Cramped in the closet, the siblings' religious upbringing fades as they succumb to primal urges. Michelle, trembling, guides her brother's thick cock to her tight opening, gasping as he pushes in. Their father's voice echoes in their minds, but they're lost in sensation - Michelle's wetness coating his cock, his hand cupping her breast, her nails digging into his back. They move in sync, their bodies slapping together, the closet walls amplifying their moans. Collapsing, they pant, their sweat and juices mingling, their taboo liaison sealed with a shared, guilty smile.
