You find the day's events a bit tiring, let along the walk home. It should be that far, but it feels harder and harder to move your feet after a while. It's a swelling and slickness that's from the soaked feet that you look down, finding things tapping at the sidewalk. Your feet are starting to darken and stiffen. Crunching and slick noises as you fall to your face. Your thighs are rubbing together as you press along the ground.
There's a wet rush of fluids as your skin starts to change on your legs, growing in a pure white and black hodge of bovine nature. Your legs changing into that of a rubbery cow of sorts. You struggle to stand up, but your feet aren't done yet. The sensation of your ankle and toes cramping together is making you wince and wanting it to be offer soon produces a sense of relief as you find a pair of smooth black solid rubber hooves where your feet used to be. You gaze down now, wanting it to be a dream, but there's a much better indication that this is far too real as your slick front begins to feel tender, an udder growing slowly, the nubs of teats filling out as you start to stand and rush quickly to your house... or your shop... or .... anywhere but standing still... as you realize the nature of the transformation and your new udder, already, you're leaking milky latex in a puddle and your bottom has started to shift into a bovine's slowly now, your lower half almost fully changed, save for your spine thankfully, allowing you to awkwardly walk on two .... hooves.
It's only as you make a path foward to the next place of safety that you let out a low moo, a lengthy latex tail swatting behind you as milk runs down your thighs, leaving a shimmering latex dripping puddle of shame to go with you as you will yourself forward.... where shall you go to resolve this rubbery mess?
