A Gravure Idol Big Step sister Tempts You in a Bikini

The sun hung high in the sultry summer sky, its rays beating down on the lush landscape as a gentle breeze rustled through the trees. Down by the pristine pool nestled within the sprawling estate, Natsumi lounged on a plush deck chair, her voluptuous body draped in a skimpy bikini that left little to the imagination. The luscious Asian beauty’s caramel skin glistened with a thin sheen of sweat, her ample breasts heaving with each shallow breath she took.

Natsumi was a renowned gravure idol, her image gracing the pages of numerous magazines and advertising campaigns across Japan. With her alluring good looks and a body to die for, it was no wonder that she had a massive following of devoted fans. But Natsumi had a secret; beneath her flawless public persona lay a naughty, seductive temptress just waiting for the right opportunity to unleash her true desires.

As if on cue, Natsumi’s brother, Ryoji, emerged from the estate’s backdoor, a flock of paper cranes in his hand. The die-hard anime enthusiast had been trying to craft the origami birds for hours, but his current attempts only resulted in crumpled pieces of papers at his feet. Ryoji was clueless about Natsumi’s sinful thoughts, and even less so about the raging boner currently straining against the confines of his loose-fitting swim trunks.

Sprawled out on the nearby lounger, Ryoji’s gaze drifted over to his sister’s delectable form. Natsumi had always been a sight to behold, but today, something felt different. Maybe it was the way her generous curves filled out her tiny bikini, or perhaps it was the unbridled lust burning in her eyes as she locked gazes with her younger brother. Whatever the reason, Ryoji found himself drawn in, unable to look away.

Natsumi lifted herself up and sauntered over to her perplexed brother, her hips swaying hypnotically with each purposeful step. The air between them thickened with unspoken desires as she loomed over his prone form, now reading his mind and realizing his building arousal for her. Her fingers traced along the strap of her top, teasingly pulling it down to reveal more creamy skin.

“Having some trouble with your little cranes, dear brother?” Natsumi purred, reaching down to snatch them from his unresisting hands. With a deft flick of her wrist, she sent them all flying into the turquoise water.

Ryoji’s eyes widened, his mouth agape as he stared up at his sister in shock. “Natsumi! Those took effort!”

The alluring idol smirked, her hand slipping behind his head to thread her fingers through his hair. “I’m far more interested in your… effort,” she whispered huskily, her tongue darting out to wet her full lips.

Unable to resist her charms, Ryoji reached up to drag her down into a searing kiss, his tongue delving deep into her mouth to tangle with hers. Natsumi moaned into the passion-fueled embrace, grinding her thick ass against his straining erection as she wrapped her voluptuous arms around his neck.

“Mmm, you feel so good,” Natsumi purred, her hips rolling sensually as she dry humped her brother. “I want you, Ryoji. I want that big, hard cock inside me.”

Equally aroused, Ryoji reached down to hesitantly cup her plentiful ass, kneading the supple flesh in his hands. Natsumi squeaked in delight, urging him on with sultry moans as his hands slipped lower and toyed with the tie of her bikini bottoms.

With a sharp tug, the flimsy fabric fell away, baring her sopping wet pussy to his hungry gaze. Natsumi wasted no time in shoving a hand down her brother’s trunks, grasping his throbbing length and stroking it rhythmically. Ryoji groaned, his hips bucking up into her touch as he cupped her heavy tits, now only barely contained by her top.

“I need you, Natsumi,” he growled, roughly yanking the cups of her bikini down to expose her hardened nipples. “I need to fuck you so hard.”

Natsumi whimpered, guiding him to the edge of the lounger before straddling his hips. Her dripping slit aligned perfectly with his thick cock, the swollen head nudging insistently at her entrance. With a wanton cry, she impaled herself on his shaft, her tight walls clenching greedily around his hard length as she sank down to the hilt.

The two siblings moved in perfect sync, hips undulating as they set a frantic pace. Natsumi’s bountiful breasts bounced with each forceful thrust, the soft mounds jiggling enticingly as she rode him with wild abandon. Ryoji gripped her wide hips, pushing her harder and harder onto his cock, his balls slapping against her succulent ass.

“Oh, fuck yes!” Natsumi shrieked, her hands fisting in his hair as ecstasy consumed her. “Pound my pussy, baby brother! Make me cum on your cock!”

Ryoji obliged eagerly, one hand dipping between their sweat-slick bodies to find her throbbing clit. He rubbed the sensitive nub in tight circles, feeling her cunt spasm around him as her climax approached. Natsumi moaned uncontrollably, her eyes rolling back in bliss as her pussy clenched like a vice around his pistoning shaft.

“I’m cumming!” the gravure idol wailed, her orgasm crashing over her like a tidal wave. Her juices gushed around his cock, soaking his groin as her body shuddered in pleasure. Ryoji snarled, his own release building with each continuation of their liaison.

Unable to hold back any longer, Ryoji pulled out of his sister, stroking his twitching cock furiously. Thick ropes of cum erupted from his tip, splattering across Natsumi’s face and heaving tits. She moaned, running her fingers through the warm seed, gathering it up to lick the spunk from her digits.
