Non fortress play. I was restrained and mistress was dressed, I had to guess the color of bra, panties and style of panties. Had to guess all 3 at once, when I got any wrong she placed a clothes pin on for every wrong answer, same basis of the game of clue. I kept guessing, i want to say my balls only fit 25 clothpins. Of course the only way it stop is guess all 3 right at the same time or beg to end. I had already knew the consequence of giving up.
