Even in the dead of night the USS Discovery boasted a cacophonous backdrop: the constant low thrumming of the engines, the more sporadic but louder bump and hum of the turbolifts moving throughout the shift, the periodic gasping hisses of air as the ship's environmental systems worked to maintain its equilibrium. Even in the midst of all that noise Cadet Sylvia Tilly was certain that every single (

) sound she made was echoing throughout the ship, but that certainty didn't stop her furtive ministrations. A trembling hand reached up to grab one of her painfully hard nipples and twisted, causing the beautiful redhead to let out a soft moan, the sound waves absorbed by the fabric of her soiled panties currently shoved into her mouth. Meanwhile her other hand remained busy under the thin covering of her Starfleet issued bed sheet, with three fingers plunging rapidly into and out of her soaking wet cunt.
The squishing of her pussy thundered in her ears as she fixed her gaze on the prone form of her roommate Michael Burnham. No movement, not even the slightest stirring, she noted. That was...good. Yes. Good. It would be a disaster if the enigmatic disgraced officer awoke to see this. An utter humiliation if the beautiful and tempestuous Vulcan-raised human were to notice what a debased little slut her new protege was. Burnham wouldn't even realize that it was her fault, that her constant proximity and strident approach to training was what led her secretly submissive junior officer to masturbate in a frenzy every night. Yes indeed, if Burnham woke up and saw this debauched display she might be angry. Angry, in that Vulcan way that translated into cold steely gazes and constrained but sharp rebukes. She might even be angry enough to lash out, to punish the slut of a cadet who had disturbed her slumber. It might be enough to warrant a flurry of blows raining down on the pale expanse of her large ass. It might not even end there though, it might go farther: more blows landing on her large breasts, on her exposed dripping pussy. Oh it would be horrible if Burnham saw fit to put Tilly in her place by pulling her hair and slapping her around, or by spitting on her and dispassionately describing what a useless fucktoy she was.
One hand migrating from breast to breast mauling each in turn, her other hand frantically pounding into her hungry snatch, Tilly's climax overwhelmed her and she buried her head in her pillow as she screamed out a muffled scream. Her gaze having left her roommate, Tilly didn't notice the older officer's eyes flutter open and stare at her as she concluded her intense orgasm.

Every time Tilly jogged through the halls of the Discovery she felt self conscious. The Starfleet issued workout top was designed to keep her bust contained, but there were limits to even the Federation's engineering and so she was acutely aware of her boobs jiggling around as she passed groups of gawking crewmen. Of course she was equally aware of Michael Burnham, maintaining a steady pace just a couple meters in front of her. She looked dangerous, bounding along the crowded corridor without ever breaking her forward gaze. It was as if she knew that she didn't need to be aware of the passing throngs, that she was a greater threat to anything in her path than they were to her.
It's no wonder I'm not making any progress
, Tilly thought as she subconsciously gave her butt a little extra wiggle while passing a particularly slack jawed lieutenant.
I'm surrounded by distractions
. Her eyes were glued to Michaels arms, watching their sinewed movement as they swung back and forth.
Those would feel so good wrapped around me.
She shook that thought aside and did her best to recenter herself on the grueling workout. For the next long minutes her entire mind was locked on the burning and strain of her muscles as she pushed herself to keep up with the lovely pacer in front of her.
She was so dialed into her activity that she almost barreled right through Burnham when the science specialist pulled to an abrupt stop in front of the turbolift doors. Tilly stood there gasping for breath and grabbed her upper thighs as she tried to compose herself while her mentor cast an appraising eye over her that Tilly could feel. After a few drawn out moments Burnham spoke, her voice cutting through the surrounding din without being raised. "You're still performing below expectations, Cadet."
Her breath still labored, Tilly struggled to formulate a response. "I'm sorry Michael. It's just that I didn't sleep well last night, and Lieutenant Hicks was giving me one of his looks and then I got distracted by your arms and-"
"Enough." Burnham's single word interruption stopped Tilly cold. It's command was so absolute Tilly could feel her nipples begin to harden in response. "Your excuses aside, the fact remains that you are not applying yourself fully. I have some theories as to why." Michael's eyes widened imperceptibly, but something in their depths caused Tilly's heart to race even faster. "Your first training instructor at the academy was Lilah Hodge. I reached out to Lieutenant Hodge when I first agreed to help you, and she finally got back to me two days ago. She had some...fascinating insights to share."
Michael's volume dropped at those last words, so that Tilly had to strain to hear it, and when she understood she almost collapsed on the spot. Lilah had spoken to Michael, and had offered her insights. Images flashed across the surface of her mind: Tilly bent over Lilah's lap while the young lieutenant disciplined her with a hair brush. Her tongue being forced into the folds of Lilah's sweet pussy to 'thank her' for all her help. Tilly bound spread eagle on Lilah's bed, while her supervisor idly toyed with and tortured her for hours.
Tilly was so lost in panicked thought that she didn't notice Burnham stepping closer, close enough that she was able to whisper into the cadet's ear. "She explained to me what lies at the root of your problems, and after observing you stimulating yourself at night I have to agree." Michael's breath was hot in her ear. "Fortunately she also had some helpful suggestions for how to deal with it. It seems you'll require an...alternative approach to training and discipline." Tilly felt Michaels fingers brush across her hip bone, light enough that she could almost pass it off as accidental. Even that light touch threatened to overwhelm her. "You'll meet me in the special science lab at 2100 hours." Without waiting for a reply Burnham turned on a dime and strode away, leaving her young friend still gasping away in stunned silence.
