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.
Quality ass lady, nothing to say. And how the buttocks on the dick is working and really cool! That and I just love to fuck in a cradle position such assholes, and if the thin girl gets on my dick, too, do not refuse. But the real pleasure I get only when I grab my hands on the full thighs of a standing upright asshole lady and slowly pull her in the front or anus with pleasure. Of course it's better to do it anal!
