In the dim light of their shared childhood bedroom, siblings Luis and Maria find themselves alone and horny. Maria, her curiosity piqued by a revealing magazine, tentatively suggests they explore each other's bodies. Luis, his cock already hard, agrees. He watches hungrily as Maria strips, revealing her perfect, round ass. She bends over, allowing him to tease her tight, virgin asshole with his fingers before pushing his thick dick inside. Maria gasps, feeling every inch as Luis slowly fucks her, their moans filling the room.
