Forbidden Flames: A Sibling’s Secret Desire

Written By

Forbidden Ink

In the quiet suburbs of Chicago, where the American dream painted perfect pictures of family life, lived the Thompson siblings. Alex, a 22-year-old college dropout turned mechanic, with his rugged build and dark hair, and his sister Mia, 20, a budding artist with curves that turned heads—slender yet voluptuous, her skin like porcelain, breasts full and firm with pale pink areolas, her intimate folds plump and tender, her passage tight and warm. They were close, perhaps too close, sharing a house after their parents’ divorce. But beneath the surface simmered a taboo attraction, fueled by stolen glances and unspoken desires.

One stormy evening, as thunder rumbled outside, Mia lounged in her room, her body illuminated by the flickering candlelight. She wore a thin silk nightgown that clung to her ample breasts, the fabric whispering against her smooth skin. Alex knocked, entering with a bottle of wine, his eyes lingering on her form. ‘Sis, you look… incredible,’ he murmured, his voice husky. Mia blushed, her heart racing. ‘Alex, we shouldn’t… but I can’t stop thinking about you.’

Their first encounter began with tentative touches. Alex’s hands roamed her body, feeling the warmth of her skin under his palms. He cupped her breasts, thumbs circling the shallow pink areolas, eliciting soft moans from her lips. The air filled with the scent of her arousal, a musky sweetness mingling with the rain outside. Mia’s fingers traced his chest, down to his hardening cock, veins pulsing under her touch, the purple-red head glistening with pre-cum.

They moved to the bed, Alex positioning himself behind her for their initial union. Foreplay was slow; he kissed her neck, tasting the salty tang of her skin, while his fingers explored her slick folds, parting the plump labia to tease her swollen clit. Mia gasped, her breaths coming in shallow pants, the wet sounds of his fingers sliding in and out echoing softly. ‘Oh God, Alex, I need you inside me,’ she whispered, the taboo words hanging heavy.

As he entered her from behind, the sensation was exquisite. His thick shaft, rigid and throbbing, pushed slowly into her tight, wet heat. Inch by inch, her inner walls enveloped him, slick and yielding, the friction sending sparks through both. He felt her contractions, like velvet gloves squeezing him, as he bottomed out, his tip pressing against her cervix in a deep, intimate nudge that blurred the lines of penetration—almost as if entering her very core.

The rhythm built gradually, from gentle thrusts to fervent pounding, the slap of flesh against flesh mixing with her whimpers and his grunts. Her scent intensified, a heady mix of sweat and feminine musk. As climax approached, Mia’s breathing quickened, her passage fluttering with pre-orgasmic spasms, love juices flowing copiously. Then the peak hit: her body shuddered violently, walls clamping down like a vise, milking him in rhythmic contractions, a gush of fluid soaking them both. She screamed his name, muscles tensing then melting into bliss. In the afterglow, her depths pulsed gently around him, their mingled essences warm and sticky, a profound satisfaction washing over them like waves.

They lay entwined, whispering forbidden confessions. ‘That was wrong, but so right,’ Mia sighed, her body still humming. After a tender interlude, desire reignited. This time, facing each other in missionary position on the bed, Alex above her. Foreplay resumed with deep kisses, tongues dancing, tasting the lingering salt of sweat. He suckled her breasts, the firm globes heaving, nipples hardening under his lips.

Entering her again, the merge was tender yet intense. His cock slid into her welcoming warmth, her labia parting like petals, inner folds gripping him tightly. The thrusts were slow at first, building to a passionate cadence, each plunge hitting her depths, that illusory fusion where he felt buried in her womb. Sounds of wet suction and breathless moans filled the room, scents of arousal and semen blending intoxicatingly.

High tide came with her legs wrapped around him. Pre-climax built with ragged breaths, her walls quivering, fluids drenching them. Orgasm exploded: tremors racked her frame, contractions fierce and unrelenting, squeezing him like a fist, her cries echoing as ecstasy peaked, then ebbed into soft pulses, their bodies slick and united in post-coital haze.

Exhausted but insatiable, they moved to the bathroom for a shower, steam rising around them. Under the hot water, beads cascaded over Mia’s curves, highlighting her glistening skin. Alex pressed her against the tiled wall from behind, their third union igniting. Foreplay involved soapy hands gliding over bodies, fingers probing, lips tasting the clean yet aroused flavors.

Thrusting into her standing, the insertion was swift, her tight channel enveloping him amid the water’s rush. The rhythm was urgent, hips slamming, the slap amplified by wetness. He felt every ridge of her inner walls, the deep penetration mimicking entry into her sanctum. Scents of soap mixed with their natural aromas, tastes of water-kissed skin.

Climax built rapidly: her breaths hitched, spasms starting, juices mingling with shower spray. The pinnacle was cataclysmic—shaking limbs, vise-like grips, a torrent of release, screams drowned by water, followed by lingering throbs and a deep, soulful connection.

As the water cooled, they dried off, collapsing into bed. Their forbidden bond, once a secret flame, now burned brightly, a taboo love defying norms.
