Which video did the intro snippet from 00:05 come from?

Wrong time..
The girl of the preview is Carolina Sweets (https://spyfam.com/video/horny-stepsis-gives-stepbro-a-hot-tub-hand-job)
The girl of the 00:05 is Ariana Marie (https://spyfam.com/video/step-sister-waits-for-parents-to-leave)

And the girl of the 00:06 (the blonde you mention below) is Aubrey Sinclair in Boyfriend Watches Girlfriend Fucking Her Step-Father (SpyFam)

As it appears, it was actually Boyfriend Watches Girlfriend Fucking Her Step-Father, featuring Aubrey Sinclair.

For reference, I was specifically asking about this scene: https://imgur.com/a/9BrYzZt

It is NOT Ariana Marie, unfortunately, and the linked video is NOT it. The lady in the 00:05 ~ 00:06 mark is clearly a BLONDE.@bURREN
