Author's Chapter Notes:

And a new chapter! 

Enjoy! Please let me know what you think :) 

The situation felt unreal. Moments ago, his sister had towered over him like an insurmountable mountain, her body a massive, all-encompassing presence. Now, though she had shrunken to a more manageable size, she was still double his height—her form far more familiar yet still undeniably overpowering. It was a cruel illusion of normalcy. She wasn’t the mountain anymore, but she was still the giant. Still the one in control.

But Levi couldn’t fight the urge to tackle her earlier. He had to try. After everything she’d done to him—with him—he couldn’t just sit there. Days spent suffocating in her fluids, pressed against her wet flesh, being reduced to something less than human. And digestion—God, he could still feel the phantom sensation of her stomach squeezing him like he was a piece of discarded food.

Yet here she was, smirking and giggling, treating it all like some naughty game between siblings.

When he had charged at her, he’d hoped—prayed—he could prove she wasn’t invincible. But now, as she straddled him with ease, pinning his struggling form to the floor, reality sank in. He was still helpless. Still her toy.

“Come on, bro,” Luna teased, her voice lilting and light, but with that infuriating undercurrent of amusement. She leaned forward, her hair falling in a curtain around them. “Are you done fighting me yet?”

“Get off me, Luna!” Levi snapped, his face flushed with rage and frustration. He twisted and kicked beneath her, but all it earned him was a laugh.

She easily caught his wrists, pinning them down beside his head as she leaned closer, her grin growing wider. “You know you’re not getting anywhere, right?” Her breath washed over him, warm and far too intimate. Her face, twice the size of his own, hovered above him like some mocking goddess.

He jerked his head to the side, refusing to meet her playful gaze, but she followed him easily, her eyes sparkling with delight at his resistance. “Not until we chat,” she said, her voice sweet but firm.

“No!” Levi yelled. “Just let me go!” His legs thrashed, bumping against her thighs, but the effort was laughable. Luna’s body barely shifted. She giggled again, shaking her head at his futile attempts.

“Levi,” she said softly, her tone dripping with condescension. “Stop embarrassing yourself.” She let him struggle a little longer, her grin widening as the reality of his powerlessness sank in.

“This must feel familiar,” she cooed, her voice dropping to a teasing whisper. “Like when we were kids, and you’d pin me down. Except now…” She shifted her weight, pressing down just enough to make him wince. “Now you’re the one who’s helpless.”

Levi clenched his jaw and turned his head away, refusing to look at her. He hated how much her words stung because they were true. He was the one at her mercy now. Slowly, his struggles ceased, his breath ragged as he glared up at her. “Please, Luna,” he said, his voice quieter this time. “Just… stop.”

Luna giggled, her playful grin softening, but only slightly. “All right,” she said lightly, leaning back as her weight shifted off him. “I’ll stop teasing…” She smirked. “For now.”

She sat up straighter, her knees resting on either side of him, pinning him in place. Her eyes scanned the tiny apartment, and her lips curled into an amused smile. “Wow,” she said, glancing around at the pink decor. “It’s so cute.” She clapped her hands against her knees, taking in every little detail. “It’s like a dollhouse—but better!”

Levi groaned, rolling to his side to get away from her, but her towering form still loomed over him, her playful energy filling the room.

Luna stood slowly, and Levi’s breath caught in his throat as her massive figure rose to her full four-inch height. Even at this size, she was an imposing presence, her movements effortlessly confident. She walked toward the tiny couch, plucking up one of the decorative pillows with a giggle.

“Adorable,” she cooed, tossing the pillow back onto the couch before plopping herself down. The furniture creaked under her weight, comically undersized for her, but she didn’t seem to care.

Levi sat on the floor, watching her warily. Behind her, the massive expanse of her bedroom loomed beyond the apartment’s window—a chilling reminder of her full size and the terrifying power she could wield with just the press of a button.

“Come on, bro,” Luna said, patting the small space beside her on the couch. “Sit down. Let’s talk.”

“Talk about what?” Levi snapped, his frustration boiling over. “About how you’ve turned me into your fucked-up little toy?”

Luna’s expression faltered for a moment, her grin softening into something more serious. She sighed, brushing a stray lock of hair from her face. “That’s… part of it, yeah,” she said quietly, her voice tinged with a rare hint of vulnerability.

He was momentarily taken aback by her confirmation, his mind racing as he tried to process her words. After weighing his options, he decided his safest bet was to remain silent for now, his jaw tightening as he stared up at her.

Luna’s towering figure shifted slightly, her posture more tentative than usual. She seemed to hesitate, her usual confidence replaced with something softer—an emotion he couldn’t quite place. Her gaze wandered around the pink apartment, a vivid reminder of just how completely she owned him. It wasn’t just the physical space she controlled, it was him. Every fiber of his being was trapped in her little world.

Finally, she looked back at him, meeting his eyes with a nervous smile.

“Look, Levi…” she began, crossing her legs and fidgeting with the tiny pillow next to her. Her fingers toyed with the delicate edges, an uncharacteristic sign of her uncertainty. “I know I’ve been… intense,” she admitted, her tone softer than he’d heard in days.

He blinked up at her, his body stiff against the plush pink carpet beneath him. The surreal absurdity of the situation didn’t escape him—trapped in a dollhouse-sized apartment, his giant sister looming over him, now suddenly talkative. Part of him wanted to lash out, to scream at her for everything she’d done, for every degrading moment she’d forced him to endure. But he bit his tongue, knowing that lashing out would only end in more humiliation. She had the power here.

Luna’s lips quirked into a faint, almost self-deprecating smile. “I mean, let’s be real,” she continued, a nervous chuckle escaping her lips. “I’ve kind of been… living out my wildest fantasies with your tiny body, haven’t I?”

Levi’s eyes narrowed, his blood boiling at the casual admission. “That’s one way to put it,” he spat through gritted teeth.

Her smile grew wider, unrepentant. “Well, that is how I put it,” she said, her tone light as if they were having a casual sibling chat. She stood up suddenly, walking to the tiny TV mounted on the wall. She marveled at the design for a moment, her fingers brushing the edges, before turning it off with a small laugh. “This thing is adorable. Honestly, everything in here is just…” She sighed, trailing off as she turned back toward him, walking to the couch and sitting back down.

Her fingers picked at the tiny pillow again, her movements distracted. “But you know,” she continued, her voice quieter now, “I don’t want to hurt you, Levi. I hope you know that.” She glanced at him, her expression softening as guilt flickered across her face. “Like, I know I’ve been pushing boundaries—our boundaries—but it’s not like I want to break you. You’re still my brother.”

Levi’s gaze hardened, his fists clenching at his sides. “That’s one way to put it,” he repeated, his voice sharp.

Luna shook her head, her lips quirking into a faint smile. “No, I mean it. I just…” She sighed, leaning back against the comically small couch, which groaned under her weight. “I don’t know, Levi. This whole thing—it’s exciting, okay?” She giggled nervously, her cheeks flushed as she avoided his gaze. Her fingers fiddled with the pillow again, a rare crack in her usual dominance. “It’s like… I feel so alive. So powerful.”

Her words cut through him like a knife. He shuddered, her admission landing heavily on him. She wasn’t just toying with him because she could—she thrived on it.

“I mean,” she continued, her voice growing more animated as she leaned forward slightly, “you have no idea what it’s like, Levi. Seeing you so tiny, so helpless in my hand…” Her lips curved into a grin, her tone shifting to one of playful arousal. “It’s… taboo, isn’t it? Completely wrong. And yet, it’s so… wonderful.” She sighed, almost dreamily, her fingers brushing her thigh as she bit her lip.

Levi felt a surge of anger bubbling up inside him, but before he could unleash it, she sat up abruptly, her expression shifting.

“But!” she said quickly, her voice firmer now. “Sometimes…” She hesitated, her grin faltering for just a moment. “Sometimes I wonder if I’m going too far. Like… am I breaking you?” Her voice grew quieter, the question hanging heavily between them. “You know, like… mentally?”

Levi froze, his breath catching in his throat. He hadn’t expected her to admit something like that. For a moment, he was at a loss for words. This was new territory—Luna showing vulnerability, even doubt. He had to tread carefully.

“Well…” he began slowly, his voice carefully measured. “I think by asking that question, you already know the answer.”

Her eyes flickered with guilt, and for a fleeting moment, he thought he might have struck a chord. But then her lips curled into a sweet, disarming smile.

“That’s why I came to talk to you,” she said softly, her tone almost reassuring. She stood suddenly, moving with deliberate grace as she stepped closer to him and crouched down. He flinched instinctively, her size still overwhelming even at four inches tall.

Her gaze locked onto his, and a familiar glint of mischief sparkled in her eyes as she smiled wider. “Because I think you’re wrong,” she said with a grin, her voice dripping with confidence.

Just as Levi was about to respond, Luna grinned and held up a finger to her lips, shushing him like a child throwing a tantrum. “Shh,” she giggled, her tone dripping with mock sweetness. “Let’s talk about this later, okay?”

His fists clenched at his sides as his frustration boiled over. “Later? No, Luna, I want to talk about it now—”

But she was already up, ignoring his protests as she wandered off toward his bedroom. “Wow, this place is so cute!” she called out, her voice echoing from the other room.

Levi groaned, muttering under his breath as he reluctantly stood. “I swear, she’s impossible.”

From the bedroom, he could hear the creak of his miniature bed as she climbed onto it, followed by a whistle of approval. “Ooh, comfy! A bit small for me, though,” she laughed, the sound of her shifting weight making him cringe. “But for you? Perfect size, bro!”

He stayed rooted in the main room, refusing to give her the satisfaction of chasing after her. When she finally reappeared, her grin was as wide as ever. She practically skipped back into the room, looking far too pleased with herself.

“So,” she began, plopping down onto the couch, her long legs sprawled out. “What now?”

Levi glared at her. “You tell me,” he said flatly.

Luna gestured around the pink apartment with a playful wave of her hand. “We hang out! You know, get comfortable. Just a brother and his little sister chilling together,” she giggled, leaning forward to rest her chin in her hands.

He scoffed, his eyes flicking to the enormous window behind her that framed the surreal expanse of her bedroom. “Comfortable? In this… this fucked-up dollhouse of yours?”

She laughed, unabashed. “Well, yeah. It’s cute!” Her eyes sparkled with amusement as she added, “Besides, you are a doll, right? My doll.” She giggled, leaning back against the couch. “Can you imagine telling your younger self that someday you’d end up as your little sister’s doll? Bet he’d love that.”

Levi gritted his teeth, her words striking a nerve. He hated how casually she wielded her power over him, like it was some sort of harmless joke.

Luna stood up again, her attention drawn to the window. She pressed her face against it, peering out at her colossal bedroom. “I must look huge at my normal size, huh?” she mused, her tone a mix of wonder and playful teasing.

He stayed silent, his arms crossed over his bare chest as he watched her. Her figure loomed large against the backdrop of her massive world, and he hated the way it made him feel so small—so insignificant.

She turned back to him after a moment, her face lighting up with a grin as she walked back to the couch. “It’s cute,” she said with a nod, plopping down and picking up one of the tiny decorative pillows. “Adorable, even.”

“I hate it,” Levi muttered, his voice low and bitter.

Luna pouted dramatically. “Oh, come on.” She patted the cushion beside her, her grin returning. “Sit down. Relax. I don’t bite… much,” she added with a wink.

He sighed heavily but reluctantly moved to sit across from her, his posture stiff as he tried to keep his distance. She giggled, nodding approvingly. “There you go,” she cooed, plucking at the tiny pillow in her lap. “You know, this place is way too girly for you.”

“Yeah, well, you put me in here,” he snapped, his eyes darting to her wristwatch, wondering if he could somehow get to it.

She laughed, tossing the pillow aside. “Fair enough.”

An awkward silence followed, the tension in the room palpable. She leaned back, studying him with an intensity that made his skin crawl. He avoided her gaze, his face burning with shame as memories of the past few days flooded his mind—being pressed against her, inside her, reduced to nothing more than a plaything for her amusement.

Luna tilted her head, her grin softening into something more contemplative. She could sense his unease, the way he bristled under her gaze. The silence stretched on until finally, she decided to break it.

“So…” she began, her voice light and teasing. “Want to talk about the past few days?” She giggled, leaning forward slightly. “Like… do you want to talk about everything I’ve done with you?”

Levi’s head shot up, his eyes narrowing as he glared at her. She met his gaze with an almost predatory grin, her fingers tracing the edge of the couch as she waited for his response.

Levi’s head snapped toward her, his glare sharp and venomous, his entire body trembling with anger and frustration.

"Are you serious right now?" he spat, his voice low and shaking, barely able to contain himself.

Luna tilted her head, her lips curling into that maddening grin. "Oh, absolutely," she replied breezily, leaning back on the ridiculously tiny couch. "Come on, let it all out. I want to hear it, every single thing. Vent. Scream if you have to. You’ve been through a lot, haven’t you, little bro?"

His fists clenched at his sides, and for a moment, he could only stare at her in disbelief. Then, like a dam bursting, his emotions erupted.

"Fine! You want me to vent? Let’s talk about it!" he barked, pacing back and forth across the pink carpet.

He began listing everything, his voice growing louder with each word, his face twisting with anger. "You’ve swallowed me whole, Luna! Do you have any idea what it feels like? To be sliding down a throat, knowing you’re about to be digested alive? To be churned around in your sister’s stomach like some piece of food?!"

Luna’s grin widened, her eyes alight with amusement.

"And that’s not even the worst of it!" he continued, his voice rising in pitch as his rage built. "You stuffed me inside your pussy! Your fucking pussy! Like I was some… some goddamn sex toy for your pleasure!" His words were almost incoherent with fury now.

Luna leaned forward slightly, resting her chin in her hand, her grin never faltering.

"And let’s not forget the time you turned me into your personal insole." His pacing stopped, and he turned to her, his face red with a mix of anger and humiliation. "Do you know what it’s like, Luna? To be inside your sweaty shoes on a hot day? To feel your weight crushing me over and over, tasting your sweat, supporting you with every single goddamn step?!"

Luna raised a single eyebrow, clearly enjoying herself.

"And yet…" she said softly, interrupting him, her tone dripping with playful condescension.

Levi froze, his hands balling into tight fists at his sides. "What?" he growled, his voice shaking.

Her gaze dropped pointedly, her grin growing even wider. "You’re hard right now," she said, her voice light and teasing, but with a sharp edge that cut deep.

Levi’s entire body went rigid, his breath catching in his throat.

"That’s the app!" he shouted, his face flushing a deep red as he pointed accusingly at her. "You’re the one keeping me like this! It’s not me!"

Luna’s grin turned into a soft, knowing smile. "Oh, really?" she said, raising an eyebrow. With deliberate slowness, she tapped a few times on her watch before turning the screen toward him.

"See for yourself," she said sweetly, her voice tinged with barely-contained laughter.

Levi’s eyes darted to the screen, and his heart sank. The "Erection Control" setting was off.

His jaw dropped, his mind scrambling for an explanation.

"So…" Luna said, her tone light and airy, like they were discussing the weather. She leaned back again, crossing her legs and resting an arm along the back of the couch. Her expression was the perfect combination of mock innocence and devilish amusement. "Maybe it’s not the app after all."

Levi’s mouth worked soundlessly, his face a storm of emotions—humiliation, anger, disbelief. "That’s… that’s impossible," he muttered, more to himself than to her.

Luna’s giggle filled the room, light and carefree, yet devastating in its condescension. "Oh, Levi," she said, shaking her head. "You felt all those things. You hated every second of it, didn’t you?" Her grin widened, her voice lowering as she leaned in slightly, her gaze locking onto his. "And yet… here you are, rock hard. Your body doesn’t lie, little bro."

Her words hit him like a physical blow, and he staggered back a step, his humiliation boiling over into a mix of anger and despair. "You don’t get it!" he shouted, his voice cracking. "This isn’t me! I don’t… I can’t—"

Luna interrupted him with a laugh, shaking her head again. "You can keep telling yourself that, but we both know the truth, Levi." She leaned forward, her grin taking on a wicked edge. "You might hate me for what I’ve done to you. But a part of you… loves it."

Levi gritted his teeth yet again, his frustration boiling over—a sensation that had become all too familiar since she had shrunk him and trapped him in this pink nightmare of an apartment. He couldn’t even count the number of times he’d felt this raw mix of shame, anger, and helplessness. And yet, what burned him even more was the undeniable truth: some twisted part of him liked it.

The thought made his skin crawl. He was aroused. Fully erect. Right in front of his own sister. It was mortifying, humiliating, wrong on every conceivable level. But it was also what made it so inescapably consuming. Being dominated like this—completely and utterly powerless—was bad enough. But the fact that it was her doing it? His playful, bratty sister? That just made it worse… and somehow, shamefully, all the more intoxicating.

His eyes darted around the apartment in search of anything to cover himself with. After a moment, he spotted a tiny blanket folded on the miniature bed. He snatched it up and wrapped it tightly around himself, cursing under his breath. Why hadn’t he thought of this earlier? Was he really becoming that accustomed to being naked in front of her?

She, of course, noticed immediately. Luna giggled, the sound both mocking and sweet. "Oh, come on, Levi. As if we need to be modest around each other now," she teased, her voice dripping with amusement. "I mean, really," she added, smirking as she leaned slightly closer. "You’ve been inside me more ways than any man alive. You’ve seen all my parts."

Her words sent a hot wave of embarrassment washing over him, his face flushing red as he tightened the blanket around himself. His glare only seemed to make her grin wider.

"You’re disgusting," he spat, his voice shaking with anger.

"Disgusting?" she echoed, feigning offense before breaking into another giggle. "Oh, relax, little bro. It’s just us. No need to be shy."

Her teasing had the desired effect; he felt his anger flare even hotter, though he stayed rooted to the tiny barstool at the faux kitchen in the corner of the room. He needed distance from her, as much as the cramped space would allow.

Luna, noticing his rising frustration, softened slightly. She sat back and crossed her legs, her grin fading into something a touch more serious. "Okay," she said after a moment, her tone taking on a surprising edge of sincerity. "Here’s why I came down to your level to talk with you."

His stomach churned at her choice of words: your level.

Levi stared at her warily, his arms crossed over the blanket covering his naked body. "Well, this should be good," he muttered, his voice thick with sarcasm.

Luna ignored his jab, brushing it aside like she always did. "It is good, Levi," she said, her smile returning—sweet, almost disarming. "Just… hear me out, okay?"

She stood up and took a step closer, closing the already small gap between them. Her presence loomed over him, even at this size, as she settled onto the tiny stool beside him. The piece of furniture groaned under her weight, comically small for her still-larger frame. She smirked, catching him glancing at her awkwardly perched position.

"Eyes up here, little bro," she teased, leaning slightly toward him.

Levi flinched and scowled. "That’s not what I was doing," he snapped defensively.

"Sure, sure," she giggled, cutting him off. She adjusted her position slightly, making herself even more comfortable as she leaned one elbow on the tiny counter. "Now, here’s the deal," she began, her tone shifting to something almost conspiratorial.

Levi narrowed his eyes at her, his skepticism palpable.

"After we finish this little chat," she said, gesturing vaguely around the pink apartment, "I’m going to grow back to my normal size." She paused, letting her words hang in the air for a moment before continuing. "But I’ve decided to keep you like this for a little while longer."

"Excuse me?" Levi snapped, his voice rising.

"Relax," she said, holding up a hand to calm him. "I’m thinking… a few more days. Three, maybe four. Tops."

"You’re thinking?" he growled, standing abruptly. The blanket slipped slightly, but he didn’t care. "You don’t own me, Luna!"

She arched an eyebrow, her playful smirk returning. "Don’t I?" she said softly, her words dripping with amusement.

He glared at her, his fists clenching at his sides. "And what the hell does ‘testing the waters’ even mean?"

She stood as well, her hands firmly pressing down on his shoulders as she gently forced him back into the stool. Her touch was firm but not rough, her strength far greater than his. "It means," she said calmly, "that I’m going to play with you a little more. But I’ll also check in—make sure you’re not… breaking."

"Breaking?" he echoed, his voice filled with disbelief.

"Yes, breaking," she said simply, her tone matter-of-fact. "I mean, I’m not a monster, Levi. I want to make sure you’re still you by the end of this. That’s fair, right?"

"Fair?" he repeated incredulously, his voice trembling with anger. "You think this is fair? You’ve shoved me into your shoes, stomped on me for hours, swallowed me, used me as a sex toy—and now you’re talking about what’s fair?!"

Luna sighed, her hands still resting on his shoulders. "I’m trying, okay?" she said, her voice softening. "But this isn’t just about you. This is about us."

"Us?" Levi hissed.

Before she could answer, he saw his chance. His hands shot up to grab her wrist, his fingers fumbling with the clasp of her watch. His heart raced as he tugged at it, trying to pry it off her arm.

For a moment, Luna didn’t react. She just stood there, watching him struggle with an amused smile. Then, as he managed to turn her arm and continue fumbling with the clasps, she giggled.

"Really, Levi?" she said, her tone dripping with amusement.

He froze, looking up at her.

She smirked, her free hand tapping the screen of the watch. "Electronic locks," she said smugly. "You can’t open it without the password." She leaned in closer, her voice lowering to a teasing whisper. "Feel free to keep trying, though. There’s only… oh, I don’t know, a trillion possible combinations."

Levi’s heart sank as her words sank in.

"Nice try, little bro," she said with a wink, pulling her wrist free from his grasp effortlessly. "But like I said, I’m in charge here."

Levi stared up at her, defeated, the fight draining from him. He knew deep down he had no choice in the matter. No amount of resistance could change the reality of his situation. With a heavy sigh, he released her wrist, feeling even more pathetic than before.

Luna smiled down at him, her fingers instinctively reaching out to ruffle his hair, a playful gesture that felt all the more demeaning now. "Good boy," she cooed. "So, are you ready to listen to my deal now?"

He didn’t answer, his jaw clenched tightly, but the lack of protest was enough for her to continue.

"Okay, so here’s how it’s going to go," she said, her tone light and casual as though she weren’t talking about continuing to completely dominate her own brother. "We’re going to test the waters for a few more days." She paused to let the words sink in, her fingers absently flicking the edge of a tiny decorative pillow on the couch.

She grinned down at him, her tone turning sing-song. "I’ll keep playing with you, doing whatever I want." She watched his body tense, and her grin widened. "But," she emphasized, holding up a finger for dramatic effect, "I’m also going to check in with you like this every few days to… reevaluate."

Levi’s stomach churned, his mouth dry as the weight of her words settled over him. "Reevaluate?" he repeated, his voice barely above a whisper.

She nodded enthusiastically. "Mhm! Like, see how you’re holding up. You know, make sure you’re still… functional."

He blinked at her, his voice sharper this time. "You mean see if I’m broken enough for you yet?"

Luna sighed theatrically, running a hand through her long hair. "No, Levi. Don’t be so dramatic," she said, though the glint in her eye told him she didn’t mind his reaction. "I know you. You’re way too strong to actually break. If anything, you’re resilient, which I gotta say, makes you even more fun to play with." She giggled, a twisted compliment that only made him grit his teeth harder.

"But," she continued, turning a tiny plastic drinking cup over in her hands as she spoke, "I might conclude that… maybe it’s been enough for this holiday. Maybe."

He frowned, his heart racing. "What does that mean?"

Luna looked at him with a mischievous grin, her eyes sparkling with that familiar bratty energy. "It means," she said slowly, deliberately, "that I’ll decide whether to return you to the shrinking center and ship you back home—enlarging you in the process, of course."

Levi felt a flicker of hope.

"Or…" she added, her grin widening devilishly.

His stomach dropped.

"Or," she repeated, savoring the moment, "I keep you like this for the rest of the holiday." She laughed softly, seeing the horror dawn on his face. "Which, by the way, is still two more weeks."

His blood ran cold. "T-two weeks?" he stammered, his voice trembling as he tried to process her words.

"Yep!" she chirped, her tone bright and cheerful, like she was announcing a surprise vacation.

Levi’s mind reeled. Two more weeks of this. Two more weeks of being her toy. Two more weeks of being shoved into her shoes, her body, her everything. Two more weeks of her laughter ringing in his ears, her teasing voice mocking him while she shoved him into places he didn’t want to think about. Two more weeks of smelling her, tasting her, being completely dominated by her whims.

She saw the panic in his eyes and giggled softly, leaning forward. "Don’t look so scared, little bro. It’s not that bad. You’re rock hard, like, half the time anyway," she teased, her voice a mix of playful and sultry.

Levi’s face flushed a deep red. "That’s the app," he snapped, his voice shaking with frustration. "It’s keeping me like this!"

"Is it?" Luna asked, cocking her head to the side as though genuinely curious. "Or is it just that tiny part of you that… likes this?" She leaned closer, her grin widening as she saw him squirm under her gaze.

He turned his head away, unable to meet her eyes.

"Come on," she purred, her voice dropping to a teasing whisper. "You’re telling me you hate being my little toy? Even when I…" She trailed off, letting his imagination fill in the blanks.

"You’re insane," he muttered, his voice barely audible.

She giggled, clearly delighted. "Maybe a little," she admitted, sitting back and crossing her legs.

"So what happens if I say no to your stupid deal?" Levi demanded, his voice louder this time.

Luna shrugged, completely unbothered by his defiance. "Then I’ll still do what I want," she said simply. "But I’d rather have you on board with it. It’s more fun that way."

He glared at her, his fists clenching at his sides. "You’re giving me a choice that’s not a choice."

She smirked, tilting her head as though considering his words. "It’s the best I can do," she said with a casual shrug.

The way she said it, so calm and matter-of-fact, sent a shiver down his spine. This wasn’t a conversation. It was a declaration. She was in control, and no matter what he said, that wasn’t going to change.

Levi’s silence was a thin shield, but one he clung to desperately. He refused to dignify her outrageous suggestions with an answer, even as her gaze bore into him with that infuriating mix of amusement and affection. His defiance only seemed to embolden her.

Luna stretched lazily, checking her watch. "I should probably get moving soon," she mused, her voice casual, as if this were just any ordinary day. "Mom’s making risotto, and I want to squeeze in a swim before dinner. Oh, and later, Jenny and I are hitting up that new band in town!" She grinned down at him like she was discussing weekend plans with a friend, not her shrunken, naked, utterly humiliated brother.

Levi seized the opening, desperation driving his words. "Just listen to yourself, Luna. What do you think Mom would say about all this?" He gestured to the pink apartment, to his own diminutive form, to the sheer insanity of their situation.

She laughed, a light, carefree sound that only deepened his dread. "Oh, she’d be horrified," she admitted with a shrug, hopping off the miniature barstool with ease. "But she doesn’t have to know, does she?" Her eyes gleamed as she took a deliberate step closer, towering over him. "I’ll make sure you’re nice and hidden. You know how good I am at that," she purred, her tone teasing but dripping with the weight of her earlier games. "Whether it’s inside me or tucked away in my shoe, I’ve got plenty of spots to keep you out of sight."

Levi flinched, the memories of her "hiding spots" flooding back unbidden. Her stomach, her underwear, her relentless shoes—each one more degrading than the last.

"Look," Luna said, her tone softening slightly as she crouched down, placing a hand on his trembling shoulder. Her fingers felt massive, easily engulfing the upper part of his arm. "I know this is… a lot for you." Her words were gentle, but the smirk tugging at her lips betrayed her enjoyment. "But maybe," she continued, her voice lowering to a whisper, "if you stop fighting it, you’ll actually enjoy it."

His jaw clenched, his shoulders stiffening under her grip. "Enjoy it?" he spat. "Enjoy being your toy? Enjoy being shoved into your underwear or swallowed whole? Should I enjoy being stomped on in your shoes all day, tasting your sweat?"

Her giggle was maddening, light and bubbly like she didn’t have a care in the world. "Well, yeah," she said, her grin widening. "All of it. Why not?"

He ran a hand through his hair, his frustration palpable. "This is insane, Luna."

"Maybe," she said with an exaggerated shrug, standing up and towering over him again. "But you’re stuck with me, little bro. You’re my toy now, so why not make the most of it?" She leaned down, her face filling his entire view as her voice dropped to a playful whisper. "Come on, embrace your submissive side. Do it for your big sis."

Levi scowled up at her, his fists clenched. “This isn’t a deal at all, Luna. It’s just you doing whatever you want and pretending I have a choice.”

Luna tilted her head, her grin faltering slightly, though the sparkle of mischief in her eyes didn’t fade. “Oh, come on, bro,” she teased, brushing her hair over her shoulder. “You’re just mad because you’re not getting your way. I’m offering you a compromise—"

“Compromise?” Levi snapped, cutting her off. “You’re still playing with me, humiliating me, treating me like… like some toy, Luna! There’s nothing fair about this!”

Luna shrugged, her grin returning. “Fair is boring,” she said simply, her voice light and teasing. She leaned in closer, her eyes gleaming. “But fine. If my deal isn’t good enough for you, why don’t you come up with one instead?”

Levi blinked, caught off guard by the sudden turn. “What?”

She crossed her arms, towering over him even at her reduced size, her expression one of mock impatience. “You heard me. If you don’t like my idea, then you come up with a better one. Go on.” She gestured dramatically, like she was handing him the stage. “I’m all ears.”

He glared at her, his mind racing. But what could he even say? What could he possibly offer her that would stop her from treating him like a plaything? Every scenario he thought of ended the same way—with her winning, with her getting exactly what she wanted.

“Well?” she asked, tapping her fingers against her arm. “I’m waiting.”

“I…” Levi hesitated, his frustration boiling over. “I don’t have one, okay? Because there is no deal where I win. You’ve already decided how this is going to go.”

Luna chuckled, shaking her head. “Oh, little bro, you’re such a pessimist,” she said with a sigh. “Fine, if you can’t come up with anything, I will.”

Levi flinched at the sudden glint in her eye, a sinking feeling settling in his stomach. “What now?” he muttered warily.

Luna’s grin widened, and she crouched down, bringing her face closer to his level. Her gaze lingered on him, making him squirm under her scrutiny. “You know,” she began, her tone dripping with amusement, “there’s one thing you can’t seem to hide from me, no matter how much you try.”

He frowned, confused. “What are you talking about?”

She leaned in closer, her voice lowering to a conspiratorial whisper. “Your erections, Levi.”

His face turned bright red, and he instinctively covered himself with his hands, though it did little to hide the truth. “Luna, stop—”

“No, seriously,” she interrupted, laughing softly. “You can act all high and mighty, pretend you hate every second of this, but your body tells a different story, little bro. Every time I tease you, every time I… play with you, there it is, standing at attention.” She giggled, leaning back and crossing her arms. “It’s adorable.”

“Shut up,” Levi growled, his voice trembling with humiliation.

“Oh, don’t be like that,” Luna cooed, clearly enjoying his discomfort. “In fact, let’s make it interesting.” Her grin turned wicked, and she tapped a finger against her chin, pretending to think. “How about this for a deal: if you can keep it together—let’s say, no more than ten erections over the next three days—I’ll take you to the shrinking center and send you home. No more games, no more teasing.”

Levi’s heart skipped a beat. “And if I can’t?”

Her grin widened, her eyes sparkling with delight. “Then you’re mine for the rest of the holiday,” she said, her voice light and playful, as though she were proposing a friendly wager and not threatening to keep him as her personal toy for two more weeks. “Deal?”

He stared at her, his mouth dry. “That’s insane.”

“Is it, though?” Luna asked, tilting her head innocently. “You’re the one who keeps saying you hate all this, that you’re not enjoying it. So prove it. If you’re really not into it, this should be easy for you. Right?”

Levi’s mind raced. She was setting him up, he knew it. The humiliation, the teasing, the way she toyed with him—it was all designed to break him, to push him to the edge. There was no way he could go three days without—

“Well?” Luna prompted, her voice sing-song and taunting. “What’s it going to be, bro? Do you have the self-control to win your freedom? Or are you going to admit that you like being my little toy?”

“I don’t like it,” Levi snapped, his face burning with shame.

“Then take the deal,” she challenged, leaning closer, her grin widening. “Unless, of course, you’re afraid you’ll lose.”

He gritted his teeth, his fists clenching at his sides. She was backing him into a corner, and she knew it. But what choice did he have? If he refused, she’d take it as proof that he enjoyed being her plaything. And if he accepted… well, at least there was a chance, however slim, that he could win.

“Fine,” he muttered finally, his voice barely above a whisper. “Deal.”

Luna clapped her hands together, her laughter ringing out like a victory cry. “Perfect! This is going to be so much fun,” she said, her eyes gleaming with excitement. “Oh, and don’t think I’ll make it easy on you, little bro. I’m going to be watching very closely.” She winked at him, her smile wide and triumphant. “Good luck.”

Levi swallowed hard, his heart pounding in his chest. He had no idea how he was going to survive the next three days. “

Luna stretched her arms with a satisfied sigh, the grin on her face making Levi’s stomach churn. She turned her attention back to him, her eyes sparkling with mischief. “I really enjoyed our little chat, you know,” she said, her voice airy and playful. “It was… refreshing.”

Levi glared up at her, his jaw clenched. “Yeah, well, I didn’t.”

Her grin only widened as she ignored his response. “I think it really helped us bond. Don’t you think so, bro? A little heart-to-heart to strengthen our sibling connection?”

“Bond?” he spat. “You’ve turned me into your—”

She giggled and cut him off by holding up her hand. “Yeah, yeah, my toy, I get it.” She shrugged as if it was the most natural thing in the world. “I mean, you can call it whatever you want. I think we’re having fun.”

Levi wanted to scream at her, but before he could, she spun on her heel and strolled toward the tiny dresser in the corner of the apartment. “Anyway,” she said cheerfully, “I need to put this away.” Without a hint of shame, she pulled her dress off over her head, letting it drop to the floor. She stood there, completely naked, her toned body looming over him. “You know,” she mused, holding up the tiny dress, “this thing is so cute. I mean, look at it! A tiny little dresser for a tiny little girl.” She laughed as she folded the dress and placed it neatly inside.

Levi’s face burned as he tried to look anywhere but at her, but there was no escaping the sight of her towering naked form. She seemed to notice his discomfort, her grin turning wicked as she turned back toward him. “What’s the matter, Levi? You’ve seen everything already. Don’t act shy now.”

He didn’t respond, his silence only encouraging her further. She stepped closer, her bare feet padding softly against the carpet, until she was standing directly in front of him. She fiddled with the watch on her wrist, her fingers dancing over the controls. “Time to grow back,” she said, winking as she tapped in her password.

But then she paused, her eyes lighting up with a new idea. “Hmm…” she murmured, biting her lip as she stared at the watch.

Levi’s heart sank. He could tell by the way she glanced at him, her grin widening, that whatever she was planning was going to be bad. “Luna,” he said cautiously, taking a step back. “What are you doing?”

“Oh, nothing,” she said innocently, her tone betraying her amusement. “Just a little experiment, that’s all.”

Before he could protest, he felt it. A strange tingling sensation coursing through his body. His heart raced as he looked down at himself, his legs wobbling as he realized what was happening.

“No,” he whispered, taking a step toward her. “No, Luna, don’t—”

But she was already laughing, her fingers still tapping at the controls. “Let’s make this cute little apartment really big for you, little bro,” she said, her voice dripping with delight.

Levi stumbled as the world around him began to expand. No—not expand. He was shrinking. The pink carpet fibers beneath his feet seemed to rise around him like a forest, the furniture growing impossibly large.

“Luna, stop!” he shouted, running toward her. He barely reached her ankle before she crouched down, her grin enormous and wicked as she watched him dwindle further.

“Oh, come on, Levi,” she teased, her voice booming in his ears. “This is just too good.” She wiggled her toes, her grin turning even more mischievous. “Let’s see how small we can go.”

His heart pounded as his body continued to shrink, the apartment around him transforming into a surreal landscape. By the time the tingling stopped, Luna was a towering giantess to him even at her reduced four-inch height. She lifted her foot, her massive toes hovering above him like living boulders.

“Look at you,” she said, poking him gently with her big toe. The force sent him tumbling into the pink carpet fibers, his tiny body completely overwhelmed by the strands that now rose around him like trees. “You’re so tiny, Levi. It’s adorable.”

He struggled to stand, his movements clumsy and slow as he pushed his way through the dense fibers. The sight of her massive foot moving above him made him dizzy with both fear and humiliation.

“Enjoy your new surroundings,” Luna teased, her laughter echoing around him. “It’s like a whole new world for you, isn’t it?”

Before he could respond, she straightened up and began tapping at her watch again. Levi could only watch in horror as she started to grow, her already massive form becoming utterly incomprehensible. The pink apartment around him seemed to vanish into the distance as her body expanded, her bare legs stretching higher and higher until they disappeared into the heavens.

Luna stopped growing when she was about a foot tall, her figure now utterly dominating the space. She stepped out of the apartment, the ground trembling beneath her feet as she walked into the vast expanse of her bedroom. Levi stared after her, his tiny body trembling with fear and humiliation.

“See you soon, little bro,” she called over her shoulder, her voice like thunder in his ears. “Try not to get lost down there!”

She tapped her watch again, and he watched as she resumed growing, her figure becoming an impossible monument that towered over the pink apartment. By the time she reached her full height, she was a goddess to him, her laughter booming like the sky itself.

Levi fell to his knees, his breath coming in short gasps as he tried to comprehend the sheer scale of her. The thought of spending even a moment at this size in her presence was almost too much to bear.

Luna crouched down, her face filling the sky as she peered through the window of the tiny apartment. “Don’t go anywhere, little bro,” she teased, her grin wide and wicked. “I’ll be back soon to check on you.”

And with that, she turned and walked away, her footsteps shaking the ground as she disappeared into the distance. Levi was left alone, trapped in the pink prison of the apartment, surrounded by the looming, incomprehensible world of his sister’s room.

Levi scrambled backward, his heart pounding as the apartment trembled under her massive movements. Then she knelt down, and her impossible, planet-sized face loomed into view beyond the apartment's window. Her eyes, twin oceans of blue, squinted as she peered inside, her breath fogging up the glass slightly.

“Wow,” she murmured, her voice rumbling like distant thunder, “just seconds ago, I was in that thing.” She chuckled softly, the sound rolling over him like a wave. “It’s crazy, I actually shrunk myself down. That was… wild.”

Levi pressed himself against the far wall of the apartment, trembling as her massive eyes scanned the interior. She was too big—too enormous. He wasn’t just small; he was a speck in her world, completely at her mercy.

“Now,” she muttered, her gigantic face filling the window again as her gaze darted around, “where did I shrink you down to, little bro?” Her breath, hot and humid, clouded the glass, and he shivered as the faint condensation dripped down like rain.

She leaned closer, her colossal pupils narrowing as they finally locked onto him. For a moment, he hoped she hadn’t really spotted him, but then her expression lit up with unmistakable recognition.

Her laugh erupted, a deafening roar that shook the apartment to its core. Her mouth opened wide, revealing teeth that glistened like ivory skyscrapers. “No way, bro!” she squealed, her booming voice making him flinch. “You’re sooo tiny!”

Levi stared in disbelief, paralyzed as he looked at her massive mouth. It was a cavern of wet, glistening flesh—her teeth alone were bigger than houses to him, shining under the faint glimmer of her saliva. Her tongue, pink and undulating, was like an enormous, slimy field stretching back endlessly. The thought of being tossed into that wet abyss sent a cold shiver down his spine. He could picture himself stuck to one of her massive teeth, helpless and unable to move, or lost somewhere on her tongue, swallowed up by her humiliating wetness. No! This was too much—it was too much to even think about.

But Luna didn’t seem to notice his terror. Her grin widened as her enormous hand hovered above the apartment, her massive finger descending toward the button on top of the shrinkbox.

He braced himself, clutching the edge of the furniture as her finger pressed the button with terrifying force. The apartment jolted violently as it slid back into the shrinkbox, the sound of mechanisms clicking and grinding echoing like thunder around him. He gasped as he was thrown to the ground, the motion making him feel even smaller—if that was even possible.

“All right, bro,” her voice boomed cheerfully from above. “Don’t worry! I’m just going to pee real quick, and then I’ll grow you a bit, okay? Must be scary down there!” She giggled at her own words, clearly amused.

“Scary” was a catastrophic understatement, but he didn’t dare respond. Even if he could, she wouldn’t hear him, and even if she could, she probably wouldn’t care. She was too absorbed in her own excitement to grasp the sheer terror of his situation.

“Man,” she continued, laughing softly, “I’m definitely going to play with you like this soon. Can you imagine all the fun we’ll have, little bro?” She clapped her hands together, her voice dripping with excitement.

Levi could barely breathe, the air around him heavy with her presence. She didn’t understand—she couldn’t. To her, this was a game, a thrilling new experience. To him, it was a nightmare.

Her enormous shadow shifted as she stood up, her towering form retreating from the shrinkbox. “Okay, be right back!” she called, her voice playful as she disappeared into the bathroom. The ground trembled faintly under her footsteps, each one a reminder of her immense power.

---

Levi slumped to the pink carpet, his knees weak as the ground beneath him finally stopped shaking. He rubbed his temples, trying to comprehend everything that had just happened. Luna had shrunk herself—his towering, all-powerful sister had willingly made herself smaller to talk to him, only to immediately twist the situation back into her favor. She had dangled the illusion of choice in front of him, only to pull it away at the last second, making it clear she held all the cards.

And then there was the dare.

He let out a bitter laugh, the sound hollow and humorless. Ten erections in three days. If he failed, she’d keep him like this for the rest of the holiday. He couldn’t believe he’d even entertained the idea, let alone agreed to it. But what choice did he really have? Luna had already proven time and again that she would do whatever she wanted, regardless of his protests.

His stomach churned as he thought back to the way she’d looked at him when she proposed it—so playful, so confident, like she knew he would lose. And the worst part? She might be right.

Levi buried his face in his hands, his mind replaying the events of the past few days in excruciating detail. Being stuffed inside her underwear, pressed against her skin as she walked around like he wasn’t even there. Being swallowed alive, her tongue smearing him with saliva as she toyed with him before sending him plunging into the suffocating depths of her body. And then there were the moments she’d used him for her own pleasure, reducing him to nothing more than a tool for her gratification.

He shuddered, a wave of disgust washing over him—but it wasn’t directed solely at her.

Why am I like this? he thought, his hands trembling as he clenched them into fists. Why is there a part of me that’s… aroused by this?

He didn’t want to be. He wanted to hate every second of it, to fight her with every ounce of strength he had. But his body refused to cooperate. His arousal betrayed him time and time again, and Luna saw it. She knew.

Levi’s fists clenched tighter, his nails digging into his palms. I won’t let her win, he thought desperately. I’ll control myself. I have to. But deep down, he wasn’t sure he could. Not with the way she looked at him, the way she touched him, the way she knew exactly how to push every one of his buttons.

A loud flush echoed from beyond the window, and Levi’s heart skipped a beat. She was coming back.

---

The world trembled once again as Luna returned, the thudding of her footsteps reverberating through the tiny apartment. Levi’s heart sank as he saw her enormous, bikini-clad body fill the space beyond the window. The sunlight streaming in made her skin glow, her figure towering and impossibly powerful. She paused, her hands on her hips, her eyes glinting mischievously as she peered into the box.

Her lips curled into a playful grin as she spoke. “You know what, little bro? I changed my mind.” Her voice boomed, every syllable resonating with excitement. “This… this is just too tempting.”

Levi’s blood ran cold as he backed away instinctively, his tiny legs stumbling over the soft fibers of the carpet. She leaned down again, her massive face filling the window. Her gaze swept over the apartment before she tapped the button once more, causing the tiny home to slide out of the shrinkbox with a shuddering lurch.

Her colossal hand moved closer, her eyes sparkling with delight. “Let’s make this fun,” she giggled, her voice dripping with amusement. She brought her index finger to her lips, wetting it with an exaggerated flourish, her massive tongue sweeping over the pad of her finger as she grinned.

“Hold still, little crumb,” she teased, her voice a mock whisper, though to him it was deafening.

Before Levi could even think to run, her wet finger descended into the apartment like a meteor. The saliva glistened ominously as the massive digit crashed through the pink carpet fibers toward him. He screamed, but the sound was swallowed by her presence as the sticky pad of her finger pressed against him with horrifying ease. The wet surface clung to his body, pulling him free from the carpet and lifting him skyward.

“Ahhh!” Levi’s screams tore from his throat as the world around him blurred. The force of being lifted so quickly made him nauseous, and when she finally stopped moving, he dangled helplessly in front of her massive, grinning face. Her eyes locked onto him, and her laughter rumbled like a thunderstorm.

“Oh my god, it worked!” Luna squealed, her delight washing over him like a physical force. “You’re actually sticking to my finger! You’re like a little piece of crumb!” She tilted her head, marveling at the speck-sized form of her brother. “No way… Just moments ago, you were almost as tall as me. And now look at you.” Her grin widened as she leaned in, her massive eyes narrowing as she squinted to make out his tiny, trembling figure.

Levi screamed again, his voice hoarse, but he knew she couldn’t hear him. She let out a laugh, the sound booming around him like cannon fire. “What’s that, bro? Are you screaming? I can’t even hear you!” She stuck out her tongue playfully, wiggling it at him. “Well, this probably won’t give you an erection,” she teased with a giggle, “but this is still fun, right?”

Her tone turned mockingly thoughtful as she inspected him closer. “Hmmm… What should I do with little crumbs like you?” She tapped her chin dramatically with her free hand, then gasped in mock surprise. “Oh! I know!”

Levi’s blood froze as her lips parted, revealing the yawning cavern of her mouth. Her warm breath rolled over him, humid and sweet from whatever she had eaten earlier. Her teeth gleamed like polished towers, and her massive, pink tongue undulated behind them like a creature of its own. His mind reeled with terror.

“No! No, Luna, stop! Please!” he screamed, his voice breaking, but she didn’t—or couldn’t—hear him.

Her grin turned wicked as she tilted her finger, pressing him against the tip of her tongue. He was immediately overwhelmed by the wet, sticky surface, the humid heat wrapping around him like a suffocating blanket. She smeared him across her outstretched tongue, her saliva clinging to his tiny form as she giggled.

The sound of her laughter was deafening, echoing all around him as her tongue shifted and wiggled beneath him. For a horrifying moment, she held him there, letting him feel the undulating terrain of her massive tongue. It rippled and flexed, the sticky surface pulling at him with each movement. He tried to push himself up, to escape, but it was useless. The sheer scale of her tongue compared to his body made any attempt at resistance laughable.

He begged, his tiny voice hoarse and broken. “Luna! Stop! Please!” But the only response was her giggle, vibrating through her tongue and into his body.

Then, just as he thought he might lose himself to the overwhelming wetness and heat, her massive finger reappeared, scraping him off her tongue with a gentle flick. He was lifted back into the air, still drenched in her saliva, and dangled in front of her face once more. Her eyes sparkled with amusement as she inspected him, her grin impossibly wide.

“Wow,” she said, her voice dripping with playful malice. “That was fun! You tasted pretty good, bro.” She laughed, the sound shaking him to his core. “I mean, I might have to keep you this size for a while… You’re just so tiny! I can do whatever I want with you.”

Her words echoed in his mind as she held him there, her laughter rolling over him like waves of humiliation.

“This,” she said with a wicked smirk, “is going to be so much fun.”
