I might have to do that to see if I like how it's presented. Even going ambiguous, there's ways to make the bondage sexy, and that's more what I want anyway, even if it's just through text. :P
Then again, I suppose genetelia can't be mentioned so... Hm... Unless it just says 'chest' and / or 'Nethers,' which are ambiguous enough to let the reader determine what it is.
Oh, I guess the other question I had is: can you train the girls to become doms or is the only relationship you have with them being to tie them up?
EDIT: Oh you teasing little... :P That wasn't what I meant when I said I wanted the MC tied up. xD
