ASS worshipers...?...

Just outta curiosity...does anyone know of any girls who are legitimately/genuinely into having their asses worshipped...and into things like face sitting? I've seen a few providers who have obliged but im looking for a freak who loves having a guys face,tongue in their ass and are into smothering me with their cheeks. Im looking for a girl who will take charge and just sit on my face without any coaxing or me having to ask...I love 69 and the pussy always gets attention but I just looking for a beautiful ass in my face...I prefer older milf/cougar types and they're the ones who have actually been most accommodating but im open to recommendations
