Girfriend's first orgasm

As I've talked about my first girlfriend here before, we were both young teenagers, innocent, when we started dating and having sex and slowly discovering each other's sexuality. From that time there are many nice memories that I like to share. This time for her first orgasm. We were at her house alone, as usual we kissed and caressed each other, at the end we were naked, we had not yet had classic sex, because she was afraid of getting pregnant etc., but she gave me wonderful handjobs, I in turn caressed her pussy, but never again I had not brought her to a real orgasm. That time she sat on my lap in a horse rider position and passionately rubbed my dick, while I rubbed her vulva and finally felt the right spot. :) After a while she started shaking and twitching, panting loudly until she splashed my handful with her vaginal juices and finished with a scream. It was a fantastic feeling for me too.
