บท 1: I made a brainwashing device

When I became a second year student, I somehow stopped going to school. There wasn't any particular reason for it, but the change in the class atmosphere was a little bothersome, so I tried skipping class for just one day, but I ended up not attending any more.

Even though it was a small matter for me, it seemed to be important to my parents, so the school and parents had many meetings, and while I first received counseling at the school nurse's office, I gradually got used to the school. Ta.

This is probably the time when the third period of class is being held. At the empty entrance, I change my shoes and head straight to the nurse's office. This has been going on for about a month now, and it's a daily scene for me.

"Miyama-kun, thank you for coming today as well. Please wait in the next room."

The person who greets me with a kind smile is school nurse Ayako Niimura. She is a young teacher in her early 30s who was assigned to me several years ago. She has her trademark light brown ponytail, sagging eyes that match her smile, and is as tall as a man, with a model body. It has become a dream come true for students.

The teacher also serves as a counselor, and since she deals with any concerns seriously without denying them, it seems that not only the students but also the teachers come to consult her from time to time.

When I think about the fact that I am in a position where I can have such a teacher all to myself every day, even for a short time, I think it is a luxury.

The teacher appeared in the counseling room with two cups of tea. She hands me one, sits down in the chair across from me, takes a sip, and then she smiles at me.

"Has anything changed lately? Is it the same as usual?"

"Hmm, as usual."

"I see. The second year students are currently preparing for their extracurricular class. Their teacher will be accompanying them, but I'm actually looking forward to it."

"Where are you going?"

"Mountain XX is a mountain a short train ride away."

My teacher tries to keep me interested in school by talking about various things every day. But unfortunately, I don't feel like going back to the classroom after all. Especially today, my head was full of other things.

The trigger was a document file I found on a certain site. Ever since I stopped going to school, I have been living a life full of internet. During this time, I learned that there are sites that cannot be viewed without installing special software. It's called the dark web.

While watching a story that resembled an urban legend on a video site, I got curious and decided to visit it. There were a lot of sites that I couldn't believe my eyes on, and I quickly became hooked.

The file was posted without any explanation on an English-language message board for sharing leaked information. It's a place where people usually post personal information stolen from some mail order site, so I was curious and decided to download it.

It looked like a secret document from some country. When I managed to translate it using a dictionary, I discovered that it was a research paper written by an intelligence agency. Although the date was several decades ago, the contents were surprising.

The research involved using a device based on a special program to give suggestions to the subject. Simply put, it's hypnosis. Normally, hypnosis cannot give suggestions that the subject rejects from the bottom of his or her heart. So, for example, it is impossible to use hypnosis to induce someone to commit murder or to have sex with someone they do not like.

However, by using the method described in the paper, it is possible to transform even the deepest consciousness of the subject, and make it possible to imprint even the most radical hints as if they were common sense. Certainly, this is something that cannot be made public.

Attached to the document file was source code created by someone. At first glance, it appears to be a modern reproduction of the brainwashing program described in the paper.

Apparently, at the time the paper was written, devices were made by assembling analog circuits, and I managed to implement the program onto my tablet.

When I tried using it on my own mother, it had amazing effects. When I tried to introduce the simplest suggestion, ``I don't care what happens to you,'' I created a person who can continue a conversation calmly, even if water is splashed on him in front of him, or sweets are stolen from his hands. It's gone.

I wanted to test the true value of this device and could no longer stand still.

While I was reading and sleeping in bed, it was after school. There are no counseling appointments scheduled today, so the teacher has complete free time. I called the teacher.

"Studying programming? Wow, you made this yourself? Isn't it amazing! Miyama-kun is really smart!"

I used the same method of introduction as I did with my mother. Especially if you're a teacher, you wouldn't think to question something if it's likely to lead to academic success. In fact, the woman in front of her was showing a truly carefree smile. I, on the other hand, had a secret, evil smile on my face.

The device was similar to a brain-training game that was popular a while ago, with numbers and shapes appearing on the screen, and you had to press them in the order of the correct answers. If you call it a self-made game, it's enough.

"If you press the start button, it will start, right? Okay, let's try our best."

"Oh, so please put on this headset. We're playing a game while playing music."

"Should I do this?"

"Yes. Also, here's a tip: once the actual performance starts, just concentrate on the screen. If you don't, I think you'll lose right away."

"Yeah, I understand. Sensei, you look like this and you're pretty good at this kind of thing, so please take a look!"

A teacher wearing a headset touches the screen. First is the tutorial. Once that's done, it's time for the real thing. This actual game is actually a brainwashing program written in a top secret document.

The game is initially set at a difficulty level that players can barely clear. This is to use the feeling of frustration as fuel to concentrate on the work. Then, the difficulty level is slightly lowered at a timing that does not make the game uncomfortable, making it possible to clear the game. It has the effect of converting frustration into pleasure and concentrating your thoughts on one point.

Then, the difficulty level gradually decreases to the point where it is no longer perceivable, until it becomes a mere repetitive task. It's no longer interesting as a game, but all thinking skills other than work have already been shut down, so if you leave it alone, you'll continue working semi-permanently. At this time, the brain is in a defenseless state, and it seems that there is room for suggestions to be imprinted.

A randomly generated one-phrase piece of music is playing on a loop from the headset. This music has several important meanings. First, it has the ability to block external stimuli. Next is the ability to narrow your thinking circuit. And this is the key function when reintroducing suggestion after awakening.

The teacher follows the screen with serious eyes and touches it with flexible fingers. At first glance everything seemed to be going well, but inside I was getting nervous.

Actually, this program had some weaknesses. According to the paper, the program will only work if the subject has complete trust in the other person. It is said that if there is even the slightest doubt about this, the hypnotic effect will be significantly reduced.

Although intelligence agencies initially began research on it for the purpose of acquiring collaborators, it appears that these characteristics made it impractical, and the research was discontinued.

In other words, whether or not the teacher takes the hint depends on how much she truly trusts me. If the teacher doesn't actually trust me, she won't take the hint...

I observed the teacher from a distance, trying not to make any noise, so as not to provoke her any further.

It takes about 30 minutes before the suggestion can be accepted. For 10 minutes, the teacher looked at me seriously. 20 minutes in, his eyes are getting blank. After 25 minutes, her entire face relaxes and she takes on a sloppy expression that is unimaginable for a normal teacher. For 30 minutes, my mouth was half open, my eyes were staring at the day after tomorrow, and the only sound I could hear was the tap, tap, tap on the screen.

35 minutes passed, and the teacher's behavior remained the same. I took the plunge and moved in front of the teacher. When a complete alteration of consciousness occurs, the person will not wake up unless there is a strong, direct stimulus, such as a strong shaking of the shoulder.

Tons, tons, tons, tons... The teacher keeps poking at the screen with her finger. She doesn't seem to notice me. She spills her half-drunk tea on the desk. Tons, tons, tons... There is no change in the teacher's work.

I had a look of joy on my face as I wiped the device with a tissue to keep it from getting soaked. …Successful. The teacher's brain is now in a completely "closed" state.

Turn the volume of the music down to about half and speak into the teacher's ear through the microphone. This is a way to introduce hints.

``Right now, Tomoki Miyama is floating in your head. You will never change your evaluation of this person. No matter what he says or does, you will respond with exactly the same emotion. When you wake up, your consciousness will definitely be like that."

I shake my teacher's shoulder. The tension returned to the teacher's face, and her eyes widened for a moment, then she blinked a few times and looked back at me.

"Uh, sorry, sorry...I think I fell asleep for a bit."

"good morning"

"Ahaha, I guess you're kind of tired... Are you okay, Miyama-kun?"

"I'm totally fine, but do you notice something?"

"Hmm? Ah, Miyama-kun, isn't that my white coat you're wearing?"

Before I woke up the teacher, I pulled a little prank on her. I decided to try it out and see how it would react to things.

"That's right. Is it okay to wear this as is?"

"Okay. Give it back to me when you leave. Come to think of it, are you naked underneath?"

"Yes. I wore it over my naked body."

"Then, please drink some tea so you don't catch a cold."

The teacher picked up my uniform and underwear that were scattered on the desk, quickly folded them, placed them in a pile in the corner, and began pouring tea from the teapot into cups.

In response to my prank, the teacher made no attempt to express any feelings that would normally arise, such as discomfort or doubt. I treated everything as if it were a casual everyday occurrence. The hints will definitely work. I don't think it would be a problem to do something a little more daring.

"Do you put sugar in your tea?"

"Yeah, I put it in sometimes."

"Then, um, I'd like you to try it..."

As soon as I said that, I snatched the cup and biscuit from her side, stuffed the biscuit into my mouth, and chewed it down firmly like gum. When I felt that the texture was gone in her mouth, I brought the cup to the front of her chin, stuck out my tongue, and dumped the contents into her mouth.

"Please dissolve this well and drink it."

"Oh, thank you. I'll take it."

There is an ocher-colored clod-like object submerged in the black tea, and saliva slowly sinks toward it in the form of a mist. The teacher took the cup with a faint smile and began stirring it quietly, breaking up the lumps with a spoon.

The remains of the biscuits turned into fine dust and were flying around in the sea of tea. The teacher slurped it up, her face not changing at all, and swallowed it with a slight purr.

"Yeah, I think it has a gentler taste. Thank you."

The teacher is smiling carefreely at me. The behavioral response has been positive. Next, let's test the conversation.

"Now that I think about it, even when teachers are asked how old they are, they don't really answer."

"Well, it's hard to answer detailed numbers."

"Why is that?"

"As expected... once you're over 30, you want to hide your age as much as possible. But I don't want people to think you're weird, so I guess it's okay to just say it roughly."

"It's like a girl's heart."

"Maiden… But, well, you're right. Miyama-kun, you shouldn't ask women too much about their age, right?"

"Okay. By the way, how old are you exactly?"

"I'm 32 years old. I haven't told any of my students yet."

"But you're going to tell me."

"Because you're curious, aren't you?"

"Still, it's not a question you want to answer, is it?"

"Hmm...but you asked me."

I knew that whenever a student asked how old a teacher was, she always answered, "About 30." The question must not have made the teacher feel good. However, the teacher simply told me the exact age.

You can tell by her attitude that she doesn't have any special feelings towards me. Under the influence of suggestion, they are unable to notice or think about contradictory words and actions.

I asked the students various questions that the teacher had probably never answered before.

"Does our teacher have a boyfriend?"

"I'm not here right now."

"So, up until now?"

"One when I was in high school, three when I was in college, two when I was a working adult, probably."

"When did you break up with your last person?"

"It's been quite recently since I started working here. I decided to break up with him because I wanted to spend more time with the students. He thought it would be better that way, too, so that's not why we fought."

"I see.…So, do you have quite a bit of experience?"

"experience?"

"Uh, um, uh, about sex."

"Yeah, I've had sex before. Hmm...about ten...times, I think. I don't think we've had that many."

The teacher lightly presses his lips with his index finger and makes an expression as if she is trying to recall his memory.

"When was the last time?"

"It was quite a while ago. Before I came here…maybe 5 or 6 years ago…"

"Um, um, has the number of times you masturbate increased?"

"Of course! When we broke up, I was lonely at first, and when I felt sad, I just did it naturally. Lately, I've been enjoying my work so much that I've been working less, but I still do it about twice a week."

I was so excited that I was about to get over it. Ending it here was no longer an option.

"Teacher, um, I, um, want to masturbate too, um..."

I can't give instructions well because I'm nervous. He cleared his throat and spoke again.

"Well, I want to masturbate, so please show me your naked body."

"Do you want to see me naked?"

"Yes, I would like to masturbate while looking at my teacher naked."

"Okay, can you wait a minute?"

"yes!"

After making sure the room was locked, I returned to my seat and took off my white coat, taking on the appearance I was born with. The teacher was just unbuttoning her dark pink shirt and removing her arm.

"Oh, you really have an erection. Is it always like this at school?"

"No, I got excited when I was listening to the teacher's story."

"Eh, I don't know why. But I'm sure the teacher is pretty horny too."

While saying that, the teacher rolled up her black innerwear, leaving only her bra on her upper body. It was also a smooth movement, like when she was changing her clothes.

"Oh, wait a minute! Could you please take off your skirt and tights first and show me your underwear?"

"Oh, sorry. I'd like to see that too."

She moved the hand that was on her back to her waist and hooked it to her long navy blue skirt. I removed her tights from her legs, leaving her lower body in only shorts.

The teacher puts her hands behind her back and shows off her limbs.

"Yes, this is my underwear."

The teacher is wearing orthodox plain blue underwear. However, when I passed her long, sleek legs and torso that looked like high-end furniture, she looked too sensual.

And above all, the fact that this is a sight I had never even thought of witnessing until last month makes my lower body extremely happy.

While playing with my crotch, I gave instructions to follow my desires.

"Okay, teacher, please take off your underwear as well."

"Are you done?"

"If I look at your underwear, I think I Am going to come out. I want to masturbate while teacher is naked."

"Ahaha, that certainly doesn't make any sense. Well then, I'll quickly take it off, so please take your time and enjoy it."

The teacher unhooked her bra and deftly removed the top and bottom of her underwear, as if tearing them off. Then take the same pose as before.

"I've been waiting for you naked. Are you excited?"

Beautiful white, shallow, bowl-shaped breasts that appeared from under the cup of the bra. Almost in the center, a dark brown nipple the size of a soybean sits with a pedestal of areola the size of a 1 yen dime.

"Teacher, what cup size are your breasts?"

"My bra is a D, but it's about a C."

"Your nipples are erect."

"For some reason, the teacher is getting excited too. Look, it's a little wet here too."

The teacher opened her legs slightly and placed the middle finger of her right hand on the crack between her legs. He tapped it a few times and heard the faint sound of water.

Beneath the bank of thin, symmetrical hair, bright vermilion lips are slightly parted, asserting themselves in a slimy, mysterious manner.

The sight of a beautiful woman refreshingly showing off her genitals made my crotch buckle painfully.

"Thank you, teacher, I think I'm getting better at masturbating."

"Good. You can always talk to me about this."

The teacher says so, but it's not the kind of consultation that can be done easily without any hints.

"Well then, uh, please take a seat."

"Can I sit down?"

"Yes. Please sit down and be normal. I'll do the rest."

"Really? Well then, if you need anything, let me know."

I sat my teacher down in her old chair, stood next to her, grabbed my erection, and started rubbing it all over her body. A chest that gently accepts it. The sides that wrap around you moistly. And firm cheeks. When I use her wrist to slam against my cock, I enjoy the way it bounces back and forth, and I end up using her teacher's face like a musical instrument.

"...By the way, Miyama-kun, is there any place you'd like to go?"

The teacher speaks suddenly.

"Where do you want to go?"

"It's boring to have extracurricular classes in the same places every year, right? That's why the teachers sometimes come up with ideas, but I thought I'd like to hear your opinion, too."

"Is there any chance that your wish will come true?"

"Well...to be honest, it's going to be the same every year, but hey, it depends on my presentation! Maybe it'll be new next year?"

It looks like she's trying to bring up the topic while I'm masturbating. This seemed to be the result of dutifully carrying out the instructions to ``stay normal''.

"Hmm, but that doesn't mean I can't go."

"Well, third year students also have extracurricular classes, right? So, hmm, I can make some suggestions there."

"Then...would you like an aquarium? It's quiet and cool."

"Aquarium, that's great. I'll try making a suggestion at the next meeting."

When I flicked the nipple with my glans, I could see the teacher's reaction. However, she seemed to be concentrating on the conversation. Having her nipples played with and consulting with her about class coexist perfectly in her mind.

As I looked at her trembling breasts, focusing on her nipples, my crotch felt like it was on the verge of erupting.

I finally did a thorough verification.

"Teacher, I'm going to release semen, so please put it in your mouth."

"Hmm? Um, hmm, are you okay?"

"A little deeper."

"Hmm, are you sure?"

My teacher pursed her lips to prevent her teeth from sticking out, and took my rod in her mouth as far as it would go. I can feel the glans hitting the back of my throat. The roughness of the tongue sticking to the back of the mouth and the moisture clinging to the whole thing. I was able to do my best in it.

"Please drink!"

"Ngh, ugh, oh, hmmm, eh, ugh, hmmm..."

With tears in her eyes, the teacher swallowed the sperm with a loud gulp.

"Haa, haa, haa..."

When he pulls out the rod from his mouth, the teacher's sticky saliva follows him from the back of his throat. I quickly grabbed my underwear that was nearby and wiped my penis.

"Um, Sensei, please rinse your mouth thoroughly with the remaining tea and drink it."

"Eh...should I wash it?"

The teacher pours the tea mixed with my biscuit crumbs all at once and mixes it in his mouth. After about 30 seconds of that, I heard a gulp as loud as when I swallowed the cum.

The cup was covered with crumbled biscuit crumbs. I let the teacher lick it clean and then wiped his body with a wet tissue. I wanted to minimize the sense of discomfort that remained when the hints were solved.

"Ah, thank you for doing so many things for me."

"It's okay. Then, teacher, please put on your clothes and lab coat and put on this headset."

"Okay, just wait a moment..."

I put the headset on the teacher in his original form again and played the same music as before. Immediately, the teacher's face relaxed and his eyes went out of focus.

"All your memories up until now are dreams. Dreams disappear from your mind as soon as you wake up. These memories are unnecessary to you, because you were just asleep."

Hypnosis using a device will naturally break off due to sleep, fainting, or life-threatening defensive reactions, but it will remain as a memory. Therefore, we have to put him under hypnosis again and erase all the evidence.

Stop the music and shake your shoulders vigorously. When the teacher wakes up, all that is in front of him is his usual desk and his usual second-year student, Tomoki Miyama.

"Oh, I feel like I slept for a really long time..."

"I'm sorry, Sensei, but I had to hang out with you when you're busy."

"No, that's not true! The game you made, Miyama-kun, was very interesting. I was very impressed with the teacher."

"I'm glad you enjoyed it."

"Yeah, yeah...ah! I'm sorry, but it's almost time for me, so let's continue talking tomorrow?"

"See you tomorrow then."

"Yeah, thank you for coming today too."

I leave the school, waving to the teacher who starts cleaning up. On the way, I couldn't help but check the folder on my smartphone in an empty back alley. Peeking through the gap in her bag, she sees the teacher pounding her nipples with a cock. I wonder how many more times I'll get through this video...

But I didn't intend to end it there. I was determined to enjoy student life in my own way by using that device, which performed better than I expected.

Inside my damp panties, my lust slowly rears its head.
