It's not even quite clear whether the brother helped his sister, pleasured her, or taught her. Either way, she should be grateful to him after a fuck like that. It's funny to see how he uses both his phallus and her toys to develop his sister's anal hole. It's bright and exciting, and you can see the details that are so valuable in a process like this. I wonder what he will turn her on with next time.
The chick isn't bad, but I like the mom a lot better! I love juicy chicks like that. And when she laid down with her thighs spread, I definitely wouldn't have rested until I'd have put her in the front! At least they could make a film with elements of lesbian games, since there are already two naked women quite interested in sex in the frame anyway. And the man together would have been better served, anyway it would have been interesting!
Fuck me like that
