Forced Feminization Crossdressing Story: Until Yuuta Becomes Yuuka
Yuuta used to know exactly who Akira was—his best friend, his teammate, the guy who choked on every sprint but never missed a shot. That certainty started cracking the day Akira walked into class wearing a skirt, and it hasn't stopped since. Now the whole school whispers about how "cute" Akira has become, boys are lining up for a confession, and Yuuta can't stop staring—can't even explain to himself why it bothers him so much.
Then he finds a torn newspaper clipping buried in the library stacks
Forced Feminization Crossdressing Story: Until Yuuta Becomes Yuuka - The Siren's Whisper — The Day I Choose Myself
The afternoon before summer break. The halls of Siren Academy carried a restless energy, a notch livelier than usual. With the long holiday starting tomorrow, students' voices rang out bright and their footsteps were light. The shoe lockers were packed—some kids tearing down club recruitment posters, others clustered in groups swapping contact info.
Yuuta waited a little apart from the commotion, leaning against the wall. He pushed up his angular-framed glasses. His fingertips were slightly damp.
(So I'm really doing this.)
Last night kept replaying in his head. Akira confessing in tears at the seaside park. Being dressed up by Mikoto and having his body changed by siren magic. Mikoto herself losing memories as the price of her magic.
And that kiss.
The taste of tears still lingering on his lips.
(That was my answer.)
Yuuta gripped a small blue hair ornament inside his uniform pocket. The one Akira had given him at the Mermaid sundries shop that day. He'd never been able to throw it away.
"Yuuta, were you waiting?"
He looked up at the voice.
Akira walked toward him from down the hall. Her brown hair fell in soft inward curls, and her pale eyes were translucent in the afternoon light from the windows. Her sailor-uniform skirt swayed gently with each step.
(She really is beautiful.)
He didn't bother making excuses for himself anymore.
"...Just got here."
"I see. Then let's go."
Akira fell into step beside him naturally. The distance between them was so much closer than before. Their shoulders almost touched—but didn't. That gap made Yuuta's heart tighten, slow and steady.
"Yuuta, you're really okay with this?"
Akira asked without turning to face him. Her voice had slipped back into its usual boyish tone.
"...Yeah. It's what I decided."
"You won't regret it?"
"Maybe I will. But I figure I'd regret running away and doing nothing a whole lot more."
Akira's eyes widened slightly. Then she let out a soft laugh.
"Yuuta, you really are something, you know that?"
"What's that supposed to mean?"
"That stupidly straight-arrow part of you. I've always loved that about you."
Yuuta's cheeks went hot.
"...Cut it out with that stuff."
"You're blushing. Cute."
"Don't call me cute!"
Bickering lightly, the two headed for the special wing. Summer sunlight poured through the hallway windows. July was almost over. The rainy season had ended, and real summer was on its way.
(Summer break, huh.)
Yuuta glanced up at the blue sky beyond the glass.
(By the time this summer ends, what'll have become of me?)
Fear and anticipation churned in his chest.
────────
Third floor of the special wing. When they reached the music room, Akira stopped.
"From here on, you open it yourself. I'll be right behind you."
Yuuta stared at the music room door.
How many times had his feet frozen in front of this door? First, when Akira summoned him. Then, when Mikoto's message threatened him.
But today was different.
(I'm opening this door myself.)
He reached a trembling hand toward the knob. His fingertips touched cold metal.
(It's okay. I decided this.)
He told himself one more time.
And then he opened the door.
The hinges creaked.
The music room was filled with the soft light of early evening. The window curtains swayed slowly in the breeze. Sheet music from a class lesson remained on the blackboard, and an old piano stood against the wall.
In the center of the room stood Mikoto.
Her long, blue-black hair gleamed lustrously in the light from the windows. Her large, round eyes looked straight at Yuuta. On her lips was her usual composed smile.
"You came, Yuuta."
Her voice was quiet and kind—as if she'd known all along that he would come.
"...Yeah."
Yuuta forced the word out of his throat.
"You didn't run. Good boy."
Mikoto took a step toward him. Her movement was feline, fluid, soundless.
"I didn't come because you threatened me. I came because I wanted to."
Mikoto tilted her head slightly at his words.
"Oh, is that so? Even better, then. Children who come of their own desire respond to the magic completely differently."
Her eyes narrowed. Smiling, yet not smiling. In the depths of those eyes, Yuuta saw something bottomless.
(This person really is going to turn me into a girl.)
A chill ran down his spine.
But there was no turning back now.
"Yuuta, it's okay. I'm right here."
From behind, Akira's hand rested gently on his back. The warmth of it eased his trembling, just a little.
"...Thanks, Akira."
Yuuta gave a small nod.
────────
"Now then, shall we begin?"
Mikoto lifted a large paper bag from the corner of the room. From inside, she pulled out several carefully folded garments.
A white blouse. A navy pleated skirt. A pale pink cardigan. Socks trimmed with lace.
"I prepared all sorts of things for you. Pick whichever you like."
Yuuta looked down at the clothes laid out before him.
(Choosing girls' clothes myself.)
That act was decisively different from before.
(Before, they were put on me. But today is different.)
Yuuta took a deep breath.
Then he reached for the white blouse. Next, he picked up the navy pleated skirt.
"Choosing for yourself—what a wonderful attitude. Yuuta, you really are starting to change."
Mikoto's voice lilted sweetly.
"Now, let's get you changed. Akira, help him."
"Okay. Yuuta, face me. I'll help."
Akira stood directly in front of him. Her fingers touched the buttons of his uniform.
"Relax. It's okay."
Akira's voice rang sweetly by his ear.
Yuuta let himself be undressed. His shirt fell to the floor. His pants too.
(Right now, I'm taking off boy's clothes.)
(And I'm about to put on girl's clothes.)
His heart pounded painfully.
Akira picked up the white blouse.
"Arms through."
Yuuta obediently raised his arms.
The fabric of the blouse brushed against his bare skin. Smooth and cool. When she buttoned it up, his chest felt tight.
(Because my chest has grown more than before.)
Next, the skirt.
"Step in."
Akira held the skirt open. Yuuta stepped into it.
The skirt was fastened at his waist.
(I'm wearing a skirt.)
(I chose it myself, and put it on.)
The air felt breezy around his legs. The sensation of air directly against his thighs.
"Yeah, it suits you. Come here, let's look in the mirror."
Led by the hand, Yuuta was positioned in front of the mirror.
What was reflected there—
A slender body in a white blouse and navy skirt.
Behind the angular glasses, his eyes were wide with surprise.
(Is this... me?)
"You're beautiful, Yuuta."
Akira whispered from behind him.
At those words, Yuuta's cheeks burned crimson.
"...Cut it out with that."
His voice trembled.
"It's the truth. You've got a beautiful face to begin with. And if you switched to girls' glasses, you'd be even cuter."
"The glasses... stay."
"Stubborn."
Akira giggled.
"Then next is hair and makeup. Sit here."
Mikoto pointed to a folding chair.
Yuuta sat as instructed.
Mikoto stood behind him. Her fingers touched his hair.
"Your hair's grown a little. Let me tie it up."
Mikoto's fingers deftly combed through Yuuta's hair. It was gathered and tied in a small bunch just above his ears.
(My hair's tied up.)
The reflection in the mirror changed, little by little.
Next, Mikoto brought out makeup tools.
"Close your eyes."
Yuuta closed his eyes.
Something cool touched his eyelids. Eyeshadow. A brush brushed his cheeks. Blush. A stick glided across his lips. Lipstick.
"All done. Open your eyes."
Yuuta slowly opened his eyes.
In the mirror was a girl he didn't recognize.
A girl with her hair tied up and makeup applied.
But looking closely, it was unmistakably him.
"See? Absolutely adorable."
Akira placed a hand on Yuuta's shoulder.
"This is your true form, Yuuta."
Mikoto's voice seeped deep into his ears.
(My true form...?)
(This is... mine...?)
Yuuta couldn't look away from the reflection.
────────
"Now then, let's begin. The final touch."
Mikoto stood directly in front of Yuuta.
Her hands gently enclosed both of his.
Mikoto's hands were small and cool.
"Close your eyes. Relax your body."
Yuuta closed his eyes as told.
(It's starting.)
(My body is becoming a girl's.)
Fear gripped his chest.
But beneath it, anticipation was unmistakably there.
(I want to know. What I'll become.)
"Siren magic doesn't need a special incantation. You just touch like this, and pour your feelings in."
Mikoto's voice resonated quietly.
"You chose the clothes yourself and wished for this yourself. That makes the strongest catalyst of all."
Mikoto's hands tightened.
In that instant, a faint light wrapped around Yuuta's body.
"...nn!"
The light was warm and soft.
It crawled over the surface of his body as if slowly stroking him.
(What is this...)
A tingling sensation around his chest.
(My chest... is swelling...?)
Beneath the blouse, the swell of his chest was becoming something definite. Not the faint swelling from before. A clear, weighty, girl's chest.
"...ah."
A sweet numbness spread from his chest through his whole body.
(It doesn't hurt... it doesn't hurt, but my body is changing...)
His waist tightened. His pelvis slowly reshaped. His thighs grew softer, his upper arms thinner.
(Ah...)
(This... feels good...)
A sweet sensation welled up from deep inside him. An irresistible pleasantness.
(Even though I'm scared.)
(Why does it feel this good?)
Yuuta bit his lip.
He desperately held back the sounds threatening to escape.
"Good boy. Just like that, accept the changes."
Mikoto's voice resonated directly inside his head.
"You are becoming a girl. Just like me, and just like Akira."
(Becoming a girl.)
The words sank slowly to the bottom of his heart.
(I'm becoming a girl.)
The urge to resist had already almost vanished.
The light grew stronger, bit by bit.
The changes accelerated.
"...nn, ah—!"
Finally, a sound escaped.
Strength drained from his legs, and he nearly crumpled.
"It's okay, I've got you."
From behind, Akira wrapped her arms around Yuuta's body.
"Just a little more. It'll be over soon."
Akira's warmth spread through his back.
(Akira...)
(Did you change like this too?)
In Akira's arms, Yuuta surrendered himself to the transformation.
────────
How much time had passed?
The light slowly faded.
The changes stopped.
"You did so well, Yuuta."
Mikoto's hand stroked his hair gently.
"Now you're my second cute one."
Mikoto's voice was satisfied and sweet.
"Welcome home, Yuuta."
Akira's arms tightened around him.
"...Am I supposed to say 'I'm home'?"
Yuuta's voice was a little hoarse.
But it was unmistakably a little higher than before.
(I've changed.)
(My body really changed.)
Yuuta looked down at his own hands.
His fingers were slender. Even his nails seemed closer to a girl's.
"Want to see the mirror?"
Akira took his hand and led him to the mirror.
In the mirror—
A white blouse and navy skirt.
Tied-up hair.
A face finished with makeup.
And a body with unmistakably feminine contours.
The swell of his chest was still small, but it was definitely there.
His waist curved inward.
His shoulders seemed narrower, somehow.
"...Holy shit."
He muttered.
"'Holy shit'? Is that your review?"
Akira burst out laughing.
"Well, what else am I supposed to say? It actually happened."
"It's fine. You got cuter, Yuuta."
"...I told you to cut that out."
He tried to push up his glasses to hide his embarrassment, and his fingers brushed against the tied-up hair.
(Right. I'm dressed as a girl right now.)
The fact landed heavily in his chest all over again.
"There, the final touch is complete. You did so well, Yuuta. Such a good child."
Mikoto patted his head, stroke after stroke.
Her touch was like praising a small child.
(Mikoto turned me into a girl.)
(Because I wished for it myself.)
Yuuta stared at his reflection.
Fear, joy, confusion.
All kinds of emotions churned muddled in his chest.
