place, glistening translucent green and black, a semi-transparent tube that oozed slick, sticky fluid. It throbbed in the cool air, and with a fanged grin, Pharynx began thrusting his hips clumsily, trying to find his brother’s entrance.
“Pharynx! Ph-pharynx, stop!” Thorax pleaded, sensing his brother’s mood, not understanding it fully but afraid of it anyway.
Afraid, and a little curious, a little excited - but Thorax wouldn’t let himself think about that.
Thorax gasped as he felt something slick and firm spreading warm slime against his backpassage, oozing against his hole. Instinctively he clenched against it, but his muscles tensing only made Pharynx grin wickedly, knowing he’d got the right spot now.
“This is what happens to weak little pansies who can’t fight back, little bro!” Pharynx snarled, as he began to apply hard pressure, trying to force his way inside his brother’s virgin hole. “I-if you’re WEAK, someone STRONGER will always… ngh… be there to f-fuck you!”
Thorax’s eyes went wide and he let out a peculiar braying scream as Pharynx shoved his hard, throbbing shaft inside of him. His muscles fought to keep the invader out, but his big brother was far stronger, and his length, large for his age, was already buried halfway inside him. The thick, oozing fluid that constantly pumped out of the end made the penetration less painful, but still, Thorax felt sure he would be ripped apart by the sheer size of his brother’s member.
“AHH! Pharynx! P-please, stop!” Thorax begged, feeling his backpassage stretching painfully to accommodate Pharynx’s hardness.
The changeling above him ignored Thorax’s weak protests. Drinking love was delicious, and felt amazing… this… This felt like a whole world above that. Grunting, Pharynx shoved his length deeper inside of Thorax, dragging it back and gripping him around the waist more tightly, pushing back harder inside. His length felt like it was being squeezed and gripped all down the rubbery shaft, massaged by his own little brother’s unwilling passage.
Thorax whimpered, laying his ears back and passively accepting as his hole was used for his brother’s pleasure. The initial stabbing pain of penetration was gone, but his passage ached as it was stretched so very far, and every thrust inwards made him gasp loudly, dizzy on the scent of lust filling the cave.
“Ngggh, you’re so pathetic, Thorax!” Pharynx growled, feeling powerful, dominating his helpless, submissive little brother. “You’ll n-never be any use to the hive! You’re only useful as a f-fuck toy!”
Crying, Thorax moaned in protest. This felt so wrong, so dirty… and yet…
And yet somewhere in there he could tell, a tiny ember of pleasure was burning, concealed by the painful distension of his hole. That massive, thick length made him ache every time it was slid deep inside, but every time it did so it pushed firmly against some part inside that felt… good.
Pharynx grit his fanged teeth, thrusting harder and harder into Thorax, who was now completely limp underneath him, his body no longer fighting to keep the invading shaft out. Pharynx’s nostrils flared, catching the scent of sickly sweet love in the air again, and he snarled, working his hips harder and faster, giving his thrusts more power, trying to fuck Thorax so hard the pain would override the pleasure.
You’d have to be a complete failure of a changeling to ‘love’ someone who did this. That was practically… pony.
Meanwhile, Thorax’s eyes were wide again, but this time it wasn’t from pain. He winced and cried out as Pharynx’s abuse of his backpassage increased, a deep burning ache inside him and stretching around that tremendous ovipositor - but the pain was tinged with pleasure, laced with an amazing feeling Thorax found himself getting addicted too.
Moaning, he shoved his rump back shamelessly, wanting more, wanting his brother buried deep inside him - more than that, wanting his brother to take him, use him, give him more and more of this forever. It felt like he belonged here, and despite his shame, he felt his own meagre length sliding out, oozing thin liquid of its own, dripping onto the ground.
Thorax screwed his eyes shut, tears of shame burning in them, as Pharynx’s wings buzzed, his own pleasure intensifying as he used Thorax’s hole brutally, grunting as he buried himself again and again inside that impossibly tight passage. He could feel a climax approaching the peak he’d only reached previously by using his hooves. This felt so much better....
Pharynx was pounding Thorax, reaming him hard, the force of his thrusts making his whole body rock as Pharynx’s hips slammed his length home again and again. He grit his teeth, knowing he could only keep this up for so long, feeling his peak coming at him fast like a powerful, unstoppable swarm, he couldn’t hold back, couldn’t stop, couldn’t-
“NGGGGH!” Pharynx snarled, feeling himself orgasm deep inside Thorax’s constricting hole.
Pharynx rammed himself home as his length throbbed, globs of slime were pumped out of his ovipositor, flooding Thorax’s insides with warm, sticky goo. The peak was intense and satisfying like nothing else, and he grunted as he filled his brother with load after load of his own changeling cum.
Thorax felt his brother cumming inside, his eyes wide and his mouth an ‘o’ of shock as Pharynx buried his shaft hard and fast inside him. And then, as he felt his big brother’s hot, fertile ooze pumping up inside him, he came for the first time, his backpassage clenching and massaging Pharynx’s length as he moaned and thrashed about below him.
His own slender ovipositor fired off one, two, three strands of thick, sticky fluid onto the ground as he whimpered, orgasming over and over, trembling as his die was cast, not knowing it then but forever a slave to his big brother’s achingly hard length.
Thorax moaned as Pharynx drew back, sliding his still firm tube out of Thorax’s hole. He felt it being dragged out of him, hot, sticky slime spilling back out of his destroyed entrance, stretched well beyond his limits.
As Pharynx dismounted, Thorax collapsed into his own puddle of ooze, whimpering pathetically at the feeling of it smearing all over his belly, mixing with the dirty as he flailed slightly, trying to rise and failing.
Pharynx laughed, glowing with energy after firing his load deep inside his brother ruined hole.
“You’re a real loser, Thorax. Learn to fight back!”
And with that, he left the cave, leaving Thorax on his own, heart thumping as he tried to understand what had just happened.
***
When Thorax had finally risen from his sticky spot on the floor, he found it hard to walk. His short limbs trembled, and every step made him gasp as a jolt of pain shot up his spine, his brother’s recent use of his poor hole leaving it aching deep inside.
He walked away as quickly as he could, ashamed of the puddle of ooze that was left on the floor, half his own meagre issue, and the other half overflow from his overly full passage. He could still feel the rest of Pharynx’s fluid warming his insides, still picture vividly the sensation of that glorious shaft plunging into him again and again.
Why had that felt so good? It felt wrong, too. Thorax knew it was wrong, it had felt like he was being torn apart by a tree trunk invading his hole… He could feel Pharynx’s malevolent intent, rolling off him in black clouds of lust that made Thorax’s mind foggy with confusion and lust of his own.
His insides burned with shame at the thought of Pharynx touching him that way, but far more overwhelming was the excitement that raced through him whenever he pictured it.
Over the next few days, Thorax could think of little else. He woke up from ‘nightmares’ where figures in shadow with huge, hulking ovipositors pinned him hard to the ground and fucked him until he leaked cum all over the floor - and awoke, panting heavily with his own shaft pointing directly up, dribbling clear fluid onto his stomach.
He could barely meet Pharynx’s eye whenever they met, keeping as far away as possible, not wanting his big brother to sense the lust running off of him, to know how much he’d loved being utterly dominated by him. And all the while Thorax secretly hoped he would find him and do it again.
After four days, Thorax couldn’t take it any longer. He knew on some level it wasn’t normal that he wanted this, that he craved another changeling dominating him… Especially not his own brother. But he couldn’t deny it, he wanted more, more of whatever that had been, more of being pinned to the floor, moaning as he was fucked hard into the ground.
More of submitting to a real male.
With faux nonchalance, Thorax fluttered through his brother’s quarters, as if he’d just ended up there on a whim.
“Oh, hi, Pharynx,” he said, with a nervous smile, as his brother glared at him from his nest. “I was just, going outside…”
“Outside? For what?” Pharynx stepped out of the shadows, and Thorax felt his heart thump faster, just seeing him.
“Oh, haha… I don’t know. To pick flowers? Make some new… pony friends?”
Pharynx glared at him, taking an angry step forwards. Thorax felt a thrill run through him, his brother’s anger only exciting him more for some reason. When he looked at him through those slitted purple eyes he seemed so powerful, so strong. So unlike Thorax himself.
“You cannot be serious,” Pharynx snarled. “You cannot be fucking serious.”
“I, I am,” Thorax lied. “I don’t see why not, I think it would be… lots of wholesome fun.”
Pharynx stared him down, and Thorax trembled, his mouth dry as his pulse pounded in his ears.
“You’re pathetic,” Pharynx finally said. “A disgrace to the entire changeling race.”
‘Yes, yes, please, tell me I’m worthless,’ Thorax thought to himself, staying silent.
“Didn’t you learn your lesson last time? Weak little grubs get taken and USED by anybody who’s stronger than them. It’s our job to be strong, to steal love from ponies. We USE them.”
Thorax nodded, swallowing.
“I-if you think I didn’t learn my lesson last time,” he began unsteadily. “...Maybe you could… show me again?”
Pharynx eyed Thorax suspiciously for a moment, before a grin began to spread across his face. He too, hadn’t been able to get the feeling of fucking his brother out of his mind. It made him feel powerful, like the strong, aggressive drone he’d one day be, leeching love from ponies and fucking his choice of more submissive members of the hive, unable to fight back against it.
There were words for changelings like Thorax, insults, because only the weakest males would allow themselves to be taken like that, too pathetic to stop a bigger, stronger male from using them. Very rarely would a male changeling submit willingly to being another’s fucktoy, and that was usually done begrudgingly, to avoid a dispute.
Here Thorax was, practically begging to feel Pharynx’s ovipositor thrusting hard into him, craving the feeling of being taken by his own big brother.
“You’re a dirty little broodslut, Thorax,” Pharynx muttered, stepping towards him.
He circled his little brother, who trembled on his tiny hooves as he heard that insult directed at him for the first time. Pharynx snarled and nipped gently at Thorax’s tailfin, and the smaller changeling gasped, forcing it erect and out of the way of his hole.
“I suppose I can teach you… One more time,” Pharynx said, as he mounted his younger brother.
Thorax gasped, unable to stop himself smiling - before he felt his brother’s slimy, dripping length pushing against his still-sore entrance, making him cry out in shock. Pharynx’s hooves held him in place, and before Thorax could question the wisdom of this idea, the dominant changeling’s shaft was forced hard into his hole.
“AAHHHHH!” Thorax cried out again, his eyes wide, and Pharynx could sense his fear and pain.
Smirking, he pushed his length deeper, and Thorax let out a moan, his eyes burning with tears at being invaded so harshly.
“S-so…. Big!” he finally managed, but he made no move to leave. His heart thumped hard as he subtly spread his hooves wider, a better position for taking more of his big brother’s length inside him.
“Maybe you’re just small?” Pharynx snarled, nipping his ear softly before jerking his hips forwards powerfully. “Weak. Pathetic.”
Thorax moaned in pained pleasure, his body adjusting to the feeling of having something so massive inside it as the well-lubricated thickness began to move slowly backwards, feeling like it was dragging his insides with it. With a feminine shudder, Thorax nodded his head, loving this feeling, being so totally dominated by another male, his hole claimed by a fat, thick ovipositor that belonged to his own big brother.
“Mmmm, you feel so good, little fuck toy,” Pharynx hissed, as he pushed his hips hard down, shoving his shaft in as deep as possible.
Like all changelings, Thorax’s hole was slick and inviting inside, warm, with powerful clenching muscles that could force out a clutch of eggs. Those same muscles were now massaging Pharynx’s length, drawing him in deeper, all of the most sensitive spots being stimulated as Thorax trembled in sweet agony beneath the older changeling. It felt amazing, once again, and Pharynx slid back once more, eager to plunge back inside the warm tightness of his brother’s nook.
“Ohhhh sweet Queen Chrysalis!” Thorax cried out, as Pharynx began to fuck him in earnest, that long fat tube plunging in and out with wet, sloppy sounds as he used his baby brother’s backside for his own pleasure. It felt so good, so so good to be so utterly controlled, to be taken this way.
“Y-yeah, you filthy little eggdump,” Pharynx growled as he continued pumping his hips, one hoof on Thorax’s fragile wings, forcing him further to the ground. “I told you, you’re only useful for other changelings to fill with their seed. Y-you’re an EMBARRASSMENT to the entire hive.”
Thorax moaned wordlessly, nodding, for some reason loving hearing his brother say these things, shoving his rump back against Pharynx to get more of that glorious hardness buried inside, his own meagre shaft poking out uselessly into the cool air. Pharynx could feel the sick, burning love and lust roiling off of Thorax, but instead of ignoring it this time, he drank deeply, using it as fuel for his rough, forceful hip movements, finding his body naturally bucked and pushed his ovipositor in and out of Thorax’s willing tightness.
“Y-you ought to thank me,” he snarled. “Thank me for making you useful. G-giving you one job… letting your big brother fuck you… At l-least now you’re slightly less worthless.”
“Th-thank you,” Thorax mumbled, and in response Pharynx grit his teeth and rammed himself home with a grunt, prompting a frantic squeal from Thorax.
“Say it l-louder you little *nghhhh* fuckhole! Thank me for s-showing you your PLACE.”
“Thank you, Pharynx!” Thorax moaned more loudly, feeling that hot hardness plunging into him over and over, making his shaft twitch in the air. “Th-thank you for showing me I’m nothing but a, a worthless fuck toy, a vessel for other changeling’s powerful seed!”
Pharynx snorted, snarling as he gripped Thorax tightly, his hips working doubletime now, pounding his poor brother’s sore backside hard, pleasure building on pleasure. Thorax groaned, squeezing his eyes shut as his body was wracked with the sensation of pleasure tinged with the pain of being stretched and pounded so very hard, hearing his brother’s heavy breathing coming in snorts and grunts from behind him.
“You f-fucking SLUT, Thorax! You’re sick! Y-you’re like one of those faggot ponies who likes taking it up the ass!”
Pharynx closed his eyes, unable to focus on anything but the exquisite tightness of his brother’s hole, the moans and gasps from underneath him, the sheer power he felt from taking so much control of someone so pathetic and worthless, showing him his place underneath him in the hive-
With a bestial snarl, Pharynx slammed himself home, making Thorax shriek, and then moan, as he felt glob after glob of warm, thick fluid filling him up, swelling his stomach, sliding past that magic spot inside him…
Thorax moaned again, as he orgasmed too, a pathetic little stream of thin liquid hitting the ground as Pharynx held him hard in place, not letting him move away even an inch as he drained his load inside his baby brother’s backpassage. They both trembled, Thorax on a whole new plane of bliss from being so thoroughly dominated and broken, Pharynx from sheer exertion and the rush of endorphins he was feeling.
At last, the pumps of hot, sticky ooze stopped flooding into Thorax, and Pharynx unceremoniously dismounted, yanking his length out of Thorax’s backside. Thorax moaned, hanging his head, panting, as Pharynx flew over to his nest once more.
“Come back here after your lessons tomorrow,” Pharynx said. “Until then, get lost!”
Despite his trembling legs and aching, well-used hole, Thorax obeyed, fluttering his wings to fly away down the corridor.
Now he knew for certain he had to have more of that.
Thorax was trying to stay away from Pharynx again. God it was hard, to get the thought of his swollen member out of his head, to stop imagining being taken and claimed, pumped full of load after load as he moaned submissively.
Just imagining that fat, black and green shaft hanging in the air above him, drooling ooze, as his brother smirked a cruel, callous smirk. Dangling, dribbling, delicious…
Thorax realized he was drooling. He wipe a corner of his mouth and shook his head to clear it. What was wrong with him? He tried to think about something other than his brother’s shaft, but it was so hard.
Thorax had continued his trysts with Pharynx as they both grew up, offering his body again and again for his brother, despite the fact that where his thin little wand stayed tiny as ever, Pharynx’s ovipositor only grew larger, stretching Thorax more and more with every rough fucking. He’d end up sore and limping, barely able to walk - but he always crawled back for more.
Sometimes Thorax tried to keep his distance from Pharynx. But one way or another he’d end up underneath his big brother sooner or later. Sometimes because Pharynx came to wherever Thorax was sleeping, and took what they both knew was really his. Sometimes because Thorax had shamefully slunk back to his brother, begging to feel his ovipositor deep inside him.
When Thorax woke up the other day, his hole sore and leaking, slick, slimy fluids, he’d told himself that was the last time. But now, like any addict, he found his resolve wavering. Would it be so wrong, so bad, to just do it one last time?
Thorax bit his lip with a fang. He always felt guilty, no matter what he did. He felt guilty for being a worthless disgrace to the changeling hive - and then when he acted like a changeling was supposed to, stealing love from ponies, he felt guilty for that, as well. Thorax didn’t think the other changelings ever felt guilty. So that was just one more way he was a failure.
Fuck it. If he was going to be a disappointment, he could at least wallow in his shameful behavior. He could at least be good at being a fucktoy for a better changeling.
...And it would feel like heaven while he did it…
***
“Ph-pharynx?” Thorax called into the darkened cave, his mouth dry with nerves.
His heart was already thumping harder. This was a bad idea. He still hadn’t really recovered from the last time…
But here he was. Calling out for his big brother. Pathetically begging for his thick, throbbing length inside his tightness.
Thorax crept in further, swallowing. There was no sign of his brother... Until Thorax noticed the dark black shape in one corner, chest rising and falling as Pharynx slept. Licking his lips, he approached, clearing his throat.
"Ph-pharynx?" He said, more clearly this time.
Pharynx opened one eye, glaring at whoever was disturbing him. When he noticed it was Thorax, he smirked, sitting up a little.
"Oh, you're back for more? What a surprise," he said, mockingly. "I told you all you were good for is taking my loads... Looks like you proved me right, huh?"
Thorax whimpered. The cruel words stung - but they made his own ovipositor perk up, chitinous plates sliding apart to let it slip down. He felt addicted to Pharynx, all of him, his sticky, oozing cum, his thick changeling hardness... but especially his cruelty, his easy domination of Thorax, keeping him under his superior hoof with ease.
"Please, Pharynx," he whispered, turning to the side to show off his pathetic little hardness. "I need it."
"How much?" Pharynx asked, raising an eyebrow. "Show me what a desperate little cumslut you are. Fucking your own big brother. Moaning like a little pony while he's filling your hole."
Thorax moaned in pleasure, nodding at Pharynx's words. Trembling, he stepped forwards, stroking at the thin plates where Pharynx's fat hardness would slide out. Pharynx snorted, shifting as he began to grow erect, feeling Thorax's chitinous hooves on his length.
"Fuckk," he moaned, laying back and allowing his little brother to worship his ovipositor.
Thorax’s hooves ran up and down the ribbed, throbbing, gelatinous length, lowering his fanged mouth cautiously. His forked tongue slithered out of his mouth, wrapping around Pharynx’s throbbing shaft. He slid it upwards, collecting Pharynx’s oozing fluids and eliciting a excited hissing noise from the other changeling.
Blushing, Thorax rolled the thick juices into his mouth, moaning softly as he swallowed. The taste was chemical and sour, and yet, he loved it, loved running his skinny tongue along another, bigger changeling’s hardness. He moved his mouth down again, parting his lips around the tip of Pharynx’s length.
Unlike a pony’s cock, a changeling’s ovipositor was mostly hollow, a long, fleshy tube which could stretch and expand to pump eggs into a host, willing or unwilling, the opening in its tip far bigger. Thorax’s lips closed tenderly around the end of it, tucking his fangs under his lips as he slid his tongue gently into Pharynx’s hole, hearing his brother’s wings buzz at the stimulation.
“NGghh… You’re a good little pony, Thorax,” Pharynx mocked, with a sneer. “But why don’t you show me where you really want to be filled?”
Thorax reluctantly slowed his worshipful affection of his big brother’s length, but nodded, wanting this so badly. His eyes were full of lust and a sick adoration as he lifted his head, mouth dripping with saliva and sex juices, turning around, slowly, to present his tight hole to Pharynx. Gulping, he crouched, awkwardly lowering his rump to the throbbing organ below him.
He gasped, feeling it throb against his puckered entrance, whimpering with anticipation as he hovered, just on the edge of allowing it to spread his ring and enter him. Thorax had felt that massive bulk wedging into him so many times - why was it so hard to just make himself press down and let it in?
Thorax wondered if Pharynx knew how deliciously conflicted this was making him. It was easy to submit to Pharynx, to allow him to enter, to go bonelessly limp under his barrage of thrusting. It was something else to willingly impale himself on the swollen length probing his passage, to admit he needed, craved that shaft inside him so badly.
Thorax quivered, hesitating a moment longer - and then moaned as he forced himself down, feeling the spongey stiffness of Pharynx's length slipping up into him. The fat, throbbing tube spread him wide, and he grit his teeth feeling it, the ache a delicious pain that reminded him of how big his brother really was.
"Mmm," Pharynx said, simply, as he let Thorax impale himself on his throbbing hardness. "Tight."
Thorax gasped, pushing himself down further, feeling his innards rearranging themselves to make room for the intruder that pressed deep into his bowels. He whimpered, his slow descent somehow only making it more unbearable, able to feel every throb inside him, every place that big, thick shaft was stretching him mercilessly.
Finally, he felt Pharynx's crotch against his rump, and panted for a moment, giving a cry of surprise as Pharynx flexed inside him, smirking.
"How does it feel, slut?" Pharynx asked through a toothy grin. "To willingly sit on my shaft... to push yourself down on it... We both know you want this as badly as I do."
"Ngggh," Thorax panted, eyes barely focusing as he tried to lift himself, slowly, off of the slimy length invading him.
"It feels... wr-wrong," he said.
"Wrong, huh? After years of me fucking you, now it feels wrong?"
"N-no, no," Thorax started, swallowing as he turned, meeting Pharynx's eye. "It feels wrong... because I'm in control. I'm, I'm worthless. I'm just a breeding hole for you, Pharynx. You should be pinning me to the ground while you fill me with your mighty seed!"
Pharynx looked at his brother's pleading, desperate expression, and then snorted, grinning as his wings buzzed.
"You're right," he said. "For once in your miserable life."
Thorax yelped as the fat shaft he'd worked into his rectum was unexpectedly and painfully yanked out of him, Pharynx quickly rising, pinning him to the floor. His hole had barely begun to close before Thorax felt his big brother's shaft ramming against it, easily forcing his way inside as his hooves dug in and claimed Thorax's body.
"AHHH!" Thorax screamed from the shock, but despite that he felt his own little member throb slightly, the vicious, violent penetration arousing him, reminding him of how little his pleasure mattered to Pharynx.
"Chyrsalis, YES," Pharynx snorted, ramming his cock hard in and out of Thorax's backpassage. "Tight little broodslut!"
It was clear this wasn't going to be slow, gentle sex, working up to more vigorous fucking later. No - Pharynx was pounding the gasping, yelping Thorax into the dirt, sneering at him with a look of utter contempt… When he wasn’t snarling in pleasure, the tight, squeezing backpassage of his little brother feeling like heaven around his hard length, drooling ooze straight up inside his bowels.
“Ahhh! Pharynx!” Thorax moaned, not sure if he wanted to cry out for him to stop, to slow down… Or to pound him even harder.
Of course, it didn’t matter. He wasn’t in control, he never was. And that was what felt right, to be under his brother’s hooves, to be his toy, the dumping site for his oozing issue. Pharynx snarled, baring his teeth as he felt love pouring off of Thorax ashe fucked him, drinking it in, a decadent if perverted feast for a creature that ate love.
“You’re so w-weak, Thorax, you’re pathetic,” Pharynx groaned, as he felt his climax approaching. “I can’t believe you even call yourself a changeling. You’re nothing but a worthless hole for me to fuck.”
Thorax moaned weakly, nodding, his cheek crushed into the dirt. With every forceful shove inwards, his own length twitched underneath him, and now the thrusts were closer together, jackhammering his tight hole as the end loomed in sight. Thorax always felt his heart throb at the same time as his brother’s shaft, moaning in bliss as he felt that hot, thick goo spilling into his guts.
He didn’t have to wait long. Pharynx grit his sharp teeth, pounding Thorax hard, focusing on the sweet sensations around his length, until…
“NGgh!”
A torrent of thick slime spurted out of Pharynx’s length, his shaft flexing with rhythmic pumps as he unloaded in his little brother. Thorax felt that release inside him, and moaned with delight, banging one hoof on the ground as he felt his own pathetic length tremble and ooze all over his belly, his spasming backpassage milking Pharynx’s throbbing ovipositor as it lay buried inside him, his guts filling with the hot, slimy fluid.
When Pharynx’s orgasm finally came to an end, he yanked his still-dribbling shaft out of Thorax’s sore, abused hole unceremoniously. Fluids spilled out, backwards, dripping down to the floor, and Thorax found without Pharynx supporting him, his rear legs buckled and failed, making him collapse, panting and sticky, onto the floor.
“You’re pathetic,” Pharynx snarled, before he buzzed off to the corner where he’d been making his nest.
Thorax could only nod, smiling, his body awash in afterglow, his rear aching with recent, hard use. He knew he’d hate himself later, would try to resist again - but right then and there, he embraced what he really was, where he fit in - as his brother’s fuck toy. Not without shame - no, even then, Thorax could feel the horrible shame of it - but it was a dirty, erotic shame that only made this more exciting.
Thorax glanced over, barely able to lift his head, at where Pharynx was resting. He hadn’t kicked him out, so Thorax let his head drop, and sighed, waiting until he fell asleep himself.
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.
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.
Not long after that, Chrysalis had ordered the real attack on Canterlot, and been soundly defeated. As Thorax lay in the rubble, his heart ached, realizing while he was here he could never have the kind of pure friendship he’d seen those ponies share so easily. He bit his lip - he loved Pharynx, but maybe his connection was toxic… And he wanted so badly to get away from the love-drinking vampirism of his hive…
Fighting his heart, Thorax slipped off in the confusion before anybody could realize he was leaving, trying to ignore the part of his brain screaming that he needed to stay with Pharynx, please him, serve him. For once, Thorax thought maybe he was free from his big brother’s dominating control over his whole being, even though he ached to return every day.
***
When Thorax did return to the hive after so long, he kept his own extra anxieties secret from his pony friends. How could they understand what he was feeling? The bubbling combination of fear and love, for his own brother, nonetheless…
Thorax was incredibly relieved not to run into Pharynx while the mission was ongoing. He knew, in any form, he would have submitted instantly once he met his brother - he would have been so ashamed if his friends had seen him that way, grovelling at his brother’s hooves and begging for his cock.
And then when he transformed, Thorax felt certain this would herald a new stage in their relationship - a thought that at once pleased him and terrified him. Did he really want to be Pharynx’s equal? His… superior, even? The submissive changeling was uncomfortable with authority, but now he was the hive’s leader, it seemed, and it seemed like that would have to extend to Pharynx too, right?
Pharynx finally returned a day later, looking exhausted. He’d been on patrol again, scouting the whole area diligently as he heard warning of an incoming attack… Unfortunately for him, he’d flown around exactly in the area where Thorax and his group had been before, and were no longer.
“What. Happened?” he snarled, storming up to the tallest changeling in the middle of the room, glaring and buzzing his wings at the others. “You all look like prissy, pathetic, ponies!”
Pharynx stomped his hoof and several changelings jumped back in alarm, before someone piped up:
“Thorax taught us we don’t need to t-take love to survive… We can live off of GIVING love!”
Pharynx was so surprised by the mention of his baby brother, he didn’t protest that statement, although he felt it was ridiculous. Instead, he narrowed his eyes, trying to make sense of Thorax being mentioned, scowling as he slowly turned to face the tall green changeling in front of him.
“Thorax?!” he hissed, glaring as he hovered upwards to look his brother in the eye. “Is that really you?”
“O-oh, hey, Pharynx,” Thorax said, trying to hide the panic in his voice. “L-long time no see!”
Pharynx didn’t say anything. Instead, he socked Thorax hard in the face, sending him tumbling to the ground, looking furious as he stared down at his brother again.
“You abandoned our hive! You’re not a leader. You’re a TRAITOR!” he spat, turning around and buzzing away from Thorax, who groaned as he rubbed the bruise he was developing around his eye.
“Should I go after him, King Thorax?” one changeling asked, as they peered down the tunnel Pharynx had taken.
“N-no,” Thorax said, bowing his head with shame. “I’ll… I’ll fix it, myself.”
***
Despite his new, taller physique, Thorax still trembled as he crept into the cave his brother was resting in. He had some kind of power over him - even now, he felt cowed, submissive in his very presence.
“Hello, little brother,” Pharynx hissed, without even turning around to look at him. “Come to try and talk some pony grubshit into my head, too?”
“N-no! I mean,” Thorax floundered as Pharynx turned to look at him, those purple eyes glowering right at him. “It’s not… it’s not grub… it’s true, Pharynx, you saw everybody else…”
“I see you too,” Pharynx said, rising to his hooves. “And you’re a traitor and a false king. You aren’t fit to lead us.”
Thorax swallowed, trembling, but willing himself to stand up for himself.
“Why would you say something like that, Pharynx?” Thorax said, frowning. “I defeated Chrysalis. And, I helped the rest of the hive with their metamorphosis… so if you could jus-”
“That’s not how I hear it,” Pharynx interrupted, sneering. “I hear you got your little pony friends to do all the dirty work for you.”
Thorax tried not to shrink back from the accusation, but before he could say anything, Pharynx went on.
“And I say it… because we both know what your real place is, Thorax.”
A beat. Thorax licked his dry lips, as Pharynx continued, his voice dangerously low and his grin all fangs.
“Underneath me, being pounded into the dirt of this hive as I claim you for my own, isn’t that right?” Pharynx growled, stepping towards Thorax. “You may have the rest of the hive fooled, but I know what you really are - a pathetic little eggdump who isn’t fit for anything except being bred and used.”
Thorax felt himself getting dizzy, feeling sick and aroused all at once. He’d thought things would change between him and Pharynx, but the shorter, more aggressive changeling was dominating him as easily as ever. Thorax gulped, shaking his head, both to say ‘no’ and to clear of the lewd thoughts beginning to cloud his mind.
“Y-you’re wrong, Pharynx,” Thorax said, hesitantly. “I’m a good leader… Look how I’ve changed…”
“Yeah, like I said. You look ridiculous - like those loser pony friends of yours.”
Thorax frowned. Buoyed by his newfound confidence after making several true friends, he wasn’t about to take a comment like that lying down, as much as he hated confrontation.
“Pharynx, stop! You… you don’t understand yet, but Spike… and all my other friends… they’re really great!” Thorax smiled uneasily. “And they’re strong, too! P-powerful…”
Thorax trailed off. Pharynx had sat on his haunches, and was smirking cockily, eyes narrowed - but Thorax wasn’t looking at his face. Between Pharynx’s legs, his long, thick ovipositor slowly slithered out, pulsing in the cool air.
“Maybe so,” he said, with a smirk. “...But you’d trade them all for one taste of me, wouldn’t you?”
“N-no!” Thorax said, but he didn’t sound certain.
“Come on, Thorax,” Pharynx hissed. “I’m doing this… out of love. You’ll always be my brother. I may not respect you as a leader, but I can’t stand to see you so...needy.”
As he spoke that last word, Pharynx leaned in, stroking a chitinous hoof along Thorax’s back-plating, feeling him shudder and suppress a moan in response. Thorax closed his eyes, his face a picture of the inner tension inside him, rooted to the spot as he tried to stop himself from going back to this, submitting to his brother once more.
“I think my ovipositor was the real reason you came back, wasn’t it?” Pharynx continued. “You wanted… needed to feel it inside you, just one more time?”
“N...no,” Thorax replied, but it was a much weaker protest this time. He’d come here to help his friends - but he’d be lying if he said he hadn’t been thinking about Pharynx plunging into his body again and again while they were apart…
And he knew, those fears about Pharynx catching them had been tinged with a sickening arousal, at the idea of him finally being exposed for the worthless whore he was, powerless to do anything but moan with lust as he was defiled and degraded in front of his new friends.
“Just admit it, Thorax,” Pharynx growled, circling his younger brother. Somehow Thorax still felt smaller, weaker, despite his transformation. “I can smell the stink of lust coming off of you. You want this. Admit you only came back for the chance to worship my shaft and maybe… I’ll let you.”
“Pharynx… please,” Thorax started, unsure what he was pleading for. The temperature in this part of the hive seemed to have risen by a hundred degrees since he entered, and he was starting to think maybe it was a bad idea to come alone… It made it harder to not give in to temptation.
“I can.. Practically taste how bad you want this,” Pharynx whispered in Thorax’s ear.
“Oh Chrys- Cel… Oh Pharynx!” Thorax moaned, squeezing his eyes shut, pawing the floor as his wings flared from under his carapace indecisively.
Time seemed to stretch on and on, as Thorax fought with himself, knowing he should leave, but not able to bring himself to move.
“Ph-Pharynx… please,” Thorax groaned. “M-mount me! Fuck me, I need it! Oh, please, please, I need to feel you inside…”
“Crouch down, slut,” Pharynx ordered. “Show me how bad you want this.”
Instantly, Thorax dropped his haunches low to the floor, screwing his eyes shut with humiliation… and need. He felt Pharynx mount him again, and he sighed at the familiar feeling, biting his lip as he pushed his rump high in the air, trying to meet Pharynx’s crotch. He was more slender now, more tapered, and with a whimper as Pharynx’s ovipositor slowly teased at his entrance, he realized the new changes in him would make this penetration a tight fit.
If Pharynx realised or cared about that, he didn’t show it. With forceful lust bordering on anger, Pharynx’s hips shunted forwards, and Thorax gasped and panted, gritting his teeth as he was thoroughly stretched open by his brother’s shaft. It felt at once alien and familiar, being claimed again by his big brother, with his new, more slender body… He moaned despite the pain of his hole being forcefully opened so wide, feeling Pharynx behind him, spreading his hooves so he could plunge slowly in and out with agonizing finesse.
“Tell me why you came back, Thorax,” Pharynx demanded, his voice even and cool as he worked that throbbing great plunger in and out of his brother’s poor hole, stretched taut around him. “It was because you need this, wasn’t it?”
“Y-yes,” Thorax replied, weakly, moaning in shame and lust. “I b-belong under your hooves, brother!”
Pharynx snarled with satisfaction as he shoved his length hard back inside Thorax’s muscular tightness, eliciting a strained-sounding squelch and an equally strained squeal from the changeling he was rutting. His hooves dug into Thorax’s sides as he roughly pounded the taller changeling like he’d never done before, unleashing his anger, betrayal, and love, all at once, on the pathetic specimen that dared to come crawling back to him.
“You a-are so far below me,” Pharynx hissed, angrily. “You’re below even the dirt my hooves walk on.”
Thorax nodded, panting desperately as his needy hole was forcefully filled over and over, his own ovipositor throbbing below him from the sheer passion of Pharynx’s perverted breeding. Thorax would have responded verbally, but before he could he felt one of Pharynx’s hooves smash into the back of his head painfully, forcing his head down.
“Wor-worship it, slut! Worship the ground my hooves have touched!”
Thorax complied instantly, not even questioning the act of obedience, mindlessly serving the dominant changeling who was thrusting into him again, delivering to new peaks of ecstacy… and new depths of depravity. With his slender neck bent low to the ground, Thorax kissed and nuzzled the dirt as if it were something precious, running his tongue over the grooves the hard edges of Pharynx’s hooves had left.
“Ngghh… good little f-fuck toy!” Pharynx hissed, mockingly. “How do you think everybody else would feel if they could see their new leader now?”
Thorax moaned and thrashed slightly, gritting his teeth. The idea of such a humiliation tugged at his libido, but also filled him with horror.
“They’d know what I know th-then, wouldn’t -NGH!’ they? You’re not a real leader… You’re a worthless shaftsleeve…”
Thorax groaned, teetering on the edge of fantasy, feeling himself being dragged into Pharynx’s dark world, one where he controlled Thorax, and Thorax loved it that way. The eager thrusting into his hole was getting faster, more intense now, as Pharynx insisted on hilting in Thorax’s already-stretched passage again and again.
“I-if you want my cum… b-beg for it,” Pharynx hissed, feeling his little brother tensing around him, sensing the mood in the air. “Or I’ll p-pull -GNR- out, and finish on the floor. It’s more worthy of my seed than you are…”
Desperately, Thorax, gasped, thrusting his rear urgently back against Pharynx’s invading length, shuddering at the way it plunged so deeply inside his tight, sensitive canal. He needed that shaft inside him, needed to feel Pharynx’s hot fluid spilling into his passage.
“Pharynx, please, please, cum insi-inside me!” Thorax moaned, feeling the thrusts getting more erratic and forceful now. “Please mark me with your hot ooze, l-let everybody see I’m n-not a leader, I’m just your f-fuck toy!”
Pharynx hissed in pleasure, his thrusts cruel and forceful as he shoved his swollen tube in and out of Thorax, grunting and thrusting as hard as he could as Thorax wailed softly in a mixture of bliss and pain, hungry for his oozing fluid to fill him completely…
“Gahh! Ngghhh! OHHH!” Thorax came hard, firing brightly-colored slime onto the floor, panting and gasping as his hole clenched around his big brother at the very instant Pharynx began to cum inside him.
Thorax moaned, his world full of lights and bliss and shame, his cries suddenly rising an octave as Pharynx yanked his throbbing length hard out of his hole, spurting it all over his backside, several spurts oozing down his flank, marking him completely. He whimpered, his rear empty as his orgasm slowly ebbed away, feeling Pharynx’s cum burn into his chitin, as if he’d be forever stained by it.
“Slut,” Pharynx said, roughly, kicking the dirt. “Be back tomorrow so I can make up for lost time.”
His breathing was ragged, but he was trying to compose himself as he flew towards the exit - unlike Thorax, who lay in a crumpled heap on the floor, sticky ooze coating his body as he panted, breathless.
“Oh,” Pharynx added, as he turned back one last time. “And clean up the mess. I want all of my fluids inside you, one way or another.”
“Y-yes, sir,” Thorax replied, weakly, as he shuffled backwards slightly, clearing the thick, pungent slime off of the spongy, dirty floor with his tongue.
***
Looking back, Thorax could see he should never have gone to see his brother alone. Perhaps if he’d played the role of leader around him, things might have been different. But from that moment on, all Pharynx had to do was smirk the right way, or raise an eyebrow, and Thorax was trembling putty in his hooves.
Night after night, Thorax tried to persuade Pharynx of the virtues of their new lifestyle, trying to convince him his way was better… Of course, that convincing usually happened while he was underneath Pharynx, moaning his name, and usually ended with him blurting out how he was no leader, just a cumbucket for his own big brother.
“Ngh… Pharynx,” Thorax panted on one such occasion, as Pharynx heedlessly thrust his slimy shaft up into him. “Y-you should… ngh… come to the F-Feelings Forum sometime.”
“Oh yeah,” Pharynx said, smirking. “What feelings should I -GNH!- talk about? How good your tight hole feels around my ovipositor?”
“N-no, that’s not…”
“How ashamed I am to have to pretend a pathetic little -ngh!- weakling like you is the king? How hilarious it is that everybody e-else really thinks you’re anything more than a HOLE for a superior changeling to FUCK?”
Pharynx was really giving it to Thorax hard now, and soon he found he couldn’t even think about official business, mind swirling in a haze of pleasure and plunging, throbbing organs invading him over and over until he squirted his own load on the floor, furious at himself for allowing the… distraction, once again.
Over time, and no thanks to Pharynx, Thorax became a better leader, learning to be more assertive from his new friend, Ember, and getting more practice at dealing with the pressures of being king. Implementing more ideas from pony society helped keep everybody happy, and soon Thorax was proud to say he was leader of a hive of reformed changelings… All except one, of course.
That only made it more shameful when he was crouched down, face in the dirt, moaning with pleasure as his brother used him as a cheap sex toy. He was addicted to the feeling of his brother’s shaft inside him. Externally, Pharynx acted more and more erratically, aggressive, even, like there was a deep, hungry need to dominate inside him.
He released those frustrations every evening, sometimes in the day, sometimes both, on Thorax’s poor, abused hole, and Thorax often ended up speaking in a whisper with a hoarse voice the day after, worn out from crying out in passion. Pharynx’s domination was so complete, Thorax knew even if he’d wanted to say no, there would have been no chance of refusing his big brother.
Thorax didn’t know what to do - it wasn’t until a few months later, when his pony friends came to visit, that things would change again...
Months later, Thorax and Pharynx found themselves facing the maulwurf, together, working as a team.
Thorax couldn’t believe how great it felt to fight alongside his brother for once - instead of against him. For once, the whole swarm was behind Pharynx, and Thorax couldn’t have been prouder.
When he finally transformed, it seemed like his love for the hive had changed him at last - changed his outside, at least… But Thorax gulped as he wondered if he was still the same on the inside...
As the celebration ended, Thorax felt Pharynx’s hoof on his shoulder.
“Don’t think this has made anything different between us,” he said, smirking. “I’ll see you tonight…”
Thorax swallowed as he watched his brother off towards another group of changelings who were calling him over, smiling as he was part of the hive again.
***
Pharynx found him later that evening. Thorax had just finished talking to a group of changelings about his plans for creating a new changeling patrol, with Pharynx at the head. Every changeling around could feel the pride swelling in his chest, palpable, so obviously pleased that his brother was finally supporting the swarm instead of trying to ruin things.
Walking alone down one corridor, Thorax hummed a happy tune he’d learned from his pony friends - and then stopped, sensing somebody behind him.
“Pharynx!” Thorax beamed, as he turned around. “I was just talking to Ex...o ...about you…”
Thorax trailed off. Pharynx was wearing a cocky smirk, and he walked forwards - revealing the enormous black ovipositor dangling beneath him. Thorax swallowed. His brother was somehow even more enormous now, and it made his knees weak with lust as well as fear.
“We both know you want this,” Pharynx said, grinning. “So submit, and I’ll fuck you like you need.”
Thorax glanced towards the thin walls of the hive, the entrance that Pharynx had come in through. He knew there was no way he could have sex with Pharynx here without the swarm hearing them.
“N-not here,” he said, nervously, turning to head deeper into the hive. “Somewhere more private.”
Thorax felt Pharynx’s hoof stopping him, spinning him back around. Now the older changeling was almost exactly the same height as Thorax, and he easily pressed their lips together, fangs lingering on the lower one as he pulled away. Thorax trembled from the shamelessness of doing that right there, swallowing, realizing his brother meant to take him there - wanted the rest of the swarm to know exactly what a slut their King was for his own big brother.
There was something else, too. Usually Pharynx’s emotions were hidden behind a veil, a thick skin like the exoskeleton that protected the changeling’s bodies. But now Thorax could taste them all, a rich mixture of flavors that left him dizzy.
There was confidence there, a lot of it, Pharynx utterly certain that his brother would soon be submitting to him, and it made Thorax’s knees weak, believing it more and more himself. Thorax also detected love, although he’d always known his brother loved him, really. That love was part of why Pharynx dominated him this way, knowing how badly his little brother craved being owned and fucked until he could barely walk.
Overwhelmingly, though, Thorax could sense Pharynx’s powerful lust for his brother, the way his body wanted to cling to his and claim him, with his say so or not. As Pharynx grinned wider, narrowing his eyes, Thorax gulped, knowing he had no defenses against the sheer animal arousal of his brother.
“W-we can’t,” Thorax replied, weakly. “The others-”
“I want them to hear,” Pharynx interrupted, smirking. “I want them all to know exactly what their King is like. They deserve to hear the shameless noises you make, too.”
Thorax had no response, trembling with indecision, licking his lips as his ears lay back. Pharynx’s wings buzzed, and he flew around behind Thorax, always one for action more than words. Thorax gasped as he felt his brother’s new, heavier weight on his back, mounting him more easily now.
“Look, you don’t have to crouch anymore,” Pharynx murmured, amused. “...But I can’t promise you won’t end up falling to your knees.”
He nipped Thorax’s ear, and the King moaned, pressing his rump back wantonly as the thin rod between his legs slid out, throbbing. He could feel the head from Pharynx’s own ovipositor, slimy and warm as it was rubbed between his legs. Thorax’s heart stopped - it was bigger, so much bigger now. He wasn’t sure he could even take it, but another part of him demanded he submit, needing to be filled by the even-more-impressive length and take his brother’s loads.
“Y-you’ve changed,” Thorax said, breathlessly, feeling how far back Pharynx had to pull his hips just to line himself up with Thorax’s tight hole. “S-so big!”
“I have… you don’t even know how much,” Pharynx said, cryptically - but before Thorax could ask what he meant, he felt his tip prodding forwards against his entrance.
Hyperventilating, he trembled, grateful for Pharynx’s forehooves clasped around his waist, holding him in place. He let out a gasp, feeling the pressure increase, holding onto the last few moments of being the ‘King’ to his swarm, and not just Pharynx’s fucktoy.
Thorax was so horribly ashamed of what he’d become, of how obediently he allowed the other male to dominate him, of how much he craved it.
He was also hornier than he’d ever been in his life, and the conflict showed in the first lust-filled moan he let out as he was penetrated, the end of Pharynx’s enormous shaft forcing into his backpassage after several long, agonizing moments of feeling the pressure increase, his body finally giving in.
“AHHH! OH! SO… HUGE!” Thorax yelled, his green cheeks firey red as he stomped a hoof on the ground, panting, trying to endure the massive penetration as it stretched his hole beyond belief.
Pharynx just kept plunging deeper, feeling that ring of tautness around his invading member like a steel band, clenching furiously not because Thorax was trying to deny him entry, but because he was just that big now. Thorax cried out, whipping his head around frantically as the absurdly large shaft sank deeper and deeper into his guts, eyes rolling back in his head from the sheer overwhelmingness of just feeling something so huge moving inside him, stretching him open.
“I know you need this, you slut,” Pharynx snarled, jabbing his hips forwards and provoking an ear-splitting screech from the changeling King. “You need to be brought LOW… reminded of your place….”
They could both hear the buzzing of wings as the swarm detected a commotion, heard their King crying out, possibly for help… and then the shocked gasps and retreats as they came closer, sensing the nature of the cries, love and lust and pain rolling off of their King, who wallowed in his shameful sluttiness as he was fucked by his own brother.
Thorax whimpered, ears back, squeezing his eyes closed, knowing everyone knew now what was happening. The gossip would travel fast, and by morning, he wouldn’t even be able to look his subjects in the eye, knowing they were all aware now that he was his brother’s willing broodslut.
And still, all he could do was moan, throwing his head back as he felt that enormous hardness begin to work back and forth inside him, churning his guts with insistent shoving and tugging back and forth. His cries of pained pleasure reverberated off the walls of the hive, as Pharynx grunted rhythmically, pumping his slimy ovipositor in and out of his little brother’s backpassage.
“I’m g-going to fill you with my young,” Pharynx snarled. “Then everybody in the swarm will see your true place - underneath a real male, taking his loads, baring his brood…”
“Ohh! Please, Pharynx!” Thorax begged, hazily unsure if that was a real claim, or if Pharynx was bluffing, but so aroused he didn’t care, panting eagerly as he shoved himself back against the huge length that was shoved right up inside him again and again.
“You need it, don’t you,” Pharynx said, demanding a response with every harsh thrust of his hips that rammed his ovipositor deep into Thorax with a loud squelch. “Tell your big brother how much you want to be filled with his eggs, stomach swollen with my brood…”
“PLEASE! I’m your slu-slut, I need to carry your eggs, impregnate me, oh, please, please Thorax!” he cried out, full of shame but taking the plunge now, his body seized by the bliss of being rutted so hard by something so big.
He needed it, craved being defiled and used by his brother in the ultimate way, his own ovipositor quivering as he was fucked hard towards his peak… And towards his fate as an incubator for his brother’s clutch.
The gargantuan length inside him seemed to be swelling bigger and bigger, as Pharynx growled and snarled, his deep voice rumbling in the back of his throat as he pounded Thorax, gripping him, clinging, ready to fill him, claim him, deeper than he ever had been before… With a sudden roar, Pharynx slammed his length home, poking it as deep in as it could go… and began to unload.
Thorax shuddered, eyes wide as time seemed to stop, feeling first that gush of familiar warmth inside him… and then something else, a hard, oval-shaped lump, stretching the walls of Thorax’s ovipositor, and his own well-used passage. As he felt the first egg being deposited deep inside him, Thorax came, thrashing and moaning as his brother latched on, grunting each time he pumped another of his clutch into his baby brother.
Thorax moaned with shame and bliss as he felt Pharynx’s shaft holding firm inside him, the only motion the waves of ripples travelling up along it as gelatinous egg after gelatinous egg was squeezed up and out by powerful spasms, pushing deep inside of Thorax.
Thorax was beginning to feel full now, but they kept coming, more and more, swelling his stomach, stretching him out. He whimpered weakly, but Pharynx merely hung on tight, making sure to implant every last egg inside the warmth of his brother. Finally, he shuddered, releasing one last drop of ooze… and then aggressively dragging his length out of Thorax.
“AH!” Thorax yelped, feeling the harsh withdrawal from his tender, well-used backpassage. He could feel the eggs pulsing slightly inside him, and he wobbled woozily, aware he was now full of his brother’s young, feeling how the sheer mass inside made his tummy bulge dramatically. He lay down on his side, squeezing his eyes shut, not sure if he was more full of shame or lust over this new situation.
“I’ll go tell the rest of the hive to prepare an area for you to lay in,” Pharynx sneered, as he looked down at his ruined brother, moaning, collapsed, panting on his side, stomach swollen with eggs. “They should know you’ve been impregnated.”
Thorax weakly opened his mouth to protest, but Pharynx was already gone - and by the cheer that Thorax heard a few moments later, he’d already told them.
Now he was his brother’s breeding slut - and everybody knew it. Thorax gulped as he stroked his stomach, full of his brother’s clutch. They’d grow inside him for a few days, incubating and being nourished by him, until he laid them in a nest prepared for the occasion. They would certainly be bigger going out than coming in - Thorax winced just imagining how stretched he’d feel when that happened…
***
“The King doesn’t want to be disturbed! Leave him alone.”
Thorax could hear his brother giving orders to the rest of the swarm. Pharynx had been taking over more and more of his duties lately. Thorax was grateful for that, but he was a little worried… he was supposed to be King, but lately he didn’t feel like a leader at all, just a container for his brother’s eggs…
Speaking of which… Thorax groaned as he got clumsily to his hooves. He could barely walk, belly bulging with eggs. He could feel his muscles churning, moving the clutch into position for laying, lining up inside him… With a gasp, he felt them clench, urging him to push his precious load out into a waiting nest.
“PH-Pharynx!” Thorax called, with a groan. “Is the nursery hive ready?”
Pharynx’s head poked into the cavern where Thorax stood, wincing and trembling as more spasms racked his body.
“You’re ready to lay my brood, little brother?”
“Y-yes!” Thorax replied, urgently. “I can’t hold it back much longer.”
“This way,” Pharynx said decisively, leading Thorax to the nest.
There was no hope of the king flying there… Thorax merely stumbled along as quickly as possible, his stomach aching, feeling his muscles contracting desperately as they tried to make him expel the eggs inside. Various changelings bowed as he passed, eyes wide as they stared at his swollen stomach, knowing what was inside.
Thorax managed a weak smile at some of them as he hurried - relatively speaking,- past them. As he finally reached the nursery, he was quivering all over, racked with contractions. Pharynx grunted his approval as Thorax entered the centre of the room, a small hollow dug and lined with fresh grass and flowers, bound together with the sticky dried saliva of other changelings. Thorax had to smile at the flowers - his brother could be a brute, but at least he cared…
“NGhh… It’s coming!” Thorax announced, lowering himself to allow the first egg to exit his body.
He grunted and strained, feeling some of the mucus that lubricated his passage dribble out, onto the waiting nest. Moaning, Thorax squeezed his eyes shut, trembling, as he felt his body convulse, his hole stretching first a little - and then spreading more and more, the band of muscle forced open wide as the long, semi-transluscent egg was slowly expelled.
At the widest point, Thorax gasped, panting with pain, but also a unique, almost orgasmic kind of pleasure, swollen with eggs and being rewarded for bringing them into the world… With a final cry, he forced out the first egg, laying it in the nest, panting, as a wave of sheer pleasure rocked his body.
He didn’t have long to enjoy it, though. A few seconds later, and he felt his body trembling, the second egg sliding into position, trying to follow its sister out of Thorax’s gaping passage. He lowered his haunches once more, and grunted, feeling the muscles of his inner walls squeezing, pushing the egg to its exit.
When Queen Chrysalis had done this, she’d laid the eggs far apart, some stuck on walls or high up to represent differences in rank - Thorax didn’t understand it clearly, but the temperature difference supposedly created physiological differences in the grubs, making sure they grew into what they were assigned.
Maybe instinct had driven her to do it that way, or it had been her choice. Whatever the reason, Thorax’s instincts told him to lay the clutch close together, nestled in the same bed, warming one another slowly as the grubs grew inside. He gasped as he suddenly felt the second egg stretching his entrance, dropping beside the first.
Tears were in his eyes now, as he constantly convulsed and pushed, his muscles straining around egg after egg, his stomach growing less swollen but still aching as it was slowly emptied. Every time he pushed a slimy larval egg out of himself, Thorax moaned and rolled his hips, panting as he was gripped by new pleasure… that soon died down as another new egg took the place of the previous one, his body urging him to eject it into the nest with the others.
“AHhhh,” Thorax whimpered, gritting his teeth as he came to the last egg.
Perhaps it had been forced to the end because it was so very large, because it was huge. Thorax was almost afraid it would rip him open, his body quaking violently as he tried to spread himself wide enough to expel it.
Thorax’s heart pounded like a bass drum as the tip of it slowly began to poke out… and then, with a guttural shriek, he bore down hard, the last egg squirting out of his body. Powerful tremors ran through him, and he moaned, gasping, shuddering as he orgasmed… before stumbling backwards out of the nest, falling onto his belly, looking at the iridescent eggs he’d laid with a strange feeling of pride.
Unlike the ones Chrysalis had laid, Thorax’s eggs were shiny and brightly colored, a rainbow that flickered in the light. Through the shells, he could make out the shapes of little grubs inside.
“Are you done?” Pharynx asked, having walked up behind Thorax without him noticing.
“Y-yes, I think so,” Thorax replied, smiling, dazed from orgasm and trembling with pleasure.
Pharynx lay down beside him, looking at the clutch of eggs. The corner of his mouth turned up in a smile, and he nuzzled Thorax with surprising tenderness.
“Nice job,” Pharynx said, gruffly. “...You better be ready for tomorrow, because I think we should start working on more as soon as possible.”
Thorax’s ears shot up, as he realised Pharynx’s intent - to breed him constantly, over and over, his role no longer the king, but his brother’s slut, days devoted to being fucked and bred and laying more and more eggs. Like Pharynx had always said, his only job would be being bred and used by a more virile male, while Pharynx become respected as the true leader, Thorax humiliated and panting in the background, full of his brother’s cum and eggs…
And despite the foreboding in his stomach… Thorax found himself loving the idea of finally embracing his place, permanently.
