The air in the building was thick, almost oppressive, though none of the three women had noticed it at first. Sarah leaned against the counter, her hand instinctively resting on her still-flat stomach. The faintest hint of nausea tickled the back of her throat, a reminder of the tiny life growing inside her. She adjusted her dark blue long sleeve shirt, tugging at the fabric as if it might ease the discomfort. Across the room, Rose and Jane were bent over their workstations, their focus unwavering—until it wasn’t.Rose was the first to break the silence. She straightened suddenly, her breath catching in her throat. “Ugh,” she groaned, clutching her stomach. Her red tank top rode up slightly as she doubled over, revealing a sliver of her pale midriff. “What the hell is that? It feels like—like heartburn, but so much worse.” She belched loudly, her cheeks flushing with embarrassment even as she winced in pain.Jane glanced up from her workstation, her brow furrowing. “You too? I’ve been feeling weird for the last few minutes.” She rubbed her own bloated belly, the fabric of her green tank top stretching taut over her abdomen. “It’s like… I don’t know, like something’s churning in there.” She let out a small burp, her face screwing up in discomfort. “God, this is gross.”Sarah frowned, pushing herself away from the counter. “Are you two okay? You’re not—” Her words died in her throat as she caught sight of Rose’s arms. The skin was… changing. A fine layer of fur was sprouting across her forearms, the dark hairs thickening before Sarah’s eyes. “Rose, what’s happening to you?”Rose looked down, her eyes widening in horror. “What the—?” Her voice cracked as she held her arms out in front of her, staring at the fur that was now spreading up to her shoulders. Her fingers twitched, the nails elongating into tiny claws. “No, no, no, this can’t be real!”Jane let out a strangled cry, drawing Sarah’s attention. She was clutching her own arms, her breath coming in shallow gasps. “It’s happening to me too!” she shrieked, her voice rising in panic. Her once-smooth skin was now covered in a patchy layer of fur, the green fabric of her tank top straining against her expanding midsection. Her jeans slipped lower on her hips, the waistband unable to contain her bloated belly. “Sarah, what is this?”Sarah took a step back, her heart pounding in her chest. “What’s going on…?” Her hands trembled as she watched her friends’ transformations unfold. Rose’s face was elongating, her nose and mouth melding into a snout. Her red tank top slipped from her shoulders, pooling around her feet as her body began to shrink. Jane followed suit, her green tank top and jeans collapsing into a heap on the floor. Within moments, two small mice were scurrying about, their tiny bodies darting between the discarded clothes.Sarah stared in disbelief, her stomach churning with a mix of fear and revulsion. “Oh my God,” she whispered, her voice barely audible. She turned on her heel, her black pants swishing as she hurried toward the door. “I need to get help. I need—”Her words were cut off by a sudden wave of nausea, more intense than any morning sickness she’d felt before. She stumbled, her legs wobbling beneath her as she clutched her stomach. A sharp, stabbing pain radiated through her abdomen, making her gasp. “No, no, not now,” she muttered, her voice shaky. Her breath came in short, shallow gasps, each one feeling like a struggle against the weight pressing down on her chest. The heat in the room was unbearable now, like an invisible fire wrapping around her body. She tugged at the collar of her dark blue shirt, desperate for relief, but it wasn’t enough. Frantically, she grabbed the hem of her long sleeve shirt and yanked it over her head, tossing it aside. Cool air brushed against her exposed skin, but it didn’t help much. Her white bra clung to her damp skin, the soft swell of her belly glistening with a thin sheen of sweat. She looked down, her eyes widening as she noticed the faint shimmer of fur beginning to sprout along her arms and chest. It was thin at first, almost imperceptible, but it was there—real. She reached out to touch it, her fingers trembling as they brushed against the soft, growing layer of hair. “What the hell is happening to me?” she whispered, her voice breaking. Her stomach churned again, and she belched loudly, the sound echoing in the empty room. A sour taste filled her mouth, and she winced, pressing a hand to her chest as the heartburn flared up. This can’t be real, she thought, her mind racing. She scratched at her armpits, the skin there already prickling with the rapid growth of fur. It spread quickly, crawling up her arms and down her sides, until her entire torso was covered in a fine, soft layer. Panic set in as she felt her body begin to shift, her bones creaking and reshaping beneath her skin. Her hands went to her face, tracing the changes as her nose and mouth started to elongate, forming the beginnings of a snout. “No, no, please—” she choked out, her voice muffled and distorted by the transformation. She looked down at her legs, her black pants now loose and sagging as her body began to shrink. Her feet felt strange, her toes curling and shrinking into tiny paws. She tried to scream, but all that came out was a strangled whimper. Her legs gave out beneath her, and she collapsed to the floor, her body shrinking rapidly. The world around her seemed to grow larger, the ceiling stretching impossibly high above her. Her white bra slipped off, joining the pile of her discarded clothes on the floor. She looked down at her tiny body, now completely covered in soft fur, her paws trembling as she tried to make sense of what had happened. Her heart raced, thudding in her chest like a drum. She tried to speak, to call for help, but all that came out was a series of high-pitched squeaks. The room was silent except for the sound of her own frantic breaths—or what was left of them. She was a mouse. The realization hit her like a freight train, her tiny body trembling with fear and disbelief. Across the room, she could see Rose and Jane, their small, furry forms darting between the piles of clothes. They were mice too. And now, so was she.“What the hell is happening to me?” she gasped, her voice trembling. She scratched at her armpits, the fur there thickening with each passing second. Her hands moved to her face, her fingers brushing against the beginnings of a snout. “No, no, please—”Her legs gave out beneath her, and she collapsed to the floor, her body shrinking rapidly. The last thing she saw before her vision blurred was the pile of her clothes, the black pants and dark blue shirt crumpled on the floor beside her. And then everything went dark.When she opened her eyes, the world was different. The room was enormous, the ceiling stretching impossibly high above her. She looked down at her body, her tiny paws trembling as she tried to make sense of what had happened. She was a mouse.From across the room, Rose and Jane scurried toward her, their tiny eyes wide with fear. Sarah’s heart raced as she tried to speak, but all that came out was a series of high-pitched squeaks. She turned toward the door, her instincts screaming at her to run, to escape, to find help. But the door was impossibly far away now, and her tiny legs wouldn’t carry her fast enough.The three mice huddled together, their bodies trembling with fear and confusion. The building was silent now, the only sound the soft rustling of their fur against the cold, hard floor. And then, from the shadows, something moved.Sarah’s tiny heart leaped into her throat as a pair of glowing eyes appeared in the darkness. She tried to squeak a warning to Rose and Jane, but the figure was already moving, its approach swift and silent. The last thing she saw before the darkness swallowed her whole was the glint of sharp teeth, and the faintest hint of a smile.

In a seemingly ordinary building, three women—Rose, Jane, and Sarah, who is one month pregnant—are unaware that they are being exposed to a mysterious mouse transformation serum.

The women begin to experience strange symptoms, including bloating, heartburn, and fur growth, leading to their transformation into mice.

The transformation is sudden and horrifying, as they watch each other shrink and change, their clothes piling up on the floor.

Sarah, initially unharmed, rushes to get help but is quickly overcome by the same symptoms, transforming into a mouse just as her friends did.

The three mice, now vulnerable and scared, huddle together, unaware of the danger lurking in the shadows, ready to pounce.
