Reincarnated in the World of High School DxD

Rias loved kissing Kazuki so much, so...

Whether it was a deep, tongue-entwining kiss, a pecking bird-like kiss, or a soft, barely-touching kiss, she adored them all. Whenever they kissed, Rias's face would light up with genuine happiness.

Kazuki loved seeing that expression on her face, and he had lost count of how many times their lips had met since their first kiss.

"Rias..."

"Kazuki... mmm, slurp, chu, slrppsh... mmm, chu..."

Facing each other, they exchanged tender, pecking kisses. All the while, Rias' right hand stroked Kazuki's throbbing cock, her touch firm and deliberate.

Not to be outdone, Kazuki slid his fingers along her slick folds, already drenched and glistening with her arousal. The wet, squelching sounds of her dripping pussy filled the air, mingling with their soft moans.

"Fuuuh!? ...Nnn, chu—nnaah!"

Rias gasped at the sudden stimulation, but her competitive nature kicked in, and she quickened the pace of her hand.

"Nnn!?—chu, slurrpp..."

But Kazuki wasn't about to let her win. He pinched her sensitive clit, eliciting a sharp, muffled cry from her.

"Wahhhhhhhhaaaaa!!"

Her voice was stifled by their locked lips, but her body trembled as a warm wetness spread across Kazuki's hand. She'd already reached a small climax. Encouraged, Kazuki pulled back the hood of her clit, intensifying the stimulation.

"Fu, fuun, mmuu! ...chu, nna, muu..."

The bathroom echoed with a symphony of wet sounds—Rias's moans, the slick slide of her arousal, and the rhythmic strokes of their hands.

Rias' face was flushed with pleasure, her expression drunk on ecstasy. Kazuki, too, was nearing his limit, spurred on by her reactions.

Wanting to bring her to the edge with him, Kazuki slipped a finger inside her, stretching her entrance in preparation for what was to come. The added stimulation pushed Rias closer to her peak, her body trembling as she climbed toward release.

"!!"

"!? Nnnnn~~~~~~~~~~~!!"

Splash! Splash!

Warm spurts of her love juice coated Kazuki's hand, and moments later,

Splurt! Splurt! Splurt!

Thick, white streaks of his cum painted Rias' voluptuous chest and toned stomach. Both of them panted heavily, their lips still pressed together as they slowly pulled apart.

Squishyy… A thin, silver thread connected their mouths before snapping with a soft plop.

"Kazuki..."

"Rias..."

She clung to him with a blissful smile, and he held her gently in return…..

"I'm sorry, Kazuki-kun!! I know... you probably want to go further, right?" Rias spoke softly as she rinsed his back.

"Well, I'd be lying if I said I didn't!! But you've got your position to think about, so it can't be helped."

Not long after they started living together, Grayfia had shown up and laid down a list of conditions.

One of them was a strict ban on sex.

Rias wasn't just any girl, she was the heiress to the prestigious, aristocratic Gremory family. With her status and stunning beauty, marriage proposals had flooded in.

However, once word spread that she had broken off her engagement with Riser after Kazuki defeated him, most suitors backed off.

"If even Riser couldn't win, what's the point?" they had thought.

Breaking the engagement gave Rias the right to choose her own partner, and she wasted no time picking Kazuki Fuwa her own servant, as her fiancé.

Of course, this didn't sit well with her father, the head of the Gremory family.

Rias had been furious, "That wasn't the deal!", but Kazuki understood why. Despite beating Riser, he was still a newly reincarnated, low-ranked devil. Hardly the ideal consort for the next head of the Gremory clan.

Talks dragged on... until the "Holy Sword Incident" flipped the script.

During that chaos, Rias had protected Kuoh Town from the fallen angel leader Kokabiel, earning massive recognition. On top of that, Issei Hyoudou awakened his new ability, "Transfer," Yumi unlocked her Balance Breaker, and Kazuki himself dealt the finishing blow to Kokabiel.

All of this shot Rias' reputation through the roof—far beyond where it was even before the Riser fight.

Ironically, Kazuki's offhand comment, "You can always rebuild your status later"—had become a reality.

With all that considered, Rias' father grudgingly accepted Kazuki as a provisional fiancé. But the "NO SEX" rule, was still in place.

Well... mostly.

They'd been granted some leniency—as long as things didn't go all the way, a bit of heavy petting was allowed.

Grayfia had come by recently to explain this, completely deadpan, while Rias blushed furiously.

As for Kazuki Fuwa, the guy just wanted to melt into the floor.

Still, the two now had some freedom. That very night, Rias eagerly used her hands to give him a handjob and make him cum. She was surprisingly into it, leaving him a little taken aback. When he asked, she admitted she'd been holding back for too long.

"Come on, it's weird not to get in the mood when you're sleeping next to the person you love," Rias pouted.

She was adorable when she sulked, so Kazuki made sure to return the favor—again and again—until she was breathless.

Rias sometimes felt bad about not letting him go all the way, but Kazuki didn't mind. After all, he was getting plenty of action with Akeno and Yumi.

He'd finally come clean to Rias about it—especially about how things with Yumi had gone all the way. He expected hellfire. Instead, Rias had sighed deeply and muttered, "Yeah, I figured."

She'd known Akeno had feelings for him. And after the Holy Sword Incident, Yumi had been practically glued to Kazuki's side.

Rias Gremory, being from a noble family, was surprisingly okay with the idea of him having a harem, so long as she was the main wife and Kazuki loved her most.

"A lot of my peerage girls carry emotional scars," she had explained. "I want them to end up with someone they can trust... so please, take care of them."

Of course, she didn't want to be neglected either. "But don't forget about me, okay?" she'd whispered, looking heartbreakingly vulnerable.

Kazuki found her too damn cute to resist. That night, he made her cum over and over until she passed out.

'If I want to be officially recognized as Rias' fiancé, I need more big achievements. But honestly, nothing like the Holy Sword- level disaster anytime soon!!' The Guyver boy thought. 

Later, in the bathroom-------------

"I can handle it, Rias!! Don't push yourself," Kazuki said gently.

"I want this. I need this," Rias replied, rinsing the soap from her flawless voluptuous skin under the shower.

As the water streamed off her, she turned, hugging him from behind.

"I want you to make me yours, Kazuki... soon."

He could feel her warmth against his back, the soft press of her massive voluptuous tits, the raw emotion in her voice.

"I'll make it happen…" he promised, squeezing her hand.
