Author Note:

This time I have included the contents of the request received from Reverie-sama on March 16th. Thank you very much for your request.

"Haaaa~~ help me Genius Professor~~"

My name is Tatsumi Nanami. Right now I am in the middle of my last spurt of studying for a so-called test. I spent all of the weekdays playing around, so this weekend I'll have to study by any means necessary to prepare for my test at the beginning of the week.

However, the scope of the test was so wide that as I was grappling with the material, my ability to concentrate was worn out to the point where I wanted to seek help from an individual I didn't know very well. Before I knew it, I had started up my computer, and was gazing at the list of commercial voice recordings on the download market site.

Yup, at times like these, rather than studying sluggishly, it is more important to take a break for once to refresh yourself. And, to me right now, listening to the hypnotic voice lots in order to build my resistance to hypnosis is just as important as studying for the test.

"……oh, Genius Professor?"

When I was dazedly staring at the screen, I suddenly spotted the person whom I had arbitrarily muttered about. The t.i.tle of the voice recording was [Genius Professor's Humanity Happiness Plan]. The listener becomes the Professor's a.s.sistant and supports her research.

"I see……so it's like that."

I read the explanatory note and completely understood the details of the story.

I'm sure it's a pattern where the Professor who makes a dreadful invention ends up suffering from the loneliness of holding such a mighty power! And then, the only one who can heal that loneliness is her a.s.sistant, me. Such a development would be within my preferences. I love that sort of sci-fi.

"Wait for me Professor, I'll go over there now!"

When it ends, I'll definitely resume studying for my test! I'm just gonna take a little break!

As I told myself childish excuses like that, like usual I dove into the world of the hypnotic voice.

◆◆◆

[We've done it, we've finally completed the device that will make humanity happy!]

"You did it, Professor!"

I am Professor's a.s.sistant in this research lab. Today, the device that the Professor has been researching up until now has finally been completed. Even I, who has been a.s.sisting her, don't understand the structure of the device at all. But, since Professor has a n.o.ble dream in which she wants to make all of humanity happy, there is no doubt that it is a wonderful device.

[All that's left is to actually test it on someone……umm……this may be hard for me to propose this myself but……]

"Please leave it to me, Professor! I will be your test subject!"

[……thank you. I believed that, if it was you, you would say that.]

I have always supported the Professor up until now. I am thankful that Professor will be able to rely on me in the future too. With that in mind, I volunteered to become the test subject of my own accord.

I once again looked up at the completed device. The main body had a large cylindrical container that could easily contain a single adult. Its walls were transparent, and resembled a gigantic graduated cylinder. The light from the countless meters that were connected to the device, faintly lit up the gloomy laboratory.

"Then, first where shall we start from——"

When I turned around, my words came to a stop. The Professor suddenly stabbed a small syringe into the nape of my neck. I lost my strength and crumbled on the spot. Amidst my dimming consciousness, the last thing I saw was the Professor's ominous smile.  

◆◆◆

"Uu……wh-where is this……?"

Shaking off my blurred consciousness, I woke up. My body felt heavily restricted, and the surrounding scenery appeared warped and enlarged. No, it wasn't my vision that had gone strange. My surroundings were encircled by acrylic gla.s.s. I realized that I was inside that cylindrical experimental device.

It was natural for me to be inside the device, as I had offered myself up as a test subject, but then I recalled the Professor's last actions. I was obviously placed inside this device forcibly. When I suddenly sensed an uncomfortable feeling in my body and looked up, both my hands were bound by handcuffs at the top of the device.

"Wh!? No way……why……!?"

In a state where those handcuffs were hanging me up, my movements were sealed. It was at a height where my feet just barely touched the bottom of the device by standing on my tip-toes. My clothes were completely stripped off, and since both my hands were restrained, I couldn't hide any part of myself.

[Ufufu, I see you've awakened. How are you feeling?]

"Professor, what exactly do you mean by this! Wasn't this a device to make humanity happy!?"

I turned towards the Professor from inside of the device and shouted. It seems that we could hear each other mutually, as the Professor responded to my question.

[I didn't lie about that. It is just that, I need to destroy a bit of your personality, so that you will become a slave that obeys my orders without thinking. That will become your happiness.]

"N-……no way……!"

I became speechless at the Professor's words. Isn't that like a brainwas.h.i.+ng device? Even though I believed in the Professor up until now, to think that the true form of the device to make humanity happy was something that dreadful……

"Please wake up, Professor! Even if you do something like that, humans will not become happy!"

[You'll only be saying that for now. Once the experiment ends, you'll even be thankful towards me. You'll say, "Thank you for making me a slave".]

It's no good. My words weren't reaching the Professor's heart. If it's like this, then I'll have to endure this experiment, and show her the strength of the human will.

"Professor, you are wrong! I will not lose to this sort of device! I will definitely persuade you!"

◆◆◆

"HonyoooooOOOOHH♥♥ Wash dishhhhhh♥ Mwy head ishhh gonya bec.u.m shtupidddddDDD♥♥"

Inside of the device filled with aphrodisiac, I made an outrageous face while showing a disgraceful sight. After that, she immediately started to operate the device, and a ma.s.sive amount of pink-colored fluid poured into the cylinder. Right now, everything below my neck was being immersed in aphrodisiac.

[*giggle* According to the measurements on the vitals machine, it seems that it has completely put your s.e.xual excitement under its control.]

"Haa, haa♥ Aheeeeeeeeeee………….♥ Ah, ah, ah♥"

I couldn't understand half of the Professor's words. The sweet, syrupy stench emitted from the aphrodisiac filled all of the air inside of the device. Just breathing in stole away my ability to think. It felt like both my lungs and brains were being dyed the same pink color as the aphrodisiac.

[Thanks to the system that adjusts the level of the aphrodisiac so that the subject is just barely unable to reach o.r.g.a.s.m, right now your climaxes are completely under my control.]

"Nn, nn, nn♥ Whyy♥ Even doh it feelz guud♥ I cyan't c.u.m at alllllll♥ Ah, ah, ah♥ Haa, haa♥"

Whenever my excited reached a peak and it felt like I was about to climax, for some reason that wave instantly withdraws, just leaving irritation behind. I tried to twist my body around in order to somehow obtain some sort of stimulation, but just feeling the resistance from the gently flowing liquid simply made that empty feeling grow further.

[Humans who are immersed in this aphrodisiac will go into an easy to brainwash state. That is why you will soon understand my dream.]

"Haheeeeeeee……♥ P-Professor'ss dreamm?"

Not good, I shouldn't listen to Professor's words. However, even though my head was cautioning me so, my body was accepting the Professor's everything. Allowing the Professor's thoughts to penetrate my entire body together with the aphrodisiac felt comfortable. I didn't have any way to resist it.

[Using this device to make all of humanity do as I say is my true objective. All of the humans who despised me up until now, and all of the humans who are in a higher position than me – all of them. As a test subject, I will have you become my very first slave. Don't you feel honored?]

"Nheeee……♥ Aiii……won't becyum sumthin'♥ Ah, ah♥ like a slaveeeeee♥ Oho, oh, oh♥"

Even so, I tried my best to preserve my mind. Though my brain felt like it was about to go strange from the continued stops just before climaxing, I still wasn't defeated.

[You still have enough strength to resist. Don't worry. Though I say 'slave', I will just be implanting good will towards me so that you absolutely will not betray me. That's right, you love me. If it's for my sake, you can do anything.]

"Ah, aeeeh? I…like? Professorr……oh, oh, oh♥ Ahee♥  Lovee♥ Huhh? Wait, no th, ah, ah♥ "

The stimulus from the bubbles that sometimes rose up from the bottom of the device churned up my thoughts. The bubbles gently caressed me from the tips of my toes to my b.r.e.a.s.t.s – as if they were licking my entire body as they rose, eventually popping as if they were satisfied and disappearing.

[Ufufu, everything – even the bubbles that seem like they're occurring by chance – is as planned. Let's see, if it's like this then perhaps it will be more effective for you if we increased the number of bubbles.]

When the Professor operated the panel, the bottom of the device made a low clanking sound. In the next instant, bubbles started to gush out from countless holes.

"AhiiIIIIIiiiiiiiiiii♥ Sh-Shtoppppppppppp♥ Being hyit by buhbblesss feeelshhh guuuuuuddddd♥  Shtopppppppppp♥"

The bubbles that blew out like a jacuzzi engulfed my entire body. It was a controlled stimulus so that I absolutely would not c.u.m. Being given such a half-baked stimulus was much tougher than not being given any stimulus at all. My entire body felt like it was half-dead from the bubbles' caresses.

[You are my slave. You love me. There's no need to think. Just obey orders. You are my slave. You love me. Love. Love. You are…a slave.]

"OH, OH, OH♥ LUVVV♥ PWOFESSORRRR♥ NHIIII♥ I LUVV YOUUUUU♥ NOO♥ WAITT♥ AIIIIIIII♥ WON'T BECYUM A SLAVEEEE♥ OHOO♥"

The Professor's muddy stream of words washed me away. When I thought of the Professor, the depths of my abdomen clenched, and my chest tightened. The sensation of the bubble stimuli a.s.saulted my entire body.The me up until now was disappearing, just like the bubbles that burst open before my very eyes

[It seems like things are going quite well. Well then, just one last push……and-]

This time an even louder sound than before rang out, and the entire device started to move. The base of the device that was comprised of multiple structures started to slide in all directions, and the main body – the cylinder filled with aphrodisiac – rocked violently.

"Oh, oh, ohh♥ Nnah♥  Ohoo♥ Ah, ah, ah♥ Sh♥ topp♥ Make♥ it♥ NO♥ AH, AH, AH♥ MY HEAD♥ IS♥ GONNYA♥ GO♥ WEYURD♥"

Every time the device moved, my head was jolted and my sense of balance went weird. The jolting brought forth a current in the aphrodisiac, and my entire body was enveloped by a sweet stimulus as though I were being chewed up by an enormous organism. My reason and my l.u.s.t – all of it got mixed up and I didn't know what was what anymore.

"P-Pweeeshhhhh♥ Let me c.u.m alweadyyyyyyyy♥ Nn, nn, nn♥ My head ish gowing weyurrdddd shooooo♥ Ret me orgashummm wihh all my myighttttttt♥"

Having finally reached my limits, I unconsciously screamed that. Even though my entire body had become sensitive, being teased by the liquid while in a state of being unable to c.u.m drove me crazy.

[Nfufu, you finally became honest. Then for the finale, make the declaration of your complete and absolute submission while using your own hands to make yourself feel good.]

The Professor said that, stopped the device, and the aphrodisiac was sucked up by the drain. When the device was completely empty, the handcuffs were removed and I was carelessly dropped to the bottom of the cylinder.

I-I'm free? Alright, then this time I'll say it for sure. I'll face the Professor, and tell her that her experiment failed. That this plan was wrong. I won't become your slave……!

"……ehehe, eheheheheeeeee……♥ For making me Professor's slaveeee♥ Thank you sho vewy muuuuuuuuccccccchhh♥ Please watchhhh♥ Witness my o.r.g.a.s.m as declaration of my complete submissionnnnnn♥♥"

Heart marks were floating in my eyes as I lifted my head. That's right, I'm my beloved Professor's slave. It's fine if I don't think anymore. Just obeying Professor's orders is my happiness. My everything.

With even my brain tissue having been completely invaded by aphrodisiac, I no longer had the strength to think anything anymore. In order to show the Professor, I spread my thighs widely and started to m.a.s.t.u.r.b.a.t.e. Right now, after being immersed in the aphrodisiac, my entire body had become an erogenous zone, so no matter where I touched a destructive pleasure attacked my brain.

"AhiiiIIIIIIIIHHHhhhh♥♥ OH, OH, OHH♥ KUHYUUUUUUUUUUNN♥ CUHMMING CUHMMING CUHMMINGGGG♥♥ AII♥ AIMMMMM♥ GONNYA BECYUM AN EMPTY-HEADED PERVERTED SLAVE DAT CYAN'T THINK OF ANYTHINGGGGG♥♥"

Having been continually teased, I quickly reached my first climax. Even so, the heat in my body did not settle at all.

"OhyoooOOOoooOOHHH♥♥ AI LUV HAVIN' MY p.u.s.s.y ALL SYOPPING WETTTT♥♥ PROFESHURRRRR♥♥ I LUV PROFESHHURRRR♥♥ PROFESHURR♥♥ PROFESHURPROFESHURPROFESHURRRRRR♥♥"

I did nothing but dig at my v.a.g.i.n.a while thinking about the Professor. I violently moved my hands as if to vent everything that had been restrained up until now.

"AHH♥♥ c.u.mMING AGAINNN♥♥ AI'LL c.u.mM FOREVAAAA♥♥ USE ME HOWEVAA YOU WANTTT♥♥ I'M GONNYA BECYUM A PERVERTED SWAVE DAT WUVS TO BE MANIPYUWATEDDD♥♥ NN, NN, NN♥♥ CUHMM, CUHMc.u.mCUHMMINGGG♥ CUHMMINNGGGGGGGGGG♥♥"

Confessing my feelings about the Professor, I earnestly left everything to my l.u.s.t, indulging in the pleasure while continuing such a destructive masturbation until my voice withered.

"Haa, haa…………..ah♥ …………Profeshurrrr…….luvvv……haa, haa……nn♥ ……………"

After o.r.g.a.s.ming countless times, I collapsed face up, but even so, my hand continued to weakly play around with my p.u.s.s.y. Just the wet squelching sound continued to resound in the laboratory.

[Ufufu, I wonder if you are happy right now?]

When the Professor looked down at me smiling and asked me that, I answered like this from the bottom of my heart.

"Happweeee…….♥ I'mmm…….♥ vewyyy happweee wight nyowwwww………♥"

"There's no way I could be happy……"

The holiday in which the day had long gone dark. I felt despair at my test preparations that weren't even half-done. Even though I had been planning to just take a short break, I had made such a mess that the clean-up took several hours.

"Just what in the world did I do for things to get that bad……"

This time I feel like I was screaming something outrageous while masturbating, but I couldn't remember properly. In the midst of the irritating feeling of being unable to remember the dream I saw, the question of whether or not I was happy remained in my heart.

……it could be that things were starting to head in a slightly bad direction. Right, this is the time to turn away. That is what my intuition was telling me.

"UUUuuuu……..i-in any case, right now I have to study for the test……!"

Procrastinating everything is my bad habit. Using studying for the test as an excuse, for now I decided to drive away the thoughts about the hypnotic masturbation.
