Some violence. Borderline Coercion. Approach with caution.

While Stiles tried to recover from the ambush, he felt a hand trailing down his stomach and easing itself under the waistband of his shorts. Stiles opened his mouth in sheer terror. Derek seized the opportunity and forced his tongue inside kissing him with an intensity that took the breath right out of him.

The total lack of experience made Stiles freeze up, and he was totally unable to reciprocate the kiss. Another issue was that Derek's hand was wrapped tightly around Stiles' cock, making it very hard to stay focused on anything.

Derek pulled back for a second, giving Stiles a chance to take a breath. "I came for this." Derek smirked and moved in for another kiss. Stiles put his hand on Derek's chest and held him back. "What? Why? What are you talking about? This is..." He sighed and tried to meet Derek's eyes.

Derek moved to lie next to Stiles. He still had his hand inside Stiles' shorts holding on to his cock and caressing the head gently with his thumb. "I have been thinking about it for weeks. Falling off the roof was a blessing in disguise. I might not have ever come." He gave Stiles a quick kiss on the cheek. "I can't promise not to hurt you."

Stiles hitched his breath and widened his eyes. "No! What? Wait! You can't just force yourself on me. You know what that is called?" He tried to keep his voice steady, but it wasn't easy. Derek scoffed. "I wouldn't dream of forcing you to do anything you don't want." He gave Stiles' dick a quick tug making a soft moan slip out of Stiles' mouth. "But you want this too. You've wanted it for a while." Another quick tug came followed by a trail of kisses down Stiles' chest.

Stiles' grabbed onto Derek's hair and pulled his head up. "I can't... I... how can you say that?" He knew it was true. It had been hard to admit, but Derek was spot on. It was still puzzling how he could know this.

"I could smell it." Derek let go of Stiles' cock and started to pull his shorts down. Without thinking Stiles lifted his butt to help out. When they were around his knees Stiles just kicked them off. Derek was still wrapped in the sheet but now he started to wiggle himself out of it. "I could hear your heart beat and even if you smelt like fear I could still sense the lust you emitted."

Derek was now untangled from the sheet, and Stiles wanted to look at him in all his naked glory, but he didn't dare to move. Actually, he couldn't move even if he wanted to. He felt almost paralyzed. Derek grabbed his hand and pulled it against his own crotch. "Come on. You have fantasized about this, haven't you? I have."

Touching Derek's dick was almost like an out-of-body-experience. Stiles kept his eyes closed, but he could see himself in his mind. Trembling fingers slowly crawling towards the shaft. Derek was guiding his hand and when it reached it's goal, Derek drew his breath quickly and let out a groan.

Stiles just stroke it gently letting his thumb ever so often touch the head. Derek didn't push him to do anything else, and Stiles was happy about that. He wouldn't have known what to do anyway. Derek was not so shy. His hands and lips was all over the parts of Stiles' body that he could reach from his position.

Never in his life had Stiles' been this aroused. It felt like he could cum at any time without having to put in any effort. As Derek moved his finger between his legs and caressed the hole back there, Stiles was gasping for air and felt his balls tighten. He was so close that it was ridiculous.

Suddenly Derek rolled over a little and reached for something on the floor. He pulled up his ruined leather jacket and sifted through the pockets soon revealing a small bottle. Stiles knew exactly what it was and started to shake uncontrollably. Derek rolled back and cupped his cheeks. "Relax. Everything will be fine, just relax."

Derek squirted some lube on his fingers and then he tucked the bottle under the pillow. While staring into Stiles' eyes, he moved his hand down Stiles' body. He stroked his cock gently with his palm making it twitch. Stiles wanted to touch himself, but he knew that he'd probably cum on the first tug. Anyway, his arms felt like lead so moving them was out of the question. Derek's hand continued on it's path and when he rubbed some of the lube onto the puckered hole, Stiles held his breath. Derek's lips on his chest distracted him somewhat, and before he knew it, he could feel a finger up his ass. It didn't hurt. Stiles got only enough time to get surprised by that fact when the finger moved and made his world shatter into pieces.

He felt his own cum hit his stomach, and got utterly embarrassed by it. He would have wanted to hold back. He felt like a twelve year old waking up from a wet dream. Derek kissed his cheek and gave him a crooked smile. "It's okay."

There was a gentleness in his voice that made tears pile up in Stiles' eyes. Derek really meant it. It was okay. Stiles managed to lift his hand off the mattress and stroke Derek's arm. "I have never... I'm..." The words got stuck in his throat when Derek moved in for a kiss. He put a hand under Stiles' neck, and lifted his head off the pillow; deepening the kiss in the process. Stiles went with it, and this time, he managed to reciprocate. His lack of experience bothered him for a second, but he grabbed on to Derek's shoulders and tried to let go of the embarrassment and awkwardness of the situation.

Without warning, Derek withdrew his arm, causing Stiles to fall back onto his pillow. He cocked his head and squinted. "Turn over." The gentle voice was gone and the words came as a raspy whisper. Again, Stiles noticed a little flash of red in Derek's eyes, and he worried for a second that the guy would turn and rip him to shreds.

Derek leaned forward and let his lips brush Stiles' neck. "He'll bite me. Tomorrow I'll wake up being a werewolf... or dead." The thoughts floated around in Stiles brains as a nibble on his earlobe made shivers go down his spine. "Turn over." Stiles could feel Derek's breath on his ear. Even fearing for his life, stupidity took over once more. "What if I don't want to? What if I'm fine like this?"

Derek's head was still tucked into the crook of his neck so Stiles couldn't see his facial expression. He startled when he heard the guy chuckle into his ear. "Stiles, Stiles. Don't be silly. You know you want it." He lifted his head and gave Stiles' shoulder a push. "Come on."

Stiles wondered what would happen if he actually got out of bed and refused to do as he was told; not that he wanted to do that. Stiles was again so hard that it hurt. Derek's intimidating demand and the fear Stiles experienced from it was extremely arousing. But then again, it was that other issue. Having a finger up his ass probably didn't qualify as giving up his virginity. What Derek was preparing for definitely was.

A slap on his ass made him lose his train of thoughts. He looked up with a frown and stared into Derek's eyes. "You hit me? That was not necessary. Do it again." Derek looked just as surprised as Stiles was when the words slipped out. "I mean..." Slowly Stiles turned over to lie on his stomach. He didn't know what to say. "Don't hurt me." The words came out on their own.

Derek let a finger trail down Stiles' spine. "I can't promise that. Sorry." A slap and an instant pain on his butt-cheek made Stiles jump. "I see. So your promises aren't worth shit." He braced himself for another slap but it didn't come. Instead Derek kneaded the flesh on his butt as he moved to sit between Stiles' legs. "I can promise you that it will be less painful if you shut up."

For a few minutes Stiles lied still and tried to stay calm and collected. Derek's hands felt good on his skin. Every so often, a finger traced the crack making Stiles shiver a little. It was all good and sweet; way too sweet in Stiles' opinion. "Hey! Did you fall asleep back there? I thought..." He got cut off by a slap so hard that he had to arch his back and let out a cry of pain. "Better?" He could hear that Derek was smirking. It was in his voice. Stiles drew his breath. "Yeah. I guess."

He got another little slap. It was almost like a caress, but the words that followed it made it more demanding. "On your knees, bitch!" Derek's voice was raspy, and Stiles hesitated for a second. "Bitch? What a nerve." He tried to turn and look at Derek, but Derek had now put his hands on Stiles' hips and pulled him up on his knees. "Yeah. You're my bitch tonight. And it's gonna hurt but it's gonna feel so good."

Derek reached his hand under the pillow and grabbed the bottle of lube. "If you want me to be gentle you shut up and don't complain." Seconds later Stiles had Derek's finger on his asshole, smearing lube around it. He could almost not keep himself up, but Derek's hand firmly placed on the front of his thigh helped a lot.

When he again felt the finger up his ass, Stiles had to bite into the pillow. He wanted to push back to get it further in, but he didn't dare to interfere. It didn't take long before he felt Derek's knuckles against the skin anyway. Slowly, Derek moved that finger in and out before he, without warning, added another. This time, a whimper escaped Stiles throat and he stuffed the corner of the pillow into his mouth to prevent a cry from coming out.

Derek took his time and twisted his fingers obviously to stretch the hole. Stiles couldn't take it any longer. He pushed back until he again could feel Derek's knuckles against the skin. "Hm, not so shy anymore?" Derek let out a growl that made Stiles tense up for a second. It sounded like a dog – or a wolf – and it scared him. Derek moved his hand from Stiles' thigh to stroke his back. "Relax. You're doing fine."

The sound of more lube being squirted out made Stiles tense up again. He was in pain but Derek was right, it also felt so good. Suddenly the stretch of the muscle became almost unbearable, and Stiles guessed that he now had three fingers up his ass. Trying to breathe with half a pillow down his throat wasn't easy, but he was pretty sure he'd wake up the whole neighborhood if he removed it.

Without any warning, Derek pulled his fingers out and leaned over letting both his hands run over Stiles' back. "You okay?" He whispered as the hands reached the butt-cheeks. Stiles could only nod, but he wasn't quite sure if he was okay. Seconds later he felt the head of Derek's cock on his hole. He did his best to relax knowing it was probably the absolute best thing to do.

He felt the pressure as Derek pushed forward, and suddenly the stretch almost made him pass out. Tears were piling up in his eyes, and even the pillow couldn't muffle the whimper that escaped. The funny thing was that the pleasure that came along with this excruciating pain gave him a high that numbed it somewhat.

Derek had promised to be gentle and he was. He moved a little back and forth, getting further in with every thrust. Stiles had to tend to his own throbbing cock before he went crazy and managed to get his hand out from under the pillow. The moment he wrapped his hand around his own member, Derek's hand covered his and together they jerked Stiles off with slow, steady moves.

Shortly before Stiles reached his climax, Derek's hand disappeared as he started to increase the pace of his thrusts. Now with his hands on Stiles' hips, he wasn't so gentle anymore; but Stiles was now so fucked out that it didn't matter. He cummed and had to get the pillow out of his mouth so he wouldn't choke on it. To avoid screaming, he bit his lip so hard he could taste blood. Suddenly, Derek slowed down again and with a howl, he released his load up Stiles' ass and dug his nails – or was it claws – into the flesh of his hips.

The moment Derek loosened the grip, Stiles fell forward. His ass felt like a crater; a sore, throbbing crater. Derek moved to lie down beside him stroking his back. Stiles didn't want to face him. He turned his head towards the other side of the bed and practically gasped for air. Derek kept caressing his back; it felt so good. Stiles could easily fall asleep like this, but he knew he had to get up and clean up before his dad came home.

"I think maybe your clothes are dry now," he said with a raspy voice. Derek's hand stopped moving on his back. "Oh, okay. You want me to go? Okay." He could feel Derek get out of bed and decided to follow his example. "I need to fix this." He pointed to the bed, and startled a little when he saw what a mess they'd made. The still damp sheet was almost all the way off. The pillow had bloodstains from Stiles' lip, and there were several bloodstains on the mattress. Stiles looked at his hips. On each side he had four small scars. They were deeper than a regular nail could have caused. Blood was still trickling out from a couple of them. Derek followed Stiles' line of view. "Oh. Sorry about that." He cocked his head and sneered. "I've marked you. You are my bitch now."

Stiles would have replied but he knew he needed to get in the shower. "I need to..." He pointed to the door and practically ran out. "What a nerve on that wolf." He thought as he tried to hit his asshole with the spray from the shower-head. "His bitch. What is he thinking? Rude and obnoxious that's what he is."

The fact was that Stiles felt surprisingly comfortable with the term. He looked at the scars and let a finger run over them. They didn't hurt that much but he knew he would have a constant reminder of this night for several days until they healed somewhat.

When he was done, he wrapped a towel around his waist and went to the laundry room to get the clothes. Back in the room, Derek was sitting on the bed. He'd changed the sheet and the pillowcase. The blanket was hanging over a chair. "It was still wet. Not so much but I figured..." Derek threw his hands out and shrugged. "Can I use the shower?"

While Derek was in the bathroom, Stiles went and got a spare blanket from his father's room. His father would probably ask why, but it could easily be explained. Showering with his clothes on and dive into bed without changing was not what he was going to say anyway. An accident with a glass of water was more believable.

Stiles lied down and waited for Derek to come back. He didn't know what to say to him. He didn't know if there was anything to say. He was definitely not a virgin anymore, and he wasn't sure how he felt about that; if Derek had come here to get his way with him and then move on it was a little disturbing.

Derek came back and sifted through the pile of clothes. He picked up his boxers and put them on before he pulled the t-shirt over his head. As he reached for the jeans, he turned towards the bed. "When is your dad coming home?" He lifted a brow and stared at Stiles. Stiles could feel a little flutter in his stomach. "In about three hours. He'll knock to wake me up but he won't come in." Derek nodded slowly and turned back to the clothes. Stiles had hoped that Derek asked because he wanted to stay for a little bit but he'd obviously misunderstood.

Stiles rolled over on his side and tried to make himself comfortable. It surprised him when a tear ran down his temple and hit the pillow. He didn't want to get emotional about this ordeal, so he squeezed his eyes shut to prevent himself from crying.

"I can stay for a couple of hours if you want?" Derek's voice reached his ear and made his heart skip a beat. "Yeah, okay." Stiles croaked out, shifting a little to make room for Derek behind him. With Derek's arm wrapped tightly around his waist and the warmth from his body on his back, Stiles fell asleep.

When he woke up from a knock on the door, Derek was gone. Stiles sighed and looked out the window. He wondered if Derek would come back sometime; if there were a chance that this would happen again. He noticed a piece of paper on the sill and jumped out of bed. It had not been there before. He picked it up and read it. The words made him smile. "You're mine now. Expect a knock on your window. D."
