A Slave for Love

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.
