I used NovelAI's unlimited gen membership for $25 a month. Note that "unlimited" is kind of a lie, it's only unlimited if you're under a certain resolution and only if you're not using any of the advanced features. Upscaling and other features cost the on-site currency, which the membership gets you 10000 a month. That should be more than enough for a month, but you can burn through it quickly since NAI gens so quickly.

The noon sun beat down on Ponyville, baking the dirt streets until the air shimmered with heat. Inside their clubhouse, the Cutie Mark Crusaders were melting. Apple Bloom fanned herself with a leaflet she'd swiped from the town hall. "It's hotter than a hornet's nest in a bonnet out there."

Sweetie Belle, lying limp on the floor, groaned. "My horn feels like it's going to melt off."

Scootaloo kicked a discarded helmet across the room. "This is the worst day for crusading ever. We've tried everything. Basket weaving, stamp collecting, professional napping... nothing sticks."

A silence fell over the clubhouse, thick and heavy as the summer air. They'd had the same argument, or a variation of it, a hundred times. The quest for their cutie marks felt like a story everypony else in town knew how to read, but they were still stuck on the cover.

Then, a thought, so audacious it made the dust motes dance in the shafts of light. Apple Bloom sat up, her little bow twitching. "What if... what if we're lookin' in the wrong barns altogether?"

Scootaloo stopped kicking. "What do you mean?"

"Think about it," Apple Bloom said, her voice dropping to a conspiratorial whisper. "We've been tryin' all the same things. The things ponies *talk* about. But what about the stuff they don't?"

Sweetie Belle propped herself up on her elbows. "Like... what?"

Apple Bloom looked from one friend to the other, a strange, uncertain determination in her eyes. "Like... the stuff my brother and Big Macintosh talk about when they think I'm asleep. The stuff the older colts snicker about by the fence. About... mares. And... services."

Scootaloo's wings buzzed, not from excitement, but from a jolt of something new and dangerous. "You don't mean..."

"Maybe that's it!" Sweetie Belle squeaked, her eyes wide. "Our special talent isn't something we *do* with our hooves or voices, but something... for others! Something stallions would really, really appreciate!"

The idea hung in the stuffy clubhouse. It was scary. It was weird. It was utterly unlike anything they had ever considered. And for that very reason, it felt like the most promising lead they had ever had.

They looked at each other, a silent pact passing between them. This wasn't basket weaving. This was a real crusade.
***
Their first target was Bulk Biceps, grunting away at the Ponyville gym. He was always friendly, always eager to help, and he had a certain... reputation. The trio approached him after he'd finished a particularly thunderous set of fly-ups.

"Uh, excuse me, Bulk Biceps?" Apple Bloom started, her voice trembling slightly.

The massive white pegasus turned, wiping a sheen of sweat from his brow. "YEAH?"

"We were wondering," Sweetie Belle picked up, her voice a silken thread, "if you might need some... assistance. With anything. At all."

Scootaloo struck a pose she hoped looked cool and alluring. "We're very... versatile."

Bulk Biceps blinked, then a slow grin spread across his face. "YEAH! COULD USE A... COOL DOWN." He led them into the private shower area in the back, a steamy, tiled space that smelled of iron and soap. He leaned against the wall, flexing. "SO. WHAT'D YOU HAVE IN MIND?"

The crusaders looked at each other. This was it. They had to improvise. "Well," Apple Bloom began, stepping forward, "we heard that some... specialized massages can really help with muscle recovery."

She reached out with a hoof and experimentally traced the line of a vein on his bicep. Bulk Biceps shuddered. "Oooh. YEAH." Scootaloo and Sweetie Belle joined in, their small hooves finding the knots and tensions in his powerful frame. They worked in silence for a moment, the only sounds the drip of water and the stallion's increasingly heavy breathing.

The situation escalated with alarming speed. Their innocent explorations, guided by whispered half-truths and wild guesses, began to elicit a very specific, very powerful reaction. Bulk Biceps's breathing grew ragged as their hooves danced across his twitching muscles. The massive pegasus grunted, his eyes rolling back slightly as a visible tremor ran through his powerful frame.

"WHOAH," he groaned, and suddenly the reason for his reputation became terrifyingly apparent.

A thick, veined shaft began emerging from its sheath, growing with every heartbeat. It was enormous—a pillar of flesh that seemed impossibly large for any pony, let alone a normal pegasus. The head was flushed a deep purple, already glistening with a clear fluid that dripped steadily onto the tiled floor. Beneath it hung a pair of testicles that looked like heavy leather bags filled with river stones, swaying with every slight movement Bulk Biceps made.

The Crusaders froze, their eyes wide. The whispered rumors in the schoolyard hadn't prepared them for this reality.

"YEAH," Bulk Biceps grunted, his voice thick with need. "KEEP... GOING."

Apple Bloom swallowed hard but stepped forward first. She placed both hooves on the shaft, which felt hot and alive beneath her touch. It throbbed with his heartbeat, the veins pulsing against her fur. Sweetie Belle and Scootaloo joined in, their smaller hooves barely making it around half the circumference. They worked awkwardly at first, their movements clumsy and uncertain, guided only by fragmented rumors and wild guesses.

Bulk Biceps's breath came in ragged gasps now, his massive chest heaving. The muscles in his thighs and abdomen tensed as the fillies continued their inexperienced ministrations. The head of his penis swelled further, the clear fluid now flowing freely down the shaft, coating their hooves in slippery wetness.

"Closer," he grunted, his voice strained. "ALL OF YOU."

They hesitated, then obeyed, pressing their bodies against his twitching muscles. The air in the steamy shower grew thick with the musky scent of his arousal.

The explosion caught them completely by surprise. With a roar that echoed off the tiled walls, Bulk Biceps released. The first shot of thick, white semen arced through the air and splattered against the opposite wall with enough force to make a sound. Then came another, and another. The sheer volume was astounding—it seemed impossible that any creature could produce so much fluid.

Scootaloo was the first to be hit directly. A rope of cum caught her across the chest and face, knocking her backward slightly. Sweetie Belle gasped as a warm stream splashed against her flank, running down her legs in sticky rivulets. Apple Bloom yelped as the final spurts coated her bow and mane in thick goo.

The three fillies stood in a daze when it was over, shivering slightly despite the steamy heat. They were soaked from head to hoof in what felt like gallons of semen. It dripped from their ears, ran down their faces, and coated their bodies in thick layers. The floor was a mess of puddles, the wall splattered with evidence of Bulk Biceps's release.

Through the haze of fluid covering her eyes, Sweetie Belle noticed something new on Bulk Biceps's flank—a dumbbell cutie mark, shimmering into existence as if summoned by his climax.

Their own flanks, however, remained stubbornly, disappointingly blank.

***
They didn't give up. One stallion led to another. They tried their newfound "skill" on Braeburn at the orchard, the muscular earth pony leaning against an apple tree as the fillies took turns exploring every curve and ridge of his hardened body. His southern drawl turned to husky gasps as Apple Bloom's small tongue traced patterns across his chest while Sweetie Belle and Scootaloo worked together below, their coordinated efforts culminating in a spray of sticky warmth that splattered across their faces and chests. Yet their flanks remained stubbornly blank.

Then came Fancy Pants at a garden party, his sophisticated facade crumbling under the fillies' innocent experimentation. Hidden behind a row of rose bushes, the wealthy unicorn found himself surrounded by eager young mouths and hooves. Sweetie Belle discovered how sensitive a horn could be to gentle licks, while Scootaloo learned the magic of fluttering wings against certain sensitive areas. When Fancy Pants finally shuddered and released, his elegant monocle fell to the ground, splattered with evidence of their efforts. Still, no cutie marks appeared.

Next was the mail pony Derpy's cousin who was visiting from Canterlot, a stallion with unusual endurance. He introduced them to positions they'd never imagined, guiding their small bodies with surprising gentleness. Apple Bloom found herself upside down against a wall, her bow askew and dripping, while Sweetie Belle discovered the peculiar taste of a stallion's excitement mixed with mailbag dust. Scootaloo's wings became coated in layers of drying fluid as she learned how to use them to enhance their "services." By the time he finally finished, all three were practically unrecognizable under layers of pearlescent evidence, yet their destinies remained unrevealed.

The crusade continued through Ponyville. They visited the baker early one morning, helping him "knead" his dough in new and creative ways. The librarian found them in the restricted section, where they "studied" ancient texts on stallion physiology through practical application. Even the school janitor wasn't spared his turn behind the bleachers. Each encounter was a whirlwind of nerves and fumbling, a desperate attempt to unlock their destiny. They got better at it, their coordination improving, their understanding of stallion anatomy growing. Apple Bloom developed a special technique with her tongue that made unicorns' horns sparkle, Sweetie Belle learned to harmonize her moans to match a stallion's rhythm, and Scootaloo mastered the art of using her wings to enhance their joint efforts. Still, no cutie marks.

They were gathered behind the schoolhouse, disheveled and discouraged, sticky with the failures of the afternoon. "This isn't working!" Sweetie Belle wailed, a glob of pearly white dripping from her ear. "We're covered in... well, *this*... and we're still blank flanks!"

Apple Bloom wiped away a thick strand from her bow. "We must've tried it on nearly every stallion in Ponyville by now. What are we doin' wrong?"

Scootaloo shook her head, sending droplets flying. "Maybe our special talent isn't just servicing one stallion at a time. Maybe we need to... go bigger."

The sun was setting, painting the sky in shades of orange and purple as they approached the Ponyville town square. In the center, the statue of the town founder stood proudly. Around it, a crowd had gathered for an impromptu end-of-summer celebration. Music played, cider flowed, and ponies laughed. It was perfect.

The Cutie Mark Crusaders, now veterans of their strange crusade, moved with a new kind of confidence. They climbed onto the raised platform around the statue's base. Apple Bloom stood front and center, a determined glint in her eye. "Fillies and gentlecolts!" she called out, her voice amplified by the strange acoustics of the square.

Everypony turned. The music stopped.

"We are the Cutie Mark Crusaders!" Sweetie Belle declared. "And we have discovered our true purpose!"

Scootaloo grinned, a predatory glint in her eye. "We're here to offer our services to every stallion in Ponyville! All at once! For our cutie marks!"

A wave of stunned silence washed over the crowd, followed by a confused murmur. Then, a big, burly earth pony from the construction crew, one they hadn't gotten to yet, let out a booming laugh. "Well, I'll be! Why not?" He stepped forward.

That was all it took. Like a dam breaking, stallions from all over the square—young and old, earth ponies, pegasi, and unicorns alike—surged forward. It became a writhing, groaning mountain of muscle and fur. The crusaders were lost in the center, a whirlwind of legs, hooves, and other appendages. It was chaotic, messy, and overwhelming. Their small bodies were passed from stallion to stallion, their mouths and hooves and tails working without conscious thought. They were no longer individuals, but a single entity with one purpose: to please.

Apple Bloom found herself simultaneously using her tongue to service a burly carpenter while her hind legs were gripped by a pegasus. Sweetie Belle was trapped between two unicorn brothers, their horns glowing with magical energy as they took turns with her. Scootaloo's wings were spread wide, being used by three different stallions at once, her small body bouncing between them. The sounds were a cacophony of grunts, moans, and the squelching of their "work."

The climax was cataclysmic. A collective, deafening roar shook the very foundations of the statue as every stallion reached their peak simultaneously. A deluge, a veritable tidal wave of hot, sticky release, crashed over the three fillies. It was in their manes, their eyes, their mouths, their ears. They were submerged, drowning in the essence of Ponyville's stallion population. It filled the platform, splashed onto the cobblestones, and coated the statue's hooves. For a long moment, there was only the sound of heavy breathing and the drip, drip, drip of gallons upon gallons of fluid.

Slowly, shakily, three small forms pulled themselves from the sticky morass. They were unrecognizable. Dripping, soaked through, utterly coated from head to hoof in pearlescent white. Apple Bloom's red bow was a sodden blob. Sweetie Belle's purple mane was plastered to her face. Scootaloo's orange feathers were matted and heavy. They stood, trembling, on the precipice of either ultimate failure or glorious success.

They looked down at their flanks. And there, they were. Through the thick, glaze-like coating, new shapes shimmered into existence. On Apple Bloom's flank, three interlocking horseshoes. On Sweetie Belle's, a pair of entwined hearts. On Scootaloo's, a trio of wings, each one dripping.

A gasp, then a cheer. They saw each other's marks. They saw their own. Tears of joy mingled with the layers of cum on their faces. They had done it. They had found their destiny.

They stood on their shaky legs, raised their goo-covered hooves to the sky, and screamed with all the air in their lungs, their voices cracking with emotion and exhaustion.

"Yay! Cutie Mark Crusaders Cum Dumpsters!"
