I was 13 and this is true
It was a Friday night and my sister was bringing my friends sister home from school. She was 13 and she had brown hair and brown eyes she was very cute. She went to the same school as my sister and her uniform was a skirt and a purple shirt. So we were at my house and my sister and her friends had gone out. It was only me and her in the house so we were just watching TV and I was sitting next to her on the sofa. I was going through puberty and I got regular erections. Unfortunately I got One. I had the remote on my leg and the adverts came on so she (lets call her M) leant over and tried to get the remote so did I and I ended up pushing her hand into my rock hard erection. She new a lot about sex for some reason. M said 'you've got a boner haven't you' I blurted out NO! Straight after she said yer right and slowly started moving her hand up my leg into my now growing erection. She grabbed my dick and started to rub it through my trousers with her soft small hand.
She looked really horny so I leant over and she moved towards me we snogged for about 30 seconds until I said come with me. So I ran up stairs into my bedroom. She pushed me onto my bed I was really horny. She moved her hand toward my dick and pulled my pants down to my knees. She pulled my dick out of my boxers but then said 'wait. I will get you REALLY hard' she went over to my office chair and started taking her shirt off. She started to rub her pussy through her skirt. She started dancing and then took her skirt off and threw it at me. She was then only in her panties and training bra.
She had smallish boobs but I don't really care. Then she started to rub her pussy so I couldn't help but start to wank. Then she took her panties off and threw them at me. She crawled over the bed and lay on top of me she then started to fuck my knee and I snogged her and played with her boobs. She then rolled onto her back and started panting after a minute. She hadn't orgasmed.
I then lay on top of her and rubbed my rock hard dick against her throbbing pussy. After a minute or two we both orgasmed at the same time and I snogged her really hard. We kissed and pleasured each other for about an hour and a half. We have snogged every time we were alone. I replay this moment over and over in my head.
