Ken watched as the canine features gave way to a handsome muscular male form. Jeffy was still recognizable under all the new muscles. He was now 6' 4", weighed 245, and had 7% body fat. Ken hadn't changed his body hair settings, but since he was bigger, he looked almost shaven with his light 16 year old dusting of blond hair on a developed adult body. His hair was just the right length. His eyes were brown, and he blushed all over, as he realized he was naked in front of his brother.
"Ken, oh migosh, bro, I'm sorry, I'll put some clothes on. Did you need the computer? I'll carry it right over to your room or you can use it here if--" Jeff rambled.
"Shush, Jeffy." Instantly, Jeff stopped speaking and looked attentively at his brother Ken. He was awaiting instruction.
Ken put the dog whistle to his lips, and blew.
Jeff's ears perked up. Literally, they became a bit pointed, as did his teeth, and his body hair increased. A few more blasts of the whistle and Jeff was down all fours wagging his tail. At the sound of the tenth blast, Jeffy was a champion Great Dane.
"Here boy!" the dog ran over to Ken and buried its nose in his lap. Jeffy inhaled deeply memorizing his master's scent. He was a good dog.
Ken smiled, and whispered into Jeffy's ear, "Stand tall, Jeffy boy!"
Instantly the handsome dog became a handsome man. His coat of dog hair was reabsorbed into his naturally golden flesh. Jeff inhaled deeply, and opened his eyes. He blushed again and got to his feet. He licked his lips. His hands instinctively covered his naked crotch.
"Uh, um. Ah, Ken, I guess I tripped."
"That's okay, Jeffy."
Jeff sighed in relief. He could still smell his brother's crotch.
"Actually, Jeffy, that gave me an idea. Why don't you get back on your knees?"
Jeff swallowed hard and complied, what did his smart, handsome, big brother have in mind?
He licked his lips and stared at Ken's crotch.
Ken looked down at his lap, and shook his head.
"I don't think so, bro. At least not yet. I was thinking you could give me a pedicure." He tossed Jeff the nail kit that Jeff had gotten from Aunt Sophie for his birthday last week. "Get to work!"
Jeffy caught the kit, and leapt to his brother's feet. He untied his smelly sneakers and pulled his sweaty socks.
"I'll go get a bowl with some water and soa--"
"Nah, you can use your tongue, Jeffy!"
"I can!" Jeffy's face lit up like he won the lottery. His head dropped to Ken's feet and he started licking away the dirt, lint and toe jam.
Ken laughed in glee, they were both enjoying this. He couldn't wait to try out the chronivac on some other people. He smiled in wicked anticipation.
