To Be A Cow - Part 5 (Patreon)

She tries to stand on her hooves, but she finds it difficult. Her ankles wobble, and the hooves don't seem very balanced. It doesn't help that she has that huge, swinging weight between her legs either. And to make matters worse, something in her back keeps her from standing all the way up straight. It's like it isn't supposed to go that way, even though she distinctly knows otherwise. Soon, though, she's distracted from that thought as something starts pushing out of her back. It feels like its stretching her spine out and she almost immediately recognizes it as a tail. She can't just watch it grow, however, as the further changes to her body flares up her sensitivity again, and she's reduced to fondling and tugging on her udder again. This time, however, she goes at it with much greater enthusiasm, and just when she's about to reach her limit, a burning, but pleasurable, feeling shoots down the two teats she's pulling on and a small squirt of white fluid shoots out of each of them.
