imagining needy choso begging you to let him cum after edging him for hours :(
its just that he was being so naughty, teasing you and thinking he could get away with it .
but in the end you gave in and let him cum all over your hand, licking it up while looking him dead in the eye as he blushes acting like he wasnt being a whore for you just a minute ago :/
Thinking about some intertexts with Touhou and one nightmare one would be the setting of the roleplaying game The Esoterrorists, which is about fighting people who are trying to reintroduce the fear of the unknown into the world to make magic real.
A funnier one would be the works of Tim Powers, which are on a vaguely harmonic freakquency, but you can imagine some California Guy seeing Yukari in his dreams and waking up screaming in terror.
