I tried to say something, but instead vomited. All the fluids were being pushed out of me as my body trembled and ached. But what I felt most out of all that I wasthis weird pressure in my balls. I looked down to see them swelling rapidly, the skin of my scrotum stretching taunt as they ballooned between my thighs. Which also seemed to be swelling. Four angry red growths began to appear and grow along with them as my manhood shifted and puffed up into one big, heavy orb with four fleshy growths, almost like...
An udder! I realized with a cry of fright. A big cows udder, hanging heavy below my cock, which looked small and sad resting about my new organs. It grew fuller till the skin was tight and you could see the veins beneath the skin. I almost cried out in pain before a sudden stream of milk shot out from my teats. Relief flooded over me as the pressure releived itself. And my cock started to twitch and harden as the relief was tinged with a bit of pleasure.
And then fear as I saw what was happening to my manhood.
"No No no..." I moaned as I watched it shrink down to a little nub, before disappearing with a big squirt of what looked less like cum and more like a stream of milk to match that from my new dairy bag.
I saw my thighs were growing as well, swelling with fat as the milk drained itself from me. Below my knees my bones cracked and reshaped themselves, turning into digigrade legs as my feel shrunk up on themselves, leaving me with the legs and cloven hooves of a cow. Compared to my human torso, my hips and ass were outrageously huge. I felt something grow from the base of my spine as the skin below my waist itched. I grew a tail as brown and white splotches fur sprouted. I felt a weird wetness between my broodmother thighs as I realized my lower body was that of a very milky hucow.
