While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 102: Checkmate, However (4)

Chapter 102: Checkmate, However (4)

“Ren-kun, it’s not what you think…!”

“…”

As a result of leaving the bathroom door open, exposing Yuu and my play, Yakko-chan ended up like this. There’s no misunderstanding. It’s undeniable.

“…!!”

Yakko tried to stand but collapsed back onto the floor, her buttocks covering the puddle of her own fluids.

When her rear hit the glistening pool, a faint splash echoed.

“Uh…”

I was at a loss for words in this bizarre situation.

I was shaken too—not as much as Yakko, but still.

What is this situation?

“For now—”

Yuu, still seated on the toilet, leaned against the lid, sleeping soundly (passed out) with happy murmurs—munya, mufu. As I listened, I inexplicably closed the bathroom door behind me.

…Why did I close it?

“—Cleanup! Right, we need to clean up!”

Before my mind went blank, I tried to set a course of action.

“Yakko-chan, where’s a rag?”

“…”

“Yakko-chan?”

“…”

No good.

Yakko stared at the wet floor beneath her, slumped and dazed.

No choice—I fetched a dishcloth from the kitchen.

Wiping Yakko’s love juices—her fluids—off the floor would render the cloth unusable for kitchen duties, but I didn’t know where the rags were, and Yakko was out of it. Couldn’t be helped.

As I moved to wipe the floor, slipping my hands under Yakko’s armpits to shift her—

“Excuse me for a sec—!?”

My vision spun suddenly.

For a moment, I thought it was dizziness or something, but I quickly realized someone caused it.

Instinctively, I braced myself, avoiding a hard fall—but it wasn’t necessary.

Whoever pushed me down didn’t intend harm; the impact was minimal.

“…”

“Yakko-chan…?”

Right in front of my face, as I lay on my back, was Yakko’s face.

No surprise—she’d pushed me down onto the wet floor.

“Ren-kun…”

“What is it?”

Yakko, whose thoughts are hard to read, straddled me—pinned me down. My back felt damp, but wait, calm down—it’s her fluids. Calm down, me.

The dishcloth plan turned into wiping the floor with my shirt—wait, that’s not the issue right now.

Calm down, me.

“You’ve noticed, haven’t you? Yuu-chan’s whim.”

“Hm…?”

I had things to say about wiping her fluids with my shirt, but…

Straddling me, Yakko said something serious with a straight face.

“Whim…?”

“Yeah.”

“…Huh?”

Not getting her point, I tilted my head. Yakko gave a sad smile.

“Really, you turn into such a dunce around Yuu-chan…”

“…?”

“Yuu-chan’s ruthless…”

“…??”

I genuinely didn’t understand what she meant.

“No matter what, even Yuu-chan wouldn’t get that aroused in someone else’s house. Just because it’s you… no, because it’s you, would she have an affair she wouldn’t want interrupted in my house?”

“…”

Listening to Yakko, my mind cooled.

True, I’d felt something off about Yuu’s actions from the start.

If, as Yakko says, Yuu’s outburst was calculated—then it was intentional.

…But if it was intentional, would she go so far as to pass out from sex? It feels more natural that Yuu just lost control, climaxed repeatedly, and passed out from exhaustion.

“Yuu-chan’s passed out for some reason…”

“…”

Yakko, stating her theory, seemed puzzled too. Given Yuu’s state, it’s hard to believe everything was planned.

…So, it’s hard for me to understand why Yakko’s so wary.

“What’s got you so cautious about Yuu?”

I asked, curious.

It felt like Yakko saw something I didn’t.

“This was a checkmate. Or maybe it doubled as one…”

“Checkmate…?”

The dictionary meaning came to mind.

Maneuvering to stop someone—what? Someone behind this? Someone powerful? Are Yuu and Yakko secretly waging a fierce battle?

…Nah, probably not.

My head’s not sharp enough to interpret Yakko’s words in context.

…Damn.

Maybe it’s the fallout from dealing with Yasuoka, but grim thoughts are creeping back.

I should avoid that for my mental health.

“You don’t get it?”

“I don’t.”

“…”

I said it confidently, almost arrogantly, and Yakko looked at me with exasperation.

Oh, ticklish.

Her blonde twin-tails brushed my cheeks and ears, super ticklish.

Also, her face is close.

She doesn’t need to talk that close—I can hear her fine—

“…Dense.”

A bombshell word hit me.

“Huh!? Who’s dense!!”

“Whoa, you got mad… sorry.”

Yakko insulted me with a discriminatory term, so I snapped.

I had to snap.

“Calling someone dense is off-limits. It’s practically a slur. I can’t stand dense guys.”

“Pfft, you of all people say that?”

“I’m not dense, am I?”

“Question mark? That’s weak.”

“I’m not dense.”

“Too late, too late.”

Yakko laughed heartily, looking down at me.

Tears glistened in her eyes.

Was it that funny? I’m not that pathetic.

I hate dense guys who notice others’ intentions too late, get hurt, and play the victim while wallowing.

“…Haha…”

“…”

Yakko laughed, tears in her eyes.

I gave a small smile, never looking away until her laughter faded.

Our faces inches apart.

Her brown irises shimmered, wavering.

Moist eyes, dry lips.

Only up close did I notice her lips trembling.

“Yakko-chan, are you crying?”

“Huh?”

“No, nothing, sorry…”

She’s scary. I was just teasing a bit…

“We’re kinda alike, aren’t we? You and me.”

“How so?”

“When it’s this kind of mood, we joke a bit too much.”

“…”

“…”

“…Maybe.”

“Right?”

We bantered jokingly, sharing wry smiles.

…Honestly, talking calmly with Yakko like this felt refreshing.

The old Yakko might’ve leaned in for a kiss, just to test the waters.

In the past, in a situation like this, she might’ve escalated things to disaster, especially in front of Yuu.

But clearly, her attitude toward me has changed.

Her sharp eyes softened, and seeing her expression made me inexplicably pity her.

Maybe pity’s not quite right, but…

“If you were a dense, pathetic, impotent loser, my heart wouldn’t be squeezing like this…”

“Hey.”

“Hahaha!”

I warned her about going too far, and she laughed again.

Girls shouldn’t say “pathetic impotent loser”—it hurts guys with that issue. World peace starts there. Love and peace.

“Haha… ugh…”

“…”

After joking, her laughter faded, and we stared at each other.

Her eyes, calmer now, regained their usual sharpness.

She seemed ready to continue.

“When I said checkmate earlier, I meant…”

Yakko spoke softly.

“To break the heart of an impertinent interloper.”

“…”

An interloper. Who?

I didn’t have the courage—or foolishness—to ask her directly.

In moments like this, I envy dense guys. They’d get hurt less than someone like me.

“You don’t have to put yourself down like that.”

“…”

I could’ve stayed silent, but instinct told me to speak. That’s what came out.

I had to say something but didn’t know what.

I’ve never been popular with girls—well, except Yuu—so I don’t know what’s right.

“You’re so kind, Ren-kun. Cruelly so.”

“…”

Yakko’s words stung, but her mischievous smile was incomplete.

“Hey… why not break up with Yuu-chan and go out with me?”

“What a thing to say.”

A terrible joke.

“I’d… do things right.”

Hiding her hurt behind her hands.

“I wouldn’t get horny in public, and I’d prepare condoms properly.”

Wearing a playful expression.

“I’d do things Yuu-chan would never do.”

“…”

Too direct to be seduction.

Too desperate, almost painful.

“So… how about it?”

Her pleading demeanor, her resolute expression, stirred something in me. It thrashed.

“Yakko-chan, you know how intense Yuu’s possessiveness is.”

“Yeah…”

I know it’s a cowardly thing to say.

Using her as a shield is the worst.

But it’s the most efficient.

The least hurtful for Yakko, I thought.

“Just being this close, touching like this, is enough to set her off.”

“…”

I watched Yakko, gauging the effect.

Aiming to make her give up cleanly without hurting her.

“I don’t want to hurt Yuu. She’s loved someone like me all this time, and I want to make her happy. I can’t imagine being with anyone else.”

“…”

Yakko fell silent. Usually, this is when she’d be swayed—during fights with Yuu or talks with me.

—But.

What was I thinking?

Why did I assume she’d give up?

She was changing.

Like Yuu once did, Yakko Tsukimi was transforming before my eyes.

And I completely failed to predict her next move.

“What are your feelings, Ren-kun?”

“Huh?”

“How do you feel about me?”

“Fweh… uh…”

Pathetic sounds, I know.

I tried to dodge but couldn’t think of words fast enough.

“You’re so kind, you prioritize Yuu-chan’s feelings. I get that. It’s so you. But—”

Still straddling me, Yakko shifted suddenly.

Lying flat on me, she squirmed.

Wriggle, wriggle. Rustle.

Her crotch moved closer to mine—Pattern Blue, it’s an Angel! Danger!

I had to escape this crisis. Fast.

Before our crotches aligned. Before my Lance of Longinus pried open her Gaf’s Chamber.

“Hey, wait, Yakko-chan—!”

“If you push me off, I’ll spill everything.”

“—!!”

“…So, your feelings?”

“…!!”

…Yup.

The feared scenario arrived.

Trapped, with physical—punishment.

“Ren-kun, you’re super hard.”

“I’m not.”

“You totally are.”

“…”

I shut up.

I had no choice.

“…Ugh… wow… it’s got such presence between my legs…”

“…”

Don’t say “wow” like that—it’s a bad interjection for both genders—but she wasn’t wrong.

“Don’t tell Yuu.”

A pitiful voice escaped my throat.

Huh? My throat’s trembling. Weird.

“It’s just physiological, right? I mean, my body does turn you on… it can…”

“…”

Her words betrayed low self-esteem, but I couldn’t comfort her.

…Because I was hard.

My penis, trapped between Yakko’s smooth thighs as she lay on me, proclaimed, “I have no regrets in my life!!”

“I thought so… does this mean… you like me too!?”

“You just said it’s physiological.”

“…”

“Don’t rub! Don’t grind with your thighs!”

Terrifyingly, Yakko moved her hips, wiggle, wiggle, with my penis between her thighs.

Honestly, it wasn’t “grind” but slippery. Her wet vaginal area felt unexpectedly good. No pubic hair, no scratchy sounds—just slippery.

The sensation of my penis sliding along her slit felt like sumata (it was sumata), the teasing pleasure heightening my arousal.

“Hey, stop! Really! To Yuu, this is definitely cheating! Bad! To her, this crosses the line! Let’s stop, for both our sakes!!”

“Yuu-chan doesn’t matter. I’m asking about your feelings.”

“—!!”

“It’s not cheating. It’s an interrogation.”

“What kind of interrogation…!”

Our genitals were technically touching… but not cheating, an interrogation?

…Am I being tested?

Oh, God, save this pitiful lamb…

“Ugh, I want your real feelings, Ren-kun. Loud and clear.”

“…!”

Fine, whatever. Let it be.

“Yakko-chan! You’re fun to be with, a great friend!!”

“Uh-huh, and?”

“A comfortable friend!!”

“That’s the same thing.”

“Gahhh! Don’t squeeze with your legs! Don’t clamp down!”

“I haven’t put it in my pussy yet, have I? You’ve already… done stuff with Yuu-chan… If you cum from this, you wouldn’t be able to face her, right?”

“Ughhh, kuhhh! Stop—ow, that’s a bit painful…”

“Oh, sorry… harder to control than I thought. Is a dick that sensitive?”

“Of course it is.”

Yakko eased her tight thigh grip.

Phew… thought I’d die (socially).

“Phew…”

“Hmm…”

“…What?”

“Nothing~☆”

“…?”

Yakko, still lying on me, seemed pensive.

When I asked why, she dodged with a cheerful grin.

“I see, I see~☆ Fun to be with, huh~☆ Comfortable, huh~☆”

“…As a friend, okay? A friend…”

“Pfft☆ Ren-kun, you treat me so casually usually, but deep down, you see me as a girl, don’t you☆”

“…”

What’s with her? She’s ecstatic.

…Why’s she so smug?

“Just get off m—”

“Get off,” I was about to say, thinking we’d laugh it off, but I let my guard down.

“—Cuz☆ Poor Yuu-chan~♪ Her beloved boyfriend’s charmed by me too♡”

“…Huh?”

“…”

…What just happened?

The bathroom door was open.

And there—

“Get off Ren-chan.”

She was there.

My girlfriend, Yuu Onodera.

A naked, long-haired beauty, dripping a mix of semen and fluids onto the floor, staring down at us with pitch-black, abyssal eyes.

“Get off Ren-chan—”

“Eh~☆ But Ren-kun’s so har—Kyaa!?”

“I’m so sorry!!!”

Without hesitation, I apologized.

Flipping Yakko off me, freeing myself, I dropped to the floor.

On my knees and hands, head bowed—dogeza—I offered heartfelt apologies.

“I’m so sorry!!!”

Momentum.

There’s no posture lower than dogeza. Anything more would be atoning with my life. This was the ultimate apology.

Like a dog showing its belly, I threw everything into apologizing.

“I said, get off Ren-chan.”

“Eh~☆ Won’t Ren-kun’s thing need to cum once to calm down~♡”

“It’ll go down with time. You wouldn’t know, with only doujinshi knowledge.”

“Oh… really?”

“Yes…”

“Why so formal?”

“I’m dying of guilt…”

“Haha☆ No worries, this time, actually—”

“Don’t look up yet, Ren-chan.”

“Yes! I’ll stay in dogeza forever! I’ll live flat on the ground for life!”

“I don’t want you seeing Tsuki-chan’s body for even a second.”

“Yes! I won’t look at Yakko-san’s body, no way, not at all!”

“Hey, Ren-kun, you got hard over my body, and now you say that?”

“Tsuki-chan, put some clothes on.”

“Okay~”
