Amara Tanith

Thorin is furious and obsessed with Thranduil, who is unaware of the obsession. Thorin wants to punish and own Thranduil. He wants to hurt Thranduil. However, Thorin knows that elves die if raped, so even though he wants nothing more than to exact vengeance out of Thranduil's hide, he is careful with the king when he finally gets him. Indeed, he is more concerned with this than Thranduil would be as Thorin has no idea what the line is for an elf. He's terrified of losing the king now that he has him.

-Bonus if Thranduil is a little scared/wary of Thorin, and Thorin has to earn a measure of his trust so that Thranduil will consent (but it's still a coerced union).
-Extra Bonus is Thorin misinterprets some of Thranduil's signals (like he grabs Thranduil's hair real hard, causing Thranduil to gasp, which Thorin thinks is from pain so he backs off, etc.).
-Extra Extra Bonus if Thorin fell in love with Thranduil way back when, had his heart broken when Thranduil didn't help his people, and all of his anger towards elves is just a shield to protect his heart, and the worry over death-by-rape is just Thorin's excuse to be nice to someone he feels he should hate but actually loves. Thranduil is completely unaware that Thorin feels these things towards him.

Would love if this was NOT dick!Thranduil. Also, would love if this became a happy ending but writer's choice.

The sheer volume and complexity of consent issues in this prompt have completely destroyed me. This is going on my to-fill list.

Ditto what that other comment said. (I believe s/he actually did write a fill, but I did not like it.)
