Where can I find this video? Who are the two women?

Their names are Morgan aka Morgan Bingham (on the right), Natalie aka Natalie Bell, Nala, Nala Elle (in the middle), and Natalie's partner in real life on the left, Austin aka Austin Siebler, Tattedfitness.

OPs short gif was uploaded to reddit several times by the couple during last year, but she deleted almost all of her old posts since then. You can still find it posted by him here:

When you scroll back in Morgan's tweets, you can find a few pics with all 3 of them together - here are a few examples from July/August 2022:

When you scroll back in his tweets, you'll find out that they (most likely) shot the scene with Morgan in June 2022:

On reddit, there are a few more posts of them together:

Based on all the comments from all of them, the full video is available on their accounts on OnlyFans. Unfortunately, I can't find any leaks of this scene for "free" online... :-(
