Cornelia1I captures the raw, intimate moment of a curious teen sister and brother exploring their desires together. Alone in the house, they turn to self-pleasure, Michelle fingering her wetness and rubbing her curves while her stepbrother strokes his thick cock. Caught in the act, they argue, but soon their bodies betray them, leading to an open masturbation session. Michelle's eyes widen at the sight of his massive cock, and she fantasizes about its touch. Just as they're about to cross the line, an unexpected intrusion halts their forbidden encounter.
