Prey

Jim noted with boredom that Sebastian was in a good mood when he came home that day, and it was true. Sebastian was elated, practically manic from the insanity of what had just happened. He just had to plan how he was going to get Doctor Watson alone. He couldn't bring him back to the house, not after what had happened last time. Fortunately, he knew lots of secluded places where nobody could hear you scream. Some of them even had beds. And he could enlist help if needed.

Several weeks went by before he had a night off and could pull off his plan. He just needed to make sure that it didn't alert the attention of Jim or Sherlock.

John hadn't forgotten about Sebastian's "reward," and as the days turned into weeks, he became increasingly jumpy.

One Friday night, John he the clinic late to find a familiar Audi waiting for him. Sebastian. He was surprised, then, when two men he'd never seen before stepped out and grabbed him before he could run. They blindfolded John, bound his hands and feet with zip ties, and bundled him into the car.

John prayed to God that this was Sebastian's doing. When his face hit the leather of the car's seat, he growled, and tried kicking at his captors, writhing his bound wrists behind his back. "Let me go! Who the hell are you?"

Sebastian was in the driver's seat. He cracked a grin as the men gripped the struggling doctor. Oh, this was too fun.

John's heart was pounding as the car took off. He prayed to God that this was Sebastian's doing. He signaled one of the men to gag him, and watched through the rearview mirror as they shoved a gag into the writhing man's mouth. He took the longer route to their destination, enjoying John's muffled noises and the sight of him helpless. And this was just the appetizer.

John yelled and struggled and cursed into the gag, but it did no good. He had been rendered immobile and he couldn't make a single intelligible syllable. He paused only briefly when he felt the car slow to a stop before he resumed his struggling.

Sebastian maneuvered himself out of the car, being careful to hide his erection from the other men. He nodded a thanks to them, then grabbed John and hauled him over his shoulders, carried him inside the building and enjoying the feel of John's arse under his hands in the meantime.

John continued to squirm and yell into the gag. There was only one man now, and he was positive that it was Sebastian, the way the man kept grabbing at him. Knowing the two of them were finally together and alone, John could feel his erection slowly starting to come on.

Sebastian felt John's erection press against his back and laughed. "Ohh, John, is that what you think this is? You are so wrong..." He was really being evil, Sebastian chided himself. But he wanted John to properly scared, at least at first.

John's stomach churned. What did he mean that's not what this was?

Sebastian opened the door to a room and flopped John down onto the bed, then rolled him onto his stomach and immediately tied his wrists to his ankles, hogtying him. He whipped off John's blindfold, then raised John's chin with his hand so that John's neck was craned up uncomfortably to look at him. "Well, John. Here we are...and how are you feeling?"

John gave him an indignant look and bit hard on the gag. He wanted to know what the hell was going on. He wanted this to be all fun and games, and he was still excited, but there was a twinge of real fear beneath it all.

"Staying quiet, huh? Well, I kept my word, didn't I? I hunted you down..." Sebastian reached into his pocket and pulled out his gun, casually loading the gun with bullets. "And as someone who enjoys the thrill of the chase, I was a bit disappointed: you were such easy prey." He clicked the cylinder back in place and stroked the gun down John's face. "Were you really so lonely and horny that you never bothered to wonder if your enemy's right hand man might not want what he said he wanted?"

John's stomach lurched and plummeted downwards as Sebastian stroked the gun down the other side of his face. Oh my God...what had he done? Sebastian was right. Had he really been that lonely and desperate? He had. His heartbeat quickened, but this time it wasn't because of arousal—his erection was gone. He bit down hard on the gag. Was this how he was going to die? Tied up and gagged in a location he didn't even know? He glared up at Sebastian, jerking away from the gun.

"I was hoping the hunt would go along a bit longer...so here's what's going to happen, John," Sebastian said, setting down his gun for a moment as he pulled out a cigarette and lit up, puffing on it. "I'm going to untie you, and we're going to fight hand to hand. If I win, I get to do whatever I want to you." He winked, then ripped off his t-shirt, revealing his taut muscles and his large biceps. "If you win, well, I guess it's too bad for me." Sebastian knew that there was some risk that John might buy into this all the way and actually try to kill him. He was fairly confident he could take the man, but the risk made it all the more fun. He held up the gun for John to see, put the safety on the gun, and then tossed it out into the hallway, then locked the door. He leaned down and kissed John's temple gently, giving it a small lick. "It seems a shame to let you go...you're so pretty tied up." He released the ties from John's wrists and ankles and pulled off his gag.

John growled and immediately pushed himself up and off the bed, lunging at Sebastian before the other man had too much of a chance to prepare himself. John hit him low and knocked him backwards onto the floor.

Sebastian laughed and groaned as his back scraped against his still-healing wound. "Got more fight in you than I thought! The short ones always end up surprising you," he barked a laugh and used a free hand to toss John off of him, rolling up onto his knees as John scrambled to his feet. He bent his knees, waiting for Sebastian to strike. His hands clenched and unclenched into fists—he wasn't sure if he should go bare knuckle or open palm.

Sebastian leisurely got to his feet and walked towards John, then grabbed him into a chokehold as John tried to take a swing at him. "I had expected a bit more fight, but beggars can't be choosers..." he said as he wrestled John back toward the bed.

John lashed a leg backwards to kick Sebastian's groin and let out a choked sound as he tried to struggle away. Sebastian doubled over in pain, letting John go momentarily. "You'll pay for that," he growled, then pounced on John, tackling him to the bed.

John was strong, there was no doubt about it, but Sebastian was far stronger. The kiss had reassured him that this was a game, albeit a slightly terrifying one. Part of John wanted to just let Sebastian win, but at the same time, he didn't want to just give in, and was fairly certain the bigger man would be victorious anyway. He tried struggling away, but Sebastian wrestled John's arms behind him and lashed them together again. He rolled John onto his back and straddled him.

"Admit it. You're helpless." He reached into his pocket and pulled out a large Bowie knife, spinning it in his hands.

John clenched his jaw, breathing heavily through his nose, but didn't say anything as he looked up at Sebastian. He still didn't trust Sebastian, not at all, but the sight of him shirtless and twirling a knife above him was undeniably hot.

Sebastian held the knife in his teeth as he untucked John's shirt, then grabbed the knife and began slicing through the shirt underneath with the knife, letting the cold metal trail along John's skin.

John's breath quickened and he sucked in his stomach as the cold metal slid against his skin. Sebastian yanked the ruined shirt apart, running his hands hungrily over John's bare chest. His finger traced the scar in John's shoulder, once again fascinated by it, then leaned down to begin kissing and biting at John's throat, breathing heavily, the knife point touching against John's stomach. "Say it. Say you're helpless," he commanded.

John closed his eyes as Sebastian's lips met his neck and bit back a moan, suddenly back in the mood, and whispered breathily, "I'm helpless..."

"Damn straight," Sebastian breathed, kissing John hungrily again, clawing his hands down John's chest and grinding his hips against John's. "And because you're so helpless, my little trapped animal, it would be best if you followed orders from here on out. Right?" The last question was steely and menacing.

John's breathing hitched, catching in his throat but he nodded, trying to keep up with Sebastian's kiss. He arched his back away as the nails left angry red marks down his torso. "Yes—" Oh God—why was he so turned on by this? John couldn't help thinking that if the man started pulling rank, he'd finish before Sebastian had even properly touched him.

"Good boy," he growled into John's mouth. "Now I'm going to untie you. Don't make me regret it. If you disobey there's going to be consequences, and you're not going to like them." He raised his hips so John could twist himself around and bare his wrists, which Sebastian unloosed. "Lie still on your back."

John nodded, his heart pounding, and slipped his arms out from behind him to let them lay loosely at his side as he moved back onto his back, unmoving.

Sebastian kneeled, straddling John but not touching him, then began unbuckling John's trousers and unzipping them. "Raise your hips and look at me."

John gasped and his eyes locked with Sebastian's, watching with heavy breath as Sebastian let his hands trail slowly down John's hips and thighs and pushed off John's trousers, never looking away. "I'm going to fuck you until you can't walk straight. I cannot wait to get in that tight arse of yours."

"F-fuck..." John gasped. He had no desire to not be able to walk straight, but at the same time—Jesus Christ that was hot. He didn't think he'd be able to get the words out to protest, anyway.

Once he'd yanked John's trousers off and cast them on the floor, Sebastian attacked John's hip bone and lower stomach with his lips and teeth, sucking at the skin, licking down to the waistband of John's pants and yanking them down with his teeth, using his hands to help and stroke at John's hips and arse.

John squirmed and gasped and moaned. He knew Sebastian had told him to stay still, but he couldn't help but move his hands to curl in Sebastian's hair as his erection sprang out from the confines of his pants. "God!"

Sebastian sprang up and seized John by the throat, pinning him to the bed as his lips hovered over John's. "You were supposed to lie. Still." He grabbed a handful of John's pubic hair and twisted it painfully. "And when you address me, you'll call me 'Colonel.' I outrank you, and I think I've earned some respect."

Oh fuck. John's surprised gasp of pain turned into a choked, aroused, whimper. He tried to take in a raspy breath, his hands going to try and pry the other's man's hand from his throat and choked out, "Yes, Colonel, sir—"

"That's better, soldier," he smirked, releasing John's throat. "Now undress me, and make it sexy, but don't waste my time!" He rolled onto his back, looking over John's body for the first time. God, he looked good. He was impressed with his own ability to wait this long to get this far. The anticipation was driving him mad. "And get the rest of your shirt off," he tacked on, as it was still hanging around John's arms.

John quickly scrambled up to his knees, shrugging the shirt off and tossing it to the floor. He swung around so that he was straddling Sebastian and leaned down, pressing his hardened cock against the other man and licked a line up his neck. "Yes, Colonel," he murmured in the other's ear, making Sebastian grin.

His shirt was already off, which was a start. John kissed down his chest. When John's lips reached his navel, he nipped lightly just beneath it, then moved his mouth back up to suck at Sebastian's pulse point while he yanked out the other man's belt.

Sebastian tipped his head back, groaning. God, yes. He gripped John's thighs, his heart pounding. "It may be impressive to ordinary civilians that you're a captain, but in here, I own you. You are mine," he groaned, raising his hips so John could remove his belt.

John's eyes fluttered at his words and he moved his mouth to deeply kiss Sebastian, draping the belt around his own neck. He undid the button and zip on his trousers, before slipping a hand in to grasp firmly at his cock before he moved backwards to tug his trousers and pants off in one go.

Sebastian groaned at John's touch, then kicked off his clothes the rest of the way, yanking on the belt around John's neck to pull him in for another kiss, exploring John's mouth. He ran a hand down John's bare back, feeling light traces of scars, though not nearly so many as his own. Sebastian's hand traveled down to his arse, grabbing it and pulling John's hips to his, panting as their groins rubbed against each other.

"Nnngh!" John moaned as he rutted against the other man, slipping his tongue desperately into Sebastian's mouth. He wanted so badly to hate the man. That would make everything so much easier. He wanted to be able to just shoot him here and now in cold blood, but there was no way he would be able to do that. At Sebastian's touch, he practically melted into a desperate, obedient, puddle of shame and longing. If he wasn't so completely drunken on lust, he'd be horrified.

The sounds John was making were intoxicating. Sebastian grabbed his shoulders and rolled him over until he was on his back, move to straddle him again. His dog tags dangled over John chest as he leaned down and kissed him again, then sucked down John's torso to his cock, licking up it while locking eyes with John, then taking him in his mouth, locking his lips tightly around him.

John shuddered and gasped, involuntarily bucking his hips up. "Uhh—fffuuuhh—Colonel—" John choked out as his fingers went back to Sebastian's hair, his eyes locking with the other man's.

He pulled John's cock in until his nose was buried in John's pubic hair. He gave it a long suck before slowly pulling out with a wet pop. "Wouldn't want you coming too soon...we both know how worked up captains can get around their superiors." He licked off some precome and reached over to grab some things—a condom, lube, and a cock ring, then tossed the condom to John. "Put this on me." He slipped the cock ring around John's cock, giving his balls a massaging squeeze.

John winced and pushed his hips up to grind against Sebastian again before he grabbed the condom, opening it with his teeth and then rolled it on to the other man's length, his fingers teasing and brushing against him an unnecessary amount.

Sebastian's breath was shallow as John touched him. Once he was finished, he growled animalistically and seized John's legs, forcing them up, then slicked his hand with lube and began massaging at John's hole, sliding one finger in, then two, scissoring the space. "You're so tight, John—" he breathed. "Never had a colonel's cock in there before, have you?" He added three fingers, twisting them in and brushing against John's prostate.

John didn't admit that yes, he in fact had; it had been a one night thing back in Afghanistan. Instead he groaned out, "No, Colonel…" Fireworks exploded behind John's eyes as he pushed against his prostate, and John bucked back against him as best he could, wanting and needing more.

Sebastian curled his fingertips, adding more pressure to the prostate, then pulled them out a bit and drove them in again, watching John's face hungrily. "Who do you belong to, Captain Watson?" He pulled out his fingers and pushed his cock in, gasping as John's warm tightness encircled him. "Who do you belong to?"

"You!" he cried out, his mouth opening wide, his eyes squeezing shut as Sebastian thrust in. It had been about two years since he'd been with a man and it hurt. Sebastian had prepped him a bit, but his prick was quite a bit bigger than a few fingers. He winced and grit his teeth as his muscles clenched around the other man, getting stretched and used to the feeling.

Sebastian waited inside John as the spasms past. He should've worn a cock ring himself—he'd have to focus to keep from coming too soon. Oh God, it felt so good to be inside John. He was becoming undone himself. Everything about John had him infatuated. He gripped John's knees as he pulled partially out and thrust in again, starting slowly, moaning. "That's right, John—you're mine. I don't care who you work for, I don't care what side you're on, right now, you're all mine. And you like it, don't you? You love it that I'm ruling you—" he thrust in a bit faster now, the intense pleasure escalating. He hit against John's prostate which each thrust.

John couldn't even form a coherent sentence, every time he opened his mouth it turned to a loud, low moan or a pleasured, gasping groan. He spread his legs wider and hooked a finger in Sebastian's dog tags, pulling him close for a bruising kiss. "Yesss..." he murmured into his mouth, because God, he did.

Sebastian met John's lips eagerly, running his hands all over John's skin, wanting to touch him everywhere at once. He'd never felt like this during sex. It had always been about satisfying his cock and being done with it. This was—his whole body needed John's whole body. He pulled out nearly all the way and began driving into John with long, deep thrusts. "If you want to come—" he said raggedly, "You'll have to beg me for it. I won't take the ring off until you beg."

John groaned and dug his nails into Sebastian's back, clawing across them, "You're a—a fucking cheeky bastard," he panted in between gasps. He arched his back up, his knees tucked near his shoulders and bit hard on Sebastian's lower lip, slowly dragging it out.

He moaned as John's teeth sunk in, then dug his nail into John's scar. "I didn't hear a 'Colonel' in that sentence," he sang.

John winced and tried jerking his shoulder away from the nail digging into the tender flesh, 'You're a fucking cheeky bastard, Colonel-' he growled, which turned into a moan.

"Better," Sebastian gasped, then gripped John's knees as he thrust as quickly as he could, plowing into John, moaning out loudly. "God—John!"

"Harder!" John cried out, the pleasure inside him building into what was going to be his most intense orgasm of recent memory, but the cock ring was denying him.

Sebastian thrust as hard as he could, impaling John, grabbing his hips and shoving them up to meet him. He swiveled his hips so he hit John at a new angle each time, sending shivers down his own spine. He wasn't going to be able to hold on much longer. He held the base of his cock for a few moments, then began thrusting in again, sending the bed violently knocking against the well. "Beg for it!"

John couldn't stand it anymore. "Please! Fuck—please, Colonel, let me come! Please! I need it!"

Sebastian pulled off the cock ring, thrusting in as fast as he could once more, sweat tricking down his forehead. He finally thrust in one final time, coming hard and yelling.

John came soon after, come shooting over his stomach, his every nerve exploding with sensation. "Sebastian!" he yelled out, then fell back onto the bed, exhausted and gasping for air.

"John—" Sebastian breathed, holding the condom carefully as he pulled out, then discarded it and fell on the bed next to him. "God..." He breathed, catching his breath.

Sebastian grabbed John's jaw and pulled him close to kiss him. "Mmmmm...you are delicious, Captain."

John weakly kissed back, one hand moving to cup his face before his fell back onto the bed, eyes closing. "And you're still a bastard." His heavy breathing turned into a chuckle as one hand went to rest on his chest.

"I did what I promised...I'd call that being a man of his word." He grinned, then rolled off the bed to grab a pack of cigarettes and lighter before climbing back in beside John, pulling him so he was resting on his chest, then lit up and exhaled a plume of smoke.

John grinned and curled against him. His eyes closed and his grin faded. He was content, there was no doubt about it, but it was so wrong...he didn't know how they would be able to keep doing this...but he didn't know that he could stop, either. "What're we doing...?" he asked, the question directed at both of them.

Sebastian took a long drag of his cigarette and looked down at John. He'd put off the thought purposefully for several days. It had been easy to forget tonight, in the heat of the moment. John was just John. Now, though, he had to come to terms with the fact that John was still the enemy. He could be ordered to kill him, or his best friend, and what would happen if he refused? "I don't know," he admitted. He ran a hand through John's hair, soothingly. He'd never felt this way about anyone before. There was no easy solution to this mess they'd made. He closed his eyes. He refused to worry about it right now.
