Stiles
By definition, a fantasy is something a person imagines and usually if one is curious about something, they try to imagine themselves in the scenario to try to work out that curiosity. So you might not call them that, but I'm still going to and there's nothing wrong with having them.
Why, is it really kinky? I can get into kinky... I'm open-minded. If you want to try something, Stiles, tell me. We can try it.
