"Okay, Reid. This is it. This has to stop!"

"What? I thought you liked it." I wished I could walk away right about then, but what chance did I have against him? Reid's big brown eyes were staring at me, almost glistening, giving me the illusion that he was crying when really he was just a big faker. His bottom lip was poking out to, just a little, just enough to… curse him.

"Stop it," I said, the words coming out in an unmanly squeak as I tried to look away. Reid didn't let up – a soft whimper tore through my ears. Reid knew I couldn't take that sound.

"Stop what?" He sounded so innocent. That dirty little cheat!

"Stop batting your eyes and pouting your lips and making that little whimper like you're gonna cry, when we both know that all you're really trying to do is distract me from my main argument."

"Which is?" Reid gave up the sad pouting and glowered at me.

"We can't have sex on cases anymore!" I cried, throwing my arms up behind me.

"Why not?" Reid asked. His voice was coming dangerously close to a whine.

"I need to list the reasons? Okay, fine. One, during cases we are up all day and most of every night. And when I'm on five hour sleep shifts every twenty-four hours I want to sleep. Which is something I don't get to do if you're mauling me."

Reid's mouth fell open as a light blush dusted his cheeks, "I do not maul you."

"Well, you're certainly energetic," I coughed. At the sight of Reid's glare, I decided to change the subject. "Besides, that's not my only problem. The others are starting to suspect something. I mean, just last week JJ was asking me whether I thought the cheerleaders next door were watching a horror movie."

"Maybe they were," Reid shrugged.

"She was in the room next to ours, Pretty boy. I know whose screams those were, and they were not a cheerleader's. Wasn't because of any horror movie either."

"Well," Reid giggled, "Someone was being attacked." And okay, it was a little cute, and he needed to work on his entendres anyway, but I wasn't in the mood for jokes.

"This is serious, Reid. Are you forgetting we could lose our jobs over this?"

"That's never stopped you before," Reid studied me for a moment, before a small, suspicious smile twisted around the corner of his mouth. "Is this about the time you couldn't-"

"-You swore we'd never speak of that again," I said, staring at Reid in horror.

"I swore I wouldn't tease you about it, which is perfectly true. Erectile dysfunction is a common problem, it happens to all men sooner or later-"

"It was not erectile dysfunction!" I hissed, "I was tired, I had a headache, and I did not want to have sex at work. Which just proves my point; we shouldn't have sex on cases."

Reid crossed his arms over his chest, "I don't even know why we're having this argument. After all, we both know you won't go through with this."

"What do you mean?" I asked.

"Morgan, you love sex. There's no way you could go twenty-four hours without sex, much less over a case. In fact," Reid grinned triumphantly, "Let's test my theory. I won't initiate sex on a case, but if you ask for it, even once, we stop this whole ridiculous argument and go back to shagging whenever we feel like it."

"Oh, yeah?" I asked, gazing at my boyfriend. "You're on."

Of course, when I said that, I didn't realize we were going to have three long cases in a row. When we went to Tallahassee, it was so sudden that I didn't even get to touch my pretty boy before the case started. And Reid was firm on the rules. Once we knew we were going on a case, nothing even remotely sexual could happen between us without me forfeiting. No quickies before we boarded the plane, no making out in the hours between interviews. Nothing.

But just because Reid didn't 'initiate sex', didn't mean he was making it easy for me. Everything, from the way he bit his bottom lip to the cocky way he said, 'I didn't have any plans' before Tallahassee reminded me of everything I wanted to do with him. I had rented that beach house for a reason, damn it! It got to the point that I was focusing less on cases and getting less sleep than I did when we were having sex.

My only saving grace was that Reid and I hadn't had to share a hotel room. The thought of how he would slink into bed, showing me all of his best assets without saying a word, of lying next to him, warm and pliant, and making that breathy little purr he always made before falling asleep, was enough to prove that erectile dysfunction was the least of my problems.

And that's why when Hotch said, "Looks like we'll have to double up." I knew what I had to do. It might make Reid angry, but I had to do it. To save my job, my relationship, my sanity.

"I'm not sleeping with Reid."

I thanked my lucky stars that Garcia's 'dibs!' covered Reid's next comment.

"Oh, yes you are."
