Clothed but aroused, they rub against each other, Michelle's tight pussy lubricating her brother's cock. Their father's voice echoes, "You mustn't move!" but their bodies betray them. They fall into an all-consuming, shameful act, collapsing in a mess of spent fluids and post-coital remorse, praying for forgiveness from their taboo lust.
