“So, these new species are from another world?” Questioned Meril, who stood next to the two researchers who had been working on the new Morphing Pills. The originals didn’t have too many issues, apart from the occasional side effects, which were already being worked on. However, as the news of people from another world coming here, the company that worked on them saw it better to start working on a better formula.

“An alternate universe, to be precise. Really complicates things, to be honest, but it helps that some of them agreed to a couple of tests and-” The tall, lanky cheetah was interrupted by his coworker, a shorter and wider lizard-folk, who pushed his elbow into his side.

“The important thing is, we have gotten far enough in the making and testing that we can move on to the most important part: testing it on live participants. Which is where you come in, as one of the prey. We have gotten two-”

“Wait, prey? I thought I would be…”

“We need to test them on people from other universes. We can’t exactly see if they work properly if the one taking them is from our world.” Interrupted the cheetah. “I think that was clear, given the nature of the test.”

“Ah, right. I just… Nevermind. So, who are the two others?” Meril asked, crossing his arms in front of his chest, only to immediately uncross them as the shorter researcher handed him a binder. He opened it, then looked up at them with a raised eyebrow. They didn’t seem to be in a funny mood, which must have meant they weren’t joking.

“Well, uh… Siblings? Maybe, uh, son and father?” He tried to question, not wanting to believe what was reality.

“No. I know it’s hard to believe, but those two are the same person, just from two different universes. And apparently, they know each other already. It seems like they have a… habit of eating others, or in the case of the smaller one, getting eaten.” The cheetah explained, noticeably still rather perturbed over the entire situation. Meril whistled when he got to the description of the larger one.

“Big guy… Just by ten centimeters, but sheesh, he looks like he could punt me across three walls and not even be winded about it.” He tried to joke to hide the slight nervousness he had about this. But as he looked up, he saw it didn’t work at all – the researchers themselves looked rather worried as well. Before any of them could say something, the door to the room opened and in stepped the two new arrivals: Veltep and Gaiantep.

Veltep, the smaller and more innocent-looking one, closely resembled how an average sheep person of their own would look like, apart from a few jarring differences: Veltep had no nostrils, his wool was cut in a different, unfamiliar manner, and his knees looked wrong – they were knocked, which would clearly hinder him in running. Most of his wool was also cream colored, but his “hair” and mane were darker brown. Alongside those, starting from the middle of the upper arm, and most of his legs were also darker brown in color, with a clear line angling upwards and disappearing on his hips. As he stepped and turned to the side, he could see the line continue to the upper part of his buttocks. He couldn’t have been higher than 160 centimeters…

Movement and the solid clacking of hooves made him glance up at the much larger and more menacing-looking Gaiantep. Meril felt his ears flatten against his head as he regarded the massive Gaian – as Gaian was also the name of his species; it seemed so. Gaiantep seemed to be the complete opposite of Veltep: not only did he have nostrils and healthy knees, but his form was robust, along with a pair of curved horns, ready to ram into anyone who stood in his way. The muscles on his arms and legs bulged noticeably, but his chest and belly were hidden away by the vest he wore. Meril didn’t need to guess that underneath the vest a full eight-pack lay hidden. Gaiantep wore his wool in the same style as Veltep.

The gaian crossed his arms in front of his chest as he leaned back against the wall, flashing a grin at the three of them that turned his menacing look into a rather handsome one. If Sain were to be here, he would have immediately gotten a hard one, and Meril could definitely understand why.

“So, who’s the one wanting to fill my belly for the night~?” His voice was deep and rumbly, yet it had a certain alluring note to it that promised safety and a good time. Veltep, next to him, chuckled, and despite his smaller size, it seemed like he was also ready to jump into action.

That one is sneaky, it seems. I can already see him being a softer dom than his other worldly self. Meril thought while his gaze finally focused on the vest Gaiantep wore. Then, he finally noticed the writing on his vest that read “Service Pred”. They have service preds too? Maybe he isn’t as menacing as I thought. Then, he thought about the possible strength he had in his abdomen, and shivered. _He could still turn anyone into pulp in his stomach. _

Apart from the vest, neither of them wore anything.

Movement brought him out of his musings, as the two scientists moved to their own place – one to sit down at a desk, while the other brought forward a glass of water and the new pill they had to test. The cheetah walked up calmly to Gaiantep, and Meril could still see the nervous flick of the end of his tail.

“Take this, please. The effect is only for stretching, to accommodate people who may be the same size or a bigger size than you, nothing else. We are not at the point of being ready with an anti-acid pill yet, so for now, please refrain from squeezing your prey too much, and you have to let them out before your digestion would truly kick in. I suggest you start with your friend.” Gaiantep took the pill with a nod, quickly swallowing it with the water and handing the glass back.

The cheetah moved back to his place, and Veltep skipped closer to his friend, poking his hard stomach.

“Hope you haven’t gotten rusty, big guy. I won’t make it easy.” Veltep quipped, playfully pushing his tongue out at his Gaian self. Gaiantep laughed, plucking up the venlil from the ground, and hugging him against his body.

“Bold words for someone so edible. But I couldn’t have said it better.” He glanced up at Meril and winked before walking to the middle of the room, looking at the researchers. “So, how long does it take for the-” He couldn’t finish his question, and his throat, chest, and belly visibly sagged and expanded slightly, making all five of them freeze. The two researchers seemed ready to take action, the shorter lizard one already having a syringe in his hand, ready to jab it into Gaiantep to neutralize the effects.

When nothing else happened in the next two minutes, the researchers slowly relaxed with a sigh.

“Sorry about that. Small side-effects like this can happen, but nothing major that we couldn’t fix. Usually…” The cheetah muttered the last part, but Meril knew they all heard it. “If you don’t notice anything else unusual, then please proceed.” For a few seconds, Gaiantep didn’t move, just stood there, before taking a long breath and nodding.

“Well… time to eat then~” He teased, leaning down and licking along the right side of Veltep’s face, holding him steadily as the venlil squirmed and laughed.

“Stop, you big doofus. Just do it already before I present in front of everyone...” Veltep chuckled, shifting even as Gaiantep took a steadier hold of him again and lifting him slightly away from his body.

“Down the hatch you go then,” Gaiantep told him, before his mouth opened wide. Veltep, who was already experienced with getting eaten, flattened his ears against his head and leaned forward. His muzzle pressed into Gaiantep’s jaws that seemed to immediately stretch out, just like how a snake’s would, and his word was plunged into crimson darkness.

Veltep squirmed slightly as he felt Gaiantep’s tongue run along his jaw, a rumble of satisfaction coming from his larger self as he appreciated his taste, before pushing him further in. The mouth around him stretched wider as his shoulders entered his mouth – the flesh squeezing against his form, but not hard enough to make it uncomfortable. His head was soon pushed into the throat, the muscles grabbing at him with a swallow as he was sent deeper. He playfully wiggled as he felt the two strong hands grab his thighs, and he laughed when the fingers squeezed them, before pushing him in deeper.

Outside, Gainatep blew air out through his nostrils as he tried to flex his jaws to get a steadier grip of his wiggly prey, but he couldn’t do so, possibly due to the effect of the pill. Whether it was an intended or unintended side effect, he had no idea. At least he could move everything else as he should.

His jaws stretched out more as he pushed Veltep’s hips into his mouth, his tongue quick in sneaking its way to his crotch, pressing in against the wool that hid his venlil counterpart’s sheath. He didn’t spend much time getting a good taste of him, as the researchers were watching, so he pulled him deeper, moving a hand down to feel his softened throat bulge around Veltep. The sensation felt rather pleasant and less straining than any other time, which was a positive sign for him for the pill. Maybe when they figure out the kinks, he will take a couple back home…

He continued to swallow, his tongue moving constantly to cover Veltep in as much saliva as he could while his knees entered his maw.

From the side, Meril watched with growing curiosity and eagerness as Veltep was steadily disappearing inside Gaiantep, his throat steadily becoming more and more distended. The sight was arousing, and he had to turn aptly away from the researchers to hide the slowly growing bulge on his pants while Veltep’s feet disappeared.

The relatively large bulge moved down along Gaiantep’s body, soon reaching his belly, which began to steadily grow and bloat out, a bit too much in Meril’s opinion as he watched the heavy gut sag.

Gaiantep covered his mouth as he let out a soft burp, resting a hand on his belly as he patted it.

“How was it?” Questioned one of the researchers at the side, with a laptop in front of him, to note down everything he said.

“Interesting. There was no strain, which was nice, but I barely had any strength in my jaw; I could barely grip him to keep him steady. That, along with the sagging front, and my belly being a bit too stretchy, it feels fine.” Gaiantep explained while he poked and prodded his belly, while Veltep inside squirmed with playful giggles.

“Very well, then. If you feel like it, please continue.” The lizard said, and suddenly Meril felt slightly too self-conscious as Gaiantep approached him with a smile.

“Well, it’s certainly a surprise to see a sergal here. But I am eager to see if you taste the same as the others do~” He whispered, leaning down slightly. His warm breath washed over his face, and Meril found himself blushing.
