wtf i need holy water

i really need holy water or i should just die so there will be 1 less even though its futile

Setting kinda doesn't make sense, if there is a Demon King there should be some Hero opposing him, considering it's porn and the situation maybe some higher being or something could give a males sperm the power to kill the worms or something than he can repopulate so he would have a world wide harem and any kids he makes wouldn't have to worry about them
