For me it's probably quite obvious with my username but I like sissy play and puppy play as my 2 major fetishes as well as femdom which is the basis of most fantasies of mine. Then throwing in whatever else I feel like that day into the mix like pegging, wax play, pretend impregnation, pretend neutering, medical scenes (I have a "femdom vet clinic" scenario I like to fantasize about a lot), etc.
