Ok so this is the first time I've ever done this trio as a couple and the first time I've ever done a body switch this complicated... I 'am so sorry if this is terrible but I'm trying! In case you didn't already figure it out this is a McSpirk aka Spock/Kirk/Bones aka MxMxM if you do not like please do not read. Rating will go up as story continues and if I owned Star Trek it would have gone in a very different direction...anyway enjoy! please review! I love feedback and suggestions!

"Beam us up Scotty!"
"Spock duck!"
"Doctor!"
"Scotty!"
"A'm trying Cap'in! Somethn gone wrong with the transporter!"
Jim, Spock and McCoy were fighting for their lives on the planet below the Enterprise. They beamed down to the new planet in an attempt at convincing them to join the Federation. The "people" of the planet appeared to be squid like mermaid-people with wings! Squid fairies as Kirk named them. It was an interesting planet to say the least. So when the trio walked instead of flew into the village court which was actually more of a lanai the entire court gasped and they all knew it was not a good sign. Unfortunately the 2 men and the half-Vulcan did not know that they were walking on the planets sacred burial grounds hence why all the other court members were floating...oops. Needless to say the natives were not happy and thus the gun fire began. The trio booked it out of the village Kirk immediately trying to hail the Enterprise so Scotty could get them the hell outta dodge!
"Gotcha Captain!"
3 forms started to phase in and out of the transporter room but Scotty knew it was taking too long for them to appear. Something was wrong! Another intensely terrifying minute later and the 3 bodies solidified on their transporter pads. Scotty let out a deep breath.
"Ye alrighi Captain?" The 3 men on the transporter pads were starring at each other like they'd lost their minds.
The body of Kirk answered first "uh...ya Scotty we're fine. Why don't you...uh go take a break!...It's been a long day. Go take a breather."
Scotty knew something was off but hell if he knew what! With that Scotty gave a simple nod and left. The second the doors swished closed the ranting began.
"Ok...what in the hell happened?!" Screamed Kirk...well at least the body of Kirk. Inside that body was the mind and soul of none other than Dr. Leonard McCoy...
"Captain Doctor I believe there was a crossing in the transporter beams thus causing us to switch bodies." Spock's stoic voice coming from McCoy's body was surely a sight to see.
"Obviously you hobgoblin!" It almost hurt Spock to see his Captain insulting him, illogically so, since he knew it was not really his Captain and that McCoy never actually meant any harm from his insults. He figured out a long time ago that the insults were more of an endearment than anything else.
"Calm down Bones!" Said the incredibly expressive half-Vulcan body with the mind of Jim Kirk, "Lets just get out of here and get down to sickbay so we can figure out how to reverse this." They silently walked to sickbay and immediately locked themselves into McCoy's office upon arrival.
"Ok so lets get this straight; I'm...I mean...Wait…ok so Kirk's mind is in Spock's body. Spock's mind is in my or McCoy's body and my mind aka McCoy's mind is in Kirk's body...right?"
"Affirmative." /odd/
"Yep." /this is so cool I'm the sexy Vulcan...wait...sexy?...uhm.../
"Great...that's what I thought..." /hell...I wonder what Spock thinks of my body...not that way you pervert! Calm down!/
"Ok so what? Are we in some old Terrain Disney movie where if we admit our true feelings or spend a day in each other's shoes or maybe even learn something we would never learn otherwise we'll magically trade back to our bodies? Or is this one of those sciency things were we have to do brain surgery on ourselves or find the impossible cure in order to change back?" Asked Spock's body but Kirk's mind.
"Logically Captain science should be the answer."
"Of course logic cures everything doesn't it Spock." Growled McCoy in Kirk's body. He thought for a second.../this could be the perfect time to tell them my feelings for them both...or I could ruin everything and transfer.../ "Jim maybe we should try both options? Draw a few blood samples see if anything is hinky while simultaneously pretending to be whomever's body we are in so we can learn a life lesson or whatever... That way which ever happens first gets us outta this mess faster!" McCoy wouldn't admit it but he was always curious what it would be like to really be Jim for a day.
"Ok." /this could get messy.../ "Let's just take the blood samples and figure out how we are going to pretend to be one another. I mean I may be a genius but I'm not you Spock. And Bones you might have to break your code of ethics as the Captain when deciding who lives and who dies..."
"You think I don't know that Jim?! And what the HELL is Spock gonna do? He can't perform surgery on anyone!"
"Bones calm down I was just trying to point out that this won't be easy. Maybe we should sneak off to my quarters" he points to his chest then realizes his mistake "uh I mean the Captains quarters and have a little get to know you kinda night?"
"Logi-..." Spock pauses, if he has to pretend to be Dr. McCoy he has to act it "Sure thing Jim." He manages to give a slight southern drawl not as thick as the real McCoy's but it'll work for now. He grins to himself as his own body and the Captains stare back at him amazed.
Still shocked the other two just follow Spock's lead toward the Captains quarters.

Three and a half hours later Spock has McCoy down packed minus the swearing because even now he can't bring himself to do it. He knows enough medical terminology and technique to hopefully get by as long as nothing major happens.
Kirk is struggling terribly at maintaining an emotionless face for Spock's body and still can't get his speech correct. Spock would never use slang and its killing Kirk.
McCoy seems to be having fun pretending to be Kirk. He even dramatically pretended to flirt with anything that moves. After said 'show' Spock has a question:
"Tell me...Jim...do those techni- I mean pick up lines ever work?" McCoy starts laughing at the gain and loss of the fake Georgian accent throughout Spock's question.
"Well Mr. Spock as 'Captain' anything I say works but" he was just gonna lay it on thick pretending to be Jim but he decides for some unknown reason to tell Spock the truth "but for myself personally no not really. Haven't really been with anyone since my divorce." He tried to laugh it off but the look on Spock's or uh his face stopped him.
Spock or maybe just McCoy's body seemed to frown at this:
"I can't imagine why Doctor. You are an incredibly educated and medically talented individual. Likewise many of the crew have spoken highly of your physical beauty as well." Jim and Bones are silent did Spock really just complement him?!
"Wow Spock that's the nicest thing anyone's ever said about me."
"Illogical. Emotion has nothing to do with it. I am merely stating facts."
/so it's a fact to him that I'm not only smart but also beautiful? Cool!/
Kirk seemed to think it was time to break up the little silent soul starring contest Spock and McCoy were having for an unknown reason it sent a little pang to his heart to see his best friends becoming better friends without him.
/calm down its probably just nerves...it's not like your jealous...right?/
"I have a question." When he was met with two questioning stares and silence he continued "Ok so what do we do if we don't know the answer to something that our bodies selves would usually know or if something happens that we can't handle? We can't just stop what we are doing to go find each other and ask it'll get suspicious and incredibly dangerous."
"Well 'Mr. Spock' we could keep our communicators on us?" Said Bones in his best Captain tone.
"Illogical 'Captain'. We cannot simply call one another when we need help. It would as you humans say "turn many heads"?" Kirk replied in his best so far Spock monotone.
"Actually gentlemen I believe I have a better idea." Spock drawled on his new found Georgia accent. McCoy wouldn't say it out loud but it looked like Spock was enjoying being in his body.
/not that way pervert! Get your mind out of the gutter and focus!/
"Care to explain 'Bones'?" /weird to say my own nickname.../
"Yes. An...advanced mind meld should solve the problem. It may become difficult to maintain since it will be the three of us verses the traditional two but it will achieve its purpose."
"Um what does this mind meld consist of? Like how will it help? Why is it 'traditionally' only two people?"
McCoy's face seemed to turn a little red but Spock continued "the mind meld I am suggesting would give us the ability to speak to one another within our minds. Thus being able to answer any questions we may have. We will also be able to feel each other's emotions and see each other's thoughts." The other two beings in the room gasped.
/this might get a little embarrassing.../ thought Kirk
/oh shit.../ thought McCoy
Spock continued "It is also traditionally only two minds because it is so...intimate...the link will essentially make us bonded." Spock said it so calmly it was like he thought this was a completely normal everyday experience!
"Intimate!?" /oh no! They'll find out I love them then kill me!/
"Bonded!?" /I can't marry them!...can I?...what would that be like to be married and love my two best friends?.../
"Affirmative...If you do not wished to remain connected once we are back in our own bodies we may…sever the link..." Spock sounded depressed at the idea this gave both McCoy and Kirk hope that maybe they weren't going crazy and could make this work...if only one of them could get the balls to spill first!

"I'm all for this meld thingy Spock I just have one question, well for now at least, if we do this and can see each other's thoughts wont that get, I don't know annoying? Stressful? Invasive? I mean Dr. McCoy and I as humans are thinking about random stuff constantly and I know you can think about 10 things at once and not even bat an eye! It won't ge-"
Spock cut him off before he could continue on his rant " No Captain you misunderstand me. We cannot read each others thoughts in the sense that I can see the exact conversation. For example Dr. McCoy and yourself will be able to 'sense' that I am contemplating something but you will not be able to ascertain if I am questioning what it is I would prefer to eat or questioning whether or not the new warp drive Scotty installed will blow up the Enterprise." Kirk chose to ignore that last comment for now.
"So essentially we can feel the 'emotion' connected to whatever it is you are thinking. So if I'm thinking about a patient's death you will know I am sad but not why?"
"Correct Doctor."
"Ok I think I can handle this. What about you Jim?"
"Sounds fine to me. One more question though; how will McCoy and I be able to communicate? We aren't telepaths."
"With my own mind linking the three of us you and McCoy will have the same access to each other. We will all hear everything we say to one another in our minds. The only way you two will not be able to communicate telepathically is if I somehow block the link or if I am killed; thus destroying all our links."
McCoy and Kirk gasped at this. The thought of Spock dying...it didn't settle well with either of them.
"Ok so no one dies. Check." Kirk said sarcastically...which looked rather hilarious on the Vulcan face. "Let's get this started, what do we do Spock?"
"If you will both join me on the floor." They all sat down Indian style on the floor in a triangle "If you could each move forward enough so that our knees are touching. Then Doctor if you could place your left thumb above Jim's right eyebrow left index finger at his temple and middle finger just slightly below the cheekbone." McCoy complied albeit nervously. "Perfect Doctor. Now if you could do the same with your right hand to my left." As soon as McCoy's hand touched Spock's face he felt the thrumming of energy. It shocked him so that he almost drew back. /...interesting.../ Bones thought.
"Jim if you could do the same to the Doctor and myself." Jim complied and felt the thrumming as well. /Wow I wonder if that's just how Spock feels or if it's all the telekinetic power.../
"Now I will do the same to you both. Once I do though no matter what you feel do not let go. Removing your hands too early could shatter the link and possibly cause damage to all involved. Once I create the bond in us all I will recede first thus allowing you to follow."
Before either man knew it Spock's hands were on their PSI points creating the meld; bursts of emotions and colors streaming through their vision. It was a rush of nothing put pure amazement bliss peace and love. Both men felt as if they were floating in a dream and just as they both wished the feeling would never end it stopped all too suddenly. The rush was gone but the feeling of each others being was still there in their minds.
They opened their eyes waiting to see if they could feel something different; proof that it really worked. Kirk broke the sudden silence "Did it work?"
≈ Of course ≈ thought Spock into both their minds.
Both men jumped heads shooting towards Spock, well McCoy's, body so fast they might have whiplash in the morning.
≈ Holly fuck! ≈ was McCoy's first thought
≈Doctor if you could please sensor your language it would be greatly appreciated.≈ Spock deadpanned in their minds. The next sound was one of the most beautiful Spock or Bones had ever heard. It was Jim's laughter rolling threw their minds. It created a beautiful image of bursting firework like colors to appear in their minds. This caused them both to smile...if only for a moment
≈You two are impossible≈
Spock wanted to enjoy the moment for as long as possible but he was exhausted from the mind melds and his new human form tired more easily than his own.
"You will forgive me gentlemen but I believe it is time to rest. I believe you would say Doctor 'I need to rest these old bones.'" Spock drawled in his new found accent. He really was having, dare he say it? Fun faking the Doctors southern burr.
"For once I agree with you hobgo- Spock. Now both of you out of MY quarters!" McCoy laughed. Kirk grunge-idly got up and left along with Spock. It was going to be one long night...and an even longer day tomorrow...

The long night started the moment they got to their bodies rooms. Spock wasn't sure how happy Doctor McCoy would be if Spock undressed his body but then again he wouldn't be too happy if he wore the same filthy clothes again. Thru the bond he could feel Jim and Bones become nervous as well as indecisive.../ presumably they are thinking the same thing/ Spock decided to be the bigger person and spoke to their minds first.
≈Jim, Doctor I recommend we vow to care for each other's bodies with the utmost respect since I see we are all a bit nervous on how to proceed...≈
≈Jesus Spock scare the living daylight's outta me!...but yes I agree.≈
≈Ok so no getting handsy with each other's bodies. Deal.≈
A few minutes later after they had all blushingly undressed their bodies and re-clothed them in their appropriate night ware they each settled into bed; the humans praying their dreams would not get over the top and the half Vulcan anticipating the onslaught of emotions that he was sure would come.
