Looking for scenes that open up with a couple that are planning to have sex coming across another couple already in the act and they watch them fuck. A great example of this is BLACKED "My Girlfriends Hot Sister Cassidy Klein Loves BBC". Cassidy comes across Rob Piper giving it to a random brunette and she cant help but stare at him pounding her. Rob sees her, winks, blows her a kiss and then proceeds to hard dog the random brunette who exclaims "give it to me harder"... naturally Cassidy lifts her skirt and starts rubbing magic circles. Eventually Cassidy and Rob get together for a hot lusty interracial scene.
