Awillingstudent, you are correct. I never expect facesitting. I simply describe it as an interest and leave it up to the Domme to decide activities in a session. I would certainly never expect naked facesitting in a session. Thanks for pointing out this ambiguity in my original post.

Still interested in hearing if anyone has had interest/experience in permutations 2,3 or 4. Or do they just not exist?
