It's the summertime, and I'm vacationing at a farm, shoveling cow pies. At first, I don't notice the subtle changes to my body: my face slowly changing, my gloves tearing, and four strange bulges appearing on my lower stomach!
I quickly drop the shovel as I notice my hands tear free of my gloves, while my face continues to change, the bulges on my stomach get larger, the buttons on my shirt start straining, and my pants tear as well!
I moo in euphoria with my changing face, as my body tears free of my shirt and overalls and buttons go flying. A tail snakes out of the back of my pants and my boots start straining, as the mysterious bulge on my stomach continues to push at my overalls.
I look back at my changing body, as an udder finally breaks free of my pants, causing the other strap of my overalls to brek free, and hooves tear free of my boots. I am unable to continue standing on two legs at this point and start to lean forward.
The transformation complete, I simply stand there and take a look at my new body, while scraps of my former clothing laying on my back and the ground. Hopefully the farmer takes the hint and finds a way to changes me back!
