A Mistake, Held in Your Arms ~ I Don’t Want to Marry My Matchmaking Partner, So I Will Offer My Virginity to You ~ - Extra Story 2

Clad only in a thin yukata robe, Hina rinses herself under the bathwater.

The fabric soaks up the water, clinging to her skin as if drawn to it.

She should have felt comforted by the coverage, but now that it’s wet, it might as well be nothing at all. The summer night air is pleasant, but the soaked yukata quickly turns cold, sending a shiver through Hina’s small frame.

(Maybe I should just take it off…? But this is the first time we’re bathing together…)

As she hesitates, torn between embarrassment and the thought that once she’s submerged, it won’t matter, her toes touch the edge of the open-air bath.

Then, from beyond the steam, comes the sound of quiet footsteps.

Turning, she sees Keiichiro—without his glasses. His face looks slightly younger than usual, and Hina’s chest tightens at the sight. While she’s wrapped in her yukata, Keiichiro wears nothing but a towel around his waist.

His gaze lingers on her chest for a moment before he looks away.

“…This is somehow worse than bare skin. I don’t know where to look.”

At his words, Hina instinctively glances down.

The soaked yukata clings to her, faintly outlining the curves of her breasts. The peaks stand taut, clearly visible even to her, and she nearly chokes on her breath.

“Ah… please don’t look too much…”

She crosses her arms over her chest and turns her face away, but Keiichiro gently pulls her hands aside.

“You’re freezing.”

“I rinsed myself, so…”

“Sit here.”

His deep voice guides her as his large hand rests on her shoulder.

Led by his touch, Hina settles onto the wooden bath stool.

When she rinses herself again, the faint scent of flowers drifts through the air.

Looking back, she sees Keiichiro carefully lathering soap between his palms.

This soap, too, was provided to Yunoya by Saotome Pharmaceuticals.

White suds fall silently onto the stone floor.

“…Let me wash you. Before you soak.”

“K-Keiichiro-sama…! N-no, I can—”

Before she can finish, the tie of her yukata loosens, and the fabric slips from her shoulders.

The wet cloth, tugged just slightly, sends a chill down her spine.

Yet despite the cold, her cheeks burn, and her exposed skin stands out starkly white against the steam. She feels Keiichiro’s breath against her back.

“Wearing this just makes you colder.”

“But… it’s proper etiquette to wear a yukata in the bath…”

“You don’t need it in front of me. Right?”

With those words, Keiichiro presses a light kiss to her bare shoulder.

His soap-lathered hands glide down her back without hesitation.

With every slow, circling motion, the scent of soap tickles her nose.

Usually, she’s the one tending to his old wounds, carefully applying medicine to his back, wishing she could ease his pain. Now, the roles are reversed.

His palms stroke her skin gently, warming her inch by inch.

A mix of ticklishness and embarrassment rises within her, making her tremble.

(No… He’s just washing me…)

The nape of her neck, her shoulders, her shoulder blades—each spot is meticulously cleansed, and with every touch, heat pools deep inside her.

When his soapy fingers graze her side, she flinches.

“…!”

Keiichiro doesn’t miss her reaction.

His hand glides smoothly along her skin, caressing the side of her breast.

“Keiichiro-sama… you’re just washing me, right?”

Her voice trembles as she asks, and Keiichiro nods with a faint smile.

“Of course. Thoroughly.”

The moment he speaks, his fingers pinch her nipple.

“Nn… ah…!”

Rolling it gently between his thumb and forefinger, he draws a gasp from her.

“Ah…! You said just washing…!”

“I am. This part needs extra attention.”

“Aahn!”

Just as she thinks he’s merely tracing around the peak, his fingers rub the underside—right at the sensitive border—and her body shudders violently.

An endless, tiny pleasure. Yet it’s more than enough to set her entire body aflame.

“Ah… ah…”

Small, breathy moans escape her.

Even her own voice feels foreign.

Why does every touch send her heart into such turmoil?

More than embarrassment, a sweet, soothing sensation fills her chest.

Soon, Keiichiro’s hands drift lower.

He washes around her navel with care, then strokes her hips and backside, spreading warmth.

“Haha… that tickles…”

“Does it?”

Perhaps drawn in by her smile, Keiichiro’s eyes soften as he kisses her temple.

Just when she thinks he’s nearly done, his fingers slip between her thighs.

“Ah, there—I can do that myself—”

“Yourself? You’ll wash there in front of me?”

“Th-that’s not what I—nn!”

Before she can protest, his fingers brush against her most sensitive spot.

She hadn’t noticed before, but between the water and soap, she’s already slick.

“You’re so wet, you don’t even need soap…”

“Ah…!”

He carefully washes around her petals, then slides a finger upward.

When it reaches her core—

“Haaahn!”

Her hips jerk involuntarily.

As he teases her, his other hand glides along the side of her breast.

“I read in a medical book that massaging here is good for the body.”

The perfect balance of gentleness and stimulation leaves her speechless.

(Ah… ah… It’s not just down there… My chest feels…)

Unable to resist the pleasure, her body goes limp.

Whether from the massage or not, the sensations soon gather at her peaks—and just as she’s about to lose herself, Keiichiro pinches her nipple sharply.

Her entire body convulses, her legs stretching taut.

“Ah! Aah—ahh!”

Unlike climaxing from just her core, this heat runs deeper, wrapping her in a strange exhilaration.

For a while, all she can do is lean against Keiichiro, catching her breath.

“Y-you said… just washing…”

“Haha, my bad. You were just too cute.”

By the time he finishes, her cheeks are flushed. The warmth lingers, seeping into her very core.

She thinks soaking in the water might calm her down—but the moment they sink into the bath together, Keiichiro’s arms slide around her from behind.

“Don’t want you getting cold.”

Holding her close, his large hands envelop her shoulders, his breath warm against her back.

Once again, that sweet, herbal scent fills the air.

“Keiichiro-sama…?”

“…There’s something I want to try.”

He uncorks a small vial—hidden in the bucket, it seems.

On its golden label, written in familiar script:

Saotome Pharmaceuticals – Special Moisturizing Oil (Warming Effect Included)

“This is…”

“It’s still a prototype. But it’s safe.” He tilts the vial, letting thick liquid drip into his palm. “It makes the skin more sensitive. Improves circulation—in short, an aphrodisiac.”

She gasps.

The scent intensifies as the oil mixes with the steam.

“When did you even—”

“Do you mind?”

She hesitates. Is this part of his work, or… is he treating her as a woman? She doesn’t know how to answer.

But part of her doesn’t care either way.

If it’s Keiichiro, she could never refuse.

“…I don’t mind.”

Her whisper is nearly lost in the sound of flowing water.

Lifting her chin, he brushes his lips against hers, confirming her consent.

“Let me try it, then…”

The oil drips slowly, landing on her skin before his hands even touch her.

When it reaches her chest, heat blooms there—as if her body is waiting for him.

“…How does it feel?”

“It’s… tingling…”

Her nipples stiffen further, more sensitive than before.

“It’s hot…”

His oil-slicked hand traces from her shoulder to her breast, following every curve.

With every stroke, her pulse races there, her breath hitching, her chest rising on its own.

“…!”

Even just being touched like this—it’s overwhelming.

And when he flicks her nipple lightly—

“Ah…!”

Her shoulders jerk, her back arches. She can’t control her own body.

Captivated by her reactions, Keiichiro rolls, pinches, teases.

“Aah! Ah, nn… aahn!”

She never knew she could change like this—her legs tremble uncontrollably.

How can just her chest make her—? Her lower abdomen throbs.

The water splashes as her hips move involuntarily.

“To think you’d unravel like this… It’s working perfectly.”

As he toys with her, his lips brush her ear, whispering.

“Ah… don’t say that…”

His mouth trails kisses along her ear, her temple, her cheek.

She closes her eyes.

Their lips meet, the kiss deepening, lengthening.

When their tongues tangle, her hips jerk again.

She comes—just a little.

But even after, the aphrodisiac’s effects linger, her nipples still aching.

Breathing shallowly, she leans into him.

“I want to touch you more… but we’ll overheat.”

“Should we get out?”

“Yeah…”

Yet even as he says it, his hands slide to her hips, guiding her forward.

Before she can react, she’s bent over the stone edge of the bath.

“This is… embarrassing…”

“Let me try this, too.”

“Eh?”

Before she can turn, she hears the vial uncork again.

The aphrodisiac drips—right onto her most intimate place.

The cool liquid trickles down, quickly turning hot inside her.

Her core pulses, clenching on its own.

“You’re already twitching. Can’t wait?”

“S-stop teasing me!”

Ignoring her protest, his arms wrap around her from behind.

His fingers slide between her thighs, stroking her slick folds.

“Fah!?”

Just that touch makes her hips buck.

Her swollen bud throbs, desperate for more.

Then his middle finger parts her entrance, sinking deep. His thumb circles her clit, relentless.

“Ahh! N-no…! Too much…! Aahh!”

Even as she writhes, he doesn’t let her escape. The lewd, wet sounds only heighten her shame.

His fingers are persistent but never rough—finding every weak spot.

When a second finger joins, stretching her, stroking upward—

“Ah! Aah…! No…! Keiichiro-sama!”

Her desperate cry makes him pause. Normally, he’d push her over the edge—but not this time.

“No… I don’t want… Keiichiro-sama… with me…”

Still bent over, unable to turn, she pleads with her body.

She wants them to finish—together.

For the first time, she voices it.

Keiichiro exhales sharply, pressing a kiss to her back.

Then, his hardened length presses against her entrance.

“…I can’t hold back anymore.”

His whisper sends shivers down her spine.

“Yes… please…”

More than shame, anticipation swells within her.

His arms tighten around her waist as he pushes inside—slow, deep, filling her completely.

“Ah… ah—!”

A moan escapes her.

His burning heat spreads through her, inch by inch, until he’s buried to the hilt.

“…Ah, Hina…”

His low voice trembles against her back.

Just that makes her clench around him.

When he finally bottoms out, she clutches the yukata draped over the edge, gripping it tightly. Her whole body feels like it’s melting.

“Nn… ah… ahh…”

Bubbles rise where they’re joined, rippling the water’s surface.

Whether from the aphrodisiac or the memory of his fingers—

Every thrust makes her feel possessed.

Slow, relentless rhythm.

His hands grip her hips, holding her in place as he drives deep.

“Ah…! Aah…! Too… deep…!”

The obscene, wet sounds fill her ears.

Each stroke sends sparks through her, her walls clinging desperately.

“Hina, don’t squeeze… so tight… You’re…”

“N-no…! It’s not… me…!”

Despite her denial, her body clenches around him.

Keiichiro groans, his thrusts growing erratic.

“…You’re not… letting go…”

“Ah…! Because…!”

Her insides burn, her core trembling with every movement.

“Ah… ah…! Again…!”

A small, explosive pleasure bursts inside her—then another, and another.

“Hina… I’m… close…”

His voice shakes, his abdomen tensing against her back.

She feels him pulse inside her, his tip swelling.

“Come… with me…”

“Ah—ahhh!”

Water splashes as her consciousness shatters.

White-hot pleasure drowns everything out.

She can’t tell her own cries from his growls—

They fall together.

Even after, her body trembles with aftershocks.

Her core still clenches around him, sensitive and throbbing.

When he finally pulls out, she turns to look at him—

Only to find him still hard.

“…Hey, Hina. Once more…?”

His voice is rough with desire.

Blushing, she leans into his chest.

Their eyes meet—his usually calm gaze now dark with need.

His arms tighten around her waist.

“The aphrodisiac’s… too strong. I can’t hold back.”

Her heart skips a beat.

The very fact that he would desire her like this—it tickled her heart unbearably, filling her with overwhelming tenderness. Their heartbeats overlapped, and in that alone, she felt as though they had become one.

“Yes… Um… I’m also still…”

Before she could finish, her lips were sealed.

Deeply, each time their tongues intertwined, sweet moans escaped from the depths of her throat.

Once more, Keiichiro’s length slowly sank into Hina. Deeper than before, as if confirming each other.

“Mmm… ah… Keiichiro-sama, more…”

Hina’s slender arms wrapped around Keiichiro’s neck.

Keiichiro gripped her waist, deliberately grinding against her deepest reaches.

“Hina… don’t you dare pull away from me…”

“Yes… I won’t…”

The sound of wetness, sweet gasps, and warmth melting together.

Though the night had long since deepened, their time alone refused to end.

In this place where no one could disturb them, they engraved that promise—over and over again.
