In the quiet of their home, two siblings, driven by boredom and curiosity, explore their bodies. The brother, hidden in the bathroom, grips his hard cock, his breath hitching as he imagines his sister's touch. In the next room, she lies on her bed, her fingers dancing over her slick pussy, her moans growing louder. Caught in the act, they argue, but later, they come together, their bodies aching with desire, their eyes locked on each other's intimate parts.
