That was one thing I had in mind, but what about any of the monster girls in any wet dreams, like slime girls?
Also, can there be gender options for the human?

we are not going to do gender options for the human, as there is only one artist and that would add a significant amount of work which I don't have the time for, also the lore of succubi is their specific need for male essence, which would clash with those choosing a transgendered option as well as cis female (especially since I wouldn't want someone who wants to identify as female to constantly be reminded they are biologically male as that is what succubi go after.
As for dreams, they are all skippable if people aren't into the girl or type of content, so we probably will be adding a futa and/or femboy one!
