The pulsating bass from the main house was a distant throb here, in the private glass-walled conservatory. Adunbi’s hand rested on the small of his wife Quivina’s back, her sleek black dress cool under his palm. They had come to see, to be seen, to perhaps play. He hadn’t expected to see her.
Osa stood alone by a potted orange tree, a silhouette against the city lights glittering beyond the glass. His sister. Two years younger, and a vision he had trained himself not to see. Tonight, that training shattered.
The conservatory’s ambient light sculpted her. She wore a simple, backless crimson dress that clung to a figure that was all generous, swaying curves. Her hips flared from a narrow waist, promising lush, heavy flesh beneath the fabric. The dress ended high on her thighs, showcasing legs that were long and powerfully shaped, tapering to delicate ankles. Her black hair, usually tied back, fell in loose waves over smooth, ebony-brown shoulders. When she turned, the neckline dipped, revealing the deep, valley between breasts that were firm and pert. Her ass, rounded and high, filled the red fabric perfectly, a ripe peach ready for tasting. Adunbi’s mouth went dry.
“Go talk to her, ” Quivina whispered, her voice a low purr in his ear. Her nails traced his spine. “She’s alone. I’ve seen you look. I’ve been looking.”
A knot of heat twisted in Adunbi’s gut. Quivina pushed him forward, a gentle, insistent pressure.
Osa turned as he approached. Her eyes, the same dark mahogany as his own, widened, then softened with a warmth that had nothing to do with family. “Adunbi. You’re here.”
“So are you.” His voice was rough.
Her gaze flicked over his shoulder to where Quivina lingered, watching with a small, knowing smile. Osa’s full lips curved. “Your wife is beautiful. She’s watching us.”
“She knows what she wants, ” Adunbi said, the words feeling dangerous and right.
Osa’s laugh was a soft, smoky thing. “And what is that?”
“To watch me fuck you, ” he said, the vulgarity hanging in the air between them, stripping away pretense. “To watch me breed you.”
A visible tremor ran through Osa’s frame. Her breasts rose with a sharp intake of air. She didn’t look away. “There’s a room. Down the hall. Keycard on the table.”
It was that simple. A shared, silent understanding, charged with years of forbidden curiosity. Quivina fell into step beside him, her hand finding his, squeezing once in silent command.
The room was dim, lit by a single lamp that cast long shadows. The door clicked shut, sealing them in a bubble of quiet tension.
Osa faced them, her back against a heavy mahogany desk. Without ceremony, she reached behind her back, found a zipper, and let the crimson dress pool at her feet. Adunbi’s brain stuttered.
She was naked. Her body was a masterpiece of voluptuous womanhood. Her breasts were elegant puffs, dark areolas and taut, pointed nipples. A soft, flat belly led down to the stunning delta of her sex. She was completely bare, waxed smooth, her pussy a pronounced, lean mound. Her labia were prominent and beautiful�longer inner lips, a dusky pink-brown, peeking enticingly from between the outer folds, slick and glistening already. Her pussy was wet for him.
“Fuck, ” Adunbi breathed, his own hands moving to his belt.
Quivina came up behind Osa, her hands sliding around to cup her heavy breasts, thumbs circling her nipples. “Look at her, Adu. Look at that perfect cunt. It’s begging for your cock. Our cock.”
Adunbi shoved his pants and boxers down. His cock sprang free, and Osa’s eyes dropped, her lips parting in a silent ‘O’.
It was a thick, heavy weapon. Long, easily over nine inches, and so thick his own fingers couldn’t meet around the shaft. The veins stood out in thick ropes under the skin, pulsing with his heartbeat. The head was a broad, smooth plum, flushed dark purple, a prominent ridge separating it from the shaft. Pre-cum already beaded at the slit, a clear promise.
“You’re going to stretch me, ” Osa whispered, not with fear, but with raw, hungry awe.
“Yes, ” was all he could manage.
Quivina guided Osa to bend over the desk, her lush ass rising into the air. The sight was devastating. Two full, round hemispheres, dimpled at the crease where thigh met cheek. Between them, her pink-brown pussy lips were swollen and parted, glistening with her arousal. Her asshole was a tight, darker brown pucker below, clenching in anticipation.
“Get behind her, ” Quivina instructed, her voice husky. “Fuck her just like that. Let me see you take her.”
Adunbi moved, his hands landing on the warm, smooth skin of Osa’s ass. He kneaded the heavy flesh, spreading her cheeks apart. Her pussy was right there, dripping. Her inner lips were puffed and dark, a deep pink flower already blooming for him.
He guided the broad, blunt head of his cock between her slick folds. He didn’t push. He just teased. He rubbed the sensitive crown up and down her soaked slit, tracing the length of her entrance, gathering her wetness, painting her lips with it. Each pass made her whimper, made her hips jerk back.
“Please, ” she gasped, pushing her ass back toward him. “Adunbi, please.”
“Not yet, ” he growled, his own control fraying. He focused on the head, pressing it gently against her opening, feeling her body resist, then yield to the pressure. He withdrew, then pressed again, a gentle, rhythmic nudge. On the third press, her body surrendered. The thick corona of his glans popped past her outer lips, sinking into the incredible, clutching heat of her entrance. He stopped, buried just the first thick inch.
A guttural moan tore from Osa’s throat. “Oh, god... it’s so much.”
He pulled back, her stretched ring clinging to him, then pressed again, sinking another impossible inch deeper. In. Out. Each withdrawal made a soft, wet shlup sound. Each penetration scooped more of her juices. He worked her open with a patient, relentless rhythm, his hands holding her hips steady. He was sheathed in her own slick heat, her channel pulsing around the invading thickness.
“Take it all, Osa, ” Quivina murmured, her hand stroking Osa’s back. “Take your brother’s big fucking cock. You can feel it, can’t you? Stretching your pretty little cunt so wide.”
Osa could only nod, her forehead pressed to the cool wood of the desk, her knuckles light where she gripped the edge. Adunbi felt her inner muscles flutter, a frantic, welcoming spasm as he finally, after an eternity of gentle stretching, seated himself to the hilt. His balls slapped against her clit, his groin pressed flush against the plump curves of her ass. He was fully inside her. The feeling was mind-breaking�tight, hot, silken pressure around his entire length.
He didn’t move for a long moment, letting her adjust, letting them both feel the profound, wrong, perfect fullness.
Then he began to fuck.
He started slow, long, deep withdrawals followed by hard, driving returns. The sound was obscenely wet, a rhythmic slap-squish-slap as his pelvis met her ass. Her cheeks jiggled with every impact, a mesmerizing ripple of flesh. He watched, enthralled, as his thick, veined shaft disappeared into her glistening pussy, her swollen lips stretched taut around the base.
“Fuck me, ” Osa chanted, her voice breaking. “Fuck me, Adu. Breed me. Fill my fucking pussy!”
Her words, her surrender, unleashed him. He gripped her hips, his fingers digging into soft flesh, and began to piston into her. His pace became brutal, relentless. The desk creaked. Osa’s moans became screams, muffled against the wood.
“Quivina, ” Osa sobbed. “I need... I can’t... touch me!”
Quivina’s hand snaked down from Osa’s back, her fingers finding the swollen nub of Osa’s clit, now easily accessible from her angle. She rubbed hard, fast circles in time with Adunbi’s pounding thrusts.
The change in Osa was instant. Her back arched sharply. Her internal muscles clamped down on Adunbi’s cock in a sudden, violent vice. A high, keening wail tore from her throat, completely unrestrained. Her orgasm ripped through her, a visible tsunami of sensation that made her entire body convulse. Her pussy milked him, rhythmic, pulsing contractions that squeezed his shaft from root to tip, demanding his own release.
It was too much. The pressure, the heat, the forbidden taboo of it, the sight of his wife’s hand working his sister’s clit. Adunbi felt the dam break.
He drove in one final, deep, grinding thrust, burying himself as deep as he could physically go. The head of his cock pressed against the deepest part of her, a soft, yielding resistance at the entrance to her womb.
He came.
It wasn’t a release; it was an eruption. Deep inside her, a hot, thick jet of cum blasted from him, coating her cervix. Another pulse followed, and another, a torrential flood of seed. He could feel it, a scalding, liquid weight filling her, flooding her channel, spurting with such force it felt like it was hitting the back wall of her womb itself. The pulses kept coming, a seemingly endless geyser of thick, white cum. He grunted, animalistic, his body locking up as he emptied everything he had into her clutching, welcoming heat.
Inside Osa, the world narrowed to a white-hot point of sensation. The initial scalding flood was a shock, then a spreading, profound warmth. It was more than a sensation; it was a claim. The thick, viscous fluid pooled deep within her, a heavy, living presence. She felt impossibly full, stretched wide by his cock, and now overflowing with his essence. Her womb, still fluttering from her own climax, seemed to draw on that warmth, pulling it deeper, accepting it. A primal, cellular knowledge settled in her belly: life. The frantic, microscopic soldiers were already swimming, a desperate race through the sudden, fertile ocean he’d created inside her.
Adunbi stayed buried inside her, his body slumped over hers, both of them slick with sweat and panting. His cock, still semi-hard and impossibly thick, remained lodged within her, a plug keeping his massive, hot load trapped inside her trembling channel.
Quivina leaned over, her lips close to Osa’s ear, her voice thick with satisfaction. “Feel that? Feel my husband’s cum filling up your tight little womb? It’s pooling inside you right now, sweet sister. So much of it. Do you feel it dripping deeper?”
Osa could only moan, a weak, overwhelmed sound of absolute surrender.
Quivina’s eyes met Adunbi’s over Osa’s heaving back. Her smile was triumphant, feral. “Don’t pull out. Not yet. You should stay right there, locked inside her. Let it all settle.” She trailed a finger down the sweat-slicked valley of Osa’s spine. “What do you think... should we get you on your back? Let me watch his cock slip out of that well-used pussy and see just how much of his seed you can’t keep in?”
