Quick Poll~ How should Shenhe's breast expand~? (Patreon)

How should Shenhe have her breasts expand during part 2 of the render I wonder~?
Part 1

Part 3

Shenhe will be growing to that size~

It will be a quick simpler animation or at the very least an image sequence, since I most want to focus all my attention on the 3rd part which is Shenhe erm ... using her new assets hehe~

As usual Tier 3 members get x5 votes~
