Just remembered this one today, but I can't rememeber the title or author or details.
It's about a girl who turns herself into (disguises herself as) a mannequin (sexdoll?) to get revenge on this other woman (guy?).
It ends badly for her.
Any recommendations are welcome. Thank you.
It doesn't ring a bell but there isn't much here to jog my memory, Can you give me any more details, even if you are not 100% sure of them?
