Asian brother finds his sister masturbating

She had left school early and in the family room there was no one around, so she was encouraged to do it, her friends had told her all about it, the way to do it and the feeling that would invade her, so she did it. Without worrying about who would hear her. So without haste she began, her inexperienced hands soon found the necessary rhythm and the pleasure soon came to her. When she finished scared she looked at her brother watching her from the entrance, the worst thing was that he had a penis in his hands and was ready to continue what he had started, all of course with her help.
