Let's Find Some Recommendations

It's like the title says, give me a list of unpopular stories, more specifically those from the smut category and the most depraved thing you've read. I've already read Adam's Rib, Tentacle Recipe, Your Wish is My Command, Obey Me, Glory Hole Games, and The Beast Must Die. I've been trying to acquire a list of the more disliked within the smut genre, I prefer them to be yoais, but do surprise me and give me them from any as I'm sure there's more I haven't found. I'll give all of em a read. Scare the hell out of me manago.
