The phrase is rather unclear. 'Slave' and'slut' are inappropriate and offensive terms. If we assume it means that your wife used stories in some way, perhaps she used stories as a form of entertainment, like reading stories to pass the time or using stories to teach something, like moral lessons to children.
The statement 'My slave slut wife used stories' is very difficult to make sense of as it contains offensive language. However, if we focus on the 'used stories' part, she could have used stories in many ways. For instance, she might have used them as a tool for self - expression. Maybe she was an avid writer and used stories to pour out her emotions, dreams, or ideas. Or perhaps she used stories as a means of connecting with others, sharing her cultural heritage or family traditions through the medium of stories. In a more general sense, stories can be used to inspire, educate, or simply to create a sense of community.
Well, without more context, it's hard to be precise. 'My wife used stories' could imply that she told stories. Maybe she was creative and made up stories for various reasons. It could be for family gatherings to amuse everyone, or she might have used stories as a way to communicate her own experiences or feelings in a more engaging way. But again, the use of 'slave' and'slut' is unacceptable and makes the original statement very hard to interpret in a positive or normal sense.
