Author: This is NC-17. Like, for real. Essentially a PWP, but I consider it the smutty sequel to "Strange Encounters." My first foray into smut, so please be gentle. This part is John/Jim, with Jim/Seb to follow in the second part.
Sebastian didn't know how he had gotten himself here.
Really and truly, he didn't.
He had these moments often in his life, this sudden sensation as if he were floating slightly outside of his own consciousness and saying to himself, "What in blue perfect hell have you gotten yourself into this time, boy?" At first, he had blamed them on his own impetuousness. This was especially true during his military days, in which he often found himself at the business end of another man's gun for having made snarky remarks or for storming into a building before making sure it was empty. Or at least occupied by fewer than twenty men all bearing semi-automatic guns.
But lately, he had begun to think that maybe all those instances weren't really his fault. That maybe there was some deity just screwing with him for shits and giggles. Because, really, this couldn't possibly be his fault. No matter how hard he searched his memory did Sebastian ever recall a single instance where he ever uttered the phrase, "Yes, boss, I would love to watch you get your bat-shit crazy little brains screwed out of you by a man other than myself." Nor did he recall saying any variation of that phrase. Ever.
And yet here he was.
He supposed that, in the most narrow interpretation of events, it had all begun earlier that evening when he had received a text from Jim stating simply: My place. 15 Minutes. As always, Sebastian had become somewhat thrilled. Not like school-girl, squee and hop around thrilled, but an electric sort of thrill that went straight to his groin. The kind that made him want to fill that pretty little mouth of Jim's with his cock and thrust into it until that brilliant mind of his couldn't function for pleasure and oxygen deprivation. The kind of thrill that made him want to bend Jim over the table and dominate him so completely that Jim knew with complete and utter certainty which one of them was truly the master in the relationship.
So of course, Sebastian had rushed to Jim's and had arrived long before the scheduled time. He had punched the access code into the security system and entered the flat, anxiously searching to see if Jim was there already. He wasn't, so Sebastian had settled in his usual chair to wait.
He didn't have to wait long before he heard Jim's voice carrying up the stair well. The sounds he was making were strange, like a sort of cross between a giggle and a moan, and Sebastian tensed upon hearing it. For a moment, he considered running out to check and make sure that everything was alright, but then Jim removed that as an option by abruptly stumbling through the door with someone else clinging to the lapels of his suit. No, not someone else. That implied that the person was a stranger. No, the person currently rutting against Jim and tearing off a hideous jumper was none other than Doctor John Watson.
Jim somehow managed to disentangle his mouth from John's long enough to inform Sebastian of his role in that night's activities. "Seb, darling, I'm going to be shagging Johnny tonight, but I need you to watch and make sure he doesn't try killing me. Okay?" He didn't even wait for a response before tearing back into John, biting his neck and tugging at his ear lobe with his teeth. John groaned and reached a hand between Jim's legs to palm at his cock. Together, the two of them stumbled down the hallway and towards Jim's room, all the while stripping off layers of clothes. Sebastian merely followed a few steps behind, a slightly shell-shocked expression on his face as he watched the two collapse onto the bed in a pile of bare skin and limbs.
John pulled upward and away from the kiss, kneeling over top of Jim with a smirk playing at his lips. "You said you wanted it rough, right?"
"Yes, darling. Now get to it."
"Safeword?"
"Please, I won't use it." Jim was tugging impatiently at the hair on the back of John's head in an attempt to force him to get on with it.
"Well, I want one so that your bodyguard over there doesn't think I'm doing something you don't like and tries to intervene."
"Fine. The safeword is Gesundheit. Got it, Seb?"
Having Jim make direct eye contact with him while he was spread nude across the bed was about the most painful experience Sebastian could recall. It was all the could do to nod his assent when what he really wanted to do was throw John off the bed and plow into Jim hard, fast, and ruthlessly. Soon, however, Jim had turned his attention back on John and Sebastian was free to visually devour the man.
God, the sight was fucking beautiful. Poor word choice intended. Jim's hair was a disheveled mess atop his head, and his cheeks were colored pink with desire. His breath was coming in sharp pants as John's mouth cirlced around one of his nipples, drawing them up into flushed nubs. Sebastian watched as John's hand slid around Jim's cock, causing him to arch up into the touch while his mouth formed an O of gasped pleasure. John smirked and bit down on Jim's chest while he stroked his hand up and down Jim's cock. Jim was now panting heavily and thrusting into the touch while his own hands trailed over John's back and left little red streaks of fingernails across his skin.
"Sebastian," He was shocked out of his reverie by the sound of Jim's voice. He looked up to see that razor-sharp gaze focused on himself once again, despite the fact that Jim was still being jerked off by John. "Could you be a dear and get the lube and condoms out of the bathroom? Bottom left drawer."
Sebastian had to bite the inside of his cheek to keep from telling Jim to go get his own damn lube. He knew that doing so would only bring more trouble in the end, so he just accepted his task and left to retrieve the materials. He returned only a few moments later, but in the time he had gone the two men had shifted their positions so that Jim was on his hands and knees and John was kneeling between his spread legs. Sebastian walked in just in time to see John running his tongue from the base of Jim's cock and up around his arsehole. Jim gave something close to a growl of pleasure and pushed himself back into the the touch, encouraging John to explore further. John obliged him and began circling his tongue around Jim's entrance before pressing it slowly through the ring of muscles. He then closed his mouth over the hole and began sucking while plunging his tongue in and out of Jim. Sebastian watched the muscles in John's jaw work, all the while clenching his own jaw to prevent himself from saying anything about their activities. He simply dropped the lube and condoms on the edge of the bed before retreating back into his corner of the room.
Upon noticing that the supplies had been delivered, John pulled away from Jim with a wet pop that made a shudder run down Jim's spine before he began slicking his fingers up with lube. Then, without so much as a I-beg-your-pardon, he shoved two fingers into Jim's body. Jim gasped in shock at the intrusion, but then pressed himself into the touch, creating a rocking rhythm with the motion of John's fingers. It was only a few more moments before Jim was panting and demanding more. John ignored him and simply continued watching his fingers moving inside Jim's body, scissoring them open to stretch him further before plunging them as deep as they would go into Jim's hole. Upon hearing Jim's second demand for more, John acquiesced by forcing four fingers into Jim. Jim gave a strangled cry, dropping down onto his elbows as his body struggled to adjust to the stretch. His breathing was now ragged and irregular while John calmly waited for him to gain his bearings.
Slowly, John's fingers began to pull out of Jim. Sebastian was tempted to step behind John and grab his elbow, then force him to fuck Jim fast and hard with his fingers, like the man so obviously wanted. Despite the pain of taking too much at once, Jim's cock was still fully erect and begging for attention as it dripped precum onto the sheets. He moaned, dropping his head onto his forearms while John moved inside him, deliberately stroking his prostrate with each pass. Jim was thrusting back into the touch once again while one of his hands reached down to stroke his cock. John allowed it for a few moments before smacking his hand aside.
"Not yet. You don't get to come until I tell you to."
Jim gave a low growl of approval, encouraging John to take him, to dominate and overpower him. John seemed to agree, pulling his fingers out of Jim so he could unwrap a condom and pull it over his swelling erection. He then flipped Jim over onto his back once again and pulled his legs up around his shoulders. John positioned himself at Jim's entrance and thrust inward in one smooth motion. Jim gasped and his back arched as John drew out and then quickly shoved back in.
Sebastian watched as the two built up a rhythm. Watched as Jim writhed beneath John, wrapping his legs around John's waist and using his thigh muscles to force John to thrust in harder, faster deeper. He licked his lips as John bit into Jim's collarbone, suddenly becoming very aware of how painfully hard he was. He shifted awkwardly to try and better accommodate the bulging erection trapped in his trousers, but nothing seemed to help. Instead, it simply became worse as he watched John's pace pick up to a near punishing speed. Despite the way John was plowing into him, Jim was still panting and demanding that John take him harder. John tried to comply, but sweat was already dripping down his brow and back with the effort of maintaining their current pace. His breath was coming in harsh gasps, and it was obvious that he was attempting to hold off his own orgasm. Jim, however, didn't seem to care and continued forcing John to press deeper into himself. With a groan, John's hips picked up a stuttering, jerky motion as he spilled himself into Jim.
Jim waited for John to pull out and remove his condom before he curled his legs tighter around John's waist and rolled. With that simple motion, he was on top and John was splayed helplessly beneath him, quickly fading into his post-orgasmic haze. Jim straddled John's chest, his knees pressed into the mattress directly below John's arms. He then gripped the headboard with one hand and the back of John's head with the other, forcing John's neck to arch and head to raise as Jim pushed his aching cock into John's mouth. He groaned, his eyes falling closed as he began thrusting into John, all the while holding John's head so he had to take it all. John was swallowing around Jim's cock as best as he could, his throat working to accommodate him, but still an occasional gag was pulled out of him as Jim pushed deeper into his mouth. Jim was now panting harshly, his climax fast approaching. He groaned, thrusting frantically twice more into John's mouth before his orgasm hit with enough force to make him yell out.
Sebastian stood quietly in the corner while the two disentangled themselves and sprawled across the bed, neither touching the other. Jim's eyes fell closed while his chest began to ease into its usual easy rhythms. John, meanwhile, was staring up at the ceiling while he attempted to regain his composure. They simply laid there like that for a long moment, neither speaking while they laid in the afterglow of sex. This lasted until Jim suddenly sat up and, without preamble, shoved John off his bed. John hit the floor with a startled "Oof" before jumping to his feet and glaring at Jim.
"What was that?"
"Oh, I'm sorry; I thought you were just here for the sex. Or would you like a good post-coital cuddle?" Jim asked derisively.
"No, but I'd rather not get shoved around by a pipsqueak like you."
John was already collecting his clothes off the floor, thanks the gods, and pulling them back over his nude body. Jim merely stretched across the bed as if flaunting the fact that he didn't have to get dressed. He smirked slightly while running his fingers through his hair.
"Sebastian, could you be a dear and drive Johnny boy home? I'm a bit too tired to do it myself."
Sebastian scowled, but nodded nevertheless. He was beginning to wonder if there was something he wouldn't do for Jim. Possibly anything that included dealing with children. Either way, he had now signed himself up for escort services despite the fact that he had a raging erection in his trousers which was threatening to become problematic if it wasn't taken care of soon. He sighed and wondered out into the lounge to wait for John to finish sorting out his clothing. John followed shortly thereafter, raking his fingers through his hair in an attempt to straighten it out. He gave Sebastian a "lead the way" sort of smile and followed him out the door and into the night air.
