Vol. 2 Chapter 1 – The Arrogant Sisters, the Private Tutor and the Hypnosis Device

Masato Shimamura had spent years being ordered around, bullied and treated like a servant by the older, arrogant sisters who lived nearby──Haruna and Serina Shinjo.

He had felt relieved when Hina left their hometown to continue her studies, but with her wedding only six months away, Hina had returned to the Shinjo household for the first time in quite a while.

‘……Haruna-san has always been beautiful and smart……’

Both Shinjo sisters had successfully passed the entrance examination for the academy that Masato was now planning to apply to.

Knowing this, Masato’s mother had, of all things, asked Haruna to become his private tutor. Of course, she would be paid for it.

“You can’t even understand a workbook like this? You’re seriously stupid.”

Their study session had only just begun in his room, yet Hina was already looking down at him with contempt.

She was a beautiful woman with long blonde hair, but her attitude was mercilessly harsh.

‘It’s amazing she managed to get engaged when both her mouth and personality are this awful……’

And on top of that, her fiancé was the eldest son of a prestigious local family who worked for a top-tier company.

‘……Well, she is beautiful, I guess, and more importantly, she’s got incredibly huge breasts……’

Haruna was wearing a blue outfit with a plunging neckline, emphasizing her greatest asset──her enormous breasts to the fullest.

“Are you even listening properly? You’re slow, you’re stupid and just looking at you pisses me off.”

“H-Heheheh……s-sorry……”

Masato apologized with a servile grin on his face.

However, Haruna’s expression twisted in displeasure.

“I’ve been telling you since forever to stop laughing like that because it’s creepy, haven’t I? You don’t have even a shred of manliness in you. That’s why you’ve always been getting bullied ever since we were kids.”

‘……That’s rich coming from someone who’s bullied me plenty herself……She probably acts all sweet and innocent in front of her fiancé……Ahh, why am I always the one who has to go through this……?’

At this rate, his entire summer vacation would be spent getting insulted nonstop.

Just as he was sinking into despair, the door suddenly flew open with tremendous force.

“Sorry, Big sis! I’m late! Wait──I barely made it in time!”

The one who entered the room was Haruna’s younger sister, Serina. She was a dark-skinned gyaru whose teased-up brown hair and enormous breasts immediately stood out.

Serina’s eye-catching red jacket said everything about her love for flashy fashion.

“All right, I’m heading out. Serina, keep an eye on Masato and make sure he doesn’t slack off, okay?”

Despite accepting the job as his private tutor and being paid for it, Haruna casually abandoned her duties.

With her queen-like personality, even her younger sister Serina was practically under her command.

“Okay, Big sis, leave it to me! Now then, guess I’ll read some manga! What the──the latest volume isn’t here! Make sure you buy it, Masato!”

Compared to her older sister, Serina was less harsh but she was also much more selfish.

“I’m supposed to be watching you, so if you slack off, I’m totally telling Big sis, got it? Seriously, this is such a pain……Oh, I don’t have this manga. I’m taking it with me!”

And ever since they were kids, Serina had also been a habitual『borrow-and-never-return』offender.

‘……Why did I have to end up living near these two……? Thanks to them, I’ve basically been living like a servant this whole time…… Things had finally been peaceful for a few years, too…… Apparently her new house is going to be around here, so I wonder if she’ll still make me run errands for her even after she gets married……’

Feeling thoroughly depressed, Masato began studying, though he could hardly concentrate.

A week had passed since the private tutoring began.

“……Haa……”

A sigh naturally escaped Masato’s lips as he walked outside.

‘……Rather than having her teach me, it feels more like I’m just being used as a punching bag……’

He had been subjected to insults ever since he was little, but this time it was especially harsh.

He had gone out hoping to clear his head, but it did nothing to lift his gloomy mood.

‘I’ve got tutoring again this afternoon, but I really don’t want to go home……’

As he continued wandering aimlessly, he ended up getting lost in a back alley of the entertainment district──somewhere he would normally never go.

‘Huh? Where am I? If I hang around somewhere like this, some weirdo might come mess with me……’

Masato was about to head back toward the main street when he suddenly heard a strange sound.

“……Jubu, jukku, chu, juruuu! Juppo! Jupuryuuu♪”

‘……Huh? Could that be……?’

Those lewd sounds were something he had only ever heard in adult videos. They were coming from even deeper inside the back alley.

Driven by curiosity, Masato headed toward the sound and cautiously peeked around the corner.

What entered his field of vision was a beautiful woman crouching down and vigorously sucking the penis of a man who looked like a salaryman. She had short hair and wore a white suit, but not only were her breasts exposed──even her nipple were completely visible.

“Uoooh, that’s good, Azusa-chan! You really are amazing!”

“Njuu, jububuuu♪ Fufu♪ Your thing’s gotten really hard, hasn’t it?”

“Of course it has. I’m getting a blowjob from a beautiful woman like you!”

The sudden sight of an outdoor blowjob made Masato freeze stiff.

‘Whoa!? What the hell are they doing in a place like this……!? And damn, she’s incredibly beautiful! Yet she’s giving such an erotic blowjob!’

Despite his confusion, Masato couldn’t tear his eyes away from the beautiful woman’s blowjob.

“Nfufu♪ Well then, I guess it’s about time I make you ejaculate a whole lot into my mouth, hmm? Nn, nguu♪ Nn, nkuu, jubuu……♪ …………Hm?”

Masato’s eyes met those of the beautiful woman called Azusa.

‘Crap!? She noticed me!?’

Worse still, not only had Masato’s entire body gone stiff, but his crotch had hardened as well, visibly pushing up against his pants.

“……Fufu, another customer, perhaps? How nice…… Having someone watch while I suck is pretty exciting too. Njuu, jubu♪ Jububuu, jupuryu♪ Jupuu♪”

Rather than stopping the fellatio, Azusa narrowed her eyes with a lustful look and began sucking the man’s penis even more vigorously.

“Whoa, Azusa, you really are one hell of a pervert! Well, I guess this kind of thing isn’t bad either. Having someone watch makes it pretty thrilling!”

The salaryman seemed amused as well, completely unfazed by the situation.

‘Wh-What the hell is with these people……?’

His brain still couldn’t process what was happening, but his crotch alone continued to follow his instincts, growing even harder.

Meanwhile, Azusa’s piston-like blowjob became increasingly intense.

“Juu! Jubuu! Jujuu♪ Juguru! That’s it♪ Cum lots and lots into my mouth! Ju, jururuuu♪ Jujuuu! Jurururuuu♪ Juzuuu!”

“Uoooh, I’m coming! I’m gonna cum! I’m gonna cum in your mouth, Azusa-chan! Here it comes! Uaaaaah!”

The salaryman violently thrust his hips forward, apparently ejaculating deep into Azusa’s throat.

“Nnnnnーーーーーー♪ Nju, ju, juuuuuuu♪ Jujujuuuu!”

In response, Azusa hollowed her cheeks and countered by sucking even more intensely.

‘She’s unbelievably erotic………… U-Ugh…… I’m so jealous……’

Lately, Masato had been building up not only stress, but sexual frustration as well.

‘If only I could take out all my anger and sexual frustration on Haruna-san and Serina-san, that would feel amazing!’

Even as he shouted that impossible wish inside his head, Azusa continued sucking on the penis and draining the semen from it.

“Aaah! Cumming with Azusa-chan in a back alley feels incredible!”

The salaryman cried out in delight, continuing to thrust his hips as much as he pleased.

Even then, Azusa continued accepting his ejaculation with a thoroughly satisfied expression.

‘She’s so beautiful, yet she’s practically like a human sex toilet!’

Masato was almost moved by the beautiful woman’s utterly obscene appearance.

Azusa looked toward him and gave a suggestive smile, then deliberately tilted her face upward as though showing off before swallowing the semen.

‘W-Whoa! Amazing! She’s actually drinking it—the semen!’

“Gulp, gulp……ngh, nfuuu……gulp, gulp♪ Chupuu……puaaah……♪ Fufu, thanks for the meal♪”

The sight of her seemingly savoring every drop of semen was both exceedingly lewd and beautiful.

Masato was overwhelmed by how erotic it was.

“Haha, you’re welcome. That felt incredible, Azusa-chan.”

“Kusu, there was more than usual, you know? Did having someone watch you turn you on?”

“Yeah, this kind of thing is nice once in a while. ……Oh, look at the time! Well then, see you again!”

The salaryman left the alley with a thoroughly refreshed expression.

“Fufufufu♪ Well then, next up is……your turn♪ Normally I don’t accept first-timers, but I’m in the mood today, so I’ll give you some special service♪”

Azusa approached him with eyes like a predator stalking its prey and licked her lips.

‘Whoa, what do I do!? At this rate, I’m gonna get eaten!? Am I about to lose my virginity!?’

Just as Masato stepped backward, the door to the bar beside Azusa opened.

“Hey, Azusa. Leave him alone.”

“Ah, Ryusuke-sama!”

The man Azusa called Ryusuke-sama looked suspicious at first glance.

He had long hair, unshaven stubble, and wore a worn-out white shirt.

‘Wh-What’s with this dangerous-looking guy……?’

That suspicious-looking man──Ryusuke──stared intently at Masato before speaking.

“……You’ve got the eyes of someone who’s being oppressed by women.”

“Eh!?”

Masato flinched, startled that the man had hit the nail right on the head.

“……A long time ago, I had the same look in my eyes as you do now. That’s why I know. There’s no mistaking that servile expression.……But deep down, more than anyone else, you want to dominate women, don’t you?”

“Hmm, now that you mention it, he does kind of have the same vibe Ryusuke-sama used to have, doesn’t he?”

Azusa also nodded repeatedly in agreement.

“See?”

“Huh? Um……yeah, I guess……”

“Well, we can talk about the rest inside.”

Ryusuke opened the door and entered the bar.

‘Is it really okay to follow him……?’

Masato hesitated for a moment, but then followed after him.

“Oh my, welcome back, Ryusuke-sama. And as for you……is this our first time meeting?”

Behind the counter stood a mature woman with perfectly applied makeup.

She wore an outfit resembling something worn by a hostess, with a deeply plunging neckline, yet for some reason she gave off a strangely maternal aura.

“U-Um, yes, nice to meet you……”

Masato greeted her awkwardly, visibly unsure of himself.

Ryusuke immediately explained the situation.

“Azusa was giving one of her back-alley services when he happened to see her. She looked like she was about to devour him next, so I brought him in here.”

“My, my. You shouldn’t do that, Azusa-chan.”

“It’s fine. He didn’t exactly seem opposed to it.”

“I suppose introductions are overdue. I’m Ryusuke Otomo. I’m an investor in this establishment, 『Gentildonna』. The woman behind the counter is the owner, Sakiko, and the one who had a penis in her mouth in the back alley is our manager, Azusa. They’re both my women.”

Masato shrank back at this glimpse into a world unlike anything he had ever experienced before.

Bottles of alcohol lined the interior, and the elaborate decor gave the establishment a luxurious atmosphere.

“This place is what you’d call a secret club. Most of the customers who gather here have various circumstances of their own, but it’s an interesting place. Anyway, you’ve been mistreated by women, haven’t you? If you don’t mind, I’d like to hear the details.”

“U-Um, yes……a-actually……”

Masato decided to tell them everything that had happened between him and the Shinjo sisters.

Throughout his story, the three listened seriously without laughing even once.

“……I see. Just as I thought, you’ve really been put through some terrible experiences.”

Ryusuke seemed to genuinely sympathize with him.

‘He looks suspicious, but he’s actually pretty kind……’

“The more I hear, the more you remind me of my younger self. Maybe I could entrust that to someone like you.”

“E-Entrust……?”

“Those sisters who’ve been tormenting you. Haven’t you ever wanted to get revenge on them?”

“……Of course I have……but there’s no way I could ever actually do it……”

“You can.”

Ryusuke disappeared behind the counter for a moment, then returned carrying what looked like a simple remote control with a button on it, along with a women’s choker.

“This is a hypnosis device. Anyone wearing this choker can be put into a hypnotic state using the remote, allowing you to implant suggestions into them. Once those suggestions become strong enough, they’ll obey commands even without the choker.”

“What!? Th-There’s no way……”

“I’m not lying. Want to see for yourself? ……All right. This is an order. Sakiko, Azusa. Look into my eyes.”

At Ryusuke’s command, Sakiko and Azusa’s eyes became vacant.

‘……Wh-What’s going on? They’ve become almost like dolls……?’

“Lick Masato-kun’s shoes.”

“「「……Yes, Ryusuke-sama……」」”

The two staggered over and knelt at Masato’s feet, then began licking his dirty shoes.

“W-W-Wait!? Huh!? Whaaat!?”

Ignoring Masato’s shock, the two continued thoroughly licking his shoes.

“As you can see. At first, I trained these two using the hypnosis device as well. By now, they’ve become loyal sex-slave pets who obey me even without hypnosis. ……You’d like to make those Shinjo sisters kneel before you like this too, wouldn’t you?”

“Y-Yeah……but I don’t know if I can do it……”

“You can. Those clouded eyes of yours, filled with repression and pent-up resentment──that becomes power for hypnosis.”

With Ryusuke assuring him so confidently, Masato began to feel that perhaps he really could do it.

Then again, that might itself have been the influence of Ryusuke, who was highly skilled in hypnosis.

“……P-Please. Then, let me use the hypnosis device!”

“Yeah, sure. But there’s one condition. Keep me updated on how the training progresses. After all, enjoyment is something meant to be shared.”

“O-Okay!”

“Good. Best of luck.”

And so, through an unexpected turn of events, Masato had reached a turning point in his life.

The next day──.

“What the hell were you doing skipping out yesterday!? Big sis got pissed because you wasted her time and went home ahead of me! I was stuck waiting around the whole time, you know! Seriously, screw you!”

The moment Serina entered the room, she was already furious.

“S-Sorry……I, um……something suddenly came up……”

Yesterday’s choker was hidden beneath the desk, while the remote control was concealed in his pocket.

“Don’t lie to me! You just skipped because you didn’t want to study, didn’t you!?”

“N-No, actually……a friend dragged me along because he was looking for a present for his girlfriend.……And then the store clerk recommended something to me too, so I ended up buying an accessory……”

“Hah!? Are you stupid? A creepy guy like you doesn’t even have female friends, let alone a girlfriend!”

“He-Hehe……y-yeah, that’s true……but, well……this is what I bought……”

Going along with the flow of the conversation, Masato showed Serina the choker.

“Haaah!? Wait, what is this!? This design is totally my type!”

Serina practically snatched the choker out of his hand and immediately fastened it around her own neck.

‘Whoa……I haven’t even said I’m giving it to her yet……’

Still, he had managed to get her to put on the choker without any trouble.

“I’m taking this off your hands! That’ll make up for yesterday, right?”

“Y-Yeah……s-sure……”

While continuing the conversation, Masato pressed the switch on the remote control he had hidden in his pants pocket.

‘……W-Well? Does it really work? This hypnosis device……’

For some reason, the instant he pressed the switch, Serina’s eyes seemed to go vacant for just a moment.

“……H-Hey, Serina-san, don’t kick me anymore, okay? You’re always way too violent.”

“Hah!? That’s only because you’re a worthless piece of trash. You’ve got some nerve talking back after ditching us yesterday!”

Enraged, Serina stood up and tried to kick him with her right foot──.

But her toes stopped unnaturally in midair.

“W-Wait……wh-what the hell is this? Why can’t I kick you!?”

‘The hypnosis really worked!?’

Even Masato himself was shocked that the suggestion had taken effect.

“He-Hehe……you can’t take that off anymore, you know? And if you try to force it off, the choker will tighten and make it impossible for you to disobey me.”

“Hah!? What the hell are you talking about? Something like this──Gueh!?”

Serina let out a muffled cry as she tried to remove the choker.

‘It really is working! Hypnosis was actually real! Amazing!’

Masato was stunned, while inwardly jumping for joy.

“Hehe, hehehe……looks like you can’t disobey me anymore, Serina-san.”

“N-No way, this has to be some kind of trick, right? There’s something weird built into this thing──Gueeh!?”

Serina tried to remove it again but the choker seemed to tighten instantly, causing her to lose her balance and fall back onto the bed.

“Hehehe……how convenient of you to fall flat on your back on the bed for me. Saves me the trouble……”

“Hey, you—enough already! I mean, this is insane! This has to be a dream, right!? There’s no way this is real!”

“Heheh, I thought so too, but apparently it’s reality. Look, from here on, the choker’s just going to keep getting tighter and tighter~?”

“Agh!? Agyuuuuugh!? Nngh, no way…!? Goho, Goho!”

For the first time, Masato was able to see Serina’s face twisted in pain, and an indescribable rush of exhilaration welled up inside him.

“Hehehe…You should pay for treating me like your servant all this time. Starting today, our positions are reversed. I’m the master, and Serina-san is the pet.”

“What kind of creepy crap are you saying!? A gross otaku like you—ugh, gueeh!? N-no, aaah… it’s tightening… If you do any more than this, I-I’m going to die… ah… ngh…”

At last, Serina’s eyes rolled back and she lost consciousness.

“Oops, maybe I overdid it a little. Guess I’ll stop choking her any further.”

After reapplying the suggestion,

“…Fuhah… Haaah… nnah… haaah, haaah…”

Serina was still unconscious but she began breathing again.

However, the area around her crotch gradually became wet. Apparently, she had lost control of her bladder.

“Uwaah… Serina-san, you wet yourself.”

Serina continued urinating as her body jerked and convulsed.

“Come on, that’s filthy. Heheh, well, I guess it can’t be helped…I’ll take those off for you. And while I’m at it… maybe I’ll have my way with you too.”

He pulled off her shorts and moved closer to her exposed body.

“E-hehehehe… Alright, I’m putting it in now… I’m letting you be the one I lose my virginity to, Serina-san, so you’d better be grateful and take my cock!”

Masato then  thrust his penis deep inside her in one go.

‘Wow, incredible!? Her pussy is enveloping me so tightly and tightly!?’

Even though she was unconscious, her body seemed to be responding instinctively to the penetration.

“Nnnnnnnn… nnuh, kuuuh… nnfuu, fuuuh…”

Serina remained unconscious, though her expression had softened from the physical sensations.

“Hehehe, when you’re asleep, you’re actually pretty cute—and a lot quieter too… But seriously, ahh, this feels incredible! It’s squeezing so tightly! Way too erotic!”

Overwhelmed by the unfamiliar sensation, Masato began moving his hips more vigorously.

“Nfuu, aaahn, haahn…!…………Fueh? Eeeeh!? Haaah!?”

Serina’s eyes flew open as the pistoning woke her and she let out a cry of shock.

“Ah, Serina-san, you’re awake? I’m borrowing your pussy!”

“Wha—!? Don’t fuck with me! Why the hell do you have your dick inside my pussy!?”

“Hehehe, this is your punishment for bullying me so much! Come on, come on!”

Masato pressed his weight down over her and began pistoning even more violently.

“Ahh, stop it! Your dick isn’t even worthy of being shoved into my pussy! Hurry up and pull it out, you disgusting virgin! You fucking trash rapist bastard!”

“Shut up! Have you forgotten what happens when you defy me!? Tighten! Choker!”

“Ggyuuugh!? Gahaaaah! I-I can’t breathe…! I-I’m going to die…!”

While choking her neck with the choker, Masato thrust his penis even deeper into her pussy.

“Aghuuuh…!? S-stop already! Don’t put your dick inside meee!”

“I can’t stop myself anymore! I’m going to keep fucking you with my dick! I’m going to cum inside you!”

“Agh, ngh! Y-you… don’t tell me you’re doing it raw!?”

“That’s right! So, how does the raw dick of the disgusting guy you’ve mocked so much feel!? Ora, ora!”

Masato continued pumping his dick in and out with enough force that it was almost like he was slamming his entire body into her.

“Agh! No! Stop it! This isn’t a pussy that a disgusting virgin like you is allowed to stick it into raw! Agh, hagh…! Hiii… stop, enough… ahiii!”

“You can say that, but you’re getting turned on by this virgin dick, aren’t you!? The inside of your pussy is all squelchy and practically flooding! You’re feeling it, aren’t you!?”

“U-ugh, shut up! Don’t just make up whatever you want with your disgusting virgin fantasies!”

“If you resist, it’s the choker for you!”

“Nngyuuuuuu!? Nngi—higii! Agukuu… ugoh, agyuuu!”

As her neck constricted, the squeezing inside her vagina grew even tighter.

Hot love juices began seeping out from deep inside her vagina.

“Uooooh, this gyaru pussy squeezes so hard! It’s way too sexy! Uaaaaah! I wanna enjoy it more, but I’m already about to cum!”

“Hiiiii!? Like hell I’m letting you cum inside me! Pull it out! Pull it out right now!”

Serina screamed with such force that it seemed as though she might shatter the suggestion itself.

However, the negative emotions Masato had accumulated from being treated like her servant for so many years proved stronger.

“Squeeze, squeeze, choker! Kuuuu! It’s squeezing, squeezing so tight! I’m gonna cum inside you!”

“Nngyuuuu!? Aguu! Hyaguu! Nngigi! Hii! Agu! Higii!”

As he thrust his penis back and forth while using the suggestion to constrict her neck, Serina screamed and panted violently.

“Heheheh, Serina-san, aren’t you actually a masochist? Your neck’s being squeezed, yet you’re moaning that much! Uhaaaa! This is turning me on! I wanna cum inside you so badly I can’t stand it! Uaaaaah! I’m gonna cum!”

Savoring the way the folds of her vagina repeatedly clenched around him, Masato slammed his penis in all the way to the base.

As an intense burst of pleasure shot through him, Masato released his semen deep inside her vagina.

“Ahiiiih!? Nooo, you’re cumming inside meee! It’s throbbing—dokun-dokun—inside meee!”

“Uhaaah, that feels amazing! Serina-san’s pussy is squeezing me so tightly!”

As though taking revenge for everything she had done to him until now, Masato kept driving his hips into her with the force of a tackle, continuing to pump semen deep inside her vagina.

“Hiaaah! Aguh, aaaaaah! Stop cumming already! Why the hell do I have to get cummed inside by someone like you!? Die! You fucking piece of trash! You’re so fucking disgusting, you know that!?”

Perhaps the suggestion had weakened along with her climax, because Serina began hurling abuse at him just like she normally did.

“Tch, shut up already. Tighten, choker!”

“Oguh!? Nngyuu!?”

Silencing her by tightening around her neck, Masato resumed thrusting with his still-hard penis.

The pleasure was far too intense for a single ejaculation to be enough.

“Aguh! Nnguh! Nnheeh! Higgiiii!”

“You really are a masochist, Serina-san! Your pussy is happily clenching over and over!”

His semen and her love juices mixed together, producing obscene, sticky squelching sounds with every thrust.

“Ahh, what an incredibly lewd pussy! Your personality is the absolute worst, but your pussy is so filthy and amazing! Hehehe, since I’ve got the chance, maybe I’ll loosen the choker and listen to you whine again!”

“…Goh, geh…! Haa, haa… E-even if you compliment my pussy, it just pisses me off! More importantly, what the hell are you gonna do if I seriously get pregnant!?”

“Heheh, you really hate having me cumming inside you that much? Then say,『Please forgive me!』”

Urging her on as he drove into her with a heavy push, Serina began pleading in a pathetic voice.

“H-hiiii!? F-for… forgiiive me, please forgive meee! I don’t want you to cum inside meee!”

“Oi, oi, hating it that much is pretty rude to me, don’t you think?”

Memories of all the mistreatment he had endured came flooding back, only making Masato even more fired up.

“Agyuu! I already said『please forgive me』, didn’t I!? You piece of trash! You’re the worst! Seriously, just die!”

“Hehehe, that foul mouth is exactly what makes you Serina-san! It actually turns me on even more! In that case, maybe I’ll give you an order this time. Come on, it’s an order! Say,『Please cum inside me!』”

“Like hell I’d ever say something like—uguh!? Eguh!? …P-please cum inside meee!”

Serina looked shocked even as the words came out of her own mouth.

“Hahaha, this hypnosis device really is incredibly effective!”

“Hypnosis device…? Don’t tell me this choker is…!?”

“That’s right! It really helped that you put it on yourself! You’ve been borrowing my game software and manga for years and never giving them back, so you brought this on yourself, didn’t you!?”

Masato continued pounding into her hard, satisfying not only his lust but also his desire for revenge.

“Aguh! Agih, aguu! Nooo! Please, forgive me already! Stop thrusting your dick into meee! Aaaah! No, nooo! Don’t keep going with your dick like that!”

“That’s it! That expression is incredible! That face with pain, pleasure, humiliation, and fear all mixed together! It’s insanely arousing!”

Masato himself had never realized that he could be this sadistic.

It seemed that years of repression and pent-up resentment had nurtured a cruel, sadistic streak within him.

‘Ahh, this feels amazing! I never knew there was anything in life this much fun! Dominating a woman like this feels incredible!’

Feeling a sense of fulfillment unlike anything he had ever experienced before, he continued thrusting back and forth as he approached his second ejaculation.

“Aaaah! No, no, nooo! If you keep doing that…! Hiiii, it feels good! It feels so good! I-I’m gonna lose it! Nnoh, ohooooo! I-I’m cumming! I’m cumiiiiiingーー!”

With neither hypnosis nor suggestion influencing her, Serina screamed those words from the bottom of her heart as she climaxed.

“Uooooooooh! It’s coming! I’m gonna cum so muchhhhーーーー! Uaaaaaaaaaah!”

The inside of her vagina contracted and convulsed wildly.

As he continued pounding into her violently, he released a massive amount of semen.

“Hiaaaaaaaaaah!? Y-you’re cumming inside me againnn! Hiiiiiiiiiiiiーー!?”

“Uoaaah! Amazing! It’s squeezing so tight! Ahh, this feels incredible! I’m cumminggg, cumminggg, cumminggg!”

As he slammed his lower body against hers, Masato climaxed and ejaculated.

The inside of her vagina filled with milky-white fluid, which then gushed back out in large amounts.

“…Hehehe, I really cum a lot… That was amazing, Serina-san. Your pussy felt incredible.”

“…Haa, haa, haa… I-I don’t even know what’s going on anymore…”

“That’s right. You don’t need to think about anything—just become my masturbation sleeve. Hehehe, I’m still nowhere near satisfied. Guess it’s time to keep this revenge session going a while longer.”

“H—!? No… no more, please forgive me…! Seriously, I’m begging you!”

Ignoring Serina as her face twisted in fear, Masato decided to continue satisfying his desires.

Three hours passed before Masato was finally satisfied.

“…Hah… hii… hyuu… hyuu… ah… aaah… akuuu…”

Covered in semen, Serina lay on the bed, twitching weakly.

‘Hehehehe…I cummed so much I’m completely empty now… I never thought the day would come when I could have my way with Serina-san however I wanted…’

Even as Masato basked in the feeling, his mind remained surprisingly calm.

‘That’s right. Since I’ve got the chance, I should record this. It might come in handy for something later.’

Masato raised his smartphone and recorded Serina, her body covered in semen.

“Hehehe… Serina-san, make sure you take a shower and clean yourself up afterward, okay? And don’t forget the morning-after pill. Ah, right. Since we’re here, how about giving me a kiss at the end? If you resist, it’s the choker for you, you know?”

After setting down his smartphone and giving the order, Serina sluggishly pushed herself upright.

“…………U-ugh…………F-fine… I get it…”

Having lost the will to resist from the pleasure and the choking, Serina kissed him of her own accord.

“Mm… nnh, chu…”

‘Serina-san herself is kissing me…! This really feels like a dream…!’

Feeling more fulfilled than ever before, Masato continued kissing her.

★　★　★

The next day. Masato came to the same secret club as before to report on the hypnosis device.

“Welcome. Welcome to Gentildonna.”

Sakiko was behind the bar counter, greeting him with a warm, approachable smile.

“…H-hello… Um, is Otomo-san…?”

“Ryusuke-sama is out on business. He asked me to hear your report in his place.”

“I-I see. U-um… about the hypnosis device, I was able to use it successfully.”

“Oh my, that’s wonderful. Were you able to violate the target female to your heart’s content?”

Sakiko spoke so casually about something so vulgar while smiling brightly that Masato became flustered.

“Y-yes! I-I was able to violate her as much as I wanted!”

“Ufufu♪ That’s wonderful, Shimamura-san. Congratulations.”

Never before in Masato’s life had anyone congratulated him so wholeheartedly for something like this.

“So, Shimamura-san, how exactly did you violate the female? Please, do tell me all about it.”

“Eh? U-um, well, that was…!”

He felt terribly awkward telling a woman in the prime of her life about the intense sex he had had the day before, but keeping his promise to Ryusuke, he properly reported everything they had done during sex.

“My, my, Shimamura-san, you really are something. To get that carried away with your very first hypnosis and even go as far as having choking sex… Ryusuke-sama’s judgment really was spot-on after all.”

Even though he had done something so perverted, being praised for it left him bewildered—and embarrassed in spite of himself.

‘…These people really do live in a crazy world… Wait, I guess I do too now…’

It was something he could never have imagined until just yesterday.

It still felt so unbelievable that he wondered if he was dreaming.

“Ufufufu♪ Ryusuke-sama also entrusted me with some other hypnosis devices. Please make good use of these earrings and this hair clip. These earrings are effective not only for hypnosis, but also for『common-sense alteration』while this hair clip makes『psychological alteration』easier to induce.”

“Eh!? Is it really okay for me to have these!?”

“Yes. The other female…her name was Haruna-san, wasn’t it? She seems like she’ll be quite difficult to deal with, so I think it might be a good idea to try both types of hypnosis on her. Once her conditioning has progressed to a certain extent, she’ll start obeying you even without wearing the devices, so do your best.”

Sakiko even offered him advice, smiling cheerfully the whole time.

“Th-thank you very much! I’ll do my best!”

“Ufufu♪ It’s nice to be young. I’m looking forward to seeing your results.”

Sakiko placed the earrings and hair clip into a paper bag and handed it to him.

After leaving the club, Masato walked through the city while thinking over his plans from here on.

‘…The problem is whether I can get the hypnosis device onto Haruna-san without any trouble…’

Compared to Serina, Haruna was much more wary. He felt that he would need to come up with some kind of plan.

‘…That’s it. I’ll make Serina-san help me…! Umm, the karaoke place she said she works at should be somewhere around here, right…?’

Masato remembered the location of the karaoke place Serina had mentioned before and headed there.

“Welcome—… Eek!?”

Serina was alone at the reception desk, but the moment she saw Masato, her face went pale.

The choker was still fastened around her neck.

‘Hehehe, just as I thought, the suggestion is still working…’

“Y-you… Why are you—”

“Ah-ah, no unnecessary chatter. Give me one of the rooms in the back. And bring me some oolong tea too.”

“…Y-yes, sir.”

Under the power of the hypnosis, Serina obediently nodded.

‘Heheh, the power of this hypnosis device really is overwhelming…’

Satisfied by the resentful glare Serina was giving him, Masato went into one of the private rooms in the back.

After sitting down and waiting for a little while, Serina came in carrying the oolong tea.

“Thanks. Just leave the oolong tea on the table. More importantly, I’d like you to get me off with your mouth.”

“Hah!? What the hell are you talking about!? There’s no way I can do something like that at work—”

“If you don’t do as I say, I’ll choke you. And this isn’t a request—it’s an order, okay?”

“Higuuuu!? F-fine, I get it, I get it…! I just have to suck it, right!?”

The choking must have been extremely harsh. Serina reluctantly agreed, sounding almost desperate.

“What’s with that attitude? You’re a pretty lousy employee. Do it over. Try begging me yourself to let you give me a blowjob.”

“Kh… f-fine… Let me give you a blowjob.”

“Nope. There’s no feeling behind it. Thirty points. Do it again.”

“…U-ugh… I-I want to suck it…! Your dick… I want to use my mouth to… m-make you feel good!”

By the end, she was practically shouting it out in desperation.

“Yeah, well… I guess I can give that about seventy points. All right, then. I’ll let you suck my dick. You should be grateful, okay?”

Masato deliberately took his time as he pulled his dick out of his pants.

“Come on, hurry up and crouch down. Put my dick in your mouth.”

“Kh…th-then… please allow me to… suck your dick…!”

Even with disgust, embarrassment and humiliation plastered across her face, Serina obeyed the order and took the penis into her mouth.

“Nmuu… nchuu… ugh, what is this… it stinks…”

“Oi,oi, complaining the moment you put it in your mouth? You’ve got some nerve. Do you have no ability to learn?”

When the suggestion caused the choker to tighten more and more around her neck, Serina hurriedly latched onto his penis

“Nguu, njuu, jupo!”

“That’s right, just like that. Instead of wasting your breath talking, all you need to do is suck my dick. Ahh, it’s warm and your tongue is nice and rough—it feels so good. What a nice mouth-pussy.”

“Nnghhh…”

Even while glaring up at him resentfully, Serina continued bobbing her head up and down as she gave him a blowjob.

“Ahh, using a mouth feels pretty damn good too. It has a different kind of slimy, slick sensation compared to a pussy.”

That hateful mouth which had hurled abuse at him so many times before was now practically nothing more than an onahole.

“Ahh, come on, take it deeper. Use your tongue too.”

“Nguuuu! Njichuuu! Nchuku, churuuu…chapu, chupaaa!”

Perhaps because she was a gyaru, she seemed to have plenty of experience and her technique was surprisingly good.

The entire length of his penis was being stroked by the hot mucous membrane of her mouth, while her saliva coated it just right.

Her tongue brushing against him at irregular intervals produced an indescribable pleasure.

“Hehehe, so how does my stinky dick taste? You sure look like you’re enjoying it, don’t you?”

“Uguchu, churuuu…! Euh, ugweh, rero, chupu, picha, chupaaa!”

From the tears welling in her eyes, he could easily imagine that it tasted awful.

But seeing an expression like that only stirred his sadistic urges even more.

“Come on, drink my juice! That’s an order!”

“Nnnn!? N-no, stop! Nngh!? Gogk, gulp! Ngueeh!?”

Serina tried to resist but she was unable to defy the powerful hypnosis.

Her throat bobbed as she swallowed down the saliva-filled smegma-mixed juice.

“Hahahahaha! Pretty rich, wasn’t it? Actually, I didn’t take a bath yesterday. Which means some of your own dischar

“Hahahahaha! Pretty rich, wasn’t it? Actually, I didn’t take a bath yesterday. Which means some of your own pussy juice from yesterday was still on there too, you know? And then there was my semen! Top-quality stuff, right!?”

Letting out a wicked grin, Masato began thrusting his hips as well.

“Nguuu!? Njuzuuu!? Ngo!? Ngubu! Njubuuu! Jubuzuuu!?”

“Hahahaha, this is great! Violating your mouth feels amazing too! What an incredible feeling!”

As if taking revenge for all the humiliation he had suffered, he began forcefully irrumating her.

“Come on, move your head yourself too! Serve me! If you don’t, I’ll choke you!”

Under the strong hypnotic command, Serina also began moving her head vigorously on her own.

“Juboo! Juboo! Jubo! Juguh! Jubobo! Juzubuu!”

The amount of saliva increased even more, leaving the inside of her mouth covered in sticky fluid.

The heat and pleasure doubled, surging even higher.

“Oooh! Amazing, amazing, Serina-san! You really are a mouth-pussy slave! This is the best! At this rate, I might just have to give you a perfect hundred points!”

As he continued grading her blowjob, he sped up his thrusts, driving himself closer to ejaculation.

“Nguuu! Njubu! Jubojubu! Juguru! Jubu! Juguuu!”

Serina hollowed her cheeks and sucked tightly, making sure his dick did not slip out of her mouth.

“Uaaah! Damn, you’re so lewd! Gyaru have the worst personalities, but when it comes to sexiness, they’re the best! You really are excellent as an onahole slave!”

As he continued, an overwhelming urge to ejaculate surged up inside him.

“All right! Then I’m going to unload plenty inside your mouth and make you swallow it, Serina-san! Come on, beg me for it yourself!”

“Nn, mpuaaah! P-please cum! Please cum! Inside my mouth! Please fill my mouth with lots of semen!”

Serina instantly obeyed the hypnotic command, briefly pulling his penis out of her mouth as she pleaded with him.

‘That damn cheeky Serina-san is doing absolutely anything I tell her to!’

Once again overwhelmed by the power of hypnosis, his pleasure rose to its absolute peak.

“Uwaaaaaaaaaaaaaah!”

As his vision went completely white, Masato ejaculated while thrusting his lower body against Serina’s face.

“Nnguuuuuuuuuu—! Njugu! Jujyuuuuuuuu—!”

Semen burst inside her mouth. Pleasure exploded through him.

But Masato had no intention of stopping there.

“After cumming inside your mouth, next comes a facial!”

He forcibly pulled his penis out of her tightly sucking mouth and this time showered her with semen.

“Nbuuh!? Nnyaaaaaaaaaah! It’s hot! Nooo! It’s filthy!”

The white semen stood out vividly against the gyaru’s dark skin.

“Fuhahahaha! It suits your skin really well, Serina-san—semen milk!”

“Nooo! Aaaah! It stinks and it’s all thick and slimy! W-why is there so much of it!? Fuaaaaaah!”

Serina’s whole body trembled and twitched as she was helplessly smeared white.

“Phew… hehe… Man, that was a lot~. I thought there wouldn’t be that much left after how much I came yesterday, but I guess I was wrong. I’m surprised myself.”

“Uuugh… m-my whole face is completely covered in semen…! I’m in the middle of my shift—what am I supposed to do now!?”

“Hehehe… Well, it’s only your face and mouth, so you’ll probably manage somehow, right? More importantly, give me a cleanup blowjob. I’ve always wanted to try that at least once.”

Since he had the chance, Masato decided to indulge every one of his desires to the fullest.

“Y-you… just you wait… nchuru, chupa, rero, reron, rerooo.”

Overcome by her fear of the choker, Serina voluntarily ran her tongue along his penis, licking it clean.

“Ooh, it tickles a little, but it feels good, Serina-san! Man, I never thought the day would come when I’d have you giving me a cleanup blowjob~. The master-servant relationship has completely flipped, huh?”

“Uuugh… how did things end up like this…? This is a nightmare… chu, chuuu…”

Even with tears in her voice, Serina latched onto the head of his dick and sucked out even the semen remaining inside his urethra.

“Heheh, that’s it, Serina-san. If you hate being my toy that much… how about helping me corrupt Haruna-san? If you do, I might consider taking the choker off.”

“Eh!? Really!?”

“Yeah. I want to turn Haruna-san into my toy too, after all.”

“I’ll do it, I’ll do it! I don’t care what happens to my big sis!”

Serina answered immediately without the slightest hesitation.

“Hahaha, Haruna-san got sold out by her own little sister just like that. Guess she’s not very popular, huh?”

“B-because! Sis works people way too hard! And she’s so overbearing!”

It seemed the two of them got along even worse than Masato had expected.

‘..Well, they’re both selfish, after all…’

But thanks to that, it seemed like he might have found an opening for getting to Haruna.

“Fufu, then I’ll be counting on your cooperation tomorrow.”

“F-fine…”

Serina picked up the oshibori she had brought along with the drink and answered while wiping her face.

[An oshibori is a warm or cold damp hand towel given to customers in Japanese restaurants, inns, and other hospitality settings to clean their hands before a meal]

The following day, during Masato’s private tutoring session—

Haruna cast a suspicious look at Masato as he worked through the problem set.

“…This is unusual. You’re actually studying seriously. …It’s creepy.”

“He-heh… Even I have days when I feel motivated.”

Serina was also sitting beside Haruna.

‘She’s suspicious, but I’ve just got to push through this. I’m counting on you, Serina-san!’

Masato glanced over and gave her the signal. Serina began fiddling with her hair before speaking up.

“Ah, um… by the way, you… aren’t you going to give Sis that thing? You know, the apology gift for the day you ditched us.”

“R-right! Haruna-san, I’m sorry about the day before yesterday! I ended up skipping my studies!”

“Huh? …Oh, you mean that day you bailed? I thought I left it to Serina, though…”

“Ah, yeah! I got an apology gift too! Look, Sis! This choker suits me, right!? He got dragged along by a friend and ended up buying accessories! What an idiot, right!? He doesn’t even have a girlfriend, let alone any female friends!”

Serina showed off her own choker as if to emphasize it, wearing an awkward smile.

“Hmph… You accepted an accessory from someone like him?”

“Ah, haha…At first I thought about throwing it away, but once I looked at it, it actually seemed pretty nice. I mean, the quality seems good, you know?”

“Hmmm…? …Oh, it actually looks better than I expected…”

After looking at Serina’s choker, Haruna seemed to show at least a little interest.

‘Haruna-san is a tough one, but I have to make the most of this chance…! And I’ll definitely turn her into my sex slave!’

With firm resolve, Masato began putting on a servile act.

“He-hehehe…W-well… there’s no point in me keeping it anyway…and Haruna-san has looked after me for a long time… so, if this could maybe persuade you to go a little easier on me…”

Masato held out a boxed pair of earrings from beneath the table.

“Seriously, what’s gotten into you? You’re being really creepy…”

‘…As expected, she’s not going to accept them that easily… She really is a formidable opponent… Haruna-san seriously has that final-boss vibe…’

That was when Serina made her move.

“Hmm~? Sis, you don’t want them? Then I’ll just take those too, okay~? They actually seem pretty nice. Ehehe, lucky me!”

“Wait.”

Haruna stopped Serina as she reached out and snatched the earrings first.

“Sis!?”

“I suppose I’ll accept them. They do seem to be of decent quality, after all.”

‘Nice acting, Serina-san!’

Apparently, as the domineering older sister, she simply couldn’t stand the thought of her younger sister getting something instead of her.

It was a fine play that turned her nasty personality against her.

“Hmph. Earrings like these suit me much better than they suit you.”

Then, as if to assert that they now belonged to her, Haruna immediately began putting the earrings on.

‘She dug her own grave! Well, she brought it on herself!’

Her nasty personality and spitefulness were what sealed Haruna’s fate.

“Ahh, that’s right! Now that I think about it, my friend asked me to come out today! Sorry, Sis, I’m heading out for a bit!”

“Huh? Hey, Serina?”

Serina deliberately raised her voice as she stood up and left the room.

‘Hehehe… Good job, Serina-san! Leave the rest to me.’

Masato pumped his fist inwardly.

“Serina was acting strangely… and so are you…”

Haruna gave him a suspicious look.

‘Eek…! Haruna-san really isn’t someone you can deal with easily… I need to settle this quickly.’

Masato pressed the button on the remote control he had hidden in his pocket.

‘Please! Work, hypnosis device…!’

He looked at Haruna as though praying.

“…Eh…? Ah…? W-what is this… strange feeling…?”

Haruna’s eyes wavered, gradually losing their light.

Then she froze in place, almost like a doll.

‘Looks like it’s working…? All right, let’s test it…!’

Masato swallowed hard and steeled himself.

“H-Haruna-san… umm… c-could I… touch your breasts for just a little bit?”

If she had been in her right mind, she would have immediately knocked him flying, but—

“………………Sure………………”

Haruna, her eyes vacant, gave him permission.

‘It worked! Haruna-san actually fell under hypnosis!’

Feeling as though he had just defeated the final boss in a game, Masato reached toward Haruna’s enormous breasts. Spreading his fingers wide, he firmly grabbed one of them.

‘Wow… I knew they were huge, but this is incredible…!’

Her breasts were so full and voluminous that they seemed to spill out between his fingers.

And yet, they were so soft that his hands seemed to sink right into them.

“He-hehehe…Haruna-san’s breasts… They’re really Haruna-san’s breasts…!”

Reassured that the hypnosis was working, Masato boldly began kneading her breasts.

“…Nn… nnh, fuu… nn… nnh…”

Before long, sensual breaths began slipping from Haruna’s lips.

“All right, all right. Since I have the chance, I might as well implant a suggestion too. …Haruna-san, from now on, whenever you’re together with me, anything I say is 『common sense』will become common sense to you too, okay?”

“…………Y-yes……… Anything Masato says is common sense will become common sense to me as well…………”

“No matter how lewd it is, you won’t question it.”

“…Even if it’s something lewd, I won’t question it…”

Haruna repeated Masato’s words, engraving the suggestion into her own mind.

“O-okay… then you can go back to acting like you normally do. But you’ll obey my『common sense』 properly.”

“…Yes… understood…”

The light gradually returned to her eyes, and Haruna reverted to her usual arrogant and overbearing demeanor.

“Huh…? What was I…? Wait, why are you slacking off on your studying!? I never said you could stop working! At least do the damn problem set properly, you loser!”

She furrowed her brows in irritation and hurled abuse at him.

‘Heheh, then let’s try out this『common-sense alteration』!’

It seemed more difficult than ordinary hypnosis, but that only made it more worth trying.

“Umm, Haruna-san… when you can’t solve a problem, it’s『common sense』to calm yourself down by fondling your private tutor’s breasts, right?”

‘…Well…?’

Masato swallowed nervously and watched Haruna’s reaction.

“…………That’s right. Of course it is. I can’t believe I forgot something like that.”

“He-heh… Exactly. Forgetting something this obvious isn’t like you, Haruna-san… Well then…”

Satisfied that the『common-sense alteration』had worked, Masato began kneading her breasts again.

“…Nn, nnh… Don’t be so rough… You’re supposed to massage breasts gently, lifting them as you do it, okay?”

“Sorry, sorry… Man, Haruna-san, your breasts really are huge… What size are these?”

“W-why do I have to tell you something like that?”

“Because it’s common sense for a private tutor to honestly answer her student’s questions, right?”

Haruna gave a visible twitch at the word『common sense』coming from Masato’s mouth.

The effect appeared to be tremendous.

“…Y-yeah, if it’s common sense, then I have to answer… 110 centimeters… K-cup.”

“K-cup!? Even among gravure idols, you hardly ever see someone that size!”

“Hmph. I don’t have a body that would lose to some mere idol.”

Haruna proudly puffed out her chest, though depending on how one looked at it, the sight was almost comical.

‘Hehe… Haruna-san has a weirdly strong sense of pride about certain things, so maybe this common-sense alteration is especially effective on her.’

Feeling that he had gotten the hang of it, Masato decided to create another piece of common sense.

“Oh, right, Haruna-san. It’s common sense for a private tutor to masturbate during the waiting time and kill time by showing it off to her student, right? Don’t tell me you forgot?”

“…Eh…? R-right, of course I haven’t forgotten! It’s a hundred years too early for you to make a fool of me!”

Getting worked up, Haruna began rubbing her clitoris through her underwear.

“Ohh, so you’re the type who starts with your clitoris , Haruna-san.”

“I-it’s not like there’s anything strange about that. You just know way too little about women! Plenty of women prefer the cclitoris!”

Haruna snapped angrily, then, as though determined to prove her point, deliberately exposed her crotch toward him and began vigorously rubbing her fingers up and down.

“Ohh, amazing, Haruna-san! So that’s how you masturbate!”

“Hmph. You should be grateful. Normally, you’d never get to see this!”

Even as Haruna spoke as though she were doing him a favor, she continued diligently moving her fingers in accordance with the fabricated common sense.

“Ahh… nnah… ah, I’m coming… nnnngh…!”

“Eh!? Aren’t you coming way too fast!?”

“Shut up! Could you not criticize someone else’s masturbation!?”

“Sorry, sorry. Then go ahead and keep going until you come. Hehehe.”

With a vulgar grin on his face, Masato at least pretended to work on the problems.

“Because of you, I missed my climax. Honestly… This time, I’m doing it directly.”

Haruna slipped off her panties, exposing her neatly groomed, beautiful slit.

“Ohh, amazing, Haruna-san! I thought it might be dirty from getting so much use, but it’s not like that at all.”

“Don’t go spouting nonsense. How much it gets used and how clean a vagina looks don’t necessarily have anything to do with each other. You really don’t know anything about women, do you!?”

While lecturing him about the female body, Haruna began running her fingers up and down along her wet slit.

“…Nnnh, fuu… haaah…”

‘Who would’ve thought the day would come when Haruna-san would masturbate right in front of me… And those finger movements are pretty erotic… Could she actually be quite the masturbator?’

Thinking that, Masato decided to ask her right away.

“Haruna-san, about how many times a week do you masturbate?”

“You’ve got some nerve asking a woman something like that. That’s seriously creepy.”

“But it’s common sense to answer when your student asks you something, right?”

“…R-right, that was common sense… I do it about four times a week…Masturbating and getting refreshed is good for your beauty too.”

Even when asked something extremely private, Haruna answered him honestly.

“I see. Masturbating that often even though you have a fiancé… You really are pretty horny, Haruna-san.”

“Sex and masturbation are separate things. Honestly, this is why virgins are hopeless…”

‘…Heheh, I already lost my virginity to your little sister Serina-san, though…’

Once again, Masato felt a deep sense of satisfaction from having the Shinjo sisters, who had always treated him like a servant, now doing exactly what he wanted.

‘Hehehe… My reversal of fortune and revenge have only just begun!’

Haruna gave him a suspicious look, but her fingers never stopped masturbating.

“Haruna-san, make sure you show me properly when you come, okay? I don’t really understand women that well, so I want to learn from watching you masturbate.”

“Honestly, you’re hopeless. Bad at studying and unpopular with women too… How pathetic.”

‘Hehehe, the pathetic one is Haruna-san, who’s become my toy… Oh, right!’

Masato picked up his smartphone, switched it to recording mode and pointed it at Haruna.

“Hey, what the hell are you doing!?”

“Well, I figured I should review it later so I can study the female body properly. Recording something like this to learn from it is common sense too, right?”

“…Y-yes, that’s right… It was common sense…”

It seemed to put a little strain on her, but apparently she accepted it.

“Then, Haruna-san, while you’re at it, put your fingers inside and come while rubbing your G-spot.”

“O-okay…Make sure you watch properly… Nnngh! Haaah!”

Haruna inserted her fingers into her vagina, curled them, and began stimulating the sensitive area.

“Ohh, amazing, amazing. So that’s around where the G-spot is.”

“Honestly, virgins really don’t know anything. Knowing the name but not even knowing where it is…Nnngh, haaah, aaah, nnah, kufuuu!”

Each time her fingers thrust in and out, a wet jupu-jupu sound echoed.

“Haruna-san, you get wet pretty easily, huh?”

“This much is normal. Nnnh, aaah, this feels good… I’m feeling it even more than usual! Masturbating while being filmed feels good… it feels so good! Nfuu!”

The wet sounds coming from inside her pussy grew louder and more intense.

“Ohh, that’s way too erotic, Haruna-san. Come just like that! Show me when you come!”

“Aah! Haaah! Fuuuh! I-I’m coming! I’m coming! I’m cummiiiiing—!”

Haruna’s entire body convulsed violently as she climaxed.

At the same time, a clear jet of fluid burst from deep inside her pussy.

“Oooh! So this is what squirting is! Amazing! That’s amazing, Haruna-san!”

“Nhooooh! I’m cumming, I’m cumming, cumming, cumming, cummingggggg—!”

Haruna continued spraying fluid as she violently rocked her hips back and forth.

Perhaps because of her queen-like personality, even the way she climaxed had an overwhelming presence to it.

“Wow, that was incredible, Haruna-san! You really went all out!”

“Y-you’re such a hopeless virgin, so I’m properly teaching you, aren’t I!? Ooohooooh! No, this feels completely different from usual—it feels way too goooood!”

‘She normally acts like such a coldhearted queen, but when things turn sexual, she completely loses control, huh…’

The sheer contrast turned Masato on as well.

“Man, there really are tons of things you can’t learn just by solving problem sets! If I hadn’t seen it live like this, I never would’ve known just how intense a woman’s masturbation could be!”

“Haa…haa…haa…♪ S-see? That’s right! Seeing something once is worth hearing about it a hundred times!”

“Hehehe, that’s pretty convincing. Your squirt even reached all the way over here. Seriously, you showed me something great! I learned a lot!”

“H-hmph… Well, I suppose it was worth going this far to teach you.”

Haruna did not seem entirely displeased by Masato’s praise.

She then straightened out her disheveled clothes and returned to her usual appearance.

‘Now then, since I’ve got the chance, I might as well try out the other hypnosis device too.’

Masato took the hair clip out from beneath the table.

“Hey, Haruna-san… Actually, I have one more present for you. It’s common sense to accept a gift from your student, so go ahead and put it on right away. And after you put it on, take off the earrings.”

“Oh, there’s still more? You really need to fix that habit of wasting money.”

“Hehe… Well, this isn’t really a waste… Anyway, just try putting it on.”

“Fine.”

Haruna put on the hair clip and removed the earrings.

At that moment, Masato pressed the button on the remote.

‘All right, this time it’s『psychological alteration』! Let’s see…’

He hurriedly thought up the suggestion he wanted to implant.

“Haruna-san, listen carefully. Whenever it’s just the two of us, you’ll feel an overwhelming urge to pamper me and treat me gently.”

“…Pamper you… treat you gently…?”

“That’s right. Instead of acting rough like you usually do, you’ll let me depend on you. And whenever I ask you for something, you’ll desperately want to do whatever I ask, no matter what it is, and whenever you grant my request, you’ll feel deeply satisfied. Oh, and call me『Maa-kun』, okay?”

“…All right.”

Even Masato himself thought it was a pretty high-level suggestion.

‘I wonder if Haruna-san, that tyrannical queen, will really pamper me…?’

His heart pounding, Masato decided to speak to Haruna.

“Um, Haruna-san…”

“What is it, Maa-kun?”

‘Ooooh! Haruna-san actually called me『-kun』!’

A different kind of excitement from when he had watched her masturbate earlier welled up inside him.

“U-um, Haruna-san… I don’t understand this problem. Could you teach me…?”

“Of course. Maa-kun, which part don’t you understand?”

Haruna moved over beside him, leaned in close, and kindly helped him with his studies.

‘Uwah, she’s like a completely different person! But this contrast is irresistible! I could actually work hard at studying like this!’

In her gentle big-sister mode, Haruna was also very good at teaching and Masato breezed through the problem set he had been struggling with.

“Oh my, you got every single one right! You did a great job, Maa-kun♪ Such a good boy♪”

Haruna even gave him a warm, motherly smile as she hugged him.

‘Heheh! Her breasts are pressing right against my face and it feels amazing! Ahh, I can’t get enough of this!’

His dick grew harder and harder until he could no longer hold himself back.

“…U-um, Haruna-san. Isn’t there some kind of reward for getting every question right? L-look… my dick is this hard already…”

Masato naturally exposed his penis as though it were the obvious next step.

Normally, she would have knocked him flying but Haruna was deeply immersed in the hypnosis.

“Oh my, Maa-kun, you’ve gotten so big. Fufu, I suppose it can’t be helped since you’re a boy at that age. Then maybe I’ll give you a special reward and give you a handjob?”

“Th-thanks… Then I’ll leave it to you… Hehehe…”

“Fufu, what an impressive dick you have♪”

Her voice cheerful, Haruna gently wrapped her hand around his penis and began stroking it up and down.

“Uah, haaah! That feels good, Haruna-san! Your handjob feels amazing!”

Haruna moved her hand with practiced ease.

‘C-could it be that she always does this for her fiancé?’

Just thinking about that made him feel jealous.

“Here we go, stroke, stroke~♪ You did such a good job finishing the whole problem set. Such a good boy, such a good boy~♪”

“Uaaah! It feels so good when you keep changing the pressure as you stroke it!”

And the unusually sweet tone of her voice was such a stark contrast from her usual self that it excited him even more.

‘Damn it… It pisses me off, but I guess having a fiancé is probably why her technique has gotten this good.’

He had somewhat mixed feelings about it, but there was no denying how good it felt.

“Fufu, Maa-kun’s balls are so big and heavy♪ They look like they’re packed full of semen♪”

“He-heh… I’ve always been pretty confident about how much I ejaculate.”

“Oh my♪ Then I’m looking forward to it♪ Maa-kun, make sure you shoot lots and lots for me♪”

Smiling, Haruna began speeding up her handjob.

Her movements were rhythmic, driven by sharp flicks of her wrist.

“Uoooooh! Amazing, amazing, Haruna-san! Kuuuh!”

“It’s your reward, so you can let out as much as you want♪”

“Yeah, I’m cumming! I’m gonna cum from your handjob, Haruna-san! Uhaaaaaaaaaah!”

Masato roared in ecstasy as a huge amount of semen spurted out like a fountain.

“Kyaaaaaah♪ Amazing, amazing, Maa-kun♪ You did such a good job letting it all out~♪”

“Aaaaah! Haruna-san! I did it! Uhaaaah!”

The perverse play of being praised for ejaculating caused even more semen than usual to keep spurting out.

‘He-hehehe… The hypnosis device really is the best…! I can’t believe it can change Haruna-san, with that awful personality of hers, this much.’

“Oh my, my, you let out so much♪ I’ll make sure to wipe you clean♪”

Watching Haruna even take care of the cleanup afterward, Masato felt a sense of satisfaction unlike anything he had ever experienced before.
