Derek was pissed.
No.
He wws beyond pissed.
When he came back to the pack house with Isaac, the poor boy still anxious about being around so many wolves, he saw his beloved mate standing at the entrance with a serious face. This was the first flag, he knew something bad had happened, he was worried when he reached out to Stiles and felt it being actively blocked, cancelled, not desired. It hurt Derek but when he saw Stiles' tears, he couldn't help but be much more worried about what had happened. So he came forward and hugged his mate, and then the bond snapped back in place and he could see, feel, and know what made Stiles this mad. Anger, fury, sadness, shame, and a lot of other emotions clashed together as memories were shown to him, he saw how Deaton was a Darach, he saw how his mate kept it from him, he could understand the reasoning behind it since he was seeing the point of view from his mate... He wanted the man to suffer and he knew Derek would make it quick, so quick it would've been mercy.
Then why was he angry? Because his mate was blaming himself, he was having a terrible internal crises because he thought Derek would be beyond pissed at him- and although he is pissed at his Stiles, is not because he hid this from him, but because he thought he would he mad that he hid it from him, like he didn't know Derek wouldn't- Wait, he didn't know. They don't know much about each other, this hit Derek like a brick, they've taken this so quick there was not a lot of time to know each other intimately, so he decided to do the only logical thing. "We're going on a date." When these words left his lips, Stiles' stunned crying face made Derek want to laugh a little, but Stiles only tilted his head like a confused puppy- he must do this as well, because he now knows why Stiles squeals when he does it- he kissed his Stiles' temple with a smile and sent all his thoughts, emotions, and plans to Stiles who blushed. "I... Okay." The whisper was so adorable he couldn't help but kiss him, licking his tears away with a smile in his lips as he mentally told Stiles: "I love you, you know that, right? You don't need to hide things from me. You could've explained, i understand why you didn't, but it still hurts a little not being truste enough to be told... You'll have to do so much make up."
Stiles nodded, not even daring to speak with Derek mentally, fearing his voice would crack even mentally, Derek bit his lips and cheered him on: "Go put on some nice clothes, we'll be going now." Stiles smiled weakly and walked upstairs, he would obviously wear Derek's clothes as Derek sometimes would wear some of his clothes as well, he just took a plain black shirt alongside one of his leather jackets, they were big on him (Well, all of Derek's clothes really), but he didn't care. He liked it and Derek liked it, so why should he care about anything else? About the bottom he was already weary some nice tight pants that Derek liked, he said it made his ass look extra juicy, so of course he began wear only these to tease Derek. Everything they did was likely foreplay outside of the bedroom, Derek sniffing him, Stiles' oral fixation always sucking his fingers, biting things, licking things that got too close to his mouth, Derek's husky, deep voice when when he whispered things to him, Stiles' thin cute fingers that liked to touch things, Derek's growls whenever someone they didn't know began to get too touchy with Stiles, The "accidents" that happened whenever Stiles saw someone looking at Derek with lust, like tripping, sneezing too hard they fart, shitting themselves, breaking a bone, having internal bleeding, losing an organ, you know, the usual.
They were the little things that made Derek wonder how Stiles could get rid of a corpse so fast and why was it so hot- I mean, why he loved whenever Stiles would look at him, smile at his direction, shift closer to him, the little laugh that Stiles had and little noises he made unconsciously that Derek was sure even Stiles himself didn't notice how both resembled foxes, how adorable his eyes would narrow when he smelled the scent of dust and or ash, how his body would flinch when he saw blood but he wouldn't hesitate to spill it when it was rrlated to Derek... Such a strong mate he had, so he was going to make him pay for not telling him, in a very sexy, wild way. That's why they are going on a picknick and later going to his wood shack on the middle of the forest, where he will enter Rut.
A period of time that every Werewolf has to go through, it normally happens on their 18th birthday and it is a period of time in which a Werewolf is ready to mate and have puppies, and that period is the most fertile one for a werewolf and sex will always result in puppies, unless its a same sex couple, so there is only pleasure for about a whole week. If the human can keep up, which he is sure Stiles will keep up with him, his Mate has always been keeping up with him whenever they have sex and the stamina he showed was impressive too. He sent the images of his first Rut to Stiled while telling him in detail what would happen, how he would fuck him in several different positions, how he would just wreck him so bad he wouldn't be able to walk for a whole week and feel his dick deep inside him even three days after.
And to say Stiles was aroused was an understatement.
The moment he saw the smaller man come downstairs smelling like him and wearing his clothes, he almost fucked him right then and there, he was very aware they smelled of deep lust and love, but he didn't care because when he looked into Stiles' white and blue eyes, they were in their own world. Nothing and no one else mattered as their eyes locked into each other's, it was magical and the wolves around them couldn't help but shy away, as if they were invading something private. "Let's go?" Derek offered his hand to Stiles, who eagerly took it with a shy smile to his beautiful red lips, making Derek swallow dry as he imagined how roughed up those were lips going to get after he was done with them... Such sinful thoughts followed him as hs took Stiles by the waist into his camaro, Isaac, meanwhile, stood traumatized in the corner.
Meanwhile, deep in the "dungeons" of the Hale's Pack House, or the basement, Peter's just being dramatic by calling it "dungeons"... This isn't gloomy enough to be considered a dungeon anyway!
Back to the description, in the deepest part of the Hale's Pack House was a man, his name was Alan Deaton, he managed to fool the Alpha Thalia Hale for years by being her Emissary. Hid plan? Easy, as a Darach, he wanted power of course, so he would tie himself to the Nemeaton, the beautiful tree that was in the middle of the Preserve. However, no matter which method he could think of, it wouldn't be the PERFECT one, so he had to think long term. He then analyzed what all rituals had in common, a sacrifice, and what better sacrifice than a pure soul? And only the purest of souls can become a True Alpha, so he began his tests, he manipulated several young men and women, making them into Werewolves and secretly presented himself as a "powerful friendly druid" that was there to help them, he would then hide their scent and presence from the supernatural world, he would also trll them to not tell anyone, not evem their family, because it can get them killed.
When they failed to become a True Alpha, he sacrificed them, after all, they were still Werewolves and Werewolves can be great sacrifices to gather power, and he sacrificed a lot of them to get the power he needed to be truly undefeatable, undying, unapologetic destructive and chaotically savage. Then, when the pure boy Scott McCall successfully became a True Alpha, Deaton almost had an orgasm just by thinking the amount of power he could get from not only fusing himself completely to the Nemeaton, but completely becoming it, he would be so powerful... The boy, however, must be kept pure and virgin, so Deaton placed a powerful [Compulsion] spell to make sure he would never kill anyone, nor would he have sex with anyone, then he kept manipulating the boy to make himself a pack outaide of Beacon Hills because here was "too dangerous", and like a little obedient puppy, he went out of town, to the neighbor little town of Blue Horizons, that was somehow smaller than Beacon Hills for some reason.
An Alpha with a pack is stronger, an True Alpha with a strong pack is even better.
Now, Deaton was strapped to the wall with Shackles that prevented him from reaching out to touch anything, his mouth also had a gag that prevented him from speaking anything.
"If you were hotter, i would've think this as very kinky, but sadly you are an ugly bitch." Peter commented while his hands moved through the instruments of torture, Thalia was pissed at Alan, well, Alan just thought it was funny how an outsider was able to figure everything out while in the 20 years he is Thalia's Emissary, she never even suspected him... "Now, i think we can start. Thalia didn't sent me here to get answers from you, so i guess I'll just have my fun with you, if you want to add something just scream really loud- Oh, you can't. I forgot. Gagged..." Peter shaked his head as hjs finger stopped on something that made Alanis eyes widen. "Oh, my little darling... Wrecker." A vicious grin was on Peter's face as he looked at the thin but sharp looking jagged blade in his hand, the blade was designed to easily enter the skin and muscle, but leave it hardly.
And it can also be used on barbecues, so that's a plus.
"Now... Let's start."
Derek kicked open the wooden door of his isolated shack in the woods, it wasn't a shack per say, it was the size of a middle house, with four rooms, one kitchen, one bathroom, and one garage. As well as the attic too, oh, and the basement... Stiles smiled, this was their pack house. Derek's and his room was the room with all the bookshelves that had some of the books he had inside his personal storing dimension, he loved looking at them, but right now he had his focus on the glowing red eyes of his Alpha who was slowly walking towards him, Stiles had an idea and smiled, he quickly approached Derek and kissed him deeply, when Derek was stunned for a second Stiles slipped pass him and ran down the stairs. He heard Derek's low growl as he laughed and dodged to the right, a large hand passed by and he perfectly avoudrd getting caught by the wolf, they ran around the house, playing this game of tag where Derek's wolf was hunting his prey down, and it only stopped when they entered another room and Stiles was cornered by the big bad wolf, who had a wolfish (heh) grin.
"Caught you." Growling, Derek began to scent mark Stiles with his cheek, rubbing his stubble beard against Stiles' neck, making him shiver and whimper as Derek pushed him down the bed, this was one of the 3 guest rooms of the house, and Derek was pressing him down to the bed with a hungry smirk as he bit down where his mark was on Stiles' body. "Argh-" Stiles moandd surprised, almost sounding like a gurgle, but Derek growled there with his mouth anf throat close to Stiles' throat, vibrating alongside the beating of his pounding heart. Then Derek smelled it, he raised an eyebrow as Stiles' blushed deeply at him. No, he did not cum from being bitten, no, something else was happening with him. "I... This never happened before."
"I didn't know you could get slick." That's what's happening to Stiles, he was getting slick, just like a woman's vagina gets ""wet"", Stiles' asshole was getting wet as well. This normally happens with females only, Derek went through his head, thinking about why would Stiles get slick and then it clicked. The little ways Stiles acted as a fox was instinctual, as if he was one, but Stiles is not a Kitsune, he would smell it. "Stiles?" Derek's confusion but deep arousal awoke him from hjs confusion as he chuckled nervously: "Ergh... Damn, you know like, when a Spark becomes Ablaze and we die and are rebon from the ashes? Our bodies are made out of the energy of our bodies, working just like our original bodies, built like our original bodies, but it isn't our original bodies... They are perfect replicas that can adapt to things, this change happens magically."
"Like when you shift?"
"Like that, my body melts and reconstructs, becoming my shift. And this also happens when my body needs something, or wants something, or is preparing for something."
"So you mean...?"
"My body wants you so bad I'm getting wet for you. I mean, my body is getting ready to get your dick for a whole week straight, and maybe get pregnant, maybe."
"Stiles, you can't get pregnant."
"Wanna bet?"
There was a few seconds silence before Derek's eyes flashed red in arousal as he began his week long mating.
