The extended trip felt like a gift from the universe—another full week of the house to ourselves, no parental interruptions, no need to hide the growing web of secrets. Karin and I had christened the bathroom again that morning, her riding me slow on the bathmat until I flooded her shaved pussy with another thick load, cum leaking out as she kissed me lazily. But even as I caught my breath, my mind wandered to Kaho—her playful teasing in the shower, that hot mouth teasing my cockhead, her fingers still phantom-wet around my shaft.
She'd been ramping it up all day. After her afternoon yoga session in the living room, she pranced around in skin-tight black leggings and a cropped sports bra, sweat glistening on her toned stomach and collarbones. The leggings clung obscenely, outlining every curve—especially the prominent camel toe between her thighs, the fabric molded to her plump shaved lips, a faint damp spot darkening the crotch from post-workout heat. Every time she bent to stretch or grab water, the material pulled tighter, seam pressing into her slit, making my cock twitch painfully.
By evening, the tension snapped. I was upstairs, heading for the bathroom to shower off the day's ache, when Kaho cornered me in the hallway—fresh from another "cool-down stretch," body still glowing with sweat, citrus scent sharp and invigorating mixed with the salty tang of exertion.
"Hey, big bro," she purred, backing me toward the bathroom door with that bubbly grin. "Need help washing up again?" Her blue eyes sparkled with mischief, hand trailing down my arm, nails grazing skin.
I didn't resist. The door clicked shut behind us, steam already lingering from earlier use, tiles warm underfoot. She pushed me against the counter playfully, then turned to the sink—bending forward to "splash water on her face," but really arching her back, ass tilting up invitingly. The leggings stretched taut over her cheeks, camel toe even more pronounced from behind: shaved pussy lips outlined perfectly, plump and separated by the seam digging in, a wet patch spreading as she wiggled subtly.
"Fuck, Kaho," I groaned, stepping close, hands gripping her hips. My cock hardened instantly, pressing thick against her ass through our clothes.
She glanced back over her shoulder, giggling breathy. "Like what you see? Been thinking about your big cock all day... after that shower taste."
I ground against her, feeling the heat of her shaved mound through the fabric. Hands roamed up under her cropped bra—palming her firm breasts, thumbs pinching those puffy pink nipples until they hardened further, eliciting a moan that echoed off the tiles. She pushed back, grinding her camel toe along my bulge, the friction maddening.
Clothes peeled away urgently—her bra first, breasts bouncing free, sweat-slick and perfect; leggings yanked down slowly, revealing inch by inch her flawless shaved pussy: mound swollen and bare, lips puffy pink and glistening with arousal, inner folds peeking slick and creamy, juices already trailing down her inner thighs from the tease.
My pants followed, cock springing out throbbing and veined, head slick with pre-cum. She wrapped her hand around it immediately—athletic grip pumping slow, twisting, thumb swirling the leaking tip. "So thick," she whispered filthily, "gonna stretch my little shaved pussy good."
She bent over the sink fully now, legs spread wide, ass up—mirror reflecting everything: her flushed face, hard nipples dangling, and that perfect bare slit from behind, lips parted invitingly, tight entrance clenching in anticipation, juices dripping visibly.
"Take me like this," she begged, reaching back to spread her cheeks wider, exposing her hole fully—pink, wet, virgin-tight despite her playfulness.
I positioned behind her, cockhead nudging her slick folds—hot, soaked, parting easily as I rubbed up and down her seam, coating myself in her creamy arousal. The mirror showed it all: my thick shaft sliding between her plump shaved lips, bumping her swollen clit until she whimpered.
Slow push in—inch by torturous inch, her walls velvet-hot and gripping, fluttering around my thickness as I stretched her open. She was tighter than Karin, athletic muscles clenching deliberately, sucking me deeper until I bottomed out, base pressed flush to her smooth mound.
"God, yes—fuck your sister's pussy," she moaned, eyes locked on the mirror reflection—watching my cock disappear into her shaved heat, her lips stretched taut around me.
I started slow, rhythmic thrusts—pulling out to the tip, watching her juices coat my shaft creamy white, then sliding back in deep, balls slapping gently against her clit. The mirror multiplied the taboo: her breasts swaying with each pump, face contorting in pleasure, my hands gripping her hips as I claimed her.
Faster now, pace building—wet slaps echoing loud in the tiled room, her moans bouncing off walls, bubbly giggles turning to desperate cries. "Harder... fill me like you fill Karin—know you do, saw the stains on the mat."
The confession spurred me—thrusts pounding deeper, angle hitting her spot, her shaved pussy squirting little gushes around my cock with every plunge. She rubbed her clit frantically, fingers slick, body trembling.
"Gonna cum—on my brother's cock—yes!"
She shattered, walls clamping vise-like, milking me in pulsing waves, juices flooding down my balls, dripping to the floor.
I followed seconds later—burying to the hilt, cock swelling as I erupted. "Take it all," I growled.
"Cum inside—fill me up!" she demanded, pushing back hard, ass grinding against me.
Hot ropes pulsed deep into her shaved heat, flooding her tight walls, creampie overflowing creamy thick around my base, leaking down her thighs in rivulets as I ground through the aftershocks.
We stayed locked, breathing ragged, mirror fogging from our heat. My cock softened slowly inside her, cum plugging her hole until I pulled out with a wet pop—her pussy gaping slightly, shaved lips glazed and dripping my load in thick strands.
She scooped some on her fingers, tasting it with a wicked grin. "Tastes like forbidden fun," she whispered, turning to kiss me—tongue sharing the salty mix, citrus and sex on her lips.
The bathroom echoed with our shared secret now—Kaho claimed, another sister creampied. But her knowing smile hinted the game was far from over.
Karin's turn to react was coming—and the steam was only getting thicker.
