Rob suddenly groaned as something changed inside him. He saw four pink nubs forming below his stomach. The skin underneath the nubs was pink and raised a bit. The space ballooned out, making Rob gasp. The pink skin grew out until it was at least two feet long. Rob knew he had an udder too. His udder moved down, settling between his legs. Rob couldn't feel anything between his legs except for his udder, meaning Rob was now technically no longer male. He rubbed his new udder, and could feel the milk sloshing in it. He couldn't believe it!
