The spherical, bouncy objects on the front of a womans chest. It carries milk, fat and veins in a way a bag might. At the front of this bag, is the entrance to these magical objects. This entrance, is a round pink circle on the centre of the bouncy bag. Some have named these pink circles 'nipples' a nickname coined in the iron ages. Therefore, this magical object has adopted the name 'nipple bags'.
My girlfriend has perky, bouncy, succulent, nipple bags. I love to motor boat them.
