The house is quiet, the parents away. The step-sister, a naughty vixen, can't resist the temptation of her step-brother's thick, throbbing cock. She teases him, sucking him off in the hallway, her full lips sliding up and down his stiff shaft. He can't help but grab her hair, fucking her mouth with wild abandon. They move to the bedroom, her juicy ass bouncing as he pounds her from behind, her moans drowned out by the sound of their bodies slapping together.
