Hey guys! Long time no write, I know! But I'm back with this smutty multichapter Rivetra fanfiction. I haven't given up on Yours? But I'm in a sort of block. I may just rewrite the entire thing.

I do not own Shingeki Ni Kyojin/Attack on Titan or the characters featured in this fanfiction. That belongs to Hajime Isayama

ENJOY

Petra Ral spent a lot of time thinking about her very serious and stern captain, Levi. She would wake him up in the mornings and she would serve his tea. She was very rarely alone with him and when she was, she wouldn't be able to properly speak or even move. She felt that with her every motion, he was watching her. Was he studying her or was it just a soldier's habit? Regardless, it was enough to make her heart race.

Today, she went around to his office to bring him some important documents from Commander Irvin. Petra gave a gentle sigh as she reached the door. She knocked gently. "Captain, I brought some more papers for you to sign."

Levi sighed. He hated all this extra work he had to do. He was better suited to field work, where he could use his skills for the betterment and preservation of humanity, his penmanship wasn't something he required for titan slaying. He decided to beckon her in anyway "You may come in, Petra."

He eyed her as she entered the room."Sorry for the intrusion, sir."

He was committing her every movement to memory: The sway of her hips, the way her lips looked as she articulated "sir" and her hair, the way it fell into her eyes when she looked at him.

"Don't apologize for such stupid things" He retorted coldly. It was just his personality to act so stern so she smiled anyway. He was not like the commander. They were both serious, yes but Levi had an intensity that Irvin lacked.

She carefully placed the documents to the left of his desk in his to-be-signed pile. Her arm brushed against his causing her to blush. As she saluted and turned to walk away, his hand caught hers. "You look flushed and you're warm, did you catch a cold or some shit?" He was trying to be nonchalant but he ended up sounding crude.

She was flustered and didn't quite understand his sudden concern for her health "N-no, sir."

"Then why is it your cheeks are so red?" Levi asked. She didn't answer.

"Your commanding officer is asking a question, now answer soldier" He said more firmly.

"I-It's because" She hesitated because how could she explain that it was because of him that she was blushing so incessantly.

"Spit it out" He demanded

"I-it's because of you, sir" She replied knowing full well he may not understand or even accept it.

"Because of me?"

"Y-Yes, sir" she could feel the heat intensified in her face now.

"Explain"

"I-I-I don't know h-how to explain, sir. It's just when I'm near you, I don't know how to act or move. You make me nervous. Sometimes I don't even think you notic-"

Without a word, he lifted her onto his desk disregarding the papers there and stood in front of her wordlessly. She was caught off guard by the sudden motion. He wrapped an arm around his waist and pulled her in swiftly. "Do you think I don't notice you, Petra" He questioned

"Sir?"

"I notice you have this school girl crush and I tried to ignore it, Petra."

Petra stared at him shamefully. So he noticed, huh?

"You should know it's against protocol for a officer and his subordinate to engage in relations."

"Y-yes sir."

"But" He sighed "It's impossible to ignore it. The way you watch me makes me painfully aware of you

I notice your ever move. The way you fucking gracefully place my tea, the way you make titan slaying look like a fucking art." He was complimenting her but just not very well. She blushed an impossibly deeper shade of red. "I can't just sit and watch anymore."

"Then don't, sir" She anxiously stated wondering what the meaning behind his words were.

"Then what would you have me do, Petra?" He almost painfully asked. It wasn't like him to be so forward but he had to make sure he wasn't misconstruing her words.

"Kiss me, Sir" She told him. She didn't comprehend what was happening or what she was saying. It's like her body was speaking for her.

He decided to let his actions speak from then on and placed his lips almost violently over hers. Letting his tongue gently run against her bottom lip, teasing her a bit.

Meanwhile, carefully dragging his free hand's fingertips across her chest and down her sides. Levi gauged her reactions. She would sharply take breaths as he neared her breasts and exhale gently when he diverted his hands to more innocent areas. He could feel her rapid heart beat in his hands. He was apprehensive that he had scared her a bit. "Does this make you blush, Petra" Levi cooed

"Y-yes, sir"

"Why? Does it scare you?"

"No, sir. But, You're my superior officer and we shouldn't be-"

He cut her off again "Fuck, Petra, not now. There's no fucking superior officers here. Just me and you." He was on the defensive now. Worried she was off put by his actions. He didn't want to think about consequences, he just wanted to act on impulse.

She barely managed a, "Yes, sir" She was put off by his cussing.

"Levi" He corrected.

"Yes, Levi" she overly emphasized his name.

"That's my good girl" he whispered against her ear, His fingers began wrapping themselves in her hair. She winced a bit when he pulled too hard but he was delighted that he was inciting such reactions from her from a mere tug of her hair. He wondered what else he could get away with. He smiled to himself and contemplated what to do next. He paused for a minute and decided to leave it up to her "What is it you want from me, Petra?"

She let out a long exhale, not realizing that she had been holding her breath. What did he mean, "What do you want from me"? She took a long moment to think about what he meant by the question and it hit her. He wanted to take her and wanted her permission.

"I want you, sir"

"Oh? Where would you like me?" He teased

She didn't know how to answer. Her checks went ruby red and she couldn't articulate a response. Instead she just stared hesitantly at him wondering what he would do with her lack of a reply.

He smirked at her and began undoing the buckles on her harness and the buttons on her shirt. He planted a rough kiss on her collar bone, leaving a mark. "Did you want me here?" Her heart beat picked up but still no response so Levi moved his tongue lower. He settled on her left breast just above the nipple. "Here, Petra?" Her breathing was erratic but still no response. "Well played then, Petra" He was careful about how he said her name. He would look at her as he spoke making sure that she was hanging off his every word.

He started undoing her trousers, slowly and all the while gazing up at her with intensity only matched by the forceful way he removed the rest of her uniform. She was left in her undergarments. He took a step back and raised a hand to his chin. Levi allowed himself a moment to enjoy the sight. He marveled at how beautiful her curves were and how innocent she looked. He loved the was her breasts were shaped and how her skin looked like the milk he put in his tea It's amazing how much the uniform hid from his lust filled scrutiny. "You're beautiful, Petra" He stated.

She was still without words but she nodded in response. She felt beautiful when he looked at her. If you didn't know Levi well, you'd think every look he gave was filled with contempt and judgment. Not here though. Here his eyes spoke volumes. Petra could almost see what he had in mind for her.

Levi pulled out the chair from his desk and sat in it; his gaze never leaving hers. He pulled Petra to the edge of the desk. Levi placed his lips on her hip bone, grazing the skin gently with his teeth, and all the while wondering if Petra would allow him to press further. "Here, Petra?" He coyly questioned again.

Petra inhaled again and felt she had to gain some confidence. She was Petra Ral, she had killed titans and survived in the Survey corps, a place where a high percentage perished ever expedition. She would not be undone by Levi. "L-lower, Levi" She stammered. Shit still lacking in conviction.

Levi craved more from her. He went lower to her right upper thigh and placed a tentative kiss. "Lower you say? Is here satisfactory or lower? Towards your ankles perhaps?"

She grabbed his hand and placed it on her stomach for an instant before she slowly forced it into her drawers. She placed it just at her clitoris "Here, Levi..." She began, "with your tongue, right here"

He laughed to himself a bit,"As you wish" he said in an oddly affectionate tone. He edged her further off the desk to give himself better access. He removed her undergarments slowly, like unwrapping a carefully tied gift, because that's what she was to him: a gift, one that he was staggeringly thankful for.

He started kissing her lower stomach and slowly went lower; the exact trail she showed him so wonderfully just moments ago. Soft moans were already leaving her lips and he was glad to be the cause of such sweet sounds.

He finally settled on the little nub between Petra's legs. He was surprised to see how anticipatory she already was for him. He smirked and looked at her from between her legs. The moment his tongue touched her there, she gasped loudly and pulled off her for a second and brought his mouth to her ear. He whispered to her "Now, you're going to have to be quiet unless you want the entire building to know that I'm pleasuring you, that's an order."

"Yes, sir" Petra whispered back in a delicious sounding squeek

"Levi" He corrected

"Levi..." She whispered back

Then he went back to tasting her sweetness. Lapping it up like it was the only thing left in the world to drink. Through muffled moans, Levi surmised he was doing a bang-up job pleasing Petra. He plunged two fingers into her wetness and that made her cry out "Levi!", loudly.

He removed his mouth again and warned her, "Petra, not a sound or I will stop, remember your orders."

She nodded apologetically. He continued his pleasurable crusade upon her nether regions. She was gripping at his hair and moaning painfully softly; slightly bucking her hips against his skillful tongue. She could feel the familiar build in the pit of her stomach and as she neared her release she had to find a way to signal her release without being too loud. She decided on her method and just as she climaxed she grabbed his hair and pulled him against her roughly.

As Petra finished riding the waves of her orgasm , Levi's lips were everywhere. Her hips. Her belly button. Her ribs. Her breasts. His endless assault of her skin was leaving little marks. He was claiming her. Her body was his to take and no one else's. She didn't have time to catch her breath before Levi began removing his uniform. Through her shallow breaths, she watched as he methodically removed his shirt and pants. Carefully folding them and placing them on the floor. He was naked and glorious in front of her.

His shoulders were broad and muscular as was the rest of his small frame. His penis wasn't anything to laugh at either and she embarrassingly wondered if he would even fit inside her.

"Are you ready, Petra?"

"Yes, sir, I'm ready" She confirmed as he meticulously he lifted her off the desk and placed her facing towards the desk on his lap. He then moved himself to her entrance.

"Say something If I'm hurting you"

Levi entered her slowly but was quick to find an easy gently rhythm. Petra waited for her body to adjust to his size. She gently winced but it was enough to grab Levi's quick attention. "Is this too uncomfortable?" He inquired. She didn't want to admit it but she nodded slightly. Levi slicked his fingertips with his mouth and placed them at her clitoris and began rubbing small circles on it. "This should help,"

Before long, she was grinding downwards to match his thrusts and throwing her head back moaning his name. She felt pressure on her shoulder, it was Levi leaving marks on her shoulder.

"I-I'm coming, sir"

His voice was gruff and deep as he responded "Then come for me, Petra"

The way he said her name drove her over the edge and she came hard on top of him. This prompted his impending release deep into her. Both were left exhausted and exhalted in his office. Petra lifted herself with wobbling legs off of her captain and sat again on his lap nuzzling into his neck with heavy breaths. He lifted his arm to embrace her but it was caught by her hand. They sat there for a long time listening to each other's breathing without speaking.

"Petra, We should probably talk" Levi said.

Sorry not sorry about a cliff hanger ending! Thanks for reading and please review.
