Hidden away in their shared room, the siblings can't deny the electric chemistry between them. The brother, sprawled on his bed, strokes his rigid cock under the sheets, eyes locked on his sister as she changes. She catches his gaze, her heart pounding. Dropping her towel, she reveals her naked body, daring him to react. He can't resist, pushing back the covers to reveal his engorged length. She approaches, her eyes widening at the sight. Kneeling, she tentatively reaches out, her touch igniting a fire within him. He pulls her onto the bed, their bodies grinding together, lost in a world of their own.
