How do you prefer Pinky: flat, curvy, or somewhere in between?
Advantages of being flat: greater elasticity, more enjoyment watching her expand, becoming a beautiful sphere.
Advantages of being curvy: greater sensuality, huge butt, and more focus on her breasts and butt when inflating.
Somewhere in between: a bit of everything, but fewer curves.
Disadvantages: none, it's Pinky, she's perfect.
