Young and curious, these two amateurs find themselves alone on a quiet afternoon, their boredom leading them to explore each other's bodies. The girl's fingers dance over her wetness as she tries to keep quiet, but her stepbrother catches her mid-act. Tensions rise, but so does desire. They decide to masturbate openly in front of each other, the girl's eyes widening at the sight of her brother's thick, straight cock. As they're about to cross the line, an unexpected visitor forces them to abort their intimate encounter.
