Breaking Cerberus' Cheerleader (Patreon)

I love me some Mass Effect and like most things I love I don't get to write it enough. This started out as a random idea I jotted down when I was supposed to be working on something else. I'm glad I had a chance to turn it into something for you guys! Since it earned less votes in the last poll I decided to make it a mini story. Hope you can still enjoy the lesbian fisting regardless!

“I'm not so sure about this Shepard,” Miranda said, “I don't usually fuck other girls.”

“Trust me Lawson, when I'm done you won't care what gender I am.” Shepard laughed.

Miranda looked up at the fuzzy handcuffs chaining her wrists to the large bar positioned above her Commander's bed with no small amount of uncertainty. Her once sleek black body suit lay in tatters on and around her naked body with both her perky tits on near full display and her hairless pussy hidden only by tightly clenched thighs. Shepard was kneeling on the edge of her bed with her hands resting on her raven haired companions knees. With her characteristic confidence she spread Miranda's legs open wide and promptly slid between them before she could close them again. Licking her lips and nodding approvingly at the already slick outer lips of her tight little pussy Shepard's attention drifted a few inches lower to the tight, puckered hole only a few centimeters below her slit. It visibly tensed in accordance with the rest of Miranda's trembling body and pulsed even harder when the tip of the Commander's finger brushed against it. She playfully traced circles around her soon to be lover's asshole until a few drops of arousal finally made their way down from her uncontrollably turned on sex.

Shepard's middle finger collected the pussy juice dribbling down as one might wipe away tears, lathering her finger in a nice gooey coating of the substance. When her digit was good and soaked she brought it back down to Miranda's perfect ass and pressed it against her backdoor. Surprisingly her hole offered almost no resistance and with only the slightest amount of effort her finger slid up to the knuckle inside. An involuntary moan escaped the Cerberus officer's lips and she instantly blushed with embarrassment. She avoided Shepard's gaze as best she could, trying everything in her power to not give away just how turned on she was. So naturally her body started to quiver and both holes hungrily tensed. Within seconds her slutty body was aching for more attention, regardless of where it came from, and her ally seemed happy to oblige. A second finger, this time her ring finger, quickly joined the first, sliding in with a bit more difficulty but still finding its way into her ass like it was second nature. It was about that time that Shepard started moving her digits in slow, calculated motions to make her restrained companion squirm. For several seconds nothing else happened and she was left to fight and enjoy the pleasure. But then two more fingers were suddenly pressing against her slightly stretched hole and she realized the true intentions of her lustful partner. Miranda was no stranger to the occasional cock up her ass but she'd never indulged anything quite as kinky as what her Commander intended. 

Whether by intention or accident Miranda was given a moment to contemplate what was about to be done to her ass as Shepard shifted slightly. When that brief respite was up her partner continued on with a wide smile. Two of her remaining three fingers pushed and rubbed against the tight confines of Miranda's hole, testing it's resistance and trying everything they could to worm their way inside. The pair of digits already wriggling around inside her only made it harder to maintain composure when they started to spread both themselves and her open at the same time. Try as she might Miranda couldn't maintain focus long enough to stymie Shepard's intention for more than a moment. Having someone finger her ass had long been a favorite part of foreplay and that remained true even under the current circumstances. During one of those brief lapses in concentration during which Miranda was too busy moaning a barely audible curse her Commander finally found purchase. Her breath caught in her throat and she momentarily forgot how to speak as two more fingers slipped into her ass. She was suddenly stretched wider than ever before and unable to do a single thing about it except drown in the pain tinged pleasure that came with such an event. 

Once again Shepard gave her partner a chance to catch her breath and adjust to having nearly an entire fist shoved up her butt. Though that break wasn't nearly long enough for her to get used to the follow up when her red haired lover started spreading her fingers out once again. The once tight walls of her ass resisted for a fraction of a second before being overwhelmed and spreading invitingly wide for any and all things that may want to enter. Miranda gasped and closed her eyes, unable to bear the knowledge that someone was staring down the yawning chasm that had once been her pristine little asshole. Her embarrassment and shame was put to the test even fast that she expected when Shepard's thumb joined the fray and her entire, clenched fist attempted to glide into her body. And though her proportions weren't much bigger than Miranda's it felt for all the world like her Commander was trying to shove multiple Krogan cocks inside her at the same time. The uneven contours of her hand made it nearly impossible to predict how much had already entered and any slightest movement sent waves of ecstasy and pain flooding her body.

Panting like she was giving birth and making almost as much noise as a woman who was Miranda struggled harder than ever against the handcuffs keeping her in place. It felt like she was being split in half by the most sadistic torturer in the galaxy but what truly made it unbearable was just how much she was actually enjoying it. Every twinge of discomfort blended with the pleasure into an strange whirlwind of sensations that made it impossible to think, breathe, or do anything but groan. Even when Shepard's fist finally popped inside and her asshole was given a moment of reprieve as it closed around her far more slender wrist Miranda couldn't recover enough to recall a single rational thought. And when her lover started pushing forward without missing a beat her body fell instantly back into the miasma. Her belly started to stretch and grow from the strain of containing the massive intruder. While small enough to almost go unnoticed the changes continued at the same rate as Shepard's pushing until an almost horrifying bulge was jutting out from her tummy. The gradual widening of her arm was far more subtle than the abruptness of her fist and for an all too brief moment she was able to adjust to the ever widening force filling up her body. But it didn't take long to find her limits and for the constantly increasing width to once more put her right at the edge of madness. 

“Stop!” Miranda squealed, “You're breaking me!”

With all the encouragement she'd ever need Shepard smiled at her ecstasy riddled companion and pushed her fist a little deeper inside. The last few centimeters of her forearm disappeared into Miranda's ass with a soft squish. Her bulging stomach stretched out even further while she let out a piercing cry that was equal parts horror and toe curling pleasure. Neither woman could look away from the lovely distension ruining her flawless skin, the mere sight of it enough to make Shepard's own body tremble with jealous lust. Trying to keep her attention focused on her Cerberus slut instead of herself the Commander of the Normandy uncurled her fist inside Miranda. She moved just fast enough for her raven haired companion to be caught off guard by the sensations yet just slowly enough to make her quiver with frustrated lust. When her palm was completely flat against the slick inner walls of her partner's ass she started spreading her fingers open while simultaneously pushing against the thin barrier that separated her two holes. Miranda's whimpers turned into full fledged moans as the stimulation reverberated into her pussy and the sheer variety of sensations started to hit her at once.

As the combined pleasure of being stretched well beyond her breaking point finally collided with the reality that she was little more than a plaything to Shepard Miranda's long stifled libido finally had the release it had been searching for. Her eyes rolled back so completely they were almost completely white while her back arched until only her head and ass remained on the bed. She gritted her teeth in one last attempt to silence her own pleasure before released a cry that filled the room and the surrounding deck. Every fiber of her being seemed to tense at the same time and for a split second her entire world faded into a single pinprick of pleasure within her. A moment later it exploded outwards in a cascading wave of frenetic passion, her muscles wildly spasming as she lost all control. Her ass gripped her Commander's forearm tight enough to actually make the hardened soldier gasp and an ever increasing stream of juices seeped out of her pussy to drip down her thighs and trickle onto the bed.

Predicting what was going to happen a split second before it came to pass Shepard laughed triumphantly and rose to her feet. With her arm still elbow deep in Miranda's asshole she lifted the half conscious woman's hips up off the bed and curled them back over her face just as the sharpest peaks of her climax arrived. The walls of her asshole clamped down around Shepard's arm, sucking it deeper inside as her cunt pulsed jealously beside it. A few moments later she screamed even louder and a jet of perfectly clear liquid erupted out of her pussy like a fountain. It launched a few inches into the air and splashed down all across Miranda's naked body. Her mouth opened in a frenzy of breathless moans, the noises getting more and more watery the longer her pleasure continued. Unable to stop herself Shepard tried to catch a little bit of her partner's cum in her mouth as well. She'd long suspected her biotic teammate was capable of such a display and finally having the proof was just as satisfying as she had hoped. But even she couldn't have predicted just how much self control Miranda had truly lost. For a moment the stream of clear juices ended and her pussy messily in the open air. But before Shepard could even think about withdrawing her fist a fresh torrent of liquid burst out of her glistening holes, this time bright yellow. It arced higher than her squirt and splashed even more messily across the dark haired woman's already dripping face. Watching with gleeful arousal the Commander finally reached down to her own slit and started rubbing away as Miranda pissed all over her own face.

She'd clearly had a full bladder when Shepard had 'persuaded' her to come in and every drop of urine was being emptied out in one uncontrollable push. If any part of Miranda was bothered by the shameful display she was putting on it was hidden beneath the tumultuous ebb and flow of her continued and seemingly endless orgasm. Even after the flow ceased she continued whimpering like a wounded animal, her sticky face a mask of barely lucid delight. Shepard drank in the sight of her haughty crew member reduced to such a humiliating state as she started withdrawing her fist. Like always she didn't move any faster than she needed to and made sure to maintain just the right pace to keep Miranda continuously writhing and moaning. Inch by toe curling inch her forearm emerged and the once tight little hole that had been wrapped around it remained spread open well after the thickest parts of her muscles had retreated. Only when her fist was finally nearing the stretched exit turned entrance did her slack inner walls finally feel the sensation of Shepard's skin, if only for a moment. Then, with one final tug it was gone and she fell back to the bed in an unceremonious heap. Her ass tried to close but merely pulsed humorously in the open air while her tormenter watched with an almost sadistic glee. 

After a few moments the Commander leaned in close to issue one last taunt before finally releasing her beleaguered charge: “Well Mrs. Lawson, I guess I didn't need a cock after all . . .”
