The pack was franticly looking for information to break the curse put on Derek. While fighting a witch, she was about to hit Stiles with a spell but at the last moment, Derek pushed the human out of the way. The spell worked quickly, making Derek shift into his wolf form and immediately he attacked the witch killing her on the spot. When the pack got close to him, he growled protectively not letting anyone close, snapping his jaw at them. It was quickly determined that he was feral and there had to be a way to reverse the curse put on him. So the pack banded together to find anything. For Lydia and Stiles it was easy to look through book after book to find what they needed, but for the others not so much, getting confused at some of the books written in different languages.
Eventually, something was found, but it wasn't good news. The only way Derek's curse could be broken was with a virgin sacrifice. The pack discussed what they were going to do, they knew they needed Derek back in human form but killing a person just to do that was insane, there had to be another way. Something that didn't make them murderers.
Stiles sat alone, the pack arguing in the background as he reread the passage of reversing the curse. "A virgin's sacrifice..." He read out loud. Maybe there was another way, something less literal.
Hearing the pack still yelling at each other, he made a very dumb decision went to see Derek. They had locked up the feral wolf in his bedroom until they could figure out what to do with him. Opening the door, Stiles saw the black wolf on the bed, head high as he growled at the intruder.
"Hey, Derek," Stiles said, his voice a bit shaky. "So we figured out what kind of spell that witch used. And we also found a way to reverse it." The wolf got up, his growl even louder than before, more threatening. Stiles gulped audibly, terrified that he was doing something completely foolish that could get him killed. "It said something about a virgin's sacrifice, and I was thinking, well, I'm a virgin." He quickly stripped off his plaid shirt, the wolf stopped growling. Stiles sighed in relief. "And the pack thinks it means we have to kill someone to get you human again," he took off his t-shirt and tossed it to the side. "But I don't think so. At least I hope I'm right and won't get killed in the process."
The wolf tilted his head as the human unbuckled his pants and let them fall. The scent of fear was filling the small room, but there was an underlying scent of something else. Excitement? Joy? No, arousal. The wolf licked his chops, as his cock started to grow, poking out of the sheath. Stiles looked at the cock get bigger and got hard himself, the head hitting close to the fly of his boxers. Jumping off the bed, the wolf stalked him prey, his hard red cock bouncing as he made his way closer to the shaking human. Stiles made a small noise as the wolf bit into his underwear and pulled him away from the door and then when the human was far enough away, ripped the boxers right off his body. Stiles would've said something about him ruining his superhero boxers, but the long and thick tongue wrapped around his dick making him shutter. The wolf sniffed around Stiles's naked body, every so often giving him a lick just to make the human make a noise in shock. By the time the wolf was at his ass, both of their dicks were dripping, excited to see where it would lead. With a strong stripe of the tongue up his ass crack Stiles silently moaned. The wolf nipped and pushed him with his snout to the bed. Lifting his leg to get on, Derek continued his licking, focusing on Stiles's hole. The human fell forward onto the bed, leaving his leg up to let the wolf have better access to his hole. He moaned into the mattress as he was rimmed, he didn't realize how pleasurable his ass could be, Stiles was going to do some further experiments on that when he got home. After a bit of more licking, the wolf bit his ass cheek and growled, turning a bit to see what was the matter, he could tell that the wolf wanted him to move over. Giving another bite made Stiles move up, staying on all fours, lowering his chest so his ass was in the air. The wolf continued to lick the human's exposed hole, Stiles dripping precum onto the mattress and pulling a nearby pillow to himself so he could keep quiet. He thought he was going to cum just from that but then the licking stopped. Looking over his shoulder, he watched as the black wolf jumped onto his back and scooted forward, the wet tip of the cock hitting his ass cheek. Stiles moved his ass, and then he realized how incredibly stupid that was, Stiles was a virgin and seeing how big Derek's wolf cock was he couldn't possibly handle something like that. But his moving proved just the thing to do as the wolf was about to hit his hole and pushed in. It thankfully went in slow, but it was a constant push and stretched it more than Stiles thought possible. He shoved his face in the pillow and let out a cry, the wolf whined over him as he pulled out, not from pain but because Stiles was.
"Don't," Stiles grunted. "It'll get better. But don't stop."
Pushing back in, the wolf moving slowly like the wolf was scared to hurt the human. Stiles relaxed, or at least tried to, but he couldn't figure out how he was supposed to while getting fucked for the first time by a big cock. But then the wolf hit something that made Stiles moan out and arch his back, feeling incredible pleasure. The wolf purred in his own pleasure at making the human moan, he started pumping faster, hitting that spot every so often. The feeling of the wolf's fur was becoming a comfort, something Stiles was not looking forward to examining, but for some strange reason it felt like the wolf wasn't as furry. The fucking became more rhythmic and even the cock in him felt different. An arm wrapped around Stiles's chest, lifting him up a bit, while another slid across his stomach, moving downwards to his throbbing dick.
"Der?" Stiles gasped.
"You feel so good," Derek's voice was rough, his speech a little slurred because he his fangs. A hand wrapped itself around Stiles's dick, stroking him. "Cum for me, baby."
The base of Derek's cock expanded, the last traces of him being a wolf was taking place. Stiles felt so good, he didn't notice at first, only felling the knot a bit too late. He shouted out as he was knotted, cum shooting out all over the bed.
The wolves stopped, hearing the cry, for the first time realizing that Stiles wasn't there. Scott rushed upstairs to Derek's bedroom, about to give his friend a piece of his mind. But as he opened the door, he was shocked to see not only see, Derek back in his human form, but Stiles lying right next to him, the pair covered with blankets. Taking a breath he knew exactly what had happened and wished he didn't.
"Is there a reason you barged in here, Scott?" Derek growled.
"Um...no. Well, I was just trying to find Stiles."
Derek stroked the sleeping boys cheek. "He's been here. I heard you all were thinking about killing someone to cure me. I guess you don't have to do that anymore."
"No... I guess not..."
"Well, when Stiles wakes up, I'm going to show him how much I appreciate him sacrificing himself. I'd advise everyone leave before they hear things they don't want to."
"Yeah... I'll let everyone know. And um... it's good to have you back." Scott quickly closed the door and numbly went back downstairs.
"What happened?" Issac asked.
"Are they ok?" Lydia wanted to know.
"Yeah... They're fine...um..."
The wolves sniffed the air a bit.
"Did Stilinski fuck the wolf?" Jackson shouted.
"I don't want to know. All I know is that Derek is human again and he's going to thank Stiles when he wakes up."
"Get it, alpha," Erica shouted, knowing Derek heard that.
Boyd picked her up and carried her out the door, the rest of the pack leaving as well. Scott closed the door, not knowing how he was ever going to face his best friend ever again.
