(WIP) the Pink Vial: Breast expansion (Patreon)

Here is the breast expansion that happens to thing lucky victim in my upcomming animation video: the Pink Vial.

The commissioner of this piece wanted the breasts to pulse little by little. Whuch has something cute in it. 

I like that I for once do a science-themed animation. I don't think I have ever made an naimation with that theme.
