First time I got busted I did it to myself because I didn't know what the big deal was. I was 9. It was in the shower and I fell to my knees instantly.
First time someone else busted me I was 15. I made a bet I knew I would lose where loser got kicked in the nuts full force. I was in gym shorts so he saw me get aroused and thought it was funny.
First time I busted someone else was during a game of hide and seek. We were hiding lying down side by side and I sucker punched him in the balls. He rolls around holding them for so long. I was 14 he was 11.
It was recently on omegle. The other boy made me tie shoes around my sack and drop them over and over and squeeze my balls too. I was sore for days.
