Saimin Regulation

Chapter 35: Minami Mai Swimming Training-Arc

The next morning, we decided to swim in the ocean after having the prepared breakfast.

Its likely that this was a standard attraction at this island. Lots of parasols and chairs were prepared since the start, and we were able to swim in swimsuits.

Yahhoi! The waters so clear!!

Mai was cheerful as she was the one who was the most excited. Her swimsuit was an amazingly adorable pink bikini.

*Splatter* her feet in the shallows, she raised up a splash.

its hot. The scorching hellfire burns my skin. The oil-based armour will-!

Youre really black, huh.

As expected, Sunous swimsuit was confirmed to be of gothic style. It had a frilly design that was quite cute, a swimsuit that looked like underwear.

Wearing sunglasses, she held a scoop and bucket in her hands.

Are you going to make a castle?

Kuh!? How did you know!? ah-

A hat with a large brim was placed on top of Sunous head.

Concerned about the strong sunshine, Kokoro had put on the hat that she brought. Sunscreen cant protect ones hair, after all.

Im glad that I brought along two.

Saying this, Kokoro held down the hat that she was wearing so that it wouldnt be blown away by the wind.

Her swimsuit was a string bikini, but completely different from Sunou over here, hers was completely white. The unblemished fabric that was somehow supporting her large breasts incites my impulse to tear it away right here and now.

this is good.

Whats wrong, Rein?

Somehow, this is really nice. Im also glad that I came.

I see.

Reins swimsuit was a two-piece type bikini. Her body expressed her intention that she came here to swim.

Above all, the motionless dolphin-type floating tube that she held at her side displayed the fact that Rein, herself, loved to swim.

The instant I thought this, Rein ran off towards the open sea.

Because her black hair was bundled behind her, she looked like a dog that was waving its tail as it headed towards the sea.

I think shell be fine, but is she just gonna run off by herself?

I will look after her. Sunou-chan, shall we swim before making a castle?

Eh!?

I will make it together with you later. Now then, lets do our warm-up exercises.

If Kokoro-nee-san says so, then

Kokoro smiled at me. Shes probably asking to do it together.

Although I started my warm-up exercises next to Kokoro, whenever her upper body turned backwards, my eyes caught Kokoros large breasts, which had become like soft mountains.

Is something the matter?

no.

This woman is enticing me. Each and every one of her warm-up exercises, when in a swimsuit, were quite erotic.

This is the beauty of the female body.

Kokoro was smiling. While sending me an upwards gaze, she was trying to discern whether or not I was becoming erect.

Thats why I absolutely wont do it.

With my high pride, I refused to change my mind so as to tell her not to get cocky.

Ill do it later.

I see. You will join us later on, correct?

Although Kokoro was disappointed, she trusted in the fact that she could do it for me later. She made an expression of victory. How frustrating.

Then, well be heading off. How about Master?

Ill wait for a little bit.

*Bleegh*!!

After Sunou pulled down her eyelid and stuck out her tongue at me, the two of them chased after Rein together.

I also like to swim, but, for the time being, its necessary for my body to calm down.

I placed my waist down on the long chair in the shade of the parasol.

ah?

Hm?

Beside me, I noticed that Mai was there.

Come to think of it, even though she was the one most hyped up, isnt she gonna go into the ocean?

Dearie me, is Book also not going to swim?

Ill swim later. Rather than swimming, Mai, arent you gonna play?

How rare.

Mai is the type that takes the initiative and joins her friends during times like these. She wouldnt do something so boorish as to not swim just by herself.

In other words, there is a reason for this behaviour.

Can you not swim?

Yeaeeehh!? Howd you find out?!

Ah, no, it was just a hunch, though.

Mai narrowed her eyes and approached me with doubting eyes.

When she leaned forward, I could clearly see her cleavage thanks to her bikini.

The weakness of wearing a swimsuit is that I cant hide my erection. I changed the way my body was facing so that I could hide it as much as possible.

Though, even after doing this, Ill probably be immediately found outah.

Mai, since were here, why not try learning to swim?

Eh, why?

Nah, its just that being able to swim is better, right?

No way. Im more concerned about how Book could tell that I cant swim.

It seems that having me see through the fact that Mai couldnt swim was a humiliation for her.

Since its fundamental to not show your weakness to others and just play it off in the first place, shes probably quite agitated.

As for here, thanks to Kokoros records, I have grasped the menstrual cycle of all four members. I knew that such a hard-to-say reason couldnt possibly be why she wasnt swimming.

And this ended up backfiring on her.

How should I say this, it feels like I just immediately arrived at that answer

Youre not gonna practice, right? Then thats fine.

say, Book. Book, are you able teach people how to swim?

Mais topic abruptly changed into a completely different direction.

As I found it curious, lets continue the conversation.

As long as one can swim, then I think they can teach the general method.

Is that sothen, Book. You teach me!

Me?

Yup. As punishment for figuring me out!

Mais eyes were fixated on me. Her gaze seemed like it was probing someone.

Even though I also felt some kind of danger, I was charmed by Mais expression which she had rarely shown to others.

This was Mais true expression which she occasionally displayed.

I got it.

Alright, lets do it!

Yeah, but lets change the place. There, around that rocky area.

The waves around here werent that strong, so it should be just perfect for practice.

And those rocks guaranteed that the trio wouldnt be able to see us.

You really get it, dont ya!?

Even if friends were here, Mai wouldnt want other people to see this.

I dont know what kind of position I had in her head, but, as expected, I was mistaken.

Wait a second, Ill go get a floating tube.

Kay, kay!

Bringing a floating ring, I headed towards the shadow of the rocks with Mai.

After confirming that we had gone out of the trios field of view-

Then, lets do it!

Yeah, [Over There is Fun].

I announced Mais hypnotic key word.

As though she was suddenly switched off, Mai closed her mouth, standing in a state where her empty eyes did not know what where she was looking at.

After a while, she also lost strength, her arms dangling loosely as her body staggered unsteadily.

Mai, can you hear me?

YesI canhear you.

From here on, you are going to practice swimming with me. I will decide on the method of this practice, but no matter what that entails, please obey what I say.

No matter what it isI will obey.

Even if that were to be something very embarrassing or horrid, it is something that cant be helped in order to become able to swim. Please bear with it.

Yesin order to swimit cant be helped.

This much should do it for now. After this, itll be fine as long as I catch her when necessary.

Since we were above the ocean, I was worried about whether or not the staggering Mai would fall. I guess Ill have her wake up early.

Now then, when I count to 10, you will wake up.

Mais skin was painted with sunscreen, protected so that whatever fell upon her would be repelled.

Without notice, I brushed against and rubbed this skin. A sense of conquest, that was akin to that of desecrating the secret formula that was protecting her, spread inside of my hands.

10!

Removing my hands, I released Mais hypnosis.

Mais pupils gradually regained their glow, returning back to her condition just before being hypnotised as though she were being rewound.

Say, then, whadda we do?

Lets see. First, could you try floating on top of these shallows?

Kay, kay!

Lying on her back, Mai entrusted her body to the surface of the water. But-

Blublublublub!

Are you actually sinking?

Puhah!! Thiss no good!?

Placing my hand against my chin, I first made a thinking gesture before proposing the following.

So your body cant even float, huh? Then, the countermeasure is easy.

Howzat?

Make your breasts bigger.

Haeh?

When the chest grows larger than a certain size, they become able to float on water. If your body sinks, then you should just train your body so that it can float by itself.

Is that so?

Of course, even if the chest floats, it wont be able to substitute for a life preserver.

Mai frowned, being convinced for the time being.

Thats why, Mai, Ill have you immerse yourself in the water once again while I massage your breasts.

Eh, eh!?

This is so you can become able to swim, right? Come on, get inside the water again.

Pushing her shoulders, I forcibly submerged Mai in the waters surface.

After that, I thrust my hands inside of her bikini, digging my fingers into Mais breasts.

Hyah!?

Hey, bear with it.

Her bikini was probably a perfect fit for her size. Adding their volume, my hands were buried into the surface of her breasts, as though squeezing it.

Just as Ive always done, I slowly stroked as though circling them. Occasionally I extended my fingertips to her sides and pushed them, enjoying the reactions that came from giving her various stimuli.

S-Say, Book. This is really embarrassing, you know?

But this is necessary, right?

Yeah, but it doesnt seem like its having much effect, so-

Then it appears that we need to do a little bit more, huh?

Saying this, I removed my swimsuit and exposed my penis.

Mais eyes became round. After all, it was with just this act alone that I merely exposed myself.

Wha, wha!?

By using the penis, well stimulate your female hormones so that your breasts grow larger. This is a treatment thats performed so that you will become able to swim.

Ah, eh, thats right, isnt it? I get it, but-waah!?

Pushing Mais breasts to the center in order to make a valley, I directly thrust my penis between them.

From Mais bikini and her chests cleavage, my penis ended up in a state akin to that of springing forth.

Like this, I started to piston.

Book, Book! Its hot!!

Thats cause its summer.

Not what I meant!! Hyah!?

Almost as though it were another living being, my penis rampaged inside of her cleavage. Meanwhile, my hands continued to roughly handle her breasts.

With a *splatter*, the annoying, leaping seawater told the intensity of our actions.

Wah, wah, aaaahhh!! Hyahn!!

While unable to resist, Mai remained passive.

Her breasts had gotten used to the fondling. As the horny effect was also present, its likely that her female hormones were properly being secreted.

B-Book!

Mais face flushed a deep red, as it had been a while since weve had sexual intercourse.

Ill release it properly, so you do your best as well.

What is!?

Its the thing that will make you secrete hormones, I guess?

Just like this, I turned to Mais face and ejaculated.

With a *twitch*, every time my penis throbbed, Mais chest shook as though being shocked by electricity. A liquid different from the sea water scattered onto her crimson face.

Hyahaaahh!!

Well, about this much should do it, huh?

Haahhaahit kinda, stinks.

Mai smelled the semen that trickled down her face with a *sniff*, and-

Disgusting.

-seemingly having entered her mouth, she swallowed it.

Despite the fact that this was done for the purposes of swimming, she should know that this is sperm.

Hey, its not time to get tired yet.

Books such a Spartan!

Here, use the floating ring as a substitute for a kickboard. Thats right. Its form practice now.

Kaay!

Next, Mai turned her back towards me, and made her upper body float with the floating ring that she brought.

Lets go to a place slightly deeper like this. That being said, well only be immersed up until our waists. Because of that, Im going to remove your swimsuits bottom.

Um, is Book gonna take it off?

Both of your hands will hold onto the floating ring. From there, Ill lift up your legs and support you.

W-Wai-!?

Mai couldnt swim. After guiding her to the sea at a depth where her waist was soaked, I dived and removed her swimsuits bottom.

Finding it a good thing that she couldnt resist, I raised both of Mais legs, forcing her into a position where her butt surfaced out of the water.

Im scared, yknow!? Put me down

Bear with it. Ill be supporting you so that you wont fall, ok. Come on, face forward.

Support?

Mai desperately clung to the floating ring.

I spread out Mais unprotected feet to the sides, making it so I could clearly view her vagina from behind.

From there, I slowly advanced, and inserted my penis into Mai.

Igh!!? Iehh?!! Ah, eeehh!! Why did you put it in, Book!?!

To support you. So that Mai doesnt fall, Ive become your support. You wont sink like this so keep in mind to maintain this position.

This is my first attempt at having sex with a woman floating on the waters surface. As for the position, it was one that closely resembled that of daki-age.

(TL Note: https://pan-pan.co/detail/73780#15)

No, since Mai, herself, was floating due to the floating ring, I could insert my penis even deeper than the daki-age position.

H-Hey!!

There, properly grab the floating ring since its a replacement for the kickboard. If only your legs float up, youre gonna drown.

Igh, aahh!! S-Somethingswait a-!!?

While in a feverish rush, Mai became desperate due to the suggestions as she grabbed the floating ring. With her face bright red, she continued to protest against me.

As though ridiculing such a Mai, I moved my hips back and forth.

Ah, hyaahh!!

Mai couldnt resist. On the contrary, she was person who couldnt swim, simply floating on the water.

Thinking it a good thing that she couldnt move her body, I felt a sense of fulfilment from the fact that I was one-sidedly violating her.

Here, hold on tight.

Hyahkyaah!! Aaaah!!

I dont know what Mai was thinking, but she exerted lots of strength into both of her legs and tightened her vagina.

To think that, in the face of the phrase grab, the thing she gripped onto was my penis.

From her perspective, she was probably risking her life. That desperation caused her to firmly cling to my penis.

Ah, ah, aahh!!!

Whenever I pulled my waist back, Mais vagina groaned with a *twitch*, pleading with me not to separate as it tried to prevent my escape.

W-Wait, kyahaaaaaaaaahhhh!!!!

Upon piercing deeply, her body arched backwards as she climaxed.

Roused by her body, which seemed as though it would lose all its strength, Mai clung to the floating ring.

That pattern of unstable movements, which were further pushed into disarray by my movements, bestowed a new sensation to my penis simultaneously.

Just a little bit, and itll end soon. Keep it up.

Ah, ah, hey, quickly!! Please make it quick!!

There!!

As though pushing upwards, I planted my penis up until Mais depths. Like this, as though to drown her vagina, I started ejaculating.

Kyaaaaaaaaaaaaaaaaaaaaah!!!!! Aahh!!!!

Mai opened her mouth so much that her tongue stuck out, as she raised a hoarse voice.

By being bathed in semen, the climax from her suggestion probably reached the highest wave.

Ah

Whoa.

Perhaps having her strength exhausted by this, Mais hands slipped from the floating ring as she was about to sink into the water.

I grabbed Mais chest and dragged her up. It was quite a soft and convenient handle.

Oh

Oh?

Can I swim? Im already-

Haha, well you did your best, after all. Lets resume after a little rest.

In the first place, this was swimming practice, huh.

For the time being, since Ive cleared up my lust, I should do my best as such from now on.

From inside the vagina of Mais flaccid body, semen clouded the waters colour, similar to how paint spilled into water.
