Babysitter blowjob

I had my first blowjob from my babysitter at 9.  It felt nice but no cum.  A year or so later I was thinking about my babysitter and touching my cock when what I know now is cum came out.  I told my sitter about what happened and she said she had been waiting for this and pulled my pajama bottoms down.  Not 20 seconds later I had my first real blowjob.  She did not stop playing with my cock, she kissed it licked it and went back to sucking it.  Probably not more than 10 min. later I had the best ejaculation of my life. That was almost 60 years ago and have been trying to get the same feeling.  I have had hundreds of girls blow me and while many came close, none were as good or better.           
ANY IDEAS?
