In the hushed silence of the sacristy, Father Miguel listens to the whispered sins of his parishioners. Today, though, the sins are of the flesh, and the sinners are two nuns, Sister Lucia and Sister Clara. Their confessions grow increasingly explicit, their voices laced with desire. As they confess their lustful thoughts and secret touches, the priest's imagination runs wild, picturing their naked bodies entwined. The air grows thick with tension, their breaths coming in ragged gasps, as they struggle to maintain their vow of chastity.
