Breast Expansion in Fairy Tail ch486

[BassGS]

On their way to take on Zeref's forces on a giant sized Happy, Lucy tries to get Brandish, a mage capable of Mass Manipulation magic to return Natsu head to normal but only to have Brandish alter her bust size making her smaller first then making her chest almost double its original size.
It happens on page 12 but there's not much in the way of process.
Poor Lucy, I can already see the LucyXBrandish doujins that are gonna come from this.
