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 pool pump hissed like a dying snake as the first thick rush of warm, pressurized water surged into Krystal. She stood on the edge of the luxurious indoor pool, blue bodysuit clinging to her already-curvy body, gold shoulder armor gleaming. The hose from the pump pressed firmly against her navel, the valve locked tight. “Nngh… oh gods… it’s starting,” she panted, green eyes fluttering. Her breasts felt heavier already, swelling outward in heavy, glossy orbs that stretched the blue fabric until the seams creaked.

“More… pump me harder…” Krystal moaned, voice husky and wet. She arched her back, hands bracing on the pool deck as the hose gurgled louder. Her belly ballooned outward in a slow, massive swell—round, translucent, water-logged curves pushing the loincloth up until it vanished between the swelling cheeks of her ass. The sound was constant now: *hiss-hiss-hiss*, water rushing in, making her skin stretch tight and shiny. Her thighs thickened, calves ballooning into powerful, wobbly pillars. Her huge breasts surged upward, the blue suit ripping open at the seams with loud *rrrrrip* sounds, heavy globes flopping free, nipples stiff and dark.

“F-fuck… they’re so big… so full…” she gasped, tongue lolling out as her belly pushed past her navel, turning into a gigantic, glistening beach ball of blue water. The pump strained, air hissing through the hose in rapid bursts. Her ass swelled next—massive, heart-shaped, two perfect translucent orbs that wobbled with every pump. The white countershading on her belly became a tight, drum-tight sphere. Her pink tail vanished inside the inflation, replaced by a thick, swollen blue base. Her feet slipped out of the sandals, toes spreading into powerful, padded paws that dug into the wood.

By the time the pump clicked off with a final *hiss*, Krystal was a living inflatable pool toy. Her entire body was a massive, translucent blue sphere—breasts the size of beach balls, belly a perfect globe, ass two huge jiggling orbs, limbs thick and wobbly. Water sloshed inside her, making everything glisten and slosh. The blue suit was long gone, torn away, leaving only her gold jewelry and the faint outline of her original form.

She swayed on the edge of the pool, huge breasts swinging heavily, belly sloshing with every breath. “Hngh… it feels so good… I’m so full… so tight…” Her green eyes rolled back, tongue hanging out in a lewd, ahegao grin. She reached down with a trembling paw and pressed her massive belly, feeling the water slosh inside her like a warm, heavy wave. “More… I need more… pump me again…”

The pump started up once more, hissing violently. The second wave hit harder. Her belly surged outward again—ballooning bigger, rounder, the water sloshing with wet, rhythmic *glorp-glorp*. Her breasts grew heavier, nipples leaking tiny beads of her own arousal as the skin stretched thinner. The sound of the pump mixed with her growing moans: *hiss-hiss-hiss*, *squeak-squeak-squeak* as her ass cheeks wobbled and slapped together.

Krystal’s mind was spinning. Pleasure built in waves. “I’m… I’m inflating… so much… look at my huge belly… it’s so full of me…” She slipped her paw between her thick thighs and rubbed her swollen, exposed vulva, fingers slipping through the shiny, glistening folds. Water and her own arousal mixed, dripping down her legs in shiny trails. Her tongue lolled further out, eyes crossed, a constant *hnnngh… hnnngh…* escaping her throat.

The pump never stopped. The third wave was relentless. Her belly exploded outward again—pushing past her navel, becoming a gigantic, water-logged sphere that made her whole body feel like it was being stretched and filled. Her breasts ballooned next, massive, heavy orbs that slapped wetly against her own swollen belly. The sound was constant now: *squeak-squeak-squeak-squeak*, the water sloshing inside her like a living drum. Her ass cheeks wobbled violently, the heart-shaped curves jiggling with every pump.

“I’m cumming… I’m going to cum from being inflated…” Krystal whimpered, voice breaking. She pressed both paws against her massive belly, feeling the water slosh violently inside her. The pressure was too much—too intense, too overwhelming. Her pussy clenched hard, lips swollen and puffy, clitoris throbbing against the tight, stretched skin.

The fourth wave hit like a tidal wave. Her belly surged outward one final, earth-shattering expansion. The pump screamed. Her belly ballooned bigger than ever—round, translucent, water-filled, the skin so tight it gleamed like glass. Her breasts surged upward in tandem, the two massive orbs pressing against her swollen belly. The sloshing became a constant, wet *glorp-glorp-glorp*. Her ass cheeks wobbled harder, slapping together with wet, obscene sounds.

Krystal’s eyes rolled back completely. Her tongue hung out long and thick, drooling. “I’m… I’m cumming—fuck—fuck—!” Her body locked up. The pleasure was too much, too intense, too overwhelming. Her pussy spasmed violently, gushing clear fluid mixed with water and her own arousal in powerful, uncontrollable jets that splattered across the wooden deck. Her belly contracted around the water inside her, the pressure making her orgasm even stronger.

She came harder than she ever had in her life.

Her whole body convulsed. The massive, translucent belly contracted in rhythmic waves—*glorp-glorp-glorp*—milking the water inside her as her pussy and ass clenched in unison. Clear fluid squirted from her swollen vulva in thick, hot pulses, splashing across the floor. Her massive breasts bounced wildly, nipples leaking tiny beads of milk that mixed with the water dripping from her stretched skin. Her eyes rolled back, tongue out, a constant high-pitched *squeak-squeak-squeak* escaping her throat as the orgasm tore through her.

“I’m cumming—cumming so hard—because I’m inflated—because I’m a pool toy—!” she screamed, voice cracking into a broken moan. Her belly pulsed one last time, forcing out a final gush of clear fluid mixed with water. Her whole body shook violently, paws digging into the deck, toes curling in ecstasy.

When the pump finally clicked off with a satisfied *hiss*, Krystal slumped forward, her massive, water-filled body resting on the edge of the pool. Her belly was a perfect, glistening globe—round, heavy, sloshing with every breath. Her breasts hung heavily, nipples dark and leaking. Her ass cheeks wobbled softly as she swayed.

She looked back at the viewer with glassy, blissed-out eyes, tongue lolling out, a dopey, satisfied smile on her muzzle.

“Best… inflation… ever…” she panted, voice hoarse and wet. “I love being a living pool toy… filled… full… exploding with pleasure…”

The water inside her sloshed gently, the only sound the soft, wet *glorp* of her own body settling after the mind-blowing climax.

And the night—and the pumping—was far from over.
