While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 27: When We Spent the Night Together, She Became Strangely Unsettled (3)

Chapter 27: When We Spent the Night Together, She Became Strangely Unsettled (3)

In my room, after flirting with Yuu and calming our libidos a bit, she started pacing around restlessly. 

Her white flare skirt swished, her long, glossy black hair swayed, and she wandered back and forth, back and forth. Her movements were so suspicious that I asked with a wry smile:

“What’re you doing?”

“Hmm… just got curious.”

“Curious…?”

She was glancing under the bed and at the books on my shelf. She positioned herself to block my view, hiding her hands as she moved, so I couldn’t tell exactly what she was up to. Just pacing, rustling, pacing, rustling. Stopping here and there, it looked like she was rummaging through everything.

Not that she was making a mess. The stuff she touched was left so neatly it was almost weird, like nothing happened. Was she searching for something?

“Wondering if you’re hiding any naughty magazines~.”

“Oh? Think you’ll find any?”

“Yeah, right~.”

Apparently looking for porn, she dodged my challenge with ease, spinning away from the bookshelf with a flourish. Satisfied after scouring the place, she ended her hunt for dirty relics, flashing me a grin as she spoke.

“Your naughty stuff’s all digital, right? ♥.”

“…That’s not what I meant.”

I froze inside, secretly rattled. I tried to keep a straight face, but my eyes flicked away, and she caught it, smirking wickedly.

Hands behind her back, she stopped in front of my desk. On it, a monitor and keyboard sat at the back, with space up front for miscellaneous stuff. Next to it was my black PC tower, silent since it was off. A totally normal setup. Yuu’s been to my room tons of times—she should be used to it by now.

…But for some reason, she turned to the PC tower and just stared.

Ten seconds passed, and she still hadn’t moved.

I got a bad feeling.

“Your PC’s probably full of sister fetish videos and childhood friend porn history, huh~.”

She muttered it casually, like it was nothing, but it was a bombshell.

“N-No, I don’t watch or read that stuff, I don’t know what you’re talking about.”

“Yeah, sure~ ♥.”

How does she know?

…No, wait, “sister fetish” is a taboo word for anyone with a real sister. Real life and fiction are totally separate. I keep it that way when I enjoy—uh, never mind.

More importantly, how’s the actual childhood friend herself casually bringing up childhood friend porn?

What’s she feeling when she says that?

“…Hey, Ren-chan.”

“What?”

Yuu called out to me, still facing away.

Motionless, her expression hidden, I couldn’t read her mood.

“Can I delete all your porn?”

“What a thing to say.”

Her unexpected line drew a defensive response from me.

“But you’ve got me ♥.”

“I get what you’re saying, but… uh…”

Today, the very day we crossed that line.

My outlet for sexual urges was about to get shut down.

Honestly, I don’t want porn to count as cheating.

…Not to make excuses, but sometimes stuff builds up physically, and letting it out is necessary for mental and physical health.

Feeling like I was speaking for all guys, I calmly pushed back.

“Then just cum with me, okay?”

“…”

Yuu turned to face me, dead serious.

My pushback went nowhere.

…Man, Yuu’s dropping bold lines again.

At this point, a tiny bit of despair crept in, like, “This isn’t getting through.”

Her face was that serious, her tone that flat, like she was just stating facts.

“Do you want to cum with other girls, Ren-chan?”

“That’s not it, it’s just…”

No, wait.

Isn’t that like using her as a sex toy?

Treating my precious girlfriend like a tool for getting off?

I don’t want that… So I tried some half-baked excuses.

“I don’t mind if you do.”

“You don’t…?”

“Yeah. I’m fine being your sex toy. Because, you know, thinking about the person you love getting off to someone else? That’s kinda gross, right?”

“Uh, yeah…?”

I’d never thought about it. Is she saying I should put myself in her shoes?

“So, if I got wet thinking about some guy you don’t know, how would you feel, Ren-chan?”

“…”

I’d never considered it. But now that she mentions it, she’s got a point… maybe?

“Right? That’s what I mean.”

Reading something in my expression, Yuu smiled smugly.

“Ren-chan…”

Her face shifted to a worried look, her voice soft and pleading.

“Are you… not satisfied with me?”

“Not at all.”

“—! ♥ T-That’s right, huh? ♥♥.”

She asked, but when I answered straight-up, she got super embarrassed.

Honestly, I have zero complaints about her. Setting aside future what-ifs, my dick reacts to her like crazy right now.

I thought I had ED issues until recently, but it’s a miracle. A real miracle.

How could I be dissatisfied with the girl who sparked this miracle, the savior of my son?

“I’ve got no complaints about you, Yuu.”

“T-Then it’s fine, right? ♥♥♥.”

“Yeah, well…”

I’m not just losing—I’m already defeated. It’s like the battle was over before it started.

This feeling, it only happens with Yuu.

“But if you’re out of material, that’d be tough for you, right, Ren-chan? ♥ So, how about I send you a sexy selfie every day? ♥.”

“Uh, that’s generous and tempting, but… can I think about it?”

“Aww ♥ No need to hold back~ ♥.”

“Haha…”

So sexy.

But, uh.

The idea of my phone getting flooded with her naughty pics… I still don’t know how to feel about that, so I put it on hold.

“Just say the word ♥. I’ll do sexy stuff for you anytime, anywhere ♥.”

“Thanks, Yuu, that’s enough, no more horny talk.”

“…♥♥♥.”

Her breathing sounded a bit heavy again, so I called it quits. I tried so hard to play it cool earlier, saying we’d keep it chill tonight, but this is ruining my vibe.

Trying to calm down, I glanced away and caught sight of the wall clock.

“—Oh.”

The analog clock’s hands showed it was already past 7:30.

“Dinner?”

“Yeah.”

Yuu, picking up on my glance, suggested it like she read my mind.

“You rest, Ren-chan. I’ll make dinner.”

“I need to clean the bathroom… so, can I leave dinner to you?”

“Okay! ♥.”

We left my room, each heading off to our tasks

*

After finishing the bathroom cleaning and prep, Yuu told me to take it easy. 

I offered to help with dinner, but she’d claimed the kitchen, stubbornly maintaining her dictatorship, so I let her take charge and plopped down on the living room sofa.

“~♪”

I could hear her humming a trendy song I recognized.

Right now, she was cooking in the kitchen, wearing an apron over the same outfit she wore on our date—despite the risk of getting it dirty. Watching her work so skillfully and cheerfully, I couldn’t help but think, She’d make a great wife. The thought was so embarrassing I quickly shook it off.

Grrrowl~

Staring at her absentmindedly, the delicious aroma wafting over stirred my stomach.

“Hehe ♥ Just a little longer, okay~? ♥”

It wasn’t that loud, but she heard it, cooing at me like I was a kid.

Man, is dinner ready yet? What’s she making?

I caught a glimpse of her prepping fish and shellfish, and the smell that followed confirmed one dish was definitely acquapazza. That’s a fish-based soup dish, cooked with veggies and herbs, known for its gentle flavor and rich aroma. Olive oil and tomato versions are famous, but the ingredients and spices can vary endlessly, so maybe there’s a “family recipe” vibe to it.

Tonight’s table would feature acquapazza, but assuming the whole menu’s Italian would be jumping the gun.

Yuu’s cooking skills are practically pro-level. She tweaks existing dishes like it’s nothing and whips up original creations like she’s breathing. That acquapazza? It might turn out to be some fish dish that’s almost acquapazza but totally her own.

The smells—consommé, garlic, olive, even a sweet soy-based scent—were so chaotic I couldn’t pin down the menu. But with Yuu in charge, it’d be delicious no matter what, so I stopped guessing and just waited. She’d mentioned using stuff from the fridge and freezer, so I let her go wild. I haven’t seen my sister in a while, but Yuu’s cooking gets plates licked cleaner than mine, so her food’s special—especially for the Hoshimiya family.

Oh, Yuu’s digging through the freezer. She pulled out—a seafood mix. A value pack of ocean goodies.

Squid, shrimp, scallops, the works—stuff I forgot I even bought.

I’m so over seafood, but if Yuu’s cooking it, I can probably eat it without gagging.

Opening a kitchen cabinet, Yuu gasped, “Whoa, way too many instant noodles…”

She was floored by our stockpile of junk.

I regretted buying them too. My tongue—no, my stomach and esophagus—can’t handle that seafood-flavored instant ramen anymore. Just putting it in my mouth makes me wanna puke.

Instant noodles, yakisoba, and the like have surprisingly short shelf lives—about six months from production, I heard. Stuff expires before you know it, more often than you’d think. Weird.

I stock up when I’m busy or too lazy to cook, but they’re mostly carbs, salt, and fat, so they lose out to supermarket or convenience store deli food. Instant noodles are only good for convenience (quick meals) and cost (cheap and calorie-heavy). If the local supermarket has cheap, hearty deli options, I skip the noodles.

Additives aren’t great for teenage skin either, so I’ve sworn off giving this stuff to my sister. There was a time when instant noodles were a lifesaver during busy periods, but that irregular lifestyle and additive-heavy diet gave me acne later. When a single pimple popped up on my forehead, Yuu freaked out. I’m not prone to acne, so I did a full health check then.

It really hit me—sleep and food are crucial.

The longer time passes, the more I appreciate my childhood friend.

“Hey, Ren-chan! Is this enough for your sister?”

“Whoa… already done? That was fast.”

By the time I answered, Yuu was gone from the kitchen.

On the counter, dinner was already plated.

Then I heard thump, thump, thump—Yuu coming downstairs. She’d brought a tray of food to my sister’s room.

“Sorry about that. Thanks.”

“No prob! It’s a wife’s duty ♪.”

“Wife, huh?”

Jumping the gun, but it’s cute.

“Alright, here we go! Sorry for the wait~ ♥.”

“Oh, hell yeah… Been waiting!”

Yuu set the dinner spread on the living room table.

“Whoa… this is insane. You went all out…”

“Ehehe ♥ I tried a little harder than usual ♥.”

Looking at the dishes, my eyes were practically sparkling. Or maybe the food was.

“Seriously… this is… unreal. I’m speechless…”

“Aww, don’t flatter me like that~ ♥.”

“Can I eat?”

“Go ahead ♥.”

“Thanks for the food!”

“You’re welcome~ ♥.”

I couldn’t wait, blurting out “Itadakimasu” before Yuu even sat down, barely clasping my hands.

The main dish was acquapazza, as expected, but that’s where my predictions ended. She used cod, keeping it light, and served it with a deep dish of scallop ajillo on the side. You could add ajillo ingredients to the acquapazza to adjust the saltiness. It felt Italian but with a customizable twist, almost British in vibe.

The taste? Phenomenal. Adding the ajillo’s saltiness to the acquapazza, the seafood aroma filled my nose, and each bite released gentle veggie umami and deep seafood flavor, bursting in my mouth. The ajillo’s smoky garlic mingled with the acquapazza’s subtle herb-spice scent, creating a magical reaction. Delicious and addictive.

It’s a level of perfection I’d never reach cooking myself.

The main carb was a taco rice made with mixed grains (taco-grain rice?). Lettuce, tomatoes, carrots, ground chicken, cheese, and a salsa sauce with a faint soy scent blended into a light yet spicy flavor.

And as a bonus, a pot-au-feu with veggies cooked to a melt-in-your-mouth texture.

The spread was colorful, visually fun, gentle on the stomach, and good for the body. Lately, I haven’t paid much attention to my diet, so this hearty, veggie-packed menu was a godsend.

It’s perfect.

“How’s it taste? ♥”

“Too perfect.”

“Really? ♥ Yay ♥.”

There’s no way her cooking wouldn’t be amazing.

But one thing caught my eye.

Tucked among the dishes was a small container of amber liquid.

Thick, with a sweet aroma… honey, definitely.

Looking around, there was no honey on Yuu’s side—just mine. A tiny cup, like one for mouthwash, filled to the brim with it. What’s it for? Dessert, maybe? It stood out, totally different from the other dishes.

Was it meant to be paired with something, like a “mix it in” deal? Pancakes would make sense, but there were no sweets to drizzle it on. Not for the acquapazza, ajillo, pot-au-feu, or taco rice… So what’s the deal with this honey?

“Yuu, what do I put this honey on?”

“…♥”

Yuu, grinning ear to ear, kept her smile fixed and said:

“Drink it ♥.”

“Huh…? Drink… it?”

She meant drink the honey straight, right?

“It’s delicious~ ♥.”

“…Got it.”

Seems like that’s the plan.

Under her beaming gaze, I tipped the honey down my throat.

“…Ngh… Hm?”

I braced for a sickly sweet burn, but it went down surprisingly smooth. It had the texture of honey but tasted like a slightly rich soft drink made with it. High sugar, but not too high. Maybe Yuu tweaked it to make it easier to drink.

“Tasty? ♥”

“Yeah, it was good.”

“Yay… ♥♥♥.”

“…?”

Yuu lit up with a weirdly thrilled smile before digging back into her food.

What was that honey about?

Was there some special meaning to drinking it during the meal?

A thought hit me, and I asked:

“Was it, like, a substitute for an aperitif?”

If so, maybe I should’ve downed it before eating.

Since Yuu curated this meal, her intention’s probably the right call.

But—

“Nope? Doesn’t matter if it’s before, during, or after. As long as you drink it, it’s all good ♥.”

“Really…?”

“It’s like a… spell to boost your appetite or something. If it was tasty, that’s enough. Don’t worry about it ♥.”

“Alright, cool.”

I don’t fully get it, but gulping down honey straight isn’t an everyday thing. Yuu’s relentless grin is a bit concerning, but the food’s amazing, so I’ll let it slide.

“By the way, Ren-chan, do you prefer meat or fish in the morning?”

“Either’s fine.”

“You’re the type who can handle a big breakfast, right?”

“Pretty much.”

“If you had to pick, is there something you’d want every morning?”

“Well, obviously—”

“Not rice. I know you’re a rice guy. I mean the side dishes.”

“Hmm, nothing specific. Why?”

“You said a while back you liked meat for breakfast. Just wondering if that’s changed.”

“You remember that…?”

“It’s about you, Ren-chan! ♥.”

“R-Right, makes sense…”

I told her I still love meat, and she nodded, eyes lowered, murmuring, “Hmm…”

“…I wanna make breakfast for you every morning.”

“Huh?”

I met her gaze, and her face was bright red, embarrassed by her own words. She wouldn’t even look at me.

“T-That’d be great, but… that’s too much, Yuu.”

“Why?”

She looked at me, surprised. To me, turning her down was obvious, but she probably wants me to lean on her more.

“It’s too much to ask. You’re already making me bentos on weekdays.”

“Bentos are just a side thing when I make breakfast! I’ll be your live-in wife~ ♥.”

“Live-in wife…”

That phrase alone is rare these days.

“What about your family’s meals? Lately, you’ve been making breakfast for your mom and dad, right?”

“I’ll make Mom take over breakfast duty again!”

“No way.”

Yuu puffed out her cheeks, pouting. It’s a sweet offer, and her reaction’s so adorable I couldn’t help but smile.

I appreciate it, but her parents rely on her for chores. I can’t mess with that.

“I’ll take the thought. Thanks, Yuu. I love how kind you are.”

“~~~!?!? ♥♥♥ O-Okay… I’ll let it slide for now… ♥.”

“Do that.”

“…♥♥♥.”

“…?”

Her breathing got heavy again. She was giving me a slightly dangerous look.

“Yuu? You okay?”

Her eyes glinted with something—I don’t know what, but it was intense.

“S-e-c-r-e-t… Was it tasty? ♥.”

“Huh? …Oh, the honey? Yeah, it was good.”

I already said that, didn’t I? What’s up with her?

“What’s that about?”

“N-Nothing~ ♥♥♥.”

Whatever. The food she made is too good to not focus on—it’d be rude not to savor it.

And so, our cozy dinner time passed in that warm, easy vibe.
