Jessica was my mother's friend's daughter.She was eleven years old at that time and I was just turning seventeen.One evening as I returned home from school,I saw Karen's mom's friend, car in the garage.As I entered the house I saw that my mom and Karen were all dressed up.They were going to meet my dad and Barry,Karen's husband,for some gala affair.I asked if Jessica and I were going but they said that such an affair would bore a couple of kids like us.I immediately took offence by the remark,but Jessica was even more offended,maybe because she didn't get a chance to wear her pretty dresses and mild make up.Intead I was supposed to baby sit Jessica while they were away,because they didn't know what time they would be back. As the car pulled out of the drive way,I went back inside to the kitchen to make myself a sandwich.Jessica was in the refridgerator taking out all the stuff.Even though she was just eleven,Jessica and I were good friends ever since she was a baby,each knowing what the other were about to do or think,so I wasn't the least bit surprised to see her preparing to make us sandwiches.A slice of bread fell to the floor.Groaning her annoyed groan she bent to pick it up,and even thoug I knew she was a kid,My dick was asking where did she get that ass from!Her butt was medium sized and plump and round,it had a very nice shape.As she straightened my attention went to her frame,her body was well proportioned. She then turned to me and asked if Rex,my dog,will eat the bread.As I went to take the bread from her,I looked at her chest.There was definitely some breasts coming out of there,and from the looks of it they would be all out soon too.As she smiled and walked back to the counter,her long shapely legs moved her ass in an alluring dance. Dinner went by with us teasing each other and talking bad things about our parents for not letting us go with them.It was getting late so Jessica and I sat on the couch looking at television.We were looking at some childish show that she liked but I wanted to look at something else,so I switched the channel.She got angry and fought for the remote ,which she knocked out of my hand and then fell away near the TV.We both went after it ,resulting in a wrestling match.I tried to grab it but she put all her weight on my back and then I turned over,then she sat on my belly.As I pushed her her ass then slid on my groin above my dick.I tried to move again but she just sat there with a grin.She was strong for eleven,but I then raised my hips and this ccaused her to lose balance and she fell onto my chest.As her head hit my chest we were still grinning but as she pulled herself up so that she can face me, she shrieked her arms were weakened but I caught her just in time to prevent our heads from crashing,but not in enough time for her lips to touch mine.The weight of her head was just enough to make her lips melt into mine.We remained like this for two seconds until she remembered to pull herself up.We looked at each other and then I mumbled an apology and went into my room.I lay on my bed feeling sort of scared and then I dozed off. I woke up with Jessica lying in bed with me.I didn't even know what time it was,but I was under the covers with her.She told me that our parents were on a party boat belonging to our fathers' boss and they wouldn't be home until tomorrow.She added that she locked up the house for me.What a good babysitter she was,I thought.Suddenly she wrapped her arms around me and began to kiss my neck.I was still drowsy so I was not resisting.Suddenly it occurred to me that she was so warm,because my hands found their way to her petite body.She was naked!She was now on top of me and was trying to make her way back to my lips.I stopped her and told her that it was wrong,but she told me that she loved me and wanted to do this so long now,and if I had done this so long ago she wouldn't have had sex with a boy that was her age in her school.Shocked,I listened to her tell me about Aaron,her
