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.

In the shadowed depths of an ancient forest on the fringes of Gaia, where the mist clung to towering trees like a lover's breath, Red XIII and Freya Crescent found themselves alone. The warrior from Burmecia, with her sleek furred body, elegant rat-like features, and powerful dracoon legs, had crossed worlds in a rare rift—perhaps a remnant of the Lifestream's chaos or some forgotten summon's whim. Red XIII, the noble guardian of Cosmo Canyon, his fiery red mane flowing like flames and his single golden eye gleaming with ancient wisdom, had sensed her arrival. Drawn by an inexplicable pull, a primal instinct buried deep in his beastly soul.

Freya stood tall, her silver-white fur shimmering under dappled moonlight, her red mage garb clinging to her curvaceous form—full breasts straining against the fabric, hips wide and inviting, her long tail swaying with graceful poise. Red XIII approached slowly, his muscular feline-leonine body rippling with power, his tail tipped with fire flickering softly. The air was thick with the scent of damp earth, wildflowers, and something more intoxicating: the musky heat of arousal beginning to bloom between them.
"You... you are not of this world," Red XIII rumbled, his voice deep and resonant, like thunder rolling through the canyon. He circled her, inhaling deeply, his nostrils flaring at her scent—sweet and fertile, laced with the rain-soaked aroma of Burmecia.

Freya's emerald eyes widened, but she did not retreat. Instead, a flush crept beneath her fur as she took in his majestic form: the broad shoulders, the powerful haunches, the thick sheath hiding what she could sense was a formidable cock. "Nor are you like any beast I've known," she whispered, her voice husky, laced with curiosity and desire. "But I feel... drawn to you. As if the fates have woven this moment."
Their muzzles drew closer, breaths mingling—hot, ragged. Red XIII nuzzled against her neck, his rough tongue grazing her soft fur, tasting the salt of her skin. Freya shivered, a soft moan escaping her lips as his warmth enveloped her. "I have long suppressed these urges," he admitted, his paw gently pressing against her thigh, claws retracted but firm. "But with you... I cannot."

Freya's hand—delicate yet strong—reached down, stroking along his mane, then lower, brushing the fur of his belly until she felt the heat radiating from his sheath. "Then don't," she breathed, her tail curling around his leg possessively. "Take me, Red. Claim me as your mate."

With a growl that vibrated through her core, Red XIII pushed her gently against a moss-covered tree trunk. The bark was cool and rough against Freya's back, contrasting the searing heat of his body as he pressed against her. His tongue lolled out, lapping at her neck, then down to her chest, tearing at her garb with careful teeth until her breasts spilled free—heavy, nipples hardening in the night air, pink and pert amid her white fur.

He suckled one greedily, his rough tongue rasping over the sensitive bud, drawing gasps from Freya. The taste of her skin was divine—musky, sweet, with a hint of sweat from her travels. She arched, fingers digging into his mane, the scent of her growing arousal filling the air like blooming jasmine mixed with raw need. "Oh gods... your mouth... so hot, so rough," she whimpered, her thighs parting instinctively.
Red XIII's paw slid between her legs, finding her already soaked folds. Her pussy was slick, swollen, the fur around it matted with her juices. He rubbed circles over her clit with a padded toe, feeling it throb under his touch. Freya bucked, crying out—a sharp, needy sound that echoed through the trees. The wet sounds of his paw working her filled the night, squelching softly as her arousal coated his fur.
"You're so wet for me," he growled, voice thick with lust. "Your body begs for my seed."

"Yes... please," Freya panted, her voice breaking as he slipped two thick digits inside her, stretching her tight heat. She clenched around him, walls pulsing, the sensation of his rough pads against her inner ridges sending sparks through her veins. The forest spun as pleasure built, her senses overwhelmed: the earthy smell of moss, the distant hoot of owls, the taste of his fur on her lips as she kissed his muzzle desperately.

Red XIII withdrew his paw, licking her essence from it with a satisfied rumble. "You taste like heaven." Then, he turned her around, pressing her chest against the tree. Freya braced herself, ass presented high, tail lifted to expose her dripping cunt—pink lips glistening, hole clenching in anticipation.

His cock had emerged fully now: thick, barbed like a feline's, ridged and veined, a deep red hue matching his mane, knotted at the base and already leaking precum that dripped hot onto her thigh. The scent of his musk was overpowering—primal, dominant, making her knees weak.

He mounted her swiftly, the weight of his powerful body pinning her deliciously. The tip of his cock nudged her entrance, hot and slick, teasing her folds before thrusting in with one powerful stroke. Freya screamed in ecstasy, her pussy stretching around his girth, the barbs scraping deliciously against her walls, sending jolts of pleasure-pain through her.

"So big... filling me completely," she moaned, pushing back against him. The sound of their bodies meeting was obscene—wet slaps echoing as he began to pound into her, hips slamming with beastly force. His balls, heavy and furred, swung to smack her clit with each thrust, the impact sending shockwaves up her spine.
Red XIII's growls mingled with her cries, his tongue lolling to lick her ear, tasting her sweat. "Tight... so perfect for me," he grunted, pace relentless. The air was thick with the scent of sex—her sweet nectar, his musky precum, the mingled heat of their fur.

Freya's first orgasm hit like a storm, crashing over her without warning. Her body seized, walls clamping down on his barbed cock like a vice, milking him as waves of blinding pleasure tore through her. "I'm cumming... oh fuck, Red! Don't stop!" she wailed, vision whiting out, every nerve alight. Juices squirted around his shaft, soaking his balls and dripping down her thighs in hot rivulets. The taste of blood from biting her lip, the overwhelming fullness, the rhythmic pounding—it was mind-blowing, shattering her composure.

But he didn't stop. If anything, he fucked her harder, the knot at his base swelling, pressing against her entrance. "More... give me more orgasms, my mate," he demanded, one paw reaching around to rub her clit furiously.

The second came faster, building from the ruins of the first. Freya's legs trembled, her tail thrashing as another climax ripped through her—deeper, more intense, her pussy convulsing wildly, barbs dragging against her g-spot with every withdrawal. "Yes! Breeding me... filling me!" she babbled incoherently, lost in euphoria, the world reduced to the slap of fur on fur, the burn of stretch, the intoxicating scent of his dominance.

Red XIII roared as his own release neared, knot popping inside her with a lewd stretch, locking them together. His cock throbbed, pumping rope after thick rope of hot, potent cum deep into her womb—fertile seed flooding her, painting her insides white. The sensation triggered her third orgasm, the most shattering yet: mind-blowing, soul-rending, her body arching in spasms as she howled his name, pussy squirting again in helpless surrender. She felt every pulse of his cum, the warmth spreading, claiming her utterly.

They collapsed together, tied by his knot, panting in the afterglow. Red XIII nuzzled her neck tenderly. "You are mine now," he murmured. "And I have bred you well."

Freya, spent and blissful, whispered, "I feel it... your seed taking root."

Months later, in a sun-dappled glen where Cosmo Canyon met Burmecian rains, Freya cradled their hybrid offspring—a beautiful cub with fiery red fur tipped in silver, a sleek rat-like muzzle blended with leonine strength, a tail that flickered with ethereal flame yet swayed with elegant poise. Small but fierce, with one golden eye and one emerald, the child scampered playfully, chasing fireflies with powerful little leaps that hinted at dracoon grace and guardian might.

Red XIII watched proudly, his paw resting on Freya's shoulder as she smiled down at their miracle. "Our little flame-tailed warrior," she cooed, the cub nuzzling against her with adorable growls.
In this new world they had forged, love and legacy burned eternal.
