Watching

I watched my wife reach into his trousers, pull out his hard, thick cock. "Go on," he said.

I waited for her to frown, as she would with me, tell him no, as she would with me, make it clear that giving blowjobs was something she did not do. Ever. 

But she didn't. Instead she licked her lips, knelt in front of him, leaned forward, and slowly and seductively licked the head of his cock.

He looked at me, grinned. "I know what you're thinking, boy, you're thinking what the fuck, my wife said she doesn't give blowjobs. You're half right, you're missing the qualifier, she doesn't give you blowjobs."

I saw my wife glance at me, a subtle apology before she opened her mouth and took the head of his cock between her lips.

In that moment, I came to understand that all my fantasies about my wife sucking cock didn't involve her doing it to me, they involved her doing it to a man.
