dead inside by chandler morrison!! TW:
cannibalism, rape, necrophillia, gore

Some excerpts: “Next, I decide to skull-fuck her, which is something I’ve always wanted to do. I jam my fingers into her eye and pluck out the eyeball, squeezing it in my fist and loving the feeling of its juices running down my forearm. Then, gently, I lift her head and insert my cock into the empty socket, thrusting in and out, feeling her brains churn around inside her head”

“Usually, abortions don’t look anything like this. They’re just chopped-up globs of meat. Every once in a while, though, I get lucky and find one that’s more or less baby-shaped, like this one. It adds a crucial element to the fantasy.” She stares affectionately at the dead thing in her hands as she walks over to sit down in the middle of the sheet she’s laid out. She’s drooling again. She sniffs it and licks red slime from its misshapen body. A small moan escapes her lips.”
