The barn was still heavy with the scent of hay and sweat when Peridot tapped her stylus against the edge of her tablet, pacing in sharp little circles. Jenny sprawled on the workbench, collar faintly thrumming at her throat, one leg dangling, smirk glued to her lips. Peridot had fucked her all night, and she’d never felt more satisfied. She turned her head and watched Peridot pace like a cat chasing her tail.
“You’re scheming already,” Jenny said, voice raspy from the night before.
Peridot’s grin cut wide, visor gleaming. “Of course I am. You were a flawless conquest. But one sister is merely half of the Pizza equation. For true control, I require both.”
Jenny raised a brow, pushing herself upright. “You mean Kiki?”
Peridot nodded sharply. “Correct. The diligent one. The workhorse. The jogger.” She tapped her tablet and a shaky little doodle of Kiki appeared, complete with sweatband and sneakers. “Unlike you, she doesn’t crave rebellion. She craves… relief.”
Jenny laughed, rubbing at the collar on her neck. “You’re not wrong. She’s always stressing about the shop, about the family, about everything. She could use some fun.”
Peridot clapped her hands, boots squeaking on the barn floor. “Exactly! Your insight is invaluable. You will be my ‘in,’ Jenny Pizza. You will lead me to your sister, soften her guard, and then…” she smirked, stylus tapping against her teeth, “I’ll do the rest.”
Jenny tilted her head, still smirking. “You want me to sell out my own twin? Harsh.”
Peridot climbed back onto the workbench, kneeling close, her little green fingers brushing along Jenny’s collar. The hum sparked, making Jenny shiver. “Not selling out. Liberating. You’ve already felt the collar’s gift. Don’t you want your sister to feel that too?”
Jenny groaned, rolling her eyes. “You’re evil. And maybe a little right.”
Peridot cackled triumphantly, scribbling furiously on her tablet. “Phase one: set up encounter at the restaurant. Subject Jenny will be present to normalize my appearance and reduce suspicion. Subject Kiki’s curiosity will be piqued. Subject Peridot will deploy charm, science, and overwhelming charisma!”
Jenny smirked. “Charm, huh? That’s what you call what you do?”
Peridot shot her a glare, then softened it into a grin. “It worked on you.”
Jenny’s laugh echoed in the rafters, low and fond. “Yeah. Guess it did.”
—–
The bell above the glass door jingled as Peridot strutted into Fish Stew Pizza, her tablet tucked smugly under her arm. The lunchtime rush was long past; the restaurant was quiet, just the hum of the soda machine and the faint sizzle of oil in the kitchen.
Behind the counter, Kiki Pizza looked up from the register. Her hair was tied back, apron crisp, a pencil tucked behind one ear. She blinked at the tiny green stranger, then smiled warmly out of habit. “Hey there! Welcome to Fish Stew Pizza. Just you today?”
Peridot adjusted her visor, pushing it up her nose with a sharp little shove. “Correct. Just me. The perfect time. Optimal.”
Kiki tilted her head, still smiling. “Optimal?”
“Yes,” Peridot said, slamming her clawed hand down on the counter with far too much drama. “Optimal because you are here, alone, ready for my data collection!”
Kiki blinked, then laughed nervously. “Uh… data collection? You sound like my friend Sadie. She’s always talking about her new diet app.”
Peridot puffed up indignantly, hands on her hips. “I am no mere app! I am Peridot: genius, inventor, conqueror of experiments!” She gestured wildly, nearly knocking a napkin dispenser off the counter. “And today, you, Kiki Pizza, will be my next subject.”
Kiki froze, pencil sliding out from behind her ear and clattering onto the counter. “Wait—how do you know my name?”
At that moment, Jenny strolled out from the back, still wearing her jacket, a soda cup in her hand. She leaned lazily against the doorway, smirk curling her lips. “Relax, sis. She’s with me.”
Kiki’s brows shot up. “With you?!”
Jenny shrugged, sipping her drink. “We met at the arcade last night. She’s… different. Thought you’d get a kick out of her.”
Kiki sighed, rubbing her forehead, but her smile returned — fond, exasperated. “Jenny, you can’t just bring your weird friends here without warning me.”
Peridot bristled, stomping one little boot. “Weird?! I am extraordinary!”
Jenny chuckled, shooting Kiki a look. “Told you. She grows on you, though.”
Kiki rolled her eyes but laughed softly. “Alright, alright. What can I get you, Peridot, was it? A slice, maybe some garlic knots?”
Peridot tapped her chin thoughtfully, stylus ready. “Yes. Food first. Then… experimentation.”
Jenny smirked, leaning closer to her twin. “Told you she’s a trip.”
Peridot picked out a slice, not particularly caring much about what type of pizza it was. Kiki smiled politely as she took her order. She ducked into the kitchen, her voice calling back over the hiss of oil: “One slice, coming up!”
Peridot perched herself awkwardly on one of the counter stools, tablet clutched in her lap, her little boots swinging. She tapped her stylus against the wood with nervous, excited energy, eyes darting around the empty restaurant. Jenny leaned on the counter, sipping her soda, smirk plastered across her face.
“You’re wound up,” Jenny teased, her voice low.
“I am focused,” Peridot corrected, puffing her chest. “This is phase one of sibling acquisition. If I can breach the responsible one, the Pizza fortress will be mine.”
Jenny snorted into her straw. “You sound like you’re planning a heist.”
“I am planning a heist,” Peridot whispered, leaning close, visor crooked. “A heist of the heart.”
Jenny choked on her soda, laughing hard. “Oh my god. You’re actually gonna say that to her, aren’t you?”
“Of course,” Peridot said smugly, straightening her visor. “It is the pinnacle of romance.”
Kiki returned just then, balancing a plate with a slice of steaming pizza and a small dish of garlic knots. She set them on the counter with a smile. “Here you go, Peridot. One of each. On the house — you’re Jenny’s friend, after all.”
Peridot’s grin went sharp. She picked up the slice in both hands, staring at it intently before taking a large, awkward bite. Cheese stretched in a stringy arc as she chewed far too loudly, then jabbed her stylus at Kiki.
“Excellent. Starchy. Cheesy. Truly… intoxicating.” She narrowed her eyes, leaning forward across the counter. “Almost as intoxicating as you.”
Kiki blinked, then laughed, cheeks warming. “Oh wow, you’re… blunt, huh?”
Jenny propped her chin on her hand, smirk curling. “Told you. She’s got no filter.”
Peridot smirked, tapping her stylus against her lips. “Why filter brilliance? Your hair glistens like oil on the sea, your eyes reflect light with uncanny refraction, and your—” she paused, scanning Kiki up and down with the intensity of a scanner beam, “—symmetry is… statistically improbable. In a good way.”
Kiki’s laugh came quicker this time, her shoulders shaking. “Okay, wow. That’s definitely the weirdest compliment I’ve ever gotten.”
Jenny grinned. “She means it, though. Don’t let her science-babble fool you. She’s into you.”
Kiki swatted at her twin’s arm, rolling her eyes, but her smile lingered. “Jenny, seriously…” She turned back to Peridot, still laughing softly. “You’re really something, you know that?”
Peridot scribbled furiously on her tablet, muttering under her breath. Subject Kiki Pizza: initial defenses lowered by humor response. Positive feedback to direct flattery. Probability of success: high.
Then she looked up again, her grin twitching wider. “I am not just ‘something.’ I am everything. And you, Kiki Pizza, should consider yourself fortunate that my brilliance has chosen you.”
Kiki laughed again, shaking her head. “Oh my god. You’re ridiculous.”
Jenny leaned back, smirk smug as ever. “Told you she grows on you.”
Peridot dabbed at her lips with a napkin like she’d seen humans do, though she held it between two stiff fingers as though unsure what to do with it. She set it down with theatrical precision, then fixed Kiki with an intense stare.
“Delicious,” she said, smirk twitching. “But the true feast, Kiki Pizza… will be our experiment.”
Kiki tilted her head, one brow arched, though her lips still carried that indulgent smile. “Experiment?”
Jenny leaned on the counter, already grinning wide. “Oh yeah, you should hear this. Peri here doesn’t just do science — she does ‘pleasure trials.’”
Kiki’s cheeks colored, and she let out a startled laugh. “Wait—Jenny, are you serious?”
Peridot pushed her visor up her nose, utterly unbothered. “Correct. I test, I measure, I collect data on every variable. Reactions, sounds, physical responses. It is very rigorous.”
Kiki sputtered, covering her mouth as she laughed harder. “Oh my god, Jenny, you brought a total maniac into our shop!”
Jenny winked at her twin. “Yeah, but she’s kinda hot in her own weird little gremlin way, isn’t she?”
“Jenny!” Kiki swatted her sister’s arm again, laughing with embarrassment.
Peridot leaned forward over the counter, nails tapping against the laminate as her grin sharpened. “Imagine it, Kiki Pizza… you, under the microscope. Your every reaction catalogued. Your every nerve tested. All in the name of science.”
Kiki’s face flushed deeper, and she shoved the napkin dispenser at Peridot as a deflection. “You’re insane. I don’t know whether to laugh or call the cops.”
Jenny leaned closer, lowering her voice just enough for it to feel conspiratorial. “Don’t listen to her, Kiks. I’ve… seen what she can do. Trust me, it’s not as crazy as it sounds. And if you’re as stressed out as usual? Might actually do you some good.”
Kiki froze, caught between her sister’s teasing tone and Peridot’s manic, unblinking confidence. She shook her head, laughing nervously, hands flying to her hips. “You two are too much. I can’t believe you’re actually saying this stuff out loud.”
Peridot cackled, clapping her hands together. “Embarrassment detected! That means my experiment is already working.”
Jenny chuckled, bumping Kiki’s shoulder affectionately. “Don’t worry, sis. She doesn’t bite… unless you ask her to.”
Kiki groaned, covering her face with both hands, though she was laughing hard now, her voice muffled. “You’re both unbelievable.”
Peridot’s grin widened to a feral slash, her visor flashing in the fluorescent light. She planted both hands on the counter and leaned in close, her voice dropping to a purr.
“Think about it, Kiki Pizza. Your body under my command, every sigh and squirm measured. I’ll find out how long it takes before you break… and then I’ll make you beg me to do it again.”
Kiki’s jaw dropped. Her cheeks went scarlet as she gawked at the little gremlin practically crawling across the countertop toward her. “Y—you can’t just say stuff like that in the middle of the restaurant!”
Jenny laughed so hard she nearly spilled her soda, leaning against the counter for balance. “Oh, she can. She lives to say shit like that.” She reached over and flicked her twin’s hair, smirking. “C’mon, sis, you’re blushing like crazy. Don’t tell me you’re not at least a little curious what she’s packing in that lab of hers.”
“Jenny!” Kiki slapped her sister’s hand away, laughing nervously but unable to hide the grin spreading over her own lips. “You’re the worst!”
Peridot cackled, hopping up onto the counter stool and perching on her knees so she was nearly level with Kiki’s face. “She’s not wrong. You are curious. It’s written all over you. Your pulse elevated, your pupils dilated—don’t think I’m not recording this data.”
Kiki covered her face with both hands, groaning. “Oh my god, I cannot believe this is happening. You’re insane. Both of you.”
Jenny leaned in close, smirking ear to ear. “Bet you’re thinking about it now, though. All those long runs you do, trying to burn off stress? Bet it hasn’t crossed your mind how good it’d feel to burn it off with her tongue instead.”
Kiki gasped, her eyes snapping wide, her hands flying to smack Jenny’s shoulder. “Jenny! That is—!”
Peridot clapped her hands together like cymbals, eyes gleaming. “YES. Perfect suggestion. Oral calibration is always the ideal first test.” She hopped off the stool and strutted behind the counter like she owned the place, circling Kiki with a predatory little bounce in her boots. “Imagine it, Kiki Pizza. Your knees weak, your voice cracking, while your twin watches me dismantle you, piece by piece, until you’re begging to be my subject.”
Kiki’s legs pressed tight together, her cheeks blazing as she sputtered. “You—y-you’re both out of your minds! I’m not—I mean, I don’t—”
Jenny slid an arm over her sister’s shoulders, grinning like the devil. “Oh, you do, Kiks. You’re just too uptight to admit it.”
Peridot leaned in from the other side, her grin a razor curve. “That’s why I’m here. To make you admit it.”
Kiki looked between the two of them, trapped between Jenny’s playful pressure and Peridot’s relentless intensity. Her laughter turned nervous, ragged, and a little too breathless. “You’re both gonna kill me.”
Jenny just smirked and squeezed her shoulder. “Nah. We’re just gonna make you feel things you didn’t even know you wanted.”
Kiki doubled over the counter, laughing so hard her hair bobbed. “Oh my god, you two are killing me. You seriously cannot just roll into my work, spout… whatever that was, and expect me to swoon.” She wiped at her eyes, cheeks blazing as she tried to collect herself. “You’re ridiculous.”
Peridot folded her arms, nose in the air, and stomped one little boot. “Incorrect! I am irresistible! And soon, you’ll prove it.”
Kiki wheezed, clutching her stomach as she laughed again. “You sound like a cartoon supervillain.”
Jenny drained the last of her soda and set the cup down with a thunk, smirking. “Told you she was fun, didn’t I?” She leaned across the counter, voice dropping low, conspiratorial. “And come on, Kiks… you’re curious.”
“I am not!” Kiki insisted, too quickly, too brightly. “I’m working, Jenny. I’ve got orders, and the sign’s still on, and—”
Jenny reached over her shoulder, flicked the switch on the door. With a soft click, the neon OPEN sign went dark.
Kiki blinked. “…Jenny. What did you just—”
Jenny swung the lock on the door with her free hand, then leaned lazily against the counter, her grin wicked. “Turned the shop off. Nobody’s coming in. Nobody’s interrupting. It’s just us now.”
Peridot cackled, hopping back onto the stool beside Kiki and leaning close enough that her crooked visor almost touched Kiki’s cheek. “Perfect! Privacy achieved. The stage is set for experimentation.”
Kiki’s laugh turned nervous, shaky, though her smile never faded. “Y-you’re both crazy. Seriously, this is insane.”
Jenny looped an arm around her twin’s waist, tugging her close. “Relax, sis. Nobody’s making you do anything. But you’ve been running yourself ragged all summer, stressing over everything. Don’t you think you deserve a little… release?”
Kiki’s lips parted, the words caught in her throat. Her gaze darted between Jenny’s teasing smirk and Peridot’s manic grin.
Peridot tapped her stylus against her tablet, voice low and purring. “Think of it as… a break. A study break. A stress break. Let me collect my data while you forget all your worries. All you have to do is… say yes.”
Kiki’s laugh cracked into something more like a whimper, her cheeks hot as she pressed her hands over her face. “Oh my god, I cannot believe you’re both doing this to me right now.”
Jenny kissed her cheek, quick and playful, smirk still curling. “That’s not a no.”
Peridot’s grin stretched sharper. “No, it’s not.”
The shop was quiet now, the fryer’s hum the only sound under the fluorescent buzz. The locked door loomed behind them, the CLOSED sign glowing faintly. Kiki sat frozen at the counter, her apron wrinkled in Jenny’s grip, her face hidden behind her hands.
Jenny tugged one of those hands down just enough to see her twin’s flushed cheeks. “Look at you,” she teased, grinning wide. “You can’t even keep a straight face. You’re crumbling already.”
Kiki groaned through her palms. “I’m not crumbling! I’m just—ugh, you two are impossible!”
Peridot perched on the counter stool beside her, knees tucked under her chin, smirk sharp as a blade. “Incorrect. We are very possible. In fact, probability of surrender is climbing rapidly.” She tapped her stylus against the tablet. Subject Kiki Pizza: cheeks crimson, pulse high, laughter masking arousal. Resistance weakening.
Jenny laughed and leaned in, her breath brushing Kiki’s ear. “See? Even science says you’re cracking.”
Kiki swatted blindly at her with one hand, still laughing despite herself. “You’re the worst sister ever.”
Jenny caught her wrist, holding it gently but firmly against the counter. “Nah. Best sister. I’m trying to help you relax.” Her smirk curled as she tilted her head toward Peridot. “And she’s trying to make you scream.”
Kiki’s breath hitched, her laugh catching on the edge of a moan she didn’t want to let out. She pulled her wrist free, crossing her arms defensively — though it looked more like she was holding herself together.
Peridot leaned forward, her visor slipping down her nose, her grin impossibly smug. “You’re imagining it, aren’t you? My hands mapping every inch of your skin, my tongue cataloguing your reactions…” She purred, low and deliberate. “…your sister watching as you fall apart.”
Kiki made a strangled sound, half laugh, half gasp. “You can’t just say that—”
Jenny laughed, eyes sparkling with mischief. “Oh, she can. And the best part? You’re picturing it. I can see it on your face, Kiks.”
Kiki buried her face in her hands again, her shoulders shaking with nervous laughter. “I hate you. Both of you. This is so messed up.”
Peridot’s little boots hit the floor as she hopped down, padding closer. She leaned her elbows on the counter, chin propped on her palms, staring up at Kiki with that manic glee. “Messed up? No. This is perfect. A test subject with strong resolve, already crumbling under joint pressure. You’ll be magnificent data.”
Jenny slid behind Kiki now, looping her arms around her waist and resting her chin on her shoulder. “Don’t fight it, sis. You always take care of everybody else. Let us take care of you for once.”
Kiki shivered, trapped between the two of them, laughter thinning into nervous little breaths. “…You’re not gonna let this go, are you?”
Peridot cackled, her smirk wide and knowing. “Correct.”
Jenny’s lips brushed Kiki’s ear, whispering low. “So why not stop pretending and just give in?”
Kiki’s arms stayed crossed tightly over her chest, but she didn’t move when Jenny’s arms cinched a little closer around her waist, pulling her flush against her sister’s frame. Jenny’s lips brushed her ear again, the whisper deliberately low. “See? You’re not pushing me off.”
Kiki laughed nervously, voice shaky. “I—ugh, Jenny, you’re unbelievable.”
“Yeah,” Jenny said, grinning against her cheek. “But you’re not saying no.”
Peridot hopped up onto the counter in front of them, crouching on her knees with feline balance. Her crooked visor slid halfway down her nose as she studied Kiki with gleeful intensity. She leaned in, her hand lightly brushing Kiki’s wrist — not pulling, not prying, just touching.
Kiki stiffened… but didn’t yank her hand away.
Peridot smirked, stylus already scratching across the tablet screen. “Contact permitted. Resistance faltering. Data confirmed.”
“Stop calling it data!” Kiki groaned, but her voice cracked into another laugh.
Jenny’s lips grazed her jawline, gentle, playful. “It’s not just data. It’s you, sis. You’re letting it happen.”
Peridot leaned closer until her face hovered just inches from Kiki’s. “Correct. You’re curious. You want to know what happens if you let us push a little further.” She tilted her head, a tiny grin twitching wider. “Admit it.”
Kiki’s lips parted, but no words came. Her hands, still folded over her chest, trembled faintly — and when Peridot’s fingertip brushed her chin, lifting it slightly, she didn’t resist.
Jenny chuckled low, her arms tightening around Kiki’s waist. “She doesn’t have to admit it. Look at her. She’s letting you.”
Peridot purred, brushing her thumb against the corner of Kiki’s mouth. “Mouth slack. Pulse racing. And yet no retreat.” Her grin sharpened. “You’re breaking beautifully already.”
Then she leaned forward and pressed a quick, smug kiss to Kiki’s cheek.
Kiki gasped, half laugh, half stunned noise. “Peri—!”
Jenny laughed, kissing her on the other cheek. “See? Feels good, doesn’t it?”
Kiki trembled between them, her nervous laughter breaking into small, breathless sounds that weren’t quite moans but came dangerously close. She still hadn’t said yes. But she hadn’t stopped them either.
And that, to Peridot, was all the proof she needed.
“Phase two initiated,” she purred, curling closer, claws ghosting up Kiki’s arm. “Subject is compliant, even without verbal confirmation.”
Jenny smirked against her twin’s skin, murmuring into her ear. “Told you. You’re already ours.”
Kiki shivered, but this time she didn’t argue.
Jenny nuzzled along Kiki’s cheek, her lips brushing just under her ear before trailing lower, warm breath ghosting along her throat. Her hands slid up beneath the apron, palms flat against her sister’s stomach, kneading softly but deliberately as if testing just how far she could press.
Kiki gasped, her laughter breaking ragged. “Jenny—oh my god—you can’t—We’re sisters!”
“Sure I can,” Jenny murmured, teeth grazing the edge of her neck. “And you’re not stopping me, twin.”
Peridot crouched on the counter like a bird of prey, stylus tapping against her chin as her grin curved sharper. Her fingers traced lightly along Kiki’s wrist again, hovering, teasing. “She’s correct. You are allowing this. Compliance without protest. Subject’s temperature rising.” She tilted her head, peering at Kiki’s flushed face. “You’re squirming, but not from resistance. You like this.”
“I—n-no, that’s—” Kiki stammered, but Jenny’s lips pressed harder to her throat, sucking just enough to leave heat blooming there.
Peridot smirked. “Stammering detected. Another indicator of arousal.”
Kiki groaned, burying her face in her hands again. “You’re so embarrassing!”
Jenny chuckled against her neck, letting one hand drift higher, brushing the underside of her chest through the apron fabric. “She’s embarrassing, yeah. But she’s not wrong.”
Kiki’s breath caught, her whole body jerking at the touch, and Jenny smiled knowingly against her skin.
Peridot leaned closer, touch brushing up Kiki’s arm, her voice low and merciless. “Your body is betraying you, Kiki Pizza. Every tremble, every gasp. You can laugh, you can cover your face, but your body knows the truth. You want me to break you.”
Kiki whimpered softly behind her hands, her laughter turned thin and desperate. “Oh my god, stop saying stuff like that—”
Jenny’s teeth grazed her collarbone now, her hand kneading more boldly. “Why? Because she’s right? Because you can’t hide it anymore?”
Peridot purred, her crooked grin gleaming. “Admit it. Say it. Or don’t. Either way, your body will keep confessing for you.”
Kiki shivered violently, her laughter collapsing into shaky little breaths as Jenny’s hand teased higher and Peridot’s words struck sharper. She hadn’t said yes — but her silence, her stillness, her trembling, gave them all the proof they needed.
Jenny smirked, kissing her neck harder. “You’re ours, Kiks. You just don’t want to admit it yet.”
Peridot’s tablet beeped as she scrawled another note, eyes glinting with manic delight. “Exactly. Phase three: verbal denial, physical acceptance. Subject Kiki Pizza is beautifully conflicted.”
Jenny’s hand slipped just beneath the hem of Kiki’s apron now, teasing the waistband of her shorts with slow, deliberate circles. Her lips trailed back up her throat, stopping just shy of her jaw. “You’re trembling, sis. If you really didn’t want this, you’d have shoved me off by now.”
Kiki groaned, burying her face in her hands again. Her voice came muffled, shaky, and edged with laughter she couldn’t stop. “Ugh, fine, whatever! Maybe I like it, okay? Happy now?!”
Peridot’s grin sharpened like a scalpel, her stylus hovering midair as though she’d just struck gold. “Admission detected!” She scribbled furiously on her tablet. Subject confesses attraction verbally, albeit begrudgingly. Defensive humor employed. True acceptance imminent.
Jenny chuckled against Kiki’s skin, her smirk curving wider. “Oh, she’s so happy. But not as happy as you’re about to be.” She tugged the apron strings loose in one practiced yank, letting the fabric fall open across her lap.
“Jenny!” Kiki gasped, clutching at it, though weakly, without force.
Jenny kissed her jaw, whispering against her cheek. “C’mon, don’t be shy. You said it yourself.”
Peridot leaned forward from her perch on the counter, fingers tracing the exposed line of Kiki’s collarbone where Jenny had left red heat blooming. “Look at you. Red, hot, trembling. Trying to cover yourself while your body begs us to uncover more. Every part of you is data waiting to be recorded.”
Kiki groaned, half laugh, half whine. “You’re both the worst.”
Jenny smirked, slipping the apron down off her shoulders with a slow drag. “Nah. We’re the best. And you’re about to thank us for it.”
Kiki’s arms wrapped tight over her chest again as the apron sagged down into her lap. Her laughter cracked, breathy and panicked, but she didn’t stop them.
Peridot leaned closer, her grin feral, her voice soft and purring. “You can cover yourself if you want. It won’t change anything. I’ll still strip you down, one layer at a time. I’ll still map every inch of you. And your sister will watch the whole thing.”
Kiki whimpered, cheeks blazing as Jenny’s fingers teased the edge of her shirt hem now.
Jenny kissed her temple, voice low, playful, and hot in her ear. “Face it, Kiks. You’ve already lost.”
Peridot tapped her stylus against her tablet, smirk gleaming. “Correct. Subject Kiki Pizza has entered phase four: submission under teasing escalation.”
Kiki shook her head, laughing desperately through her groan. “Oh my god, you two are seriously gonna kill me.”
Jenny grinned against her skin, tugging at the hem of her shirt. “Nah. We’re just gonna make you melt.”
Kiki squirmed on the stool, arms locked stubbornly across her chest, laughter still bubbling ragged through her teeth. “You’re both insane, I swear—”
Jenny hooked her fingers under the hem of Kiki’s shirt and tugged. “Lift,” she ordered, smirking.
“No way!” Kiki clamped her arms tighter, though her flush betrayed her.
Jenny leaned in, lips brushing her ear again. “You already admitted it. Don’t make me peel you like an orange.”
Kiki’s laugh cracked into a squeal as Jenny slipped nimble fingers up her sides, tickling and prying all at once. Her arms flew up in reflex, and Jenny pounced, yanking the shirt over her head in one smooth motion.
“Jenny!” Kiki shrieked, half laughing, half scandalized, her hair mussed as she flailed uselessly.
“No bra, sis?” Jenny teased. “And at work, too, you little slut.”
Peridot clapped gleefully from her perch on the counter, crooked visor slipping further down her nose. “Yes! Excellent! Defensive reflex overridden. Garment removed. Subject Kiki Pizza now at forty percent exposure!”
“Stop keeping score!” Kiki groaned, wrapping her arms back across her chest, cheeks flaming.
Jenny chuckled low, balling up the shirt and tossing it onto the counter. “You’re adorable when you’re flustered, Kiks. But hiding won’t help. I’ll just keep going.”
Peridot hopped closer, crouching in front of Kiki now, hands ghosting down her bare side. “Look at you. Gooseflesh everywhere. Your body reacts faster than your mouth can deny. Fascinating.” Her grin curved sharper. “Do you want me to document every twitch as we strip you completely?”
Kiki whined, laughing nervously as Jenny’s hands slipped lower, teasing the button of her shorts. “Oh my god, you’re the worst.”
Jenny kissed the slope of her shoulder, one hand working the button free with a deft twist. “Nah. The worst would be leaving you dressed. And we’re definitely not doing that.”
Kiki gasped as the zipper came down, her breath hitching hard, but she didn’t stop her. She just covered her face again, groaning into her hands. “This is so wrong…”
Peridot purred, fingers brushing the waistband as Jenny tugged the shorts down her hips. “Wrong? Incorrect. This is science. This is progress. This is you, unraveling piece by piece, exactly as predicted.”
Jenny smirked as she peeled the shorts past Kiki’s thighs, tossing them aside with her shirt. “And now you’re sitting here in your underwear with both of us all over you. Not so wrong now, huh?”
Kiki trembled, her bare legs pressed tight together, laughter thinned to shaky breaths. “…You’re both unbelievable.”
Peridot leaned up, grinning sharp against her ear. “And you’re nearly naked. Which means you’ve already lost.”
Jenny’s hands were already sliding up Kiki’s thighs, nails scratching lightly along her skin, while Peridot prowled in close from the other side, crouched like a predator. The twin pressure made Kiki squeal, her legs squeezing together. “Oh my god, stop—this is insane!”
Jenny smirked, fingers hooking the waistband of her panties. “Not stopping, sis. You know that by now.” With a teasing tug, she began to draw them down.
Kiki gasped, hands flying to cover herself, but Peridot was quicker. Her fingers caught Kiki’s wrists, tugging them down just far enough for the fabric to slide free. “Garment removed!” Peridot crowed gleefully, holding the panties up like a trophy before tossing them aside. “Subject fully exposed! Victory!”
“Peri!” Kiki whined, her voice cracking between laughter and outrage, cheeks a furnace.
Jenny leaned back just enough to admire her. “Damn. Didn’t think I’d get to see you like this again. You’re gorgeous, Kiks.” Her smirk curved. “And I’m not the only one who thinks so.”
Peridot’s crooked visor slid halfway off her nose as her eyes roved hungrily. She licked her lips, hands ghosting along Kiki’s bare hip. “Magnificent. So much to test, so much to taste. Where to begin?”
Kiki squeaked, her hands fluttering uselessly over her own body like she couldn’t decide what to cover first. “This is so wrong, you’re both crazy!”
Jenny kissed her cheek, sliding a hand boldly over her chest, squeezing gently. “Maybe. But your body doesn’t care, does it? You’re burning up.”
Peridot purred, circling behind Kiki now, nails dragging down her spine in delicate scratches that made her arch with a shudder. “Correct. She’s trembling everywhere. Her skin sings under my claws.” She leaned close, lips grazing Kiki’s ear. “You like this.”
Kiki whimpered, half laugh, half moan, her thighs parting instinctively under Jenny’s teasing hand. “Oh my god, I—shut up—”
Jenny’s smirk widened as she pressed her lips to Kiki’s throat again. “Don’t tell her to shut up, sis. You love it when she talks dirty.”
Peridot cackled softly, circling around to crouch between Kiki’s knees, hand resting possessively on her thighs. Her grin gleamed up at her. “Your body’s mine to explore now. And Jenny’s. Every twitch, every sound, every taste. We’ll map you until you’re begging us not to stop.”
Kiki’s laughter broke into a sharp, startled moan as Jenny’s fingers finally slipped lower, teasing lightly, while Peridot’s tongue darted out to trace a burning path along her thigh.
“Data confirmed,” Peridot murmured smugly against her skin. “She’s already melting.”
Jenny cupped Kiki’s jaw with one hand, turning her face just enough to claim her mouth in a rough, hungry kiss. Kiki squealed against her lips, hands caught awkwardly between pushing and clutching, but the sound melted quickly into a muffled whimper as Jenny pressed harder, tongue slipping in to taste her.
Peridot smirked at the sight before turning her focus lower. She spread Kiki’s trembling thighs with sharp little nudges, crouched close enough that her crooked visor almost slid off her nose. “Specimen fully available,” she purred, voice vibrating with anticipation. “Perfect.”
Kiki gasped into Jenny’s mouth when she felt Peridot’s tongue, hot and wet against her folds. Her whole body jerked, one leg kicking out against the counter as if to escape — but Jenny held her firm, kissing her deeper, swallowing every sound.
Peridot groaned low, her tongue lapping with greedy, experimental strokes. She alternated pressure, angles, speed, cataloguing every twitch and gasp. She pulled back just long enough to scribble a note on her tablet, her grin manic. “Subject Kiki Pizza: extreme sensitivity noted. Response immediate.” Then she dove back in, lips sealing around her clit with a sharp suck.
Kiki’s laugh broke into a high, panicked moan, her fingers tangling in Jenny’s shirt as she bucked helplessly. “Oh my god—Jenny—Peri—I can’t—”
Jenny caught her lips again, silencing her with another kiss, one hand sliding boldly over her chest now, kneading her breasts. “You can, sis. You’re doing amazing. And you’re gonna do even better.”
Peridot hummed against her, claws digging gently into her thighs to hold her open while her tongue traced ruthless patterns. Every tremor, every shiver, every tightening of Kiki’s body fed her glee. She pulled back just enough to taunt, her mouth slick, her grin wicked. “Your body sings for me. You can’t stop it. You don’t want to stop it.”
Kiki moaned again, louder this time, head tipping back against Jenny’s shoulder, her laughter gone, replaced by ragged gasps.
Jenny smirked, lips grazing her ear between squeezes at her chest. “See? I told you. You’re ours now, Kiks.”
Peridot’s tongue pushed deeper, relentless, cataloguing every twitch with manic delight. She muttered between licks, half to herself, half to taunt. “Perfect reactions. Impeccable responsiveness. I could devour you forever.”
Kiki’s fingers clutched at Jenny’s arms now, her thighs trembling violently around Peridot’s head. “I—I can’t—”
Jenny grinned, kissing her temple. “Oh, you definitely can. And you’re gonna.”
Kiki’s thighs clamped desperately around Peridot’s head, her whole body jerking as the waves built. Jenny smirked, feeling her twin’s nails dig into her arms, her chest heaving against her hand.
Peridot hummed, tongue pressing harder, faster, until Kiki’s voice pitched high with a frantic, “I—I—oh god—!”
And then—she stopped.
Peridot pulled back slick-lipped, still gripping Kiki’s thighs to hold her wide open, her grin viciously smug. “No.”
Kiki’s body convulsed with the aborted release, her voice breaking into a whine. “Peri—what the hell—!”
Jenny chuckled darkly against her ear, kissing her sweaty temple. “She’s not gonna give it to you easy, sis.”
Peridot licked her lips, scribbling a furious line of notes on her tablet with her other hand. “Subject Kiki Pizza: climax interrupted. Frustration immediate. Perfect. Now… verbal confirmation required.” She leaned up, visor flashing as her grin widened. “Say it. Tell me you want more. Beg me to finish you.”
Kiki groaned, face buried in her hands, shaking her head furiously. “No way—I’m not—ugh—you’re both insane!”
Jenny squeezed her breast harder, pinching a nipple teasingly as her lips brushed her ear. “Come on, Kiks. You’ve been playing coy this whole time. But your body’s not lying. You need it.”
Kiki whimpered, thighs trembling against Peridot’s grip, every nerve screaming for the release she’d been denied. “Oh my god—this is torture—”
Peridot cackled, leaning close, her voice cruel and gleeful. “Correct! Torture by denial. But easily solved. All you have to do… is beg.”
Kiki shivered violently, her nervous laughter cracking into ragged little gasps. “…You’re the worst.”
Jenny kissed the corner of her mouth, murmuring hot against her lips. “And you love it. Say it, sis. Tell her you need it.”
Peridot pressed one finger lightly against her slick folds, teasing but not pressing. “Say it, Kiki Pizza. Admit it. Or I’ll deny you again and again until you’re screaming it.”
Kiki’s hands clutched uselessly at Jenny’s arms, her body trembling on the stool. She whimpered, breath catching on a laugh that sounded more like a sob. “…Fine! I—I need it! I need you! Okay?! Happy now?!”
Peridot’s grin went feral, sharp and triumphant. “Ecstatic.”
Jenny kissed her deeply, tongue sliding into her mouth as she smirked against her lips. “There’s my good girl.”
Peridot crouched back down, claws anchoring Kiki’s trembling thighs. “Confession accepted. Now I’ll give you what you’ve been dying for.”
Peridot dove back in without hesitation, tongue flat and relentless against Kiki’s soaked folds. This time she didn’t tease, didn’t play coy. She devoured.
Kiki’s voice broke into a sharp, ragged moan, her whole body jerking forward against Jenny’s chest. Jenny tightened her grip, one hand clamping firmly over her breast, the other wrapping around her waist to pin her in place. “That’s it, sis. Let her ruin you.”
Peridot hummed, tongue tracing ruthless patterns, lips sealing over her clit to suck hard. Her fingers dug into Kiki’s trembling thighs, holding her open for every frantic stroke.
Kiki gasped, squealed, then cried out helplessly, her laughter gone, replaced by desperate, high-pitched moans. “I—I can’t—oh my god, I can’t—”
Jenny kissed her cheek, smirking against her sweat-flushed skin. “Yes, you can. She’s making sure of it.”
And then Kiki shattered, her thighs clamping tight around Peridot’s head, her body shaking with release as her voice broke loud and raw into the empty restaurant. Jenny held her through every spasm, kissing her jaw, whispering soft teases: “Good girl… knew you’d give in…”
Peridot pulled back at last, her mouth slick, her visor askew. She wiped her lips with the back of her hand, grinning sharp and triumphant. “Data confirmed. Subject Kiki Pizza: utterly broken by oral calibration. Perfect.”
Kiki slumped against Jenny, limp and panting, her cheeks still blazing. “You’re both… oh my god… I can’t believe you actually—”
Peridot tapped her tablet, then set it aside. Her claw slipped into her belt pouch, producing a small, gleaming band of tech — the human collar. She held it up between two fingers, letting the light catch on its edges.
“Phase two,” she purred. “Collar integration.”
Kiki blinked at it blearily, her chest still heaving. “Collar? What is—”
Peridot’s grin widened. “A device of my own design. Invisible to others, but always felt by you. It amplifies your pleasure, ensures your loyalty, and… when I call, you’ll come. Always.” She leaned closer, the band glinting between her fingers. “This is what it means to belong to me.”
Kiki flushed deeper, her lips trembling as her body still quivered from the aftershocks. “…That’s insane.”
Jenny nuzzled her cheek, whispering warmly. “But you want it.”
Kiki shivered, her breath hitching as she turned her face into Jenny’s neck, not daring to deny it.
Peridot smirked, slipping the collar into Jenny’s waiting hand. “Then you’ll put it on her. Just before her next climax. Seal her fate yourself.”
Jenny’s grin spread slow and wicked as she closed her fingers around the device. “With pleasure.”
Peridot rose smoothly from between Kiki’s thighs, her grin feral. She reached into her satchel and drew out one of her newest inventions — a sleek, curved synthetic phallus with glimmering panels and a strap apparatus that clicked into place around her narrow hips. The faint glow of its internal mechanisms pulsed like a heartbeat.
Kiki’s eyes widened, her breath catching. “W-wait, what is—”
Peridot tightened the straps with a sharp tug, the device settling snug against her. “Phase two,” she purred, voice dripping with smugness. “Full-body calibration. Amplification of response. Collar integration.”
Jenny’s smirk went sharp and wicked as she held the collar up in one hand, thumb brushing the trigger mechanism. “This is gonna blow your mind, sis.”
Peridot stepped forward, claws gliding up Kiki’s trembling thighs again as she pressed the tip of the device against her slick entrance, not pushing yet, just teasing. “Feel how it vibrates even before penetration. This is what true innovation tastes like.”
Kiki gasped, her hands fluttering uselessly at her sides. “This is—oh my god—”
Peridot leaned in, lips close to her ear, voice soft and cruel. “You’re mine now, Kiki Pizza. Say it.”
Kiki whimpered, looking up at Jenny for help, but Jenny only smirked and tilted the collar in her hand. “Say it, Kiks. Or I’ll wait even longer to give you this.”
Peridot rolled her hips just enough for the tip to slip inside, the vibration humming low and deep. “Say it.”
Kiki moaned raggedly, her body arching despite herself. “…I’m—yours. Okay? I’m yours.”
“Good girl,” Peridot purred, driving the device in with a slow, deliberate push.
Kiki’s head tipped back against Jenny’s shoulder, a strangled sound tearing from her throat as the vibrations filled her pussy. Jenny’s free hand began kneading her breast hard, teasing the nipple until it stiffened under her palm. “She’s so wet already,” Jenny murmured, low and dirty. “You’ve got her perfect, Peri.”
Peridot started to thrust, small precise movements at first, then deeper, harder, the vibrations syncing with each motion. Her hands gripped Kiki’s hips, holding her steady as she murmured between thrusts: “Perfect response. Temperature rising. Pulse accelerating. Ready for integration.”
Kiki moaned helplessly, legs trembling, hands clutching at Jenny’s arms. “I—I—oh my god—”
Jenny leaned in, lips brushing her ear. “Shh. Almost there.” She pressed the collar against Kiki’s neck, not fastening it yet. “When you’re about to cum, sis, I’m gonna snap this on. And then you’ll never forget who you belong to.”
Peridot’s grin went vicious, her thrusts quickening, the glow of the device pulsing brighter. “Climax imminent. Prepare for integration.”
Kiki gasped, hips rolling back against the device without realizing it, her voice breaking into raw, desperate moans. “Please—please—oh my god—”
Jenny smirked, her thumb on the collar’s clasp. “Now, Peri?”
Peridot’s claws dug into Kiki’s hips, her voice a low hiss. “Now.”
Jenny snapped the collar shut with a click just as Peridot slammed the device deep, the vibrations spiking. The collar’s hidden circuits lit once, then vanished into invisibility — but Kiki felt it, a jolt of warmth and pleasure flooding through her at the same instant the device sent her over the edge.
She screamed, her whole body convulsing between them, every nerve lighting up as the collar sealed her fate.
Peridot held her through it, thrusting slow and deep as she trembled, grinning sharp as she watched the transformation take hold. “Integration complete. Subject Kiki Pizza: perfect.”
Jenny kissed her cheek, murmuring hotly. “Told you, sis. You’re ours now.”
Kiki sagged against her, limp and panting, a dazed little smile creeping over her flushed face despite herself.
Kiki slumped forward against Jenny, trembling, her breath coming in ragged gasps. The collar’s invisible circuits still pulsed faintly under her skin, a warm hum radiating through her neck and down her spine. Her thighs quivered around Peridot’s hips, small aftershocks running through her body even as the synthetic phallus stayed buried deep.
Jenny loosened her hold and eased Kiki back into her lap, cradling her as she stroked slow, soothing circles over her slick skin. “There you go, Kiks,” she whispered, her voice low and warm now instead of teasing. “Breathe. You did so good.”
Kiki whimpered softly, head falling back against her sister’s shoulder, eyes dazed but glassy with relief. “Oh my god…” she breathed. “I… can’t even…”
Peridot’s grin stayed sharp but her voice softened slightly as she disengaged the device, the faint hum shutting off. She set the phallus aside on the counter, then immediately snatched up her tablet, stylus scratching furiously across the screen. “Integration successful. Subject’s responsiveness exceeded projections. Post-release relaxation evident. Collar bond stable.”
Jenny kissed Kiki’s temple, hugging her a little tighter. “She talks like a robot but trust me, that’s her way of saying you were amazing.”
Kiki let out a weak laugh, her flushed face tilting toward Peridot. “…You’re insane.”
Peridot’s crooked visor glinted as she looked up from her tablet. “Incorrect. I’m brilliant. And you…” She tilted her head, smirk twitching. “You’re an excellent subject.”
Jenny chuckled, brushing damp hair from Kiki’s face. “She means ‘good girl.’”
Kiki gave a tiny, embarrassed laugh, curling instinctively into Jenny’s chest as the warmth from the collar lingered, making her feel oddly safe despite everything. “I… can feel it,” she murmured. “Like it’s still humming.”
Peridot scribbled another note, muttering under her breath. “Perfect. Baseline sensation persists post-application. Reinforcement achieved.” She crouched closer, fingers ghosting lightly over Kiki’s thigh — not sexual this time, just tracing, mapping. “You’ll always feel it. Even invisible, it’s there. A reminder.”
Jenny kissed her cheek, still holding her gently. “It’s a good thing. Means she’s got you. Means you’ve got her. And you’re not alone.”
Kiki blinked up at them both, still blushing but too exhausted to hide the small, soft smile creeping across her face. “…You’re both unbelievable.”
Peridot smirked, jotting her last note. “And you’re mine.”
Jenny squeezed her gently, whispering again. “Rest now, Kiks. You earned it.”
Kiki sagged fully into Jenny’s lap, the collar’s warmth a strange comfort as she let herself drift.
The air in the restaurant was thick now, a faint scent of salt and sweat clinging to the counters. The CLOSED sign still glowed faintly in the window, neon humming over the quiet as Kiki sat, spent and dazed, leaning against Jenny’s chest.
Peridot set her tablet aside with a little clack and clapped her hands together. “Phase three: comparative analysis.” Her visor glinted as she looked up at Jenny. “Strip.”
Jenny arched a brow, but her grin curled slow and knowing. “Always straight to business, huh?” She eased Kiki upright gently, brushing her thumb along her cheek. “You okay, Kiks?”
Kiki blinked up at her, still flushed, still humming from the collar, and gave a small, breathless laugh. “…I don’t even know anymore.”
“Good enough,” Jenny murmured, then stood, peeling her jacket off her shoulders. One by one she stripped off her layers, her smirk never fading as she let the fabric pool at her feet until she was as bare as her sister.
Peridot’s grin stretched sharp and satisfied, her hands flexing as she looked them over. “Magnificent. Twin human specimens, one freshly collared, one cooperative. Perfect conditions for comparison trials.”
Jenny hopped up onto the wide stainless-steel prep counter, knees apart, her palms flat against the cool surface as she posed with a cocky tilt of her head. “You’re the boss, Peri.”
Kiki hesitated, cheeks burning. “This is so—”
Jenny reached down, tugged her gently up beside her. “Come on, Kiks. You’ve already come this far. Might as well see what she does next.”
Kiki groaned but let herself be guided, crawling onto the counter on her hands and knees beside her sister. The two of them lined up, mirror images with only slight differences — Kiki’s softer tone, Jenny’s sharper angles — both of them flushed and glistening under the kitchen lights.
Peridot purred low in her throat, circling them like a predator admiring her catch. “Perfect symmetry. Observable variations. So much data…” She crouched behind them, hands resting lightly on each of their ankles. “We begin with feet and legs. Prepare yourselves.”
Jenny chuckled. “Always wanted a pedicure, but I guess a Peridot-cure will do.”
Kiki laughed nervously, glancing over her shoulder. “You’re insane.”
Peridot leaned down and dragged her tongue slowly across Jenny’s arch, a firm, deliberate lick from heel to toes. Jenny shivered, toes curling, her smirk faltering into a soft gasp.
Then Peridot did the same to Kiki, tongue tracing the identical arch of her foot, her fingers massaging gently up her calf as she went. Kiki squealed softly, her knees shifting, the involuntary noise slipping past her lips.
“Comparison initiated,” Peridot murmured between licks, her grin crooked. “Jenny Pizza: callused pads from activity. Stronger tendon tension. Kiki Pizza: softer arches, higher sensitivity. More involuntary reaction.”
Jenny snorted, glancing back. “You’re literally narrating while you lick us?”
Peridot smirked up at her, licking between her toes. “Of course. This is science.”
She moved back and forth between them, her hands gliding higher now, tracing their calves, then the backs of their knees, tongue flicking between touches. Kiki trembled more visibly, biting her lip, while Jenny arched her back and let out a low hum of appreciation.
“Data confirmed,” Peridot purred. “Both subjects highly responsive to oral stimulation along lower limbs. Kiki more ticklish, Jenny more prone to arching.”
Kiki groaned, hiding her face against her folded arms. “Oh my god…”
Jenny chuckled, giving her twin’s hip a playful bump. “Relax, Kiks. She’s thorough, but it’s worth it.”
Peridot’s claws slid up their thighs now, kneading gently, her tongue flicking little circles against the sensitive spots where muscle met skin. “Identical musculature. Slight difference in tone. Both delectable.”
She paused just long enough to scribble a quick note on her tablet, then licked slowly up the inside of Jenny’s thigh, followed by Kiki’s, alternating between them as if tasting two vintages of the same wine.
Both twins shivered in unison, their hands gripping the edge of the counter.
Peridot’s grin widened. “Oh yes. This will be very satisfying.”
Peridot dragged her nails up the backs of both twins’ thighs, squeezing possessively as she rose onto her knees behind them. Her grin sharpened as her hands settled on the round curves of their asses, kneading with greedy delight.
“Phase two: gluteal comparison,” she purred, her voice thick with glee. “Jenny Pizza: firmer, more muscle definition. Kiki Pizza: softer, yielding, yet equally bountiful.” Her crooked visor slid down her nose as she leaned close, practically rubbing her face against their cheeks. “Both exceptional.”
Kiki squealed into her arms, her whole body trembling as she tried to hide her burning face. “Oh my god, I cannot believe this is happening—”
Jenny chuckled, arching her back to push into Peridot’s touch. “Believe it, sis. She’s having the time of her life back there.”
Peridot licked a slow, deliberate stripe across Jenny first, then immediately mirrored the motion on Kiki, her tongue tracing the curve of each cheek before darting down into the crease. She hummed loudly, her claws kneading harder as she lapped at them both in turn.
“Jenny: saltier taste, strong reaction to firm pressure. Kiki: sweeter, twitchier, involuntary gasps noted.” She punctuated the observation by smacking Jenny’s ass with a sharp slap, then doing the same to Kiki, watching both twins jolt under the impact.
Kiki yelped, her voice pitching high. “Peri! Oh my—”
Jenny moaned low, her smirk curling. “Mmm… she likes the rough stuff, Kiks. I told you.”
Peridot cackled, alternating sharp spanks between them, her hands gripping the reddening flesh immediately after each smack. “Data confirmed! Jenny: moans at impact, presses back into the strike. Kiki: squeals, clenches, tries to squirm away. Both exquisite.”
She leaned in again, tongue sliding lower this time, licking boldly between their cheeks, savoring the way each of them shivered differently. Jenny’s hums were low and throaty, while Kiki’s whimpers cracked between gasps and nervous laughter.
Peridot pulled back just enough to smirk at them both, her visor fogged slightly. “Comparison complete. Verdict: impossible to choose. Both subjects… delicious.”
Jenny chuckled, twisting just enough to glance at her twin, still flushed and trembling. “See, Kiks? She’s treating us like a buffet.”
Kiki groaned into her arms, but her hips still wiggled against the counter, betraying her. “…You’re both unbelievable.”
Peridot smirked, scribbling on her tablet with one hand while licking her lips clean. “Unbelievable results require unbelievable methods.” She set the tablet aside with a clack, hands settling possessively on both their hips. “Now… on to phase three: core analysis.”
Peridot squeezed both twins’ hips, her claws digging in as she dragged them apart just enough to admire the sight. “Time to catalog taste, tightness, responsiveness. Prepare yourselves.”
Jenny chuckled, smirking over her shoulder. “I’m ready.”
Kiki groaned into her arms, muffled and high-pitched. “Oh my god, this is humiliating—”
Peridot cackled, smacking her ass sharply enough to make her jolt. “Correct! That’s the point.” She pressed her mouth forward without hesitation, tongue flattening against Jenny’s pussy first, lapping a long stripe from her entrance up to her clit.
Jenny moaned low, pressing back against her, hips rolling deliberately into the touch. “Mmm… yeah, she wasn’t kidding. Damn, Kiks… this is wild.”
Peridot hummed into her, then pulled back abruptly to switch to Kiki, giving her sister the exact same treatment — a slow, greedy lick up her folds, tongue flicking the sensitive nub before pulling away.
Kiki gasped, her whole body jerking. “P-Peri—!”
Peridot’s grin spread slick and feral. “Comparison: Jenny’s flavor bolder, heavier, more forward. Kiki’s sweeter, subtler, delicate. Both exquisite vintages.” She smacked each ass again, alternating, then ground her sharp chin against their cheeks before diving back in.
Jenny’s moans deepened as Peridot sucked her clit, one green hand gripping her thigh to keep her steady. Kiki whimpered and squealed as Peridot switched again, tongue plunging deep inside her this time, curling and stroking ruthlessly.
The twins’ voices rose in a messy duet — Jenny low and throaty, Kiki high and breathless, their bodies rocking against the counter as Peridot alternated between them, cataloguing with every lick.
“Jenny: thrusts back aggressively, moans steady, responsive to suction.” Slap.
“Kiki: clenches involuntarily, squeals, trembles under penetration.” Slap.
Both jolted, both dripping for her.
Peridot smirked against Kiki’s folds, grinding her chin against her clit before pulling away again. “Verdict: impossible to choose a favorite. Both subjects prime material for extended trials.”
Jenny panted, smirking even as her cheeks flushed. “She’s insane, but she’s got a hell of a tongue.”
Kiki hid her face, squealing again as Peridot gave her one last greedy lick. “…I can’t believe I let you talk me into this.”
Jenny chuckled, kissing her shoulder as Peridot licked her lips clean behind them. “You don’t regret it though, do you?”
Kiki whimpered, her hips betraying her with a little twitch back toward Peridot’s touch. “…Shut up.”
Peridot cackled, scribbling notes on her tablet with one hand while her other squeezed both their asses. “Subjects responsive, humiliated, and primed for final phase.” Her grin curved sharp and hungry. “Sequential climax trials.”
Peridot’s hands snapped the clasps of her harness into place with crisp efficiency, the faint hum of her synthetic invention filling the closed shop. This model was sleeker, longer, its body forking into two vibrating shafts that glowed faintly in tandem — one for each subject.
Her grin spread viciously as she stood behind the twins, who were still kneeling on hands and knees across the counter, flushed and trembling from her tonguework. “Phase four: dual penetration analysis. Identical specimens side by side. Perfect.”
Kiki’s head shot up, eyes wide. “W-wait—two?!”
Jenny chuckled, glancing at her twin with a smirk. “Don’t fight it, Kiks. Might as well let her finish the set.”
Peridot cackled, guiding each glowing shaft with greedy precision, the tips teasing slick folds already dripping for her. “Correct. Resistance is futile. Prepare for calibration.”
Jenny groaned low as the device slid into her with ease, the vibration thrumming deep as Peridot drove it in slow and deliberate. “Ohhh, damn—yeah, that’s it…”
Kiki squealed as her side followed, the second shaft stretching her, humming against nerves already raw from her earlier climax. “Oh my god, Peri—I can’t—”
“You can,” Peridot hissed gleefully, slamming the straps tighter against her own hips. “You will. Both of you. At the same time.”
She began to thrust, hips snapping forward with measured rhythm that made the twin shafts pulse in unison. Jenny moaned deep, pressing back into it, while Kiki squeaked and whimpered, her thighs trembling as she tried and failed to hold steady.
Peridot gripped both their hips hard, her nails biting just shy of pain, her visor flashing as she looked down at her conquests. “Comparison in real time. Jenny: stable moans, steady rhythm. Kiki: inconsistent, higher pitch, trembles beautifully. Both subjects tightening already.”
Slap. She smacked Jenny’s ass. Jenny only moaned louder, arching harder.
Slap. She smacked Kiki’s next. Kiki yelped, gasping into the counter.
“Data confirmed,” Peridot crooned, her thrusts quickening, the vibrations spiking in tandem. “Jenny craves impact. Kiki squirms under humiliation. Both exquisite.”
Jenny reached across, fingers tangling in her twin’s hand, squeezing tight as they rocked together under Peridot’s relentless pace. “Almost there, Kiks—hold on with me…”
Peridot cackled, pounding harder now, sweat slicking her green skin as her fingers dug bruises into their hips. “Yes! Together! Simultaneous climax trial — optimal result!”
The twins’ voices rose in messy harmony, Jenny’s low and guttural, Kiki’s high and broken, both shaking as the device thrummed mercilessly inside them. Peridot leaned over their backs, gloating between growls. “Scream for me. Prove you’re mine. Show me you’re perfect data!”
Their cries peaked together, twin bodies convulsing in sync as the dual phallus vibrated harder, milking every spasm. Jenny’s moan broke into a hoarse laugh of satisfaction, while Kiki’s voice cracked into a desperate squeal that echoed off the kitchen walls.
Peridot held them pinned through every shudder, every twitch, thrusting deep until they finally slumped boneless across the counter, gasping wrecks.
The little gremlin straightened, slick and smug, tapping notes onto her tablet even as the shafts pulsed within the twins. “Result: flawless. Simultaneous climax achieved. Twin comparison complete.”
Jenny groaned, reaching back to pat Kiki’s hand again, grinning weakly. “Told you… worth it.”
Kiki whined into her arms, too dazed to argue, her collar humming faintly as if agreeing.
Peridot purred, licking her lips. “Perfect. Two more specimens secured.”
The counter gleamed with sweat and heat, the smell of salt and pizza dough hanging thick in the air. Jenny and Kiki lay collapsed side by side, chests heaving, their hands still linked loosely as aftershocks trembled through their bodies.
Peridot stood between them, strapping off her dual phallus with sharp clicks, setting the still-humming invention on the prep table with the reverence of a completed masterpiece. She dusted her hands smugly, visor slipping down her nose.
“Phase complete,” she declared, voice rich with triumph. “Two specimens, collared and catalogued. Victory absolute.”
Jenny chuckled hoarsely, rolling onto her side, her smirk lazy. “You’re a menace… but a good one.”
Kiki groaned into her arms, her voice muffled but shaky with reluctant laughter. “I can’t believe I let you—oh my god…”
Peridot clapped her hands together, hopping up onto the counter between them. She tugged off her little green boots, letting them clatter onto the tiles. “Excellent. Now for my reward.” She stretched out, planting her bare feet in front of their flushed faces, wiggling her small toes with imperious delight. “Worship me.”
Jenny grinned immediately, catching her sister’s hand to tug her closer. “You heard her, Kiks. Get in there.”
Kiki whined, cheeks blazing, but the collar’s hum nudged her compliance. Together, side by side, the twins leaned in, pressing lips and tongues to Peridot’s pale-green feet. Jenny licked boldly, teasing between toes, while Kiki kissed softly, shy and trembling.
Peridot leaned back on her palms, her grin splitting wide, visor sliding to the tip of her nose. “Perfect. The Pizza sisters at my feet, proving my brilliance. This… is triumph.” She groaned smugly as their mouths worked her soles, her toes flexing against their lips. “Yes… exquisite. Record this moment: absolute dominance.”
Jenny’s smirk only deepened as she licked higher up Peridot’s sole, while Kiki’s muffled whimpers against her toes betrayed her shame.
Peridot cackled, head tipping back. “You’re mine now. Both of you. Forever.”
The kitchen door creaked open.
“Eh? What is all this?”
The three of them froze.
Standing in the doorway, framed by the dim light of the back alley, was Nanefua Pizza herself — apron still tied, cane in one hand, eyes wide with sharp, startled clarity. Her gaze swept the room in a single second: her granddaughters naked on their knees, faces pressed to the green gremlin’s little feet, the air stinking of sweat and sex.
Jenny’s smirk faltered, Kiki squeaked into Peridot’s toes, and Peridot—barefoot, smug, unbothered—just grinned wider, her visor flashing as she whispered:
“…Phase five.”
