mOnthly grOw Illustration (Dec 2019): (WIPs 1-7) (Patreon)

This month's grOw illustration comes from Oldkid, who submitted this idea as a Black-and-White Commission entry for November:

A dark-haired woman with a loose ponytail sits in the back of a pickup facing backwards. The truck is speeding along a rural highway. She's shirtless as her breasts have grown so much that they fill the bed of the pickup up to her chin. They're beginning to outgrow the capacity of the truck and bulge up over the sides like muffins. Her arms lie atop her massive breasts. She appears anxious and aroused about her condition. 

( I added the milk theme to the image, including the idea of the truck racing to the dairy barn to milk the woman in time. )

This idea did not win the November poll, but I liked the idea, so I used it as the mOnthly grOw illustration for December.
