Shepard, Tali, and Garrus had just come from Solcrom's geth stronghold and were understandably tired from its events. The commander was exhausted to the point of not even engaging in sexual activities with his onboard lovers. He remembered Tali's eyes on the data that he downloaded from the stronghold and resolved to talk to her the next the day about what to do with it.
The next day, Shepard awoke to a pair of tongues licking and caressing his cock. He smiled and began his day as normal by fucking the two asari until they were satisfied enough to start their mornings as well. As expected, when the commander reached the mess hall, a soldier reported that Tali wanted to speak to him about something urgent.
Almost as soon as Shepard walked into the engine room, Tali jumped up and begged for a favor as she pulled him away from prying ears. Instead, the commander signaled for everyone to leave to allay the quarian's worries.
"Is something wrong?" Shepard was sure this was about the geth data, but Tali seemed slightly distressed according to her body language.
"You know the data you took from those geth control nodes? The information you uploaded to Alliance control? I want a copy of it." Tali's confidence has risen around Shepard despite the human's apparent power over women. The quarian was a witness to that "power" as well.
"You want to bring this data back to the Migrant Fleet."
"Those files have information that could be vital to our efforts to understand the geth. It could be the key to helping us reclaim our homeworld!" Tali's body language now showed excitement but didn't keep away the distressed aura. Shepard is good, but even he needs to see someone's face to get a good read on them.
"If I give you this data, your pilgrimage is over. You'll go back to your own people." As he said it, the commander realized how helpful the quarian has been and how she quickly became a vital crew member despite being an alien.
"Not... right away. I'll stay with you as long as it takes to stop Saren. But my people need this!" There was a dangerous pause in the quarian's words, and her body language screamed distress at how terrible she was at lying. This made Shepard pause, and his eyes conveyed how skeptical he suddenly was of her words. Was Tali going to take this data and try to disappear back to her fleet? Has she not built a bond with the crew as they have built with her? That's fucked up. Hannah would not approve of these actions.
"Why the hesitation? Hannah would not approve of these actions. Do you not intend to stay once retrieving the information? Hannah would not approve of these actions. Was being on this ship an attempt to complete your pilgrimage, and now you have an easy way out? Hannah would not approve of these actions." With each question, Shepard took steps toward the quarian who fearfully stepped back from the human-biotic.
"Well, to be honest, I asked to join you on your ship because I wanted to stop Saren. However, it no longer seems worth risking my life if I could already complete my pilgrimage. It isn't necessarily trying to find a way out, but it's me making the smartest decision to protect my own life!" Tali was panicking now, tripping over her words in an attempt to placate the glowing Commander. This only proved to make him even more upset.
"So, you don't care about the lives of your crewmates?"
"I do care, but at the same time, it's hard to comprehend all of the weird stuff going on. You're clearly engaged in relations with Liara and her mother, and it has to be some sort of mind control. I spoke to the Matriarch, and she was okay with what happened on Feros. If anything, she looked lustful and jealous as I told her!"
"Everything I do is for a reason."
"Just like killing Fai Dan for getting brainwashed by the same creature that got everyone else? You have an unnecessarily aggressive attitude to men and hero complex to women who 'need to be taught the right way to act!'"
"Everything I do is for a reason! My mother taught me from a young age the correct way to act and treat others!"
"You're a grown man, Commander! Forget your mother and her stupid teachings! She turned you into a heartless monster because she is-" Tali was cut off by the Commander's biotics slamming her back into the wall behind her. The power never stopped controlling her, though. Tali wanted to rub where she got hit but was unable to move because of the biotics.
"Don't. Ever. Talk. About. MY! Mother! HANNAH WOULD NOT APPROVE OF THESE ACTIONS!" With each angry word, the stasis field that enveloped her became more and more intense until it ripped apart her suit and her helmet, leaving Tali in nothing more than skin-tight, light clothing. The quarian gasped and wanted to struggle and get away so she wouldn't get sick from the exposure, but the biotics wouldn't let her go.
"Joker! Clear out everyone for a path from engineering to my quarters and ensure that the asari are not in there!" Shepard was practically shimmering where he stood, and the pilot could hear the anger in the commander's voice. After urgency over the ship's comms, Joker was able to clear that path, allowing Shepard to carry Tali to his room.
The human biotic couldn't help but replay the last few minutes in his head, making him even angrier. How the hell could that quarian say all of that shit? She doesn't need to risk her life? She has what she needs, so she should leave? His mother is a heartless monster?! Tali has seldom had an outburst since she practically begged to be allowed on the mission. Wait, what the fuck? The quarian was more than eager to defeat Saren before, where did that energy go? Was she faking the shit?!
Without realizing his growing anger, Shepard accidentally let more and more of his power seep deep into Tali, shredding her clothes and causing enough pain for a guttural moan to come out. The Commander turned back towards her to see the beautiful, petite, purple alien floating in his harsh biotics in pain. The need to never hurt a woman rang through his head, and he freed her, allowing the quarian to fall on his bed. Tali's head was throbbing; her skin felt burnt and exposed as she attempted to regain her bearings.
After realizing the situation she was in, Tali instantly began to freak out, hyperventilating the air that she shouldn't be breathing in without a filter.
"Commander, why would you do this? This can kill me! This will kill me! I shouldn't be without my suit! I shouldn't be exposed like this in front of someone I don't love! You can't just use me like an asari! You-" The quarian abruptly stopped as she made a revelation. How is she still going? Anyone else from her species would've been comatose in the harsh conditions of a ship. How the hell did she...?
Tali looked down at her exposed body and saw that it had a blue tinge to it. She looked up at Shepard to see if he was still controlling her, only to see the man taking several deep breathes to compose himself after her outburst. He's certainly powerful enough to use his biotics without focusing on them, but Tali could tell that he wasn't doing anything but trying to calm down. That means that... somehow... his biotics are allowing her to accept these conditions! She can breathe the air fine, she's naked, but her body doesn't hurt other than the sting from his biotics-
Wait. She's NAKED. Tali never thought she would be this exposed to a man at her young age, much less an alien! Humans haven't even been around long enough for her to know if this has ever happened before!
Then again... Tali did use him and his crew to complete her pilgrimage and was about to leave. Wait, that's no reason to attack and strip a defenseless girl!
Then again... Tali did disrespect someone really close to him, enough to have a picture framed above his bed. Wait, that was only after she pointed out several terrible things Shepard has done.
But the one thing that triumphs all of this stuff is that he may have made her viable for the universe with his powers, and no one, not even a quarian, has been able to do that. To a high degree, Tali should be thankful. Now that she thinks about it, there is no mind control ability in the universe yet; otherwise, the person with it would have taken over everything. The only way that these girls all love Shepard so much has to be his charismatic energy, imposing power, and admittedly good looks. Even a hardened girl like Ashley is infatuated with the Commander, so maybe Tali was wrong about him.
After all, it's not every day that a handsome alien can swoop into a girl's life to save her and take her on a heroic odyssey. Tali made up her mind and decided to stay with Shepard to defeat Saren and to even pledge her body as an apology/thanks for what just happened. Lucky, this was around the same time that the Commander came to.
Shepard knew that this was his worst snap, but also knew that something like this could happen again. His mother would be very disappointed if he allowed any girl to get past him without learning to be the good woman that the rest are. He will apologize to Tali later while getting her all the medical attention she needs, but for now, she needs to be put in her place!
Shepard turns back to Tali, expecting to feel bad for the quivering girl afraid due to her destroyed suit. Instead, he found a grateful, thoughtful, slightly blue girl. The biotic saw before that she was purple and assumed all quarians were like this as well, but why does it look like he is still using his biotics on her. Shepard checked, but he actually isn't, not even subconsciously! Strange, did he imbue her with biotics, maybe giving her a permanent stasis field? It's hard to remember things that he does with his powers while aggravated.
"Commander, I am truly sorry for the way I spoke about-" Shepard remembered why he was so angry in the first place and realized he needed to fulfill his mother's requirements for girls that don't know how to behave. The biotic interrupted the quarian by quickly moving towards her and pushing her further back onto his bed. Tali was laid on her back, dazed from the sudden movement from Shepard. He jumped on the bed and used his biotics to shred his pants and underwear during the action, then straddled her chest. Tali is old enough to be seen as mature on her fleet, but she knew absolutely nothing in terms of sexual activities.
So when Shepard shoved his erect cock into her mouth while riding her small breasts, the quarian didn't know how to react. Tali saw the way that Arcelia and Liara were cleaning his dick back on Feros, but it wasn't as forceful as this is. Due to her lack of experience, the engineer kind of just sat there and allowed Shepard to move his dick in and out of her mouth, not bringing him the pleasure he wanted. Maybe if she had larger breasts, he could facefuck her with the assistance of those, but the quarian had B-cups.
Tali expected some sort of taste; however, it's just skin; as if she were sucking on her thumb. Shepard's dick uncomfortably pushed into her throat with each thrust, so the main focus was breathing through the nose and not passing out. She wished she had the skills that the asari did to make him finish faster, but for now, the quarian has to just lay there and take it until her commander was satisfied. On the topic of satisfaction, Shepard grew bored of Tali's mouth and made a mental note to have Liara provide some tips to the purple girl.
Tali felt the dick leave her mouth fully this time and looked up to see if the punishment was over. That likely isn't the case, but she didn't want Shepard's oversized dick to break her. The only time it's ever been used is for urination purposes and medical reasons (not entirely sure about the lore, but I don't think quarians have periods), so to suggest something this large is supposed to go in there is scary.
"Spread your legs and open your lips for me." Shepard maintained a calm posture through this rather than fully throwing himself at the girl, but she obviously has no idea what to do or what's going on. Tali reluctantly opened her legs, but confusedly opened her mouth, mistaking the pair of lips Shepard was referring to.
The Commander soon grew tired of the naivety and dragged Tali by her legs towards him until his saliva-lubed cock was aligned with her pussy. The quarian flinched as she realized what was next, but attempted to steel herself in the face of her commander. Shepard pressed against Tali's unused hole gently until he fit just the tip in and the girl groaned uncomfortably.
He pushed his cock inside her until the head and another inch of his cock was inside her incredibly tight pussy and her quarian cherry was gone. It took no more than that and Tali was panting loudly, holding her breath as she got used to the pain coursing through her body.
"Oh God, Commander!" she cried and Shepard waited a minute. They could only hear the sound of the water running in the bathroom, whether it was Liara or Benezia in there, Shepard didn't know. The sound also masked Tali's cries. She whimpered as the cock stayed inside her. Her leg came down and her fists were clenched feeling a cock inside her tight pussy for the very first time (Can you say that Quarians can make fists?).
Shepard had her hips in his hands and she looked up at him while saying, "It hurts Commander, it really hurts!"
Tali's savior soothed her by rubbing her butt cheeks with both hands and smiled before pulling back then plunging back inside. He started fucking her far more gently than he had ever fucked any of the girls he had taught this lesson to. Shepard looked down and saw the light pink sheen of the blood from her maidenhead and felt bad since this is the first time the girl had ever done anything wrong to him, but speaking of his mother was unacceptable. If anything the blood helped her by giving them more lubrication so she should be feeling good by now. The quarian did not want to give her aggressor the satisfaction of knowing how good she felt from her first time, but it got harder and harder to hold back her moans. Her commander continued fucking her tiny box and suddenly got overwhelmed with excitement as he began to release all of his seed. This action rewarded him with an official moan of pleasure as Tali experienced her first orgasm from something other than her suit.
Shepard looked down at the quarian after her orgasm, realizing that he had almost been pushed off of his bed when she climaxed. Was that biotic power? Without needing a biotic implant? The commander may have imbued the engineer with biotic power through his anger, his own power was beginning to shock him! Nevertheless, Shepard felt like he made his point as he laid next to the panting quarian. His cock was still rock hard, but he may have traumatized Tali too much to try anything else with her... for now.
Tali'Zorah felt a mixture of pleasure and pain but didn't want to admit just how much of the former she felt. Although the quarian was willing to give her body up to the commander, she wished he did it gently or even gave a kiss or two. The main issue that Tali was having, however, was how much she suddenly wanted to submit to him. As his semen settled in her womb, she couldn't help but look over at his still standing dick and want to pleasure it until it was satisfied. Her commander merely wanted to teach her a lesson, right? And he did a great job, right? That's the only reason she felt this way, right?
After the number of women the Commander has worked with, he wasn't surprised to feel Tali's three-fingered hand wrap around his cock and slowly start stroking. Now, Hannah will approve of this girl's actions.
