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 air inside the training wing of the Great Fox was thick, humid, and ripe with the sharp tang of latex, sweat, and raw arousal. Fluorescent lights buzzed overhead like angry hornets, casting harsh white glare across the polished metal floor. Krystal stood in the center of it all, her massive purple breasts heaving inside the glossy, clinging bodysuit, nipples stiff and straining against the tight fabric like they were trying to punch through. Her blue tail flicked nervously, the fluffy tip twitching against the floor with every frustrated breath. The silver chastity belt locked tight around her waist felt heavier than any energy cannon she’d ever faced—cold metal biting into her hips, the wide straps digging into her soft fur, and that heavy, inescapable padlock dangling right between her thighs, mocking her.

Her green eyes were wide, glassy, and rolling back with every tiny twitch of her hips. Sweat beaded along her hairline and trickled in slow, delicious rivulets down the deep valley of her cleavage. The scent of her own body—musky, sweet, and desperate—hung in the air like perfume. Her tongue darted out, licking her lips, tasting the salt of her own sweat. Her thighs trembled. Her thick, blue ass cheeks clenched and unclenched as she tried to press her legs together and failed.

She was dripping.

Not a little. Not a tease. She was soaked through the crotch of her suit, the wet fabric squelching softly with every tiny shift of her weight. Her clit throbbed like a second heartbeat, swollen and aching so fiercely she could barely think. Five minutes. Five minutes since the last orgasm had been ripped from her body, and now every nerve screamed for release.

A low, mocking chuckle echoed off the walls.

“Well, well, well,” the voice of her best friend and former captain, Fox McCloud, purred from the shadows. He leaned against the wall, arms crossed, blue ears perked with pure amusement. His tail flicked lazily. “I haven’t cum in five minutes either. Sounds like we’re even, Krystal.”

Krystal’s ears flattened. Her blush burned hotter. “Fox… you little—” Her voice cracked, half growl, half whimper. She took one shaky step toward him, breasts bouncing heavily. The motion made the chastity belt shift, and the metal clinked loudly. “I can’t—fuck— I can’t stop. I’ve been like this for hours. Every time I think I’m close, it just… vanishes. I’m so wet I could drown in it.”

Fox’s golden eyes sparkled with wicked delight. He pushed off the wall and sauntered closer, boots clicking. “That’s the point, captain. You always need it. Always begging for it. Remember that time on the old planet, when you came so hard you blacked out? You were still throbbing for another ten minutes after.”

Krystal’s breath hitched. The memory burned hotter than the shame. She remembered the way her body had locked up, every muscle seizing, her cunt pulsing uselessly around nothing while she screamed his name. And now? Now she was right back to square one.

From the doorway, a third voice joined in—smooth, feminine, and dripping with amusement.

“Poor thing,” slipstream purred, leaning against the opposite wall with her arms crossed under her own chest, accentuating the way her own suit hugged her hips. “Look at you. Hands on your hips like you’re trying to hide how much you want to grab your belt and yank it off. I can smell it from here, Krystal. That sweet, needy musk. You’re leaking all over the floor.”

Krystal’s tail lashed. Her knees nearly buckled. “Slipstream… you don’t have to rub it in. I know I’m a mess.” Her voice was smaller now, breathy. “But I can’t… I can’t stop. My body won’t let me. Every time I get close, that thing just locks it away. I’m so horny I can feel it in my teeth.”

Fox stepped right up to her, close enough that she could feel the heat rolling off his body. He reached out and gently—oh so gently—traced one blue finger along the edge of her bodysuit, right over the hard bulge of the chastity belt. Krystal moaned, a high, desperate sound that echoed off the metal walls.

“Easy, easy,” Fox murmured. “You’re already shaking. I can feel how wet your thighs are through that suit. Soak. Soaking. Look at that pretty little spot right here.” He tapped the front of the belt, right over her dripping cunt. The sound was obscene—wet, slick, pathetic.

Krystal’s hips jerked forward on instinct. “Please… Fox… I need it. I need to cum so bad I can taste it. My clit is so swollen I can’t even rub myself anymore. It’s been five minutes and it feels like five years. I’m gonna lose my mind.”

Slipstream pushed off the wall and circled around behind Krystal, her breath warm against the back of Krystal’s neck. “Five minutes? Try longer. You came so hard last time you passed out for a full hour. Remember? Your tail was wagging so fast it looked like a helicopter.”

Krystal’s ears drooped. Shame and heat flooded her face. “Yeah… I remember. I was still twitching when you found me. I couldn’t even speak. Just whimpering like a bitch in heat.” She laughed bitterly, the sound broken. “And now here I am again. Trapped. Needing it constantly. I’m a nympho, Fox. A total, uncontrollable nympho. But you won’t let me have it. Not really.”

Fox’s grin widened. He hooked two fingers under the front of the belt and tugged—gently, just enough to make the padlock clink and Krystal’s breath catch. “That’s right. You’re mine to control. Mine to tease. Mine to edge until you’re begging so pretty you can’t even form words.”

Krystal’s breath came in short, panting bursts. The room felt smaller, hotter, the air so thick with pheromones she could almost see it. Her breasts rose and fell rapidly, sweat sliding between them in shiny trails. Her nipples were so hard they ached. “Please… please let me at least rub myself. Just a little. Just once. I’ll be good. I swear.”

Fox shook his head, slow and deliberate. “No. You’ll be good when I say you’re good. And right now? Right now you’re going to stand there and feel how wet you are while I talk to you about how long five minutes is.”

He leaned in until his muzzle brushed her ear, voice dropping to a husky whisper. “Five minutes, Krystal. Five. Fucking. Minutes. Since you came. Since your poor, aching cunt got its big orgasm ripped away from it. Imagine it—imagine the way your walls were squeezing around nothing, trying to pull me in, trying to milk me dry. And now? Now it’s all locked up. All yours. All denied.”

Krystal’s knees buckled. A full-body shudder ran through her. Her tail curled around Fox’s leg on pure reflex. “Fox… oh gods… I can feel it. The denial. It’s making everything worse. My clit is so sensitive now. Every little shift of my hips sends sparks straight to my brain. I can’t even think straight anymore.”

Slipstream stepped up on Krystal’s other side, pressing her soft breasts against Krystal’s back. Her hands slid up to cup Krystal’s heavy tits from behind, thumbs circling the stiff nipples through the suit. “That’s it. Feel it. Your body is screaming for release but your mind knows it won’t come. So now you’re just left with this throbbing, desperate ache. Look at you—eyes rolled back, tongue out, drooling a little. So fucking cute.”

Krystal whimpered, loud and broken. “Please… Slipstream… both of you… I can’t take it anymore. My thighs are shaking so hard. I can feel my cunt clenching around air. It’s empty and it’s burning. I need to cum. I need it so bad I’d let you lock me in here forever if it meant I could just—JUST ONCE—”

Fox cut her off by pressing a gentle, open-mouthed kiss to the sensitive spot just behind her ear. “You’re not getting it. Not tonight. Not ever, if I don’t feel like giving it to you. You’re a nympho, Krystal. You need this. You need us to control it. And we’re going to make you feel it. Every single second of every single day until you’re dripping down your legs and begging on your knees.”

Krystal’s breath hitched into a moan. Her body betrayed her—hips rolling forward, grinding uselessly against the cold metal of the belt. The wet spot on her suit grew bigger, darker. She could smell herself stronger now, that intoxicating, fertile musk filling the room until it felt like she was drowning in her own need.

Fox pulled back just enough to look her in the eyes. “Say it. Say who you are.”

“I’m… I’m Krystal the nympho,” she gasped, voice hoarse. “I need it constantly. I can’t stop. Please… please edge me more. Please make the denial worse. I want to feel it. I want to hurt.”

Slipstream laughed softly, the sound vibrating through her chest against Krystal’s back. “Good girl. Now keep still. We’re not done.”

The three of them stood there in the buzzing lights of the training wing—Krystal trembling, dripping, denied, and utterly, blissfully lost in the exquisite torture of orgasm denial—while the voices of her friends wrapped around her like velvet chains, promising that five minutes was only the beginning.

And somewhere deep inside her aching, throbbing core, a tiny spark of impossible hope flickered… hoping against all hope that tonight, just tonight, they would finally let her break.
