In non - erotic story settings, 'free use' might be associated with the concept of open access or unrestricted utilization. Consider a story about a public park where the benches are for free use. It simply means that people can sit on the benches as they like, without any sort of reservation system or charge. It's a term that emphasizes the lack of barriers to using a particular element within the story's world.
Well, in non - erotic stories, 'free use' can refer to the idea of being able to utilize or access something without limitations. Let's say there's a story about a library that has a 'free use' policy for its study rooms. This means anyone can use the study rooms without having to pay extra fees or jump through a lot of hoops. It's about freedom and availability within the setting of the story.
