First ball busting experience

It happened in lunch break at school and I was with my mates heading back towards main building from football pitches and a group of girls were in front of us who we knew . I started teasing a red head called Diane and we were laughing and I didn’t really notice her turn sharply round and swing her foot right up into my balls . The pain was the most excruciating pain I’d ever felt and it went all the way up my stomach . I remember I fell straight down to the floor writhing in agony cupping my balls and wrenching to be sick . At the same time I got the hardest boner I’d had so far . The worst part was I had to be taken to the school nurse as the pain was so bad then to a hospital as the school wasn’t sure my testicles had ruptured . Still I had this mega boner that would not go .
