XO Lawson: Chief Buttslut

"Shepard... I don't thi-"

"Shut up Lawson,"

The second Sarah Shepard was back on the Normandy, and that damnable base had exploded, she had only one thing on her mind. It wasn't the welfare of the suicide squad, nor was it the status of her ship, definitely not the report for the Illusive Dick, and contacting the Council was so far down the fucking list it wasn't visible.

No, as Shepard strode through the hanger her mind was fixated on her XO's fat ass.

Of course, she couldn't very well have a slice of booty right there with everyone watching, she had to at least feign to keep their "relationship" secretive for now, and that meant she had to wait an agonizing handful of hours while her stacked executive officer pushed a shitton of paperwork through to the Cerberus dicks. To be fair however, it gave Sarah time to shower and re-arrange her room for the (probably 12+) hours of fucking she was about to do.

Out went the sheets, out went the books on her shelf, out came several bottles of oils and lotions and lubricants, out came a boxful of "marital aides", and out came a skimpy schoolgirl costume straight from a Fornax shoot.

Yes, Shepard had this all planned for quite a bit, ironically since she'd woken up on that shitty med-bay table, and caught a glimpse of Miranda's rocking body.

As Sarah stood naked outside the shower she mentally compared Miranda's body to her previous paramours, Ashley Williams.

Both definitely had hips, that was for sure, Ashley's being a bit more pronounced due to her latina(?) heritage or whatever, and both had a decent bust that was quite perky due to exercise. There was a difference in the bedroom manner between the two, Ash had a certain... feistyness that Miranda couldn't match, but Lawson was just so damn submissive that Shepard couldn't help but swoon.

Though... when it came down to base looks, Miranda took home the prize, despite being engineered to win.

Drying herself off with the towel, Shepard strode naked through her room, stopping at her wardrobe to pull out her typical boy short-style panties and tank top. Both were purposely a size too small, made to cling even tighter to her athletic form than normal, and she struggled a bit to pull the panties over her bubble butt and over her 5-inch flaccid member. She'd had her cock since boot camp, an... accident at a body-mod parlor, and even still she had trouble coping with it sometimes. Not like she cared though, she'd been bi since middle school, and after she'd shot her first wad she'd fallen in love with the rush of a male orgasm.

Sliding her cock off to the side, she preened the front of the boy shorts, smirking at the way her bulge looked. Pulling on her shirt was much more of a fight however, as her breasts were bigger than Miri's by far. Scaling in at the upper end of DDD, Sara had been forced in her youth to wear athletic bras just to avoid stares, and once she'd joined the military she was pleasantly surprised at how much attention they'd gotten her from squad-mates, particularly the ones with talented mouths. Finally pulling the hem down to her bellybutton, Shepard adjusted the fleshy fun-bags to provide a cleavage valley big enough to stop any man, even Kaidan (RIP).

Satisfied that she was ready for her incoming marathon, Shepard opened the comms to Miranda's office.

"Miss Lawson, your ten o'clock is waiting for you,"

"I've got a lot of paperwork Shepard can we push this ba-"

"You have five minutes, or else I come down there,"

"Shepard you can't be serious, I have all these reports to fill out, and we still have to contact the Illu-"

"Don't give two shits about Illusive Dicks, only dick I care about is mine. Four minutes,"

There was a few seconds of silence before the comms cut out and Shepard heard the elevator start to move, shifting between floors for a few seconds more, and finally stopping at her cabin.

The doors slid open to reveal a slightly flustered woman, raven locks spilling over an extremely beautiful face that wore a look of exhaustion. Not physical exhaustion, but the type of exhaustion a mother gets when dealing with a spoiled child. Sighing, the woman stepped into the cabin, hands on her hips, and shot Sarah a glare.

"Alright. Lets get this done then,"

Sarah recoiled in her desk chair, feigning a look of hurt.

"Oh I'm sorry, last time you were in here all I could hear was someone screaming 'Oh god' over and over again. If we're gonna be bitchy then we can walk our happy ass back down to the office, and I can call Kelly up here,"

Miranda crossed her arms, a look of anger crossing her face. She wasn't happy to have her work delayed, but she didn't intend to come off bitchy by accident. Shepard replied to her look with a shrug as she started to turn the desk chair around.

"What are you doing commander?"

"Calling Chambers. At least she'd greet me with a kiss,"

The final word was punctuated with an over the shoulder look and pursed lips. She was intentionally baiting Miranda, demanding obedience in a small way, and God help her Miranda was falling for it. She crossed the gap between them nigh-instantly, bending down to kiss Sarah, hands cupping the commander's cheeks. The kiss lasted several seconds, mostly due to Shepard grabbing a fistful of Miranda's hair to hold her in place, but also due to the XO's pent up lust after the exhilaration of the suicide mission. Finally releasing the kiss, Shepard smiled up at Lawson, running her hand down over her bountiful chest before pushing her back.

"On the bed. Something for you to put on,"

Shepard felt like a kid in a candy store on her birthday which was ironically the day after Christmas as she watched Miranda disrobe. The outfit fit her well, which was to say it didn't fit at all. The skirt rode too high, showing off her pale white ass-cheeks that'd swallowed up the g-string she wore underneath, and the button-up strained under the weight of her tits, but hung open enough to offer a tantalizing view of giggling cleavage. The outfit was completed by white stockings and a pair of schoolgirl heels.

Last, but certainly not least, was the pig-tailed hairstyle she'd adopted after a few minutes in the bathroom.

Miranda stood in front of her, finger idly twirling a pigtail as she waited for Shepard's next command, her pussy clenching as she felt her submissive streak start to kick in. She wanted to be told what to do, she loved having a commanding lover, and Shepard provided that better than anyone else. Hell, their little exchange over the comms had been enough to dampen her panties, had she worn any under her suit. Unfortunately, Shepard seemed content ogling her body, the fat little bulge in her panties growing slightly bigger each passing second.

"God you're fuckin' hot,"

Miranda couldn't help but blush at the comment, despite how crude it was. Her hips swayed side to side, causing her breasts to gently sway as well. She was getting impatient, Shepard's cock already nearing it's full length from what she could see, and she bit her bottom lip as Sarah finally shifted in her seat.

"Bend over the desk... Arch your back, present that ass to me,"

Miranda did so without hesitation, elbows resting on the desk as she stuck her butt up in the air, Shepard rising from her chair as she did so. Miranda couldn't help but add a little wiggle as Sarah moved around behind her, lifting her skirt with one finger. Letting out a low whistle, Shepard ran her free hand over her ass-crack and down to her nether lips, fingers barely grazing the already lubricated folds.

"Someone's more than ready, but that's not the hole that needs lubricated,"

Shepard leaned over her as she spoke, blowing hot breath onto Miranda's ear as she declared her intent to plunge into her virgin ass.

"C-Commander I..."

"Oh? You think I care if you have objections?"

Shepard pulled her pigtails back with the statement, nibbling on her shoulder as she let out a low chuckle. Miranda let out a gulp at the realization that Shepard was going to have her ass whether she consented or not.

And that made her hornier.

There was little ceremony as Shepard pulled her g-string aside and uncapped a bottle of lube. She let a few droplets fall just above her crack, the cold liquid dribbling down to her pucker, sending a shiver up her spine. This dollop was followed by more, as Shepard spread the shining liquid all over her ass cheeks, occasionally slipping a finger into her crack to probe her anal ring. Then, Miranda suddenly felt the bulbous head of Shepard's cock slip between her cheeks, the slickened tool sliding up and down her generous ass cleavage.

"Shepard... I... Don't you wanna...?"

"Wanna what Miranda?"

"L-Loosen it up?"

"If I wanted something loose I'd just fuck your pussy ms. cheerleader~,"

Shepard entered her on that note, fat mushroom tip deforming as it forced the tight muscled ring open. This caused the humorous facial reaction of Miranda's eyes crossing and mouth screwing up as she attempted to ignore the pain radiating from her butthole being torn open. Shepard noted her frustrated grunts as she started to feed more of her cock in, pushing nearly half the 8 inches into her before Miranda became a bit more verbal.

"Fucking... Shit... Goddamn..."

Miranda's voice was barely audible, swear words being the only audible parts. Each word was punctuated with a thump of her fist hitting the desk, her butthole clenching around Shepard's cock, and the commander couldn't help but giggle at the normally well put together woman's flustered state.

"What was that XO?"

Whipping her head around, Miranda shot her a fierce glare.

"I said, shove the whole fucking thing in my shitter you goddamned BITCH!"

Smirk growing on her face, Shepard grabbed a pigtail in each hand as she braced for ramming speed.

"You fucking asked for it slut,"

In one smooth motion, Shepard stuffed the remaining inches of her cock in Miranda's tight ass, using her pigtails as handles to pull the (now screaming) woman into her crotch. From here it was no less than complete anal devastation. Shepard had little care for her XO's well-being as she sawed her cock in and out of that deliciously bouncy, jiggly, bubble, pale ass that'd fueled so many late night fap sessions. For what felt like hours Shepard shoved her dick into her bowels, ass letting out lewd squelching noises from both the lubricant and the sweat from both woman's bodies. It all wouldn't last forever though, as Shepard felt her balls start to churn as her load readied itself for delivery.

"Fuck I hope you're ready cunt, 'cause I'm gonna pack your ass to the brim!"

Leaning over Miranda, Shepard jammed herself up to the hilt inside her ass, arms wrapped around to grab at Miranda's jiggling tits. Biting her shoulder hard, Shepard came, thick fat ropes of semen flooding the tiny bit of space left in Miranda's abused asshole. The load was so big that it forced its way out between Lawson's sphincter and Shepard's cock, dripping down her leg to soak into her stockings. Shepard rode out her orgasm inside Miranda's ass, hands squeezing those fat tits hard as each wave of pleasure that passed through her, and her eyes clenched shut as she let out gasping moans.

Once her cock finally went soft, Shepard let it slip out of Lawson's newly christened orifice. Stepping back, she took a second to snap a picture with her omni-tool before flopping down onto the bed and passing out, leaving a very horny Miranda to slump down pitifully next to her.

"Oh well... Guess I'll just finish the reports tomorrow," she dejectedly stated to no one in particular before lying down next to Sarah.

She would feel unloved and depressed, except when she laid down Sarah immediately pulled her into a spooning cuddle, kissing her on the cheek.

"G'night Miri,"

Blushing again Miranda snuggled up closer, letting Shepard drape an arm over her.
At least it would be good sleep.
