This is really funny

Thank goodness she didn't stuff her bra, that would've been cringe worthy. You certainly have an aptitude for storytelling/animation, I hope you're continuing to be creative, maybe even come back to NG and have some fun here!

well i only user the vocal rinser and ready to go

Let's just say Im glad I'm a dude.

haha, nice, cute little animation!

Great start for, what I assume is, your first animation?

I would only suggest that a simple rearranging of shots could make it a bit funnier.
For example, when she draws attention to her breasts and it cuts to "...". If the next shot was of her bouncin dem boobs and THEN revealed that she used a push up bra, rather than revealing it before hand, you would have created a stronger comedic effect.
This is because it helps build tension by making the audience question or wonder for a moment how the transformation happened and then relieving that tension by explaining the sudden increase of boobage with the bra reveal.

Other than that, keep it up!
