In the close quarters of their shared home, Michelle and her stepbrother cannot escape the taboo allure of their bodies. One evening, they find themselves alone, their parents away. The siblings, both virgin and haunted by religious guilt, turn to each other for comfort. They begin to touch, their semi-clothed forms pressed together in the cramped closet. Michelle gently pushes her brother's massive cock inside her, both of them trembling as they cross the line of no return. Their father's voice echoes in their minds, but their bodies betray them, lubricating the shafts as they rub their tight, untouched vaginas along the hard cocks. They fall into a frenzy, their lust consuming them, only to collapse into post-coital remorse amidst smeared juices and spent fluids, praying for absolution from their taboo lust sins.
