Joe was in his own room, lifting weights as usual. "Huff, huff..." Joe put the weights down. "Boy, this gets easier every time, ain't that right" Joe flexed his arms, hardened with muscle. He was that kind of guy. A bit of a narcissist, thought he knew well enough to keep it to himself. He looked down to see his dick, which could get a foot large hard. "You're even bigger that Dad's. Don't know what would happen if I lost you."
Lucy was in her room, playing with her dolls. "Stupid Joey!" she said to herself. Her brother was a bit of a jerk. Sure he didn't hit her or degrade her, but he did have a bad habit of making fun of her playing with dolls. "Even though Katie never played with dolls. Why can't he see I'm just different? Daddy does."
Joe was a little down. He was scolded by his parents for making fun of his little sister. "I mean she's almost in middle school now. Don't they stop doing those stupid things?" Joe was asked by his father to apologize to Lucy, which only annoyed him more. Being the perfect son, Dad shouldn't have to make him apologize for such a trivial thing. "This fucking sucks! Argh!" Joe bursts out of his room. "I'm smart! Just need to make Lucy see that she's too old for that shit!" No one else is home right now, so this should be perfect.
Lucy put her dolls down, when Joe burst into the room. "What do you want, Joey? I'm playin'" "What? With these things again?" Joe picked up the doll from the ground. "Hey! Give that back Joey!" " No way! You're gonna be ten in a month and you'll be in middle school. You have to stop playin' with this stuff now." "What do you care Joey. My friends play with them still." "Yeah, right!" "It's true! Katie didn't like dolls, but if you were me, you'd know!" "Oh really?! Not that I'd want to be you any..." Joe suddenly stopped, dropping the doll. "There, that wasn't so hard...... Joey?" It was then Lucy noticed something was wrong with Joe. He clutched his stomach and breathed heavily. "Wow! Is it hot in here or what?" "Hot? The air is on." "Oh... Oh my. Lucy... I gotta... I gotta go." Lucy looked and noticed Joe sweat pants were wet near his pee-pee. "Did he wet himself?" Lucy thought. "Hah! Serves you right!" "Ah, Ah, Ah.... Oh god, Lucy!" Joe sunk down at the door and clutched his pee-pee. "I'm not feeling sorry for you!" Lucy turned her back, thinking this was some act. "Ah, Ah, Ah! Oh boooooy! Lucy. Stay like that! I gotta..." "Ew! Don't pee in my room!" Lucy turned around and saw a horrific sight. Joe's pee-pee was out and was hard. Something white was coming out. "Joey! Gross! Stop that!" "Ahhh, Oh god!" The white stuff stopped coming out. "Lucy... Ah... I'm sorry. I don't know what hap... Ah, Ah, Ah, Ah, Ahhhhh!" More white stuff came out. Lucy realized this was no joke. She moved away. Joe was blocking the door, so she couldn't get out the door. "Oh god! Fuck!" Joe could no longer control himself. "Joey! Joey!" Lucy didn't know what to do. She was in tears. "Lucy, You gotta get hel... Ah, Ah, Ah, Ahhhhh!" "The white liquid came out again. Lucy screamed and hid near her bed, knees scrunched up and her eyes tightly closed. "This has to be a dream! This has to!" Lucy opened her eyes, thinking she would wake up, but then, she saw an even weirder sight...
"Jesus Christ! What the hell is going on?!" Joe was afraid. He was cumming like a mad man and he couldn't control it. "Lucy! Lucy!" He tried calling to her but to no avail. "Dammit! When I get my hands on you, I'll.... Ah,Ah,Ah,Ah,Ah, Ahhhhhhhhhhhhhhh!" Joe cummed again. "Oh boy! When will this end?! Joe looked forward trying to keep his mind of his cock, when he saw an even weirder sight. He saw his pants and boxers on the floor way from him. He must have kicked it off in the struggle. That wasn't what was odd though. His feet were looking smaller, almost dainty like. His toes were shrinking, whatever hair there had receded. His feet went from a size 14 all the way to a size 5. His ankles shrank to accommodate. "My feet! What the hell is going on with my.... Ah,Ah,Ah,Ah, Ahhhhhh!" He cummed again. "Is this... Is this related?! Ahhhh." He cummed again. Lucy heard Joe yell about his feet. Coincidentally, Lucy's feet were doing something as well. Her socks were stretching. Lucy could see her toes poke out, but they had hair on them. *Snap* Her socks ripped apart and her feet kept growing. They became meaty and they looked like Joe's feet now. "Ahhhhhhhhhhhhhhh!" Joe heard Lucy scream. "Lucy! Lucy! What's going on, on, on, Onnnnnnnnnaaaaaaaaah!" Joe cummed yet again. It was as if his dick prevented him from getting help. He clasped his dick hoping it would stop moving. Then his hands started to change too. Again the hair on his knuckles receded. He tried to keep his hands on, but they became too small and his hands slipped off. Cumming again, it hit his face. "Blegh! Shit!" Joe looked up and his hand looked like a little girl. Lucy was touching her now manly feet in panic. She then felt her hands stretch. Hair grew on her knuckles. Veins pulsed and meat formed. Her hands were like a man's as well. More cum. At this point Joe was used to it. It was the changes in his body that fascinated him. Looking at his hands again. He saw his wrists shrink to compensate. His arms lost its muscle mass. Joe had to move his eyes to see his arms which shrunk into his body. The small wisps of hair dissipated. "My muscles! My beautiful muscles!" Joe felt like crying, but his dick wouldn't allow it. He cummed forcing his eyes open. They rested on his legs. Like his arms, they too lost their muscle mass and moved towards his pelvis. The last of his body hair vanished. His pelvic area shrunk to compensate. And again he cummed. "Good god! Ahhhhhh!" "Joey! Joey! I don't feel good now!" Lucy knew her pleas were in vain, but she needed to hear her voice. Her arms and legs had grown to massive proportions. She was getting hairy. Her pants had already snapped off. And her panties ripped open with her pelvis growing. Luckily Joe couldn't see. "Ah, Ah, Ah, Ah, Ahhhhhhh! Ahhhh!" Once again he cummed his attempts to reach his dick were futile as his arms were to short, but he was actually getting closer. Joe watched in horror yet again as his body was shrinking. His pecs were spreading out on his skin and he was completely flat. His abs were next. Each one compressed on his body. He could get near his dick again, but he cummed again as if to laugh at him. His dick hurt like hell now. He knew if he touched it he would cum. "My body... My body's gone... I must be getting younger! It has to be it. Ahhhhhhhhh!" Joe cummed and he watched. Then he saw his belly button come out. "An Outy! Oh shit!" Joe realized it now. Lucy's shirt was practically in shreds. Her body was growing as her hands went away from her feet. Her stomach felt tight and she saw 8 square shaped masses jut out. Her breast, well what little of it, actually grew, but it only became square shaped. "This body..." Lucy felt she knew this body and then her belly button sunk in becoming an Inny. "Wait! This body is...." "Lucy's!" Joe realized it then and now. He cummed again and he felt his face scrunch up. "Ahhh! AHHhhHH!" The pain stopped quickly, but he knew he must look like Lucy. "It makes sense now. All my cum is leaving my body. Lucy doesn't have this yet," Joe thought to himself. Lucy felt a horrible pain in her face. "AHHhhhHHHhhhhh! It hurts! It hurts Joey!" The pain stopped suddenly and Lucy knew her brother's face had replaced her own. Joe heard Lucy's scream. "Don't worry Lucy!" Joe told his little sis. "It will all be over so... Soon! Ah,Ah,Ah,Ah,Ah,Ah,Ah,Ah,Ah...... Ahhhhhhhhhhhhhhh!" Joe let out one last ejaculation, his scream becoming womanly. This was the longest of all. His dick got less harder and went flaccid again, but it didn't stop shrinking. "Oh no! No,No,No,No, Nooo! Joe tried in vain to stop it but his dick went back in his body. His balls followed suit and swirled into his body becoming the small vagina of a girl. "Joey!" Lucy heard his pleas as she felt a burning sensation in her pelvis. Lucy watched in horror as she saw two scrunchy ball like objects came out. Then something like a mushroom with a pink, fleshy stem. It came out like a snake. Lucy saw her new pee-pee come out and get almost harder. The mushroom part pointed at her face and it started to shake. Lucy, having seen what she saw before, covered it as she in rapid unknown puberty cummed for the first time. "Ahhhhhhhhhh! Ahhhhhhh! Lucy let out a loud yelp as her voiced dropped in tone. The white stuff stopped and her new pee-pee went back to normal. She wiped her hands on the floor. Joe felt relief for the first time. He got up, being careful not to slip. In a daze, he went to where Lucy fled to and saw they unthinkable. He saw his body scrunching its legs and feet like a girl. His body was touching its dick in wonder. Lucy was in a daze. Scared she looked at her new pee-pee and touched it. Lucy looked up to see her naked body looking down. "Jo....ey?" Lucy eked out. "Lu....cy?" Joe did the same and then.... "AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!"
