Wthou hassle, Carlos quickly stripped, leaving his little boy parts exposed. The whole classroom filled with giggles as Carlos blushed. After that, Mr. Mendes uttered a spell that would age the 10 year-old at a pace of one year every thirty seconds. The changes soon began.
At first nothing noticable was happening. No one noticed anything until a kid shouted "Look! He's taller!"
And Carlos was, and he felt the class slowly shrinking. He was still barely different, standing at 4'11". He was now 11 years-old. Suddenly, a tingling in his crotch shocked Carlos. He stood up for everyone to see a few hairs around his penis, that were thin but slowly multiplying. It was also apparent that his manhood and balls were slowly getting biiger like the rest of him. His feet ainchesnd hands became bigger than the rest of him. "Wow!" Carlos cried out as this continued for a minute. Soon, he became 13 and stood just over 5'. There was also a bit of hair around his ankles, outlining the size 8 feet, and his dick had grown to about three inches. His body had lost all baby fat, and although he was still small, his body was continually growing closer to Mr. Mendes' height.
Just then, Carlos hit a growth spurt. He shot quickly, growing at about a rate of an inch every eight seconds. Hair began to become noticable on his arms and legs, his hands and feet also expanding. His face matured into the face of a young teenager. Carlos was getting embarassed by thes changes, especially withall of his friends watching.
"Lift your arms so people can see underneath." Carlos reluctantly did so, and the class got to see black hairs appear in his armpits. "Speak." Mendes commanded as well.
"I cAn'T bElieVe tHiS iS hAppEning!" Carlos exclaimed in a cracked voice as his voice changed. The voice caused the class to burst out laughing. Carlos' torso elognated, stretching hjim taller than Mr. Mendes at 5'9". His package had gone through a growth spurt as well, his penis now at 5 inches, the pubic hair around was more curly, and started to peak.
"I'm sO tall nOw!" he exclaimed in a deeper voice that shocked everyone. However, it still cracked and lacked the depth and echo of a real man's voice. Peach fuzz appeared on his maturing face. He compared his old shoes to his new ones, he was about 7 or 8 sizes bigger than before. There, stood a 15 year-old version of Carlos.
The height growth slowed down, only to be replaced by hair and muscle growth. His lanky body filled out, his biceps forward, his leg muscles ballooning, his pecs became defined, and his stomach became a six-pack. He wasn't overly muscular, but he definately wasn't left out in hair. He itched all over as hair thickened on his arms, chest and legs. His pubic hair formed a
trail in the middle of his torso. Mendes asked Carlos to raise his arms again, his armpits had full bushes instead of thin hairs this time. As Carlos felt his face, he felt something scratchy appear on his face "Yes! Stubble!" he shouted in his fully developed voice. This caused him to reach for his neck, feeling his defined Adam's apple. Finally, to finish of the growth, his penis expanded from 5 inches to 7 inches, his balls dropping to their fullest potential. The growth stopped. There stood Carlos at age 18.
Carlos was blessed with a great body. He now stood at six feet tall, had a toned body, talked in a deep voice, had some nice stubble, and a good-sized package. He reddened as he sddenly got a boner in front of the whole class, as he couldn't control his hormones with his still 10 year-old mind.
