"Duko" is the cryptic title of a taboo tale dripping with forbidden lust. A brother and sister, bound by blood and burdened with religious guilt, find solace in each other's arms. In the confines of their shared bedroom, they engage in a dance of denial and desire, their bodies yearning for what their minds deem sinful. They touch, they taste, they teeter on the edge of climax, only to pull back, haunted by the ghosts of their upbringing.
