What the Madame held out for Monica was a large bell dangling from a long, thick collar, much too big for any dog.
"But, but how could you know?" she asked the Madame. "I only reluctantly admitted it even to Damon. Did he tell you before the show?"
"Magic, my dear, it is magic. You witnessed your boyfriend turn into a dog before your eyes. I know you have your own impossible wish. Impossible for most, that is."
Monica touched the cowbell reverently and felt a tingle pass through her. Madame Illusia raised it up to fasten it upon her neck, but Monica gently raised a hand to stop her.
"But if I turn into an animal, too, then who will take care of Damon--I mean, who will take care of Max?" she asked in a concerned tone. Max barked and wagged his tail at the mentioned of his name.
"There are farms that have both dogs and cows," answered the enchantress. "We can even arrange to send you both to the same one. You could still spend time together. Although you may find yourselves enjoying drastically different sex partners from now on." The audience chuckled.
Monica realized the Madame was saying this was forever. If she took the bell, she was taking on a whole new life. She could never be with Damon or any of her other human companions the same way, although Damon had already accepted that cost to turn into Max the dog. Could she take the same risk? Leave her old self behind on this stage, to live the life of the animals she secretly envied, grazing peacefully in the field between milkings?
She could and she did. She presented her neck to the Madame, but the accessory was not at all comfortable around her neck at first, much too large to fit conveniently against her present form. But something about it was just right. Monica felt warmth and strangeness flowing through her body. Somehow the feelings from the cowbell started settling in her chest, so she looked down to find out what was happening there. Her midsection was growing, but her breasts were shrinking! She held her womanly assets one last time on their way out of this world, watching them shrink back into her as her swelling torso seemed to foreclose on their real estate. At last, even her nipples were gone. She wouldn't have to do without them for long, though, because two red bumps rose up on her lower belly, and then two more emerged beneath them. Instead of growing human-like breasts, though, a single wide section of skin piled up into a mound beneath her four nipples. And then the nipples lengthened into teats. The mound swelled out into a massive sack. And Monica reached down to feel the udder she had exchanged her breasts for.
A feeling like someone touching her boobs was coming from between her legs, leaving her stunned and disoriented as she prodded her arrangement. The shook her head to clear her mind, and then she felt a flapping in her ears. Their length and curvature amazed her, but it was the growth of fur upon them that really blew her mind! She mooed loudly while Madame Illusia petted her lengthening back.
A numbness in her hands caught her attention, so she looked down and marveled at the changes taking place there. She watched them fuse and lengthen and stretch. She watched her nails grow long and wide. Before she knew it, she was staring at a pair of large split hoofs with smaller dewclaws underneath.
'I've given up my hands,' she thought, 'I've really given them up to have what a cow has. I really hope it's a fair trade.'
The fur growth wasn't stopping. A short-haired coat was sprouting all around her, encouraging her that she would never have to worry about clothes again. Damon said she was sexy whatever she was wearing, but the world at large was not so kind. Women always have to walk a tightrope picking out the perfect outfit, or they'll always be considered too homely or too fat or too slutty. How much bare skin is enough? How much cleavage is too much? Cows don't have that problem.
An itching tightness past her tailbone made her flinch and look behind her. Something thin and fuzzy was slithering behind her, growing longer and slightly thicker as she watched. It grew a hairy tassel and flopped beneath to dangle in between her legs. She soon found this was optional, as she could lift and flex it as she pleased.
'Well, at least I'll have something to swat the flies with even though I won't have hands,' she thought. It already felt surprisingly good to make it lurch and slap against her sides.
She found the muzzle she was growing when she absent-mindedly licked her own nostrils for the first time. It was weird watching a giant tongue come up from below like a whale jumping from the ocean, just to give her a taste of her own snot. But the weirdness didn't stop her from doing this again. The snout grew longer and wider, while her feet grew hooves like the ones on her hands. Her size grew ever larger, until it was impossible to keep her weight upright anymore. She was down on four hooves in no time, swishing her tail and mooing from her snout like the bovine she was.
