"I Became a Futanari Yuri" (or alternatively: "Futanari Yuri Transformation")

Shikishima Risa, who had become mutually in love with her childhood friend Kashinami Maho, but one day when she wakes up—exactly as the title suggests! It's yuri. This work is a derivative fanfiction of "Something Deeper Than Like, Deeper Than Hate (R-18)" (http://ncode.syosetu.com/n6353dh/) serialized in Midnight Novels. I think it's good if you've read that, but I think it's fine to read that one after reading this one too.
