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 sun had long dipped below the jagged peaks of the Great Barrier mountains, leaving only the flickering glow of a massive bonfire to illuminate the secluded clearing. The air was thick with the scent of pine resin, smoked meat from a forgotten hunt, and something far more primal—musk, heavy and animal, radiating from the colossal form of Alistar the Minotaur.

Poppy stood before him, hammer resting against a boulder, her blue armor plates glinting in the firelight. The tiny yordle barely reached the height of his knee, yet her gaze was fixed upward, defiant and burning with a hunger that had been building for weeks. Ever since their paths had crossed in a brutal skirmish against Noxian raiders, something unspoken had crackled between them. His raw, unstoppable strength. Her unyielding determination. Tonight, in this hidden glen far from Demacia’s watchful eyes, that tension had finally snapped.

Alistar’s massive chest heaved, nostrils flaring as he looked down at the brave little warrior. His furred hide glistened with sweat, muscles rippling like forged steel beneath dark skin. Between his thick, tree-trunk thighs hung the source of the overwhelming musk: a sheath the size of Poppy’s torso, already swollen and dripping. Below it swayed two colossal balls, each easily larger than her head, heavy and churning with pent-up seed.

“You sure about this, little one?” Alistar’s voice rumbled like distant thunder, deep and gravelly, laced with both concern and barely restrained lust. “I’m… not built for gentleness.”

Poppy’s cheeks flushed beneath her helmet, but she didn’t look away. Her voice came out breathy, determined. “I’ve faced Void monsters, Ruination wraiths, and worse. I want you, Alistar. All of you. Don’t hold back.”

A low, guttural growl escaped him. With one massive hand—fingers thicker than her arms—he scooped her up as easily as a child lifting a doll. Poppy’s breath hitched as she was lifted high, legs dangling, until she was eye-level with his broad snout. He nuzzled her gently, hot breath washing over her face, smelling of earth and wild heat. Then his other hand gripped the base of his sheath and squeezed.

The flare of his equine cock erupted forth with a wet, obscene schlick. It surged out longer than Poppy’s entire body—three feet of thick, veined, mottled pink-and-black shaft, as wide as her waist at the medial ring, flaring even broader at the fat, flared head. Pre-cum already drooled in thick ropes from the gaping urethral slit, splattering onto the grass below like heavy rain. The scent hit her immediately: salty, musky, overwhelmingly virile, making her head spin and her tiny pussy clench with need.

“Oh founders…” Poppy whispered, eyes wide, one hand reaching out to touch the throbbing underside. Her palm barely covered a fraction of its girth. It pulsed under her fingers, hot as a forge, veins like steel cables beneath velvet-smooth skin.

Alistar’s balls churned audibly, sloshing with gallons of thick minotaur seed. He lifted her higher, positioning her tiny body above the monstrous cock. Poppy’s armor had already been stripped away earlier in their heated kissing; now she was naked, pale blue skin flushed, small breasts heaving, her slick folds glistening in the firelight.

He lowered her slowly, letting the flared head kiss her entrance. Even just the tip was wider than her hips. Poppy gasped, legs spreading instinctively as the pressure built. The heat was intense, the slick pre-cum coating her thighs in sticky strands.

“Relax, little hammer,” Alistar murmured, voice thick with restraint. “Let me in.”

With a slow, inexorable push, the flared crown breached her. Poppy’s scream echoed through the clearing—half pain, half ecstasy—as her tiny pussy stretched impossibly around the invading girth. Her lips parted obscenely wide, clinging to every ridge and vein. Inch by agonizing inch, he fed her onto his shaft, her belly already beginning to distend outward in a grotesque, lewd bulge that traced the shape of his cockhead pushing deeper.

The sensation was overwhelming: burning stretch, impossible fullness, every nerve in her body screaming in pleasure-pain. She could feel her inner walls forced apart, molding perfectly around the invading monster. Her juices squirted out around the seal, dripping down his shaft in rivulets.

Halfway down—barely a third of his length inside—her belly bulged hugely, the outline of his flared head visible beneath her taut skin like a fist pressing from within. Poppy’s eyes rolled back, mouth open in a silent scream as her first orgasm crashed through her without warning. Her tiny body convulsed, pussy clamping rhythmically around the massive intrusion, squirting clear fluid in forceful jets that soaked Alistar’s fur.

“F-fuck… so big… gonna break me…” she whimpered, voice trembling, but her hips rocked greedily for more.

Alistar’s growl deepened. With effortless strength, he shifted his grip. His massive arms looped under her knees, pulling her legs up and back until her ankles were locked behind her head. Full nelson—her tiny body folded in half, completely helpless, arms pinned against her sides by his forearms. She was locked in place, impaled and exposed, nothing but a living sleeve for his colossal cock.

The new angle drove him deeper. Another foot of shaft sank in with a wet squelch, the bulge in her abdomen surging upward until it distorted her ribcage. Poppy’s second climax hit immediately, harder than the first—her vision whited out, body seizing, a wordless wail tearing from her throat as her pussy spasmed wildly.

Alistar began to thrust.

Each movement was slow at first, deliberate—pulling back until only the flare remained inside, her stretched lips gaping obscenely, then slamming forward with earth-shaking force. The impacts made wet, lewd slaps that echoed like thunderclaps. Her belly bulged and receded in rhythmic waves, the outline of his cock visible in perfect detail: the flare, the thick medial ring, every pulsing vein.

Poppy’s world dissolved into sensation. The overwhelming stretch burned deliciously; the heat of his shaft radiated through her core; the constant pressure against her cervix sent lightning bolts of pleasure up her spine. She could hear everything: the wet squelching of her overstuffed pussy, Alistar’s heavy grunts and snorts, the sloshing of his colossal balls slapping against his own thighs, her own high-pitched moans and squeals rising in pitch with every thrust.

Smell and taste flooded her senses too—his musk was everywhere, thick and heady, coating her tongue as she gasped open-mouthed. Drool spilled from her lips, mixing with tears of overstimulation. Pre-cum bubbled out around his shaft with every withdrawal, splattering her face and chest in hot, sticky ropes.

“Take it… all of it…” Alistar snarled, losing control. His pace quickened, hips pistoning with brutal power. The ground trembled beneath his hooves. Poppy’s body jolted helplessly in the full nelson lock, breasts bouncing wildly, belly distorting grotesquely with each savage thrust.

Orgasm after orgasm ripped through her—third, fourth, fifth—until she lost count. Each one more intense than the last, her pussy gushing endlessly, squirting in arcs that rained down around them. Her voice broke into hoarse screams: “Yes! Yes! Fuck me! Ruin me with that monster cock!”

Alistar’s balls drew up tight, each one swelling even larger as climax approached. The churning grew louder, a deep, wet gurgling audible even over their rutting.

“Gonna… flood you…” he roared, voice shaking.

His cock throbbed violently inside her, stretching her even wider. The first jet of cum erupted like a firehose—scalding hot, impossibly thick, blasting directly into her womb with cannon force. Gallons surged forth in endless pulses, each one stronger than the last.

Poppy’s eyes snapped wide as her belly began to inflate. Rapidly. Her womb filled instantly, then overflowed, cum forcing its way deeper into her body. Her abdomen rounded out, then ballooned—skin stretching taut and shiny as gallons pumped into her. The bulge grew massive, far beyond the shape of his cock, turning her into a bloated, cum-stuffed balloon.

She came again—harder than ever—screaming as the pressure triggered a chain of mind-shattering climaxes. Her body convulsed helplessly, pussy milking his shaft for every drop.

But the torrent didn’t stop. More cum blasted in, her belly swelling to the size of a beach ball, then larger—skin creaking audibly, veins visible beneath the strain. Her limbs were forced outward by the sheer volume, tiny body dwarfed by the sloshing, gurgling orb of her midsection.

Alistar bellowed in release, hips bucking wildly. One final, monumental surge—and the pressure became too much.

With a deafening, wet POP of release, the seal broke. Cum exploded backward around his shaft in a geyser, but the forward force launched Poppy upward like a rocket. Still locked in full nelson, still impaled balls-deep, she rocketed off his cock in a torrent of white.

Her bloated body sailed through the air—dozens of yards—trailing ropes of thick minotaur seed like a comet’s tail. Cum continued to spray from her gaping, ruined pussy in forceful jets, her final orgasm still ripping through her as she flew.

She landed with a massive splash in a nearby mountain stream, the impact sending up a plume of water and cum. The cold shock only heightened her bliss; she floated there, belly slowly deflating as gallons of seed poured out of her in a steady river, body trembling with aftershocks.

Back at the fire, Alistar stood panting, cock still hard and dripping, balls already refilling. His eyes glowed with satisfaction—and promise.

“Next time,” he rumbled to the night air, “I won’t let you fly so far.”

Far downstream, Poppy floated on her back, a dazed, blissful smile on her lips, already craving more.
