Reincarnated in the World of High School DxD

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.

"Ohoooohhh~~~~!!" Yumi let out a strange cry as she climaxed once more.

The tight, firm walls of Yumi's pussy seemed to have loosened considerably from their lovemaking since last night.

While the sensation of tightness remained, what was once painfully constricting had now become pleasurably snug. Kazuki took this as a sign that Yumi's body had fully accepted him, and spurred on by this joy, he quickened the pace of his thrusts.

"Ah! Ah! Ah! Ah! Senpai, Senpaaai~"

"That's it, Yumi! Let it out! Be honest with your feelings, let your voice rise with your pleasure!!"

Slap! Slap! Bang! Slap!

The sound of flesh meeting flesh and the mingling of their moans echoed loudly through the morning bathroom.

"Senpai! It feels so good!"

"Where? Where does it feel good!?"

"Nnhaaah! D-deep... deep inside feels so good!"

"Deep? Like this!?"

Kazuki pulled out almost completely, then thrust back in with force, aiming for the deepest part of her pussy. The firm resistance against the tip of his cock told him he had reached her cervix.

"Ahhhh!! That's it, yesssss!!"

The tip of Kazuki's cock pressed against Yumi's cervix.

Splashhh!!

The impact caused Yumi to squirt once more.

"~~~~~~~~~~~~!!"

Yumi let out a soundless scream as she reached yet another climax, losing count of how many times it had been.

"Haah, haah, haah, haah..."

Breathing heavily, Kazuki observed Yumi. Though she was clearly exhausted from being brought to climax so many times since last night, her vaginal walls still tightly gripped around his dick, pulsating as if begging for more.

As Yumi grew more radiant with each climax, Kazuki gulped audibly.

"Haah, haah, haah... ah, nn, Senpai..."

Kazuki stroked Yumi's smooth buttocks, drawing her attention back to him.

Slap!!

"Haaahhnn~!!"

He began thrusting into Yumi's depths once more.

"Senpai! I can't take it anymore!? If you keep going... I'll go crazy!!"

Ignoring her cries, he relentlessly pounded against her cervix, as if trying to mold her insides to his shape.

"Senpai, Kyaaaaaaah! I'm cumming! Yumi's cumming agaaain! I've been cumming the whole time ahhhhhhhh!"

Meanwhile, Yumi, having just climaxed and not yet come down from her high, was thrust back into a continuous state of orgasm. In this state, everything felt overwhelmingly pleasurable, and she could only submit to Kazuki Fuwa's relentless pace.

In the doggy-style position, Kazuki gripped Yumi's breasts and continued to shake his hips vigorously.

"Ah! Ah! Nnnn! Hyyaaaahhnn!!"

"Yumi, Yumi! That's it, your pussy feels so fucking amazing!!"

"Senpai! Me too! Your cock feels so good inside me!!"

Slap! Bang! Slap! Slap!

"Yumi! Yumi! Yumi!!"

"Senpai! Senpai! Senpai!!"

Her womb was pounded relentlessly, and Yumi squirted repeatedly, her climax unending as she continued to orgasm. Her face, slack with ecstasy, radiated a sensuality unimaginable for a seventeen-year-old girl.

The bathroom, once fragrant with soap, now reeked of mingled sweat and the pungent odor of sex. The thick, primal scent only heightened their arousal.

"Fuck, Yumi! I'm close…! I'm gonna cum…!"

"Yes! Cum inside me! Fill my pussy with your semen, Senpai…!!"

"Yumiii!!"

"Nnnaaaaahhhh~~~!!"

Splurt! Splurt! Spluuurt!

Kazuki's cock, pressed deep against Yumi's cervix, erupted violently. Thick, hot streaks of white juice shot into her insides with such force it seemed intent on reaching her very core.

"Ahhn! So… hot… filling my belly…"

Overwhelmed by the most intense climax she'd ever experienced, Yumi trembled as she felt Kazuki's heat flood her from within.

Then, blissfully, she collapsed into unconsciousness…

Yumi Kiba was a beauty so striking that every head turned when she walked down the street.

Though countless men (and women) had confessed to her, she'd never shown interest in romance. Her resolve to protect Rias as her loyal [Knight], coupled with her burning hatred for the Holy Swords, left no room for love.

Yet Yumi's defenses crumbled for Issei. Though infamous at school as one of the "Pervert Trio" (and rightfully so—he'd once peeked at her changing), as a fellow servant of Rias, she found him unexpectedly earnest. His habit of staring at her chest was irritating, but his heart was true.

That's why she'd defied Rias to help him and Koneko rescue Asia. But the mission failed. Asia died, triggering Issei's awakening as the Red Dragon Emperor.

After he defeated the fallen angel Raynare, Asia was reborn as Rias's [Bishop], and all seemed resolved—or so it seemed.

However, Raynare escaped, resulting in a new victim. Yumi's classmate, Kazuki Fuwa. By the time Yumi's group tracked Raynare down, Kazuki was already seriously injured and was on the verge of losing his life.

Rias destroyed Raynare on the spot and saved Kazuki by reincarnating him as a devil using an [Evil Piece].

Until the Rating Game against Riser Phoenix, Kazuki had been a quiet, unremarkable presence. But that game shattered everyone's perceptions.

His incredible martial arts skills and the power of that [Guyver] which served almost as a sacred gear or even more allowed him to annihilate four of Riser's servants in seconds.

Even Yumi, who witnessed it firsthand, struggled to believe it. This was no ordinary high schooler. 'What life had he lived to fight like this?' For the first time, Yumi felt curiosity—no, desire—toward a man.

However, after the game, Rias showed more interest in Kazuki than her. Determined to support her master's budding romance, Yumi buried her own feelings.

Yet his actions again during the Holy Sword incident—protecting her when she tried to leave Rias's peerage, helping her rediscover her bonds with her comrades, reclaiming their crystallized unity—all struck Yumi's heart.

Before she knew it, the feelings she'd suppressed had bloomed into full-fledged love.

Though she acknowledged her emotions, Yumi, with zero romantic experience, had no idea how to act. Overhearing classmates gossip about their boyfriends, she resolved to confess. To her surprise, Kazuki accepted her feelings.

That same night, she gave him everything.

Having lost her virginity less than ten hours prior, a complete novice who'd never even masturbated, Yumi endured Kazuki's relentless, almost cruel passion.

However, even as he claimed her body, she welcomed his semen deep inside her pussy, drowning in euphoria unlike anything she'd ever known.
