Matt whimpered frustratingly. Why did his masters get such amazing rubber suits while he was left practically naked? Don understood. He wagged his tongue out of his muzzle excitedly and prepared to make a wish.
"I wish Matt would get an extremely girly slave suit similar to ours." His rubber tail (which was a copy of the wand) lit up with blue magical energy.
First, a pink chastity device appeared and encircled his small puppy dick. The device attached to him and automatically locked itself in. Matt knew it could only unlock itself through the masters' magic. Slaves had no use for their dicks anyways.
Next, shiny pink liquid latex was crawling up his skin. Soon, every corner of him was covered with in bright pink. A black collar with his new name, "Sapphire", was written in glittery rhinestones. A 10 inch dildo gag inserted itself into Sapphire's pink rubber muzzle. Slaves had no reason to speak. Sapphire would never be able to use her voice again.
Finally, the suit made some adjustments to Matt's already girly body. Her arms and feet became paws, and her back bone structure changed to make her permanently quadrupedal. Next, her arms, legs, and waist thinned considerably while her ass and hips ballooned out. She even started to grow a pair of small, but round black latex breasts. They hung down and bounced around as the new femboi doggy Sapphire tested out her new legs.
Don and Billy smiled. They were now a perfect family of anthro rubberpups. Two strong alphas and an obedient sex slave? What should they do next?
