Caught Sniffing step-Sister-In-Laws Panties

It seems you've finally been caught!! Yes you know what I'm talking about you little panty perv! You and your wife have been invited to her step-sisters house (I'm a friend of hers) along with others, it's a warm day and everyone is relaxing in the garden. She asked me to quickly nip to her bedroom and grab her laundry and what do I find?! You!! What are you doing in there?! I stand there with her panties in my hand questioning and quizzing you, seems you've finally been found out by yours truly! I'm the last step-son you could ever want to discover this, I mean with your wife you can work around her and lie to her whereas I'm your step-sister in laws bratty friend who has never really liked you anyway, I think I might bank that one for another day just in case I ever feel like blackmailing you! haha
