You know that fantasy, that itch at the back of your mind, the one you occasionally scratch for a few seconds, then leave well alone? You know it, come on, we all have it. Well, this was mine. I knew my wife Lucy had a bit of a past, okay, fine, I'll admit it. She was a bit of a slut in college. Like she said, she loves sex and loves to cum. So I guess my mind just wondered, and wandered from time to time. I couldn't help but imagine the old Lucy, what it would be like to watch, to see her rediscover that old side of her. And now here we are, happily married, faithful, almost boring, and she's about to turn thirty. So I've booked us an amazing vacation. Now I was expecting the dirty talk, i'm used to it. No, in fact, I love it. Going down on my wife as she tells me how she sucked some guy's cock in the back of a restaurant at college is so hot. But what I wasn't expecting was us laid on that hotel bed, my face between her legs as she looked down at me and smiled as she said, 'I want to make this a Dirty Thirty.' Suddenly, fantasy came crashing down to reality around me. It was like a switch was thrown, and the old Lucy was suddenly in the room, legs spread, right in front of me. And before I knew it, I AGREED!
