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.

Bulma's lab at Capsule Corporation was a mess of half-assembled gadgets and scattered blueprints, the air thick with the scent of soldering iron and fresh coffee. It was late afternoon, the sun filtering through the massive windows in golden shafts, casting long shadows across the room. She'd been tinkering with a new gravity device when Beerus sauntered in unannounced, his lithe purple form slinking through the door like a predator on the prowl. Whis wasn't with him this time—unusual, but Bulma didn't think much of it at first. The God of Destruction had a habit of showing up whenever he pleased, usually demanding food or entertainment.

"Ah, Bulma," Beerus purred, his voice a low, rumbling growl that vibrated through the air like distant thunder. His golden eyes gleamed with mischief as he floated lazily toward her workbench, his tail swishing behind him. "I've been bored out of my mind. The universe is so... predictable. But you, human—you always have something interesting up your sleeve."

Bulma wiped sweat from her brow with the back of her hand, her blue hair tied back in a messy ponytail, her tight white lab coat hugging her curves. She glanced up, trying to hide her irritation. "Beerus? What do you want now? If it's pudding, we're out. Vegeta's been training non-stop and ate the last batch."
Beerus chuckled, a sound that sent chills down her spine despite the warmth in the room. He hovered closer, his presence overwhelming, the faint scent of ozone and something ancient—almost feline musk—wafting from his skin. "Pudding? Oh, no. I have a different craving today." His eyes raked over her body, lingering on the swell of her breasts straining against her top, then down to her hips. "You've been useful to me before. Fixed my ship, hosted my parties. Now, I think it's time you... entertain me properly. Or perhaps I'll just blow up this little planet to cure my boredom."

Bulma's heart skipped a beat. Coercion from a god—it wasn't the first time, but this felt different. More personal. More dangerous. "W-wait, what? You can't be serious!" she stammered, her cheeks flushing red as she backed up against the workbench, tools clattering to the floor. The metallic tang of fear mixed with the lab's chemical odors in her nose.

Beerus's grin widened, revealing sharp fangs. "Oh, I'm deadly serious. Get on your knees, woman. Show me what that clever mouth of yours can do besides yapping."

Her mind raced. He's a god. He could destroy everything I love in an instant. Goku's off training, Vegeta's in the gravity room... no one's coming to save me. Swallowing hard, Bulma sank to her knees on the cold tile floor, the chill seeping through her jeans. Beerus floated lower, his Egyptian-style garb parting effortlessly as he exposed himself. Bulma's eyes widened in horror and disbelief.

His cock was monstrous. Easily as thick as her forearm and longer than her entire arm, it throbbed with otherworldly power, veined and ridged like some ancient relic forged in the heart of a star. The skin was a deep purple, almost glowing with an inner heat, and it pulsed with each beat of his divine heart. Below it dangled his balls—titanic orbs, each one larger than a basketball, heavy and swaying like pendulums of doom. The musky scent hit her full force now, a potent mix of sweat, spice, and raw masculinity that made her head spin.

He's too BIG! Bulma thought, her pulse thundering in her ears. How the hell am I supposed to handle that? It's impossible!

"Impressed?" Beerus taunted, his voice dripping with arrogance. He reached down with one clawed hand, gripping the base of his shaft and angling it toward her face. The tip, swollen and leaking a bead of clear, viscous pre-cum, brushed against her lips, hot and insistent. "Open wide, Bulma. Or should I make this planet go boom?"

Trembling, Bulma parted her lips, her breath coming in short, panicked gasps. The taste exploded on her tongue as she tentatively licked the tip—salty, bitter, with an underlying tang that was almost electric, like licking a battery. She wrapped her hands around the shaft, but her fingers couldn't even meet; it was too girthsome, the heat radiating through her palms like holding a live wire. She leaned forward, stretching her jaw as wide as it could go, and took the head into her mouth.

Immediately, she gagged. The sheer size forced her lips to stretch painfully, her cheeks bulging out like a chipmunk's. Beerus groaned, a deep, guttural sound that echoed off the lab walls, his tail lashing excitedly. "That's it... deeper."

Bulma tried, pushing forward inch by agonizing inch. The cock invaded her mouth, filling every crevice, pressing against her tongue and the roof of her palate. Her saliva mixed with his pre-cum, creating a slick, messy slurry that dribbled down her chin in thick strands. The ridges scraped against her inner cheeks, sending sparks of discomfort through her nerves. She could feel the vein on the underside pulsing against her tongue, hot and alive.

He's too BIG! her mind screamed again as she forced more in. Her throat constricted in protest, but she swallowed hard, trying to relax. With a wet, choking glurk, the head breached her throat, and oh gods, the bulge—it was obscene. From the outside, anyone watching would see her neck distend grotesquely, the outline of Beerus's massive cock visible like a snake swallowing its prey in reverse. It pushed outward, stretching her skin taut, the purple hue faintly visible through her flesh.

"Guh—ack!" Bulma choked, her eyes watering as tears streamed down her face. The sound was wet and desperate, a series of gags and slurps filling the room, mingling with Beerus's pleased purrs. Her nose buried against the base, inhaling that overpowering musk, making her dizzy. She reached down with one hand, trying to steady herself by caressing his balls. But they were enormous—each one dwarfed her palm entirely. She could only cup a fraction of one, feeling the heavy, wrinkled skin, the warmth seeping into her fingers. They churned slightly under her touch, full and potent, like they could flood an ocean.
Beerus laughed, a cruel, echoing boom. "Pathetic human. Can't even handle a god's equipment? Keep going—suck harder, or I'll ram it in myself."

Fueled by fear, Bulma bobbed her head, her blue hair matted with sweat and sticking to her forehead. Each thrust forward sent the cock deeper, the bulge in her throat swelling and receding like a piston. Her gag reflex fired relentlessly—gluck, gluck, hack—spit flying from the corners of her mouth, soaking her top and making it cling transparently to her heaving breasts. The taste was overwhelming now, a constant flood of pre-cum coating her throat, making her swallow convulsively around the intrusion. Her lungs burned for air, each breath a ragged wheeze through her nose, filled with his scent.

He's too BIG! I can't breathe... it's tearing me apart! Panic surged as black spots danced in her vision. She massaged his balls desperately, her small hands kneading what little she could grasp, feeling them tighten and swell even larger under her touch. The texture was rough, velvety, and impossibly heavy, like holding warm boulders. Beerus moaned louder, his claws digging into her scalp, forcing her rhythm faster.
"Deeper, you worthless mortal! Worship it!" he snarled, his voice husky with pleasure. The room spun for Bulma—the metallic clatter of tools in the background fading, replaced by the wet symphony of her struggles: the squelch of her throat accommodating him, the drip of saliva pooling on the floor, the thunder of her heartbeat in her ears.

Her jaw ached, on fire from the strain; her throat felt raw, bruised from the inside out. The bulge pulsed visibly, each throb sending waves of nausea through her. She gagged harder now, bile rising but suppressed by the sheer mass blocking her esophagus. Air was a luxury she could barely snatch, her chest heaving, nipples hardening against her soaked fabric from the adrenaline and unwanted friction.
Too... BIG... can't... hold on... Her thoughts fragmented as oxygen deprivation set in. The world blurred, Beerus's form a hazy purple giant above her. She was choking, gagging uncontrollably now—violent heaves that made her body convulse, but still she pushed on, driven by terror. Her hands slipped on his slick shaft, fingers pruning from the mess. Just as her vision tunneled to black, her body going limp, Beerus's laughter rang out, echoing in her fading consciousness...
