^I think the allure, the feelings that huge boobs give her, may just outweigh all the ways they make life more difficult. It isn't just walking around and showing off how huge your boobs are, it is about how happy you are with their size all the time, even when trying to reach something in the back of the fridge as your boobs are pressed against a lower shelf, limiting your reach. You learn your limitations and are happy to live with them.
