High School DxD: The Red Dragon Sex Emperor

My parents seem to have taken a liking to Rias, and my dad even said, "We'll have grandchildren soon." He said joking.

"No, that's too soon!" I replied.

---------As I entered the school gate with Rias---------

"Kyaa!! Rias-sama! You look beautiful today too!!"

Male and female students who adored Rias screamed in delight.

"What!? Wait! The one next to Rias-sama is Issei Hyoudou, one of the perverted trio!? Get away from Rias-sama you fucking pervert!!"

Yes, I'm infamous at school as one of the 'perverted trio.' In a bad way, of course.

One of the female students came charging at me, but Rias then made a move I didn't expect.

"Stop it! He is my dear friend. ...I won't forgive anyone who hurts him." She said looking furious.

"!? I-I'm sorry Rias onee-sama!!"

Sensing the underlying anger in Rias's firm attitude, the girl shrank back.

"Well, it's almost time for class. Issei, I'll send for you after school. Come to the old school building. I have something important to discuss and show you."

With those words, I just watched Rias walk away swaying that big booty of hers from side to side.

"Hey, Issei!! You think you're something just because you came to school with Rias-senpai!!"

There appeared Matsuda and Motohama, who were also labeled as part of the perverted trio with me.

However, I had already climbed the adult stairs with Rias. Their actions now felt childish, moreover beneath my level lol.

"Rias-senpai is kind."

I tried to act cool and provoke them.

"What does that mean!!"

"I won't tell you. Figure it out yourself you perverts. Hehe"

Then I sat down at my place as the class started taking action.

----------------------------------

After school, a male student entered my class.

"Kyaa!! Kiba-kun!!"

It was Yuto Kiba Kuoh's idol male student, a second-year handsome boy from the neighboring class.

"Is Issei Hyoudou here?"

Kiba called for me. Oh! So, the 'messenger' Rias mentioned this morning was Kiba!

I walked over to Kiba and stood next to him.

"Eeek!! Having the pervert Hyoudou stand next to Kiba-kun will spread the perversion!!" says one of the female students.

"But isn't a BL pairing of Hyoudou x Kiba also possible?"

"Which one's the top? Which one's the bottom?"

...The stares and gossip from some of the girls really hurt.

"Oi Kiba! Let's go! Let's get out of here"

Kiba and I then quickly headed towards the old school building.

 ----------------------------------

"We're here, Hyoudou-kun." He said.

"...So this is the Occult Research Club of the old school building."

Although there was a "Do Not Enter" tape in front of the old school building, it looks like this.

"President. I've brought Issei Hyoudou-kun!"

Prompted by Kiba, I entered the clubroom.

Inside was,

"Oh? Are you Issei Hyoudou-kun?"

"H-Himejima Akeno-senpai!"

Standing there was one of the two great elder sisters, alongside Rias, the third-year student Himejima Akeno-senpai.

Her glossy black ponytail was gorgeous, but what really caught my eye was her massive breasts that rivaled Rias's! Rias's breasts are great, but someday I also want to savor Akeno-Senpai's breasts!

"Oh my, are you interested in my breasts?"

Though she was smiling gently, she still seemed to be on guard. Well, given my reputation as a pervert, it's only natural.

As I shifted my gaze, there was another girl at the table. I know this girl too.

"...Toujou Koneko. First-year."

First-year Koneko-chan was popular for her small Loli frame and cuteness, just like a cat, as her name suggests.

"...You can't have it."

Koneko-chan, who was eating pudding, glared at me with a sullen look.

"Huh?"

'Now that I think about it, where's Rias who called me here? Just as I was wondering that,

Shhhhhh

In the corner of the clubroom, there was a shower room. And in there was a silhouette with rich curves! Which means that silhouette is surely...!

"President. Here are your clothes."

"Thank you, Akeno."

Behind the curtain, is Rias completely naked?

Then, Rias finished changing and emerged from behind the curtain.

"I'm sorry, Issei. I called you here and ended up taking a shower. Please forgive me." She said taking a set on the sofa as Akeno brought her a cup of tea.

--------Then let us start--------

"Well then, Issei. ...To put it bluntly, you have already died as a human. Which means you are no longer a human being." Rias said.

"What?"

"The truth is, none of us are human. ...We are all devils." Rias said.

With those words, black wings emerged from the backs of Rias, Akeno-senpai, Kiba, and Koneko-chan!

"And you too have been reincarnated as a devil."

Just as I felt an unfamiliar sensation on my back, black wings, just like everyone else's, sprouted from me!

"No way, so I really had died..."

"Issei, I apologize for turning you into a devil without your consent. Your parents might be in danger too, but I am on your side."

Hearing those words, I made up my mind. Well I made up my mind the moment my eyes met Rias's.

"Rias-senpai. I am grateful to you for saving me from the brink of death. From now on, I will live as a devil for your sake and I am on your side too."

"Thank you, Issei. Now, welcome to the Occult Research Club. From now on, you are also a member of this club and part of my peerage. Everyone, please introduce yourselves properly."

"I am Yuuto Kiba. I'm a second-year student. Nice to meet you, Hyoudou-kun."

"...Koneko Toujou, first-year. Nice to meet you, Hyoudou-san."

"I am Akeno Himejima, a third-year. I am the vice-president of the Occult Research Club."

"Lastly, I am Rias Gremory, a third-year. I am the president of the Occult Research Club. Nice to meet you."

Thus, my first day as a member of the Occult Research Club came to an end.

It seems that the devil society has experienced a drastic population decline, so polygamy is allowed.

This means I can fulfill my dream of having a harem, something I've dreamed of since elementary school.

A journey of a thousand miles begins with a single step.

My first job was dealing with boys and girls around elementary school age, but since they were obedient, I received good reviews.

Then, went and dealt with Morisawa-san, one of Koneko-Chan's clients, and we had an enthusiastic discussion.

"...Good job, Issei."

When I returned to the clubroom, Rias was there alone, doing some paperwork.

When I looked at the clock, it was already past 9 PM.

"Huh? Where is everyone?"

"Everyone finished their work and went home. I'm the only one left."

"I'm sorry for keeping you so late because of me."

"It's fine. I can see from the surveys that you're working hard."

In the comments section of the survey, there were remarks like "I had fun" and "I want to play with Onii-chan again." It's tiring every day, but seeing those makes me want to keep going.

"Come on, Issei. You must be tired. You can use the shower room over there."

"Really? Then I'll take you up on that."

Encouraged by Rias, I took off my uniform and went into the shower room, unaware of Rias's lustful gaze.
