This happened when I was about 11 years old, on a family holiday.
One day I was playing soccer with some of the other kids on the campsite when I got hit in my nuts by the ball.
So hard, one of them went up into my belly and got very, very painfully stuck.
When I laid on the grass for a while, hurting like crazy, one of the boys went to one of the girls that kind of worked on the camp site, overseeing and "babysitting" the groups of playing kids, to get help. I think she would have been about 19 or 20 years old.
When I told her what was wrong she didn't really know what to do, so she picked me up and carried me to our mobile home and laid me on my bed.
Because of the pain and the fact I could only feel one testicle in my sack I was crying and a pretty panict, so before she would go and call a docter maybe, she wanted to see 'the problem area', to make sure nothing was critically wrong.
So I tried to relax and laid myself on the bed and she carefully took off my shorts (except for my socks I was completely nude).
She laid one hand on my hurting underbelly just above my little friend and with her other hand she carefully examined me.
At that point the pain got a bit less and I relaxed a bit more and she kept gently rubbing my belly to make me relax and try to take some pain away. And surely after a few minutes I felt my nut slowly sinking back in it's proper place.
When I told her I thought it was back in place she felt it again with her other hand and said she indeed felt 2 little balls again
I felt the pain slowly disappering and enjoyed this moment so much I hadn't noticed my little friend became bigger.
When I realized and looked at her, she was looking at my little boner all the time and still touching my balls.
Suddenly she looked me straight in my eyes and kept looking at me when she started caressing my little boner.

I was so flabbergasted and confused I couldn't say a thing. No girl or woman had ever touched me there in that way.
In that period I started playing with myself sometimes so I kind of knew what was goin on but this was so different and I liked it a lot.

Offcourse it didn't take long before, what I consider, my first orgasm, shiverd through my body.
We both laughed a bit awkward and she immediately told me this should be our secret and I really couldn't tell anybody about it or she would lose her job and maybe worse. So we swore we'd never tell.

So this was my first sexual encounter.
Soon I will write about what happend the next day.
