My older sister had turned her nose up at her fiancé, a man who'd been blinded in a car crash. On their wedding night, she ran off to fool around with a male model.   My mother forced me to swap my wedding dress for my sister's, ordering me to stand in for her and make it through the night pretending to be her.   Once the lights went out, I told myself that as long as I kept my mouth shut and didn't say a word, this blind man would never know I wasn't his bride.   But this man had unbelievable stamina.   He went at it all night, until my back felt like it was about to break.   It took forever for him to fall asleep. I'd just gathered my clothes off the floor and was about to slip out when a pair of big, burning hands suddenly wrapped around my waist from behind. The man's deep, amused voice purred right in my ear. "Leaving so soon, honey?"
