The lusty big-tit stepsister couldn't resist her brother any longer. One day, she joined him in the shower, her massive breasts pressing against his back. She turned him around and kissed him deeply, her hands exploring his body. She dropped to her knees, sucking his cock until he was rock hard. Then, she bent over and made him fuck her from behind. The hot water poured over them as they fucked hard and fast. She moaned with pleasure, loving every moment of their taboo encounter.
