I don't think it is that uncommon. There was a Domme in Toronto called Chastity Goddess that played that way.....In a cage and teased from the start of the session until the last few minutes. I actually had a booking with her but cancelled when I discovered that she also insisted on having her subs blindfolded for the entire session, start to finish.

I certainly don't mind hoods or blindfolds for extended parts of a session but not 100% of the time. Being able to see the Domme and watching her select implements or make preparations for the next activity adds a lot to the anticipation for me.

I think she retired around the time Covid hit. Still lots of hits on a Google search but the links to her website are dead.
