Notes: Okay, I intended this to be a one-shot, but my brain keeps coming with these crazy ideas that just won't leave me in peace lol. Anyway, I won't update this regularly, I'll update as soon as my brain comes up with another idea lol. This series will feature James/FemShep, Kaidan/FemShep, or even James/FemShep/Kaidan one-shots's, mostly about making the marines obey the orders (lol). So, enjoy it ;-)

Background: Shepard is a real bitch towards her new crew, especially towards a certain young lieutenant that always tries to prove he's worthy of getting a recommendation from her for the N7 program. He never is though, and that slowly drives him towards the edge.

Warning: extreme sexual content and language, and a LOT of swearing. You have been warned.

Takes place somewhere in ME3.

"Faster!" Her voice was firm and tough, always having this tone that made his insides turn. Always commanding him around, always pushing him towards the edge. She holds her small stopwatch in her hands, her gaze fixed on it as her foot silently tapped on the floor. Again, they were here in the cargo bay, trying to set the best score of lifting weights. No, not the best score. It had to be perfect. Only perfection pleased her.

No wonder she didn't get along with everyone. Apparently, she shared a past with Major Alenko, but something went wrong and they never get back together. James always snorted inwardlyat that thought, always thinking that her need for perfection was the reason for the end of their relationship.

He lifted his weights as fast as he could, sweat dripping down his forehead and back, and thankful that he didn't wore a shirt. He always worked out without it, finding out that it's far easier then with a shirt. First he did it because he thought she would look at him and maybe blush like the other girls that would see him shirtless. But no, Commander Shepard didn't even glanced at his shirtless body, always showing her cold and rough side.

Then he just stopped flirting with her because she always shot him a deadly glare and returned with a really mean comment. 'I'm you superior officer lieutenant, I could remove you from the ship' or 'watch your tongue boy' were her favorite phrases.

His breathing was ragged and fast, still he could lift the weights that were half his weight. He didn't know how much time has passed, but he guessed it was almost up. His eyes flew to her from time to time to see and read her expression, but as usual he was unable to read it. She always wore this mask and he never even managed to see past the mask. No matter how much he wanted it.

"30 seconds left." She warned him and he sped up again, his eyes glancing at her to see, to read her expression. Again, nothing. James took very short breaths only to let them out a second later, again and again, until finally the 30 seconds have passed. He heard her click the stopwatch and he stopped, putting weights back into place. He took the nearby towel and washed the sweat from his forehead and neck, looking up at her and waiting to tell him the results. She took out her notepad and scribbled something down before she spoke, her voice cold and formal as usual.

"39. Three more then last time." She said it as if she confirmed the weather outside. James watched her, he didn't know if he should be angry with her or if he should just challenge her to see how much she could lift in a minute. Then again, she would just tell him she'd order him from the ship. She closed the notepad and clicked the pencil, still old fashioned, but that's Shepard. Suddenly she turned and started to leave, and James just couldn't be silent anymore.

"Commander?" She stopped, turned and sighed, the annoyance clearly written on her face.

"Yes?"

"What about the recommendation?" She shook her head and put her hands on her hips.

"You'll get the recommendation when you're fit for the program. Otherwise, you'll still have to improve your strength. We'll see when you reach 50, then we can talk about a recommendation." She turned abruptly and left, and James had it hard to keep calm. Before she entered the elevator though she turned towards him, her narrowed eyes directed at him. James knew why she turned, he saluted her and she smiled in mock annoyance before she entered the elevator. When the elevator door closed he stepped towards the punching bag and hit it hard a few times, clearly letting out his frustration on it.

"Bitch." He hit the bag hard with his right hook, then his left as he mimicked her voice.

"'We'll see when you reach 50'. Vaca estúpida. I reached 39, wonder how much you would make in a minute." He hit the bag hard multiple times before he stilled the bag with his hands, letting out a frustrated sigh. She was slowly driving him mad, not just because she was cold and unbearable. But because his mind reacted to her in a way it wasn't allowed to.

Her long, red hair fell of her shoulders like waves of magma, her blue ocean eyes cold and fierce like the ice on Feros. Her body toned and curved in just the perfect measure and he always wondered if her skin is soft and how would it feel under his rough, calloused hands. How would her tight and wet walls feel while clamped around his length.

He shook his head to stop. This was the point he always did something to distract his mind from her luscious hips and her full rosy lips. In this case, he took a cold shower, not even bothering to turn on the hot water. Slowly, Commander 'I'm a bitch' Shepard turned his mind upside down, and he wondered when this torture would stop, lest he would lose control and have his way with her.

####

They practically ran after her, her murmurings the only thing they could hear coming from her. They didn't understand the words, but they clearly heard she was pissed, immensely. A mercenary that had to sell her information about the Illusive Man but he fooled her, in the middle of a fucking barren planet. She thought the sum of money would be enough to pay his loyalty, but in the end it wasn't enough. Cerberus operatives ambushed them, luckily they could fight them off without getting seriously injured. Shepard though, she did get injured.

Nothing major or severely that would need medical attention. Just a small burn on her upper arm caused by a bullet that somehow managed to penetrate her shield. How she got the wound? That's another story. She was distracted when she heard James yelling at Liara to take cover. Like an idiot she turned to see if her long time friend is safe, then the bullet...scratched her. She roared loudly when she saw the wound, and then she stormed off to the five other operatives which she took out all by herself.

Finally, they reached the Normandy, James was happy for finally having a shower and to rid himself of the armor. He walked towards the showers and finally undressed himself from his heavy armor. The hot water poured down his tense neck and back muscles, helping him to ease the tension.

At first, he just stood there, letting the water pour down his head, shoulders and back. Then he lifted his face towards the water and he let his face muscles relax. He grabbed his shower gel and started to rub his body clean from the dirt that somehow made it's way even underneath the armor. He bought his own shower gel because the one that the Alliance gave for free smelled like crap. No wonder they gave it for free. After a while he was clean, fresh and smelling nicely before he took the towel to dry himself.

Finally, fresh and dressed in his usual alliance shirt and dark blue fatigues he made his way towards his quarters, only to receive a message on his omni-tool. It was from Shepard.

'Comm room, now.'

He shook his head and turned back to make his way towards the comm room. He thought that this was a casual debrief on the mission that failed sadly, but he was confused when he saw Liara storming out of the comm room, clearly frustrated and annoyed. She didn't even greeted him, she just stormed past him towards the lady showers. James shook his head, seems she's already starting to flame our asses, he thought and smiled when he entered the comm room. Shepard was standing in the middle of it, her arms crossed, her foot silently tapping on the floor.

He entered and the door slid shut behind him, and already could he smell her shower gel. Seems she bought hers too, he thought as he tried to will his mind to not show him images of her naked. She wore her N7 hoodie, a white tank top underneath and blue jeans. Jeans. James never saw her in jeans before.

She turned towards him and ordered Joker to turn off the intercom. Of course he obeyed, poor guy was literally afraid of Commander 'bitchy' Shepard. She shook her head as she walked up and down a line, never taking her eyes off from James. Finally, he swallowed hard as he saw that she wouldn't start talking.

"Commander?" Then she came right in his face and yelled, her eyes freezing his blood.

"What the fuck were you thinking?!" He blinked rapidly, but he never got the chance to ask her what she meant.

"Are you insane, for distracting me in the middle of the fight?!" Again, he swallowed and blinked, not quite getting her meaning.

"Commander, I-"

"If you see a friend in danger you help them without yelling out loud 'take cover'! You shut your mouth and help WITHOUT, SAYING, A, FUCKING, WORD!" She punctuated every word as her face became red from her yelling. James now understood what she meant, and he couldn't hold his tongue even if he wanted to.

"Commander, with all due respect..." She lifted her eyebrows as she leaned away from him, crossing her hands in front of her chest as she waited for him to start talking.

"...but FUCK YOU!" Shepard kept her unreadable expression for a while before the words reached her brain. Then her expression changes, and for the first time James can read her expression. It's pure shock.

"What?!"

"You heard me Commander! Fuck, you! Fuck you and your fucking bitching around! Fuck you and your fucking perfection! Again, f-" He didn't even finish the words as her fist flew right into his jaw. He stumbled back a bit, surprised at her attack. When he looked back at her, he saw pure anger written on her face. Oh James, what have you done?

"Say that again and I'll fucking bomb you out of here!" Her voice was loud and threatening, but they're here already, and James had it enough to play by her freaking perfection rules.

"Fuck...you." Then she lost it. She advances on him with all her might, he was able to block her attacks but it totally surprised him to see how strong she actually is. Her figure is small as well as her hands, but she had power, that he had to admit. He dodged her series of attacks, somehow he even managed to grab her hand, mid air. She growled and wanted to shake off his grip, but he held her firmly. She tried to punch him with her other hand, but he caught it too. He grinned, and Shepard almost screamed because of the frustration she felt.

James would be a fool if he wouldn't be aware of this entire situation. Her scent, her angry posture, they're both sweating again and they're alone in the comm room, the rest of the Normandy sleeping. With her hands in his he turned her around and pressed her back roughly to his body. She gasped at the sudden movement, and she had to suppress her gasp when she felt his mouth grazing her ear.

"How's it like...Commander?" He asked, a mocking tone in his voice.

"What?" She tried to wiggle out, but his grip is just too firm when he spoke again.

"How's it like when you're unable to control the things...the people...around you?" Shepard tries to free herself, but he just tightened his grip around her.

"Let me go lieutenant! That's a fucking order!" He couldn't. He knows he should...but he just couldn't. Not when she's already pressed hard to his body, her scent invading his nose. Not when she's so tough, wanting always to be in control. Not this time though. He could already feel the heat and desire pool between his legs when he spoke to her, his voice so deep it's foreign even to his own ears.

"You're not ordering me around anymore, Shepard." With that he started pushing her towards one of the large chairs, holding her wiggling figure in his arms did nothing to stop him. They were here now, and he is determined to be in control of her tonight. She tosses herself in his arms, desperately trying to get away, but to no avail. Her N7 training was worth nothing when she was trapped in the arms of a larger man.

He pushed her knees up on the chair, her hands now held firmly behind her back. Her head hit the chair and she tried to look at him over her shoulder, but in that position, it was hard for her to see him.

"Let me go, you creepy bastard!" Suddenly she heard something click and she tried to bring her hands to the front, only to feel the cold metal around her wrists. He cuffed her hands, she was helpless now, and there was absolutely nothing she could do.

"James, I swear-"

"You're not allowed to speak..." Then he leaned over, his hands stroking up and down her spine as his mouth ghosted over her ear. "...private." He brought his hands to her chest and slowly unzipped her hoodie. Once the zipper was down, he pushed it open and lifted her shirt up to reveal her bra. He couldn't see it, but he felt that it wasn't the standard issue bra of the Alliance. It was lace, and James' cock twitched, involuntarily. He touched her already hard nipples through the bra, and he swore he heard her moan.

Commander 'I'm a bitch' Shepard actually moaned.

James wanted more of that. He continued his ministrations slowly and tenderly, knowing she would want him to increase the pressure. He was right, because she bucked her breasts into his hand, and he couldn't hide the smirk on his face. He caressed her breasts for a while longer before he ran his hands on her exposed skin of her back. She's so soft and so pale, he worshiped every inch of her exposed skin. Then he came to her jeans and he wrapped his hands around her as his fingers worked with the zipper. He felt how hot her skin was, and he heard the small moan that escaped her when her zipper and button finally went open.

He grabs the end of her jeans and slowly pulled then down as he fell on his knees, kissing her exposed cheek. She shivered at the cold air on her skin, but it didn't take long for James' kisses to warm her up. She felt like she's baked in an oven, and her temperature rose when she felt his hands stroking her exposed rear. James though, he had a hard time to breathe. Commander Shepard wore lace underwear.

"Mmmm..." He backed away from her, and she almost whimpered at the loss of his warmth. She heard clothes falling down on the floor, and moments later she felt skin pressed on warm skin. He was naked, and dear god she was dripping. All this play of dominance and switching roles turned her on so much that she had to focus to breathe. Then he grabbed the end of her panties and yanked them down her legs, and he groaned when he saw her already damp with want.

"Oh Shepard...you're already so wet. Tell me..." He kissed a path up her spine until he reached her ear and he spoke "...is this turning you on?" She whimpered, her legs shaking with want because of this entire...play. Yet she couldn't bring herself to just give up control.

"James-" A smack to her rear made her yelp, but the exact sudden pain made her only hornier.

"Answer my question, private Shepard. Is this turning you on?" She shook again, but this time, she gave up.

"Yes, sir." James gently smacked her rear, more of a reward then punishment as he spoke again.

"How much?"

"Very much, sir." He felt her shaking, his own cock twitching with every sound she let out of herself. He wanted so badly to just bury himself inside her and fuck her like there's no tomorrow. But no. He sees what effect this roleplay had on her, so he continued a little more.

"Now, private, as your superior officer, I have to make sure you pass all the exams." He stroked her rear, knowing it would make her crazy. His hand moved between hee thighs, almost touching her center before he retrieves, making her yelp again.

"What I have noticed is the lack of discipline. You're not following orders precisely, private." He smacked her rear again, and again she yelped, feeling the slight burn of his smack almost made her dizzy.

"Now, I can either remove you from duty, or you will have to work for your stay in the Alliance." He moved in front of her, taking her chin roughly and forcing her to look at him as he spoke.

"Please, sir..." He leaned closer down to her, her jaw still held by his hand.

"What private?"

"I will do anything to keep my position, sir." James smirked as he leaned away from her, roughly releasing her jaw as he did so. He walked behind her again, putting his hands on each cheek of her rear before he spoke, his voice low and filled with desire.

"Now, that's a start...private." He said, before he roughly pushed inside her. He immediately felt her tight walls around him and groaned, he closed his eyes to suppress the urge to fuck her unconscious. Then she chuckled, and he lost it. He smacked her hard before he pushed out, then as hard as he could back in, turning her chuckle into a yelp of pain.

"James!" Hearing her scream his name like this was so erotic to him. He never would've dreamed to be joined with her like this, but he certainly liked the feeling of it.

"Holy shit Shepard..." He groaned again, and then he started moving. It was slow at first, testing her, stretching her. Then he continually sped up, until he pumped wildly in and out of her. She moaned at first, then her moans slowly turned into yelps of pain, then into screams. She was so overwhelmed by...this, all of this, that she couldn't feel anything else but pure arousal. James was exactly what she needed. She needed someone that would take the control from her without asking, someone who would oppose her. Just like James opposed her now. Showing her from behind just how much he opposed her.

He never seems to stop as the tightness in her belly increased, her moans increasing as well as he pounds heavily into her. She couldn't keep quiet then, not even if her life depended on it.

"Please James! Oh god please!" He sneaked his hand around her waist and quickly found her nub. He stroked it with his thumb in match with his thrusts, only so he could bring her over the edge. He felt her walls tightening around him, milking him and warming him, until she exploded. His thrusts were long and hard as she rode out here orgasm, his name a long chant falling from her lips. He felt his own desire building up until he couldn't hold it any longer and he came deep inside of her, her name leaving his lips in a rough whisper.

Both were sweat soaked, but none cared. After what felt like hours he finally found his strength and leaned closer to her ear, his now softening member still inside of her.

"Private?" He said as he pushed her long red hair on the other side of her shoulder so he could kiss the newly exposed skin.

"Yes sir?" She said, finally satisfied and content, and in her no bitchy tone. Suddenly she felt him harden again as he bites down her shoulder, a smirk on his face.

"You passed your first discipline test." Was all he said before he began again. This would be a long, exhausting night...in the comm room.
