A long time ago, when I was 15, a girl in my year called Zoe got picked on by a girl from the year above called Christine - I think it was over a boy
Anyway, Zoe really thought she was something special - she was pretty but nothing spectacular - whereas Christine was a tough, blonde haired bitch, who I found incredibly attractive, with lovely legs and a great body
Whilst a group of around 30 of us gathered, it kicked off, and Christine gave Zoe a battering, split her lip, made her nose bleed, and blacked her eye, and by the time she was dragged away, she'd put Zoe on the floor in the corridor, where I think she'd have given her a kicking if it had carried on
From then on, I was hooked, often imagining fights between girls at school, including my girlfriend at the time, who was a petite blonde, and I'd enjoy imagining her getting worked over even when I was fucking her
That led me on eventually to imagining celebrities fighting, then writing stories etc
When I was a teenager, I thought I was the only person who thought like this, but realise that there are many of us, and as long as the fights remain in our imagination, it's fine. Unless the girls were professional boxers or wrestlers, I couldn't watch an actual fight these days, I promise
