The bet started this way: they were talking about how they had been married just over 10 years, and in that decade, had only had sex with each other. Each wondered, somewhat secretly to them self, if they even remembered how to make love to someone new, and if they did, what it would feel like. She said she knew him so well, she knew the shape of his cock by memory. The texture, even the taste.
"I bet you don't," he said.
She looked at him puzzled and challenged. She didn't like being doubted.
"Come on," he said. "You think you know me just by my taste? Seriously?"
She nodded, her eyes narrowed. She would defend herself if needed.
"Yeah right," he said, laughing.
This only made her mad.
"You're just saying that, but you couldn't prove it." After 10 years of marriage, he knew how to push her buttons in an argument. She was so stubborn, and always had to be right. Even if she wasn't.
"Yes I can," she said. Then she added the hook, what she knew would push his button: "I bet you."
And so it started. A bet between husband and wife that she could not tell his cock from a stranger's just by taste.
The process was simple. All that was required was a blindfold and another willing (and impartial) participant.
