Hello dear step-brother-in-law. I have a confession to make. I walked by the bathroom while you were showering and I couldn't help peeking inside, seeing your huge cock. I know I'm supposed to be helping you and my step-sister out cleaning, but I just dont think its fair that she gets the man with a big cock. I think she should have to share. Let's masturbate together before my step-sister gets home. I'll talk dirty to you and tell you to stroke that big cock to me. But we have to hurry! We don't want my step-sister to find out!
