Freud called it the id. Some people call them primal urges. Whatever you call them, everyone's got them, those inner demons that hang around in the back of your mind, waiting for your weakest moment to make you do something you'll regret. For the most part, and for most people, they're easily banished back to the dark corner they came from.

What most people don't realize, though, is that those inner demons are just the second soul trying to take control of the body they're kept prisoner in. See, before birth, two souls are in completion for one body. The winner gets control and the loser has nowhere to go but to tag along, forever weakened until both are released in death. Needless to say, the defeated soul is usually pretty pissed off and will do anything in its power to get out or ruin what the victor has achieved.

Of course, sometimes things happen, unexplainable things that cause the defeated soul to regain strength. Then all hell breaks loose.

I know what you're thinking. This guy's nuts, and maybe I am. But tell that to Max. I know when I woke up that morning with yet another naked woman draped over me I had a number of things to tell him, and none of them were less than a PG-13 rating.

I silently swore to myself as I glanced around, trying to figure out if I could get away without waking her. It was always awkward to be left to deal with whatever happened the night before, but if I could avoid having to deal with her and just slip away, it would make everything that much easier. Over the years, I had gotten pretty good at avoiding such confrontations, but that didn't make it any less of a hassle.

The woman moaned in her sleep and rolled over. She was still nestled against me, but she no longer had her head on my chest or her arm around my waist, which made slipping from the bed a hell of a lot easier.

I quickly pulled my jeans on, ignoring the fact that I didn't know where my boxers were. As I pulled them up I noticed the name 'Jennifer' written on the palm of my right hand. Well that was something new. Usually I didn't have the luxury of knowing the women's names, though I had a feeling it was more for Max's benefit than mine.

I grabbed my shirt off the floor and got out of the bedroom without Jennifer so much as stirring. Now onto my next problem, which was figuring out where I was and how to get back to my apartment. That was always the most fun.

I walked down the hall to the living room, trying to get my arms into my shirt while at the same time trying to get my phone out of my pocket. I was so distracted from trying to gather my bearings that I didn't even notice the person sitting at the table in the kitchen until she spoke.

"You know, Eric, when I called you last night with the idea of getting drinks, I didn't expect you to end up drunk on your ass and coming back to fuck my sister," the familiar voice said.

I glanced down at the name written on my hand. Jennifer wasn't the name of the woman who had been in the bed. Jennifer was the name of the woman sitting at the table. The name of one of my co-workers that had my situation been different, I may have asked out on a date. The name on my hand was a warning that Max had once again screwed me over.

I looked up at Jennifer with an open mouth, trying to figure out how to explain myself in a way that didn't sound insane. I had no idea what happened last night, so I had no idea where to even start. "I…I…I'm sorry," I began, deciding that would be a good place to start.

"Why are you apologizing? It's not like you owe me anything. We're all adults here," she replied, not bothering to look up from the paper as she took a sip from her coffee.

"I wasn't myself last night," I said, immediately scolding myself mentally for how lame of an excuse it was.

She just nodded absently, not saying a word. After a moment of awkward silence I took that as my opportunity to leave. A ten minute bus ride later I was letting myself into my apartment.

My roommate Jason was already up, or more than likely still up from last night. He had a habit of pulling all-nighters on Fridays playing Halo or Call of Duty or something. I honestly didn't pay much attention to it since I was only really around for the aftermath.

"So, where'd Max end up this time?" he called from the living room, not bothering to pause his game.

Jason was the only other person besides my family that knew what was wrong with me. It was a genetic thing, something my dad and my granddad had and now I have. Something about our genetics gives our second souls a way to become powerful over time. I had had a normal childhood, but once I hit puberty I had more than the usual changes. That's how long it took for my second soul, Max, to gain enough strength to start threatening my control over my body. Eventually, he was almost as strong as I was, making life an absolute hell. I never knew how long I would be able to keep control, or when I lost it, how long it would take to get it back. So, with the help of my dad, I was able to put some sort of hex on myself giving me control of my body, just as he had done when he was my age. During the day, I'd be me. Once the sun went down, I'd depend on whoever was around to control Max and hope that he didn't do anything to drastic. Of course, it wasn't long after that my dad committed suicide when his second soul beat my mother into unconsciousness with a lamp. That was a real confidence boost.

"Did you ask him where he was going when he left last night?" I asked.

"No, was I supposed to?"

"If you had, you could've found a way to keep me from waking up this morning with Jennifer's sister after apparently making a huge ass of myself last night."

That made Jason pause his game. He turned around on the couch to look at me. "Seriously?"

"Seriously."

"Damn. With how often you end up getting laid, you'd think you'd actually be grateful for the guy."

"Really? Max just ruined any chance I had with Jennifer and the only thing you care about is the fact that he got laid last night?"

Jason pretended he was thinking it over a moment before he nodded. "Considering you really didn't have much of a chance with her to begin with, yep."

"You couldn't have even tried to stop him from leaving?"

"Yeah, I could've. Then again, he could've almost broken my jaw again, so I think it was the safer choice to just let him go. Besides, he stayed here the last four nights. That's got to be some kind of record or something," he said, turning his attention back to the game.

"If he stayed here every night, that would be something worth celebrating," I said, tossing my keys into the bowl on the counter as I headed for the bathroom.

"No kidding. He's way more fun than you are. Having him around more often wouldn't be such a bad thing."

I rolled my eyes, flipping him the bird before closing the bathroom door behind me.
