This is a weird one. You get two alternative storylines because I really wanted to do the possession/mind control one, but that kind of content is not allowed by the TOS of Betterwaifu, so I essentially have duplicated many of the images to support an alternative "futanarization + super libido" situation, which works in there.
I think it was sad to just have one version on each site, so I am adding both in here. Enjoy!
