Three weeks ago I caught my twenty three year old brother fucking his on off girlfriend in our conservatory. He knew my parents were away and must have thought I was still at college. I stood and watched him fuck her for over quarter of an hour with out him even knowing I was there. And by the time he'd cum up his girlfriend, I orgasmed from playing with my clitty after lifting up my skirt and moving my knickers to one side. That's because I got to see just how big my brother is. And that's fucking enormous. His cock is easily way larger than any boyfriend I'd ever had and he fucked that girl so hard and for so long, I imagined as he fucked her, it was my pussy and arsehole his cock was pounding.
Watching her lick and suck his dick after he'd pulled out of her arsehole, was the final straw for me. And I knew right there and then I wanted my brother to fuck me. Each da that goes by now I try to find a way to entice him into my bedroom to have sex with me, but I either chicken out, or my parents are at home. It's getting to the point I might just jump on his the next time my mother and father are out. That or walk around naked, as I'm so desperate for his cock and his beautifully fit body. God I'm so horny for my brother right now.
