(((This is a smut fic involving two members of my original species, Mothim. Information is below, but, basically, females carry the eggs for a short time before laying them in the male’s pouch. Eggs are ready to fertilize at different times, and can be fertilized either while in the female, as they’re placed in the male’s pouch and he orgasms, or by another male while they’re in the male’s pouch. Carriers are the owners of the pouches, bearers are the producers of the eggs.

Shiir is the equivalent of early 20s. He’s a young adult who has decided that he’s ready to carry for the first time, and, as such, has gone to a more experienced bearer. 

Nanur is more like mid 30s, so definitely mature but not quite past reproductive age. She’s done this sort of thing quite a few times, it’s very common for Mothim. It’s partly because she’s good at being calming, partly because she tends to have medium-small clutches with relatively small eggs, and just a little bit because she finds young, eager, flustered carriers to be absolutely precious. 

Male Mothim are almost all rather timid, and the transferring of the eggs can be a fairly overwhelming experience, so first-time carriers usually go to an older bearer who’s experienced enough to make everything nice and calm. It’s not pressured, they can pick someone their own age if they’d like ,but the potential stability tends to be reassuring. 

There has been some discussion beforehand, some guidelines and a description of what to expect.

So! This is oviposition smut, clearly, and I somehow managed to get exactly 4444 words of it. Also some oral, and a more “standard” sort of sex to start off. Some nervousness at first from one party, but both are very, very willing. Soft-dom gal on top, wriggly, eager sub boi quite happily bottoming. It’s kind of cute, and I tried to not write it extremely fetish-y. Nothing wrong with that, of course, but I was shooting for “cute smut that happens to include ovi” rather than “ovi fetish smut”, and I think it worked? 

Regardless, if alien anatomy, oviposition, and/or inexperienced-but-eager partners aren’t your thing, you should probably read something else. If they might be your thing, come read this.)))

“Come in, little one… no need to worry.”

Shiir crept a bit closer, shutting the door behind himself,
and hesitated for a moment before slinking into the nest that had clearly been
made for this purpose. Fidgeting slightly, he settled into the cradle of it as
much as he could, antennae twitching as he tried to coax himself to shift onto
his back. It really didn’t work, though. “Oh, I’m- sorry, sorry, just- just a
bit nervous, y’know?”

Nanur purred softly to Shiir, moving slowly so he could see
what she was doing, and sat down right in front of him. “Of course. Believe me-
you are far from the first, sweet. No need to worry, we don’t need to jump
right into anything. We get you to relax first,
then… see what we can do. Smell, little one, breathe deep… have something
to eat.”

As she spoke, she offered a bowl of soft fungus-flour buns
with one hand, stroking Shiir’s arm gently with another as she settled down
right next to him and curled gently against his side. “No rush, sweet Shiir. We
get used to each other first, let body and mind relax. Let the smell sink into
you, it will relax you. Remember- it will not force you, I will not do that, it is only to help you settle. You
can still say ‘no’ at any point, and you will be heard.”

Shiir accepted one of the buns, leaning slightly into her
and pricking his antennae to get a better scent of the… admittedly very
tempting smell wrapped around Nanur. Pheromones, he knew, given off by a heavy
bearer to help attract a mate. And he could feel
the weight of her belly against him, heavy and warm with eggs, which was a
beautifully arousing thought. That was what he was here for, after all. He was
here to… oh.

Suddenly eager, Shiir stuffed the rest of the bun into his
mouth and chewed quickly, then turned onto his back- and immediately covered
his face with his hands in embarrassment. “Oh- oh goodness. Sorry, I’m- oh, I’d
really like to- please understand, I want
you, it’s just- I’ve never- I’ve never done
this, you know, and it’s- it’s a bit scary, really, even though- even
though I know you won’t hurt me.”

Nanur pressed a bit closer and tucked an arm over Shiir, but
made no effort to get on top of him or pin him, just hugged him softly and
continued to purr. “Of course. I understand completely- you are far from the
first new carrier I’ve had. It’s a big thing- of course you’re nervous. Just…
relax. And tell me, sweet… would you like me to help you relax a bit further?”
she asked quietly, sliding her secondary hand down to touch Shiir’s inner
thigh- just near the tip of the slick pink shaft starting to become visible. “I
can ride you, little one- we would both very much enjoy it, I imagine it would
help you relax, and it will keep your shaft from getting in our way later. What
do you think?”

When Shiir responded by nodding
furiously,
Nanur purred and scootched down a bit, hooking one of his legs
over her shoulder and nuzzling into his crotch. “Mm, good. Come on up.”

Slipping her tongue out in a fairly lewd gesture, she
grinned up at Shiir, then slowly lapped around the emerging tip of his shaft.
Sliding one hand up to gently spread his slit open wider, she licked around the
inside of the slit, then up his shaft as it stiffened to full length. A pause
to twine her tongue with his cock, demonstrating the flexibility of both, then
she mouthed softly at the tip and purred louder.

Eyes wide and antennae fanned as far as they’d go, Shiir
gripped at the cushions around himself with all four arms, legs kicking
slightly as he whined in pleasure. “Oh- oh,
Nanur, that- that feels- wow, oh,
that’s- okay, that’s- that’s really good, but I’m- you’re- more, please? Can- can I- oh my.”

Much to Shiir’s delight, Nanur let go of his cock for just
long enough to push herself up and straddle him, spreading herself open with
two fingers and pausing to give him a good look. Soft pinkish-red folds
surrounded by thick grey fur, giving off a mouth-watering scent that would have
had Shiir asking for a taste if he wasn’t so very aroused. As delicious as she
smelled, he’d rather have her around his cock than against his tongue-

And, to his utter delight, that’s what he got. Nanur lined herself up, then sank down onto his cock in one smooth motion, drawing a shaky
cry of pleasure from him.

Swaying her hips slightly, Nanur settled until Shiir was
sheathed fully in her, purring gently to her partner. “Relax… feel what you are
pressed into. Those are the eggs I am going to fill you with, Shiir, and I want
you to think about that as I ride you.”

Grinning as Shiir whined softly, Nanur rocked her hips a few
more times, letting Shiir properly feel that the tip of his shaft was nestled
up among the eggs cradled in her belly. That was what this slit was for,
allowing a mate to fertilize whatever eggs were ready for it. Not that it would
matter much this time, since all the primed eggs would be fertilized once in
Shiir’s pouch, but it was certainly helping him to relax. And to start making
the soft, blissful chiming sounds Nanur had been waiting for- such a sweet
little thing! Now… could she get more sounds out of him if she kept talking?
Time to see.

“Oh, so lovely, little Shiir… that’s it. Let me hear you. I
want to hear you moan in bliss for me, little one- and I want you to keep
thinking about what we’re going to do next. I want to see the anticipation on
your face, sweet, oh- let me hear you,” she crooned, leaning forwards for
support, and braced herself with her arms on either side of his frame as she
rocked back against his cock. Slow and gentle, then just a bit faster, purring
encouragement to him- especially as he began to thrust up into her. “That’s it-
good! No need to be gentle, I can easily take you thrusting harder- ah, there, like that again? Oh- good
boy. Just like that, good, so good.”

Leaning down and just bracing herself for Shiir to thrust
into, Nanur lowered her head to whisper in his ears, purring in her very best
dom-voice that usually made carriers squirm.
“I can feel the tension in you, Shiir- let go of it, all of it, cum inside
me, that’s it- ah, yessss.”

She couldn’t feel him cumming as clearly as she would
without a full pouch, but it was still a lovely burst of tingling heat, and Shiir
keening up at her as he thrust one
last time was almost as good. Sliding against him in almost a rutting motion,
she gently moved up and off his cock, then straddled his stomach and waited for
him to get a proper look at her.

Flooded in sensation, Shiir hadn’t realized what the
slick-smooth feeling against the tip of his cock was until she’d pointed it
out, but the very thought had sent a spike of arousal straight to his gut.
Which was probably why he’d cum… sort of embarrassingly loudly, squealing something
resembling her name at the top of his lungs as he bucked up into her. She- she
didn’t seem to mind, though, which was…

Oh, hey, she’d better than not-minded. Smiling as the
purring registered against his fogged brain, Shiir wriggled gently underneath
Nanur, looking up at her with soft eyes. She was pretty. Paler colors down her front and sides, soft eyes, pretty
fanned antennae… and, oh, starting to get bare patches down her forearms. Shiir
still had almost all his fur, aside from a couple of thinner areas on his arms,
but hadn’t rubbed any spots enough for them to stop growing fur back. That took
some time. Started on the forearms, moved up, then onto the chest. Forearms
only meant she was older than him, mature, but not starting to age past prime
fertility yet. Which was… why he was here, and…

Oh.

Oh.

Shiir’s unfocused gaze had drifted down her frame as
everything had registered, and he was now looking at… at the source of the damp
spot on his stomach. His own shaft had retracted by that point, but hers was
starting to emerge… and it was considerably, alarmingly larger than his.
Slanting downward enough to rub against his stomach, slowly dripping a sweet-smelling
lubricant into his fur, and thick. Probably
about as thick as his wrist, and that was just the tip. Which… was…

“…uh… Nanur? Are- are you… sure this is- is going to fit?”

And there was that nervousness again. Nanur purred soft and
deep in her throat, reaching down to take his hands in hers, and guided his
fingers to the tip of her shaft. “It’s all right, little one… we will go slow,
and, yes, it will fit. Your pouch entrance will stretch more than enough, with
some care. Here- touch. Inspect me all you want, sweet- you can fit your
fingertips inside, if you want.”

Nervous fingertips flirted with her shaft for a moment, then
Shiir glanced up and slowly pressed one finger inside, drawing a quiet croon
from Nanur as her shaft extended fully. It was no wonder new carriers tended to
be nervous at first- ovipositors were fairly impressive at first glance, and
hers was no exception. Easily as thick as her small partner’s forearm and about
two-thirds as long, ridged all up and down its length, with something like a
frill just over halfway up. The slit at the tip was wide enough to easily fit
two fingers into, and was dripping lubricant slow and steady against his belly
fur- normal for a bearer about to lay. The fluid around the eggs was slick and
nutrient-rich, it would make an excellent source of additional lubricant, and
it would help to feed the eggs when they were in place.

For now, it was mostly good for letting Shiir get his
fingertips into her shaft, which seemed to be, if not calming him down, at
least fascinating him enough to help him relax.

Eyes wide, Shiir rubbed softly at the inside of Nanur’s shaft for a moment, then trailed both hands up
the length of her shaft to squeeze around the frilled area. There was some give
to the shaft, now that he had his hands on it- still stiff enough to support
its weight, but angled downward slightly, and softer than his shaft. Which made
it considerably less intimidating than if it had been stiff everywhere- that
might not have been so much fun. This? This was still intimidating, but…

Well, Nanur had promised not to hurt him, and was more than
living up to that so far. She was gentle, moving slowly despite the arousal he
could feel building, and she let him explore everything. Clearly, she knew what
she was doing, and was trying to make this good for him. So… if she said her
shaft would fit, it would fit.

And everything still smelled amazing.

Fidgeting slightly in place, Shiir cupped Nanur’s shaft-head
between both primary hands, lowering both secondary hands to part the fur
around the pouch entrance on his lower stomach. “I’m… o-okay, I’m ready. And I-
I want you, Nanur.”

Nanur purred soft and deep down at him, then moved down to
sit between his legs, brushing her fingertips softly over his secondary hands.
“And I want you, sweet Shiir. Relax…
let me take care of you. I am going to stretch you open, nice and slowly, then
I am going to fill you up- first with myself, and then with my clutch. You…
just relax and enjoy, understand? Good boy.”

Continuing to purr to Shiir, she ran both hands around the
tip of her shaft, slicking her fingers up, then stroked them gently around the
lips of Shiir’s pouch entrance. His body would start producing slick soon, but
extra lubrication never hurt, especially with new carriers. Plus, his antennae
quivered at the sight, and he whined beautifully
in arousal.

The outer lips of Shiir’s pouch were a typical deep pink
with little splotches of dark grey, and the next layer were a softer pink now
flushed with blood. The outer lips stretched easily, and the inner lips spread
under her carefully stroking fingertips, granting entrance to the myriad soft
folds lining his channel. “So pretty… you feel this, Shiir? Watch my hands- see
my fingers sink into you. These folds here will help to trap my fluids insides
of you, and, when you are full, they will expand and keep my eggs inside you.
For now… they will help me to bring you pleasure,” she crooned, running her
fingertips carefully between two layers of folds, then lifted her hand to lick
her fingertips and get a taste of his slick. “Lovely Shiir… tell me, have you
played with your channel before this?”

Shiir, for his part, was hiding his face behind all four
hands. He was peeking out, though- watching Nanur, as ordered, and whimpering softly in pleasure as she spread him open.
Speaking was an effort, especially answering a question like that, but- oh, she was being so good to him, he should make an effort in
return.

“I- oh- yes, I-I
have, some, but- mostly around, never inside,
never quite- quite wet enough,
but- oh, wow, that’s… that’s not really a-a problem now, huh?” he whispered,
legs twitching against her sides, and twitched his hips tentatively up against
her frame as he tried to figure out how to move against her. He’d been more
interested in playing with his cock than his channel most of the time, but, oh, this had him very much reconsidering
that preference.

Lifting his head slightly to get a better look, he watched in
fascinated arousal as Nanur spread his pouch wide- wide enough to fit all four
digits into him with no difficulty. Which was very nice to watch, but he was feeling far too aroused to just
watch, and the stretch to his channel was starting to feel more like teasing
than true stimulation. As nice as she was being, he was about to ask for more,
had his mouth open to ask-

And then his voice abruptly failed him (in an embarrassingly
loud squawk) as she curled her fingertips past a particularly narrow set of folds
and just barely into his pouch itself.

Nanur chuckled softly at the response, then leaned down and
gently moved up Shiir’s frame, grinding her shaft unashamedly against him as
she did. “There we are… that’s what I want to hear. Now… are you ready, Shiir?
Yes? Oh, you do look ready… good, good boy. Relax.”

Shiir was beautifully relaxed, and Nanur easily hooked one
of his legs around her frame, supporting his hips with both primary hands and
carefully spreading his pouch with her secondary hands. Purring soothingly, she
lined herself up and rocked her hips in one smooth motion, pressing the tip of
her shaft inside. Dropping the purr low into her chest, she arched over Shiir
and slowly, slowly thrust in further, savoring his gasps and moans as the myriad
ridges along her shaft dragged over his inner folds. “Yes, good, good boy- so tight, so lovely- moan for me, sweet.”

He did, and she lingered for a moment, then thrust deeper-
and snarled softly in pleasure as she felt the frill on her shaft slip through
his deepest folds and into his pouch. “There, Shiir- feel that? You’re spread
beautifully around me, and that was
my frill –nnh- slipping inside you. And… now that the pressure of your lovely,
tight channel is no longer around my frill, it’s going to expand, and that,” she punctuated with a quick
little thrust, “will lock me inside you. How do you feel about that?”

Shiir’s legs kicked around Nanur’s frame with every new
movement, back arched, moaning every time she moved. He’d never been stretched like this, never been
penetrated by anything thicker than his own fingers or another male’s cock, but
now-

Now there was a beautifully thick shaft spreading him open,
ridges dragging over his inner folds, sinking into him until the frill slipped
through the last set of folds and into his pouch itself. Gasping, Shiir braced
himself against the nest and arched against
Nanur, then shuddered, moaned, and went almost completely limp- aside from
keeping his head lifted enough to watch her.

Far past being coherent enough to speak clearly, he could
only whimper at the question, but the
rippling tightness of his channel around her shaft made his meaning very clear.
Yes, yes, please-

And he got what he wanted. The thick frill unfolded and
expanded inside him, locking them together as firmly as if it was a canid’s
knot, and Shiir whined a soft, high note of pleasure up at Nanur as he squirmed
against her.

“Nnh… good, good boy,” Nanur purred, curling forwards
slightly, and purred once more before shivering and going almost completely
silent. “You are such a lovely, sweet thing, Shiir. Now, you need –hhn- to
relax, all right? First- first few are a stretch, just relax, let it happen-
feels amazing soon. Ssshh- nnh-“

Antennae fluttering as a powerful rippling motion shuddered
down her frame, Nanur supported herself with both primary arms, gripping his
frame with her delicate secondary hands to help keep him still and hopefully
relaxed. With her ovipositor locked into him, her frame was signaling that it
was time to lay, and she had no reason to fight the urge.

The first egg, as always, was a bit uncomfortable. The
stretch straddled the line between pleasure and pain, and, judging by Shiir’s
expression, the experience was the same for him. A bit strong, a bit much- and
then it slipped into him, the weight registered in his pouch, and a quick gush
of fluids followed.

Shiir whimpered uncertainly and kicked out reflexively as
his channel stretched uncomfortably wide, but shivered and moaned as the egg
settled into place. “That’s- I- oh! Not- not so bad, not reall- oh-“

A gush of wet heat followed the egg, drawing a shuddering
moan from him, and the stretch started up again as the next egg pressed against
the first set of folds in his channel.  This
time, it was a bit easier, a surge of pleasure pressing deep into his frame
with only a twinge of discomfort, and the third egg brought nothing but pleasure
with it.

Shiir had never played with filling his pouch before. He
knew some people did, even before their first clutch, but this- this was new,
and it was amazing. And it didn’t stop!

Somewhere around the sixth egg, his vocal cords just gave
out, turning his shaking squeals into nothing but pants and whines of pleasure.  Not that he was in any shape to mind, not with
his pouch being slowly stretched open by the steadily increasing weight of his
first clutch, with Nanur purring and stroking his fur as she filled him up-!

Nanur had done this enough to stay mostly coherent, which
was excellent for her, since it let her enjoy the sounds her sweet little
partner was making. He was just so sweet! And first-time carriers, oh- always
so easily flustered, so very delighted to be filled like this. They moaned so wonderfully, it was delightful!

And to feel the swelling of a slender belly gradually
filling with life, the tight channel squeezing firm around her shaft, the
warmth and the deep pleasure of knowing her clutch would grow well inside him- maybe
the pleasure was based in instinct, but that didn’t make it any less amazing.

When the pressure in her belly had eased to about halfway, her
voice started cooperating again, and she took full advantage of it. “Oh, sweet
Shiir… so warm, so beautifully tight.
You are going to be so very full soon…
and you are already rather full, aren’t you? Already stretched- and I know you
can feel it. So lovely. Now- halfway through. Still good?”

She could probably have managed to stop if he’d needed to.
Not for good, and he was tight enough that she wouldn’t have been able to pull
out, but she could pause for a moment longer. Shiir, however, firmly
discouraged that idea by squealing a word that was barely recognizable as “more” and thrusting up against her,
hard, his eyes locked on his own stomach as his pouch filled. So Nanur purred,
rocked her hips in one smooth motion, and let herself go.

Shiir had tried to count for the first few eggs, but had
quickly lost both his count and his desire to keep track. After that pause, he
lost everything but the sensation of bliss,
of Nanur curled over and around him, and the cultch steadily filling him.
With no reason to resist, he let himself get lost in pleasure, losing track of
everything but sensation.

The thing that brought his awareness crashing back was a
flood of liquid deep inside him, like what came after each egg, but much
larger. Nanur was shuddering around him, keening loudly for the first time, claws
wrapping tightly into his fur as her hips rocked against him. A moment of
pleasure as Shiir registered what was happening, that this must be what orgasm looked like for bearers, then-

Then the pleasure from the stretch, from the warmth, from
the thrusts became too much, and
Shiir squealed his bliss as his frame tensed, as something deep in his belly
tightened and pulsed, adding a final
fraction of liquid pressure to his stretched belly- and that was it, he was
gone.

When he finally started to come back to himself, it was to a
gradual awareness of Nanur stroking his sides and belly, purring to him.
Blinking a few times, he flicked his antennae and churred inquiringly, lifting
his head to look down- and bushed under his fur as he saw that they were still
joined. “…oh. Goodness,” he squeaked, blinking up at her, “that’s why people
like that.”

Chuckling softly, Nanur lifted a glass of water and held it
to Shiir’s lips, crooning encouragingly until he drank. “That… and many other
reasons. Relax, sweet. I can pull myself out now if you need me to, but it will
do better if I stay inside you longer, keep everything inside. The fluid you
felt is rich in nutrients and will help the eggs to bind to your inner walls,
and it will help your fluids to
spread and reach every egg that is ready for you.”

A soft stroke to his stomach, then she glanced back up at
him, her voice soft and quite happy. “Now… that
was about twenty eggs. A good sized clutch, but not too big- and the eggs
not large, either. Should be comfortable for you, but the weight will take you
some time to get used to, so- settle, sit, drink. When you feel steady, eat. I
have already- you need to as well. How do you feel?”

Shiir obeyed, drinking and listening (and blushing, goodness), then reached for
the buns he’d put aside earlier. “Um. Yes. I-I feel…”

A shaky wave of both secondary hands, then he shrugged, took
one of the buns, and stuffed about half of it into his mouth at once. “I feel yes.”

 


Murmuring “fair enough”, Nanur curled softly against him,
nibbling at another of the buns. It was hard to have much of an appetite when
your guts were shifting back into place, but she’d burned enough energy to be
hungry nonetheless, and it was best to set a good example. Shiir looked a bit
dazed- but very happy, probably drunk on endorphins more than anything. Quite
lovely to see, and he smelled very nice.

Gradually, she felt Shiir’s channel starting to tighten
around her shaft, which did get a bit
less than comfortable after awhile. Humming reassuringly, she began to move her
hips in small, easy motions, pulling out gradually so as not to overwhelm
Shiir. “Feel? your body is beginning to settle around your new clutch. Folds
will swell to fill your channel at first, keep all the fluids in, then relax
just enough for another carrier to get inside you. Highly suggest you try soon-
seems to feel amazing. Many lovely sounds- like you were just making.”

Shiir wiggled and squeaked at the odd sensation, eyes wide
and antennae perked, and blushed as he watched the gush of fluids that escaped
along with her shaft. “Nnh- oh. Wow. I- wow, just-“

Carefully, he sat up just a bit, cupping his stretched pouch
in one hand and his pouch entrance in the other. “Oh. Doesn’t… doesn’t hurt. At…
at all. Lots of stretch, but… huh. I guess… fluids? And-“ a bit of shaky hand
waving “-and the- you know, the, um- fun.
I’m… wow, can- can I just… close, please? Hold-“

A bit incoherent, but he got his message across, reaching
for Nanur until she curled up next to him. Once she was settled, he cooed
quietly in pleasure and shut his eyes, antennae fluttering in something like embarrassment
as he felt her stroke his stomach. No wonder she liked this, but- oh! This-
this was his clutch now, wasn’t it?
His.

His.

Purring reassuringly as Shiir succumbed to a bout of
flustered giggling, Nanur curled around his smaller frame, wriggling until she was
almost underneath him. “Ah- I have missed this, I like to be under others
sometimes. Now- rest. Sleep. After you sleep, we bathe, then take you home-
with more food, must give you plenty of energy.”

Stroking Shiir’s back and sides until his eyes drifted shut,
she purred and watched and lingered awake for just long enough to be sure he
was out, then drifted off as well. Later, she’d take him to a spring to clean
away any escaped fluids, escort him home while he re-learned how to keep his
balance, and- hm, probably take the ingredients to bake something for him, he
seemed quite taken with the buns. Best thing to do for someone going into the
work of carrying your clutch- feed them. Especially the younger ones who might not
expect to be as hungry as they were.
