You're in a rush to get out the door and forgot to clean up the evidence of your latest panty raid into stepmoms' dirty underwear pile. Stepmom decides to clean up the pile of clothing you left behind and finds her panties covered in your cum. She takes a whiff and feels your creamy load and realizes she's not upset; she's incredibly turned on. Soon she's masturbating with her used panties and imagining what it would be like if her stepson was filling her up with that load. Stepmom hatches a scheme and decides to hide some of her dirty underwear in your folded laundry to see if she can catch you in the act.
