Carmen Rivera, the ultimate femdom queen, indulges in her favorite pastime - fisting. She straps her submissive to a device, ensuring he can only watch as she pleasures herself. Carmen's juices flow as she inserts one, two, three fingers, stretching her cunt wide. She adds more lube, pushes harder, and finally, her entire fist disappears inside. Carmen's moans fill the room as she pounds her pussy with her hand, her submissive's cock aching with envy.
