She hauled his cock up higher and tilted her face down. Another drop of quicksilvery cum was squeezing out of his piss hole. Marylou flicked the tip o... her tongue over his hot prick meat, gathering that succulent nugget of dog-jism onto her taste buds. She let the cum slide around in her mouth, savoring the flavor, then swallowed.
