Chapter 64: The Key to Escape

My lower half, already defiled by Yuu, remained in the same shorts as she climbed onto my lap.

Still seated on the reclining bed, leaning against the backrest, her thighs straddled mine, our lower abdomens pressed together in a face-to-face position.

“Ren-chan…♥♥♥”

Her melted, dreamy gaze and loose smile fixed on me.

She wrapped her arms around my neck, leaning into me like she was surrendering her body.

“Let’s kiss…♥♥♥”

“Sure.”

Naturally, I accepted her.

“…Nfufufu♥♥♥”

Giggling softly, she aligned her slightly parted lips with mine.

“Chu!♥♥♥”

The kiss began, and instantly—

“Chuuu~!♥♥♥”

She started sucking on my lips, my tongue.

This time, she initiated the kiss.

And the deep kiss was forced by her, though I started it.

I was the first to slip my tongue into her mouth.

“~Nha!♥♥♥ Delicious!♥♥♥ Ren-chan’s tongue…♥♥♥ So tasty!♥♥♥”

Though it shouldn’t taste like anything, she called my tongue delicious, sucking it eagerly.

Soon, her own tongue began licking mine, savoring it, moving slickly inside her mouth.

“Ren-hyan!♥♥♥ Chupi!♥♥♥ Hyaichu!♥♥♥”

Eyes narrowed lovingly, she cried out with sultry moans, devouring my tongue and mouth.

Hot.

…Swelteringly hot.

In this confined space, heat and humidity swirled endlessly.

My foggy mind and blurred vision finally started to refocus.

“Haa…♥♥♥ Haa…♥♥♥”

Warm air brushed my face.

“Nuu~!♥♥♥”

Something grazed my lips.

“—Chubu!♥♥♥”

Something warm and wriggling slipped between my lips into my mouth.

Reflexively, I accepted it… her tongue.

At the same time, I slid my own warm tongue into her mouth.

“Nn!♥♥♥”

My tongue was enveloped by her warm flesh.

From deep within, sultry moans rose, her flesh trembling with joy.

“Nchu…♥♥♥ Chubu!♥♥♥ Ha…♥♥♥ N…chu…♥♥♥”

Relishing, delighting, we devoured each other’s flesh… our mouths.

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

Breathing heavily, Yuu—right in front of me—kept calling my name.

“Ren…cha…♥♥♥ Ren…chan…♥♥♥ Ren, cha…♥♥♥”

It was a whisper of love, a sultry moan, a decadent call.

Like a soothing swamp, an abyss of thoughtlessness, trying to swallow me whole.

With overflowing lust and love, melting body and soul into mush.

We kept devouring each other.

Relentlessly.

“…Ngh. Wait… did I fall asleep?”

Slurp…

My mouth and chin felt wet, yet my skin was dry, exposed to unnecessary dehydration. Completely soiled with saliva… a vividly raw sensation.

Still bound at all four limbs, propped up on the reclining bed.

After exchanging heated kisses with Yuu, I must’ve fallen asleep, I realized.

“We were kissing—wait, Yuu?”

I felt a warm weight and humidity pressing against my front.

It was Yuu.

“Su… su… su…”

Her head rested on my shoulder, breathing soft, peaceful snores.

She was asleep too.

In a face-to-face position, her relaxed body leaned fully into me.

Like she’d fainted, she was sleeping deeply.

Her left cheek pressed against my left shoulder, her breathing gently moving her shoulders.

Strands of her long black hair stuck to her sweaty neck, like a scene after intense exercise—or post-coitus.

Yet, my feelings were… tender.

Like a parent watching their exhausted child sleep. I don’t know that feeling yet, but I imagined it might be like this.

A fulfilled, calm warmth.

“…Not bad.”

The act itself, continued until we slept, was abnormally intense.

But afterward, a sense of accomplishment, satisfaction, or pleasant exhaustion settled in. Freshly awake, my mind was clear.

“…Really, not bad…”

Still, I focused on a sensation against my upper body.

From tender observation to being pulled in, leaning forward.

Even through her bra and shirt, I felt the soft swell of her chest. No surprise there.

But damn, it felt good.

Maybe I could stay like this a while, I thought sweetly.

“…No, wait. What time is it—?”

Glancing at her room’s clock, I saw it was just past noon.

“Three hours since we started kissing!? No way!”

…Terrifying.

How long were we kissing?

Or when, mid-kiss, did we pass out from exhaustion? No way to tell.

But we burned a lot of time on kissing.

With her lust and restraint completely broken, she’s demanding a “raw creampie” or I’ll face a shotgun wedding. Twelve hours left. If I don’t fix my impotence by midnight, I’m on the path to a student marriage.

Whether I can cure it by then is… iffy.

How do I even fix it?

…Wait, until last week, I was impotent, but around when Yuu and I became official, I recovered, right?

Looking back, analyzing that might give me a clue.

“Hmm…”

Last Saturday, date night…

Even though she drugged me with an aphrodisiac, I roughly took Yuu’s virginity shortly after she lost it.

“Aphrodisiac…”

I’ve experienced that state.

It was intense…

I ended up thrusting behind a convulsing, moaning Yuu until morning.

My crotch—or me—was consumed by uncontrollable desire. Terrifying.

It was caused by her homemade aphrodisiac, and its effects were insane.

I don’t know about market drugs, but I bet there’s something as potent—or more—out there. My impotence can likely be cured with drugs.

But since I go wild on aphrodisiacs, I need to be careful, a lesson learned.

…But.

“…Wait a sec…?”

Drugs work, sure, but I realized something crucial.

Before the aphrodisiac… when I first had sex with Yuu.

I was erect without drugs.

And before that, during some heavy physical contact with her, I got hard too.

“…”

I was mildly impotent, not severely.

It’s psychological—mental fatigue from a stressful life, a kind of mental illness, a dip in libido.

Yuu saw through it and called it out perfectly.

And it’s a condition that heals.

Going back further, early last week makes it clear.

When my underwear was auctioned off and we went to Yakko’s house after school, I got hard from accidental contact when she collapsed at her door.

My impotence was already nearly gone then.

After Yuu saw my erection and questioned its severity, she acted immediately.

That night in my room, we confirmed it was healing. Her initiative is unreal.

“…”

So, basically.

My penis, once mildly impotent, recovered.

…No.

It’s obvious why it recovered.

Yuu.

It’s all thanks to her devotion.

Diet control, better sleep, improved lifestyle.

Listing her influence, it makes sense.

It’s simple in hindsight.

It’s pathetic I didn’t see it sooner, but still.

So, my current situation mirrors that past, where her efforts improved my life.

Plus, she’s been feeding me libido-boosting foods, so my vigor should be stronger—the opposite of impotence.

So.

“…My impotence might already be cured…?”

Maybe I can get hard.

I just need a trigger.

“A trigger…”

Last week, like I said, Yakko’s incident sparked an erection, surprising me and alerting Yuu.

My challenge now is finding a trigger to release the pent-up energy I likely have.

“…And then.”

There’s another issue.

Yuu, with her insane initiative, already knows what caused my near-impotence.

She likely sees my sister Shiori as a barrier to our intimacy.

Something happened between them recently. Yuu’s extremely averse to other females near me. Given her recent odd behavior and personality, she might view Shiori as an enemy.

…Weirdly, if I don’t get hard and creampie her, things could spiral unpredictably.

Wait, is this situation more dire than I thought…?

“Nn… Ren-chan…?”

Yuu stirred, lifting her face from my chest.

Pausing my thoughts, I watched her rub sleepy eyes.

“Ren-chan…♥♥♥”

She grinned weakly, happily.

Sleepy and adorable.

“Jeez, what a mess. I’m all sticky.”

I gave her a wry smile, watching her slowly wake up.

“—Ah!? I fell asleep mid-kiss—!? Sorry, Ren-chan!”

“It’s not something to apologize for.”
