Samantha looked at her children and could see the hesitation on their faces.
"Sweeties it'll be okay. I promise. Your father is a full dairy cow now and it's perfectly natural for him to be milked." She ran her ebony hand over the light pink veiny flesh of her husband's four teat udder as she spoke. "Besides. Your father here is very full, he's probably uncomfortable. If we nurse off him, it'll make him feel better. Won't it honey?"
Tom let out a low moo and shook his new massive head in agreement. The weight of his newly developed udder was making him wish they'd just milk him already.
"Here, I'll go first." Samantha stated as she slowly knelt down on her knees, next to her husband's hind legs, his massive udder directly in front of her. Tom lowered his head and looked back at his black wife kneeling next to his rear end. Samantha looked into her husband's dull cow eyes. Samantha could still see her husband of many years in the cow's eyes.
"Please...." Samantha started ".. be a good mother to me...." And then she leaned over, opened her mouth and placed one of Tom's swollen pink teat in her mouth and started sucking.
Tom moo'ed in relief as he felt milk from his udder being sucked from his body and into his wife's mouth.
"Mmm ....MMMM!" Samantha moaned in enjoyment as she started sucking harder. The warm milk tasted a little off to her at first, but the more she sucked, the more she was loving it!
Tom and his children watched as Samantha's body started to crack and expand, slightly. He body did not grow much larger like Tom's had, seeing as she was turning into a calf and now a fully grown cow. Black and white short fur started to cover her dark ebony skin. A small tail started to press out above her nice black ass.
Her legs and arms started to snap and crack as the bones beneath her skin started to reshape. Soon she was standing on four calf shaped legs, which looked odd with her hands and feet still very human. Her back snapped and arched as her ribcage expanded out. Her internal organs growing and changing to fit her new form. Her stomach started to break into four pieces as she her belly, once fit and tight, expanded and ballooned out to accommodate her new stomachs.
Her fingers and toes started to harder and turn black, as they curled inwards to form four calf hooves. By now, Samantha had the body of a nursing calf, all except for her head. This soon changed as her ears started to grow larger and expanded outwards. Her mouth and face started to push outward as well as he took the shape of a calf. Tom could feel the force of Samantha's sucking started to increase as her head transformed into a shape more suited for nursing off his udder.
Finally, after only about 3 minutes, Samantha stood in their dining room in the body of a cow calf, happily sucking milk from the teat on her husband.
Tom continued to watch his wife feed. He felt an odd sense of pride knowing that it was the milk he himself had created that had caused his wife to transform into this beautiful calf nursing on him.
Tom finally took his gaze off his nursing wife and looked over at his other children. Both of Tom's human children had a took of shock on their faces. They couldn't believe they had just watched their dear mother submit her own body to be twisted and transformed into the body of a baby cow, while sucking at the udder of their own father!
Tom could see the hesitation in their expressions. Tom loved his children and didn't want them to do anything against their will, not again. But at the same time, Tom had a desire to feed them his milk. To watch their bodies transform and be reduced to calf's and feed off his milk. He wanted to take care of his family.
Tom moo'd pathetically at his human offspring and motioned with his larger head towards his rear, where their mother remained, still sucking away at Tom's swollen teat.
