Note: This story was dynamically reformatted for online reading convenience. I'm Tom. I'm 10 years old and live in a small suburb on the outskirts of London. I'm about 4'4 and I'm in year 5 in school. All of my friends are boys, and to be honest girls really annoy me. Unfortunately though, a girl in my year, Darci, has to sleep round my house, (in my room!) tonight. Darci is in my class at school, is about an inch shorter than me, and has light brown hair in a ponytail. She arrived at my house at about 7, and had only been inside for a few minutes when mum came in and said, 'Right, your father and I will be out for three hours. We expect you to be at least in your pyjamas when we get back. I've locked the door so you won't have to worry about your safety. Have fun!' With that she gave me some money for pizza, and went out the door. Me and Darci sat awkwardly, looking absent-mindedly at the tv. 'So,' Darci said, 'Howre you?'  I glanced over to the 10 year old, who was still wearing her blue school polo shirt and grey pleated skirt. She was, actually, quite pretty. I wondered why, when me a lot of boys were together, we called them gross and ugly. We're old enough to know they dont have germs or anything like that, so why do we have such a thing against them? '...Tom?' Darci interrupted my thoughts. I was so startled that I just blurted out, 'Yeah.' Darci looked at me, puzzled. After being asked how I was, I just replied with a simple word, and it didn't make sense. I tried to recover it, 'Sorry, I'm fine, how about you?' The preteen smiled at my screw-up, and replied,  'Im good thanks, so, what're we gonna do tonight?' 'I dunno really, what do you want to do?' 'Do you wanna talk about boys and girls?' I shrugged, and looked at Darci, willing her to elaborate. 'Well, we say the names of our friends and talk about them. Pretty easy really.' 'Okay,' I said, 'You go first.' Darci nodded, and glanced down in thought, before talking about her various friends. I soon grew in confidence and started talking about my friends too, and eventually we were bitching and laughing about our friends and the people we really didn't like. I found myself wondering again why boys are so repulsed from girls and vice versa. Darci was a genuinely nice 10 year old girl. I started to feel strange feelings for her that I'd never felt before. We were both only children, and our school had no sex ed classes or anything like that, so we were both completely clueless about each other. I just felt really happy around Darci, and I hoped she felt the same. The talk about friends had dried up a bit, so I started talking about more human things.  'Hey Darci, do you know what a boys body is like?' She giggled, but soon regained her seriousness. Darci was very grown up for a preteen, and didn't have a laughing fit whenever anyone tried to be serious with her. I liked that, because I always thought I was a lot more serious than my friends.  'Well, no, not really. I mean, girls have longer hair... Isn't that it?' I basically thought the same. 'But,' I said, 'Why would we have to change in different rooms?' She thought about that for a moment, then said,  'Well, why don't we find out? Shall we play doctors?' I wondered whether it was worth it, because I knew there must be something fundamentally different between boys and girls, and I wasn't sure that I wanted to find out. In the end, I just went for it and agreed, as long as she went first. After a little more giggling, Darci agreed with my offer, and asked what she had to do. I told her I think she should take her clothes off, and she giggled again. Originally, in class, I found her giggling incessant and annoying. As she was giggling in front of me though, I found her smile very cute, almost... sexy. I smiled at the thought of finding a girl sexy, but then Darci began to take off her polo. I couldn't take my eyes off her as she pulled her blue shirt over her head. She stood infront of me, her flat chest on show. The 10 year old has slightly tanned skin, which was completely flawless around her chest. She had a cute little belly button, which dipped slightly into her pretty stomach. I looked from Darci's chest to her face, and she had a beaming, slightly embarrassed smile on her face. I nodded for her to continue, and she complied, and slowly pulled her long white socks off, showing her bare legs that were a similar shade to her chest. Now the preteen was only wearing her skirt, which she then started to pull down, making sure not to pull her knickers down at the same time. She slowly removed her skirt, moving down her bare legs and dropping it to the floor when it reached her knees. She looked at me again, and smiled.  'Well doctor,' she said, grinning, 'Is there anything wrong to report yet?' I smiled back, 'No, none yet, Miss Darci, nothing apart from your clothes and hair. But, there is one last piece of clothing still on.' Darci giggled at my doctor impression, and continued taking off her knickers. She slowly slid them down her legs, then I saw why boys and girls were different. Just after she dropped her knickers to the floor and stood for a second, I said, 'Hey, where's your dick?' She giggled, and replied,  'Whats a dick?'  'Well,' I said, 'Its er, where I pee from.' Darci looked at me, and said,  'Well, I pee from my pussy!' I guessed her pussy was the hairless slit between her legs, her pure hole of girlyness.  'Can I touch it?' I asked 'Not yet, doctor, you agreed to show yourself too!' 'Oh yes, sorry nurse.' I said, blushing. I quickly took off my my shirt and socks, and pulled down my trousers, only leaving my pants.  'Is your dick under there?' Darci said, inquisitively. I nodded, and then slowly pulled my pants down. I then stood in front of my preteen friend, both of us completely naked.  'So,' Darci said, 'You pee from there?'  'Yeah,' I replied, 'Its easy 'cause I can do it standing up. Can't you?'  'Well I guess I can, but it's a lot easier to sit down.' I asked the 10 year old if she could show me, and she said that she was actually really desperate for a pee, so we walked upstairs and into my bathroom. The room was really big, because we had an extension put it and we had no other use for it other than the toilet. The toilet itself was right in the middle of the wall, so someone observing could have a good view of the side of the toilet. The naked preteen rushed in and sat on the seat, and waited just long enough for me to get into place near her pussy. She then opened the taps, and a small stream of pee flowed from her slit. It was a really weird sight, as the steam was a lot less powerful than from my dick, and it lasted longer and hit the water in the basin straight away. After about half a minute, the stream stopped, and Darci stood up. A small droplet of urine dripped from her pussy, and landed on the floor. Other than that we were in silence.  'Hey Tom,' Darci said, 'do you need a pee?' I nodded, as since I'd seen and heard the pee streaming from my friends pussy, I'd been needed a pee as well. I grabbed hold of my dick and positioned it over the toilet. Darci kneeled down next to me, and watched as I pissed into the basin. She looked at me, shocked that girls and boys were so different. After I stopped, she giggled loudly.  'Oh Tom. That's so weird! Why do you think were so different?'  'I dunno,' I replied, 'let's go on the Internet and find out!'  Darci liked that idea, and we spent the next 5 minutes searching what a dick and a pussy did. We were shocked to see that they were used to have sex. Some people even said that people fucked with them. Of course, we were curious, so we talked about sex.  'What do you think it feels like?' Darci asked. I shrugged, and said that I read that boys and girls have to be aroused first.  'Oh yeah, I saw that,' Darci said, 'apparently girls have to rub their pussy.' I agreed, and asked if I could do it. Darci giggled, and agreed. I told her to sit down on the sofa, and I moved up to her pussy. I took my index finger out, and moved it over to her slit. I carefully pushed it in about a centimetre, and she shivered all over.  'Ooh Tom,' the preteen said, 'That felt weird!'  I took my finger again, and rubbed it all the way up her pussy, and she shivered again, I took my finger to my nose and smelt it, expecting the strange liquid on it to smell of pee, but it didn't. I licked my finger and it tasted good, so I moved my head over to Darci and took a big lick up her pussy hole. I got a big mouthful of her strange juice, and it tasted really sweet and salty.  'MMM, Tom that feels really good! Do it again!' I complied, and licked her up and down. Her pussy was very moist now, and my dick was hard, I didn't realise when it had happened. According to the website we were looking at, that meant we were aroused.  'Darci,' I whispered, 'We're both aroused, do you want... To fuck?'  'Ooh, yes Tom, you licking me felt so good, I want to make you feel good!'  She lay down, and spread her legs. I positioned my dick at the entrance of her pussy, and I pushed it in, breaking through something. Darci burst out in pain, but we both knew this'd happen, because her hymen was breaking. I didn't know about Darci, but her pussy was very tight and wet, and felt amazing round my dick. I began to push with as deep thrusts as I could. Soon, Darci's cries of pain had become cries of pleasure, and she was bucking her hips in time with my thrusts. I looked down at the 10 year old, and saw her pretty preteen face locked in a state of complete bliss. I felt blissful too. I was pushing in and out of her pussy without even thinking about it. I could feel something building inside me, but I didn't know what it was.  'Mmm, Tom, this feels so good, and it's getting better Tom, oh god, fuck me, please!' I couldn't believe what I was hearing. Darci was asking for more, and I was giving more. Soon, I felt Darcis pussy convulse and tighten around my dick, and she cried out, 'Oh god! Tom, somethings happening! Fuck, fuck! AAAHHH!'  The preteen screamed as her 10 year old pussy exploded in it's very first orgasm, and soon I joined her, as my dick erupted in preteen orgasm, and I felt a stream of hot sticky liquid flood her pussy. I kept thrusting until my dick had shrunk and Darci had subsided. She stopped moaning, and when we both calmed down, whispered, 'Oh fuck Tom, that felt so good. I love you Tom, I'm gonna tell all my friends to fuck anyone they can.' 'Me too! Let's fuck anyone we can Darci, so we can compare friends in a different way!' She agreed, then fell asleep under my naked preteen body, and I soon joined her.
