Chapter 13 - Only You

A/N: I think this is the last chapter... we'll see. Tell me how you feel about the ending. Terribly sorry about the seemingly gigantic hiatus - I've been rather distracted lately and couldn't find time to write.

"Just breathe, Stiles… slowly, that's it..." Derek rubbed Stiles' back reassuringly and the boy started to calm down, his breathing leveling out slowly.

"What… the hell was that?" He asked, still wide-eyed with fright, his hand pressed up against the base of his throat.

"It looked like you were having a heart palpitation; I've gotten them before from exercising too hard. When's the last time you had anything to eat?"

"I had ummm… pizza with Scott last night but I…" '…threw it up right afterward.'

"Jesus, Stiles, how are you even functioning right now? Your potassium and electrolyte levels are probably all out of whack, and you've been downing alcohol like its water… no wonder your body had an attack." 'I can't believe that I thought he was up to fooling around after what happened last night… I just got carried away. Stupid, so stupid.' Derek wanted to repeatedly crack his head on a blunt object once he had himself convinced that Stiles' heart trouble was his fault.

"Sorry."

"Sorry isn't really going to cut it much longer. You have to stop with this shit; you're destroying yourself. If we're… if we're together, are you gonna promise me that you'll stop throwing up - that you'll stop causing yourself harm?"

"Are you giving me an ultimatum?"

"I care about you regardless, Stiles; but I want you to be healthy. I want you to go back to who you were before all of this started… back to your whimsical, obscenely curious, loyal self… that over-protective, adorably awkward friend of Scott's that deserved the bite far more than he ever did. Seeing you like this – it kills me… it kills your dad, it kills your friends…"

"You think I - I don't know." Stiles looked down, studying his hands, massaging the point where thumb meets wrist.

"You don't know if you can stop?"

"I don't know if I can go back to how things were before. This whole eating disorder has taken over my life. Everything else in the past seems like it was just a dream, a faint memory. I'm just a hollow shell of what I once was, and I can't ask you to love that…"

"No. Don't you dare degrade yourself like that! I can see that you're – I know that you're the same Stiles you were before… You just have to let this go. If you keep doing this you're going to throw yourself into an early grave and I for one am not going to just stand by and let you do it; you mean too much to me. Do you value your life so little? I know of lots of people that would love to have theirs back." He watched as Stiles processed what he was saying, as the boy looked up at him, eyes glistening with tears.

"I'm sorry, Derek… I'll stop. I don't know how, but I will. I don't want to hurt the people around me any more than I already have, and I definitely don't want to die before I even hit 20. I'm too young to die; my life is just beginning…"

Derek let the corners of his mouth turn up into a soft smile, then leaned forward to gently kiss Stiles' forehead. "That's a good start. Come on, let's go downstairs." The man then proceeded to cook Stiles the 'most orgasmiccinnamon french toast of all time', and paired it with a thick, tart raspberry smoothie.

Stiles managed to get back to school that Monday, and Scott made a promise to Derek that he would make sure the boy had lunch and kept it down each day. Obviously Scott couldn't follow him around throughout the entire school day, so Derek had to place a little faith in Stiles. Things on that front seemed to be going well.

Much to Stiles' delight, Derek made a habit out of showing up in his room again every single day. Things were different between the two of them, however. About two thirds of the time they spent together they seemed unable to take their hands off of each other. They were constantly touching, whether it be brushing up against each other, subtly snuggling, or full-on making out all over the house. Derek seemed totally fine with things the way they were, but as time passed, Stiles craved more.'I'm a teenager, what does he expect? I mean, it's been like three months, and we haven't done anything even close to what we did before. How do I even ask him about that?'

He was starting to get antsy, and one night he let it be known. He was trying to take things further, tugging at Derek's pants while they were fooling around on his bed only to have him gently pry his hands away like he had done the past few times. Stiles was more than ready to fulfill all of the dirty tasks he had rambled about that time he was drunk at Derek's house. He'd had enough. He pulled away, visibly agitated.

"What the hell, Derek? Don't you want me?"

Derek seemed taken aback, his mouth hanging open in surprise. "Of course! Of course I want you…"

"Well you sure don't seem to act like it."

"It just seems soon; after what happened…"

"Derek, I'm fine; I've recovered. I was in shock, but the guy didn't full on rape me, he just lied to me and drugged me and took advantage…"

"He almost did, Stiles. You weren't truly there – you didn't see – "

"Shhhh, I don't want to talk about that anymore. It's in the past, along with everything else. Fresh start, remember? I just want to have some fun. I've been eating more and I'm feeling better. I'm ready, Derek…" He stared trustingly into the man's eyes, reaching again to undo the jeans. Derek let him. "I mean… I don't want to think about sex negatively, ya'kno? And I've decided… I've decided that I want you to be my first." He finally got the pants undone and helped the man out of the remainder of his clothing, pausing to kiss him briefly.

"You don't know how much that means to me, Stiles… I'm honored. And I know you're not lying when you say you're ready, I just kind of felt responsible for your… episode last weekend."

"I dunno, Der. If I ever gave someone a heart palpitation via blowjob I'd be pretty proud of myself." Stiles joked, slipping out of his own clothes and crawling atop the alpha.

"You're so fucking adorable, can I just put you in my pocket and carry you around with me?" He watched as a blush crept across the boy's face and he continued, "It's cute when you shorten my name like that." Derek smiled and squeezed Stiles' ass with his hands, eliciting a subtle gasp from the boy. Stiles rolled his hips in a devious manner, keeping eye contact with him. 'God, you're delicious… can't wait to taste…' He allowed his eyes to flash red, giving in to the imprisoned beast's demands. He growled then, flipping them over and grinding his body down into Stiles'.

Stiles moaned loudly, his mouth retaining that surprised O shape, as he let the older man explore his body. They rutted against each other like they had done a few times before, but this time they weren't wearing clothes, this time the sensations were heightened. He responded frenziedly to all of Derek's touches, shivering in anticipation as the man started mouthing his way down the boy's body. 'Shitshitshit, that mouth. Oh goddd, what is he-'Derek had settled himself between Stiles' legs, and was licking along his perineum. This was such a foreign place for anyone to be touching – even Stiles… he'd never experimented with this before – he was a virgin in every sense, and as Derek gently lifted him up 'using his superhuman strength', parted his ass cheeks and started rimming him, he could barely control himself. It felt weird at first, and he was really shy about it, leaning away from the man's face. This was his ass for crying out loud; generally things didn't go 'inside…oh my god, his tongue is… yeah this is a good thing, I'm totally down with this.'

Derek had grabbed his hips lightly and pulled him back, digging his tongue in deeper, trying to show the boy that he had nothing to be bashful about. He removed his mouth, giving the boy's backside a little nip, enjoying the way Stiles jolted his hips in surprise and giggled.

"Are you ready?" He planted a few sloppy kisses on the bare ass in front of him while he waited for a response. He didn't have to wait long.

"Fuck yes, I'm ready. Get it in there," Stiles whispered hurriedly.

"Settle down, I don't want to split you in half, I should prep you first…" He moistened his fingers with his mouth and cautiously slid the middle one inside of the brunette, smiling as Stiles groaned and arched his back. He slowly retracted it almost all the way and pushed it back in, running his other hand up and down the boy's lower back. Much to his delight, Stiles started to thrust back against him, and soon he was able to push another finger inside, scissoring the two before crooking them, searching for that sweet spot.

Stiles never imagined the wolf could ever be so controlled… so gentle. He thought for a moment about how sweet that was before a wave of pleasure crashed over him. "Shit!"

"Did I hurt you?" Derek stilled, staring into his eyes worriedly.

"No! Don't you dare stop!" The man chuckled in response and continued the intrusion, adding a third finger, filling him up. "Ohhfuck-Derek-" Stiles has been sneaky, taking himself in his hand while Derek was preoccupied. As the man pressed his fingers into the boy's prostate again his breath caught in his throat and he spilled, soaking the sheets below him as well as his hand.

"Stiles…" Derek ground out, his senses alight from the scent and sound and 'fuck, he looks…'

"No worries, I'll be ready to go again in five minutes." He felt Derek straighten up a bit, felt the man's thick cock graze against his thigh and he shuddered. What with the man's fingers inside him – it was too much – he wanted more, needed more. "Please, god, just-"

"Shhhhhh…" Derek hushed him, giving his hips a little nudge, prompting him to turn over again. He liked how the boy did as he was instructed without him even having to say anything. "Slow…"

"Mmmh," Stiles whimpered, pressing his hips back against the older man's groin, trying to get closer, trying to feel Derek's - 'Ohmyfuck he's huge' "Come on Der, I want it no-ow!" He gasped as the man started slowly pushing in – bit by bit – stretching him slowly. It hurt. 'I hope this gets better – please tell me this gets better…'

Once Derek was fully sheathed he remained that way, running his hands up and down Stiles' back slowly, trying to relax him. 'He's so tight; even after three fingers. I don't want to hurt him…'

"You alright?" He asked the boy, fighting his instinct to move.

Stiles nodded. He was too flabbergasted to really say anything. 'Relax… Just chill. Calm down. Breathe. Breathe, Stiles. Okay, let's do this. I have an idea.' Without warning, he shifted his hips forward slowly, feeling the mass inside of him rescind a bit. It felt nice. He kept going, pulling his body away almost to the point that Derek slid out – then reversed his movement, pushing his hips back, groaning as he allowed the man's thick cock to fully immerse itself again. He noticed that Derek was breathing rather harshly, noticed that the man's hands were gripping his hips tighter and tighter as he leisurely worked himself back and forth. 'Mental note – let him go absolutely wild in the future – I would imagine he prefers it rough...'

"Stiless…" Derek whispered coarsely, allowing his head to tip back a bit. He was fighting the urge to slam into the boy beneath him, to fuck him hard… to dominate. Not this time though, he would at least let him have this after all he'd been through. He started working his hips opposite Stiles, so that they were slowly meeting and parting, allowing his member to almost withdraw each time. Despite his nagging, primal desires it felt amazing. He could feel the orgasm start to build – it had been so long…

Just then, they heard a door open downstairs. They both paused mid-thrust and looked at each other in alarm.

"HEY STILES, WANNA PLAY XBOX?! I PICKED UP THE NEW HALO!"

Stiles breathed a sigh of relief, 'Thank fuck, it's only Scott! I thought my dad might be home early or something! Derek must be pretty distracted if he didn't hear anyone coming from a mile off! Damnit, Scott! Interrupting my first time? Really?!' Stiles was agitated for a split second before he got a fantastic idea. He grinned devilishly and shoved himself back against Derek, which resulted in the loudest, filthiest moan he had ever heard in his entire porn-loving life.

"OH MY GOD, STILES! YOU GUYS – UUUUGHHH I CAN SMELL THAT DOWN HERE!" He turned and retreated hastily, the door crashing closed behind him.

Stiles chuckled, he could still hear Scott cursing as he fled the driveway.

"You're a terrible person." Derek muttered, finally rocking his hips again.

"I know, it keeps me awake at night."

It wasn't long before they were both a sweaty mess. Stiles' dick had returned to its former glory and was bobbing beneath him. He wanted so desperately to touch himself again, but it was taking all of his focus to hold himself up with his arms – and they were growing tired.

"Turn over; I want to see you…" Derek rasped, sliding free of the boy's body.

Stiles followed Derek's instruction, crying out with delight as he was filled anew. He ran his hands down the older man's abs and slipped them around to grasp 'that well-muscled ass…' watching intently as Derek's cock slid in and out of him.

Seeing the bewildered and lecherous look in those brown eyes drove Derek crazy. He bent forward over Stiles and softly kissed the boy's neck, latching his mouth onto the delicate skin and biting as he rode out the most intense orgasm of his life.

Stiles released the Derek's ass (since he'd been holding on for dear life), and moved to wrap a fist around himself, pleasantly surprised when the man slid down to take his sensitive balls in his mouth. "Oh—"He climaxed a second time, splattering his stomach as Derek looked on with hungry eyes. "Fuck."

"Yeah," Derek replied, collapsing against the boy's messy abdomen.

"So that just happened."

"Yeah," Derek was once again reduced to a man of few words.

"And we probably scarred Scott for life."

"…Good."

And then Derek smiled… it was a wide, devilish, mirthful smile, and it sent a jolt of glee straight to Stiles' heart. There, it intertwined with the amazing, blissed-out high he had from the seemingly perfect first time he'd just experienced, and he felt wonderful for the first time in… as long as he could remember. It was in that moment he realized how precious his life really was… it was in that moment that he finally found happiness.
