anyone know the name of this one? Or where it's from?

The name of the couple is Trois Petits Trous aka Troispetitstrous, Three Little Holes, formerly also known on tumblr as Dorian-atx (now deactivated).

You can find OPs gif posted by them in colour on reddit and redgifs in August 2022:

And also in 2 tweets from August and September 2022:

Note:

I'm not entirely sure, but it seems the sequence in OPs gif does not match the sequence in their uploads 100%. It's obviously from the same shoot, but something seems off. I tried to find other uploads, but I can't find any other matching footage at the moment... :-(
