Luke stood smiling as he held up the cow suit he had made for his girlfriend. His girlfriend had begged and pleaded him to make her an animal costume, so he had done it. However, being the great guy he was, he decided he would add a special surprise so she would stop being a bitch.

Luke had met his girlfriend, her name was Amy, a year ago at a party his best friend had thrown. They had hit it off immediately and had begun dating the next day. The relationship went great for the first two weeks, but then Luke’s life had become a living hell. Amy would spend all his money on stupid clothes and other girly shit. Luke only brought home so much money a week, and she wasted at least three-fourths of his cash in a single day.

Now, Luke had devised a way of getting even with Amy. Amy had found a flyer for a costume party where everyone had to wear animal-themed costumes. Being the bitch she was, Amy had already spent all of Luke’s money so she couldn’t buy a costume. Luke had always been good at making costumes and things like that. She had told him to make a cat costume, but he, having connections, had a friend enchant the materials he was using so that whoever put the costume on would become an anthro version of the animal the costume was made to look like. Since she had pissed him off, Luke had decided to make a cow costume.

Luke hung up the costume and smiled at his handiwork. He had made it the perfect size for Amy. He had also included a few special features. The costume had large breasts on it, larger than Amy had ever had. They were technically mini-udders since he had put four long teats on each one. A huge udder that would make it hard for her to walk hung between the suit's legs. He had made a vagina in the position where a real cow would have one, so that when he wanted to bang her, he wouldn’t have to move her udder out of the way. The head was a cap that had long cow ears and horns on it. It would make the wearer appear completely bald and, once the magic took its course, they wouldn’t have any human hair. It truly was a work of art, from the three fingered hands to the two black rear hooves.

Luke turned around to walk into the living room and wait for Amy when he was struck in the face with a large metal object. He went down faster than a ton of lead. Over him stood Amy frying pan in hand. Luke’s friend had told her about Luke’s plan. So now she was going to turn the tables on him.

He always yelled at her for spending too much money on clothes and things when they were mostly for him or the house. She would make it so that he wouldn’t ever have a chance to yell at her again. She took the suit down from where Luke had hung it and turned around smiling.

Luke awoke feeling odd. He stood up realizing he had been on the floor. As he pushed himself up, he realized something else, he was wearing the suit. He tore at the suit trying to get it off before the spell took effect, but it was too late. The first part of the spell made the wearer of the suit passive so they would obey the person who put the suit on them at anytime. He just stood there as the magic flowed through his body. His body was passive, but his mind had not totally been taken over by the spell. He screamed inside as he felt the changes begin. He screamed again as he saw Amy walk around the corner.

“So, Luke, it looks like you’re enjoying the suit you made for me. You know you really need more reliable friends. Flash a little cleavage and they’ll tell you anything.” She walked up to him and touched one of the breasts on the suit, one of the breasts that would soon belong to Luke, or maybe Bessie, since he was soon going to be a female and a cow soon. “You’ll know that soon enough though, with how big of breasts you put on the suit, and how did you expect anyone to walk with that big of an udder. Tisk, tisk, tisk, Luke, how foolish are you?”

Luke wanted to call Amy every name in the book, but the spell was too strong. The rest of the spell soon took effect though. He could feel the suit becoming his skin. He could feel all the fur become one with his body. The pain was excruciating as the fur rooted itself in every pore on Luke’s body.

Next, he felt the horns root themselves into his skull. He would have been screaming if he could, but the spell held. Suddenly, he couldn’t hear anything. Luke wondered what the hell was going on, until he realized that his old ears would have to disappear if the new ones on the suit were to become real. Suddenly, with a loud pop the suit’s ears became his. They began to flail wildly as they connected to the nerves, veins, and ligaments that would truly make them a part of Luke.

Amy just watched, smiling. She had wanted revenge on Luke for so long. She rolled up her sleeves to look at the bruises Luke had inflicted upon her last week. He had always been so violent. Maybe being a girl would make him mellow out.

As Amy continued to go over all of that, the changes continued to sculpt and change Luke’s body. Luke felt the world’s oddest sensation as the suit's mammaries fused into his body, becoming his own. Almost as soon as the fusing process was done, the three large glands began to fill with milk, causing Luke a severe amount of pain.

The changes were just about finished as the magic settled in Luke’s hands and feet. The toes and finger fused together so they resembled the outline the suit had made for them. The magic ebbed and flowed through his whole body once the changes to his extremities were finished. Small amounts of fat showed up underneath the skin, destroying any of the muscles Luke once had. He also shrank down to a more feminine figure. After all was said and done, he was a cow-woman, nothing more, nothing less.

Amy smiled as she grabbed the cowbell down from where it hung. The name Bessie was carved in it. She snickered as she thought about how Luke had been going to rename her once she had put on the suit. Too bad his plan had backfired. She put the bell around his neck, and any thoughts of resistance disappeared. Luke, now Bessie, was completely under Amy’s command.

“Well, Bessie, looks like I win. I hope you enjoy your new form. I mean, I know all the men I’m going to sell your services to will enjoy it. Now, before I find our first customer, let’s make sure that everything was made right.”

Amy went over to Bessie and fliped her over with one arm. Bessie landed on her breasts and udder, causing some of her milk to be forced out. Amy smiled as she saw the perfect vagina Bessie now sported. She put a hand in it to make sure everything worked and Bessie began to moan in pleasure. Amy’s smile widened as she now knew that she had all the power in this relationship.

Epilogue: Amy indeed kept her word about selling Bessie’s services. Amy was a very sadistic master though, as every time she would find a customer, she would remove the bell from around Bessie’s neck, causing all of Luke’s old memories to surge back, striking him with the horror that he had gone from being a successful human male to an even more successful cow woman prostitute. Of course, he would be forced to acknowledge he was being raped by a man and his mind would try and close itself off trying to block out the horror, but he would always lose and be forced to feel every disgusting pleasure as he was raped.
