I believe this was done by some other artist on Deviantart. The first three in this gallery were removed because he wanted people not to just think of it as fap material.
Well, this was interesting, and to think the maid hypnotize the madam, and possession her, then have her old body remodeled, and transfer the madam soul into that body, to become sister or some sort, and went to the pub and have a couple of drinks with twin sister and have hynotize them so they can posses them and be real sisters...well, seems like the cycle would never end...
Anyway, this was interesting and looking forward for more!!!
Miku_Miku_Miku is right. I remember the exact same thing about the artist removing the most of the pages from DeviantArt for that reason. That must've been back in 2011 or so. I never thought I'd see these again, so thanks for sharing.
