Jealous step-sister teases you

I have a bone to pick with you, my adorable step-brother! It appears that your attention has been elsewhere. How is that possible? How could you do that to me? You've been spending so much time with Step-Mommy. What's Step-Mommy got that I haven't? Does she have a tight, toned body like your step-sister? I'll bet that when you're fucking her, you're still thinking about all of this, aren't you? These gorgeous feet... this ripe, plump ass... You're hard now, aren't you? Step-Mommy doesn't make your dick hard like I do. You want my young pussy, not her old pussy. The only reason you hump her is because you can't have me, but you fantasize that you're fucking your step-sister, don't you?
