CHAPTER 18: [R-18] HUSH... YOUR MOTHER’S SLEEPING

The room vibrated with a deceptive silence, broken only by the creaking of a beam and Ayame’s steady breathing. Her body, wrapped in the damp fabric of her half-open kimono, stood out against the gloom like a sleeping statue. Her heavy chest rose and fell in a slow, almost hypnotic rhythm, a cruel contrast to the fever burning in my loins.

I was suffocating. Hikari was relentless, her lips pressed tightly around me, each suck resounding like a wet slap in the dampness of the room. Her frail body trembled with an excitement she could barely contain. Her fingers gripped my thighs with feverish strength, as if I could still escape. But I didn’t dare move. Not when, just a few steps away, her mother slept in a fragile peace.

I turned my head in spite of myself. The torchlight coming through the window brushed Ayame’s face, her eyelashes set like shadows on her cheeks, her lips parted with a calm breath. The contrast tore at my guts: peaceful innocence on one side, feverish obscenity on the other. My throat tightened, my voice burst out, broken, breathless:

"But... your mother is here... right here..."

Hikari didn’t stop. Her breath vibrated against my skin, hot, burning, and I felt her tongue accelerate in an almost cruel movement. Then she pulled away abruptly, a string of saliva dripping from her swollen lips. Her red eyes, shining with a dangerous fever, bored into mine. She licked her lips slowly, as if to swallow the rest of my sanity.

—"Mom’s always been a heavy sleeper..." she breathed, her voice raspy with suppressed excitement. "Don’t worry..."

She moved up slightly, her face so close that I felt her warm breath whip my cheek. Her fingers were still trembling, but her smile widened, nervous, almost predatory.

—"And if we get caught..." Her lips pursed, her stifled laugh vibrating like a provocation. "...it’ll be your fault."

Her nails dug into my hip, and her pelvis pressed against mine with feverish brutality. Then, in a low whisper, more intimate, sharper than an order:

—"Now... take responsibility."

I stood there, breathless. Between Ayame’s fragile serenity and Hikari’s feverish gaze, I was nothing more than a puppet, stuck on the edge of an abyss where danger and desire intertwined.

Fear, guilt, the bitter taste of danger... everything mingled, but instead of stopping me, it made me tip over. As if my panic were just another fuel for this madness. My body reacted before my mind: my hands gripped Hikari’s hips and, with a sudden movement, I knocked her over. A surprised gasp burst from her throat, cut off by the moist sound of her mouth still sucking on my cock.

I half-lifted her, her white thighs trembling against my arms, and her pelvis tilted until it crushed my face. Her scent burst forth, strong, burning, a mixture of sweat, desire, and the wetness she no longer even tried to hide. Her dripping pussy brushed against my lips, and before I had time to think, my tongue slid between her glistening folds.

Hikari moaned immediately, a strangled sound, muffled by my cock, which she was still swallowing. Her fingers tightened on my thighs, her nails digging into my skin through the fabric. She sucked harder, her cheeks hollow, her ragged breaths echoing like a plea.

I responded by redoubled my licks, plunging deeper into her sticky heat. Every movement of hers was mirrored in mine. The more her mouth swallowed me, the more my tongue tore at it. The faster she moved, the more I swallowed her. A filthy mirror, a reverse dance where each sought to break the other with pleasure.

Her moans, muffled by my shaft, vibrated down to my very core. Her pussy trembled, already convulsing with nervous spasms, and the salty, feverish taste dripped onto my tongue. Her thighs closed around my head like a trap, but I no longer wanted to flee.

I gasped, drunk on a mixture of shame and ecstasy, unable to know which of us would give in first. Each stroke of my tongue triggered a more brutal suction, each gulp forced me to devour her more. We were nothing more than two beasts, locked in this vicious circle, beneath the peaceful breath of Ayame, still sleeping a few feet away.

I suddenly toppled over, unable to hold back the tide engulfing me any longer. Hikari stifled a cry of surprise when I flipped her under me, her back slapping against the damp sheets. Her red eyes, bright with fever, widened just before my lips crashed down on hers. The kiss was rough, breathless, clumsy. Our tongues collided immediately, a mixture of saliva and gasps torn from panic.

Her body arched, trembling, her thighs spreading apart despite herself. I felt her burning pussy beneath my hips and, without thinking, I plunged into her in one swift thrust. Her throat burst into a muffled cry, which I immediately muffled with my palm. Her gaze blurred, flooded with tears and a mixture of pleasure, and her entire body writhed beneath me like trapped prey.

"Hhhhnnn..." she moaned against my fingers, her eyes closed in pain and ecstasy.

Her hands gripped the rough sheets of the fortress, pulling them until her knuckles turned white. Her teeth sank into her own fingers, trying to stifle the cries that threatened to betray us. I felt her stomach convulse beneath me, her tight walls engulfing me in an uncontrollable spasm.

My breath caught, my eyes turned in spite of myself towards Ayame’s silhouette. Still motionless. Still asleep. Her chest heaved calmly in the darkness, indifferent to the hell unfolding a few meters away.

"Shh... sleep... damn, sleep..." I breathed hoarsely, my words meant for her, for Hikari, and for myself.

But Hikari wasn’t asleep. She was alive, burning, writhing beneath me. And the more she struggled against her own moans, the more her body betrayed me by clinging to mine.

My pelvis bucked in spite of myself, each thrust sharper than the last, each shock louder in the muffled silence of the room. I wanted to slow down, I wanted to stay in control, but my body was no longer listening. Hikari’s moist heat swallowed me whole, her walls pressed against me as if they refused to let go. Her breaths hitched beneath my hand, her muffled moans vibrated in my palm, and I felt each one rise to my nerves.

I gasped, my lips trembled above her ear, and suddenly I spat out, unable to hold back the confession:

"I’m going to... I’m going to come..."

My words felt like betrayal. I panicked for a second, casting a desperate glance at Ayame’s figure, curled in her sheets, still asleep. The contrast almost broke me: the peaceful sleep of a mother just a few steps away, and the burning body of her daughter secretly calling for me.

Hikari, however, flinched. Her red eyes clouded with a mad glare, and with a broken, gasping breath, she begged me:

"This is my safe time... come inside me... I beg you..."

Her words pierced me. No more holding back. No turning back.

I dug my fingers into her hips, my pelvis ground harder against hers, and the explosion caught me by the throat. I felt her convulse at the same moment, her body shaking beneath me like an overtightened rope. Her thighs clamped violently against my sides, her nails scratched the sheets, and her back arched in a perfect arc.

A strangled cry, drowned out by her bitten hand, burst out as her sex contracted around mine, wringing the last drops of strength I thought I was still holding.

I came inside her.

Brutally. Completely.

And in that same flash, I felt her come too, her spasms swallowing me in a liquid heat, her tears rolling down her cheeks, her hair plastered to her forehead.

Her body and mine burst together, bound in that burning shame, that dizziness that devoured us despite the fear, despite the guilt.

I stopped thinking. My body, heated by this shameful fever, acted on its own. I grabbed her hips, and with a hoarse breath, I tipped her forward. Her trembling arms broke her fall, her knees sank into the mattress, and her back arched in spite of herself.

Hikari gasped, her hair sticking to her flushed cheeks, her lips trembling. I put her on all fours, her face forcibly turned towards Ayame’s sleeping figure. The shadow of her sleeping mother filled the room like a silent threat.

I leaned down, my lips almost pressed to her ear. A whisper, crueler than anything I’d said before:

"Watch your mother... while you’re being fucked by your stepbrother..."

I thrust into her suddenly. Her cry burst out, strangled, muffled by her own hand, which she bit down on with gusto. Her body tensed like a bowstring, her thighs trembled, and I felt it: her sex was clenching violently around me, as if her insides wanted to suck me in.

Her reddened eyes twisted in shame, but her hips were already undulating against mine. Her broken moans, swallowed by her palm, vibrated throughout my body.

And I understood.

It was turning her on.

Not just me, not just the forbidden. But this monstrous game: his mother asleep just a stone’s throw away, the risk of being caught, the weight of the transgression. That was what electrified him, what tightened his grip on my cock to the point of suffocating me.

An icy shiver ran down my spine. My shy little sister, the one who looked away at the slightest crude word... was a real nymphomaniac.

And me... I had just given in completely to my desires.

I pulled her upright without thinking, my hands clenching on her burning hips. Her back pressed against my chest, and I pulled her towards the bed, where Ayame slept peacefully, oblivious to the hell unfolding just a few steps away.

Hikari immediately stiffened, her fingers trembling on my arm.

"No... not so close... please..." she breathed, her voice breaking.

Her words spoke of fear, but her body... her body betrayed me. Her thighs quivered, her back arched in spite of herself, and each jolt made a more intense heat surge against my skin.

I gritted my teeth. The more I resisted, the more I lost myself. So I broke down the last barrier.

I took her harder, my thrusts echoing in the dim darkness of the room. Her mouth opened on a muffled moan, her teeth sinking into her own hand to hold back the cry. Her shadow-filled eyes glowed with fever, red like two embers begging to be consumed.

"Touch yourself," I breathed, my voice hoarse, choked with tension.

She hesitated for a second, her breath coming in ragged gasps, then gave in. Her feverish fingers slid between her thighs, rubbing her clitoris in time with my thrusts. Each movement drew a small, strangled cry, muffled in the palm of her hand.

— "Hhhhnnn... Nii... san..."

I bit my lip, my hands pressed against her hips to impale her deeper. The obscene sound of our bodies mingled with the rustling of the sheets, Ayame’s steady breathing nearby, unconscious.

And then it exploded.

Her body contracted violently, her thighs trembling against mine. A hot jet spurted from her, splashing the sheets of her mother’s bed. She convulsed silently, her face contorted by an uncontrolled orgasm, her nails digging into my skin.

I spat out a muffled curse and immediately followed her. My stomach tightened, my seed spilling into her in a series of desperate thrusts. I pounded into her until my legs gave way and her body collapsed, shaking with spasms.

We remained pressed together, trembling, panting, the sticky smell of sex already permeating the heavy air of the room. Hikari let her hand slide down the back of my neck, her lips brushing my ear with a breathless whisper:

"Thank you... Nii-san..."

Then she tore herself away from me, feverish, barely adjusted her kimono, and disappeared into the hallway.

I remained sitting on the edge of the bed, the sheet hastily pulled over my hip, my heart pounding like a drum. I tried to catch my breath, to understand what I had just done, but my thoughts immediately crashed against an icy wall.

When I raised my head, my guts froze.

Ayame.

Her eyes were open. And she was staring at me.
