Ric snatched the book away from Josh, but he'd already finished his recitation.
"What did you do, you little punk?!" exclaimed Ric, panicking.
"Nothing much, 'big brother'," said Josh, a little smugly.
Ric had no chance to respond as the effect of the spell began to take hold. A huge wave of sexual pleasure coursed through Ric's young body, bigger than anything he'd had a chance to experience. He moaned in pleasure, and his voice cracked. He stumbled back into a nearby chair, and grunted, his voice now in a higher register. He was dimly aware of his clothing now loosening around him as the sensations escalated in intensity.
Josh, meanwhile, was feeling something similar, but he was better able to control it, it seemed. His perspective changed, slightly, as he grew several inches. His baggy clothes became rather tight, especially in the crotch. He rubbed his cock, which was bigger than he was expecting. It felt more alive than the young boy could remember.
When the changes finished and the incredible sensations cleared away, Ric stood up, clutching his waistband to try and keep his pants from falling.
"What did you do?" he asked, shocked at his new, higher pitched voice.
"Isn't it obvious?" said Josh, his voice now some degree lower in pitch, though by no means deep. "I swapped our ages. Heh, little brother."
"What? Why?" said Ric, feeling close to tears, despite himself.
"Because your attitude sucked, bro."
"And how does THIS change things?" Ric said, motioning to himself.
"Welll... I did make one other LITTLE change...," said Josh, slyly.
At that moment, little Francis stepped from behind the now larger Josh to investigate. Ric looked at Francis as though for the first time. Indeed, Francis was now only slightly smaller than Ric, which made a considerable difference, or so he thought.
Ric stared open mouthed yet again, but this time for a very different reason.
"Oh wow, he's beautiful...."
