After-School Secret Base: Bocchi-chan's Special Adult Lessons
Hitori Gotoh, nicknamed Bocchi-chan, is a high school student who loves guitar. Despite the success of her band 'Kessoku Band' at the school festival, she's still terrible at talking to people.
One day after school, Hitori is crying on the rooftop. A classmate who saw the festival video told her 'your guitar is great' and she got so nervous she ran away. That's when she's found by Ijichi-senpai from the neighboring class. He's kind and popular with everyone, but he hides a secret no one knows.

Her fingertips still remembered the warmth of his hand.
Since that day on the rooftop, Hitori's time had passed with a strange quietness. During class, during lunch break, even during Kessoku Band practice, some part of her heart was always waiting for the "next time." Every time she spotted Ijichi-senpai walking down the hallway, her chest tightened. But senpai, as always, wore that gentle smile for everyone, and the expression he had shown only to her on the rooftop felt like nothing more than an illusion.
After school.
Hitori slumped over her desk, berating herself for yet another day of accomplishing nothing. Her classmates' conversations sounded distant. Outside the window, the town of Sosai was beginning to stain with twilight. The view from Private Sora High School, perched on the heights of Otowadai, was beautiful today as well. But that beauty, paradoxically, only seemed to emphasize her own insignificance.
"Goto."
Called by name without warning, Hitori jolted, her body trembling. When she lifted her head, Ijichi-senpai was standing at the classroom entrance. His long jet-black hair was casually tied back, and his deep crimson eyes quietly watched her. The silver piercing in his left ear glinted, catching the sunset.
"Come. Special practice."
His voice carried a tone that allowed no refusal. The few students still remaining in the classroom glanced their way. Their faces said it all — it was rare for senpai to speak to Goto Hitori. Hitori's heart began to pound like a frantic drum.
"Ah, yes... I'm coming now..."
She stood on trembling legs and clutched her guitar case. Senpai was already walking down the hallway. Hitori chased after his retreating figure, nearly tripping over herself.
The connecting corridor leading to the special wing. After school, this path was almost entirely deserted, like an entrance to another world. The white walls and pale blue roof were dyed orange by the setting sun. Only their two sets of footsteps echoed, clack-clack, clack-clack.
Senpai said nothing.
Hitori couldn't say anything either. She just walked, staring at his back. A person who was tall, with broad shoulders, whose guitar-playing fingers were long and beautiful. The perfect senpai, popular with the entire school, kind to everyone. But that face he had shown on the rooftop was completely different. The person who had grabbed Hitori's hand back then had looked at her with the eyes of a predator.
(*Scary.*)
Some part of her heart thought so, yet her feet followed senpai of their own accord. There was a part of her that wanted to taste that heat in her chest from that day once more.
The very back of the third floor.
In front of the door to the Second Music Room, senpai stopped. A heavy, fully soundproofed door. This room was normally used by almost no one. There were windows, but the blinds were always shut.
Senpai took out a key and opened the door.
"Get in."
Hitori readjusted her grip on the guitar case, took a small breath, and stepped inside.
Inside the Second Music Room, the clamor of the outside world was completely inaudible. The soundproofing was so perfect that when the door closed, a silence spread as if they had been severed from the world. Several guitars hung on the walls, and dust-covered amps and a drum set sat on the floor. The air was slightly musty and cool.
—This was the sanctuary.
A secret place within this school where no one could disturb them.
Senpai took a guitar down from the wall.
"You're giving this to me. Starting with basic drills."
A tone that brooked no argument. Hitori took the guitar as she was told. Her fingers trembled. Her left hand, pressing down on the strings, wouldn't move properly.
"U-um... what should I play...?"
"Play whatever you want. Let me hear your sound."
With trembling fingers, Hitori desperately began to play. The song they had performed at the school festival. A melody she had practiced hundreds of times, one her fingers remembered. But now, those fingers were frozen. The sound wavered. It was a performance so clumsy, even she could tell how bad it was, vibrato and all.
And yet, senpai listened with a serious expression.
When she finished playing, silence returned to the room.
Senpai slowly approached.
"You're good. As expected."
At those words, a warmth spread deep within Hitori's chest. Again. This person's words of acknowledgment pierced her heart more deeply than any praise from anyone else.
"But."
Senpai's voice was suddenly close. Before she could turn around, he was standing behind her.
"Right here. You're stiff."
A hand was placed on her shoulder.
In that instant, Hitori's body jolted violently. Her fingers slipped from the strings, producing a strange sound. Being touched by someone was, in itself, almost a first for her. And on top of that, in a closed room like this, this close—
"U-um...!"
"Calm down. Relax your strength."
Senpai's voice whispered right by her ear. So close she could feel his breath. His large hands slowly began to knead the area around her shoulder blades.
"Your shoulders are rock-hard. You can't produce a good sound like this."
Senpai's fingers, as gentle as if caressing guitar strings, yet with certainty, unraveled Hitori's tension. From her shoulders to the nape of her neck, then his fingers moved as if combing through her hair.
"Scared?"
The same words as on the rooftop.
But now, though trembling, she shook her head. Scared. She was terribly scared. But being touched by this person's fingers made her feel, for the first time in her life, that her body had meaning. That she was needed by someone.
(*What... is this?*)
Heat gathered behind her eyes, and tears welled up.
The sound of the guitar stopped completely. The room was deathly silent, and only the sound of her own heartbeat seemed unnaturally loud.
What broke that silence was senpai's fingers.
Her chin was tilted up, firmly.
Deep crimson eyes gazed down at Hitori from up close.
"You're cute, so have more confidence."
—Cute.
Words she had never been told.
(*Me?*)
Confusion. Before her mind could process what was being said, senpai's face drew even closer—
His lips touched hers.
They were soft, and warm.
Hitori's mind went completely blank in an instant. She didn't understand what was happening. The only thing her senses conveyed was that senpai's lips were covering her own.
"Nn... ngh!"
She tried to escape. Twisting her body, attempting to step back. But senpai's arm wrapped around her back, holding her firmly in an embrace, and she couldn't move.
And then, his tongue entered.
A slick sensation forced its way past her teeth, intruding into her mouth. Senpai's tongue entwined with Hitori's. Lukewarm, slippery, the feeling of their saliva mixing together, independent of her will.
(*This... is a kiss...?*)
Her first kiss wasn't just gentle. It felt like being dominated. Like having everything taken from her. A frightening feeling, as if she was ceasing to be herself.
And yet—
The backs of her knees tingled.
A sensation she had never felt before, as if the core of her brain was going numb, shot through her body.
(*Does it... feel good...?*)
The moment that thought surfaced, tears overflowed from self-loathing. It was supposed to be scary. She was supposed to want to run away. So why did her body want more?
The long kiss ended, and senpai's face pulled away.
A thread of saliva glistened silver between their lips before snapping.
Senpai smiled, satisfied.
"Good girl. I'll teach you more."
That voice, though gentle, was terribly cold. It had a ring to it, like toying with prey.
Senpai's fingers went to Hitori's uniform blouse. The first button was undone with a pop.
"P-please... stop..."
Her voice trembled, as small as a mosquito's whine. So small she barely knew what she was saying herself.
But senpai's fingers didn't stop. The second button. The third button. Her blouse fell open, revealing pale skin beneath.
"You're not just special at guitar. Everything about you is special."
At those words whispered in her ear, her body reacted on its own again. It was supposed to be scary, yet there was a part of her that felt happy being called special.
Her blouse was completely removed and fell to the floor.
There was a mirror in the corner of the room.
In the full-length mirror leaning against the wall, her own figure was reflected. Disheveled hair. Eyes wet with tears. An open uniform. The modest swell of her chest, clearly visible above her bra.
(*I... looking like this...*)
She felt like she could die of shame. She had never shown this appearance to anyone.
Senpai, as if savoring Hitori's embarrassment, groped her chest over her bra.
"Hya... ah!"
An involuntary strange sound escaped her. Senpai's fingers found her nipple through the fabric and rolled it around.
(*What is this... what is this...!*)
Every time she was touched, her hips jerked on their own. Her strength drained away, and she couldn't remain standing. Leaning against senpai's chest, she somehow managed not to collapse, but her legs were shaking violently.
"You're feeling it."
Senpai's voice was clearly laced with pleasure.
"I-I'm not... please stop... I'm begging you..."
She shook her head, crying. But her body was honest. Every time her nipples were toyed with, her breath quickened, and her vision flickered.
Senpai's other hand slid smoothly downward.
Her thigh was stroked over her skirt, and her body jolted. The fabric of her pleated skirt was being bunched up by senpai's hand. Her knees were hidden, her thighs exposed.
"Don't move."
A low voice. A command.
Hitori's body couldn't disobey that command.
A hand slipped under her skirt. The sensation of fingers gliding up the inside of her thigh. For the first time in her life, someone's fingers were approaching her most embarrassing place.
(*No... even though it's wrong...*)
Over her underwear, a finger traced along her slit.
In that instant, a shock like lightning racing through her entire body shot through her.
"Ah... aaah...!"
A voice leaked out, ignoring her will. She herself could feel that her underwear had been disgustingly wet for a while now. It was proof that she was happy to be touched. And that, too, was an unbearable humiliation.
"You're wet. It feels good, doesn't it."
"N-no... it doesn't... ngh..."
Senpai's fingers continued to slowly trace her slit over her underwear. A squelching sound. Something that had come from her own body was making noise. That fact made even more tears spill over.
(*It doesn't feel good... I want him to stop...*)
Even as her heart thought so, her hips moved, chasing senpai's fingers. Her body was screaming for more, to be touched more.
That gap was driving her insane.
Wanting to be touched more—
The moment she became aware that this desire existed within her own heart, Hitori couldn't bear it any longer.
"Please... forgive me... already..."
She collapsed to her knees, sinking to the floor. Her skirt was disheveled, her blouse still off. Her guitar lay discarded nearby. The tears wouldn't stop, blurring her vision.
Her body didn't feel like her own anymore.
Senpai looked down at Hitori like that and smiled quietly. It was gentle, yet a cold flame flickered deep within his crimson eyes, an expression as if he was enjoying watching his wounded prey become unable to move.
"I'll let you off for today."
At those words, a feeling of relief and a slight sense of disappointment welled up simultaneously, making her hate herself.
Senpai crouched down and gently stroked Hitori's disheveled hair.
"Next time, I'll make you feel even better."
Next time—those words seeped into her heart like poison.
(*Next time... even though I hate it...*)
But she could no longer deny that somewhere in her heart, there was a part of her waiting for that "next time."
The silence of the music room returned once more. Hitori, collapsed on the floor, and senpai, looking down at her. Their two figures were diml
