There are very few true 'femdom slave for life' stories that are publicly available in a non - inappropriate way. In some role - playing communities, people might create fictional narratives around this concept. For instance, a story could be about a man who, due to a debt of honor, becomes a life - long servant to a noblewoman. He must follow her every command, and his life is dedicated to serving her needs. But again, this is all in the realm of consensual role - playing and storytelling, and any real - life equivalent would need to be based on the utmost respect for all parties involved.
I don't have specific 'femdom slave for life' stories to share directly. However, in general, such stories might involve a power dynamic where one submits to a dominant female figure for a long - term or life - long commitment in a consensual, often BDSM - related context. But this is a very niche and complex area that should be based on strict ethical and consensual relationships.
