Demons enter your world

One demon or a group of demons enter your world with the purpose of increasing sinful acts on Earth. The easiest way that they have found is by utilizing lust and maybe a bit of ****. Their current target: you.

Evil Dead

These demons can be the scarier Evil Dead type for example; a Deadite possesses your mom then uses her body to fuck you, or like in Devilman Crybaby how the demons morph the bodies of the possessed. I think this is a bit more unique and would like to see someone more skillful do it

Or it can be a more cliche succubus type demon
