My step-son is such a pig! Always leaving his dirty laundry strewn about his room...and just look at this bed when I specifically asked him to start making it...Just leave it for me, god...woah, what are these panties? They look...familiar. Woah, these are mine! What is my step-son doing with my dirty panties...look at this white stain. My god, is that me or...him? I'll just sniff it a bit...yup that is him! My own step-son, jerking off into my dirty panties! I have to admit...it's kind of a turn on. Maybe I'll just sit here for a minute. Smell. God, what is wrong with me?? You left your textbook for biology in your room, so you run back to pick it up. When you open the door to your bedroom, you see a surprising sight. Your step-mother is on your bed, pants down, rubbing her soaking wet pussy through the dirty panties you stole from her bedroom! You can't believe it. Your cock stirs in your pants, imagining your step-mother pressing your cum against her pussy. You've been using the crotch of her panties as a cum rag for a few days, and you cum so much when you stroke with them...you clear your throat and watch her jump. She tries to make excuses but its no use. She's caught. And you're going to use this compromising position she's in to your advantage. You've fantasized about this. Sliding your cock against your step-mother's pussy. Pushing into her, pumping away until she begs for your cum
