"Geez Dad! You stupid..." 8-year old John lay down in his room lamenting his situation. His Father, Bob, had grounded him for his failing grade on his test. "I really tried my best too. It was just too hard." John was a smart enough kid, but the pressures to be like his intelligent and handsome older brother Joe and his weak-willed demeanor made it hard to both have a healthy life and focus. "Geez Dad! You stupid..." John repeated himself. It was the only thing he could say while his dad was in the shower. "If only..." John got up from his bed and sat at the edge. "If only he could be in my shoes. Maybe he could see why this is hard for me."
"Oh boy, John..." 35-year old Bob was taking a shower lamenting his situation. He had grounded his son John for his 55 on his test. Bob knew that John probably hated his guts right now. "I get why he's upset... Maybe I have been pushing him too hard... But I want him to succeed in life." Bob himself wasn't perfect back in his childhood either, but he trained himself to be better and it was easy enough. "If anything, its harder for me at work than it ever was." Bob finished washing his hair and turned off the shower. He was a well built man, with nice 8-pack abs and a cock of respectable 6 inch length flaccid and 11 hard. "A good body indeed, but sometimes that isn't enough. If John could be me right now, maybe he could see how important it is to be more confident."
Oh, how little did these two know. That they would get their wish. "I guess grounding him may have been too much. I should apolo..." But before Bob could finish his sentence, he found himself losing balance and falling. "Eh? What the hell?" Bob tried to get up, but could only move enough to lay upright. "Shit. Why can't I move?" Bob tried in vain, but couldn't do anything. This wasn't good. Beside John, no one was home yet. And then it got worse. "Ah... Ah,Ah,Ah..." Bob started convulsing and his body getting more hotter. "Shit... Ah,Ahhh... A seizure?! Ah,Ah..." Bob looked up to see his dick erect. The heat and convulsion made it that way. His dick shock and soon he cummed. "Ahhhhhhh.... John! John! Help!"
Meanwhile in John's room. "Hmm.. Was that Daddy I heard?" He was about to get up, but then clenched his heart. "Ah... Ow... Wha?" He felt his body heating up. "Ah.... Ahhhh! It hurts." John tried to move but fell from the bed, tears in his eyes. Soon his body started convulsing too. "Ah... Ah... Ah,Ah,Ah,Ah... Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!" John let out a load scream that Bob heard. "John?! John! Shit! Him too?! Have we been poisoned or something? Ah,Ah, Ah,Ah,Ahhhhhhhhh!" He cummed again. "Jesus Christ! Oh my God!" More cum, but now there was something else going on. Bob watched as the hair all over his body receded. Even the hair on his balls. The cum slid off, no longer caught in hair. "What? What kind of poison does this?!" Bob then saw his feet. They were shrinking. His toes became less meatier. His size going from 13 to 10 to 7. "What the fuck?!" He cummed again. In John's room, he continued to shake. "Daddy... Daddy... " Stretch, stretch... John heard a sound coming near his feet.He looked and saw the weirdest thing. The fabric on his socks were spreading. Soon his toes started to poke out from its confines and his socks ripped right off. His feet, they were growing. They went from 7 to 10 to 13. Hair appeared on his meaty toes. "Huh... Whaza?! Ah,Ah,Ah,Ah..." Bob continued to struggle. "What's happening?! Why is my body shrinking?" His legs and arms were next. His prized muscles were deflating before his very eyes. His arms and legs were retracting. He could hit his bare feet on the shower, but now could no longer reach it. He cummed. "Oh god! How many times will the happen?!" John continued to struggle. He found that he could move slightly more and could at least get up on all fours. Stretch, Stretch... That noise again. John looked down. He saw the fabric in his clothes, specifically in his arms and legs stretching. They burst apart and saw he was gaining muscle. He was gaining hair. His body was growing. Bob couldn't stop cumming. By now the bathroom was covered in it. And there was more to come. Bob watched in horror as each pack of his abs deflated. His pecs followed suit. Those erect nipples ceased. And his torso began to shrink. He was starting to look like a teen and then a kid. He then noticed something even stranger. A birthmark appearing on his abdomen. "This mark... My son... Ah, Ah, Ah, Ahhhhhh!" He cummed once more. Stretch, Stretch, Stretch. That sound. It could only come from John's torso now. In tears, John watched as the last of his clothes snapped. His body looked like that of a teen and then an adult. He saw his flat body inflate like a balloon. Pectorals formed and he saw his nipples become larger. Hair came out from his armpits. His stomach cramped and saw 8 square shapes form on his body. Right near his birthmark, but that was fading away. More cum. "This is ridiculous. Am I turning... into my son?!" Bob then felt his face scrunch up. "Ugh... Ow! Shit! My fawce!" Bob obviously couldn't see what was happening, but knew his face must be turning into his son. The pain subsided. "Christ! Now I look like my son with a huge dick. Ah,Ah,Ah,Ah,Ah, Ahhhhhh!" Once more he cummed. John was next. "My face! My fawce! Help, help, Ow, Ow!" The pain in his face subsided. John reached up to his face with his now meaty hands and clearly felt it was bigger. More ragged. Back with Bob. "My hands are so little now. Guess all that's left is... Ah,Ah,Ah,Ah,Ah,Ah... Ahhhhhhhhhhhhhhhhhhhhhh!" Bob cummed once more, his final scram becoming higher in pitch. It was bigger than all the others and as it continued he watch in horror as his pelvis shrunk.His balls no longer with hair shrunk and became kind of scrunchy. His 11 inch dick was the last to go. As it cummed it went back to 6 inches still hard, Then 5, then 4, then 3, the 2... The cum stopped though he was still leaking and his dick was no longer hard. "Oh god. Its over." Bob said now in John's voice. Back with John. He had stopped crying, having gotten used to these sensations. Stretch, Stretch... "Eh... What else?" John looked down and saw his Barney underwear was stretching. The fabric tore apart and let his small pee-pee brake free. John felt vibrating in his pelvic area and he convulsed only there. His balls started to grow. The folds of skin stretching apart and hair appearing in great volume. "Ah,Ah,Ah,Ah,Ah,Ah..." John continued those fast moans as his pee-pee started getting closer to his face. From 2 inches, to 3, to 4, to 5, then to 6. It kept growing, and as it passed 7 inches, John's dick started to go up straighter and harder It came up to almost a foot now and the convulsion increased. "Ah,Ah,Ah,Ah,Ah,Ah,Ah... Ahhhhhhhhhhhhhhhhhhhhhhh!!" Having hit puberty at an unexpected rate, John's new dick had no choice. The cum hit his face and the floor. "Ahhhhhhhhh!!" John yelled out more, his voice becoming lower in pitch. And then everything thing stopped. John fell down. "Oof..." John laid there for a couple of seconds and started to get up. He felt all around his body. He moved up to a mirror in his room. "Dad...? Daddy...? Ah... Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!" Bob got up himself and found something to balance himself up to the mirror. In his reflection he saw his son's face."Shit..."
