The Secret of Cetacean Ops

The hiss of the door as it opened sounded like an announcement to the whole ship as Doctor T'Ana slipped through it. A ship-wide message proclaiming her private business to one and all. Her tail twitched as the door slid shut behind her, and swiftly the commander turned upon her heel, tapping at the touch-pad mechanism for a few moments before speaking aloud.

"Computer, recognise T'Ana, M.D. Chief Medical Officer, U.S.S Cerritos, rank of Commander."

The computer trilled with a trio of affirming tones. The caitian woman's ears twitched as it spoke to her.

"Voice print identity verified."

T'Ana nodded curtly, and glanced over her shoulder for an instant before speaking once again.

"Seal this door, authorisation code Sierra Hotel X-Ray One Four One. Disable manual override, and play internal warning if any attempt is made to bypass."

For a moment the computer said nothing, and T'Ana felt her heart quicken. An instant later though it chimed warmly again, and the caitian's body returned to its usual slightly slumped, relaxed gait as she heard it announce what she had been waiting to hear.

"Door sealed. Access to Cetacean Ops restricted until further notice."

T'Ana wasted no time in turning away from the door and stepping through the entry corridor into the wider, more open expanse of the Cetacean Ops navigational centre. Even as she walked, she began to pull off the long blue medical coat she wore over her science-blue uniform. She folded it within her arms to ensure nothing slipped from the pockets, and as she reached a small alcove within which several humanoid-suitable, underwater modified environment suits were resting, she bent over to put the coat inside it. Almost immediately though, as she leaned forward and lifted her tail to help herself balance, she heard a whistle from behind her. The caitian didn't stand back up immediately, but she did fight to hide the smile that briefly crossed her resting, somewhat naturally scowling expression. A few moments later she turned, and leaned back against the wall, lifting one foot and beginning to loosen one of her boots as she looked over at the whistler.

"You know, back in the mid twenty first century of your home-world it was considered really fucking inappropriate for a human to whistle at someone else, especially a woman, to indicate an interest in her body."

The caitian teased as she pulled off her boot and allowed her toes to flex, claws extending and retracting before she switched feet and began to remove the other boot. All the while, from where they were bobbing near the closest edge of the large pool that filled the centre of Cetacean Ops, two beluga whales beamed back at her, their own custom-fitted uniform tunics floating discarded in the water nearby.

"Yeah? Well, back then humans still thought we were an inferior form of life, just because they weren't smart enough to understand our language the way we could understand theirs. Besides, how do you know I was complimenting your body?"

Lieutenant Matt chuckled, the audible squeaks and clicks of the whales' highly complex language still audible even as the room's inbuilt universal translator converted his words for T'Ana's benefit. The caitian stopped removing her boot, and raised a sharp eyebrow at the whale. He met her steely gaze for just a second or two, then blinked and clicked loudly once again as he looked away.

"Okay. Okay, fine! I was absolutely admiring your body. But... it really wasn't like you think! I wasn't whistling at your ass. I was saying to Kimolu how much I love your tail."

The other beluga nodded warmly to back up his companion's comment.

"He was, really! We don't get to see many other tails in here besides those on comets."

Matt and T'Ana both snorted with laughter. The cat rolled her eyes, but continued to smile as she tossed her second boot into the alcove along with the first, and started to unfasten her tunic.

"You like my tail, huh?"

The limb in question flicked from side to side, and she watched the two junior grade lieutenants' eyes following it back and forth like an ancient hypnotist's pendulum. The whales nodded, and T'Ana raised an eyebrow.

"So, what I'm hearing is... my ass isn't attractive to you?"

The two cetaceans froze, they looked at one another, and a split-second later they were stumbling over themselves, straining the universal translator to its limits as they both tried to heap praise on the cackling, grinning caitian's ass. She threw her tunic in along with the growing pile of her clothing, and started to push her pants down her legs as she shook her head at the pair.

"Oh c'mon, boys. You know I'm just teasing. And you know you're free to admire any part of my body you like, so long as these visits between us remain an absolute secret. Speaking of which, I assume you've taken down the internal sensors for their weekly diagnostic?"

The whales nodded and clicked an affirmative, not for a moment taking their eyes off the now solely underwear clad feline. Their eyes widened as T'Ana reached to her chest, grasped the base of the supportive, form fitting sports-style bra she and most bipeds with some sort of mammary tissue favoured in the late twenty-fourth century, before pulling it up and off her chest, over the top of her fluffy furred head in one smooth motion. By the time she threw it into the alcove, the two belugas were staring at her not just with awe, but with unabashed lust. She purred softly, and licked her lips as she hooked her thumbs around the waistline of her panties and teased them down too, a little more slowly than was necessary. A long, low rumble echoed around the room as the whales vocalised sub-sonically, and the translator struggled to find an approximation for a few moments before issuing a softer, more mellowed moaning sound.

Without a stitch of clothing left upon her body, T'Ana stepped towards the two whales. She walked right to the edge of the pool, within feet of where their upturned faces were now staring up at her naked, fluffy body, and only then did she pause. Only then did the caitian allow herself the slightest hesitation, though that was all it took for her to see both the men in front of her notice and react. Immediately both Matt and Kimolu went from slack-jawed and single-minded to sincerely warm and supportive, and they moved right up against the edge of the pool, bringing their beaked faces up to lean over the edge with warm, gentle eyes reassuring T'Ana.

The caitian sighed, took a deep breath, and let herself drop to her knees, hands reaching out to touch the two belugas on their smooth, pale foreheads between muzzle and blowhole.

"Shit. I really thought I was gonna be able to keep my mind off it there. Thanks, you two. Your horniness almost did the trick this time."

Their faces nuzzled up at her palms as Kimolu spoke for them both.

"You did so well, T'Ana. You're still doing so well. Remember the first time. You couldn't even get past the corridor, knowing the pool was here. And the week after that, you only got your boots off. You've come so far since then."

T'Ana nodded, and let her hers slide up a little further until a single digit upon each paw was delicately circling the two whales' blowholes. They rumbled again, the computer moaned on their behalf, and the cat leaned forward, bending down low so that each of the pair could peck her on the lips.

"I know. I just... I wish it would get easier. I want to be strong. I want to be able to do this for him... for Shaxs, and not be afraid. He looks so peaceful when we use the Idoban Four programme together. When we sit on the hill overlooking the river. I... when he invited me into the water with him, I wanted to go so badly. To take his hand and let him feel the strength of my pagh swelling with his. I..."

The caitian woman shook her head, her voice trailing off. Matt nuzzled against her hand once more.

"He understands, though. You've told us the rest of that story. You still had an amazing night together."

T'Ana smiled gently. She shrugged, pulling herself a little more upright as she looked at the two patiently waiting whales.

"We did. But... I still want to do this. To get more comfortable around water. To make it so one day soon... maybe on our first anniversary since... since he came back to me, we can visit that programme again, and I can ask him to swim with me. To take off his clothes, to take off my own, and to carry me into the water and hold me, and kiss me, and..."

T'Ana stood up sharply. The two whales looked at one another nervously, afraid that they'd pushed the doctor too far with their encouragements. To their relief though, she responded by taking a step forward, not back, and lowering herself down again onto her haunches, then down onto her rump, so that she could stretch her legs out in front of her and dangle them over the edge of the pool, feet brushing against the warm, gently rippling water.

"I love him, boys. I love that Bajoran beefcake so much that it's worth the fear. It's worth the strain. It's... it's damn well worth the risk of you two knowing that I'm a fucking walking stereotype. The cat lady who's afraid of water."

Matt and Kimolu glanced at one another, then back up at T'Ana's naked body. Matt clicked softly.

"One of the late Bajoran religious leaders, Kai Opaka, once said that fear walks with all of us. Those who are weak seek to hide that fear from others, spending so much time covering its tracks that they cannot find a path that will lead them to the prophets' love. Those who are strong walk beside it with pride. They take it by the hand, and lead the fear wherever they wish to tread."

T'Ana blinked. The two whales shrugged, and Matt spoke again.

"What? There's only so many times a day we can suck each other off before we want something else to do. The ship's database has a whole bunch of cultural works and documents, so, we listen to stuff while we work."

"Sometimes we suck each other off while we listen. That's why Cetacean Ops is always in the top five percent for crew productivity."

Kimolu added, both belugas nodding sagely as T'Ana just grinned. She shook her head in wonder down at the two males, she took a deep breath, and as she closed her eyes and thought of Shaxs, she pushed herself forward and let loose a yowl of instinctive terror as she slipped off the edge of the pool and into the water.

Of course, Matt and Kimolu were there, surging forward and supporting her so that her head never went under, so that she could feel the warm water around herself, against her bare fur, her legs, her arms, the base of her chin, but nowhere more. Not rushing down her throat. Not flooding her eyes and ears, blinding her senses, making all her training and dexterity and knowledge useless. Her heart raced. Her body shook, but she didn't drown. She didn't die, no matter how much her mind told her that she would each time she even considered entering a body of water with any part deeper than her waist. She breathed deeply. She allowed herself to acclimatise to the water, to her presence and continued life within it, before finally she opened her eyes.

A smiling beluga's face greeted her, and T'Ana growled softly.

"Fuck. I hate the water."

She murmured, both the whales' chuckling softly as she clung to them.

"I hate it. I hate it. I..."

T'Ana gasped as Matt began to sink below the surface, and she shifted her grip wholly to Kimolu who continued to patiently float in front of her. She embraced him tightly, pressing her cheek to the side of his muzzle.

"I hate the water. I hate the water. I hh-hhhhaah..."

She felt something. Something pushing between her legs. She couldn't look down and she wasn't willing to pull back from Matt's embrace to try, but she didn't need to. The caitian woman knew what it was because she had felt it before. The gentle nuzzling of a cetacean snout between her legs, and the exploratory flicks of a long, powerful tongue against her nether regions. She squeezed Matt tighter as Kimolu lapped at her from beneath the water's surface, and her frustrated mantra of anger at her situation trailed off as the pleasure blossomed within her while the beluga still with his head above water nuzzled at her cheek, then tilted his head slightly back so that he could bump his snout against her own fluffy, angularly whiskered muzzle.

"A wise teacher once said... the ocean is sex. The seas are passion. Every drop of water is an orgasm waiting to wrap you up within itself."

Matt moaned as he kissed the caitian, feeling the ripples of the water born of his husband's submarine efforts passing around him with each passing second. T'Ana growled softly, and licked the tip of his snout with her rough tongue before whispering to him.

"A wise teacher? Is that what you're calling yourself nowadays? You said that to me last wee-aa_aahhh!_."

Matt grinned as no sooner had she addressed him, her head snapped back and she convulsed for a moment in pleasure as Kimolu's tongue struck a particular sweet spot inside her.

"Was I wrong, T'Ana? Think about how far you've come in the last six months. And think about how much progress you've made since the first time you sat on the edge of the pool and masturbated while we sixty-nined for you. Since you dangled your legs over the edge and let me and Kimolu eat you out."

The caitian woman shuddered in pleasure, but scowled playfully at the grinning, bright eyed beluga before her.

"Just because I'm almost as horny as you two are doesn't mean your whole philosophy of water as a domain built for pleasure is accurate. Maybe I just like cumming, no matter where I am."

Matt clicked and kissed the doctor deeply as she opened her muzzle in a groan of longing, only for Kimolu to surface a few seconds later. The kiss broke, and Matt submerged himself, leaving T'Ana floating freely for just a moment before she realised what she was doing, wailed in fright, and flailed as she tried to grab hold of Kimolu. The other whale pressed himself against her warmly, and picked up where his husband had left off in a manner that suggested he had heard every single word which T'Ana and Matt had said to one another.

"You could be in a holodeck, cumming with any number of partners right now. You could be in your quarters. In the sonic shower. You could be in Shaxs' quarters, waiting for him to finish his shift as you rub your pheromones all over his sheets. But you aren't, T'Ana. You're here. Not just with us, not just trying to do something sweet and wonderful for the man you love, but here in the water, choosing this method to train yourself. Choosing these partners to help you acclimatise. Two horny cetaceans with a thing for terrestrial bipeds, who want nothing more than for every member of the crew to associate slipping into the water with joy and pleasure each and every time."

T'Ana nibbled on her bottom lip.

"Fuck..."

She growled, toes curling beneath the water's surface, legs trying their best to wrap around the head of the beluga eating her out even more vigorously than Kimolu had been just a short while prior.

Fuck, I... I want Shaxs to carry me into that lake. To float with me in the water, to take me in his big, strong arms and... o-oh, Kimolu..."

The whale trembled against the caitian woman.

"You want him to fuck you. He could do it on land. He has. But, you want him to take you into the water, and fuck you there, don't you, T'Ana?"

T'Ana mewled and nodded feverishly.

"You want to see his body glistening and smooth in the water. To feel it sliding over and between your bodies. To embrace and surround you as you press yourselves together."

The caitian's claws pressed against the beluga's thick, blubbery flesh. She let slip a frantic, guttural yowl that the universal translator couldn't handle, but Matt and Kimolu alike had heard that sound enough to know what it was. A name. A Bajoran name translated to Caitian, which neither beluga could understand nor wished to pry about. After all, Shaxs was very private about his given name, and if T'Ana wanted to keep that secret so badly that even on the approach to orgasmic rapture she would not betray it in a tongue that anyone else could understand, they were determined to respect that. Besides, whatever it meant, it was in itself a beautiful sound. A sound synonymous with pleasure, and one that they had only ever heard from T'Ana when she was with them like this. Floating in the water, and thinking of the day when it could be herself and Shaxs' spending moments like this, not just walking or floating alongside their fear but writhing, screaming, fucking furiously and freely with it.

"Now!!"

T'Ana shrieked, clinging to Kimolu's powerful, bare body as she hung on the brink of blissful oblivion. The beluga's reaction was immediate. He clicked and whistled, but before T'Ana could hear the translator's interpretation of his words, the whale lurched backwards, and splashed down into the water with the caitian woman still clinging to him barely a split-second after she took a deep breath, and held it even as her lungs begged her to release it in one final, almighty scream.

Bubbles erupted from under the water.

The pool's surface churned.

For twenty seconds there was near total silence in the room aside from the gentle splash of water against the pool's rim, until finally with an almighty splash not one, not two, but three bodies broke the water's surface. T'Ana was screaming as she trembled between the two bodies surrounding her, between the belugas, whose bodies were oriented vertically against hers and whose prehensile, pointed erections were both probing between her legs, dipping in and out of her one at a time, one thrust apiece before giving their husband the next opportunity.

"Don't stop! Don't-"

T'Ana begged before she was dragged back under again, and the water of cetacean ops churned anew. In those moments of ecstasy, there was no fear. There was no time to think about how she hated water, or indeed to think about anything. There was only the pleasure. Only the joy of sensation, and of the knowledge of who she was doing this, who she was feeling all this for.

More than a standard ship-board hour passed before T'Ana left the water, and when she did, it was only because Matt and Kimolu eased her up on their foreheads and rolled her exhausted, spent body out of it. She lay there twitching, gasping, dripping, panting for air not just because of the oxygen deprivation that had built up steadily over the last hour of snatched, stolen breaths, but because of how exhausted she was. How overwhelmed. Because of how many times she had cum, and, judging by the matted state of her fur all across her thighs and buttocks, how many times she had felt the belugas cum against or within her.

After a few minutes, she pulled herself upright. She purred loudly and unabashedly. She ran a hand down the front of her body and cupped the matted fur of her pubic mound, purring louder as a finger slipped between her outer lips and withdrew, glistening with her arousal and the creamier colour and texture of the belugas' intermingled seed. She licked her lips, wiped the digit off on her already stained thigh, and rose rather shakily to her feet, still dripping wet.

"Thank you, boys."

She murmured as she began to pad across the room to the sonic shower, in place for any non-cetacean crewmember who had either slipped and fallen, or who had been required to work within the pool and had ended up a little damp afterwards.

"Seriously..."

She smiled at the two whales who rested their chins on the pool's edge and peered over at her as she stepped into the cubicle, leaving it open at the front, and allowed her body to be bathed by waves of sound energy which both cleaned and dried her all at once.

"...thank you, for everything."

Soon she was getting dressed again, and by the time her uniform and medical coat were back on, Matt and Kimolu's own tunics were wrapped around their smooth cetacean bodies too.

T'Ana stepped back towards the door, but paused and looked back over her shoulder. She grinned, and twitched her tail from side to side playfully for the two whales' benefit. They whistled to her adoringly. The caitian grinned.

"You tell anyone about this, I'll tear you both new blowholes."

She warned them, but winked as she did so.

"And... I'll see you next week?"

The two whales nodded eagerly, and kept watching the doctor walk away, hips swaying and a slight bounce in her normally slumped posture, until she was out of sight.

They listened for the door-seal being unlocked, for the hiss of it opening, and then closing again as T'Ana left.

With a smile, the two belugas floated back into the centre of the pool, and began to lazily circle one another, rolling over onto their backs so their pale stomachs and richer pink, still swollen erections broke the surface of the water.

"Do you think she'll stop visiting us when she and Shaxs finally get to have their lake rendezvous?"

Kimolu murmured curiously to his husband.

"I hope not. I really like spending time with her, and she's gorgeous. But... if it makes her and Shaxs happy? That's what really matters, right?"

Matt clicked back. His husband chuckled, nodded, and rolled onto his side. Matt did the same, and they pushed themselves belly to belly, trembling and flapping their pectoral flippers as their prehensile erections twitched and curled their tips around one another, rubbing and squeezing the other whale's erection intimately.

"So... what do you wanna do now?"

Kimolu murmured as he and Matt floated and gently humped one another. Before his husband could answer though, the two whales' eyes widened slightly as they heard the door hiss again, and they separated, rolling forward and flat in the water to hide their still twitching, dribbling erections as they heard footsteps approaching across the decking. No sooner had the figure stepped into sight though, any frustration they might have felt at being interrupted during their off-hours or embarrassment at nearly being caught fooling around together melted away.

"Hey, Beckett!"

Matt beamed at Ensign Mariner, who had barely stepped into view before she started to pull off her uniform, much to his and Kimolu's delight.

"Hey boys! So, I have exactly sixteen minutes between my fourth and fifth menial tasks of this shift..."

The human woman murmured light-heartedly, as though it was the most natural thing in the world to be stripping naked in front of two staring, horny whales.

"...and cleaning out the conference room post diplomatic summit will go so, so much faster with a couple of loads and a warm afterglow inside me. Help a girl out?"

She chuckled as she tossed the last of her clothes into an uneven heap on the floor, already walking over to the water's edge. Matt and Kimolu looked at one another, then back at Mariner. They grinned.

"I mean... we've got a pretty busy schedule..."

Kimolu murmured playfully for both himself and his husband as they floated closer to the human woman, watching in glee as her smooth, dark skinned body slipped into the water to join their far larger, more pale forms.

"...but, for a fellow crew-member in need? Cetacean Ops is always open."
