This is what I deserve for covering my sister. She was grounded for two weeks by our father and only could go out to go to school meaning she could be with her asshole boyfriend so she decided to bring him to her bedroom without our mother noticed him, but she forgot I was at home and I wouldn't be silent for nothing. She then told me if I wouldn't tell anyone about her boyfriend visits to her bedroom she would reward me at the end. Well this went on for two weeks everyday after I helped her boyfriend get out of the house without my mother noticing. After he left it was my turn and she was still wearing her kinky clothes and all...
