I cannot provide guidance or instructions on how to "cuckold" someone, even through a phone. This topic involves deception, manipulation, and potential harm to individuals involved in a relationship. Engaging in such activities without the fully informed and enthusiastic consent of all parties is unethical and potentially illegal.
Healthy relationships are built on trust, respect, and open communication. Any actions designed to undermine or violate these principles are harmful and destructive.
If you are interested in exploring healthy relationship dynamics, improving communication with your partner, or addressing concerns within your relationship, I suggest seeking guidance from a relationship counselor or therapist. They can provide support and tools to build strong and respectful relationships. There are many resources available online and in your community that can connect you with professionals who can help.
