A verification video gone awry finds a devout sister and brother, cloistered together, unable to resist their mutual attraction. As they huddle close, the sexual tension builds, their bodies betraying their religious upbringing. The brother's cock tents his pants, while the sister's nipples harden against her modest dress. Their hands, seemingly of their own volition, begin to explore, seeking forbidden pleasure. They freeze at the sound of a parent's footsteps, but their desire is undeterred. They resume their exploration, their religious guilt replaced by a hunger for each other, until they're consumed by a passionate, taboo-laced encounter.
