[Sakuramachi General Hospital Rooftop ]
The evening air carried the iron-tinged scent of rain-slicked concrete mixed with antiseptic that had seeped into everything on this rooftop. Riku stepped forward and kicked away the strange syringe that had fallen from the unconscious doctor's hand, watching it skitter across the weathered concrete with a hollow clatter.
The fluid inside shimmered pink under the flickering emergency light—definitely nothing good.
To prevent any surprise counterattack, Riku delivered another solid kick to the doctor's head. Perhaps excessive, but one look at that greasy, pockmarked face stirred an almost Bakugo-level urge to add two more for good measure.
He left Tachibana—the nurse—bound for now.
Instead, he approached the rooftop door, grasping the cold metal handle.
Locked. From the outside.
Where's the key?
Suppressing his revulsion, Riku crouched beside the unconscious doctor. The smell of stale sweat and cheap perfume hit him immediately—like someone had marinated themselves in a konbini clearance bin. His fingers searched through pockets, finding only a small keyring and... a pink remote control.
One button. Just one.
"What's this button for?"
「This is—」
Before the narration in his head could finish, Riku pressed it.
Beep.
A low buzzing sound hummed across the rooftop.
Bzzzzzzz...
"Mmph~! Nngh~!"
Tachibana's muffled voice rose behind him—strange, trembling notes escaping around the ball gag. But the rubber sphere swallowed most of the sound, leaving only vibrations in the air.
Riku hadn't yet connected the dots. He turned toward the source of that buzzing.
Tachibana sat bound to the chair, her face flushed deep crimson now. Her body trembled visibly, shoulders jerking in small spasms. Her chin dropped toward her chest. Saliva pooled around the red ball gag, dripping in thin strings onto the generous swell of her breasts straining against her nurse uniform. Muffled whimpers—mmph, mmph, mmph—escaped continuously.
「You've discovered quite the device. With this button, you can easily control the nurse bound to that chair. You consider turning it to maximum output...」
The realization hit Riku like a truck.
He rushed to her side immediately.
"Sorry—sorry! I didn't mean to!"
His fingers worked the ropes first. The moment the bindings loosened, Tachibana's hands shot down to grip her own thighs, knuckles white. Her whole body shook—not stopping, not slowing.
Trembling. Trembling. Trembling.
I can't... not in front of him... but it won't stop...
Riku moved in front of her, reaching behind her head for the ball gag's clasp. The leather strap had been fastened tight—that disgusting doctor really knew her kinks.
The moment the clasp released—
"AAAHN~!"
Tachibana's body seized violently. The sounds she'd been holding back burst free—wet, desperate, completely uncontrolled. Each moan climbed higher than the last, echoing off the concrete walls surrounding them.
She can't control it.
The realization sent heat rushing through Riku's entire body. He fumbled for the pink remote.
Turn it off—how do I turn it off?!
One button. He pressed it again.
BZZZZZZZZ—
The vibration intensified.
"HYAAA~!"
Tachibana launched herself forward, slender arms—pale as lotus root—wrapping around Riku's torso. Her fingers splayed rigid against his back, nails digging in through his shirt. The sounds pouring from her lips grew wetter, more broken.
Shit!
Riku's blood ran hot. He jabbed the button again.
"S-Sorry—!"
BZZZZZZZZZ—
Maximum intensity.
Tachibana's legs gave out completely. Her full weight collapsed against him, soft and warm and shaking uncontrollably. Her eyes had gone glassy, unfocused. Drool escaped freely now, dampening his shoulder. Her breath came in ragged gasps against his neck.
"Too... too... f-fast...!"
Each broken syllable vibrated against his skin. Riku's self-control crumbled like a sandcastle against the tide.
Wrong again.
He pressed once more—
Click.
The buzzing stopped.
But Tachibana didn't stop.
Her hips ground against him with increasing desperation, seeking friction, seeking completion. The vibration had ceased at the worst possible moment—right at the edge.
"I... I can't..."
"It hurts... it hurts so much..."
"Please..."
I was so close... I need... I need it...
Her voice had transformed—no longer just trembling but thick with need, dripping with desperate invitation. She'd stopped processing anything except the aching emptiness between her thighs.
"Please... please please please..."
「Congratulations! You've discovered this device's true purpose. The girl can't take anymore. Simply push her down, tear open those clothes, and enjoy her thoroughly. For the hospital's reputation, she'll never speak of this...」
「With just one remote, you've conquered this maiden. Perhaps she deserves a little lesson. You begin slowly removing her clothes...」
Honestly?
Riku had reached his limit.
The combination of Tachibana's desperate grinding, those lewd sounds, the warmth of her body pressed against his—his higher brain functions had checked out entirely.
His hand moved on its own, pressing the button once more.
Tachibana's nurse uniform hung open from earlier—when that doctor had been... preparing her. Riku's left hand traced down the smooth skin of her back, fingers finding the clasp of her bra.
One-handed technique: click.
Released.
He felt everything now—her softness pressing against his chest without barrier. His palm cupped yielding flesh, finding it surprisingly firm compared to Yukigami's pillowy softness. Different texture entirely—more resilient, perky, springing back against his palm.
Yukigami's were bigger... softer... like mochi. But these...
"S-Save me... please..."
Tachibana's tear-stained voice broke through, pleading directly into his ear.
Riku pressed the button one final time.
The buzzing died completely.
But her body had passed the point of no return.
She ground against him harder now, friction-seeking movements growing erratic, uncoordinated. Her nurse skirt had ridden up completely, pale thighs squeezing around his leg as she rutted shamelessly.
"I can't... I can't take it..."
"So empty... please..."
"Please please please..."
Give it to me give it to me I'll die I'll actually die—
The buzzing had stopped mid-crescendo. Her body screamed for completion it couldn't achieve alone.
"I'm begging you..."
That's it.
Riku broke.
A gorgeous nurse grinding against him, begging, crying, completely lost to pleasure—
He wasn't a eunuch!
His right hand released the remote. Both arms moved with purpose now.
Then—something wet traced along his neck.
Tachibana's eyes had gone completely hazy. Her lips—slick with drool—pressed soft kisses along his throat. When he didn't respond fast enough, she grew bolder, tongue dragging hot and wet against his pulse point.
Lightning shot down Riku's spine.
His hands gripped her arms.
Pulled her back.
Crushed his mouth against hers.
Their first kiss—if you could call his collision with Yukigami a kiss—had nothing on this. Tachibana responded immediately, desperately, her tongue pushing forward before he could even initiate. She kissed like she was drowning and his mouth contained the only air left in the world.
Wet. Hot. Hungry.
Their lips and tongues tangled together sloppily, saliva mixing, breaths mingling. Tachibana's eyes had fluttered completely shut, small whimpers escaping into his mouth with each clash.
Heat coiled tight in Riku's gut, pressure building with nowhere to go.
No good.
I can't hold back anymore!
