Nice, now that filled in a lot of background information. Like Saki genetically being a hermaphrodite.

Wow Saki's pretty disgusting. Manipulating her close friends just for sexual gratification. Wonder if it'll bite her in the ass. Probably won't since futas always get off scott free

@Lufdne: Oh shit, it is. On page 11 of that gallery, her friend says her name, "Yuzuki", is cool. And her nickname is "Chino-chan". Meanwhile, the name on the research log in this story (page 12 of this gallery) is "I*chino*se Yuzuki". So that's completely confirmed. Very nice catch.
