The barn was dim except for the harsh glow of Peridot’s tablet screen. She sat perched on a stool, legs crossed, stylus poised like a scalpel. Across from her in the hammock, Lapis slouched with her arms folded, wet hair dripping slowly down her shoulders, eyes fixed on the floor. She looked like she’d rather sink into the earth than be sitting there.

Which was perfect.

Peridot adjusted her glasses and cleared her throat. “Phase Two,” she announced, voice crisp. “Initial conquest complete. Subject has displayed evidence of arousal, verbal admission, and physical compliance. Tonight’s objective: conditioning.”

Lapis groaned into her hands. “Why do you have to say it like that?”

“Because this is an experiment!” Peridot snapped, hopping off the stool and striding to the hammock. She jabbed her stylus against Lapis’s knee until she uncrossed her legs. “And you are my test subject. You agreed when you begged last night.”

“I didn’t—” Lapis started, but Peridot silenced her with a glare.

“You begged,” she repeated firmly, crawling up onto the hammock until she was straddling Lapis’s thighs. Her tiny fingers pinched Lapis’s chin, forcing her to look up. “You begged, and you said the word. Slut. Do you remember?”

Lapis’s cheeks darkened. She pressed her lips tight together, but her wings twitched restlessly.

Peridot’s grin sharpened. “Good. We’ll start there.” She tossed her tablet aside, grabbed Lapis’s ankle, and yanked her bare foot into her lap. The arch was pale, smooth, vulnerable. Peridot stroked a finger slowly across it, watching Lapis jolt. “Say it.”

Lapis’s voice was a whisper. “…I’m your slut.”

Peridot bent down, kissed the curve of her foot, then licked a slow stripe up the sole. “Louder.”

“I’m your slut,” Lapis gasped, toes curling hard.

Peridot sucked her big toe into her mouth with an obscene wet pop, swirling her tongue around it until Lapis cried out, fists clenching in the hammock ropes. She pulled off, saliva glistening across her lips. “Not good enough. Tell me more. Tell me what kind of slut you are.”

Lapis shook her head, shuddering. “I—I can’t—”

Peridot bit gently at her heel, making her yelp. “You can. Or I stop. And I know how badly you need me now.”

Her victim whimpered, breath breaking apart, then finally choked out, “I’m your dirty slut.”

Peridot’s eyes gleamed. She slid higher on her body, straddling her chest now, hands braced on her shoulders. “Again. Look me in the eyes this time.”

Lapis forced her gaze up, trembling, lips quivering. “I’m your dirty slut.”

Peridot ground down against her, sharp little moans escaping her throat. “Yes… yes, that’s right. Say you’ll let me use you however I want.”

“I’ll let you—ah—use me however you want!” Lapis cried, wings splaying wide.

Peridot bent close, her voice a hiss against her ear. “Say you love it when I humiliate you. When I make you crawl.”

Lapis’s whole face crumpled in shame and desire. She sobbed out the words: “I love it when you humiliate me! When you make me crawl!”

Peridot kissed her hard, biting her lower lip, grinding against her chest with frantic, needy jerks of her hips. “Stars, you’re perfect,” she gasped between kisses. “My perfect little puddle slut.”

Lapis broke then, moaning openly, arms wrapping tight around Peridot’s back like she couldn’t bear to let her go, even as the words of her humiliation rang in her own ears.

And Peridot? She was euphoric—scribbling the results into her mind, testing her limits and finding them deliciously elastic.

Tonight was just the first trial. Tomorrow, she promised herself, she’d push even further.

The next night, Peridot came prepared.

She dragged a crate into the middle of the barn and set her tablet atop it like a podium. On the floor beside it, she’d piled rope scavenged from the barn, a length of chain, and a ridiculous assortment of clamps and straps she’d welded together over the day.

Lapis walked in, dripping from the lake, and stopped short when she saw it all. “What… the hell is that?”

Peridot adjusted her glasses, stylus tapping. “Training equipment.”

Lapis frowned, folding her arms. “Peridot—”

“Shhh.” The smaller Gem hopped down from her stool, seized Lapis’s wrist, and tugged. “Come on, specimen. Time for your next trial.”

Lapis resisted at first, wings twitching wide. But Peridot stared her down, smirking, tugging harder, until Lapis finally let herself be pulled forward, muttering, “You’re insane.”

“Correct. Sit,” Peridot ordered, pointing at the floor.

Lapis sank to her knees slowly, eyes flicking nervously between the ropes and Peridot’s gleaming grin.

Peridot crouched in front of her, tilting her chin up. “Good girl. Now take off your top.”

Lapis’s cheeks flushed dark. “You’re serious?”

“Yes.” Peridot’s eyes glittered. “This is science. Strip.”

Her hands shook, but she obeyed, peeling the loose shirt over her head. Moonlight spilled through the rafters, casting silver across her bare shoulders, her breasts rising and falling unevenly.

Peridot’s grin widened. “Beautiful specimen.” She picked up the rope and began looping it clumsily around Lapis’s wrists, binding them behind her back. The knots were messy, but tight enough to hold. She stepped back, stylus in hand, admiring her work. “Restraint protocol: successful.”

Lapis shifted, testing the bindings, cheeks burning. “Peridot…”

“Shhh.” Peridot shoved her gently until she was kneeling upright. Then she stepped in close, climbing up onto the crate so she could tower over her. “Look at you. Ocean powerhouse, reduced to kneeling on a barn floor for me.”

Lapis bit her lip hard, chest heaving.

Peridot bent down, tugging her hair to tip her face upward. “Say it. Say you like being bound for me.”

“I…” Lapis hesitated, but the tug on her hair made her gasp. “I like being bound for you.”

Peridot purred, sliding her thumb over her lips. “Good girl. Now open your mouth.”

Lapis obeyed. Peridot slipped her thumb between her lips, pressing against her tongue, watching her cheeks hollow as she sucked automatically.

“Yes,” Peridot moaned softly, rocking her hips against the edge of the crate. “That’s it. My perfect little puddle slut on her knees, sucking like she was made for me.”

Lapis whimpered around her thumb, eyes dark with humiliation and need.

Peridot pulled free with a wet pop, smearing spit across her cheek. “You’ll crawl for me next. Crawl across the barn floor, tied up, and tell me what you are with every step.”

Lapis swallowed, trembling. “…I’m your slut.”

Peridot’s grin went feral. She hopped down from the crate, shoved Lapis gently to her hands and knees, and smacked her ass hard enough to make her yelp. “Louder.”

“I’m your slut!” Lapis cried, voice echoing in the barn as she crawled forward, rope digging into her wrists, bare feet dragging over the floorboards.

Peridot followed, crouching low, eyes drinking in every shameful movement, every moan. “That’s right. Keep saying it. Crawl for me. Show me you belong on the floor, begging for my touch.”

Lapis obeyed, crawling across the dusty boards, voice breaking with every admission: “I’m your slut! I’m your dirty slut! I’m nothing without you!”

Peridot’s whole body trembled with manic delight, scribbling the words into memory, her breath hot and ragged. This was better than any machine, any invention. This was perfection.

She pounced on Lapis then, knocking her flat to the floor, straddling her back, yanking her head up by the hair to hiss against her ear: “You’re mine forever. My first subject. My favorite toy. Say it.”

Lapis sobbed, voice raw, but clear: “I’m yours forever. Your toy. Your slut.”

Peridot laughed, wild and victorious, grinding down against her bound body as the barn echoed with the sound of submission.

The barn smelled of dust, sweat, and the faint copper tang of metal. Lapis knelt on the floor, wrists lashed behind her with barn rope, hair hanging in her face, her wings twitching as though they wanted to lift her out of the situation. She didn’t move. She didn’t dare. Not with Peridot pacing in front of her, tablet in one hand, something strange cradled in the other.

The object was long, cylindrical, studded with little green lights and wrapped in smooth synthetic casing. Tubes ran down its length, humming softly, ending in a rounded tip that glowed faintly.

Peridot held it aloft like a prize. Her grin was sharp and unhinged. “Behold. My newest creation: the Phalliform Penetrator. Version one-point-zero.”

Lapis blinked up at her. “You… you’re insane.”

“Yes,” Peridot replied smugly, tapping her stylus against the shaft, making it vibrate faintly. “But I’m also brilliant. This prototype has three settings, each calibrated for maximum… responsiveness. Tonight, you will be my data set.”

She crouched, bringing the humming device level with Lapis’s flushed face. “Open your mouth, subject.”

Lapis tried to glare, but her lips trembled. She hesitated—until Peridot tilted the synthetic head against her cheek. The faint buzz made her shudder.

“Open,” Peridot hissed.

Slowly, Lapis parted her lips. Peridot slid the tip inside, shallow at first, watching her cheeks hollow as she adjusted to the width. “Test One: oral accommodation.” She tapped the tablet, eyes glinting. “Response: gag reflex activated within two-point-three seconds. Promising.”

She pumped it a little deeper, grinning at the muffled moan that escaped. Drool spilled down Lapis’s chin, catching the green glow.

Pulling it free with a wet pop, Peridot wiped the shaft against Lapis’s flushed cheek. “Messy puddle. You’ll clean it later. For now—Test Two.”

She shoved Lapis backward onto the floor, straddling her hips. With one hand she pried her thighs apart, baring her glistening need. With the other she positioned the humming shaft at her entrance.

Lapis’s eyes went wide. “Peri—”

The synthetic tip pushed inside, slow but unrelenting. Lapis’s breath broke into a scream, head snapping back, wings slapping against the floorboards.

Peridot moaned right along with her, adjusting the dials until the shaft pulsed and thrummed inside. “Response: extreme sensitivity. Volume of subject’s cry exceeds expected range. Adjusting—yes, perfect.”

She thrust it deeper, watching her victim writhe, squirm, whimper. “Say it,” Peridot demanded, her voice hoarse. “Say what you are while I test you.”

“I’m—ahhh—I’m your slut!” Lapis wailed, back arching as the device vibrated harder.

Peridot grinned wildly, pumping it faster, recording with her tablet in her free hand. “Excellent. Test Three: endurance.”

She twisted a dial, and the phallus jolted to life with an obscene buzzing, filling Lapis so completely she nearly screamed herself hoarse. Peridot leaned over her, pressing her palm to her chest, pinning her down as she thrust with ruthless precision.

“Confess,” she hissed. “Say you’re nothing without me. Say you’re just a toy for my experiments.”

“I’m—yours—your toy!” Lapis sobbed, tears streaking down her flushed face. “I’m nothing without you! Please—please—!”

Peridot’s grin turned feral. “Yes. Perfect data. Subject fully conditioned.”

She rammed the device harder, until Lapis broke completely, screaming, thrashing, cumming hard around the synthetic shaft. Her body shook, slick gushing down her thighs, soaking Peridot’s hand.

Peridot slowed, then finally pulled the invention free, slick strings connecting it to her trembling subject. She licked her lips, wiping the mess across Lapis’s stomach like a signature.

“Trial complete,” she declared, standing over her like a conqueror. “Result: overwhelming success.”

Lapis collapsed, gasping, her body a wreck, eyes glazed. But even in her broken state, she whispered hoarsely: “Yours… I’m yours…”

Peridot beamed, hugging the device close to her chest like a trophy. “And that’s only version one. Imagine what version two will do.”
