Natural Gravity Morphs (NGMJ) for Jessi is a set of morphs that mimics the gravity force on the breasts like in the real world.
The default shape of Jessi breasts are designed to be clothed so if you want to make a nude render with her the final result is not very pleasing or natural.
Breasts are soft and with some weight due to their size tend to move down attracted by the gravity force; they move down conforming the chest as they grow in size.
