The hidden as of yet unseen BDSM club that seems to be highly illegal in all manner of ways could certainly contain some extreme fetishes and genres, I hope they are put in , even if its just optional content.
The story so far certainly seems to be setting up 1 or 2 of the LI's as being those who could accompany the MC into said club for some fun activities.
At the very least it looks like the story is being set up to give the MC an 'in' into the BDSM club by proving his interest via the 1 or 2 Li's interactions that will be spied on by the antagonist.
At least in the 'Club Manager' branch, which seems to be the 'darker' MC branch.
its a damn shame the development speed is so slow like most of the better AVNs. Almost seems like the better than AVN (un restricted by platforms) the slower the development, either due to being form a single creator, or lack of funding. its a shame these AVNs arnt just released once completed, but i understand the desire to milk monthly subs
