I could always hear my step-brother jerking off and it was always turning me on. But this time I was extra horny, so I stormed in the room and caught him in the act. He was embarrassed, but all I wanted was to finally see his cock. Turns out his cock is beautiful and I couldn't resist not touching it. And touching isn't the only thing I did. I have shown him some step-sisterly love by putting his dick in my mouth, giving him a proper blowjob. Such a fine dick shouldn't be just jerked off, so I took it between my tits before I turned around and sat on it, bouncing my ass up and down his shaft. I rode my step-brother's cock like a slut and at the end he came all over my face.
