Materia R-18.

( Yuuki's POV )

The boy I had rescued was called Hirano Kohta, he was quite shy and after telling me his name he didn't say anything else, from what the bullies said and Kohta's attitude this wasn't the first time something like that happened but I'll deal with it another time right now I'll take him to the infirmary.

Yuuki: Shizuka, are you here?

Entering the infirmary I looked around and I saw Shizuka with her head on her desk taking a nap but she woke up when she heard my voice.

Shizuka: Ueh? Oh, Yuuki you came to see me~

Shizuka got up and ran to hug me, from the moment we met there is a strange attraction between us and she has always behaved extremely familiar with me and after what happened in the pool the girls get mad at me if I don't pay enough attention to her.

Yuuki: I didn't come to see you this time Shizuka.

Shizuka: Mou, don't just pay attention to my little sisters, I'm here too.

Shizuka started pouting and she got rid of the bad taste in my mouth after what happened with the bullies, I patted her head to calm her down.

Yuuki: don't say things like that Shizuka, I promise I'll come to see you more often, but could you help my friend here first?

Shizuka: okay~ please sit down.

Shizuka's mood changed immediately and she had a smile and hummed as she worked, thankfully the only serious injury Kohta had was a sprained wrist.

When Shizuka finished she gave me another hug and Kohta and I left the infirmary and we walked to the roof in silence.

Kohta: w-why did you help me?

Yuuki: I didn't have a reason, I could help you so I did.

He was obviously confused that a plugin had helped him but to me that was normal.

Kohta: Don't take this the wrong way, but I think you're weird.

Yuuki: Thank you.

While we were all eating on the rooftop we talked a bit about ourselves and since we had two girls named Saya I started calling Endou Saya with a nickname, Saya-shi, and Takagi Saya just by name, everyone asked us questions about our life before we moved in and we tried to answer without saying anything too weird.

Saya didn't say anything that we didn't already know from our research on her but you can't expect to know everything about a person in one day, our first day of school was pretty short but at least I managed to get a piece of information that will keep me somewhat busy tomorrow.

When classes finished we were walking towards the school gate, Uzume appeared out of nowhere and jumped into my arms and behind her, I saw Kuno and Chiho, we were drawing attention again but she wasn't finished, she put my head on her breasts and she let out a little erotic moan and I could feel the envy in our spectators, when she let go I whispered in her ear.

Yuuki: what are you planning Uzume?

Uzume: oh, I'm just having some fun.

I told Akitsu and Kaie to go home and tell the others to come to the MBI building when they have time because I had a surprise for all of them and when they left I spent some time walking around the city with Uzume Chiho and Kuno until we ended up at the doors of the MBI building where Ana was in charge of the company, we had already started selling our technology and we had three stores in the city that were doing great and at the time Ana was concentrating on buying a hospital at my request.

Kuno: Yuuki you should clean this place more often.

We went into my lab, which was pretty messy but this is a neat mess for me, I went to my work table where I took three green marbles and gave one to each of the girls and they looked at me confused.

Uzume: what's this?

Yuuki: This is the result of my first big project, Materia.

Chiho: oh and what does it do?

Yuuki: Concentrate, imagine a ball of energy forming in the palm of her hands.

The girls did as I told them and within seconds a ball of fire formed in the palms of their hands.

Yuuki: Materias are wearable Sekirei cores that give the powers of a Sekirei to anyone who holds it.

Uzume: That's cool, but it wouldn't be inconvenient to have to hold them during a fight.

Yuuki: yes, that's why I also created this.

I lowered my left sleeve and I showed them the black bracelet I was wearing and with a movement of my fingers a pyramid of energy formed around me, I had turned barrier BIM technology into a bracelet.

Yuuki: we can put the Materia in these barrier bracelets, the barrier is activated with a mental command or with a movement of the ring finger, I created three different Materia that represent type 1, type 2, and type 3 Sekirei abilities.

Uzume: wow, that means that we can have all the abilities of the others just like you.

I threw a lightning Materia at Uzume but she couldn't activate it this time.

Yuuki: not exactly, you need compatibility and the limit of how many can be used at the same time depends on each person, I can only use five at the same time.

Type 1 Materias that improve the body are yellow, type 2 that control elements are green, and type 3 Materias that give special abilities such as Matsu's technology control are purple, since I already had all the abilities of the others, I had five yellow Materia that allowed me to use a little of my control of time and space to use short distance teleportation and slow time momentarily.

Uzume: I guess this is why you wanted everyone to gather here.

Kuno: Then we have to hurry.

Yuuki: oh I like how that sounds.

///// R-18 /////

We moved to our second house below my lab and the girls immediately changed into uniforms from my school, but these were much more erotic, her short skirt barely covered anything and they were exposing a lot of cleavage, I wasted no time jumping on Uzume who kept turning me on since school ended, I put my hand under her bra and I kissed her deeply and when our lips parted I picked her up and threw her on the bed, Uzume looked at me seductively and she spread her legs, she moved her panties and exposed her wet pussy to me.

Uzume: Come here Yuuki~ I've been waiting for this all day.

I lowered my pants and rammed my hard cock into Uzume without holding back, Her moans of arousal filled the room but she was quickly silenced as Chiho sat on her face and she put her hands around my neck.

While I was fucking Uzume and kissing Chiho, Kuno came over and took off my shirt, she undressed Chiho and finally herself, and then ended the kiss between Chiho and me by putting a finger in Chiho's ass.

I kissed Kuno while I came inside Uzume and when I finished, I pushed Chiho and Kuno onto the bed.

With my cock inside Uzume, Chiho and Kuno were masturbating while waiting to be next.

Yuuki: let me hear your melodious moans, Kuno.

I put two fingers inside Chiho and I start fucking Kuno, making her moan as much as possible, I switched between the three of them coming inside and over them until they were completely covered in my cum, and when they could barely move I picked Chiho up and put her above Kuno, they had their second wind and they moved their hips to the same rhythm as me, while I was fucking them I could feel that my other sekireis had entered the building and I slowed down time outside our room to enjoy ourselves a little more.

When I finished, the three of them had passed out and I kissed them on their foreheads before leaving the room to talk to the others.
