The rules for your “guess who” game are simple: strip your wife, blindfold her, and double penetrate her everywhere until both men cum. She guesses who spurted where. If she guesses wrong, you choose the next guy to fuck her. If she guesses right, she picks. She’s getting so good at guessing that you’ve been meeting all her co-workers lately and spending a lot of time with her boss. It’s just a bonus that the game has improved her job satisfaction, too.
