The flesh fiend was a monster you were told about as a child, so you would be forced to keep yourself pretty by your mother. Since she made you fucking terrified of mutilation. What you didn't expect was for it to be real.

but it was. In your room. At your bed. Staring at you like he either wanted to rip your guts out, or rearrange your guts through sex. you watched the monster at the end of your bed... who knew what it could do if you let your eyes slip for just a moment
