Sister’s Nude Day

After our parents died within months of each other from the same fucking lung cancer that had been eating them alive for years, Sandra and I found ourselves stuck with the old house. The place was paid off, the market was shit, and neither of us had a job worth a damn or a partner who stuck around. So we moved back in together. Me, Tommy, thirty-two, going soft around the middle, thinning on top. Her, thirty-five, still built like the wet dream she always had been—long dark hair, full tits that strained every top she wore, wide hips, a tight ass that made jeans look illegal, and legs that went on forever.

The first few days were pure awkward. We unpacked, sorted the attic junk, drank cheap beer on the back porch looking out over the conservation land that butted right up against our property. No neighbors could see a goddamn thing back there. Thick trees, high fence, total privacy. Perfect for whatever the fuck we wanted.

It was National Nude Day when everything changed. I didn’t even know the day existed until Sandra announced it over coffee that morning, wearing nothing but one of Dad’s old button-down shirts that barely covered her ass.

“I’m celebrating,” she said, voice already low and teasing. “Getting naked. All day. You should too.”

I laughed it off at first. “You’re serious?”

“Dead serious, little brother. Freedom. No clothes. No bullshit. Just skin.”

She stood up, the shirt riding higher, and walked straight into her old bedroom. Door wide open. I followed like a dog in heat, already half-hard just from the idea.

She turned to face me in front of the full-length mirror, fingers working the buttons of the shirt one by one. Slow. Deliberate. Each button freed more of that creamy skin I used to jack off to as a teenager. The shirt slipped off her shoulders and pooled at her feet. Underneath she wore a simple white bra that barely contained her heavy tits and a pair of plain cotton panties that clung to the soft mound of her pussy.

“You’re staring,” she said, smiling at my reflection.

“Hard not to.”

“Then don’t. Watch. Enjoy the show.”

She reached back and unhooked the bra. The straps slid down her arms. The cups fell away. Her tits spilled free—full, heavy, with thick pink nipples already stiff. She cupped them, lifted them, rolled the nipples between her fingers while watching me in the mirror.

“Still like them?” she asked.

My cock was a steel rod in my jeans. “Fuck yes.”

She pinched both nipples hard enough to make herself gasp. “I used to catch you looking all the time. Down my shirts. Through the crack in the bathroom door. You thought you were so sneaky.”

“You knew?”

“Of course I knew. It turned me on. Knowing my little brother was beating his meat over my tits.”

She hooked her thumbs in the waistband of her panties and pushed them down. Slowly. Over the curve of her hips, down her thighs, until they dropped to the floor. She stepped out of them and stood completely naked. Thick dark hair trimmed into a neat landing strip above her plump pussy lips. The lips themselves were already glistening.

“National Nude Day,” she said softly. “No more hiding.”

I couldn’t speak. My mouth was dry. My cock throbbed so hard it hurt.

She walked toward me, tits swaying, and stopped inches away. The heat of her body hit me. The smell of her—clean skin, faint perfume, and the musky scent of her wet cunt.

“Your turn,” she whispered. “Clothes off.”

I stripped. Shirt, jeans, boxers. My cock sprang free, thick and veined, the head already leaking. Her eyes locked on it.

“Jesus, Tommy. You’ve grown.”

She reached out and wrapped her fingers around the shaft. Soft, warm, perfect. She stroked once, from base to tip, smearing the precum around the head with her thumb.

“You’re leaking already,” she murmured. “Horny little brother.”

“Sandy…”

“Shh. We’re celebrating.”

She dropped to her knees right there on the bedroom carpet. Both hands on my cock now—one stroking, the other cupping my balls. She leaned in and licked a long, wet stripe up the underside, from balls to tip. Then she opened her mouth and took me in.

Hot. Wet. Tight. Her tongue swirled around the head while she sucked, cheeks hollowing. She bobbed slowly at first, taking more and more until the head nudged the back of her throat. She gagged softly, spit dripping down my shaft and onto her chin, then pushed farther.

I groaned, hands in her hair. “Fuck, Sandy… your mouth…”

She pulled off with a wet pop, strings of spit connecting her lips to my cock. “You always wanted this. Admit it.”

“Yes. Fuck yes. I jacked off thinking about you sucking me for years.”

“Good boy.”

She took me back in, deeper this time, fucking her own throat on my cock. Her hands worked the base, twisting, stroking. Spit soaked my balls. The wet sounds filled the room—slurp, gag, suck. She looked up at me with watery eyes, mascara starting to run, and moaned around my shaft.

I lasted maybe two minutes before the pressure built too fast. “I’m gonna cum—”

She pulled off, stroked hard and fast, and aimed my cock at her tits. Thick ropes of cum erupted, splattering across her chest, coating her nipples, dripping down into her cleavage. She kept stroking until every last drop was milked out, then smeared the mess over her tits with both hands, rubbing it into her skin.

“Look at that,” she said, voice husky. “Brother’s cum all over sister’s tits.”

I was still hard. Never went soft. She noticed and grinned.

“Outdoor time.”

We walked naked through the house and out the back door into the private yard. Sun warm on our skin. Grass soft under our feet. She spread a blanket on the ground near the old oak tree and lay back, legs open, fingers already sliding through her wet folds.

“Come here and eat this pussy,” she ordered.

I dropped between her thighs. The scent of her hit me hard—sweet, tangy, pure sex. I licked a long stroke from asshole to clit, tasting her. She moaned and grabbed my hair, pulling me tighter. I sucked her clit into my mouth, flicked it with my tongue, then pushed two fingers inside her dripping cunt. She was soaked, walls gripping me as I curled my fingers against that spongy spot.

“Yes… right there… fuck, Tommy, finger-fuck your sister’s cunt…”

I added a third finger, stretching her, while my tongue worked her clit in tight circles. Her hips bucked. She ground against my face, coating my chin in her juices. I licked lower, tongue pushing into her hole, fucking her with it while my thumb rubbed her clit. Then lower still—I spread her ass cheeks and licked her tight little asshole. She cried out and pushed back against my tongue.

“Dirty fucking boy… licking your sister’s ass…”

I speared my tongue into her hole, tasting the musky heat while two fingers still pumped her pussy. She came hard, thighs clamping around my head, juices flooding my mouth. I drank every drop, licking her through the aftershocks until she pushed me away, panting.

“Cock. Now. Inside me.”

I climbed over her, lined up, and pushed in with one long thrust. Her cunt was scalding hot and dripping, gripping every inch. I bottomed out and stayed there, feeling her pulse around me.

“Fuck… you’re so tight…”

“Been a while,” she gasped. “Move. Fuck me.”

I started slow, long strokes that dragged every ridge of my cock against her walls. She wrapped her legs around my waist, heels digging into my ass, pulling me deeper. Her tits bounced with every thrust. I leaned down and sucked a nipple into my mouth, biting gently, then harder when she moaned louder.

“Harder. Pound your sister’s pussy.”

I gave her what she wanted. Hips slamming, balls smacking against her ass, the wet slap of skin on skin echoing in the quiet yard. She met every thrust, fucking back up at me. Her nails raked down my back. I flipped her onto all fours, grabbed her hips, and slammed back in. Deeper this angle. She pushed back, ass jiggling with every impact.

I spit on her asshole and rubbed my thumb over it, then pushed the tip in. She moaned and pushed back harder.

“Yes… finger my ass while you fuck me…”

I worked the thumb deeper, then replaced it with two fingers, stretching her while my cock pounded her cunt. She came again, screaming into the blanket, cunt milking me in tight waves. I held back, kept fucking her through it, fingers still buried in her ass.

When she could breathe again she looked over her shoulder, eyes wild. “Cum in me. Fill your sister’s cunt.”

That did it. I slammed deep, buried to the hilt, and erupted. Thick pulses of cum flooding her, overflowing around my cock and dripping down her thighs. I kept thrusting, working every drop inside her until I was spent.

We collapsed on the blanket, sweaty, sticky, breathing hard. My cock was still half-hard inside her. She clenched around me and laughed softly.

“Round two in the house. Shower first.”

The shower was pure filth. Hot water cascading over us. She soaped my cock, stroking it back to full hardness while I soaped her tits, pinching the nipples until they were bright red. She turned, braced her hands on the tile, and pushed her ass out.

“Fuck me again. Use my pussy like it’s yours.”

I slid back in easy—she was still dripping with my earlier load. The water made everything slicker. I fucked her hard against the wall, one hand around her throat, the other reaching around to rub her clit. She came with a choked cry, cunt spasming. I pulled out, spun her around, and pushed her to her knees. She took my cock straight into her throat, swallowing around it while water ran down her face. I fucked her mouth until I came again, shooting straight down her throat. She swallowed every drop, then licked me clean.

We dried off and moved to the living room. She pushed me onto the couch and climbed on, reverse cowgirl, sinking down onto my cock until I was buried. She rode me slow at first, letting me watch her ass bounce, the way her cunt stretched around my shaft, the creamy mix of our earlier cum coating everything. I reached around and played with her clit while she ground down. Then she sped up, slamming down hard, tits bouncing wildly when she leaned forward. I grabbed her hips and thrust up to meet her. She came again, squirting around my cock, soaking my balls and the couch cushion.

I flipped us so she was on her back on the couch. Legs over my shoulders. I folded her in half and pounded deep, watching her face contort with every thrust. Her tits were in my face; I sucked and bit the nipples while I fucked her. She reached down and rubbed her own clit in frantic circles.

“Breed me,” she gasped. “Cum deep. I want to feel it leaking out of me all day.”

I buried myself and unloaded for the third time, pulsing hard, flooding her already full cunt until it ran out in thick white streams. We stayed locked together, kissing for the first time—deep, messy, tongues fighting, tasting each other and the salt of sweat and cum.

The rest of the day was a blur of sex. Kitchen counter—I bent her over and ate her from behind until she came on my tongue, then fucked her standing up while she held onto the edge of the sink. Her old bedroom—missionary, slow and deep, staring into each other’s eyes while I ground against her clit. The hallway—she dropped to her knees mid-walk and sucked me until I painted her face and tits. Back outside at dusk—she rode me in a chair under the oak tree, grinding slow, whispering filthy things about how good it felt to finally take her brother’s cock, how she’d fantasized about this for years too, how she wanted me to fuck her every day from now on.
