**Sorry it's been so long, don't ask... Anyway, here's the smut. This chapter is pretty much why it's rated M. So if you don't like it, don't read it. Really, the fic could be considered complete without it, if you aren't into the smut. Otherwise, enjoy the consummation of their matehood ;)**
Stiles woke up suddenly, his body covered in sweat. His heart was racing, and his skin was slick. Tossing the light covers off of himself, he noticed that they were drenched in sweat as well. Scott was still lying on the other side of the bed, the graceful curves of his lean body rising and falling as he breathed. He was emanating heat like a furnace in his sleep, his tanned skin radiating supernatural werewolf warmth as his body worked overtime to finish healing itself. Stiles' hand unconsciously reached out, tracing the sweaty curves of Scott's ribcage with his finger. It was an act of possessiveness, like shining an expensive piece of silver; Stiles was hardly able to believe that Scott actually loved him. His third eye sleepily squinted open, surveying the wolf in front of him. He could see the wounds healing deep inside his body. He was nearly finished. Contented that Scott was safe, Stiles' third eye went back to sleep.
The pale boy stood, wrenching his sights away from the man in his bed. He padded across the floor, the carpet soft beneath his bare feet. As he threw open the window, cool air rushed past his body and into the hot room. The fresh, earthy smell called to Stiles, beckoning him. Summer rain was falling outside, making background noise for Stiles' labored breathing. He shivered, but told himself that it was just the sweat cooling off in the air. He'd been dreaming of wolves.
Sighing, he turned around and headed back toward his bed. Their ordeal was over. For now, anyway. Stiles reminded himself that they could relax. Looking up, he noticed that Scott was sitting up, his dark eyes intent on Stiles. For a moment, the intensity of his stare made Stiles pause, looking at the tanned boy with trepidation. But in the darkness, he saw an amused smile playing on the boy's lips, their crooked angle matching his jaw. He reached out and drew Stiles into his arms, bringing him onto the bed so their skin pressed together. Their lips met, passion exciting their movements as they kissed fervently. Stiles shivered again. This time, however, Scott's skin burning against his own took away any excuse he had of the cold.
The two boys pulled apart, each smiling in the dark. Stiles traced a finger along his mate's broad, tanned chest, following the paths of his energy. Scott grinned again, laying his head down on his mate's shoulder and listening to his heart beating within him. "Stiles?" he whispered, trying not to break the perfect chemistry flowing between them. He heard the boy's heart skip a beat at hearing Scott say his name.
"Yes?" Stiles said, continuing to trace the flow of energy down his side, making the boy twitch beneath his touch.
"So you're my mate now, right?" he asked, having already supplied the answer earlier that day.
"Of course," Stiles replied, bringing his eyes up to Scott's.
"And mates usually..." Scott started, realizing he didn't know how to finish eloquently. He raised his eyebrows, a bemused expression on his face as he waited to see Stiles' response.
"Mate?" Stiles filled in, eliciting a laugh from Scott.
"Yes, mates usually mate," he said, resting a broad hand on the small of the pale boy's back.
"So you want to... mate?" Stiles asked, following Scott's train of logic.
Scott smiled sheepishly. "I mean..." he stammered, not wanting to pressure Stiles. "I haven't technically claimed you as my mate until... I mean, my scent isn't really-" Scott stopped short, feeling awkward describing the bestial nature of werewolf relations.
His mate calmed the tanned boy by responding to him with a kiss on his lips. Stiles could feel the hot rushes of energy pulsating through his boyfriend's body. His soft lips followed the heat coming through his skin, finding the sensitive spots on the boy's body. He tasted Scott's sweet skin, hearing the low moans rumbling inside his chest as his lips paused where the energy pooled at his sensitive brown nipples, hairy, sweaty armpits, and taut navel. Scott settled backwards, resting his head against the wall behind him as Stiles' tongue followed the hairy little path down from his bellybutton. Stiles adjusted himself so that he was on all fours, his head bent down over Scott's pelvis. Scott was laying down on the bed, his torso supported by the wall behind him.
From his vantage point, Stiles could smell the sweaty, musky scent of Scott's torn black briefs, the claw marks giving him ample skin to inhale. His body recognized his mate's pheromones, causing a visceral reaction within him. His every nerve ending screamed for the boy. His skin suddenly became sensitive to even the tiniest brushes of Scott's dark leg hair on his arm. His tongue started salivating at the scent of Scott's manhood. His eyes could see the boy clearly, even in the dark. His body knew Scott, and after all these years, it was starving for him.
Scott could sense the change in Stiles. He heard the prickling goosebumps rising on his skin, saw the slight changes in his posture as he went from want to need, and, above all, he could smell Stiles' body screaming for Scott's attention. Scott's wolf took over, his feral senses urging him to fulfill his mate's needs. His fingers reached almost unconsciously for the greatest source of the smell, sliding past the waistband of his red boxer-briefs and grabbing one of his cheeks. He extended his claws, quickly ripping through the material so that it fell off of his mate's body, removing the obstacle between him and that which he needed. Carefully retracting his claws, his blunt fingers searched hungrily over the boy's skin. Finally, one digit plunged into the boy. Instead of feeling relief, Scott felt urged on ever more.
Meanwhile, Stiles had burned off Scott's underwear, using some of the heat of the moment to reduce them to ashes. His fingers grasped at Scott's thigh and pelvis, needing to feel him. His mouth wrapped around the wet, uncut head, tasting the already hard member. The exposed skin tasted like Scott's pheromones as he buried the six inches deep in his throat. Scott's dark pubic hair scratched up and down Stiles' cheek as he pumped up and down on the meat, Scott's hips lifting to welcome the warm, inviting lips.
Stiles' moans reverberated against Scott's cock head as the boy's tanned fingers found his prostate. The pale boy arched his back, digging the fingers deeper inside of him. Scott smiled, knitting one hand through Stiles' hair. In response, Stiles groped his pec with one hand, tweaking his dark nipple with a magical touch of his palm. He could feel Scott's moaning breaths beneath his hand as he felt the tanned flesh of his hard pec. Stiles' lips tightened in response, heightening the sensations.
The pale boy practically whimpered when Scott removed his fingers from his hole, feeling the hand also release from his head. All at once, he felt strong hands on his sides, lifting him up and pulling the dick from his mouth, only to flip him right side up and lower him slowly onto the wet cock. Stiles' naked toes curled as lightning flashed outside, and felt the warm, spit covered member enter him. Scott held his breath as he slowly set the boy down on his cock, feeling his mate from the inside. Once Scott was fully inside of Stiles, the boy took over. Putting his feet on either side of Scott's knees, he used the strength of his leg muscles and a little levitation magic to start lifting himself up and down, impaling himself on Scott's member. He felt Scott's soft lips on his neck as he rose and fell, feeling his boyfriend deep inside of himself. Tan, loving hands grasped at his body, one on his chest and the other on his hip, radiating warmth.
Stiles' erection bounced and bobbed, hitting him occasionally on the stomach as he worked Scott's dick. His mate's hand slid from his hip, across his pelvis, and caught the nodding member, holding his fist still so that Stiles' cock would slide in and out of it as he worked Scott's shaft. As he rose in the air, Scott's hand jerked his cock, squeezing around the sensitive head. As he lowered down, Scott's thick cock rammed his prostate, making him see stars. His body alternated between pleasurable sensations, Stiles' magical abilities naturally pulling him and pushing him as it sought out Scott's skin.
Suddenly, Stiles felt a deep rumble starting in Scott's abdomen. He could feel energy spreading out from this location, squarely in the center of his mate. Explosive rivers of energy flowed through the boy's body in every direction, making his arms and legs tingle, his nipples tighten, his throat release a long, virile howl, and his cock erupted inside of Stiles. The pale boy could feel the electric energy flowing within the boy, pulsating beneath the surface of his skin. It flowed outward through the two available outlets: his erection and his mouth. In a moment of pure togetherness, Stiles felt some of the energy flow into his body, entwining the two through their point of contact on the deepest level. This energy found its way into his system, flowing through his body as well and making him cum at the same time as his boyfriend. Their two bodies were in perfect sync. Scott had officially claimed Stiles as his mate, and the howl had been an unconscious declaration to the rest of the world, though only understood by any wolves within earshot. In return Stiles' third eye lit up on his forehead in the form of a blue crescent moon.
Outside, a massive bolt of lightening cracked through the night, lighting up the world and making a sound that rivaled Scott's deafening roar. They could both feel the displacement of air from the powerful strike. Stiles twisted his body to the side and turned his head to face his mate. As the sound poured from Scott's fanged mouth, Stiles could see the flow of energy leaving his lips. His third eye could see bright spots on everything in sight that Scott had ever touched, the air he had breathed, the thoughts floating through the air that he had created in his liftetime. Stiles' body recognized the call of his mate, and responded. Stiles' entire body appeared glowing to his third eye, as did Scott's. Their skin glowed the same indefinable color, something out of the ordinary spectrum; they officially belonged to one another.
After a few more moments, the color faded from the world. Stiles' eye ceased to glow, and it closed his preternatural view of the world. Scott's howl faded and his face's lines softened back to the gentle, human visage that Stiles had come to know and love. Their heartbeats returned to normal paces, as did their breathing. Both boys collapsed, their bodies intertwining with one another to fit naturally together. Laying on the bed, their eyes held each other, having lost of sense of intensity and now simply sharing the pleasant moment. Silence filled the room, leaving only the sound of chirping frogs and rain coming from the window to act as a soundtrack to their shared amorous thoughts.
A gust of wind pushed wet, chilled night air through the window, bringing the smell of wet earth into the room. Stiles' skin rose in little bumps and he wrapped his limbs more tightly around the supernaturally warm wolf. Closing his eyes and curling his head under Scott's chin, Stiles started to drift into sleep.
"Are you cold?" Scott asked, and he could feel the boy's warm arm leave his side to search for a blanket.
"No," he replied quickly, causing Scott to return his arm to Stiles' side. "You're warm enough. You're all that I need."
**So I could wrap it up with an epilogue after this, or I could keep going. If I keep going, I'm worried the story might stretch too far and stop being good. Updates may also be... unpredictable. This could be a good point to end it. Anyway, comment with your opinion, after a few days I'll decide how to proceed!**
