Summary
     Arthur and his pregnant boy-wife Merlin video chat.
It was past midnight citadel time when Arthur withdrew to his sleeping cubicle.
Time had little meaning when all that could be seen outside the few windows was
the unbroken darkness of space, but he'd been on duty for almost twenty four
hours and he was tired and desperate for sleep.
But if truth be told, he was almost as desperate for something else. He palmed
himself, soothing the lusty throb in his swelling knot. As soon as the doors
clicked shut behind him, he threw off his shirt and turned on the screen
opposite his bed. Merlin was already waiting for him.
Arthur's little omega boywife was settled in their large bed back at the
citadel. He was naked, a hand resting on his heavily pregnant belly. In the
faint, golden light of their bedroom, his skin was like the finest silk.
Arthur's cock hardened at the memory of touching all of that smooth,
unblemished loveliness.
He thought of spooning the boy and fucking him - gently, lovingly - until
Merlin spilled beautiful, surprised sounds, as if he couldn't quite believe how
good Arthur felt inside the tight sheath of his anal channel.
"My lord," Merlin said. His pale, sensitive face came alive with a adoring
smile that was just for his alpha. His violet eyes sparkled.
Arthur fell back in his bed, propping himself up against a pillow. "I've missed
you," he told Merlin. "I've thought about you all day."
Merlin got up on all fours, a difficult process in his present state, and crept
closer. He settled on his knees with his big bump and swollen, red-tipped tits
protruding in front of him. It couldn't be long now. Arthur was due back in
three weeks, and he wasn't sure he'd be in time.
"You look tired," Merlin said, resting his long, fine hands on his taut
stomach. There were pink stretchmarks under the little bud of his navel, and
Arthur longed to trace them with his tongue.
Arthur rubbed his eyes, smiled at his beautifully fecund omega. "Long shift.
But seeing you makes it all better. How are you?"
The boy sighed. "I just want it to be over. My back aches, I have to pee all
the time and my feet are swollen. Your sister and her omega try to look after
me, but I guess they're pretty tired of me by now." He was stroking his domed
belly as he spoke, it looked wonderfully strange on his very young body. "I'm
huge and fat. You'd never want me if you were here, even if it's your babies
I'm carrying."
Arthur smiled indulgently. "Tease. You know I love that belly of yours. I'd do
anything to be there and look after you."
Merlin gasped, instantly aroused. Arthur loved his childlike helplessness, his
trembling horniness, how his body was so attuned to his alpha's moods. "How
would you take care of me?"
"I'd kiss you. I'd kiss you everywhere," Arthur promised in a husky, honeyed
tone, loving how it drove Merlin wild. "I'd suck your swollen little toes and
lick that fat bump of yours all over. I'd plug up your boy-cunt and help you
stretch your new girly hole even bigger. I'd stretch it with my cock."
Merlin made an indecent, mewling sound at that, as if he was in heat again. The
last stages of his pregnancy had reduced him to a state that wasn't far from
heat. From what he told Arthur, he was constantly wet and ready, his knickers
always damp and musky no matter how often he changed them. It was embarrassing
to him, and a source of pride to Arthur.
"Show me," Arthur said, letting his voice sink to a growl that made Merlin
tremble.
The little omega crept back to lean against the pillows. The camera tracked
him, zooming in. As Merlin submissively parted his slim thighs, Arthur saw his
fierce little stiffness, all three inches of it. Below his taut, boyishly bare
balls, his new cunt was sopping wet, the pink lips glossed and shining with
girly juices.
Fingers already trembling, Merlin parted the fleshy petals, exposing the
remains of a hymen and the ribbed walls of his now fully developed birth canal
to the inquisitive camera. He teased a finger inside, and it came out
temptingly wet and glistening.
Arthur groaned, brutally aware of his own need. He wanted inside it that tiny,
snug space so badly, wanted to force it open and mark it with his seed. When
he'd been sent away, Merlin had been barely two months into his pregnancy, and
the only signs of his girl cunt had been a slight dimple on his taint.
Arthur had followed its development on the screen. He'd watched in wonder as
Merlin stretched and grew the burgeoning vagina through which he would, in
time, give birth to Arthur's babies.
Merlin had used glass rods at first, carefully lubed and inserted as per Gaius'
instructions. When the little hole began to self-lubricate, Merlin had begun
using slowly swelling plugs, which were to be left inside for hours while the
boy - desperately turned on, sweating and moaning and sometimes crying - tried
to go about his daily business.
The dildos came next. By then, his omega trait was more than a hole. The tight
little petals had begun to open up and grow, evolving into a proper vulva,
albeit smaller than a woman's.
Arthur wanted to fuck it with his tongue, open that delicate, tiny space and
taste its secrets, wanted to claim that second virginity just as he had the
first.
"Gaius says it won't grow back if I get pregnant again soon," the little omega
whispered timidly. "If I keep stretching it, and have multiple pregnancies, I
can keep it permanently open."
Truly hermaphrodite omegas were very rare. They were high maintenance due to
all the work needed to keeping them from reverting back to their male sex. They
were expensive, too, since they had to be kept pregnant and couldn't work, and
because of the fines that had to be paid by anyone wanting more than two
children.
To possess such a mate was a mark of status, but that wasn't what made Arthur
hard enough that he thought he might faint. The idea of his little boywife
permanently having full, heavy tits and a girly cunt as well as his boy-clit
and boy-cunt was almost too much.
But there was also the additional thrill of letting Merlin be unrestrained by
suppressants; unfettered by civility and allowed his natural heats, the
beautiful periods when the quivering sheath of his body milked Arthur's balls
dry of seed several times per day, until neither of them had the strength to
get out of bed.
Arthur opened his trousers and let out his swollen dick, stripping it as he
thought of the tight grasp of Merlin's ass.
"Is that what you want?" Arthur asked. "To be a girl as well as a boy?"
Merlin smiled shyly. "I've dreamt of it since I was a boy, before I knew what
it meant to be an omega. I loved playing house and dressing up in nice dresses
and all that..." When he said it, his eyes shone and his gaze grew soft and
dreamy.
Arthur could imagine him as a little boy, already playing at caring for a
husband. He sent a grateful thought to his father, who had gone out of his way
to find such a perfect mate for him. Merlin had been expensive, but Uther had
picked him anyway, and his instincts had been born out by the genetic tests,
and by Arthur's own pleasure.
"It's not just nice dresses, sweetheart," Arthur said. "You're still so
young..."
Merlin's eyelashes fluttered, and he cast his eyes down, as if he thought that
Arthur had accused him of being frivolous. "Gaius says I'm doing fine. I eat
and exercize and take my vitamins. But if you don't want it..." he pouted and
fondled his tits, pressing them together, creating a valley of creamy skin that
seemed to be made for Arthur's demanding manhood.
Even after so short a time together, Merlin knew how to manipulate his husband,
using his exquisite body and his naturally submissively erotic demeanour to get
what he wanted. Arthur swallowed and tried to compose himself. It was too easy
to give in.
His cock was telling him exactly how much it wanted to keep Merlin constantly
fat with babies, make him a trophy wife who did nothing except looking pretty
and pregnant, a living proof of his alpha's virility. The reality was that
Arthur had no idea how healthy that would be. They needed to discuss it, but
not now. He was far too horny for it, and Merlin deserved better.
"I want to make you happy," Arthur said, his voice low and dark. "That's all I
want. But we're going to talk about this when I return, and not now, not like
this."
He fisted his cock, and Merlin smiled and licked his lips as if things were
settled.
"I would suck that for you," he told Arthur, gazing up from under a thick
fringe of black lashes. "I'd be a good little wifey and wait for you when you
come home. I'd let you fuck my mouth as soon as you entered the door."
Arthur groaned. "What would you be wearing?"
"A babydoll and a tiny thong. Would you like that? I'd make myself pretty for
you. I'd be all made up, just the way you like it."
Arthur gulped, suddenly in danger of choking on his own spit at the thought of
Merlin's baby-soft pout painted a sinful red. "Yesss."
"You'd get to hold my hair and just take me. Plunder my mouth. You'd pull out
at the last moment and come all over my face, over my tits. You'd make me
filthy with it."
Arthur was fucking his fist now, aggressively tugging at his balls and knot
with the other hand. He stopped himself at the last moment.
"Enough," he growled at his teasing little boywife. "Show me. I want to see you
stuff every hole you have as I come."
Merlin's eyes flashed gold, and suddenly the pink case that held his toys was
next to him. He took out a thick plug first. He rubbed it against the lips of
his vagina, coated it with a luxurious layer of shiny juices. Then he leaned
back, managed to push a pillow under his hips, and parted his long, slim legs
even wider.
Arthur could see his asshole now; that dark little furl of a boy-cunt. Already
as wet with juices as Merlin's cunt proper, the centre was pink and puckered
into a generous rosebud, it's swollen state signalling his readiness to be
mated. Arthur wanted nothing more than to gift his omega's needy hole a heavy
load of his milky come.
"Stuff yourself," Arthur coaxed. "Want to see you cram that hole full for me."
Merlin gasped. His face was too red to be pretty, but all Arthur could think of
was how his boywife was so horny for him, too horny to care about being
seductive or beautiful. Too horny to want, or need, anything but him.
Like a true omega - subservient and naturally inclined to obey - Merlin only
nodded. He stuck two fingers into the elastic ring of his anus, scissored them
inside, widening his rectum, letting the nosy, tracking camera provide Arthur
with an obscene close-up of slippery pink flesh and the glossy walls of his
insides. Using his other hand, he guided the thick plug. He pulled out his
fingers, leaving silvery snail-trails of his essence on his rounded little ass.
At its thickest, the crystal-clear plug was a good four inches, but Merlin's
hole was hungry, and with a moan escaping the brave little omega's mouth, the
buttplug entered and was lodged inside the hot furnace of his body, leaving
only the stopper outside. Merlin gasped, and his tits heaved dramatically as he
panted.
"Oh, that's big," he said thickly, fanning his flushed face. "Almost too much."
"Not nearly enough," Arthur growled, knowing he was being bad, but helpless to
resist. "Your girl cunt, too."
The dildo Merlin chose was shaped like an alpha cock, with a swelling knot that
was controlled using a remote. It was a trashy pink, looking like something a
whore would keep, not a prince's consort.
"Suck it first," Arthur urged, pumping his leaking erection steadily.
Merlin's beautiful eyes teared up as he took the fat silicone cock all the way
to the knot. It wasn't a long thing, but thick, and the thought of soon seeing
it planted in his boywife's newly formed little pussy was making Arthur
desperate.
It was wet with saliva when Merlin pulled it out of his mouth. He teased it
along his tits, moaning in dreamy pleasure. He teased it over the pale dome of
his belly, then reached around to attempt to press it inside his cunt. The
slide was slow, and had them both holding their breaths. And then it was
inside, all of it but the knot.
Merlin sighed.
"I don't know if I can take the knot," he whined, fluttering his long
eyelashes.
"Cock tease," Arthur murmured darkly. "Just relax, and it'll fit, I promise."
Merlin mewled all helplessly, a sound of both pain and pleasure, but he had a
deep-seated need to obey, so he closed his eyes and pushed. The elastic flesh
gave, allowing the knot inside. Arthur watched it swell as Merlin pushed a
button on the remote. Then, when it was clear that nothing more would fit in
either hole, Merlin found an oversized pacifier, which he took in his mouth. He
sucked ecstatically as he grabbed a vibrator in his free hand and held it to
his tiny omega cocklet.
Merlin thrashed as he came, sobbing around his pacifier as he was consumed by
wave after wave of ecstasy. Arthur watched him, not allowing himself to come
until Merlin was lax and spent and sucking gently, interspersed with contented
mewls. His holes were still pulsing slowly around the toys. Arthur held his
knot, closing a hand around it, fooling his body into releasing thick, white
ropes of come over his chiselled abs.
He closed his eyes for a few moments, too overcome with his orgasm to do much.
When he opened his eyes again, he saw Merlin remove the now dripping toys from
his nether holes, and clean them and himself with magic. The omega kept the
pacifier in his mouth as he put on a pristine, white nightgown and white little
panties lined with an absorbent pad and curled up under the covers.
"Good night, love," Arthur whispered, and Merlin hummed a reply.
Arthur watched him fall asleep before he turned off the screen. He couldn't
wait to be back.
