Why the Heck was I Reincarnated in DxD without a Cheat Power!? (High School DxD SI Chapter 1)

The high school girl was picture of elegance and grace. The daughter of the Hyoudou Household was seen by many as example to what students should aspire to be.

Guys in Kuoh Academy wanted to approach her, but her mature cool aura made them scared to do so, lest they act foolish in her presence. Girls gathered around her, vying for her attention.

As usual she was walking her path home that took her through the shopping district, seemingly not looking for anything in particular.

Something odd gained her attention. It was a girl approaching her with a flyer. A girl...dressed in the cosplay of a devil? It was a very odd scene, and any who knew the Hyoudou scion would assume she would just politely refuse the sales girl in the gimmick outfit.

However rather than taking a flyer...

"Excuse me... Can I actually have two please?"

Bang!

The door of Issei Hyoudou's room was slammed open with a kick.

"Issei, pause the porn and stop beating your meat, I got something awesome to show you!" Atsuko Hyoudou shouted with a wide grin.

"Dammit, Atsuko!" Issei, with practiced lighting speed born of constant panic at his sister's surprise visits, he bookmarked the page and changed the tab to math lecture video, all while hiding the screen with his body and putting his pants back but and hiding the equipment of his "leisure" time. "I told you to knock! Mom and Dad told you to knock before entering a room! Why don't you ever knock!?" It almost looked like he wanted to cry.

Atsuko easily realized that she probably caught right before his happy ending, like she had done before multiple times-blue ball may be hell, but she couldn't help feel amused at inflicting it-and easily pushing Issei's distress out of her mind.

"Yes, yes, little brother. I totally will next time. Now ignoring the small details like your dick and needing to cum-"

"It's not small!" Issei was now in tears.

"No, of course not. It's a very good sized, beautifully sculpted smooth thick cock that will have all the girls wild if they see it." Atsuko patted her baby brother's head to sooth his cute small ego.

"Stop that! I don't wanna hear that from my sister." Issei whined and lightly pushed her hand away.

"Heh. How innocent." Atsuko daintily covered her mouth with her fingers.

"Stop." Issei intensely pointed. "And stop calling 'little brother', we were literally born at the same time."

"Half a second older is half a second longer in the world than you." Atsuko said proudly with her arms crossed.

"That saying doesn't even make sense!" Issei snapped and tapped her arm.

"Doesn't matter!" Atsuko pumped her hand in the air. "What does, is this!" Then she took two pieces of papers out of her jacket and thrusted them in Issei's face.

"Huh, what the...?" He took on of the paper and read them. They were pamphlets with a large circle deign in the middle, and some instructions on the top and bottom of the page. "'Make a contract with a devil and we'll grant your wish'?" Issei gave his sister a pitying look. "Atsuko please tell me you didn't pay money for this?"

"Nope! A cute girl in a devil costume was handing them out." Atsuko grinned at the memory. Issei found himself pouting in jealousy at missing on such a view. "Come on, let's try them out."

"It says to 'wish with a strong desire for the magic circle to activate'. I dunno, Atsuko this seems silly-"

Atsuko was in Issei's face, looking down at him with a wide empty menacing look on her face.

"If you don't do this with me, I will blue ball you for a whole month like the worst No Nut November challenge you can imagine." She spoke in a low voice, compared to that of a haunting ghost girl. Her hair falling over her eyes definitely made her look like Sadako.

The image would definitely be frightening if she didn't need to stand on her tippy toes to accomplish such a feat.

"Alrighto! Let do some witchcraft!" But Issei was sufficiently frightened anyways, and agree to Atsuko's demand with false energetic cheer.

"Yay~." Atsuko raised her hands and clapped them in the air.

=====

Rias Gremory was in her office Occult Research Club building, finishing her work for the day when she felt a summoning tug at her.

She checked to see who was pulling on her through the contract flyer, as is usual for safety measures.

"Oh," her eyes slightly widened, before she smiled at this turn of events.

She had been taking her time to approach the Hyoudou boy to see if he was worth recruiting, but it looked like her good fortune smiled at her again. Now she can meet, introduce him to the world of the supernatural, and inspect him at her leisure.

"Rias," her Queen, and club Vice President called out. "I'm getting a summons too. It seem like the contracts in close proximity."

Rias raised an eyebrow. "Wait, you mean..."

"The summons I'm getting is from Hyoudou Atsuko." Akeno nodded.

"My, what a surprise. I wonder how Issei convinced his sister to try using a contract flyer?" After all, imaging the aloof no-nonsense Model Student Atsuko believing in something 'superstitious' as devil summoning, was difficult for most people.

"Well, you never truly know how people are like behind closed doors, fu fu fu." Akeno gave a small laugh.

However Rias did see her fair share of people who held differ personas in their work and private lives. Of course, she didn't expect the girl called Next Generation Great Onee-sama to be that different at home.

"She's probably just a little different, more relaxed at home." Rias remarked.

Then again Akeno is the one who has gotten the summons...maybe she wants help confessing her feeling to a boy she's interested in? Rias thought, then nodded to herself at her conclusion.

"Very well, last one of the day. Let's answer this one together then. It should be fun." Rias said in good cheer, and Akeno smiled and nodded in return.

The two devils went to the center of the room, activated their magic to be pulled by the summoning tether and...

"HOLY CRAP, IT WORKED!"

"BOOYAA! WHO DA WO-MAN!"

Well... Rias looked at the scene of Issei looking flabbergasted on his bed with his sister doing a happy dance of pumping her arms in the air and taking exaggerated steps around the room. I suppose Atsuko really relaxes at home?

"Wait, why are the Two Great Onee-samas here?" Issei said with his jaw dropped. "Wait... Atsuko, did we just kidnap our school's celebrities? Shit, are we going to jail!?" He cried out in panic.

Next to her, Akeno covered her mouth and was doing her best to not ruin her cool image by guffawing in laughter.

"Naaah, Issei," Atsuko sat next to her brother and placed an arm around his neck, showing two devils how close the two actually are. Most people in japan tend to be squeamish on physical affection, even simple touch. "The flyers literally materialized them out of thin air, and it said it summons Devils, so clearly they're the devils we're suppose to meet." Atsuko explained.

"So wait, Rias-senpai and Akeno-senpai were devils all along?" Issei wondered. Rias couldn't help by smile at how adorable, if a bit slow, the boy was. It made her want to dot on him, just to seem him blush.

Also his question was a good point to break the ice, and introduce herself.

"That's right, Issei, Atsuko, I am Rias Gremory, and as you two have guess, I am a De-"

"Of course, she's a Devil!" Atsuko interrupted, making Rias's eyebrow twitch, while Akeno's shoulder's shake a bit, as she continued to contain herself from laughter. Atsuko let of her Issei's shoulder to point with both arms at Rias's...waist. "I mean look at those hips!" Issei did so. "Those are literal child-birthing hips. There is no way a girl our age would have those."

Rias began to blush, and nervously sweat at how Atsuko was the more animated one, unlike what she expected.

Akeno covered her nose and mouth with her hand, and took shuddering deep breaths to let out her laughter, without voicing it. She couldn't stop smiling through.

"Huh, you're right. The hip to bust ratio is also perfect. Honestly, the first time I saw Senpai I thought they walked out of a porn studio." Issei said analytically.

"Oh really?" Rias's eyebrow twitched again. Akeno, now seeing her King's reaction, was biting her lips.

The two Hyoudous were proving to be very entertaining.

"'Just a little different, more relaxed at home', huh." Akeno noted.

"Shut it." Rias said under her breath, which only Akeno could hear, as the siblings still seemed engrossed in their discussion.

"I know, right?" Atsuko continued, uncaring of Rias's increased ire. "Like seriously, those breast? No sag, always taut and smooth, but still perky and soft. Can you honestly tell me that breasts that large and supple are natural on girls my age?"

Issei's eyes widened, as he sat up in full realization. "Those breasts aren't natural. They're supernatural!"

"That's right!" Atsuko nodded.

"They are Devils!" He pointed at the two devils like a detective that uncovered a giant mystery.

"Bravo~." Akeno gave a golf clap.

"Okay!" Rias just had about enough. "I'm a Devil, so is Akeno, you summoned us, let's hear your wishes and discuss the price. No sidetracking!" Rias said with a flare of her demonic aura to make the humans focus on her, and listen, while pointing at Akeno when she said the last part.

Akeno pointed herself in mock shock. "Moi?"

"Silence." Rias said. Akeno did so while feeling a shiver. It was fun, but sadly rare, when Rias acted strict like that. "Now..." Rias took a deep breath, before recentering herself and smiling at the human pair, a bit calmer now. "Miss Atsuko, Mister Issei, how about we start over. Rias Gremory, Devil answering your summons to grant a wish. What are your requests?" She said with a smile.

"I want to see real life boobs!" Issei said immediately. Rias huffed in amusement, she suppose she shouldn't be surprise.

"He's lying!" Atsuko cried out, making the devils look at her in surprise.

"No, I'm not." Issei protested.

"He totally is. I wants to finish jacking off since I cockblocked him earlier and now he's blue balled." Atsuko said bluntly, while smiling and nodding to herself, like she was doing her brother a service.

"You didn't have to tell them that!" Issei shouted.

"Oh dear," Akeno chuckled. "Should we switch and I take care of his wish, Buchou?" Akeno said to Rias in merit.

"Let's just," Rias sighed and cover her face with her hand. "Hear what Atsuko wants first."

Honestly, the image Atsuko had cultivated in her school time, had been damaged erratically.

But maybe that's just how she is, alone around her brother as she feel safe and intimate to act freely. Looking at it from that light, it's a pretty heartwarming thing. And that Atsuko was so blasé about sexual matters is due to living with Issei, so I shouldn't be so surprised. Rias comforted herself with the thought.

Atsuko stood on the bed and pointed at her crotch. "I want a magically retractable giant bitchbreaking futa dick, that makes all the bitches go in heat and ahegao, and all the traps be hypnotized."

And thus once and for all, the image of Atsuko Hyoudou was completely and utterly shattered in Rias's mind.

Thud.

And Akeno had fallen on the ground, holding her stomach and guffawing without control.

"What?"

And on that day Rias Gremory first learned that between the Hyoudou siblings, the Oppai Loving Pervert Issei was the tame one.

AN: I know I said I would be working on other stuff, but a spanking scene in Princess of Desolation was draining my motivation. So I wrote this instead.
