Author's Note: M rated chapter right here, my lovelies! I'd post thank yous and stuff on this, but I'm sat in Costa before work and don't have time! Some of this was kind of loosely inspired from watching Anthony Romero & Austin Wilde's "Austony" video...I'd seriously recommend it if you like adorable gay porn - it's one of the most beautiful things I've ever watched! C: xx


"Oh god, I think something died in my mouth." Stiles complained into the pillow, pulling a blanket up over his head. He heard Derek's snort of laughter and was about to complain when he felt the heavy warmth of Derek's hand between his shoulder blades. "Why'd you let me drink so much?"

"Let you?" Derek asked softly, twitching the blanket aside, moving his hand up to stroke the back of Stiles' neck. "I'm not sure I had any say in the matter."

"Well you should have alpha-ed at me. My brain hurts now."

"That's your own fault." Derek replied, leaning over and gently pressing a kiss against Stiles' hair. "I tried to take a bottle of beer from you at one point but you growled at me."

"Was I being a dick?"

"Little bit." Derek conceded, dragging his hand through Stiles' hair a few times and smiling when he moaned before curling his hand around the back of his head.

"Sorry." Stiles mumbled, shuffling closer to Derek and raising his head slightly to smile at him. "Did you just do your magical taking away pain trick on my hangover?"

"Maybe."

"Mm. Love you."

"Because I took your headache away?"

"For so many reasons." Stiles laughed drowsily. "Of which, yes, that is one."

"Can you stay a while or do you have to go home?" Derek asked, dipping his head to plant kisses across Stiles' shoulder.

"Don't know." Stiles shrugged. "I kind of wasn't supposed to stay here last night, I was meant to go home or go to Scott's, so I'm probably in a fuckton of trouble if my dad's found that out."

"So?"

"So I might as well just stay. The trouble can't get any worse, right?" Stiles smiled up at him again and stretched languidly. "Can I use your crappy shower?"

"Sure."

Stiles grinned happily, pressing a kiss against Derek's cheek and complaining about morning breath and turning away before Derek could kiss him properly. He rolled off the bed, scratching his stomach as he walked out of the room. Derek curled up under the blankets, burying his face in Stiles' pillow and smiling to himself as he listened to the tuneless singing floating through from the bathroom.

"I feel slightly more human now." Stiles announced as he re-appeared in the bedroom doorway a few minutes later, a towel wrapped round his waist and his damp hair plastered to his head. He crossed the room, pulling open the wardrobe and yanking out a pair of sweats from the pile of poorly folded clothes at the bottom. "Can I borrow these? Only it's kind of fucking freezing in your unheated apartment."

"Help yourself." Derek muttered, propping himself up on his elbow and watching Stiles openly as he pulled on the sweats. Stiles pulled the drawstring tight to stop the pants falling off his hips and bent down to pick up his jeans from the floor, pulling out his phone. He started scrolling through his messages as he huddled back under the blankets, wedging his cold feet between Derek's bare legs and tutting as he read a text from Erica.

"Ooh, Scott text me earlier." Stiles commented, scrolling through another message. "Listen to this – 'your dad phoned last night after I got back, got my mom to lie about where you were 'cause I figured you weren't meant to be staying at Derek's. Consider it an extra birthday present but please spare me all the gory details!'. Scott's the awesomest."

"Does Scott normally get all the details when I stay at yours?" Derek asked apprehensively, wrapping his arm around Stiles' waist.

"No! Well, just one time. But only 'cause I was sort of bragging about not being a virgin anymore." Stiles admitted, biting his bottom lip. "Um. That's OK, right? That I told him?"

"Not a lot I can do about it now." Derek complained, burying his face against Stiles' shoulder.

"I didn't tell him the specifics or anything. Just that we'd had sex."

"Specifics?"

"You know exactly what I mean, don't pretend that you don't."

"Good."

"I figured you wouldn't want them all knowing that sort of stuff about you. 'Cause I guarantee Scott would have told Isaac. Didn't want to hurt your alpha image and all that."

"You can stop talking about this anytime you like." Derek muttered.

"Fine. But while we're sort of dancing around that subject, have you thought anymore about, you know, what I asked last week? The birthday present sex thing?"

"Maybe."

"Dude, don't maybe me. You know I can't cope with maybes."

Derek sighed, pulling Stiles closer and kissing his shoulder. "I like when you wear my clothes."

"Way to change the subject." Stiles laughed, rolling onto his side and pressing a lazy kiss against Derek's lips. "So have you? Thought about it?"

"Yes."

"Well?"

"Thought about it a lot." Derek whispered, slipping his fingers under the waistband of the sweats Stiles was wearing and kissing him gently.

"And? Do you want to?" Stiles moved away slightly, the tip of his nose just brushing Derek's as he watched him nervously. Derek paused, his gaze downcast as he stroked his thumb across Stiles' hip. After what felt like an age to Stiles, Derek gave an almost imperceptible nod, closing the gap between them until he could graze his lips across Stiles'.

"Yes." Derek murmured, moving his hand from Stiles' hip to his arm, holding it in place. "But if you use the word awesome right now, I'll kick you out."

"Duly noted." Stiles laughed quietly, letting Derek pull him into a greedy kiss, burying his hands in Derek's hair as he slipped his tongue into his mouth. Derek whined softly as Stiles pulled on his hair, nipping at his bottom lip before mouthing his way across his jaw and down his neck, sucking and licking at a spot low down on his throat where his t-shirt would hide the mark.

"So how's your plan working out for you?" Derek smirked when he finally broke off to catch his breath, hooking one finger under the waistband of Stiles' sweats and running it across his stomach.

"Shut up. It was a terrible plan. Remind me never to go a week without masturbating again." Stiles complained, biting his lip and moaning as Derek's hand dipped lower.

"I told you it was a bad idea."

"You think all my ideas are bad. It's hard to tell when you're making a valid point."

"So you really lasted all week?" Derek asked, pulling his hand out of Stiles' pants and brushing his hand lightly across his stomach and ribs.

Yes. It's been horrible. My balls literally feel like they're going to explode." Stiles huffed, grabbing hold of Derek's hand and trying to force it back into his sweats. "You're being very mean to me, you know."

"Maybe." Derek smirked at him and lowered his head, dragging his tongue slowly across Stiles' chest before biting gently at his nipple.

"Hate you."

"No you don't."

"You're making me hate you."

"No I'm not."

"Want a bet?" Stiles whined, lifting his hips off the bed slightly.

"I'm remembering a conversation from last week." Derek said softly, resting his hand on Stiles' abdomen and rubbing his thumb along his appendectomy scar. "Something about how you were worried that you were going to, what was it, 'blow your load in your pants' I think you said."

"You're not supposed to remember stuff like that and use it against me. It's cruel."

"You're wearing my sweats. I'm not doing laundry just because you can't control yourself."

"I can totally control myself!" Stiles sounded affronted. "I've done the whole controlling myself all week!"

"Thought you might want to wait until...you know." Derek murmured, a faint hint of a blush colouring his cheeks.

"Until you're fucking me?" Stiles grinned, feeling pleased with himself when Derek's blush deepened. "How are you still embarrassed by me talking about sex stuff?"

"Shut up."

"Would you rather I'd said until you're making love to me?"

"Shut up." Derek huffed again, biting Stiles playfully on the shoulder. "You don't need to be a jerk about it."

"You're the jerk." Stiles grumbled. Derek scowled at him for a moment before leaning in to kiss him, tightening his hold on Stiles' hip, his fingers pressing just hard enough that Stiles knew he'd have bruises to show for it tomorrow. "I do though." Stiles whispered around Derek's kiss. "I do want to wait until you're, you know, in me."

Derek made an odd noise in his throat, letting go of Stiles and tugging at the waistband of his sweatpants.

"Did you just growl at me?" Stiles laughed incredulously, lifting his hips off the bed so Derek could pull off his sweats.

"No."

"You did! You totally growled!"

"Shut up." Derek replied gruffly, leaning up to give Stiles a quick kiss before shucking off his boxers.

"I like it when you growl." Stiles continued as though Derek hadn't spoken, stroking the back of Derek's neck idly as he curled up against him, resting his head on Stiles' shoulder.

"I like it when you're quiet."

"No you don't." Stiles smiled as Derek tightened his arm around his stomach. "You like it when I don't shut up."

Derek scowled at him and kissed him roughly, all stubble burn and fingers digging into Stiles' skin in a bid to silence him. "I like when you're like this." He murmured, rubbing his jaw against Stiles' cheek.

"Know what I will like?" Stiles asked mischievously, pressing up against Derek. "I'm pretty sure I'll like it when you're topping." Derek frowned at him for a moment before flashing him a quick smile and giving him a gentle kiss on the cheek.

"Turn on your side." Derek asked quietly, poking around on the chair that served as his bedside table until he found the half empty bottle of lube. Stiles smiled at him and did as he was told, shuffling closer to Derek. He lifted his head off the pillow slightly so Derek could slide one arm underneath his neck, his fingers splaying across his chest. He heard the pop of the cap and shivered in anticipation as behind him, Derek rubbed his fingers together to warm the lube up.

Derek moved closer to Stiles, licking up the back his neck to distract him as he started making little grumbling noises about 'taking too long'. Stiles tilted his head to expose his neck further, moaning as Derek mouthed gently at the juncture of his shoulder and neck; Derek smiled against Stiles' skin, circling his entrance lightly with his fingertip when he was sure Stiles was completely distracted. As Stiles' moans became more urgent, Derek bit down on his shoulder, slowly pushing one finger into him at the same time.

"That was a sneaky little trick." Stiles sighed, pushing back against Derek's finger as he reached one arm behind himself so he could trail his fingers over Derek's ribs.

"You complaining?" Derek asked quietly.

Stiles shook his head, muttering and cursing under his breath as Derek worked another finger inside him. Stiles raised his hand to entwine his fingers with Derek's, keeping his other hand on Derek's hip, afraid that if he touched himself, he wouldn't last more than a few seconds and from the way Derek was slowly and methodically fucking his fingers into his ass, quickly wasn't an option. Stiles could feel his brain itching to blurt out something stupid and mood killing like he'd done a couple of weeks ago, announcing suddenly that Derek 'probably deserved an award for his awesome fingerfucking skills'. Derek had just sighed and rolled his eyes; it had been fairly low on the eye rolling and sighing scale but Stiles still felt as though he'd ruined the mood somewhat. He distracted himself, and his blurty mouth, by using his grip on Derek's hand to tug his arm up, licking and biting his forearm.

"You OK?" Derek asked between kisses to the back of Stiles neck.

"Mm hmm." Stiles replied, rolling his hips as Derek continued to stretch him open. "Feels good."

"Yeah?" Derek withdrew his fingers briefly, to fiddle awkwardly with the bottle of lube, squeezing out more of the thick liquid and liberally coating his fingers. Part of him wished he could be kneeling between Stiles' legs as he fingered him; he loved watching the way Stiles would arch his back and moan, all coherent thought leaving him the closer he got to coming. This felt different though and the thought of pulling away from Stiles right now gave him a little cold feeling in his stomach. He tightened his grip on Stiles' chest, smiling into his hair when he heard the happy little 'oh!' of surprise that escaped Stiles' lips at the gesture. This was closely followed by another 'oh', more of a moan than anything else, as Derek worked a third finger into him, making small circular motions with his wrist to stretch and open Stiles further. "You OK?" He asked, his lips pressed against Stiles' neck.

"Uh huh." Stiles nodded, as much as he able to with Derek pressed against the back of his neck. "I kind of...I need you in me. Want you." He murmured, planting fleeting kisses across Derek's forearm.

"You sure?" Derek asked softly.

"I was sure a good week ago when I first asked you." Stiles replied with a smile. "But yeah, very sure."

Derek nodded at him, looking a little unsure as he removed his fingers and propped himself up on one elbow, stealthily wiping his fingers off on one of the blankets and reaching for the lube again. Stiles twisted around, his eyes wide and bright as he watched him coating his cock with lube; Derek dipped his head to press a kiss against the corner of Stiles' mouth, hoping to distract him from staring so intently. His plan worked for all of thirty seconds before Stiles was pulling away and turning on the bed to face Derek, reaching out and wrapping his hand around Derek's as he stroked his dick.

"Are you just going to sit there jerking off for the rest of the morning?" Stiles asked impatiently, squeezing his hand tight and grinning when Derek gave a little grunt of annoyance. Derek batted his hand away and grabbed the lube, squirting out a healthy amount, before slipping his fingers into Stiles one last time and slicking him up.

"Ready?"

"Hell yes! Get on with it!" Stiles laughed.

"No." Derek mumbled as Stiles made to turn onto his stomach. "Please? I want to be able to see you."

"Pretty sure you'd have been able to see me." Stiles shrugged, turning back over to face Derek.

"You know what I mean. I want to be able to see your face."

"Works for me." Stiles smiled sleepily, opening his legs wider to make room for Derek to kneel between them, making grabby hands at him as he tried to pull him down on top of him. Derek batted him away, shuffling closer, gripping the base of his cock as he lined up and pushed into Stiles, his pace agonizingly slow. He stopped dead when Stiles winced slightly.

"I'm...it's OK." Stiles whispered, running his hands up and down Derek's arms. "Don't stop."

"Does it hurt?"

"Little bit." Stiles admitted, shifting around slightly and wincing again. "Not bad enough for me to want you to stop, trust me."

Derek nodded and leant down to kiss Stiles, his muscles bulging as he bracketed his arms on either side of Stiles' head. He pushed forward a fraction of an inch as he felt Stiles' tongue ghosting across his lips, opening his mouth and letting Stiles take control of their kiss as he continued to slide slowly into him.

"Oh, fuck." Stiles moaned when Derek finally bottomed out and went still. "Fucking fuck."

"You OK?" Derek asked, curling his hand around the side of Stiles' face and stroking his cheek bone.

"Very OK. Just feels weird." He looked up at Derek and smiled reassuringly. "Good weird. Very, very good. You can move, if you want." He added, watching Derek as he bit his lip nervously. Derek smiled shyly at him and pulled out slightly, closing his eyes as Stiles made a soft whimpering sound; keeping his eyes closed as he slowly pushed back in, worried that if he looked at Stiles instead of just listening to the wrecked little noises he was making that he'd lose all self control and come within seconds.

Stiles gasped as Derek started slowly fucking into him, keeping up his slow, slow rhythm as though he were afraid he'd hurt him if he went faster. He ran his hand up Derek's arm before curling his hand around Derek's jaw, enjoying the feel of his stubble beneath his fingertips.

"Stiles..." Derek murmured, turning his head slightly to press a kiss against the palm of Stiles' hand. "Love you."

"You can't say stuff like that to me!" Stiles complained light heartedly, lifting his legs and wrapping them around Derek's waist, pulling him close. "Not when you're fucking me. It's too much for my fragile brain to cope with."

Derek frowned, moving until his chest was flush with Stiles' and kissed him passionately to silence him; Stiles smiled into the kiss, wrapping his arms around Derek's neck so he couldn't move away. Not that Derek showed any sign of wanting to pull away from him, Stiles realised as they continued kissing, his tongue caressing Stiles' own. The way in which Derek was lying on top of him made the angle a little awkward, his thrusts a little more shallow than Stiles would have liked and there was no way he could get his hand in between the two of them to touch himself but he didn't care, feeling far more turned on by the sheer closeness and intimacy than anything else.

"Do you want..." Derek started as though he'd read Stiles' mind, taking his weight on one elbow and running his hand down Stiles' side to stroke his hip.

"Nuh-uh." Stiles mumbled, tightening his arms around Derek's shoulders and pulling him close again until Derek's chest was once more flush with his. Stiles moaned happily; his cock was sandwiched between the two of them, Derek's ridiculously muscled stomach creating a delicious friction that Stiles knew was going to push him over the edge sooner rather than later.

Much, much sooner, he thought as Derek rubbed his thumb across his bottom lip; Stiles extended his tongue slightly and licked it, chasing after Derek's hand to press kisses against it. Derek gave a short huff of laughter and shifted his weight slightly; Stiles flinched as he felt Derek's cock brush over his prostate, bucking his hips up against Derek.

"Don't you dare fucking stop." Stiles hissed as Derek hesitated and gave him a slightly panicky look. "Just...don't."

Derek nodded, once before resuming his previous rhythm, moving slightly faster as Stiles' breathing became more rapid, little whimpers escaping his mouth every time Derek's dick skated across his prostate. Suddenly, like a punch in the gut, he was coming hard and twisting his hands into Derek's hair. He pulled Derek into a desperate, sloppy kiss, fingers twisted in his hair to stop him from moving away; Derek's own orgasm followed a few seconds later and he gave a grunt of surprise as he pushed hard into Stiles, his cock twitching. He felt Stiles' hands slip from his hair, his arms wrapping around his shoulders as he tried to catch his breath. A few minutes later, when the light headedness had worn off he realised he was still crushing Stiles against the bed and half slipped, half pulled out of him to lie next to him on the bed. Stiles made a dejected noise and immediately snuggled in to him, wrapping his arms and legs around Derek as though he didn't intend to let him get away again.

"Not that I'm trying to inflate your ego or anything, but that was awesome." Stiles smiled as he planted happy little kisses across Derek's shoulder and chest. "You should top all the time."

"Don't want to." Derek said quietly, his hand finding it's way into Stiles' hair, as it so often did when they were lying together. "I still prefer it when you do."

"But...but it was awesome!" Stiles complained, smirking when Derek gave a little scowl at the word. "You're like the king of sex or something! Are you seriously telling me I'm not getting that again?"

"No. I'm just saying don't expect it all the time." Derek replied, pressing a kiss against Stiles' temple. "King of sex?"

"Yep. I was going to get you a crown and everything." Stiles grinned. "Why'd you never tell me how weird it feels afterwards?" He asked, squirming around and screwing up his nose as he hid his face against Derek's shoulder.

"Huh?"

"You never said how weird it feels when you've got come in your ass." Stiles huffed; Derek could feel the heat of his blush where his face was pressed against his shoulder and laughed softly.

"Because I wouldn't actually say something like that out loud. I'd just think it to myself."

"Only because you still get embarrassed talking about sex things." Stiles pointed out. "All I'm saying is that it feels weird." He grumbled, lifting his head slightly and glaring at Derek. "I'm not complaining, by the way. It feels weird, but it's still like, oh hey, reminder that Derek just fucked me."

"You know there are still words coming out of your mouth?" Derek sighed, tugging gently on Stiles' hair.

"You know you can suck my dick?" Stiles retorted.

"Maybe later."

Stiles sighed loudly and dramatically as he checked his watch before curling back into Derek's hug. "I'd totally take you up on that offer but it's like nearly 1 o clock and I probably need to go home at some point."

"Oh."

"I don't want to go." Stiles complained, pulling one of the blankets up over his bare shoulders and snuggling closer to Derek. "I want to stay in bed with you for the rest of the day."

"I want you to as well." Derek muttered, trailing his hand through Stiles' hair. "I could come over to yours later if you want?"

"When don't I want?" Stiles laughed as he rolled over and out of bed, searching for his clothes on the bedroom floor. "You can hang out after you drop me off if you want, be my dad's excuse for ordering takeout again."

"Maybe later." Derek replied as he got out of bed and crossed to his wardrobe. "Is he working today?"

"Don't know. Want to stay over if he is?"

"Yes." He pulled on a long sleeved t-shirt and turned to see Stiles watching him, nervously chewing on his bottom lip as he fiddled with his t-shirt. "What's wrong?"

"Nothing! I was just thinking stupid things."

"What stupid things?"

"Things that freak you out." Stiles sighed, picking up his leather jacket from the floor and shrugging it on; out of the corner of his eye, he noticed the happy smile that flickered across Derek's face at the sight of it.

"Are you going to tell me the things?" Derek asked, quickly covering the distance between them and pulling Stiles into a hug.

"It was just stupid, just me thinking about how I want to be here with you all the time. It makes me sad when I have to go to sleep on my own." He shrugged, a pink flush appearing on his cheeks.

"That doesn't freak me out." Derek assured him, kissing him tenderly. "I like falling asleep with you. I sleep better when you're here. Less nightmares."

Stiles made a awkward choking noise in his throat, squeezing Derek tightly and pressing a kiss against the side of his neck. Derek tightened his arms around Stiles' shoulder, breathing in the comforting smell of him as Stiles rubbed his lower back through his shirt.

"Come on." Derek muttered at last, disentangling himself from Stiles and crossing to the door. "You better get home before your dad turns up here looking for you." He hustled Stiles out of the apartment, refusing Stiles' pleading request to be allowed to drive the Camaro home as an additional birthday present, asking Stiles pointedly if he also wanted a speeding ticket as a birthday present. Stiles pouted for a few minutes before distracting himself with the radio, messing with Derek's pre-sets again as he chattered happily all the way home.
