The guy is lucky with his sister - she is a nipple. She's ready to open her mouth for him to stick it in her. Apparently she serves him regularly, because he no longer feels affection for her, but fucks her like a street whore - rough and bold. However, she seems to like this treatment.
Despite the fact that this is a call girl, already on the first minute of the video you can see that her slit is already wet. That is to say, she clearly liked the client in appearance. Even his shallow dick didn't embarrass her and she didn't give any sign that there was anything wrong with it. I especially liked the fact that at the end she took it all in her mouth (which is not peculiar to girls of this profession).
