Shiori sat on the edge of the bed, knees pressed tightly together, staring at her delicate hands. The room felt too small, too familiar, and completely wrong. Her long black hair kept falling over her shoulders, tickling the sensitive skin of her chest. Every small movement made her heavy breasts shift and sway, a constant reminder that this body wasn't hers.
What the hell am I supposed to do now? If I walk outside like this… everyone will stare. The guys from class will look at me like some kind of prize. Miura and the others… they'll either laugh or treat me like I'm one of them. And Hina… what would she think if the fat guy she pitied suddenly showed up as this?
Her new voice was soft even in her own head. She tried speaking quietly.
"I can't go to school. Not today. Not ever, maybe."
The words came out high and melodic. She flinched at the sound.
A voice called from downstairs, clear and familiar.
"Shiori! You're going to be late for school if you don't hurry!"
Shiori froze. Mom? She called me Shiori? Not Tanaka?
Her heart hammered against her ribs, making her breasts bounce slightly with each beat. She stood up slowly, testing her balance. Her hips felt wider, her center of gravity completely different. Every step sent a soft jiggle through her chest and rear. She tugged at the torn hem of the oversized t-shirt, trying to pull it lower, but it barely covered the bottom curve of her ass.
This can't be real. Maybe she just misspoke.
She crept to the door and opened it a crack, then padded downstairs barefoot, one hand on the railing for support. Her thighs rubbed together with every step, smooth and warm.
In the kitchen, her mother was packing a lunchbox, humming softly. She looked up when Shiori appeared and immediately frowned.
"Shiori, what on earth are you wearing? That looks like one of your father's old shirts, and it's torn! Did you sleep in that? You know better than to go around the house looking so sloppy."
Shiori stood there, mouth slightly open. Her mother's eyes held no confusion, no shock — just mild scolding, the way she always looked at her daughter when she was running late.
"Uh… sorry, Mom," Shiori said hesitantly. The words felt strange coming from her new throat.
Her mother sighed and set the lunchbox down.
"Honestly, you've been acting odd lately. Hurry up and change into your uniform. Breakfast is almost ready."
Uniform? My uniform? Tanaka's uniform is still upstairs in the closet… or is it?
Shiori swallowed hard. "Mom… do you remember anyone named Tanaka? Hiroshi Tanaka? From my class?"
Her mother tilted her head, confused. "Tanaka? No, I don't think so. Is he a new transfer student? Why?"
"Nothing… never mind." Shiori's stomach dropped. He's gone. Completely gone. No one remembers the fat kid who got bullied every day. It's like I never existed as him.
The realization hit like cold water. Hina's kind smile, the hallway laughs, the umbrella in the puddle — all of it belonged to a person who no longer existed in anyone's memory.
Her mother noticed her dazed expression. "Are you feeling alright, sweetheart? You look pale."
Shiori quickly shook her head, long hair swaying. "Actually… I'm not feeling well today. My stomach hurts a bit. Can I stay home? Just for today."
Her mother studied her for a moment, then nodded. "Alright, but only because it's rare for you to ask. Rest up and drink some tea. I'll call the school. Your father already left for work."
"Thanks, Mom."
Shiori turned and hurried back upstairs before her mother could ask more questions. Her heart was racing again. I bought myself one day. One day to figure this out before I have to face the world as… this.
Back in the room, she opened the closet door.
Tanaka's old clothes were gone. Instead, rows of girls' outfits hung neatly: school uniforms with pleated skirts, blouses, casual dresses, and drawers filled with bras and panties in soft colors. Everything looked like it would fit her new proportions perfectly.
She pulled out a simple white blouse and a knee-length skirt, then hesitated. How do girls even put these on?
First came the bra. She fumbled with the hooks behind her back for several minutes, twisting her arms awkwardly. When she finally managed to clasp it, the cups felt tight, lifting and pressing her massive breasts together into deep cleavage. The sensation of fabric against her nipples made them harden instantly.
Too sensitive… this is ridiculous.
The blouse was next. Buttoning it over her chest was a struggle; the fabric stretched across her bust, the buttons straining. The skirt sat low on her wide hips, the hem swishing against her thick thighs. She looked at herself in the mirror again and blushed furiously. Even in normal clothes, she looked stunning — and far too noticeable.
If I go out like this, everyone will stare. I'll humiliate myself in five seconds.
A sudden pressure built in her lower belly. She needed to pee.
Shiori hesitated at the bathroom door, then stepped inside and locked it. She lifted the skirt, pulled down the simple white panties, and sat on the toilet. The position felt completely wrong. Nothing happened at first. She had to consciously relax muscles she didn't understand.
When the stream finally started, it was different — warmer, softer, coming from a place that sent strange tingles up her spine. She finished quickly, wiped carefully, and stood up, legs shaky.
This is so weird. Everything feels… exposed.
By the time she washed her hands, her body felt hotter than before. A faint ache had settled between her legs, and her skin prickled under the clothes. The shower seemed like a good idea — something to cool down and wash away the morning's confusion.
She stripped quickly, avoiding looking at herself too long, and stepped under the warm spray.
Water cascaded over her shoulders, running down the heavy curves of her breasts. Her nipples tightened immediately from the temperature change. She gasped softly.
They're so big… and sensitive.
Her hands moved almost on their own at first — just washing. She cupped her breasts, feeling their weight, the soft flesh overflowing her palms. Her thumbs brushed the stiff peaks and a spark of pleasure shot straight down to her core.
"Ah…"
The sound escaped before she could stop it. Her voice sounded breathy and feminine even to her own ears.
No. I'm still me. Tanaka. This is just… temporary. I have to stay in control.
But her body didn't listen. One hand slid lower, over the flat stomach and the dramatic flare of her hips, then between her thighs. The smooth, hairless slit was already slick from more than just water. Her fingers brushed the sensitive folds and her knees nearly buckled.
Holy shit… it feels nothing like before.
She leaned against the tiled wall, breathing faster. Tentative circles with her fingertips sent waves of heat through her. The pleasure built quickly, unfamiliar and intense. Her free hand kneaded one breast, rolling the nipple between her fingers while the other hand pressed harder against her clit.
This is wrong… but it feels so good. I can't stop.
Her hips rocked involuntarily, chasing the sensation. The water pounded against her skin, mixing with the growing wetness between her legs. Soft moans filled the bathroom as she explored deeper, sliding one finger inside herself. The tightness, the warmth, the way her inner walls clenched — it was overwhelming.
Tanaka… you're touching a girl's pussy right now. Your own pussy.
The thought only made the heat spike higher.
Her movements grew faster, more desperate.
Pleasure coiled tight in her belly, spreading through her heavy breasts and down her trembling thighs.
Her teeth sank into her lip, and her eyes fluttered shut, the peak of pleasure drawing near.
"I… I can't…"
Her body, however, had other ideas. The orgasm hit her with a force that was both unexpected and overwhelming.
Her legs shook, a cry escaping her throat as waves of pleasure pulsed through her core. Her fingers kept moving through it, drawing it out until she was gasping, breasts heaving with each breath.
When it finally faded, she slid down the wall slightly, water still raining over her flushed skin.
What… what did I just do?
Shiori stared at her hand, then at the mirror fogged with steam. The beautiful girl looking back had messy wet hair, swollen lips, and eyes still hazy with afterglow.
She whispered softly, voice trembling.
"…I need more time."
