@W1slicer: There are two or three pages where Kai meets an alternate rule-63 version of himself, and the two of them have a threesome with Lisa. It is debatable if that does qualify or not for "gender change" since the ACTUAL Kai does not change genders. It even almost comes withing a reasonable distance of the rule of presence, with 14 pages out of 391. What does NOT pass rule of presence is all the dickgirl-related tags because there are exactly 4 pages (about 1% of the gallery) of Virya literally and explicitly turning her vag inside out (perks of being a shapechanging demon), but feel free to argue with the masses of dickgirl lovers that they REALLY should downvote all those tags...
