Saving people, hunting things: the family business. Modern AU: the Nies are hit by a demon's death curse, which is NOT fuck or die - it's fuck AND die, a kind of reverse cultivation curse that's usually directed against cultivation partners, destroying their golden cores little by little every time they fuck. NOT a clever curse to use against brothers! ...except that the curse comes with a chaser: its targets share blisteringly horny sex dreams every night, as a way of encouraging them to go ahead and give in to the whole fuck-and-die schtick. Awkward. So it makes sense to search for a cure to the curse, right? Especially since the cure might actually help stabilise Mingjue's golden core. Obviously they have no intention of actually boning once they've got rid of the whole fuck-and-die curse... (...for the life of me I can't remember who suggested a Fuck AND Die trope on Twitter many weeks ago - evidently it has been living rent free in the back of my head ever since, though, and so here we have some Niecest.)

He wouldn’t know how to explain in any way that would make sense. Sometimes a monster fucks me in my dreams, and it leaves bruises. Sometimes I think I like it too much. That would definitely go over well.
