A/N: Hi again. I just couldn't not write a sequel to One Thing, so I did. And it's a two-shot, with the first chapter being in Stiles' point of view (sort of) while the second, and last, chapter will be in Derek's. Hope you all like it! R&R. Enjoy!

Cousin Miguel

Stiles

"Who's he again?"

Stiles could honestly say that he wasn't prepared for Danny to ask that question. Actually, he was hoping that Derek would go unnoticed, but now that he thought about it, he realized how stupid that idea had been. Danny was gay and Derek was hot. Not that he'd ever tell the older man that, but, inside his own mind, Stiles would admit anything. So, naturally, Danny would notice Derek.

"Uh… That's my cousin. …Miguel." Stiles didn't need to look at Derek to tell he was less than pleased with that name. He could practically feel the irritation rolling off of the werewolf in waves. Did it scare him? No. Not at all.

…Okay, it scared him. A lot. After all, Derek was the big bad sour wolf and Stiles was merely human. Granted, a human that knew a lot more than most teenage boys his age and was, in his mind, a valuable asset to Derek's…uh, pack? Yeah, that sounded right. Kind of.

"Is that blood on his shirt?" Danny really needed to shut the heck up. Like, right now. Stiles knew that he should have thought this through a little bit more, but he had been nervous. Nervous about tracing the text message, nervous about Scott in general, and, more importantly, nervous about the fact that Derek was staying in his room for a while. Stupid Scott and his stupid…stupidness.

"Uh… Y-yeah. Miguel gets these massive nosebleeds. It's really embarrassing. Hey Miguel, why don't you change your shirt?" When Derek's eyes met his, Stiles knew that, had Danny not been there, he'd be up against the wall with Derek's hot body pressing against his own. And he so should not be thinking about that right now. He was on a mission, and he needed Danny's help.

He watched as Derek closed the book and threw it on his bed before he got up and took his shirt off. Without even realizing it, Stiles' held his breath as his eyes raked over Derek's toned body. Okay, Stile wasn't gay; he liked Lydia for Christ's sake! But he did feel…something towards Derek. Something stronger and more arousing than he had ever felt before, even with Lydia.

"Stiles. This? No fit." The tone in Derek's voice told him that Stiles was definitely going to die. Soon. Suppressing the urge to flinch, he merely inhaled sharply and glanced over at Danny.

"Then try something else on." Had Derek not been a big, bad werewolf – or a big, bad person who could beat him up in general – he would have added a 'duh' at the end of his statement. But Derek was a big, bad werewolf who could easily beat him up and, of course, kill him.

Glaring at Stiles, Derek grabbed another shirt. Glancing over at Danny, Stiles noticed that the taller teen was watching the werewolf intently, and suddenly, an idea popped into his head. Granted, it was evil and mean and he'd probably get killed for it later, but it was all he had. How else would he get Danny to trace that text message?

"Yeah. Hey Danny, doesn't that look good on him?" Raising his eyebrows at the goalie, Stiles looked over at Derek and a shiver almost ran down his spine. Although orange and blue were definitely not Derek's colors, the tightness of the shirt made him look…God, there were so many words for it. Hot. Sexy. Gorgeous. The list went on. And, thankfully, Danny seemed to be paying attention to Derek as well. And that kind of made Stiles more nervous and fidgety than usual. Why, he didn't know, but it did.

"That's…uh, not really his color."

So Derek took the shirt off, and Stiles raised his eyebrows once again at Danny. He could tell that the older teen's resolve was crumbling, and fast, and in a matter of seconds, he caved. Stiles grinned and nearly air pumped his fist when he felt Derek's smoldering glare on his and decided to not get too excited over his little victory. Even without Derek's eyes boring holes in the back of his head, he knew that he'd be in for it later on.

It didn't take long for Danny to find what they needed, but when he did, it came as a shock to Stiles, and maybe even Derek, though he couldn't tell for sure. Someone had sent the text from Melissa's computer Beacon Hills Hospital. So, as soon as Danny and Stiles finished their lab work, Derek and Stiles set off for the hospital. The ride wasn't a long one, but it was extremely uncomfortable. Mostly due to the fact that Derek still scared him and he knew that he'd be in trouble for his little shirt stunt earlier. But he wasn't expecting the overbearing silent treatment laced with anger, aggression, and something else he couldn't put his finger on. While the silent treatment laced with anger and aggression wasn't new, the something else part was, and whatever that something else was, it kind of worried him. Like, a lot.

"Who was that guy?" At last, Derek spoke, just as Stiles pulled his jeep into a parking space in front of the Beacon Hills Hospital Long Term Care Center. He was so startled by hearing Derek's voice, laced with anger and…jealousy?

"Uh, that was…was Danny. He's my lab partner for Chemistry and he's the goalie for our lacrosse team. Why?" He glanced over at the werewolf and saw that he was glaring daggers out of the windshield of his jeep. Stiles bit his lip and faced forward, not wanted to directly witness the assault that he knew was bound to come.

"I don't like him. Don't bring him over again and stop hanging out with him." Okay, now that was just ridiculous. Danny was his lab partner, as well as his kind of, sort of friend. Plus, he was on the lacrosse team, so Stiles was going to hang out with him. And he liked Danny; he was nice and not a jerk like Jackson, so Stiles liked him. Derek had absolutely no right to tell him what to do at all, and especially when his friends were involved.

"What? No way! Danny's my friend and lab partner. And he's the goalie for our team, so I can't stop hanging out with him. You know what? Just because you're a big, bad, scary werewolf doesn't give you the right to boss me around and shit like that. You're staying with me because of Scott being, well, Scott, so you should be grateful or whatever. And that means that, uh, you shouldn't boss me around?" Stiles lost his heat when Derek's glaring green eyes met his honey brown ones. Derek growled and moved in his seat so that he was pressing Stiles against the driver's side door, his warm breath caressing his face.

"Do you know that Danny, or whatever his name was, likes you?" Stiles blinked in confusion.

"Huh?" Derek rolled his eyes.

"Before the two of you even entered the house, I smelled him. More specifically, I smelled his arousal and, believe me, it wasn't me that was making him all hot and bothered. His heart was beating faster than it normally should have, and, in case you didn't notice, he stayed close to you when the two of you were working on your lab bullshit. So yeah, I think it's safe to say that he likes you, so stay away from him."

"W-w-what? But that can't…Danny doesn't… He's my friend! I can't…" Derek growled and pressed his lips to Stiles' in a bruising kiss. Stiles' heart leapt into his throat and found himself responding eagerly to the kiss. The weird feelings that had started bubbling up inside of him when Danny started checking out Derek, subsided. Derek's lips were soft and warm and demanding and he absolutely loved it. Unfortunately, it didn't last long, and Derek pulled away, looking a little less angry.

"You are mine. Not his. Mine. Got it?" Stiles nodded and Derek smirked triumphantly.

"You're my mate, Stiles, not his. Do you have a problem with that?"

"N-no." Derek kissed him again and Stiles moaned into the kiss, wanting nothing more than to pull the older man closer to him and never let go. But they had a mission to complete, and they couldn't exactly do…well, stuff, right now. So, just like before, Derek pulled away, licking his lips and looking smug and cocky, and sat back in the passenger's seat.

"Good. Now, call Scott and see what he found out." Groaning and pouting, Stile pulled out his phone and dialed Scott's number.

Although he was Derek's mate, he was still getting bossed around. Typical.
