(((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.

Soundwave decides to take advantage of an empty ship to have some fun in Megatron’s throne, Megatron walks in and finds him, a considerable amount of fun ensues. 

Loosely TFP, but with Megatron actually sane and a decent person. This is like good-ending TFP, basically. No significant warnings. Improper use of data-cables, some awkwardness and general embarrassment, and relatively minor fluid stuffing with a biological basis- i.e. overflow tanks are a thing in Cybertronians and get full when you have a larger-than-you partner. Spike-in-valve smut, little bit of showing off, gets a bit fluffy. Definite praise kink somewhere in there. 

Soundwave very rarely got any time to have the ship to
himself. But, with everyone out on reconstructive efforts and attempts at
socializing, he was left mostly alone. Which meant he had the throne room to
himself for non-urgent reasons for once, and, mm… he had plans.

Plans which were turning out to be a lot of fun to work on.

Nuzzling into the back of the throne, Soundwave rocked his
hips and spread his thighs wider, inhaling deeply to fully enjoy Megatron’s
scent. Strong, powerful… and stil warm. Which made it easier to imagine that
the datacable he’d wrapped around his own frame was the pressure of strong
servos on his hips, to imagine that the cable slooowly pressing into his valve
was a thick spike. Good, good- but not quite as good as the real thing. Which
he should stop thinking, he wasn’t going to get that, and- ah!

Mmh, nice- that was a sensitive spot. Soundwave exhaled
slowly and rocked his hips down again, taking the cable a bit deeper, and
curled the tip slightly to rub against that spot again. Ah, yes- that was good.
Of course it was good- Megatron was an intelligent mech with plenty of
experience, he would know how to find the right spots.

Helm lolling back, Soundwave panted and whined softly, valve
clamping down around the cable, starting to relax completely-

And immediately went incredibly, painfully tense as he heard
the door slide open. Pit- slagging pit- he’d
locked the door! He’d definitely locked- and oh, no, there was only one other mech who had the codes to unlock that
door, and that was-

Curling into himself in embarrassment, Soundwave hunched his
shoulders and tried to pretend he wasn’t there, whining in mortification as
Megatron approached him.

Megatron slowly walked up to his occupied throne, brow
ridges raised, and paused for several long moments before speaking. “…well
then, Soundwave,” he began, then smiled slightly and moved to put himself where
Soundwave could see that he didn’t appear to be upset, “are you enjoying
yourself?”

…yes. Soundwave nodded slightly, once, hunching his
shoulders even further and hiding behind the flat of his arm. Pit- this was
mortifying. He’d been caught pleasuring himself on Megatron’s throne, clearly
thinking of Megatron, and still had the cable pressed into his valve- mostly
because it would hurt to yank out at this point with how tense he was. This was
not how he’d wanted to express his
interest, this was embarrassing- but,
yes, he had been enjoying himself.

Megatron slowly reached to stroke Soundwave’s arm, coaxing
the spymaster’s servo down away from his face, and pulsed a field full of soft
reassurance to the flustered mech. “Well then… my apologies for disturbing you.
Now… I have a question, and you are free to think before answering. Do you want
me to leave so you can continue enjoying yourself here, or do you want me to
join you? I am open to either option… though I confess I would prefer the
latter.”

Firmly meeting Soundwave’s optics, the former warlord slid
one servo down to touch Soundwave’s narrow claws, trying to ease their tight
grip on the edge of the throne. “Please understand, you are under no obligation
to let me touch you. Easy- you know me, Soundwave, you know I would never hurt
you. And you have my word I will leave if you ask. So… with that in mind…”

Purring gently, he loosened Soundwave’s servo and lifted it
to his lips for a soft kiss, trying to charm the nervous mech into relaxing.
“Do you want me to join you?”

Oh.

Yes. Primus, yes, absolutely. He couldn’t see why Megatron
would want him, given how many mechs
would more than willingly berth
Megatron and had expressed their interest in the past, but… oh, if Megatron
wanted this, absolutely.

Soundwave nodded slightly, optics wide, and slowly turned to
face the larger mech. He… wasn’t certain how to start here, but yes. Please.
Because he trusted Megatron- he knew his Lord wouldn’t hurt him, would never
hurt anyone like that, but especially not him.

Megatron held Soundwave’s servo gently between his own,
engine purring in approval, and slowly moved to stand in front of his throne
where he could look Soundwave over. “Thank you, Soundwave,” he purred, his tone
as soft as he could manage, not wanting to spook the still-tense spymaster into
running. Poor mech didn’t deal well with embarrassment, he was shy. Time to
reassure him.

“Let me be clear, Soundwave. You are allowed to refuse at
any time, and I will not be upset if you change your mind. If you are
uncomfortable at all or have a request, please
tell me. Anything you want, I will be delighted to oblige. Am I understood?”

He waited for a nod, then purred softly and leaned down
slightly, projecting interest/arousal/reassurance
to the pretty spymaster in his throne. “Good. Now- turn around, Soundwave,
get comfortable, and slowly pull that cable out of your pretty valve. Let me
see you. The rest of you is so lovely… I want to see what your equipment looks
like.”

Oh, Primus. Optics
dimming slightly, Soundwave nodded and slowly turned around, optics flicking
between Megatron and the floor. Shy, he eased his thighs apart and glanced up
at his watcher, biting his lip, then slowly eased his data-cable out of his
valve. He’d… never done anything like this for an audience, but the way
Megatron was looking at him made fire curl in his belly and wrap up around his
spark chamber. That was- oh, Primus, admiring.
Lustful, yes, but not threatening, not
like he wanted to take something- like he was delighted that Soundwave was
willing to give him this.

So he let Megatron see his valve, then he took it one step
further, wrapping the lubricant-coated cable around his thigh and pulling his
legs apart. He could feel himself
blushing, but Megatron purred in
approval, the sound drawing a flutter from his spark, and… oh. He wanted more
of that.

So, shy but more than willing, he lowered a servo and spread
his valve lips open with two careful fingertips to show off the lights.  

Pulsing stronger approval/arousal
to Soundwave, Megatron stepped closer and gently slid his servos around the
spymaster’s frame, lifting very gently to start shifting him around. “Oh, such
a beautiful mech. So, so lovely, and so smart.
Whatever made you think I wouldn’t be interested in you, Soundwave? You are
gorgeous, intelligent, and charming,” he
purred, then chuckled at a questioning little glance. “Yes, you heard me,
charming. In your own, precious way. If you had asked me, I would have very gladly accepted, just like now.
Here… let me get you comfortable. Just relax for me.”

Soundwave was light, and it was no effort whatsoever
for Megatron to lift the lanky mech enough to sit down where he had been a
moment ago. He could feel Soundwave quivering
against his servos, tightly coiled field buzzing anticipation/excitement/intrigue/arousal/nervousness against Megatron,
but the spymaster was moving with him and there was no fear in his
oh-so-expressive optics. Maybe a bit nervous, but clearly willing, exposed
valve radiating heat against Megatron’s plating as they settled into place.

Engine rumbling soothingly, Megatron set Soundwave in his
lap and stroked the spymaster’s back with one servo, gently splaying those
gorgeous thighs around his hips with the other servo. “There we are, Soundwave.
Comfortable? Good. Now, beautiful… I would like to spike you. You have such a
pretty valve, and… I imagine that’s what you were thinking of, hm? My spike in
your valve? I confess, I very much hope so, because…”

Pausing, he gently palmed one of the spines along Soundwave’s
back, rubbing it between his fingertips in a fairly suggestive gesture as he
purred his desires to the gorgeous mech in his lap. “I want very much to feel
your valve around my spike. I want to see you in my lap, want to see you in
pleasure… I want to watch you ride my spike and take your pleasure with me. I
am open to other suggestions, but… what do you think of that?”

Okay. Soundwave
nodded quickly, then whined quietly, flustered, and pushed his face into
Megatron’s shoulder to hide. Yes, yes- absolutely. That was his exact fantasy, Primus- him in Megatron’s
lap, riding his Lord’s spike, in control-
Primus, he wasn’t about to refuse that. Especially not combined with
reassurance. And praise, Primus take
him now, Megatron was praising him
and it was sincere. Soundwave knew
the voice that Megatron used to flatter others, and that wasn’t it.

…other people didn’t get this turned on by praise, did they?
Because he knew praise kinks existed, but this was unfairly hot and was making it very difficult to focus. But, for
this, he would try.

Settling his frame against Megatron’s, Soundwave slowly
rocked his hips against the larger mech’s, breathing a quiet sigh of pleasure
as he rubbed his valve over the heating pelvic plating under him. Without his
cable spreading his valve open, he felt empty,
and he wanted something. Specifically, he wanted Megatron’s spike inside
him. As close to now as possible. Giving a quiet, pleading warble, he ground a
bit harder against the closed panel, trying to coax Megatron to-

Oh dear.

Megatron shifted before opening his panel, making sure that
his pressurizing spike wouldn’t end up pressing too hard on Soundwave’s valve,
and cupped his servos against the slender mech’s aft for support. He’d felt
Soundwave twitch away from him, and he could understand why- his spike would be
a stretch for someone close to his size, and Soundwave had lanky hips.

Careful not to trap
the spymaster, he rubbed gently at Soundwave’s lower back with one servo,
slowly easing the other down his aft until he could just touch the lower edge
of that pretty purple valve- a soft tease. “Easy, Soundwave. You have nothing
to worry about- we can go as slow as you need. I will not cause you pain, I
promise. Here- rub against me first, see how I feel against you. Figure out if
we need to stretch you open further before we proceed. And- listen. If you do
not think you can comfortably fit my spike, we can do something else. We are
both clever mechs, we can come up with alternatives. See how you feel, then let
me know.”

Relaxing again at the reassurance, Soundwave settled back
into place and looked down at Megatron’s spike, slowly wrapping a data-cable
around it to feel it out. Unsurprisingly, it was fairly large, wider than
anything Soundwave had taken so far. But… not by too much, and, unlike his
cable, shaped to fit a valve. And there were a series of ridges along the upper
edge that he… rather wanted to try out. So… a large spike, yes, but-

Well, the thing that helped make up his mind was that it was
attached to Megatron. Megatron, who would never hurt him, was purring
reassurance to him and rubbing his back and waiting
despite the growing arousal in his field. This was safe- just as safe as
playing with a toy back in his quarters, except with Megatron. Which was delightful, not just for the warmth and charge
and sensations, but for the praise and
for the mech he trusted, the mech he adored,
holding him close. Primus.

So he took the offer. He could do this- he could take
Megatron’s spike, absolutely. Or- at the very least, could do something with it, something to bring
them both pleasure.

Optics on Megatron’s face, he lifted himself up and slowly ground
his valve against that impressive shaft, panting softly in arousal and
anticipation. And, oh, already an
improvement over his toys, because there was charge jumping between them as he
rocked against Megatron, and because his Lord was purring in pleasure against him.

Lowering his data-cable to wrap around just the base of
Megatron’s spike, Soundwave carefully lined himself up, then rocked his hips
down in one slow motion. He was wet enough that it was an easy slide, the tip
of that pretty spike slipping easily into his valve, and he paused like that to
consider the sensation before offering Megatron a nod and a tiny smile. Yes- he
could absolutely do this. Might need some time, but he could. Could absolutely
do this… just lower himself, nice and slowly, and stop if he had to.

Optics dimming, he settled against Megatron’s frame and
purred softly, unfurling his field to purr bliss/arousal/anticipation
to the larger mech as he started to press down further.

It took more than a little effort for Megatron to stay still
as that hot, tight valve started to wrap around his spike, but he managed it.
Mostly because he absolutely refused to buck into Soundwave, not with how tight
the spymaster was. No matter how teasing it got, he was not going to risk making Soundwave even slightly uncomfortable.
Besides, there were nicer things to focus on right now.

Whispering “that’s it, be gentle with yourself”, he cupped
one servo against the side of Soundwave’s helm, pressing his thumb to deep blue
lips until they parted for him. Sharp dentae gleamed in the light as they slid
apart, and Megatron purred in approval as Soundwave’s flexible glossa wrapped
around his thumb. “This is lovely- so unique. I would –ah- love to feel this against my valve, if you would be willing. But-
for now, a kiss, sweet?” he whispered, and grinned when Soundwave immediately
pressed against his servo.

As soon as Megatron took his servo out of the way, Soundwave
leaned up to kiss him, awkward but very eager. It was more than rare for
Soundwave to be awkward, but it was cute,
and Megatron purred as he returned the kiss. As he’d thought, that slender
glossa twined easily with his, muffling a groan of pleasure- and Soundwave’s
field finally blossomed open fully into a shimmer of pleasure/anticipation/nervousness/trust. Even better than the kiss.

Soundwave eventually leaned back away from the kiss, mostly
so he could pant for more air, then moaned and rocked down a bit further. There
was a stretch, but nothing unpleasant, and Soundwave crooned a soft, shaky
noise up at Megatron as he felt the first of the ridges press against the rim
of his valve. Another rocking motion, this one much smaller, and the ridge
popped inside in a quick flare of pleasure.

Megatron’s engine was purring louder against him, field
rumbling arousal/bliss/pleasure, and
Soundwave wanted to feel more of that- wanted to get more pleasure, to give more, so he slowly lifted up and
rocked back down a couple of times in an effort to loosen his calipers up.

An effort that worked, pulling a startled, staticky cry of
pleasure from him as he sank down much further than intended. OH, Primus-

Megatron inhaled sharply, hips twitching up despite his best
efforts, and steadied Soundwave’s frame with both servos to keep him from
sliding down further. “Ah, Soundwave-
easy, are- nnh- are you all right? You feel… amazing, gorgeous, so hot, and your optics- you are beautifully expressive, do you know that? Such
bright optics, so sweet- I can see your pleasure unfold.”

Vents gusting hot air to help cool his frame and keep his
control, Megatron cupped a servo against Soundwave’s aft and squeezed lightly,
sliding the other servo up his partner’s side to brush over the glowing lines
in his stomach. And, ah- apparently
Soundwave was more than all right, because it only took a few deep vents for
the spymaster to start working himself down again, this time stopping tantalizingly close to taking his entire
spike.

“That’s it, Soundwave- so good, and, mm, impressively flexible- come on, just a bit further?
You can do this, gorgeous- one more little motion, sweet?”

Megatron sounded almost needy,
and it reached Soundwave even through the haze of pleasure. Oh- he’d been
rather slow about this, hadn’t he? And he didn’t want to keep Megatron waiting,
so he pulled himself up, paused for half a nanoklik, and rocked down again-
and, this time, felt his node grind against the area just above the base of Megatron’s
spike.

Helm lolling back, he moaned softly and loosened his bracing
grip on- whoops, he was digging his claws into Megatron’s upper arms. Offering up
a soft smile, he let his data-cables wrap down and around the warlord’s frame,
then lifted Megatron’s hips at the same time as he propped himself up slightly.
He wanted to feel Megatron, wanted to
feel those ridges slide in and out of him, but his knees had decided not to
cooperate and he wasn’t sure he trusted himself to move steadily. So- he could
leave it up to Megatron, ri-

Ooh-

 

Whispering “thank you, beautiful”, Megatron slide his servo
down from Soundwave’s aft to hook under his thigh, supporting him gently as he
thrust up into that beautiful valve. Not hard, just a slow, gentle motion, then
again, rocking in and out of Soundwave and gradually easing him open further. And
talking to him the entire way, having already figured out how much Soundwave
liked it. “So good… that’s it. Let me hear you, beautiful… let me hear your
pleasure?”

To his delight, Soundwave obliged. Every thrust from then on
drew a soft, staticky cry from the spymaster, gradually getting louder as
Megatron started to thrust harder. When the thrusts no longer met any resistance,
Megatron lifted Soundwave a bit higher, pulling out further than before and
then thrusting harder. The deeper, stronger thrust earned a louder cry, but,
just to be sure, he paused to ask- he needed to be certain it felt good. “Soundwave,
my sweet- such beautiful sounds, but- do you like that? Do you want more?”

Soundwave was caught a bit off guard by the deeper motion,
but Pit yes, he wanted more. Much
more. Warbling the steadiest affirmative he can manage, he pushed himself up
and sank back down to mimic the motion, then relaxed completely against
Megatron- leaving it up to the larger mech to decide what happened from then on.
Ohh dear Primus- that was it, he was done. This was amazing, and he absolutely wanted more, but his knees were still
uncooperative and the praise had him
wanting to do nothing more than just bury his face in Megatron’s throat and
moan.

Gripping onto the warlord’s arms in anticipation, Soundwave
gently squeezed the powerful frame with both data-cables, trying to encourage-
then gasped as Megatron did exactly what he wanted Megatron to do. Namely,
lifted him up and then brought him back down to meet the next thrust, rubbing
the ridges on that lovely spike along the inside of his valve rim.

“Ah- thank you for your trust, Soundwave, “ Megatron purred,
then gave up on coherent speech for now and just continued to thrust, reveling
in the sounds of bliss he was earning. Soundwave’s servos were gripping his
plating tight enough to dig the clawtips in, but he couldn’t bring himself to
care in the slightest, and the rhythmic squeezes of the powerful data-cables
around his frame only served to spur him on. Soundwave was beautiful, glowing frame and half-static voice alike, and to hear
his loyal friend in such pleasure was absolute bliss.  

And there were benefits to having such a light partner, one
of them being that he could easily shift the angle of Soundwave’s hips to try
for different, better spots. A careful motion, then another, then a slight
angle back, and-

Completely past shame, Soundwave squealed in pleasure as the calipers at the very back of his valve
clamped down around the tip of Megatron’s spike, rocking his hips down and into
the thrust to feel the friction against- what was that?

Frame tensing, Soundwave held himself in position, a hint of
curiosity flickering through everything else in his optics, then moaned quietly
as he realized what that must be. Well- as it was realized for him, by a soft spreading feeling deep in his belly. That must be the entrance to his
overflow tank opening, he hadn’t felt it before but it must be, it made sense, and-

And his next cry was a quiet, pleading whine, accompanied by
another rock of his hips, trying to get Megatron to-

He knew the function of an overflow tank, and, since there
was no risk of any unintended consequences, he wanted to experience at least
part of that function for himself. He wanted- Primus, he apparently wasn’t quite
past embarrassment, but he wasn’t even remotely
ashamed of wanting to feel Megatron fill
him.

 

“Easy- I have you, Soundwave, my beautiful, loyal friend,”
Megatron purred, sliding one servo up Soundwave’s back to offer more support
and pull him closer, and began to rock into Soundwave’s valve again. Small,
quick motions, not too hard or deep, meant to stimulate those deep nodes- and
to help hasten his own overload. He’d felt that shift against the tip of his
spike, he could guess what Soundwave was trying to ask for, and he knew how to
give it.

Growling in pleasure as he felt Soundwave’s claws skitter
against his plating, Megatron held his partner as close as he could while still
able to move, releasing enough of his control to let his charge build with no
restraint.

Keening against Megatron’s chassis, Soundwave dug his claws
in to brace himself against Megatron’s thrusts and let himself voice every
clear sound he could manage, trying to encourage the warlord to- yes, Primus,
to keep doing exactly this, please, more-

He could feel Megatron’s charge building, could feel it crackling
around both their frames, and Megatron was still calling him things like ‘beautiful’, and that was a very good spot being rubbed against with
an impressive amount of strength. Biting down on the plating he was nuzzling
into, Soundwave skreeled in pleasure as Megatron thrust once more- twice more-

And then his awareness spiraled down to nothing but the wet,
charge-filled heat flooding deep
inside him as Megatron overloaded. Overload hit Soundwave just a nanoklik
after, bouncing some of Megatron’s charge back to him, and the spymaster wailed
shakily against the plating his dentae were digging into. Every bit of his
frame curled around and against Megatron, valve calipers rippling around the
thick spike spreading him open, then he went limp into the larger mech’s lap
and moaned up at him.

Oh, Primus. He’d-
he’d never felt anything to do with his overflow tank before, toys didn’t work
for that unless they were specialized, but the novel stimulation of a large
partner must have done the trick. And now… now he had a spike filling his valve
so thoroughly that almost all of Megatron’s transfluid had ended up in his
overflow tank, and… mmh.

Wow.

…why hadn’t he asked about doing this before?

Okay… time for a reboot, everything was… sluggish.

Megatron purred softly and gathered Soundwave up, pressing a
kiss to his audial fin, but carefully didn’t pull out of the spymaster’s valve.
He’d leave that to Soundwave. “Such a pretty mech… oh, so, so pretty. And I
love your voice, Soundwave.
Different, but… still you, my lovely.
Oh… are you all right?”

Ah. Must have been a delayed reboot. Humming, Megatron
stroked circles on Soundwave’s back and sides, brushing away remaining
fragments of charge, and held him gently until he started to stir. “Ah, there
you are. I take it you’ve had fun?”

Yes.

Soundwave bumped his face into Megatron’s throat, trying to
communicate… something nice, he wasn’t sure yet, and squirmed around his stuffed valve and overflow chamber. That- okay,
that was a bit much, and he whined quietly and clawed his way up Megatron’s
frame until his partner got the message and gently pulled out.

That didn’t ease all of the pressure, though. His overflow tank
was definitely full and had closed to
stay that way, and Soundwave cupped a servo across his stomach to help himself
focus on the heat. Which allowed him to register the very slight swell in his own stomach, from… well, Megatron was larger than him, might not have had a spike overload in awhile, and… hm. The end result was Soundwave’s overflow tank stretching to accommodate everything. It felt strange, but it was a very nice sort of strange, and much less messy than the
alternative. Though this was still messy… partly thanks to his own valve, there
was a considerable amount of lubricant slicking his thighs. Which didn’t feel
excellent.The full overflow tank, though? That felt excellent. Made him blush even more, but… wow. 

As soon as his frame was steady enough, Megatron stood up
with Soundwave in his arms, easily supporting the spymaster’s lanky frame with
one servo on his back and the other arm slung under his aft. “Relax- let us get
you cleaned off, Soundwave. We have some time before everyone else gets back,
so… unless you have any suggestions, I am going to take you to the washracks,
get you cleaned up, and then… I would like to take you back to my quarters.
What happens next is entirely up to you, but I would like to keep you curled
against me like this for longer. You are warm, you purr nicely, and I have
never felt you this relaxed. I would
like it to continue. Are you open to that?”

Judging by the quiet, shaky,near-musical crooning in his
audials, Soundwave was very open to this whole situation.
