When the pious siblings find themselves in a confined space, their religious constraints crumble. In the dim light, Michelle's eyes widen as she sees her brother's massive, erect cock straining against his pants. Unable to resist, she reaches out, tentatively touching the hard length, feeling it pulse with life. Her brother, equally entranced, slides his hand up her thigh, finding her wet and ready. They move slowly, their bodies pressed together, as their father's voice fades away. Michelle sinks down on her brother's cock, feeling it stretch her tight pussy as she falls into a rhythm of pleasure, her moans muffled against his chest.
