In the dim light of their shared room, Brazilian siblings Ana and Lucas find themselves alone, their parents out for the night. Ana, curious and horny, starts touching herself, her fingers dancing over her wet pussy. Lucas, pretending not to notice, strokes his hardening cock under the sheets. Their games escalate as they watch each other, Ana pushing her toy deeper inside her, Lucas gripping his shaft tightly. When Ana whispers, "I wonder what your cock feels like," Lucas can't hold back. He crosses the room, pushing her down on the bed, his thick cock sliding into her tight pussy. They fuck hard, their moans filling the room, until they collapse, spent and satisfied.
