The voyeur, hidden behind the closet door, watches as his little sister, new to her sexuality, discovers her brother's long, thick cock. She timidly strokes it, her tiny hand barely able to wrap around its girth. Her eyes meet the voyeur's in the mirror, and she blushes, but doesn't stop. She takes it in her mouth, her inexpert sucking driving the voyeur to the brink. The room fills with the sounds of their mutual pleasure, the voyeur's heavy breathing and the sister's soft moans echoing in the confined space.
