While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 24: When We Spent the Night Together, She Became Strangely Unsettled

Chapter 24: When We Spent the Night Together, She Became Strangely Unsettled

Usotsuki-chan—Yakko Tsukimi.

Her dyed blonde two-side-up hair swayed lightly as she turned back cutely.

“Some day, you’ll fill me up too, right? ♡.”

With a smile so beautiful it sent chills down everyone’s spine, she opened the door.

Usotsuki-chan was about to step out through the front door but paused, putting on an exaggerated show of surprise at the figure standing there.

“Whoa, Yuu-chan!”

“Yuu…?”

“…”

It was Yuu. My classmate, Yuu Onodera, standing right there.

The perfect honor student, excelling at studies, sports, housework—everything.

My childhood friend, next-door neighbor, lifelong connection, and the girl I had a fake relationship with after starting high school…

—No.

The beautiful girl who, today, became my real girlfriend.

She was dressed the same as earlier, from our date—wearing the outfit we picked out together, a brown shoulder bag slung over her shoulder. The only difference was the carry-on suitcase with casters, likely packed for staying over at my place.

…How long had she been standing there?

She seemed to have been waiting at the doorstep, standing still as if on standby—

“…”

Now, in front of my house’s entrance, she stared at Usotsuki-chan, silent and expressionless.

“Sorry, Yuu-chan. I was just borrowing Ren-kun for a bit ☆.”

Usotsuki-chan acted normal.

Smiling brightly, eyes narrowed, looking at Yuu.

“…”

Yuu, on the other hand, was silent and expressionless.

Overwhelmingly silent and expressionless (honestly, radiating intense pressure).

“No need to worry, I’m heading out now. Thanks for the visit, Ren-kun~.”

“Uh, yeah…”

Waving lightly at me, Usotsuki-chan skipped over the stepping stones at the entrance and vanished from sight.

“Yuu?”

Even after Usotsuki-chan was gone, Yuu kept staring in her direction. Something was off about her.

“Hey, Yuu.”

“…”

I held the door open with my body, gesturing for her to come in.

Even with my prompting, she stood there, expressionless, for a while.

Silent, too, so I had no clue what she was thinking.

“Yo.”

“…”

After several calls, her body finally turned toward me, but now she was staring at my face and body.

From top to bottom, bottom to top. Scanning me like she was licking me with her eyes.

What was this unique tension?

Usotsuki-chan’s “nothing happened” act and clean exit should’ve defused things.

It shouldn’t have turned into a battlefield (or whatever this was).

“…Ren-chan.”

“…?”

Yuu dragged her small carry-on suitcase closer, the casters rattling across the ground until they stopped in front of me.

She looked up at me, up close.

Expressionless.

“Come on in.”

I looked away slightly, ushering her into the house.

“…”

Still silent, she stepped inside with me.

“…”

She pushed the suitcase in first, then followed, closing the door behind her with a backhand motion.

And locked it, thorough as ever.

“Ren-chan—!”

“Wha—Mmph!?”

As I turned to her, she leaned into me softly, her gentle body pressing against mine.

Smack.

On tiptoes, Yuu pressed her lips to mine.

A sudden kiss.

“Hey!? Wait—mmph—!”

Smack, smooch, slurp—she kissed me, then licked my lips with her tongue.

With force, she pried open the gap between my lips.

Within seconds of the kiss starting, her tongue invaded my mouth.

This wasn’t quite the passionate side she’d recently started showing… it felt different.

Like she was panicked, or rushed… a desperate kiss, somehow.

Just a feeling.

“Mmh—smooch… ha, mmph—kiss—.”

She kissed me frantically.

I was slow to react at first, but soon our tongues tangled, and we ravaged each other’s mouths, barely pausing to breathe.

Both of us, feeling each other’s breath on our faces, tongues invading, body heat pressing through every inch of contact.

Mid-kiss, Yuu wrapped her arms around the back of my neck.

I slid my hands to her waist, pulling each other closer.

Craving each other.

“—Wait, Yuu. We’re still in the entryway.”

“…Mmh… ♥.”

After savoring each other’s touch, we finally parted, a thin bridge of saliva connecting our lips.

Even after it broke, Yuu’s dazed face, flushed cheeks, and hazy eyes stayed locked on me, her excitement clear.

The scary, blank expression from earlier had softened, almost back to her usual self (?).

“You good now?”

“…!”

At my words, her brows furrowed slightly, a pained look crossing her face. Her eyes glistened, then shifted to my pocket.

She held out her palm, facing up.

“…Ren-chan, give me your phone.”

“Huh? Oh, sure.”

I complied, pulling my phone from my pocket. It was locked, so no worries about her seeing anything easily.

If she wanted to see inside, I’d show her to prove I trust her—

“I’ll unlock it—”

“No need.”

“Oh… here.”

Not sure why, but she seemed to want the phone itself, so I handed it over.

“…!”

Yuu took it like it was something filthy, pinching it between her thumb and index finger.

…As the owner, that stings a bit. Sure, phones aren’t exactly hygienic, but she didn’t have to be that obvious about it in front of me—

“I can’t stand it…!”

With a fierce expression, she said—

No.

With a look of anger, sadness, or barely contained disgust.

She pulled out a pack of portable wet wipes from her pocket, yanking out several sheets roughly.

“Gross… gross… disgusting… disgusting… disgusting, disgusting, disgusting, disgusting, DISGUSTING—.”

Muttering in a creepy, unhinged way, Yuu scrubbed my phone’s screen with the wet wipes, scrub, scrub, SCRUB.

She was wiping it to death.

Stop.

My phone’s gonna die.

“Alright, alright, it’s clean, thank you! But any more and it’s bad for the phone! It might break!”

I don’t distrust my phone’s waterproofing, but Yuu was scrubbing so hard the alcohol-soaked wipes were drenching it.

It was making me super anxious, so I couldn’t help but try to stop her.

“Yuu! Hey, wait, Yuu! I get it! Thanks! It’s clean now!”

“…!?”

My voice snapped her out of it, and her hand froze.

“S-Sorry, Ren-chan…”

“It’s fine…”

I took back my dripping phone from her.

Ugh, it reeks of alcohol!

With no other choice, I wiped it on my sleeve and shirt. It wouldn’t dry completely, but I’d let nature handle the rest.

“I-I…”

“…”

Yuu faltered, looking awkward as she reflected on her actions.

…After all this, I think I get why she was so disgusted and acted like that.

How she pieced together what happened remains a mystery.

“—Ren-chan, call the police now!”

“…Huh?”

Just when she seemed calm, her face changed, and she clung to me, shouting.

“Hurry! Report her! She’s definitely a stalker!!”

“Just to confirm, by ‘her,’ you mean Usotsuki-chan, right?”

“…!”

Yuu nodded firmly, confirming.

Report her… as a stalker?

…Well, I guess it’s reasonable to think that, given how much Yakko seemed to know that she shouldn’t.

But still—

“Hurry…! You have to report her…!”

“Yuu.”

“Oh, right, I’ll report her myself—”

“Yuu, calm down.”

“…?”

She whipped out her phone, already unlocking it, but I placed my hand over hers.

“Why are you stopping me?”

“Think clearly.”

Yuu tilted her head, looking puzzled, clearly not thinking straight.

“Are you really okay with that?”

“—!?”

My question made her freeze, her face stiffening, eyes wide with shock as she stared at me.

“R-Ren-chan…!? What do you… mean by that…!?”

“…”

Shock, maybe fear. Her body trembled slightly, her eyes filled with dread.

“What you just said… what does it mean—?”

“Here, let me take your bag.”

“Huh!? Oh, thanks…”

I half-snatched her carry-on suitcase, surprised by its weight. I braced my right side to lift it. What’s in this thing…?

No way it’s got, like, gym weights, right?

I hoisted the suitcase onto the entryway mat, rolled it a bit, and pulled it into the hallway. Yuu followed, slipping off her shoes.

“C-Coming in…”

“No need to be so formal now.”

“But…”

I gave a wry smile as she cautiously stepped inside, glancing at me nervously.

“Come to think of it, it’s been a while since you stayed over, huh?”

“Yeah… it has…”

She was quiet, almost like a shy cat, her voice trailing off.

“I let you in the house all the time, but this feels weird.”

“Ugh… y-yeah…”

“?”

She looked down, avoiding my gaze.

Even so, her eyes darted around, scanning the house sideways.

Still nervous, huh? Acting all jittery.

“I’ve got a guest room ready, just in case…”

As I said that, guiding her through the house, our feet naturally headed upstairs.

At the top of the stairs, I stopped in front of the room, pausing her suitcase.

Noticing Yuu’s deep breath, I turned to match her timing.

“Yuu, I was thinking of letting you use the empty room next to mine—”

“I want your room.”

“Huh?”

I mean, come on, that’s surprising.

I had two options in mind: the guest room or the empty room next door.

“…Uh, just so you know, the room next door’s mostly used for storage, but it’s clean, not dirty—”

“I want your room.”

“…For real?”

“Dead serious.”

“…”

Straight-faced.

Her big, round eyes stared at me with pure, innocent intensity.

“You’re staying in my room?”

“Is that weird?”

It’s like she was saying, 1+1=2, it’s obvious, don’t you get it?—all with a natural, composed expression, complete with a cute head tilt.

W-Well, considering our relationship just leveled up, maybe it makes sense to do something different, like not sticking her in another room.

…Or am I the weird one? Do couples just start sharing a room the day they confirm their feelings?

No, at the hotel it was for “rest,” not “staying over,” so maybe this is just the natural next step…?

“I mean, we’re dating now, right?”

“That’s how it is.”

“So this is normal, right?”

“Y-Yeah, sure.”

“Staying in my boyfriend’s room is a girlfriend’s privilege, don’t you think?”

“Fair enough…”

Since we’re officially together now, sharing a room doesn’t seem like a big deal.

But she looked so desperate, I can’t help but wonder if she’s up to something. Her pressure is honestly a bit scary.

“Or is there something you don’t want me to see?”

“Nope, not a speck, not a trace, not even a hint.”

“Then it’s fine, right?”

“Go right ahead.”

I straightened up, opened my bedroom door, and ushered her in with exaggerated politeness.

After a beat, she stepped forward.

“…Hehe ♥.”

“…?”

The moment Yuu entered my room, she covered her mouth, letting out a smile she couldn’t hold back.

She must be excited about staying over tonight. Cute.

Watching her back as she hurried into my room, a mix of tension and eagerness, I soaked in the weight of today.

“Staying over…”

Tonight, for the first time in my life, I’d be sharing a room with my girlfriend.

We’d already crossed physical lines, but this—this had its own kind of thrill and excitement.

Experiencing this proof of our evolving relationship brought me joy.

“What’re you doing? ♥ Hurry up ♥.”

“Yeah.”

I dragged her (weirdly heavy) suitcase into my room.

Oddly enough, my room already carried the now-familiar (?) scent of someone else.

It calmed my heart. A strange sense of comfort, like I’d sleep well tonight.

Why, though?

It’s such a weird phenomenon.
