A Sisterly Swapping

added by Anonymous 3 years ago AR AP BM S Magic

And thus the story of two brothers who swapped bodies, lived each others lives and came to an understanding about each other has come on end. The two would live out the rest of their lives with nothing special happening to either of them. This would make for a boring story of course, but luckily this world has no shortage of interesting stories to tell. In fact, there was one that was only talked about in this very story. Yes, this is the story of a girl who switched bodies with her older sister. As you know, the young girl was Lisa. Her sister's name was Alexandra. This was their story.

Going back to ten years ago, a seven year old Lisa was fuming. Her sister Alexandra always had everything she could have wanted. Even though she was the youngest, Lisa didn't seem to get any of her parent's love or attention, or at least not any noticeable one. That would be bad enough, but Alexandra was always very rude to her. At eighteen years old, she acted like more of a child than Lisa was. Today was another day of Lisa trying to live her young life and Alexandra treating her like dirt. "Well not anymore!" Lisa shouted to no one in particular. Lisa finally decided to put her foot down. Some one had to be the adult here. She stormed the way up to her sister's room. "And then I said!" Lisa could hear her talking to someone. One of her shallow friends no doubt. "Not that she ever brings them over," Lisa thought to herself. She took a deep breath and then went in. "No freaking way! Lol!" "Hey, Alex! I need to talk!" "Ah! Jesus, you scared me! Anyway, can't this wait? I'm on the phone." "No it can't!" "Well it will have to!" Alex put her cell phone back to her ear. Becoming even more annoyed, Lisa grabbed the phone away from Alex's hand. "Hey!" "Sorry, but she'll call you back!" Lisa said to the person on the phone and ended the call.

"What the hell, Lisa?! Is that anyway to treat your big sister?!" Alexandra yelled. They haven't even started talking and already Lisa was pissed. "Oh please! If you want me to treat you like a big sister, then maybe start acting like one?" "What's that supposed to mean?!" "Oh you know! You treat me like dirt. Mommy and Daddy treat you like you're special, but you're nothing but a bully!" "Well, aren't you something!" Alex replied back and got up trying to assert her dominance. "Like you even know the first thing about my life! You would never understand!" "Wha...?! Don't... don't make me look like the bully here!" They were about to really start going at each, other when a sudden chill came over the room. "What... was that?" Lisa asked. Alex looked around the room. "Good... Good question.. Umm... Huh?" "What is it?" Lisa looked at her sister quizzically. Alex was squirming. "What the heck?! I can't... move my body!" "What?! Don't be silly!" Lisa went to walk up towards her sister, but found out that she couldn't move as well. "No... No way... Alex?" "Lisa? Um... well... whoa!" Lisa watched as her sister moved her arms to the bottom of her shirt. "Can you move now?" she asked. "Nuh... No! My body... is moving on its own!" Lisa watched as her sister took of her shirt. "What?!" Suddenly Lisa's hands started to move on their own as well. "Huh?! Wha?!" Like Alex, Lisa took of her shirt as well, leaving her upper half naked. "Lisa?!" "Alex?! What's going on?!" Lisa started to freak out even more. Tears welled up in her eyes. "Don't... Don't ask me! Whoa!" Whoa!" Suddenly, the two siblings started to move, once again completely against their will. "Ah... Agh..." Alex struggled to regain control. As she walked, she lifted one leg and pulled the sock from that leg's foot off. She lifted the other up and did the same. "Ah... Alex!" Lisa also struggled to control her body. Like Alex, she lifted one leg up, but being barefoot, she only had her pants to pull down. As she did so, Alex moved to unfasten her skirt and watched as it helplessly fell to the ground. She was no only in her bra and panties, but that soon was to change. Both her hands moved to her back and near her bra buckle. "No...! No!" Alex's pleas were to no avail, as she undid her bra and let her D-Cup breasts flop out. "Whoa!" Lisa made an O face as she saw her big sister's breasts up close. They were almost the size of her head. Alex and Lisa's hand moved once more to their groin. Their fingers hitched onto the tip of their panties. "Ah!" "Crap!" Both siblings yelled out as they took their panties off, leaving them completely naked. "Oh my god!" "Alex! We're naked!" "No shit!" As the two struggled to comprehend what was going on, they passed each other. A spark was felt between them as they moved forward only to turn around. And when they did, things only got even weirder.

"Ah... Oh..." Lisa watch as Alex heaved several times. Her face was flushed red. "Alex?" "Ah... Oh... Oh god?!" Alex squirmed. She squished her legs together. It looked to Lisa like she was about to pee. "Ah,ah,ah! Oh god! Oh god!" "Alex?!" "Lisa?! Oh god! Ahhhh! Don't look! Ah,ah,ah!" But Lisa couldn't help but look. She could see a liquid fall down her legs. "Ah! Ahhh! Lisa! Lisa, I'm gonna... gonna!" "Alex?!" "AHHHHHHHHHHHH!!" Alex jumped up and pushed down on her groin. A mysterious liquid then discharged from under her. "Ah... Ahh..." Alex's face became even more red as she continued to cum onto the floor below. It ended up lasting for over a minute. "This... This isn't normal!" Alex thought. Eventually, after she felt she had cummed her insides out, she finally stopped. "Oh god! That was awful!" "Alex?! What was THAT?! That wasn't pee, was it?!" "Oh... Oh god! Lisa, you don't even wanna...! What?!" Alex looked down and Lisa followed. She immediately knew what was wrong. The mysterious liquid was coming off of the floor and moving towards Lisa. It swirled around and then went under her. "Ah... Ah..." "No way..." They couldn't believe their eyes at first, but Alex's cum was now entering Lucy's vagina. "Ah...AHHHHHHHHHHHHHH!" "Holy shiiiiiiiiit!" Lisa could feel the liquid enter her insides. She could feel her ovaries and Fallopian tubes change. She felt something inside her break and she could see blood trickle down her legs. "Ahhhhhhh! Ahhhhh! Alex?! What's happening to me?!" "Lisa! Oh... Ah..." Alex could feel her own insides start to change. Her hymen reformed as her ovaries and Fallopian tubes go through a change of their own. "Ah... My genitals... Are they getting younger?!" Alex couldn't believe that, but that was definitely what was happening. The rest of the cum went into Lisa as she heaved once. "Ohhh... Alex..."

Alex looked at Lisa. As she did, she could have swore she was getting taller. "What?!" As a matter of fact she was. "Lisa?! You're growing!" "What?! Ah! Alex?! You're shrinking!" "What?!" Alex looked down as her eyes started to get closer to the floor. She could see her toes fall back into the heels of her feet. Not only was she losing height, but her whole body was getting smaller. Lisa looked down as well. The distance between her eyes and her feet were growing. The skin on her feet elongated as they grew out. She wiggled her growing toes. Her arms and legs stretched out. Her hands got bigger as she gripped them. Her growing nails dug into her skin. Alex's arms and legs compressed into her upper body. The nails on her hands were moving back as her hands got incredibly tiny. Her upper body pushed down. Her skinny body fattened up a bit, as her stomach dropped. Her huge breasts were looking even more pronounced on her tiny body. Lisa's upper body was growing. The excess fat on her upper body vanished as her skin tightened up. As her chest area expanded, Lisa's nipples perked up. They felt incredibly sensitive. "Ah... Oh..." Lisa watched as the small mounds of skin underneath her nipples grew out. The excess skin sunk down and bent Lisa's body down. Her breasts were forming as they grew into the size of D-Cups. "Holy shit!" Alex looked down and saw her own breasts tingle. They started to sink back into her chest. The sensations caused her nipples to get erect. "Ah... Jesus!" Her breasts continued to shrink as her chest are flattened up. Then finally, they felt an intense pain hit their faces. "Ughhhhhh! Gugggggghhhhh!" "Ahhhhhhhhh! Alecssssssssh! It hwurts!" Eventually the pain subsided. They felt incredibly lightheaded and struggled to keep consciousness. And then whatever was causing them to move let them go. They fell to their knees and then finally fainted. They were now each other.
