Images number 15 through 18, 20 through 23, 28 and 31, and 33 through 45 are not futanari, and it really bothers me when people toss that stuff into a category where it doesn't belong. If anything, that stuff should be classified as shemale.
33, as well as pretty much all the other 3d gifs here, are made by sircus. they have BALLS, which is why Major says they're technically not "futanari", but come on...
anyway, 48 is princess knight catue, 50 is Tsukiakari no Raspberry, and 47/49 MIGHT be "Alignment You! You!"
