A blonde lady gets anal fisted in the gym by another lady. They both meet on the gym and one begin to rub her hand all over the ass of the other. Then when the blonde lady bends over, the other lady slips a finger in her asshole. Then she slips in two fingers and fucks her with them.
Then she adds more fingers as she fucks her. After a while, her entire fist is buried deep in the asshole.
