Naughty lil sis is so enthralled by her Big bros cock that she can't help but suck and drool all over it while she talks about how big it is and how much she loves getting to suck on it for him!! She begs him to cum in her mouth, talking about how much she loves his cum while she keeps deepthroating, gagging and drooling all over his huge cock until he eventually blows a huge load right in her mouth!!! She swallows as much as she can, but it's such a huge load some drips out!! So she licks his cock enjoying every drop and she sucks on her fingers and rubs his cum all over herself!!!!
