He makes her into an anthro skunk.

Even among furries, Tom had a pretty unconventional favorite when it came to anthro animals. It was impossible for him to place exactly what it was about skunks that he liked so much. Was it the fur pattern? The tail? The smell? He had no clue. Still, he rubbed the coin and made his wish. “I wish that, sometime between now and when she gets home, Sarah will do something or have something happen to her that will turn her into an anthropomorphic skunk, exactly how I’m picturing her. She’ll be scared, be easily comforted and seduced. After that, she’ll be comfortable with her new body.”

That done, Tom went about his day, until in the late afternoon when he heard Sarah’s car pull up. Eager to see the changes, he entered the living room just as she came through the front door. She was everything he’d wanted. Her entire body was now covered in black fur, with a white streak down the back that flowed perfectly into her new tail, which was so large and fluffy it was impossible not to look at it. Even Sarah’s hair had changed color, becoming a pure midnight black with a stripe of white on one side. Her face had become a muzzle, with a bright pink nose on the end and a mouth full of much sharper teeth. She looked at Tom with fear and confusion evident, even on her changed features. “What happened, honey?” he asked her, as though he wasn’t responsible for it.

Putting her changed head in her hands, which he only now noticed hard longer nails than before, she started to explain. “I was going to my car from work and there was this big car accident. Some truck, which had been carrying some kind of gas, hit a pole and whatever that stuff was got in the air. I tried not to breathe it in, it smelled so bad, but I started changing anyway. I wasn’t the only one, I saw a few other people turn into skunk people too, and for others it looked like different animals.” That was all it seemed she could tell him, because then she closed the distance and he hugged her and she cried into his shoulder.

Rubbing her back seemed to help calm her, and Tom soothingly said, “It’s going to be okay, I know it will.” That stopped her crying but she didn’t move away. Still petting her, he added, “You know, you still look pretty sexy. I bet you’re a real animal in the bed now.” That made her laugh, and soon they were kissing. It took some time to get used to it, what with her mouth being pretty differently shaped now, but they got the hang of it. The making out got heavier, and soon he was fucking her doggy style on their bed. He didn’t know if he’d ever been harder, and unable to help himself, he’d occasionally play with her tail while they fucked. At one point, he even lifted it up enough that he saw what looked like her scent spray gland, just above the asshole. It gave him...new ideas.
