In the dim light of the bedroom, Rosinha's 'buceta' glistens with anticipation, her brother's gaze locked onto her slick folds. He runs a finger along her slit, feeling her heat and wetness, before pressing it inside, making Rosinha gasp and buck against him. He adds another finger, stretching her, preparing her for his cock. He replaces his fingers with his cock, pushing in inch by inch, feeling Rosinha's tightness envelope him. He begins to move, slowly at first, then with increasing force, his balls slapping against her ass as he pounds into her, their bodies slick with sweat and Rosinha's juices. Rosinha's moans fill the room, her orgasm approaching as her brother's thrusts become more urgent, his cock swelling inside her before he spills his load into her waiting pussy.
