When a woman's breasts droop to the sides as if someone is playing Tug of War with them, they are repelling each other in such a manner that they act as if they are magnetic poles that are repellent. Kind of like when one man is pulling on the right tit, and one man is pulling on the left tit.
Picture a nice, droopy, saggy pair of breasts. Now picture a thick rope in place of those breasts, now picture two men, one pulling on each of the ropes in opposite directions, make the boobs separate and go in opposite directions.
