I'm pretty sure it is finished as the end is the same as Depraved Awakening which is that you have to choose ONE woman with who you will spend your life and it would be complicated to add one more chapter since each woman's ending goes into a completely different direction.
I ended with Chandra & Aby by the way because they are the most open-minded and are into involving other girls into our sexual activities even if the other women are not as open-minded and some of them even left the city in the end.
