Chapter 48
Derek went for a run. It was a coward move, he knew that, but he needed to get away for a while to clear his head. He liked Sean even if he hadn't interacted with him much but the fact alone that he had overcome his initial fear of werewolves and was now reaching out to Stiles for help, made him likable.
In some ways Sean reminded Derek of Isaac. His parents weren't as bad as Isaac's father had been but it was bad enough for Derek to feel protective over him. He had a soft spot for strays like Peter had put it, he knew that, and the way Stiles was there for his friend just made the urge to protect stronger. In that way Sean was pack.
On the other hand, however, was Sean a stranger.
Derek didn't really know him but Stiles trusted him and that was more than enough for Derek to trust him as well, to a degree. He couldn't shake off the uneasy feeling, though. Derek had trusted before, had let her lull him into believing that she loved him. He had let her in and she had burned down his family in return.
Derek knew that Sean wasn't like Kate. But feelings weren't logical.
When Derek came home after his run, Stiles and Sean were long gone. Derek showered and then set up his workplace to get some things done while Stiles was at school. He didn't know if Sean would come over again later or if he would have time with Stiles alone, either way, he wanted to get his work done so he had some free time later.
There was an email from Professor Rodriguez waiting for him.
Derek read it three times and had still no idea what to say to her offer. He would translate her book soon, he was in the middle of reading into the topic, and it was normal to stay in close contact with the author to check some facts or to clear something up Derek didn't understand. It was important for the translation.
What wasn't normal was to visit the author at her work place and have an internship to really understand what she was talking about. It was a great opportunity and Derek was tempted to accept on the spot but he wasn't sure if he should leave his pack this soon again. He had never been keen to travel around but lately he had the feeling that he was more away than he was actually at home.
He had a mate now. He knew that Stiles would take care of the pack while he was gone so Derek was able to leave for a while.
But he should talk to Stiles first anyway. If Stiles didn't want him to go, he wouldn't go.
Derek set the email aside for the moment and focused on his other work. He almost forgot lunch, Stiles would have a word with him if he didn't eat properly, they had been there before, so in the early afternoon he took a break but he ate his sandwich at the laptop while he read more about radio signals in space.
He totally forgot the time so he looked up in surprise when the front door opened and Stiles stepped in. He was alone for once. Derek didn't mind having Sean over, especially when the teen needed a safe place to hide from his parents, but it was nice to have Stiles for himself from time to time.
"How was school?" Derek asked.
"Same old." Stiles dropped his backpack in the corner and then took the chair next to Derek. He eyed the half-eaten sandwich, Derek had totally forgotten it, and made a disapproving noise in the back of his throat. Then Stiles shrugged and ate it himself.
"The chemistry test?" Derek prompted. Stiles was his mate but at the same time he was the high schooler Derek was responsible for which meant that he should ask about tests and grades and things like that.
Stiles made an amused noise around his mouthful of sandwich which could translate to an annoyed "please".
Derek hurried to save his work and close his laptop. By now Stiles had finished the sandwich and had put the plate in the dish washer. Derek wanted to ask about Sean, he hadn't meant to scare him earlier today, but he didn't know how to phrase the question without making it sound guilty. He meant it. He would protect his pack.
However, Stiles seemed to know what was on his mind.
"You didn't scare him off for good." He said. "Death threats are more or less what he expects from a big bad alpha like you. What still boggles him is that we count him as pack. And that you let me pet you." Stiles laughed and ruffled his hair. Derek growled at him but Stiles wasn't impressed.
"Who's a big bad alpha?" Stiles asked in that over cheerful voice while he gave him a few affectionate pats on the head. "You are."
Stiles yelped in surprise when Derek jumped out of his seat.
"I'll show you big and bad." He growled around his fangs and backed up Stiles against the fridge.
"I'm frightened." Stiles mocked him, not in the slightest intimidated by the alpha looming over him with glowing eyes and fangs out.
Derek braced his clawed hands on the fridge on both sides of Stiles' head and stepped even closer until he could slip a leg between Stiles' and pin him down with his hip.
Stiles rolled his hip against Derek's and then he leaned in with a smirk and licked along one of his canines. Derek closed his eyes with a groan.
Stiles nibbled along his bottom lip until Derek retracted his teeth so that they could kiss properly. Grinding their growing erections together Stiles moaned into his mouth and slipped his hands under Derek's shirt.
With his nose buried in the crook of Stiles' neck Derek breathed in the heavy scent of his arousal, making his head dizzy.
Stiles didn't stop kissing every inch of skin he could reach, adding a bit of teeth here and there. Derek groaned into his skin and sucked a hickey right on the claiming spot. Satisfied with the forming bruise, framed by the imprints of his teeth, Derek licked over it one more time.
"What do you want?" Derek asked between little kisses along Stiles' jaw line. "Want my hand on you? Or do you want me on my knees?"
Stiles' eyes rolled back and his head hit the fridge with a thud.
"I want …" He breathed out while Derek mouthed along his throat. "I want you in me."
Derek froze and the hands under his shirt stopped as well. They had been building up to this and if Sean hadn't been over so often lately they would have done it days ago but now that Stiles was actually asking for it, Derek wasn't sure.
"We don't have to." Stiles gave him an out. "But I'd like to. If you want to."
His hands had started moving again but now they weren't just frantically roaming over his back any longer, now it was a steady up and down, calm and reassuring.
Stiles looked him in the eye, waiting for an answer. His gaze was open and full of trust, his pupils blown with lust.
"Okay." Derek said and sealed the decision with a kiss. "Upstairs, my bed."
How they made it up the spiral staircase without falling and breaking some bones Derek didn't know but somehow they made it to his bedroom in one piece.
"We're wearing too many clothes." Stiles proclaimed, tugging at Derek's shirt.
A second later Derek had to catch him from face-planting when he stumbled around with his pants around his ankles and for a second Derek's mind flashed back to their drive home from Laura's and he was tempted to throw Stiles on the bed hobbled like this. But then Stiles got his feet out of his jeans with a proud grin and Derek got distracted by the lean lines of his body.
When they were finally naked, Stiles drew him into another kiss and then dragged him down with him on the bed.
"How do you want me?" He asked and Derek heard the light tremble in his voice. But Stiles was still smelling of arousal and his skin was flushed and there was a bead of precome on the head of his erect cock. So Derek just kissed the light worry away and urged him farther up the bed.
"Just lay down." Derek took a moment to put a pillow under Stiles hips and to get the lube. Then he just looked at Stiles stretched out and waiting for him.
"You're perfect." He crawled over him and brought their lips together.
"You're not so bad yourself." Stiles said with a grin. "But I swear I'm going to kill you if you don't do something. Like yesterday."
Derek just smirked. He took his time to map out Stiles' body with his hands and mouth and by the time his finger finally slipped in the crease of Stiles' butt his mate was panting and writhing under him.
"Derek." Stiles whined, the tight ring of muscles fluttering under the tip of Derek's finger.
"I got you." He promised and reached for the lube. He was probably driving Stiles insane with his thorough prep, working in one finger after the other, giving Stiles time to adjust to the feeling, but he didn't want to hurt his mate.
He couldn't help but think back to the night when he had claimed Stiles and he was determined to make it better for him now.
His own cock was aching and all he wanted to do was to pin Stiles down and just push in but he forced himself to go slow. One maddening inch after the other he pushed in and by the time he was fully seated, they both were covered in sweat and panting. Derek rested his forehead against Stiles', waiting for him to adjust to the stretch.
"Move." Stiles breathed out, blunt fingernails clawing at his back.
Derek started to move, slow at first but when Stiles met him with every thrust, he let instinct take over. Hot and tight, Stiles felt just perfect around him.
Before he knew it, he was fucking Stiles in earnest who was still shouting for more and harder. Even in bed Stiles didn't shut up and Derek rode on his shouts of "fuck" and "Derek".
Derek slipped one hand between them and it took only a few tugs at Stiles' rock hard cock for him to spill his release. Derek followed him a few thrusts later with an animalistic grunt and a flash of red eyes.
Stiles closed his arms around him and didn't seem to mind that Derek had just collapsed on top of him.
After a minute Derek took pity on his mate and rolled off but he was still too lazy to clean them up. Stiles snuggled closer and pillowed his head on Derek's shoulder and seemed to be content with just lying there for a little while longer, too.
It was still afternoon so they had to get up at some point, Stiles would insist on dinner, but for now Derek carded his fingers through Stiles' sweaty hair and just enjoyed the afterglow of a good orgasm.
Of course Stiles couldn't stay quiet for long.
"So, you went on a run this morning." He said, his fingers lazily painting patterns on Derek's chest. "What else did you do all day?"
"Work." Derek answered, there wasn't much to tell. But then he remembered the email. "Professor Rodriguez invited me to visit her so I can have a more in-depths understanding of her work."
"That sounds great." Stiles snuggled up closer to him. "For how long will you be gone?"
"Two weeks."
Stiles thought about that for a moment.
"Just so we're clear on this." He craned his neck to look at Derek. "Before you leave for South America for two weeks, I absolutely need your knot inside me at least once."
