Ul'vetra - Cowling rut
With a late night shift and an order to be fulfilled at first morning light, it can be a bit stressful when things aren't going as planned. Though not work-place safe, working out that aggitation with a friend makes it far less stressful.

"Aft hydraulics are in order; checking the wiring now, but the engines look to be all in order for high altitude flight." The other mechanic leans over from where they sit on a stacking of crates - diagnostic wires laid cross between them and the tail sections access hatch. "Any luck in the gear shaft?"
Renn heaves a grunt, forcing himself up into a sit. "we'll need to prop it, can't see where the jam is from here." Folding his legs beneath, from a sit to crouch, he stands. "I'm done fucking with it - anymore and I might do something stupid."
"Any broken wires?" A head shake. "Nothing mechanical?"
"It's got to be a wiring problem somewhere in the belly, and I don't have the schematics." Renn leans against the crates, watching over the simulation run the pachyrsis is putting the navigation through - the physical properties of the ship grinding above them "How much longer do you need to run it."
"Another 45 to be absolutely sure it's cleared." The larger mechanic tilts their vision to their coworker, both shadowed by the ship beneath the hanger lights. "Need a cooldown?"
"If we're going to finish this by morning," the silivosha huffs, his tail gracing along the heat scuffed floor. "Either need to get scrambled or work with another problem on the checklist."
"Isn't the landing gear the last one aside checking the cockpit lights?"
Renn groans. "Yep, and I've been putting it off all night."
Glancing towards the diagnostic run, Varinc sets it aside. "Alright, let's see if we can't loosen you up a bit."
The pachy's hands are rough as they grab the strap of his dirty overalls, guiding him from the open hatch siding and closer to the vessel's third engine.
It's a grip that remains firm in spite of the engine grease, tracing over the tail crest cover and further towards the proximal fins that lines Renn's wandering tail. Teasing, taunting further intimacy as Renn takes full grip of the pachyrsis' shirt - a grip made easy through the specialized ribbed palm. "We got five hour before the cutoff. Better make this good, or it'll be on both our tags."
"Oh, don't worry," the curved crown pachy rumbles, their hands fighting to get Renn's tail section loose, wiping their palms clean of gear lube oil. "Cargo that important, huh."
Heaving a sigh, Renn looks down as he undoes his shoulder straps. "Enough that they decided to hold onto the service manifest. So don't even have an idea of how much stress the parts have gone through the last ten cycles." Large claws dig beneath his work overalls, pulling them so he is relieved of the protective clothing and letting his pants be the only thing separating him from the plasma blasted engine metal. As his legs are pulled from the clothing restraints, he tosses his gloves aside - a ring of grime left halfway up his arm.
"Any idea of the manufacture date?"
"Old enough that it gives me a fucking headache," Renn grunts, sitting back as Varinc works to unbutton his work slacks, letting his legs stretch as his boots still remain tied. Taking pause, he slides down from the overshadowing inlet engine cowling. "You should clean your hands, for fuck sake," he offers assistance as the mark of greasy hands only make their actions more apparent. "Let's not give the boss any suspicion, okay?" And undoes the frontal buttons, the straps lying aside as Varinc steps away. "Grab the grain oil while you're at it," he calls over.
"We really should just pack up some supplies when we get a shared night," they grunt, setting the impromptu bottle of lubricant aside - one of the few things safe enough to use in the hanger. Chucking the towel aside, Varinc pulls the flaps of their pants open. To bare themself as Renn just quickly cleans off the grease marks around the pachy's buckles.
"What's the fun in that," Renn chuffs, throwing the towel beside his discarded clothing as he crouches. "Can't let us get too distracted."
"You're one to talk about distractions." Varinc barks with a laugh, their second row of teeth bared as their hand takes grip of Renn's head, plying through the coarse hairs as the silivosha leans into them. Guided down towards the heavy sheath that weighs into the opening of their pants.
"Yeah, I'm a hypocrite," Renn laughs - so very aware of the size that awaits him.
As his hands cup the pouch of skin, fingers trace along the hefty size, easing the resting balls to heave against the opening in the pachy's pants. It's tantalizing as he stares, playing with the sheath as it weighs uneven in his hands.
His mouth presses above the peak of flesh, breathing against the underside of Varinc's stomach before tracing down, teeth roaming along the flocks of fur until he finds ground at the folded skin. It's warm as his lips make contact, tracing along the inner edges in search of the tempting tip.
It's an easy find - giving a gentle stroke with a smile.
Kissing it, letting himself indulge against the heavy sheath, Renn is careful as he coaxes it as claws pull through his coarse hair. They play against his sensitive spires as his tongue presses against the folds, drawing his dark textured tongue around the elegantly sloped tip, around the dawning size fit so easily behind the fat sheath - and it begins to press back just as zealous. As it's weight grows, unable to remain shrouded by the pouch of skin, it begins to take to his mouth. Mouthing around the growing girth, Renn can't help but to invite it inside as it still remains soft against his tongue… that is until the tip presses hard against his throat, gagging before he is able to pull away with a cough.
Yet, he still continues to work the rest as his hands cradle the generous girth weighing heavy in his hands. Strokes accentuated by his dragging kisses, feeling along the tempting girth as his mouth plays gentle along the tip - head leaning into the glides along his scalp.
The silivosha has already drawn himself flushed.
"Alright," Varinc huffs as they watch Renn work their hands around the flaccid length. Catching sight of the similar tent that peaks in the silivosha's lower garments. "Come on, we should get you prepped."
"Right," Renn stands - barely meeting height with Varinc's broad chest.
And he's lifted back into the engine, legs dangling outside as the overalls are formally discarded. And claws draw through the hem of his pants, reaching around towards the buckle that keeps it in place over his broad tail. Leaning back, indulging in the sight of another undressing him, Renn's secondaries cup around his twinning erections, pawing at himself as they are eventually freed from his constrictive moisture trapping pants. They're only pulled partly down his thighs - allowing enough access for their impromptu romp as claws drag along his damp scale-sleek skin.
Varinc's plated skull rests against Renn's, and their mouths meet lips to plate teeth as their hands begin to wander. Cupping and playing, teasing as warmth presses against warmth as the harsh external teeth grant open for the silivosha's gentle kiss upon smooth yet sharp internal row. Renn finds reprieve as claws take over around his flaccid claspers, sinking into them as his secondaries hold onto wrists, his primaries taking their enjoyment against the pachy's expressive ears. Stroking, giving into the abject restraint for the other - their tongues meet as Varinc's head tilts.
Their sharp teeth press against Renn's cheeks as the silivosha kisses their tongue, indulging as it begins to part lips and taunt into mouth gapping thrusts.
It gives way for a clawed hand to roam over Renn's sides, thumbs pressing at the structure of the surface gills that are still hidden well beneath the smaller mechanic's tops. Where gentle pressure is applied, teasing underlying strength as their weight leans in through the slow drawn tongue thrusts; it begs Renn to breath shallow, fingers pulling along ears and wrists as claspers eagerly twitch.
And, finally, it relents - and the plated maws moves south.
Hands hold over the pachy’s horned skull as their mouth traces to the cusp of one hip, generous in the surface nips as the loose top is pushed aside and a single hand works the claspers as one. The strokes are firm as thighs are brought to metal, hips shifted forth as the lower row of teeth graze over heave of the inner thighs, tracing nips to sensitive skin as huffs are drawn from the smaller silivosha, teased as a firm tongue draws towards the folds of his groin.
The claspers are suddenly left abandoned; flexing unattended as a thumbed claw parts his heavy lips from below - and a daunting mouth makes its mark, gentle as the pair is lifted into a plate maw and drawn against the powerful tongue.
"Hmph, fuck, Varinc," Renn huffs as he lies back into the silent engine, hips shifting towards the dancing tongue between his captive claspers. He grips the edges of the engine cowling, secondaries against plated crown, welcoming the attention to his loins with a forgiving sigh.
Sucked to perk the pairing of baggy claspers remain erect as Varinc pulls away. But only for a moment as a hand takes both, easing them aside as sharp teeth graze them along his stomach - a sensation that makes him coil and shiver as the tongue continues to bathe him with attention. All the same a pairing of claws parts his lips between pressed thighs, poking and prodding into him, finger thrusts made gentle as he remains captive to the pachyrsis. A single of his claspers is welcomed back to the tongue crafted suction as Varinc partakes in Renn's body.
Renn's tail shivers between them, the underside stroking the pachy’s awaiting erection.
As claws once again roam between the silivosha's thighs, he welcomes them to guide him exposed. They pull his legs to lie aside the engine's inlet cowling, shuffling him so for his claspers to peak out between his exposed thighs.
And it's where they become bathed in attention, where a vengeful tongue wanders beyond the throb of twinning claspers - to partake in the parted lips with a rumbling growl. The claspers rub against their palate as their strong tongue makes due - prodding, protruding, coaxing mucus from parted lips to share it back around the aching claspers, sucking them firm as questing fingers hold Renn in place.
Back and forth, Varinc sucks the claspers firmed, indulging in the moaning tremors that roll from the silivosha as all he's able to do is hold his shirt, his thigh, their plated skull.
"How far do you want me," growls as Varinc stands back against Renn. They right him as they lean over the smaller mechanic, enamored by the wet 'pop' that sounds as the twinned claspers find their usual place. Pressing them hips to hip, their immense girth rests between claspers and thighs. Far too much for Renn to comfortably fit past his lips.
"We might as well go all the way," Renn sighs, a hand taking grip of the pachyrsis' tip. "Why'd you think I told you to get the grain oil." Smirks.
A chuff, and Varinc hold around both of their parts, pulling Renn against them as their hand holds the claspers around their erection. “Thought you'd want to be fisted," a joke, their hand too broad for Renn's pelvis. "Lie back, will need to stretch you out first."
Renn heaves a steady breath, hips striking back to the firm grip holding around him. “You’re free to give me a try, been stretching out lately,” laughs as he parts himself with a secondary hand, watching as Varinc fetches the grain oil from below the engine. Right next to where his overalls have been abandoned. “Been going through the paces with a friend lately.”
Setting the bottle of grain oil by Renn's hip, Varinc pets him between the risen thighs. "How are they? Doing you well?" And their claws part the silivosha’s inner thighs, giving space to stroke fluid back around the heavy perked claspers before pulling them back.
"Yeah, he's a bit of a hardass, but damn does he love to cuddle." Renn relaxes on his elbows, watching as Varinc works around them.
Letting their drool drip over the twinned claspers, claws begin to stroke down further, parting between heavy lips. "Who is he?"
"You wouldn't know him; Rhomataur, works odd jobs, came here a few months ago from another port."
Varinc smirks, a chuckle, “it's the tentacles, ain't it."
Renn grumbles, "you know how few of either of us there is around this sector. It's nice to be able to share soak hours with someone." And he watches as the pachy's mouth returns to him, a sigh relieving as the folds are parted again by tongue. The strokes are broad inside him, begging his hips to hitch with a grunt as his sigh lies half-cast, watching as Varinc pulls back. And spits.
Tongue pushing his tail aside.
Renn lets a low groan slip as the tongue begins to massage, where saliva begins to drip around the underside of his tail. Lying back, arms crossing over his temple, he watches beyond his raised thighs and perked claspers as the tongue begins to pry him apart, as his hand takes careful grip of the scooped horn adornments as his ankles crest together over one shoulder. His claspers beg as his spine temples into an arch, giving into the attentive tongue bathing his rear with saliva, his walls clenching out beads of mucus with every slow breath.
"Impatient," Varinc chuckles, leaning back over as they drip oil over their hand.
Renn only grunts, and pulls the skin of his groin taut as the claws coax between his thighs.
Relief sighs between his lips as they stroke against his body, careful in their stride as the tongue returns to his claspers, soaking him once more in saliva as one by one the claws find their way. Pressuring inside him as his tail shivers, stroking him into groans as they quest further, holding him captive as the tongue battles between his claspers. "Fuck," grunts with a groan, hips begging for more.
"Ready?" A whisper, low as fingers find rest as palm knuckles rest against the base of his tail. Giving a full, fulfilling thrust to draw a quivering breath before a final withdraw.
"Let's go," Renn huffs, leaning back onto his elbows.
Varinc guides their erection back between Renn's claspers - almost three times the size. "Try it straight, then turn over for the rear?"
Renn nods. "Sounds good to me." And watches as his legs are guided to sit over the pachy's hip, his own hand guiding himself open as the tip presses at his vulva. "I'll tell you when I'm maxed out," breathes as the tip presses against his walls, guiding him to exhale as the girth pushes his body to properly take. "Fuck," heaves with a grunt, aching as his fists ball against the metal, hands pawing as more of the stern weight eases against his walls, a heavy pressure that draws small sounds as each exhale relaxes his pelvic floor.
"You good?" Varinc purrs.
"Yeah," huffs, "just, forgot how filling you are." A hand pulls through his hair, parting around his spires as his legs squeeze. Pushing back around the girth for more - stomach pressed with a minor bulge as it pushes against his backwall, putting pressure against his stubborn cervix that has moved away from the sloped head. “Give me a couple bumps, think you’ve already pushed against my cervix.” He grunts, gripping around the girth as his claspers drip against his stomach.
With a chuckle, the pachyrsis complies. "Give you an all out stuffing feeling, huh?" Only partly pushed inside, the distance between bodies stressed even as Renn’s ankles try to move them together above the sweeping tail. Half of it lies inside, the other half left unattended even as they withdraw, hips striking carefully to make Renn bounce against the metal with a grunt.
“HOF-fuck,” Renn grunts, taking full grip of his claspers with his secondary hands, stroking them above his pressured thighs and holding them against his stomach. “Yeah, that’s about all of you I can take,” he huffs, leaning upon one elbow. “Let me flip over, let you take my ass.”
Varinc nods, and holds onto Renn's legs as they guide themself free of Renn's body.
Rolling over into his stomach, Renn can't help but watch backwards as he leans upon his elbows as his tail is shoved aside, as the hefty girth of the pachyrsis rests against his ass while another generous amount of grain lube strokes his rear. Fingers pet him as Varinc attends to their awaiting erection, generous in the strokes as oil makes the surface glisten in the shadowing light beneath the engine cone. It's well lubricated size, while resting against Renn’s tail and ass, gives him a great prelude of what is left to come - before Varinc gives Renn a hearty smack on the ass, pulling the mechanic back so his claspers can hang freely beneath the cowling.
Guiding the tail to lie almost over their shoulder, it gives room for both hands to hold at the silivosha’s ass, parting cheeks and tail all at once.
“Easy,” Renn whispers as the glans directs against his muscles, pressure put beneath the base of his tail as his arms hold cross beneath him, fingers prying against skin as he awaits the girth... and gasps as the wet pressure begins to take.
Each gulping exhale relaxes the muscles further as the pressure is kept steady, feeling as the girth swarms against his insides as his hips push against the cowling, his claspers press against his thighs as his own body’s restraint keeps him from comfortably taking back - resistance only temporary as he lies himself still, easing his pelvic floor to relax. His claspers throb with each gentle clench as more eases into his body - his tail flaring back and over his own shoulder as thrusts are made gentle.
Above him, as he takes grip of the ends of his tail, the pachyrsis holds him exposed, pressing their plate maw against his back as their hearty girth begins to completely take. Their breathing is slow as each venturing thrust drives them together, saturating them in the intimate glow as claws push around shivering hips, guiding them backwards so as Renn’s legs hang outside the cowling once again. “Renn,” rattles through their chest as their bodies roll as one - the space cramped as still more awaits to be taken, their bodies shivering with each gentle thrust.
Renn begs back as he leans upon his elbows, overwhelmed by the pressure robbing him of self-control, his feet curling around the pachy’s drifting tail. “A bit to the left, might need to give a few gentle pushes,” he heaves, hips shifting to accommodate. “Be careful,” shivers, gasping as the large pachyrsis thrusts inside him, drawing a shivering groan as it fills his lower body.
“Want me to talk for you, Renn?” whispers as Varinc leans down around him, claws holding hips firm as their bodies grind.
"Yes, please do," quivers as the pachy's girth fills him once more, shifting the pressure to his left side in hopes to take the rest. "Tell me how well I'm taking your giant dick."
"Well, are you?" Varinc teases, taking a full hand of ass once more as they roll themselves to fit, "only got half of me inside you so far. You should work for the rest of it, make yourself absolutely soaking wet until you’re completely around me.” They growl against Renn’s spine, pressing glutes aside to make the muscle taut, a thumb stroking gentle as the silivosha’s tail is pulled by his own hands. Petting the muscle as more oil is stroked against it. “You’ve got such a beautiful ass, too,” draws with a sneer. “I’ll let you ride me out if you manage to make it all fit,” dances between their teeth, plate maw pressing with a groan as the shift meets between them, pressure returns as bodies adjust.
And it's where Renn’s voice is drawn hoarse in a gasp - forcing himself back to his elbows, yanking his tail to hold him exposed as he shifts around the erection to guide it inside his body. Where his body trembles, bucked against the metal as claws hold around his hips, cradling his thrusts as they temper against his drooling claspers. “Little more to my left,” he groans, hips lifting to direct the erection within himself, giving into the sheer length as his body takes it once again, muscles relaxed for the easy movements. “Careful,” he quivers, “I think, almost there.” His shoulders tremble, tail pulled as he presses back.
The shift is gentle - a sudden take that brings them to sigh as muscles hold tight.
“That’s a good boy,” rumbles as their bodies edge to press, plate maw whispering against skin as the thrusts move gentle, putting pressure to insides as a hand pulls around Renn’s throat. “Taking all of it like that,” rolls through their chest, hips hitching as plate teeth kiss against skin, “you should be proud, Renn, you’re so close to taking every last bit of me.”
The teeth roam as their bodies sway, Renn’s hips begging back as his claspers hang firm. "Harder," Renn groans as his hips pressure back, heaving for completion as the hearty thrusts shakes him to his core. As he leans into the hand held grip against his throat, his legs screw and curl beneath them, claspers aching against metal.
Varinc laughs, plate maw drawing against scalp as their hands hold back to Renn's hips. "I thought you wanted to take me gentle, silivosha. Do you want me to take it slow, pressure heavy as you sink around me begging for more - or to be left in absolute ruin." Their breath is heavy with warmth, panted as their hips rock, stomach pressing against tail as the proximal fins grip back against them.
Shivering, Renn presses back around Varinc, a secondary hands reaching to his stomach where the erection drafts a bulge - moving beneath his palms as thrusts knock against his pelvis, pushing his eager dripping claspers against the cowling metal. "Give me it; hard. Firm. I want to feel every millimeter deep inside me," he groans, shuddering as the length leaves him vacant - only to fill him once more. "Fuck," his teeth grit, shaking as hips complete with his own.
A roaming chuckle rolls through Varinc as they adjust, legs shifting as they prop themself against the engine inlet, shoving Renn's tail over their hip to curl against their own. "Oh, I'll do more than that, sweet thing," their pelvis rolls, edging within as space breathes between them. Leaning upon elbows, finding purchase against stomach and hip, their claws splay - taking grip of the leaking claspers. "I won't leave you vacant," whispers plate teeth over spine as their bodies poise.
Aiming. Settling as the pressing bulge is held within a palm, Renn curls an arm around the grip pulling his stomach.
"Do it," the silivosha sneers.
And hips strike into his own, bouncing him along the metal as a gasp holds in his throat, fingers pressing at the echo of the intrusive girth as it tunnels through his body. It pulls him back as he falters to hold strong, muscle already well ached as again pelvis strikes, bring him to groan as claws pull around his sensitive claspers, stroking them as another stride makes through his body, departed with a shiver before a gentle, long, agonizing pressure returns firm.
It pleads noises from him firm as the pachyrsis takes his self restraint, pulling around the echoing throbs as the claspers drip with anticipation, mucus traveled drifting from his unattended vulva. It's paid no mind as the claws continue to jerk, bringing Renn's attention back as each thrust bounces his body from restraint. "Var," a breathless gasp, hips begging back as the erection tunnels through into his guts. "Let me -," mewls as his hands falter to take grip of the pachy's, begging as he squirms beneath.
"Say again?" Varinc growls low, constraining themself. Elbows holding them stable.
“Let me see you,” Renn growls back, teeth bared sharp as he tries to turn around, claspers shrugging against the cowling metal. “Let me see you!” shouts soft, pulling a leg up against the engine metal as drool traces his mouth, sweat staining his compression top as his legs struggle within the confines of his pants. “Ahfuh, please,” his temple presses against the metal, fuming, teeth gritting as his legs coil and claspers rut.
“Hold on,” the pachyrsis grunts, hips leaning back, pulling themself partly free as the silivosah holds tightly around them - almost pushed free before one arm pulls around a thigh, held fast before barreling down once more as fur bristles along their spine.
Each roll brings the huffing groans, the sharp whistling exhale of the pachy’s complex olfactory system as their mouth holds against Renn's chest. It’s where Renn holds them firmly close with one palm grabbing a temporal horn as the other presses against the echo of the prodding girth, gripping as the thrusts remain smooth yet firm; accentuated by each deep exhale warming his chest. Claspers struggle as they rock against the cold metal, mucus slimed with ever pivoting thrust as he tries not to take grip, pulling his arms around the thick neck as his face lies against the skeletal plating with every heave.
Claws take his hands full force.
As a knee catches against cowling metal, his arms are thrust back, reaching towards the quiet engine blades as Varinc takes his mouth.
Forgetting to keep himself muffled, gasps relieving into the mouth cupping his own. Letting the firm tongue graze and kiss, taking it in stride to mute his pleas.
Hips strike firm; his legs quiver.
Shaking as the pachy flares out inside him, as a broad thigh pushes him up back to the cowling metal as his legs curl around it in return. Holding him in place, keeping him steady as bucks move fast, meshing his senses as their noises hit tempo - muffled by their meeting mouths as the pachy's fists curl around his head - claws pleading against wrists until they finally falter. Knuckling against the metal, shoving their weight as Renn grips the temporal horns behind the rearing ears, holding tight as his claspers ache against the metal where it shifts beneath them; onboard struts adjusting to the sudden force, engine tilting downwards to the ever so minor degree as they continue to wallow in their frantic mess.
Fluid sticks firmly between them - messing intimate mucus with sweat and the silivosha's moisture-laden skin. It sticks against the metal as the claspers continue to plead for relief, flexing firm.
Renn gives in as his hips are guided by Varinc’s own, fatigue drawing hips loose as the thrusts begin to hit their peak, gasping as his muscles contract around everything and nothing. His mouth is returned as his breaths are fast and harsh, shivering grunts as the pachyrsis’ head rests against his chest - pressure put as plate teeth take grip of the compression top, gentle in the pull as they chase their own peak.
Tail curling, Renn watches down as he feels Varinc flexing inside him, warmth rising within his stomach with a shallow groan.
Reaching down, he can feel the glans flare inside him; the shallow thrusts that mark the fulfilling warmth that fills his body. “Hofuh,” shivers as he rocks - more than he anticipated, recoiling as the sheer load swarms his nerves. Watching, observing as Varinc releases his top, he arches into the final thrusts marked with deep guttural resounds. "That's so much," breathlessly complains, secondary hands cupping his stomach as it feels swollen. Renn grimaces.
Silently, Varinc rests their head. "You good…?" A brief chuckle, shifting to withdraw. It's a lazy attempt.
"Yeah," Renn grunts. Gasping as the pachyrsis begins pulling themself free. Slowly.
Legs pressing close, he squirms.
Emptied… save for the saturating warmth.
Pulling his hand through his hair, he sighs.
He feels claws against his hips. A suggestion to get down from the engine, to return his pants even as he's still recovering. "Give me a moment," he uselessly barks, avression drained as this mind is still caught up in the mess.
"At least move so I can clean up your loads," Varinc grumbles, forcing Renn to slip down from the engine inlet and to rest on the floor at their feet. "Holy shit did you shoot far," they remark; wiping down the mess of mucus, and the shot of ejaculate angled along the inlet's inner edges.
"Could've gotten it on my top," Renn grunts, accessing himself before wiping himself of sweat and mucus slime. He can't do much about the nausea that begins to take hold. "Right, that gear shaft. Which wheelhousing was it again." Forcing himself into a kneel, he manages to pull his pants back into place. Save for shoving his claspers down a pant leg as they still sting from the exertion. "Let me get another rag, and I can help you wipe down."
Taking pause, Renn stares as the pachy unamused. "Please put your dick away before someone sees. They can see your log through your pants as it is, they don't need it flopping around."
Varinc chuffs with a brief laugh, "as long as you pull those overalls back on, no one will know the wiser."
