AN: Ok so biggest apology ever for the horribly long wait. Started school and have been swamped. I can also only write every other week now so updates are bound to be slow from now on. At least once a month but maybe twice if I can stop being exhausted when I get home. But anyways, here's the chapter! Enjoy!


Chapter 11:

I huffed as Derek tossed me onto Stiles' bed. Stiles must be back with Danny otherwise Derek wouldn't have stopped kissing me so abruptly and deposited me on the nearest surface that wasn't his body.

I propped myself up on my elbows and glared at him as he sat in a chair next to the bed but he just picked up a book and opened it to a random page, totally ignoring me. Ass.

Rolling my eyes, I laid back and stared up at the ceiling, stretching my legs out and ignoring the low growl when they flopped into Derek's lap. He pushed them off but I just propped them right back up and I heard satisfying sigh. He pulled the book out from under my legs and set it on top. Whatever. Either way I won.

About that time Stiles walked in, Danny in tow before he fell into his desk chair with the grace of newborn colt. "Hey Danny." I waved, smiling.

"Hey Sarah." He responded then looked to Derek who didn't even look up so Danny just walked over to Stiles' desk. "Now you want me to do what?"

"Trace a text." Stiles said quickly, turning in the chair to face Danny. Well get straight to the point why don't you Stiles.

"I came here to do lab work. That's what lab partners do." Well this was going well.

I turned my attention to Derek. Was he seriously reading that or was he just staring at the page and seeing nothing. I jerked my leg a little and the book wobbled. Derek glanced up with an irritable look and I smiled innocently. He snorted and went back to reading –looking at- the book. I moved my leg again but he didn't even look up. Well that was no fun. I did it once again and the book almost fell off. This time he looked up in exasperation. I smiled again and his face became unreadable, a certain glint in his eyes.

Then I felt the press of sharp nails through my jeans near my ankle, threatening and teasing. And damn why did that have to get me all hot and bothered? They were just claws for goodness sake! His grip tightened and claws pushed through the fabric of my jeans, raking my skin lightly. The sharp intake of breath from me next was totally justifiable. He just smirked, retracting his claws and going back to ignoring me.

Yep. Major ass. Well two could play at this game. I moved around on the bed until I was on my stomach near the edge of the bed and was facing Derek. I glanced to where Stiles and Danny were arguing but they weren't paying attention so I looked back to Derek. He seemed suspicious, watching me from the corner of his eye but did nothing.

I hid my smile and leaned over him, acting as if I was interested in what he was reading. My long hair cascaded down, hiding my hand as I reached forward towards the book, skimming his crotch as it went. The lowest of growls sounded in my ear and I pressed my lips together tightly. Glancing one more time at the two boys, I palmed him experimentally. After a minute his hips twitched and I grinned.

My victory was long lived though because Derek dipped his head and I instantly felt sharp teeth on my neck, scraping lightly. I sucked in a shuddering breath. "Behave." He growled so low in my ear I could barely hear. Then his teeth were gone and he was pushing my hand away. God he was the biggest tease ever.

I leaned back and heard Danny's low voice. "Who's he again?" I casually moved further back on the bed and tucked my hands under my chin, propping my head up as I looked over at the two. This should be good.

"Uh, my cousin. Miguel." I barely disguised my laugh as a cough. Derek didn't seem too pleased about it as he looked up, arching a brow.

"So your brother?" Danny asked me and I couldn't stop the horrified look that crossed my face.

"No. Definitely not. Other side of Stiles' family. Not mine." I explained quickly. Because uhm no way was Derek my brother –well he wasn't Stiles' cousin either but Stiles hadn't done the things I had with Derek so it wasn't dirty or anything.

Danny nodded slowly then looked back to Stiles. "Is that blood on his shirt?" He asked and I glanced over. Oh my gosh how had I missed that? I definitely needed to start paying attention and ask Derek why there was blood on his shirt because that wasn't concerning whatsoever. No not at all.

Stiles glanced over to Derek then back at Danny. "Yeah-yes. Well he gets these horrible nose bleeds." This time I held in my laugh but Derek's expression made it hard. He looked up, face hardened and obviously annoyed. Stiles was in for it. "Hey Miguel! I thought I told you that you could borrow one of my shirts." His eyes darted towards his dresser and I turned to watch Derek. This was good entertainment and hello Derek shirtless. That was definitely something I wasn't missing.

Derek's glare could cut through steel and was definitely wet yourself inducing but Stiles held his ground and Derek slammed the book closed, tossing it to me as he walked towards the dresser. I fumbled to catch it and shot him a look that he didn't see as he pulled off his shirt –and whoa. Thank you Stiles- and started rifling through Stiles shirts. It brought back a memory of him doing the same to me –though it was a much more personal drawer- and I bit my lip to hide my smile. He glanced over at me and for a second his aggravated-I'm gonna rip you apart- look was gone and I knew we were thinking the same thing but then he was looking back through the drawers and the expression was back.

After a second he turned towards Stiles with a shirt in hand. "Uh, Stiles." Derek interrupted whatever Stiles had been saying to Danny and I had to give him props at how calm he sounded. Even though I was definitely more interested those abs of his because damn.

Stiles swiveled in his chair. "Yes?"

"This." Derek held up the shirt in his hand. "No fit." I was perfectly fine with that. Shirtless was a good look on him and there was no protesting from this corner of the room.

"Then try something else on." Stiles had to ruin my little fantasy. But hey this was second best. I was totally fine with Derek modeling clothes. Especially too small, too tight shirts that couldn't help but show off everything. Yeah, totally good with that. He can be like my own personal model or something. In that case he should just take the pants off too…

Getting out of my little la-la-land, I noticed Derek putting on another shirt. An ugly one –orange and blue striped- but another shirt all the same. And it was much too small and much too tight. Again, thank you Stiles.

"Oh hey that one looks pretty good, huh?" Stiles asked and I couldn't stop the small laugh that bubbled out of me, catching a glare from Derek. Then I realized Stiles had been speaking to Danny. Derek was turned towards them, modeling all gorgeously and not even for me and that was totally not ok. The whole point in personal model is the personal and this was definitely not just for me at the moment.

I looked to Danny and yep, he was totally checking my –ok so he isn't exactly my boyfriend… I guess. I don't really know what he is but no matter what he's, uh, mine… I think. So yeah checking out myboy-were-guy… thing. Uh yeah.

Which I mean hey, that's cool because a thing so beautifully muscled like Derek should be ogled but at the same time not cool. Because yeah the whole mine thing. I'm pretty sure he's mine. He made it pretty clear I was his earlier today –which yeah, hundred percent ok with- but was that just show? Didn't think so. So if I'm his then it only makes sense that he, in return, is mine. My theory and I'm sticking to it.

"Uh it's not really his color." Danny said quietly and I laughed again at Derek's sour face. Stiles was so dead after this.

Derek tugged the shirt off, looking like he wanted to destroy the world. "Stiles, none of these fit!"

I decided to put him out of his misery and got up off the bed, grabbing his arm and dragging him towards the door. "Come on. I'll get you one of my uncle's."

I pulled him down the hall towards my room. I had one of his shirts anyways. As soon as we got in though, he forced me against the wall, lips crushing mine. Ok so this was apparently let out frustration on Sarah's lips time. Not that I was complaining. Except it would be kind of suspicious if we just didn't come back so…

"Derek, not now." He responded with a growl. "Later. Just not now." His teeth scraped my lip and I shuddered, steadily losing what little self-control I had. But as soon as I had given in, he pulled away. Oh that gorgeous, taunting asshole.

I glared and grumbled as I walked over to my dresser and pulled out one of his shirts. When I turned back around, he was picking up the box of condoms off the bed. I sighed in exasperation. "Derek-"

But he cut me off. "This isn't where I put these."

I rolled my eyes. "You didn't put them anywhere. You just threw them in here."

"No I made sure I threw them over the bed. I heard them hit the floor." He said and yeah, I was totally not freaking out. Not at all.

"You misheard?" I tried weakly but he shook his head. "So you're saying my uncle saw them?" He just nodded slowly, expression unreadable. "Shit. Oh shit. Ok well yeah that's… that I will deal with later but until then, put this shirt on and lets go back in there and play nice." I threw him the shirt then walked over, took the condoms from him and threw them into my bedside table drawer.

He slipped the shirt on and leaned down to give me a quick kiss. "Maybe he won't say anything." He tried and I snorted.

"He's the Sheriff, he will. I'm just worried about him telling my dad." He tensed at that and I wanted to laugh. Derek Hale was not scared of fathers. I just couldn't see it.

"Your father seemed-"

I cut him off quickly. "Let's not talk about my father. Come on." We walked back to Stiles room and apparently Stiles had been able to convince Danny to trace the text. Well let's be honest here. It was all Derek's glorious body.

Derek and I lounged on Stiles' bed as the two hovered over the computer. I had fixed Derek's hair from its state of sticking up everywhere and was now tracing the veins running up his arms. He didn't seem to mind and even went as far as closing his eyes a couple of times, a low, contented rumble in his chest.

"There." Danny said, interrupting my peaceful thoughts but we both jumped from the bed and crowded around the computer. "The text was sent from a computer. This one."

"Registered to that account name?" Derek asked and I followed his eyes and my jaw dropped. It had to be a mistake. There was just no way.

"No, no, no, no, that can't me right." Stiles murmured quickly. He's right. It couldn't be. Not Melissa McCall. Not Scott's mom.


AN: Ok so sorry I'm having to stop it right there. I wanted to continue but I don't have time to right now. I have to leave my laptop soon and won't have it until next Sunday so I thought I'd go ahead and give you guys what I have now then finish this not this week but the next. Again sorry I've been so slow. Oh but if any of you have a tumblr, you can check mine out, (It will probably be an ass and won't show the link so my url is: sonofabitchjerk (same as the username I have on here.) but yeah that's the easiest way to contact me if you want to know when the next chapter will be up or if you have any question or anything of the sort. Also I wrote little story called All His Fault (check my profile) for the Teen Wolf Fanfic contest but it was too late to enter it so I just shared it with you guys. Oh and while I was writing this chapter, I came up with an idea for another story (another Derek/OC) so you might see that in a couple weeks if I can figure out more of the plot. Ok well I'm blah blah blahing now so I'm gonna stop. Hope you enjoyed the chapter and I'll try to get the next one to you as fast as I can.
