For that matter, I'd rather have her in a 69 position, it'd be more interesting for both of us! By the way, she did a good job on the cock, too. Probably imagined herself as a cowgirl, and her shoes as spurs, which she used to ride the stallion! When she laid down on her side, her shoes disappeared, so the ride was over? Apparently the movie was filmed in several stages, and we naively believe that the male is so hardy and can fuck a lady for a long time and not cum!
Girls got excited while riding stallions, so it's not surprising that when they saw those guys they jumped on them. Well, their chosen pose is exactly what I pointed out in the previous sentence. It has always been a mystery why so many girls love horses, actually this video partially answers this question.
Who can do it like that?
