A/N: This is my first full length Supernatural fanfic and has been in the works for many months now. I hope you enjoy it. This chapter is a little shorter than what I usually write, but upcoming chapters will be lengthier.

Chapter One: A New Case

Dean began stripping the small newspaper cuttings from the wall and tossed them into the nearby trashcan. His and Sam's latest case was over. Here, smack bang in the middle of Illinois, the Winchester brothers had investigated a strange case indeed. Men had been found dead with strange symbols carves into their flesh, mutilating their bodies. It was later revealed that these men had been sacrifices to a demon group who could promise eternal life. Each demon, thankfully, had been exercised and sent straight back to hell.

"I think we've got a new case already," Sam said loudly as he entered the motel room door. His eyes were practically glued to the front page of a newspaper. "I can't see how we didn't see this before. Apparently, four young women have all been found dead in their homes. But the weird thing is," Sam explained, stopping a moment and turning his head on a side, puzzled by the descriptions of the causes of death. "They all died from childbirth so it seems."

"Childbirth?" Dean asked, looking up from his task at hand.

"Yeah…they were all found in a pool of blood which came from their wombs, showing signs of childbirth, only, get this, none of them were pregnant. Two of them didn't even have partners."

"Check it out?" Dean asked, raising an eyebrow.

"I should think so. That doesn't sound normal to me, Dean," Sam said, tossing the paper across the neatly made bed.

"Where is it?" Dean asked.

"Connecticut," Sam replied. "All victims lived within a ten mile radius of one another. All came from Danbury and the surrounding area."

Not long after the discovery of the new case, Sam and Dean packed all their belongings away into their bags and vacated the room where they'd remained the last week. The room had been cold each and every night due to the lack of heating and the hygiene in the bathroom left a lot to be desired. To say the brothers were happy to be moving on to somewhere else was quite an understatement.

Dean glanced around the room quickly, rolling his eyes at the damp patches on the large cream wall behind the headboards of the beds. This had to be the grottiest motel they'd stayed in during the last year of being out on the hunt. But at the moment it was all Dean could afford. Most of the fake credit cards in the trunk were maxed out and this last one, which had been made out to a Mr. A. Truman, only had a few hundred dollars left on it. All the late night poker games that Dean had played and won, even the winnings were nowhere near enough to keep him and Sam in a motel for a week.

Before leaving Illinois that bright, yet cold morning, Dean made sure the Impala's tank was full of gas. His breath flew by in the late January wind as he filled up the tank and watched other cars pull in and out of the station.

Sam remained in the passenger seat reading over articles on the Internet, finding everything so much more mystifying. After tapping into police files, he'd found quite graphic photographs of the four victims. Each woman had been between the age of twenty and thirty and had been found practically drenched in their own blood from the waist down. On one photo something immediately stood out to Sam. He frowned and zoomed in the image, noticing what seemed like claw markings on the wooden floor beneath the woman's twisted body. He turned his head on a side, inspecting the markings.

Soon the car door opened and Dean dropped himself down into the driver's seat, holding two white paper bags, and shut the door behind him. "There's no way this is normal," Sam said quietly, turning his laptop to the side and showing his brother the images.

"Is anything 'normal' which we hunt?" Dean asked sarcastically and then he glanced across at Sam's open laptop. He grimaced slightly, and for a moment didn't know how to respond; should he be completely disgusted or use some smart ass gag to lighten the mood. "You're right, there's no way we can pass this one off," he said finally, losing any appetite he had to eat the breakfast he'd moments ago purchased for him and Sam. He tossed the wrapped sandwiches onto the back seat and turned on the car's ignition.

The drive was quiet and boring as they travelled down highways, stopping only once on their way for dinner, which happened to be in some crappy diner on the outskirts of the state they were headed for.

Dean and Sam sat opposite one another, eating a burger and order of fries each. Sam, as usual, was tapping away on his laptop searching the net, rubbing his brow in confusion at the very thought of this new case. Dean was well away, exchanging smiles with a pretty blonde who was seated a few tables away.

"I think I've got it!" Sam exclaimed, his head shooting up and his gaze instantly connecting with his brother's. "The incubus has the ability to seduce women and does this in order to spread its seed and help produce demon-human hybrids," he read out loud from the laptop screen. "Wikipedia does come in handy for some things, I suppose."

A nearby waitress frowned at the brothers after hearing their conversation. She placed her hand on her hip and for a moment stopped cleaning the table she was working on and looked up. Dean instantly spotted her and knew they were drawing attention to themselves. "Oh, it's for a college paper," Dean said quickly, smiling nervously at the waitress.

"Yeah," she scoffed, turning on her heel quickly and walking back the way she'd just come, heading down the lines of tables.

Sam continued reading off the article to Dean, explaining about how an Incubus blends in, taking the shape of a human man and then seducing women.

"Dude, I'm eating here, you mind?" Dean asked suddenly, pointing to his half eaten burger. "Do you always have to go into the technical, gruesome details when I'm hungry?"

Sam merely smiled and continued tapping away at his laptop for a few more minutes before closing it and concentrating on his own meal. He took a few bites and then realised something. "I just thought. Some legends say that an Incubus and Succubus are the same creature and can switch sex so to speak. I'm sure I've read about it before."

"That's kinda sick," Dean said, chewing absently on some fries. "Bisexual, cross gender demons. Me and Dad hunted a Succubus, but we never came across anything saying they could change into the male."

"It's just myth, Dean. Some say it was so the female could take the seed of human men and then as the male pass it on to human women."

Dean was starting to get irritated and shoved his food away with a disgusted sigh and sucked on the straw in his drink cup. "I guess it's a way to breed more demonic bastards," he mused, watching the pretty blonde woman who was sat directly behind Sam a few tables away.

"And this is obviously what's happening to the women. They're giving birth to the result of their encounter with the Incubus," Sam concluded.

Sam and Dean crossed the parking lot to the Impala and jumped in quickly, rubbing their cold hands tightly together. Sam immediately began his search for the addresses of the four victims. "I've found something," Sam said suddenly, straightening up in his seat.

"What?" Dean asked sternly, putting his foot down and going about twenty miles over the speed limit. "Fucking jerk!" he shouted suddenly as he was cut up by a car full of young guys. He stuck his middle finger up in a rude salute and beeped the horn, gritting his teeth.

"Calm down, Dean," Sam said, his tone growing slightly irritated. "I've found that all the victims were students at the same college. So far, apart from all being women, it's the only thing I can find which gives them any kind of link."

Dean slowly calmed himself back down and eased back into the seat. "The thing surely ain't picky, unless it likes intelligent, educated chicks."

"My guess is, it's someone from the college and is just randomly picking women from there. None of them took the same classes," Sam continued.

"I thought these bastards were cleverer than this. It's leaving a trail behind itself," Dean commented.

Once in Danbury Dean parked the car outside a local grocery store and crossed the street, heading in for a few beers and maybe some things to eat back at the motel…once they'd even booked out a room.

Sam soon walked in behind him and together the two brothers headed to the left most aisle. Dean grabbed a six pack of beers a couple of bags of chips, holding them in his arms.

"Hey, Dean. I just found something," Sam said quietly, not wanting to avert much attention to them both. "A couple of college girls are letting out a room in a small house. They no doubt attend the local college where the women studied. Maybe we should give them a call. For one, it's cheaper than a motel, and two, we get to talk to them about anything weird going on."

Dean stopped and shuffled back a few steps, looking at the small advertisement which had been written in lacy handwriting and pinned up on a board next to the drinks. He looked up at Sam and grinned. "Two college girls? I'm in."
