Ok, This isn't my first story exactly, but it is the first story that I'm posting that is more than a few hundred words. So here's to the first of hopefully many stories to come. Well, if you like it anyway. Part two is already started so hopefully there won't be a long wait. Please review and share with me what you thought. Enjoy.

Disclaimer: The only thing I own is the plot of this story. I do not own any of the characters or anything in relations to MTV's Teen Wolf. You can bet if I did, Sterek would already be canon.

"My sister! You killed my sister!" Screeched the banshee witch chick as Stiles pulled an unconscious Issac out of the once burning magical ring. Thankfully it had stopped burning when Derek had ripped the banshee witch's sister's throat out. With his teeth, Stile thought to himself. Derek placed himself between the two teens and Banshee Witch, still half changed, eyes flashing red, and growling. "Your kind should know better than to attack part of a pack and not suffer the consequences."

Banshee Witch looked furious, but seemed to think better of attacking an Alpha head on. A sly smile spread across her face that looked extra creepy with the whole crazy eye thing she had going. She raised her hand pointing in Derek's general direction. "This act will not go unpunished." Her voice was low and took on a strange quality that Stiles took a moment to place.

Stiles barely got Derek's name out to warn him the witch was shouting "RenatusLiberi!" and a blue spark flew from the woman's fingers and right past the werewolf's shoulder. It hit Stiles square in the chest sending him flying backwards. In the time it took Derek to realize what had happened and lunge at the woman, she was already disappearing in a ball of smoke. Derek landed hard on the cold ground, his landing only softened by the pile of fallen leaves that layered the ground. "Dammit." Stiles could hear him yelling and heard a rustling of leaves as Derek appeared at his side. "Stiles, are you ok? Talk to me? What's happened?" The spell had officially knocked the wind right out of Stiles as he'd been thrown into a tree a few yards back, but other than being out of breath and a nasty bump on the back of his head, he would be fine. He told Derek as much as soon as he got enough breath back to do so. "What was all the flashy light show and all the ominous threats of 'she will be avenged' if all she did was throw me back into a tree? And how the hell did she miss you? You are like a walking mountain of muscle. Seriously, why is it always me?"

Derek only smiled at Stiles ranting. "Well, I'm glad you're feeling better." He said as he pressed a kiss to Stiles' temple. "And I did tell you becoming an Alpha's mate would put you in a lot more danger." Stiles just huffed out a "Yeah, but who could stay away from you?" before firmly planting his own kiss on Derek's lips. He could feel Derek's smile through the kiss and Stiles' came up to match it. "Please guys. I thought you agreed to play it down in front of the rest of us." came the whiney voice of Isaac from a few feet away as he finally came around sitting up slightly. Stiles pulled away slightly, but kept his hand on the back of Derek's neck. "Hey, I just pulled you from a burning ring of fire and magic to save your wolf-y ass, I will kiss my boyfriend and you will shut up about it." He pressed another, slightly more passionate kiss on Derek's mouth before breaking it to take Derek's offered hand. Standing hurt a bit, but he covered it by stretching. "Let's find the others and get the hell out of this forest. God I'm really starting to hate this forest." He started walking in the direction of his Jeep and after a moment's pause, he heard the other two following.

Stiles got home at almost midnight that night. He'd been held up by the pack because they had all wanted to know what he'd been doing while he was away at college. The rest of the pack had just chosen to go to the near-by school of Beacon Hills University. Stile on the other hand had the grades and the scholarships to go anywhere he wanted. Stiles didn't really want to be too far from the pack but still opted for the slightly farther away campus of a more prestigious University. Instead of a three hour drive, it was more of an eight hour drive back home. But it was still a drive he made willingly whenever he was needed or had the time. His last term had just ended and he had about a month now before his new one so he had made the drive back to Beacon Hills to be with his father and the Pack. Derek had offered him a place at his newly re-done family house where he had plenty of spare rooms, but his father had insisted that he stay with him. Not that Stiles minded, he'd missed his dad a lot, but Stiles felt that his dad was still not quite comfortable with him going out with an ex-accused murder. So Stiles wasn't too surprised when he pulled into the driveway and saw that the light in the living room was still on.

Stiles gave an exasperated sigh as he got out of his Jeep and walked through the front door. "Why are you still up?" Stiles asked before his dad could say anything else. This got him a disapproving stare and a raised eyebrow that the sheriff only reserved for his son. "Why were you out so late? I wouldn't need to stay up if you came home on time."

This made Stiles crack a grin. "Dad I'm 19 now, almost 20. I don't need a bed time. I was out at Derek's house with everyone because seeing as it's my first day back in a few months they kind of wanted to see how I'd been doing. Crazy thought I know but hey that's my life." He wasn't being completely honest; he'd been back less than a month ago to help the pack deal with a territory dispute between the pack and a clan of elf-ish creatures. His dad knew about the supernatural aspect of his life (after he'd guilted him into spilling everything after one such event that had almost cost him both of their lives), but his dad still tended to worry about him too much, so he still didn't tell him about every little nuisance that came into town. Maybe it was just an old habit left from the old days.

Regardless, his father sighed and stood up from the chair. "I guess you're right, but next time a call or something might be nice." The sheriff walked over to the stairs and gave Stiles a hug on his way up. "Don't stay up too late now." He called as he disappeared up the stairs.

Stiles woke up to another burst of nausea. The path to the bathroom from his bed was now a little too familiar as he ran, hand over his mouth, to the toilet… again. It'd been like this for a few weeks. The strange thing was it was usually only in the morning. By around ten o'clock the worst of it was usually over and he could go about an almost normal day. Well except that he felt even more tired than usual. Stile had originally thought that he had the flu or something, but as it persisted he began to worry. He'd even gone so far as to go on WebMD to see if he could figure it out. It had said he had a brain parasite from Africa, which sadly was only the second most ridiculous answer after it said he was pregnant.

But coming up on day eight here and still no change, Stiles was starting to wonder if it was the magic Voodoo light that Banshee Witch had thrown at him. In comparison, the African brain parasite was looking pretty good. At least he had something on that. At least it was normal in the non-supernatural way. Instead of stressing about it alone in his room, Stiles finally decides that talking to Derek may be the best idea at this point. His dad was a work so he sent a quick message to him before heading out to his Jeep. No point worrying his dad if this turned out to be worse than it looked. He started his Jeep and took off towards Derek's. Please just let it be the parasite, he thought.

"Why didn't you come to me sooner?" Derek asked the worried look on his face not quite matching the anger in his tone. Stiles shrugged and opened his mouth, but Derek continued before he could get a word in edge-wise. "Do you know how serious this could be? That witch could have put any number of spells on you? Could have done a lot of damage to your body and you just now come to us? To me?" Stiles just stood there staring sheepishly at the ground. Derek hated the idea of anyone getting hurt in the pack, but when it came to Stile he was really close to over bearing. "Well, I'm here now, so how about we figure this out instead of yelling about how stupid I am?"

"He's got a point." Came Erica's voice from the other room. She and Isaac practically lived here when they weren't at school.

"You're opinions are not needed, thank you Erica." Derek practically growled. Then he was grabbing Stiles arm and leading him out the door.

"Hey wait." Stiles protested. "Where are we going now?"

"We're going to see Deaton?"

"But why? Why not a proper doctor?"

"Because if this does turn out to be some supernatural thing, a 'proper doctor' probably wouldn't be able to handle it."

"Oh." Was all stiles responded because yeah that made sense. That was actually pretty sound logic. So, he let himself be dragged along to Derek's Camaro.

The good doctor was thankfully pretty free today. He took stiles and Derek into the back as Derek explained what had happened. When he was finished Deaton looked at Stiles like he could possibly distinguish the problem just by looking at him; which, hey, maybe he could. Stiles had seen stranger things. "So you say that your Stomach has been the main source of trouble for you?" Stiles nodded and Deaton went over to the corner to pull out a white machine about the size of a bread box, except it had a TV screen and a wand-like thing attached to it. "Well, you said you hit the tree pretty hard, so the nausea could be from a severe concussion." Stiles didn't need to look, the glare Derek was shooting at him could bore a whole in the side of his head. "But," the good doctor continued, throwing Derek an equally calming look, "I'm going to use the ultra-sound machine first to see if there's any blockage in the intestinal region. Stiles I'm going to need you to take off your shirt."

Stiles did so with little hesitation, it's not like either of these men hadn't seen him naked before. "So," began Stiles as Deaton started rubbing the strange green-ish blue gel on his stomach "Why does a vet have an ultrasound machine anyway?" Confidant that the gel was spread well enough Deaton reached out for the wand thing and pressed it against Stiles' abdomen.

"Well I guess for the reason most other doctors have ultrasound machines. See how a mother's doing with her puppies, look for ruptured organs, and occasionally look for abnormal gro-" Deaton's hand stopped moving for a second, his gaze intensely focused on the black and white image on the screen. To Stiles it looked like any other gray blob that had appeared on the screen, but something about this gray blob was apparently different, and gray blobs were not supposed to be different. Stiles did not like different gray blobs.

"Um, Doc, what's wrong there?" Stiles voice was a bit strained as he craned his neck to get a better view of the gray blob on the screen. Derek appeared at the vet's shoulder and stared at the blob as well. They shared something in a hushed whisper and Stile was seriously starting to feel left out. "Come on guys." Stiles whined because it was better than letting the fear crawl into his voice. "It's my body; if there's something wrong I think I deserve to know, don't you think?" Both men turned to look at him as if it was amazing he was still here. Not even in the 'oh my god I'm just so happy you're alive' way, but the 'you belong in a freak show' kind of way. Stiles could tell the difference because he'd gotten so much of the latter and not so much of the former. Feeling really uncomfortable all of the sudden under the overpowering looks of these two men, Stiles grabbed a towel off the table and wiped the goo from his stomach and quickly put his shirt back on.

When he looked back over at Derek and Deaton, neither had moved, but Derek had noticeably paled. "Ok guys, you are officially scaring the crap out of me so either tell me what's going on or I'm going to leave right now."

Derek finally broke, taking slow careful steps towards him like he might explode if he moved too quickly. He stood in front of where Stiles was sitting still on the cold examining table. "I need to check something." Derek said quietly, asking for permission. Derek never asked for permission. This scared Stiles more than anything else that'd happened before, but he nodded anyway. Still moving slowly, Derek place his ear to Stiles' chest, listening to his steady heart beat and easy breathing, as if committing it to memory. Then he moved lower, to where Deaton had held the ultrasound wand. After a second of listening, Derek jerked back, the fastest he'd moved since the whole mysterious gray blob thing. "Stiles," he said slowly in a low tone, "you have two heartbeats."

An almost hysterical trill of laughter bubbled up then. "So, what I'm a Timelord now? Cool do I get a TARDIS?" Derek looked at him, one confused eyebrow rose, obviously not getting the reference. "No, Stiles, I don't think you understand. You have two separate heartbeats inside you. Your's," he jabbed a light finger at his chest right where his heart would be, "and someone else's. His finger lowered pointing at Mysterious Gray Blog territory. "Stiles, I-I think you may be…. pregnant." And Stiles most defiantly did not faint then. His body had just decided to take an unscheduled nap at that exact moment. Or maybe it was the head trauma from earlier that was finally catching up with him. Either way, it had nothing to do with the fact that he now had a living thing growing inside him. Nope nothing at all.
