Author's Chapter Notes:

Wayne, getting frustrated at the results of his growth ray, gives it one more test run in preparation to sell the tech to the government. Meanwhile, a little mouse girl living in his walls accidently falls into the beam causing her to slowly grow. 

Can Wayne fix things or will our mouse girl grow too big to contain?

For an idea of what I was going for in terms of our mouse girl, here are two examples.

Wayne Krieger stood in his garage-turned-lab, staring at a suspiciously shriveled red delicious apple clamped to a rotating metal pedestal.

"Grow, damn you!" he muttered, jabbing at the buttons on his console. The beam sputtered, buzzing like a mosquito with an attitude problem. The apple remained firmly un-impressive. He sighed and rubbed his temples.

Ten years in defense R&D, and now he was an independent inventor trying to make a name with a "portable growth accelerator." He had grand visions: crops feeding millions, rebuilding disaster zones, and—if he played the politics right—maybe a contract with DARPA.

Instead, he had a stubborn apple and a garage that smelled faintly of singed plastic.

His phone rang. He didn't recognize the number but answered anyway. “Wayne. Talk to me.”

“Wayne! It’s Susan from NSF review. We’re still waiting on your test video. If you want funding, we need proof of something besides blueprints and theory.”

“Yeah, yeah, I’m working on it. I’m running tests right now. Just... hit a minor snag.” He winced as he glanced back at the apple, still smugly apple-sized.

Above him, balancing along a thin wooden support beam near the ceiling, a tiny figure watched Wayne with wide, curious eyes. Nattie—three inches tall, not counting her twitchy brown mouse ears—tiptoed silently along the railing, marveling at the weird human tech below.

She’d lived in the walls for months, ever since Wayne moved in. And while other hybrids in her family warned her never to get close to “the big ones,” Nattie had other ideas. She wanted adventure. She wanted romance. And maybe—just maybe—she wanted to be with someone taller than a tube of toothpaste.

Today, curiosity got the better of her.

As Wayne paced with the phone, gesturing wildly at the apple, Nattie leaned forward to get a better look at the strange glowing dish on the metal console. Her foot slipped.

“Shit—!” she squeaked as she tumbled from the beam.

Wayne turned at the sound, just in time to see a tiny blur falling through the beam’s path. The ray fired in a crackling stutter—then shut off with a loud pop.

He blinked. “What the hell—?”

On the floor, something was moving.

It was a girl. A…very naked one.

Small—smaller than a Barbie doll—but definitely growing.

“Uh…”

The phone slipped from his hand and clattered to the floor.

The girl groaned, rubbing her head. Her mouse ears twitched. “Ugh… I think I broke something…” She looked up at him, her eyes enormous and blue. “Whoa. You’re huge.

Wayne took a step back. “What. The actual. Fuck.”

She stood up, clearly dazed—but very clearly expanding by the second. Her arms flailed slightly as she regained balance, and her proportions shifted from toy-sized to more like a ventriloquist dummy. Then toddler-sized. Then... unsettlingly lifelike.

Wayne’s brain struggled to reboot.

“Okay, okay, okay.,b ” he muttered, hands on his head. “Think. THINK. Tiny naked mouse girl. Not hallucinating. Not drunk. Definitely just hit with the beam. Shit!”

Nattie looked down at herself. Her tail flicked, and her chest—now showing  a modest swell. “Hey! I’m growing!”

“No shit, Sherlock!”

She grinned, unfazed. “You sound grumpy for someone who just gave a girl a glow-up.”

“You just fell into my prototype growth ray. I was trying to make an apple into a watermelon, not play God with pint-sized fantasy girls!”

“Fantasy girl?” she said, cocking her head. “That’s flattering. Is that a compliment, or do humans always yell at women like that?”

Wayne pointed a shaky finger. “You... need to stop growing. NOW.”

She was already up to his waist.

“I don’t know how to stop it!” he barked, spinning back to the console. “That was the test beam, not the calibrated emitter! You weren’t even supposed to be in here! What the hell are you anyway? Where did you come from?!”

Nattie shrugged, inspecting her now-well-formed legs. “I’ve been living in your wall. You talk in your sleep, by the way. A lot. About ‘enhanced cellulose transference.’ Super sexy.”

Wayne's eye twitched. “This is not happening. This is some kind of hormone-deprived fever dream.”

But the now five-foot-two naked woman with a mouse tail disagreed.

“So what happens when I get... you know. Too big?” she asked, stretching her arms. “Do I blow up? Hulk out? Crush your house?”

Wayne blinked at her, distracted by how her curves were rapidly outpacing the moral part of his brain.

He cleared his throat. “Look, we’re going to figure this out. I’ll reverse the polarity or... bounce a signal through the flux coils. Just stop growing!”

She gave a playful smile. “Make me, mister scientist.”

He groaned, tugging at his hair. “This is so not what I had in mind for government testing.”

Wayne scrambled to his console, fingers flying across the keys in a panic. Numbers flickered, but none of them looked promising. No reverse sequence, no cooldown protocol, just a cheerful blinking message: "Energy Transfer: Successful!"

“Oh, it worked, alright,” he muttered, glancing behind him.

Nattie was now about five-foot-seven, standing comfortably on two bare feet, her tan tail flicking lazily. Her ears twitched as she examined her new body like a kid with a birthday gift—and no shame whatsoever about her lack of clothes.

“You, uh… you wanna maybe put on a towel or something?” Wayne asked, trying very hard to make eye contact and not look at the shapely, softly glowing woman who'd once been the size of a lighter.

Nattie raised an eyebrow. “Why? You weren’t shy about walking around naked that time with the pizza and the socks.”

Wayne squinted. “Wait, what?”

She grinned. “I’ve been living in your wall, genius. You get a lot of junk mail, by the way. Half of it says ‘Wayne Krieger’ in all caps. The rest just says ‘Final Notice’.”

Wayne's jaw dropped. “You’ve been watching me?!”

She shrugged. “I got bored. You mumble tech jargon in your sleep and leave the fridge open when you're drunk. I figured, if I was gonna risk living near a human, might as well be one with decent hair and weird gadgets.”

He pointed at her. “That is so invasive!”

She smiled sweetly. “You left your calendar open once. February twenty-sixth—'experimental self-dating ray.' Real subtle.”

“Okay, okay!” he barked, face going red. “You know my name, fine. Who the hell are you?”

She took a step closer, now only a few inches shorter than him. “Name’s Nattie.”

He blinked. “That’s it? Just... Nattie?”

She tilted her head. “What, you want a last name too? I don’t have a credit score.”

Wayne gave a half-laugh, half-snort. “Of course you don’t. You’re a... a three-inch hybrid wall-mouse girl who just crash-landed into my growth ray!”

She gave a mock bow. “Now five-foot-nine or something. And counting. You're welcome.”

A low hum pulsed from the console. The beam was still active in passive mode, pulsing residual energy into the air. Nattie’s fingers twitched. She wobbled slightly.

“Okay.” she said, blinking. “That one made my nipples tingle.”

Oh come on! Wayne shouted. “Do you have any shame?”

“Do you have any pants that aren’t cargo shorts?”

He glared. She winked.

The room was quiet a moment, tension crackling in the air—part electromagnetic, part something else.

Then she offered a hand. “So. Officially: Nattie. Former three-incher. New to your lab. Grew up dreaming about meeting a guy like you... just, you know, not so screamy.”

He stared at her, then hesitantly shook her hand. Her skin was warm. Her grip? Firm. She was now at eye level.

“Wayne Krieger.” he said, trying not to sound impressed. “Inventor, realist, and future victim of some very weird therapy.”

She smiled. “Nice to finally meet you, Wayne.”

Then came another pulse from the machine.

Wayne looked her up and down. “You’re still growing.”

Nattie looked down at herself—her chest was a bit fuller, her legs a little longer. “Sure looks like it.”

Wayne ran a hand down his face. “Of course you are.”

Wayne’s eyes darted to the readout. The residual charge from the growth ray was continuing to compound—feeding off some kind of feedback loop. She wasn’t just growing… she was accelerating.

“Shit. Shitshitshit!” he hissed.

“Something wrong, big guy?” Nattie asked, brushing a lock of silvery-brown hair behind one ear. She stretched casually, now slightly taller than she’d been a few seconds ago. “You’ve got that whole ‘mad scientist on a timer’ look.”

Wayne muttered, “You’re going to be taller than me in twenty minutes.”

She blinked. “Seriously?”

He pointed at her head, which was inching higher, slowly overtaking his own. “Yeah. And in a couple of hours, you're going to be—”

“A giantess?” she said, voice gleeful. “Oh my god. You’re telling me I’m gonna be, like, building-sized?”

He spun on his heel and bolted for the laundry pile near the back wall. “Okay, no. We’re not leaning into your weird size-fantasy thing right now. We’re focusing on not turning my garage into a crater.”

“Oh c’mon!” she said, watching him dig. “You invent agrowth ray, and you’re surprised this is turning sexy?”

“Here.” he grumbled, tossing a faded graphic tee at her. “Put this on. Before you give me an aneurysm.”

Nattie held it up. It had a pixelated ‘80s robot on it and smelled faintly of solder and Axe body spray.

“It’s gonna be tight!” she said, smirking.

“It’s temporary!” he snapped. “I need like, twenty minutes to recalibrate the beam, isolate the charge buildup in your cells, and—”

RRRRRIP.

She’d pulled the shirt on. Well… half on. It stretched across her chest like spandex over a beach ball. The bottom hem didn’t even reach her belly button, and the collar was clinging on for dear life.

“—annnnnd you’re gonna Hulk out of it in ten.” Wayne finished, massaging his temples.

She looked down and gave an approving nod. “Honestly? Not bad for wallgirl chic. You’re not a bad dresser when you're not wearing socks with sandals.”

He ignored the insult and shoved a cable into the console.

“You’ve got about two hours before you're the size of a strip mall.” he muttered. “I need to reverse this before you hit kaiju modeand get stuck in the stratosphere.”

Nattie raised an eyebrow. “And what if I don’t want to stop?”

He froze mid-keystroke. “Excuse me?”

She grinned. “I’m taller. Stronger. Hotter than I’ve ever been. Every second feels amazing. I could literally pick up a truck in like... half a day. Maybe crush it between my thighs.”

Wayne stared. Then blinked.

Then looked away. “That’s not—don’t say that. That’s not fair.”

“You’re blushing.” she teased.

“I’m panicking.”

“You can panic and be aroused. Multitask, Wayne.”

He slammed the keyboard. “Okay! That’s enough sexual tension while I'm trying to prevent a skyscraper-sized mouse woman from walking through my roof!”

Nattie giggled and leaned down, putting her face close to his. “You better hurry, Wayne. Tick-tock. I'm not getting any smaller.”

And she wasn’t. Her frame was visibly stretching again—shoulders broadening, hips thickening, and the shirt's seams audibly straining.

Wayne stared at the loading bar on his console.

18%.

“Oh, you’ve gotta be kidding me…”

Wayne sat back from the console, chest rising and falling as the processors whirred and the stabilizer finished its recalibration sweep. The room had gone strangely quiet.

Except for her breathing and ever-growing presence.

Nattie was leaning against the workbench now, one hip casually braced as she watched him. She was taller than him by a few inches, the shredded shirt barely clinging to her upper body. Her bare skin caught the lab’s fluorescent light, golden and smooth—tan, he realized. Not covered in fur. Not rodent-like. Just... her.

Despite the ears and tail, she looked more human than hybrid.

Her body wasn’t exaggerated or cartoonish. She was lithe, athletic, and real. And the way she looked at him—curious, warm, a little nervous—it didn’t match the teasing she’d been throwing around.

Wayne ran a hand over his face. “You said you were in the walls. All this time.”

Nattie nodded, tail swishing slowly. “Since the week you moved in.”

“I thought I had raccoons.”

“Nope.” she said, tapping her temple. “Just me. Quiet as a... well, yeah.”

He gave a soft, tired laugh.

“You saw Tessa leave?” he asked.

Her expression changed—softer, almost guilty.

“I heard her yelling. She slammed the door so hard it made my shelf collapse.” she said, her voice quieter now. “You didn’t chase her. You just sat down and... sort of broke.”

Wayne nodded slowly. That night had felt like a hole punched in his chest.

“I wanted to do something.” Nattie continued. “Say something. But I was... this.” She held up her hands, miming her old size. “I was the size of a goddamn credit card with ears.”

He finally looked at her—really looked.

The mouse ears twitched faintly, half-curled in bashful instinct. The long tail curled around her leg like a ribbon. But her face? It was open. Human. Beautiful, even. And not just in a “science accident” kind of way.

“You thought I wouldn’t like you.” he said softly.

She nodded. “I mean, c’mon. You’re smart. You’re tall. You fix stuff. You have a jawline sharp enough to cut glass when you’re angry. Me? I had a soap dish for a bathtub.”

Wayne leaned against the bench opposite her, his panic temporarily muted by something heavier in his chest.

“And now?” he asked. “You think this changes things?”

She hesitated.

“I think...” Her voice cracked just a little. “I think I didn’t believe someone like you could see someone like me. Not when I was tiny. Not even now.”

Her lip quirked. “Even if I’m literally eye level with you and growing bigger every minute.”

He stepped closer, their bodies just inches apart.

“I see you.” he said, voice low. “I didn’t. But I do now.”

Nattie’s breath caught, and for once, she didn’t have something sassy to say.

Their eyes locked. Then—BRRZTT!—the console buzzed again.

Wayne jumped. “Shit! 91%! I’ve almost got the reversal cycle ready.”

Nattie exhaled and stepped back, giving him room.

“Then you better move fast, Wayne. Because in ten more minutes...”

She slowly straightened up to her full height—now a solid six-foot-five—and leaned down with a grin.

“I’m going to be too big to fit in your damn garage.”

Wayne's fingers hovered above the keyboard. As the progress hit 100%, he was just one keystroke away from initiating the reversal cycle. The cooldown script was ready. Energy matrix aligned. If he hit execute, she’d start shrinking within seconds.

But then he felt it—her hand, larger now, gently touch his forearm.

“Wait.” Nattie said softly.

He turned to look up at her—literally up. She was now nearly six-foot-eight, her bare feet planted firmly on the concrete floor, her long legs graceful, powerful. The light overhead flickered slightly as if her presence alone messed with the circuitry.

“Nattie…”

“Please.” she said, eyes wide and warm, not playful this time. “Just a little longer. I want to feel this. Just for a bit.”

Wayne hesitated. His engineer brain was screaming. She was unstable. The energy saturation was exponential. Every second she stayed like this, the risk increased.

But then she smiled—a little nervous, a little raw.

“I’ve never felt big before.” she said. “I’ve always been careful. Small. Hiding. Now the world finally feels... right. And I don’t want to lose that just yet.”

Wayne stared at her. Her words hit harder than he expected. He took a breath. Then lowered his hand from the keyboard.

“Alright.” he said quietly. “But not long.”

Nattie lit up like moonlight, the relief clear in her face. Before she could say anything, Wayne grabbed her hand—larger than his now, fingers warm and strong—and tugged gently.

“Come on.” he said, a smile tugging at his mouth. “You want space? Let’s get you some.”

They stepped out of the garage, the door creaking as it swung open behind them. The night was quiet, the stars hanging low over the dark stretch of dry earth and wild brush. His property sat on the edge of nowhere—just a mile of gravel road, a few old sheds, and enough trees to shield them from any nosy eyes.

Nattie stepped into the open air, barefoot in the cool grass, and took a slow, deep breath.

“Wow...” she whispered.

Wayne let go of her hand and watched her take it in.

The sky felt closer now. Or maybe she did. She stood there, nearly seven feet tall, a silhouette of strength and strange beauty against the night. Her tail flicked lazily behind her. Her hair moved in the breeze. And her shirt—what was left of it—flapped like a flag barely clinging to her shoulder.

“I feel like I could walk to the stars.” she said.

Wayne chuckled. “Try not to. I’m still working on the part where you don’t explode.”

She glanced at him. “So what’s it like?”

“What?”

“Seeing your tiny wall-girl crush grow into a goddess?”

He smirked. “Mostly terrifying.”

Nattie stepped closer, towering over him now, barefoot in the grass.

“But kinda hot?” she teased.

He rolled his eyes. “Maybe a little.”

She laughed—a full, joyful sound—and then turned her face to the sky again. For a moment, everything was still. Just her, standing larger than life, framed in the night like a dream made real. No walls. No fear. And for once, no shrinking from who she was.

The grass rustled under Nattie’s bare feet as she took slow steps through the clearing behind Wayne’s garage, the moonlight washing over her tan skin in silver tones. The night air was crisp, cool against the sweat rising on Wayne’s neck—not from the weather, but from the sight in front of him.

She was still growing.

It was subtle at first. Her legs stretching longer, her hips widening, her arms flexing with quiet strength. But then it began to surge. Every breath she took seemed to bring more mass, more height, more presence.

Wayne could feel it—like the hum of a massive engine just under the surface.

He looked up. She was already twice his height.

“Wayne,” she said, softly. Her voice was deeper now, velvet and thunder. “Is it too much?”

He shook his head slowly, trying to process the awe rising in his chest. “You’re... incredible.”

She smiled, a little bashful despite being literally a living monument now.

“It feels unreal,” she said. “Like I’m not just growing... I’m becoming. Something more.”

Wayne took a slow step toward her. Her enormous form loomed above him, her thighs thick and firm like pillars, her torso a graceful slope of strength and curve. The remains of the tattered shirt clung across one shoulder and down her chest, no longer modest—just symbolic.

His head barely reached her navel now.

Nattie looked down at him, her massive hand rising to brush her hair back. Even that small movement stirred a gust of air against his face.

“I can feel everything, Wayne. Every part of me... humming. Alive. I didn’t know what it meant to take up space until now.”

Then her voice dropped to a whisper—low, warm, intimate.

“And I still feel small when you look at me like that.”

Wayne’s heart pounded. She could’ve crushed a car now. Could’ve picked him up and cradled him like a doll.

But she looked at him like he still mattered. Like he still anchored her.

“You’re not small.” he said, stepping closer and resting a hand gently against her thigh. It was warm and smooth, the muscle underneath subtly tensing at his touch. “You’re... magnificent.”

She knelt slowly, the earth beneath her groaning faintly under her weight, until her enormous face hovered just above him, their eyes locking.

“Do you still see me?” she asked. “The girl in the wall?”

He reached up, brushing his hand along her cheek, careful but unafraid.

“I do. But now... I see all of you.”

She leaned forward, her massive hand curling protectively around his waist—not squeezing, just holding, with surprising tenderness.

Their foreheads nearly touched, despite the impossible size difference.

And then—another pulse rippled through her body. A deep thrum from within as her growth surged forward again. Her hand around Wayne thickened, fingers lengthening. Her eyes widened slightly, her breath hitching.

“I think it’s speeding up.” she whispered.

Wayne looked up.

She was swelling with every second now—rising higher again, her kneeling form still dwarfing him, her chest now above his head even crouched. Her body glowed faintly from within, alive with unstable energy. More than three times his height—and still growing.

He should’ve been afraid but truly he wasn’t.

Instead, he reached out and rested both hands on her now-gigantic palm, grounding her.

“You’re still you.” he said.

She stared at him, eyes glistening, full of feeling.

“And you’re still the only person who ever really saw me.”

The clearing was still, save for the low electric hum that radiated softly from Nattie’s skin, pulsing with every breath. She knelt above Wayne like a goddess made flesh, her body now impossibly vast—towering, curvaceous, and radiant beneath the stars.

Twenty-five feet tall, by his estimation. And somehow... she’d never looked more human.

He stood there, barely to her knees now, hands resting on the warm expanse of her palm, heart thudding with adrenaline, awe, and something else he hadn’t felt in a long time: connection.

Then she whispered, “Wayne...?”

He looked up into her enormous eyes—blue as ocean glass, filled with something fragile underneath the glow.

“I know this is crazy.” she said. “I know I’m huge and weird and this probably breaks every law of physics and dating etiquette but…”

She hesitated, then leaned in closer. Wayne didn’t move. He didn’t run. He didn’t speak.

She tilted her massive head, her lips parting slightly—full, soft, and trembling with uncertainty.

“I’ve wanted to do this for a long time.” she said. “Even when I was small. Even when I thought I never could.”

And then she kissed him. It should’ve been overwhelming to him but it felt….so natural.

She was enormous—her lips alone wider than his shoulders. But she moved carefully, delicately, the way someone might handle a soap bubble. Her mouth brushed against his with impossible gentleness, her warm breath surrounding him like a summer breeze. Her lower lip curved softly under his chin, and her upper lip rested above his nose. Yet somehow...

It felt right.

Wayne's eyes closed. It wasn’t a giant kiss. It wasn’t a fantasy or a freak accident. It was her. Nattie. The girl who knew his worst day. The girl who lived in the walls and still chose to see him at his most broken.

His arms rose instinctively, resting on the smooth curve of her lip as he leaned into her, returning the kiss as best he could.

To him, it wasn’t strange.

To him, it was like kissing someone who had always been there—just finally visible.

When they pulled apart, Nattie’s face hovered close, her lips curved in a half-smile, eyes searching his.

“You’re not scared of me.” she whispered.

“I’m scared of a lot of things.” he said. “But not you.”

She exhaled, her breath warm and sweet as it passed over him.

“I don’t want to shrink back yet.” she admitted. “Not if this is the first time I’ve really felt alive.”

Wayne reached up, touching her cheek with both hands.

“Then don’t.” he said. “Not yet.”

A pause passed between them—quiet, heavy with emotion, and possibility.

Then Nattie giggled, her voice like soft thunder. “You realize I could pick you up and carry you around like a teddy bear now, right?”

Wayne grinned. “If you do, I want pants and a seatbelt.”

She beamed, her enormous fingers gently curling around his waist once again, cradling him with more care than a human hand had ever held him before.

“I’ll be gentle.” she said, rising slowly to her full towering height, holding him close to her chest.

Wayne looked up at the stars—and realized he wasn’t grounded anymore. And for the first time in a long time... he didn’t mind.

==

Wayne couldn’t see the garage anymore.

He was nestled in the warm cradle of Nattie’s palm, her body stretching into the night sky like a living monument. She was glowing faintly now—not just from residual energy, but from something inside her. Confidence. Thrill. Want.

She stood tall—at least sixty feet by now—barefoot in the soft grass, hips cocked, her figure now larger than some houses, and still undeniably, beautifully her. Curvy, tan, and radiant. And smiling down at him like he was the most precious thing she’d ever held.

“This feels dangerous.” Wayne said, staring up at her from his position against her chest. The swell of her breast behind him rose like a warm wall, barely held back by what remained of the ruined shirt strap.

Nattie’s voice came low, teasing. “Oh, it is. But you're safe with me, little man.”

Her fingers shifted slightly, pressing Wayne just a bit closer to her chest. The heat of her skin radiated through his clothes. Her heartbeat thrummed beneath him like a steady drum, slow and strong.

“I think I’m getting addicted.” she whispered.

“To what?” he asked, voice low.

She licked her lips slowly, eyes half-lidded. “This. You. The way you look at me now. The way I feel. Every second I’m bigger, I feel more... alive. More me.

She curled her fingers around him tighter—not crushing, just holding. Possessive. Protective.

“I always wanted to be seen.” she said. “But now? I own the view.”

Her other hand came up, sliding down the curve of her hip, her body rolling subtly as she stretched. “And I’ve never felt this good.”

Wayne swallowed as he watched her move. Every shift of her body was a slow-motion earthquake, sensual and smooth. Her thighs were the size of tree trunks now, her breasts like hills, her hair swaying in the breeze like silk curtains.

And still... her eyes never left him.

She sat down carefully, lowering herself to the ground like a goddess descending from the heavens. Her legs stretched out for yards in either direction, and she placed Wayne on her smooth stomach, flat and firm under her tan skin.

He stumbled slightly as she let go, and she giggled—a low, deep sound that made his knees wobble.

“You okay there, tiny?” she asked.

Wayne glanced around, standing on her body like it was living terrain. “I’m either about to make history… or die very confused and aroused.”

She smirked, her voice purring. “Let’s aim for the first one.”

Nattie shifted again, her chest rising behind him like a gentle slope, her body warm and soft beneath his feet.

“I used to wonder what it’d be like.” she murmured. “If I were normal. Human-sized. If someone like you would even look at someone like me. But now...?”

She licked her lips again, slow and deliberate.

“Now I don’t want to be small.”

Wayne looked up into her face—massive, flushed, and smiling down at him.

“I don’t want you to be small either.” he said. “Not if this is who you really are.”

Her expression changed—softened, just slightly. Like his words hit somewhere deeper.

Then her hand came back down, fingers walking up her stomach until they reached him.

“You’re so warm.” she murmured, brushing him with one massive fingertip. “So... delicate.”

Her fingertip traced down his chest slowly. Wayne shivered. She leaned closer, her lips parting again—each one wide enough to kiss his entire torso.

“I want you.” she whispered, voice low and thick and filled with hunger. “Even if I have to grow into the sky to feel it all.”

Another pulse hit her body—deeper, more intense. She moaned softly as it rolled through her, visibly expanding again—now approaching sixty five feet, maybe more.

Wayne stumbled forward, gripping onto her skin for balance as the world shifted beneath him.

Her laughter rumbled under him. “Better hold on, little man…”

The final pulse rippled through Nattie’s body like a rolling wave of pleasure.

She gasped—low, drawn out—as her toes curled into the soft earth, fingers digging into the grass behind her. Her spine arched ever so slightly as the sensation washed over her. The hum, the pressure, the unstoppable more of it... finally eased.

And then, it was still. No more stretching limbs. No more dizzy rush of sudden height. Just heat. Power. And Wayne, standing tiny and warm on the curve of her stomach.

She exhaled slow, steady, and deep. The air from her lungs rolled over him like a sensual breeze.

“I think... that was it.” she whispered.

Wayne looked up at her—sixty-five feet tall, radiant in the moonlight, chest rising and falling like the sea. Her shirt had finally surrendered somewhere around the 40-foot mark, leaving nothing between her golden skin and the stars.

“You done breaking physics now?” he asked, smiling.

She smiled back, biting her bottom lip slightly. “Maybe just bending them.”

She sat up slowly, careful not to jostle him too much, her massive arms propping her up from behind as she looked down at him—eyes half-lidded, expression soft and hungry.

“You still want me?” she asked, voice a velvet purr. “Even like this?”

Wayne didn't hesitate. “Especially like this.”

Something in her face melted—walls that had once guarded a much smaller girl now crumbling completely.

“Then come here.” she whispered.

She reached down, scooping him up gently, her hands like a warm hammock around him. She brought him to her lips and pressed a soft kiss to his chest, her massive mouth warm and tender, lips parting slightly against him. He groaned, feeling the heat of her breath as it soaked through his clothes.

“You taste... so small.” she murmured, kissing him again—slower, lower.

Wayne gasped as she laid back in the grass, placing him carefully between the soft curves of her breasts, the valley warm and scented with her skin.

“Hold on to me.” she said, voice trembling with anticipation. “Let me feel you.”

He moved against her, pressing into the supple heat of her body as her hands traveled across her chest, gently pressing him into the curve of her breast. The rhythm of her breathing, the soft moans rising in her throat, the way her thighs flexed and squeezed against the dirt—it was all building now, thick with heat and tension.

Nattie bit her lip, stifling a deep, needy groan. Her fingers caressed her own body as she held him close, her every movement deliberate, sensual, confident. No more hiding. No more shrinking away.

She was power, size, want—and his.

“I used to dream of being this close to someone.” she whispered, “and now you’re all over me.”

Wayne could barely respond—half from the pleasure, half from the sheer awe of her. Every part of her body pulsed with energy, and he felt wrapped in it.

She arched slightly as her fingers slid lower, one hand cradling him to her chest while the other traveled teasingly beneath her hips.

Wayne looked up, breath ragged, watching the way her body moved—undulating, perfect, immense.

And Nattie? She just smiled, wild and beautiful, as she let herself go.

The night air was filled with moans, with whispers, with the sound of a giant girl finally—finally—letting herself be everything she ever wanted to be. And in the center of it all, nestled against her heart, Wayne held on.

==

The stars above were still and silent. The clearing smelled like grass, ozone, and something sweetly human.

Nattie lay on her back in the soft field, her towering frame glowing faintly in the night, chest rising and falling in the steady rhythm of deep, post-release calm. Her lips were parted slightly, still glistening from breathless moans. Her skin shimmered with a sheen of sweat, soft and golden in the moonlight.

She didn’t speak because she didn’t need to.

A tiny shape moved slowly up her body—Wayne, slick and tousled, climbing the gentle slope of her chest like a man scaling a sun-warmed hill. She felt his every motion: his weight, his warmth, the deliberate touch of someone who meant it.

When he finally reached the soft rise of her left breast, he sat down, legs spread across her skin and looked out at the vast field ahead—her body stretching out beneath him like a living landscape.

“You okay?” he asked, his voice gentle.

She gave a soft hum. “Mmm. Better than okay.”

Her giant fingers came up and rested beside him, the pads curling slightly for him to lean into. He did, nuzzling her fingertip with his shoulder before laying back comfortably against her.

The silence between them was the kind that didn’t need to be filled. Just the sound of breathing. Crickets. The occasional whisper of wind moving through her hair.

Eventually, she whispered, “I didn’t think anything like that could feel real.”

Wayne looked up at her. “The orgasm, or the connection?”

She gave a sleepy chuckle, her massive chest rumbling beneath him. “Both. But mostly you.”

His face softened.

“I know this is wild.” he said. “I mean—hell, you're like 65 feet tall and glowing and I’m... clinging to your boob like a sunbather.”

“Flatterer, little guy” she murmured.

“But when you shrink back.” he continued, brushing her skin with his hand, “none of this changes. You’re still you. I’m still me. We’re still us.”

Nattie blinked, her expression suddenly unsure. “You mean that?”

“Every word.”

“But what if I don’t want to shrink?” she asked quietly.

He paused. Then smirked. “Then I’ll invest in some climbing gear and a reinforced mattress.”

She smiled, eyes a little glassy.

Wayne leaned down and kissed her skin softly, just over her heart. “I don’t care how tall you are, Nattie. You were in my walls. You saw me at my worst. And somehow, you didn’t run. That means more than all of this.”

She exhaled slow, chest rising gently beneath him. “I thought being small meant I wasn’t worth seeing.”

“You were wrong.” he said, voice firm but kind. “And you never have to hide again.”

Her massive hand shifted slightly, her thumb brushing his side—affectionate, grounding.

“I think I could lay here forever.” she whispered.

“You’ve earned it.”

She closed her eyes, smiling.

And in that moment—no tech humming, no growth pulses, no size jokes—just the girl and the guy in the field under the stars, everything felt beautifully, impossibly normal.

They laid in the grass for what felt like hours, wrapped in silence and moonlight. Wayne rested against the gentle slope of Nattie’s chest, rising and falling beneath him like soft hills. Her giant fingers lay beside him, twitching faintly as she toyed with a loose strand of grass the size of a twig.

Finally, she spoke—low and thoughtful. “I should probably shrink back down.” she said.

Wayne turned his head to look up at her. “Yeah?”

She hesitated. “Yeah. I mean, I should. I really should.”

“But…” he prompted, smiling.

Nattie’s lips curled. “But I really like being this big.”

He chuckled. “I noticed.”

She tilted her head, staring up at the stars as if she were level with them. “When I was small, cats used to scare the hell out of me. Sleek little assassins. I had to tiptoe past their drool-slicked whiskers like a damn ninja every time I wanted a crumb.”

Wayne raised an eyebrow. “And now?”

She grinned. “Now I’m the top of the food chain.”

He laughed. “You want to stay big just to scare the neighborhood cats?”

“No.” she said, stretching out luxuriously. “I want to stay big... to casually scare them. Big difference.”

Wayne flopped dramatically across her collarbone. “That is the most Nattie thing I’ve ever heard.”

“I’m just saying.” she said, her voice mock-serious, “you haven’t lived until you’ve watched a tabby run for its life because it saw your ankle coming over the ridge.”

Wayne smiled, shaking his head. “You are definitely ridiculous.”

“Yup.” she said with pride. “And, temporarily, sixty-five feet of it.”

They both laughed—hers echoing across the trees like distant thunder, his muffled against her skin.

After the laughter faded, she exhaled slowly and went quiet again.

“But seriously.” she said, voice softer, “I don’t want this to mess with me. It’s tempting, you know? Being bigger than everything. Being noticed just because you exist. I could get used to that too fast.”

Wayne reached out, placing a hand over the soft, steady thump of her heart. “It didn’t change who you are.”

She looked down at him, her eyes bright and steady.

“No.” she said, “but it helped me see her.”

They sat with that for a moment. The truth of it. The rightness of it.

Then Nattie sighed dramatically.

“Alright. Let’s go hit your science junk and start the shrinking. Before I start using my foot to knock over birdhouses like dominoes.”

Wayne grinned and sat up. “You want me to carry you this time?”

She smirked. “When I’m small again, you’re the one getting carried.”

“Fair.”

Nattie gently cradled him in her hands, her touch tender and slow as she stood, casting a long, gentle shadow across the grass.

“Let’s go, little man.” she said, smiling. “Tomorrow’s got cats to traumatize.”

The moon had dipped lower in the sky by the time they made it back to the garage.

Wayne stood by the console again—his laptop propped open, the coils humming gently with reversed charge. The interface glowed blue instead of red now. Shrinking sequence, fully ready.

Nattie sat on the edge of the clearing just outside, her 65-foot form illuminated in soft halogen light spilling from the open garage door. She looked almost celestial now—half-goddess, half-girl-next-door, wearing nothing but the wind and a smile.

“So…” she said, fingers playing with a tree branch like a cocktail stirrer, “is this where you zap me back down to credit card size?”

Wayne chuckled, adjusting the settings. “Not all at once. The beam works best gradually. I can slow it to stop you at any point.”

Nattie grinned. “Oh good. I wouldn’t want to miss the part where you finally get a proper kiss.”

He glanced up from the screen, brow arching. “Proper, huh?”

She leaned down toward the garage, enormous and graceful, until her face filled the doorway like a rising moon. “One not interrupted by the fact that I could’ve accidentally inhaled you.”

Wayne flushed a little but smirked. “Fair point.”

He flicked the switch. The hum began—a gentle blue pulse flowing through the coils. Nattie’s body shimmered subtly. Shrinking didn’t come in jolts like growing had. This was smoother, calmer. She felt it first in her fingertips, a tingling ripple working its way down her arms, her legs shortening slowly, her body folding inward like time was reversing.

In seconds, she was thirty feet tall. Then twenty. Then twelve.

She stepped into the garage now, ducking carefully through the open ceiling panel that hadn't survived her earlier surge in size. Her movements were more fluid, grounded again.

At around six feet tall, the shrinking slowed.

Nattie blinked. “Are you—?”

But Wayne was already there. He stepped forward, took her face gently in his hands, and kissed her.

No towering limbs. No awkward angles. No lips the size of couch cushions.

Just her and him Equal height. Equal heat.

Their mouths moved together softly at first—tender, slow, like they were rediscovering each other in a way the chaos hadn’t allowed. Then it deepened—urgent, warm, teeth grazing lips, breath mingling. Her arms curled around his shoulders, and his hands slid to her waist.

For a moment, the garage vanished.

There was only that kiss. The kiss they’d both waited for—through the walls, through the madness, through the electricity and wonder and fear.

When they finally parted, Nattie rested her forehead against his, breathy and pink-cheeked.

“That.” she whispered, “was definitely worth the size detour.”

Wayne smirked, brushing a lock of hair from her cheek. “Told you the tech was good for something.”

Then he glanced at the console, where the shrinking sequence was still active, now gently pulsing. “You ready to finish it?”

Nattie nodded, reluctantly stepping back.

“Yeah.” she said. “Let’s bring me home.”

The light shimmered again, and she began to dwindle.

Five feet. Three feet. Two feet. Her limbs pulled inward, eyes still fixed on him. Her tan skin caught the light until she was down to the size of a soda can... then a playing card.

Finally, she stood on the table—three inches tall. Mouse ears twitching. Tail still curled around one leg. Still unmistakably Nattie.

She looked up at him, hands on hips, completely unbothered by her scale.

“Well.” she said, voice small but proud, “guess I’m back to being apartment décor.”

Wayne crouched down to her level, smiling.

“No.” he said softly. “You’re the girl I kissed like the world was ending.”

She blushed just enough to glow.

“And.” he added, scooping her gently into his palm, “the one I’m never letting disappear again.”

She leaned into his touch, resting against his thumb like it was a warm wall.

“Good.” she said. “Because no matter how small I get, I’m always gonna take up space in your world.”

                                                                              One week later


The garage was back in one piece—mostly.

The roof still had a suspicious new patch of sheet metal, and one of the lab benches was permanently warped from the weight of a former giant mouse girl. But the consoles were lit, humming softly, and Wayne was back at work. Sort of.

He stood at his workbench, typing in a few updates to the ray’s calibration sequence, eyes focused but relaxed. No military-grade pitch decks this time. No sales plans. Just careful math. Careful design.

And perched on his shoulder, lounging like a queen on her throne, was a three-inch-tall mouse girl in tiny yoga pants, a fitted black T-shirt with a cartoon atom on it, and the cutest little shrunken white lab coat stitched with her name on the breast: Dr. N. (Mostly Qualified). On her feet? Tiny gray flats with a hint of sparkle.

“Hey.” she said, nudging his neck with her elbow, “are you even listening to me or are you getting turned on by your code again?”

Wayne smirked. “Both. You’re not exactly making it easy.”

She sat up straighter, tail flicking behind her with practiced elegance. “Well good. If I’m not at least half the distraction in this garage, I’m not doing my job.”

He tapped in a final line of code, then leaned back with a satisfied sigh. “There. Growth ray’s running like butter.”

Nattie stretched, arms overhead, the fabric of her tiny lab coat tugging with the motion. “You gonna sell it?”

Wayne glanced at her and smiled. “Nah,” he said. “Not interested anymore.”

She blinked. “Really?”

“Really. Not after... everything. I think I’ve found my market.”

She beamed, clearly proud of herself. “Ohhh, so I’m a private beta now?”

“You’re the whole damn product line.”

Nattie laughed and gave him a tiny kiss on the cheek. He turned his head slightly and caught a faint brush of her lips near his jaw—so soft he might’ve missed it if he hadn’t been waiting for it.

After a beat, Wayne said, “Hey, this weekend…”

“Yeah?”

“I was thinking… maybe I grow you up to, you know... human size. Just for a day. We could go out. Dinner. Something real.”

Nattie blinked, startled, then lit up.

“Wait—like a date-date?”

Wayne nodded, sheepish. “Yeah. I figure you deserve to be seen. In public. Not just... perched on my shoulder like a high-tech accessory.”

She squealed—a high-pitched, thrilled noise—and jumped up on his shoulder, bouncing slightly. “I can wear that black dress! The one I stitched from that napkin! And those pointy shoes I saw on that girl in town last week!”

Wayne raised an eyebrow. “You mean heels?”

“YES! Those! Oh my god, I can finally hear what they sound like on a wood floor! Click-click-click, like a boss lady with secrets.”

He chuckled. “You do realize everyone in town’s gonna stare, right? A five-foot-something mouse girl in heels might cause a small panic.”

She crossed her arms, expression suddenly sincere beneath her excitement. “Let them stare.”

Wayne looked at her. Nattie looked right back. “If I get to hold your hand, Wayne? It’s worth it.”

That silenced him. For once, the scientist had nothing clever to say.

He reached up, cupping her tiny body gently in his palm and lifting her off his shoulder. She curled easily into his hand like she belonged there—which, she did.

“Dinner it is.” he said softly.

“And maybe dancing?” she asked with a hopeful grin.

Wayne smiled. “Only if you don’t crush me with those pointy shoes.”

She gave a mock gasp. “Sir, I would never step on you.”

Then she smirked. “Unless you ask nicely.”

Chapter End Notes:

Depending on how this is received, I might do a follow-up in the future where it follows the two of them out on the town.
