With their father's commanding voice echoing in their minds, the siblings fight their urges, but their bodies betray them. Michelle's hand snakes out, wrapping around her brother's throbbing cock. He jerks, his hips bucking as she strokes him, her own pussy clenching with need. They're consumed by their lust, their bodies writhing together in the cramped space. Michelle pushes her brother's cock inside her, her tight pussy stretching to accommodate him. They fuck frantically, their moans stifled, until they collapse together, their bodies slick with sweat and sin.
