PROLOGUE

Siurin hadn’t intended to have sex with both omegas, but when offered, he couldn’t think of a reason to decline. They said they were friends and roommates who often partied together and sometimes shared sexual partners. They’d had alcohol but didn’t appear drunk. It would be an easy release.

After leaving the noisy club, he accompanied them to their sublet apartment seven blocks away. The living room showed signs of rushed preparation, with various pieces of clothing and tubes of makeup lying around. The plastic coffee table held two smudged wine glasses and a half-empty bottle of red.

The taller, slimmer omega—Siurin hadn’t asked his name—picked up the glasses and carried them to a kitchen counter in the corner of the small room. The other omega pushed Siurin onto the sofa and straddled him before taking off his shimmery top.

“Can you fuck us both at the same time?” he asked. “You have the gear for it, don’t you?”

“I have.” Siurin felt vaguely entertained by having his limbs described as “gear.” Humans were strange.

“Awesome.” The omega bit his lower lip and ground down against Siurin’s mating organ.

The first man returned to the sofa and undressed without ceremony. He wanted to watch first, so he sat back and spread his legs, stroking his cock.

Siurin didn’t change forms fully—he didn’t do that with casual partners—but he let a few tentacles grow from his middle. He used one to penetrate the first omega, who made loud appreciative noises while staring at Siurin with half-lidded eyes.

The other omega knelt on the sofa with his ass pushed out. Siurin had no trouble getting his dick inside the man. The omega must have had sex with Vaellians often to be so well stretched.

Siurin brought both to orgasm a few times before climaxing into one of them. He sighed as some of the pent-up tension bled from his muscles.

A strange thing happened then. Pressure like he had never felt before grew in his underbelly after he came. It wasn’t unpleasant, but it unsettled him enough to book an appointment for the very next day.

The examination confirmed his suspicion.

“The scan shows at least ten nearly full-formed eggs,” the doctor said. “I recommend finding an omega surrogate for oviposition in four months’ time at the latest. Unless you have a stable human partner or a different type of private arrangement, choose a suitable clinic. You can find several leaflets in the waiting room.”

Three weeks later,on a Thursday evening, Siurin sat at his computer filling in forms and scrolling through pictures of young omegas. It felt odd to pick and choose among them. He didn’t like dating apps, and this was arguably worse. The clinic used clever language regarding the omega surrogate auctions, brushing over the problematic parts, and maybe it worked on some, but Siurin couldn’t help the creeping sense of guilt. Howwas buying sex for pleasure condemnable, but bidding on a surrogate for oviposition wasn’t?

Abruptly, his moral objections were forgotten. He paused his scrolling and stared at a picture of a half-naked young man with narrow shoulders and vulnerable eyes. The omega sat hunched down, covering his nipples with folded arms, clearly uncomfortable having his picture taken without a shirt on. He seemed to be blushing. His lips were small but plump, his jawline soft, and his hands appeared frail with elegant fingers and slim wrists.

Siurin leaned closer and clicked on the omega’s profile. Gideon was twenty-four years old, a sales associate in retail, five feet six inches tall and 150 pounds, in excellent health, approaching his heat in May. It would be his first time as a surrogate. Another picture showed him smiling, visibly more relaxed when he was dressed.He must be shy, Siurin thought.Yet he’s so beautiful.

The auction was already ongoing, the number beside Gideon’s name rising every few seconds.

Siurin didn’t hesitate. He added a thousand to the sum and clickedsubmit. A few seconds later, the sum jumped up again. He bid higher.

Two hours later, the deal was done. He received a congratulatory email with several attachments containing extensive information about sex with humans, omega heats, and oviposition into a human womb. He would read those later—he knew most of it already. For now, he pulled up the picture of Gideon on his screen. Such a sweet and gentle face. None of the omegas who approached him at clubs and bars looked like that.

And Siurin would get to have heat sex with the man and place his eggs inside him. He became both aroused and nervous thinking about it. Neither of them had direct experience with oviposition.

Siurin saved the picture on his phone and closed it. He’d better study all those attachments.

Upon meeting your surrogate,remain in human form. You are allowed to attempt to initiate sexual intercourse with your surrogate even before his heat begins. If you construct your human form according to the provided guide (see sample images in Appendix E), your surrogate will be attracted to you and affected on a physical level, thus easily persuaded to engage in sexual intercourse shortly after meeting you. You will be able to determine his willingness by the pheromone-saturated discharge from his sex organs. When you detect the pheromones in the air, you can safely ask for penetrative intercourse. Use one of the suggested phrases in Appendix C. However, never make physical contact without explicitverbalconsent.

The initial sexual intercourse should be performed in your human form except for your ovipositor. Most surrogates accept the ovipositor in its natural shape—in some cases, the omega will be visually enticed by its size and shape. However, this cannot be assumed. Do not use your exposed ovipositor as a primary tool of seduction. While copulating, do not, under any circumstances, try to perforate the entrance to the omega’s womb at this stage. You can stimulate the closed entrance using the petals of your ovipositor. The protruding lump of tissue is infused with nerve endings that will send powerful signals directly to the pleasure center in the surrogate’s brain.

During copulation, the omega might make loud noises or express himself verbally by calling for a nonexistent deity, pleading, uttering vulgar slurs, or enthusiastically agreeing without being asked a question. The omega will not expect you to respond to these exclamations. These vocalizations, while nonsensical and sometimes disturbing, are completely natural and are merely evidence that you are stimulating the surrogate’s sex organs in a desired way.Do not stop or reduce the stimulationwhen this happens. The surrogate will experience one or multiple climaxes, which you will notice thanks to the excessive production of the natural lubricant from his anus and the release of fragrant semen from his penis. At this point, you can give way to your own pleasure. Inform the omega whether you wish to release the nurturing liquid into his anus or somewhere else. Make sure your surrogate agrees with the target. If you release inside the omega’s anus before retracting your ovipositor, make sure the surrogate’s buttocks are placed on a waterproof blanket or poised above the floor to avoid soiling furniture.

See Appendix B for a step-by-step guide tohygiene andcare after sexual intercoursewith a human omega.

After the intercourse, the surrogate will seem fatigued—he will have slower, sometimes slurred, speech, languorous movements, curved lips, and half-closed eyes. It means you were able to penetrate the surrogate in a way that he found pleasurable, and he will be likely to offer you his inner organs for oviposition at an opportune moment during his heat cycle.
