First blow job story

What was giving your first blow job like and where did you do it? I was 17 and we were at this empty Park in winter. It was after dark and this park was private with trees surrounding the place. I was nervous that I wouldnt do as well but he seemed to like it. I didn't swallow because I was afraid it would be too much for me. I also remember that it started to snow part way through. Haha it was fun but I do prefer to do dirty things behind a closed door. I did blow him in a church parking lot once though.(sorry Jesus)
