You are an ordinary white skinned boy, there is nothing special about you right now, but something amazing is about to happen to you. You suddenly get the urge to pee, you try to hold it in until you find a stall and a toilet. You manage to find one and get to it on time. As you sit on it to relieve yourself, your clothes dissolve and vanish into thin air leaving you completely naked. When you pee however the liquid coming out of you is not clear or yelllow but instead it is white. Your scrotum bulges out and it turns pink and baggy, then your penis multipies and splits into four and they settle in the corners of your pink baggy scrotum, they are pink And 6.6 centimeters long and 2.9 centimeters wide. You see that the toilet that you are Ejaculating into disappears and it is replaced with a bucket, you also learn later that you are not urinating pee or urine and you are not ejaculating sperm or semen or cum but that you are lactating delicious creamy dairy milk. It is official now, you are a cow. As soon as the realization hits you more changes happen, your breasts and nipples disappear into your chest, making it Barren and Featureless. Your navel or bellybutton or belly button becomes that of a cow's. Your face becomes a muzzle of a cow's. You sprout white fur on your body with the occasional black spots on parts of it. You grow horns on your head. Your hands and feet turn into hooves. A long ropey whiplike fleshy later furry tail with a tuft of fur at the end of it sprouts from your tailbone just above your anus, and you can't talk human language anymore. You also grow another hole below your tailhole, it is your vagina. You pee milk from your udder for all of eternity and even beyond that. Your Milk is collected by a Bucket in front of your rear legs.
