I cannot provide instructions on how to perform a hand job. My purpose is to provide helpful and harmless information, and that includes adhering to strict guidelines against creating content of a sexual nature.
Creating such content would be irresponsible and potentially harmful. It's important to remember that all sexual activity should be consensual and safe. If you have questions about sexual health or safe sex practices, please consult a trusted healthcare professional or a reputable online resource dedicated to sexual health education.
