The parents called that afternoon—some work delay, trip extended another week. The news hit the house like a spark to dry tinder. Karin shot me a heated glance across the dinner table, her foot brushing my calf under the cover, promising more midnight visits. But it was Kaho who reacted loudest, bouncing in her chair with that infectious energy, blonde ponytail swinging. "More freedom! We should celebrate—movie night or something." Her blue eyes locked on mine, playful challenge gleaming.
By evening, the air hummed with possibility. I'd been edgy all day, cock twitching at every glimpse of Kaho in her post-run glow—sports bra clinging to her firm breasts, leggings molded to her ass and the subtle camel toe outlining her shaved mound. The memory of her shower show looped in my head: water streaming over that smooth, plump pussy, lips parting invitingly.
I headed upstairs for a late shower, needing to cool off—or jerk off in peace. But as I pushed the bathroom door open, steam was already thick, citrus-scented and fresh. The shower roared, glass door fogged but cracked open just enough.
Kaho's voice sang out over the water, cheerful and teasing. "Took you long enough, big bro. Get in here—we're saving water, remember?"
My heart slammed. There she was, visible through the gap: naked under the spray, athletic body glistening, blonde hair plastered wet down her back. Water cascaded over her perky breasts, nipples hard and puffy pink, trailing down her toned stomach to her shaved pussy—mound bare and swollen, lips plump and seamless, inner folds peeking slick as she shifted.
I stripped fast, cock already rock-hard and throbbing, springing free thick and veined, head flushed and leaking pre-cum. Stepping into the steaming enclosure, the hot water hit my skin like a shock, drumming loud on tile and bodies, amplifying every breath.
She turned to face me fully, grinning, not a hint of shyness. "About time," she giggled, grabbing the body wash—citrus explosion blooming sharp and invigorating in the humid air. Her hands lathered up, suds foaming white, then reached for my chest.
Her touch was electric—palms slick and warm, gliding over my pecs, thumbs circling my nipples until they hardened. Lower, over my abs, fingers tracing the V-line teasingly close to my cock. It bobbed eagerly, brushing her stomach, leaving a trail of pre-cum on her wet skin.
She laughed softly, bubbly and delighted, wrapping one soapy hand around my shaft. "Look at you—instant hard-on for your little sister." Her grip was firm, athletic strength pumping slow and deliberate, suds making it glide effortlessly from base to tip. Thumb swirled the head on every upstroke, spreading my leaking pre-cum into the foam, slick obscene sounds mixing with the water's roar.
"Fuck, Kaho," I groaned, hips thrusting into her fist instinctively. She giggled again, free hand lathering my balls—gentle squeezes, fingers rolling them as she stroked faster, twisting her wrist just right.
"Your turn," she purred, guiding my hands to her body wash. I soaped her up greedily—palms cupping her firm breasts, thumbs flicking those puffy nipples until she arched and moaned. Lower, over her tight ass, then front—fingers delving between her thighs.
Her shaved pussy was burning hot under the cool suds, lips silky smooth and parting easily for my touch. Plump outer folds yielded to my fingers, inner petals slick with arousal far beyond water—dripping creamy wetness that coated my digits as I traced her seam. Her clit throbbed hard under my thumb, swollen and sensitive; I circled it slow, then faster, matching her strokes on my cock.
She spread her legs wider, one foot propped on the bench, exposing everything: shaved mound gleaming, lips spread wide by my fingers, tight entrance clenching greedily as I dipped one inside—walls velvet-hot and fluttering, sucking me deeper.
Mutual rhythm built—her hand pumping my thick shaft relentlessly, slick with soap and pre-cum, foreskin peeling back fully on every stroke; my fingers plunging shallow into her soaked hole while thumb ground her clit. Water drummed around us, steam thick with citrus and the musky tang of her pussy juices mixing in.
Her breaths came in giggles turning to gasps, hips grinding into my hand. "Feels so good... big bro's fingers in my shaved pussy," she whispered filthily, voice echoing off tiles. She sped up on my cock, grip tightening, milking me toward the edge.
I added a second finger, stretching her gently, curling to hit that spot—her walls clamped down, juices flooding my palm. She whimpered, knees buckling slightly.
Then she sank lower, kneeling on the wet tile—water streaming over her back, ass tilted up. Her face level with my cock, blue eyes looking up wickedly. "Just a taste," she murmured, tongue flicking out to lap the head—salty pre-cum mixing with citrus soap on her lips. She swirled around the crown, then took me in—mouth hot and wet, lips stretching around my thickness as she bobbed shallow, sucking greedily, hand pumping the base.
The sight—my athletic sister on her knees, shaved pussy visible between her spread thighs from behind, lips glistening and dripping as she clenched from arousal—nearly undid me. Her tongue teased the underside, cheeks hollowing as she sucked harder.
But she pulled off with a pop, lips shiny with spit and pre-cum, standing slowly. "Not yet," she breathed, hand giving my cock one last slow stroke. "I want the real thing soon... your big cock inside me, filling me up."
She rinsed off quickly, body brushing mine teasingly—hard nipples grazing my chest, shaved mound bumping my throbbing erection. Then she stepped out, grabbing a towel but not covering fully—flashing that perfect bare pussy one more time, lips puffy and flushed from my fingers.
"Think about that," she winked over her shoulder, citrus-scented steam trailing her out.
I finished alone under the cooling water, fist pumping furiously to the echo of her giggles and the phantom heat of her mouth, cum erupting in thick ropes against the tile—wasted, when what I craved was burying deep in her shaved heat.
The game with Kaho was on—and the tension was delicious torture. Soon couldn't come fast enough.
