Looking for an old Legolas fanfic

The story involved Legolas stuffing/weight gain/inflation/mpreg, the whole shebang, very R rated.

In the beginning Glorfindel had captured him, and later Elrond came along.

I can't remember the exact title but it was something like "The Dark Lord who would be King" - I'm not sure but I think it was posted on a LOTR forum or fanfiction website?

I used to be able to find it by googling some combination of ^these words + some phrases I remembered from the fic. I can't find it anymore so my guess is it was removed but I'm hoping someone might have saved it somewhere.

Here are some phrases I remember were in there: "plump puppy"(1000% sure of that one), "Legolas you [?], you ate an entire turkey". Also when Legolas was spooked he would yell like "aiiiiii" or something.

If I remember correctly it was dated from the early 2000s, like 2002 or 2003, and the author mentioned that the fic had won the "most creative" category for what I assume was a LOTR fanfiction contest.

The story was tagged with either "body expansion" or "belly expansion" (well, I don't think the website had a tagging system but that was a key term at the top of the fic).

Why do I want it? It was my first instance of encountering something that made me go "I am not alone" about my fetish. It also showed me the term "expansion" which allowed me to actually search for related things instead of wandering aimlessly. So even if it was absolutely bonkers, it has a special place in my heart.
