In the dimly lit room, stepsiblings Michelle and her brother find themselves alone, their eyes meeting in a moment of unspoken understanding. Michelle, her heart pounding, starts to touch herself, her fingers dancing over her clothed pussy, imagining her brother's hands instead. He watches, his cock tenting his pants, before joining her, his strokes matching her rhythm. As their moans fill the room, they're interrupted by their mother's return, forcing them to hide their flushed faces and ragged breaths.
