While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 19: If We Crossed That Line, We Couldn’t Stop Until the End

Chapter 19: If We Crossed That Line, We Couldn’t Stop Until the End 

“Wait, Yuu—!!”

“~~~~!! ♥♥♥”

I tried to pull back, but her legs locked tightly around my waist, pulling me toward her with fierce strength.

Creak, creak.

My glans, pressed against her pink mucous membranes, forced its way into her tight, shallow passage—her hymen.

“It hurts—!! ♥♥♥”

Yuu’s face twisted slightly with the pain of her hymen breaking, but—

“Mmph~! ♥♥♥”

With a thud, my penis hit a dead end—the deepest part of her vagina.

“Ohh! ♥♥♥♥”

She let out a guttural cry.

Yuu arched her back dramatically, her body convulsing, trembling so intensely I worried for her.

Her legs, which had been pulling me in relentlessly, went still.

No, they went limp, splayed like a frog’s—exposing her in an almost obscene state—while she let out choked moans.

Her guttural, ecstatic cries continued, as if she were on the verge of passing out from the overwhelming climax.

“Nghh! ♥♥♥ Ohh! ♥♥♥ Mmph! ♥♥♥ Ah! ♥ …Ha… ♥♥♥♥ Ohh! ♥♥♥♥”

“Yuu…!”

My penis couldn’t go any deeper, stopped at what felt like her cervix, the tip kissing it.

I was inside her, as deep as I could go, connected at her core.

Her back arched sharply.

She let out sounds I’d never heard in real life, like the desperate moans of someone on the edge of suffocation.

She was barely holding onto consciousness, enduring an intense, unfamiliar pleasure.

“—Cough, cough, hack… mmph… ♥♥♥”

Her arched back finally collapsed onto the bed.

Her perfectly shaped breasts, shoulders, and stomach rose and fell as she coughed, struggling to steady her breathing.

“Yuu!? Are you okay!?”

No response at first, just coughing, but her breathing gradually stabilized.

Her body kept twitching, beyond her control, squeezing my penis tightly with each spasm.

Painfully tight.

“Yuu, please, please don’t push yourself…”

I pleaded, resting my hand on her soft, melted cheek.

“Mmh… ♥ Sorry, Ren-chan… I might’ve… gone way too hard… ♥♥♥”

“That looked so intense it was bad for my heart…”

I sighed in relief, voicing my honest feelings. She seemed okay.

“So deep… it was… amazing… ♥♥♥ Your thing… went all the way in… I was just so happy… ♥♥♥”

“Yuu…”

Panting heavily, she wiped the sweat from her forehead with the back of her hand.

“Sorry… I might… not have… much left… ♥♥♥”

“It’s okay, don’t push it, Yuu. Let’s rest.”

“But… let me try… a bit more… ♥♥♥”

“Idiot, don’t force yourself! Don’t burn yourself out…”

Yuu, drenched in sweat, gave a weak, sloppy smile, and I got a bit emotional, trying to stop her.

But.

“Yeah… yeah… but! ♥”

“—!?”

Trembling, occasionally convulsing, soaked in sweat, she smiled.

Tears spilled from her eyes, yet—

“I’m okay! ♥♥♥”

Her smile was brave, almost radiant, breathtakingly beautiful.

“But, Yuu—!”

“It’s fine! ♥ It hurts a bit, and it’s a little tough—but it’s finally happening! ♥♥♥”

“—!”

Her legs, splayed loosely, wrapped around my waist again, and her arms, flung out on the bed, reached up to my neck.

Her vagina spasmed, her body shook.

With adoring, narrowed eyes and a melted smile, she pulled me close.

“Finally—finally, I’m connected with my beloved Ren-chan! ♥♥♥♥ I’ve dreamed of this forever… ♥♥♥♥”

“Yuu…”

Tears streaming, trembling, yet beaming with a radiant smile, she left me speechless.

She’d waited for me so bravely, longed for this moment—should I be angry? Should I pull away?

In the end, we’d started having raw sex.

No condoms, no barriers, just skin on skin, mucous membranes joined.

Feeling her trembling hands on my neck, I looked at our connection.

Her fluids soaked the area, but among the frothy arousal, faint red blood stained the base of my penis.

With every slight movement, her slick fluids and blood made wet, lewd sounds—squish, squelch.

“It still… kinda hurts… maybe… ♥”

“—!”

She said it hurt, but she smiled.

“Honestly, it’s… a bit painful if you move… ♥♥♥”

“Sorry, Yuu, I’m trying not to move…!”

“It’s okay! ♥♥♥ Move however you want! ♥♥♥ Don’t worry about me! ♥♥♥”

“I can’t just do that…!”

Each time her spasming vagina and trembling body moved, the stimulation reached my penis inside her.

Her hot, virgin folds, never touched by anything before, teased my penis with their writhing.

Yuu’s vagina clamped down painfully, pulsing as if to push me out.

Then, suddenly, it relaxed for a moment, as if inviting me deeper.

But just as quickly, it tightened again, squeezing my penis painfully, trying to expel me—

“—Ngh! Yuu, sorry, it hurts, please don’t move so much—!”

“No, it’s not—my insides are moving on their own! ♥♥♥♥”

Our connection wasn’t going as either of us planned.

But to say she was already accepting me fully would be too convenient.

My penis was under intense pressure, honestly painful.

Her vagina, unaccustomed to intrusion, was clearly spasming.

“Yuu, stop, if you keep squeezing like that, I’ll really cum…!”

“It’s okay, cum! ♥♥♥ Inside me! ♥♥♥”

“No, that’s why I’m saying stop! Let go of my waist!”

I was steadily, inevitably heading toward climax. She’d briefly loosened her legs, but if she forced me to thrust like before, it’d be dangerous.

Contraception matters. But I’d be lying if I said I wasn’t thrilled to be connected with her.

Raw or not, we were one. United.

I couldn’t help but feel a rush of excitement.

“Ngh—!”

The supreme physical pleasure, the pure elation of being emotionally bound to her.

There was no way I could hold back.

“Let go of my waist! Your insides are spasming! It’s gotta hurt with it so tight!”

“No way! I’m keeping you like this until you cum inside… ♥♥♥”

“Stop—!”

“Hurry, hurry! ♥♥♥ Let it all out, cum inside me! ♥♥♥♥”

“—Ugh!? Ah—!”

“—What!? ♥♥♥♥”

It happened in the midst of our noisy exchange.

I’d sworn I wouldn’t cum inside, wouldn’t finish in her.

I thought I was holding back.

My vision flickered, lights blinking on and off.

The thrill of conquering her deepest place, the intoxication of our hearts connecting, and the guilt of ejaculating despite the risk of pregnancy.

But it all melted into pleasure.

A torrent of overwhelming ecstasy surged through my urethra, pouring into her.

“~~~~~~~!?!?!? ♥♥♥♥♥”

“Ngh—!!”

I released everything I’d been holding back, deep inside her.

“No way…!?”

It happened. I did it.

Spurt, spurt, spurt—into her.

I came. I finished.

Inside Yuu’s vagina. Her deepest place.

Maybe she felt the flow of semen, or maybe my penis’s subtle tremors rubbed her cervix.

“Ohh! ♥♥♥♥♥”

She arched her back like a shrimp, convulsing violently.

Her perfect, bowl-shaped breasts, their cherry tips standing erect, tilted past vertical.

Her jaw and neck were so exposed, it looked painful, her breathing questionable, her body writhing in spasms.

“Ngh! ♥♥♥ —Oh, mm—♥”

She was exhaling without inhaling, barely breathing.

It looked worrying.

“I screwed up…”

I watched her, feeling the blood drain from my face.

I came inside her, at her cervix, her deepest point.

An unbelievable amount of semen.

I finished inside her.

…And yet, why am I still hard?

What’s wrong with me? I thought I was nearly impotent recently, but with Yuu, I turn into a beast?

“Mm! ♥ Ah—ahh! ♥ Ha—mm, mm! ♥♥”

Her arched, bridge-like posture relaxed, returning to lying flat on the bed.

But her face, still twitching, drew my attention.

“Why do you look so happy…? It hurts, doesn’t it…?”

In a blissful daze, her mouth hung open loosely.

Worried she might’ve lost consciousness, I touched her cheek and jaw, checking her pulse.

A bit fast, but calming.

No abnormalities… I think?

Okay, good. Now I need to pull out, scoop out the semen, and clean her—

“Mmphh! ♥♥♥♥”

“—Crap!?”

Pathetically, I was still hard, and pulling out must’ve rubbed her deep inside again, I realized too late.

“Ahh… ♥♥♥”

“Yuu…? Hey…?”

And then, maybe from exhaustion, Yuu—

“Ehehe… ♥♥♥ ♥♥… ♥… Zzz…”

“—!?”

With a blissful smile, she passed out, falling asleep.

“No way, seriously!? I haven’t cleaned out the semen yet!”
