Kathrine smiled softly and leaned in, her three fingers quickly found her mother's wet soft pussy, "I will mom.. I'll make you cum..", she whispered before taking in that nipple, sucking hard on the hard nubbin of pleasure, the same second three of her long smooth fingers drove into her mother's squishy pussy before she raised her fingers, curling them back and quickly starting to ride them across her g-spot. "That feel good?", Kathrine asked as she went for the other nipple, giving this one a rougher treatment, lightly grinding her teeth on it.
