Kristy's pussy was tingling, and had been all day, ever since gym class. She had just started sixth grade, and one of the many new things to get used to in middle school was mandatory showering after gym. She had been so nervous, worried that all the other girls would be staring at her and making fun of her body. As it turned out, she needn't have worried. Everyone was so nervous that their eyes remained glued to their own feet the whole time. Ironically, the only one really looking at the other girls had been Kristy herself.
It started as simple curiosity. It was alright if she just looked at her best friend, Amanda, right? She just wanted to see if her tits were as big as her clothing suggested. Just as Kristy had suspected, Amanda's tits were still just small bumps on her chest without any extra padding to get in the way. From there, it didn't take long for Kristy's eyes to start moving down, her gaze passing over Amanda's smooth skin until it was resting directly on her pussy. Here, Kristy was surprised to see a generous amount of pubic hair obstructing her view of Amanda's slit.
That was when she first became aware of the tingling, and she looked away from Amanda, embarrassed. What was happening to her? Kristy knew about sex, of course, but her mother hadn't felt the need to fill her in on the finer details. As far as she was concerned, sex was something that was done for the sole purpose of making babies. She had no idea that it also felt good and was done for fun.
She liked the new feeling she was having, and decided that it might feel even better to look at more people. There was Tiffany, who was rather mature for her age and had sizeable tits and well-maintained hair covering her pussy. And next to her was Kathy, whose undeveloped body still hadn't lost its boyish nature. All over, so many naked twelve-year-old bodies, each one so different from the last.
Just as she had predicted, the tingling in her pussy had become more intense, and she could feel her heart pounding in her chest. Almost unconsciously, her hand was drifting toward her pussy, as if it knew what to do even if Kristy herself did not.
And thenthe bell rang and Kristy had to rush to get dressed and get to her next class on time. She should have just stayed and taken her time though, because she didn't learn a single thing the rest of the school day. She just couldn't focus because her mind kept going back to the scene in the locker room, making her pussy get tingly all over again. There was also something else that occupied her attention: she could feel a dampness in her panties and she was praying to God that no one would notice it. She knew it wasn't pee; her mom had explained to her that it was something that could happen as she grew older, and that it was natural and she should just ignore it. But that didn't mean it would be any less embarrassing if someone noticed she had a wet spot on her crotch.
After what felt like an eternity, school was over and Kristy could figure out what was going on. The second she got home, she ran upstairs and shut herself in the bathroom. She didn't know what she was going to do, but whatever it was would be easier without any clothes in the way.
She started by first just removing her plain green top. She studied her tits in the mirror, mentally comparing them to the others she had seen that day. She was still mostly flat, a slight puff around the nipples the only thing to distinguish hers from a boy's chest. Nothing to brag about, but at least she had something. Next off were her jeans, whose absence revealed a cute pair of pink polka-dotted panties. She noticed a patch of wetness on the front, but nothing major. It would probably dry up soon and then it would be like it was never even there. Then, the panties too were off and Kristy was fully naked. She examined her preteen slit, disappointed that there was still no sign of hair.
Now that she was naked, she let her mind wander back to the showers. Once again she was looking at everyone else, but in this fantasy they were all checking Kristy out as well. Somehow, that made her pussy tingle even more. She let her hands caress her bare pussy, surprised at the wetness she found there. The feelings were getting more intense, but it wasn't enough. She wanted more, but she didn't know what else to do. Maybe...
"What are you doing?"
The voice snapped Kristy out of her trance, and she let out a surprised yelp. She had forgotten to lock the door, and now her little sister was standing there with a confused look on her face.
Beth was nine, almost ten. If you asked Kristy, she was the most annoying thing on the planet. Do anything wrong around her, and as soon as possible she would run off to mom to tell. And now she had seen Kristy naked and rubbing herself.
"I was just using the bathroom," Kristy said.
"Then why are you naked? And touching your... lady parts?" Beth retorted.
Under normal circumstances, Kristy would have found it hard not to giggle at her sister's euphemism, but there was nothing funny about her current situation.
"Just forget about it! You're too young to understand!"
This was the exact wrong thing to say. If there was one thing Beth hated, it was being looked down on because of her age.
"Too young? I'm almost ten! That's only two years younger than you! I can do anything you can do!"
And with that, Beth stormed off to her room. Kristy knew she had to go into damage control mode, or she would be in big trouble. She quickly redressed and went to knock on her little sister's door.
"I'm sorry I said you were too young," Kristy said in the most apologetic voice she could muster. "Can I come in?"
As expected, there was no response. Kristy knew she would have to wait until Beth had cooled off a bit in order to make any progress. And so she just sat in front of the door, waiting.
It was almost an hour before Beth finally opened the door. She knew Kristy would still be waiting; this was a ritual they went through often. Honestly, Kristy was surprised Beth had opened up so soon.
The inside of Beth's room was like that of any other nine-year-old: a complete mess. Toys were scattered across the floor, drawings were stuck in random intervals along the walls. Kristy thought that her mom would kill her if her room ever got this messy. But now wasn't the time to complain.
"What were you doing?" Beth asked again.
Kristy was surprised to notice that she had asked almost pleadingly, rather than demanding the information in return for not telling mom.
"Why do you want to know so bad?" Kristy asked.
Beth blushed and looked away from Kristy.
"Because, I liked watching," she mumbled, ashamed. "It made me feel all... tingly."
That wasn't the answer Kristy had expected. Suddenly instead of just seeing an annoying brat sitting in front of her, she saw a little sister who was confused and scared of the new things she was feeling, much as Kristy was herself.
"Alright. Take off your clothes and I'll show you what I know." Kristy said.
Beth's eyes lit up. "Really?" she asked.
Kristy just started stripping in response, and it wasn't long before Beth joined in. It had been a long time since Kristy had seen Beth naked, but she hadn't really changed much. Sure, she was taller and thinner than she had been, but there was no sign that she had started developing yet. Even so, seeing Beth's body had the same effect on Kristy that watching the girls her own age had. Based on what Beth had said, Kristy imagined her little sister was feeling similarly. Beth looked up at her now, eager to find out what happened next.
"Feeling good?" Kristy asked, and Beth just nodded in response. "Well, to tell you the truth, I don't know too much about this either, but I know it feel good just to hold your... lady parts... in your hand," Kristy said. She had almost said "pussy", but had decided she didn't want to risk getting in trouble for teaching Beth a dirty word. As if what she was already teaching Beth wasn't dirty.
Now, both girls were lying on Beth's bed with their pussies cupped in their hands. The excitement was making them squirm, and the movement only increased their pleasure. Still, there was only so much they could do with that technique.
"Do you think it would feel better if we touched each other?" Beth asked.
"It's worth a shot," Kristy replied.
The moment Beth's fingers touched her pussy, it was like an electric shock passed through her whole body. As luck would have it, Beth had just discovered Kristy's clitoris.
"Yes! Just like that!" Kristy moaned. "Rub there! Faster!"
A whole new world had opened up to Kristy. Feelings she had never thought possible were coursing through her body. Her breathing was fast and shallow, and her heart felt like it was trying to break out of her chest. She felt like she needed to pee, but there was no way she was going to stop now.
Just when Kristy thought she couldn't feel any better, it happened. Every muscle in her body tensed up, and then it was like a wave of pure ecstasy rolled over her. It seemed to last an eternity, and when it was over, everything seemed dimmer in comparison.
"Are you okay?" Beth asked.
The concern in Beth's voice overwhelmed Kristy, and the next thing she knew she was kissing her. Not just the sisterly kisses they usually did to please their mom, but a real, passionate kiss. Kristy wasn't sure if she was more surprised by finding Beth's tongue in her mouth or realizing she enjoyed it.
Eventually, they broke apart, both gasping for air.
"I'll take that as a yes," Beth said.
"Your turn now," Kristy replied, and Beth lay back and spread her legs with a huge smile on her face.
Now Kristy was rubbing her sister, and Beth really seemed to be enjoying it. Her breath was coming in short gasps, and every now and then a cute, high-pitched moan would escape her lips.
It was almost too much for Kristy. Just looking at her sister's face, so contorted with pleasure, was making her tingly again. She imagined what someone would think if they were to walk in right then. Two naked, preteen girls with barely-developed bodies, the older one playing with the younger one's pussy. Seeing a little nine-year-old, whose flat chest was covered in sweat, writhing around, screaming out her pleasure for the whole world to hear.
Then, Beth tensed up, and Kristy smiled knowing what she must be feeling. She could see why Beth had been concerned about her; the thrashing about Beth was doing could easily be mistaken for pain instead of pleasure. When she had settled down, Kristy planted a soft kiss right on Beth's lips.
"Wow," Beth whispered.
"Wow is right. Come on, we should get dressed before mom gets home." Kristy said.
From that day on until Kristy left for college, they spent every afternoon after school like that one. Sure, they both got other boyfriends (and girlfriends) during that time, but the sex never felt as special as when it was just family.
