It was after 10:30 PM when I texted my brother to come to my room. The door creaked open, and he stepped inside.

I was already in costume — the tiny, tight, red-and-blue Harley Quinn getup I’d picked up for that party next weekend. But I couldn’t resist trying it on tonight… just to see how slutty I looked.

And filthy was an understatement.

The crop top barely contained my tits, the shiny hot pants hugged my ass so tight they looked sprayed on, and plenty of cheek was hanging out. The fishnet stockings clung to my legs, smooth, tan thighs peeking out above them, practically begging for attention — and he was going to see every inch of it.

His eyes roamed my body, top to bottom, slow, dark, hungry.

“Holy shit…” His voice was low, thick with lust as he stepped toward the bed, stripping his shirt off on the way. “You look fucking amazing.”

I smirked, shifting on the bed, spreading my legs just enough to tease him. “Like?”

His eyes darkened. His shorts hit the floor — cock swinging like a pendulum as he knelt onto the mattress.

“You’re in so much trouble.”

Before I could sass him back, his mouth crashed onto mine — hungry, rough, tongue sliding between my lips as his hands found my hips, fingers slipping under the waistband of the shiny hot pants, brushing across my bare, smooth pussy.

“Fuck… you’re wet already,” he groaned, pulling back just enough to look down at me, his fingers dragging through my slit. “Been thinking about this all night, haven’t you?”

I nodded breathlessly as his fingers teased lower, sliding two inside me — curling, pumping, working me open as his thumb circled my clit.

My back arched, hips rolling, thighs shaking as that orgasm built low in my belly — wanting it, needing it.

He slid lower, peeling my hot pants down, leaving me exposed, spread, his mouth finding my inner thigh — kissing, licking, teasing up until his lips brushed my pussy.

And then… his tongue.

That filthy, practiced tongue that had wrecked me so many times before.

He licked me slow at first — savoring — before flattening his tongue, dragging it up through my lips, circling my clit, then dipping lower, licking my ass as I writhed beneath him.

“F-fuck—” I gasped, fingers fisting in his hair, grinding against his face. “Eat that ass.”

That’s exactly what he did. His tongue circled my little brown asshole, licking it like he had so many times before. But tonight… was going to be different.

He groaned, the vibration sending shivers up my spine as his tongue worked me over, relentless, building me up fast.

It felt amazing — right on the edge — when he pulled back, wiping his mouth with the back of his hand, grinning as he grabbed his cock, stroking it.

“You ready for me yet, Harley?”

I barely managed a breathless, “Yes… but…”

“But what?”

“No pussy tonight.”

His brow furrowed. “What do you mean no pussy tonight? Why’d you want me down here then?”

I rolled over, arching my ass up, looking back at him. “Ass only tonight… dear brother.”

The look in his eyes was electric. He fucking loved anal — especially when he could really get after it.

“You look so fucking good like this,” he whispered.

I tossed him the bottle of lube. He slicked his cock up, what remained on his hand slipping between my cheeks, helping to prepare me for the onslaught to come.

His hands gripped my hips, dragging my ass high in the air, the shiny Harley Quinn hot pants tangled around one ankle.

“Look at this ass…” he groaned, squeezing, spreading me open. “You wore this costume begging to get fucked.”

I bit my lip, breathless, legs trembling as his cock slid between my cheeks, grinding against my butthole, teasing me. His hand spread me wider — his cock pressed against my asshole.

“Wait—” I gasped, heart racing as the thick, fat head nudged into my tight, puckered hole.

“You can take it,” he growled, voice rough, breath hot against my ear. “Just relax… you know you want it.”

And before I could protest again, he pushed — steady, firm — the fat head of his cock stretching me open, pushing in. I was so tight… but he forced himself inside.

“F-fuck—” I gasped, back arching, hands gripping the sheets. I lost my breath, dizzy — the pain shooting through my core, sharp, overwhelming.

The sound I let out wasn’t human — deep, dark, almost evil as I tried to inhale.

“God damn,” he groaned, hips grinding against my ass as he bottomed out — buried completely in my ass.

I struggled to breathe — stretched so wide, stuffed so full — but the pain melted into this filthy raunch, my body clenching around him as he started to move.

Slow at first — pulling back, pushing in — not letting me adjust, loving how tight I was.

The bed creaked, the headboard knocking against the wall as he drove into me, hands gripping my hips tighter, pulling me back onto his cock, as deep as he could be.

The costume made it even filthier — my tits spilling from the crop top, fishnets digging into my thighs as he wrecked my little butthole.

“Such a little slut,” he growled, pounding into me. “Bet you wore this hoping I’d fuck you stupid.”

I couldn’t argue.

“You better get started,” I shot back, breathless.

That did it. Rougher. Harder. He fucked me like he hated every ounce of me.

His hands were like a vise on my hips, dragging me back onto him, raw, relentless — hips slamming against my ass, cock buried deep, every thrust sending shockwaves through me.

I could barely breathe — every thrust knocking the air from my lungs, my little brown butthole clenching around him, that orgasm building.

“Harder, harder, keep going! Almost there!”

When the orgasm broke, it was earth-shattering — my entire body shaking.

“Holy fuck! That was… so intense.”

Still gripping my hips, his voice strained, “I don’t think I’ve ever felt you shake like that before.”

“You take it in the ass so fucking good,” he groaned, pounding me, the sound of skin slapping skin filling the room. “Your little ass was made for someone’s cock to ruin.”

I couldn’t answer — could barely think — aftershocks rippling through me, my pussy soaked, dripping down my thighs as his balls slapped against it.

He wasn’t stopping. His pace turned desperate — his cock swelling, balls tightening — he was close.

“You like fucking your sister in the ass? Come on… fucking cum in me,” I begged, wrecked, breathless. “Cum in my ass… fuck…”

That’s all it took.

He slammed in deep, hips grinding, cock pulsing as he emptied himself — thick, hot ropes of cum flooding my ass, thrusting through every shot.

When he was done, he left his cock buried inside me — just sat there, enjoying the view, the high.

We collapsed onto the bed, his cock still stuffed in my ass as we caught our breath.

Eventually, he pulled back, his cock slipping from my battered hole.

“Holy fuck… trying to blow out my O-ring?”

“Just giving you what you wanted,” he smirked.

I nodded, breathless. “Exactly what I needed.”

But I barely had time to recover, my body still trembling, when he grabbed a fistful of my hair, yanking my head back hard, voice low and filthy in my ear.

“You think I’m done with you?”

I barely managed to shake my head, pulse racing as his hand slid down, gripping my hip tight enough to bruise.

“No,” I gasped.

“Damn right you’re not.”

He turned me toward him, moving to the side of the bed, holding his semi-hard cock to my lips.

I gave him a look — what?

“Open up… help me get back up again.”

The look in his eyes was wicked — daring me not to.

I opened my mouth, taking him in. His hand held my head, pumping in and out of my mouth. His cock swelled, filling out in my throat until he was ready to fuck the shit out of me one more time.

Moving behind me, cock pressed between my ass cheeks, slick with my saliva — I tossed him the lube again.

“You like being a filthy little slut, don’t you?” he growled, dragging the head of his cock down, nudging my sore little hole. “And I’m gonna make sure you remember it.”

Before I could speak, he shoved forward — rough, brutal — splitting me wide all over again, bottoming out in one hard thrust.

“F-fuck!” I yipped, burying my face in the pillow, eyes rolling back from the shock.

His grip on my hair tightened, yanking my head back as he pounded me — no teasing, no building up — just brutal, relentless thrusts, cock slamming deep, balls slapping against my pussy.

“Such a filthy little whore,” he spat, driving in harder, the bed rocking under us. “Bet you’ve been waiting all night for me to use your tight little ass like this.”

I couldn’t speak — just raw, helpless moans as his free hand slid around, grabbing my tits, fingers pinching and twisting my nipples hard enough to make me yip again.

“Say it,” he growled, twisting harder, rolling my nipples as he slammed into me. “Say you’re my filthy little slut.”

“I’m— f-fuck— a filthy little slut!” I cried, body shaking as he used my stretched, wrecked hole, the brutal pace making my legs weak.

“Damn right you are,” he groaned, cock smashing deep, hair wrapped in his fist, my nipples throbbing, skin flushed and sweaty.

The ache, the roughness, the abuse — it pushed me to the edge of orgasm or tears, filthy humiliation making it worse.

“You love it,” he hissed, grinding deep. “Love getting your asshole used… love being my little cock sleeve.”

I whimpered, body clenching around him as he rutted in, cock swelling, his pace turning sloppy.

Two more body-shaking, mind-numbing orgasms ripped through me.

“You want my cum,” he groaned, fucking me hard, bruising my hips. “Gonna cum so deep into your guts.”

I couldn’t answer — only moan as he slammed in deep one last time, cock pulsing, thick ropes of cum flooding my ass again.

We collapsed — whimpering, ruined — his cock still buried deep, his hand tangled in my hair, my nipples sore from the brutal treatment.

I couldn’t move — sprawled on my stomach, face buried in the pillow, my body buzzing with soreness, emotion, filthy satisfaction.

Then I spotted it — my THC pen on the nightstand.

Perfect.

With a shaky hand, I grabbed it, took a long, slow hit — held it in as a slight burn hit my lungs. Another pull — the haze curling around my face, the tension finally melting off me.

What a perfect way to end his filthy love for using me like his own personal cum rag.

He rolled onto his side, eyes dark, raking over me — half in the ridiculous Harley Quinn costume, crop top sweat-slick to my skin, fishnets clinging to my thighs, hot pants twisted around one ankle.

“Jesus…” His hand slid down my spine, lingering low, brushing the raw, tender curve of my ass, spreading me just enough to look.

“You really took that… you okay?”

“My asshole may never be the same… but yeah. I’m excellent.”

“C’mon.” He slid off the bed, grabbing my wrist with that cocky smirk. “Shower time before you pass out.”

I let him pull me up — legs shaky, thighs sticky with sweat and cum — every step a reminder of how utterly destroyed I was.

The hot water felt good, his hands gentle as he soaped me up, but nothing could erase the deep, lingering ache between my cheeks.

By the time he dried me off and moved me back to bed, I was heavy, loose, exhausted.

He eased me onto my stomach, hand smoothing along my back as he sat beside me.

“You okay?” his voice softer now, threaded with real concern.

“My ass… is literally throbbing…” I admitted, burying my face into the pillow.

A quiet laugh rumbled from him, his fingers trailing lightly along my spine.

“Yeah… Did I overdo it?” he murmured.

“No… I could go again if you wanted.”

“Really?”

“Yeah.”

“Maybe in a little bit. I came so hard both times… I need recovery time.”

“Whenever you’re ready,” I muttered.

“Your asshole still sore?”

“What do you think?” I shot back.

I heard him pad into my bathroom. I didn’t move — too spent to lift my head, the ache radiating with every slow pulse.

He returned — small pop of a lid, faint medicinal scent drifting past me.

Before I could ask, his hands slid over my hips, careful, warm, parting my cheeks.

“Easy…” he whispered, fingertips tracing the swollen, tender skin.

I flinched at the first touch — a sting — but his hand stayed firm on my lower back, grounding me, soothing.

“This is gonna help.”

The burn faded instantly, replaced by a spreading numbness that eased the raw ache to something bearable. My body relaxed against the sheets, tension bleeding out.

“What is that…?” I mumbled.

“Just… something to help,” he said softly, rubbing it in slow circles. “Don’t stress… you’ll feel better shortly. Or until I come back in a couple hours.”

His lips brushed my temple as he pulled the blanket over me, tucking me in.

“Sleep,” he whispered. “I’ll be back in a couple hours.”

I didn’t know how long I’d been asleep. Everything hurt, in the filthiest way — my body sore, raw, completely used. But what finally dragged me back from sleep was behind me… and the thick, heavy weight of his cock resting right between my ass cheeks.

I barely stirred, too floaty to care — until his hips shifted, his cock grinding slowly between my cheeks, dragging over my swollen, tender asshole.

“You awake, sis?” His voice was low, dark, and filled with lust.

I let out a lazy, half-conscious whimper, my body still heavy, loose from earlier.

“Good…” His hand slid over my hip, gripping tight, spreading me open just enough for his cock to settle snug between my cheeks. “Been waiting to fuck my little sister’s tight ass again…”

I shivered, breath catching as he rocked his hips, his cock sliding over my hole, teasing me awake.

“Thought you were done…” I mumbled, voice raw, weak, gravely.

“Oh, sis…” he groaned, kissing the back of my shoulder as his cock ground down harder, his free hand grabbing the lube off the nightstand. “You know better than that. I told you I would be back in a couple hours… here I am… You were begging for me to come back.”

The slick sound of lube coating his cock filled the quiet room as he shifted behind me. His other hand slid under me, gripping my tit, squeezing, as he rocked forward — his cock pressing down, sliding lower.

“You’re gonna take it again…” he whispered, filthy, rough. “I’m not stopping until I fuck my little sister stupid.”

Before I could process it, he was flipping me onto my back, my legs falling open on instinct. His eyes roamed over me — flushed skin, sweaty, nipples hard from him rolling them through his fingers — a smirk pulling at his mouth.

“Fuck… look at you,” he muttered, stroking his cock over my stomach, teasing me. “Wrecked by your sibling… and ready for more.”

His hands grabbed my legs, lifting them, spreading me wide, pushing my thighs up until my knees were near my chest. His cock dragged down, the fat, slick head nudging against my still-swollen little asshole.

“You know what’s coming…” His eyes were dark, voice low, breath hot against my ear. “Say it.”

“I’m… your little sister…” I whispered, breathless, the filthy thrill making my pulse race. “And you’re gonna… stick it in my ass again…”

“Yes, yes, I am,” he growled.

He shoved forward — slow, brutal — the fat head of his cock stretching my little hole all over again, pushing inside with steady pressure, splitting me wide.

“F-fuck—” I gasped, back arching, my legs trembling as he pushed his cock into me.

“Such a good girl… look at you,” he groaned, staring down as my tight, abused asshole swallowed his cock. “Takin’ your brother’s cock… just like you were made for it.”

Once he was buried to his balls, he grabbed my legs, pushing them higher, settling my ankles over his broad shoulders — folding me in half, completely exposed, helpless.

“Just like this…” His hips drew back, cock dragging slow through my stretched hole — before he slammed in, hard and deep.

I cried out, fingers digging into the sheets, my body jerking with the force of his thrust.

“Love fucking my sister’s little ass,” he groaned, pace building, brutal, relentless. “Love watching you take every inch… love knowing no one else gets to ruin you like I do.”

His cock slammed deep with every thrust, his hips grinding against my ass, his balls slapping down, the sound of skin on skin filthy, raw.

“You’re mine, aren’t you?” His hand slid around my throat, fingers tightening just enough to make me dizzy. “My little sister… my cock sleeve… say it.”

I whimpered, eyes rolling back as his cock pounded into my ass, the pressure, the stretch overwhelming.

“I’m… I’m yours,” I gasped, voice breaking. “Your little sister… your slut… your sex toy…”

“Damn right you are.” His grip on my throat eased just enough for me to breathe, his other hand gripping my thigh, pushing my legs even higher, my ankles now shoved next to my head — completely folded, completely exposed for him to plow.

He leaned in, his cock burying impossibly deep in my ass, his chest pressing to my thighs, breath hot against my ear.

“Such a filthy little thing…” he whispered, hips snapping forward, hard and fast. “Bet you dreamed about this, didn’t you? Your big brother… ruining your tight little asshole.”

I couldn’t speak — only moans and gasps left me as he fucked me, relentless, raw, his cock wrecking me from the inside out.

My legs trembled, pinned high, my ass stretched wide, the brutal pace stealing my breath, the ache melting into filthy, helpless pleasure.

“You love it,” he hissed, biting at my shoulder, his cock pounding deep. “Love being my little fucktoy… love knowing you’re just my sister and I still fuck you like this.”

My orgasm slammed into me without warning — body shaking, pussy dripping down as I clenched around him, my asshole fluttering helplessly around his cock.

“Look at you cum,” he groaned, not slowing for a...
