Absolutely love this concept. A person, lacking any control over the process themselves, is lowered onto an object for insertion with their weight and gravity doing all the work. The extent of her lack of control here is icing on the cake, but the whole "no one is doing this, it's just happening" aspect just really does it for me (thinking on it just now, it's probably an evolution from a fucking machine fetish). Bump post insertions are fantastic for this, but I feel like I can count on one hand the number of times I've seen a rack or other such mechanism set up for the process like it is here. Want more.

Also this needs a fetish term. The closest I've seen to it is the uncommonly labeled 'hanging insertion' but this is more specific than that. Personally, I call it 'gravity assist' insertions.
