In the silent casa, boredom gives way to curiosity as XiaoYing and Juan find themselves alone. XiaoYing, horny and unfulfilled, begins to pleasure herself, her moans echoing through the empty halls. Juan, drawn to her room, watches, his cock tenting his pants. They clash, words heated, but the air's thick with lust. Later, they meet again, naked, XiaoYing's eyes locked on Juan's hard cock. She wants it, needs it, but a noise outside forces them to pause, their desires unresolved.
