Your breastes math and the corresponding volume equivalents you use are way, way off Shirley. A US GALLON of water is approx 8.3 lbs. The exterior portion of DD cup breast is a ratio. Unless you are a 7 foot tall woman a DD cup breast is a relative fraction of a US gallon. Even on a 6 foot tall woman a DD breast would be around 2 lbs each at best.
So no, it's not 16 lbs.
