Looking for a Quicksand Sinking Story

[Eido]

I know I asked this question here before, and got an answer, but a forum crash or reset has erased both.

The story goes like this: A woman restrains herself on a beach, playing a dangerous game with herself. Her bonds are not locked initially, and she tosses a weight into a pool of quicksand. The weight is attached to her via a cable and a piercing. She is blindfolded and nipple clamped, and so is pulled toward the quicksand. Her restraints will lock if she jostles them the wrong way.

Of course, she missteps and the cuffs on her wrists lock and she can't release herself and is therefore doomed to die in the mire.

A man is secretly filming the entire scene, excited beyond measure, naturally.

In one version of the story, the ending is grim as he just stands by and watches. In another version, he rescues her. The rescue version was on Gromet's Plaza, I thought, but numerous searches have been unsuccessful.

Your help greatly appreciated.

I suppose that would be this excellent story: https://www.selfbound.net/storiessz/tale_of_possession.html
One of my favorites as well.

Thank you! Aside from getting to read it again, now my restless mind can start spinning about something else

I'm pretty sure I have both versions. Are you still looking for the version where she does not get rescued?

Yes, I'd like to have both versions. Thank you!
