Sweetie, step-Mommy needs your help. I forgot to do laundry, so the cleanest panties I have are these cotton fullbacks I wore to the gym earlier. Be a good boy and smell step-Mommy's panties so you can tell me if they are clean enough to wear out tonight. What?! You think they smell GOOD? But that doesn't make any sense! There must be something wrong with your nose. Let me test it. Here's a dirtier pair of panties that's even older. You think those smell good, too?! What about this pair with weeks-old pussy stains? Or this nasty wet pair that's full of step-Mommy's ovulation juices? Wait, are you getting an ERECTION from smelling step-Mommy's nasty, wet, juicy panties?! Oh, I see how it is. You're a little pervert who gets hard for stinky panties! I bet you want to see the holes that make step-Mommy's panties so smelly while you jerk off. How about these nice step-Mommy milkers? No, it seems like the thing that gets you the horniest is just sniffing step-Mommy's dirty panties while I talk about all the ways they get so stinky and nasty until you milk out your cummies. From now on your job is to sniff-test all of step-Mommy's dirty panties - if your penis gets hard, I know that they're too dirty to wear!
