... And here's the two unlucky souls. In the house of six, there were only two. The older sister Kate was busy texting with friends while the youngest child and son John was watching cartoons. "Up to anything?" one of Kate's friends asked. "Nothing much. Just relaxing with the little bro." "Oh, how cute! *lol*" "*lol* Watching cartoons again?" the other asked. "Yep. He's so lucky being the youngest. Gets the whole house to himself sometimes." "Jealous? *lol*" "Maybe I am. *lol*" "I bet you'd like to switch places with him too! *lol*" "No way! *lmao*" That was what Kate said, but deep down she wasn't that against the idea, impossible though it was. Suddenly John got up. "Hey Kate. Could you pause the show. Need ta use the potty." "Sure thing." Kate did just that as John got up to go to the bathroom. "Hey John?" Kate hesitantly asked. "What?" "This is a silly question, but what do you think if we could switch bodies or something." Kate had no idea why she asked. Something almost compelled her to ask. "Hee,hee. That is a silly question. But I guess it would be kinda cool to be the big sibling. I'd get to boss ya around!" John joked around "Oh really!" Kate joked back. The two shared a small laugh and John made his way into the bathroom. "It was a weird question to ask." Kate thought to herself.
A few minutes passed and John came back from the bathroom. "Thanks. You can unpause now." "Sure thing." Kate took the controller and pressed the play button, but then that's when it happened. "Katie? I said you could unpause it." "That's strange. I did." Kate pressed the button a few times, but the TV remained paused. "Must be something wrong with it." Kate got up to do it manually. She and John made their way towards the TV. And then that's when something even stranger happened. Smoke started coming out of the blu-ray player. "What?" "Careful!" Kate moved John back, thinking something was on fire. But the smoke was white and odorless, like mist. It swam around in the air unnaturally. "Katie?! What's going on?!" "I-I don't know!" The smoke continued it ascent and wrapped itself around the two. Even stranger things started to occur. The smoke was lifting the two of them up. "Kate?!" "John?!" They tried to fight it, but the smoke was too strong. Their held hands were torn apart, leaving the two flapping in mid-air. "Katie?! What's happening?!" John asked again. "I told you I don't know dummy! Wah!" The smoke then flipped her parallel to the floor. "Kate?! Whoa!" The same thing happened to John. And there was more to the weird happenings. The smoke wrapped around their bodies more pulling off their clothes. "What the fuck?!" "Katie?!" Kate was freaking out now, even cursing in front of her little brother. Each piece of cloth came off easily, exposing their bare skin to the cold until John was only in his Superman undies and Kate in her white bra and panties. Kate could feel the clasps of her bra come undone. "No! No,no,no! Stop!" But to no avail as they fell off her body. All that was left was their undergarments and just as easily those moved off their bodies leaving them completely naked.
The smoke moved their bodies up right with their feet level with each other. Kate's breasts, a decent C-Cup, flopped up and down slightly, while John's penis, still that of a boy, did the same. They now had full view of their naked bodies. "Ahhhhhhhh!!" They both yelled out. John covered his tiny dick and Kate tried desperately to cover both her breasts and clitoris. "Katie?! What's happening?!" "How many times do I have to tell you that-" But before Kate could finish her sentence, she noticed something. "Hey don't stare at me!" "John, you're eyes?!" Kate removed her hands to point at his face, no longer caring what he saw. "My eyes?! What about my eyes?!" John touched his eyes to feel if there was anything wrong also letting his sister see his baby penis. "They're no longer blue. They're brown!" "What? Brown... Ah! And your eyes are blue, not brown! And your hair is moving back into your skull!" "My hair is changing too?!" John watched as his sister's long hair jutted back into her skull turning from blond to pitch black. As this happened, Kate watched John's hair do the exact opposite. His hair moved out and down his back. "Ah!" John felt it and grabbed for his hair. "My hair! Why's it blond?! Why's your black?" "My hair's black?!"
Kate's mind immediately went back to a few minutes ago when she had asked an innocent and silly question. "No way!" "What?!" "No fucking way!" "What?!" Before Kate could answer, John could see her moving closer to his eye level, but she wasn't moving, rather she was shrinking. And from Kate's perspective John was growing. "We're actually switching bodies!" "What?! That's..." John wanted to say impossible, but he looked down. He was indeed growing taller. His tiny feet were moving towards his sister. They remained thin, but a red coloring was growing on his toes. Kate likewise looked down to see her feet moving into her body. Her red nail polish was disappearing. Her legs moved into her stomach as they got a little fatter, while John's legs grew outwards losing his baby fat. "I'm really growing! No way!" "And I'm shrinking. No! Our legs and feet are no each other's Joh-Ah!" "Kat-Ah!" They looked towards each other and then they noticed. They were at eye level!" "Kate!" "John!" They called out to each other as they passed each other in height. Kate now had to look up at her younger brother. "Katie! Katie! Agh!" John eyed his entire body as it continued to grow. His arms and hands followed his legs and feet in growing. His chubby little body was thinning out quite nicely and though it was small, he could see a bit of abdominal muscle sticking out. His outie hollowed out into an innie just like his sister had. "John! John! Hngh!" Kate felt her body getting weaker by the second. The skin in her arms retracted into her body which was also getting smaller and fatter. She felt the skin in her outie puff out into an innie, something John had not a second ago. "This can't be happening! Ah! My voice!" Kate was too mesmerized by the changes in her body she failed to notice the change that had proved she was switching bodies with John. "Ah! Katie! Your face! Ah!" Kate heard John yell out in a much different voice, but it was one she knew well. She slowly looked up to see John rubbing his throat, but his face was no longer there. Kate was starring at her face. John looked up to see his own face where his sister was starring at him. "AHHHHHHHHHHHHH!!" They both yelled.
"We really are switching bodies Katie!" John exclaimed as he looked at his sister. Her body looked like that of a little kid, but that with huge breasts unfit for their body. And from Kate's POV, she could see herself. Only the tiny penis swinging side to side proved the person in front of her was once a boy. And then it happened. Kate could see John's pectorals sag a bit and become formless. His nipples darkened as they jutted out of his body. Soon two circular pieces of flesh were visible. John was growing honest to god boobs. "Katie! What's happening?! My body feels so heavy. "Shit!" was all Kate could say as a pair of C-Cup breasts fully formed on John's body. They flopped up and down as John flinched. Slowly he cupped them in his hands and touched his nipples. "Ah! Ah! What are these? Ah! They're so... ah! Sensitive! Gah!" As he continued to play with them, his nipples hardened and became erect. "Stop touching them!" Kate yelled out unable to take John playing with himself. "I'm-I'm sorry!" John dropped them. Kate finally looked down at her own body as her breasts were shrinking into her body. "No! No,no,no! This can't be happening!" Kate grabbed at her breasts to keep them from sinking in anymore, but to no avail. Her nipples lightened in color and she couldn't feel any pleasure from them. Her breasts spread out on her pectorals as they became flat as a board. Only her clit showed she was once a woman.
"Ah! Ah! Katie! My pee-pee feels funny!" Kate looked towards John. "God!" was all she could say. John's dick was fully erect, something unthinkable for a child his age. Though it was only like five inches tall, it pulsed as if he was about to ejaculate. But before long it started to get smaller. But still erect it was pulling back into his body. His balls followed suit as they sucked into his pelvis. "Gah! Agh! Katie! It hurts!" Kate continued watching as John's penis shrank until only his head was sticking out. With a plop, it vanished completely. "Hmph! Gah! Katie! Make it stop!" At John's tears, Kate snapped out of her trance. "D-Don't worry Johnny! It's almost over!" "Almost?! What's left?! Ahhhhhhhhhhhh!" John let out a yell as he grabbed his stomach. Though she couldn't see, Kate knew his cock and balls were forming into his uterus and ovaries. "Katie! I don't... feel so good! My tummy!" "John..." "Ah! Ahhh! Katie! Katie! Katie! Ahhhhhhhhhhhhhh!!" Suddenly John let out a yell as his body shook. From his vagina, a wet, sticky liquid shot out onto the floor. "Holy shit!" The pain must have been too arousing as John was ejaculating. His first as a human was as teenage woman. "Ah! Ah! Ah! Sniff! I'm peeing..." John let out, his thoughts unfiltered.
"John..." Kate looked solemnly at her brother, well sister. But before she could comfort him, she felt the insides of her body burn. "Ah... Ah... Ugh...!" John, still squirting out jizz, looked up at his sister. "Katie..." "Ah! Oh god! It's happening John!" Katie grabbed onto her stomach as she felt her uterus was on fire. A mix of pain and pleasure was plastered over her face. Losing control of her bowels, she started to cum as well. "Oh god! Jesus!" "Katie?!" Kate ignored John as she felt her uterus fall down inside of her. Her ovaries followed suit as she felt them rest over her clit. "Hmph! Hmph!" Kate let out two short grunts as two flesh shaped sacks of skin fell out of her clit. They soon filled with two balls, very tiny, but still undeniably there. She stopped cumming as another dull pain was rubbing on her clit. "Ah! Ah! Oh god! Here it comes!" "Katie?!" "Ah,ah,ah! John! Johnny! I can feel it! Ah! My... My... pee-pee!" As soon as she said those childish words a mushroom shaped object pushed out of her hole. It soon was followed by a stem shaped piece of flesh. "Agh! Gah!" Kate grunted as her new dick grew out. She didn't have to wait long, as at three inches it was fully out. Unlike John, her penis stayed flaccid. "Gah!" Kate let out one more grunt as she felt her body relax once and for all.
As soon as it was over, the smoke moved their bodies once more. Not even bothering to put back on their clothes, it let them down back at the front of the TV where it all started. Once their feet touched the ground, the smoke let them go and went back inside the blu-ray player... And then silence. Both John and Kate, panting heavily, slowly looked towards each other. After a slight pause, John was the first to open his mouth "Well... Looks like I'm the big sister now!"
