The evening sky bruised purple as a summer storm rolled in unexpectedly, thunder rumbling low like a warning. I'd spent the day in a haze of frustration, cock aching every time I caught sight of Karin around the house—her in tiny shorts that hugged her ass, bending over to pick something up, or stretching with that nightshirt riding high again. The glimpses of her shaved pussy haunted me, slick and smooth in my mind, making it impossible to focus.
Then the lights flickered once, twice, and died. The whole house plunged into darkness, the hum of electricity cutting out with a final sigh. Power outage. Great. I fumbled for my phone flashlight downstairs, but the signal was crap—no updates on when it'd be back.
Upstairs, a soft glow emanated from the bathroom door—cracked open as always, inviting. The only window in there was a large skylight, letting in the dim, stormy twilight, and Karin had lit a few candles on the counter. Their flames danced, casting warm, flickering shadows on the tiles.
I heard her moving inside, the soft scrape of something against skin. Curiosity—and that relentless throb in my pants—drew me closer. "Karin? You okay in there?"
Her voice floated out, calm and almost amused. "Yeah, come in if you want. It's the only room with any real light right now."
I pushed the door open wider, stepping into the humid warmth. The air was thick with steam from a recent shower, laced heavily with that peach scent, now mixed with something sharper—the faint, clean smell of shaving cream. Karin was seated on the edge of the bathtub, one leg propped up on the rim, completely naked from the waist down. Her nightshirt was bunched up around her hips, exposing everything.
Fuck. My breath stalled in my chest.
She held a razor in one hand, a can of cream in the other, casually lathering her calf. Her pussy was right there, fully on display—plump lips shaved baby-smooth, the mound glowing softly in the candlelight, not a hint of stubble. The outer folds were flushed pink, parting slightly as she shifted, revealing the glistening inner petals and the tight little entrance I'd fantasized about burying my cock in.
The storm outside growled louder, rain starting to patter against the skylight, amplifying the intimacy of the small room. Candles flickered, making shadows play over her skin—highlighting the curve of her thighs, the way droplets of water still clung to her from the shower.
"You've never seen a girl do this, have you?" she asked softly, eyes meeting mine with a mix of shyness and bold curiosity. She didn't cover up. Instead, she spread the cream up her shin in slow, deliberate strokes, the razor gliding after, leaving perfectly smooth skin in its wake.
I shook my head, throat dry, stepping closer without thinking. My pajama pants tented obscenely now, cock straining hard and thick against the fabric, a wet spot forming where pre-cum leaked steadily. "No," I managed, voice rough. "Never like this."
She smiled, biting her lip, and switched legs—propping the other up higher, knees bent wide. This angle exposed her even more: her shaved pussy lips spreading open naturally, the inner folds slick and shiny, clit peeking out swollen and needy. I could see every detail—the way her hole clenched faintly, a bead of arousal gathering at the entrance, threatening to drip.
The razor moved higher now, to her thighs, careful strokes inching toward that sacred center. "It feels amazing after," she murmured, voice breathy, eyes locked on mine. "So sensitive... every touch is electric."
She finished her legs, rinsing the razor in the sink, then—god—reached for the cream again. Without hesitation, she spread a dollop directly over her mound, fingers rubbing it in slow circles over her smooth lips. The motion parted them wider, cream mixing with her natural wetness, making obscene slick sounds in the quiet room. Her clit throbbed visibly as she "accidentally" brushed it, hips twitching, a soft whimper escaping her lips.
I was transfixed, rooted to the spot, cock pulsing painfully. The peach-scented steam wrapped around us, thick and heady, mixed with the musky tang of her arousal filling the air. Rain hammered the skylight now, thunder vibrating through the walls, matching the pounding in my chest.
She picked up the razor again, tilting her hips up for better access. Stroke by careful stroke, she shaved what little regrowth there was—though it was already flawless—gliding over her outer lips, pulling them gently to the side for the inner curves. The razor whispered against her skin, exposing more of that silky perfection, her pussy glistening cleaner, wetter with every pass.
Finished, she rinsed off under the faucet—cold water trickling over her mound, making her gasp and arch, lips swelling fuller from the shock. Then she turned to me, eyes dark with heat. "Come feel," she whispered. "See how smooth it is."
My hand trembled as I stepped forward, kneeling between her spread legs. She guided my fingers—warm, lotion-slick—to her thigh first, then higher. Skin like velvet, flawless. Then to her mound—god, it was unreal. Hot, baby-soft, not a single prickle. I traced the curve, thumb brushing her plump outer lips, feeling them yield softly, slick with arousal.
Lower, she pressed my fingers between her folds—wet heat coating me instantly, her inner walls fluttering as I grazed her entrance. "Touch it all," she breathed, voice shaking now. "Feel how bare I am for you."
I did—exploring every inch, circling her throbbing clit, dipping just the tip of my finger into her tight, dripping hole. She moaned softly, hips rocking into my hand, pussy clenching greedily around the intrusion.
My cock was leaking rivers now, straining desperately. She noticed, reaching out to palm me through my pants—fingers wrapping around the thick shaft, squeezing, stroking slowly up and down the length. Pre-cum soaked through, her hand gliding slickly. "So hard for your sister's shaved pussy," she teased, voice filthy and sweet. "Want to fuck it, don't you?"
I groaned, thrusting into her grip, the friction maddening. She pumped me harder, thumb circling the head through the fabric, spreading the wetness.
But then she pulled back, legs closing slightly, hand withdrawing with a wicked smile. "Not yet," she whispered, eyes promising more as thunder crashed overhead. "Soon... but not tonight."
She stood, nightshirt falling back down, brushing past me—her slick thigh grazing my arm, peach and pussy scent clinging to her like sin.
I stayed on my knees in the candlelight, cock throbbing untouched, the taste of her on my fingers, the storm raging outside mirroring the one building inside us.
The power stayed out all night. But the real blackout was in my restraint—it was crumbling fast.
The storm hit just past midnight, violent and unrelenting—thunder cracking like gunfire, lightning flashing bright enough to light up my bedroom in stark white bursts. Rain lashed the windows in sheets, wind howling through the eaves. I'd been lying awake anyway, cock still half-hard from the evening's torment: the taste of Karin's slick pussy lingering on my fingers, the way her shaved lips had parted so eagerly under my touch. Sleep was impossible with that memory looping in my head.
Then came the soft knock at my door—hesitant, almost drowned out by the roar outside. "Bro? Are you awake?"
Karin. Her voice trembled, small and scared. I sat up instantly. "Yeah, come in."
The door creaked open, and she slipped inside, silhouetted by a flash of lightning. She was clutching a pillow to her chest, wearing that same pale pink nightshirt, soaked at the hem from running down the hall. Her auburn hair was loose and wild, damp from the humidity, strands clinging to her neck and cheeks. Bare legs gleaming, feet padding softly on the carpet as she crossed to my bed.
"I'm... scared of thunderstorms," she admitted, cheeks flushing even in the dim light. "Can I stay in here? Just for a bit?"
I nodded, throat tight, shifting to make room. But the air between us crackled hotter than the lightning outside. She crawled onto the bed, curling close—too close—her body heat radiating through the thin fabric, peach scent blooming fresh and intoxicating in the confined space.
We lay there in silence at first, the storm raging, but her breathing was quick, shallow. Every thunderboom made her flinch, pressing tighter against me—her breasts soft against my arm, thigh draping over mine. My cock hardened fully, throbbing against her leg, impossible to hide.
She felt it. Her hand brushed my hip "accidentally," then lower, fingers grazing the bulge. "You're... hard again," she whispered, voice husky, not scared anymore.
The next lightning flash illuminated her face—eyes dark with want, lips parted. I couldn't hold back. I turned toward her, cupping her cheek, and kissed her. Slow at first, testing—her mouth soft, yielding, tasting faintly of mint and peach lip balm. She moaned into it, small and needy, tongue shyly meeting mine.
But the bedroom felt wrong—too open, too risky, even empty. "Bathroom," I murmured against her lips, the word rough with need. "Now."
She nodded eagerly, and we stumbled out into the hall, her hand in mine, thunder masking our footsteps. The bathroom door was already ajar, steam from an earlier shower still lingering in the humid air, candles long extinguished but the skylight letting in stormy glows.
We tumbled inside, locking the door behind us this time—no interruptions. The fluffy bathmat was soft underfoot, tiles cool. Clothes peeled away in the humid heat—my shirt first, then pants, cock springing free thick and veined, head slick with pre-cum. Her nightshirt next, lifted over her head in one motion, revealing her fully: small, perky breasts with hard pink nipples, flat stomach, and that perfect shaved pussy—mound swollen, lips already parted and glistening with arousal.
She stared at my cock, eyes wide, biting her lip. "It's so big," she breathed, reaching out tentatively. Her small hand wrapped around the shaft—fingers barely meeting—skin hot and velvet-soft against my throbbing length. She stroked slowly, shyly at first, exploring the ridges, thumb circling the slick head, spreading pre-cum down the shaft in wet glides.
"It's wrong," she whispered, pumping me steadily now, grip tightening, "but it feels so good... touching my brother's cock." Her words were filthy-sweet, breath hitching as she watched her hand slide up and down, foreskin peeling back to expose the flushed crown.
I groaned, hips bucking into her fist, the slick sounds obscene in the tiled echo. My hands roamed her body—palming her breasts, pinching nipples until she whimpered, then down to her shaved heat. Fingers delved between her plump lips—soaked, dripping, inner folds silky and burning hot. I circled her clit, hard and throbbing, then dipped two fingers inside her tight entrance, walls clenching greedily, virgin-tight around the intrusion.
She stroked me faster, hand twisting on the upstroke, milking more pre-cum that dripped over her knuckles. "Want you inside me," she confessed, voice breaking on a moan as I curled my fingers deeper, thumb grinding her clit.
We sank to the fluffy bathmat together, her beneath me—legs spreading wide, knees bent, exposing her shaved pussy fully in the lightning flashes: lips puffy and pink, hole clenching eagerly, juices trailing down to her ass.
I positioned myself, cockhead nudging her entrance—hot, slick, resistance giving way inch by torturous inch. She was impossibly tight, walls fluttering around my thickness as I pushed in slow, deliberate—stretching her open, bottoming out with a groan as her shaved mound pressed flush against my base.
"Fuck, Karin... so tight," I rasped, holding still to let her adjust, feeling her pulse around me.
She wrapped her legs around my waist, heels digging into my back. "Move... please, bro... fuck your sister's pussy."
I did—slow thrusts at first, pulling out to the tip, watching her slick coat my shaft, then sliding back in deep. The bathmat cushioned us, her hips rising to meet me, wet slaps echoing with the rain. Faster now, rhythmic—her small breasts bouncing, nipples grazing my chest, peach-scented skin slick with sweat.
Her hand snaked between us, fingers rubbing her clit frantically as I pounded deeper, angle hitting that spot that made her cry out—muffled against my shoulder. "Gonna cum... on your cock... yes—"
She shattered first, pussy clamping down vise-like, milking me in pulsing waves, juices flooding around my shaft, dripping onto the mat.
I couldn't hold back. Thrusts erratic, burying to the hilt—cock swelling, balls tightening. "Inside," I growled. "Gonna cum inside you."
"Yes—fill me!" she begged, legs locking tighter, nails raking my back.
I erupted—hot ropes pulsing deep into her shaved heat, flooding her tight walls, creampie spilling out around my base as I ground against her, milking every drop. Her pussy fluttered, drawing it deeper, overflow creamy and thick trailing down her thighs.
We collapsed in afterglow, bodies tangled, storm softening to a steady rain. My cock softened inside her, cum leaking slowly as I pulled out with a wet sound—her pussy gaping slightly, shaved lips glazed and dripping my load.
She touched it wonderingly, fingers scooping the mess, bringing it to her lips for a taste. "Our secret," she whispered, kissing me softly, peach and sex on her tongue. "This bathroom... just ours."
The thunder faded, but the heat between us burned hotter than ever. The fall was complete—and there was no going back.
