I have been reading on here for a couple days now, and have decided to share a story that I experienced a few years ago.
Every day, I would get the bus to school. I would wait outside the store the stop was at, and see familiar faces every day. There was one girl, and she was called Cara. She was about 5,5 with long blonde hair, very slim with a gorgeous face. She had about C cup tits and a fat ass. Just big in every way shape and form.
We got to know each other quite well waiting for the bus, even though she was in the year below me and I never really saw her at school. We'd laugh and joke and she'd sometimes hug me if she was sad and huddle up if it was raining or snowing, but nothing serious. I'd never really noticed how attracted I was until one day when it was really hot, and we were waiting for the bus.
She took off her jumper infront of me, bent over to put it in her bag, then stood back up and pulled her trousers up, outlining her ass in a great way. Immediately I realised, and was turned on straight away. And so, over the coming days, I started to flirt a little.
