「 Sorry, Mana 」

I whisper after my long ejaculation as I embrace Mana who is exhausted above me.

「 Huh, why? 」

「 That wasn’t a lot 」

I ejaculated too many times today already.

As expected, the volume is lacking now.

「 Geez, you don’t have to mind that 」

Mana kissed me and sips on my tongue.

「 I’m happy that you embrace me like this 」

Mana rubs her nose with mine.

「 Onii-chan, I’ll be staying over tonight 」

This is an old building used for training for Kouzuki SS>

「 I’ll look after the girls 」

Mana looked at Eri and Rie and smiled.

「 Onii-chan, shouldn’t you be going back together with Ruri-oneechan by now? 」

Ruriko came here travelling incognito.

It would be bad if we don’t return to the Kouzuki mansion while it’s still evening.

「 Indeed. Onii-sama, I think that Misuzu-oneesama’s already waiting 」

Ruriko’s right, Misuzu, and the girls are waiting for us to return. We have to give Kaan Momoko-neechan a report through Torii-san too.

「 Right, we need to go back now 」

Still.

Is it okay to leave the twins to just Mana?

「 Should I stay too? 」

Yomi reads my thoughts and asked.

「 No need. Yomi-oneechan and Tsukiko-san haven’t eaten dinner yet, right? Go back and eat dinner 」

Mana smiled and said.

Right, Yomi should be tired now.

She disposed of the Yakuza and monitored the situation of the twins.

She used her Miko power all night. It’s about time she loosens up.

Then...

「 Okay~ Hey~ Coming in~ 」

The door to the nap room opens and Nei comes in.

「 Done fucking? I thought that it would be about time and so I came in at this moment but...Ah! Yo-chan’s still inside Mana-chan! 」

Nei grins as she looks at us.

Either way, she’s watching what’s happening here in the monitoring room.

「 Okay, good job Yo-chan! I’ll stay here by the way. That’s why Mana-chan and I will look after the twins! 」

Nei and Mana will look after the twins?

「 Minaho-oneechan will also stay, Kinoshita-san and other people from Kouzuki SS will also remain. We can’t make a move until morning. There’s no rush anyway 」

Kouzuki SS people also kept their alert status in high ever since the party.

Now that Tendou Sadao and the Kansai Yakuza teams are gone, they can take it easy now.

Tendou Otome, Tokuda Sonoko-san, Kurosawa-san, Eri, and Rie can stay in here until tomorrow.

「 With that said, Eri-chan, Rie-chan, are you girls hungry? Let’s go eat some food on the next room 」

NEi smiled at the twins.

「 I-I... 」

「 Yes, I... 」

The twins look at each other.

「 Nobody’s going to bully you, don’t worry. You’re both Yo-chan’s sex slaves, right? Then you can eat as much delicious food as you want, but don’t get fat 」

Nei smiled wryly.

「 Both of you need to stay as cute slaves. If you eat too much, you won’t look cute, and I won’t need to tell you what happens next 」

The twins trembled.

「 Nei-oneechan, you’re putting too many threats. It’s okay. You can eat balanced meals and do exercise. Besides, you two can have a program that you can follow and I’ll be with you. You’ll become more beautiful. Just like Mana. Your path to follow is to become healthy and beautiful! You two will be receiving Onii-chan’s love from now on after all 」

Mana smiled.

She gets up.

My penis comes out from Mana’s vagina.

Semen and love nectar spills down from Mana’s insides to my stomach.

「 Eat a lot, sleep a lot, exercise to make your body beautiful, and then once you have a lot of sex with Yo-chan, you’ll be brimming with charm as a woman 」

Mana who just reached climax and received my semen emits a bewitching aura that it’s hard to imagine that she’s a young girl.

「 I become more beautiful the more Onii-chan ejaculates inside me! 」

「 Yes, sex with Onii-sama is filled with kindness and love 」

Mana and Ruriko said.

The twins are making a face questioning whether it’s true or not.

Well, of course, they’ll think like that.

「 It’s true that you become more beautiful when you have sex. But, only when doing it with someone you love 」

Nei says, and she brings in a paper bag from outside the room.

「 Oh, here’s your change of clothes. Although that’s the maid corps uniform from Kouzuki SS 」

Oh right, they can’t stay here wearing just a white school swimsuit.

Besides, I tore off Eri’s swimsuit.

「 The sizes of the underwear don’t match but for now, I got some sports bra and panty, put these on 」

Nei hands over the change of clothes to the twins

「 Uhm, if possible, we’d like to wash our bodies first 」

Eri who just lost her virginity said.

She wants to wash away her sweaty body and the semen in her.

「 You’ll have to wait for a little longer. We’re going to have doctors give the two of you medical examination. We still have woman doctors here 」

Nei said.

「 Look, Yo-chan’s going to enjoy your bodies from now on, and so it’s better to check how much damage you took after losing virginity before taking a shower 」

She smiled and speaks like it’s natural.

「 That’s right. Mana also took a medical exam from a doctor after Onii-chan raped me for the first time 」

「 Ruriko too. I had a doctor look at me. It gives you peace of mind 」

Mana and Ruriko speak like it’s natural.

「 Does that mean, uhm, earlier, Onii-san came inside me but is that uhm, are they going to take measures so I don’t get pregnant? 」

Eri asks bashfully.

She seems to be worried that I came inside you.

「 Oh? You girls don’t get it? 」

Nei shows a teasing smile.

「 Eri-chan and Rie-chan, you two are Yo-chan’s slaves. And so, Yo-chan’s the one to decide whether you get pregnant or not. You don’t have to worry about it 」

「 Naturally 」

「 That’s right. Mana’s also ready to bear Onii-chan’s child anytime 」

「 Yes. And if make one, we’ll give birth to it 」

Nei said. Ruriko, Mana, and Yomi, the slave trio affirmed.

「 B-But 」

「 R-Right, Eri-chan 」

The twins are confused.

「 What are you afraid of? If Eri-chan bears Onii-chan’s child, then we will all raise the child. 」 Onii-chan’s child is our child 」

「 That’s right. You don’t have to worry. We’re not pushing the child to you girls. Onii-sama’s child will get along with everyone, and they will be raised in the best environment. 」

「 Yomi too. That’s why you don’t have to be afraid. You know that Tsukiko-oneesama and I can read people’s thoughts and force them to obey us, right? 」

Yomi reminds the twins.

「 T-That’s... 」

「 Well, we do, but... 」

The twins replied. Yomi;

「 Our Master is always serious. He never lies. He’s showing his intent to everything he says. I can guarantee that since I can read his thoughts 」

She smiled.

「 That’s why, when he says that he’ll look after his sex slaves for the rest of his life, he’s serious about it. And when he said that he’ll make you bear his child, he’s also serious. This is why Yomi follows Master 」

「 As long as you girls don’t betray Onii-sama, serve him as sex slaves, then we will keep you safe 」

「 That’s right. Mana and the girls are just like you, Onii-chan’s sex slaves! 」

「 Yomi and everyone will bear Sensei’s child 」

「 Who knows who will get it first but that’s for Onii-sama to decide anyway 」

「 Mana and everyone swears to treasure the child as everyone’s child no matter who gives birth 」

The twins are amazed by the bright voices of their sex slave seniors.

「 I mean, currently, Yo-chan has two children expecting delivery 」

Nei said.

「 That’s right. One is Mana’s real Onee-chan. Onii-chan both raped Mana and Onee-chan for our first times but now we’re living together 」

Mana laughs.

「 The other one is Nagisa-sama 」

Ruriko said.

「 Katsuko-oneechan plans to join in but she’s not yet pregnant 」

Nei laughs.

「 Maybe Mana-chan will get pregnant before Katsuko-oneechan 」

「 Ee~ Maybe Ai-chan comes first? 」

「 Yo, that’s definitely possible 」

Nei and Mana smile at each other.

「 It’s not just the two of you in this world 」

Lastly, Yomi speaks to the twins.

◇ ◇ ◇

「 Well then, leave the rest to us 」

Nei tells me.

Everyone puts on their clothes.

Then, we all move to our destinations.

「 Onii-chan, goodbye. 」 You two, go greet your Master off too 」

Mana urged the twins.

「 Ah, yes, g-goodnight. Onii-san 」

「 Good night, Onii-san. U-Uhm 」

Rie mumbles.

「 What? 」

「 Onii-san, what’s your name? Or is it okay if we call Onii-san as ‘Onii-san?’ 」

Huh?

「 Oh right. Onii-san probably introduced himself earlier but sorry, I don’t remember it

Oh right.

「 THen, I’ll tell you, girls. He’s the successor of the criminal organization named “Black Forest,” and his name is Kuromori Kou-Oniichan 」

Mana answered for me.

「 And I’m Mana 」

「 And I’m Ruriko 」

「 I’m Yomi 」

They speak only of their first names.

We shouldn’t tell the twins that Ruriko is the young lady of Kouzuki house for now.

「 I’m Nei, well, you girls remember that 」

Nei says with a smile.

「 So, how about the way we call you? 」

「 If we’re slaves, then do we call you “Master?” 」

That’s...

「 Sorry, I already have a girl who calls me “Master” 」

「 Right. Michi-oneechan monopolizes that call 」

「 Hmm, if anyone else uses “Master” Mitchan would get angry 」

「 And since it’s Michi, she will be furious 」

「 I think that you shouldn’t 」

Mana, Nei, Ruriko, and Yomi replies.

「 Mana’s using “Onii-chan” 」

「 Ruriko’s using “Onii-sama” already 」

「 I guess there’s no problem using “Onii-san,” right, Yo-chan? 」

Nei looks at me.

「 But, is it okay if the two of them use the same call? 」

I think that they should gain independence to stop this two in one character.

That means having separate ways to call me.

「 Well, there’s no need to hurry. We can talk about it later 」

I said.

「 Okay, Yo-chan. Mana-chan and I will think with the twins 」

「 Yeah, well then, Good night. Ya-chan, Mana, Eri & Rie, see you tomorrow 」

I smiled at the four.

「 Yeah. See you tomorrow Yo-chan, now everyone follow me! First, let’s eat, then go to a doctor, and then take a shower! 」

「 Come, let’s follow Nei-oneechan 」

「 Ah, yes, excuse us, Onii-san 」

「 Good night, Onii-san 」

After greeting us off, the four left the nap room.

「 Haaaaaaaaa 」

I sighed loudly.

「 I’m tired. Really tired 」

The tiredness attacks my body as soon as the twins are gone.

「 Sensei, you did your best not showing a tired face when in front of the twins 」

Yomi who can read my thoughts knows that.

「 Yeah, of course. I can’t show any weakness to Eri and Rie right now. I had to act like a man who doesn’t know fatigue. If I show weakness, those girls will not trust me, right? 」

Not until the twins believe that “We can trust this Onii-san”

「 Onii-sama, you really are a hard worker 」

Ruriko clings to me.

「 Ruriko? 」

「 Everyone is gone for a while, and so just a moment 」

「 Yomi too 」

Yomi also clings to me.

Her soft meat and warm temperature...

「 Oh, I feel like you girls are charging me up 」

「 I’m happy that you say that 」

Ruriko smiled.

「 Anyway, we can leave the twins to Ya-chan and Mana 」

I persuade myself.

「 I think that’s the right choice. They can create an intimate relationship with the two 」

Ruriko said. 1

「 If Tsukiko-oneesama and I are present, the girls will remain wary, and so Nei-oneesama’s thoughts say that we should back off for tonight 」

I see.

There’s the likelihood that Tsukiko and Yomi read their minds and control their bodies.

「 Besides, the two have a bright personality. 」

Ruriko said, but...

Both Mana and Nei forged that personality of theirs.

Nei and Mana act cheerfully to erase their past self as Yasuko and Maika.

「 That’s why it shows effect. The twins have their “Right? Rie-chan,” and “Right. Eri-chan”

Yomi said.

Nei and Mana who are both skilled in acting can dig the hearts of the twins out of the ground.

After all, the two are caring for younger girls.

I think that it’s right to leave Eri and Rie to Nei and Mana for tonight.

「 I think that Onii-sama’s training for them is good enough. What’s left is for them to take time to mature

Ruriko said.

Right. You can’t create bonds of trust with people that fast.

◇ ◇ ◇

Ruriko, Yomi, and I head back to the monitoring room next door.

Edie, Haiji, Tsukiko, and Rei-chan’s waiting.

「 That’s a horrible face, Darling. Exhausted? 」

Edie looks at me and smiled.

「 Well, it’s natural 」

I sit down on the floor.

「 Do you want me to carry you in my arms until we reach the Kouzuki mansion? 」

That’s...

If it’s Edie’s strength, I’m sure that she can, but...

Her height isn’t that different from mine.

It doesn’t look great at all.

「 Edie. That would be my job 」

Rei-chan laughs.

If it’s Rei-chan, who’s tall, I can imagine myself carried in her arms with ease.

「 No, either way, I’ll go back on my own feet. I won’t ask for your help 」

I said.

Why is it that the guy is on the receiving side of the princess carry?

I mean, these two want to carry me.

They’re gallant when in front of others but when it’s just me and them, they become a woman.

「 By the way, Darling 」

Edie calls me

「 What’s this? 」

Edie points at something in front of Haiji-san and her.

This is...

「 A plastic model, right? 」

「 I get that, but what’s the motif of this plastic model? 」

They actually completed making this plastic model.

Original SD No.18 Warrior Seita Lowgrade calm cloud horse-riding special.

「 I think that the motif is from a warrior during the warring states of Japan but this doesn’t look human at all 」

Well, yeah.

The plastic model Edie completed is a centaur.

It’s a human top half and a horse body below.

That doesn’t exist.

Furthermore, this is an image of a Sengoku warrior from the SD Gundam.

「 I don’t get what’s the meaning of the design 」

「 I don’t get it either 」

Haiji-san also added.

The American and half-foreign girl who came to Japan just recently don’t know.

They probably don’t know about Gundam either.

Furthermore, it’s the four body proportions that are deformed, added with warring states image, and also a centaur.

「 We asked Nei but she doesn’t tell us anything and just smiled 」

Nei...

「 I came from a girls’ school, and so I don’t know much about toys for boys 」

Rei-chan said.

「 I get Gunadm but why is it in Warring states? 」

That’s...

I don’t get it either.

「 Tsukiko-oneesama, you read Nei-oneesama’s thoughts, haven’t you? 」

Yomi asks Tsukiko.

「 Nei-oneesama surely knows the right answer 」

Tsukiko...

「 Indeed, I saw Nei-san’s thoughts but I didn’t understand it. It’s something I don’t understand 」

Huh?

「 Like, “He’s the sun of a low-grade warrior and crossed Abram to the sea.” Or “Riding his favorite hours, Oration and combining, reaching 30x speed, or inheriting the second generation obstinate commander”2

Yeah, you won’t understand if you hear the plot this suddenly.

I mean, Nei knows a lot.

Yeah, it’s distorted robots fighting on a warring state world without humans, just robots.

Thinking about it slowly, it’s hard to understand.

A robot riding a horse is already weird but combining with a horse and turning to a centaur and getting 30x faster is even weirder.

「 Is this some mangaka idea or something? And the image inside Nei-san is something I don’t even understand 」

At that moment, I realized that Miko power has a weakness.

Tsukiko and Yomi can read minds but they do not know how to understand it.

historical

They have no way of understanding.

The image doesn’t fit inside Tsukiko’s head.

Then that means.

If it’s with the power to make people obey...

「 Tsukiko, does that mean that you can’t make orders that you can’t create a mental image of? 」

Tsukiko read my thoughts.

「 I see 」

She’s also surprised.

「 I don’t have a driver’s license and so I can’t drive a car myself. However, I know what it means to drive a car, and so I can give orders to drive, however, 」

Tsukiko said.

「 If I do not know the details of the mental image, it will be hard to give orders 」
