my firstcock SeXStoRY

I was 13 and very aware of my sexuality, my b*****r was 17 and I knew that he liked to look at me when I was getting undressed. I used to leave my door open just a little when I came home from school and was getting changed. I would slowly take of my tie then unbutton my shirt revealing my very large tits. Even at 13 I was a D cup...running my hands over my tits I pull the shirt of...I unzip my skirt and let it drop to the floor, bending over to step out of it...I glance in my mirror and see my b*****r standing at the door his large cock hanging out of his pants. I take of my bra to change into 1 a bit sexier...my tits spring free and my nipples stand out. I see my b*****r step away from the door and I knew he was going to wank himself off...how I wished he was wanking into my mouth. A couple of weeks later our parents had gone away for the weekend leaving my b*****r in charge, I decided to have a bath and told my b*****r. I ran the bath and got into it, it was so lovely I was fingering myself and pulling on my nipples, suddenly the door opened (I had forgot to lock it deliberately) and my b*****r stepped in. He said nothing just got his cock out and started to piss into the toilet, when he was finished he shook his cock and turned towards me, without saying a word I took his cock in my mouth, mmmmmmmm I ‘ve wanted that for a long time I said. He started to fuck my mouth pushing his cock in deeper and deeper, how many times have you done this he asked, I pulled back and said this is my first you are my first cock, he was surprised because I was doing it so good. Do you want to taste my cum he said, oh yes please, he pushed his cock back into my mouth and fucked it really hard. I felt his cum in my mouth it was hot and salty and tasted so good. I held it in my mouth then looked up at him and swallowed. That was good little s*s he said, how would you feel about doing that for a couple of my friends?
