Reincarnated in the World of High School DxD

The alarm on Kazuki Fuwa's phone rang, pulling him awake. He had fallen asleep around 4:30 AM, just as dawn began to break.

Though he'd managed roughly two hours of rest, exhaustion still clung to him.

His gaze drifted to Yumi sleeping peacefully beside him.

Her serene face looked softer, almost childlike, compared to her usual demeanor. The previous night, he'd pushed her far too hard.

Lost in the frenzy of his first sexual encounter since reincarnating, Kazuki had been reckless—especially since it was Yumi's true first time.

Yet, he couldn't fully regret it. A beauty like Yumi, with her flawless features and innocent allure, was someone he'd never even dreamed of touching in his past life.

The memory of her writhing beneath him, moaning uncontrollably, made his morning erection throb even harder.

"Nn… uun…?" Yumi stirred, her eyelids fluttering open as if sensing his stare.

"Good morning!! How's your body holding up?" Kazuki asked, his voice low.

"Ah… Good morning, Kazuki-senpai… Senpai…?" Still half-asleep, she blinked at him in confusion.

But then—

"～～～～～!!"

The memories of last night flooded back. Her face flushed crimson, and she yanked the bedsheet over her head, hiding entirely.

"Hey… Yumi? What's wrong?"

"～～～～～…"

No reply. She was clearly drowning in embarrassment. But Kazuki Fuwa wasn't one to let her off easily.

"Did you… forget what happened last night?"

'N-No, I remember everything!!' Yumi recalled every lewd detail—that was why she couldn't face him.

"Even how you were the one who seduced me?" he added teasing her further. Her body twitched sharply under the sheet.

"Or how you came untouched when I filled your pussy with my cum—even though it was your first time?"

"～～～Huuk～～～" Another jolt, harder this time.

"Or how you drooled and begged, 'More… more…' while riding me yourself?"

"I-I didn't do any of that!!"

Yumi shot upright, protesting indignantly—only for Kazuki to seize her.

"Got you." He pulled her tightly against his chest.

"S-Senpai, you're mean!"

"Mean works!! No need to be shy. You were adorable."

"Uuuu~~…"

She grumbled but gradually relaxed as he stroked her back, her face buried in his warmth.

"Calmed down now?"

"…Yes. I'm sorry, Senpai. I… got carried away…"

When she finally looked up, her cheeks still burned pink.

"Don't worry. It's natural. But seriously—are you okay? Any pain?"

"Huh? Oh… I'm a little sore, but… I'll manage. Probably."

"Hmm… Then maybe this is too much?"

"Too much? What do you— Hyaaaah!?"

Yumi's eyes dropped, and there it was. Kazuki's thick, rigid cock stood fully erect, veins pulsing.

'Eeeeeek!? S-Something this huge was inside me…!?'

Last night, even after multiple climaxes, Kazuki's stamina never wavered.

He'd kept cumming inside her pussy until she passed out, meaning this was her first real look at his monstrous size.

Yumi gulped audibly. Her hand trembled, instinctively reaching toward him—

"Yumi. Let's shower first."

"Eh? S-Senpai…?"

Ignoring her flustered stammer, Kazuki guided her to the bathroom.

And then───

"Haah, ahn! Senpai, there...!"

Kazuki was washing Yumi's body, which was covered in soap suds, with his bare hands. It was inevitable that he would touch various places while washing her. With that excuse, Kazuki caressed Yumi's body all over.

From behind, he kneaded her ample breasts. While they weren't as large as Rias's or Akeno's, they were still more than enough to be considered big, and the sensation of squeezing them, though still slightly firm at the core, gave Kazuki an exquisite feeling.

"Does it still hurt?"　

"Haa, nn! The pain... it's mostly gone, but..."

"But what?"　

"Nnnn!... I-it's a weird feeling like something's tingling up my spine... haahn!!"

As Kazuki teased her stiff, pointed nipples, Yumi let out a moan.　

"That's what it feels like to cum, Yumi."　

"T-to cum...? This is... ah, ahhh!"　

"That's right. Just let it out, let your voice go, let everything out. You'll feel even better."　

"E-even better...?" Yumi gulped.

She was already burning with an unfamiliar pleasure, and if it was going to feel even better than this, she wondered what would become of her. Yumi's heart wavered between fear of the unknown and curiosity.

Eventually…

"Ah, ahh, it feels so good! Senpai, more, do more! Touch Yumi's breasts more───!!"

Perhaps curiosity got the better of her, as Yumi began to voice her feelings openly. Encouraged by her voice, Kazuki inserted his finger into Yumi's vagina.

"Ahhh! Senpai, there... you can't, nnnn───!!"

From within her pussy, the remnants of last night's activities and her own juices created a wet, squelching sound that heightened the sensuality between the two.　

"Yumi!! Do you know what this is called?"

"Huh? H-here is... haa, nnn!?"　

"If you don't know, I'll tell you. It's called a pussy."

"A... a pussy...?"

"That's right. So next time you cum, say───"

"T-that's... impossible!!"

"You can say it, right, Yumi?"

"Uuu…. Yes, I'll."

"Good girl."

After teaching Yumi something, Kazuki kissed her from behind as a reward for her consent.　

"Ah, nn, Senpai... chu, mmmph..."　

"Alright, let's go then?" With that declaration, Kazuki quickened the movement of his fingers.　

"Ah! Ah! Ah! Senpai, Senpai!!"

Using his index and middle fingers, Kazuki delved into Yumi's vagina. It was overflowing with her juices, readily accepting his fingers without resistance. Kazuki didn't just move them in and out; he twisted his wrist, rotating his fingers like a drill, stimulating Yumi's insides.　

"Ahhhh! Senpai, Senpai! I'm, I'm already───!!"

Exposed to such intense movements, Yumi was on the verge of reaching her limit.　

"That's it, Yumi, come like I taught you!"　

"Y-yes!... I-I'm cumming! Yumi's pussy, feeling so good because of Senpai, I'm cumming, aahn, I'm cumming───!!"

PUSHAAAAAAH!!

PUSHAAAAAAH!!

She squirted a large amount of fluid, reaching her climax.　

"Ahhhhh───!!" With a loud moan, Yumi collapsed on the spot.

Before Kazuki's eyes was the voluptuous Yumi Kiba, her ass raised high. Her groin, as proof of her climax, dripped with a copious amount of her juices, and her tight pussy entrance opened and closed as if inviting Kazuki in.

Seeing such a sight, Kazuki was far from unaffected.

Supporting himself, already in a state of readiness, he aimed his thick cock at Yumi's quivering pussy, which seemed to beckon him.

THRUSSSTTT!!!

And without waiting for Yumi's consent, he thrust in all the way to the hilt in one go…
