So glad I caught you because we have a very important matter to discuss like right now. I have something to show you. I want you to look very closely at these panties and ponder as to why they are completely stiff. They aren't even stiff in the right place like where my crotch rests. They are a crumpled ball of stiffness! Any idea how they came to be this way? After I sniffed them I knew exactly why they are sticky so don't lie to me because it's either you or your step-dad that made them this way. You still deny having anything to do with this? Looks like there is only one way to solve this situation and prove you are the reason my panties are corroded with cum. I demand you lie down and I will milk you of your cum. You will see that what I take from your cock smells exactly like what you left in my panties. This will prove in fact you are a perverted panty stealer stepbrother.
