The sweltering heat of the deep lavender walls made it incredibly hard for Shepard to come up with a strategy; if anything, it made it impossible. The redhead’s body was swaddled with intense, musky heat that sapped away her energy, and called her towards the dark temptation of sleep.
 
“Keelah, Shepard. You had to be nosy, didn’t you. Let’s be honest, I was planning this since I learned you were working with Cerberus, but… I expected you’d struggle like a bosh’tet on the way up.” Tali’s light, thickly accented voice rumbled down to her, heavy muffled but still discernible through her slim body and tight suit. Shepard could feel the walls around her reverberating with every syllable. The walls rumbled, and slowly the gastric sack became more humid, and somehow even warmer.
 
Shepard struggled just enough to get herself into a tolerable sitting position, curling up as much as she could. The warmth was somehow calming despite the situation, and the quarian’s stomach carried in it an otherworldly scent that instantly suppressed every pinch of panic that permeated the commander’s mind.
 
She hadn’t meant to take this things far, that much should have been clear from the start. But Shepard couldn’t help herself; ever since their time on the SR-1 she had been fighting a crush on the engineer, and she was finally taking the initiative to make that clear; Tali had seemed to be reciprocating those affections, and she was more than receptive to efforts to flirt. Perhaps it wasn’t fair to be using Liara’s Shadow Broker connections to investigate, but she had discovered that Tali simultaneously was activating videos of the redhead and her nervestim program.
 
Perhaps she had been more overt than was helpful, especially after the stress of the Omega Relay mission faded, and her long-repressed lust was finally able to take center stage again. She had surprised the quarian by grabbing her backside, leaning in, and teasing the smaller woman.
 
“Damn, Tali, mind telling me how quarians can manage such fat asses when all you eat is dextro paste?” She had said. It was a surprising act of renegade impulsiveness, but she hadn’t expected the quarian to have been so demanding in her response. She quipped back a few answers in a cold-matter of fact tone. The redhead should have left well enough alone, but she pressed forth, undaunted by Tali’s refusal to indulge her horny humor.
 
“What, don’t tell me you’re out there eating Asari to get cakes like that.”
 
Instantly, the quarian spun around, her glowing eyes widening at the mocking accusation. All of a sudden, Tali’s voice had developed a coy, knowing tone, and she swallowed the shock by turning back around and returning her attention to her omni tool.
 
“Did Legion say something?” She asked, before shrugging off her own question. “It’s your lucky day, Shepard. I’ve been taking a lot of medicine in preparation for what you were proposing, but I guess I was still caught off guard.” She chuckled, and punctuated her statement with another quip, but the redhead’s eyes had locked on Tali’s plump ass. Her fingers pressed against her suit, pressing the already-tight catsuit taut, her fat cheeks clearly outlined and on full display. A few quick hisses were enough to remove that barrier, and before long Shepard was offered one of the rarest sights in the galaxy.
 
Tali sighed and leaned forward, her legs spreading wider as she practically bent herself down onto the console. Her ass was a deep, luscious purple, speckled with freckles and circular patterns that seemed to immediately draw the eye to her wide, pulsing pucker. The quarian’s hole was wide, and plush, and the only thought that Shepard had to compare it too was the equines that used to roam on Mindoir. It seemed to flex at her, wide, puffy anal lips moving with hypnotic intent. There was no gap between her hole and her cunt, a comparatively modest and thin lavender slit that simply hung below the hole.
 
To make things even more tempting, both holes seemed to drip with lust, all of the space between her fat cheeks and her inner thighs simply drenched with warm wetness. The gap between the anal ring called Shepard forth, the void the central object of fixation. It didn’t take a minute before the redhead had inched forward, mind hazy from the intense worship of the hole; the human’s mind was numb save for an awareness of Tali’s pleasure. She found herself somehow indoctrinated, her crush mixed with what had to have been pheromones breaking the commander’s strategic mind into something with a singular focus.
 
And then, she had experienced something akin to blacking out. There was a sudden shift in the quarian’s weight against her face, and darkness. All that the human’s reflexes responded with was continued licking, even as the quarian’s squatting pulled Shepard in deeper and deeper.
 
Shepard only came back to herself as her navel was cleared by the quarian’s tight hole, the suffocating grip already pinning her down and restraining her. The infiltrator simply didn’t have any windows of escape; there wasn’t any backing out to be head.
 
The scent inside of the quarian was compelling enough that Shepard mused that this was perhaps a quarian mating ritual. The scent inside was almost like an incense, thick and smoggy and herbal, like an over brewed tea. She breathed in more of the humid air, and her eyes went the slightest bit foggy. Her legs, which were still impulsively kicking, stilled, and the next slurp met no resistance whatsoever. Tali whined and panted, trying to spread her legs wider and wider in order to grant herself the slightest bit more flexibility. Before she knew it, her legs were lifted off of the ground, and she was simply balancing her fat fanny atop the human being stuffed up it.
 
As she whined and shakily attempted to continue her inputs on the console, Tali slowly slid down towards the ground, her gut slowly distending outwards as Shepard snuggled into her pipes. She only stopped typing when her height was no longer enough to reach the input range, her legs slowly pressing against the cool, creaking metal of the Normandy.
 
"Keelah se'lai, you're so heavy!" Tali scolded the human inside of her, giving her massive, bulging gut imprinted with her commander a few hearty smacks, drawing forth a ravenous noise from her guts, an industrious roar as though from a reaper. "Just... let me..." She hefted herself up, her gut practically pinning her against the floor. Her legs wrapped around her stomach as she leaned forward, her hands reaching up to grab the console and heft herself up. "Implant the last little line of code, and..." The moment she hit the button, Tali lost her grip, and with a little squeak she slumped downwards and slammed the rest of her weight against her gut.
 
The impact forced up a thick mouthful of air, the the quarian belched, the ear-splitting release of gas managing to be simultaneously muffled and reverberated by her faceplate; she smogged it up only to release it with a huff, hand reaching upwards to try and displace the humidity yet-to-be filtered out.
 
"Oh, there's a little bit of that fight I expected." She acknowledged, dryly, though she could do little else. She was weighed down by Shepard, similarly restrained from movement in the way that her stomach was pinning the human. "It doesn't matter much. Shore leave starts in a few days, so I've got time to take care of it all." She acknowledged, giving her gut a loving pat. "Thanks for authorizing that, by the way."
 
Inside, Shepard couldn't even manage to respond past a little hum of acknowledgement, one that went unheard by the quarian. The sudden stillness, the hypnotic thumping of Tali's heartbeat, all of it worked in collaboration to weigh her eyelids down, despite the gentle tingling that was beginning to develop into a nuisance. The quarian wasn't far off, a food coma brought about by being overstuffed in a way that the alien had never experienced authentically in her life kicking in.
 
Simply letting out a delighted sigh at her stretched stomach, the quarian softened against it and let her eyes shut, her suit resisting the threat of being ripped open by the additional weight; she was lucky that as a quarian secrets their suits were made with heavily-flexible materials made to cope and recover from stretching above all else. The lingering tension, though, pinned Shepard even tighter, the human inside already beginning to soften as she slept.
 
Tali spent the next three days in a hibernative state, EDI thankfully locking the door to the battery and running the intricacies in an owed-favor to both Tali and Legion. As she slept, her stomach slowly shrank, Shepard losing mass as the nutrients were drawn out of her. Thick beads of mixed sweat from the heat and the gently-condensing stomach acid rolled down her body.
 
Her limbs were the first to go at the end of the first day inside of the chamber, having slept so deeply that she failed to notice; Shepard only roused at the beginning of the second day, squirming slightly in one last bout of resistance against the alien gut. However, the redhead's actions were successful only in expediting her whole demise. Her struggles worked up a thick blast of air into the quarian's faceplate, squeezing the lingering air out of the stomach. Shepard barely noticed a headache as she pressed against the gut with her already-worn legs, before she simply fell into a hibernative state to parallel her predator's.
 
By the time that Tali finally awoke with a start, barely passing three days in her digestive coma, the human was long gone except for a thin presence in the chyme inside of her. Most of her had drained downwards, the nutrients being sapped out of them and already being converted to mass. The dumptruck that had both lured Shepard in and done the dirty deed of digesting her, soon to do the disposing as well, nearly doubled in size, the dextro-woman's derriere giving her an even more obscenely lopsided pear shape. Her breasts were similarly made larger, though she only went up a couple of cup sizes. A layer of pudge settled over her stomach, thick enough that Tali was able to pinch it with her fingers. She giggled and gave it a few bounces.
 
Unlocking the door to the battery, the quarian then hurried off to the bathroom, using her omni-tool to manually hack the cameras around the halls of the crew-deck; she trusted EDI to mask them, but it added additional security to her.
 
EDI was kind enough to play loud music in the hallway as Tali loudly relieved herself, her cries failing to pass through the translator. She stepped out, clearing her throat and hurrying back to the elevator, leaving the Normandy's AI to activate the fans to cover the stench of Shepard.
 
------------------------------------------------------------
 
It was only after her remains had been passed and the quarian who had conquered her was leaving the SR-2 for her shore leave that Shepard's mind slowly stirred again, pulling itself through force of will back into the waking world. Initially, the human found herself floating in a dreamlike stillness, asserting that this was it and she was finally locked into an afterlife. However, as she tried to thrash and move and escape, she proved that she lacked control over her new body.
 
Shepard's efforts to escape were suddenly interrupted by a loud rumbling from above, Tali's voice ringing out and permeating the human's forms. "Ah, there you are, bosh'tet... I figured you still had enough fight in you to last. I suppose that I'll let you know that the geth were based on our own neural networks... I think you're the first non-quarian to know that since we left Rannoch." The delight was dripping in her voice; Shepard tried to think out a few questions, probing further at her fate, but either Tali could not hear her back, or did not care enough to acknowledge them.
 
Instead, the now ex-Alliance engineer used the silence she marinated in to try and puzzle out her current fate. The sudden understanding of a neural network helped her to understand that she was centered within one place; her core was still implanted within the quarian somehow, simply rewired and made to process things differently; the human was shrouded in darkness, but she could still drink in the sweet smell of the quarian, and hear the gentle thumps of her walking alongside the humming hustle and bustle of what was obviously the Citadel.
 
She could feel the constant up and down march of the quarian, and suddenly Shepard had an epiphany; the thought of where she had ended up unpleasant but avoidable. Trapped under the tight, hugging embrace of the suit, Shepard's sensitive form was central to the motion of walking.
 
The quarian marched along the Citadel, passing through three separate wards on the way to her temporary quarters until the team would take its leave for good and she could head back to the flotilla. The walk was long, and Shepard's mind slowly faded back into the background due to the constant, rhythmic motions of Tali's body. As she walked, the tight heat began to concentrate inside of the suit; the quarian's ass began to sweat, Shepard's body getting sticky and increasingly salty; the sentient fat on Tali's backside nonetheless able to both smell and taste the quarian's essence. It was nearly like a massage, the thick cheeks being rubbed and rolled about in a way that cut the human's mind off mid-thought.
 
It was hard for her to keep her lines of thoughts together as the back-and-forth of the ass moved Shepard towards a total anal indoctrination.
 
When she finally reached her apartment for the next week, Tali hummed to herself as she went back to work on a new hacking algorithm. She sat down on the old chair, squishing Shepard down and flattening the fat cheeks down. The human was left with the feeling of the wind being pressed out of her, but despite that pressure no suffocation happened; Shepard instead used the quiet time to try and process her fate.
 
The engineer discovered over time that with a lot of intense focus she could manage small movements. She could cause the quarian's wide cheeks to tense and very nearly clap, and she could flex Tali's hole between her conscious mass. It was enough to grab the quarian's attention, and she rose from her seat with a little noise, hands reaching backwards to grope herself.
 
"Keelah, are you still raising a stink in there?" Tali asked. "Don't worry, I know exactly how to remind you who's in charge now, Commander."
 
--------------------------------------------------------
 
As a fat, blue dextro-dick slammed into her, clawed hands lightly scratching over her cheeks, Shepard was simultaneously locked in incredible pleasure and humiliation. It had taken remarkably little encouragement to get Garrus on his way to her apartment, his plates already open and his dick out by the time that he walked into the room. He had no idea that Shepard was allowed to be a voyeur to their session, and somehow that made it even hotter.
 
The smell of his cock, spicy and intense, saturated Shepard's senses, and as Garrus growled and taunted Tali's anal additions, both women's hearts soared with desire. Shepard had wanted to flirt with him too, but she had been overt with the quarian first: it seemed now that she was somehow getting her way, even if it wasn't how she expected. Tali shrieked and cried out as her hole was split wider than it had even been relieving herself of Shepard, her tight hole proving no match for the naturally-slicked turian cock.
 
"There it is, Tali... I found the right spot." Garrus crooned, hands spreading Shepard's additions wider and slamming against her with even more force, enough to create mind-numbing ripples across the human's entire being.
 
"Ooh, you goddamn bosh'tet..." Tali mewled. "You can go harder than that!"
 
"Benefits of letting a sniper fuck you." He purred. "I know just what spot to hit."
 
Tali came with a shrieking cry, her translator shorting out as she admitted to consuming Shepard; it was a heat of the moment lapse that thankfully Garrus wasn't able to hear, but somehow the human understood it completely. The quarian's language was no longer a mystery to her. When Garrus responded by busting a fat load right into her, perfectly timed, Shepard's mind fizzled. She didn't know that the translator had failed and instead assumed that the turian was getting off to the contributions to Tali's tush. The thought made her body even more sensitive, the taste of the cum left on her even as he pulled out of her hole proving better than any military rations the human had ever eaten.
 
Garrus gave her ass a few pats and helped her zip up, leaving the creampie to slowly drool out onto Shepard's sweat-soaked additions and into the suit to be removed. As the two cuddled, Tali's ass still pressing against the turian's lap, she gave in entirely. For the first time in her entire career, the commander let her will be bent, her mutual love for both of the aliens snuggling her by proxy overwriting her lingering indignation at her fate.
