PART THRITY-FIVE

"Stiles, what did he do?" Derek asked, trying to divert the attention from Stiles arousal as best he could. His wolf was howling within, shredding his insides as he tried to press it into the cage in hell within his soul.

Stiles shifted to straddle Derek, and wiggled his hips a little bit.

"I will make you a deal, as soon as you cum, I will tell you." Stiles replied, smirking at the challenge he had placed on his alpha. Derek rolled his eyes.

"Insatiable." Derek muttered as he slammed his mouth down on Stiles'. His pace was unforgiving as his tongue darted into Stiles' mouth and took what was his, possessing and lapping at the warm wet mouth that had been wrapped around his dick not more than an hour ago. He nipped at Stiles' bottom lips, causing the smaller teen to gyrate and squirm in his lap, mixing the scent of Stiles' arousal with his own. He felt Stiles grind against him and moan, the friction of their bodies building his arousal more, making him hard again.

Derek reached down between the two of them and palmed Stiles' weeping penis, already slick with pre-cum and swollen with need and want. He rubbed Stiles roughly, adding pressure as his hand moved up and down. Stiles was moaning in his ear, his soft wet lips brushing Derek's ear lobe as Stiles opened his mouth and the delicious sounds poured from his lips. Stiles dug his finger tips into Derek's hard shoulders, squeezing hard and pushing Derek away, trying to force his body to take Derek's own pleasure. Derek felt Stiles wiggle on top of him and smirked at his ability to keep Stiles right on the edge of madness.

Derek felt Stiles finger digging into his flesh, the slight squeeze he felt that got tighter as Stiles orgasm built up. He could feel Stiles body tense slightly, knowing that Stiles was close and didn't want Stiles to cum like this. Derek stopped abruptly, and grabbed Stiles by the neck, yanking the lean boy down so that their lips were locked in a fierce kiss that seared the words in Stiles' throat, preventing the protests Derek knew were going to come from his teasing. He kept Stiles locked in his grip, nipping and biting at the smooth flesh before him, eyeing the soft neck of skin he longed to bite into.

He is ours, we already know that, why do you insist on being violent with him? Derek was asking his wolf, wondering why he felt the urge to tear Stiles apart even after he claimed Stiles as his mate.

The wolf growled with in him, rumbling and vibrating his whole body, though he was the only one who felt it.

He is the challenge we have longed for, but it's in my nature to force submission. The wolf growled back at Derek, clawing at the insides of the dark man, and making Derek wrinkle his face in pain and turn his head to the side so Stiles would not see.

Stiles noticed Derek's shift in position and began sucking gently at the tender skin of Derek's neck, taking the opportunity to bite down hard. Derek jumped at the obvious challenge to him and suppressed his wolf and the urge to draw first blood. He reveled in the feel of Stiles smooth, warm tongue lapping at his throat and tracing the lines of his jaw. He shut his eyes for a moment and let himself get lost in the feeling, relaxing and releasing the tension in his shoulders.

Stiles went back to Derek's lips and distracted the muscular man with the movement and elegance of the kiss, as Stiles slid a hand between them once more, palming Derek's impressive and straining erection. He was being gentle and slow and trying to provoke the wolf, and the rough nature the wolf brought with it. Stiles wanted the anger and passion in the sex and the urgency that the wolf brought. Stiles was teasing the wolf from Derek and playing with fire intentionally.

He knows what he is doing, he is strong enough, let me play! The wolf howled with in Derek, and inched it's way out of the cage in his soul, and Derek let the wolf out, but on a leash.

All at once, Stiles was surprised and extremely aroused as Derek's eyes shot open, glowing alpha red. The pupils were dialted and Stiles could see the ferocity and want behind them.

Derek grabbed his wrists, stopping the teasing motions and stood, keeping a grip on Stiles. He turned Stiles around and shoved him roughly into a tree trunk, the bark scratching Stiles' chest slightly as the younger teen hissed in pleasure and pain. Derek yanked Stiles' hips away from the tree and kept a hand on Stiles' neck, pinning Stiles to the tree.

"Stiles I'm still here, tell me to stop if you don't feel safe." Derek's voice came out the deep voice of the alpha, lined with the concern of his mate. Stiles was so horny and turned on now, he wanted anything the alpha could give him.

"Keep going." Stiles voice came out slightly high pitched and whiny, as he begged Derek to keep going.

With out warning, Derek pumped up Stiles shaft, using the pre-cum as lube and thrust himself into Stiles from behind. He felt Stiles clench around him from the surprise of being taken with out warning and he heard Stiles sounds of whimpering and pleasure. The wolf inside if him stopped trying to escape and reveled in the feel of being inside of its mate.

"Stiles, god you are tight." Derek was muttering through gritted teeth, willing himself not to cum until Stiles had. He thrust hard into Stiles, almost shoving Stiles flush with the tree. He kept a rough, teeth gritting pace and was trying to hold out as long as he could despite Stiles' pleas for him to cum and the seductive sounds of Stiles moaning and biting his lip to keep from screaming too loud. He let go of Stiles neck and held Stiles' hips steady as he picked up his pace, thrusting deep and hard, the feel of his skin slick against Stiles'.

Stiles kept his arms in front of himself, bracing against he tree and trying to keep from getting scratched by the rough bark.

"I'm about to …cum…don't stop." Stiles voice was coming out in huffs and short breaths as he felt his stomach and lower body tighten, a coil in his body tightening harder and harder.

Derek was moaning at the feel of Stiles tightening around him, seeing stars as he felt Stiles cum, and when he knew Stiles was on the edge, he kept going then released himself inside of Stiles.

They stood there for a while, breathing hard, sweating, Stiles bracing himself.

"My legs feel like Jell-o. We need to do this again….but can we not shred my clothes next time." Stiles mentioned sarcastically. Derek pulled Stiles' torso closer to his and leaned in to kiss Stiles' shoulder.

"Can we have that conversation after I pull out of you?" Derek chuckled. He leaned his hips away from Stiles and gently pulled out of Stiles. He felt Stiles wince slightly and took the hand of the younger teen. "I need a shower because I am covered in bitch blood and I want to get you dirty again." Derek leaned in and kissed Stiles, leading him back towards the house.
