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

Part 1

You had been at the DWMA for at least a year now and in that time you had gotten close to Maka, Soul, Death the Kid (Kid for short), Liz and Patty the sisters, Black Star and Tsubaki.

You were a weapon but didn't really need a meister, you also had a few magical powers like Blair the cat but stronger and completely random and were mostly related to the elements (fire, water, air, earth), they really did come in handy during the lessons as they were the closest thing to actually encountering a witch, while they weren't as strong as an actual witch's, Stein still insisted that you use them when you weren't all dissecting animals. But there was one thing you had never told anyone, not even Lord Death himself, while you could see the souls like Stein did you were also able to sense the emotions they were admitting at that very moment as well as the person the emotion was for, so if Maka was smiling at you when you met her at the entrance of the school before going in you were able to feel the genuine happiness and see a yellow 'thread' between you and her, it also told you that she wasn't faking it, like some other people. The only downside was feeling what they were feeling and you would feel overwhelmed by the amount of emotions people were feeling and showing to each other.

You usually went into class early in the morning and after break to practice and strengthen your mental walls to stop the emotions overwhelming you, but no matter how hard you tried they never seemed to get to the scale you wanted them to be, not to mention it was one of the only times where you had peace and quiet for yourself, you also used it to practice your magic but Stein loved to forget that little tidbit every morning.
"May I ask why you are still in class a few minutes before you are supposed to? And practicing your magic?" speak of the Kishin.
You didn't look up since you clearly heard the motion of wheels before he even spoke "well unless you are planning dissection for the afternoon I would like the extra time to practice my magic, plus we have this conversation every day, why do you pretend to forget them when clearly you have a bigger brain? (whats left of it anyway) Or is it mostly stored up with methods on how you want to dissect us?" you asked rhetorically but you had also finally lost patience.
A creepy smile appeared on Stein's face, the only thing it did was make your spine tingle "I love it when I get you riled up" he said quietly.
"What was that?" you raised an eyebrow.
"I said yes we will be practicing today so if you need the entire floor to practice until breaks over then be my guest"
"Don't let the door step hit you on the way out"
Not a second later his chair hit the step and fell flat on his back, you sighed and went to get him up, you were the only student that actually had the guts to get close to him. As Stein got up from the floor he didn't notice you pick the chair up and push it behind him and take him by surprise.
"OOF!" you didn't see his surprised face as you were already pushing him down the corridor with all you strength.
"HAVE FUN!" you shouted with joy before walking back into the class room and began to your music, break wouldn't finish for another ten minutes so you could to two songs while practicing.
Unfortunately that wasn't going to happen as you felt a presence so you had to turn it off "what did you do this time (y/n)?"
You turned round to see Kid looking at you with that usual bored look, but you could have sworn there was a hint of amusement in his small smile, you removed your headphones before speaking.
"Professor Stein was once again pretending he knew nothing of my early 's and being sadistic, although I don't think that counts since he's always sadistic" you giggled.
Kid chuckled slightly, but for a moment you could have sworn he blushed lightly "oh I'm sure it was nothing you couldn't handle"
"I think I'm the only one who can handle him and be in the same room without freaking out" you chuckled.
"Just out of curiosity" Kid said after chuckling with you "what exactly did you do?"
You had a mischief smile appear before telling Kid what before he came in.
You could clearly see Kid was trying not to laugh as his mouth muscles were twitching like crazy, it took a while before he was able to pull himself together "I kind of overheard what we were going to be doing for , would you like some practice with me?" if you didn't know any better you would have thought he was asking in a shy behavior, but he couldn't detect any emotion coming from him.
"What about your weapons?"
"I kind of need to brush up on my physical defense, just because I'm son of Lord Death doesn't mean I should slack off"
"I thought your fighting came by instinct" you said with pure interest.
"In a way yes but I still need practicing just like everyone else"
You smiled politely "well in that case" you shot a small fireball his way, he jumped out of the way just in time.
"No fair" he complained as he got into battle stance.
"Your enemy will attack without warning" was all you said before throwing another fireball in his direction but he easily dodged it that time.
You both spent the next ten minutes sparing against each other, but you made sure not to use your magic too much since you were going to need it for lesson, you mostly used your weapon form when he got too close.
When you both finished there was seconds before the bell went so you both sat down next to each other, Kid then asked you "how come you didn't use your magic much? And when you did how come it didn't hurt?"
"I'm saving up the energy for next lesson, you know what Steins like when we fight, all out or we fail immediately"
"I'm glad you think so highly of me (y/n)" came a voice.
You groan and slammed your head against the table "speak of the Kishin" you said to the table, you weren't sure if Kid heard you and if he did he didn't comment.
"I'd like to speak with you after class (y/n), now if you are all ready we will be fighting with magic, I hope you haven't used up all your energy yet (y/n)"
"No sir, I haven't, I have plenty of magic juice left for the entire lesson" you replied, looking at Stein straight in the eye with no hesitation.
Kid choked next to you and blushed like a rose, then you saw a red 'thread' between him to yourself, for a moment you felt a rush of lust between you both, but it was so fast you were unable to decipher it properly.
"Thank you for that dramatic sentence, are you coming down here or not?"
As you moved back to the middle of the room you could of sworn you saw another red 'thread' between you and Stein, but that was impossible...right? There was no emotion coming from it so you passed it off as your imagination.
"Since you and Kid have been training during break would you like to give us a demonstration but with more violence?" he said as he turned his screw "your welcome to use your weapons if you prefer Kid"
You could tell Kid was trying not to groan as you could clearly see his jaw tense, wait a minute, why was there a blue line between him and Stein? Embarrassment? Why was that there?
"On second thought, I'll do it, I'm interested in what you've learnt from your little sparring match"
Was he serious? He'd beat you within seconds.
Before you knew what was happening you were thrown back by a punch in the stomach, Stein moved for another punch but you quickly dodged it
"WOAH!" you barely had time again to dodge another attack, you threw a water ball at him, making him look like some cat that had fallen into a bath of water.
Stein didn't seem put off, but that didn't stop you from throwing a small lightning bolt at him, shocking him but not enough to barbecue him.
Surprisingly Stein fell to the floor but didn't stay down for long "is that all you got?" he grunted deeply as he got up, you noticed his hand crackle slightly, blast it was his soul wave length.
You dodged him as he pushed his hand out to shock you, you were inches away from nearly getting electrocuted because you knew he would hit you so hard you would past out.
"OOF!" curse it you weren't paying attention, he shocked you in the back causing you to fly straight into the opposite wall, you were going to get a headache after this.
"Focus" Stein said in that stupid tone.
"I'm doing so you sadistic psychopath" you gritted before turning around so quickly while throwing a strong earth ball that Stein never saw it coming.
Stein was barely able to dodge it, the ball only grazed his side and shoulder, but what Stein said next made you freeze "come on mousy are you afraid of being to be my chew toy? Or should I dissect you right now?"
You jerked to a halt, your eye twitched really badly but you never heard the gasps coming from the students, if there was one thing you hated the most, it was being someone's plaything let alone a dead body for autopsy.
Before anyone could blink you threw a fire ball at him, then a water ball, then a gust of wind knocking him into the wall behind him, before he could so much as move you threw another earth blast at him in the stomach causing him to grunt and double over.
"Come on (y/n), is that the best you can do?" he grunted as he got up on his feet, looking as if you hadn't just blasted him with the four elements.
"I saved the best for last" you panted, this would be your last shot since those last attacks were more effective than when you fought Kid and drained you more faster.
"Well then? Lets see it" Stein taunted.
You clapped your hands together and thought of all the elements under your control and how they would look like when wrapped around each other "SOUL RESONANCE! ELEMENTAL STRIKE!"
You held your arm back as if to throw a ball, in your (d/h) was a ball of all the elements held together as if by some elastic bands and threw it as hard as you could at Stein, the last thing you saw was a blast before everything went black.
