The next twenty minutes, spent at intensity 7, drove Kate crazy. She was desperate for a little relief from the madness between her legs.

Of course, Rick noticed her internal struggle, as well as her external struggle, realizing how close she was getting. Her whole body was flushed, her eyes screwed shut, her head down, chin resting on her chest, hair covering her face so anyone who walked by didn't notice that something was up, her skin was glistening because she was sweating lightly, her fists were clenched, and she was fidgeting in her chair.

Knowing that he wasn't ready for her to come yet, and, if he were to be honest, just wanting to torture her a little, by not giving her any sense of relief, he reached into his pocket and pressed intensity 1 on the remote.

Just as Kate was ready to go over the edge, the vibrations decreased drastically, and prevented her from the orgasm she so badly needed. She looked up at Rick, still flushed, and turned on as ever, and saw a smug grin on his face.

"Not yet," he said.

"I hate you," she gasped, putting her elbows on her desk, and rested her head in her hands.

Rick leaned over, and whispered in her ear, "Oh, Kate, we both know that you most certainly do not hate me."

Just then, the elevator dinged, and Ryan and Esposito walked in.

"Morning, boys," Castle said.

"Morning," they both replied.

Ryan walked over to his desk, and sat down, while Espo stopped at Kate's desk, and looked down at the detective, who still had her head in her hands.

"Is she okay?" he asked Castle.

"I'm fine, Javi, it's just been a long day," Kate responded, even though she knew he wasn't talking to her.

"Long day?" Ryan asked, "It's only 10am!"

One hour down, seven to go. I can do this, Kate thought.

Castle chose that exact moment to increase the intensity again, to three, which, in turn, earned him a death glare from Kate.

Gates came out a few minutes later, and called Ryan and Esposito into her office, to inform them about the few members of Karpowski's team being sick, as she had informed Kate earlier. Karpowski came around the corner with a file in hand, and walked over to Kate's desk.

"Hey, guys. Beckett, could you please do me a favor, and run down to the morgue, to see if Lanie's done with the autopsy files, for my case?" she asked.

"Sure, no problem."

"Alright, thanks," and with that, she walked away.

"C'mon, writer boy, field trip." Kate said, standing up from her chair, her knees buckling slightly before she got control over them again. Rick couldn't help but snicker when he saw how affected by this she truly was.

"Need me to carry you there? You don't want to fall over," he smirked.

"Just remember that I have a gun," she said, walking towards the elevator, Rick following closely behind.

When they were both standing in the elevator, Kate pressed the button to get them to the morgue, and turned to look at Rick. "Of all the stupid things you've done, over the years we've known each other, that have annoyed me, this has to be the most annoying. How did you ever come up with this idea, anyway?"

"Mostly fantasies," he replied, honestly, "The idea of you all hot and bothered, because of me, and you can't do anything about it? Quite a turn on... And when the opportunity presented itself, I had to jump at the chance to inflict sweet, sweet torture on you."

"Sometimes, I worry about what goes on in that head of yours."

"Which head?" he joked.

"Touché..."

"Wait, wait, wait... Are you implying that you've thought about my other head before?" he asked, a little shocked.

She figured if she was going to be tortured by him for the rest of the day, she might as well torture him a bit. She stepped right in front of him, face a few inches away, quirked an eyebrow, and in a quiet, sexy voice, said, "Oh, Castle, if you only knew how much I thought about your other head..." she said, glancing down to his crotch, and then back to his eyes.

Then she walked out of the elevator doors, that had just opened, leaving him there, with his chin on the floor. "Close your mouth, Castle," she called back to him, not even turning around, "You don't want to catch flies."
