Seeing people act like this is on the same level of grooming or rape or pedophilia really shows you how weak some of them are. The DM's are fuckin' weird, sure, but nothing in them signifies him attempting to groom him or anything like that.
Someone else in the thread said it best, this isn't much worse than those old, cringy roleplay DM's you'd see from furries.
I'm not a betting rat, but 5 tokens says that "Lady" Emily is into more depraved things and is just projecting, at least to some extent.
