The barn was quieter than it had been in days. No humans, no sweat and hay-stained chaos, just the hum of Peridot’s equipment and the faint scratching of her stylus against her tablet. She stood on her bench like a general surveying her troops, her grin sharp with manic excitement.

“New phase! Human acquisitions: stabilized. Subjects dispersed to home environments. Which means…” she adjusted her visor, eyes gleaming, “…it’s time to begin Gem fusion trials.”

Amethyst sprawled on a haybale, arms behind her head, chewing on a piece of straw. “Heh. Kinda figured this was coming. You’ve been eyeing me and Pearl like test tubes.”

Pearl flushed azure, smoothing her tunic nervously. “Well—I—fusion isn’t something to be taken lightly, Peridot. It’s not a game.”

Peridot hopped down, marching right up to Pearl with a smirk. “Game? Correct, it is not. It’s science! I’ve cataloged your individual reactions in explicit detail—” her eyes flicked over Pearl’s hips, then to Amethyst’s broad shoulders, “—and now I need data on your combined form. Hypothesis: new heights of stimulation and synergy.”

Amethyst snorted, stretching lazily. “She just wants to see how tall we get so she can climb us like a jungle gym.”

Pearl shot her a sharp look. “Amethyst!”

But Peridot only cackled, claws clicking excitedly as she waved her tablet. “Both of you — fuse. I demand Opal at once!”

Pearl hesitated, wringing her hands. “You can’t just demand it, Peridot. Fusion requires—”

Amethyst popped up beside her, nudging her hip with a smirk. “Relax, P. We’ve done this before. Let’s give the little gremlin her big show.”

Peridot’s grin widened. “Yes! Yes! Show me your synergy!”

With a reluctant sigh and a resigned nod, Pearl extended her hand. Amethyst took it with a flourish, and they began to dance. Peridot watched in awe as they came together in a burst of light and color, their forms twining and colliding.

Peridot shielded her eyes, cackling as her tablet recorded every flicker. “Yes! Light intensities at maximum! Data pouring in—!”

When the glow cleared, Opal stood tall in the barn, her long hair cascading down, bow slung across her back, her body a perfect meld of grace and raw strength. She blinked down at Peridot with serene curiosity.

“Hello again,” Opal said, her voice smooth, resonant.

Peridot’s grin turned feral, visor sliding down her nose as she scribbled furiously. “Magnificent. Twice the height, exponential beauty, musculature perfection! Opal, you are my next test subject!”

Opal tilted her head, her calm expression tinged with amusement. “You’re… very excited.”

Peridot pointed her tablet at her like a weapon. “Excited? I am electric! You are a fusion, a symphony of two of my favorite toys, and I intend to take you apart and put you back together until I’ve learned everything!”

Her cackle filled the barn, echoing under the rafters.

Opal arched a brow, folding her arms. “And if I refuse?”

Peridot’s grin only sharpened. “Oh, you won’t. Pearl’s craving to prove herself. Amethyst’s thirst for chaos. Both amplified in you.” She stepped closer, her little hands clenching into fists of manic certainty. “Admit it, Opal—you want this trial.”

Opal’s calm cracked with the faintest blush, her lips twitching into the barest smirk. “Maybe.”

Peridot hopped back onto her bench, raising her tablet like a conductor’s baton again. “Then let the fusion trials… commence!”

Opal let out a patient sigh. “And how should we commence?”

Peridot beamed. “I require you naked! Your beautiful, elegant body on all fours for me to examine!”

Opal’s clothes disappeared as her towering form knelt in the center of the barn, her pale hair cascading over her shoulders as she set her bow aside with quiet grace. At Peridot’s command, she lowered herself onto her hands and knees, her long body folding in a way that made the barn feel small around her.

Peridot circled her like a predator, tablet in one hand, stylus in the other. Her grin was sharp but controlled, her tone clipped and clinical. “Subject designation: Opal. Fusion of Pearl and Amethyst. Phase One: full-body examination.”

Opal’s lips quirked faintly, a mix of amusement and resignation. “Do I even have a choice?”

Peridot smirked, clicking her stylus. “Negative. And if you did, you’d still choose this. Both of your halves are aching to prove themselves to me.”

She crouched at Opal’s feet first, her small hands tracing over long toes. She leaned down and dragged her tongue slowly across the arch of one massive foot, humming as she scribbled. “Feet: larger than either half alone. Taste… faint mineral tang. Callusing minimal despite Amethyst’s rough habits — Pearl’s meticulousness dominates here.” She nipped at the sole, earning a quiet gasp. “Highly responsive to oral stimulation.”

Opal’s blush deepened, her breath uneven. “You don’t have to narrate everything.”

Peridot licked her lips, smirking up at her. “Correction: I absolutely do.”

She moved up to Opal’s long legs, fingers digging into her calves and thighs, squeezing, slapping. The sound of palm on skin echoed sharp in the barn. “Legs: sturdy, muscular. Striking balance of Amethyst’s stocky build and Pearl’s dancer’s form. Reaction to spanking—” she smacked the back of one thigh, smiling at the twitch it drew—“noted as positive.”

Opal let out a hiss between her teeth, her composed voice cracking faintly. “Mmm… data… collected.”

Peridot’s grin widened. “Don’t mock me.” She climbed onto the small of Opal’s back, standing proudly before sliding down again, positioning herself at the swell of her ass. She cupped both cheeks, kneading, spreading them with clinical care, then slapped hard. The loud crack made Opal jerk and groan.

“Gluteal region: exemplary. Volume exceeds Pearl’s by 140%. Spank-resistance threshold appears high.” She leaned in, dragging her tongue across the curve, scribbling as she tasted. “Flavor: mineral with faint sweetness. High oral appeal.”

Opal’s hair curtained her flushed face as she exhaled shakily. “Peridot…”

“Quiet, subject.” Peridot’s voice was firm, confident. She slid her hands lower, between Opal’s thighs, spreading and examining her pussy with slow precision. She licked, long and deliberate, her tablet screen glowing faint as she recorded notes. “Vaginal entrance: wetter than Pearl alone, tighter than Amethyst alone. Immediate reaction to oral—ahhh, very high.” She licked again, savoring the moan it earned. “Clitoral response: exquisitely sensitive.”

Opal trembled, her voice uneven now. “You’re… relentless.”

Peridot’s smirk softened into something smug. “Relentlessness is science.”

She slid beneath her, squeezing and weighing Opal’s breasts, scribbling as she toyed with her nipples, rolling them until they hardened. “Breasts: larger than either source Gem. Density firm yet yielding. Oral reaction—” she latched on, sucking hard, making Opal arch and moan—“immediate. Sensitive.”

Her stylus clicked furiously, her eyes gleaming behind fogged lenses.

Finally, Peridot climbed up, standing in front of Opal’s head, looking up at her serene, flushed face. She tapped her chin. “Mouth: subject displays Pearl’s reserve and Amethyst’s hunger. Oral cavity to be tested.” She leaned in and kissed her roughly, her tongue forcing past Opal’s lips, exploring her mouth with greedy precision. Pulling back, she scribbled with a smirk. “Tongue: long, pliant, flavor complex. Highly promising for reciprocal trials.”

Opal panted, her composure cracked, hair wild around her flushed cheeks. “You… enjoy this far too much.”

Peridot beamed, walking around the prone fusion with a victorious grin. “Enjoyment is irrelevant. What matters is data.” She clicked her stylus once more. “Phase One: complete. Subject Opal: thoroughly catalogued.”

She smacked Opal’s ass one more time, relishing the sharp groan it drew. “Phase Two begins immediately.”

Peridot circled Opal’s long frame, tapping her stylus against her tablet as the towering fusion steadied her breath. The blush on Opal’s cheeks hadn’t faded from the full-body exam, and Peridot’s grin only widened.

“Phase Two: endurance calibration.” She snapped her fingers, and the charging station in the corner hummed. One of her synthetic phallus prototypes lifted itself free with a faint whirr, floating obediently into her hands.

Opal eyed it, amused. “Always prepared.”

Peridot smirked, strapping it onto herself with an efficient tug of leather straps. “Of course. You don’t conduct groundbreaking experiments by improvising.” She gestured sharply. “Now. Roll onto your back.”

Opal hesitated a moment, then obeyed, reclining slowly in the hay. Her long limbs folded, knees bent, chest rising with slow composure. The contrast between her poised beauty and the submissive position only made Peridot’s smirk sharper.

“Excellent. Display optimal,” Peridot murmured, climbing up onto Opal’s thighs, adjusting her visor as if preparing to perform surgery. “Size differential noted. This angle ideal for control.”

She lined herself up and pressed forward, her little green frame dwarfed against Opal’s tall, elegant body. The moment the phallus slid inside, Opal gasped, her composure breaking with a soft groan.

Peridot scribbled with one hand while she thrust with the other. “Reaction immediate. Internal pressure… substantial. Subject highly accommodating despite initial tightness. Endurance threshold test initiated.”

Opal let her head fall back, her hair spilling across the hay, her voice breaking into uneven moans. “Nnnhhh—Peridot—”

Peridot leaned forward, adjusting her visor with a smirk. “Yes. Say my name. Your halves begged for me separately—now fused, you crave me exponentially.” Her pace quickened, her grin manic but measured. “Endurance trial begins at moderate thrust frequency.”

The barn door creaked.

Garnet stepped in, her shades catching the dim light, her massive frame filling the doorway. She paused, taking in the scene: Opal splayed on her back, trembling under Peridot’s relentless testing.

Peridot didn’t even falter. She threw Garnet a glance, her grin feral. “Ah! Perfect timing! Garnet—observe! Fusion subject under endurance calibration!”

Opal turned her head, groaning, her calm voice fraying. “Garnet—don’t—watch—”

Garnet’s lips curved into the faintest smirk. “I see you’re busy.” She folded her arms, leaning against the doorframe.

Peridot cackled breathlessly, hips slamming harder, tablet flickering with scribbled notes. “Yes! Data streaming in! Opal’s endurance exceeds Pearl’s reserve and Amethyst’s stamina combined! Garnet, you should take notes—your trial will come next!”

Opal gasped, her body trembling under the relentless rhythm, her voice breaking. “Peridot—hahh—too much—”

Peridot slapped her thigh sharply, her voice cold and precise. “Endurance means not too much. You will last until I declare the collapse point.”

Garnet’s smirk deepened as she watched, her shades hiding her eyes but not the slight tilt of her head. “You really do enjoy pushing them.”

Peridot hissed, her grin feral as she drove harder, Opal’s long legs trembling around her. “Enjoyment irrelevant—this is science!”

Opal’s composure crumbled further, her moans rising, hands clutching the hay. “Mmmhh—Peridot—please—”

Peridot’s visor fogged, her scribbles becoming jagged as her manic pace reached its peak. “Subject nearing threshold collapse! Endurance noted as exceptional but finite—haahhh—yes—YES!”

She slammed one last time, the sound echoing through the barn, Opal’s body shuddering as her voice broke into a sharp, guttural cry.

Peridot leaned back on her haunches, sweaty, visor askew, tablet clutched in one hand. “Phase Two: completed! Subject lasted seventeen-point-three minutes at increasing thrust intensity before collapse!”

Opal slumped back in the hay, chest heaving, sweat gleaming on her pale skin. Her serene mask shattered into a ruined, trembling smile.

Garnet chuckled low, shaking her head. “You really are something else, Peridot.”

Peridot pointed the stylus at her, eyes gleaming. “Don’t get smug. You’re next.”

Opal’s form shimmered, her long body dissolving into two smaller lights. Pearl and Amethyst reappeared, both flushed, their chests rising unevenly.

Amethyst collapsed onto her back with a wheeze. “Ughhh… that was brutal. I feel like my legs are jelly.”

Pearl adjusted her tunic, trying to gather her composure, though her blush betrayed her. “Well… that was certainly… thorough.”

Peridot hopped down from her perch, scribbling furiously on her tablet, visor askew. “Yes! Fusion endurance trial complete. Results spectacular.” She tapped her chin, her grin gleaming. “Next step: comparative fusion. Garnet must fuse with one of you. Double-fusion endurance test!”

Amethyst sat up, grinning wide. “Ohhh, hell yeah. You want big? Let’s go big. Garnet and me. Bring out Sugilite.”

Peridot’s head snapped up, eyes glittering. “YES! Unstable fusion! Maximum data potential!” She clapped her hands together, practically vibrating with excitement. “I demand—”

Pearl stepped sharply in front of her, hands raised, eyes blazing. “Absolutely not!”

Peridot froze, stylus in midair. “What?”

Pearl’s voice was sharp, cutting, but trembling with real fear. “Sugilite is dangerous. She’s unstable. We don’t summon her lightly.” Her eyes flicked toward Garnet, then back to Peridot. “If you want to run trials, you’ll do it safely. That fusion is off-limits.”

Amethyst rolled her eyes. “Pfft, you’re just mad I’d get to outshine you.”

Pearl’s hands clenched, her blush deepening. “This isn’t about me! It’s about control. Garnet and I form Sardonyx — stable, powerful, refined.” Her chin lifted proudly. “If Peridot must experiment, then I will be the one to fuse with her.”

The barn went quiet for a beat. Garnet tilted her head, her voice low. “Your call, Peridot.”

Peridot’s stylus wavered. For once, her manic grin faltered, replaced by a rare frown of thought. “Sugilite…” she murmured, pacing in a small circle. “Unstable. Potential destruction of barn. Data lost. Risk outweighs benefit…” She glanced up, almost reluctant. “…Pearl is correct. Sugilite inadvisable.”

Pearl blinked, startled. “You… agree with me?”

Peridot smirked faintly, though her tone stayed sharp. “Of course I agree. I’m a scientist, not an idiot. Risk assessment matters.” She pointed her stylus at Amethyst. “Sugilite may have value for later observation under controlled conditions. Not now.”

Amethyst pouted, flopping back into the hay. “Laaame.”

Peridot’s grin snapped back into place as she spun toward Pearl and Garnet. “So. Sardonyx. Yes. Elegant, articulate, theatrical. Perfect subject!” She tapped furiously on her tablet. “Fusion, commence!”

Pearl glanced at Garnet, her eyes bright despite herself. Garnet smirked, extending her massive hand. “Shall we?”

Pearl’s blush deepened, but she smiled, her fingers sliding into Garnet’s. “Yes. Let’s.”

Light flared, spinning them together, twisting until the barn filled with dazzling brilliance. Peridot shielded her eyes, cackling madly. “YES! YES! New fusion incoming—!”

The glow cleared, and Sardonyx stood tall, her four arms spread wide, her grin dazzling, her voice a rich, rolling laugh. “Ladies and gentlemen — and especially you, little green ringmaster — Sardonyx has arrived!”

She twirled her hammer once, then let it vanish with a flourish, bowing low in Peridot’s direction. “I hear you’ve been conducting trials. Well, aren’t you lucky? Tonight’s show features me.”

Peridot dropped her tablet in the hay, her grin feral, her visor fogging. “PERFECTION. Absolutely magnificent. Tall, articulate, composed. Pearl’s pride, Garnet’s power. Theatricality off the charts!” She scrambled for her stylus, scribbling in manic strokes. “Phase Three: Sardonyx endurance and humiliation trials!”

Sardonyx laughed, leaning down so her enormous face hovered close to Peridot’s. “Endurance? Humiliation? Darling, you’ll have to work hard to make me crack.”

Peridot’s grin sharpened into a cruel smirk. “Challenge accepted.”

The barn air still crackled with the afterglow of fusion as Sardonyx straightened, her massive grin dazzling, four hands planting on her hips. “Well, my eager little researcher, you wanted me stripped for your experiments, yes?”

Peridot clutched her tablet, smirking. “Correct. Disrobing for optimal access to all data points. Efficiency preferred.”

Sardonyx chuckled low, her voice rolling smooth like velvet. “Efficiency? My dear, I don’t do anything efficiently. I do it with style.”

With a snap of her fingers, her hammer shimmered back into existence, the colossal weapon planting itself into the barn floor with a heavy thunk. Sardonyx wrapped a long arm around the shaft, giving it a languid spin, her hips rolling with exaggerated grace. “You see, if we are to undress, let us undress properly. With spectacle.”

Peridot’s visor slipped down her nose as she froze. “Spectacle—? No, no, no. Unnecessary. Remove garments, assume position, commence Phase Three—”

But Sardonyx was already moving. She slid around the hammer like a dancer at a stage pole, her body arching, long legs twining as she laughed richly. “Darling, you’ve gone to such trouble, gathering subjects, cataloguing every inch, every taste. You deserve a show.”

Amethyst whooped from her hay bale. “Ohhh, yeah, this is what I’m talkin’ about!”

Sardonyx’s top pair of hands tugged at the fabric of her long tunic, pulling it inch by inch over her tall frame, hips rolling, thighs flexing. The garment shimmered away as she let it fall, her laugh echoing. “First, a little tease…”

Peridot’s stylus hovered in midair, her mouth opening, then snapping shut. “This is… inefficient. Completely irrelevant to data.”

But her wide eyes betrayed her.

Sardonyx twirled again, her lower arms sliding down the length of the hammer’s shaft while her upper pair lifted her hair, baring the long line of her neck. She winked down at Peridot, her voice playful and mocking. “Irrelevant? And yet, you’re staring.”

Peridot’s cheeks flared green. She scribbled furiously on her tablet to cover herself. “Observation: subject Sardonyx insists on unnecessary theatrics. Hypothesis: vanity component high. Conclusion: subject is a show-off.”

Sardonyx only laughed louder, hips swaying as her final garments dissolved, leaving her tall frame bare, her four arms stretching wide in a triumphant pose. “Voilà! Behold me in all my glory. Do try to keep up, little scientist.”

Peridot swallowed hard, her grin twitching into something breathless, manic, but softer at the edges. “Fine. Fine! You may be unnecessarily flamboyant, but… it was… an acceptable data acquisition method.”

Amethyst cackled, clutching her belly. “Hah! She liked it!”

Peridot whipped around, fists raised. “I did not! I simply—” she turned back to Sardonyx, cheeks blazing green, tablet clutched to her chest. “…find your form adequate for further testing.”

Sardonyx bent low, her massive grin inches from Peridot’s face, her four hands framing her hips in a dramatic flourish. “Adequate, she says. Oh, darling, you’re already undone.”

Peridot hissed, scrambling back onto her bench, stylus snapping into position. “Enough stalling! Subject prepared. Phase Three: full humiliation and endurance testing to commence!”

The barn was quiet now but for Peridot’s clicking claws as she circled her towering subject. Sardonyx leaned casually against her own hammer, now simply a stage prop, her grin dazzling, her form gloriously bare.

Peridot pointed her stylus like a blade. “Phase Three: systemic tasting and tactile assessment. Objective: identify and catalog unique fusion traits. Secondary objective: pierce through subject’s vanity with humiliating observation.”

Sardonyx chuckled low, her four arms folding elegantly across her chest. “Pierce my vanity? Darling, you’d need sharper tools.”

Peridot’s grin twitched. “We’ll see. On all fours, now.”

Sardonyx shrugged with a wry smirk, but complied. Her large body filled the center area of the barn, much as Opal had earlier.

Peridot started at Sardonyx’s feet, crouching low, fingers tapping lightly along her long toes. She leaned in and ran her tongue across the arch, scribbling immediately. “Feet: elongated compared to Pearl or Garnet individually. Taste: faintly metallic. Reaction minimal. Observation: subject’s feet are perfectly serviceable, but nothing remarkable. Functionally boring.”

Sardonyx raised a brow, smirking. “Boring? My dear, they’re exquisite. You’re simply too small to appreciate them.”

Peridot hissed through her teeth, scribbling harder. “Counter-observation: subject compensates with inflated ego.”

She moved up Sardonyx’s calves, squeezing them with her hands, slapping the side of one sharply so the sound echoed. “Calves: firm. Elegant musculature. Balance of Garnet’s strength and Pearl’s grace. Reaction to impact—” she smacked again, relishing the twitch it drew—“noted as positive. Observation: subject’s legs are begging to be bent open and used.”

Sardonyx laughed richly, her voice smooth. “You’re getting quite lewd with your notes, little scientist.”

Peridot flushed, scribbling furiously. “That’s… deliberate humiliation! Data phrased to embarrass!”

“Yet you’re the one blushing,” Sardonyx teased, lowering one of her arms to brush Peridot’s hair with her long fingers.

Peridot slapped the hand away, stomping up higher along her thigh. She spread her legs apart with sharp claws, leaning in to lap slowly at her core. Sardonyx’s smile faltered just slightly, her long body shivering.

Peridot pulled back with a smirk, licking her lips. “Vaginal entrance: exceptionally wet. Taste: complex. Pearl’s delicate tang layered with Garnet’s richer mineral. Observation: subject already eager to be filled, despite theatrical composure.”

Sardonyx’s grin returned, though her blush betrayed her. “Perhaps I simply enjoy being the center of your attention.”

Peridot hissed, slapping her inner thigh hard. “Correction: you enjoy being my subject.”

She moved beneath her, cupping Sardonyx’s breasts in both hands, squeezing, weighing them. She pinched her nipples between her fingers, tugging until the tall fusion groaned.

“Breasts: larger than Pearl’s, firmer than Garnet’s. Nipples highly responsive to stimulation.” She latched her mouth onto one, sucking hard, scribbling blindly with her free hand. “Observation: perfect for humiliating oral fixation.”

Sardonyx gasped, her grin slipping again before she caught herself, chuckling breathlessly. “You’re rather ruthless for someone so small.”

Peridot bared her teeth in a feral grin, shoving her visor up her nose. “Size irrelevant. Data absolute.”

Finally, she grabbed her chin and forcing her to meet her eyes. She licked slowly across her lips before pushing her tongue into her mouth, exploring greedily. When she broke the kiss, she wiped her mouth with the back of her hand and scribbled.

“Mouth: long tongue, highly versatile. Flavor rich. Observation: subject’s smug commentary will be easily muffled by forced oral servitude.”

Sardonyx’s blush deepened, her breath uneven now, though her grin stayed. “You do have a way with words, don’t you?”

Peridot hopped back, tablet raised like a trophy. “Phase Three: complete. Subject’s body catalogued, pride partially cracked. Further humiliation required.”

Peridot crouched behind Sardonyx, her tablet balanced in one hand, stylus poised like a dagger. The towering fusion arched her back, her grin still present, though her blush spread hot across her cheeks.

“Phase Four: posterior and secondary entrance examination,” Peridot announced, her tone sharp and clipped, but her smirk betraying how much she relished this part.

She grabbed Sardonyx’s ass in both hands, kneading and spreading the massive cheeks. “Gluteal mass: exemplary. Size—immense. Density—firm with perfect yield. Observation: subject possesses a truly perfect ass.” She slapped it hard, the crack echoing through the barn. “Reaction to spanking—” another slap, louder—“positive and immediate. Flesh jiggle ratio… delicious.”

Sardonyx gasped softly at the impact, her grin twitching at the corners. “Mmm—such crude language for a scientist.”

Peridot cackled, scribbling as she smacked her again. “Correction: deliberate degradation. Data phrased to embarrass. Subject’s proud façade cannot withstand extended spanking.”

She spanked in a steady rhythm, alternating cheeks, the barn filled with the crisp sound of palm on flesh. With each strike, Sardonyx’s body jolted, her composure cracking further, little groans slipping past her teeth.

Peridot leaned closer, her breath hot against the cleft of her ass. “Secondary entrance: visual inspection confirms tightness. Labeled for insertion trials later. Oral test commencing.”

Without hesitation, she dragged her tongue slowly from the base upward, pressing deliberately against the puckered ring. Sardonyx let out a low, startled moan, her long fingers digging into the hay.

Peridot smirked, scribbling without even looking. “Taste: rich, earthy. Sensitivity: extreme. Subject moans like a desperate whore when rimmed.”

Sardonyx’s grin cracked into an open-mouthed gasp. “Peridot—you—ahhh—”

“Say it,” Peridot hissed, slapping her ass again before diving back in with her tongue, swirling, probing. “Say what you are.”

Sardonyx’s laugh trembled, her voice breaking into moans. “You’ll… have to work harder than that—”

Peridot slapped her hard, five sharp smacks in a row, then shoved her tongue deep, relentless. Sardonyx’s moan shot higher, her composure faltering.

“Observation,” Peridot said breathlessly against her skin, “subject’s ego disintegrating under anal attention. Calling her a proud performer—” she smacked her again—“while treating her like a filthy hole—” another spank, her claws digging in—“is maximally effective humiliation.”

Sardonyx groaned low, her laugh dissolving into something ragged. “Nnnnhh—little tyrant—”

Peridot grinned viciously, pulling back just long enough to scribble, visor fogging. “Conclusion: Sardonyx’s ass is not only magnificent but her ultimate weakness. Additional spanking recommended.”

She raised her voice, sharp and commanding. “Admit it. Tell your audience what I’m doing to you.”

Sardonyx trembled, her arms shuddering as her grin cracked into something desperate. “…You’re… you’re using my ass…”

“Louder!” Smack.

“You’re spanking me—” smack “—and licking my asshole until I—ahhh—until I’m breaking—”

Peridot laughed ferally, her tablet glowing with her jagged notes. “Yes! Perfect! The proud Sardonyx reduced to ass-worship data!”

She spanked her again, tongue darting back in deep, her own breath ragged now as Sardonyx’s grand mask of composure slipped further, her moans echoing through the barn.

Peridot dug her fingers into Sardonyx’s ass cheeks, spreading her wide again, tongue darting back to that tight, trembling ring. Each deliberate swirl made Sardonyx’s proud posture falter, her laugh breaking into guttural gasps.

Then Peridot pulled back, her lips wet, her grin feral. Smack! Her hand cracked hard against the giant fusion’s ass. “Subject! Verbal acknowledgment required.”

Sardonyx’s breath shuddered, her grin shaky. “Acknowledgment…?”

Peridot’s visor gleamed as she adjusted them with a sharp snap of her wrist. “Describe it. Tell your audience what’s happening to you.”

She spanked her again, the sound ringing through the rafters. Sardonyx groaned, her long body shivering.

From the haybale, Amethyst snorted, chewing on her straw. “Ohhh, yeah. Make the fancy lady say it. I wanna hear this.”

Sardonyx tried for a chuckle, her voice ragged. “You’re… really insistent, aren’t you?”

Peridot spanked her harder, her tongue darting in deep for a long, obscene lick. Sardonyx gasped, her arms trembling.

“Say it!” Peridot barked. “Tell everyone what I’m doing to your ass!”

Sardonyx’s voice cracked, her grand timbre faltering into something raw. “You’re… mmmhh—you’re licking my asshole.”

Amethyst howled, doubling over with laughter. “Ha! Listen to her! All fancy speeches gone, just moaning about her ass—”

Peridot cackled, spanking her again, scribbling furiously with her free hand. “Excellent! Proud subject reduced to vulgarity! Continue description!”

Sardonyx panted, her long body shaking. “You’re… spreading me open… spanking me raw… humiliating me—”

Peridot’s grin stretched wider, her tongue darting back in, relentless, her visor fogging. Smack, smack, smack — three sharp spanks in rhythm with her licking.

Sardonyx cried out, her voice breaking. “You’re… treating me like nothing more than a hole for your tongue—ahhh—like a… like a filthy toy!”

Amethyst whistled low, her grin sharp. “Daaamn. Never thought I’d hear that outta Pearl and Garnet in the same breath.”

Peridot laughed manically into Sardonyx’s trembling flesh, pulling back just long enough to pant, “Data confirmed! Subject verbally acknowledges complete degradation! Vanity crumbling under sustained rimming and spanking!”

She smacked her one more time, savoring the way Sardonyx’s entire body jolted. “You’re magnificent, Sardonyx… but right now you’re just my ass-slut experiment!”

Sardonyx’s laugh finally shattered into a desperate moan, her proud voice ragged. “…Yes—your experiment—”

The barn filled with Amethyst’s laughter and Peridot’s cackling triumph as Sardonyx confessed her own humiliation.

Peridot strapped on her phallus attachment with a snap of leather, her grin sharp and greedy. “Phase Five: endurance testing—secondary entrance focus.” She climbed Sardonyx’s back like a manic little gremlin scaling a cliff, planting her boots firmly on the round swell of her ass. From her new perch, she smacked the massive cheeks with both hands. Smack, smack, smack.

“Observation,” she crowed, her visor slipping as her grin split wide. “Subject’s posterior doubles as ideal platform for researcher to stand upon.”

Amethyst wheezed from her haybale, tears in her eyes. “She’s literally using you as a step stool, Sardonyx!”

Sardonyx trembled, her arms shaking under her weight, her voice strained but still laced with bravado. “Even step stools can… hold queens, darling.”

Peridot snorted. “Not when they’re moaning like a whore.” She lined herself up, pushing the phallus against Sardonyx’s tight, trembling ring. The resistance made her hiss, her claws digging in for leverage. “Entry tight… resistant… but yielding under pressure.”

She shoved in hard, the phallus sliding deep. Sardonyx’s rich voice cracked into a guttural groan that echoed through the rafters. “Nnnhhh—Peridot—!”

Peridot scribbled furiously on her tablet even as she slammed forward again. “Reaction: immediate and catastrophic. Subject’s proud voice reduced to raw moan with single anal penetration. Hypothesis confirmed: secondary entrance is critical weakness.”

She gripped Sardonyx’s waist and began thrusting in sharp, relentless strokes, her little green body bouncing on the massive fusion’s back. “Endurance trial engaged at high frequency!”

Slap. Slap. Slap. Her hips smacked obscenely against Sardonyx’s ass, the sound echoing with every thrust.

“Admit it!” Peridot barked, her voice shrill and manic. “Tell everyone what you are!”

Sardonyx gasped, her grand laughter fraying into ragged moans. “…I’m… mmmhh—I’m your experiment!”

“Not good enough!” Smack.

“I’m—ahhh—I’m your filthy anal toy!”

Amethyst howled, clutching her stomach. “Oh stars, are you hearing this?!”

Peridot cackled, pounding harder, each thrust driving Sardonyx’s moans higher. “Yes! You’re my ass-slut! Say it again!”

Sardonyx’s arms buckled, her voice breaking into a scream. “I’m your ass-slut! Your filthy little hole to use—ahhh!”

Peridot’s visor fogged, her tablet shaking in one claw as she scribbled jagged notes between thrusts. “Endurance collapsing! Subject’s composure obliterated! Confessions achieved under anal penetration—YESSS!”

She slammed faster, bouncing gleefully on her perch, Sardonyx’s massive frame trembling beneath her. “You’re magnificent, Sardonyx—but right now you’re just my experiment’s slutty backdoor!”

Sardonyx’s laugh dissolved into raw, unfiltered moans, her proud veneer stripped away as she admitted each humiliating truth between gasps.

“Say it louder!” Peridot shrieked. Slap. Slap. Slap.

“I’m your slut—I’m your slutty hole—I’m breaking—”

Peridot rode her high and hard, a gremlin queen conquering a giant, her notes jagged with triumph as Sardonyx endured her most humiliating collapse yet.

Peridot slammed one final, brutal thrust, burying the phallus to its hilt. Sardonyx’s entire body shuddered under her, a strangled cry tearing from her throat.

Then, suddenly, Peridot yanked out, hopping down from her perch with a wicked little grin.

Sardonyx gasped, her four arms trembling as she collapsed forward onto her elbows, ass still quivering, empty and aching. “Wha—Peridot… why—”

Peridot adjusted her fogged visor, tablet glowing in her claws, her smirk sharp. “Phase Six: denial protocol. Subject pulled from threshold prior to orgasm.” She scribbled briskly, her tone cruel and clinical. “Observation: subject furious, desperate, trembling.”

Sardonyx twisted her head back, her grin ragged, breaking into something more needy. “You—you little tyrant—”

Peridot cut her off with a sharp smack across her ass. SLAP. “Quiet, slut! You don’t get to climax unless I allow it. You want release?” She leaned closer, her voice low and venom-sweet. “Then beg for it. Beg filthy.”

Sardonyx’s laugh cracked, trembling as she tried to hold her composure. “I… don’t beg.”

Peridot cackled, scribbling notes. “Observation: denial still not enough to crush subject’s vanity. Solution: increased humiliation.” She smacked her again, harder. SMACK! “Admit what you are! Call yourself my ass-toy, my filthy anal whore—make it disgusting!”

From the haybale, Amethyst leaned forward, grinning wide. “Ohhh this is good. C’mon, fancy lady, let’s hear you!”

Sardonyx’s body trembled under their eyes, her grand grin finally cracking into something raw, desperate. “I’m… nnnhhh—I’m your ass-toy… your filthy anal whore—”

Peridot slapped her again, standing proudly over her with her tablet raised like a trophy. “Not good enough! Louder! Lewder!”

Sardonyx moaned, her voice breaking as she sobbed the words out. “I’m your gaping little hole—your slutty ass to use however you want—please, Peridot, let me cum—”

Amethyst fell back howling with laughter. “YESSSS! She said it!”

Peridot’s grin turned feral, her visor sliding down her nose. “Now that’s data. That’s begging worthy of a reward.” She scribbled jaggedly. “Conclusion: Sardonyx’s pride annihilated. Subject reduced to desperate, lewd begging for anal release.”

She tapped the phallus against Sardonyx’s quivering cheeks, smirking down at her. “But whether I let you cum or not…” she hissed, “…depends entirely on how much more humiliation you’re willing to endure.”

Peridot hopped down from her perch on Sardonyx’s back, picking up another gleaming device from her charging station, smaller but humming with eager energy.

“Phase Seven,” she announced crisply, holding the new toy aloft like a prize. “Dual-penetration endurance trial. Both entrances filled simultaneously.” She turned her sharp grin on Sardonyx, whose long body still trembled in the hay. “But you only get it… if you can convince Amethyst to join.”

Sardonyx’s head snapped up, her eyes wide, her grand grin faltering into something desperate. “…Convince…?”

Peridot perched on her workbench like a goblin queen, tapping the stylus against her palm. “Correct. Use words, actions, whatever it takes. Seduce her, beg her, debase yourself for her. Otherwise, you’ll stay empty.”

Amethyst, sprawled on her haybale, raised a brow, smirking wide. “Well, damn. Didn’t think you’d throw me in, Peri.” She leaned forward, elbows on her knees. “Guess I’m the judge now, huh? This is gonna be good. I wanna hear the big fancy lady beg.”

Peridot cackled, brandishing her tablet like a scepter. “Yes! This is science! Sardonyx, convince her!”

Sardonyx’s four arms shook as she pushed herself up onto her hands and knees, hair falling in her face, her grin cracked into something desperate and trembling. She turned her head toward Amethyst, her voice low, ragged, stripped of grandeur.

“Amethyst… please. Fill me. Both of you at once. I want it. I need it.”

Amethyst leaned back, smirking, clearly enjoying this reversal. “Nah, not good enough. I wanna hear some real groveling. You’re the big, classy one, right? Make it dirty.”

Peridot smacked Sardonyx’s ass sharply, her own grin wild. “Yes! Filthy language required! More debasement!”

Sardonyx moaned, her voice cracking as she tried again. “I’ll be your slut, Amethyst… your whore… I’ll spread myself open for you. Fill my pussy, fuck me until I break—I’ll thank you for it—”

Amethyst’s grin widened, her eyes gleaming. “Ohhh, yeah. That’s more like it.” She stood, rolling her shoulders, swaggering toward the trembling fusion. “Never thought I’d see the day Sardonyx begged to get stuffed like a double feature.”

Peridot scribbled furiously, her voice manic. “Success! Amethyst persuaded! Subject’s debasement sufficient to recruit partner!” She tossed Amethyst the second phallus, smacking Sardonyx’s ass again. “Phase Seven: commence double-penetration endurance!”

Sardonyx shuddered, her composure gone, her voice breaking into desperate moans. “Yes—yes, please—fill me—use me both ways—”

Amethyst strapped the device on, smacking her ass once with a grin before lining herself up. “You asked for it, tall girl.”

Peridot grinned, snapping sharp orders like a field commander. “Subject, rotate to lateral position. Side-lying posture. One leg elevated for maximum access.”

Sardonyx obeyed, her enormous frame rolling onto her side with a heavy thud into the hay. She lifted one elegant leg, her hands trembling as she held it aloft, her massive body laid bare.

Amethyst let out a low whistle, smirking as she circled. “Damn. She looks good like this. All spread out, ready to get stuffed.”

Peridot climbed onto the hay beside her, strapping the phallus tighter with a little snap, visor sliding down her nose. “Phase Seven initiation: double-penetration endurance.” She smacked Sardonyx’s raised thigh with a sharp slap. “Subject exposed. Perfect.”

Amethyst knelt behind Sardonyx, lining herself up with her core. “Guess I’ll take the front door.”

Peridot straddled Sardonyx’s hip, positioning her phallus against the still-tight ring she’d tormented earlier. “And I’ll take the back.” She bared her teeth in a manic grin. “Simultaneous entry… commence!”

They thrust in together.

Sardonyx’s proud voice shattered into a scream, her body jolting as both holes were filled at once — Amethyst slamming deep into her pussy, Peridot driving the phallus hard into her ass.

“Yessss!” Peridot shrieked, scribbling jagged notes with one hand while pounding with the other. “Both entrances occupied! Subject’s moans catastrophic!”

Amethyst groaned, her grin wide as she slammed in rough and fast. “Ohhh, she’s tight, Peri! Can’t believe this classy lady’s taking both at once.”

Peridot laughed breathlessly, thrusting harder, her little green body bouncing gleefully against Sardonyx’s massive ass. “Observation: subject’s pride obliterated. Reduced to filthy double-stuffed toy!”

Sardonyx gasped, her four arms flailing, her leg shaking in the air. “Nnnhhh—both of you—stuffing me—splitting me open—ahhh—”

Peridot slapped her ass hard with her free hand, pounding faster. “Say it! Tell everyone what you are!”

Sardonyx’s voice broke into sobbing moans. “I’m your toy—your slut—your double-stuffed whore—ahhh, gods—”

Amethyst howled, thrusting faster, her hair flying. “Ohhh stars, that’s hot. Say it again!”

Sardonyx screamed it louder, her voice raw: “I’m your whore—your double-stuffed whore!”

Peridot cackled, scribbling furiously even as she fucked her mercilessly. “Data confirmed! Subject collapsed into complete verbal humiliation under DP endurance!”

The barn filled with the wet slap of hips, the sound of Peridot’s manic cackling, Amethyst’s ragged groans, and Sardonyx’s broken screams.

Peridot leaned down, her visor fogged, her grin feral. “You wanted a show, Sardonyx? This is it! Your grand finale—on your side, stuffed like a common whore!”

Amethyst spanked her thigh, her grin sharp. “Hell yeah! You’re our slutty center ring!”

Sardonyx’s leg buckled, her body trembling violently, her moans rising toward collapse.

Peridot gripped the base of her phallus with one hand, her little green body bouncing on Sardonyx’s trembling hip as she pounded into her ass; Amethyst slammed into her front, the wet sound of flesh on flesh filling the barn. Sardonyx’s enormous frame shook like a mountain under an earthquake, her leg still held high, her four arms clutching at the hay for purchase.

Peridot’s visor had completely slid off now, her hair wild, her stylus long forgotten in the hay. “Phase Seven—final stage—” she gasped between thrusts, “—subject approaching… total collapse!”

Amethyst’s grin was feral, sweat dripping from her temples. “She’s gonna blow, Peri. Listen to her.”

Sardonyx’s proud voice had dissolved into guttural cries, the words spilling out of her in fragments. “I’m—yours—I’m your double-stuffed slut—fill me—use me—please—”

Peridot leaned forward, her little claws digging into Sardonyx’s thigh as she drove the phallus as deep as it would go, each thrust timed with Amethyst’s in front. “Yes! Yes! That’s the confession I wanted. Now… your reward.”

She reached up and smacked Sardonyx’s ass hard, a sharp CRACK that echoed through the rafters. “Cum for your scientist. Cum for your little green master. Show me the data!”

Amethyst threw her head back, groaning, her hips slamming faster. “C’mon, tall girl. Let it go. Show us what you’ve got.”

That was the final push. Sardonyx’s scream tore through the barn, long and raw, her massive body arching off the hay as both entrances clenched around them. Her four arms clutched at the floor, her lifted leg trembling violently, toes pointed as a flood of release rolled through her. The proud, theatrical fusion came undone, crying out like she was falling apart and loving every second.

Peridot hissed, her grin feral, riding her through it. “Data complete! Subject Sardonyx—climax catastrophic! Endurance proven!” She smacked her ass one more time, then slowed, easing out carefully.

Amethyst groaned as she pulled free, collapsing back on her heels, a satisfied grin plastered across her face. “Whew. That was… wow.”

Sardonyx lay on her side in the hay, her chest heaving, her grin dazed and small now, but real. “That was… quite a show,” she murmured hoarsely.

Peridot hopped down from her perch, wiping sweat from her brow, her visor hanging from one hand. She crouched by Sardonyx’s head, tapping her stylus gently against her chin. “Reward phase complete. Subject’s climax achieved. Research… very satisfying.”

She reached out, almost shyly, and stroked one of Sardonyx’s massive hands with her tiny green fingers. “You performed… admirably.”

Sardonyx’s laugh was low and breathless, her eyes half-lidded. “You’re… relentless, little scientist.”

Peridot smirked, scribbling her last notes. “Relentlessness is science.”

The brilliant light of defusion filled the barn, the massive, trembling form of Sardonyx dissolving into two separate, shuddering bodies. Garnet landed on her feet with a soft grunt, her shades firmly in place, but her chest was rising and falling rapidly. Pearl collapsed into the hay with a gasp, her limbs splayed, her face a mask of dazed, overwhelmed ecstasy.

Peridot snatched her visor from the hay and shoved them onto her face, her stylus already flying across her tablet. “Defusion observed immediately post-climax! Fascinating! Synchronized collapse appears to catalyze separation!” She scurried over, peering down at them with unbridled scientific glee.

Garnet took a slow, deep breath, steadying herself. She adjusted her visor, a faint, knowing smirk playing on her lips. “That was… intense,” she rumbled, her voice a low vibration. “A unique experience. Being part of a fusion that was… taken apart like that. The lack of control was… illuminating.”

Pearl, meanwhile, could only whimper, pressing the back of her hand to her flushed forehead. Her whole body trembled with aftershocks. “Oh, my stars… I… I can’t… the things she said… the things we said…” Her voice was a thin, high thread of mortification and undeniable arousal.

Peridot’s grin sharpened. She zeroed in on Pearl, crouching right in front of her face. “Yes! The data from your fusion persona was exceptionally vivid, Pearl! Sardonyx’s verbal degradation under dual-penetration was a highlight of the entire trial series!” She tapped her stylus against Pearl’s cheek. “And you were a core component of that. Your repressed desires, given a grand, theatrical voice.”

Pearl flinched, her blush deepening to a brilliant azure. “I—that wasn’t—that was the fusion! Sardonyx is… more than the sum of her parts!”

“Precisely!” Peridot crowed. “And one of those parts is you. Your meticulousness, your pride… and the secret hunger festering beneath it.” She leaned in, her voice dropping to a conspiratorial, merciless whisper. “You enjoyed it. When Sardonyx begged to be called a ‘double-stuffed whore,’ a part of you, the real you, was screaming in agreement. Wasn’t it?”

Pearl let out a choked sound, trying to turn her face away, but Peridot’s hand gently, firmly, guided her chin back.

“Answer the query, Subject Pearl. For science.” Peridot’s eyes gleamed behind her lenses. “Admit it. You discovered something about yourself inside Sardonyx. Something filthy. Something slutty.”

Tears welled in Pearl’s eyes, but they weren’t tears of sadness. They were tears of shattering relief. Her carefully constructed composure, the fortress of her dignity, lay in ruins around her, and the freedom was terrifying and intoxicating.

Her voice was a broken whisper. “Yes.”

Peridot’s stylus froze. “Elaborate.”

Pearl squeezed her eyes shut, a shudder wracking her frame. “I… I liked it. I liked the loss of control. I liked… being reduced to something so base. So used.” The confession tore out of her, raw and honest. “When she… when I… was called those things, when I was filled so completely I couldn’t think… it was the most… the most liberating feeling I have ever known.” She finally opened her eyes, looking directly at Peridot, her gaze blazing with a shocking, newfound defiance. “There’s a slut inside me, Peridot. And she doesn’t want to be a proper Gem anymore. She wants to be your data.”

Peridot’s grin widened into something feral and utterly delighted. She didn’t scribble a note; she simply stared, absorbing the raw data of Pearl’s confession like a plant drinking sunlight.

“Liberation through degradation,” Peridot murmured, her voice laced with a scientist’s awe. “The dismantling of a millennia of repression via targeted humiliation and overwhelming physical stimulus. Your data is… beautiful, Pearl. Truly beautiful.” She leaned closer, her voice dropping to a razor’s edge. “This ‘slut’ you’ve discovered… does she crave more? Does she want to be the instrument of another’s awakening? To share this… glorious feeling?”

Pearl’s breath hitched. The idea was terrifying, transgressive… and it sent a fresh, hot jolt straight through her core. She bit her lip, her gaze flickering for a moment before hardening with a resolve that was entirely new. “She… she does.”

“Excellent.” Peridot straightened up, tapping her stylus against her chin. “Your combat student. The human girl, Connie Maheswaran. Disciplined, diligent, loyal. A will of iron, forged in training.” Her eyes glinted. “The perfect subject to test the hypothesis that even the most rigid self-control can be shattered by the right application of pleasure and shame.”

She looked down at Pearl, her expression one of pure, unadulterated ambition. “So, Pearl. Is your new self ready? Are you ready to help me corrupt your little protégé?”

The barn was silent, waiting for the answer. Garnet watched, her silence a heavy, approving weight. Amethyst’s smirk was a promise of chaotic assistance. And Pearl, with the ghost of Sardonyx’s ecstatic screams still echoing in her gem, felt the last vestige of her old self dissolve.

She looked Peridot dead in the eye, her voice clear and steady, no longer a whisper, but a vow.

“Tell me what to do.”
