「Haaaaaa」

I fell exhausted on top of Izumi’s body.

I’ve been having sex continuously for a while now, I’m tired.

I bury my face in Izumi’s soft sweating breasts.

Izumi’s flushed skin feels nice on my cheeks.

「Kou-kun, did you let out a lot?」

Marika whispers.

「Yeah, I did」

My dick is still inside Izumi.

Marika’s right, sex with Izumi is great.

It’s not so much about our body compatibility, but rather, Izumi’s body is very much suited for sex.

She gets wet easily, and she’s tight. She’s slender, but she’s huge in the right places.

Above all that.

When I hold Maki, I feel like I had to be delicate in sex, like handling something fragile, but…

When doing it with Izumi, I feel like she can take it in even if I go rougher, I’m sure of it.

She’s definitely going to love sex.

That’s why I ejaculated with all I got.

「Izumi」

I sucked Izumi’s still stiff nipples.

「Aaahn!」

Izumi, who’s sensitive all over, makes a cute moan.

「So cute, Izumi」

Maki kisses Izumi’s cheeks.

「Maki-samaa」

Izumi’s crying.

「Don’t forget. Izumi’s at her cutest when Kou-kun’s having sex with you. And so, show us more of Izumi having sex with Kou-kun, okay?」

「Uuuu, yes」

Izumi looks up at her master and nodded.

「Now, say thanks to Kou-kun. Say “Thank you for taking Izumi’s virginity”」

Marika, Izumi’s other Master, orders her.

「Thank you for…taking Izumi’s virginity」

Izumi looked up at me with teary eyes and said.

「Kou-kun can have his way with you wherever and whenever right?」

「Yes. I understand」

Izumi’s transformation into a pet has been completed.

「I’m pulling out」

I finally got up and pull my penis out of Izumi.

「Uuuu」

As soon as my glans popped out, Izumi’s body wriggled a bit.

A little later and my semen drips down from Izumi’s slit.

White fluid is mixed with virgin blood.

「Okay, stay still」

Ruriko and Michi record Izumi’s post-deflowering image.

「Here, Nii-san」

Luna’s always so thoughtful, offering me a wet towel.

「We’ll do it, it’s our pet’s blood」

Marika said, took the wet towel, and wiped my penis, which was coated with virgin blood, sweat, love nectar, and semen.

「I’ll do it too」

Maki said. I had deflowered Maki and Izumi was continuous.

「Yes, wipe it too, Maki」

「I understand, Marika」

The cold towel feels nice.

「Come here you three, you should take a photo together. This is a good opportunity」

Mariko said.

「Well, let’s take a picture」

Marika nods, and four naked bodies line up on the bed.

「Izumi, don’t hide it. We’re recording it all」

「Yes, Maki-sama」

They’re not hiding their breasts and crotch.

The photos capture their lewd consecutive sex with me.

Then.

「I’m done, now take photos with three of you」

Pets and two owners, leaving the three classmates in a new relationship.

I left the bed.

I feel heavy.

「Yes, Nii-san, sit here. Do you want cold drinks?」

Luna brings a chair to me.

「Thanks, I’ll pass on drinks.」

I sat down on the chair naked.

The photo session continues in bed.

「Maki, let’s have the next one like this」

「Yes, Marika. Izumi, do it like this」

「Yes, Maki-sama」

The three girls I ejaculated with inside the vagina looks like they were having fun.

They have a tremendously close relationship because they have completely lost their mental barriers.

「I think we can join in now, right?」

Mariko told Marika.

「Yes, you can, it can’t be just us」

「Yes, Maki, from now on we’re sisters, so let’s have our pictures taken together」

「Luna-chan, come here too, let’s take photos in turns」

Mariko called Michi too, but…

「Sorry, but it’s about time」

A voice comes from the darkness.

From a space that should be empty.

◇ ◇ ◇

「Don’t be surprised, or should I say that you shouldn’t be surprised」

Luna uses her Miko power, so nobody’s surprised.

They accept it as such.

「It’s already twenty minutes over the schedule」

Minaho-neesan, who was supposed to have gone back to the prostitute cadet’s place in the basement, shows up.

「We can postpone the photo session later」

Kyouko-san, still dressed as Chemin Koda, is also here.

Both of them pretended to leave.

In fact, they were there the whole time, out of sight.

We just didn’t notice them.

No, Luna did that.

I think that Minaho-neesan gave the order beforehand.

「First of all, here」

Minaho-neesan offers Maki a pill and water.

「It’s a drug to prevent pregnancy. Marika and everyone drink it」

Maki, who just lost her virginity and received a creampie, is at risk of pregnancy

「Drink it, Maki, 」

「O-Okay」

Maki receives a pill and cup and drinks it.

Then, she looked at Izumi.

Izumi also looked at Minaho-neesan with a disheartened gaze.

「There’s none for you. Isn’t that obvious? You weren’t expected to have sex with Kou」

She laughs.

「T-That’s…」

Izumi trembles.

「You’re Marika and Maki-san’s pet, right? Then it shouldn’t matter if you get pregnant now. Either way, it’s already decided that you’ll give birth to his child」

「N-No way」

Then.

「Just kidding. How could I not have anticipated that? I prepared one not just for you, Miki-san, Anju-san, and even Kinoshita-san」

Minaho-neesan laughed and shows us a glass container with pills in it.

「But you know, you’re a pet, aren’t you, Igarashi Izumi-san?」

Minaho-neesan…

「Matsumoto Maki-san’s accepted in the family.」 So, she gets the contraceptive without questions, but since you’re a pet, you need to do something before receiving anything, right?」

Minaho-neesan said. Maki reacts faster than Izumi.

「Izumi, bow your head. Then, ask to let you have the contraceptive」

Izumi realized.

Then, she prostrates herself to Minaho-neesan.

Her forehead rubs on the bed sheet.

「Please give me the contraceptive!」

Minaho-neesan…

「Well done, Maki-san, Marika… don’t forget to train your pet. Poorly trained pets are kicked out」

「I’m sorry, Minaho-san」

「I’ll be careful」

Marika and Maki bows their head.

「You need a clear distinction between family and pets, otherwise, girls like Izumi-san get carried away quickly」

I forgot that Igarashi Izumi’s a cute girl, but she’s kind of dumb.

If you don’t watch her all the time, she could go and do something beyond the realm of a pet, causing trouble to the other family members.

「Here’s your pill, once you drink it, you swear that you’ll have sex with Kou, anytime, anywhere, as long as Kou asks for it」

Minaho-neesan hands the pill to Izumi.

「Make the pledge, Izumi, you’re our pet…」

「Make the vow to Minaho-san」

It’s different from her pledge in sex earlier.

Now she’s making the pledge in front of Minaho-neesan and Kyouko-san, the adults.

「I swear」

Izumi replies.

「I’ll have sex with Kou-kun-san wherever, whenever」

「Just Kou」

「Yes, I’ll have sex only with Kou-kun-san」

Oh, Luna’s tying Izumi to the words she’s saying.

「Good, here’s your pill」

Minaho-neesan handed Izumi her pill.

「Izumi, water」

Maki hands the water glass to Izumi.

「T-Thank you, Maki-sama」

Izumi drinks her contraceptive pill.

◇ ◇ ◇

「You can stay at the mansion tonight. I already told your school and dorm about it」

Minaho-neesan tells Marika and the girls

「We’ll send you to school tomorrow morning by car」

「But…」

Maki’s confused.

Marika spends Saturdays and Sundays at the mansion, and she rides a car to school on Monday morning so she doesn’t have a problem with it.

But, Maki came from the school dorm today, with the assumption that Marika’s connection will let them meet someone from the Kouzuki house, and she might get a scholarship.

That’s all her dorm friends know too.

They didn’t expect to stay the night out of the dorm.

No, the news of Maki becoming a scholarship student of Kouzuki house has already reached her school and the dorm.

We can use whatever pretext we want so she could stay out of the dorm.

But, Igarashi Izumi…

Igarashi Izumi, who forcibly followed Maki and Marika, can’t give any reason why she stayed out with Maki.

The students at the school know that Izumi’s skills won’t be enough to make her a scholar like Maki.

「Don’t mind it, she’s your pet, right?」

Minaho-neesan smiled at Maki.

「The school already agreed to change your dorm rooms, so the three of you will be in the same dorm from now on」

The three are in the same room.

「Even your school has a connection to the Kouzuki house and its foundation. Since it’s an opportunity, we got a little unreasonable and they accepted it」

Maki’s a student at their school, and she’s become a scholarship student of the Kouzuki house.

Using that opportunity, there could be students who get selected as scholarship recipients in the future, providing the school with more support

「There will be people who will say bad things about you, and so you should show off your power with all your might」

Although all of the students recognize Maki’s skills in piano…

That also means that there will be people getting jealous and talking behind her back for being a scholar.

If so, then doing something as absurd as changing the dorm rooms as Maki wants, could show that she has influence over the school.

「On the other hand, if you say that you’ll return to your dorms, the teachers will have to wait for you to arrive. They’d want to hear the details of Maki-san’s scholarship, and it’ll turn into an interview that goes past midnight」

Minaho-neesan said.

「If you’re going home tomorrow, the teachers can go home today, and everything will have to be postponed for tomorrow. That’ll make them happy」

If we consider the burden on the teachers, then that’s for the better.

「And so, Izumi-san shouldn’t go home today either」

It would be weird if only Izumi went back to the dorm. She’s been with Maki in the girls for a long time so they also will question her.

「That aside, Izumi-san, do you want to go back to the dorm by yourself?」

Izumi.

「I…with Maki-sama…I want to be with Maki-sama and Marika-sama」

Right…

I mean, it would be bad to send her back home in that state.

Now’s the time to strengthen the relationship between pets and owners.

「About that, Izumi-san」

Kyouko-san suddenly speaks up.

「Could you not call them with “-sama” but “-oneesama” instead?」

Huh?

「Uhm, but Izumi’s at the same age as us」

Maki said.

「That’s what’s great about it, don’t you think? It’s silly. It looks like you’re fooling around when you get called “Onee-sama” by someone of the same age. And other people would just think of it that way」

Kyouko-san said.

「If Maki-san and Izumi-san had a relationship, then it’ll look like two lesbian girls, and some of the students may feel disgusted. Even with Maki-san and Marika-san’s relationship, there will be some disgusted by the relationship, but…」

Kyouko-san said.

「If you add the power word saying “Onee-sama” between the three of you, then they can’t tell if you’re joking, serious, and it’s funny to watch from the outside perspective」

Izumi’s accepted by the students as the cute and silly girl, and if they see her calling someone of the same age “Onee-sama,” then that would be funny to them They’d smile at it.

「Being a comedian is powerful after all」

Maki looks at Izumi.

「Okay… Izumi, from now on call me Maki-oneesama, and Marika as Marika-oneesama」

「Yes, Maki-oneesama, uhm」

Izumi?

「I also like being called Maki-oneesama. Onee-sama…」

She blushed and replied.

「Well then, Maki-san, Marika-san, and Izumi-san could you three take a shower for now?」

Kyouko-san said.

「We just have something important to discuss with him」

She smiled and looked at me.
