I was 7 and I was over at my baby sitter's house with other children.  I remember it like it were yesterday...
 
Her daughter and I had become friends...and curious.  She was about my age.  I knew nothing about sex...and...apparently she did.
 
We went into the bathroom while her mother was doing laundry.  Her daughter, Laura, closed the door behind us.  I remember feeling warm and tingly inside.  She blurted out, "I'll show you mine if you'll show me yours!"  I remember thinking...."well, ok, but she has nothing to show me.  I am the one with something to be embarrassed about!  She's got nothing!"
 
I took my little boner out and remember it flinging off of my waist band as I pulled my pants down to my knees.  It was stiff as a nail and swinging and bouncing about.  She said "Cooolll!"  I didn't know what she meant, but I started to be a little less embarrassed.
 
She took down her pants and I clearly remember where her penis should have been....but it was just a tiny fold of skin....little sideways lips!
 
She asked if she could touch my penis.  I let her...I was sooo surprised about how good it felt!  My hips just went forward and it touched her face!  She laughed!  She told me to lay down on the floor and touch hers if I wanted to.  There wasn't anything there, but I said "ok".  I touched the little fold of skin and she pushed herself into my hand.  She took my hand and pressed it up against her lips and began rubbing my hand back and forth over her lips.  She kept pressure on my hand and with her body pushing against my hand.  Soon we had scooted very close and my lil dick was against her!
 
It felt awesome!  I stopped because my hand was getting tired..but she told me to keep going.  Suddenly I felt something wet on my hand....I thought she peed on me!  I started up and she told me to stay...and told me what caused it.  I was intrigued...and I stayed.  She began to rub herself and show me how to do it.  She moved closer and took my fingers and began rubbing herself with them and pushed one of my fingers inside of her!
 
It was so warm!  I wondered how far I could go!  She let out a little scream and told me to stop.  She told me I had hurt her because of my fingernails.  She then told me that is where the boy's penis goes in a girl.  I thought this was strange!
 
She rolled onto her back and told me to get on!  I swiveled onto her and she grabbed my lil dick and began to rub it.  It felt so awesome!  She rubbed it around on her lil lips and it went in!  She pushed herself upwards and onto it!  I couldn't do anything but push against the pressure as it felt so goooddd!
 
She began to move and told me to move , too...but different then her!
 
It was sooo warm and moist!  I couldn't help but to thrust into her as hard as possible!  I felt a strange feeling inside me...it drew me to her...to move faster and faster and to push down on her as much as I could!  She was was making lil screaming noises and then it happened...
 
Her mom walked in with the laundry!  She saw us and yanked my up and out of her with a popping sound!  My lil pecker was bouncing around as I tried to cover it.  She was screaming at the top of her lungs and threw me up against the wall and jerked up Laura, too...who was lying in shock.  I pulled up my pants and ran outside and hid till my father came.  She had called him to come get me and never come back!  Laura had found me hiding under the deck and wanted to continue doing what we were doing!  I thought she was crazy and ran to my father's car when he drove up.
 
I never saw Laura again.  My dad never said anything to me nor did I!
 
...I soon learned to masturbate and have masturbated to that story time and time again...even now.
 
Where are you "Laura"?  This was in California around El Cajon or San Diego.
