Sixteen year old Dawn was a well known hard nut she was prepared to have a go at anybody and not much or anybody scared her, so one day when on her way home from school when her sister Amy who was a few years younger than what she went to her and pointed out a boy telling her that the boy had just flashed his dick at her Dawn went after the boy, the boy ran into a derelict building with Dawn chasing after him, once inside the building Dawn saw the boy ahead of her, Dawn started walking towards the boy who just stood looking at her and smiling, Dawn shouted at the boy ” you dirty cunt you, you flashed your cock at my sister your going to regret it and walked towards him, after a couple of paces Dawn heard a loud creaking sound and felt herself falling, Dawn had fell through the rotten floor, Dawn landed on something soft but was still winded and very dazed, Dawn felt the floor that had landed on her being lifted off her and saw the boy she had chased lifting stuff, things were still hazy and Dawn could not focus properly, Dawn felt her panties being pulled down and off then her love tube being rubbed, Dawn started to focus a bit better on things and saw the boy she had chased was in front of her with an eight inch erection, Dawn tried to move but was still weak and could not move, she felt fingers slide up her love tube and start to probe around then after a few minutes the fingers were pulled out and Dawn felt the boys dick slide into her now moist love tube and start to thrust in and out and after a few minutes Dawn climaxed, the boy carried on thrusting away into Dawn making her cum a second time but still carried on thrusting away and after a few more minutes Dawn climaxed a third time before the boy pulled his dick out and squirted his cum over the floor, the boy stood up, Dawn saw it was a boy who looked a bit younger than herself. After about ten minutes Dawn was clear headed again she stood found her panties and after putting the on went into the street where she saw Mike her fourteen year old brother with Amy. Dawn told Amy she had lost the boy inside the building, Amy told her that Mike knew the boy that his name was Mark and in Mikes class at school, Dawn told Amy she would get him tomorrow. The next day Dawn was waiting inside the derelict building with her panties tucked away inside her bag.
