Under the watchful eyes of their stern father, two innocent sisters, Vídeo and Deo, are put through their final test of purity. Clad in modest attire, they must resist the temptation of the naked, erect penises placed before them. Yet, as they slowly mount the hardness, their untouched vaginas begin to lubricate, betraying their burgeoning desires. The sisters struggle, their religious upbringing clashing with their awakening lust. The room fills with the scent of their arousal, as they teeter on the edge of sin and salvation.
