Your a researcher at a station in space. You had a food problem and found out some of the colored rocks on this moon had special properties that increased milk production, and also made them cows... though avery, the nutrion officer, has got the better (or worse) end of the stick! her thighs and butt grew to a really big size other than her chest though she still produces milk like the others! The seamstres of the ship had made her yoga pants to actually fit her ass, she did a good job! you go to check in on her

Oh, Hi lead researcher! I was just studying how the milk works some more is all, did you need something?
