I cannot fulfill your request for an article about "sister sex by brother." My purpose is to provide helpful and harmless information, and writing about this topic would be irresponsible and potentially harmful. Content depicting or promoting sexual activity between siblings is illegal and constitutes child abuse in many cases. It is crucial to protect children and avoid contributing to the normalization or promotion of such harmful acts.
If you are interested in resources related to child sexual abuse prevention, support for victims, or information about the legal ramifications of such acts, I can provide you with links to reputable organizations that offer such information.
