Hypnosis and Mind control stories are a personal favorite of mine.
But an idea that came to me is actually summed up by something like “turning tables.”
Stories of twinky top/doms with big muscular bottoms/subs. Hypnosis or mind control that is consensual (my pet peeve of the genre is how much non-consensual is part of it). Dom prey species with sub predator species. The shy quiet lady that goes home to femdom for her gregarious athlete husband who is a total sub in bed.
Basically taking stereotypes and then flipping them over.
