truthfully it depends on the day! one day i might want someone around the same size as my foot, so they can really press their whole body in there and i get to feel everything. other times i might want less of a distraction so i'd prefer to make someone lint sized and i can get on with my day. i would also enjoy someone quite a bit bigger than me being helpless to worship me, some big fucking brute who carries me around because they don't want me to get my perfect feet dirty.

so really, every size is the perfect size! bonus points if i change yours to fit whatever mood i'm in.
