It seems that it was a scene of a dark-skinned girl peeing an absolute gusher, from a peeing-outdoors video, specifically "beer fest #467." A user on thisvid has reposted it, but it is privated. Here is a screenshot and a link to the private video.

She pushes out a great amount

I suggest you to try some ad blocking extension such as AdGuard to avoid those invasive ads/riskwares

Great find!
She probably peed at least 1400ml+
Should have turned off the shower head, her stream would've been enough to take a shower

Yes I have the one I think you mean. I'll post it here shortly.

There’s another version of this clip around where she does show her face and it’s significantly longer. It might have been posted here recently

Lara CumKitten Huge Measure Piss
 

German women take some of the most amazing and sexiest pisses. She's nice and tall too, just like Daynia. Any man who passes up the chance to be showered by Lara's or Daynia's pee is simply missing out on one of life's greater pleasures.

but unfortunately a complete fake with 3 cuts in the video
