The next day, Stiles laid on his bed, studying a text book, when he heard a sudden soft thump on the roof outside his window, a sound that used to startle him but that he knew all too well now. He looked over to the window as Derek slid it open and stepped inside. "Hey," Stiles greeted. "Hey," Derek replied. Derek walked over toward Stiles' bed. "What did Scott say?" Derek asked, knowing Stiles would understand.
"I uh... haven't told him yet…"
Derek just looked at him. "You know you're going to have to some time," he pointed out in his frank tone. "I know…" Stiles admitted. After a moment's pause, Derek sat down on the bed next to Stiles, a bit unsurely. He turned his head slowly to look at Stiles. Stiles looked slightly unsure himself. "So… How are Erica and Isaac doing…?" he asked—noticing that making casual conversation suddenly became much harder for them… "They're fine…" Derek answered. Stiles nodded in response.
After another moment of silence, Stiles spoke up, "So um… so my dad said he won't be home until eight so—just so you know…" he sputtered, regretting it a bit after he said it, as he felt suddenly very nervous and embarrassed.
Derek tilted his head and raised both his eyebrows at Stiles, "Are you suggesting something…?" he asked.
"Ah—I… um…"
Derek watched Stiles for a moment, simply enjoying his embarrassment, his expression still straight and reserved. Without thinking, he leaned a little closer to Stiles. Stiles leaned closer to him in return, and Derek suddenly noticed where the situation was going. But just as he did, Stiles touched his lips to Derek's, and Derek no longer hesitated.
With his lips still glued to Stiles', he reached his arm out and shoved all of Stiles' books and papers onto the floor in one swipe. Stiles was too distracted to even give him a sarcastic remark. Derek placed his hands on Stiles' waist and lifted him into the air, lying him down on the bed on his back gracefully.
He then wrapped his arms around Stiles' head, digging his nails into Stiles' hair, which was growing longer. Stiles suddenly lifted his arms, wrapping them around Derek's back and gripping him tightly, tangling his legs around Derek's also. He lifted his head up and pushed back against Derek, kissing him forcefully and flipping him over suddenly. He pulled back and Derek stared at him. "Sorry, Adderall…" Stiles murmured with a small, apologetic smile, "Think I might have taken a little too much this morning…" "Riiight…" Derek whispered. He flipped Stiles back over, sprawling on top of him, assuming control again, as only seemed natural. Stiles couldn't see himself topping the beast that was Derek.
Derek rubbed his nose against Stiles' for a brief moment, in a motion that seemed almost unconscious, but Stiles found it to be very sweet, and then he took the bottom of Stiles' shirt, lifting it over his head smoothly, tossing it in the corner of his room. He stroked his hands down Stiles' smooth and toned chest, beginning to nibble Stiles' neck lightly, careful to be very gentle on Stiles' human skin.
Stiles couldn't understand how Derek's mouth felt so amazing on his skin, but he wanted more. He closed his eyes, and breathed out a shaky breath. Derek stroked his lips over Stiles' chest, opening his mouth and letting out a low, satisfied growl, which vibrated against Stiles' skin and made him grab onto Derek's shirt, pulling it over his head, and then placing his hands flat on Derek's chest.
Derek's tongue made its way gracefully across Stiles' skin, and Stiles rested his head against Derek's soft black hair, running his fingers through it and grabbing hold of it every now and then. When he tugged on it, Derek gave a growl deep from his chest—a growl that said he liked it.
Derek lifted his head, and Stiles came face to face with Derek's glowing red eyes and sharp, shining fangs. "Oh my God…" Stiles startled and jumped slightly, looking down. Derek laughed, but it came out sounding so sexy, mixed with a wolf-like growl.
With that, Derek trailed his lips down Stiles' stomach, letting his lips stop right on top of Stiles' bulge. "Holy hell…" Stiles breathed quietly. He never would have imagined Derek would be like this, but then he thought of a time when Derek must've been the hottest guy in school… that on top of the animalistic instinct and confidence that coursed through his veins only made Stiles more excited.
He reached down slowly and put his palm on Derek's bulge in return. Derek groaned, and then bucked into Stiles' hand. He pulled Stiles' pants off slowly, throwing them all the way to the other side of the room as well. All that was left were Stiles' loose gray boxers, tight around his rapidly growing manhood, which Derek now took hold of lightly, squeezing gently. Stiles moaned, and his back arched. Derek's breath was stronger and heavier now, as he grabbed the top of Stiles' underwear, and then pulled down slowly, releasing Stiles' member. Stiles watched Derek as his tongue traced the tip of it very lightly, teasingly. Stiles gasped, gripping the covers. Derek loved Stiles' noises, and his reactions.
When Derek pulled back, Stiles gazed into his bright red eyes for a moment, and then he reached down and slid Derek's pants off.
"Hmmm… No underwear," Stiles said with a small smile. Derek gave him a big smirk. "I like it…" Stiles whispered. "Good…" Derek growled even quieter than Stiles, and laid his hips on top of Stiles', letting their members rub together as he thrusted against him. Both of them made gasping noises, moaning over and over. "Oh God Derek…" Stiles murmured hoarsely.
Derek grabbed both their members and began stroking, agonizingly slowly. Stiles' breathing became irregular, and Derek breathed unevenly. "Mmmm…" Derek sighed. His hand was soaked from their leaking members. After Stiles couldn't handle it anymore, he whispered, "Derek please… Please…" He wasn't sure why he was begging; he'd never imagined himself doing that before, but he just felt like it was his place… like it was natural…
Derek stared into Stiles' eyes, lowering his head, "What?" he asked in a husky voice.
"Just do it…" Stiles groaned, feeling himself growing wetter and wetter.
"Do what?" Derek asked in an equally rough voice. "Stiles…" He placed his lips against Stiles' incredibly hard manhood, "What do you want me to do?" he asked, as casually as if nothing was going on.
Stiles made a choked noise, "Fuck me, Derek!" he demanded finally, his member trembling.
Derek gave one final, defiant growl, before sitting up on his knees, pulling Stiles' spread open legs forcefully to him, placing his manhood against Stiles' entrance. He rubbed his again to get it slick and then pushed it in slowly.
Stiles closed his eyes and gripped Derek's hair tightly, pulling Derek to his bare, damp chest and making him groan deeply. He gave it a moment, and then he began thrusting in and out, rhythmically, but again very slowly, as if he enjoyed torturing Stiles. "God Derek… Yes…" Stiles moaned.
Derek was not as Stiles would have imagined—not that he had ever really imagined it before (heh…). He was somehow animalistic, as Stiles would've guessed, but at the same time, he was strangely gentle, passionate, and loving beneath the animalistic desire. It was perfect… Stiles could not have imagined a better lover…
"Faster… faster!" Stiles begged. Derek sped up gradually, and finally he was moving at a speed that set Stiles' body on fire. He was tingling inside, and he knew he wouldn't last long. Derek was so good… He wanted to do this forever. But the way Derek was going, there was no way. "Derek… It's so good… I'm close…" Stiles murmured, almost incoherently. But it was clear as day to Derek, and he breathed in Stiles' ear, his lips around them, his teeth biting down gently. Derek faught against himself every second—in fact harder every second—not to turn… His heart rate was flying, but if anyone had mastered lycanthropy, it was Derek. His eyes glowed red of course, and his nails and teeth grew a little sharper, though he fought back the rest.
Stiles had brought his hands up to grip Derek's beautiful, tan skin, feeling every strong muscle on his back move as he thrusted into Stiles. Stiles' head fell back on the pillow, eyes closed. He was not feeling anything except the heat building intensely. He dug into Derek's back, his nails leaving marks, and Derek didn't even seem to notice the pain—but he did react to the wonderful feeling of Stiles digging into him. Derek grabbed Stiles' manhood and stroked it, moved both his hips and his hands as fast as he could now, and Stiles flew over the edge so fast he barely had time to react. He felt everything tighten and then felt himself explode, shooting all over Derek as he yelled Derek's name. Derek leaned down to bite Stiles' lower lip, muffling him a little, though not because he didn't love the sound of Stiles' amazing scream of pleasure. Stiles bit back, harder than Derek, but then Derek hit his climax, and bit down hard onto Stiles' lip, a little stream of blood trickling down Stiles' mouth. Derek let out one final growl—almost purely animal this time—though it was mixed with Stiles' name.
Derek lay panting on top of Stiles for a moment as they caught their breath. "Oh. My. God… Remind me to do that with you more often…" Stiles said, seemingly still lost in another world. Derek smiled, "Oh I will…" he murmured, his warm breath on Stiles' face.
After a moment, he rolled off onto his side, still cuddled against Stiles' body. "Sorry…" he panted, "I can't help… being so close to you… It makes me feel… like I belong…" Stiles' heart skipped a beat, and he knew this was where he belonged, because there was no way Derek would say anything like that in this world or the next to anyone that he didn't truly mean it to…
"'S okay…" Stiles murmured, leaning his head against Derek's shoulder, "I like it too… Kinda has the same effect on me…"
Derek smiled to himself… He couldn't believe he was here like this. Maybe it wasn't what he had always envisioned for himself, but in some ways it was better. They laid against each other, silent for a long while, just enjoying the feeling, Stiles thinking of how he'd never felt so safe in his life, and Derek thinking of how he had never opened up like this—never enjoyed life so much… An incredible feeling of hope washed over him, something he hadn't felt in so long, that only this small, human, teenage boy next to him could bring.
