It was summer, I was just barely 13.  I was on my knees, holding the 12 year old boy next door by his butt cheeks with his cock in my mouth.  I didn't realize it but as I was feeling around it with my tongue exploring it, I was driving him to an orgasm.  He grabbed my head, shoved his hips forward and started shaking.  I really think if I hadn't had a good hold on his cheeks, he would have gone to the floor.  You see, we had been talking about the rumor going around that the 13 year old girl across the street would give blowjobs to older boys.  So we were talking about what a blowjob would feel like and, since we were at my house alone, it got to a "I will suck yours if you suck mine."  I went first because I really wanted to try sucking a cock to see if I liked it.  Now I had blown him and it was his turn.  He was a little reluctant but he did go ahead.  I wasn't thinking about warning him when I started to cum and when I started cumming in his mouth, his eyes got real wide.  He jumped up and barely made it across the hall before he threw up in the toilet.  Of course we were both embarassed so he went home.  We didn't get together for three or four days but finally he came over after my parents left for work.  We kind of talked around the elephant in the room until he finally said he didn't like giving a blowjob but it felt good when I blew him.  I thought for a few seconds and told him I liked doing it.  We both were quiet for a minute of so when he asked "want to do it again?"  That's when I basically became his blowjob bitch for the next three years until we moved when I was 16.  Nobody thought it was unusual for us to be together so much since the rest of the kids on our street were girls and the only boys were two bullies on the street behind us.  We avoided them like the plague.  Any idea how many times a 13-14-15 year old can cum in one day.  I think the most I sucked his cock in one day was five times.    I tried to figure out once how many blowjobs I gave him in just over three years.  We would average anywhere between 10 and 15 per week in the summer but probably only 3 or 4 a week during school.  So let's say it averaged out to 5 a week. That's 52 weeks a year plus 2 months additional or 8 weeks for a total of 164 weeks.  Averaging 5 times a weks for 164 weeks would be 820 blowjobs.  If it was 4 times a week 656 and even just 3 times a week would be 492.  Let's just take the lower, round it off and say 500 blowjobs.  How many 16 year olds could say they had given 500 blow jobs before they were a junior in high school.  We had some girls in our class who were promiscuous but I am sure I was the biggest slut in my entire class. 

Oh, and the girl across the street?  Yes she was blowing older boys and her mom caught her.  I always wanted to talk to her and compare notes on the best way to get boys to cum but I never did.
