The Tilfish romance, smut chapter
An entomologist who found love while employed on Sillis finally gathers up the courage to ask his tilfish partner for sex, finding out that their genitalia is mostly anatomically accurate to that of mantises. The only liberties i took were having a visible streak of exposed membrane on the sides when aroused, females also being lefty or righties while irl it's only male mantises, and having the abdomen get stiffer and more curved with arousal. For how their genitalia looks, refer to the thumbnail.

A blank in the conversation. Usually, swylta is the one to fill up those, but i've wanted to bring it up for a while, it's awkward and embarrassing, but... so is this.
''Swylta, i...'' Feeling myself falter a little as blood rushes to my face, i gather my resolve ; asking this clearly is important ; it's respect, i can do that much for her. ''Before i say it, just... i know how it can feel, so please don't feel pressured in any way, it's absolutely ok if you don't want to, and if it's any kind of uncomfortable, just please tell me and i'll stop. It's just that... we've been together for a while now, and i've just been wondering... if... if you wanted to have sex !''
Holy shit i actually did it.
In the second before she answers, i feel myself getting more tense. It's hard to gauge her reaction before she speaks ; her face is a rigid mask of chitin with pupilless eyes, and besides guessing where they are directing their attention towards via some slight movement of their antennaes, the body language of tilfishs never evolved for social communication. Not that i've ever been all that good at reading it in humans, either.
''i was wondering when you'd ask !'' she chirped, in a kind and understanding, if slightly amused, tone ''...of course i do-''
''N-no, i... please, _please_ think about it. I-i'm sorry, i know it's probably irrational, but i know for a fact that going too fast is just horrible for everyone involved...'' a slight pause. I hope my discomfort at remembering that didn't show. ''So just please think about it, give it an hour or two, an instant yes like that, even if it's there, i-it's too easy getting carried away and saying it on a whim, i don't want to risk that.''
As it does all too often, a sharp pang of realization hits me right as i finish my sentence. ''Wait i- please don't take this as me trying to belittle you, i trust you and your choices, it's just that even still, i don't want to take any risks...''
As always, my explanation is met with a gentle nod, and as i acknowledge that her mind was set from the beginning, i can feel several things starting to build up with each tick of the clock ; elation revealing itself from under my embarrassment, the steady rush of blood from my veins to my cheeks, and slight, muted worry at the back of my mind.
I should probably go take a shower.

Though i expected the answer, i still did ask.
It's one of those ambiances, our otherwise dull and impersonal refugee apartment on venlil prime manages to feel surreal, the air is thick and cool from the rain that should fall soon, and my mind spins in a cocktail of anticipation, joy, and a bit of apprehension, with a consistent clarity throughout it all.
''are you alright ? You're red as a... lobster, was it ?'' she remarks, in a slightly teasing tone that sends a shiver along my spine. Then, with a few movements of her sleek, armor-like joints to close the space between us, she joins me on the bedside, the low, warm glow of the room's lamp reflecting off of her exoskeleton. ''Seriously though, you really made a big deal out of it, and you seem pretty nervous, are you sure you're alright ?''
''y-yes, i'm a bit nervous, but hey, that's normal isn't it ?'' i reply with a small chuckle. It's obvious that she would, and yet it still warms my heart to see that she cares as much as i do. The whole campaign on Sillis was... awful, and yet getting to make contact, and especially to meet her, made it worth it, i think. ''really though, please don't worry, if there's anything, i'll tell you. So... do you want to... uhm... get started ?''
She goes out of her way to nod in response to this, and i start to reach down into my shirt, before thankfully realizing that undressing must have no sensual connotations to her, as tilfishs do not wear clothes, allowing me to hurry with it.
Smiling awkwardly, i quickly pull my shirt up and off, turning it inside-out while doing so, and feel a slight pain as i take off my pants, which had been biting into my waist. Finally, after i fold and put my clothes on the bedside table with as much care as i can muster, off goes my underwear, which was admittedly already strained.
Turning my gaze towards swylta after a moment, i am greeted with a more than pleasant sight ; The tip and upper sides of her abdomen was now crowned with a small, discreet yellowish membrane, revealed only by a curved slit between two displaced plates of chitin. At first, i worry that she wouldn't be fully aroused, but, taking the sight in further, i feel a small pang of pride and reassurance when i notice that it looks remarkably similar to the female genitals of mantids... which means that it would need to be opened manually, i realize with a mix of embarrassment and anticipation.
A small giggle. ''you're staaaaring~''
I instinctively gasp and wrench my eyes away to stare her face, but before i can stutter out an apology, she cuts me off.
''hey, it's alright, i was just teasing you. You seemed embarrassed, so i thought playing off of it would be nice'' Her tone is soft and sincere, sharply contrasting with the smugness of her previous remark ''do you want me to stop ?''
Oh. So i didn't imagine the slight wiggle of her abdomen and change of posture as she said so. ''Oh thank god... but no, i-i actually kinda like it... It's just that seeing it, it really reminded me of the genitals of mantids... it's a species of insects back on earth, i think i told you about them, didn't i ?''
With my confirmation, her voices takes on a confident, impish tone once again ''I think so, they're the ones with the eyes that look like they're always staring at you... and who eat the head of their partners when they're hungry, right ? Well, i'm a bit hungry, but i think i can find a better use for a head... and you look like you're really in need of it.''
As my focus shifts from noticing that she got it right back to the situation, i notice the direction her antennae are tilting towards and wonder if she meant what i thought she did, before quickly getting my confirmation as she moves to face my side and nudge me slightly.
''You said you wanted to get started, right ? Turn around then, if you'd like some help.'' she chitters as she changes her posture, flattening herself onto the mattress and heaving her abdomen upwards with a slight wiggle.
I obediently get to shifting my position, quickly gathering the strength to open my thighs and move to face her despite the stiffness of my body, spreading my left leg onto the mattress while my right still dangles over the edge of the space, leaving the space inbetween filled only by her, and me feeling spectacularly vulnerable.
She closes the small space between us in a single slow, measured step, approaching right up until her head is hovering just above my groin. And i stare at her, wide eyed, taking in her alien beauty as she methodically opens up her maw from top to bottom ; her mandibles are the first to part open, followed up by her maxillae, revealing that the inside of her mouth is lined with a thin yellowish membrane.
The insides of one, two parts brush against the side of my penis one after the other, slick but not quite wet, leaving me to feel the cold air brushing against my member as she subsides, before repeating this cycle. She teases me with practiced motions, playing my instrument like a skilled musician repeating a performance ; one, two brushes, perhaps a tap on the base of my shaft on one or two sides, leaving me teetering over the edge before pulling out, and da capo, return to the beginning.
With each one of these cycles, a little more saliva is left on me, bringing more impetus to each brush, leaving me craving for more in the growing cold inbetween her touch. And as she stops in preparation for the finale, i'm hit by a sudden pang of guilt and shame that themselves bring their own kind of ecstasy, knowing that i won't be able to last ; I can feel my heartbeat between my legs, every second marking a new throb, and my head feels like it's about to explode.
And so, when she finally heaves her head down fully, taking me inside her tight oesophagus as she cradles my member with her labium and labrum, it only takes one single thrust for me to cum.
After her teasing, the climax is intense, and my mind goes blank for a second before i return to my senses and see her recoiling slightly, turning her head towards the sheets ; i'm not sure if it actually was pathetic, but the thought brings a certain backhanded thrill regardless.
''o-oh god i'm sorry i... uh... it's just that-'' she quickly whips back to me and coughs before swiping one of her maxillae on her labium to push out the remaining semen ''Hey, don't apologize, you did great... also, if you want a tip, that's a turnoff for most peoples. I think it's cute, though.''
''Thanks, you... well, that was really great...'' And completely one-sided for her, i realize with little worry and much anticipation as i close my legs and rub my arm ; this is something i can make up for easily. ''It's only fair that i give back right ? If you want me to... d-do the same, i... well i actually really would like to''
''Ah... yes... uhm...'' Surprisingly, her tone is somewhat strained, though still much more forward than mine ''oh, and screw this. This part's always awkward with other species, but it's you, if anything you'd probably be glad to hear that over dinner.''
''Our sheath's composed of two bits, upper and lower, see the wide one?'' She waves towards it as accurately as she can with one of her limbs, and i nod in response ''That's the lower one, it needs to be taken care of first, so stick your hand in there at an angle, move along the curve and then press down. And for the angle, i'm a lefty...''
''oh look at you, i knew you'd like this.'' she quickly adds. The small burst of glee and confidence i felt as my knowledge once again paid off must have shown, but after she says that, she turns around and lowers her abdomen in front of me, now noticeably engorged, more stiff and curved than before, and i get to my task.
I position the tip of my fingers on the lower left edge, and after obtaining confirmation, slide my way within. The inside has a comparatively intense warmth, and while the surface of the plates are dry, they are smooth enough to slide across them with very little effort. I advance slowly, taking my time to explore the sleek curves until the surface i slide across goes from smooth to unmistakably damp and warm, and pull back slightly to avoid pressing on the flesh i may have just reached.
''I-is this the right spot ?'' I ask, neither of us moving an inch ''Yes, and don't worry about it, human hands work a hell of a lot better than paws for that, now press down.''
On her order, i press down with a constant but gentle strength, prying the lower sheath open as it angle downwards, leaving enough space for me to press at the base of the upper one, priming her fully.
I find myself staring a bit too close, able to feel the feel the lukewarm air wafting from it as the prize is revealed ; A slick, smooth membrane, engorged with yellow blood, at the center of which rests one singular hole.
''staring again~'' This time, it sounded more excited than teasing, and she unexpectedly bobbed her abdomen upwards, brushing my face with the lower sheath.
''I'll gladly go down on you, but just tell me if you'd prefer-'' Before i can finish my sentence, i'm interrupted by another bob making her abdomen collide with my face. I think i get the message, and finally shove my head forward into her, cradling my chin into the groove of the lower sheath, and holding the upper one open my propping it onto my forehead, my entire skull caressed by the warmth emanating from her as my mouth connects with her hole.
I suppose it would be akin to a sloppy, one sided kiss, and what i lack in technique, i try to make up for in passion ; i fervently lap at her like a thirsty dog then take more care, trying to make full use of my tongue, straightening it when i tease the edges and widening it when i lick.
What little juices ooze from the surface though lacking odor are slightly sweet, encouraging me to go at my task with even more enthusiasm, which is further added upon by the slight chittering i begin to hear. More sounds soon join this ; that of her slight kicking at the sheets, and her vocalizations that eventually grow loud and long enough for my translator to recognize them as moans.
I turn it off, more aroused by the chittering, and soon move my spare hand to begin masturbating as i pleasure her. The sounds gradually increase both in intensity and rhythm, and what glances i can steal from my sides show always showing movement, until finally she tenses up, and i feel the membrane spasm and constrict, pulling inwards with surprising strength before she moves her abdomen away from my face once it goes still.
''Wew~ that was actually pretty good !'' I stare at her, full of joy and pride, as she moves to face me. ''Really though, i know you were worrying, but that was nice. Also since you asked if i wanted it, penetrative sex isn't really possible for most tilfishs ; our genitalia's made for receiving spermatophores, so with most other species the insertion is too big and it just ends up being painful, plus most aren't as prehensile as our species so it's not very stimulating.''
''I don't care if we can't, that's not a problem, it's worth it just to do it with you ! It's probably silly but i'm feeling really damn proud of finally giving back to you...'' With that, we both approach eachother for one final hug. Me warm and soft, her lukewarm, smooth and rigid, me offering a two-armed embrace, her giving back three times that, and we kiss, my cheeks embraced by a set of mouth parts as i close my eyes and try to reciprocate as best as i can in her tongueless mouth.
The tension being too great, i let one of my hands slip from the hug to finish, earning a pleased giggle from her, and with both of us spent... or, most likely me spent and her satisfied, we slip under the sheaths- no, sheets, and drift off to a quickly found sleep.
