I felt my torso growing and growing outward. My chest was feeling very very warm. I had a horrible pain in my temple.
I noticed that my skin was growing hairier, and my fingers started to grow black. Then some thing terrifying happened. I couldn't feel my manhood! I checked my pants as I could feel nubs growing on my head, and I found only a hole, as my pectorals started inflating.
I could also feel my nose growing out and my mouth growing too. I looked back at my hand and saw only 3 fingers with large black "fingernails?" and white fur.
Then I felt a horrible pain in my tail bone, and then it became longer? I looked over my shoulder, and saw a tail with some fur growing at its tip growing from me. I was becoming a cow! My bulges on my head then erupted, becoming two long horns. My toes started melting together, forming what seemed to be hooves.
My face continued pushing outward into a snout. I was getting bigger, and getting more and more fur as my clothing started to rip. I then felt my lower chest starting to bulge. It was forming some sort of ball. It felt heavy and filled with warm fluid. I then felt four sharp pricks in that area. My ears started to flutter and flick around.
Suddenly, the pain stopped, but I still felt very heavy. I heard a the sound of splashing liquid as I stood up. I felt tipsy as I stood up. I looked at my body, and it was weird. I was some sort of humanoid cow now. My udder was humongous, spilling out of my ripped jeans still staying on. My feet had become black hooves, just managing to hold up my weight.
My skin was now covered in black and white fur, my hair now long gone. In my hair's place, two long pointed horns grew. My hand were still hands, but I only had 3 fingers on each hand, each ending in black hooves too.
My face was not that of a cow, yet retaining my eyes and ability to speak. I was about 7 feet tall now, not including my horns. My chest had inflated into a bosom, even though I had teats on my udder.
I then had an idea. I went up to my parents room, and put on new clothing, still letting my utter hang out. I sat over a bowl, just high enough for my new breast to not be in. A little anxious at first, I pulled on my udder, and milk came out.
And surprisingly, it felt amazing! It felt sexually arousing and rather fun. I continued to tug on myself as warm milk fell into the bowl. When I was done, I put some of my milk into a glass. It tasted sweet and creamy, and I loved it! As the night went on, I cannibalized some old vacuum cleaners to make a milking machine.
When I finished, I aligned my teats with the machine and activated the vacuums. It felt amazing! It honestly felt something like oral sex. I mooed in glee as my milk flowed into the tank I made.
It was going all fine and dandy, but then:
