Not sure why, but this game seems to be a bait of sort, since the "Sex" that is in the game are almost nonexistent, or atleast no actual sex going on.
Sure that some of the monsters and beast can sex the player, but they never cum, so all you can do is end the sex scene and get nothing interesting out of it (cum-inflation as the game imply it has in the game), so in other words there is no cum ending, but just a repeated loop with no ending.
There is also a bad lack of logic in how you seduce a sexable target, seeing that the only thing i can do to trigger it, is if i have sex on defeat enabled.
Even if you had a tamed beast to sex with, you still end up playing a loop sequence with no actual cum ending.
I played this about 4-5 months ago, and its still this crappy
