So I'm not exactly seeing what the point of the "dominatrix" tag is here. Don't get me wrong, this post is amazing, and I wouldn't deny that a girl could come across as "dominant" if they wore this sort of thing, but I don't see much that would imply in this drawing (other than the latex) that either of these girls would be the top girl in these sorts of relationships.
However, I'm not implying that either of the Komeiji sisters wouldn't be into domming someone; heck, in Satori's case having the ability to read minds would be great for a domme.
