Chad felt his paws change. He had fingers, and toes, hands and feet. He was human, but he was still tiny. He was a tiny naked version of himself, and he suddenly was super horne. He looked down at his throbbing cock and up at giant Karl.
"Wait! Wh-"
"Shut up, Chad. Anyone else who looks in the cage will only see a dog and will only hear a dog. I thought I'd give you one last night to have sex as a man. And I guess, it's Attila's first night to have sex as a man. Nighty, night."
"Don't worry, Karl, your dog will be fine."
Chad turned around to see a naked hairy muscular giant of a man sharing the cage with him.
"His, I'm Chad. You must be Attila?" Chad said nervously staring at the silent black haired giant's swelling manhood. The giant took a step toward Chad.
Karl looked down at the iPad in his lap. He was just outside the vets office. He had hacked the CCTV and zoomed in on the cage containing Chad and Attila. The Chronivac's perception filters didn't work on machines, so Karl had a good live stream of the action unfolding. He had already programmed the Chronivac to restore the two dogs to their canine status at 6 am.
