You knew your wife was disappointed with your bedroom performance, and she had told you several times that the sex with her ex was outstanding and she wished you could be as good as him, but her simple pronouncement still came as quite a shock -- and it was obvious that everything was about to change. You knew that she was about to make you her cuckold, and you feared (with good reason) that she might never have sex with you again.
