That sister was a whore, but a real whore. Her father rescued her from a well-known brothel and she now lived with them. But a woman like that is not satisfied with just one cock, so that day she wanted to try her brother's cock. Before she knew it she was spreading her legs showing off her huge young pussy and waiting for him to put it in her. She missed a young, hard cock like his, so as soon as he put it in her face showed what she was feeling at that moment. The whore was very excited, she didn't treat him like a client or a stepson, she simply limited herself to enjoying that boy.
