Author's Note: M rated chapter right here, folks! Might have to change the rating of this for the next chapter because things are about to take a turn for the lemony! Thanks for the reviews, they make me a happy dork! :D xx

"You said you hate me. Before."

"I also said it's complicated." Stiles shrugged, taking several steps closer to the bed, still smiling worryingly. "Doesn't mean I don't want to kiss you. Or, you know, whatever."

Derek blushed as Stiles cocked an eyebrow and smirked at him, deciding he wasn't going to focus on what 'whatever' might entail right now. He'd be lying if he said he didn't want to kiss Stiles right now; he'd been wanting to kiss Stiles since the night the Kanima had trapped them both in the pool, but Stiles had been sixteen then and no matter how much he told himself that Stiles was mature for his age, he couldn't shake the feeling that he would be behaving exactly like Kate if he'd tried anything. He glanced up at Stiles, Stiles who definitely wasn't sixteen anymore, who wasn't the awkward, clumsy kid he'd first met out in the woods.

"So do you?" Stiles asked, taking another step closer and smiling wickedly. Derek swallowed and nodded dumbly, figuring he had nothing to lose at this point. "Fucking awesome." Stiles murmured, surging forward and quickly closing the distance between them. He wasted no time in straddling Derek's legs, snaking his arms around his neck.

"Are you sure?" Derek started to ask as Stiles watched him intently for a few seconds. Stiles didn't reply immediately, just leant forward and captured Derek's lips with his own. Derek tried and failed to stop the little moaning sound that escaped his mouth as Stiles parted his lips, his tongue flicking lightly against Derek's own.

Derek put his hands on Stiles' hips, still feeling a little surprised that this was even happening; Stiles moaned at the contact, rolling his hips and grinding down against Derek's rapidly hardening cock as he deepened the kiss.

"Stiles..." Derek murmured, pulling back slightly as Stiles bit down on his bottom lip. "Wait."

"Ugh, what?"

"I – I'm still kind of covered in blood and wolfsbane." Derek mumbled, rubbing his thumb in circular motions on Stiles' hip.

"Huh." Stiles looked down at Derek, taking in the crusty reddish-brown stains on his arms and neck, the faint hint of lilac powder still clinging to his stubble.

"Can this...will you wait until I've taken a shower?"

Stiles shrugged, getting off Derek's lap and flopping backwards across the bed. "My attention span is still pretty shit, so hurry it up." He grumbled, stifling a yawn. Derek nodded, grabbing the pair of sweats he had thrown onto the bed earlier and headed for the bathroom, leaning heavily against the door as he closed it. Thankfully the mirror was still fogged up from when Stiles had taken his shower earlier and he didn't have to look at the mess he was in.

He turned on the water and stepped under the spray. He cursed loudly as the icy cold water hit his skin and heard Stiles' laughter float through from the bedroom; evidently he'd turned the temperature right down when he'd finished in what he undoubtedly thought was a hilarious way. Derek huffed, turning it back up to just short of scalding hot, scrubbing roughly at his skin until the water started running clear, all traces of blood and wolfsbane washed away.

He focused his attention on the bedroom, listening to the sound of Stiles pulling open drawers as he towelled himself dry and rolled his eyes. That was another old habit of Stiles', and Erica's to some extent as well, looking through his stuff. He'd once overheard Erica telling Stiles to get out of his underwear drawer and that he wasn't going to "find the answer to the Derek Hale mystery" in there. He shook his head, throwing the towel to one side and pulling on his sweats before heading back into the bedroom, finding Stiles standing guiltily beside his dresser.

"I know what you were doing."

"Force of habit." Stiles sighed, fiddling with the hem of his t-shirt. "Me and Erica kind of used to do that, you know, before."

"I know. You and Erica were never as subtle as you thought you were." Derek laughed shortly, sitting down on the bed. "She always asks about you, you know? When she calls. I thought you two were friends."

"We were." Stiles mumbled, sitting down beside Derek. "It was just...after you told me to fuck off, it was too hard to be friends with her. With any of them."

"Sorry."

"So you said." Stiles shrugged, looking Derek up and down in a completely unsubtle way. "Want to make out some more?"

"If that's what you want..." Derek started, looking down at the floor. Stiles made a scoffing sound, lying back against the pillows and grabbing for Derek's hand, pulling him down beside him.

"Trust me, I've wanted this for a long time." Stiles whispered, inching closer to Derek. "And yeah, I might kind of still hate you a little bit, but I want to do this more." He closed the gap between them, pressing a surprisingly chaste kiss against Derek's lips.

"I've wanted this for a long time too." Derek admitted, draping his arm around Stiles' waist. "Since..."

"Shh." Stiles muttered, leaning forward and kissing him. "Don't really want to talk about feelings and all that junk."

Derek shrugged, allowing himself to be pulled into a hungry kiss; Stiles moaned into his mouth, grabbing hold of his wrist and rolling over, dragging Derek on top of him. He opened his mouth once more, letting Stiles lick his way in, blunt fingernails digging into his shoulders as he did so; Stiles arched his back, pressing up against him, his semi erect cock brushing against Derek's own.

"Could you just..." Stiles mumbled, pushing at Derek. "Get off me a sec."

"Uh, yeah. Sure." Derek replied, breaking off their kiss and sitting up.

"I just wanted to take my shirt off." Stiles laughed as tugged his filthy t-shirt up and over his head, throwing it onto the floor. "It kind of stinks of forest and blood. I wasn't telling you to stop."

He reached for Derek's hand, entwining their fingers and pulling him back down on top of him. Derek obliged, pressing Stiles' arm down against the mattress, holding him in place as he leant down to kiss him; just before their lips met, he caught the pleased smile on Stiles' face and moved his hand in response, wrapping it tightly around Stiles' wrist.

"Figured you'd be the type to want to pin someone down." Stiles murmured between kisses. "All that shoving me around you used to do."

"Figured you'd be the type to enjoy it." Derek countered, tightening his grip on Stiles and yanking his arm further up the bed. "I could always smell it, you know. The way you used to react to me pushing you around." He leant back in, kissing Stiles hungrily, the way he'd wanted to for years. Stiles squirmed underneath him, making a feeble attempt to pull his wrist from his grip while arching his hips up off the bed.

"You're almost making up for being such a dick to me." Stiles muttered as Derek licked and nipped his way down his neck. Derek huffed against the neck, nipping a little harder. Stiles made an aborted gasping noise, digging the fingernails of his free hand into Derek's lower back as he rutted up against him. He pulled back and looked down at Stiles, receiving a pathetic little whine as he watched him; the sight of Stiles, all kiss swollen lips and flushed cheeks made him throw caution to the wind and he moved quickly, throwing one leg over Stiles hips so he was straddling him. Stiles grinned up at him, raising an eyebrow when Derek grabbed his other hand and holding them both against the bed.

"I like when you're all quiet like this." Derek murmured, rolling his hips and feeling an answering twitch from Stiles' cock.

"You had ample opportunities to make me be quiet in the past." Stiles replied breathily, lifting his knee against Derek's back in an attempt to make him lean down. "You chose not to take them."

Derek snorted quietly in response, rolling his hips again and grinning when Stiles bit his lip in frustration.

"You think you could actually go back to kissing me now? Instead of just being a cocktease?"

Derek leant forward until there was less than an inch between them, Stiles' breath warm against his skin. "Or you'll do what?"

Stiles whined again, lifting his head and trying to capture Derek's lips with his own; Derek pulled back slightly, just out of Stiles' reach and grinned when Stiles' whining noises became an affronted whimper.

"Were you always this much of a prick?" Stiles complained. "I definitely remember you being slightly less dickish."

"Were you always this impatient?" Derek smirked, lowering his head and brushing his lips against Stiles. "Wait, who am I kidding? Of course you were." He tightened his grip on Stiles' wrists and finally closed the gap between them. He'd always found himself holding back when he'd kissed people in the past; the less said about what Kate had expected of him the better, but Nina, the girl he'd been with in New York, had always complained if he got too rough and domineering. With Jenna, he hadn't even bothered trying to explain what he liked, letting her take the lead and do what she wanted with him; it had always seemed easier than arguing. He got the distinct impression from the way Stiles was moaning and writhing underneath him that he didn't need to worry about holding back now.

He bit hard on Stiles' swollen bottom lip again before dragging his nose down Stiles' neck, breathing in his intoxicating scent.

"Freaking werewolves." Stiles said softly, trying to lift his hips off the bed again. "What's with all the sniffing all the time?"

"You smell good." Derek replied, his words muffled as gently kissed Stiles' neck, feeling his pulsed racing beneath his lips. "Always have done." He heard, and felt, Stiles laugh at that, trying to twist his arms from his grip. He grazed Stiles' neck with his teeth, moaning against his skin as Stiles gasped loudly and bit him again, harder.

"So you've got lube, right?" Stiles murmured as Derek nosed at his jaw, encouraging him to tilt his head back further.

"What?" Derek paused, leaning back in surprise.

"Lube, Derek." Stiles sighed, rolling his eyes.

"Uh, yeah. Why..."

"You don't want to have sex?" Stiles asked.

"Um." Derek was annoyed to feel himself blushing; yes, if he was completely honest, he did want to have sex with Stiles. He'd wanted to for almost as long as he'd wanted to kiss him. It had been one of the more awkward things Jenna had screamed at him when they'd broken up, if he'd ever actually thought about her when they'd had sex, or if he'd been thinking about Stiles instead. He'd lied and said he'd never thought about anyone else when they had sex, figuring that telling Jenna that he always let his mind wander to thoughts of Stiles, of the lightly defined muscles of his stomach and the dark line of hair there, the dimples at the base of his spine, of the way Stiles always seemed to have something in his mouth when he was around him. It had gotten to the point that before they broke up, he could barely even get hard without thinking about Stiles instead of Jenna.

"If you don't want to, you can just say, you know." Stiles shrugged. "Not like I'm going to run off crying about it."

"I want to." Derek replied in a small voice. "It's just I've never...you know." He let go of Stiles and flopped down beside him on the bed, ignoring the sad noise Stiles made when he moved.

"Never what? Slept with a guy?" Stiles rolled onto his side and watched him curiously.

"No. Yes. You know what I mean."

"Never?" Stiles asked doubtfully. "I thought you said you were into guys."

"I am. I just haven't had sex with a guy. I gave someone a blow job once." Derek huffed, scowling at the ceiling, figuring that Stiles didn't need to know all the painfully embarrassing details of that incident, because it certainly wasn't one he was particularly proud of. It had happened right after he'd split up with Nina, his first attempt at a relationship after Kate; it hadn't been a good break up, as far as he could tell, with lots of accusations about lack of trust and emotional unavailability. He'd wondered for a while afterwards if things would have worked out better if he'd been able to tell Nina that the reason he didn't trust her and was 'emotionally unavailable' was because the last person he'd slept with had murdered his family. Although telling her would have brought up a whole new set of issues he wouldn't have been able to speak to her about and that she could have been angry about; it was probably better, he thought, that things had ended when they did. Not that he hadn't felt pretty cut up about it and in a truly clichéd move had hit up the bar in an attempt to drown his sorrows. It hadn't really worked, due to his body's unreasonably high tolerance for alcohol, but he had ended up sloppily making out with some guy, who in the low, smoky light of the bar bore a fleeting resemblance to Jared Leto, who he'd always had a bit of a thing for. Sloppy making out had turned into the guy fisting his hand in Derek's shirt and dragging him into the bathroom, and asking if Derek would suck his cock. He'd obliged, only to be told after twenty minutes that "this isn't working for me" before receiving a very patronising pat on the cheek and a "well at least you're pretty" before the guy left, leaving Derek with nothing more than a sore jaw and an even worse feeling about himself.

"Ooh, check you out. One blow job." Stiles grinned impishly. "Wait, are you one of those people who doesn't give as good as he gets?"

"What's that supposed to mean?"

"That you let someone suck your dick but don't return the favour." Stiles clarified, toying with the drawstring of Derek's sweats.

"What? No!" Derek huffed in reply. "I just haven't had that much, you know, sex."

"How come?" Stiles asked, shuffling closer to Derek and wrapping the drawstring around his index finger. "I mean, you've seen you, right? Not even when you were in New York? No one night stands? Nothing?"

"No."

"Why not?"

"I've never slept with someone without being in a relationship with them first." He admitted, scowling when Stiles pulled a face. "What's wrong with that?"

"Nothing! No judging here." Stiles replied. "I'm just surprised, you always seemed more like you'd be the fuck them and leave type. You know, so messy feelings don't get involved."

"Is that what you do then?"

"Not always." Stiles shrugged, letting go of the drawstring of Derek's pants and sitting up. "I've had a few relationships. Just seems like too much hassle though. Plus I really, really like sex. Every time I've been with someone for more than a month or so it stops being interesting."

"Oh."

"Now who's looking all judgey." Stiles grinned, leaning back against the wall. "There's nothing wrong with liking sex. Sex is awesome, so are blow jobs. If I could major in giving blow jobs instead of anthropology, I totally would."

Derek tried to think of a way to respond to that statement but quickly gave up, looking over at Stiles as he put one arm behind his head and shuffled around slightly, getting more comfortable on the bed.

"I'll blow you, if you want." Stiles continued matter-of-factly, scratching his stomach. Derek bit back a moan, trying to pretend that the thought of Stiles giving him a blow job hadn't made his cock twitch in anticipation. "You do want, don't you?"

"Yes." Derek muttered thickly, trying not to notice the way in which Stiles was staring so eagerly at his crotch where his baggy sweats were doing precisely nothing to hide his erect cock.

"You have no idea how long I've wanted to do this." Stiles grinned, moving quickly to kneel between Derek's legs and fisting his hands in the loose material of his sweats, tugging them down lower. Before Derek could offer an opinion on just how long Stiles might have wanted to do this, Stiles' hand was in his sweats, wrapping around his cock and Stiles was smiling his wicked grin again.

"If it's any consolation," Derek replied breathily as Stiles started to stroke his dick unhurriedly, "I've probably wanted you to do it for just as long."

"Cute." Stiles laughed, using his free hand to pull Derek's sweat pants lower and leant down, dragging his tongue slowly up the length of his dick. Derek moaned, fisting his hands in the sheets and biting his bottom lip as Stiles stared up at him though his lashes. Stiles looked immensely pleased with himself and lowered his head further, his cheeks hollowing out as he took Derek's cock in his mouth, keeping one hand wrapped tightly around the base as he started to bob his head up and down.

"You sure you're not majoring in this?" Derek groaned, reaching for Stiles' hair and carding his fingers through it as Stiles gave a peculiar snort of laughter around a mouthful of dick. Derek fell silent, closing his eyes and focusing on the feeling of Stiles' mouth on his cock, his tongue swirling around the head and across the slit. He bit back a moan, arching his back slightly as Stiles dug his fingernails into his thigh, screwing up his eyes in concentration as he took more of Derek's cock in his mouth. Derek was all too aware that he didn't have a great deal of experience when it came to getting a blow job; both his ex-girlfriends, and Kate, who he compartmentalised as something else entirely, had complained about the idea of oral sex, and by the time he'd broken up with Jenna, he'd completely given up asking or expecting. Stiles, on the other hand, appeared to be enjoying himself immensely, if the happy little moaning sounds escaping from his mouth every so often as he sucked and licked greedily at Derek were anything to go by.

He lifted his head off the pillow slightly to watch Stiles, groaning audibly when he saw Stiles rubbing the heel of his palm over his own straining erection. Stiles was clearly aware he was being watched as he looked up suddenly, his eyes meeting Derek's; he maintained eye contact as he swallowed down the last inch or so of Derek's cock. Derek heard himself make an odd, strangled noise, a stupidly high pitched whining sound; Stiles gave another snort of laughter and pulled off Derek's cock with an obscene popping noise.

"You like that, huh?" He smirked before lowering his head again, curling his fingers around Derek's cock, his fist moving quickly as he swirled his tongue around the head. Derek made a little keening noise, lifting his hips off the bed, wanting to feel Stiles' mouth on his cock again. As he closed his eyes, he felt Stiles' other hand moving from his thigh; Stiles stoked his thumb across his balls a few times before moving his hand back towards Derek's ass.

Derek tensed up as he felt Stiles' fingertips brushing lightly over his hole, fisting his hand tightly in the sheets. He heard Stiles mutter "relax" and forced himself to loosen his grip on the sheets. After a few minutes, when he was certain that Stiles wasn't about to jam a finger in him without lube or warning, he did start to relax, focusing on the feeling of Stiles' thumb and finger stroking gently over sensitive skin, sending little shocks of pleasure through him.

"Stiles..." He murmured, tugging gently on Stiles' hair. "I'm close."

Stiles responded by removing his hand, his cheeks hollowing out again as he bobbed his head up and down, sucking hard. Derek opened his eyes to watch just as Stiles looked up at him again. The surprise of this sudden eye contact made him lose the last little bit of control he'd been holding on to and he came hard, thrusting up into Stiles' mouth. He was completely unsurprised when Stiles swallowed every drop, making happy little "mmm" noises as he did so. What did surprise him was that Stiles didn't immediately stop once he'd come, but carried on licking and sucking his cock gently until Derek had to stop him, having become oversensitive to the point of what Stiles was doing feeling nearly painful. When Stiles finally sat up, tugging Derek's sweats back into place as he did so, he smiled happily down at him, his lips wet and swollen, cheeks flushed red.

"Guess I can cross 'give Derek a blow job' off my bucket list now." He grinned. Derek laughed shortly, watching Stiles through half lidded eyes; the pleasant afterglow of his orgasm combined with exhaustion from their encounter in the woods left him suddenly unable to do anything more than grab feebly for Stiles, trying to pull him down beside him.
