You just caught her, red-handed. You had your suspicions, and those suspicions were fueled by your wife. And sure enough, your wife was right. The babysitter (who uses the cash she earns sitting to put herself through freshman year at the local community college) goes through your wife's lingerie drawer while you two go out. This particular night you left the party (without your better half) to catch her. And sure enough, you did. Wifey was right! And as your babysitter -- Casey Calvert -- is sitting there, in your wife's undies, she makes a startling offer. An offer you decide to take up. After all, Casey promises to keep The Secret.
