I agree. They will always find a way to make money. Around here there are slot machines even though it is illegal. They just take prepaid calling cards instead of currency. Right next to the slots is a machine that take money to give you prepaid calling cards! Bingo...all nice an legal!
I would never use a credit card on a pay site anyhow. It leaves a finger pointing right at you!
I will say that a few of the man mare commercial videos were better than the fem horse ones. But they often ruined it for me by doing money shots. One of the great beauties of zoo sex is no worries about pregnancy, so there is no reason a real zoo would pull out except to play for the audience.
