I could buy that she makes a few adjustments, but nobody is going to convince me that she isn't prodigiously stacked regardless.
I found at least 1 video and those are hard to shop. So I can tell she has very big boobs. But she also does shop them even larger. There's a ton of examples online to see this. And based on the style of all her tops it's possible she stuffs too, like Annie Keenan. Probably she grew very big boobs and wanted them even larger. Probably they are quite a bit smaller than all these pics and not crazy huge like the pics seem, but still very big. I'm guessing she's overweight and around a K cup then shops and shops some more in the chest, while taking some off the waist. Maybe she's smaller than that under the padding, but still very big.
EDIT: I did a little searching and she is frequently accused of stuffing too.
Her big boobs probably gave her popularity in school, so she stuffed them even larger, and then when she takes pics makes them a little larger than that while shrinking her waist with a poor quality phone app. She's probably a "normal" huge boobed girl and not "mega".
