Another tumblr site that might catch a specialized audience is Femdom Marriage
"Pictures and stories, you can imagine, that they are about married people. No leather, no latex, no dungeons."
It had 799 pages of photos when I wrote this, so it is certainly over 800 now.
As it states no dungeons, but foot worship, face sitting, spanking, anilingus, pegging, dom /sub roles
but possibly others you would give an avoiding pass.
All the photos posted come from this site.
