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 dim glow of the spaceship’s bedroom filled the air with a thick, humid haze. The window behind the massive bed showed a glittering starfield, but none of that mattered. Inside, the only light came from the soft bedside lamp and the glossy sheen of sweat already beading across Krystal’s stretched blue fur. She lay sprawled on her back, every inch of her enormous body taking up most of the mattress, her thick blue thighs quivering with each breath. The pink bandeau top had surrendered hours ago; the thin thong was the only scrap of clothing left, wedged so deep between her overflowing ass cheeks it might as well not exist. Her belly—god, her belly—rose and fell like a great white mountain, warm and heavy, the soft underside of her breasts resting atop the vast swell. Sweat rolled in slow, thick rivulets down the deep creases of her love handles, dripping from her areolas onto the white sheets below.

Fox McCloud knelt over her, his golden-furred body sleek and powerful, the white tank top clinging to his toned chest. His green pants had ridden up, and the hard outline of his cock pressed against the fabric. His bushy tail—still that ridiculous fluffy golden banner—wagged so hard the air around it rippled with motion lines. Green text floated beside it like living smoke: **WAG WAG GURGLE**.

“Fuck, Krystal… you’re gonna finish me off,” he growled, voice low and rough with lust, breath already hot against her muzzle. “Look at that gut. It’s so fucking *full* of me. So heavy. So *hungry*.”

Krystal’s long blue hair fanned out across the pillow, strands sticking to her sweaty cheeks. Her green eyes were glassy, heart-shaped pupils blown wide with bliss. Her tongue lolled out, thick and pink, dripping saliva in long strings. Chocolate cake—rich, dark, dripping with melted frosting—coated her muzzle, her lips, and ran in glossy trails down her chin to drip onto the massive underside of her breasts. Each slow, filthy lick sent fresh waves of sweetness exploding across her tongue, thick and creamy, the cocoa bitter against the sugary flood. She moaned, the sound vibrating through her swollen throat and deep belly.

“Nhmmhh… mmmmmm~” she purred, the words muffled around another huge bite. Chocolate filled her cheeks, making her jaw work in greedy, wet smacks. “So… *good*, Fox… the cake… it’s melting inside me… ahh… filling up all the empty places… mmmph!”

Her massive belly rumbled loud enough to shake the frame of the bed—**GURGLE… GURGLE… GURGLE**—the sound raw and wet, like a thunderstorm trapped inside her guts. The green text in the air pulsed in time: **GURGLE… GURGLE… GURGLE…**

Fox’s tail never stopped wagging. He leaned closer, pressing the hard bulge of his cock right against the side of her enormous thigh, the heat of his body searing through the thin fabric. One gloved hand stroked her sweat-slick fur, the other tilted the last piece of cake to her lips.

“Open up, pretty fox,” he whispered, voice thick with teasing. “Take it all. Every last crumb. Your belly’s already begging for more. Feel how it sloshes when you swallow? That’s me. That’s *my* cum in there, waiting to make you even bigger.”

Krystal obeyed instantly, her long pink tongue shooting out, scooping up every drop of frosting. She licked Fox’s fingers clean, eyes never leaving his, a soft, broken moan escaping with each swallow. The chocolate slid down her throat in a hot, slippery rush, pooling in the vast cavern of her stomach. Her belly swelled another inch, the skin stretching tighter, the pink thong now digging painfully into her mound. Sweat beaded on her forehead, rolled from her pointed ears, dripped from the tip of her tongue. The air around her was thick with the sweet scent of chocolate, the musky tang of her own arousal, and the salty, masculine heat rolling off Fox’s body.

She could feel everything—every nerve ending stretched and hypersensitive. The pressure of her own weight pinning her to the bed, the way her massive breasts shifted and spilled over her belly with every tiny movement, the slick slide of her own vaginal juices soaking through the ruined thong. Her claws flexed against the sheets, toes curling so hard the pads creased. Her belly hung lower now, the sheer weight making her hips tilt, her thick thighs spreading wider.

Fox’s cock was rock-hard now, throbbing. He reached down and freed himself, the thick orange shaft springing free, flushed and leaking pre-cum. Without a word he slid the head between her enormous, sweaty thighs, letting the hot, velvety length drag along the underside of her gut, coating himself in her sweat.

“Gonna fuck this fat belly while you eat, Krystal,” he hissed, voice cracking with need. “Gonna slide in and out, feel my cock bounce off your guts. You’re so fucking *warm* inside… so *tight* even after everything.”

Krystal’s eyes rolled back. She couldn’t speak—only whimpered and moaned around the next massive bite. Chocolate and saliva dripped from her open, panting mouth in thick strings that splashed onto her heaving breasts. Her belly gurgled louder, a wet, animal sound that filled the room. **GURGLE… GURGLE… GURGLE… GURGLE!**

Fox started to thrust—slow, deep rolls of his hips that made his cock drag through the valley of her thighs, the fat head nudging right against the base of her belly. Each movement sent fresh jolts of pleasure through her core. The pressure, the heat, the sheer overwhelming *size* of her body, the endless sweetness flooding her belly, the way her own sweat mixed with his pre-cum on her fur—it all crashed together like a tidal wave.

Her belly began to tighten. Not just from the cake now. The pressure inside her was building, impossible, unstoppable. Every swallow, every filthy squelch of her guts, every slap of Fox’s cock against her swollen thighs sent sparks straight to her clit. The thong had long since soaked through; her folds were puffy and dripping, the sensitive underside of her swollen labia brushing the base of her belly with every breath.

“Fox… Fox… I—I can’t… it’s too much… ahhh~” she gasped, voice cracking into a high, needy whine. Her hands—claws extended—clutched at the sheets, knuckles white. Her tail thrashed, smacking the mattress. Her breasts jiggled heavily with every rapid breath, nipples stiff and dark against the soaked fabric remnants.

Fox’s tail wagged harder, the green text blurring: **WAG WAG GURGLE GURGLE GURGLE!**

He pounded into her now, faster, the wet slap of skin on skin echoing with every thrust. The sound of her belly—**GURGLE… GURGLE… GURGLE…**—mixed with the obscene squelch of her soaked pussy and the wet, filthy noises of chocolate still coating her muzzle. Sweat flew from her body with every impact. The room reeked of sex, chocolate, and raw musk.

Krystal’s eyes locked onto his. She couldn’t look away. The pleasure was building in her core, a white-hot coil twisting tighter and tighter. Her belly felt like it was on fire—full, heavy, *alive*. The sheer volume of cake inside her, the way it sloshed and pressed against her clit, the endless gurgles that vibrated through her bones, the way Fox’s cockhead bumped her stomach with every thrust—*everything* was pleasure.

“I’m… I’m cumming… Fox… I’m—hands free—ahhhhn~!”

The orgasm hit her like a supernova. No fingers. No touch. Just the brutal, overwhelming assault of her own body.

Her entire frame locked up. Her back arched so hard her massive belly lifted off the bed for a split second, then slammed back down with a wet *thud*. A high, keening scream tore from her throat as her pussy clenched and spasmed—hard, violent, endless—clit pulsing against the base of her gut with every heartbeat. Juices squirted out around the ruined thong, soaking Fox’s thighs and the sheets in a hot, messy arc. Her eyes rolled back completely, tongue lolling out, drool and chocolate pouring from her open mouth in thick ropes. Her whole body shook, tits bouncing wildly, belly rippling with aftershocks that made her gut *gurgle* louder and louder, **GURGLE… GURGLE… GURGLE… GURGLE GURGLE!!!**

Fox lost it. “Krystal—*fuck*—I’m cumming too—take it—take it all—” He buried himself to the hilt inside her thigh, hips slamming forward one last time. Thick, hot ropes of his cum erupted straight into the tight heat of her pussy, pulsing deep inside her while she kept cumming, hands-free, body wracked in endless, screaming bliss.

The room filled with the wet, frantic sounds of their release—slapping flesh, gurgles, moans, the squelch of cum mixing with her juices. Fox’s tail wagged so hard it blurred. Krystal’s belly continued to *gurgle* long after the last drop, a satisfied, bloated symphony as the two of them collapsed together, sweat-slick, cum-filled, and utterly spent.

Fox kissed her sweat-drenched muzzle, still buried inside her, whispering, “Best… fucking… meal… ever…”

Krystal could only moan, a broken, dreamy smile on her cum-smeared lips, her enormous belly still twitching with aftershocks, **GURGLE… GURGLE…** the final, perfect sound of a body completely, utterly, mind-shatteringly full.
