The first one sounds really familiar, and I must have read the second, but I can't place either of them. Maaaybe you could PM me the titles, so I can satisfy my curiosity without accidentally offending anyone?

I actually can't describe the fics that sucked me in despite myself - I tend to lose details really quickly, which is why I keep descriptive notes on my bookmarks, except the two fics that I recall being particularly scarring only have the notes 'Aaaagh holy fuck,' and 'Augh, murder,' and 'I cannot read this story again, it will kill me.' So, you know, I guess they're descriptive of something. Not really the plot.
