"So all this was just a ploy to get me to suck you off in return?" Derek asked teasingly, not really caring if that was actually the case.

"No of course not. I've wanted your cock in my mouth for a while now. This is merely me reaping the benefits." Derek rolled his eyes while narrowing them at the same time, a feat really only capable of him.

"Oh don't act like you don't want a taste of this." Stiles gestured down as he joked. He did not know the truth of his words. Derek looked at the floor quickly, not wanting to give too much away. Stiles was not to be fooled,

"Oh I see how it is. You do want it." This realization seemed to make Stiles' entire being darken in desire.

"If you want it so bad why the fuck aren't you already on your knees begging?" Stiles was testing the waters, feeling how much he could get away with, but Derek was already three steps ahead of him. He wanted this. It was an intrinsic part of him, needing to please, to let go of his control for a little while. Who else could he trust with this other than Stiles, the one who'd saved him so many times, the one he'd saved just as much in return.

Derek dropped to the floor against the bed Stiles was sitting on. He scooted forward and nuzzled his face into Stiles' pants, letting out a mix of a growl and a purr.

"Oh fuck. Derek, you like that? Oh yeah you like that." A tiny whimper left Derek's throat and Stiles placed his hands around the back of Derek's head, shoving him further against his crotch. Derek moaned around the fabric of Stiles' pants and began to mouth around the rough material, wetting it. As his hands started to reach towards the zipper, Stiles swatted them away,

"No I don't think so. Keep your hands behind your back." Derek looked up at him with a confused frown.

"Oh don't worry, you can still suck my dick. Why don't you get it out," Stiles stared him down with a glint in his eye, "with your teeth."

Derek resisted the urge to scoff or roll his eyes and started to feel for the zipper with his tongue. His supernatural senses made it easier to yank the zipper down, push the boxers out of the way, and put his lips around Stiles' cock. Derek didn't waste any time. Hands still behind his back, he opened his mouth wide and pushed lips around and down to the base. He moved his mouth systematically in and out, quickly pushing forward and slowly sucking back, leaving no room for teasing.

"Oh my god you… Derek!" Stiles swiftly lost his cool as his hips stuttered forward. Derek loosened his jaw and allowed Stiles to fuck his mouth.

"All this time man who the fuck knew you were such a... a dirty fucking werewolf. Unhhh… Sourwolf I mean." With that Derek unclasped the hands behind his back to reach around Stiles' waist and pull him in closer.

"Your tongue, wow, I'm telling you that shit is magical. How do you even-" Derek popped his mouth off Stiles' cock, giving it one long lick from its base to its tip, pausing to swirl around and tongue the slit.

"Fuck. Derek I'm gonna come, okay. Okay? Derek?" Shoving down fast, he gave Stiles' dick one long last suck.

"Oh my go-od." Stiles came hard, pulsating into Derek's throat. He gulped as much as he could down, making slight choking sounds, some cum dripping through his lips, sliding to his chin. Stiles fell back onto his bed with a sigh and Derek followed, crawling upward until they were lying side by side. They shared matching blissed out faces. Stiles laughed and wiped his own cum off of Derek's chin and put his fingers to his lips, sucking it off.

"I can't believe we just did that oh my god, dude." Stiles semi-giggled. Derek gave him an amused eye roll and snuggled into his neck, feeling a little smug.

"I've been wanted to do that for a long time, but I didn't want to take advantage of your clearly innocent virtue."

"Hah. Well it took you long enough. I've tried every trick my very non-innocent, irresistible self knows. To the point where I may or may not have looked up the mating habits of the North American wolf. Don't you look at me like that! How could I not? I mean look at you. You're so… so…" Stiles babbled, making animated gestures with his hands. Derek looked up, lifting his head off Stiles' side.

"Me? More like look at you."

"What. No. What are you even talking ab-" Derek cut him off, putting his fingers on Stiles' mouth,

"You have stupid lips," he declared with a scowl. Stiles kissed Derek's fingers and muttered,

"Whatever you love it."

"Yeah. Well maybe I do."

And snuggled in the sheets, sated side by side, they fell asleep, happy.
