I let him touch me
I was 10 at the time and he was 13. He said he'd give me $5 if I let him see me and touch me.
I took off my shorts, he knelt in front of me and ran his finger up and down my slit. Thankfully he never tried to put anything inside me, he just kept rubbing up and down.
We never talked about it. I just pulled up my pants and collected my $5.
