love the story so far, chapter six got me thinking with the milk machine sequence though, any way we could see some permanent nipple growth from using the machine? id love if mirai got hooked on it and she got some real teets more in line with actual dairy animals. i love the expansion theme so my mind runs wild at the possibilites. ill keep my fingers crossed for some more different types of growth but you do you! keep up the good work. ;3
