In the quiet suburban home where they grew up, Elena and her brother Marcus had always shared a bond deeper than most siblings. Now both in their mid-twenties, Elena at 25 and Marcus at 27, they found themselves alone for the first time in years after their parents’ sudden trip abroad. Elena’s body was a vision of allure: her figure curvaceous and graceful, skin like polished porcelain, breasts full and firm with pale pink areolas, her labia plump and tender, her vagina tight and warm with moisture. Marcus, tall and muscular, felt the forbidden pull as old memories resurfaced.
The evening began innocently enough, with wine and laughter in the living room. But as the night deepened, Elena’s eyes lingered on Marcus’s strong frame. ‘I’ve missed you, brother,’ she whispered, her voice laced with unspoken desire. He pulled her close, their lips meeting in a tentative kiss that ignited years of suppressed longing. The taste of her lips was sweet, like ripe fruit mixed with the salt of anticipation.
They moved to Elena’s old bedroom, the moon casting silvery light through the window, highlighting the curves of her body as she undressed. Marcus’s gaze traced the elegant lines of her hips, the swell of her breasts. He cupped them gently, feeling the warmth of her skin against his palms, the nipples hardening under his touch. ‘God, Elena, you’re so beautiful,’ he murmured, his voice husky with taboo excitement. She moaned softly, the sound vibrating through him.
Foreplay built slowly. Marcus kissed down her neck, inhaling the faint musk of her arousal mixed with her floral perfume. His fingers explored her thighs, parting her legs to reveal her plump labia, glistening with wetness. He teased her clit, swollen and sensitive, eliciting gasps that filled the room. Elena reached for him, stroking his erect cock—veins pulsing along its length, the purple-red head swollen and leaking pre-cum that tasted salty on her tongue as she licked it tentatively.
Positioning her on the bed from behind, Marcus aligned himself. The insertion was deliberate, his cock slowly parting her tender labia, sliding into the tight, wet heat of her vagina. He felt every inch: the friction of her inner walls, slick and folding around him, contracting slightly as he pushed deeper. ‘Oh, brother, you’re so big inside me,’ she gasped, the words heightening the forbidden thrill. He thrust rhythmically, the wet slapping sounds echoing, her moans growing louder with each collision against her cervix.
As climax approached, Elena’s breathing quickened, her vaginal walls beginning to spasm lightly, love juices flooding around him. The peak hit her like a wave: her body trembled violently, vagina contracting fiercely like a fist squeezing his cock, juices squirting in hot bursts. She screamed his name, muscles tensing then relaxing in waves of ecstasy. Marcus followed, his release filling her with warm seed, the mingled scents of sweat, musk, and semen thick in the air. In the afterglow, her vagina pulsed gently around him, their bodies sticky and warm, a soul-deep satisfaction binding them.
They lay entwined, whispers of ‘I love you, sister’ and tender kisses prolonging the intimacy. But desire reignited soon. Elena straddled him face-to-face, her full breasts bouncing as she lowered onto his renewed erection. The entry was smoother now, her wet folds enveloping him completely, inner wrinkles massaging his shaft. ‘Feel how deep you go, brother,’ she purred, grinding against him, the rhythm building from slow circles to frantic bounces.
Her clit rubbed against his pubic bone, sending sparks through her. The sounds of their union—wet squelches and flesh slapping—mixed with her breathy moans. He gripped her hips, thrusting up to meet her, hitting her cervix with each powerful stroke, the depth feeling like he was entering her very core. High tide built: her breaths ragged, walls fluttering, then exploding in climax—shudders wracking her frame, contractions milking him relentlessly, a gush of fluids soaking them both. She cried out in rapture, collapsing onto him as he erupted inside, the aftershocks leaving them in a haze of pulsing warmth and mingled essences.
Exhausted yet insatiable, they headed to the bathroom for a shower. Under the steaming water, droplets traced Elena’s curves like liquid silver in the dim light. Marcus pressed her against the tiled wall from behind, the cool surface contrasting her heated skin. His hands roamed her slick body, fingers dipping into her still-sensitive folds, drawing out whimpers.
‘One more time, sister,’ he growled, entering her again. The water amplified every sensation: his cock sliding effortlessly into her drenched vagina, the tight heat enhanced by the steam. Thrusts varied—slow and deep, then rapid and forceful—each one eliciting sloshing sounds and her escalating cries. The scent of soap mingled with their arousal, taste of water-kissed skin on his lips as he nibbled her neck.
Climax brewed fiercely: her body arching, breaths panting, vagina quivering in prelude. Then the storm: full-body convulsions, walls clamping down with vise-like force, a torrent of juices mixing with the shower spray. She wailed, ‘Yes, brother, fill me!’ as he climaxed, pumping deep, the union feeling transcendent. In the lingering pulses, they held each other, the water washing away evidence but not the bond.
As dawn approached, they returned to bed, wrapped in each other’s arms. The forbidden love had consumed them, but in its wake, a quiet acceptance settled. They knew this was their secret, a taboo flame that burned eternally.
