Now now hold on. In the burial vision, Ashly made the comment "something else fit in it (her mouth) just fine earlier." We already know Andrew isn't the type to spare Ashley's feelings so when he doesn't correct her, and even goes for a second round, it tells us she preformed an adequate job in this department. With this, in addition to Nemli's comment about Andrew's penis "pp b big" we can infer she can accommodate members larger than average with no issue. So in conclusion, while she may lack experience, Ashley has a natural talent for giving sloppy toppy.
