This story draws from my experience in working as a "Concessionista" on a commuter train as well as lewd thoughts during that.

Myumen is a synth working aboard a passenger ship that travels back and forth across the quadrant. His post is a concessions stand in one of the ship's lounges. Things can get a bit dull on the stretch between Betelgeuse and Proxima Centauri. Khaii, Myu's boyfriend, decides to take advantage of this.

Myumen stood behind the counter of the concession stand, elbows resting on the smooth top while his hips idly swayed, sending his long tail reticulating back and forth. The synth was wearing a nice snug shirt and a pair of snug-fitting capris to accommodate for his digitigrade leg configuration. Over these he wore a long apron with the company logo that took up most of the wall behind him replicated to one side, above his nametag.

He had been stationed at this particular location on the starliner for a few tours now, and was used to the pace. It was a nice job, though. He had a view out a porthole across the small lounge the stand was built into, watching the streaks of distant stars travel by while the enormous commuter spaceship kept up its FTL travel. Additionally, he was allowed to tap into the wireless port of the lounge to keep himself occupied, as long as he promptly served any customer that came by. Plus, the guy he was seeing was also stationed on board.

Idly Myumen turned his head on his elegantly long neck to help pan his optical sensors around beneath his visor. The screen displayed representations of an organic life form's eyes usually, like most of his kind. Those eyes normally fairly accurately reflected his emotional state, something he prided himself in for interacting with organics, but he had gotten a firmware update downloaded that allowed him to mask his emotions behind a cheery disposition. It was called an 'emotion filter', but his boyfriend called it 'customer service mode', no matter what the synth did to dissuade him.

He turned his head the other way. No one was in the lounge at all. Between Betelgeuse and Proxima Centauri there was usually fewer customers coming around than other legs of the tour, but in this case, it was particularly slow. Compared to his shifts so far, he found this to be an aberration. Perhaps fewer people needed to head Sol-wards this time of year.

The synth was so lost in thought that he didn't snap to attention until the door under the gate clacked shut. Leaning away from the counter, he craned his neck back to look around to see if the door had come loose or something.

Instead, he saw a very short, four-eared, feathered and grinning organic. One in a similar uniform to the synthetic's, but lacking an apron and tailored to allow his wing-arms freedom. The avali casually leaned against the inside of the counter, looking up at the synth as his plumed tail flicked about in the negative space in front of the door. Surprise and familiarity were mixed in this situation, considering that one: the engineered raptor was most definitely not supposed to be back in the booth and two: this was Myumen's boyfriend.

"Khaii, what are you doing here?" The synth took a step back, his thick tail bumping into the branded wall between two racks of snack products. To his knowledge the avali was having a medical procedure done that he would need time to recover from. Myumen wasn't sure of the specifics, but while being organic, the raptors were designed for solid water environments. Normally they would overheat before reaching at least thirty degrees below the freezing point.

But this starliner's environmental controls ran just below a quarter of the way between the bottom and top of the liquid scale of dihydrogen oxide, and avali needed regular transfusions to adapt to the, to them, extremely high temperatures that most organic life forms lived within.

"You know..." Khaii smirked, putting his knuckles of his left claw under his chin as he leaned that shoulder into the panel behind the counter. "I'm surprised they let such cute synths on the ship..."

Instantly, a series of diagonal lines appeared on Myumen's visor display between the eye markings and the edge of the screen. This approximated the organic phenomenon of 'blushing' where excess blood flooded the cheeks and caused them to change color. This was an excellent external clue to show that the synth had been flustered with so few words from his confident boyfriend.

He turned down his vocal volume. "Khaaaaaiiii...."

Innocently smiling, the engineered organic flicked and swished his tail a bit faster. "Yes, dear?"

"When I heard you were having your transfusion today, I thought I'd be free from your teasing for a while." Myumen forced his head forward, scanning the empty lounge in case anyone had entered. "I didn't expect you to show up during my shift."

"Dropped your guard." Khaii chirped playfully as he pushed off the panel to walk over to Myumen's left leg. "I'd be derelict in my duties if I didn't make sure you blushed at least once." Before the synth could respond, both of the raptor's wing arms were wrapped around his hips from behind, and his downy face was nuzzling along the dorsal surface of his flustered boyfriend's tail.

Myumen shifted his weight forward, placing his hands on the counter again as the blush lines below his eye display grew more numerous and closer together. He squirmed his hips a bit, unable to do much without threatening to send his boyfriend toppling onto the floor behind the counter.

Slowly, the avali bared his teeth at the tip of his muzzle and lightly brushed them along the soft, rubbery dermis of his synth boyfriend, an affectionate nibble as near the base of the thick limb as he could get while both were standing. "Love you, Myu~"

"I love you too." The synth reciprocated quietly, even as he shifted his tail to gently pry the raptor off his posterior, lightly pressing Khaii against the wall as he stepped towards the counter again.

Both perked their disparate ears at the air-seal sound of an automatic door actuating.

Myu's display instantly lost all sign of fluster as he kicked in his emotion filter, turning his head toward the direction of the door.

A tall furred biped of similar proportions to the synth approached, his clothes clearly not any uniform of the starliner's. A smile crossed his wedged muzzle as he saw the menu printed out on the outside of the booth. "Hi!"

The synth smiled amicably to the sergal. "Good day. What can I help you with?"

Khaii kept out of sight, but he slipped around the thick tail, smiling with a glint in his eye. He reached up to the curve of his boyfriend's hip below the level of the counter and gave a stroke with the tip of a single claw.

"Well, I heard the way to get some alcohol was to come to the lounge!" The furred customer boasted.

Thankful for the firmware upgrade, Myumen kept his fidgeting from the teasing touches behind the counter to below the hip. "Yes, ship policy is that customers cannot use their quarters' replicators to produce alcohol. May I see your ID and pass?"

"Huh. Probably a good idea." The sergal dug in his pocket for his identification.

Khaii, meanwhile, turned his attention from the appraising touches to his synth's hip and thigh to tracing the edge of his apron. The avali appraised just how much was visible behind Myumen's apron with it in place, his tail flicking back and forth as his upper set of ears folded down, as if that made what he was planning more stealthy somehow.

The customer held out his pass and identification.

Myumen trailed his ocular sensors across the text on both as quick as he could process them and very quickly went over his memorized age of tolerance list for major species who would be on the ship, subtracted the date of birth from the current date and found that the sergal was of age to imbibe. "Thank you, sir. What would you like?"

"Is that replicator programmed to make a Stalling Spitfire?" The customer pointed to the device on the wall.

The synth nodded. "It is programmed in 1200 regional cocktails and ah-"

It was at that moment that Khaii had struck, deftly tugging on one belt loop with a claw while the other undid the snap that held the trousers snugly against the base of the girthy synth tail.

Quickly, Myumen recovered, his demeanor mostly intact due to his locked-to-cheerful expression on his visor. "...mixed drinks. I'm sure that is in its database." He looked over to the device in question. No way was he pivoting his hips with his belt halfway down the curve of his rubber-lined rump.

Raising the tip of his tail, the synth reached over to the panel on the replicator and stuck it there. The tiny identification chip he stored there was wirelessly read. "Stalling Spitfire." He recited aloud.

The device glowed for a moment, before a glass filled with a clear orange-red liquid appeared within it.

Myumen pulled away from the access panel, careful to only flex the caudal appendage in this operation, then curled the tip of his tail around the glass. He carefully carried it out, bringing it into reach of his hand, then used that grip to set it on top of the counter. "And let me scan your pass here for a moment..."

The sergal, having not put away either card as of yet, held it out towards the synth's head.

Glad for his firmware updates for entirely different reasons this time, Myumen took the pass and pressed it to the reader on the small register built into the counter. He held the pass back out. "That is to ensure that you do not exceed regulated intake of controlled substances while on board. Thank you for your understanding."

The customer's eyes darted between the synth's visor and the reader on the counter, before he reached out to take the glass. "Do I just dispose of the glass in a replicator as well?"

"Yes. Enjoy your drink. Was there anything else?" Myumen kept his tail hovering near the replicator and one of the displays behind him, at the ready to grab something.

The sergal shook his head. "No, no this is it, thank you." He lifted the glass like he was toasting it, before walking back the direction he came, sipping of his cocktail.

The synth turned off his emotion filter to roll his eyes. It felt good to do, even if no one could see.

"What a perfect ass." Khaii muttered.

"Yep. You'd think he never saw a- eep!!" Myumen squeaked, interrupted in his comment by the proof of his misunderstanding of his boyfriend's statement. The unlit black portions of the visor below his eye displays suddenly were filled with the diagonal hashes representing his blush.

The avali finished yanking the snug pants down the synth's thighs, exposing his bare undercarriage to the back half of the concession stand.

Myumen realized he heard the door open, but not close. Turning back on his filter he peeked forward out of the booth and looked in that direction.

The sergal was standing in the doorway, looking back towards the booth confused. "You okay?"

The synth just smiled and waved, nodding, waiting for the customer to fully leave the lounge before leaning back out of sight with a quiet groan.

This motion just brought Myumen's rump back into the reach of his shorter boyfriend. Khaii wrapped his wing-arms around the synth's right thigh, nuzzling the cheek at the very top with a happy trill.

"You know, if you insist on being like that," Myumen spoke with his volume back to normal. He craned his neck back over his shoulder to look down at his much shorter boyfriend. "I'm not going to be able to turn around at all."

Khaii snickered playfully, giving the plump thigh a squeeze in his arms. "I could hide under your nice thick tail, if it comes to that." He tilted his snout up to give said appendage a light nip.

Myu squirmed his hips and sent the organic swaying back and forth just to hold on. The eyes on the synth's display changed to be triangular brackets, emulating eyes closed so tightly that the skin scrunches up around them. "I'm not showing my bare butt to customers!"

"That's right," The avali crooned, reaching his left claw up to cup the opposite cheek with a broad grin. "Because it's miiiine."

The synth pressed his knees together firmly, shifting them forward and back with a squirk of the latex polymer skin sliding against itself.

"If I were so inclined..." Khaii continued in the same half-purr as his playful claim. "I could just crawl riiiiight in."

"I-I'm working...." Myumen stammered, but the base of his tail visibly had hiked up and away from the curve of his rear.

"Better switch into customer service mode and keep it turned on, then." The avali growled lustfully. "Don't think I can't tell you like the idea..." He trailed a claw along the underside of the hiked tail.

Trembling at the touch and the thoughts dancing through his neural processors, the synth let out a weak, lustful whimper. A familiar sensation of something down south pressing against fabric came to him. Myumen's eyes widened as he realized that without pants, that meant... He looked down and saw the forming tent pressing the apron away from his hips.

"Such a naughty boy, getting all needy under your apron..." Khaii chirped, kissing his boyfriend's right cheek.

The door into the lounge opened up again.

Myumen quickly turned back on his display's filter, easing his hips forward until the edge of the counter pinned his apron to his lower belly, hiding the tent from view. This also resulted in pinning his shaft to the panel down there, but he could deal with one disaster at a time.

This customer was another synth, whose body was far more customized than Myumen's was. The employee recognized some of them as being quite expensive, due to taking a long time to adapt the frame for and the materials of construction. It did have the side effect of making the customer's belly and hips be made of clear, colored material, with no sign of the endoskeleton. On top of the price tag, this was showing off that one didn't need to do manual labor.

"Do you have any Nutripack CE47?" The customer asked, slipping their pass card out of a slot on their chest above the clear abdomen, another mod. "I know that's a really specific blend but I just get a craving for junk food, you know?"

Myumen's mind blanked for a long moment. He was supposed to know the inventory. He'd double checked it about an hour before his boyfriend showed up. But something about someone flaunting their wealth at you while having your tiny lover inching his snout towards the cleft of your ass... "Yes, one moment."

The custom customer synth tapped the edge of his card on the edge of the counter in a fidgeting, impatient manner. "Oh, and if you have wine, that's a great mixer..."

Myumen shifted his hips slightly to give himself a little more reach to get to the top shelf of the display behind him and to the left with his tail, snatching up a capsule of the requested blend. At the same time his fingers were working the register, bringing up the product to be charged. "I'll need to see your ID as well, then." He set the Nutripack down with his tail and reached to the replicator to unlock it with his tail-tip again.

Even the eye-roll animation that displayed from the customer's screen seemed custom, like it had been made by an artist rather than developed procedurally over time like Myumen's expressions. On further thought, this synth's visor seemed far higher resolution as well. The other synth pulled their ID out of the same slot.

"What kind of wine would you like?" Myumen scanned the ID on the register, entering the alcohol menu.

"Cab Sav."

Khaii snerked quietly.

Making an exaggerated clearing his throat sound from his speaker, Myumen did his best to cover up his boyfriend's noise. "Cabernet Sauvignon." He spoke towards the replicator.

The device hummed, working on that while the secretly pantsless synth finished ringing up, tapping the customer's pass as he had with the sergal before. He reached his tail into the replicator and looped the tip around the stem of the wine glass, carrying it out.

The avali chose that moment to finish his slow descent and buried his muzzle into the cleft of his boyfriend's rump.

Myumen's tail jerked a bit in his surprise, but he recovered, managing to not spill the glass. He set it down beside the capsule.

"You okay?" The semi-transparent synth slotted his cards back into his chest, before picking up the two drinks.

"Of course. Thank you." Myu rode the line between concise and curt, his visor continuing to show pleasantly cheerful eyes.

Their own visor displaying a squint, the customer nodded and walked back to the door they entered from.

Khaii dug his claws into both of his boyfriend's cheeks with a chirp, slowly pulling them apart to grant him deeper access with his nuzzling.

Myumen waited for the sound of the door closing again to turn off his visor's emotion filter. He squeezed his cheeks back together with a flex. "You are cutting it close, Khaii."

The raptor growled lustfully as his snout was squeezed by the rubbery cheeks. "You'd better sit on me before another customer comes."

The synth turned his ocular sensors back and forth, mind rushing with just how taboo the act was, especially at work!

Khaii pulled the rump back open, giving a kiss at the snug pucker he found there. "You haven't lost your erection at all." The raptor muttered playfully, before taking a slow lick.

Myumen pressed his mouth shut tight enough that the actuators pressed past one another, giving his soft lips the appearance of a zig-zag pattern. His modulated-sounding whimper was muffled by his mouth being held closed as his knees trembled. He swallowed, then pushed off the counter, purposefully going off-balance.

Beneath the girthy tail, the avali's eyes widened. His talons pressed firmly to the floor as the weight of his much larger boyfriend drove his whole snout through the snug elastic ring he'd been pressed to. The ship's artificial gravity was working to shove the plump latex-coated cheeks over his shoulders within a second. Unseen, he just had the biggest grin. Sure, he hadn't expected his cute synth to actually do it... but this was very much a desired outcome.

A mute symbol appeared between the eyes on Myumen's visor as his jaws widened in a silent moan. Thank the gods for that mod he'd bought as well, with the thin walls of crew quarters in mind. The synth slapped his tail to the floor behind him, forming a tripod of sorts around the standing avali. With three limbs, he was no longer off-balance, giving him some control over how he continued to descend.

Khaii pressed his wing-arms to his sides, tucking his own tail against his legs. The small organic knew better than let himself not be a streamlined toy for his big boyfriend. He could feel the snug orifice travel down his torso and over his hips in a smooth, purposeful slide.

The synth's hips touched down on the floor between his tail and feet, knees raised up to fit between the counter and the back wall. The position tugged his apron up away from its tented position, allowing his member to pulse to its full size in freedom. Myu trembled and clenched tightly around his boyfriend's ankles, keeping himself muted. If he hadn't, he was sure he would be moaning with his volume turned all the way up.

Just the plumed tip of the avali's tail was visible from beneath the synth's latexy cheeks and tailbase, but his talons were still pressed to the floor. He squirmed, bending his knees and trying to tug his feet up into the synth's rear entrance to join the rest of him.

Myumen reached under his apron and pressed down on the top of his shaft, pointing it down and away from the drape of his apron. He clenched over the avali needily, running over everything his boyfriend had said to him in his mind, the taboo nature of doing this while on duty, at work... His lower jaw hung slack, tongue dangling out. At the same time, he shot a thick volley of his synthetic ejaculate out. It splattered against the panel under the counter, where it met the floor between his feet.

Khaii felt the internal walls clenching powerfully around him, dragging him a few inches deeper, until just his tail was all that wasn't held inside his boyfriend. The avali grinned broadly, knowing that he'd gotten his big boyfriend off. He let out a muffled, happy chirp, squirming as much as he could under the pressure to keep this high going. At the same time, he could feel the internal surfaces heating up quickly. The raptor felt a bit faint as the temperature rose.

Vents opened up on Myu's back and thighs, revealing cooling fans that revved to life. Under his shirt was a little bit of an annoyance, but he wasn't thinking about that. The synth rode out his orgasm, ocular sensors tilted all the way back to the wall behind him, his head raised towards the ceiling as he gushed the viscous pseudo-seed.

The synth finally came down from his peak, stroking over his stomach through his apron with his free hand. Beneath, he could feel the form of his boyfriend distending his insides.

In his post-peak clarity, he heard footsteps coming from the opposite direction the customers had come. Myumen turned on his expression filter and unmuted. "Hello?"

A black and white canid in a ship uniform with two thin antennae coming from their brow peeked their head and shoulders over the counter. "I heard you fall down from the other side of the service corridor. Are you okay?"

"I slipped." Myumen explained, not exactly lying. "I'll have to clean this mess up before end of shift for sure."

"Well, since there's no customers around, you should do it now. You know, so you don't slip again." The xeno-collie nodded, reaching a paw out to the synth.

Grasping the paw in his hand, the synth grasped the edge of the counter in his other hand and pushed off the floor with his tail. At the same time, he clenched down tight on Khaii, keeping him from slipping out at all. Between those three points of leverage, he got himself upright, glad that any mess was still hidden below the counter. "Of course. Thank you. I'm unharmed."

The pup's antennae lit up with a slight luminescence, but he nodded. "Okay. Don't be afraid to call if you need help, okay?" He smiled and turned to head back to the maintenance corridor.

Khaii wiggled the plumed tip of his tail a bit, exploring just how far he could reach around one cheek, then the other. The trapped avali had only heard one side of the conversation, but he gathered what it had been from context. The raptor felt the warmth all around him gradually fading. The low hum must have been his boyfriend's coolant fans coming on.

"You wanted in there so bad, you can stay until I get off." Myumen removed his expression filter, blush returning.

The avali couldn't help it. He began to cackle with laughter at the wording, tail flailing about between his boyfriend's legs.

The synth blushed more intensely, lips pressing tightly together once more. "You know what I meant!" His voice echoed through the lounge as he clenched tightly around his boyfriend, flexing in sequence. The plumed tail rapidly was dragged out of the open air of the booth. Myumen trembled at the sensation of the feathers tickling his pucker, before he sighed and tucked his tail's base over his rump.

He weighed putting his pants back on to contain the possibility of messes versus just purchasing a container of condoms from his own stand and wearing one of those behind his apron for the rest of shift. Either way, he had to clean up his mess. His tail pulled open a panel and removed a cleaning rag.

Buried so deep inside his boyfriend, Khaii idly thought it was a good thing he just got his transfusion, considering how close to overheating the synth's innards had gotten mid-peak. He squirmed a bit and grinned at the cute modulated squeak that resulted. Staying in there the rest of shift suited him just fine.
