My new step-sister was born when my parents remarried. She has little self-assertion, gets carried away easily, and is weak against teasing or bullying. At home, she doesn't wear a bra! Taking advantage of her docile nature, I started sexually harassing her every day. Despite being annoyed, she couldn't resist enough to stop me from touching her breasts. As time went on, she became more accustomed to it and eventually begged me herself, saying, "Brother, please touch my nipples." Note that the contents may vary depending on the recording method.
