For the great site: girlsdoporn there is one girl on there named "Kelley"--busty brunette--and she absolutely lubes up the dude's cock with thick, white girl cream. It was like she hadn't been laid in awhile and her vag just milked his cock. He was even wearing a condom. It happened during the doggy part of the vid and the guy even motioned for the cameraman to come over and have a look. It was a blizzard of vag cream back there!
