While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 25: When We Spent the Night Together, She Became Strangely Unsettled (2)

Chapter 25: When We Spent the Night Together, She Became Strangely Unsettled (2)

Today, I got a girlfriend.

Yuu Onodera, who’d been my fake girlfriend, accepted my confession, officially becoming my real girlfriend today.

We went on a date, had sex, came home to her mom’s blessing, and now we’re starting a sleepover date in my room—

“Ren-chan’s bed! ♥”

—And now, my girlfriend, Yuu, just dove onto my bed.

“Sniiiiff ♥.”

“Hey.”

“Haaaah ♥.”

“Stop it.”

Her long, glossy black hair splayed out as she buried her face in my pillow, taking deep breaths.

Giving the pillow’s owner maximum embarrassment, she hugged it tightly, rolling around on the bed. The more I told her to stop, the happier she seemed, nuzzling deeper.

“Stop sniffing my pillow.”

“Whaaat? ♥”

“Come on, let go.”

“No way! ♥”

She wouldn’t let go, stubbornly resisting as I tried to pry it away.

Her defiance reminded me of the old, bratty Yuu, making me smile despite myself.

Sitting on the bed, I bantered playfully with her adorable antics.

I subtly smoothed her skirt to keep it from wrinkling.

Since she wasn’t wearing her usual hair clip, her hair spread out on the bed, so I gathered it for her.

“You love my hair, don’t you, Ren-chan? ♥”

“Yeah, it feels amazing.”

“I take good care of it—mm! ♥”

“That reaction’s too sexy.”

“It tickles! ♥”

“Hold still, it’ll get tangled.”

“Ahh—♥ Your touch is too much, Ren-chan! You perv! ♥”

“It’s normal, normal.”

Alone in my room, we could flirt without limits.

Teasing about being sexy or not, or reminiscing about old times, letting memories bloom.

A sweet, warm, lazy time flowed by.

Exactly the kind of “home date” I’d pictured with a lover—my ideal scene come to life.

“Ren-chan ♥.”

“What?”

“Just wanted to say it ♥.”

“You little—”

“Mm! ♥ Nooo ♥.”

I flicked the hair at her nape as she said something cheeky, making her squirm.

“Sniiiiff ♥ Haaaah ♥.”

“Don’t sniff, let go of the pillow.”

“…♥.”

Yuu still wouldn’t release my pillow, hugging it tighter the more I protested, hiding half her face behind it while beaming at me.

So cute.

What am I supposed to do with this creature?

She’s sexy, adorable, my girlfriend—I honestly want to pounce on her right now.

“Hm?”

“…♥♥.”

She reached out, grabbing my sleeve tightly.

“…♥♥♥.”

Silent, still hiding half her face, her alluring eyes locked on me.

Tug, tug, pulling my arm.

No sign of the lustful frenzy from after the hotel.

…No.

Yuu, lying on the bed, was rubbing her thighs together, and I was deliberately ignoring it.

In reality, she was probably already—

“My pussy’s all wet with cum and juices right now ♥.”

“…Hey now.”

Always so damn sexy… no, that’s not it.

We just shared our first time today. Even at the hotel, she kept fussing over her crotch.

From the start, we wanted each other too much. Despite the strain on her body, I let her lead and went wild myself.

Releasing a ton of cum inside her, flooding her vagina for the first time—thinking back, it feels downright brutal.

“It’s already wet, so a little more won’t hurt ♥.”

“No way. Like I keep saying, take care of your body. I don’t want to push you too far.”

“But it’s our special day, right? A little pain’s fine. I hear the first time’s supposed to hurt anyway.”

She even said she was ready for the pain.

That’s exactly why I want to treat her gently.

“Besides, you were pent up too, right, Ren-chan? ♥ You came so much ♥.”

“—!”

“Wanna cum inside? ♥ Fill my pussy up, squirt squirt~ ♥ Come on, Ren-chan, cum inside me more ♥.”

“—!?”

She pointed at her chest and crotch, guiding my gaze.

Her heavy breathing, that sweet, melted voice.

Her seductive act—part calculated, part natural—hit every button, stoking my desire with terrifying precision.

Trying to melt my reason, break it.

In short, she’s sexy. Too damn sexy.

And right now, her own reason’s a bit broken.

…But as much as her eagerness pulls at me, I can’t let myself get swept away.

“It’s because it’s a special day. That one time should stay special, don’t you think?”

“Mmm…”

Maybe because she could relate, Yuu pouted, looking a bit hesitant, then tugged my sleeve again.

“I just wanna do it ♥. Please, Ren-chan ♥. My pussy’s already leaking, soaking my panties… ♥.”

“—!!”

With that, Yuu slid her middle finger over her white flare skirt, pressing into her crotch.

Through the fabric, the fertile triangle was outlined, her slender finger marking the sacred slit. I couldn’t help but want to pray to it—no, stop, I’m joking to distract myself, but it’s not working.

It’s all because Yuu… she’s too damn sexy!

I’m getting hard!!

“Please, Yuu.”

My head was already spinning, but I desperately tried to rally, redirecting the blood rushing to my crotch.

Alright, gather up! No going to my dick! Don’t break formation!

…But sadly, there’s always a rebel. Some blood reached my crotch, getting my penis half-hard in a sweet, defiant erection.

My son’s in full rebellion mode.

“—♥♥.”

Somehow sensing the change—or maybe just the vibe—Yuu stared at my crotch like she could see through my pants.

Hiding it with my hand might’ve backfired.

“Ren-chan, that’s… ♥♥.”

“No. Nope, not happening.”

“Come on~ ♥ Just the tip, just the tip ♥. Please? ♥.”

That’s a fuckboy’s line, promising and breaking…

“Just rub inside me a bit and squirt, that’s all ♥. That’s enough to get me pregnant ♥♥♥.”

“Pregnant!? You’re on birth control, right!?”

“I am, but~… ♥.”

Yuu rubbed her thighs together under her skirt.

“But if it’s your cum, I feel like I’d get pregnant right away ♥♥♥.”

“You can’t get pregnant…”

Somewhere along the line, sex turned into pregnancy talk.

I’m sure she’s joking, but it’s terrifyingly intense.

“Did you know? If you miss even one low-dose pill, the contraception rate drops to like 90% ♥.”

“R-Really…?”

Even then, 90% is pretty high, but I’d never say that—it’s too risky.

To put it in relatable terms, think of a gacha game, though it’s crude.

A few milliliters of sperm in her vagina gives a 10% chance of a baby.

That’s insanely high. You’d be shocked if you didn’t pull it. And the devs can’t rig the odds.

A little imagination makes the danger clear.

What a terrifying gacha.

And that 90% figure assumes you’re taking the pill regularly and haven’t missed a dose recently.

If you’re not on the pill, not using condoms, and not taking the morning-after pill—well, it’d be a miracle not to get pregnant from cumming inside.

“Maybe I’ll ‘forget’ to take my pill tomorrow~ ♥.”

“Absolutely do not forget.”

Even with a pill that’s almost foolproof, it requires consistent effort—taking it at the same time every day. The morning-after pill has side effects you can’t ignore, and for Yuu’s health and future, sticking to the pill or using condoms is the way to go.

Rules we follow because we care about each other.

It’s important.

By the way, even with the pill, there’s a tiny fraction of a percent chance of pregnancy.

“Mmm~ ♥.”

Yuu grinned, cheeks puffed up with satisfaction.

“What’s up?”

“You’re thinking about me so much ♥. You really cherish me~ ♥.”

“Well, duh…”

“Mmfufufu~ ♥♥♥.”

She looked thrilled. That’s great, but… please, really, stick to birth control.

I’m begging you. I’ll do my part too.

“I’ll make sure to use condoms next time—”

“No way, absolutely not.”

“Huh?”

My arm, already gripped tightly, got yanked hard.

Propping my elbow near her shoulder as she lay on the bed, I found myself staring into her face up close.

A beautiful girl gazing back, but now there was an intense edge to her.

Pillow set aside, she was dead serious.

“Please. Can we go raw for at least the first week?”

“But—”

“Please.”

“…”

Not a sweet or pleading tone—her voice was flat, serious.

“Eight years, you know? I waited eight years.”

“Eight years…”

Her words stunned me.

That timeframe… it could only mean—

“To be exact, seven years and three hundred fifty-one days.”

“Oh… huh?”

“Since then, it’s been that long.”

“Right…”

Then—when Yuu was being bullied.

To keep track of the exact days like that… she must’ve cherished every single one.

“Please, Ren-chan. I can’t hold back anymore. It’s too much, too painful—”

“Yuu…?”

“I might just forget to take my pill tomorrow.”

“Don’t you dare forget. I’m begging you.”

Stop trying to “forget” your pill every chance you get.

…Wait, what’s this about “trying to forget”? You don’t call deliberate inaction “forgetting,” right?

She’s joking… right?

Her deadpan delivery makes it hard to tell if she’s serious or not.

“…Alright. Fine, we’ll go raw for a bit…”

“Yay! ♥.”

Yuu’s face lit up like a blooming flower.

…Normally, isn’t it the guy begging, “Please, let me go raw!”?

It’s flattering that she craves such intense closeness, but it makes me a bit worried for the future.

In terms of rational brakes, I mean. It’s just the two of us to keep things in check.

If one of us gets swept up in passion and drags the other down with them, that’s a problem.

Did I just make a mistake agreeing to raw sex? Will I regret this choice later? The unease is already creeping in.

“Then, let’s get started… ♥.”

“Wait.”

I stopped Yuu as she reached for her clothes.

“Why?”

“Let’s hold off for today.”

“Come on~ ♥ Let’s do it~ ♥.”

Her expression melted, eyes glossy, long black hair splayed on the bed as she gazed up at me. Her perfectly shaped, ideal-sized breasts caught my eye.

I noticed her fingers unconsciously stroking her crotch at the edge of my vision.

Her provocative pose was driving me wild, but I couldn’t let myself lose control today.

“I’m already ready~ ♥.”

“…Like I said, let’s hold off, okay?”

“Aww~ ♥ You don’t have to worry~ ♥.”

“There’s still some discomfort down there, right?”

“Well, yeah, but~ ♥…”

Maybe not outright pain, but right after losing her virginity? Pushing her body without checking its condition is a bad idea.

It might be selfish of me, but I wanted to give her at least one night to recover.

“Please, Yuu.”

To show I wouldn’t budge, I looked straight into her eyes.

“Let me cherish you properly.”

“~~~!?!?!?!? ♥♥♥♥.”

Yuu covered her face with both hands, trembling.

Her expression was a mix of a smile and distress, impossible to pin down.

But her body was shaking.

“You good with that, Yuu?”

“~~~♥♥♥.”

She didn’t answer for a while.

“Yuu?”

Then—

“~~~Haa! ♥.”

She dropped her hands, letting out a big breath.

“My heart almost stopped! ♥♥♥.”

“…”

She looked overjoyed.

“My boyfriend’s too cool! ♥♥♥ He cherishes his girlfriend so much! ♥♥♥.”

…Well, that’s that. She seemed to agree, at least.

“Then tomorrow, okay? ♥ Tomorrow! ♥ It won’t get me pregnant, so it’s fine, right? ♥♥♥ We’ll do it all day tomorrow ♥♥♥. I want you to cum inside me tons ♥♥♥.”

“All day might be a stretch, but yeah, tomorrow’s sex should be better than today’s.”

“It’s a promise! ♥♥♥.”

And just like that, our Sunday sex plans were suddenly set.
