Chapter 2 – Late Night Surprise

Derek lowered his head again and attacked Dean's slightly kiss swollen lips. He nipped at the lush lower lip while Dean shifted restlessly under him. Derek tugged on Dean's lip, causing Dean to arch up in response.

Dean snarled slightly, unable to just lie there and take it. He arched up into the kiss and rolled his hips while he yanked at Derek's hair in an attempt to unseat the wolf. He knew he needed to gain the upper hand in this scenario because he wasn't anyone's bitch and he wasn't about to become one now. If they were going to do this, he sure as hell wasn't going to be the bottom in this . . . whatever the hell this thing between them was.

Derek, however, didn't move an inch except to snarl back with flashing blue eyes. His wolf enthusiastically accepted the challenge that his bedmate unknowingly issued. He grabbed Dean's wrists and yanked them above the hunter's head, pinning the hunter's hands down to the bed besides the hunter's head.

"Back off, dog," Dean hissed irritably. "I don't bottom."

Derek smirked with menacing humor then taunted huskily, "I didn't ask." His lips captured his prey's threatening growl easily and his tongue nimbly slipped back into the hunter's mouth to reclaim his territory. His wolf rumbled low with pleasure at the responding groan it elicited from his reluctant hunter. He opened his eyes and the tense body under him slowly relaxed into subconscious submission.

Dean felt spellbound by the glowing blue orbs piercing into his soul. His mind flicked to instinct as he returned this dominating kiss with increasing passion because, if there was one thing he knew, it was how to kiss. It came to him so naturally, it was automatic. With his fighting mind turned off, he could only feel and what he felt was indescribable. It should be against some kind of natural order that this wolf could make him feel so much better than any woman he'd ever been with.

His increasing desire flared hot inside him. It had been a while since he'd last let go this much. In fact, it had last been with Derek but that hadn't been real. It'd been . . .

A cloth ripping sounded through the silent evening which made him aware that the slight tugging at his boxers had ended. Razor sharp nails barely raked his now very bare hips. He hissed slightly at the pain but couldn't deny his throbbing cock twitched excitedly at the aggressive behavior.

He yanked his head away from the kiss and griped snidely, "All you had to do was ask, wolf boy. Clothes don't grow on trees, you know."

"I liked this way better," Derek rasped forcefully against Dean's neck while he planted kisses down it. He kept Dean's hands trapped in one of his hands against Dean's weak attempts to free them. His other hand smoothed a path down Dean's arm and on to his chest.

As one of the wolf's hands brushed over Dean's left nipple, he let out a pleasured gasp which caused Derek's hand to deviate from its planned course. Instead, the hand came back up and an index finger slowly circled around the now pebbled nipple while Dean shifted restlessly.

He couldn't remember his nipple ever being this sensitive before. He honestly didn't know whether he wanted to arch into Derek's fingers or away from them. Each brush of skin against it, each pass of breath against it, shot lightning bolts straight down into his groin, increasing his arousal exponentially.

He twisted and turned indecisively which increased Derek's fascination with that body part. Derek's hot mouth slid over the sensitive, pert nipple and Dean instantly bucked up into the delicious warmth. Then the rough buds on Derek's tongue brushed over and around his aroused nipple while Derek's other hand latched onto his right nipple.

Dean arched and wiggled under the wolf at the intense sensations, unable to lie passively. He yanked his hands free and managed to get them down to grab Derek's hair when the damn wolf sucked at the captured nipple like a starving baby. He honestly couldn't decide whether to yank the wolf away or pull him closer.

With a defeated groan, Dean pulled the wolf's mouth closer to him and arched without inhibition. His bowlegs bowed out even more then moved up to encircle the wolf who settled between them like it was the wolf's den. Like it was meant to be.

Normally Dean would have flinched and pulled away at that thought but there was way too many pleasurable sensations flowing through him right now to hold on to any deep thoughts. He groaned again at the nipping bite on his tender nipple and thrusted his hips up into the wolf's jean clad groin. He growled softly at the two slightly pained pleasures but he wanted, needed, more. He wanted skin on skin contact, even though he knew he'd probably freak slightly at the feel of another man's penis next to his.

Even so, he snapped out huskily, "Off." He yanked slightly on a belt loop to let the wolf know what he meant. His hand moved to unbutton the jeans in question.

Derek lifted off of his sorely abused nipple a moment to glance into Dean's eyes. Glowing blue meet emerald green for a moment before Derek's hand left the nipple it had primed and Derek's mouth took that newly tender bud into its wet heat. Derek sucked it down as deep as he could then nipped lightly at the pert tip.

Dean groaned without knowing what caused it, whether it was again the pained pleasure or disappointment at being denied what he'd asked for. He bucked his groin up again for contact and felt Derek's hand brush past. He felt it brush his cock again before his mind put together that Derek was actually taking off his jeans as Dean had asked.

Derek shifted up slightly to ease his jeans down but didn't let go of Dean's nipple in the process. The new angle tugged the tender bud even more, causing Dean to arch up into it and he felt Dean's cock leak against his. He shuffled his legs to help the jeans slide down and off his legs. Finally, he kicked off the hindering clothing.

Derek reached up and grabbed Dean's pecs firmly as his mouth once again took possession of Dean's. Dean groaned deeply at the firm pressure on his chest combined with the heat and rough brush of Derek's hands over his primed nipples. He swallowed around Derek's probing tongue and arched up again. Simultaneous, Derek rolled his hips down, dead center on Dean's cock.

Dean instantly felt the damp, silky slide of warm, fat cock against warm, fat cock which caused his own cock to twitch, batting at Derek's, who immediately pressed down even more firmly into Dean's hips. He felt like he was going to orgasm already and this was barely third base. When Derek rolled his hips yet again, Dean suddenly needed way more air than he could get from Derek's mouth. He yanked away with a gasp, "Fuck!"

"Plan on it," Derek promised into his ear with a husky growl before he lowered his lips back down to Dean's chest.

"Shit," Dean cursed violently, bucking up into Derek's rolling hips. He really wanted to argue, positions, if nothing else, but Derek wouldn't let up on his onslaught. He felt more nips at his tender bud while Derek sucked and twirled each one in his mouth.

Dean's mind failed to form words anymore. He just gripped Derek's hair and held on to the wolf, letting someone else take the wheel for one of the few times in his life. He vaguely wondered if Derek was always this forceful when he had sex then quickly decided that he didn't care as long as the wolf kept it up tonight.

He felt Derek lift up and latch onto the other nipple causing him to yank insistently on the wolf's hair. He warned tautly, "Fuck! Enough! I'm about to cum, damn it."

He felt an amused chuff against the sensitive bud right before a hand slide down between his legs then a probing finger slowly circled his equally sensitive entrance. Automatically, he tried to close his legs but with the wolf between them, he only pulled him in tighter. He was too far gone to change what was going to happen now, as much as he hated to acknowledge it.

Also, he must have zoned out at some time because there was a slick, dampness in the area and on the finger and he didn't remember Derek lubing either of them up. He tried to remember but Derek distracted him with soothing circles around his rim muscle, relaxing him more than he'd like to admit. He finally gathered his wits and started to ask Derek about lubrication when he felt Derek's thick finger breech him then slowly slide into him as deep as it could.

"Shit," he moaned softly. He felt like his inner muscles had just been parted like a hot knife through butter. Yeah, it was a weird feeling with a bit of a sting to it, reminding him vaguely of a time not too long ago. This time, however, he was a lot more aware of it. The intrusion felt strange and invasive but also sort of good in a way.

"All ready for me, aren't you?" Derek husked out against Dean's mouth.

Dean felt Derek's finger retreat then thrust back in, forcing a groan out of him. He didn't know why. It still felt like an invasion, only with some intense, possibly pleasurable, sensations building with each thrust. As his muscles relaxed, and he relaxed, his mind focused on the pleasure slowly growing inside him again. It quickly reminded him of the last night they had together and he knew this time would be even better.

Derek licked and lapped at his nipple while he added another finger inside Dean and soon Dean's hips matched the prepping thrusts of Derek's finger. In no time at all, according to Dean's pleasured mind, Derek was up to three fingers and his other nipple was now being laved at. Dean couldn't stop rolling his hips to impale himself on those fingers, trying to get them deeper, but instinctively knowing he needed something else to get to deep enough inside him.

"Derek, more," he hissed out desperately. "Damn it. Please." He couldn't add anymore as he pressed his hips down again, only to groan in disappointment. Instead of the more he'd requested, he felt the wonderful fingers leave him. He started growling in frustrated impatience.

Derek's wolf snarled slightly in answer which Dean sensed he should cow to the larger, stronger wolf but he wasn't that kind of person. He snarled back in response then felt Derek bite down lightly at his left nipple while simultaneously he was forcefully penetrated by what could only be Derek's huge cock. He hissed in pain and instinctively tried to move away. "Shit!"

Unfortunately for Dean, his aggressive behavior had set off Derek's wolf nature and Derek's wolf wasn't about to let this hunter get away from him. It could smell Dean's arousal and had inhaled it long enough that there was no way he would allow the hunter any give at all. It only understood kill, or dominate. It knew Derek didn't want to kill anyone, especially this human, so this was its only other choice.

The wolf's hands grabbed Dean's hips and yanked him down firmly onto his thick cock. The wolf was in control now so it continued to thrust and rut inside Dean until it had firmly bottomed out inside his hunter. It pinned the hunter under him and waited for the human to accept his domination. He felt the hunter totally relax under him when it paused to the onslaught so its chest rumbled lightly in appreciation of his prey's submission.

Dean felt like he'd initially been speared open by the wolf's huge cock. He had tried to move his ass out of the danger zone, only to have the wolf continuously thrust inside of him. But the pain slowly subsided and it began to feel much better once Dean relaxed his muscles and stopped fighting what was happening.

Derek stilled deep inside of him and Dean looked up into the wolf's eyes. They stared at each other a long moment. Dean felt the throbbing cock deep inside him, where no one else had ever been, and tried to fight the emotion it brought. Starring into the wolf's eye helped distract him until Derek finally asked softly, "Better?"

Dean exhaled slowly then nodded. Derek's lips meet Dean's halfway as they kissed fiercely. Derek slowly pulled his hips back until he was just barely inside Dean then thrusted back deep inside the hunter, his hunter, as his tongue did the same to Dean's mouth. Derek kept up the two rhythms, synchronizing them together, until Dean had to break away to breathe.

Dean reluctantly yanked his head away, gasping for air, while Derek continued to kiss down Dean's neck. All Dean could do was hang on for the ride. Derek once again latched onto his nipples while each deep thrust of his hips pressed Derek's stomach down onto Dean's own engorged cock.

"Fuck! There. Right there. Shit!" Dean exclaimed with pleasure at the new position.

Derek's movement angled his cock to spear right into a spot that set off even more fireworks within Dean's body. Between Derek sucking and nipping his tender, perky nipples, Derek's cock plowing deep down into Dean's deep secret spot and those toned abs pressing down and sliding up and over Dean's cock, Dean wasn't going to last very long. His whole body hummed with mind-numbing pleasure.

"Shit," he cursed hoarsely, "Fuck! Derek, I'm close."

Derek only sucked harder at his chest, eliciting another pleasured groan out of his hunter. He knew he couldn't take much more then Derek increased his pace and the force of his thrusts. He was about to shot his load. He felt his balls tightening moments before it seemed, to Dean, at least, that Derek's cock was growing even more.

That sensation was enough to pull Dean back from the edge. There was no way he could take more cock, even if he wanted to. Derek had size to begin with and if he was getting bigger, oh, hell, no.

"Derek," he panted breathlessly, trying to calm the panic that threatened. "What the . . ."

"Shit!" Derek hissed out in an incredulous pant. "Dean. Shit. I . . . Fuck!"

Derek's thrusts became more forceful and Dean groaned at that extra stretch which was becoming more painful with each thrust. He, they, needed to stop. Now! He couldn't . . . "Derek. I can't. St . . . Shit!"

Derek's last thrust split him in two, from his ass, right up the middle. Dean was sure of it when the searing pain speared him again from down below. He bucked up, pushed at the planted wolf while he hissed in reaction. But, his actions caused the bulbous cock inside him to rub against that oversensitive spot inside him once again.

His first mind-blowing orgasm ripped throughout his body and babbling mouth milliseconds after his sore ass was ripped apart. He'd barely gotten his curse out when his balls pulled up painfully tight against his body and expelled everything in them all over his, and Derek's stomachs. His sore, split ass throbbed and pulsed around the wolf's engorged cock erupting inside him simultaneously. His entire body twitched with violent muscle spasms in response to the best orgasm that had ever gripped him while he shuddered underneath the powerful wolf.

"Fuck. Fuck. Fuck," Dean swore out hoarsely in a mindless litany, only vaguely aware of Derek's echoing curses.

Meanwhile, hot spurts of the wolf's cum shot inside him and he shivered slightly as he felt the wolf fill him up. He could definitely feel the wolf's cum painting his insides while he tried to get his breath and mind back together. He always thought he'd be repulsed by this, another man's cock shooting cum inside of him. But, for some reason, with this wolf, it seemed so right. In fact, he could still feel his muscles pulsing around the extra thick cock inside of him, like his body was instinctively milking the wolf for all he was worth.

Derek pressed up inside him more but didn't pull out. He just kept pressing and rutting against Dean's sore, overstuffed hole. With each movement, it rubbed against that secret pleasure spot inside Dean and in no time, Dean was rutting right back at him. He felt his limp cock slowly fill but Derek's still hadn't stopped spurting hot cum deep inside of Dean.

Dean slowly reached a hand down to grab his own cock and help himself out but Derek sensed his movement and caught the hand. He firmly trapped it back against the bed above Dean's head. Dean huffed out wearily and asked curiously, "You going to give a hand then?"

"No," Derek husked out against Dean's lips. "You came untouched from just my cock inside you earlier. I want you to do it again." Then he captured Dean's lips in a consuming kiss while he continued his sensual attack on the very susceptible hunter.

"Seriously?" Dean whined out incredulously when Derek finally allowed him to breathe again. Derek arched his eyebrow in response which only had Dean rolling his eyes slightly. Derek lowered his head to attack Dean's neck and chest again.

A few moments, Dean's cock was hard and heavy between his legs again and Dean pushed up against Derek's abs while pressing down onto Derek's still thick cock. He soon realized that he had very limited range of motion because every movement away from Derek's huge cock, pulled at his rim muscles. He frowned heavily as a very disturbing thought came to him.

"Hey, uh, Derek?"

"Yeah," Derek rasped out distractedly before attacking another one of Dean's nipples.

Dean let out a pleasured sigh before he remembered and asked hesitantly, "I know you don't become a real wolf and all, but do you, like, have any wolf-type parts? You know, besides the teeth and hair."

"Not now," Derek evaded firmly then captured Dean's lips in another mind-consuming kiss. The new position allowed Derek's abs to once again rub against Dean's heavy cock. Dean's cum from his previous orgasm added lubrication and soon Dean flew over the edge again with Derek's cock still cuming inside him.

"Damn," Dean rasped out hoarsely before wearily closing his eyes a moment. Soon as he got his breath back, he would ask Derek. Soon as he got his breath back and remembered, he would ask . . .

"Dean," Derek prodded with a soft husky voice. All he got in return was a soft snore, for which he was thankful. He really had no idea what had just happened so he had no answers for Dean's questions. Maybe tomorrow he'd have some ideas.

"Dean," Derek's sleepy, slightly irritated voice rumbled low and deep in his ear, waking Dean from a very peaceful, definitely not long enough, sleep. "Answer your phone."

Dean groaned unhappily as he became aware of the heavy metal rifts blaring from his cell phone. His right arm and hand flailed a couple of times at the bedside table before he finally managed to snag the current torture device assaulting his ears. He fumbled with it slightly then finally opened the line. "What?" He snapped out with weary frustration.

"Dean," his little brother's voice barked out firmly with frustrated anger, even though Dean could also hear relief mixed in there too.

"Sammy? What the hell do you want? Wait. You okay?" He growled out at first before his normal, manic concern took over again.

"What the – Yeah, I'm fine. Perfect. Worried about you. Where the hell are you? Are you injured? Tell me where you are right now," Sam snapped out in rapid succession.

"What the . . . Calm down, Samantha. I'm fine," Dean quickly assured his brother as he moved his hips to sit up, only to be stopped by a literal blinding pain in his ass. He hissed briefly before swallowing down the pain.

"You ARE hurt," Sam accused irately. "How bad? Where are you? And don't lie to me."

"No! No, I'm not. Just made the mistake of turning on the lights with a blinding hangover," he quickly adlibbed. He spotted Derek's piercing eyes boring into his from over his shoulder as he continued to assure his worried brother.

"Honestly. Only scratches on me are from this, um, lady that," he lowered his voice slightly, "um, apparently is still here. So, um, I, uh, oh, God," he groaned with aroused surprise then shut his mouth against the pained moan that threatened as Derek once again attacked his very sore nipples. He learned last night that Derek, or he, had some kind of nipple fetish because the wolf went out of its way to suck, tug, and pull on them to the point where they were very swollen and raw.

He wasn't sure what the flash in Derek's eyes prior to this attack meant, whether Derek was upset over being called a girl, or being ignored, or jealous, or just plain bored. He also didn't have a lot of time to contemplate it, considering the vigor of Derek's attack and the direction of Derek's hand which was currently stoking down his chest toward his half-hard morning wood that was becoming harder by the moment. At the rate Derek was moving on his body, he needed to get Sam off the phone quickly, for both their sanities.

"Think you woke her up," Dean gasped out hoarsely.

"Seriously, Dean," Sam griped with irritated disgust.

"Hey, it's not me, dude. I mean, it is me. Because I am seriously that hot but it's not like I can turn it off," he trailed off with a low groan because Derek's hand enclosed his fully engorged, weeping cock and that was just plain torturous, especially since he couldn't do anything about it while his little brother was on the phone with him. Yes, he did actually have some restraint, and morals, just not many.

"Oh, gross," Sam complained piously. "Look, just give me a call when you head out. Okay?"

"Sure thing, Sammy. Might be a few hours, though," Dean moaned hoarsely and barely moved his phone out of the way before Derek sealed his lips in a fierce kiss. He barely heard Sam's disgusted gripe before Derek closed his phone for him.

He didn't care what happened to it after that, although he did hear a thud on the floor next to the bed. All he cared about was the increasingly pleasant desire coursing through his body once again. He moaned into Derek's mouth as he wound his hands into the dark, lustrous hair of his partner, knowing he'd stopped caring early on last night that his bedmate wasn't human or female. He vaguely wondered if he was becoming addicted to the wolf, but quickly discounted it.

Derek's hand pulled him down to his back on the bed and he didn't fight it. The wolf swiftly covered him and, once again, he felt Derek enter his sore body then move deep inside of him in a rhythm that they practiced quite a lot last night. As expected, the soreness soon gave way to intense pleasure until they both came hard.
