My step-brother interrupts me as I am doing some stretches in my room. My step-brother has a little problem and needs his step-sister to help him. He needs help because he is a virgin. So I take off my pants to get him hard and suck his cock to get it ready for my pussy. I am so lucky to be my step-brother's first. He can't handle seeing my tits because he could cum early from that (so I keep my top on). I ride his cock with my hands behind my head because I know he likes that kind of porn. Finally, I beg for him to cum inside me and tell him we need to practice more next time.
