Fat experiences

I was wondering how big would moobs need to be for jiggling or even bouncing while walking?

Never had that because of small moobs but it would be so hot to have so big moobs that they would bounce during walking.

Size is not the only aspect of jiggling. This includes women. Some are perky and large and don't jiggle much. Some are small and saggy and jiggle even at an A cup.
