I played the role of the step sister before, the innocent one who gets tricked into a creampie. But this time I wanted to try another taboo family roleplay in which I was the horny slutty sister. And in this story I catch my brother jerking off to porn on his laptop. Since his cock was thick and hard and my pussy was already wet, I went on and took advantage of my new brother's boner and rode his dick like he's never been ridden before. I basically used him as a human dildo to make myself cum, and when I had enough, I went down on him to check how my new brother's cum tastes. His sperm is pretty delicious, making me thing that I'll taste a lot of it since I have a brother-dildo at my daily disposal, living in my house.
