Chapter 21

"Derek?" Stiles whimpered from his position. The werewolf did not respond with words, only a slight growl. Stiles felt his own heart racing quickly. "Derek?" he tried again, trying to get up from the spot.

Derek's hands started to roam across Stiles' torso. His lower half rubbed experimentally against Stiles' ass before shoving forward. Stiles felt himself move forward with the thrust. His hands reached out to the edge of the desk to brace himself. The morning's bathroom experience flashed into his mind as the werewolf thrusted several more times.

Stiles knew he should be worried, but Derek felt so good. The man's hands had worked their way underneath Stiles shirt and slowly lifted it. Stiles tried to help, but Derek got impatient. With a growl, Derek ripped Stiles' shirt off of the boy's body.

Stiles moaned as Derek's hands moved over the boy's body. Derek cupped Stiles' crotch and whispered in Stiles' ear, "Mine." The boy nodded repeatedly and pushed against the hand.

"Yours."

Derek popped open the button on the boy's pants and unzipped them. His tongue traveled down the boy's neck and he bit the boy's shoulder. With one tug, Stiles' pants fell down to the floor. Derek repeated the action with his own pants. His thrusts became harder as the thin silky boxers were the only barrier between Stiles' body and his.

Stiles tried to match Derek's rhythm but was lost. He'd never done this before in his life. Sure there was a dry humping situation at camp one year, however, it did not compare to the power of the man above him. He groaned as Derek's fingers grabbed his hips and forced him further. He could feel the bruises already starting to form.

The feel of Derek's cock against his ass nearly made him spill himself. "Derek," he whispered. He reached backwards and grabbed a fist full of Derek's dark locks. The werewolf moaned in approval as the boy pulled the hair closer to him. Derek sucked a red mark onto the back of Stiles' neck and licked it.

Stiles kicked off his shoes and pants. He wanted to feel more of Derek. He wanted to be able to touch him and kiss him. With his face in the desk, he couldn't do that. "Derek, please," he whispered, losing his mind as Derek's thrusting became hurried and rough. The werewolf's breath was hot on his neck. The usually quiet werewolf was making little grunting noises.

Stiles couldn't help it. He wanted more from Derek. He wanted the werewolf inside of him. He wanted to kiss him. But Derek seemed determined not to let that happen. "Let me kiss you," Stiles asked.

Derek paused and within a second, Stiles was on his back, his legs spread. Derek leaned forward and kissed the boy passionately. His tongue licked Stiles' lips before delving into the boy's mouth. Stiles suppressed a groan of satisfaction.

The werewolf thrusted forward, their cocks rubbing against one another under their boxers. Derek reached forward and removed the rest of Stiles' new shirt. His own shirt had disappeared. Stiles' trembling fingers reached forward and caressed the werewolf's chest. For too long he had wanted to touch the man. For too long had he wanted to be with him.

Stiles groaned as Derek's fingers reached into the boy's boxers. His lips kissed every inch of Stiles' chest as the fingers wrapped around the boy. The thrusting increased in speed. Stiles was overwhelmed with the sensations. His hand returned to Derek's hair and yanked the man's face up. He was shocked to see the red eyes and fanged out teeth. Stiles felt his cock twitch as he pulled the wolfed-out man's face to his for a kiss.

Stiles boldly shoved his tongue into Derek's mouth, trying to match Derek's thrusting. The werewolf's tongue battled his own. Stiles felt something sharp cut into his tongue. The metallic tang of blood quickly dissipated as Derek's hand twisted a bit around the boy's cock.

Derek swallowed Stiles' moan of completion as the boy came in his boxers. Derek growled viciously as the man thrusted one final time. Stiles could feel the wet warmth on his own boxers from both of them.

The werewolf removed his mouth from the boy's and rested his forehead on the boy's shoulder. Both couldn't say or think as they tried to still their hearts. Their breathing matched one another.

After a few moments, Stiles let out a small laugh. Derek's face lifted in fear as he took in Stiles' expression.

"Taking it slow?" the boy teased him. Derek dropped his head down to the boy's chest. A muffled apology was barely audible.

"Can we do that again?"

Stiles felt the werewolf's chuckle against his chest. He stroked Derek's hair as the werewolf relaxed against him. He could live like this for the rest of his life. He could wake up to Derek kissing him and some sexy-times. He could simply lay there and stroke the werewolf's hair. His werewolf's hair. The growling, the teeth and the red eyes were a bonus. His mind started to wander to what Scott did during sex, and he nearly jumped.

Derek's face lifted again in confusion.

"Scott just popped into my mind."

"Just what a boyfriend wants to hear right after this," Derek replied.

Stiles laughed and hit the werewolf lightly in the arm. "Do you guys always wolf out like that during sex? Is it just an Alpha thing?"

Derek looked pensive for a moment before responding, "It's my first time doing that."

Stiles felt himself blushing as he thought about that. Derek looked so innocently confused about the situation, and Stiles was 100% clueless what to say. He pulled the werewolf towards him and kissed him. "I could get used to this."

Derek smiled and kissed him back.

After waiting for what seemed like forever, Derek came back to the office with new boxers and shirts for the two of them. "The others are waiting in the food court for us."

"Food! I am famished," Stiles said dramatically as he pulled his used boxers off of his body. He turned slightly away so Derek couldn't see the mess the two had made. He used the boxers to clean himself up a bit and then put on the new pair. "Really?" he asked as he turned towards Derek. "You got me Wonder Woman boxers?"

Derek smirked as he put buttoned up his own pants. Derek was a quick dresser, and Stiles was disappointed to see that body covered up.

"You like comics, don't you?" Derek teased as he pulled the boy into his arms for a kiss. He pulled back slowly and looked Stiles in the eyes. "I didn't hurt you did I?" he asked as his fingers caressed the red marks on Stiles body.

Stiles shrugged and smirked. "My first sex injuries."

"Injuries?"

Stiles glanced at the worried werewolf and pointed to his hips. "You have quite a grip on you."

Derek hung his head slightly in shame. His fingers traced the marks carefully. "I'm so sorry. This is why we should have waited. I have to control myself better in the future."

The boy finished dressing as he considered what his boyfriend had said. "Why did you lose control?"

Derek sat on the chair in the room and shrugged slightly. "I don't know what came over me. That girl had her hands on you, and I wanted to rip out her throat." He paused for a moment and put his head in his hands. "I've never wanted to do that to a random person before."

Stiles nodded as he sat on his boyfriend's lap. He pulled Derek's hands down from his face and looked the man in the eyes. "You weren't going to hurt her. You are not that type of person. You are incredible." Stiles kissed Derek on the forehead. "You were just protecting me."

Derek sighed and wrapped his arms around Stiles. "I was livid when I saw her grab you. I had to mark you, make sure she knew not to touch you again."

Stiles nodded and set his head on Derek's shoulder. "So you took me to this room to mark your territory."

The awkward silence lasted all of three minutes before Stiles' phone began to ring. Neither of them wanted to move from their embrace to answer it. Stiles played with the zipper on Derek's jacket as he thought about their situation. In a couple of months, Stiles would be gone. There'd be no more sexy-times in random offices. There'd be no more cuddles in the morning and no more kisses.

Stiles rubbed his face against Derek's neck. After what they did, Stiles should be exhausted and asleep. Any kind of exertion of energy, especially that much, should have knocked him out. Instead it seemed to do the opposite. Stiles was processing this as both cell phones went off.

Derek groaned and readjusted Stiles so that he could roll the chair near the desk. He picked up his own cell phone and answered it. Stiles cuddled further into Derek's chest. He caught Derek's free hand and held it.

The werewolf only grunted responses to whomever was on the other line. His eyes glanced down at Stiles a couple of times, but he didn't say anything. After hanging up, Derek pulled Stiles' face up for a kiss. "You're not my territory."

Stiles smiled softly at that. "I wouldn't mind you, um, marking your territory in the future."

Derek laughed as he kissed the boy's forehead. "We have to go. That was Isaac. Lydia has called a meeting at the vet's office. Apparently she has a solution to something. The others are leaving the food court and heading that way now."

Stiles' heart skipped a beat, "What something?"

Derek pulled Stiles closer to him and shook his head. "She knows and I think we should hear her out, if you want."

Leave their little love bubble to go back to reality? Stiles shook his head as he thought about it. If anyone could find a cure, it'd be Lydia. He sighed and played with Derek's zipper again. "Fine. Let's go see what the banshee has cooked up for us. Speaking of food, let's get food first!"
