Karen was happy. Her body had finally started to develop. At this point she still had no hair around her pussy but her chest, instead of being flat, now had tiny breast buds poking out. They were nothing compared to her 14 year old sister Lori's or 13 year old sister Ashley's but Karen was only 11. Some of her friends had already started to develop but many still had the body of a six year old.

Lori, Ashley, and Karen all shared the same room. Karen had looked with envy at her sisters longing for the day she would "become a woman." Many nights she would fall asleep rubbing her flat chest. A friend had told her such action would "help her grow" so she faithfully followed the suggestion.

Being the youngest, Karen always found herself last. When she played with her sisters, it was always Karen who would be the baby if they were playing house, if playing tag, the first to get caught. Her sisters weren't mean about it but they were always faster, stronger, taller, or somehow ahead of Karen. There were advantages though. There was always an older sister to stick up for her. An older sister to help her. All in all, the girls seemed to get along very well.

Karen was proud of her newly developed tits. She had been waiting for a comment from one of her sisters congratulating her but so far neither had said anything. Karen almost wanted to blurt out "Look what I've got!" but was much too shy. She remembered her sisters talking about their own chests when they first developed. Now that Karen had something, she wanted desperately to engage in an "adult" conversation with her sisters.

One night, as the sisters were doing homework, the two older started a conversation. "Did you hear that Mary is going in for another operation?" Lori began.

"You're kidding! She's already had four," Ashley commented. Karen had no idea what her sisters were talking about or who Mary was.

"Actually five," corrected Lori. "All because no one noticed her problem."

"I know. If only they had found out. One little pill instead of all those operations," continued Ashley. "I'm glad I had you to check me." The last comment caught Karen's attention.

"Well, if it hadn't been for you seeing my problem and me getting one of those pills, I could be going through the same thing Mary is," added Lori.

Karen was now a little more than curious and somewhat scared too. "What problem?" she asked.

"Oh nothing," Lori dismissed. "It's just something girls have to watch out for when they start to develop. You've got nothing to worry about."

 Karen became nervous. Hadn't her sisters noticed her development? Could she have a problem? "What?"

"Some girls don't grow right," Ashley explained. "Lori doesn't like to talk about it. If they find out soon enough, they just give you a pill. If they don't, they have to keep operating until everything is fixed."

"I've started to develop," Karen blushed.

"Oh," Lori commented. "Are you OK?"

"I guess so," stammered Karen.

"You guess so?" questioned Ashley. "You don't know?"

"Do you know what to look for?" Lori asked.

"No," mumbled Karen nervously.

"Do you want us to check you?" Ashley offered. Karen nodded.

"It's kind of embarrassing," Lori told Karen. "You're going to have to take your clothes off and we're going to have to look at you."

Karen thought for a moment. The idea of having her sisters examine her might be embarrassing but it was better than going to the hospital for operations. "OK"

"Take your clothes off and get on the bed," Ashley said to Karen.

Karen nervously stood and stripped to her panties. Her sisters seemingly ignored her as she climbed onto the bed. "I'm ready," Karen offered.

Lori and Ashley looked over. "You're going to have to take your panties off too," Ashley said.

"Oh," Karen commented as she slipped them off. The two older sisters walked to either side of the bed. "Stay still," Lori instructed. As she did, she reached out and started to feel Karen's tiny breast bud. Karen blushed but remained motionless. Lori, finishing with one side, moved to the other. "Seems OK to me but you'd better check too,"Lori commented to Ashley.

Ashley repeated Lori's movements, pushing and squeezing Karen's mounds. Karen shifted some. The pinching of her sensitive mounds proved a little uncomfortable. "Does that hurt?" Ashley asked. Karen nodded. "Oh..." Ashley mumbled.

"What?" Karen questioned. Had Ashley found something?

"Ah, nothing," Ashley answered. She looked up at Lori with concern. "We'd better check the rest." Lori nodded. Karen began to get more nervous. "Open your legs," Ashley told Karen.

Karen spread her legs opened. "This is the part I hate," mumbled Ashley. "You're not going to like this, Karen, but it has to be done." With that, Ashley's hands went to Karen's bald pussy and her slit was pulled open. A flush came over Karen's face. Ashley bend down and looked closer. "I think it's OK but you'd better look too," Ashley told Lori.

Ashley stood up as Lori's thumbs went to Karen's pussy lips. Karen felt herself being opened again as Lori bent down. "Open more," Lori instructed. Karen, wanting Lori to be sure, moved her legs further apart.

Lori studied the prone girl's pussy for a while. "It looks OK from the outside," she commented. She shifted her hand until the pussy lips were being held open with only one hand. With her free hand, Lori extended a finger and started inserting it into the gaping hole.

Karen, feeling the invasion, jumped and snapped her legs closed. "What are you doing?" she exclaimed.

Lori stood up with an irritated look on her face. "I think she's had enough, Ash, Let's just forget it and see what happens!"

"No. We can't do that," Ashley answered. She then looked down at Karen. "We've got to check the inside. If you don't want to, it's OK," Ashley explained to Karen. Karen didn't answer but slowly reopened her legs. This time Ashley's hands went to the exposed pussy. She carefully opened the slit and Karen felt a finger slip inside.

For the first time, something was in Karen's canal. She had assumed that something entering her would hurt but it hadn't. She could feel her sister's finger moving inside her. It felt strange. Unconsciously Karen's legs parted more giving the visitor more room. She stayed motionless as the digit slowly turned inside her. The experience was actually quite pleasant. Karen was disappointed when the finger pulled out. She then felt a small jolt at the finger moved to the top of her slit.

"What did that feel like?" Ashley asked.

"It tingles," Karen answered.

"Good," Ashley commented as she bumped Karen's clit again. Karen felt another jolt. The feeling of humility was being replaced by a new feeling of pleasure. Ashley's finger slowly slid around Karen's slit.

The sensations Karen was feeling were new to her. She didn't understand them but wanted more. Slowly her eyes closed as her mind concentrated on the sensations emanating from between her legs. She had been told to stay still but her body had to move. Her hips began to shift and her ass lifted from the bed pushing her crotch into the hand between her legs.

Karen's breathing quickened and became ragged. Her knees bent and flopped down on the bed opening her legs even more. Moans were coming from deep within her almost like someone else was making the noise. Her hips were rotating, keeping rhythm with the finger moving up and down her now wet slit.

The presence of her sisters had completely left Karen's mind. Every cell in her body was concentrating on the sensations being produced between her legs. She had never experienced this kind of pleasure. Every stroke of the finger seemed to increase the pleasure even more. Her body was writhering uncontrollably. Her feet were planted firmly on the bed pushing her hips against the finger causing the intense shocks traveling throughout her body.

Suddenly there seemed to be almost an explosion in her crotch. Karen's breath sucked in as waves of pleasure radiated from her pussy. She knew she was making noises but had no power to stop them. Her stomach muscles quivered as her hips pushed her sopping wet pussy up. Her ass was suspended in the air. Karen's body had taken control of itself away from her mind. Her chest heaved as her lungs fought for air.

After what seemed like hours, her mind regained control over her body. The sensations between her legs subsided and her body fell back onto the bed. She was finally able to catch her breath. She had no idea what had just happened but it was the best thing she ever experienced.

"I think she'll be fine," Karen heard a voice say. A smile came over her face. She might be OK now but she knew she'd need a lot more checks to make sure there were no problems.
