Indeed, Foxy started with smaller goals, but seems to really love her boobs getting larger and larger. With her internal bra, all that expansion is only going to make them higher and wider. I think it was reported that they are 10k expanders and I am quite certain by that time, Foxy, as her sideboob increases, will be limited to passing things from one hand to the other above her boobs and with already incredibly round boobs, she will see the crest of her boobs rising higher and higher. What a amazing sight and I imagine a wonderful feeling.
