UGH! you guys have no idea how hard ( innuendo! haha) it was to write this. My brain! Anyways here you all are! The rest of the smut.

The mid-day air was thick and heavy between the two bodies writhing on the bed. Stiles gasped as Derek flipped him onto his quick thump of adrenaline is still making everything feel jittery and unreal. But Stiles lets Derek lay his hands on his skin, grip tight and haul him down the bed, mouth hot and open on his chest, wet against his throat - and then pressed hard against his own mouth.

Derek's still sliding his hands on Stiles like he doesn't think he's allowed.

"I want to fuck you," Derek says, gravely and rough. "Tell me I can do that, tell me you want that." It sounds more like a demand than a question, but Stiles doesn't even care. All he wants is Derek to keep touching him.

"Yeah," Stiles breathed out." Just please, don't stop." Derek let his hands travel down Stiles' body, stopping at his hips. He felt Derek's hands slip his boxers off. He reached over to the nightstand and came back with a small bottle of lube. Stiles let out a small moan as he felt Derek's first slick finger massage his opening. It continued for a few more moments, trying to get Stiles to relax before he pushed the first finger inside. Stiles stiffened at first before a moan slipped from his mouth.

"Oh god, I want you inside me so bad." Stiles couldn't help the grunt as a second finger was added. There was a slight burning from being stretched, nothing he couldn't deal with. The pain soon turned into flares of pleasure as Derek worked his fingers in and out of Stiles' body. As a third finger was added Stiles felt a spike in the pleasure when Derek's fingers brushed against the small bundle of nerves inside him. Stiles yelled out, seeing stars as pleasure rippled through his body. Derek leaned back, pulling his fingers from the boy's body. Stiles let out a whimper, feeling empty and needy. He looked back in time to see Derek slicking himself up. 'That's a sight I could get used to.' Stiles thought. A smile spread wide on his face as Derek grabbed onto his hips.

"Tell me if you need to stop. No matter what, if you need me too, I'll stop." Derek looked in Stiles' lust blown eyes, his own lust showing and something else that Stiles really didn't have the brain power to think about. Stiles nodded. Pushing back against Derek with a needy moan. At first all he could feel was the burning stretch as Derek pushed in slow and steady. When Derek was in all the way he looked down to stiles in concern.

"I'm fine, just give me a few seconds." Stiles mumbled out. About a minute passed when Stiles turned back and nodded, telling Derek he could move.

With the first few thrust Derek kept them slow and soft, not wanting to hurt his love. He tighten his grip on his mates hips, trying to keep himself under control. Derek let out a growl as he increased his movement, setting a slow and shallow pace. Stiles let out a gasp as the tip of Derek's member brushed against his prostate. He felt Derek tighten his hold and move faster, cause Stiles to throw his head back and let out a strangled moan.

"Faster... Ahh.. Please Derek... Ah fuck! I need you. Please go faster." Stiles pushed back insistently on Derek's cock, feeling it brush against his prostate again. He wanted to come so bad, needed Derek to go faster and harder. Derek pulled out, leaving Stiles to squawk and huff in protest.

"Get on your knees and stop complaining." Derek chuckled out as he watched Stiles got up and kneeled on the bed. Derek grabbed his hands and placed them on the headboard before pushing back into Stiles' body. Stiles let out a scream as Derek slammed right into his prostate. Derek started up a fast and hard pace, feeling Stiles shake with need. Stiles' breaths coming out in uneven puffs as Derek pounded into him, causing the bed to knock against the wall in noisy thumps. Stiles reached around back and grabbed his head, bringing him forward, latching his mouth to Derek's. The kiss was wet and sloppy though neither of them really seemed to mind at the moment. Derek pulled out again, leaving Stiles empty and frustrated. He took Stiles in his arm and laid down, pulling his mate down on top of him. Stiles seemed to get his motives and to Derek's cock in his hand, moving it to his entrance. They let out a similar grown as Stiles sank down onto Derek's dick. Stiles leaned down and kissed Derek as he started to move up and down Derek's length. They could feel their orgasms building as Stiles increased his speed, slamming down on Derek and hitting his prostate with every thrust. Derek gripped tight on Stiles' hips, thrusting his hips in time with Stiles'.

"Oh, oh…" he moaned, and Derek sped up his hips and wrapped his fingers around Stiles' shaft. Derek pumped his fist at a different speed than his hips, and Stiles felt his orgasm growing closer, his balls tightening and desire pooling low in his belly. Then, Derek squeezed his fist and hit Stiles in just the right spot, and white exploded behind Stiles' eyelids as he came with Derek's name on his lips. Derek kept pumping his fist until Stiles' cock was sensitive, and he reached down and stilled his hand.

Derek pushed Stiles' boneless body down and leaned over him. Stiles cried out at Derek picked up the tempo of his thrusts, hitting the bundle of nerves with every one. A low growl vibrated through the alpha as he came, emptying out into Stiles with his eyes closed tight. When Derek opened his eyes, they were red and Stiles thought it was so sexy his body automatically contracted around Derek's cock.

"Oh man, that was awesome. We should totally do that more often. In fact I think we should do that again in... about 15 minutes or so. Just - Mhhf" Stiles cut off as Derek captured his mouth in a deep kiss.

"Yes, we can do it again. But I need you to shut up for a few minutes." Derek mumbled as he rolled over. Stiles draped his body across Derek's, nuzzling into the werewolf's chest. He yawned as the warm glow of the sun came through the window and rested on his back. ' A nap wouldn't hurt either I guess' Stiles thought to himself, as his eyelids grew heave and slipped closed.

Derek looked down at the human and smirked. " So much for round two." Derek chuckled as he rolled onto his side, tucking Stiles in under his arms. Derek buried his face in the back of Stiles neck and drifted off to sleep.

Omg! Finally done! Ok I'm taking a nap now. I want to sleep for like a week after this!
