Mine is from a movie of the 1970's - Tobacco Roady. The hottest scene I have ever seen was a girl/girl/boy/girl scene held in a barn. Very hot action.
ok I got one!! My favorite porn is Pirates!! and there a tons of good scenes! But my favorite is The part where the married woman is tied down in a chair and surrounded by a bunch of pirate men and this really hot woman goes down on her and she tries to object but changes her mind and gives in because it feels so good!! SO HOT!!
