You have time to be suspected by your parents one day, and you will be able to face a D cup sex doll when you see a showroom in the center. Its size, weight, texture.

Depending on how it is distributed, the volume of the TPE can exert pressure on the frame at some (extreme) locations, thus increasing the risk of cracking. It will be more precise, because it depends on the distribution, the structure of the skeleton… I am talking about a normally constructed doll, not the horror of what a huge breast looks like.
