step-Sister Uses Oblivious step-Brother's Dick

I'm texting my bff and telling her about how unfair it is that I have to share my room and even my bed with my step-brother! He's so relaxed and doesn't even notice when I start doing all of the naughty stuff my friend suggests! I was nervous at first but my friend made me feel better by telling me that if I'm quiet my parents definitely won't walk in and catch us. She doesn't believe how much of a slut I am acting like though and so I send her pics to prove it! We're both amazed he doesn't notice and just lays there in bed, not realizing his step-sister is licking squeezing, kissing, licking, and stroking his throbbing dick. My bff keeps encouraging me to be even more of a slut until I'm doing things I never thought I would, and definitely not for the first time with my own step-brother's hard cock. My bff begs me to let her video call me so she can watch as I do even naughtier things with my oblivious step-brother and I agree!! I give a real BJ to my step-brother and suck it just like I always imagined. Giving him a blowjob is a little scary at first, but I really like it. I rub his dick on my big soft boobs before I start rubbing it on my dripping wet pussy. I'm so gooey from playing with my step-brother's stiff cock that when he start's unexpectedly thrusting he goes inside me without even realizing it. It feels so good I keep pumping back against it. My fat, juicy pussy loves his cock so much. I get on top of him and bounce on it until I cum, with my bff watching the whole time on the phone. I'm not the only one who had a huge orgasm though, and now my step-brother's big load of cum is spilling out of my just fucked pussy and all over his cock and balls!
