While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 69: The Growing "Love" / The Recommendation of the "Five Creampie Principles"

Chapter 69: The Growing “Love” / The Recommendation of the “Five Creampie Principles”

In the Onodera family’s hallway, illuminated by light, Yuu straddled me, her lower half bare, gazing down.

“Ren-chaaan~♥♥♥♥”

The glint in the depths of her black eyes shone with maddening intensity, bewitchingly radiant.

Narrowing those eyes lovingly, with a loose, sloppy smile, Yuu…

“Watch my pussy swallow your cock!♥♥♥♥”

She whispered in a sweet voice.

“Nfu!♥♥♥♥ Your cock just twitched!♥♥♥♥ It twitched!♥♥♥♥”

“…”

…She’s deliberately using lewd words, having learned they stir the deepest parts of me—my male desires.

“Nfu!♥♥♥♥ Nfu!♥♥♥♥ Nfufu~!♥♥♥♥”

Yuu tucked her long hair, dangling from her temples, behind her ear.

Grinning gleefully, like a child plotting mischief, she…

Placed two fingers—index and middle—along her slit.

“Look!♥♥♥♥ Look at it!♥♥♥♥ Please, look!♥♥♥♥”

“I’m looking.”

Spreading her slit with her fingers—kupa—she wiggled her hips, rubbing my erect penis against the pink flesh around her vagina.

“Kupa!♥♥♥♥ Kupa!♥♥♥♥ It’s going in!♥♥♥♥ Look, it’s going in!♥♥♥♥”

“…!?”

A provocative sight.

Her melted expression, sweet voice, lewd words, lascivious movements.

Relentlessly stoking my arousal.

Her joy, her heightened emotions, sent electric shocks straight to my spine before penetration.

My penis grew even harder.

And Yuu, sensing my excitement through direct contact, wasn’t oblivious.

“—Ren-chan!♥♥♥♥ You’re excited!♥♥♥♥ For me!♥♥♥♥ Haa!♥♥♥♥ Amazing!♥♥♥♥ I love you!♥♥♥♥”

Grinding her hips—kui-kui—rubbing her vaginal flesh against my penis’s tip—guri-guri.

Drenching my penis with honey overflowing from her vaginal opening—her love juices.

“Here we go!♥♥♥♥ Itadakimaasu!♥♥♥♥”

Holding my penis with one hand—not the one spreading her slit—she slowly lowered her hips…

“Nn!♥♥♥♥ Nnuu~!♥♥♥♥—”

“—Uh!?”

At first, there was intense resistance.

“—Ah, huh!?♥♥♥♥ It… won’t go in!♥♥♥♥”

Her pussy, with sparse hair clinging to it, its inner vaginal flesh glistening slickly, was drenched inside and out.

Dripping honey, exuding a thick female scent.

Twitching—hiku-hiku—moving lasciviously, eagerly awaiting male intrusion.

“—Aha!♥♥♥♥ It’s… so big…♥♥♥♥”

Her narrow vaginal opening, as if rejecting my penis, clamped tightly—kyu-kyu—pushing back even the tip.

“I want it in!♥♥♥♥ I want you inside!♥♥♥♥ Nooo!♥♥♥♥ My pussy!♥♥♥♥ It’s too happy, clenching too much!♥♥♥♥ It’s bad!♥♥♥♥ If this keeps up…!♥♥♥♥ It won’t work!♥♥♥♥”

“Yuu…?”

Our genitals were aligned, ready to connect deeply.

But her excitement or tension made her vagina clamp shut, spasming lightly—keiren.

It seemed impossible to accept my penis.

Frustrated by the tip barely grazing her entrance, she placed both hands on my chest, gradually applying her weight.

“…Nooo… This way, your cock can’t get inside me…”

She furrowed her brows, looking at our unjoined parts with a sad, pained expression.

“If this keeps up!♥♥♥♥ I won’t get creampied!♥♥♥♥ Ren-chan’s child!♥♥♥♥ I can’t get pregnant!♥♥♥♥”

“Hey.”

…This is bad. Her stress from failing to insert skyrocketed, pushing her to the edge.

Despite my repeated warnings against pregnancy.

She was spiraling, fixating on pregnancy again.

“No…♥♥♥♥ Nooo…♥♥♥♥ I need it inside!♥♥♥♥”

“Kuh…!”

Placing both hands on my chest, she rocked her hips repeatedly.

With my glans pressed against her clamped entrance, moving every which way—front, back, left, right, up, down.

It was just shallow kisses—chu-chu—of my penis against her entrance, no penetration.

…My glans grazed her slick vaginal mucosa, feeling good for me alone.

But no penetration. I wanted to be inside her, and so did she.

This was torture.

“Huh!?♥♥♥♥ What!?♥♥♥♥ Really!?♥♥♥♥ It won’t… go in!?♥♥♥♥ …No way…”

“Yuu?”

Her sloppy smile turned sad, despairing.

Faced with an unexpected setback, she whimpered like a lost child, her voice trembling, on the verge of tears.

“What do I do…!?!?”

“Yuu…”

Her expression turned pitiful, pale, her body and voice shaking as she looked at me.

She was deeply shaken.

The girl who proudly spread her slit and wiggled her hips moments ago was now dejected, almost pitiable.

Despite her erotic appearance and the decadent situation, I wanted to cheer her up, to reassure her. I placed a hand on her cheek.

“Yuu. Calm down.”

“Ren-chan…”

She gazed down with teary eyes.

I placed my other hand on her waist, gently shifting her to ease the insertion-ready stance.

My penis nearly got caught in her butt crack… I wish my son would read the room and relax, but whatever.

Looking up at her, I met her eyes directly.

“We have time. Take it slow. I’m not going anywhere. We’ll get there, like always, soon enough.”

“Okay…”

Yuu nodded obediently, collapsing onto me.

Her soft breasts pressed against my chest.

Soft. Warm.

She rested her chin on my shoulder, our heads brushing past each other. Her long black hair swayed, tickling my neck and chest.

“…I’m sorry… it’s not working…”

“Don’t worry. If we apologized for every little thing, I’d be… nah, that’s a pointless argument.”

“…”

It’s true things aren’t going smoothly.

I developed impotence from a minor incident, then cured it, only for Yuu to have vaginal spasms, making sex impossible.

To the world, it’s a string of miracles, rare events. It’s thrown Yuu’s plans off, leading to outcomes far from her ideals, leaving her frantic.

Add to that Yakko Tsukimi’s mysterious advances, something between Shiori and Yuu, and the shady student council invitation.

It’s no wonder Yuu, who’s loved me so steadfastly, is faltering.

Just the other day, when I apologized for my impotence, she encouraged me with, “Let’s overcome it!♥”

“…Why isn’t it working…?”

That Yuu was now faltering.

It made me sad too.

“It’s okay if it doesn’t work. Not everything goes perfectly the first time.”

“Maybe… but everyone… keeps interfering with me and Ren-chan…”

“…”

Interfering, huh.

Obstacles, things blocking the way.

I don’t know Yuu’s ideals in detail, but guessing roughly, there are plenty of challenges.

…It’s not someone else’s problem.

If Yuu can’t handle it and spirals into erratic behavior, it could make us both unhappy.

Above all, it’s unfair to her.

She’s done nothing wrong.

“…”

“—Nn!?♥”

I hugged Yuu tightly.

Her frame, delicate compared to mine, still had muscle, warm at its core, with a strong pulse of life.

…I hugged her gently but firmly, careful not to hurt her.

“R-Ren… chan…?♥”

She looked at me, confused, as I let her feel my strength and warmth.

Matching her strong pulse with my own.

Showing her I fully accept her love.

…I felt a response.

Not just my ego—I’m sure of it.

Her feelings, my resolve, reached her.

That should be enough… but now, it’s time to push.

“—Yuu.”

“Hya!?♥ Yes!?♥”

She let out an odd squeak, trembling—pikun—staring at me up close, her face flushed but dreamy, eyes narrowed, lips parted, exhaling softly—haa…♥

…I’ve expressed my feelings through looks and sometimes touch before.

But maybe I need to keep showing it, repeatedly, for her to truly feel it.

It’ll take persistence.

“Let’s overcome this. Together.”

“~~~~!?!?♥♥♥♥ Huh!?♥♥♥♥”

I said it up close, but she was so flustered I wondered if she heard me.

“We have time. No need to rush. So don’t be sad, Yuu. Maybe we should even enjoy these moments?”

“~~~~!?!?♥♥♥♥ R-Ren-cha…!?!?♥♥♥♥ Nnnuuu~!?!?!?♥♥♥♥♥”

Her eyes widened, trembling oddly—pikun, pikukyun—in my arms, shaking irregularly for a while.

“…!?”

Her butt, sandwiching my penis, moved seductively—guri-guri—pressing against it, the sudden stimulation nearly making me moan.

Haa… Yuu’s butt is so soft, so good.

…

I want to penetrate her too. Obviously. Normally, I wouldn’t hold back, nor would I need to…

But now, unable to penetrate, unable to have proper sex, she’s the one hurt this time.

“What’s wrong, Yuu… well, never mind.”

So, to avoid hurting her, I tilted my head, feigning calm.

“I’m not going anywhere, like I said. This time together isn’t slipping away. Besides, isn’t it nice to just cuddle like this?”

“…Okay.”

She nodded solemnly, seemingly comforted.

And then…

“…”

“Yuu…?”

“…”

What was she thinking?

What crossed her mind?

She went expressionless.

Staring at me—jii.

“…”

“Yuu? Yo.”

Her deep, abyssal eyes.

“…”

Eyes holding a light so intense, so maddeningly strong.

“…”

Staring straight into me.

“Yuu? What’s up?”

I wouldn’t call her stillness creepy, but staring at my face, my eyes, endlessly—there’s nothing that interesting.

“Yuu. Something on my face?”

I worried briefly about oyakodon splatter. But she’d have pointed it out by now.

…And then.

“…Yeah… yeah, you’re right.”

Yuu nodded, as if deeply convinced of something, shifting her gaze away.

“Yeah… yeah… haaaa~”

Like someone holding their breath too long, or releasing tension, she exhaled long and slow on my chest.

…And then.

“Suuuuuuuuuuu…♥♥♥♥”

“!?”

Burying her face in my chest, she inhaled deeply.

“Haaaaaa…♥♥♥♥”

Exhaling again.

“Suuuuuuuuuuu…♥♥♥♥ Haaaaaa…♥♥♥♥”

Inhaling deeply, exhaling.

Repeating it, face buried in my chest.

Guess she’s back to her usual self.

…Meanwhile, her hot breath was warming my chest.

Her inner heat could almost burn me.

“…”

“Ren-chan.”

She called my name calmly, casually.

Her voice was muffled, face pressed against my chest.

Compared to earlier, her tension and slight trembling were gone, far more relaxed. Relieved she was back to normal, I responded.

“Hm?”

“…”

Why’d she call my name?

Waiting for her to continue…

“I love you.”

“Yeah. I love you too, Yuu.”

After a long pause, that’s all she said, so I replied instantly.

Her face, buried in my chest, was hidden…

Her “I love you” lacked a subject, but it’s probably for me, right? If it was for something else, that’d be embarrassing… no, wait, that makes no sense. Too out of context.

Don’t be so insecure, me. Have some confidence.

I’m not that dense. My gut’s right. Her “I love you” is for me, statistically probable… not arrogance.

I want to believe that.

“I love you.”

“Yeah. I love you too, Yuu.”

She’s still at it.

Breathing through my thin short-sleeve shirt like a mask filter.

I just endure her hot breath… but is she okay? Won’t she pass out from oxygen deprivation…?

“I love you.”

“Yeah. I—”

“I love you.”

“I—”

“I love you.”

“Me too.”

“Ren-chan.”

“Hm?”

“…I love you so much.”

“Yeah. I love you so much too, Yuu.”

Her voice was calm, but…

“Ren-chan.”

She lifted her face suddenly.

Her expression—expressionless.

“Ren-chan.”

“Hm?”

“I love you. I adore you.”

“Yeah. I love you, adore you too, Yuu.”

Expressionless.

Flat voice.

Her emotions were hard to read, but if anything, her expressionless face seemed faintly sad.

No surprise.

It’s that.

She’s suppressing her emotions, on the verge of going all out.

…Uh-oh?

“Ren-chan.”

“Hm, hm? W-What is it…? Spill it.”

A chill ran down my spine as I met her gaze. My words came out weird.

“Ren-chan Ren-chan Ren-chan Ren-chan—”

“W-What’s up?”

I’ve learned from experience.

At times like this.

In this state, she’s bound to say or do something wild.

Her long black hair flowed to the floor at the edge of my vision.

She opened her mouth, voice clear and loud.

“I’m going to bear your child, Ren-chan.”

“…Huh?”

Looking up at her face, so close as she gazed down, my mouth fell open—angu.

“I’m going to bear your child.”

“…Huh?”

“I’m going to bear your child.”

“…You’re going to bear it?”

“I’m going to bear it.”

“I see… I see?”

…Umm, okay.

Bear it… huh.

…“Bear it” means what?

It means giving birth to life. Creating a new life.

I see.

…No, wait.

Not I see.

Get it together.

Don’t escape reality, me.

“Bear it…?”

“I’m going to bear it.”

“Bear it, as in…?”

“I’m going to bear your child, Ren-chan.”

“???”

A swarm of question marks flooded my mind.

When? At what point? In the future? If it’s about the future, she doesn’t need to confess her love again—we’ve already promised a future together, talked about it countless times. Or is this just another expression of love? Surely it’s not a serious declaration of intent—

…And then, the conclusion my brain reached.

No, that’s not it.

This is that.

Yuu’s rampage.

“…Ren-chan, you’ve probably already seen through me.”

Yuu spoke casually, as if chatting about the weather.

“If I had to stop taking the pill, I was ready to act immediately. The medicine Mom hid deep in her bedroom… it’s powerful stuff that makes rationality vanish for twenty-four hours. If someone tried to steal you, Ren-chan, I was going to make you take me by force, and then stop the pill.”

“Wha…t…?”

Stop the pill…?

Stop the pill…?

Like, “Yo, we’re pill-free buddies, lol”?

Is that a new definition of friendship?

…Honestly, I must’ve looked like a total idiot.

To think Yuu was seriously planning this.

That she had concrete preparations to make it happen.

“Yuu, wait—!”

“Haa… I can’t anymore, Ren-chan. I can’t hold back. My womb’s at its limit. If I don’t get pregnant with your child right now…”

“P-Pregnant…?”

“I’m gonna get pregnant.”

“That’s the same thing!”

A clammy sweat trickled down my back.

This time, it’s different.

I was certain.

Yuu was deliberately letting go of the reins, the shackles on her heart.

Slowly, her love juices—almost certainly from her vagina—clung to my crotch.

Her overflowing honey seemed ready to drown even my balls.

…Even now, my son stays lively.

We’re having a serious talk.

Be quiet… sit down… sit!

…Tch, rebellious phase.

“I’ve heard tons of stories from Mom about marrying young. The struggles too. But with you, Ren-chan, I’m sure it’ll be fine.”

“What’s fine!?”

“I’m ready. I’ll fight.”

“Fight!? Fight what!? I’m not that ready yet!”

…Whoa, whoa.

A rampage like never before.

Her tension—her pregnancy desire—shot up at terrifying speed.

Only I could catch it… well, maybe not.

She exuded an unmistakable, overwhelming pressure.

“The pregnancy test… I tried it last night, and it was negative. I kept waiting for that magical line in the window, but it betrayed me.”

“Of course! Pregnancy would be a disaster—wait, you’re on the pill, right!? A test!? Hold on, I can’t keep up!”

So much information.

“Yeah, I’m on the pill, so it’s obvious, but… it was too early for the test anyway, no way it’d show…”

She looked pensive, but I was relieved she wasn’t pregnant.

Relieved… right? She’s not pregnant… right?

…Wait, can tests really not detect it yet…?

“But I imagine it. You, my wonderful husband, and me, living a modest but happy married life.”

“Tch, that’s…! I’m saying it’s too soon—!”

“…Y-Yeah, you’re right.”

“R-Right…!?”

She seemed to acknowledge my point.

“So, Ren-chan, when should we have the ceremony? If you have preferences, I’ll prioritize them.”

“What did you just nod to!? Too soon! Way too soon!”

The conversation zoomed past at sonic—no, light—speed.

I felt left behind in some unknown place. Total Interstellar vibes.

“I love you so much, Ren-chan, it’s driving me crazy.”

“You’re already crazy! You’re super weird right now!”

“Exactly. I’m already crazy. So you’ll have to take responsibility and marry me.”

“Everything you’re saying—context, logic—it’s all a mess! Get it together, Yuu!”

“Of course I’ll get it together. I’ll definitely get pregnant, so don’t worry.”

“That’s not what I meant! ‘Definitely get pregnant’ is the result of not using protection! All I’ve got is worry!”

“Sorry, Ren-chan, but I can’t hold back anymore.”

“Please hold back! Just that part, please!”

“No. Pregnancy started~”

“This isn’t chilled noodles! Don’t start pregnancy like it’s a new menu item!”

…The topic’s heavy, but the vibe’s too light.

If I let my guard down, she’d probably get pregnant instantly.

…At this point, maybe I should grab a condom, sneak it on during sex—

“Just so you know… if you use a condom, I’ll get pregnant with your child immediately.”

“—!?”

Did she read my mind!?

But condoms aren’t the only way to prevent—

“If you don’t cum deep in my pussy, toward my womb—if you cum anywhere else, I’m ready to get pregnant instantly.”

“Y-You…!”

My voice trembled.

…This feeling, this sensation, was a first.

“Five times a day is the guideline.”

“That’s a lot! Too much! Five times is—!”

“No pulling out. Violation means instant pregnancy.”

“!?”

Yuu started saying bizarre things.

The words were heavy with kanji, but the content was utterly brainless.

“No masturbation. Violation means instant pregnancy.”

“Y-You, seriously, your head’s—!”

“No cheating. Violation means instant pregnancy. You’ll live with me alone on a deserted island forever.”

“I won’t cheat! But what you’re saying is terrifying…!!”

Somewhere, the calm part of me nodded, “Yeah, cheating’s a serious crime.”

“No condoms. No pulling out. No masturbation. At least two ejaculations a day. Cheating is forbidden, and violation means immediate punishment: abduction to a deserted island for an inconvenient yet happy life. If you want to be Adam and Eve on a remote island, that’s fine too.”

“‘Fine’ my ass! Thanks for dropping the ejaculation count, though!?”

Maybe she’s showing some compromise, regaining a bit of rationality.

If so, maybe she’ll listen a bit more.

“These are the ‘Five Creampie Principles’ from now on.”

“Here comes another weird one! What’s with the ‘Five Creampie Principles’!?”

“As long as we follow these ‘Five Creampie Principles,’ you and I are protected from unintended pregnancies. Don’t worry.”

“Hm? So, if I creampie you, you won’t get pregnant. Got it… wait, what?”

I almost relaxed.

But then I paused.

Her phrasing caught my attention.

“‘From unintended pregnancies’…?”

“Yes.”

Expressionless, she looked into my eyes and nodded grandly.

…Can she drop the robotic polite speech already?

With her blank face, it’s getting genuinely creepy.

“—So, rest assured, Ren-chan, you can confidently get me pregnant head-on.”

“Of course!?”

I felt left behind by my own retorts. The right one would’ve been, “So you’re determined to get pregnant no matter what!?” I’m messing up my responses.

It’s a bizarre sensation, like my brain’s going haywire. “This must be what brainwashing feels like,” I marveled.

…No, I’m already going crazy.

“I want to make you mine, Ren-chan.”

“…”

“More than anything, I want you to make me yours, completely, forever.”

“…”

“My feelings… they won’t stop.”

“…”

Stared at expressionlessly.

Spoken to flatly.

I was speechless.

I couldn’t retort.

I knew she was serious.

More than ever, constantly updating “more than ever.”

…This must be the shape of her “growing feelings.”

“I don’t want you to hate me, Ren-chan… but I can’t stop.”

“I’d never hate you—”

I’m not thinking in terms of love or hate anymore. It’s strange, but I’m beyond that stage. Realizing that felt strange too.

Right now, my mind’s on one thing.

“…How do I make you stop?”

“I… can’t stop myself anymore.”

“…”

Maybe this was my first time feeling my mind go blank. Or second. Doesn’t matter.

The shock was overwhelming.

Even a hard hit to the head wouldn’t compare.

“So, Ren-chan, get me pregnant. Then I’ll probably stop.”

“…”

My spinning mind, with its sluggish core, stayed oddly calm, thinking, “Really?”

“I might throw out all the pills by tonight… what do I do…?”

“…Seriously?”

Her unchanged expression and voice cemented my certainty.

To put it mildly, this is the biggest crisis yet.
