Saimin Regulation

I imprinted the swimming form into Mai via hypnosis.

From the outset, Mai, who had good motor skills, being unable to swim was a psychological problem. That’s why it’s best to clear away her nerves and directly insert swimming movements as is.

“Wah, wah, waah~”

Pulling Mai’s hand, I back stepped in time with her flutter kicks.
She should be pretty much able to swim, even without my support. I have a considerable amount of confidence in my own hypnosis.

“There, just a bit more. Next you’ll do it by yourself.”
“Eh, you serious?!”
“I’m serious.”

When I suddenly removed my hand, Mai flamboyantly sank with a splash.

“Oi, oi, wait!”
“Blub bulub–pah!! Book, why!?”
“No, you can already swim now, right?”
“I just drowned!”

Funny. She should definitely be able to do it.
I ran simulations countless times in my head. How could this be the case, there should be absolutely no possibility for it to have failed.
She was able to swim even in that unstable trance. When compared to Kokoro’s martial arts practice, the difficulty was akin to child’s play.
If she properly focuses on swimming, then this girl should be able to swim pretty much automatically.

“You know, Book, you seriously did your best. Although it’s only a little bit, I’ve sorta become able to swim now. Keep it up, keep it up!”
“No, you’re the one who has to keep it up!”

Mai encouraged me with a carefree smile. Certainly, she has become able to swim, even if only slightly.
Why is it only a little bit? Her growth speed is like normal practice–no, it’s actually slower. The suggestions shouldn’t have failed. What’s the problem?

“You should be able to swim!”
“Book, what’s wrong?”
“Ah……no, let’s be calm. That’s right, Mai, imagine it. The figure of you swimming.”
“Okay, hmm.”

Mai closed her eyes, raising her chin slightly as she started thinking. Somehow, it feels a little like she’s waiting for a kiss. The water that was also trickling down was s.e.xy.

“Okay!”
“……then, try swimming by yourself.”

Since Mai abruptly opened her eyes wide, our eyes ended up meeting. How stupid.
In the next instant after I turned away, the grand sound of water sounded with a *splash*.
Following this, I saw Mai’s struggling figure, splas.h.i.+ng about as she was unable to swim well.

“……why? Just, why?”
“Hey, Book.”

Mai stopped swimming before I noticed, and brought her face close to me.
This girl, even though she was like that, she got back up quite quickly. I wonder if that’s because of her personality?
Wary of this girl’s mystery, I slightly took my distance.

“……huh? Well, whatev. Let’s break for a moment.”
“A break……yeah. Let’s take a break.”

There’s no guarantee that I’ll find the cause just by thinking. There’s also the need to calm down a little bit.
Seeing through this dismay of mine, Mai laughed with a grin.

“Then, let’s do it again after the break.”
“Yeah, we’ll definitely keep it up until you can swim.”
“Aww yeah!”

The two of us returned back to the beach where we once were.
In doing so, we happened to meet the trio who had just finished taking a dip in the ocean and were having their break.

“Geh, Demon! You showed yourself from the depths of the obscured ocean, didn’t you!?”
“You were just there a moment ago.”
“Thank you for the hard work! Where did you go, Master!?”

Kokoro’s expression brightened as she immediately rushed to me. She’s so adorable, like a dog that’s become attached to me.

“Kokoron, welcome back!”
“W-Welcome back.”
“Kokoro-nee-san, don’t get close to him! An extraordinary miasma can be felt coming from that demon!”

Sunou’s tension has become slightly strange, huh. She probably swam a lot.
Since the trio had become noisy, I approached the remaining person, Rein.

“Did you have fun?”
“Not yet. I’m just taking a break.”

Perhaps because she was fascinated by the see, Rein continued to gaze in the direction of the open seas for a long time.

“Do you really like the sea that much?”
“It’s scary, but I like it. My grandpa often talks about his war stories. There was a story where he swam to the coast with his best friend when his s.h.i.+p sank.”
“What’s with that?”

The grandpa that Rein spoke of was probably her maternal grandfather. If memory serves, I once heard that he was a powerful guy who was hunting in Hokkaido even now.
Perhaps, it might be that it was this person who had become this girl’s base.

“On the way, they came across sharks and were prepared for death. Even so, their will to live was superior and they drove back the sharks.”
“R-Rein!? That grandpa is a Viking!!”

Sunou became hung up at a strange place. Her eyes were s.h.i.+ning.
I wonder if this story is true? I mean, it’s a shark. He brought his friend to swim in the sea, you know.

“Yes, grandpa apparently struck the tip of the shark’s nose with his fist. A shark’s weak point is the tip of its nose. You’ll do well to remember it.”
“That knowledge isn’t helpful.”

Brawling in the water is fundamentally impossible. The story’s starting to smell even more.
I called out to the hotelman who was standing by in the distance, and asked for drinks. They’ll probably come in about 5 minutes.

“Master.”

It was at that time. Timing it when I was separated from everyone else, she called out to me.

“It’s about the earlier question, but-”
“Yeah, I was teaching Mai how to swim.”

It should be fine to talk to her about this. I also have something I want to consult her about.

“I taught her with hypnosis, but it isn’t going well, and I can’t think of the reason why.”
“Did it fail?”
“Yeah, that’s right, even though the suggestions have been completely instilled into her. For some reason, it’s not going well. If I can’t find the cause for this failure, then I won’t be able to settle down. I was thinking of consulting you about Mai’s situation for a while.”

To my words, Kokoro placed her hand against her chin and pondered.
Making a more severe face than usual, Kokoro gazed at Mai’s expression, who was talking further away. It really helps that she’s seriously thinking about this.
After all, this is a big problem when thinking about the future.

“Due to the suggestions, if Mai-san thinks that she wants to swim, then she will be able to swim, correct?”
“Yeah, that’s right.”
“……I believe I had understood it.”
“What did you say?”

Seemingly convinced of something, Kokoro faced me with a dignified face.
Following this, for some reason, she inappropriately laughed.

“Master, as I do not have any conclusive proof, I believe that we should put it into practice for the time being so that we can see whether or not my thinking is correct.”
“Can you tell by verifying it?”
“Yes, although I will have to leave the means up to Master……”

Kokoro stared fixatedly at Mai with that sharp glint in her eyes. As though trapping her prey, this gaze brought about a dangerous amorousness.

Even after their break, Sunou and Rein began to make a castle on the sandy beach.
Rein might want to swim, but since she was pestered by Sunou, she ended up helping her out. All in all, she really is a person who’s good at looking after others.

Kokoro, Mai, and I–the three of us acted separately. Just in case, we publicly said that we were doing this in order to teach Mai to swim.

“Now then, let’s start!”

After seeing me, Mai entered the ocean first by herself.

“I shall also cooperate.”
“I kinda feel bad getting Kokoron dragged into this, you know–”
“It’s alright. [Please don’t mind it].”
“……yes, I won’t.”

Kokoro promptly used the suggestions that had been placed for this lodging trip. It was an adjustment that would somehow convince the subject when things turn unfavourable, which she used effectively.

“Master, is something the matter?”
“Ah, nothing.”

While holding aloft the parasol I brought along, I sat on the beach chair, having yet to enter the sea as I returned a smirk.

“I was thinking that a Nudist Beach is also not bad.”

Currently, Kokoro and Mai were stark naked.
They were soaked in the crystal clear water up until their waist, but the duo were unable to hide their pubic mounds.
Although I had seen them naked all the time, this clear water surface, and the rays of the sun. Keeping the healthy image while having them naked as well is very arousing.

“Swimming really feels pleasant, doesn’t it? With this appearance, the entire body is. .h.i.t by the water.”

Kokoro lied on her back, and began to swim a backstroke. The two large b.r.e.a.s.t.s that surfaced atop the water were flowing like floating islands.
Mai frowned, blowing bubbles while crouched underwater.

She’s probably envious about being able to swim, huh.

“……hm? Why are you looking at me?”
“Eh~ Well, you know-”
“Master, before that, isn’t there something that you must do?”

Kokoro happily stared at me.
Perhaps because her feelings had switched, Mai finally came to a realisation at that.

“Ah……that’s true, right?”

Kokoro and Mai both directed their lines of sight towards my lower body.

“You can’t swim in the sea with that erection, right?”
“Hm? Yeah, you’re right.”
“Sa~y, Book, you’re too sloppy!”

Currently, I had removed my swimsuit and was exposing my p.e.n.i.s.
The duo became spellbound by my p.e.n.i.s, which had become erect by looking at the two’s healthy figures.

“It’s these sorts of things where Nudists are no good!”
“Is that so? I had no idea.”
“Even though you’d get it if you thought about it.”

Mai rose from the sea and drew closer, showing her chest in front of my p.e.n.i.s.
Placing my waist on the chair that I brought, my p.e.n.i.s soared, as though showing itself off.

“It can’t be helped since the cause was me, but it’s not good to look so much.”
“That’s right. Since Mai is the cause, it won’t do unless you get rid of this erection, right?”

The hypnosis has definitely reached her. It doesn’t seem as though the suggestions haven’t taken effect.
It appears that Mai is having difficulties understanding how to handle an erect p.e.n.i.s. She’s just stroking my p.e.n.i.s with her fingers, almost as though she were touching something swollen.
It was there that Kokoro strongly pushed her aside, bringing her face close to my p.e.n.i.s.

“It won’t settle down with just that. If you do not properly relieve it, then-”
“K-Kokoron, wai-”
“I am also the cause, so I may also offer my support as well, yes?”
“Yeah, I’ll leave it to the both of you.”
“Then, with post haste-”

Kokoro raised her own chest with familiar hand movements, sandwiching my p.e.n.i.s.
Alternatingly rubbing both chests, she gave me a b.o.o.b job.

“S-Say, I’ll do it too!”

Mai also cut in from the side, trying to press her chest against my p.e.n.i.s.
I thought that Kokoro would obstruct her, but apparently the two chose to get along and do it together.

“Now then, let’s wrap it tightly. Since this is for the sake of relieving it. Please make sure to press your nipples and rub it.”
“O-Okay.”

Under Kokoro’s guidance, the fast learning Mai’s movements also improved.
The four b.r.e.a.s.t.s and four nipples began to fiddle with my p.e.n.i.s. While bestowing me with the feeling of their soft skin in its entirety, the soft protuberances occasionally granted me a new stimulus. It felt as though they were using a brush to write words on my p.e.n.i.s.

“Here, Mai-san. You won’t be able to cover the tip, so you have to lick it with your tongue.”
“T-That’s right, isn’t it?”

The two stuck out their tongues, and began to lick the tip of the protruding p.e.n.i.s. From the duo’s perspective, it seemed as though they were giving my p.e.n.i.s a deep kiss.
Kokoro lovingly, and slowly licked it.
With her consciousness hazy, Mai moved her tongue as though she were licking candy.

The two’s chest and faces were covering me, to the extent that I couldn’t see my p.e.n.i.s anymore.
However, the sensations were properly being transmitted.

“Kyah!”
“Ahmu……”

I felt the ferocity of life from my p.e.n.i.s, and, before I knew it, I seemed to have e.j.a.c.u.l.a.t.ed onto the two.
Surprised, Mai closed her eyes.
Kokoro received the s.e.m.e.n with her mouth so as to not let even a single drop escape.

“Ah, it’s going wild-!”

Inside of the two’s chests, my p.e.n.i.s mercilessly trembled.
As a result, the duo’s bodies became covered in s.e.m.e.n.
Kokoro and Mai’s bodies were covered in my sperm. Of course, that wasn’t the end.

“It’s hot……s-somehow-”
“I as well. Perhaps-”
“Women don’t get erect, right?”

The duo’s cheeks blushed, fidgeting as they began to rub their groins. They were clearly in heat.
This was probably promoted because of this resort, but Kokoro appealed to me with eyes more moist than usual.
Mai was still unable to understand what was happening to her, desperately closed her legs in an attempt to hide her itchy crotch.

“But, well, it’s the same sort of thing, huh. Since I’m the cause, I’ll have to relieve it.”
“Yes, Master!!”

Kokoro immediately leaned over me, and tried to insert my p.e.n.i.s inside of her. Her actions were tremendously agile.

“Wait, if the both of you have become like that, then you have to properly take turns.”
“No, that is unnecessary. After all, Mai-san is going to go swim now so she mustn’t exhaust her stamina.”
“That’s quite the logic, huh.”

Without listening to my static, Kokoro wrapped her arms behind my back.
While in a cowgirl position like this, Kokoro inserted my member inside of her v.a.g.i.n.a, as though she were devouring my towering p.e.n.i.s.

“!! ……Master, thank you very much.”
“Wait! Am I really not getting it?! Hey! Boo, boo!”

Mai expressed her discontent, as her brows turned into a ハ shape. I didn’t like this girl’s sullen look as it felt like it was a scheme.
Or rather, when removing Mai’s reservations towards s.e.x via hypnosis, she really becomes aggressive, huh?

“……well, I gotcha. But you know, since I can swim now, do me next, kay?”

After Mai said that nonchalantly, she looked up at the sky as though not knowing what do, and-

“……huh?”

I ended up involuntarily raising my voice in response.

“Kyaaah!!”
“Hm, Book, wa.s.sup?”
“No, you said that you can swim now-”
“Yup, you taught me, so it’s all good. Somehow I think I can swim.”
“Hey, wait!”
“M-Master, you’re thrusting up so strongl-aaaaaah!!”

She thinks she can swim?
Wait, that impression shouldn’t be wrong. The suggestion also has that sort of placebo-like aspect to it.
More than that, I wanted to know the reason for the irritation that was stuck somewhere inside of my head.

“You said that you think you can swim? Then why weren’t you able to swim before!?”
“Aah!! Master! It hurts! It really, truly hurts!”
“Weell, that’s because I didn’t try to. My bad!”
“Kyaaaaaaaaaahh!!!”

In my anger, I strongly gripped Kokoro’s chest as though to crush it. Thrusting my hips upwards deep inside of her v.a.g.i.n.a, I pushed my p.e.n.i.s against the entrance of her uterus and e.j.a.c.u.l.a.t.ed.
Kokoro climaxed as her pain and pleasure combined, her entire body losing energy while looking satisfied.

“Come on, come on! Next, next!”

Mai rushed me, pus.h.i.+ng Kokoro out of the way before mounting herself on top of me.
With a jerk, I held Mai’s shoulders and maintained my distance.

“Why? Why did you do such a thing?”
“What thing?”
“You pretended that you couldn’t swim.”
“Eh~ Isn’t it fine? Hey, let’s have fun now!”

Mai looked at my p.e.n.i.s and tried to insert it.
However, I stood up so as to prevent this. Grabbing Mai’s legs, I tried to flip her upside down as I looked at Kokoro.
Perhaps having guessed my intent, Kokoro, who got up, wordlessly helped me.

“Ooh……eh, eh!? ……abugh!!”
“Mai-san, please open your mouth properly okay?”

When I sat back on the beach chair, Mai’s v.a.g.i.n.a was before my eyes, and my p.e.n.i.s was in front of Mai’s eyes. We were in the 69 position.
Kokoro supported me, as I forcibly inserted my p.e.n.i.s inside of Mai’s mouth.

After gazing at Mai’s v.a.g.i.n.a that was before my eyes, I thrust my fingers inside without hesitation.

“Mmbggh, nnguuggh!!”

My p.e.n.i.s can enter it, so it should be able to handle three. After inserting three fingers into her v.a.g.i.n.a, I stirred up her insides with my fingers as though to pry it open.

“Gguh, bbgh!!”
“There now, properly serve Master’s precious member.”

Pretty much using Mai’s head as though it were a tool, Kokoro made her out to be my p.e.n.i.s’ exclusive s.e.x sleeve.
I have also been practicing with my fingers, so I was thoroughly familiar with something like Mai’s body, which was my practice subject.

“Nngh, nnnnnnnnnnnnnghh!!”
“She’s squirting, huh?”
“Would it be permissible for me to also ask for some after this?”
“Next time.”
“Is that so, how regretful.”
“Aah, aah, nnbgh!!”

Mai’s v.a.g.i.n.a became sopping wet, as my face was covered with her love juice.
It’s likely that, perhaps, she did not understand what I was doing to her, and was just desperately fellating me.

It seems that she had yet to comprehend the fact that her body, which was suddenly reversed, was immersed in pleasure as her mouth and v.a.g.i.n.a were being held down.
That’s fine. To appease this anger, even thought it’s forceful and dark, it’s just perfect.
Before I became accustomed to this situation, my body trembled in order to e.j.a.c.u.l.a.t.e.
And then, as though grinding down rice into a pulp, I placed strength into my fingers that were inside of her v.a.g.i.n.a.

“Hey, I’m c.u.mming.”
“Nbbgggggggggggggggggggggghhh!!”

Mai squirted at the same time as my e.j.a.c.u.l.a.t.i.o.n. Since s.e.m.e.n has entered the inside of her body, it’s likely that her pleasure was increased further.
Before my eyes, Mai’s v.a.g.i.n.a convulsed, *twitching* open and closed. Although I should have taken care of her, it’s also important to have stimulation sometimes.

“d.a.m.n it, I don’t know why she did it, but it was my fault for not noticing that Mai was loafing around. I feel miserable.”
“Master is fine that way. I will do whatever I can to support you, after all.”
“No, I can’t just rely on you completely, Kokoro.”
“In which case, please take your time to understand it. Although I would like it if you could stay the way you are, if at all possible.”
“For the time being, I’ll be depending on you. However, it’s really pathetic if I don’t grow, right?”
“My apologies. It is just my maiden’s heart.”

Kokoro removed Mai from me, and regretfully gazed at the s.e.m.e.n that spilled from her mouth.
Upon thinking just what in the world was she talking about when she spoke about a maiden’s heart-

“Just because I am a slave, you should not underestimate me.”
“The feeling’s mutual.”

After all, there are recently a lot of scenes where I’ve been relying on Kokoro.
At the very least, let’s take care not to break Kokoro’s joyful smile, which held a certain secret.

TL Note:
I really like these chapters with Kokoro and Mai. Now if only Rein was added…
