The instant Sunou matched eyes with me, she roused her body in an attempt to escape.

“It’s pointless. [The Rule is Easy].”

I immediately stated the suggested key word.
Sunou’s resistance was fruitlessly made powerless as her eyes glazed over on the spot.

“……”
“Now, Sunou. From now on, you will be tied up. Right now, Sunou is being tied up by invisible chains.”
“……tied up.”

Upon implanting this suggestion unto Sunou, both of her hands were suspended in the air, as though they were tied up by chains.

“And I have restrained you in the position which you believe is the most embarra.s.sing. There now, the chains’ shape transforms as you steadily change into an embarra.s.sing position.”
“……embarra.s.sing……position.”

While blus.h.i.+ng slightly, Sunou brought both of her hands, which were hanging up in the air, and folded them behind her back as though to show off her sides. She spread both of her feet wide so that I could clearly see her crotch, causing me to lay my eyes upon her damp underwear.

“Those chains cannot be removed until you have s.e.x with me.”
“s.e.x will……remove.”
“Now then, your consciousness will gradually move upwards and you will awaken. Let’s walk up 10 steps of stairs……one step.”

Anyway, this should be all that I need to do.

“10 steps, ok!”
“……huh? Ah……aaahh!! What’s this!?”

Having regained consciousness, Sunou checked her current appearance. Despite shaking her body from side to side, she was unable to break her current pose.

“Let go of me! For what reason is-”
“You cheated, didn’t you?”
“Hehh!?”

She raised an easy-to-understand squeal. She immediately came to a realisation.
She’s even useless in this area. She lacks sophistication as her feelings of guilt came to the fore.

“The cheat was forging my name. Well, I knew it from the beginning, though.”
“Then why bring it up now?”
“At first, I wanted to give you my praise. It’s fine if you cheat. However, it will be the end if it’s discovered. Cheaters won’t cheat if they know they’ll be discovered. If they aren’t discovered, then they should conduct themselves appropriately.”

Approaching Sunou’s body, I stroked her chin with my fingertips.
Sunou couldn’t resist as all she could do was turn her face away in displeasure.

“But, well, I thought that I should praise you. That’s why I’ll end it without having you suffer so much—-”
“You’re going to do it either way, aren’t you, you demon! You don’t intend to study seriously at all!”
“Naturally. Don’t tell me you only realised it now?”

Although slight, Sunou has gained a little bit of resistance, huh. Having been violated countless times, she probably became accustomed to it.
Thinking this, I changed my mind.

“As I thought, I should discipline you, huh……Kokoro.”
“What!?”
“That’s no good, Sunou-chan. You need to properly make preparations to be ravaged by Master.”
“Kokoro-nee-san!?”

Having awakened and risen to her feet, Kokoro began to stroke Sunou’s restrained body.
Sunou’s body reacted with a *twitch* from just this, but she naturally wasn’t able to climax.

“Ah……aah……”

The frustrating pleasure ran around Sunou’s body. As long as I don’t touch her, her libido which could not be released would acc.u.mulate up until the utmost limits.

“Heheh……Sunou-chaaan.”

Waking up, Mai also began to fiddle with Sunou’s body.

“Mai-san, why!?”
“This is a study session……I need to help out.”
“This is a study on endurance, as well as how to avoid a crisis situation. It can also be said that it’s a lesson on how to cope with rape.”
“What’s with that……hyah!?”
“Then, let’s do it……kay?”
“No, Mai-san, that’s-aaahh!”

Mai forcibly pushed her finger through Sunou’s b.u.t.t hole.
Kokoro carefully and steadily gathered pleasure into Sunou’s v.a.g.i.n.a, stripping away Sunou’s reason.

“Ah, demon! If you want to do it, then you should just do it! I already give up, so!”
“I refuse.”

There’s no way that I’d find it fun if she said such a thing as though she were making a compromise.
From the bookshelf in the room, I took out an appropriate book and started reading it. It seems like this is going to take a while.

From my point of view, that remark was a clump of pride. I think that Sunou’s way of living where she keeps true to herself is really wonderful.
But, sometimes, there’s a need to deceive people on the surface. There’s no future growth for people who maintain unnecessary obstinacies and let opportunities escape.
I’m trying to teach her how she, [alone], can survive in a world where one can only live by themselves—in a world with true human relations.h.i.+ps, of which has no rules.

“W-What are you doing!? If you want to ravage me, then-hyaahh!!”
“Hey, hey! What’s happening here? Somehow, it’s really squishy.”
“S-stop, Mai-saa……aaaahnn!! S-Stop!”

Despite Sunou protesting with watery eyes, Mai showed no sign of stopping.

“Even though it’s this small, to think that it was able to swallow Master’s member whole…..no, it probably hurt, so I’ll have to widen it.”
“Ah, hyaaahh……!”

Kokoro was also merciless. Her fingertips, which were more skillful than mine, further loosened Sunou’s sopping wet v.a.g.i.n.a.
Each time Sunou tried to bend her body backwards in climax, she returned to her original position as though she had held down a sneeze.

“W-Why can’t I……c.u.m!? Why is it stopping!?”

Squirming her body, Sunou struggled desperately to attain pleasure on her own.
I found the appearance of Sunou, shedding tears because she was unable to gain pleasure, irresistible.

“There, isn’t it painful, Sunou-chan? You need to properly tell Master.”
“I need to tell–wait, stop! Aaaah……ah, don’t stop! I’ll go crazy!!”
“With that att.i.tude, Master will go home, you know. Children who don’t properly beg for it will-”
“No, don’t go home!!”

Kokoro’s gaze turned towards me. It’s likely because she began to feel pity for Sunou.
Shaking my head as though saying that it still wasn’t good enough, I stood up.

“Sunou.”
“Ah, eh, demon……”
“I’m gonna fondle you.”

Extending my index finger, I placed my fingertip against Sunou’s throat.
From there, I moved my finger straight down, tracing straight in the centre as though to caress her. From her throat to her chest, from her chest to her navel, and then down to her abdomen.

“——————–!!!! Kah, -ah!”

With a *twitch*, Sunou broke out into convulsions in response to such light stimulus. She opened her mouth wide, extended her tongue as saliva dripped out.
Just like that, I slowly advanced, stopping at a spot where I almost, but didn’t touch her c.l.i.toris.

“–hhaahh!! Haahh……haahh……”

Having thrust her hands forward and her body arched backwards, Sunou lifted only her neck as she stared at my finger.
She directed her feverish gaze towards that finger, as if saying that this was a first cla.s.s dish.

“Are you fine with this?”

I shamelessly spat out.
Sunou understood. This finger wasn’t enough. What she really wanted wasn’t something like this.

At that point, I finally sent a gaze towards Kokoro.
Finally making a relieved expression in response to this, she whispered into Sunou’s ear, whose consciousness was vague.
I wonder what she’s saying to Sunou? However, it’s likely that her head can’t do anything except try to execute its contents.

“……I-I can’t bear it anymore. Please plug up my small, lewd p.u.s.s.y.”
“Is that it?”
“I-I’ll do my best to take it all in! So that you’ll be satisfied with my small p.u.s.s.y—so that c.o.c.k-sama will be satisfied! I’ll do my best so that your seed will come out, sooo!!”

Sunou’s cry that bordered along desperation, along with her demeaning line, reached my ears.
It’s likely that the pride inside of her has already collapsed.

“Well, you get a pa.s.sing grade.”

I closed the book I held with one hand and placed it on the floor, taking out my p.e.n.i.s without any preface as I inserted it into Sunou.

“Agggh, aaaaaaaaaaaaaaahh!! Itchs heaaaaaaaaaaaahh!!”

The moment it entered, Sunou’s suggestion was lifted as her body became free.
With her body, which regained its freedom, Sunou moved both of her legs and crossed them around my waist. She desperately clung to me so as to ensure that we wouldn’t separate.
Just as she declared earlier, it means that she’s trying her best to eat it all up.

“Aaahh, haaaaaaahh!!”

It’s likely that Sunou headed towards climax at the moment of insertion. The dam which held back the stimulus was destroyed, swallowing up everything.
Trying to piston, I forcefully drew back my waist. In doing so, Sunou placed strength in both legs, drawing me closer so as to not let me escape.
As a result, the piston which had more power than usual spread out the insides of Sunou’s v.a.g.i.n.a.

“Agah, aaahnn!! Nnnngghh!!”

I covered Sunou’s mouth, which was hanging open like an idiot, with my own. I playfully drove my tongue into her throat, pouring my spit into it.
In the face of this moisture, Sunou discharged more tears and filth.

“Nnnnngh! Nng buhggghh!!”

It would seem that Sunou was able to obtain pleasure from the stimulus that came from her mouth. In the face of the billows that came from both above and below, her eyes were no longer able to maintain their focus.
She almost doesn’t have her consciousness anymore. Even though she wasn’t able to muster strength in her entire body, only her legs, which had caught me, and the insides of her mouth were moving mechanically.
She’s simply become a doll who moves her body for pleasure.

It guess it’s fine to not hold back my e.j.a.c.u.l.a.t.i.o.n soon.
Thanks to Sunou’s all-out movements, my lower half became hot even quicker than usual.

“Nnbbgh!!”

I strongly chewed and restrained Sunou’s wild tongue, licking it all over with my own.
With a force that would completely break the insides of her v.a.g.i.n.a, I shoved my p.e.n.i.s deep inside of her.
While feeling that the blood throughout my body gathered into my crotch, I e.j.a.c.u.l.a.t.ed as though it exploded.

“Ngh, nnbbuuuuuuuuuuuuuuuggghhh!! Puh…………agghh!!”

With a throb, the s.e.m.e.n that didn’t fit inside of Sunou’s v.a.g.i.n.a spilled out.
After I released her mouth, Sunou jerked her head backwards before fainting.

“I guess it’s done.”
“No, not yet, Master.”

Upon removing my hands from Sunou, Kokoro supported her before letting Sunou sleep on the bed.
After that, Kokoro further held the fainted Sunou’s chin firmly, opening her mouth.

“Please allow her to properly clean it. I’ll hold her down so that her teeth doesn’t touch.”
“……I guess that’s true.”

Because of her implanted suggestions, Sunou won’t suddenly bite me, but there’s still a chance since she’s out cold.
Borrowing Kokoro’s support, I crammed my p.e.n.i.s into Sunou’s mouth.

“Bbuggh……*lick*.”

Rather than biting, the unconscious Sunou went so far as to perform the act of licking my p.e.n.i.s.
After violating the insides of Sunou’s mouth so as to squeeze out the remains, I wiped the sides of my p.e.n.i.s against her face.

“There is still some left over, isn’t there? As expected, Sunou-chan still has a long way to go.”
“Ah, I’ll also do it!”

Kokoro and Mai both came together, seemingly competing as they ran their tongues all over the p.e.n.i.s which Sunou couldn’t clean.
Kokoro aside, Mai also seems to be seeking my p.e.n.i.s inside of her subconscious. She might not mind it even if we were to do more stimulating things after this.

“Nngh~ Somehow, it’s really delis.h.!.+”
“Come now, Mai-san. We need to lick it properly.”
“I’m licking it! Besides, Kokoro-san, this is my territory!”

While pus.h.i.+ng and shoving, the two pressed their tongues against my p.e.n.i.s.
Because of this, I gradually became erect again as the withered p.e.n.i.s towered over them.

“Uh oh.”
“Fufuh, it would seem that there is a follow-up lesson……”

Whilst giving off a feverish look, the duo delightfully stroked my p.e.n.i.s. Even after having done it that much, there still hadn’t had enough, huh.

“But since this will also burden Master, this might be the last one.”
“Yup, yup. As expected, this is for study purposes after all. That’s why I’ll-”
“No, I, who can properly perform the correct method, will go.”
“Eeh~”
“……nngh, de……mon.”

Whilst looking at the clock on the wall, I scratched my head.
Well, I still have the strength, and there’s still time. In that case, I guess it’s fine if I accompany them up until the end.

“The both of you know what needs to be said if we’re going to do it, right? For study purposes, I’ll f.u.c.k whoever makes me want to do it more.”
“Yes! I’ll do it as long as it’s Master!”
“I also won’t lose!”

Even with that much burden, I endured it. Besides, it might be fine for these two to do their best until they’ve reached the utmost limits of pleasure.
My heart danced in the face of the experiment–correction, lesson that would happen from now as a distorted smile once again emerged from my mouth.
