After shopping, Yumi Kiba brought Kazuki to her apartment. She explained that she had originally lived with Rias and Koneko but decided to move out when she started high school.
Now, standing at the entrance of her cozy one-bedroom apartment, Kazuki couldn't help but feel a bit nervous. It was his first time being invited into the home of a girl living alone.
The atmosphere carried an oddly intimate weight that he couldn't quite shake.
"I'll start cooking, so Senpai, feel free to watch TV or relax."
With that, Yumi tied an apron over her casual loungewear and moved to the kitchen.
Kazuki couldn't stop his heart from pounding as he watched her.
"Thanks for the meal."
"Fufu♪ I'm glad you enjoyed it."
Yumi's cooking was delicious, no exaggeration needed. Rias, despite being raised as an aristocrat, was also skilled in the kitchen, but Yumi was just as good.
As they sipped on tea after dinner, they chatted about various topics—school, their comrades, their past, their future… and then—
"Senpai, thank you… truly."
"You've already thanked me plenty of times."
"But it's because of you that I realized something. The people I lost… they didn't pass away full of resentment. They wished for my happiness. I was able to understand that because of you…"
"…I see."
"Yes. And… Senpai, I've decided. I want to be happy, just like they wanted me to be."
"That's a good thing."
"I thought about what would make me truly happy. And I realized—being with the person I love, that's the greatest happiness I could ask for."
Yumi stood up, her gaze never wavering as she slowly approached the Guyver boy.
"When that thought crossed my mind, the only person who appeared in my heart… was you, Senpai."
"Yumi…"
"I love you, Kazuki-senpai." With those words, Yumi pressed her lips against his.
The kiss lasted about ten seconds before she pulled away, her face flushed a deep red. Still, she smiled with unmistakable happiness.
"Fufu, I finally did it!! …I know Senpai has Buchou, and I understand that. But I can't ignore these feelings anymore. I don't mind being second… Will you love me too?"
Her deep blue eyes wavered slightly with uncertainty, yet they held firm as they gazed into Kazuki's.
"Are you sure? You might regret this later."
"Hehe, it's because you're that kind of person that I fell for you. So please… love me so much that I'll never have a reason to regret it."
Yumi leaned in again, sealing their lips together. This time, Kazuki didn't hesitate. He responded in kind, kissing her deeply, greedily—devouring her lips.
Yumi Kiba's bedroom was filled with a sweet, intoxicating scent.
Kazuki gently lay her down on the bed. Her eyes flickered between anticipation and nervousness. Wanting to ease her tension, he leaned in, capturing her lips once more.
"Ah… Senpai… mm… ngh… nnh… chuu… nn—"
As their lips melded together, Kazuki slipped his tongue into her mouth, dominating her completely.
Wet, squelching, lewd sounds echoed between them as his tongue tangled around hers, claiming her without mercy.
"Haa... nn, chu, nchu, nna, nn... gulp, gulp, nnn! Haa"
Yumi's toes stretched out straight. It seemed she had reached a slight climax. 'She must be quite sensitive.'
"Haa, haa, se-, senpai...."
"I'm going to undress you, Yumi." Her cheeks flushed red as she nodded slightly.
Kazuki carefully unbuttoned her blouse one by one, revealing a mountain range larger than expected. The vibrant pink peaks stood out against her white skin. The peaks were already standing firmly erect, 'So Yumi's not wearing a bra!!'.
"Yumi....?" Kazuki wondered as he moved down…
"Ah, well, I thought underwear might get in the way when undressing... uu~ so!"
It seemed Yumi had been prepared from the start, having removed her underwear when she changed clothes.
"Then, perhaps down there too?"
As Kazuki said this, he slid his right hand under her skirt, and a distinct, wet squelch sound could be heard.
"Hinn!?"
Startled by her own involuntary voice, Yumi covered her mouth with both hands. Hearing her voice, Kazuki smirked mischievously.
"Hmm, so Yumi is the kind of girl who cooks without a bra or panties, huh?"
"Ah, well, that's..."
"With her nipples this hard..." Kazuki pinched her erect nipples tightly.
"Hin!?"
"And this dampness between her legs..." He lightly traced his finger along her slit.
"Haan!!"
"I had no idea Yumi was such a naughty girl."
Yumi's face turned bright red from his teasing, her body burning with shame.
The sight of her on the verge of tears from embarrassment was unbearably erotic to him. Just as she seemed about to cry, Kazuki whispered,
"But you know, I really love naughty girls like you."
With that, he showered her with kisses.
"Aahn! Se-, senpai... ahn."
Kazuki trailed his lips and tongue down her body—her forehead, cheeks, lips, chest, nipples, and navel—gradually moving lower.
Yumi's entire body glistened with his saliva, completely melting under his touch. Sensing the right moment, Kazuki lifted her skirt. The heat and the dense, feminine scent trapped inside hit him directly.
"Ah, s-senpai, not there!" Yumi reflexively cried out, but that was all.
Her thighs were drenched with transparent nectar, a flood of arousal. And her entrance was slightly parted, continuously overflowing with her juices.
Kazuki swallowed hard at the overwhelmingly erotic sight before him.
"...Damn," he muttered, unable to hold back his admiration.
"Uuuu~~" Yumi let out a cute moan as Kazuki couldn't resist any longer. And buried his face between her thighs.
"Hyan! Senpai, not there... ah! No! That's... it's dirty... aahn!" Yumi protested, but Kazuki ignored her pleas.
Kazuki licked and sucked at her most intimate area, his tongue tracing the vertical slit, lapping up the overflowing love juice, and probing the tiny entrance. He peeled back the hood of her clitoris, exposing the sensitive bud, and gently nibbled on it.
"!? Hii, hyaaaahhnnn!!" Yumi's body jerked violently.
Splaaash!!
Squirrttttttttt!!
With a loud, wet sound, Yumi Kiba squirted, reaching her climax.
"Haa, haa, ah, uu..." Her eyes were glazed over, her breathing ragged as Kazuki lifted his face, drenched in her love juice.
"Yumi..." Kazuki murmured.
"Nnaah, Sen...pai... mmu, chu..." Yumi responded, her hands instinctively wrapping around the back of his neck as he kissed her deeply, their tongues intertwining.
"Nn──fen, puai... chu, chup... nn..."
"Yumi... are you ready?" he asked, pulling away slightly to look into her eyes.
Yumi, regaining some clarity, nodded softly.
"Yes. Senpai, please... come inside me..." she whispered, spreading her legs wider in invitation.
Kazuki quickly shed his pants and underwear, revealing his fully erect cock. He rubbed it against her slick entrance, coating it thoroughly with her juices.
"Ah, Senpai..." Yumi moaned softly.
"Here I go, Yumi," Kazuki said, positioning himself and thrusting his throbbing dick into her tight entrance.
"Nn, guuuuhhh!?" Yumi's entrance was narrow and tight. Despite how wet she was, Kazuki's size made it difficult to push in.
Yumi winced in pain, her face contorting.
"Yumi... if we keep going like this, it'll just hurt. I'm going to push in all at once, okay?" he warned, his voice strained with restraint.
"Y-yes───!"
Once he pulled his shaft back slightly from her entrance, then kissed Yumi deeply while beginning to fondle her breasts.
"Fuwa!? S-senpai? ...nchu, ah, nnaa..."
Yumi, who had been bracing for pain, was instead overwhelmed by unexpected pleasure, her body writhing.
"Haa, haan! ...Senpai, nnaan!"
Seeing that Yumi had relaxed enough, Kazuki thrust his cock into her pussy in one swift motion.
Slurpp, Snaappp, buchii!!
"Nnaaaaahhh!!!"
For a moment, he felt resistance, but he pushed through without hesitation, feeling his tip hit deep inside her.
"Haaah! Haaah! Ah, uuu──"
Yumi seemed to be in considerable pain, her breathing ragged as tears and drool streamed down her face.
"Did it hurt, Yumi? You did well." Kazuki held her tightly in his arms.
"Senpai... did I do it right?"
"Yeah, it's all the way in."
He waited for Yumi's pain to subside, stroking her head and caressing her body gently. After a while, Yumi's expression softened, and she looked up at him.
"Um, Senpai... the pain has mostly gone away now, so... you can move, if you want."
"Are you sure?"
"Yes. Besides, it must be hard for you to stay still like this, right?"
As she said, even though he was just inside her, her tight walls were squeezing him so intensely that he felt like he might climax just from that.
"Alright. Here I go."
"Y-yes! Nn, nnnn!!"
Kazuki pulled his dick almost all the way out, leaving only the tip inside, then thrust back in deeply. He repeated this motion, slowly pulling out and then pushing in forcefully. With each thrust, Yumi's insides began to loosen.
"Nna, ann! Nnnn! Haan! Ann!"
Yumi's pussy walls were still tight and constricting, gripping him tightly with every thrust.
Though Kazuki had experience in his past life, this was his first time having sex since being reborn as "Kazuki Fuwa."
After nearly twenty years, he was drowning in the pleasure, and despite it being his first time in this body, Kazuki began thrusting into Yumi's pussy with increasing intensity.
"Ahhh! Senpai, senpai! I-I don't know this feeling! Ahhn! Senpai, I-I'm already───!"
On the other hand, Yumi, despite it being her first time, seemed to be feeling it intensely. She let out moans of pleasure while tightly squeezing him.
Slap! Slap! Slap! Slap!
The sound of flesh slapping against flesh echoed throughout the room.
Squelch! Splurt! Squelch! Splash!
Yumi's love juices, the blood from her broken hymen, Kazuki's pre-cum, and their mingling sweat—all their fluids mixed together, creating a lewd symphony.
"Yumi, Yumi! Yumi!! Kuuh!!"
"Senpai, senpai! Senpai!! Aahhhnnn!!"
Kazuki was already at his limit. All he could think about was filling the woman before him with his seed.
"Yumi! I'm going to cum! I'm going to fill you up inside!!"
"Cum inside me! Senpai, fill me up, cum inside my pussy!!"
As Kazuki's cock pushed deep into Yumi's innermost depths, he released a torrent of hot semen…
Splurt
Splurt
Splurtt…
"Nnaaaaahhhhhhhh───!!"
With a scream, Yumi's body arched sharply, stiffening in ecstasy.
"Haa, haa, Yumi...."
"Haa, haa, Kazuki, senpai...."
Gazing at each other breathlessly, they pressed their lips together once more.
"Nn, chu, Kazuki-kun... I'm so happy right now...." Yumi smiled a pure, blissful smile as she spoke.
"Yeah, me too."
They held each other tightly.
But then...
"Ahhn ... Um, senpai?"
"Uh, well...."
Kazuki's cock, which should have softened after cumming, remained hard and erect, still pressing against Yumi's inner walls.
"Um... don't men usually, you know, get smaller after they finish?"
"Normally, yeah, but I'm... I can't be satisfied with just one time!!"
One of his reincarnation perks was a "Robust Body." Kazuki had asked for a strong, healthy body resistant to injury and illness, but the goddess had gone above and beyond, granting him high physical abilities, athletic prowess, and, as a side effect, an overwhelming stamina.
Thanks to that, no matter how many times he came, he never grew tired—a troublesome state of affairs.
"Now that you're my woman, you better be ready for more than just one or two rounds, got it?"
"I-I wouldn't have it any other way! ... So, should we go again now?"
"You said it. Don't regret it!"
"Yes. Ah, but...."
"But what?"
"... Please be gentle with me."
Yumi Kiba looked so unbearably cute at the moment that Kazuki couldn't help himself, and they dove straight into round two.
That day, Kazuki Fuwa came inside her pussy five times and on her body three more, leaving the blonde busty completely unconscious.
In the end, he couldn't keep his promise to be gentle.
They didn't fall asleep until the sun had already risen.
