Jake set the furry cap with two mounted horns looking like some spanish fighting bull might have once had. He smiled at everyone looking at him and then something snapped.
Like feeling the growing of tree's roots from the silly cap and down into his skull he felt his brain sense a burning pain. He closed his eyes and whenced from the feeling.
As he again opened his eyes the world now looked very strange. All colors were nothing more than a dull flat blend of gray and black. He shook his head feeling the obvious weight of his horns but also the sensation of his entire head being now bigger.
Hands raised up quickly to touch his face but as they came into view he saw the sprouting black hairs. A furry suit of smooth black hair was growing out his arms and the backs of each hand. He looked to others standing there and saw the expression of terror and amazement.
Looking this way and that he felt a nervous bit of personal terror building as what he placed on his head was going to make him a Bull.
One gut wrenching pain bent him over at the waist. He moaned twice but on the second groaning moan it sounded more like the pained bellow of some bull. His guts were on fire and his groin twitched and felt as if something was yanking on his penis.
Lifting one leg up from the wrenching pain it seemed to change as he would put it down and back to the floor. Then the other leg did as the first making him feel as if he must remain hunched forward.
Tearing of cloth, his shirt stretched till bursting buttons and seams tore away leaving all to see Jake's muscle building back.
Pants too tore in half and fell to the floor in a heap. Jake groaned out more bullish pained sounds as he felt what was to be the new him work away what was human.
Minutes passed like hours as Jake felt and watched in graying views his body change and mutate from human to bovine. It was as he saw fingers become as cloven hooves the real fact of how he was to walk on all fours suggested he fall down and take the position of a bull.
Shaking his growing head Jake could do nothing but eye his bullish self and long for never having come to this place.
"Here we have the finishing touch to your own personal costume!" said the shop's propreitor.
Reaching his hands before Jake's broad black nostrils he jabbed into the bridge of a bull's nose one brass nose ring.
Jessica the pervert mind of one female and blonde nitwit saw Jake standing there as a bull. She walked right up to his black muzzle and wrenched down her hot pants to grant the bull a sniff.
Jake being now more a bull in sexual preference, took a deep drag breath of Jessica's ripe scent. He mooed his delight as he began to become erect.
"You like me now, don't you Jake!" chidded Jessica to the bull.
"You want to join him, he'd appreciate you well if one wants to become a cow?" asked the proprietor.
