Under the guise of religious piety, a devout father summons his two daughters to his study, instructing them to verify their purity in preparation for their arranged marriages. The girls, innocent yet curious, follow his orders, stripping down to their undergarments and presenting themselves for inspection. As the father examines their bodies, his own lust begins to stir, and he finds it increasingly difficult to maintain his composure. The girls, sensing his growing excitement, take matters into their own hands, using their newfound knowledge of the flesh to satisfy their father's hidden desires, ultimately leading to a forbidden, incestuous encounter that will forever change the dynamics of their family.
