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 pickup didn't even have to strain much - this bitch was just waiting to get laid. With such boobs, the males themselves gather around her. She didn't even seem surprised she was getting hit on. What a bitch, I cum on her too!
