Locked away, the siblings surrender to their taboo desires, their semi-clothed bodies pressed together in the dark. The brother's cock strains against his pants, while his sister's untouched pussy throbs. They're haunted by religious guilt, their whispered prayers mingling with their ragged breaths. They can't resist any longer, their hands tentatively exploring each other's bodies. The sister guides her brother's cock to her entrance, gasping as she sinks down, her tight pussy stretching to accommodate his size. They move together, their bodies slick with sweat, their moans echoing in the closet. As they approach climax, they cling to each other, their bodies shuddering with forbidden pleasure.
