Cloistered in a tight space, Michelle and her brother struggle to maintain their religious virtues, their bodies pressed close, their breaths ragged. As Michelle's brother grows hard, the siblings grapple with their growing desire.

As they collapse, spent and guilt-ridden, they pray for forgiveness, their hearts pounding with the echoes of their taboo lust.
