"The truth is, my awful step brother, that you're nothing but a rat."
Dustin's eyes widened in horror as his body began to tingle and itch madly. "N-no! Please! Don't make me a rat, Ty!"
Slowly, Ty approached Dustin in the shower. He was starting to get a fine covering of fur over his skin, but it wasn't his lost puberty
returning. He was growing fur. Ty stood in front of the trembling Dustin, noting they were roughly the same size - perhaps Ty was taller
now, he grinned inwardly - and he watched as Dustin fell and gripped the side of the tub.
"Tyyyyyy...." Dustin groaned. "Please." He looked over his agonized and hairy body and let out a cry as his face began to crackle. His ears
began to grow. A tail began to stretch from above his back. "Nooooo!" Dustin gasped as he broke into a warm sweat. He was now almost
totally covered in brown rat fur.
Ty watched Dustin's painful changes and felt a rush of power and arousal. He said nothing, did nothing, just stood and watched his step
brother devolve from a human being.
Now Dustin shook violently and collapsed onto his hands and knees in the tub, his long rat tail curling out behind him as his face pushed
longer. He was halfway between a human and vermin when something else started to happen - Dustin was shrinking! Though he couldn't
have known, so lost in wretched pain that all of his senses were numb.
Now Ty's excitement had turned to full blown arousal as he watched Dustin become smaller. The rat boy was totally inhuman and looking
more like an animal with each passing moment. The process was fascinating to watch. As was Dustin's furry body lessening.
At last, over half his 'original' size gone, Dustin the rat rose with difficulty on disproportioned back legs and huge clawed feet, and realized
there was a serious problem as he stared up at Ty's knees.
"Look at you. You're so small now. So helpless. I bet I can pick you up."
Dustin squeaked in alarm, speech lost to him, as Ty reached down and easily picked up the still shrinking and terrified rat. "Wow." Ty
gasped. "So small." He reached up and brushed the now totally animal's back, feeling the rough coat of brown fur, and switched the
squirming Dustin to one hand as he shrank small enough, nearly done. The rat began to protest in Ty's grip, struggling, squeaking in fear.
Ty clenched his hand tighter and grinned as Dustin let out a pained cry. "You're still in there, aren't you?"
The rat paused, then nodded slowly.
"Good." Ty grinned maniacally. "I wanted to make sure you can enjoy this."
And with that, he willed Dustin into the sewer. The rat in his hand simply vanished. Dustin was gone.
