Every woman is just a walking rectum, born to be buttfucked as an anal sodomy cocksleeve and semen receptacle. This woman is no exception, and I would gladly use her dirt tube to masturbate my penis for a few hours. I would relish every wince in her face, every whimper and grunt from her mouth.
I have had some women who enjoyed it first off, first time. Other who never enjoyed it only put up with it and others who pretended to hate it but really loved it.
