I'm a very nurturing Domme and back in my pro-Domme days, some of my favorite sessions were of the mommy domme variety. I could see myself in somewhat of that role in a long-term FLR but I'm sure My version of Mommy Domme wouldn't jive with everyone's.

I get the impression that some subs want a Mommy who literally does everything for them, takes care of the bills, and treats him literally like a child (with no adult responsibilities). That wouldn't work for Me because I expect my man, whether submissive or not, to be self-sufficient in all the normal ways an adult should be, and to pay at least his share of the financial expenses. 50/50 at a minimum. But I would happily provide the nurturing and cooing and nursing and all of that. I'm naturally nurturing with my partners and I enjoy being suckled even with my vanilla partners.
