Caught Wearing Panties

I have worn panties for years. My wife knows and will buy panties for me, but is not very enthusiastic about it. One day last summer, I was wearing panties under loose shorts and my grown niece saw them. She told her mom; my wife's hot sister. My sister-in-law found a reason to make a bet, where the loser would wear panties bought by the winner. I lost. She bought me a pair of white, lacy panties which she insisted I model for her and pleasure myself in. I am hoping for a repeat.
