I do not own Teen Wolf!

A/N: Thank you for reading and reviewing! This is going to be the last chapter. Hope you enjoy it!

Previously:

His own hand reached out to grip his cock, he was in sensory overload and he needed to be touched.

He froze his self exploration as he heard Derek growl against his skin. "No touching. I will be the one to make you cum. And it will be as I'm fucking you and you are begging for release." He inserted a spit covered finger gently inside of Stiles to emphasize his point. "Do you understand?" All Stiles could do was nod.

Now:

Derek stopped briefly, earning a frustrated growl from the younger boy. He leaned over to pull open the night table drawer and was pleased to find what he was looking for.

Stiles heard the distinct sound of a bottle snap open and realized immediately and gratefully that Derek had found his lube. As excited as he was, he was a bit nervous about the pain.

It wasn't long before he once again felt a strong finger against his entrance; this time however, it slid it with very little trouble. He squirmed slightly at the foreign feeling but found himself enjoying it, too turned on to be uncomfortable.

His breath caught in his throat as Derek added another finger into his tight hole, and he almost lost it when he inserted a third. "Derek!" he gasped out as the werewolf hit the bundle of nerves he was searching for, causing Stiles' body to tighten and his cock to pulse.

"Please Derek, I need….I need you." He could almost feel the older man smirk from behind him; he half expected a smart ass comment in return but was instead rewarded with another brush up against his prostate. Derek loved the way Stiles moaned and tightened around his fingers in pleasure. But as great as that was, they both wanted, no, needed more.

Stiles whined as he felt Derek remove his fingers and he tilted his head to peer over his shoulder at the man behind him. He was rewarded with the incredible sight of the Alpha covering his massive cock in a shiny layer of lube. Stiles gulped slightly, in both nervous and excited energy as he realized what was coming next.

He felt the head of Derek's cock press up against his entrance as the man paused. "Are you sure you want this? This is your last chance to ask me to stop." Derek's voice was sincere and completely out of character, and Stiles appreciated the sentiment. "Yes I'm sure." The boy spoke, his voice rough from lust. "If I remember correctly…"Stiles spoke with an air of shameless lust. "You promised to fuck me until I begged for release." He arched his back in anticipation, pressing back against Derek, a smirk on his gorgeous lips.

That was all the permission Derek needed before gripping the young man's hip firmly as he gently eased his way inside. He growled and hissed at the tight hot entrance gripping his cock; it took every ounce he had not to fuck the boy like an animal. His wolf howled from inside, threatening to escape.

"God, Derek! You're so fucking big." Derek tightened his grip at the young man's words, both not caring that bruises would inevitably form there. He gave Stiles a few seconds to relax before he started moving slowly further inside, stopping only when he was flush against the young man's skin.

"Derek…Please…move…I need….Fuck me!" Derek wasted no time in obeying Stiles' commands. He started thrusting into him hard and deep, making sure to brush against his prostate as often as he could.

As previously promised Stiles was being fucked so hard and good and couldn't help the begging that escaped his lips. Normally he would be embarrassed at the sounds he was making and the vulnerable tone evident in his voice; but right now his only priority was pleasing Derek and getting release.

"Derek, touch me! I need to cum! You fuck so good…I need it…I need you…make me cum hard. I want to cum because of you." Derek moaned at the words. He always knew that Stiles' mouth would be the death of him, he just didn't know how.

Derek leaned forward until his sweaty chest pressed against Stiles' back, allowing his hand to slip over the warm skin. He stopped when his fingers found the hot wanting flesh between the young man's legs. He could hear the blood pulsing with desire and when he wrapped his large hand around the warm skin they both moaned out in content.

Derek started stroking Stiles in the same rhythm as he was pounding into his warm tight ass. It didn't take long before he felt Stiles choke out a brief warning before his whole body tightened and he released stream upon stream of warm sticky cum.

Stiles entire body clenched down around Derek's cock and that was all that it took before he too was sent over the edge. He felt his release explode into Stiles, filling him up. Stiles felt his cock twitch at the feeling of Derek's cum as they both collapsed onto the bed.

The room was silent except for the sounds of rapid heart beats and heaving chests. Stiles was thankful for his fan as the cool air hit their physically spent, overheated bodies.

Stiles was the first to break the silence; unsurprisingly. "Ready for round two?"
