i read all these sadly

So basically all of them?

Murderer Llewellyn's enchanting dinner invitation (cute at first but shit goes down badly later..)

Just toxic:
Stalker's Game

Mostly smut plot, wtf stories:
PLACEBO: Let's Play (has prequel)
Good Hunter & Bad Prey
Profundis (has plot, but mostly just gang rape...)
Caste Heaven (plot, twisted game, highly recommend)
Abyss

Interesting stories, some with plot, that are kind of toxic or have some angst?(one sidedly or both, enemies to lovers, hate/distrust to love tropes) but get better character development later on. So probably more tame than ur looking for but just incase ur interested in that too then:
Checkmate(TAN)
Lost in the cloud
No Moral
Blind Play
Stranger (not really toxic, but bro has intense intrusive thoughts of killing him and is possessive with a bit of lashing out, which is interesting)

Probably wasn't what h were looking for but if you're interested, I hope that helped

thank u!!
