Call me sister. Sister

As I waited for Meiko, my teacher, who was blushing as she looked at me, my field of vision lowered a bit more.

Early 160s… no, closer to mid-150s in height.

My height had shrunk to that of a pubescent boy, a middle schooler, or a short high schooler. It wasn’t just my height that had changed.

I had lost some muscle, my hands had gotten smaller, and my voice had changed a bit.

[The caster’s appearance has been altered according to the user’s desires.]

[Confront the desire.]

Normally, this would be a magic circle that triggers a ‘sexual desire’ event, but the heavily limited magic circle wouldn’t activate any further.

It merely sets the stage for the user to confront their desire.

But a transformation into a boy due to desire?

The other guests, turned into generals from other countries with glasses, seemed more tame in comparison.

“Y-you, how did you get younger? Could this be an illusion…?”

Meiko asked in a trembling voice as she looked at the smaller me.

“Teacher, what kind of desires do you have…?”

A androgynous voice of a boy whose voice was just starting to change.

A beautiful voice that was hard to believe was my original voice came out of my mouth.

“Ah.”

Meiko took a step back after hearing the voice.

“Teacher, don’t run away, please talk to me.”

“Ah, w-well, um…”

Meiko looked at me, not knowing what to do.

She was clearly flustered, but her eyes were filled with desire as she looked at me.

“Could it be that you were annoyed by the fact that I’m older?”

“…”

Meiko couldn’t answer and just fidgeted.

I had seen her fidget many times before, as she was a teacher who often caused trouble, but this reaction was new.

She had never shown such pure embarrassment before, and she couldn’t even make eye contact.

‘Interesting.’

Her reaction was quite amusing.

It was a completely different reaction from usual, where we always talked within the confines of being teacher and student.

Whatever else, it was clear that my current appearance as a boy was a direct hit to Meiko’s tastes.

‘With this…’

Perhaps I could persuade Meiko, who was resistant to confronting her desires.

If I could persuade her, I would gain a powerful assistant who could help with my research in the future.

“Teacher.”

Having finished my thoughts, I gave a playful smile that a boy would make.

A smile like the one you’d make when teasing a girl you like, with the corners of your lips turned up.

As I spoke with a smirk, Meiko started hiccuping.

“Hic.”

“Teacher~, don’t look away, please look at me.”

I approached her, speaking not in my usual admonishing tone, but in the voice of a mischievous boy.

“D-don’t come closer.”

“Teacher.”

“D-don’t talk in that voice anymore.”

Meiko’s breathing became increasingly rough as she spoke in a trembling voice.

“You said you’d help with the magic circle configuration. You have to tell me what desires you imagined.”

I took another step closer to get an answer.

“Ugh, I can’t take it anymore.”

Meiko, her face completely red, bit her lip.

“Disciple, you, you started this, okay?”

“Huh?”

“You’re the one who flirted.”

“What does that…”

Before I could even answer.

“Eeyah!”

Meiko ran up and hugged me tightly.

I barely had time to think that the feeling of her chest against mine was soft.

“Whoa!”

Meiko, hugging me tightly, buried her nose in the crown of my head and took a deep breath.

“Sniiiiff, haaa. Smells nice.”

“T-teacher… just a moment…”

I struggled to get out of her embrace.

But no matter how hard I tried, it was almost impossible to escape Meiko’s tight embrace.

“Where are you going? Stay in big sister’s arms.”

Meiko’s voice, slightly loosened, was filled with moisture.

Her moist voice was as if she were in a daze, as if possessed by something.

“Teacher, just a moment, we still need to talk…”

“Not teacher, big sister. Right now, Max, anyone can see you’re a little kid.”

Meiko flicked my nose with her finger and grinned.

“Say ‘big sister’. Big sister.”

“Let’s talk first…”

“No. This comes first. You said it’s a magic circle that fulfills desires, so you have to fulfill my desires first. Right?”

Meiko’s expression, as if her reins had been released, was very different from what I was used to seeing.

Meiko, who would normally be intimidated by my words and listen well, was now like an out-of-control train that I couldn’t stop.

‘This isn’t it.’

This wasn’t what I intended.

I wanted to gently stimulate Meiko, teach her the importance of desire, and have her react a little more honestly.

My desire to tease her at her new appearance was the cause of this.

I should have approached her while keeping a reasonable distance.

Who knew that line would be so conservative?

As things stood, it seemed impossible to have a normal conversation.

It would be better to fulfill her desires and give her the mental space to talk.

It was a bit strange to call a younger woman ‘big sister’, though.

“B-big sister.”

“Kyaaaa! So cute~!”

Meiko hugged me tightly again.

Then, she even rubbed her face against my cheek.

I could feel the soft texture of her cheek against mine.

“Max, you’re so cute. Your skin is so smooth.”

Meiko, holding me like a doll, smiled contentedly and stroked my hair.

“Don’t stroke my hair.”

“Are you angry at big sister? How cute.”

Wait a minute.

It felt like Meiko had become strangely high-handed, or was it just my imagination?

“Your hands have gotten so small too. They used to be so big.”

“…”

“Your cheeks are so squishy too. A disciple who didn’t have a single cute thing about him has become so cute. Hehehe.”

Meiko, smiling in a daze, wrapped her arms around my face and pressed it tightly against her chest.

“J-just a moment… ugh!”

My face was stuck between her breasts.

“It would have been so nice to have such a cute disciple! When you first came, you were already taller than me…”

The fact that she allowed me to touch her breasts, which she would never have allowed normally, showed that her brakes were truly broken.

Soft.

Even in this situation, I thought Meiko’s breasts were soft.

“Big sister, stop… I-I can’t breathe.”

Meiko finally released me from her chest as I struggled.

“How was it? Do you know how amazing big sister is now? No matter how strong Max pretends to be, you can’t beat big sister.”

“…Okay, okay.”

She sat down on the chair, smiling contentedly as she looked at me.

“Come here.”

She patted her lap and said.

“You want me to sit there?”

“Yes. It’s a special seat that big sister is specially providing.”

“…”

Unlike the other guests, I continued to feel like I was being dragged along.

‘Let’s just go along with it for now.’

Whatever the process, I had decided to face all of her desires.

I sat on her lap.

As I felt the soft texture of her lap through my butt, I heard laughter from behind.

“Haa, this is healing.”

Meiko hugged me from behind, rested her face on my neck, and sighed in relief.

She didn’t seem to notice that her chest was touching my back, or that I was losing my mind because of her soft lap.

No, Meiko didn’t seem to know that teenage boys were the most sexually active period.

“Haa.”

I heard soft breathing in my ear.

Meiko’s breathing, resting her head on my neck and inhaling and exhaling as if smelling me, was clear.

She wrapped her arms around my waist and leaned her body completely against me.

“You know, I was always teased for being the only young one among the old school leaders?”

Meiko’s voice, whispering in my ear, was deeply embedded in my ear.

“They always treated me like a kid and teased me, and when I said something, they didn’t even listen. And the only disciple I had was always nagging me, the teacher, because he was older.”

That disciple is me.

Was it because I looked young?

She seemed to have forgotten for a moment that the older disciple who nagged her was me.

“It’s true that I spent a lot of money, but I didn’t spend it with bad intentions. Weren’t they too mean?”

“…They were mean.”

“Max, you think so too, right?”

Her fingers, which had been wrapped around my waist, began to move slightly.

They moved and gently stroked my stomach.

Her hand went inside my clothes and caressed my bare skin.

“B-big sister?”

“Can I just stay like this for a moment?”

“…”

Her voice was wet and sticky.

“Haa, haa.”

Meiko’s breathing, hugging me from behind, became increasingly rough.

She wasn’t in a normal state.

Meiko’s fingers, which had come inside my clothes and started caressing my bare skin, grabbed my waist and gently stroked it upwards.

Just as her fingers were moving higher and higher.

“Are you… excited?”

Meiko’s eyes went to my lower body.

My lower body, which had been bulging due to the sensation felt from behind and the touch of her fingers stroking my body, was twitching.

This was a natural physiological phenomenon.

What kind of reaction should I show here to stimulate Meiko’s desires?

I brought my thighs together, covered my lower body with my hand, and said.

“N-no, I’m not…”

I squeezed out a voice as if I were very embarrassed.

I heard a sound as if she had been hit by an arrow.

I could feel Meiko’s body, which was touching me, trembling.

I could feel the agony she was feeling.

Her pursed lips parted.

“T-this isn’t right.”

Meiko jumped up from her seat.

“Big sister?”

“…”

Meiko, looking at me with a completely red face, bit her lip tightly and blurted out.

“I, I’m going to sleep in the lab today.”

Then, she ran away.

She hurriedly released the illusion as she ran away, and we all returned to reality.
