Stein x Death the Kid x (M/F) Reader (Lemon)

Part 2 (Lemon)

 You had no idea how long you had been out for, all you knew was that when you woke up you weren't in the Academy anymore, the room was too dark and the walls from what you could make out were too dark if you compared them to the Academy's walls.
You tried to move your hands and feet but were shocked when you found them bound on what you now realised was a cold, hard table.
Thankfully some of your energy was back and if you were careful with how you used it, you might be able to remove the binds. However before you could even think of escaping, you heard muffled voices coming from the other side of the door (wherever that was, the room was too dark to make anything out clearly). There was a loud bang followed by...was that a moan? Oh no you could feel the lust from the people on the other side of the door, even with the lack of sight you could imagine a bright pink/red 'thread floating between the two people
Another moan was heard followed by a muffled voice "oh..." you were pretty certain that they just said their lover's name.
"Now, now Kid, we don't want to scare our guest yet do we?"
Your eyes widened and you couldn't stop your mouth widening in shock, Kid was dating Stein? When did that happen? Although now that you thought about it, those two were so good at hiding their emotions that even your ability had a hard time trying to determine what they were thinking about.
"I see you are awake" you tried to move your head only to discover that it wouldn't move, your body was even more restrained than before.
You blinked and shut your eyes tight as a bright light was enveloped in front of your face, it was too bright for your sensitive eyes.
There was a deep chuckle "you can open your eyes now (y/n), the light has been dimmed" you open your eyes and were greeted by none other than Stein "you okay? You passed out in class after using that strong attack and have been out for two days" he continued to explain.
"Why am I tied up?" Was the first thing that came out of your mouth.
"For safety reasons" you almost snorted.
"Let me go"
"I don't know, what makes me think you won't escape when I do? Or should I dissect you right now? I would love to see what makes people think you are so special" his fingers trailed down your cheek which made you shiver at the contact, sheesh even his hands were cold.
You mentally sighed, as much as you wanted to leave, you knew that it would take only a matter of seconds for him to catch up to you, besides this may be the only chance you had as to what they saw in each other, you would never tell anyone or course, you cared for them too much to see them get into trouble.
"I promise Stein that I will not leave this room unless you let me, although if you still don't trust me you are welcome to bind my hands in metal so I won't burn them off" perhaps that would help.
You could practically feel the smirk appear on the doctor's face "I think I will save the bondage for another time, when you have more 'juice'" he chuckled creepily when you blushed like a tomato.
You watched silently as Stein removed the bindings on the legs first before moving to the hands, you tried to move but still couldn't move your limbs, you sighed when you realised that Stein had used that soul-stitch thing.
"What about the soul binds you've placed on me?"
"I think you look better with them on, all tied up with you at my mercy, Kid would love this as well" you did not expect him to lean down and trail kisses down your cheek and forehead, or the emotions he was feeling at the moment.
"Why are you with him? Or are you using him?" maybe accusing him would keep him distracted.
"I don't use him, he came to me willingly, he needed someone to comfort him after his...attack" he said after he removed his lips from you.
"What attack are you talking about?"
"You mean he never told you?" his voice clearly said he knew that Kid never told you, or even the others for that matter.
"Kid had been, mentally and physically abused on one of his missions, I found him after he had returned, he was hiding in one of the abandoned classrooms crying his eyes out, he had never looked so helpless before" there was a glint of madness on his face before he reigned it in quickly "I helped him, I put him back together, we soon started dating afterward"
"Why are you telling me this, I mean why did you tell me what happened to Kid when he clearly didn't want me and the others to know?"
"They do know (y/n)" came a voice.
Stein removed the soul binds and you didn't hesitate to lift yourself up so you have a proper look at Kid, who was surprisingly out of his usual suit and in some casual wear.
"Can you give us a moment Stein?" Kid never took his eyes off you as he asked.
Stein didn't say anything; he just walked over to Kid, placed a hand on his shoulder and placed a kiss on his head before leaving the room, closing the door slightly as he did so.
The air was slightly tense from Kid's statement "why?" your voice sounded like one who had been betrayed, Kid flinched as well.
"They weren't meant to know, but somehow they did, I begged them not to tell you because I was afraid of how you would react and see how disgusting I was afterward" Kid looked down in shame "I didn't want you to see me as some asymmetrical garbage"
You resisted the urge to smack him on the cheek, after all you had a bad history of being abused, was it any different from Kid's? No, you patted the space next to you, making Kid look at you with caution and surprise before doing as you suggested, he was surprised when you wrapped an arm around his back like a half hug.
"Before I moved here, to Death City" you started "I had a family, but at the same time I didn't, my mum and dad were meister and weapon, when they found out I had magic as well as their abilities they became cold and hated me, everything I did was wrong in their eyes, they acted as if I was about to kill them or someone when I left the house, I was forced to clean the house with my hands, I was called witch, brat, failure and a bunch of other names that were far worse than those, my dad would beat me and mum would starve me, as if those would take the magic out of me" you didn't realise you had your head down while fiddling with your hands "I tried to make friends secretly but eventually my mum and dad found out and because they were popular with the town" you took a shuddering breath, not knowing that Kid was now the one comforting you "they convinced everyone that I was a witch and to be killed on sight" you couldn't stop the tears escaping as you relived that horrible memory, the sight of your parents looking at you with disgust as well as the town, the twisted delight and sickening grins on their faces when they were able to get you out of that forsaken town and ending up on the outskirts of Death City without even knowing how you got there in the first place, a weak and broken soul.
"Do you feel better now?" You looked up in shock to see Stein on the opposite side to Kid but he didn't have an arm around you "would you like me to fix you too (y/n), would you like me to put you back together again?"
His eyes pierced yours as if he was looking at your soul this very moment, you could not sense any kind of deception but still "why me?"
"Kid fancies you" Stein stated "but he still loves me so he let you go because he thought you only saw him as a friend, as for me I wasn't lying when I thought you were special" he leaned just a breath away "what I wouldn't give to dissect you and see how you tick"
"Okay knock it off Stein" Kid pushed him back slightly, then to your surprise (again) he sat in Stein's lap with no hesitation, then he looked at you "I love you not just for your symmetry, but because your soul seems to sync with ours, you are what kept me and Stein sane when we had been influenced by the madness" oh yeah, you had been found two months before the final showdown with the Kishin, Stein and Kid had been seriously injured and got a full blast of the madness, your magic somehow managed to not only heal them but remove some of the madness, which was technically impossible, even according to Lord Death.
"Fix me" you looked at them both with desperation in your eyes, your hands took each of their hands and gripped them "put me back together, make me forget my old life and give me a new one, heal me, use me, whatever makes you happy"
Kid didn't hesitate to pull you close and kiss you lightly on the lips, this was your first kiss and already you could feel yourself melting into the feeling, the emotions coming from them both were joy, love and a whole lot of lust coming from Stein that made you feel weak at the knees.
"I will never use you (y/n)" Kid looked at you with such a fierce gaze before it slowly melted away into a smile that took your breath away "I am going to make sure that you are so cared for you will never want to leave us" he then looked at Stein "I think the table is a little too hard for a first time don't you think?"
Stein didn't say anything, he just got up, nearly knocking Kid over in the process and then picked you up bride style and walking at a fast pace to where you could only think as Steins bedroom. Sure enough he opened up a door and before you could even look properly you were deposited on the bed (you bounced on it a few times) then had a whole body of Stein on top of you while proceeding to give you the best make out session in your life.
"Finally" he breathed before he began to devour your neck "you are going to have the best night of your life little one, I am going to fill you so much you won't be able to sit down for a week"
"Don't leave me out of this" Kid interrupted as he got on the bed as well "it has to be perfect, we don't want to scare (him/her) now do we?" you could tell he was quoting from earlier, you think, it was hard when you still had a mouth on your neck and trying to mark you from what you could tell.
"Alright then Kid, why don't you continue where I left off while I get something" he got off the bed before Kid could say anything.
Kid looked at you for a moment "do you want us to go all the way?" he asked uncertainly.
"I would have said something by now if I didn't want it" you replied "besides it's not like I have a choice in this"
You were shocked when Kid moved into the same position as Stein did "if you don't want this say it now because when Stein comes in here there will be no going back, once he and I mark you properly you will be his and mine forever"
You only needed a few seconds to think before pushing your lower body towards Kid, earning yourself a moan and pant for your efforts "show me Kid, make love to me with Stein and so hard that I won't be able to walk properly without thinking of how it happened"
"Oh (y/n)" Kid kissed you with deep passion before he slowly removed your clothes (your shoes had already been removed) and leaving you only in your underwear, perfect. Looking at where Stein had left a hickey he carefully measured where the other one should be on the other side of your neck before using his mouth.
You were now panting heavily and tilted your head back, geez they only touched your neck with their mouths and already you were panting for them.
"I see you've got (him/her) ready" you couldn't make out that voice properly "now move so we can begin the experiment"
That got you out of your daze and pushed Kid off of you and tried to move as far away from them as you could, 'experiment' you cursed yourself for giving in so easily, was this all they wanted, use you then toss you away when they were done? Blast you were about to get a panic attack.
"Nice one Stein" Kid growled before turning towards you, holding onto your arms tight enough that you felt his presence "(y/n)" he started softly "you know how Stein has a problem with emotions, he hides them to keep his madness at bay, he is still learning on how to express his feelings, when he feels like it anyway"
The emotions they were both emitting were enough to get through to you and eventually calmed down.
"Interesting" Stein mumbled then began to express another emotion, lust.
Oh no, he found out, how? Oh wait it's Stein, when an interesting experiment/puzzle comes along he will do whatever it takes to complete it. You began panting as the lust washed over you, causing you to rub along Kid's leg.
"What's gotten into you?" he said.
"(He/She) can feel our emotions, when we express them strong enough (he/she) will feel what we feel" Stein explained in his usual tone.
"Stop it then Stein because that is basically rape if they are not their own" Kid snapped.
Stein pouted slightly but did as Kid said.
However you stopped for only a few seconds before pushing Kid backwards and getting on top of him and doing what he had done to you a few minutes ago, you didn't care anymore, if this was going to be a one time opportunity then you were going to take it, just this once you were going to be selfish and take whatever you could get.
"Less talking more stripping" you mumbled as you tried to remove Kid's shirt, nearly ripping the buttons out and not caring that Kid would flip over them.
"Stein a little help?" Kid called out weakly as he tried to remove your arms.
Stein was there in an instant and pushed you down on the bed and used his soul thread technique, you lay there panting and trying to move with little success.
"Please" you begged "use me, carve me, do whatever you want with me please I want to feel needed"
"I think I expressed myself a little too much" Stein mumbled to himself before grinning his usual smirk "now just relax (y/n), we are going to take care of you" he turned to murmur something in Kid's ear then turned to give you a kiss while using a scalpel he got from who knows where to remove your underwear.
"You ruined my favorite shirt little one" a dark look could be seen on Kid's face "you are going to be punished"
Stein removed his stitch technique just as Kid began kissing your stomach and carefully going downwards, what he did next made you nearly scream in delight, Stein almost had to gag you to keep quiet, it would be rude if someone walked in on them now wouldn't it? You could feel yourself reaching your climax, Kid seemed to notice it as well as he immediately stopped what he was doing earning himself a whine for not continuing.
"Soon little one" Kid murmured before getting off the bed and proceeded to remove his trousers and boxers and carrying on where Stein left off as he too proceeded to remove his own clothes.
Once you were all naked Stein moved behind Kid and began prepping him as Kid did the same with you, both couldn't wait long and they didn't think they could handle teasing you for long either, once they were sure the other was prepared they quickly placed a condom on their members and carefully inserted themselves, making three become one. The emotions you were all emitting were too much for you, and the fullness of Kid's member forced you to grab him into a hug, one hand on his shoulder and the other in Stein's hair. The room was full of pants, groans and plees as you all tried to pleasure the other person, but it wasn't long till everyone climaxed, pulling out carefully so as not to hurt the one they were penetrating you collapsed on the bed, Stein and Kid looked at you as you had already fallen asleep, most likely from the emotions as well as physical feelings, no matter, you were theirs now and they were not going to let you go.

You woke up the next morning feeling like you had just gotten a hangover (as close to one since you don't drink), where were you? What happened? You couldn't remember anything last night, you tried to move but something was stopping you around your waist, you looked down and saw that it was a pair of arms...and one of them had stitches on them.
You gulped as you craned your neck slightly, only to come face to face with a screw in grey hair, oh sh...
"I see your awake" he mumbled between your shoulder blades, sleep still showing in his voice.
He removed his arms before proceeding to move on his back and stretch as far as he could, you caught a glimpse of his (six pack, nose bleeding) chest before quickly looking away, not wanting to look further down.
He noticed your stiff form from his limited eye sight "you okay? Sorry if me and Kid went a little ruff last night" his mouth turned into a half smile before it turned into a frown "you don't regret it do you?"
"What happened last night? Why am I..." you trailed off before all the memories came washed over you like a hurricane and made you blush like a rose as you tried to stop the tears from escaping, after all this was most likely a one night stand and while you wanted to save your innocence for 'the' one, you wouldn't trade it for anything.
"I'm guessing with everything that happened last night you must have forgotten for a moment, oh well" you were surprised when he pressed himself close to you again "it's just you and me for the entire afternoon, Kid had to leave so Liz and Patty wouldn't get too suspicious, he left a gift for when you woke up but that will have to wait till later"
Before you knew it he flipped so you were facing him and looking up before proceeding to enter your still sensitive but (still) loose entrance, at first you thought he was going to be rough with you, but he didn't, he leaned in close so that your breaths mingled with each other and both of his hands were entwined with yours, his movements were slow and sharp and the room was once again filled with your breaths and moans, you didn't know how but you managed to keep your eyes trained on his the entire time like he was trying to show you something, and then it hit you, because of his madness he was unable to feel things the way everyone one else did, this was the only way that he could show it, if that wasn't proof enough the 'thread' between you and him was a pink red, love and lust were what you were feeling and it was enough to send you both over the edge.
"We've both claimed you" he mumbled into your neck from where he half laid on top of you "unless you say it we will never let you go"
You were gasping as you lay a hand in his hair, when you got your breath you mumbled "never my sadistic lover"
That earned you a chuckle and a kiss on the neck before you both moved into a more comfortable position, looking to your right you could slightly make out a single red rose, definitely Kid. You would make sure to thank him later, but right now you were content to spend a while longer with your second lover, but it didn't feel the same without Kid.
Kid silently made his way into Steins house and made straight for the bedroom, he was greeted by (y/n) and Stein cuddled up together both looking slightly uncomfortable, quickly stripping he got into bed so that you were lodged in-between them, no one was there to see the faint smiles on all their faces as they felt each others presence. It would be difficult hiding this from everyone, but in the end, it would be worth it.
