I would really, really like to see something like that
Actually reminds me of a request I had a while back,
Inspired by this Gilda hard vore story from a while back.
If I could write I would try but if any writer who likes it wants to pick it up they can, it could really be done by any character but I choose Gilda because the idea was a sort of an aftermath.
Standard vore story, anon gets eaten and digested.
And then he wakes up, could be anywhere near Gilda, but in my original idea he's in the toilet, maybe with Gilda's ass still above him.
After some panic from both anon and Gilda, they both realize anon is a ghost.
He decides to haunt Gilda's ass (literally it seems he can't go too far from it).
He has standard ghost abilities, can pass through stuff, become invisible, but Gilda can always see him and he can't pass through her but she can't hurt him no matter what she does.
For the next couple of days/weeks he makes her life hell for eating him.
This ends when she snaps and bites him and realizes he tastes just as delicious as when he was alive.
He gets eaten again, she taunts him for a bit, he realizes he can't die again so he intends to wait it out.
Maybe a bit at the end where whenever Ghost!Anon shows up again Gilda eats him again.>td;lr
Anon gets eaten, becomes ghost, still gets eaten
