"Yumi!? Why are you here?"
"I saw you coming in, Senpai. I thought this would be a good place to be alone with you… But then I overheard your conversation with Xenovia, so I decided to listen in!"
"I-I see…"
Kazuki felt a chill run down his spine as Yumi casually admitted to eavesdropping without a hint of shame.
"More importantly, Xenovia. You can't just suddenly ask to make a baby like that! That's impossible!"
"Why not? Isn't it just a matter of inserting the male organ into the female organ and having him ejaculate?"
Xenovia's words sounded like they were ripped straight from a health education textbook.
"...Listen, Xenovia. Before having sex, both partners need to prepare themselves! Do you even know what to do?"
"No. I figured Kazuki-senpai would teach me."
"This is something you should study beforehand!! Fine, I'll show you how it's done."
With a confident smirk, Yumi knelt down in front of Kazuki.
"Senpai, excuse me."
After giving a polite warning, she pulled down Kazuki's swim trunks, revealing his growing length.
"Oh… so this is…"
Xenovia's eyes locked onto it with curiosity. But Yumi ignored her gaze and wrapped her fingers around Kazuki's cock, slowly stroking it. With each pump, his shaft grew harder and thicker in her grip.
"Wow…! This is!!"
Xenovia leaned in, intrigued by the transformation.
"See? Amazing, right? But this is just the beginning."
With that, Yumi lowered her head and extended her tongue, trailing it along the rigid shaft.
"Mm… slurp… slurp… mmchu… nmu… chuu…"
"K-Kiba Yumi!? You're actually licking that!?" Xenovia stared in shock, her throat gulping audibly.
"Xenovia, what are you talking about? Lick, suck... You want Kazuki-senpai's seed, don't you? Mmm, lick, slurp... Then it's only natural to serve senpai's cock, right? Slurpp, suck, mmm..."
"R-Really?"
Xenovia's eyes widened in disbelief as she watched Yumi's actions, her face flushing red.
"First, you wet it all over with saliva... Ahh, slurp!"
Yumi took Kazuki's dick into her mouth, moving her head back and forth with practiced ease.
"Mmm, slurp, slurp, mmm... suck, lick!"
Xenovia couldn't look away, her cheeks burning as she witnessed Yumi's skilled ministrations.
"Mmm, slurp~ POP! See? It's gotten even bigger, hasn't it?"
"Y-Yeah..."
Xenovia was stunned. Kazuki's cock had grown even larger than before, now fully erect and ready for action.
'It's... so big! Is something like this really going to go inside me───!?' she thought.
"Come on, Xenovia!! Your turn now."
"M-Me too!?"
Xenovia recoiled slightly at Yumi's suggestion, but Yumi gently took her hand, guiding her to kneel beside her.
"Don't worry, it's not scary!! Here, sit like this..."
"O-Okay..."
With Yumi's encouragement, Xenovia knelt down, her heart racing as she faced Kazuki's throbbing member.
"First, try touching it."
"O-Okay! It's... so hard. And hot"
Xenovia hesitantly reached out, her fingers brushing against Kazuki's length. She slowly stroked it, her breathing growing heavier with each touch.
"See? Hard and hot, that's Kazuki-kun's cock for you. Now, try licking it."
"O-Okay... Gag! Ugh?"
The moment Xenovia brought her lips close, an unfamiliar pungent odor assaulted her nostrils. "Do I really have to lick this...?" She glanced uncertainly at Yumi, who nodded with deliberate slowness.
Swallowing her hesitation, Xenovia tentatively extended her tongue and dragged it along Kazuki's throbbing cock.
"Ugh... ngh... Slurpp—!"
A bitter, numbing taste spread across her tongue, forcing Xenovia to jerk her head back. Her pleading eyes met Yumi's, whose gaze sharpened with a silent command: "Keep going." Resigned, Xenovia leaned in again, tracing her tongue hesitantly over his cock.
"Nn... slurp, chu... slurop... chup, ugh—"
"Mmm, no need to grimace like that," Yumi purred, her lips glistening. "This is Kazuki-senpai's flavor. Well?~"
"Chup... it tastes bad," Xenovia muttered, her face twisted.
Yumi chuckled, lazily swirling her tongue around the tip. "You'll learn to crave it. Just... nn, like this—slurp, chup~" She demonstrated with lewd relish, her cheeks hollowing as she sucked him deeply.
Xenovia stared, unable to reconcile the lewd spectacle before her with Yumi's usual prim demeanor.
"Ah, here's the next step," Yumi cooed, her lips stretching around Kazuki's girth.
"Take him in... nn, ngh... chupo, mmm, chupa~" Wet, gulping sounds filled the cramped storage room—licks, slurps, the slick rhythm of her mouth pistoning his cock.
Yumi's face was in ecstasy as she sucked Kazuki's cock with gusto.
Her eyes were moist, her cheeks were flushed red, and drool was even dripping from the corners of her mouth. Xenovia couldn't take her eyes off her lewd appearance, the complete opposite of the usual pure and innocent Yumi.
'That stoic Yumi... reduced to this? How can she... enjoy something so vile? Is my tongue broken...?'
"Y-Yumi... I'm close," Kazuki groaned, his hips twitching.
"Nnchu... puah~... f-fine," she gasped, pulling away. A silvery strand clung to her lips and his cock before snapping, the lewd sight searing itself into Xenovia's mind.
"Your turn, Xenovia~," Yumi breathed, nudging her forward.
"U-uh... nmmph—!"
Xenovia's lips sealed around his dick, recoiling internally. 'Gods, ugh, it smells! And it's so slimy!?'
However, she couldn't move after taking it in. Seeing this, Yumi let out a sigh and said…
"Senpai, please go ahead and do it!"
With that, she pushed Xenovia's head from behind. Prompted by Yumi, Kazuki began to move his hips.
"!? bufu, mmmph, ugh, slurp!?"
Xenovia gagged as Kazuki's massive cock hit the back of her throat. She wanted to escape, but Yumi held her head firmly in place, leaving her no way to retreat.
The torment of having her mouth ravaged brought tears to her eyes naturally. Xenovia, who had endured countless grueling missions, couldn't believe she was crying so easily.
Now, Xenovia's once pristine face was not only streaked with tears but also smeared with drool and snot. As her consciousness began to blur from the lack of air, she heard Kazuki's urgent voice.
"Fuck… I'm gonna cum!"
'Cum? What?' Just as she thought that, a hot, thick substance shot into her mouth.
Spurt Spurt Spurt Spurt Spurt Spurt…
'What? What is this!? It's hot, bitter, and so sticky!?'
"Swallow it, Xenovia!!"
Kazuki commanded, but Xenovia was horrified.
'Swallow? This!? No way! There's no way I can swallow this!?'
In an instant, her mouth was filled to the brim, and as more semen was pumped into her, Xenovia couldn't hold it in any longer and finally let it spill out.
"Blegh! Ugh, cough, cough, cough!"
Unable to endure it any longer, she pulled her mouth away from Kazuki's cock. As the still-spurting white, sticky fluid splattered onto her face and chest, she coughed violently, spitting out the semen in her mouth.
"Ah, what a waste!"
Yumi's voice could be heard, but Xenovia was too busy desperately trying to spit out the thick, sticky substance filling her mouth. No matter how much she coughed, the viscous fluid clung stubbornly to the inside of her mouth.
"Cough, cough! Wh-what is this?! There's no way I can drink something like this!" Xenovia exclaimed, her voice trembling with disgust.
"...What are you talking about, Xenovia? That's the precious seed of Kazuki-senpai that you were so eager to have," Yumi replied calmly, her tone almost teasing.
"Wha—?! This is it?!" Xenovia's voice rose in shock. With almost no knowledge of sexual matters, she had no idea what semen looked or felt like.
She scooped up some of the sticky fluid that had spilled onto her chest and stared at it intently.
"If you're going to react like that, I can't give you any more of senpai's cum... Senpai, let me clean you up now," Yumi said, her voice soft but determined.
Without hesitation, she took Kazuki's soiled cock into her mouth, her lips wrapping around it tightly.
"Mmm... slurp, suck, lick, lick... gulp, gulp... ahhh~" Yumi's skilled tongue worked diligently, cleaning every drop of his cum from Kazuki's shaft.
She swallowed the remaining essence with a satisfied expression, her actions leaving Xenovia wide-eyed in shock.
"Mmm... slurp, suck... lick... huu. Senpai, you're all clean now," Yumi said, pulling away with a soft smile.
"Good job, Yumi," Kazuki praised, gently patting her head. Yumi beamed at the praise, her eyes sparkling with affection.
"Senpai... Since Xenovia doesn't seem like she can handle it right now, please... put it inside my pussy instead," Yumi pleaded, her voice dripping with desire.
"Alright. Come here," Kazuki replied, pulling her close. His hand slipped into her panties, finding her already drenched.
"Ahhn~ S-Senpai!" Yumi moaned, her thighs trembling as Kazuki's fingers brushed against her soaking wet folds. Her white swimsuit was practically transparent from how wet she was, her body clearly ready for him.
"Looks like you're already prepared, Yumi," Kazuki remarked with a smirk.
"Yes... So please, senpai, thrust your big, hard cock into my dripping pussy!" She begged shamelessly, her voice filled with need.
"Well said. Then here I go," Kazuki replied, pulling Yumi's panties aside to expose her glistening slit. Without hesitation, he pushed his cock inside her wet pussy in one swift motion.
"Ahh~ Nnhaaaaahhhhnnn!!" Yumi's voice echoed as Kazuki filled her completely, her body shuddering from the intense sensation.
"You're still as sensitive as ever. Alright, I'm gonna move now." In that standing position, with Kazuki's cock buried deep inside her cunt, Yumi reached her climax almost instantly.
"Aahh! S-Senpai, this is too deep! You're hitting… Ahhhhnnn!!"
"Yumi, you love it deep inside your pussy, don't you!?"
"Aahhh! Y-Yes, yes! It feels amazing deep inside me!"
The sound of flesh slapping against flesh echoed through the room. Meanwhile, Xenovia stood frozen, watching their intense mating unfold before her.
'W-What is this…!? This is sex!? It's… It's this wild!?'
From Xenovia's angle, she had a perfect view of Yumi's expression. The sweet, innocent image she usually carried was nowhere to be found—each time Kazuki thrust into her, her voice melted into moans of pure pleasure.
"Ahh! Ahh! Ahhh! Senpai! Senpaaai! I'm… I'm cumming… I'm cummiiiinggg!!"
Her body tensed, back arching, and at that moment—
SPLASH!
A clear liquid gushed from between Yumi's thighs.
'D-Did she just… leaked!? No way, Kiba Yumi, you wet yourself at your age!?'
Xenovia, still inexperienced when it came to sexual knowledge, couldn't tell the difference between squirting and peeing.
As she stared at Yumi's trembling body, suddenly—
—Squelch.
A strange, wet sound came from right beside her.
'Huh!?'
When Xenovia looked down, her right hand was already between her legs, rubbing against her own damp entrance.
'W-Whaaaaat!? W-Wait a second! What the hell am I doing!?'
Even after realizing it, her hand didn't stop.
For the first time in her life, Xenovia's fingers explored her untouched folds, and the lewd, slick sounds of her own arousal filled the air.
'W-What is this!? Why does it… f-feel so good…!?'
Overwhelmed by the newfound pleasure, Xenovia's body shuddered—and she climaxed effortlessly.
"Haa… Haa… W-What on earth was that…!?"
Panting, she stared at her drenched fingers, completely stunned by her own reaction. Desperate for answers, she turned to Yumi…
But—
"Mmm—chu, fuun, chuba, aahn! Senpai, Senpai~"
Yumi Kiba was completely lost in the throes of passion, her hips moving rhythmically against Kazuki's as their lips locked in a heated kiss. Her lewd moans filled the air, and the sight of her like this made Xenovia swallow hard, her own hand trailing down to her dripping cunt before moving up to cup her lush breasts.
"Haaahn! Nn, ah, ah, it's amazing, so much! So much is coming—!"
"Kuh, Yumi, I'm almost—"
"Yes! Cum inside my pussy! Fill my insides with your seed, Senpai! Flood my womb with your essence!!"
Slap! Slap! Slap! Slap!
"Yumi, Yumi, I'm gonna cum!"
"Come, come, fill me all the way up—!!"
Splurt, splurt, sploosh!!
"Nnaaaaahhhhnnn!! I'm cumming, I'm cummiiiiing!!"
As Kazuki's thick cock hit Yumi's deepest spot, a torrent of thick, white fluid surged forth, filling her to the brim.
Almost simultaneously—
"Fuuuuuhhhhnnn!!"
Xenovia, who had been pleasuring herself, reached her own climax. Her body trembled as she watched Yumi, who smiled contentedly, her pussy now overflowing with Kazuki's sticky semen.
'Ah, she looks so happy—is this the joy of a woman? Mmn… How wonderful'
With a look of envy in her eyes, Xenovia collapsed onto her back. She scooped up a bit of the residual cum that had splattered onto her chest and brought it to her lips, licking it clean.
'SLURP! How strange…' what she once thought tasted unpleasant now seemed delicious…
'Ah, I've done it!! I ended up doing it with Xenovia and Yumi in a place like this.' Kazuki thought.
Yumi was leaning against him, her breath ragged and uneven, while Xenovia lay sprawled out, her hand still tucked into her swimsuit, having masturbated herself to completion.
"Yumi, I'm pulling out!! Can you stand on your own?"
"Haah, haah… hehe, Senpai, you're still so big~! Are you sure you want to pull out?"
Yumi's sweet voice whispered temptingly.
"I wouldn't mind if you kept going, you know."
It was a tempting offer, but Kazuki knew he couldn't push himself any further, especially with everyone just outside.
"If you've got that much energy, you can stand on your own. Here, I'm pulling out."
With that, Kazuki slowly withdrew his cock from Yumi's creampied, quivering pussy.
"Ahhn! …Ahh, it came out."
Yumi, still unsteady on her feet, leaned against him for support as they moved. From her freshly stretched entrance, thick, white cum dripped down, leaving a trail of spots in her wake.
"You were watching, right, Xenovia? So? This is sex." Sitting beside Xenovia, Yumi spoke with a seductive smile.
"Kiba… Yumi… Something's wrong with my body. Watching the two of you have sex… my body got unbearably hot, and something strange started leaking from… down there. What's happening to me!?"
With teary eyes, Xenovia looked utterly confused, making it clear that she had little to no knowledge of sex.
'Did the church really not provide any form of sexual education?'
"Don't worry, Xenovia! When a woman gets sexually aroused, her pussy gets wet. It's how we prepare to take in a man."
"Is… that so?"
"Yep. You saw how wet I was when I was doing it with Kazuki-kun, right?"
"That's true! You were dripping wet everywhere."
"…Ugh, saying it so bluntly is kind of embarrassing. A-Anyway, it's a natural reaction, so there's nothing to worry about."
"I see… That's a relief."
Hearing Yumi's explanation, Xenovia finally seemed to relax.
"Kiba—no, Yumi. Thanks for explaining. If you don't mind, I'd like you to teach me more from now on."
"Hehe! Just call me Yumi!! We're comrades now, after all."
"Alright, I'll be counting on you, Yumi."
The sight of two beautiful girls smiling at each other was breathtaking—if not for the sticky, white fluid splattered on their bodies, completely ruining the picturesque moment.
They definitely needed a shower.
Just as Kazuki Fuwa was about to suggest it—
CLACK!
"Kazuki, are you here!? This is getting us nowhere, so Akeno and I decided to settle it with a swimming competition…"
Rias Gremory suddenly threw open the equipment room door, but as her gaze swept across the scene inside, her voice dropped to an icy chill.
Behind her, Akeno Himejima peeked in with her usual teasing smile.
"Ara ara, well well~"
However, despite the usual playful tone, there was something unsettlingly ominous about that smile.
