Quick Author's note: Im using the training parts of this story to just have an amusing side to all of this with all the flirting and all that, once the real action starts, it's about to get SERIOUS. Well I hope you guys enjoy the read.

It's now the year 850, it was a rainy day, but a little rain never hurt anybody right? Especially not the 104th cadet corps.

Y/N: LET'S GO LADIES! YOU ALL DON'T STOP RUNNING TIL I DROP TO THE GROUND AND I'LL TELL YOU NOW, I'M NO WHERE NEAR TIRED! MOVE YOUR ASSES!

You were running a ten mile gear run through the forest and led them on a thick mud trail. You saw armin was lacking, and falling behind.

Y/N: ARLERT! PICK UP THE PACE, AT THAT RATE YOU WOULD'VE BEEN EATEN AT THE THIRD MILE AND WE'RE BARELY ON THE SEVENTH! MOVE YOUR ASS!

He was panting hard trying to gasp for air, what surprised you was that reiner fell behind to grab his pack to lighten armin's load.

Reiner: C'mon, give it to me.

Reiner lugs it onto his back and starts carrying his and armin's gear.

Reiner: We're being graded on this exercise, so we gotta pick up the pace or we all fail.

Armin: But if you help, they'll take points off you.

Reiner: Better not let them find out then huh?

As they spoke, you were taking mental notes of those who were candidates for being in the top ten of the class.

Y/N Thoughts: Reiner Braun- Strong soldier in both body and mind, and is trusted by all other recruits.

Out of no where armin found his second wind and started sprinting and grabbed his bag from reiner, pulling ahead to the middle of the group.

Y/N Thoughts: Armin Arlert- Though he does lack in physical traits, his intellectual skills with the ODM gear and tactical planning have proven him a great asset as a soldier.

Timeskip 1 hour:

Y/N POV:

Back in the forest, you and Shadis are observing them with the ODM gear against the titan dummy's. You see Annie, Bertolt, and Jean all heading for the same titan dummy and slice the nape.

Y/N thoughts: Annie Leonhart- Her strikes are practically targeted perfectly, but lacks any real intent on working with others, and tends to keep to herself...Bertolt Hoover- Has quite the potential as a soldier, but does not have any initiative...Jean "Horse-Face" Kirstein- His has quite the talent with the ODM gear, but his personality can cause friction between him and other comrades.

Jumping to another branch, you and Shadis spot Connie and Sasha right on Jean's tail and hear Connie yell out.

Connie: Thanks Jean! I knew following you was a good idea!

As he was about to slice the nape, Sasha had already beat him to the target.

Sasha: YAHOOO!!!!!!!!!!!!!!!!!!!!!

Y/N Thoughts: Sasha Blause- Her unique instincts make her good, but that also makes her unsuitable to work well with the others... Connie Springer- He presents very good physical attributes, but is also susceptible to being quite dim witted.

Jumping to another branch you spot eren and mikasa heading for two dummy's. You see mikasa slice with precision, cutting the nape off clean, while eren is a little under her depth.

Y/N Thoughts: Mikasa Ackerman- Mastered all subjects of the cadet corps, and amongst the recruits and even some officers, she is considered a one of a kind, being one of humanity's greatest soldiers...Eren Jaeger- There isn't anything too special about him, except for the fact that he has worked harder than anyone to improve himself and become a better soldier than he thinks he is...and he is the most motivated in reaching his goal than any other recruit here.

Shadis: Alright corporal blow the whistle and bring them in, it's time to begin hand to hand training.

Y/N: Yes sir.

You blow the whistle and everyone lands on the branch below you and looks up towards you and Shadis.

Y/N: Alright, that completes the ODM training, now head back to camp and get that gear off and head to the open field near the mess hall, we will be working on hand to hand combat. Move out!

Recruits: Yes sir!

You watch as they take off towards the camp.

Keith: They've grwon quite a bit haven't they?

Y/N: Yeah, we really whipped them into shape huh?

Keith: Your father would be proud Y/N.

Y/N: I already know he is, and I'm still proud of him.

Keith: Your no longer that stubborn brat from before you know? You've become quite the man.

Y/N: And you've become quite old sir, haha.

You chuckle as he smirks at your comment.

Keith: Don't think I won't drop you off this branch corporal.

Y/N: I was just kidding commander.. Thank you sir, for everything you've taught me.

You hold out your hand towards him and he grasps it firmly.

Keith: It was an honor Corporal L/N.

Y/N: Just as I felt Commander Shadis.

With that said, you both take off and get your gear off and head towards the field to see all the cadets standing around talking among themselves.

Y/N: Alright line up cadets!

Recruits: Yes sir!

Shadis: Now you will be sparring with one another, one person will have a wooden dagger and the other will try to disarm the attacker. I will be in my office so in the mean time, Corporal L/N will be in chare. Follow his orders as they are mine. Fall out!

Recruits: Yes sir!

They all pair up and start to spar with one another as Shadis walks away. You watch carefully seeing how much each recruit has improved and you have to admit, the difference is night and day. These worthless un-trained people, are now well-trained titan killing machines. Out of the corner of your eye you see krista sparring with mikasa and she seems to be struggling while mikasa dodges with ease. Deciding to do your job you walk over slowly to them, but while heading towards them, you find a way you can tease Krista a bit and smirk.

Y/N: Having trouble cadet Lenz?

Krista: A-alittle sir..

You walk behind her and wrap places your hands on hers, wrapping your arms around hers like their your own and you control her movements. She blushes slightly and on the inside is screaming with joy, while mikasa is well..giving off a dark aura..

Y/N: A good tip to learn, wait til you see an opening for an attack. Always keep a tight grip as well. 

You press your bodies closer and lean to her ear, and whisper.

Y/N: Wouldn't want to lose your grip would you? Damn things can just..."slip"..out of your hands~

She shudders and closes her eyes imagining the things she would do with you.

Krista's Wet Daydream POV:

Y/N: Krista, follow me please, I'll teach you more in..private~

Krista: Lead the way corporal~

As we walk I turn back around and wink at the four girls who tried taking my Y/N. We go around the back of the barracks and no one is in sight. Then all of a sudden corporal Y/N pins me to the wall with my arms above my head and starts to kiss me passionately.

Krista:Mmmm~ Corporal~ ahhh~

I start to squirm around as he kisses my neck.

Y/N: Mmmmm, krista, your sooo good~

Krista: Please corporal, I've disobeyed your order, give me my punishment~

Y/N: You've been a bad soldier huh~ Mmmm~

Krista: Ahhh~ Yes~ Punish me~

Back to reality:

I'm snapped out of my wet day dream by a hand waving in my face to see it was the corporal.

Y/N: Cadet Lenz? You there?

Krista: S-sorry sir! I spaced out.

Y/N: Your drooling cadet.

I feel the side of my cheek and notice it is wet. I blush in embarrassment.

Y/N: Haha, alright ackerman, your turn.

Mikasa's POV:

Oh my god yes! Now's my chance, if I can get him somewhere private, I can make my move, and he'll be mine.

Mikasa: Corporal, can we go somewhere?

Y/N: And why is that?

Mikasa: Because I don't feel comfortable ummm..*whispers* learning when I'm already known to be already the best, I'm a bit self-conscious when I have to be taught something.

Y/N: If that makes you feel more comfortable, I don't see a problem.

Mikasa's thoughts: Yes! Now I ju-

Krista: Sir?

Y/N: Yes cadet?

Krista: Annie is walking around doing nothing.

She points to annie who is just walking around.

Mikasa's thoughts: Why you little..this was my chance and you took it!

Y/N POV:

After seeing leonhart just slacking around you bid the two a farewell and yell outloud.

Y/N: LEONHART!!

Everyone stops to look at you.

Y/N: Front and center cadet!

She rushes over and stands at attention with an emotionless face.

Annie: Yes sir?

Y/N: Since you feel that this is a waste of time...

You take a wooden dagger from a cadet.

Y/N:..you will spar me.

You both take a fighting stance as everyone watches in suspense. There was a slight breeze blowing, and as the wind died down, you rushed towards annie at an incredible speed that you leave a gust of wind blowing behind you, not expecting this she's barely able to dodge your attack. After dodging she attempts to kick you in the head, you duck under and grab annie's leg and sweep her other leg dropping her to the ground. Just as she lands, you mount her and hold the wooden dagger to her throat and lean in close.

Y/N: You kicked high knowing I would do this didn't you?

She smirks and puts her hand on your head, stroking your (H/C) hair.

Annie: You should discipline me corporal, I've been..

She puts her hand on your member, Krista, Mikasa, Mina and Sasha see this and are infuriated.

Annie: A bad soldier~

Y/N: You are stubborn aren't you?

Annie: Only when your around~

You look up and notice eren and reiner just stadning around, you lean to her ear and whisper.

Y/N: If you go over there and drop eren and reiner on their asses, I might give you...

You put one hand on her thigh.

Y/N:...a reward~

Everyone around you turns beat red seeing the position your in but don't see where your hands are, you get up with a smirk and annie has one as well as she gets up.

Y/N: What are you all standing around for? You wanna do another 10 mile run?!

Everyone scatters and starts sparring again in fear of another run. You see annie challenge eren and reiner, then smirk knowing the outcome. You watch as eren charges at annie with the dagger, but takes a kick to the shin and falls down holding his leg. He gets up and charges again only to be swept and land on his back, legs above his head. She hands reiner the dagger and it looks like he's about to shit bricks. He takes a deep breathe and charges at annie, a second later he's in the same position eren is in. Annie walks towards you saying her hips, smirking.

Annie: So what's my reward?~

She puts a finger on your chest moving it slowly up and down.

Y/N: What do you want?~

Annie: I have something in mind, since it is my reward, you have to follow me and I'll be giving the orders this time~

Y/N:I suppose that I-

Guard: Corporal!

You turn your head to see a guard running towards you with a document of some sort in his hand.

Y/N: What is soldier?

Guard: Just received a letter, it's from your sister sir.

Y/N: Give it here and return to your post, thank you.

Guard: Yes sir!

He runs off out of sight.

Y/N: Alright cadets, training is over, head to the mess hall for some chow.

Recruits: Yes sir!

Annie: But s-sir, what about my reward?

Y/N: Sorry leonhart, I have business to attend to. You'll receive it after I'm done.

Annie: I better.

You walk to the officers quarters and into your room, you untie the document and roll it out then move a candle closer to you and read your sister's letter.

Hey little bro,

       It's been a while since I left you there at the camp. I miss you so much, I hope they didn't change you too much though because I would miss the crazy lovable brother that I adore and love so much. It's been crazy here in the scouts HQ, and guess what! I got placed into Captain Levi's squad! I know how much you loom up to him, so I started talking to him about you even though he wouldn't really say much, actually he doesn't really speak much, but what he does say, it makes me happy. He says that if you do join the scout, he would have you placed in his squad with me! He says that family should always be together to protect one another.
We're preparing for our expedition in a few days, which means I have to leave soon. I really wanna see you before I go, so Levi and the commander allowed me to spend time with you tomorrow! I'll be there tonight but we start tomorrow morning. I can't wait to see you again Y/N. Stay safe. I love you

Sarah

You get so excited you burst out the front door and head to the entrance of the camp. You sit on a bench waiting and it get darker outside. Eventually sleep overtakes you and you sit there snoring unaware that someone is watching you.

Sarah's POV:

I was preparing my bag for my trip down to the training camp to visit my little brother when the captain walked in.

Levi: Oi, I thought you left already?

Sarah: I just need to pack a few more things and I'll be off.

Levi: Hurry up, before I change my mind, also Petra is coming with you as well?

Sarah: Huh? What for?

Levi: To give me an evaluation of your brother. I can't just take only your word, I need another from my squad to confirm if he is capable of being part of this elite squad.

Sarah: Okay then, at least I won't be alone on the way.

Levi: She's outside waiting with two horses, get going.

Sarah: Yes sir.

I finish packing and head out of our living quarters and see Petra waiting by the gate with two horses and a bag of hers.

Sarah: Hey Petra!

Petra: Sarah! C'mon let get going, it's going to be dark soon.

Sarah: Right.

We hop on our horses and make our way to the training camp. Along the way me and petra make small talk here and there. Then she starts asking me about my little brother.

Petra: So what's your brother like?

Sarah: Y/N? Ohh well he's stubborn that's one thing for sure, but all around he's a good person. He's always the first one to jump in front of someone who's in danger, always the first to go and help people who need help, he doesn't give any regard to his own well being, and always looks out for everyone.

Petra: Wow, so he's quite a character huh? What does he look like?

Sarah: Explaining is too hard, you'll just have to see for yourself.

Petra: Hmph. Well I wanna know if he's cute at least.

Sarah: PETRA!

Petra: What?! I'm just kidding, I mean isn't he still younger than us?

Sarah: Yeah since me and you are both 24, he's still 19.

Petra: Well I guess I'll figure it out soon enough, and it got dark fast, good thing we're about here already, look.

I look ahead to see the entrance of the training camps, but also see someone on a bench in front as well. As I got off my horse and walked up to the person, I saw it was my brother asleep with the letter I wrote him in his hand. Awww, glad to know he still misses me. I whisper/yell at Petra to get off her horse and look at my brother.

Petra: What? Who's th-, whoa, who is this beautiful man?

Sarah: Petra! That's my little brother!

Petra: What?! That's Y/N?!

Sarah: Yes! That's Y/N! And DON'T get any idea's Petra!

Petra: Fine! But what are we gonna do? Just leave him here?

???: Or you could carry him to his bed.

Me and Petra squeak and turn around only to see Commander Shadis behind us.

Shadis: He's been waiting here for 3 hours, and slept for 2.

Sarah: He really waited for me that long?

Shadis: He blasted out of his door after he read your letter. Why don't you take him to his room, I'll have the guards put your belongings in the guests rooms you'' be staying in.

Sarah/Petra: Thank you sir.

Shadis: Now get him inside, he's starting to drool

Y/N: *Loud snore*

I giggled seeing the state my brother is in and pick him up and carry him to his quarters, but out of the corner of my eye, I swear I can see Petra eyeing my brother.

Petra's POV:

I kept looking at Sarah's little brother and look him up and down. I can't help but bite my lip and wonder what his body looks like, he looks in good shape, ugh I wanna rip his shirt off right now and see.

Petra's Thoughts: Oh my god, sarah's brother is so hot, what the hell?! I need to see his body...all of it...

I continue biting my lip and head towards my room, thinking about what I could be doing with Y/N. I enter the room, lock the door and lay on the bed imagining what I could be doing with Y/N.

Petra's wet daydream:

Petra: Oh Corporal Y/N~

Y/N: What is it Petra?

Petra: Can you assist me in helping me get out of my gear straps? I have a difficult time taking them off on my own.

Y/N: Of course I can Petra.

Petra: Follow me please.

I lead him to my room and as he walks in I lock the door and and lean against the door. He turns to me and smirks knowing what I did, and starts walking towards me and holds me by my shoulders against the doors.

Y/N: You didn't need help did you?~

Petra: Ohh I do need help though, but not with my belts~

Y/N: Then what do you need help with?~

He leans closer to the point where our lips are inches away, our breathes start to get heavy and I place my hand on his member and feel it grow in my hand through his pants, I shudder thinking of how it'll fit and whisper into his ear.

Petra: I need to get out of these pants~

Hearing this he smirks and pushes me harder against the door and starts to kiss me passionately while taking off my jacket and I unzips his pants and slide his jacket off. I pull away and lift his shirt off to reveal his well toned body with a set of rock hard abs. He rips open my shirt and throws it to the ground and picks me up and wraps my legs around his waist while he kisses my neck ,making me moan softly as he carries me to bed. He drops me on the bed and we both take off our clothes til were both just in our undergarments.I see his fully erect member bulging out of his pants and I start drooling.

Petra: Mmmm~ Please gimme~

Y/N: Umm petra?

Back in reality

Sarah: PETRA!

I'm shaken out of my wet dream and see Sarah next to my bed with her hands on my shoulders indicating she shook me to bring me back, darn it.

Petra: Huh? What happened?

Sarah: It's dinner time, Y/N's waiting for us to go with him.

Petra: Oh, sorry, I just dosed off.

Sarah: Umm, Petra?

Petra: Hmm?

Sarah: Your drooling.

I put my hand on my left cheek and feel a wet liquid coming from my mouth, wow, I must really want him.

Sarah: Well lets go, don't wanna keep Y/N waiting.

I nod and wipe the drool off and we head out with my soon to be boyfriend to go get dinner.

Y/N POV (20 minutes ago):

You woke up to see you were on your bed, how did you get here? You looked to your left and see someone looking around your room, you yawn and get their attention to see it's your sister.

Y/N: SARAH!

Sarah: Hey little bro!

You run up and hug your sister tight and she returns the hug giggling seeing that you still care about her like you did before.

Y/N: I got your letter, is it true?! Are you really in Captain Levi's Elite squad?!

Sarah: Yup! And I told him about you and he sent someone with me to do a personal check to see if your good enough to join as well.

Y/N: Well I won't let him down. I've been constantly training just like you told me to.

Sarah: Good.

You break the hug and she begins to talk again.

Sarah: So, how's it feel leading and training cadet of your own?

Y/N: Honestly it's a TON of work, but I enjoy it non the less. Getting to scream at recruits and watch them follow your order is quite the experience. Eren, Armin, and Mikasa are candidates to be in the top ten of the class also.

Sarah: Really? Wow, they've come a long way huh?

Y/N: Mikasa is actually ranked 1st, other officers say she could be one of the greatest soldiers alive, next to captain levi even.

Sarah: Who knows? Maybe.

Y/N: Sarah?

Sarah: Yeah wh-

She's cut off by you hugging her tightly. She can't help my but smile and stroke your hair.

Y/N: I missed you so much.

Sarah: I missed you so much too little brother.

Y/N: It's almost dinner time, why don't we get your friend and we can head to the mess hall together?

Sarah: Sure, why not?

You and Sarah head down the hall and you wait outside while your sister gets your friend. You hear talking then a crash which confuses you, then finally she exits with a girl who's shorter than her, has short blonde hair and amber like eyes. She wore a button up shirt that hugged her body and her uniform pants and shoes.

Blonde girl: Hi, I'm Petra Ral. You must be Y/N.

Y/N: Yes I am.

Petra walked towards you swaying her hips, she stopped when she was close to your face.

Petra:Hmmm, so far your impression on me is...

She puts her hand on your chest and moves her hand across your body, she reaches your member and squeezes firmly making you squirm and turn red.

Petra:..very nice~

Y/N: U-uhh um-mm, S-sarah? A little uhh h-help?

Sarah: PETRA!

She snatches her hand back and you sigh in relief.

Petra: What!? I wasn't doing anything!

Sarah: You were touching my little brother!

Petra: To see if he's fit enough to join!

Sarah: YOU HAD YOUR HAND DOWN THERE!

Petra:I have to inspect all aspects of his body, hmph.

Sarah: Ugh, whatever, lets just go, I'm starving.

Y/N: Y-yeah, lets go.

You three begin your walk,but you cling to your sister while Petra pouts. When your reach the mess hall, just as you were entering, you see eren sweep jean's legs and drop him on the floor.

Y/N: Oi what the hell is going on here?!

They all stood wide eyed not knowing you would be coming in.

Y/N: Give me an answer now or we're all going for a ten mile run with your gear and ODM gear!

Just as you were going to move, sarah stopped you.

Sarah: Take it easy, I'm sure it wasn't anything too serious, let it go alright? For me?

Y/N: But th- *sigh* alright only because it's you.

Sarah: Thank you, now, lets eat.

Y/N: Take your seats and continue with what you were doing cadets.

Just as we went to get our food, the door creaked open and everyone froze when they saw Shadis.

Shadis: I heard a lot of commotion coming from in here. Care to explain?

Everyone looked scared, then out if no where, mikasa raises her hand.

Mikasa: We were loud because Sasha farted sir.

Sasha: HUH?!?

Shadis: Not you again.

Everyone tried their hardest not to laugh, it was even difficult for you.

Shadis: Learn some self restraint you.

With that, he walked out and the evening went on, while you were eating with your sister and petra, you swore your could feel sets of eyes bored towards the back of your head, but you shrug it off.

Krista's POV:

Krista's thoughts: Who the heck are those two girls sitting with my future husband?! They better not get in my way.

She tightens her grip on the spoon, almost snapping it.

Krista's thoughts: Y/N IS MINE AND ONLY MINE!

Annie's POV:

Annie's thoughts: Who the fuck are those two sitting with my play thing? If they try and make any move on him, I will kill them.

She grits her teeth while looking at you laugh with your sister and petra.

Annie's thoughts: LEAVE MY PLAYTHING ALONE!

Sahsa's POV:

Sasha's thoughts: Who do those two think they are being so close to my fo- I mean my Y/N!? I'll hunt them both!

She chews loudly and angrily watching you three enjoy each other's company.

Mikasa's POV:

Mikasa's thoughts: I know that one to his right is his sister Sarah, it's nice seeing those two, and honestly I missed her as well, but that other girl better not get any ideas about making a move on Y/N, or she'll go through something worse than hell.

She squeezes her cup tightly, crushing it and almost spilling her drink.

Y/N POV:

Y/N: Well I'm pretty full. You guys?

Sarah: Hunger satisfied! Haha.

Petra: Me too, we should head back.

Y/N: Yeah, I'm pretty tired. Lets go.

You three head off and go to your rooms to sleep. Over the course of training the cadets, two hundredand eighteen managed to press on and pass their years of training.

Time skip 2 nights later:

Tonight was the night that the 104th cadet corps would graduate and choose which regiment they would be joining. The graduation ceremony began at night and all the recruits we're lined up outside with Shadis, you, and a couple other officers on an elevated stage.

Commanding Officer: Tonight is the night you will be given three choices. Instructor Shadis, please list the three choices they will be given.

Shadis: You will be given the of joining one of the three regiments. The Garrison regiment where you will protect towns and reinforce the walls. The Scout regiment where you will venture outside the walls and risk their lives for humanity. Or the Military Police who serve the king, protect the people and protect internal order. Corporal L/N, please explain the procedure of joining the Military Police.

Y/N: In order to join the Military Police you will have had to been placed in the top ten of the cadet corps. I will announce the names in order.

10) Krista Lenz
9) Sasha Blause
8) Connie Springer
7) Marco Bott
6) Jean Kirstein
5) Eren Jaeger
4)Annie Leonhart
3) Bertolt Hoover
2) Reiner Braun
1) Mikasa Ackerman

The ten cadets stood at the front of everyone.

Y/N: This will be the last night you spend as cadets, once you make your choice, you will be officially soldiers. Fall out and change into your civilian clothes and head to the mess hall, the night is yours, I suggest you spend it the best way you can.

After the ceremony ended your sister and Petra caught up to you.

Sarah: Quite the speech little brother.

Petra: You sounded like your our age.

Y/N: Thanks, well time to spend the some time with my friends, this might be the last time I see them.

Sarah: Well what are we waiting for? Lets have some fun before we get back to work, right Petra?

Petra: Right!

Y/N: You guys are too excited for some free time, and I love it! Lets get going!

All: Yahoo!!

They start dragging you towards the mess hall for your final time there before embarking on their expedition.

Author's Note: WELL THINGS ARE GETTING HOT WITH THOSE GIRLS, NOW THERE'S PETRA! Anyways, it's almost time for you to do the job you signed up for. I hope you liked the chapter, and will like those to come. Thanks for reading! Woooo!
