Sam was excited when he picked up his new dog Max at the veterinarian's. He hadn't told Jeff about his new pet. But he and Jeff had been friends for years, and he had been envious of Jeff's relationship with his dog Sally. Now he'd have the chance to have the same type of relationship with Max, and he and Jeff could hang out, while their dogs played together. He had just paid the vet's bill, when the Chronivac wave swept over him rewriting Sally as a human being. For a moment Sam zoned out. Sally wasn't a dog, what was he thinking? He blinked, and his memories rewrote themselves. He wondered for a moment, if he only hung out with Jeff because Sally was always there, and she was so hot. Nah, he and Jeff were best friends. He knew Sally and Jeff would be pleased to meet his new dog Max. Sam led Max by his leash to his van, and secured him inside. The veterinarian was on the other side of town from Jeff's house, and there was a lot of construction work, so it would be a long drive. Max whined. Sam decided to stop at a park to walk him.
He really got into playing with him, after he cleaned up his business. Max was a rescue - like Little Max, and he loved running free at the dog park. He was a bit uncertain about his new master, but he was grateful to him, and he really did seem to care about him.
They were just finishing up, when the next Chronivac Wave hit. Jeff- best friend? Man's best friend - Jeff was man's best friend, he was Sally's dog. Damn, Sally was hot. He grinned looking at Max. This was perfect, he had a dog, and Sally had a dog, and if they maybe he could get Sally to see him as more than a friend.
"Hey, Max, you wanna go meet a dog? Good thing I didn't have you fixed, I think Sally and I will be closer than ever, if you have puppies," he said as he loaded Max back in his van.
A half hour later, Jeff was totally canine, and Sally was answering the door to Sam and his new dog Max.
"It's a beaut, Sam. Is it yours? Or are you dog sitting?" Sally said squatting to pet Max.
"All mine. I figured they could play, when we go to the beach or park," he said with a mischievous grin.
Sally looked up passed Sam's bulging crotch. His musky odor was turning her on. She was a bit confused, how did he know Jeff was a dog? Then it hit her. She and Jeff were aware of their changes, but the Chronivac indicated that the device would adjust other perceptions to meet the new reality and minimize mental trauma. That meant as far as Sam was concerned, Jeff had probably always been a dog, or perhaps he thought Jeff was a weredog? Good grief, what would Jeff's parents think when they got home? Would they be dogs now too? Sally hadn't considered those implications. She stood and turned hastily to conceal the consternation on her face.
"Or perhaps they could get to know each other in your room?" Sam suggested.
"Mm?" Sally said. Maybe Jeff wouldn't be the first human to have sex with her. She then decided to change Jeff into a female and have her going into heat. She glanced at Max. She then told Sam she needed to use the bathroom and went into where the computer was and changed Jeff into Jennifer, Sally grinned, Max' canine senses would take care of the rest, so she said, "So you wanna come up to my room, big boy?"
Sam nearly jumped out of his skin, "Yes, Sally."
Jeff was licking himself but it to licking his new cunt. Damn, he wished he could do this while he was human. He was oblivious to Sally coming in with Sam, until the waft of pheromones emanating from Max hit him. He stopped licking, and became attentive.
Jeff then noticed that the other dog was male and that for some reason could only stand still while the other dog came up to him and then before he could Max had mounted Jeff. Sam and Sally had then also started having sex but had forgot to use a condom.
