I saw you outside my room. Were you watching me have sex with my boyfriend you perv? I saw what you were doing.. jerking off?? What if I told step-mom? Your dick was.. pretty big though.. like nice. You're my step-brother so it's not like I think about your dick but.. let's make a deal. You take it out and finish what you started and I won't tell step-mom about this? I show off my lingerie and some positions I was getting fucked it while telling you how to stroke your cock for me. I flash you my tits once but that's all you get before I count you down to cum hard!
