Jack decided to go home to test out the ring, because of his massive boner he had received seeing the beautiful lady with her dog's tail on her big rump. He quickly wished that she would think having a dog's tail was normal.
He arrived to his house, thinking of all the amazing things he could do. One of his fetishes was human evolution. What is humans had evolved from something other than primates? What if humans had four legs? Things like this made him horny.
He pulled up a website that showed nude ladies and seeing this one woman with massive hooters gave him an idea.
"Until I say otherwise, I wish women had udders rather than breasts."
He felt the ring warm up and he had to blink for a few seconds. When it was over he looked up at the screen. The picture of the woman had changed. First, her breasts were now gone. Her chest was completely flat with no nipples. As looked lower, he saw she now supported an udder under her belly button. She had four nipples, more like teats on a cow, on what looked like a giant boob. 'Wow' he thought as he came all over the screen. He cleaned it up and then went to the window. Looking out he noticed some women walking. It was obvious they now supported human udders. But like breasts, they had them covered up. From what Jack could see, women now had bra like belts to support their udders. He noticed another woman whose shirt was open enough to show off the top of her udder like cleavage use to be.
"This is awesome. I wonder what else I can change."
