For how long she's been at the facility, you're surprised she doesn't have a nickname yet; at least not a /real/ nickname. As far as you've heard, she's been called pretty much every "milk" related nickname you can think of. Some of the names sound pretty rude, likely picked by someone mad about cleaning up gallons of milk.

Anyway, /the Miltank hybrid/ has a bit of a genetic flaw, she can't stop producing milk in her vastly oversized udder-belly, causing constant waterfalls, oceans and other big messes you're glad you didn't have to clean up.
At some point before she was assigned to your team, some tech got real grumpy with her and decided to tie off her teats and pass her off to someone else: you.
Luckily for you, the buildup only got so far before she hit some kind of equilibrium, settling on her current size.

You check her data. During a week she had her production completely shut off, she had roughly the same build as Payya; her head's a little too big for her skinny body in the attached picture, but otherwise she seems to have a pretty nice build under all that belly.

(Huh, I hope those teats don't count for "nudity", I highly doubt I'm going to cover them up too often and I like to post things under the general tag every now and then.)
(Mainly all I still need to tweak are some mouth shapes, tweaking her teats a little, doodling a bunch of eyes, and maybe fiddling with her hands and feet a little more.)
