Nate pressed the inanimate button, and shortly after his mother's dress started tenting a bit around her abdomen. Four bulges started forming in her shirt as four tubes came out of where her belly button was. That was all that was visible though as Nate's mom's internal workings were shifting, especially in her breasts which were turning into boob shaped milk tanks.
Nate's Dad asked "Come on honey, can't we just milk these now?"
"It's too much hassle. We'll just wait till they get more full." Nate's Mom said and then Nate wanting to see what it would look like pressed a button on the remote for body modification and suddenly his dad's udders started engorging and enlarging as they became full of milk and were starting to overflow. "Or now..." Nate's mom lifting up her shirt showed her suction cups and after she placed them on her husband's teats she seemed to concentrate and then the sound of a vacuum cleaner or something like it occurred as her internal milk machine started sucking her huband's teats. The pressure in the udder was being releaved, and the Nate having imagined how his mom's internal workings worked started at her chest and her boobs were starting to expand. There was a lot of milk in those udders and they were going straight to her breasts. Infinitely expandable, and detachable in order to drain. However till she had the time to drain those boobs they would stay big.
Nate's mom sighed as she poked her enlarged breasts and sighed "I think you're making more and more milk. One'd think you'd make less with age."
His father chuckled and said "Hey what can I say? I'm healthy as ever, and it's not like we needed to take you for a tune up."
