All of the little kids in the room are chatting excitedly about what happened to Kimberly. Next to you, John was practically bouncing on the balls of his feet like he was all sugared up.
“Did you see what happened to Kimmy? She just got boobies out of nowhere?” he said, sounding rather hyper.
“Yeah,” you said, trying not to give away what you did. But with the wand tucked underneath your desk where no one can see, you contemplate your next move.
You decided to change John. As a teenager, he was a handsome, muscular jock, but now he was just a hyper, fidgety, gap-toothed kid. You waved your wand at him from under the desk.
Suddenly John stood up and all eyes in the room turned to him. He was breathing heavily. You watched as his clothes tightened: his muscles were coming back. Or at least some; you wanted him to remain proportional.
The little boy’s shoulders and back widened, and this broader back filled with knotty muscle. Meanwhile, thick pecs pushed outward, nipples facing down, and 6 perfect abs were carved into the boy’s stomach. His arms swelled with biceps like tennis balls, while his legs doubled in size, filling his pants and shoving his butt out into a shelf. Finally, a prominent bulge became visible in the boy’s jeans. Through all of this, John’s clothes stayed intact- barely. The cartoon T-shirt outlined every contour, as did the now-tight jeans.
In awe, the class burst out chatting again, while John flexed his muscles with excitement. “Look at me!” he cried. “I’m so big!” He turned and tried to lift up the teacher’s desk. Even with his muscles he was struggling, but with a wave of your wand you made John super-strong. Now he lifted it with one hand. “I’m so strong!”
But now John started to get an erection. Like you, he was a little boy with an adult libido, but unlike you, he didn’t remember having ever been old enough to manage his penis before. You could see his eyes glaze over as he moaned with sexual pleasure, panting as he struggled to remove his jeans.
Finally he got them off and you saw the 6-incher in his undies. John shot a load, then passed out on the ground. Shockingly, no one made fun of him for wetting himself. Instead, several went over to feel the unconscious boy’s huge muscles.
