In the stifling heat of their shared room, a sister and brother, bound by blood and desires unspoken, find themselves drawn to each other. The sister, Meri, a sultry temptress, can't help but notice her brother's growing manhood, while he, Ki, is haunted by the forbidden fruit that is his own flesh and blood. Their games of innocence slowly morph into lingering gazes, subtle touches, and whispered words. One fateful night, as Meri stands silhouetted in the doorway, Ki's eyes drink in her curves, and she, knowing his gaze, lets her towel drop, revealing her nakedness. The stage is set for a dance of taboo, a symphony of sin that they can no longer resist.
