"Yo, Chad, I got a surprise for you. I lied about Mom and Dad fixing me breakfast. See when I arranged for you to be alone up at the cabin, I also arranged for the folks and kids, except for you to go to my Florida timeshare for the three day weekend. They left last night. We're here to collect your dog Bounder, he's going to be your roomie and training buddy."
Brad led Chad and Max around the back of the house . He let them through the back gate, and closed it behind him. The latch clicked shut.
Bounder came bounding toward them barking happily. He drew up short though when realized it was Brad and Max and a dog instead of his master Chad. He didn't really trust Brad or Max.
"Comere. Bounder, you remember Brad, Max," he said gesturing to himself and Max respectively, then he grabbed Chad by his collar, "and this bitch is your former master Chad."
"Woof?" Chad barked looking at Brad.
Bounder yapped, and looked confused. Brad turned Chad around by his collar. Such that his tail was facing Bounder.
"Sniff, Bounder. Sniff Chad's butt. See it is Chad," Brad said.
Chad felt Bounder's wet nose push against his and scrotum. Bounder couldn't believe it. This funny looking dog is Chad. He buried his nose deeper in Chad's balls, Chad yelped and his red doggy dick slipped out his furry sheath.
Brad laughed. He tied Chad's leash to the nearby gas meter.
He said, "Bounder, looks like Chad os horny for you. Max, and I will give you two some alone time to get better acquainted. Suddenly, Chad heard the hiss of an aerosol, then he felt the sting of rubbing alcohol on his anus and balls. Brad was being extra thorough. Chad yelped louder and growled as he realized the pheromones that Brad just coated his ass with belonged to a female dog in heat.
"Come, Max, we will go inside and get breakfast. Bounder's horny and full of pep, and Chad's tied up and worn out from the park. They should be knotted in no time. See, Max. Chad is so small and tight compared to you and your big cock. Chad's hole needs stretching. After a weekend with his best friend Bounder riding his ass, Chad should be loose enough to take you, Max."
Chad was so focused in horror on Brad's words, he didn't notice Bounder come up behind him until Bounder mounted him. Chad howled. Claws on his back, penis penetrating him and swelling to knot him. Brad had been distracting him on purpose. He growled and shook helplessly. Brad had been watching Bounder moving in to mount Chad the whole time.
"It's for your own good, Karl plans to use you as his personal bitch after you've been trained to obey. And I saw the size of that kid's boner. It's unnaturally huge. I suspect whatever he did to make you a dog. He also did to make his cock grow 3 times its flaccid 5.5"."
Chad could do the math. 16.5 inches? Yikes.
"Yeah, so let Bounder stretch your hole all weekend. Then Max will have you all week."
Chad whimpered. Bounder yapped happily. Brad and Max disappeated into the house. At least Brad didn't video his humiliation.
Oh, wait. Brad had been over last week installing security cameras in the backyard. Chad had questioned the number and placement. Now it all made sense. Brad had at least six cameras focused on Chad the whole time.
