OVIPOSITION

From the Guide to Successful Gene Propagation, Titanoboa Clinic, January 2265. Loosely translated from Vaellian.

Even if the surrogate shows signs of changed awareness or loses consciousness entirely, continue the oviposition to your satisfaction. The loss of consciousness is not dangerous for the surrogate. Quite the opposite. The surrogates who are unable to loosen their inner organs enough to accept the offered number of eggs will relax sufficiently while insentient. At no point during the oviposition will the omega experience pain. Your enjoyment during the oviposition won’t be negatively affected by the omega’s diminished cognitive capacities. When a human omega’s womb is penetrated during heat, his brain is steered solely by his basic mating urge. He orgasms even in his sleep, and his frequently contracting inner muscles will provide you with the same pleasurable stimulation as if he were cognizant.

Gideon rested in the hot tub while Siurin was doing something inside the room on a large tablet. From what Gideon had been able to comprehend, the alien owned an IT company and had to attend meetings at odd hours with coworkers from different time zones. He’d assured Gideon that he’d always be available for him and that Gideon’s heat was a priority so Gideon wasn’t worrying about it.

The air was cool late in the evening. The hot tub bubbling cycle had stopped, and Gideon stretched his legs. He took a sip of the lemonade he’d been drinking. It felt like a vacation except with sex on tap while he was getting paid an obscene amount of money for his services. He grinned, feeling unreasonably smug. On top of that, his alien seemed to be quite the gentleman. Gideon was tentatively looking forward to the next step—eggs.

Rubbing his belly idly, he drank the lemonade. With how the suite was oriented and the terrace screened, he couldn’t see the other rooms, but he knew there were many. The clinic’s parking garage had been almost full when he’d arrived. How many clients were currently in the building? How many were fucking right then ? Wasn’t it fascinating that humans and Vaellians had found such a convenient way to fulfill each other’s needs?

A sound from below made him pause.

Was that…? Oh yes. It was definitely a moan. The rooms were soundproofed because, obviously, people and aliens came here to breed wildly together. But out here on the terrace, it was plausible that he could hear other clients, especially if they left their balcony doors open.

Another moan, louder.

Gideon was about to get up and go back inside. It felt creepy to listen.

“Oh my God. Please. Yes.”

Then came the clicking dolphin noises.

“Uh-huh. Aaaaah. Aaaaah! Yes! There! Right there. Aah. Aah. Aah. Aah…”

That was excessively noisy. And arousing. The omega gave out short, rhythmical shouts, needy and joyous at the same time. They rose in cadence as the alien’s sounds of pleasure got louder.

“Fuck yes! Yes! I feel it! It’s coming. Aah! Aah! Aah! Aaaaaaugh ooooh. Aaaauuuuuaaaaaaah!”

The final scream made Gideon climb out of the tub. He threw a bathrobe over his shoulders and hurried inside while the omega downstairs chanted “Oh my God!” in a guttural voice. Gideon closed the sliding door behind him, and the noise quieted.

Siurin looked up from the sofa. He must have heard. He often reacted to scents and sounds more than a human would.

“Did hearing the omega during copulation make you uncomfortable?” he asked in his usual matter-of-fact tone.

“A little. I felt like I was intruding.”

“I understand.”

“Was that… Um… Were they…?”

“Judging by what the Vaellian said, he penetrated the omega’s womb and released the nurturing liquid.”

“So the omega already has the eggs inside him.”

“Yes.”

“He sounded as if he liked it.”

“The Vaellian stimulated the channel to the omega’s womb, so I assume the omega experienced a prolonged breeding orgasm.”

“Was the Vaellian saying something? In your language?”

“Yes. It was rather explicit. You might find it disturbing.”

Gideon smirked. “Try me.”

“He said he would fill the omega’s insides through his anal opening until the…um…nurturing liquid would pour out of his mouth. Then he talked about stretching out the omega’s birthing channel with his limbs until the omega fainted and penetrating his various orifices for the entire time the omega remained unconscious.”

“That is a little disturbing.”

“I agree. But I assume the Vaellian wouldn’t do those things. It merely aroused him to say them.”

“He didn’t say nurturing liquid , did he?” Gideon guessed.

“Like humans, even we have words in our language that are considered inappropriate in polite company.”

“Like cum? Or fuck?”

“Something along those lines, yes.”

“And some Vaellians like dirty talk. Good to know. Do you like it?”

“Saying inappropriate things during intercourse? I don’t mind, but it doesn’t excite me. I prefer to compliment my partner. It seems more fitting.”

“Can you do that in English?”

“When we copulate? Yes. You’d like to hear it?”

“Uh-huh. I think so.”

“Then I will speak in English when I penetrate you.”

Gideon bit back a grin and tightened the robe around his waist. “During my next wave, can we make sure the windows are closed?”

Siurin nodded. “You don’t want others to hear you when you’re experiencing pleasure. I understand.”

“Thank you.”

“I will make sure the doors and windows are closed before we copulate.”

Gideon’s lips twitched. “Awesome.”

“If you are not experiencing any symptoms, I’d like for you to rest. The next heat wave will be exhausting for you, especially if we proceed with oviposition.”

“I’ll go lie down.”

Siurin nodded again, a little slower than a human would.

Gideon went to pee and brush his teeth. In the bedroom, he hung the bathrobe on a hook by the bathroom door and climbed naked under the covers. He didn’t like wearing pajamas during heat, and Siurin had already seen him naked, so he saw no reason for modesty.

The sounds the omega downstairs had made kept replaying in his head. It was likely that Siurin would be able to plant his eggs into Gideon’s womb during the next wave. Gideon tried to imagine how it would feel but couldn’t. After Siurin massaged the closed gate to Gideon’s womb during the first heat wave, Gideon wasn’t sure he would survive a stronger orgasm. And the eggs were supposed to plop in and stay there. Pleasure center overload .

No way would he be able to sleep. He was too hyped up and aroused. Feeling vaguely guilty, he began playing with his nipples. The arousal coursed through his body, and his hole felt slick. He rolled his nipples between his thumbs and forefingers and thought of Siurin’s tentacles suckling on them. That would be nice… Could he ask for that?

Eventually, he must have fallen asleep because the heat wave woke him up.

He was wet and aching. He opened his eyes only to see Siurin walking in with a tray.

“Drink this.”

It was juice. Gideon drank eagerly, emptying the entire glass. Siurin placed a couple of water bottles on the nightstand. Then he tugged the comforter off Gideon’s body.

“How are you feeling?”

Already mindless with lust, Gideon spread his legs.

“It’s getting stronger. I need you.”

The tentacles burst out of Siurin’s body, the change much faster than before. His arms and legs blackened and transformed until only his upper torso and head remained human.

The smooth black limbs coiled and snarled all around Gideon, spiraling up his legs and wrapping around his arms. Siurin glided over him, encompassing his much smaller body. When Gideon felt pressure on his leaking hole, he sighed with relief and sank into the alien’s hold.

“I’ll fill you and pierce your womb. I’ll stretch the mouth deep inside you and push my eggs in there one by one. Are you ready?”

No, he wasn’t, but he wanted it all the same. “Yes. Yes. Do it.”

Siurin’s dick felt bigger than last time as it snaked inside Gideon, filling him up in the most delicious, satisfying way. It seemed to be expanding in waves. When it prodded the mouth to Gideon’s womb, a shock of pleasure flared from the spot.

“Oh yes!” God, Gideon would yell like the screamer downstairs. But who cared? He was having the time of his life.

“You are small and pretty, so very pale in my arms. You look fragile. I like that.”

Intense pressure made him gasp. Like a spear poking the entrance to his womb. It didn’t hurt, but he felt it everywhere.

“You’re ready, dear Gideon. The gate is closed but swollen and soft. I’ll fuck it open.”

The sensation incapacitated him. Even if he weren’t wrapped in what felt like a dozen tentacles, he couldn’t have moved. Siurin lifted him, elevating his hips while lowering his shoulders. Gideon hung there, his body comfortably supported, while Siurin’s independently moving dick burrowed deeper, retreated, and pressed again.

“A virgin womb. Opening up. For me. Oh, so soft.”

All of a sudden, Gideon came, screaming for his life.

“Yes, Gideon, you’ll come many times. So beautiful. Scream, little human. Louder. Scream.”

Siurin’s dick seemed to twist and turn, like a damned corkscrew, and Gideon wailed with another orgasm.

The climax grew in intensity, throbbing and tingling, coursing up and down his spine, and he gasped to catch his breath.

His entire womb pulsated while his hole clenched erratically.

“Oh my God!” he yelled. “Oh! Oh! Oh God!”

It pushed everywhere at the same time, expanding his hole, pulling on his rim, stretching the little mouth deep inside him, until he felt a distinct touch inside his womb . The soft caressing of the oversensitive tissue sent his entire body into an orgasmic frenzy.

Every nerve cell in his body buzzed and crackled while the climax raged through him for an endless moment.

Siurin stilled, holding Gideon tight. Gideon shivered, impaled through and through. The alien was all around him and inside him, and he felt wonderfully helpless.

“Shh, my beautiful. All is well. I’m inside you now.”

Panting, Gideon tried to wrap his head around the glorious sensations in his middle.

“What’s happening?” he gasped, overwhelmed.

“I’ve pushed through your breeding channel, and the petals of my ovipositor have unfolded inside your womb.”

He didn’t dare to move a muscle. He probably couldn’t.

“Every small thrust will make you orgasm immediately.”

Peeling his eyes open, he looked up at Siurin looming above him, only head and shoulders peeking out of the tangle of huge, python-sized tentacles. His skin had a blue-gray hue, his ears were pointed, and his hair was gone. His eyes were entirely black, with no irises.

He looked fascinating.

And he was currently lodged in Gideon’s core, joined with him in the most intimate way.

“If you weren’t in heat,” Siurin whispered, “this would have been excruciatingly painful for you.”

Something flashed in his midnight eyes. Maybe the idea stirred something in Siurin that Gideon shouldn’t think about. Not now, when the alien had complete power over him.

Then the cock inside him tugged, and Gideon forgot about the vague sense of danger. He burst with pleasure, crying out.

“There. You look exquisite when you orgasm. I need to move now. You’ll be climaxing a lot, and it will feel like you can’t take it anymore, but that will pass. Then you’ll enter a different state of mind. You’ll be as happy as a human can be.”

The tentacles holding him tightened subtly. A beat of silence followed when everything was still.

Suspended in time and space, impaled all the way to his core, Gideon slowly exhaled. It felt like the eye of a storm, a moment of tranquility before all hell would break loose. He stared up into Siurin’s strange face, his infinite eyes…and he gave himself over.

There was no going back from here.

The thick, long cock inside him moved again, fire and ice collided in his core, and he shrieked with what could only be described as an exuberant, life-affirming terror.

This climax wouldn’t peak and go away. The pleasure rose. And rose. And got even stronger. He gritted his teeth, but it grew even more powerful, and his jaw slackened. His eyes rolled into the back of his head. He could die any moment now. His insides would detonate, and his nerves would go up in flames.

But Siurin’s dick pumped inside him in an unwavering rhythm. It massaged his hole, pressed on his gland, and the petals caressed the most sensitive tissue inside his womb while pulling the stretched mouth open even wider.

The orgasm burned, raged, and exploded over and over. Curiously, he was still alive.

His throat was raw from screaming.

Then suddenly, Siurin’s cock grew even bigger.

“You’re very beautiful, Gideon. So very beautiful. So small.”

Gideon’s eyes flew open, and he stared at the alien poised above him, the total mass of his body ten times the size of Gideon.

“Small. Sweet little human. Helpless. Just for me.”

The clicking noises scattered between Siurin’s words grew louder.

“You’ll be breathtaking when round with my eggs inside you.”

The base of Siurin’s dick widened, stretching Gideon’s rim.

It felt like a knot, but it traveled deeper into him.

“Oh God! God!” A part of him must have been terrified, but he couldn’t process fear. He was submerged in all-encompassing bliss, every muscle in his body shivering with delight.

Suddenly, the mouth of his womb stretched and accepted what felt like a humongous girth of Siurin’s growing cock.

Gideon lost sensation in his extremities, and all of him focused on the place where a round object entered his orgasming womb.

Like lightning, it struck the pleasure center of his brain.

He gasped, silent for once, his eyes bulging out of his head.

“Oh yes. Such great joy.” Siurin’s words sounded broken, the accent all wrong. “Mmmmmm. Oh, I like this very much. Your womb is so soft. I’ll fill it well. Such a beautiful vessel for my eggs.”

Before Gideon could process what had just happened, Siurin’s cock thickened anew.

Another egg was passing through.

He wasn’t ready. He was still full of sensations from the first one. It was too much. Way too much. His poor womb. He couldn’t…couldn’t…

“Aaaaaaah! Aaaaah! Aaaaaaah!”

His screams must have shaken the entire building as another egg plopped inside him, jostling the first.

The orgasm would tear him into pieces any moment now.

And Siurin’s dick was already delivering the third one. The alien was humming and making his dolphin sounds, his free tentacles undulating in the air. His black eyes were pinned on Gideon.

“I’ll give you many more.”

At that moment, Gideon didn’t know if it was a threat or a promise.

When the third egg stretched the mouth to his womb and plopped inside, he began spasming. His legs and arms jerked in the alien’s hold, and he opened and closed his mouth like a fish out of water.

Was he in pain?

“Shh, my little vessel.”

A tentacle entered his mouth and throat, another spiraled around his throbbing cock, and two latched on to his nipples.

They all pumped, suckled, stroked, and milked, and the pressure in his core grew and grew…

And then… Peace.

His body stopped struggling. It opened fully, all tension dissipating, and the sweetest tingles of joy spread through his nervous system. Every muscle relaxed, mind at ease, and he clearly felt his hole stretch as the fourth egg traveled to its destination.

He didn’t try to prepare himself in any way. He just let it happen. His climax surged as his womb expanded to accept the intrusion, and he heard himself groan.

It was ecstasy. Pure, raw euphoria.

At some point, he stopped counting them. He felt gloriously full already, but the eggs kept coming.

He was proud of himself for remaining conscious even as his brain seemed to sparkle and his vision blurred.

Then Siurin abruptly ripped his cock out, and Gideon’s womb responded by tightening around the eggs. He shuddered with one last powerful wave of pleasure, then slumped, exhausted.

Siurin filled his slack hole with a curling tentacle to simulate a knot, but Gideon wasn’t sure he needed it anymore. The heat wave was over, and he was as full and sated as he could ever imagine being. He placed his hand on his swollen stomach and fell asleep within seconds.

When he woke up, it was daylight. He had no idea how long he’d been out of it. Siurin sat beside him in his human form butt naked, balancing his laptop on his thighs.

“Hi,” Gideon rasped.

Siurin put the laptop on the floor by the bed and held a bottle with a straw to Gideon’s lips.

“Hello, dear Gideon. You need to drink this.”

Gideon gratefully accepted, slurping up half of the bottle in one go. It was some sweet, juicy drink that tasted vaguely of melons. He liked it.

“You slept for a long time. Do you need to go to the bathroom, perhaps?” Siurin asked.

“Probably a good idea.”

Planning to get out of bed, Gideon pushed himself up on his arms, only to crumble a heartbeat later. A flare of sensations made him curl onto his side and gasp for breath as his hole released a trickle of slick and his hard cock jerked. Was he…coming? It felt almost like an orgasm. What the actual fuck?

The feeling slowly passed, and he grabbed his distorted stomach with both hands, stroking it curiously.

The eggs in his womb. When he moved, they bounced and rolled and… This was sick! He could feel the individual bumps through his stretched skin.

“Your womb is still getting used to them. It should get less sensitive with time. After fertilization, you’ll be able to walk and move without getting overwhelmed.”

The fertilization. Because this was just the beginning.

Oh God.

Thick, warm tentacles swirled around him and gently lifted him from the mattress. Siurin barely jostled him as he wrapped him in his many limbs and carried him to the bathroom. Very slowly, the alien turned him and deposited him right onto the toilet. Gideon shivered with awareness, but it passed quickly. The eggs felt nice. Scary, but very very nice.

He couldn’t stop looking at his big stomach.

“How many are there?”

“Are you asking how many eggs I’ve put inside you?”

“Yes.”

“Twelve,” Siurin stated proudly. “I’m very attracted to you, Gideon. I found the oviposition exceedingly satisfying. Looking at you now, at your big stomach, makes me aroused anew.”

He retracted his tentacles and waited in his bare human body, his large dick half-hard, while Gideon sat naked on the toilet in front of him.

“Thank you for the compliment. But…um. Can I pee in private?” Gideon asked, biting back an awkward laugh. It was bad enough that he had to do it sitting down, which he otherwise never did. He didn’t need an audience for it.

“I apologize. I know humans prefer privacy when performing certain bodily functions. Call me when you have finished urinating, and don’t stand up on your own, please. I wouldn’t want you to hurt yourself if you fall.”

With that, Siurin walked out of the bathroom and closed the door.

Shaking his head, Gideon chuckled, then grabbed his belly with a gasp when his womb tightened.

“Laughing is not allowed either,” he muttered to himself. “Good to know.”

It took a while, but he managed to empty his bladder. He wanted to flush, but the attempt to turn and reach for the handle sent another flurry of tingles through his middle.

“Oh for fuck’s sake.” He gritted his teeth as he flushed the toilet. He shivered through the strange sensations, breathing deeply as water gurgled under his butt.

“Siurin,” he called. “Can you help me?”

Siurin immediately opened the door. He must have been waiting right in front of the bathroom.

“Is taking a shower too complicated right now?” Gideon asked.

The alien bowed like a high society butler, and his tentacles shot out toward Gideon. “Of course not,” he said pleasantly as he lifted Gideon and smoothly moved him into the large open shower stall. “Warm water will relax you.”

It felt like levitating. Using his nimble limbs, Siurin washed Gideon while holding him suspended in a sitting position. He didn’t make a single movement too hasty to disturb Gideon’s tender womb.

Clean and dry, with his teeth brushed, Gideon rested on the bed while Siurin stroked his stomach.

“Do you have any questions about the fertilization?”

Gideon was trying not to think about it too much. Not because he was afraid, but because he was worried of becoming afraid when he wanted to enjoy it.

“Do you know the guy?” he asked.

“Your fertilizing partner’s name is Tituan. I didn’t know him before the joint appointment we had at the clinic, but I found him perfectly agreeable. He’s a respected member of the Vaellian community, and his family is keen for him to produce progeny. He’s fifty-three years old and reasonably wealthy. He’ll be able to provide his young with a good education once they come out of water.”

It was so bizarre. Gideon knew that the Vaellians spent the first few years of their lives underwater. Now he carried eggs that would become living beings, swimming in someone’s pool until they reached bodily maturity and learned to change forms. He felt a little proud of himself. He patted his belly, imagining the future little Vaellian babies floating around like octopi.

“I can smell your heat wave coming. It will begin within the hour. I should feed you, then I will call Tituan. He is already in the building.”

For a moment, Gideon thought Siurin would get up and cook for him. But then a dark tentacle appeared in front of his face and tapped his lips.

Oh yeah. That was much easier.

He eagerly opened his mouth and sucked. Siurin transformed, wrapping his limbs around him, and began subtly rocking him. With the slow, gentle movement, sweet currents of pleasure swirled around Gideon’s full womb.

He gulped the release, savoring the taste, and accepted another tentacle. Siurin made soft little clucking noises as he gave Gideon his feeding limbs one after another. Feeling slutty but not enough to be ashamed, Gideon sucked them off like cocks, putting on a bit of a show for the alien and eagerly opening up for deeper throat-fucking. He even moaned. Siurin did say that the act brought him pleasure, didn’t he? Judging by the sounds he was making, he was indeed enjoying himself a lot.

“Do you find the feeding arousing too?” Siurin asked when he slowly slid the fourth bulbous tip across Gideon’s wet lips.

“Yep.”

Gideon traced the tentacle with the tip of his tongue. Siurin’s eyes darkened, the whites of his eyeballs flooding with black ink. He rubbed the flat of Gideon’s tongue with the appendage, and Gideon opened his mouth wide, his eyelids drooping. He let out another moan. God, he was such a slut. The shame only made him want it more.

Siurin thrust teasingly and withdrew, observing Gideon’s reaction.

Licking his lips, Gideon gazed right back at him. He found the alien even more handsome like this. Siurin’s natural form made him seem powerful, almost godlike.

“You can thrust deeper. Make me gag.”

“I wouldn’t want to make you vomit.”

Gideon grinned. “You won’t. Fuck my throat like a hole. Do it.”

Suddenly, Siurin seemed to grow before him. The feeding tentacle pushed into his mouth and throat while loops of warm muscle tightened around his arms and torso. Then Siurin began to thrust, smoothly fucking Gideon’s throat. Gideon struggled to breathe through his nostrils, but his heat-muddled mind loved it. One tentacle spiraled around his throat, and he reminded himself of the eggs in his womb. All the ways he was being used and filled… And soon, another alien would penetrate him and use him and fill him…

When the feeding limb reached Gideon’s esophagus, Siurin came. Or did it feel like an orgasm for him? Gideon swallowed compulsively around the invasion in his throat while the liquid poured into him. Siurin slowly withdrew, and Gideon pulled in much-needed air.

“That was highly satisfying for me, Gideon. Thank you. I hope you enjoyed it too.”

“I did.”

“Good. Feeding a sexual partner is erotic for us, but I didn’t know humans perceived it like that as well.”

“Not all humans, I imagine. But I like it. It’s hot when you fuck my throat.”

Siurin’s mouth curved in a strange but seemingly genuine smile. “I’ll keep that in mind.”

The creamy liquid filled Gideon’s stomach without making him feel stuffed. He felt energized and horny, an ideal state for what was to come.
