What's the source of this video of a woman being fucked with her feet in the air?

I've seen this on Twitter/X a bunch of times, but it's always filled with bot comments. This is the longest version I've found. Reverse image search has always just led me back to different X bots reposting this video. I found this Chinese site also trying to solve it:

Could be from a JAV, but probably from some MyFans/Fantia content? It might not even be Japanese.

There's also another version floating around, same video with a red banner saying 足ピン (legs stretched out).

This is the longest video I've found on X:

Here's a couple more examples with a lot of comments/views (mostly spam):

Here's one from March of this year that has a link to a Fantia page in the comments (need Japanese VPN to open Fantia links):

Fantia page:

However it's pretty usual for these Fantia spam accounts to post unrelated videos, so it's hard to determine whether this is the source (as you can find older X posts with this video) and there's even AI generated manga panels based on it lol:
