It amazed him he’d have heat waves when he was like this. How could his body still want penetration after being stuffed to the brim?

But when Siurin gently stroked his stomach and teased his crease with another limb, Gideon felt small sparks of arousal in his groin. Yep. A complete and total slut. He would have laughed at himself if his mouth weren’t full.

“Oh, yes. You’re so very sweet.” Siurin released inside his mouth and offered him another tentacle.

After sucking off all four of Siurin’s feeding tentacles, Gideon felt sufficiently awake to remember his other needs.

“Can I visit the bathroom?” he asked.

“Of course.”

This time, the alien insisted on accompanying him. It was probably for the best since Gideon wasn’t sure he would be able to pee without falling off the toilet.

His belly was the size of a freaking medicine ball and just as heavy. But it also felt nice. The fullness was overwhelmingly satisfying, and Gideon couldn’t stop smiling. He peed, then Siurin held him in the shower.

To his surprise, he was able to walk back to bed, Siurin supporting him for balance. Gideon held his stomach with both hands, marveling at the roundness. His belly button protruded a little. With every step, the eggs moved, and his stretched womb tightened around them.

Which made him horny.

He really had turned into an animal.

Of course, Siurin sensed it. He climbed onto the bed and lay behind Gideon, engulfing him in his tentacles.

“You seem to desire touch. I can smell the rise of pheromones from your skin. I need to wait for your heat wave before penetrating you, but can I stimulate you in other ways?”

“Please,” Gideon whispered, his eyes closing. After everything he’d already been through, he trusted Siurin implicitly.

Siurin was indeed attracted to his stomach. He kept stroking and petting it with his many limbs. One tentacle spiraled around Gideon’s right leg, gently lifting it to open Gideon’s crease. Another slid over his cock, sucking it to hardness, while two suckers latched on to his nipples. Siurin’s independently moving cock rubbed through Gideon’s crease and massaged his closed hole.

“If you continue like this, the heat wave might come sooner,” Gideon murmured.

“Don’t you want that to happen?”

“I guess. What will you do to me? I read about it but forgot the details.”

“I’ll fuck you until you reach climax, and I’ll penetrate the channel to your womb. The eggs need sustenance, and I will release the nurturing liquid into your womb during your orgasm.”

“That was what the couple below us were doing when we heard them.”

“Yes.”

“And will we do it every heat wave?”

“Yes. I could do it more often, but penetrating you between waves could be painful for you.”

“You mentioned that earlier. How do you even know that?”

“Vaellians have been using humans as surrogates for a long time. But it was initially problematic.”

Huh. Gideon had never heard about that. “How?”

“During the twenty-first century, Vaellians visited Earth repeatedly in search of suitable vessels for their eggs. The flexibility of human bodies was promising, and our forefathers found human omegas very appealing. They took in several and conducted research.”

Gideon tensed. “You mean you kidnapped human omegas and experimented on them?”

“I wasn’t involved,” Siurin said defensively. He paused all teasing of Gideon’s body and held still as he explained. “It was two hundred years ago. I wasn’t yet alive. I believe twelve omegas were originally taken onto a Vaellian ship. After some hesitation, they responded positively to penetration, and their anatomy was deemed most promising for egg gestation. However, the first attempts at oviposition and fertilization had to be performed while the omegas were restrained and heavily sedated.

“Only after the researchers learned more about the human reproductive cycle and sexual behavior, did they find ways to perform the acts so that the omegas appreciated the experience. During heat, their wombs created a superbly hospitable environment for egg gestation. The Vaellian researchers even discovered a way to induce heat with synthetic hormones and thus accelerated the omegas’ heat cycles up to one heat a month.
