Author's Note: Hello everyone, I am Chocobo7 I finally had the courage to post something in the six years of knowing and being on this site, This is not my original story this is based of a Doujinshi by Amane-san on pixi.

There are some things that I have changed such as Eren's age which in this she is around 17 or 18ish because of what happens in the end.

I am too much of a coward to actually post my stories so I thought I would, do this in order form me to become more comfortable with posting. Please be gentle it's my first time.

"I believe Eren is actually a woman" Mike said announced suddenly, he waited for this information to compute into his fellow soldiers. When it actually did Levi's teacup cracked in his hand grey eyes staring at him, wide with disbelief. Whereas Hange's, reaction was a little less elegant spitting out her coffee of the table, causing the clean freak captain's eyes to twitch in annoyance.

"What the hell are you taking about Mike?" the Captain demanded, "How could you have possibly come up with a conclusion like that?"

Mike looked at him, elbows resting on the table, his fingers intertwined as he rested his chin on them as he spoke his deduction, "Last week I smelt the blood of a woman on her menstrual cycle that was similar to Eren's, I already had my suspicions because Eren's scent is unusually feminine, and with her spending most her life around Ms Mikasa, who smells very similar to Eren because of how close they are, I simply thought it was her that I was smelling, that is until Ms Mikasa scent changed yesterday to that of a female on her menstrual. So it only makes sense that the previous scent that I had smelled came from Eren Jaeger herself."

The Captain and Major looked at each other trying to comprehend their comrade's words, "Are you sure it's not another female you're sniffing at, and if he's a boy why would he smell like a girl" demanded Levi

"Actually now that I think about it, last week Eren had some stomach pains and was white as a sheet" Hange declared causing all three of them to stop and actually think.

Levi stood up "So," he drawled, "we need some confirmation don't we" he began to walk towards the door.

"Eh, Levi where are you going?" startled by his abrupt motions.

"I'm gonna strip him" he deadpanned, "plain and simple it's the easiest way to find out"

Hange stood up screaming, "YOU CAN'T JUST DO THAT TO SOMEONE!" launching herself at the man, "wouldn't be better if went to go check if she really is a girl"

Dodging the scientist smirking when she tripped and landed on her face, "If he's been keeping it a secret all these years what makes you think he will just confess it to you, Shitty Glasses" the older man stated no getting why they were making a big fuss about it.

"If Eren is a girl she would be of marriageable age it would be a bit problematic and inappropriate for you to take her clothes off" reasoned Mike, he thought about grabbing the shorter male, but decided that it wasn't the ass-whooping he would receive if he picked up the Captain like a child.

Hange caught on to Mike's train of thought, "Yeah Levi are you willing to take responsibility for her, if Eren is a girl." Waving her arms wildly trying to get her point across the stubborn man, she was met with a flat look.

"Responsibility?" a puzzled look crossed his features, "It's okay as long as I marry him right?" Both of them look at him with shock and exasperation on their faces, so Levi just continued, "I wanted to marry him anyways, this is actually pretty convenient for me." With that being said the Captain left the room along with the shell shocked adult for the night.

(Outside)

Out of nowhere Eren sneezed causing Mikasa and Armin to look at 'him' concern.

'Huh, maybe someone's talking about me.' Eren pondered, her thoughts interrupted by Mikasa being an overbearing mother hen.

"Bless you, are you alright Eren? Are you cold? I bet it's because that stupid shitty dwarf forces you to sleep in the basement! I'll kill him!" she snapped her pretty face darkening into an animal like snarl.

'Here we go again' was the only though that ran through the brunette and blonde's head.

Later that night

Cold stormy unwavering grey eyes, stared straight through brilliant Teal Sapphire eyes. Poor Eren was shaking as she sat in seiza position on her bed, 'I wonder if I did something to endanger my life' was the only thought running through her head. Levi kept staring at the young titan shifter, he knew his gaze unnerved the petite brunette so he watched her a little longer before he spoke.

"Eren, this is a direct order", Startled by his deep voice abruptly cutting through the silence like the crack of thunder, causing her to flinch slightly.

"Y-Yes Sir!" she squeaked

"Take off your clothes!" he commanded his voice unwavering as if he didn't just say something inappropriate,

"Yes si…..huh?" pausing in mid phrase, her mind actually processing what Levi just said.

"WHA! WHAAAAAAT!" Eren's voice going up several octaves irritating the hell out of Levi, 'If he really isn't a she then how in the hell would you explain that voice' he thought to himself real quick before barking at the brunette, "Shut up! Your voice is too loud!"

Panicking the poor 'boy' stated to stutter. "W-why d-do I need to t-take off m-my c-clothes?" Eren's mind was racing, why the hell the raven haired captain wanted 'him' to take of her clothes.

"Because, we were discussing whether or not you were a boy or girl," he stated casually his steel gray eyes watch her every movement noticing when the brunette flinched and paled slightly as her body became rigid as Levi spoke, "What a ridiculous assumption, right?" he smirked as he saw fear flash across the tiny titan shifter, watching intently as her hands clenched into fists and began to shake, "I am male" she managed to stammer out, "I don't ever remember being doubted before", she hated how her voice sounded weak.

"Oh? Then show me your proof!" Levi's voice demanded leaving no room for argument, "I'm pretty sure I'm registered as a male in the official papers, sir" her voice wavered like she was trying to convince herself.

"You mean the official paper work that which only contains vague information due to the chaos from eight years ago!" his voice hardened and rose in volume as he spoke, "that can't be considered as proof anymore"

Desperate to find a way out of this Eren began to babble out excuses, "Surely someone from my classes would vouch fo-"

"How long are you going to play stupid?"

Levi was officially done with this whole skirting around the issue bullshit, Eren's whole body began to quake in fear, "among men getting naked is nothing to be ashamed about, right Eren?" He hissed, grabbing a slim shoulder shoving her down flat against the mattress, his muscular legs pinning her small frame, both hands on either side of her head.

"No! I don't …. Please stop!" her voice quivered as her face began to turn red from embarrassment and shame, tears began to well up in her eyes, her small hands gripped at his cravat in a pleading manner. Levi pressed on, even though his heart sank at seeing her cry, "I gave you a direct order didn't I? Take off your clothes!" roughly grabbed on to the front of her shirts and gave it a harsh tug the seams on the fabric of her shirt began to rip, "unless you really want to waste this short or perhaps your trousers." He hated seeing that look of fear on her face; he hated to hear that heart breaking sob leave her lips, her hands flew to face covering her tear-filled eyes.

"Not in front of you Captain, please not in front of the person I love, I absolutely won't, please Captain Levi" her voice was soft her breathing heavy from her minor panic attack. Levi let go of her when he heard those words, now he felt like a complete and utter ass. He looked down once again at her and froze, her normally teal eyes were now a watery green, tear streaks ran down her round cheeks her skin flushed from crying, her blouse was ripped from his rough treatment exposing her chest a little bit enough to see the swell of her breast that was still there even after what looked like two layers of bandages to bind her chest.

He got off of her sighing, as he picked her up and cradled her against him; he began to wipe away the tears he caused and to stroke her hair. "Oi, please don't cry, I apologize," he tucked her head under his chin, "Even if you are a girl, I won't think you deceived me, okay" she nodded sniffling a bit as she wiped the remains of tears of her face, "I won't treat you any differently and I'm keeping the surveillance protocols as they are," he went on, "I-I understand" her voice still a bit shaky from before.

"Also if anyone insults you I will take responsibility" his tone gave no room for argument, surprising Eren causing her to lean back to look at him, "do you really mean that" she couldn't help but ask. She received a flat stare amusement seemed to flicker inside their gray depths, "do I look like someone who would joke about something like this."

"W-well no you don't"

"Then don't ask questions you know the answer to" he deadpanned, "oh and one more thing before we continue" Eren looked at him with her big teal sapphire eyes as she waited for him to continue speaking, " As soon as I finish with a thorough body check of you I'm going to take your virginity," he said nonchalantly as if where discussing the weather. Poor Eren's brain short circuited, she fell of the bed she was so surprised making Levi raise an eyebrow at her antics, "Is there a problem with that or is it something to do with me that make you object like that." He was teasing her, because her face was really cute when she got all flustered as she tried to make it off as if she wasn't what he was looking for in a woman, how she was only a skinny girl with nothing to offer him, waving her hands madly back and forth in placating manner as her face turned a bright cherry red that started on the bridge of her nose and spread everywhere on her face.

"Actually quite the contrary, I don't want do to this unless it's with you, " he turned his head to side and fought to keep the blush off his face, he glanced at her through the corner of his eyes, taking is her flabbergasted look on her face, which turned tomato red, her eyes wide and her jaw dropped, smirking slightly at that he continued, " It goes without saying I'd rather do this with someone I love rather than with a one night stand. With that said let's do a quick confirmation then we can continue," he reached out for her shirt again to lift it up.

"PLEASE WAIT!" she cried out griping at his wrists, Levi at his wits end once again pinned her to the bed as he growled lowly in his throat, "What now?" Never let it be said that Levi was not a self restraining man, he wanted nothing more than to take the brunette beneath him. Seeing the animal like look in those stormy eyes Eren knew he had about five seconds to start talking or he was starting without her, she sat up pushing him back, " I don't think you can really tell what I am when I'm like this, so if you need to," she paused as she stuck her hands under her shirt and began pulling at the bandages on her chest, " you have my permission to fully examine me," she pulled the last of the bandages off and laying back down lifting her shirt up a bit to expose her flat muscled stomach barely exposing her well endowed bust, her face showed her embarrassment. To Levi this image was too much for him; his mind went blank as he started something in him just snapped and he pounced on the young woman before him.

No one saw the Captain or the Cadet the rest of the night or the majority of the next day.

The following day

Mike stood near his superior as he sniffed it for the fourth time before Levi snapped at him.

"Mike quit sniffing me it's disgusting, go away" he swatted at the blonde man his face showing his irritation.

"You smell like Eren'" was the only response he got

"…. I suppose so."

Hange being the nosy person she is, came over, 'did he actually go and confirm it'

"Hey Levi, I have a question." She started off

"What do you want shitty four eyes?" he snapped still glaring at Mike

"Well I know you didn't do anything else to that poor child, but did you actually confirm Eren's gender?" she tried not to sound nervous but from the way Levi left and the sounds that escaped from the basement did nothing to ease her worries. "I mean it's not like you actually laid a hand on some poor eighteen year old girl right? Her worry only increased when the ravenette refused to look her in the eyes. Unknown to Hange Levi was actually recalling last night and this morning's memories.

(Flashback)

Heavy breathing filled the otherwise silent basement, tears streaming down Eren's face in pure pleasure. Her petite hands were on top of the head of raven hair that was in between her legs. The well muscled male was placing kisses on her inner thighs occasionally giving slow licks. Strong arms held down her thighs as he stroked her once in warning before he slipped a finger making her squirm. He waited for her to get used to the feeling before he began thrusting his finger in and out causing her to cry out. "L-Lev- AH! Please just hurry!" she whimpered as he slipped in a second and third finger.

Eren's head was spinning with ecstasy, she could barely form a full sentence only managing to choke out pleads for more and Levi's name. She felt a bit weird having his fingers in her, and then he suddenly curled them inside her hitting a certain spot inside her.

Her body arched like a bow, a silent scream passed through her lips, Levi smirked into her thigh and replaced his fingers with his tongue, lapping and sucking at her core. Muscular arms holding her hips down as she tried to buck up into his mouth as he gave a particular hard suck, he added his fingers alongside his tongue thrusting then in and out to prepare her for what was to come. "L-Levi I-I c-can't take it, please! No more!" her voice quivering, her nails raking across his scalp in a pleasurable way, smirking into her skin he drove his fingers until he felt her body tense and scream tore from her. He continues to suckle her, fluid dripping down from his lips as he continued to lap at her through her orgasm, her oversensitive body twitching with every lick. He leaned back to look at her, skin flushed, cupid bows lips swollen from biting it, her chest heaving trying to catch her breath, those crystal teal eyes filled with tears from over stimulation. He leaned forward to crawl up over her, his body lying perfectly flush against hers, one hand pulled up her chin so he could have access to her mouth, kissing her while his other hand lined his shaft against her entrance and with one quick thrust he push in all the way to the hilt, hitting that special spot inside her.

Eren's moans were muffled by Levi's mouth, she could feel every inch of him inside her, both pulled away from the kiss panting, Levi was shaking trying to restrain himself from just pulling out her unbearably tight heat and going back in again and again until both were too numb to even continue. "T-Tell me when." He managed to choke out, Eren responded by shifting her hips and bucking up against him accompanied by a high keening sound, too far gone to use actual words. Levi's restraint finally broke his hips pulled back like a piston and thrust back forward. Eren's scream reverberated off the basement wall as Levi pounded into her, "C-Captain L-Levi I-I can't, it's too much, no more" he pleads only pushed him to go harder and deeper. The small bed banging into the wall with each thrust, both panting heavily, Levi kissing and biting at the junction of her neck and shoulder, Eren returned the favor my leaving claw marks on his back. Both moving in sync, Eren could feel the heat pooling in her belly again once before, Levi noticed her muscles clenching around him, he could feel his balls tighten in response. Eren could feel the heat and hardness of Levi become even more intense then the world shattered around them. Both crying out in completion Levi still thrusting through the have pushing his seed deeper into Eren's body as she continued to quake as her body tried to recover from cumming so soon after her first orgasm.

(End Flashback)

Hange waited for him to answer her, "Actually about that, I did." was his blunt reply.

Hange however freaked out at his uncaring attitude, "WHAT THE HELL DO YOU MEAN 'YOU DID' LEVI!" her voice rose several octaves Mike stood behind her with an equally shocked face.

Smirking at the pair Levi spoke again, " I told you didn't I, 'it's fine as long I marry her right'?"

Epilogue

Six months later

Commander Erwin stared down at the shorter man and the blushing brunette in front of him, "Levi," his voice showing his minor frustration, "Eren if 5 months pregnant you can't keep dragging her around with you everywhere" He was met with a challenging glare in return and a nervous look from the young woman.

Next day

"Levi, when I said you can't be dragging her around with you, I didn't mean you have to carry her around everywhere" Erwin was pinching the bridge of his nose, poor Eren was blushing so hard her face in her hands, embarrassed by her husband's complete disregard for authority as he snarled at the commander refusing to put her down.

Next day

"Levi! Stop bringing Eren to our meetings and let her rest dammit!" the commander was really wishing that Eren would give birth soon, these past few months have been driving Erwin to his wits ends. Levi merely gave him a flat stare as he tightened his grip around his wife, keeping her firmly seated on his lap.

4 months later

Both parents looked upon the little bundle that rested in an exhausted Eren's arms, after nearly 12 hours of labor and nearly breaking both Levi's and Mikasa's hands, a little baby boy with curly brown hair and stormy grey eyes.
