Confined in a closet, siblings Michelle and her brother maintain a semblance of modesty, but their bodies betray them. Michelle's fingers trace her curves, her brother's cock stiffens against his will. Guilt-ridden, they try to resist, but Michelle's lubrication coats his cock as she grinds against him. Their father's voice echoes, "Don't move!" yet they can't halt their descent into taboo lust. Their bodies join, Michelle's tight pussy enveloping her brother's cock, until they collapse in post-coital shame, praying for forgiveness.
