"Well look ov'er boys!" shouted one hayseed looking teenager to a group behind him.
You raise your head and suddenly at the fence there is a mob of 5 teenage boys all staring you down, pointing and starting to laugh.
"Looks like the magic shop got us another free breeder," croaked the one as you feel yourself swell up with every breath, your torso expanding.
"H-help me!" you beg as best you can. You winge as you feel your tufted tail brush against your swollen fat cow ass.
"Help?" one laughed.
"You?" finished another with a louder laugh.
"Whoever puts those rings on becomes a big breeder cow every-single-time. You're one of the few to walk here though so you saved us the trouble of hauling you off!" chuckled one in a cowboy hat. "I've been waiting to see the look on one of your eyes when it hits you you're a real animal," he added cruelly, spitting.
Your fingers began to harden and cramp into new hooves and hands were now part of forelegs. What WERE you becoming? What else but a big, fat...
"No... no! I have a wife I.... I..." you beg as if your shoulders weren't popping into new positions in your ears. "I can't be a cow!"
"HAD a wife!" one teased. They all laughed.
You shivered as a cool breeze brushed across your swollen bovine sex. "You'll be the mommy from here on out. Ring makes you extremely fertile and you come to term much sooner. Very good for farmers as you produce four times the milk!" the one had to add with pride.
You tried to back away but your growing arms were clumsy. You hobbled back, your udder wobbling under you. You see one of the boys running across the top of the fence towards the bull pen and the latch.
"Let's watch the bull fuck the human out of him!" the boy cheered, undoing the latch. They all cheered while you trembled at your looming fate.
