My comment:
I know this is specifically HORROR stories but still. As a person who LIKES kinky RP stuff (though not in TTRPG style roleplay), I just do not get how so many people think it's okay to just spring the stuff on someone without their knowledge or permission.
Getting dark or kinky in your game involves needing buy in from EVERY. SINGLE. PERSON. at the table. Ahead of time!
And using random people as your therapy is just the extra little poo cherry on top.
