It was a normal day for a father and son. They were simply minding their own business, when the son John, a nine year old boy, said something strange. "You know, I wish I could be a Daddy!" "Huh? Ah,ha,ha! Where did that come?" the father Bob, a 35 year old man, asked. "Well me and my friends were talking about our Dads and it just sort of came up. Thought it was cool." Well, there are cool things about being an adult, but a kid like you should be a kid for as long as you can. There are some uncool things about being an adult." "I know, I know! Just was thinkin' is all!" "Well I do wish I could be a kid again sometimes too, so I see what you mean." "Hee-hee! Then maybe I could be your Daddy!" "Ah,ha,ha! It would be interesting to be your son!"
Then, all of a sudden, Father and Son felt a shock between them. "Dad..?" John asked his father inquisitively. Something more felt off. His mind felt slightly disconnected from his body. "John..." It was all Bob could do in reply. He felt the same. His more developed mind felt it more strongly. It felt like he wasn't supposed to be an adult. He felt like he was supposed to be John's age. His dick twitched. "This is silly," Bob thought, but as soon as he did, his body shook. John's body shook in return. "Dad?!" A look of fear crossed John's eyes. His body felt warm. "What?!" Bob asked himself incredulously. He felt a chill. Then it happened. John was starting to get bigger.
"Dad?!" John shouted out. It looked like his Father was shrinking. "John?!" As Bob watched what should have been impossible, John continued to grow. But it was more then that. John looked like he was getting older. His face was losing it chubbiness. The creases in his clothes were starting to even out and stretch across his body. His stomach started to peak out from his shirt. He looked like a preteen now. "Daddy! What's happening?!" John could hear his voice was a little deeper as his father continued to shrink. The five o'clock shadow was fading from his face as his tighter clothes started to loosen and drape. His sweats were slowly starting to droop off his waist, the bottom started to cover his bare feet whose hair was sinking back into is skin.
"John?! Ahh!" Bob could only repeat his son's name as he watched him get older. He was now in his early teens. His stomach was now fully showing and the bottom of his pant legs were creeping upward. John's penis was starting to really show itself as a bulge as well. It looked no bigger then five inches now. "Ohh... Ahh!" John moaned as he grabbed onto his growing member. He could feel it getting harder in his hands. "Oh my god!" Bob thought to himself as his own eight year old son was now sporting a massive hard on. "Dad... My pee-pee feels funny! Ahh!" John shook once as a wet spot formed in his pants. He could feel a surge of some white, hot, sticky liquid come out his pee hole. He instinctively knew he wasn't peeing. The word ejaculate came to mind, even though he never heard the word before. He looked towards his Dad for reassurance. He looked so much younger now. He had seen his Dad in marriage photos and he looked just like that now. His pants were soon about to fall off and no sooner had he thought that, it did. His shirt was draping over his body even more, covering his modesty. The tops of his toes shrunk back inwards until his downed pants were covering them up. The body hair on his legs were receding and getting less muscular.
As John stopped cumming, his erect dick got softer, although it was still pretty visible in his tight pants. Soon after, they were starting to tear all over the place. Bob could see the changes affecting his body. A little body hair there, a little bit of more toned muscle here. John looked like a high school jock now. His Adam's Apple was more visible then ever. "Daddy?! Daddy!" John called out to his father with a much deeper voice. As he continued to grow more, Bob realized something even more horrific. "My son is at my eye level! Holy crap!" "Dad?!" John looked in horror as he could see eye to eye with his father and then he had to looked down. He looked like his college photos that John had also seen. His shirt was hanging off his body even more now. One sleeve dropped over is arm. The bulge near his shirt suck up and out. Bob felt the raging hard overcome him. The full force of perfect virility he hadn't had since his early college day came at him all at once. "Oh god! Agh!" Bob's body shook once as it was his turn for a wet spot to form on his clothes. John watched as drops of a white liquid fell from his shirt to the ground below. "Ah,ah,ah! Oh god!" was all Bob could say as he let the ejaculation run its course. As it stopped, his dick shrunk back down.
John could feel his tight clothes start to tear even more. A few seconds later his shirt ripped in two and his pants soon after. His underwear held tight, but both of them could see the dick head sticking out. "It's so big!" John thought to himself. Bob could only watch in a a mix of shame and amazement as his son was now undeniably an adult. But as he looked closer, something else was familiar about the body in front of him. The shape of his body, the amount of body hair, as Bob squinted, he could even see a birthmark appear over John' growing pectoral muscles. "No way!" "Dad?!" "John, you look like me!" "What?!" "No way! This can't be happening!" John watched his panicking father continue to shrink and then it was his turn to see something familiar. His Dad looked like a preteen now, but as he got even younger, the final shape of his transformed face took on a familiar look. John blinked a few times in shock. He didn't want to believe it, but he couldn't deny it. It was the same face he looked at in the mirror for months now. "You look like me Dad! Ah?!" John told his father what was on his mind and out of his mouth came a familiar voice. "I what?! Ah?!" Bob replied and what came out was also familiar. "I sound like you!!" They both yelled out.
John grew a little bit more as a five o 'clock shadow grew over his face. Bob shrunk a bit more, his face getting chubbier. The horrible feeling soon faded. John looked at his father. His huge shirt draped over his entire body, One shoulder blade was just holding it up, but the body was undeniably John's. Bob looked at his son, his grown ass son. Miraculously, his undies were just holding on, although that did little to hide his monster cock, one that Bob knew; well had known quite well. John was the splitting image of Bob now. The two looked at each other with a mix of shock and uneasiness. They couldn't quite say anything, lest they accept what really happened had happened. "Ah..." John was to first to open his mouth. Not quite sure if he should scream or faint on the spot, he let out the first thing on his mind. "Guess I'm the Daddy Now!"
