Uncle and Aunt teach Niece About Sex

I’m looking for a specific video. A girl goes to stay at her aunt and uncle’s house. That night, she wakes up to the sound of the two of them fucking. They notice her watching and invite her to join and teach her about sex. I think the original tag I remember from it was “keeping it in the family”. The aunt was fairly busty, and I think the niece might have had ponytails. Any help is welcome! Thanks!
