"I had noted that men and women have different shapes. Men are bigger and stronger and women are softer and more gracile." Jeanie said. "But those characteristics are visible until they reach their mature age. Kids have similar properties."
"I think you're right in some way..." Marcus said. "I've heard of parents who raise their children without looking at their gender."
"So, when do men begin to look different to women?" Jeanie said.
"I think when they hit puberty..." Marcus said a little awkward. "Some of my school friends had hit it, they become taller and stronger, hairier... It's like a sudden growth spurt."
"Oh! Like these!" Jeanie said and she snapped her fingers. It made a popping sound and a cloud covered Marcus for a second. When it cleared, a guy around 16 years old could be seen where the 12 years old Marcus was. He still was only wearing a loincloth, so his legs, arms, chest and back were at sight. His larger frame made his legs to stretch and he was lifting up his bigger bare feet. He looked like a regular teenager with a few muscles and a little bit more of hair on his legs, some on his pits and a thin treasure trail. On the other hand, he was taller than average guys at that age.
"Whoa! What was that?!" Marcus said but he stopped when he heard his deeper voice. "What have you done to me?!"
"Well... you said men begin to change when they hit puberty, so I made you hit it." Jeanie said. "You was right. You definetely are a foot taller than before and I can see some muscles and hair too." Marcus began to feel embarrassed. "But you're not as muscled or hairier as other men."
"Well, puberty hit at different moments and in different ways." Marcus said. "Some get taller, some others stronger and another ones hairier. Some guys get all at their first years but some others didn't."
"So, do men get their bodies at random?" Jeanie said.
"Not exactly." Marcus said. "In school, I've learnt about something called hormones, testosterone for men and strogens for women, their amount decides how much development they get."
"Oh, and how do you collect the testosterone?" Jeanie said. "Does it comes from a tree or in some food?"
Marcus knew the answer but he was red in embarrassment, he put his hands on his knees and crossed his legs making his feet touch themselves.
"Please, tell me!" Jeanie said. "I want to know!"
"Ok... ok" Marcus said and after a long sigh he continued. "Men produce them with his balls..."
"Balls?" Jeanie said. "Do men have balls? Like footballs or basketballs?"
"No! no no no!" He said. "They are more like eggs..."
"So, if they are eggs why do you call them balls?" Jeanie said. "Uhmm.... I think I'll get it better if I see yours! Can you show me?"
"Whaat?!" Marcus yelled. "No! Definetely no! I don't want to show my balls in public!"
"Come on! It won't take too long and I going to make that anybody care about it." Jeanie said. "So, where are they?"
Marcus didn't answer. He kept his sight at the loincloth which was hidding his package. He was completely embarrassed of revealing it, but he should accept that he was a little curious of look at its teenage member. In that moment, he felt a little shake coming from it. It was new to him and he had no idea what was that. Jeanie looked how he was looking at his loincloth and then it shook.
"Oh! You have them there!" She said and then she snapped her fingers, Marcus loincloth began to vanish but, in order to don't reveal his package, he covered it with his hands. "Oh, don't do that! I can't watch your eggs!"
"I'd told you I don't want you to look them!" Marcus replied.
"Ok, so if you won't take off your hands, I'll make this!" Jeanie snapped her fingers again and then Marcus arms separated from his body and fell on the bench. Under his shoulders just remained his small amount of armpits hair.
"What the!! Why did you do that?!" Marcus yelled. "I don't have arms!"
"Don't worry I'll attach them to you in a moment." Jeanie said. "Now, I can see your balls!" She saw that on Marcus groin were three things, a meaty tube and two spheres under it. They were covered with some hair, specially on the tube's base. It wasn't big, maybe two or three inches and the spheres weren't too big too. She was expecting something as big as a football or a basketball or even an egg. "So, do these balls make your testosterone? You should have too much because they are small."
Marcus was completely red in face. These package was bigger than his old one but it was too average that it didn't surprise Jeanie. "Ok, you had seen them. Now, give me my arms back!"
"Ok" She snapped and Marcus's arms returned to their original position. "But I'm not satisfied. If I expect to learn about testosterone I'll need bigger balls!" She snapped again and Marcus's balls began to pump like balloons.
"What?!!!" Marcus yelled. "Don't do that! Stop! Stoop!"
Jeanie snapped again and Marcus's balls stopped growing. Now, they looked like basketballs. His average penis now looked too small over those monsters.
"They are... too big..." Marcus moaned.
"But they are not working!" Jeanie said. "Come on, basketballs! Begin to work!" She put her hands on them and use her
magic to acelerate their hormone process. Marcus felt a warm sensation and began to sweat. He was feeling too much arousal that he firmly grabbed the bench and planted his bare feet on the floor. His body began to grow, he became taller and muscles started to developed around all of him. His thin legs grew until they were like the ones of a professional soccer player, his arms were as big as the ones of a professional weightlifter and his back, chest and shoulders looked like the ones of a professional football player. His feet and hands became bigger and bigger until he broke the bench with his hands. Also, he can feel his feet growing through the floor. His neck became thicker and a ball was growing inside of it. His face became squarer and then hair began to grow on his jaw. Thick hair grew on his arms and legs too and a dense coat covered his massive pecs. Bushes were emerging from his armpits and his previously subtle treasure trail began to thick until it connected with his chest hair. His pubes thick too until they look like a wild mess. Hair grew on his balls and an itching on his butt made him assume he was growing hair there too. Finally, his small and average teenage dick began to grow pumping like the balls did before until it was a foot longer.
Marcus was completely aroused that his long pole get hard and shot a big load of cum which fell some feet away from him. He stayed immobile for some seconds until he recovered from his arousal.
"Wow! You're right. Testosterone makes men to grow!" Jeanie said happily. "You're huge now!"
Marcus panted for some seconds before he speaks.
"That was intense!" He said and then he realized his voice was a deep baritone. "My voice! My body! I'm a freak!"
"Don't worry I can turn you back in a snap!" Jeanie said. "But before that... I was wondering... what's that?"
She pointed at the cum Marcus had shot before. He became red again but he knew that he can't be more embarrassed than now.
"It's called cum." He said. "It's men seed which contains their DNA, I guess."
"DNA?" Jeanie said. "That's what makes men to be men, right?"
"I think so..." Marcus said. "Can I turn back now?"
"Of course!" Jeanie said. "But first I need to see you in more details!"
