The sister is not shy with her brother - he has known and used her body for a long time. She often bailed him out while he didn't have a steady girlfriend. Now he has a girlfriend, but he enjoys pleasing his little sister. And he always comes only in her mouth - she loves the taste of sperm.
What a juicy sexy and passionate blonde caught. I wouldn't mind doing a whole hour of cunnilingus to such a girl myself, no matter what it costs my tongue. Her partner has not such a large device, which suggests that the girl obviously cares about him and she does not use him just for sex. Too bad the scene where he comes on her face was shown too little, I wanted to see what she would do next with the sperm.
