Nick sat between Peter and Ty, trembling in fear. Was he crazy? It wasn't possible to become a little boy. But here he was, almost naked and dwarfed by the teenage boys around him. One of the boys, the one called Peter, grinned and put an arm around Nick's shoulders, giving him a gentle hug. "Don't worry, little guy. We aren't gonna hurt you. Hell, I was your age just a few hours ago."
The former police office blinked up at the muscular, well-hung teen. "Huh?"
Ty patted the boy's head. "Yeah. We won't leave you stuck like this. Maybe." He reached down and pinched Nick's small penis gently through the speedo. "Not much there. That what's got you worried? I can fix that."
Nick had gasped and flushed when Ty groped him, but was afraid to do anything to resist. Then his mouth fell open and he arched back against the seat as a wave of incredible pleasure and warmth shot through him. When it finally faded, Nick felt a slightly uncomfortable pressure between his legs and looked down. The speedo was stretched out away fom his crotch, an 8-inch uncut cock and testicles the size of walnuts spilling out of it. His eyes widened and he felt the huge organ. He shaft started pushing out as it got even longer with erection. "That's impossible!"
Ty and the other boys all laughed. "Dude, that's nothing!"
Peter looked at Tye. "You know what would be fun on the beach? A big, dumb, happy dog to play frisbee with. I think this kid would make a terrific Irish Setter. He already has the red hair."
"What?! NO!" Nick squirmed suddenly trying to get out from between the boys. But he was wedged in the car and Ty only had to start patting his head. "Settle down, fellah. Be a good dog. You can run and play on the beach when we get there."
Nick suddenly felt confused. He wasn't a dog. Was he? The speedo vanished, and his huge cock and balls changed. His cock turned pink, and his foreskin thickened into a sheath that attached to his belly. A dog's dick and balls. A furry belly. As he watched, his chest barreled out and his legs and arms became the legs of a dog. Looking up, he caught his reflection in the rear-view mirror. He was an Irish Setter with the head of a red-haired boy. As Ty kept patting his head, his face pushed out, his skull shrank, and his thoughts got simpler. As the blue human eyes became liquid brown eyes of a dog, Nick the boy's intelligence and memories changed, becoming the instincts and memories of a happy young Irish Setter, going to the Beach with his masters.
