Brother to Whore

I was at my younger brother's birthday party and he was turning 18. I was his older brother who was 26 and my life had gone horrible and I had wasted my time and failed at life and yet my younger brother seemed to have everything going for him. He was about to blow out his candles and I jokingly said "Make a wish" What I didn't expect to happen was for his wish to come true. He had wished for his perfect girlfriend, a sexy cougar with big tits and a fat ass. Then as soon as he blew out his candles, I turned into his dream girl wearning only a green dress with my tits out. I was confused at first as I had managed to keep my brain to an extent, but I was also apparently completely obdient to him and his wishes. So when he ordered me to get on me knees and suck his cock I did, even though I tried to resist. Every time his dick slid in and out of me, I lost more and more of my mind to become his slutty girlfiend. By the time I finished sucking him off, I had already lost half of my brain and started to enjoy it. He pushed me over onto his bed and then tore of my sexy dress and started nailing me from behind and that completely melted away my mind. and so now there i was sitting on his sofa having him plow my pussy and I only begged for more and let me tell you, I couldn't be happier to be his whore.
