"Keith? Is that you?" Damian asked as he went downstairs. "Who? Who are you? What are you doing in my house?"
"Your house?" Keith replied. "Aren't you too young to have your own house?"
"Well, my parents are not here. So, I'm the one in charge." Damian tried to sound imposing.
"What about your brother?" Keith started to grin. "Shouldn't he be in charge because he's the oldest?"
"He came out." Damian replied. "Besides I don't need him, I'm more mature. He acts like a child."
"Oh yeah? Well, If you're so mature then maybe you need to look like one too!" Keith smiled.
"What are you talking about?" Damian said before he was zapped with keys. An intense light blinded him as he started to feel hot and his clothes started to feel uncomfortable.
He opened his eyes and was about to yell at them when he realized that his shirt felt super tight on him now. He looked down and noticed that his shirt had shrunk. He could see his stomach peaking out from the bottom now.
"What? Did you shrink my shirt?" He didn’t know how his shirt could shrink so quickly. "Ooooh ooh" He started to feel really funny now. He heard his clothes beginning to strain. Damian finally knew what was going on. Somehow, he had started to grow.
"He-he-hey, Ugh!" Damian was confused as he felt his body starting to stretch all over. He felt himself start to grow taller. At the same time he felt his shoulders starting to stretch out. He could hear his shirt beginning to rip open all over. His arms started to become longer and larger. His muscles got more defined and lean as he matured rapidly. Damian’s shirt couldn’t take much more.
He can feel his pants getting tighter and tighter. Damian quickly unbuttoned his pants to make room for his growing waist but suddenly he felt his feet starting to stretch and grow larger inside of his shoes. Keith and you noticed that Damian's body started to sweat rapidly, he was so hot due to his body’s sudden growth spurt.
Damian’s shoes began to tear open, he wiggled his toes as they started to stretch out of the front of his shoes. He looked down at his body and saw that he was so much bigger now. He couldn’t help but flex his body’s growing muscles causing his shirt to rip clean off his body. His sweaty torso was now exposed showing off Damian’s matured muscles.
"Ahhh!" He felt his feet continuing to grow and stretch out of his shoes. He continued to stretch taller causing his pants to strain even more. His thighs grew thicker followed by his legs growing larger.
"Uuuhh!" Damian groaned in pain as he felt his face mature through 15 years of puberty in a matter of seconds. His face became more structured and masculine, and surprisingly hair started to sprout from his cheeks and chin.
You were so focused on his maturing face that you forgot about the rest of his body until we heard a loud rip and immediately looked down and noticed that his pants were now destroyed. He looked down at his new manly legs and saw that his shoes were completely shredded. He moved his large size 14 feet and wiggled his hairy toes to convince himself that those were still his feet.
He slid his hand down his newly defined abs, pecs and biceps as he felt the new hair that had grown on them too. He felt some new tingling sensations starting to occur as he did this. It was a weird and tickling new feeling.
Damian was so distracted by his new body hair that he didn't notice that his balls started to drop inside of his tight underwear. It wasn't until they were so big and heavy that he realized it, but he closed his eyes trying to ignore the new growing need to hold them. However, he couldn’t resist any more once his dick started to lengthen in size.
"UH!! UH!!" Damian slid his large hand inside of his tight underwear and rubbed his thick balls and cock. He started to stroke with pleasure.
"Oooh! Hah! Th-this isn't right it feels soooo good!!" Damian moaned with a big smile on his face. He kept moaning as he leaned against a wall to stroke his large cock. The now 27 year old hairy man was enjoying himself so much that he didn’t care that he was being watched by Keith and you.
"AHH! UH!!" Damian let out a loud moan as he came all over the carpet under his big feet. He was sweaty and hot all over. He was extremely confused and tried to understand what has just happened to him. Suddenly he heard a loud laugh from the boys staring at him.
"Aww, looks like you're not as mature as you thought! Masturbating in front of two boys. You could go to jail because of that!!" Keith said as he laughed. "Come on. Let's go upstairs. The mature man needs some space to think about his behavior and clean the mess he has done. It's disgusting!"
Keith holds your arm and you two went to his bedroom. Meanwhile, the now 27 year old Damian tried to balance his new body as he thinks what to do now.
