High School DxD: The Red Dragon Sex Emperor

In the ten days leading up to the Rating Game against Riser, we, the members of the Occult Research Club, went on a training camp at a villa owned by the Gremory family.

Thanks to Rias, who had already notified the school, there were no issues with our absence. Rias also spoke to my parents, who were happy to send me off.

And so, we are now climbing a small hill towards the villa where we'll be staying. It's been so long since I last walked this much that my knees are already shaking... Not very impressive, considering Rias's fate is on the line.

"We've arrived. This is the villa," said Rias, who was leading the way.

"Wow! Is this really a villa?" Asia exclaimed in surprise.

I was surprised too. It looked more like a mansion from medieval or early modern Europe than a villa!

"Welcome, ladies," said a group of maids who appeared, likely colleagues or subordinates of Grayfia. "Please leave the cleaning, laundry, and meals to us."

These maids were all pure-blood devils, and they were all incredibly beautiful!

"The wealth of a noble family is really something..." Raynare muttered in amazement.

Even though Raynare and the other fallen angels wouldn't be participating in the game, they joined the camp under the guise of club members.

"Everyone! Put your luggage down. After that, we'll have a meeting in the dining hall," Rias instructed, setting the agenda.

For the first five days of the camp, we would focus on individual training to boost our overall strength, and in the last five days, we would practice team coordination for the actual battle.

We changed into our training clothes and began our drills.

[Training 1: Training with Kiba]

"Issei! Your movements are too slow! At this rate, you'll be defeated!" Kiba used his speed to disorient me and counterattack from behind.

Well, I only recently started fighting, so it's not like I'm used to it. But as a man, I can't let my beloved be in danger without stepping in.

"How's this!" My Dragon Shot grazed Kiba, knocking down trees in its path.

"Whew, that was close... But we need to push ourselves this much if we want to defeat Riser and his team." Both Kiba and I lay down, breathing heavily.

My attacks are powerful, but my movements are too slow, leaving me vulnerable to someone as fast as Kiba. On the other hand, Kiba is quick, but his defense is weak, so a strong hit could take him out instantly.

"Alright, break's over. Let's go again, Kiba!"

"Bring it on!"

We continued sparring, determined to overcome our weaknesses.

[Training 2: Training with Koneko]

"Hmph! Hmph! Please hit me! Issei-senpai!" Koneko-chan's punches and kicks were aimed accurately at me as she shouted for me to hit back.

"Counterattack!"

I dodged behind her and landed an elbow to her back. "You're pretty good, Senpai..."

Koneko-chan specializes in close combat, utilizing the power characteristic of the "Rook" piece. She's somewhat similar to me, but she also has speed.

However, she relies a bit too much on her Rook's power, making her attacks somewhat predictable. I thought she should mix in more grappling techniques along with her punches and kicks.

"Asia, heal Koneko-chan."

"Y-Yes! Are you okay, Koneko-chan?" Asia placed her hand over Koneko-chan's back and used her "Twilight Healing" ability to heal her.

"Thank you, Asia-senpai."

As the healer, Asia took care of our injuries. Her personality isn't suited for combat, so she focused solely on support from the back.

"Alright, Senpai. Let's go again!"

"Yeah, I'll take it!" A fierce fight unfolded between me and Koneko-chan.

[Training 3: Training with Akeno]

"Are you sure about this, Issei?"

"Yes, go ahead and hit me with as much lightning as you can." I requested Akeno to go all out during our training.

"Since you've said it, I won't hold back. ...Thunder!"

Akeno prepared a Thunder Break attack, summoning lightning from her right index finger that struck down around us. I tried to avoid getting hit directly, but the lightning seemed to anticipate my movements and struck me several times.

"Gotcha!"

"Ah!" Despite being hit and feeling numb, I managed to grab hold of Akeno.

"Akeno-san, you're excellent with magic, but you're vulnerable when someone gets in close. You're at a disadvantage against close combat types like me or Koneko-chan."

The "Queen" piece combines the abilities of the "Knight," "Rook," and "Bishop." There are three types of Queens, and Akeno-san is a "Bishop"-type Queen.

"Yes, I'm aware of that. If I don't find a way to defend myself, I'll only end up being a burden to everyone."

Just then, Raynare appeared with sports drinks.

"Issei-kun, Akeno-san, I brought you some refreshments."

"Thanks."

"Thank you, Raynare-chan."

"You know, Raynare, why don't you join in this time?" I said.

"Huh?"

"Attack me together with Akeno."

In real battles, it's rare to face an opponent one-on-one; it's usually two-on-one or more. I wanted to get used to fighting against multiple opponents.

"...Alright. Let's do this, Raynare-chan." Said Akeno.

"Okay."

So I began training in a two-on-one scenario, with Raynare teaming up with Akeno against me.

[Training 4: Studying with Rias]

"Alright, Issei, Asia. I'm going to teach you about the 72 Pillars of Solomon."

Training with Rias mainly involved classroom learning, where Asia and I, both newly reincarnated as devils, studied the structure of the devil society.

To be honest, there was so much to memorize that Asia and I were completely overwhelmed.

"Issei, you want to become a 'Harem King' in the future, right? Then you need to learn this."

When Rias put it that way, I had no choice but to give it my all. Asia and I diligently took notes on what we were learning.

[Training 5: Secret Training for a New Technique]

While studying with Rias, I secretly developed a new technique. I wanted to keep it a surprise until the actual battle, so I trained with the fallen angels who weren't participating in the game to perfect it.

When I explained my idea to the three fallen angels, they reacted with:

"Issei-kun, this is too much..."

"Seriously, what do you think women are?"

"This is really creepy, Senpai."

As expected, they gave me half-hearted glares.

"Well, if you don't help me, I won't fuck you anymore." When I threatened to withhold sex, they quickly changed their tune.

"What!? N-No, anything but that!" Raynare said.

"We're already devoted to you, Issei." The big-breasted bluenette added.

"I can't stand that, Senpai!" Mittelt too.

They agreed to help me with the training after all.

When I finished the secret training, I ran into Kiba.

"Issei-kun, what happened to you? You look all beaten up..."

"S-Sorry about that."

The four of us were wearing tattered clothes.

"That's some intense training you're doing."

"Y-Yeah..." I couldn't exactly tell him the truth, so I dodged the question.

At Night-------------

"Everyone, thank you for your hard work. Dinner is ready."

By the time we finished our training, night had fallen. The luxurious meal prepared by the maids was so delicious it made us even hungrier. Koneko-chan even had multiple helpings, and Mittelt, who was sitting next to her, seemed a bit taken aback.

"The open-air bath is ready for you all." Said one of the maids.

'W-What!? An open-air bath!? I have to get in on that!' I thought with a pervy smirk.

"Hehe, Issei, you're drooling." Akeno said.

'Fuck, I need to get it together!'

"I don't mind if we go together, Issei," Rias added.

"Wha—What did you just say!?" I shouted.

"I've been wanting to wash my master's back for a while now." Kalawarner joined in. 

"If Issei-kun says it's okay, then... I wouldn't mind it too." Raynare flushed with her words, I've seen her naked a few times, but Raynare's got a great body too.

"I want to do the thing we did last time..." Kalawarner added, wanting another threesome.

"I want to bathe with Senpai too." Mittelt agreed as well. The only ones left are Asia and Koneko-chan...

"I-I wouldn't mind bathing with Issei-san either... Oh no, I said it!"

Even Asia shyly expressed her desire. And finally, Koneko-chan...

"I... don't want to."

Gah! Koneko-chan really doesn't like me that much!?

"Alright, it's decided. Since even one person refused, sadly, no mixed bathing."

'N-No way...! I wanted to get in that open-air bath so badly!' I almost said it out loud and collapsed onto all fours, utterly defeated.

"Cheer up, Issei-kun. Why don't we go to the large public bath together?"

Kiba tried to comfort me, but there's no way I'm going to enjoy looking at a naked guy! When I have all these beautiful women around me.

Asia Argento's Pov-------------

Light Y*ri Scene----------------

Rias-san led us to the open-air bath. The view was breathtaking, with a sky full of stars twinkling above us.

There were seven of us, and we were all about to enter the open-air bath... but no one was wearing a towel! Everything was out in the open!

"Asia, take off your towel. It's just us girls here."

Rias-san called out to me. I was the only one still wrapped in a towel... I know we're all the same gender, but I'm still embarrassed!

"Gotcha!"

"Kyah!"

Before I knew it, Raynare-san had snuck up behind me and pulled off my towel!

'Oh no, now my breasts and... everything else is exposed...'

"Don't cover up, Asia. Move your hands away." Rias-san urged me.

"Come on, Asia. You have to give in." Akeno also.

"N-Nooo!!" Raynare-san grabbed my wrists, and now my... my private area was completely exposed.

"Hmm, so this is what Asia's pussy looks like. Your hairless crotch is just so cute." Rias-san stared intently at my most private area and made her observations. And everyone else was staring too!

"Alright then, now that Asia's completely bare, let's deepen our bonds, literally starting from scratch!" With the big-breasted princess's declaration, a pink-tinted, all-girls' party began!

"Here, Asia. Why don't you touch my breasts?" Rias-san took my hand and guided it to her own huge boobs.

"How about my boobs? You can rub them if you'd like" she added.

"M-Munyumunyuuun" Rias moaned at the girl's touch.

"They're so big and soft, it's... amazing..." My hands were moving on their own, squeezing Rias Gremory's breasts!

"Hehe, would you like to suck on them?" seductively she added.

"Huh? W-What!?" Caught off guard, I was stunned by Rias-san's bold suggestion!

"It's okay if it's you, Asia. Go ahead, suck on them we are all part of Issei's Harem, so it's okay" Rias-san pulled my head close to her voluptuous tits, guiding my face to her breast.

Before I knew it, I had latched onto her nipple.

Suckle

"Ahhn, How cute, Asia."

Ahhhhh… W-What is this feeling of peace...

I don't have many memories from my childhood, but...

I just want to keep sucking on Rias-san's breasts more and more...

Smooch, smooch, smooch

"My, my, Asia! You're quite the little cuddler, aren't you?" Rias, who was letting me suck her tits like a mom to her daughter, had a smile like that of the Virgin Mary.

Ah, I just want to keep snuggling up like this...

"You've been through so much pain, haven't you? If you want, you can let it all out with me." In a maternal tone, the crimson-haired girl added.

"Ugh..." Her kindness brought tears to my eyes, even devils can be kind.

I cried my heart out in Rias' embrace and felt the same happiness I experienced with Issei-kun.

Raynare's Pov-------------

"What? Akeno-san's father is that man?" Raynare yelled. 

"Yes, that's right." During the training with Akeno-san earlier, I had a sense of déjà vu about that technique.

But Akeno-san's expression was somewhat dark.

"I can't believe you're that man's daughter."

"Yeah, to us, he's someone completely out of reach!"

Kalawarner and Mittelt, who were listening beside me, were also surprised.

"Actually, I'm the daughter of a fallen angel and a human. But after being reincarnated as a devil, I'm neither one nor the other. I'm just a half-breed." Akeno-san said with a self-mocking tone.

"Please don't say that!" Akeno-san mustered the courage to open up, so I have to respond in kind.

"Issei-kun told me… Even if you were born in different worlds, even if you look or speak differently, your wishes can connect you. So, Akeno-san, don't put yourself down. Have confidence in yourself."

"Re... Reynar-chan..." Tears were welling up in Akeno-san's eyes.

"Thank you, Raynare-chan." With those words, Akeno-san and I hugged each other in silence.

Issei's Pov-------------

'I ended up sharing a room with Kiba.'

Ugh, right now the girls are probably all laughing and having fun in the open-air bath...

Aaah so many oppais…

But I don't want to be hated! Besides, there has to be another chance!

I pushed down my desires and fell asleep.
