Stiles took over planning some of the Hale Family Funeral from his dad. The sheriff was trying to make all the decisions for his son-in-law so he wouldn't have to think about it, but Stiles wanted to be in on it to. Despite the fact that Derek obviously didn't hold him responsible in any way, Stiles still felt a little guilty and he felt that this was one way that he could make it better.
Lots of people from the reservation were more than willing to help out. Insurance took care of the money with plenty left over, so Derek wouldn't have to worry about his financial future. On top of that, one of the leprechauns had figured out how to invest, so the sheriff gave part of Derek's money to him and told him to have at it. Leprechauns liked money in any form, and as they weren't much for fighting the clan that lived on Beacon Hills felt like they could participate in the war effort in this way.
Stiles spent a lot of time studying war tactics, looking them up on the Internet and consulting with Rupert. Tokala put him into contact with some people from West Pointe, who were very interested in discussing things with Stiles. He had to keep himself from spilling too many secrets about his kind, but he was more than willing to share anything about the Unseelie that they asked.
School had of course been cancelled, as the humans made their way off the reservation and into the rest of civilization at Tokala's announcement that he was pretty sure they were going to attack Beacon Hills. There were camps of them near the old Hale House, a fact that angered Derek and refocused his efforts on training his pack. They were all focused and coming along nicely, and the Marrok had sent in more werewolves to help out. Apparently, a lot of werewolves had been bitten during the Vietnam War, which was good because Stiles believed that a lot of the newer Wars had not been fought with the same tactics and they would need some things that other people might consider dirty. He didn't think that the Unseelie would understand "civilized war tactics," and that many humans and newer werewolves would balk if they had to do something that would be considered barbaric. He knew the enemy would not hold those same moral opinions.
All of these things did not lead to happy Derek and Stiles times, which was what Stiles found to be the most frustrating thing in the world. Now that he was allowed to touch and taste and feel, there was no time. They still slept together, or more like spent their unconscious times together, because they fell into bed every night exhausted and didn't have enough energy to do more than quickly kiss each other and hold each other tightly before they passed out. He felt guilty for wanting that from Derek when Derek was dealing with so many other things, and he felt guilty for wanting that for himself when he knew that his energies should be spent elsewhere, but damn it all if he didn't just want.
It didn't help matters that Derek was being be his glorified sexy self, all sweaty and muscley and man-like outside while he was training the wolves, or that he would come in and smell all piney and clean-sweaty and just like Derek when they came in to get water. He would give Stiles these 'I'm so sad but I'm happy to see you in my kitchen planning a war' type looks that drove Stiles up a wall, and then go back outside in his long baggy sweat pants that should not be sexy but totally were and work out more of his man pain. Which Stiles was fine with, sure, but he would have preferred some of that man pain worked out on him.
So Stiles continued to plan a war in a state of sexual frustration that Rupert assured him that every general was forced to do, and perhaps if the other side would have just gotten laid more they wouldn't be causing their side to give up getting laid in favor of planning countermeasures against them in the first place.
Stiles conceded that Rupert made a great argument, but it still wasn't getting him laid so instead of answering he just grunted.
The kids, though, the kids were a great distraction for Stiles. Isaac and Boyd both tended to cling to each of Stiles's legs, making walking a difficult task. They demanded stories and cookies, being the high maintenance children that they were, but they usually settled for one or the other. Stiles would try to take a few hours out of his day to set up a kind of school for them, making sure that they were reading at level and doing arithmetic problems that he had to pull out of his head. He had Boyd doing multiplication flashcards and Isaac doing addition flashcards, and he had them practice their handwriting until it was beautiful. He made them read and illustrate their own stories and put those on the fridge with magnets, and Derek would come inside after training every night and declare that his sons were geniuses.
They were calling them Daddy Stiles and Papa Derek by the end of their first week together, and Stiles muttered to Rupert that he and the Virgin Mary had something in common. Derek heard it though, and he frowned a little at the comment, but nothing was done because there was still that huge war thing coming up.
Stiles did like having the kids around, and it made his dad insist on him moving in with Derek so that he could watch his children better. Rupert was not a fan of this plan, but he helped Stiles pack everything up again and move it to what everyone was calling the New Hale House.
A month after the Hale funeral, Stiles was in the middle of reading the Book of Invasions, which was part of the Book of Leinster, one of the most accurate sources he could find on the last Faery War, when Derek pulled him away from his table. Stiles noticed that everyone else had gone away from the house, which was the first time that had happened in forever, and he looked up at Derek kind of confused.
Derek had showered and pulled on a pair of jeans, and he was tugging lightly on Stiles's hand. "I don't know how you want to do this," he was saying, "But I can't wait any longer. I've tried to keep my hands off of you, but there are just things that you're going to have to do as my mate."
Stiles felt confused, but things became more apparent to him as Derek dragged him towards their bedroom.
Stiles would have corrected Derek's assumption that he didn't want to do this, but that would have taken time away from just being given permission to do all the things that he wanted to do to Derek, so instead of protesting he just kissed him in the middle of the hall, as soon as he figured out what was going on.
Derek didn't seem to mind his reaction all that much, and if he was surprised he had apparently decided that reaction could wait for later, too. His hands were too busy tugging at Stiles's shirt, which made a very pretty mess on the hallway floor, and his own shirt, which created a neat kind of symmetry a few feet down on the other side of the hall. Stiles was sure they could admire the artwork in the way that the fabric of their shirts created later, because right then Derek's hand had slid down the back of his pants and was holding onto his ass like Stiles might want to get away from him or something.
Stiles couldn't keep himself from touching Derek, sliding his hand up velvety skin covering hard muscle, shaping his flesh into small mounds to hold onto, licking into his mouth and down his throat in a desperate attempt to find out how he tasted everywhere.
Derek kicked at the doorway to their bedroom, pushing Stiles in and then pushing him up against his door so that Stiles could have some sort of support. Stiles was grateful for it, because Derek was kissing and licking his way down his own chest. "Drop the glamour," Derek insisted, and Stiles complied. He had no idea why Derek liked it so much, but he wasn't going to argue when a man who looked like that was unzipping his pants and pushing them down around his ankles.
Derek licked a bit at his thighs and his hips, and Stiles whimpered from the amount of teasing that was going on down there. He hadn't ever been this hard before, and he was a little worried that by the time Derek finally got to where he wanted him he wouldn't have any control whatsoever.
Derek nudged one of Stiles's legs out of his pants and spread his legs, giving him more access. Stiles threaded his fingers through Derek's hair and whimpered, worried that he was putting a little too much pressure on the other man's head. Derek seemed to like it though, and he stuck his tongue out as he looked up and met Stiles's eyes as he took one long lick up from Stiles's balls to the tip of his prick.
"Fuck," Stiles cursed, staring as Derek took the very tip of him into his mouth and then slid his mouth down, his lips stretching around the width of Stiles's cock. One of Derek's hands reached up and cradled Stiles's balls, smearing the wet from his saliva back to his perineum and rubbing it in with hard, calloused fingers. Stiles's hips bucked, shoving his dick back into Derek's throat and Derek just swallowed around it like it was the only thing he wanted to do in the world. He made a growling noise at the back of his throat, and if Stiles thought he was susceptible to Derek simply talking then he grossly underestimated the impact of having that sound directly on his dick.
Derek let Stiles fuck his mouth for a while, which was good because Stiles really didn't think that he could have stopped himself. He did this amazing thing with his tongue, but then he pulled off of Stiles with a wet popping sound and he pushed him over to the bed.
Stiles stumbled a bit, but Derek was on top of him, biting the back of his neck and licking his way down his spine, his tongue tracing hot wet patterns that cooled too quickly in the air. Stiles was thrusting into the sheets because he just couldn't stop himself, and then Derek licked his way down between Stiles's ass and found his hole.
Stiles had never had anyone touch him there before, and it was awesome. Derek licked around him and then pushed his tongue inside, opening him up with that muscle while occasionally wrapping his hand around Stiles's dick and squeezing lightly, and then he pushed a finger in so he could fit more of his tongue in there, too.
Stiles was grateful that everyone was gone although he was pretty sure they could still hear his moans from miles away. Derek's mouth was wet, and his fingers were tracing patterns inside of him, and his hand was tight around the base of his dick so that he couldn't come. Stiles found himself promising all sorts of retribution on Derek if he didn't let him come, didn't let him find relief, and Derek just kept licking and fingering and tongue fucking his ass like it didn't matter at all.
Stiles almost sobbed in relief when Derek put the tip of himself inside, still holding tightly to the base of his dick. His body stretched around Derek, but he was so relaxed from his earlier ministrations that it just felt right, like Derek belonged inside of him like that.
"Damn, so tight," Derek whispered, sucking praise onto the back of Stiles's neck. He pushed further in, and Stiles felt himself shaking with the need to come. Then it all got worse as Derek hit his prostate.
Stiles swore he saw stars, he felt so full and his legs were spread so wide and Derek started stroking him with his hand as he pulled out. Being filled was almost as bad as when he pulled out, and when Stiles had adjusted Derek went faster.
Stiles was crying by the time that Derek let him come. He was a fucked out mess, his body didn't want to handle everything that Derek was throwing at him, and Derek bit his shoulder as he came inside of Stiles, hurting him just a little.
"Sorry," Derek whispered into his back. "That was supposed to last a little longer. You're just so damn sexy…"
Stiles wiped his face, turning to look at Derek. "I couldn't have handled longer. That was perfect."
Derek smiled at him, kissing his forehead before getting up from the bed to wash off a little. Stiles followed him, and they decided to take a shower almost immediately, and Derek seemed content to just wash Stiles and let Stiles wash him. They stroked each other and kissed and it wasn't as intense as the first time, but there were so many touches that they needed to experiment with, and Stiles wouldn't have given up staring up into Derek's eyes when he was looking at him like that for anything.
Stiles wasn't too sure how long they had stayed in the shower together, but he wouldn't have traded that time for anything in the world when it was over. Derek was a little surprised when Stiles waited until he was wrapped in a towel before taking his face in his hands and pressing a gentle kiss to his lips. "Thank you," Stiles said, "for making that my first time."
Derek looked shocked, "I wasn't sure that you wanted it… that you wanted me…"
Stiles felt his eyes growing round, and he forced himself to blink a few times. "What?"
"I know you got stuck with me as your mate…"
"Oh yes, poor unfortunate me, getting stuck with the hottest Alpha in the world as a mate, who just happens to be my best friend that I'm head over heels in love with. How in the world am I not crying with the agony and unfairness that my life is?" Stiles teased.
Derek looked shocked. "You love me?"
"I thought that was obvious…" Stiles said. "Just like you love me."
"I do," Derek said, quickly.
Stiles smiled at Derek. "What made you think…"
"I just couldn't imagine that you would feel like that, that something like you could happen to me," Derek said.
"Derek," Stiles said, and then he decided that there had definitely been too many words between them, and he settled for just kissing him.
They put their clothing on after that, which didn't get done very quickly because they had to pause every few moments or so for another kiss. Stiles didn't quit whispering that he loved Derek, and Derek kept turning red and at times tried growled at Stiles when he got too obnoxious about it, and even once tackled him to the floor so that he could tickle the crazy out of him.
It didn't work, or so Stiles claimed, but he was pretty pleased that they were dressed and semi-presentable when Lydia came back from taking the kids to the park and out for dinner at a children's pizza place with loud noises and florescent lights.
Isaac and Boyd came running up to Derek and Stiles, throwing their prizes on the floor of the entryway and trying to make them fall over by wrapping their arms around their legs. Isaac was sporting a huge black eye, and Boyd looked vaguely guilty.
"What happened?" Stiles demanded of Lydia.
"One of the cubs said that he could build a better sandcastle than Boyd, and Isaac insisted that he was a… I'm sorry, what did you call him?" Lydia asked.
"A hobgoblin…" Isaac mumbled into Stiles's pants leg.
Stiles tried not to laugh, but he was sixteen and things like self-control were still being learned. "You shouldn't call the other kids names," he tried to reprimand.
Derek growled at Isaac. "You shouldn't let the other kids hit you," he said. "You're faster than a werewolf."
Isaac looked like he was going to cry. "I'm sorry Papa," he wailed, and Derek picked him up quickly and held him to his chest, looking at Stiles completely and totally panicked. Boyd started wailing too, not sure why Isaac was so upset, and so Stiles struggled to pick him up, too.
Lydia just laughed at them as she left them, the traitor, and Derek and Stiles were left bribing their children with ice cream and then putting them into bed with them, where they fell into an exhausted sleep.
"I think that could have been handled better," Derek said, looking at Stiles.
"Maybe," Stiles agreed. "If you have any tips, feel free to share them."
"Maybe we could look up answers in the Internet?" Derek suggested, curling up around Boyd but still facing Isaac and Stiles.
"Maybe we should hire a nanny for all four of us," Stiles suggested, staring back at Derek without his glamour, because that's how Derek liked seeing him.
"That's probably the best idea I've heard all night," Derek said sleepily, his eyelids closing.
"Certainly not the best," Stiles mumbled, a yawn taking over his words.
Derek understood him anyway, and Stiles could tell that he was laughing despite the fact that he was falling asleep. Stiles pulled Isaac closer to him when the boy whimpered a little bit, and after he had whispered some nonsense into the child's ear he relaxed in his Daddy's arms with trust that only a child could have. Stiles looked at his new family, and despite the looming war he appreciated this moment for what it was.
