While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 110: This Day (3)

Chapter 110: This Day (3)

“Yuu, you’re gonna be an amazing wife someday.”

“Wha!?!?!?♥♥♥ What’s that out of nowhere!?!?!?♥♥♥ What’s with you today, Ren-chan!?!?!?♥♥♥”

“Well, I mean…”

I regretted saying something so weird.

“Finally ready to get me pregnant?!?!♥♥♥”

“Wait on the pregnancy talk.”

“No waiting!♥♥♥ Today!♥♥♥ Tonight, I’m getting pregnant!♥♥♥”

“I said wait!”

As usual, Yuu’s mind jumped straight to pregnancy before engagement or marriage, and I desperately tried to rein her in.

Her long black hair swayed at the edge of my vision.

The sound of a mechanical pencil scratching on paper echoed.

It’s been a while since lunch, but the kitchen’s aroma lingered in the afternoon living room.

The sky outside the window was gray, hinting at rain.

The weather, and somehow the vibe, didn’t feel like going out.

So, instead of the sofa, Yuu and I sat on thin cushions at the table.

As you’d guess, we were studying.

“Ren-chan, can I ask something?”

“Hm?”

Yuu’s shoulder pressed close, her softness and warmth radiating.

“This part—”

“Let’s see—”

I leaned in, peering at her notebook.

“The last one.”

“Physics, huh?”

“How do I do it?”

“Right, so—”

Physics depends on the topic, but this one had surprisingly few numbers in the problem. It felt like a math puzzle with scant hints or clues. But really, it’s about thinking through the right steps to find the answer. School problems just use learned numbers, units, and formulas.

Yuu’s stuck on a tough problem, barely in the test range, tucked at the end of the textbook like a bonus challenge. So, I reviewed the basics and explained it simply, avoiding spoilers (the answer key).

“—Something like that.”

“Got it!♥”

Yuu answered my small prompts, wrote the equations and solution, then set her pencil down. Turning to me with a bounce, she clapped excitedly.

“Ren-chan, you’re too good at teaching…♥ I totally get it now♥”

“If you understand my teaching, that’s ‘cause you’re smart…”

“Jeez~♥ No need to be so humble~♥”

Yuu leaned into me with a sloppy grin, eager to get flirty.

It’s her usual self, maybe, but… she seems extra clingy today.

“Ren-chan♥ Teach me more…♥ Hand-holding, foot-guiding, waist-grabbing lessons♥”

“Waist-grabbing? What are you, an old man?”

“Then, Sensei!♥ Tame me♥”

“Tame?”

Yuu pressed against me, nearly tackling me.

No way we’re getting it on in the living room, curtains open, before evening.

“It’s not even evening yet…”

“Aw~♥ A little’s fine, right?♥”

“Hey—hold on!”

I caught her as she dove into my chest, tumbling to the floor, playful like cats.

“Ren-chan♥ Ren-chan♥ Ren-chan♥ Ren-chan♥”

Her soft chest pressed through her bra. I’m trying not to let my buddy get too excited.

Straddling me, she lay atop, rubbing against me seductively, wiggling her hips, pressing herself gleefully.

“It’s not even dark yet…”

“But Sensei!♥ Love conquers all!♥”

“Ahem. Yuu-kun, aren’t you getting a bit too wild—”

“Haha!♥ Sensei Ren-chan, that persona’s a bit too old♥”

“Yeah. Feels riskier than the usual teacher-student romance trope…”

A whiff of scandal. So indecent!

“But an older Ren-chan…♥ I’d love to see that~♥”

“Can’t picture it. And stop with the ‘(old man)’ bit.”

Lying atop me, Yuu’s dreamy eyes narrowed, lost in thoughts of the future.

“You’d be a dashing gentleman♥ Super mature, total adult vibe♥”

“Really…?”

“Totally!♥ Absolutely♥ At our kid’s wedding, watching old memories on video, you’d cry more than me♥ Our kid and I would pat you, celebrating their marriage♥”

“That’s way too specific.”

Why’s her imagination so vivid…? Too detailed.

A kid’s wedding? We’re not even married—or decided if we’ll marry.

“Let’s build a happy family someday♥”

“…Yeah.”

“~~~♥♥”

Not wanting to hesitate or deny her, I nodded honestly.

“~~~~~~!!♥♥♥”

Her eyes glistened—

“Chu♥♥♥”

“Mmph.”

She kissed me.

“Yuu, hold on, ‘right now’ is a bit—”

“Nfu~♥♥♥ —Chu♥♥♥”

“Ah.”

“Chu♥♥♥ Chu♥♥♥ Chu♥♥♥”

“Hey, wait, Yuu, what—”

Not just my lips—she tugged my collar, kissing my neck, collarbone, shoulders, cheeks, jaw…

Kissing every inch of exposed skin.

She’d reapplied gloss after lunch, so her kisses left “kiss marks” from makeup, not bruises, all over me.

I can’t see, but I must look wild right now…

Like in anime, manga, or old movies—vivid lip-shaped marks. I could feel them multiplying on my skin.

“Do it to me too♥♥♥ With your lips♥♥♥ My dear husband’s lips♥♥♥ Mark me all over♥♥♥”

“Huh?”

Her boldness threw me.

…Maybe it’s just me, but she didn’t escalate to deep kissing, right?

Something—vaguely—felt off. Even if she’s aroused, she’s not her usual self.

“Hurry♥♥♥ Before I can’t hold back♥♥♥ Kiss my neck♥♥♥ Suck hard♥♥♥”

“Kiss… suck…?”

It took me a second, but I got it.

She wants me to leave kiss marks on her. That’s the play she’s after.

But those “kiss marks”—red spots on the skin—are bruises. Capillary bleeding.

“Hurry♥♥♥ Come on♥♥♥ Suck♥♥♥ My neck’s begging for you♥♥♥”

“…”

Bruises on her neck…

I hesitated to mark her skin like that.

“Hurry♥♥♥ Hurry♥♥♥ Ren-chan♥♥♥ Hurry♥♥♥ Ren-chan♥♥♥”

“…”

Looking at Yuu, I know I’m overthinking it.

But something deep inside me puts the brakes on hurting someone precious—

“If you don’t mark me♥♥♥ I’ll put girl’s lipstick on you♥♥♥ So you can mark me easily♥♥♥”

“Wait, I’ll suck, I’ll do it!”

Her threat blew away my stray thoughts.

A horrifying image flashed in my mind, so I quickly gave in.

Bad. Very bad.

I have no cross-dressing desires. Imagining myself with makeup—I’d puke. Even thinking about it is dangerous.

Phew, close call…

“—Haha♥♥♥ Suck♥♥♥ Lots of sucking♥♥♥”

“…”

Yuu’s sweet, aroused cries were undeniably erotic…

Imagining sucking other parts—must be a curse wired into teenage guys…

“Here I go—”

“Come on♥♥♥”

I leaned toward her neck.

Her scent—gentle soap, maybe perfume.

But she was slightly sweaty, and through her soft dress or directly from her skin, I felt a humid warmth on my cheek.

“—Chu”

“Nn!?♥♥♥”

“Chuu”

“Nnh!♥♥♥”

Sucking her neck, she trembled.

“…”

“Nnh♥♥♥ Nnnh♥♥♥ …Haa♥♥♥ Nnnh♥♥♥”

Half-desperately—

I pursed my lips, sucking her neck to leave the marks she wanted.
