hi Citor3,
instead of a suggestion, this is rather an game idea.
what if we can play this game or one of the future game like the “paranormal VR”
https://m.youtube.com/watch?v=0CmMyhZY7vY
that you start from exploring in a very creapy and hellish place.
and being huanted and hunted by a sexy demon or succubus.
by giving the players no power, and making the gaming environment horrifing, will make the game almost like a horror game.
the players goal is to find his way out of this hell or escape the nightmare.
but the main point is that the demon will haunt you.
leaving the players hopeless and powerless to the powerful sex demons.
scared but turned on at the same time, the more scared and turned on you get, the more powerful the demons will become.
and eventually the player either reach the goal by defeating the demon, or finds his way out, or he will be captured by the demon.
if the player is captured, than he will face an endless sexsual tourment. until the pleasure becomes too overbearing, and basicly being milked dry by the demon.
Thank you for taking your time reading this.
and I look forward to hear your thoughts on this.
