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 forest air was thick with the sweet, heady musk of arousal, a scent that clung to the grass and made the leaves rustle with something far more primal than wind. Sunlight filtered through the tall blue-green trees in golden shafts, catching on sweat-slick fur and glistening skin. In the center of this lush clearing, two quadrupedal beauties knelt in perfect, teasing invitation, their bodies arched in pure estrus.

Fay Spaniel lay on her belly first, the fluffy white fur of her back and tail glowing like fresh snow. Her long, fluffy white tail—once so playfully curled—now stood stiff and high, the bushy tip trembling. Between her spread thighs, her canine pussy was swollen and dripping. The soft pink folds parted slightly with every shallow breath, revealing the swollen, throbbing clit and the slick inner walls that glistened with clear nectar. A thick, pearly strand of arousal already stretched from her glistening slit toward the ground, twitching with every tiny movement of her hips. Her large pink nipples stood hard on her perky breasts, leaking thin trails of sweet milk that ran down the sides of her chest. Her red bow sat lopsided on her head as she wagged her tail in eager little circles, blue eyes half-lidded and sparkling with mischief.

Miyu Lynx was right beside her, a far more dominant contrast. Her orange-and-brown spotted fur rippled with every breath, the black rosettes on her skin dark with excitement. Her spotted tail lashed lazily above her, the white tip flicking with predatory grace. Her feline pussy was even more swollen, the plump lips puffy and parted to expose the slick, pink slit and the swollen nub of her clit peeking out. Clear fluids coated the insides of her thighs, dripping in slow, heavy strands onto the grass. Her breasts hung heavy and full, teats dark and leaking sweet milk in constant rivulets. Her black-tipped ears twitched, and the gold ring in her left ear caught the light as she tilted her head, tail curling invitingly.

Both girls were in full heat—canine and feline instincts blazing, bodies aching to be filled, bred, claimed. Their muzzles hung open, tongues lolling, hot breaths puffing in visible clouds that smelled of arousal and need.

Fay’s voice came first, a sweet, girlish yip that vibrated with lust. “Woof~ ♡” She wagged harder, the motion making her fluffy tail sway and her dripping pussy clench visibly. “Miyu’s teasing you again, isn’t she? Heh… I can smell it. Your scent is getting thicker… hotter…” She crawled forward on all fours, her white breasts swaying, nipples dragging lightly across the grass. Her blue eyes locked onto yours as she rose up on her elbows, presenting her rear even more shamelessly. “Look how wet I am, little one. Feel how my pussy is pulsing for you? It’s all yours, Fay’s sweet canine cunt… dripping, aching, empty. You wanna mount me? You wanna knot this fluffy tail with your fat cock?”

Miyu’s laugh was low, husky, and dripping with teasing heat. She pushed herself up on her front paws, her spotted body flexing, tail curling higher to show everything. Her golden eyes glittered with playful dominance. “Meow~ ♡” she purred, the sound rolling out like velvet over gravel. She leaned back, spreading her legs wider so her swollen feline slit gaped open, the glistening pink folds shining wetly. A long, thick string of arousal swung from her clit before it broke and fell. “You think you can choose? Look at her… so eager and submissive. But I’m the one who hunts. I’m the one who knows how to use my tongue… how to make you throb just by licking your balls while you stare at Fay’s dripping cunt.” She smirked, fangs glinting. “Mmm, I bet you’re leaking already, aren’t you? That big, fat cock of yours straining in those pants. I can smell it. Salty, needy. I wanna taste it. I wanna wrap my hot lips around your shaft and suck until you’re groaning my name.”

Fay giggled, the sound high and breathy, and crawled closer until her fluffy white tail brushed your legs. Her hot breath ghosted across your skin, carrying the sweet canine musk. “Miyu’s so naughty today…” she whispered, voice husky. “She’s been edging herself for hours, cumming just thinking about a thick, knotted cock stretching her. But today I want it too… I want it so bad I’m leaking down my thighs. Please… look at my pussy. It’s twitching for you. See how my clit is swollen and begging?” She reached back with one paw, spreading her labia wider with trembling fingers, exposing the glistening, fluttering entrance. “Knot me. Tie me up. Breed this fluffy white dog until I’m stuffed and swollen and dripping your seed for days.”

Miyu’s tail lashed once, hard. She growled playfully, the sound mixing with her purr. “Oh? You wanna breed the little puppy first?” She leaned forward, her heavy breasts brushing Fay’s back, nipples dragging across white fur. “Tsk. That’s my job. I’m the wildcat. I’m the one who’ll ride you reverse, tail high, while Fay watches and licks her own clit. I’ll squeeze my tight feline pussy around you, milk you dry, then I’ll make you mount her and fill her while she howls your name.” She nipped playfully at Fay’s shoulder, making the smaller girl yelp in delight, then turned back to you, ears flat and ears perked. “But first… I need you to come closer. I need to smell your cock up close. I want to taste the precum already leaking for us. Mmm… it smells so good… so warm… so thick.”

Both girls moved in perfect sync, their bodies swaying, tails wagging and lashing, breasts swaying and leaking. The air was saturated with the combined scent—sweet canine honey, tangy feline musk, and the raw, animal need of two girls in heat. Sweat glistened on their fur. Saliva dripped from their open muzzles. Their pussies throbbed visibly, clenching and releasing in time with their racing heartbeats.

Fay’s blue eyes fluttered shut as she nuzzled your thigh, her hot tongue flicking out to lick a slow, teasing stripe up your inner leg. “Woof… you taste so good… salty and warm… I wanna bury my face between your thighs and suck you dry while Miyu eats my pussy. Please… I’m so wet. My juices are running down my legs. I need your cock. I need it deep.”

Miyu’s golden eyes narrowed with lust. She crawled onto Fay’s back, pressing her spotted body against the smaller girl’s white fur, her leaking nipples sliding along Fay’s spine. “Mmm, that’s it, puppy,” she cooed, voice thick with teasing command. “Beg for it. Show me how bad you want it. I’m going to take you first—slow, deep, stretching your tight feline cunt until you’re squirming and mewling. Then I’ll make you fuck Fay while she screams. But right now…” She reached back, grabbed your cock through your pants with one paw, and gave it a firm, possessive squeeze. “Right now I’m going to make you throb so hard you’ll explode just from my tongue. Ready, my loves? Let’s see how loud we can make you moan.”

The forest held its breath. The two girls in heat stared up at you, pussies dripping, breasts leaking, tails high, voices husky and dripping with promise. Fay wagged faster. Miyu’s tail curled higher. And the air grew thicker, sweeter, hotter with every second of pure, aching need.

Their bodies trembled. Their eyes burned. Their voices whispered the same desperate, filthy promise over and over.

“Take us… breed us… fill us both…”

“Meow~ ♡”

“Woof~ ♡”

And the forest waited, dripping, aching, and utterly ready for whatever came next.
