Sadie lay sprawled on her bed, staring at the ceiling. The hum of her fan filled the silence, but she couldn’t shut off her brain. Every time she blinked, she felt it—the phantom weight of the invisible collar at her throat. It was like a ghost touch, warm and buzzing faintly against her skin, reminding her of what she’d done.

She’d given her mother’s name.

Her stomach twisted with guilt. Barb—tough, hard-working, forever tired from the mail route, forever alone since Dad had left—didn’t deserve to be handed over like a prize. But the other part of Sadie, the part still shaking from the orgasm Peridot had wrung out of her, whispered that maybe it wasn’t a betrayal at all. Maybe it was what Barb needed. Someone to grab her, strip her, make her feel something again.

*God, what have I done?* Sadie thought, pressing a pillow over her face. Her thighs pressed together involuntarily. *What if she actually likes it?*

The buzz came then.

It wasn’t loud, not even audible—it was a pulse, low and steady, thrumming directly into her nerves. Her breath hitched; her heart leapt. Her body responded before her mind caught up. She was on her feet, grabbing her hoodie, keys in hand. There was no hesitation. No question. Just the collar pulling her toward the barn.

By the time she stumbled into the cool night air of the barn, her pulse was pounding in her ears. She pushed the door open—and froze.

Barb was already there.

She was on her knees in the dirt, her postwoman’s jacket discarded, her hair messy and damp with sweat. The collar glowed faint green at her throat, pulsing in rhythm with her ragged breaths. And perched smugly on a crate, legs crossed, tablet in hand, was Peridot—glasses glinting as she observed her newest subject.

The synthetic phallus gleamed at her hips, still wet from use.

Sadie’s mouth went dry. “You—you already—”

Peridot looked up, grinning ear to ear. “Operation Barb was a success.” She scribbled a note with her stylus, then gestured to the trembling woman at her feet. “Subject collared, conditioned, and currently undergoing extended obedience testing.”

Barb whimpered softly, her hands clenched in her lap, her body betraying her even as her face burned red with shame.

Sadie’s stomach twisted again, but this time guilt was tangled with a wave of heat she couldn’t deny.

Peridot hopped down, trotting over to pat Sadie’s leg like a congratulatory coach. “Your intel was invaluable. Barb is already adapting well to her role.” She tilted her head, eyes glittering behind her glasses. “You came quickly when I buzzed the collar. Excellent compliance. Now…” Her grin widened. “…you get to watch your mother prove herself.”

Sadie’s breath hitched, her whole body trembling as Peridot guided her further inside, toward the sight of Barb kneeling, collared, already broken in.

The barn door boomed shut behind them, the sound echoing into silence. The place felt cavernous without the Gems—no laughter, no restless shifting, no hushed whispers. Just the smell of hay and wood, the hum of Peridot’s machines, and Barb’s shallow, uneven breaths.

Peridot clasped her little green hands together, glasses sliding low as she bounced once on the balls of her feet. “The others have been ordered to vacate,” she chirped. “Tonight is for human data collection only. Just you, me… and Barb.”

Sadie swallowed hard, eyes locked on her mother’s kneeling form. Barb wouldn’t look at her; she stared at the floor, fists clenched tight on her thighs. The collar glowed faintly at her throat, its steady pulse betraying every ragged breath.

Peridot hopped up onto her crate like a professor ready to lecture, crossing one tiny leg over the other. The synthetic phallus gleamed at her hips, still humming from its earlier use. “Allow me to narrate,” she purred, tapping her stylus against the tablet. “Operation Barb proceeded with efficiency.”

She pointed at Barb with a flourish. “First, I approached her on her route. Your mother is diligent, overworked, starved for attention. I intercepted her at the roadside with my usual charm.” Her grin was manic, teeth flashing. “She laughed. She called me a gremlin. That was her first mistake.”

Sadie’s stomach flipped. She couldn’t breathe.

“Second,” Peridot continued, “I pressed. I asked questions. Too many questions. She grew flustered.” She leaned forward, eyes glittering. “And then I tested her.”

Barb flinched at the word, cheeks burning, but Peridot’s smirk only sharpened. “I slipped the phallus attachment into place and pinned her right there against her little mail truck. She resisted—of course she resisted—but she moaned faster than you’d expect. She climaxed against the bumper before she admitted she wanted more.”

Sadie’s knees wobbled. “Peri…” she whispered, voice thin.

Peridot leapt down from the crate, strutting to where Barb knelt. She tipped the woman’s chin up with one finger. “By the time I brought her here, the collar was ready. I saved it for the brink, the way I did with you. Right before she shattered, I clamped it on.” She gave Barb’s chin a little pat, her grin sharp. “Now she’s mine.”

Sadie’s heart thundered, torn between horror and a heat that made her thighs press together.

Peridot turned to her, smirk wide. “And tonight, you’ll help me test her further.”

Sadie’s breath caught. “M-me?”

“Yes, you.” Peridot pushed Barb gently onto her back, then tugged Sadie closer by the wrist. “You’re family. You know her weaknesses. Her tells. And she knows yours. It will make the trial exquisite.”

Barb whimpered, trying to turn her face away, but the collar pulsed, forcing a shuddered moan from her throat.

Peridot’s glasses glinted as she gestured between them. “Subject Sadie Miller. Subject Barb Miller. Joint demonstration. Beginning now.”

She patted Sadie’s hip with her tiny hand, urging her forward. “Go on. Touch her. Let’s see how fast she breaks when it’s you.”

Sadie froze, trembling, staring down at her collared mother lying bare before her, Peridot’s grin sharp as a blade in the corner of her vision.

Sadie’s knees felt like water. She stood a few feet from Barb, the barn around them eerily quiet except for the soft hum of the machines and her mother’s uneven breathing. Peridot lingered just to the side, tablet balanced on her knee, stylus poised like a quill. She didn’t push yet—she just watched, glasses glinting.

Sadie took a step forward, then another, until she was close enough to kneel. The boards were cool under her skin. She reached out tentatively, fingers hovering above Barb’s arm but not touching yet.

“Mom…” her voice cracked. “Look at me.”

Barb’s eyes fluttered open. They were glassy, but there was still a flicker of the tough, tired mail carrier behind them. “Sadie…” she whispered, cheeks burning. “I didn’t… I didn’t know you’d be here.”

“I didn’t know you’d be here either,” Sadie admitted, her throat tight. She finally let her fingers graze Barb’s arm—light, trembling touches. “Do you… do you want this? Are you okay?”

Barb let out a shaky laugh that turned into a moan when the collar pulsed faintly at her throat. “It’s insane,” she whispered. “It’s humiliating. But… it feels good. God help me, it feels good. I haven’t been touched like this in years.” She closed her eyes, biting her lip. “And I know you’ve been lonely too. You don’t have to pretend.”

Sadie’s heart squeezed. She leaned down a little closer, her forehead brushing Barb’s. “I didn’t mean to sell you out,” she murmured. “I thought… maybe it would help you. And now here you are.”

Barb laughed softly again, this time without bitterness. “Maybe you’re right,” she said hoarsely. “Maybe this is what I needed.”

Peridot’s stylus clicked rapidly against her tablet, but she stayed silent, letting the scene play. Her little smile was sharp, but her eyes glowed with something almost like curiosity. She wanted to see what humans did with the bonds she’d forged.

Sadie drew a long breath. “If I touch you… if I do what she wants… you won’t hate me?”

Barb shook her head, hair brushing her cheeks. “No, baby,” she whispered. “I won’t hate you. Just… don’t be gentle. It’s worse when you’re gentle.”

The words hit Sadie like a current. She closed her eyes, pressed a kiss to her mother’s temple—hesitant but real—and then let her hand slide down Barb’s arm to her side, following the curve of her waist. Barb shuddered under the touch, a low moan escaping her lips.

Peridot scribbled something on the tablet, her grin widening. “Fascinating,” she murmured. “Maternal bond overridden by shared submission cue. Proceed.”

Sadie swallowed hard. Her palm slid lower, fingers tracing the edge of Barb’s hip. She leaned in just enough for her voice to be a whisper in her ear. “Tell me if you want me to stop.”

Barb moaned again, arching slightly into her hand. “Don’t stop,” she whispered back. “Please.”

Sadie’s breath shuddered out of her. She looked up at Peridot once, saw the manic little smirk, the phallus glowing faintly at her hips, and then looked back down at her mother. Her hand slid slowly over the soft swell of her belly, mapping it the way Peridot had mapped hers, her thumb brushing just under her waistline.

Barb gasped, her eyes fluttering closed, the collar pulsing brighter.

Peridot’s voice was a low purr now. “Excellent. Let’s see how far you’ll take her.”

Sadie pressed her palm fully against Barb’s stomach, feeling the warmth of her skin. “I’m here, Mom,” she whispered. “I’m not going to hurt you. Just… tell me what you need.”

Barb’s eyes opened, hazy but pleading. “Touch me,” she murmured. “Touch me like she does.”

Sadie drew a long, shaking breath. Her palms were damp against Barb’s skin, but the warmth there, the tiny tremors under her fingers, began to push past the knot of guilt in her chest. Her mother wasn’t fighting. She wasn’t begging Peridot to stop. She was trembling, breathing faster, and her eyes when they flicked up to meet Sadie’s were almost soft.

“Okay,” Sadie whispered. “Okay…”

She slid her hands down the line of Barb’s waist. Barb whimpered softly, a sound of shame and release all at once.

Peridot scribbled furiously on her tablet, glasses flashing as she watched. “Subject Sadie Miller initiates physical contact with Subject Barb Miller. Maternal bond producing complex guilt-arousal feedback loop. Fascinating.”

Sadie ignored the words. Her fingers trembled as they spread across Barb’s belly, down over the slight swell of her hips, then around to her thighs. Barb’s breath caught when Sadie’s thumbs brushed the inside of them, her legs parting a fraction without prompting.

Sadie bent a little, her forehead brushing Barb’s hairline again. “It’s okay,” she murmured. “It’s just us.” She dipped her head, pressing a kiss just below Barb’s jaw—tentative at first, then firmer when Barb moaned softly.

Barb whispered, eyes closing, “Don’t hold back…”

Peridot’s stylus clicked rapidly. “Verbal consent from Subject Barb Miller. Submission intensified in presence of related submissive. Hypothesis confirmed.”

Sadie swallowed hard. She let her mouth trail from Barb’s jaw down to her neck, kissing and sucking lightly, tasting the salt of her skin. Her hands slid lower, cupping the curve of her hips, then skimming along the tops of her thighs. Barb trembled, her breath coming out in shaky gasps, her fingers digging into the floor.

“You’re beautiful,” Sadie whispered, surprising herself. “I didn’t know you still wanted… this.”

Barb laughed softly, broken and breathless. “I never stopped wanting. I just stopped hoping.”

Sadie’s stomach flipped at that. She slid one hand between Barb’s legs at last, palm cupping her mound, fingers tracing gentle, testing circles. Barb moaned, hips shifting forward.

Peridot leaned slightly closer, her voice low and delighted. “Subject Sadie Miller now administering direct stimulation. Subject Barb Miller displays heightened responsiveness. Cross-generational erotic imprinting—humans are so interesting.”

Sadie blushed hard at Peridot’s commentary but didn’t stop. She pressed her thumb against the spot where Barb was warmest, circling slowly, the way Peridot had done to her. Barb moaned louder, her head tipping back, collar glowing faintly at her throat.

“Tell me what you want,” Sadie whispered.

Barb gasped, her voice cracking. “More… touch me more.”

Sadie slipped along the folds of her mother’s pussy. She stroked gently at first, then firmer when Barb’s hips jerked. Barb clutched at the floorboards, a low moan spilling from her lips.

Peridot’s stylus hovered mid-note, her little grin bright and sharp. “Observation: Subject Barb Miller responds more quickly to direct familial stimulation than to standard predation. Data extremely valuable. Proceed.”

Sadie didn’t look up. She pressed closer, her breath hot against Barb’s neck, her fingers moving in slow, steady circles while her other hand kneaded the softness of her hip. Barb’s moans grew louder, shuddering, her body arching into the touch.

“I’ve got you, Mom,” Sadie murmured. “I’ve got you.”

Barb’s hand twitched up, brushing Sadie’s arm, her nails biting gently into her skin. “Yes… please… don’t stop…”

Sadie shifted lower, sliding between Barb’s trembling thighs. Her breath was shallow, her fingers still stroking, but her eyes flicked up nervously one last time. Barb gave her the faintest nod, her lips parting on a moan, the collar pulsing at her throat as if to punctuate the consent.

Sadie leaned in and pressed her mouth to the soft skin of her inner thigh, kissing gently at first, then again higher, tasting the salt of her sweat. Barb whimpered, her hand twitching against the floorboards, nails scraping wood.

“Good,” Peridot noted from her crate, scribbling furiously. “Subject Sadie transitions from manual stimulation to oral sampling without direct order. Indicates high adaptive instinct. Subject Barb’s respiration spikes thirty percent when contact involves tongue rather than hand.”

Sadie flushed hard, the words stinging like a slap, but she didn’t stop. She licked higher, slowly, until her tongue brushed the core of her mother’s heat. Barb cried out, hips jerking, her whole body shuddering.

Peridot giggled sharply, glasses sliding low. “Note: when serviced by her own daughter-subject, Barb’s collar pulse intensifies *independently of my input.* Remarkable. Guilt and arousal are feeding into a feedback loop. Humans are endlessly fascinating.”

“Peri—!” Sadie gasped against her, voice muffled, face burning red. “Could you *not* say it like that?”

“Why?” Peridot tilted her head, her smirk wide. “It’s true. Data is beautiful. And humiliating data is *even more valuable.*”

Barb moaned again, louder, her thighs trembling as Sadie’s tongue moved in small, steady circles.

Peridot’s stylus clicked. “Observation: Barb’s arousal is heightened by embarrassment. Especially when the bond between her and Sadie is verbally acknowledged. Hypothesis: taboo accelerates surrender.”

Sadie whimpered into her, half from the taste and half from the sting of Peridot’s commentary, but her mouth kept moving, lips sealing around Barb’s clit as her tongue flicked rapidly. Barb bucked, her hands flying up to clutch at her hair, pulling her closer with desperate strength.

“Yes—don’t stop—please don’t stop—” Barb’s voice cracked, raw with need.

Peridot leaned forward, eyes gleaming. “Ha! Excellent. She begs faster when Sadie is the one performing the act. The psychological fracture point is close.”

Sadie’s face was crimson, her whole body shaking, but she pressed harder, sucking firmly as her tongue circled faster. Barb sobbed, her hips jerking up, the collar glowing bright at her throat.

“NOW,” Peridot barked suddenly, leaping off her crate, eyes wild. “Now she breaks! Sadie, hold her—make her admit it!”

Sadie lifted her mouth just enough to gasp, “Mom—say it—” then sealed her lips back over her, tongue relentless.

Barb screamed, climax ripping through her body, every muscle tensed. Her words tore from her throat between sobs: “Yes—I’m hers—I’m Peridot’s—oh god—yes—!”

The collar flared blindingly, then steadied to a low, satisfied hum.

Peridot cackled, manic and triumphant, scribbling in jagged strokes on her tablet. “Subject Barb Miller: fully broken. Joint trial a COMPLETE success!”

She spun in a circle, laughing high and shrill, while Sadie slumped against Barb’s thighs, trembling, face wet, both women breathing raggedly in the aftermath of their shared collapse.

Peridot didn’t give either of them time to recover. She skittered across the barn, clacking on the tablet as she adjusted something on her belt. With a hiss of energy, a second phallus shimmered into being at her hips, twin shafts glowing faint green, humming like live wires, placed just far enough apart to two people at once.

“Phase two!” she declared, her grin wild. “Dual-subject penetration trial. We’ll test simultaneous response and… hm, bonding reinforcement between participants.” Her glasses slid low, eyes gleaming. “Perfect.”

Sadie blinked up, still trembling from what she’d just done, her face flushed and damp. “You—you can run *two* at once?”

Peridot cackled, hopping lightly back onto her crate to show off the humming twin attachments. “Of course I can. I *invented* them. And you’re going to help me test them.”

Barb lay sprawled on the floor, still panting, sweat beading her chest, collar pulsing faintly at her throat. She groaned, eyes half-shut. “Oh god… I can’t—”

“Yes you can,” Peridot cut in sharply, pointing her stylus like a conductor’s baton. “Both of you, on all fours. Side by side.”

Sadie hesitated, but the collar’s steady buzz nudged her forward, guiding her until she was kneeling next to Barb, their shoulders brushing. She glanced sideways, breath ragged. Barb turned her head just enough to meet her eyes, cheeks flushed deep crimson. There was no resistance left—only resignation, and something like relief.

Peridot bounded down and stalked behind them, crouching to eye her subjects like a jeweler inspecting gems. “Excellent positioning.” She smirked, gripping her tablet tighter. “Sadie on the left. Barb on the right. Mother and daughter, both with big, beautiful asses. Let’s begin.”

She pressed forward, guiding each shaft into them at once. Both women cried out in unison, voices overlapping—one raw with new sensation, the other hoarse from already being broken. Their hands dug into the boards, shoulders shivering against one another as their pussies filled.

Peridot gasped, her little body trembling with the dual feedback. “Yesss… synchronized responses!” She thrust shallowly at first, experimenting with rhythm, then harder, her grin stretching. “Oh, this is *incredible.* Subject Sadie and Subject Barb clench differently—yet when stimulated together, their responses converge. It’s like tuning two instruments!”

Sadie moaned helplessly, arching into the thrusts, her eyes squeezed shut. “Oh—oh god—it’s too much—”

Barb whimpered beside her, tears streaking her cheeks. “Yes—please—don’t stop—”

Peridot giggled, sharp and shrill. “Don’t *worry*, I won’t! This is vital research!” She scribbled one-handed on her tablet even as her hips drove forward, both shafts plunging deep in tandem.

The two women pressed closer together, their bodies brushing, shoulders and thighs trembling against each other. Sadie turned her face, lips brushing Barb’s cheek, whispering through a sob, “We’re in this together, Mom.”

Barb gasped, her forehead knocking lightly against hers. “Together…”

Peridot’s stylus clattered to the floor as her movements grew more manic, her laughter filling the barn. “Familial bonding confirmed! Collars synchronizing!”

Mother and daughter cried out again, voices overlapping, the collars at their throats glowing brighter as Peridot drove harder, faster, twin phalluses humming in unison. Their moans rose higher, their hands clutching the floor and then, finally, each other.

Peridot shrieked with delight. “Perfect! PERFECT! They climax as one!”

The barn echoed with their screams as the collars pulsed in sync, sealing them both tighter under Peridot’s ownership, their bodies collapsing together in a tangled heap when it was over.

Peridot wiped her glasses with the hem of her shirt, her grin still wild, and tapped her tablet with a flourish. “Phase two a complete success. Bond reinforced. My data is flawless.”

She hopped up onto their trembling backs like a conqueror claiming her spoils, her tiny feet pressing into their bare skin. “You’re mine now. Both of you. Forever.”

Peridot hopped lightly off their backs once their trembling subsided, stylus already back in hand, glasses sliding down her nose. She crouched beside them like a jeweler examining two rare stones laid out on the floor.

“Phase three: comparative analysis,” she announced, tapping the tablet. “Two human subjects, same genetic line, different ages, different builds. Time to catalog.”

Sadie flinched, still trying to catch her breath, while Barb groaned, her arms buckling under her. Neither resisted as Peridot’s small hands pressed and prodded their trembling, vulnerable forms.

She started with Sadie’s shoulder, pinching the soft flesh between her fingers. “Younger subject has more elasticity here. Tissues spring back faster.” She moved her hand across to Barb, squeezing firmly. “Older subject shows decreased resilience, but…” she leaned down, licking a stripe along Barb’s shoulder, “…saltier sweat content. Taste more complex.” She scribbled furiously.

Sadie blushed furiously, covering her face with her arm. “Peri, do you have to *say* everything out loud?”

“Of course!” Peridot chirped, utterly oblivious. “That’s how I make accurate records.” She grabbed Sadie’s wrist, pressing her thumb to her pulse. “Rapid heartbeat still present. Indicates arousal hasn’t fully subsided. Potential for re-stimulation.”

Then she slid lower, pressing her hands to both women’s hips, kneading experimentally. “Subject Sadie’s hips: broader than expected, strong fat distribution. Ideal for leverage. Subject Barb’s: even broader, surprising balance of fat and muscle tone, likely due to active occupation. Better tactile contrast.” She leaned down and bit lightly at Barb’s hip, grinning when she yelped. “And more sensitive here.”

She turned her focus lower still, hands running down their thighs, one then the other, comparing muscle tone and reaction. “Sadie has stronger trembling response in inner thighs, while Barb’s calves twitch faster under tongue stimulation.” She licked experimentally at the back of Barb’s knee, then at Sadie’s, humming in delight at the difference.

Finally she slid behind them both, tilting her head as if she were lining up two canvases. Her little hands cupped their asses, squeezing, smacking each in turn, listening to the different sounds of flesh on flesh. “Heavier bounce from Sadie, sharper recoil from Barb. Both satisfying. Both useful.” She scribbled, then crouched lower, tasting one and then the other with exaggerated focus. “Sadie’s sweeter. Barb’s muskier. This is EXCELLENT data!”

Sadie buried her face in her arm with a muffled groan. “You’re killing me…”

Barb shuddered, voice hoarse. “She’s… thorough, I’ll give her that…”

Peridot cackled, hopping back to her feet, her stylus raised like a victor’s blade. “Comparison complete! Both subjects unique, both valuable. My human collection is progressing flawlessly.”

She adjusted her crooked glasses, manic grin stretching wide as she looked down at the two spent women sprawled side by side. “Next,” she purred, “we’ll test endurance.”

Peridot gave them no chance to collapse into stillness. She bounced to her machines at the far wall, claws tapping furiously across her console. With a triumphant chirp, she yanked free a long, gleaming device—one of her favorite prototypes. A double-sided phallus, humming faintly with green light, flexible but solid, its twin ends glowing with energy.

She turned, glasses slipping down her nose as she grinned wickedly. “Phase four: endurance trial. Tandem stimulation. Duration test until collapse.”

Sadie blinked at the sight of it, still breathless, sweat clinging to her skin. “You’ve gotta be kidding me—”

Barb groaned, her voice rough. “She’s… not kidding.”

Peridot cackled, strutting forward with her prize. “On your backs. Side by side. NOW.”

The collars pulsed, and neither woman resisted. They rolled onto their backs, assess brushing, both trembling but obedient. Peridot crouched between them, positioning the double phallus, nudging one end toward Sadie, the other toward Barb.

“Spread,” she ordered. “Take it together. Show me how strong you are.”

Sadie whimpered but obeyed, her thighs parting. Barb mirrored her, lips trembling as the collar thrummed.

Peridot pressed, sliding the glowing shaft into both at once. Their cries overlapped, sharp and raw, as their assholes stretched around the device. Peridot giggled shrilly, clapping her hands once. “Yes! Look at you—stuffed end-to-end like the specimens you are!”

She crouched at their heads, peering down gleefully. “Tell me what you are. Say it while you’re impaled together.”

Sadie’s face burned scarlet, her voice breaking. “I’m—your subject—”

Barb sobbed, clutching the boards. “I’m your toy—your property—”

Peridot howled with delight, stylus scratching notes as she shoved the base of the device, making it pump shallowly into both at once. Their cries rose in tandem, feet flying to clutch at each other’s soles for support.

“Perfect! PERFECT!” Peridot shrieked. “Mother and daughter, rutting like animals under my command!” She smirked, leaning close enough to whisper. “Embarrassed? You should be. But look at you—you can’t stop. You love it.”

Sadie whimpered, her eyes squeezing shut. “God—yes—I can’t stop—”

Barb moaned louder, hips lifting into the thrusts. “I do—I love it—”

Peridot shoved harder, laughing manic and cruel. “Pathetic! You should be disgusted—but instead you’re dripping around my invention like sluts in heat. I OWN YOU!”

The barn echoed with their cries, their voices breaking in rhythm as the double phallus drove them toward shuddering peaks. Their collars pulsed brighter, syncing, the glow painting their throats.

Peridot’s grin was feral as she scribbled furiously on her tablet. “Observation: endurance collapsing rapidly under humiliation reinforcement. Both subjects degrading beautifully.”

She threw her head back, shrieking with joy as Sadie and Barb broke together, screaming her name, the device sliding between them as their bodies convulsed in tandem.

They slumped side by side, gasping, clinging to each other in the aftermath.

Peridot stood over them, glasses crooked, stylus tapping against her teeth. “Endurance trial: complete. Result: utter failure of resistance. And that,” she purred, crouching to stroke their damp faces with one small hand, “is my perfect success.”

Peridot wasn’t satisfied with one round, not when her tablet was hungry for data and her invention hummed eagerly in her claws. The first climax left Sadie and Barb trembling, bodies slack and gasping—but their collars glowed steady, pulsing with her will.

“Again,” she hissed, pressing the device deeper, grinding it between them until both women arched off the floor, groaning in exhausted shock. “Endurance requires repetition. You’ll keep going until your bodies collapse.”

“P-Peri—” Sadie whimpered, her thighs trembling violently. “I can’t—”

“Yes you can,” Peridot snapped, her eyes glittering, grin feral. “The collar will drag you past what you think are limits. You’ll learn your true capacity tonight.”

Barb sobbed, shaking her head, but her hips bucked anyway, body betraying her. “Oh god—she’s right—I can’t stop—”

Peridot giggled shrill, forcing the device to pump with short, brutal strokes. “Exactly! You don’t *stop* until I tell you. You break again and again, and every time, you’ll beg me for more.”

The barn filled with cries and sobs as she drove them to a second peak. Sadie screamed hoarse, clinging to Barb’s hand; Barb moaned raggedly, pressing her forehead to Sadie’s shoulder. Their bodies shuddered in unison, another climax tearing through them as the double phallus glowed bright.

But Peridot didn’t relent.

“Again!” she shrieked, manic. “Push through! Collapse together!”

A third time. Then a fourth. Each release weaker, more desperate, until their voices cracked and their nails clawed weakly at the boards. Peridot’s grin never faltered, stylus scratching furious notes as she timed each orgasm, each tremor, each collapse.

By the fifth, their bodies could barely respond, just trembling reflexively under the relentless thrusts. Their cries dwindled to whimpers, their eyes glassy and wet. At last, Peridot hissed a command and the device withdrew, glowing faintly before clicking dormant in her hand.

“Collapse achieved,” she said breathlessly, her glasses sliding down her nose, hair sticking to her damp forehead. “Subjects rendered unconscious within safe parameters. Endurance trial… *spectacularly successful.*”

She crouched between them, tiny hands patting their slack cheeks almost fondly. “Good humans,” she murmured. “So obedient. So broken. So mine.”

With a little effort, she rolled them closer together until their limp bodies pressed side by side on the floor. Instinct took over where consciousness had failed—Sadie curled into Barb, Barb’s arm draped weakly over Sadie’s back. Their collars pulsed in sync, steady and soft.

For the first time in years, they slept together like that—a mother and daughter who had been distant, now clinging like they’d never let go again.

Peridot perched on her crate, chin resting on her tablet, watching them with her sharp little grin. “Adorable,” she muttered to herself. “Conditioning breeds unity. They’ll wake closer than ever… and bound to me forever.”

She scribbled one last note, then leaned back, satisfied. “Chapter complete.”
