Step-Sis's Forbidden Backyard Oil Massage

Alex returned from college and stepped out onto the patio to find his stepsister Mia stretched out on a lounge chair in the late-afternoon sun. She wore only a tiny, barely-there bikini that barely contained her sun-kissed curves, her skin already glistening with warm oil she had just finished rubbing into her shoulders and arms. The backyard was private, ringed by tall hedges and privacy fencing, and their parents were gone for the weekend, leaving the two of them alone for the first time in years. The air between them had always carried that low, unspoken crackle—stolen glances at family dinners, accidental brushes in the hallway that had lingered too lang—now that crackle was rising into flames as she looked up at him with heavy-lidded eyes.

“Need some help?” he asked, his voice already husky.

Mia bit her lip and nodded. She rolled onto her stomach, presenting her mostly bare back and the perfect roundness of her ass framed by the thin strings of her bikini bottom. Alex grabbed the bottle of warm coconut oil, warmed it between his palms, and began to rub it into her skin. His hands moved slowly, deliberately, first across her back, then lower, spreading the oil over the smooth curve of her ass. He let his fingers dip under the string, brushing the cleft between her cheeks, teasing the edges of her sexual heat. He rubbed her thighs next, spreading her legs wider than needed, brushing his knuckles against the thin fabric covering her pussy as he went. Her soft, breathy moans floated up as he continued, already pushing them both jarringly into the forbidden territory they had both avoided for years. He moved up again, sliding his hands along the sides of her torso, brushing the sides of her breasts where they spilled out from her tiny bikini top. She moaned louder now, pushing back against him slightly.

Mia turned over. She spread her legs wide, the small bikini bottom already damp between her legs, oil slickening her skin further. She looked straight at him, her eyes blazing with need.

“Touch me properly,” she begged.

Alex ripped the strings of her bikini bottom aside and slid two fingers between her wet folds. Her pussy was hot and slick, already ready for him. He circled her clit with his oil-slicked fingers, feeling her grow wetter under his touch. She moaned again, wildly, oil-covered thighs trembling. He pulled the small bikini top aside too, exposing her breasts, then leaned in to suck one nipple into his<|eos|>
