This happened to me last saturday, Jo and I are both 14.
Hi, I'm 14 and before last week, I didnt know what masturbation was, but then my best friend Jo showed me how!
We usually sleep over at each others houses every couple of weeks, last week we were at her house and we spent the day in her pool. After spending three hours in the pool, her mother came out to tell us that Jo's parents were going out for dinner, only we were being looked after by her (very hot!) brother, Nick.
Things went normally for the next few hours, we showered, had McDonalds for dinner, and sat around in Jo's room watching movies, with Nick in his room. We were watching a movie with heaps of sex scenes (I cant remember the name) and we were both a bit shy, but as the movie went on, it was alright, but as I looked over about an hour in, the blanket over Jo seemed to be moving. At first, I thought she was scratching, but it lasted ages, so I asked her what she was doing, she went all wierd, but I kept asking her and 10 minutes later she gave in and said she was 'jilling'. I asked her what it was and she couldnt believe I didnt know.
She eventually believed me and removed the blanket from over us to show her soaking wet panties. I stared at her as her fingers made their way down her stomach to her cleanly shaved vagina. I copied what she was doing, and could feel that I was getting wet as well.
As she was starting to dance her fingers around her eager pussy, she starting moaning, I tried to copy, but it was doing anything. I told her that it was doing nothing and she smiled, took her hand from herself and slowly crept it down my stomach to work her magic. As soon as she had her fingers there, I could feel it. I started moaning, she kept going faster and faster until, suddenly the door opened and Nick walked in.
We both lay there in shock, he stood at the doorway, eyes fixed on us, when suddenly he reached down and pulled out his penis! it was REALLY BIG!!!!
He motioned for us to keep going and Jo did just that. We were going for five more minutes, jo doing me and herself and Nick still in the door way working himself when suddenly it hit me in a huge bang, it was extraordinary, and after, I just collapsed, light headed. IT WAS GREAT!
Jo and I have had another experience after that (when she introduced me to Solo Touch) I will post that later, thanks guys!
