Jake Stone was a man of the world. In his youth, he had sown his wild oats as much as any other handsome varsity quarterback in the middle of nowhere Oklahoma. So waking up with a naked woman in his bed wasn't an entirely new experience for him.

What was unique about this particular morning was that the woman in question happened to be Cassandra Cillian, his fellow librarian and the last woman on earth he should ever have slept with. He knew the minute Jones had suggested this impromptu trip to Vegas that it was a mistake.

He tried not to look at her, as he pieced together the night before. After recovering the Golden Fleece, Flynn had decided that they needed a break. Of course Jones had quickly suggested that they use the back door to go to Las Vegas and Cassie had surprisingly agreed.

Jake considered not going, but he was concerned about the looks Jones was giving Cassie, so he tagged along just to keep an eye on things. Flynn booked them rooms at Bellagio, so they headed there first to check in. While he was in his room, Jones had apparently convinced Cassie to hit the casino floor with him, and they were up two thousand dollars by the time he found them at the high rollers poker table.

"Can I talk to you for a minute?" Jake said, tugging Cassie from the table when there was a break in the game. "Are you out of your mind counting cards in Vegas, Cass? Do you have any idea what they will do to you if you're caught," he whispered into her ear.

"If this is anything like Atlantic City, I don't think it will be a problem," she replied, quirking a smile. Jake sputtered for a moment in shock. "Don't worry, Stone, I know what I'm doing, and I am not even helping Zeke. He is just that lucky."

As the night went on, he started to relax and enjoy himself. When Cassie switched to craps, he even played with her for a bit. They were all winning and the feeling was intoxicating, or maybe it was all the free drinks. Every time Cassie won, she would jump into his arms and giggle like she had the first time she met Santa.

"I win!" she grinned excitedly after rolling snake eyes at the perfect time. "Can you believe it, Jake?"

"You know how amazing you are, Cass," he shrugged, though a small smirk showed through his tough guy mask.

At two in the morning, the action at the tables began to die down, and Cassie, who was full of energy after her big win, begged them to go dancing.

Jake was pulled from his memories by a rustling of covers. Before he could react, Cassie had rolled on her stomach, her arm draped over him, as she cuddled into his chest. He didn't breathe. If there had been any hope of this being an innocent mistake, it was erased by the sensation of her naked chest pressed to his.

"I win!" she mumbled in her sleep, clearly still dreaming of the night before. Looking around the room, he realized that it was hers. If he left now, she might never know about this little mistake and they could continue to work together without the cloud of awkwardness that generally followed a one night stand.

Carefully, he slid out from under her, taking time to tuck the duvet around her. It didn't take long to round up his clothes and a few minutes later he was back in his own room, trying to shower off the smell of honeysuckle that still clung to him.

Cassie woke with a smile. She felt more relaxed than she had in ages. Though her legs were a little sore, she chalked it up to the combination of dancing all night and the wicked hangover she knew was going to hit full force the moment she stood up. She was however a little surprised to find that she was completely naked. Then again, the clothes she had chosen to wear the night before had been very constricting, so maybe when she came in at god knew what time last night, finding PJs had just been too much work. Yes, that had to be the reason. It couldn't possibly have to do with the explicitly vivid dream she had had about Jake.

Knowing that she would feel better once she ate something, Cassie quickly got dressed, brushed her teeth, and headed downstairs, sending a text to both Zeke and Jake to join her if they wanted. She was already playing Keno and eating the biggest plate of waffles he had ever seen when Zeke slid into her booth.

"Hey there, sugar mama," he teased. "You leave any for the rest of us?"

"I was a bit hung over this morning," she admitted with a laugh.

"A little? I had 999 tap dancing gnomes in my head this morning," he joked before giving the waitress his own order. "Have you seen Jake yet? He was worse off than both of us put together."

"I texted him, but I haven't heard anything," she shrugged. She wasn't surprised that Jake had ignored her text. He had a habit of going off on his own. In fact, the real shock was him coming ago in the first place. They continued to chatter about the last case until both were done eating.

"Shall we hit the tables until it's time to go?" Zeke asked, offering her his arm like a gentleman.

"We shall," she agreed. Neither noticed Stone watching from across the room.
