Deep inside, the serum was changing the two men. Mutating their organs to create a sort of womb. To the men, it felt like deep and intense cramps. Tobias was reduced to a whimpering mess, curled up into a tight ball with both hands between his legs. Cupping his swollen cock, feeling it twitch and grow.

The figures watched outside, waiting for the process to finish. Some debated letting the humans breed each other while others argued for being first to breed them.

Dan was curled up in a foetal position as his stomach and pelvis shifted, causing him to groan loudly. His cock was once again hard and throbbing, and he hrld it in his hands, massaging it tenderly

[Hyenadog]

Tobias whimpered pathetically, still curled up on the bed. But the aches and pains started to fade, leaving him with a new ache, intense arousal. He made an alarmed sound as he grew hard, looking down at his mutated appendage. It throbbed and twitched in his hands, and he couldn't stop touching it.

"Wh-what's happening to us?" He whimpered, giving a strangled moan as he started jerking off.

[Mpregbelliespls]

“I... I don’t... know” dan whispered between pained moans

His cock was throbbing with every stroke, his arousal growingstronger. He turned to watch tobias anc his erection grew even more

[Hyenadog]

Tobias moved closer to Dan, biting his lip. He couldn't control himself, pushing him onto his front and mounting him. "I....I can't stop." He panted as he lined himself up and thrust in with a loud moan.

[Mpregbelliespls]

Dan yelped as he felt tobias enter him again. He couldn’t do anything but moan as he was pounded, his cock beginning to throb even more

[Hyenadog]

Tobias rutted into Dan hard and fast, gripping his hips tight and pressing his forehead to the man's back. He cursed and moaned, quickly reaching his peak. His cock throbbed and twitched before unleashing a flood of cum into the other. Tobias could only tremble as he rode the waves of his orgasm, collapsing against Dan when it was over. But a fire still burned inside. He needed to be bred as well.

[Mpregbelliespls]

Dan moaned as he felt his ass fill with warm cum. He could feel tobias quivering against him, and started caressing him. As soon as tobias was done, Dan flipped him onto his front and was fucking him harder than before, grunting every so often

[Hyenadog]

Tobias yelped when he was flipped, moaning as Dan pushed into him. He cried out, becoming quite vocal as he was pounded into the bed. Soon he was trembling, reaching back to grab at Dan and pushing back into his thrusts.

Within Dan's body, Tobias' seed had taken root. Already beginning to grow so quickly.

[Mpregbelliespls]

Dan sped up as he felt an orgasm building up, quickly thrusting into tobais once more. He let out load after load into his ass before it began to taper off. He moan as he pulled out, his cock still slightly hard.

The same thing inside dan was now taking place inside tobias

[Hyenadog]

Tobias gave a long shaky moan as he was filled, blowing his own load all over the bed beneath himself. He groaned when Dan withdrew, rolling onto his side to catch his breath.

It wasn't long before the growth within made itself known. First in Dan, then a few moments later in Tobias. A weight and pressure growing in their lower abdomens. A bump taking shape, startling Tobias, who rolled onto his back and put his hands over it. "Oh, shit...wh-what's happening?!"

[Mpregbelliespls]

Dan felt his abdomen slowly expand, pushing out very slightly. HE looked over at tobias and saw the same thing happening to him.

“I... I don’t know!” He cried out, not sure of what to do.

He ould feel his skin stretching out and pushing his organs around slightly

[Hyenadog]

Tobias watched in horror as his belly grew, gaining a distinct firm rounded shape that could only be one thing. "Oh, god!" He yelped, looking over at Dan with wide eyes. "We're pregnant!" He added, sitting up quickly.

Something slid out of the wall nearby, a low orifice with a seat...probably a toilet. Nearby, another fixture slid out, like a water fountain. And a strange straw slid out, probably some form of nutritional substance dispenser. The creatures watched, wanting to see how well the subjects handled birthing their own kind before moving forward.

[Mpregbelliespls]

Dan stared as his belly button rounded out, looking like a six month belly, with a very big baby. He pushed and poked it with his hands, trying to stop its growth, to no avail.

“We can’t be!” He said, thinking it all a bad dream

[Hyenadog]

Tobias whimpered, slowly standing up. His belly jutting from his slim frame, still growing and shifting. "Th-there's something inside. Nnh, it's moving." He gasped, putting his hands on the tight dome, feeling something squirming within. "Oooh, god...how's it getting out?" He gasped, looking over at Dan with wide eyes.

His cock hung between his legs, the underside swollen and tip enlarged, preparing for what was next.

[Mpregbelliespls]

Dan heaved himself up, his belly now nearing the full term mark. He felt movement inside him, squirming and kicking around. “What is it!” He said, confused. Hecould feel his cock swelling again, but something was different this time. It felt thicker and looser.
“I don’t know. I really don’t know”

[Hyenadog]

Tobias looked down at his swelling belly, seeing the thing within moving around. "F-fuck....i...I think we knocked each other up." He said, looking worried. "I'm sorry." He whimpered, looking away.

He was quickly reaching full term, wincing at early practice contractions. He started pacing the room, his belly shifting and dropping lower. He gasped, cradling his belly.

[Mpregbelliespls]

“I...it wasn’t your fault” Dan said.”im sorry too”

Dan watched as his belly pushed out to look like he was just past due. He was enourmous, and he could feel lots of movement underneath the skin. He felt as his belly dropped and the baby shifted ready to be birthed. “How are we gonna push these out?”

[Hyenadog]

Tobias wobbled to the bed, bracing one hand on it as the cramping got worse. "I...I don't know." He muttered, wincing as the pain got worse. "F-fuck. Oh, god." He gasped, feeling his body clench harder, pressure building deep in his pelvis.

Suddenly, something inside popped, making Tobias yelp as fluid gushed from his swollen manhood. "Oh, oh god. Oh god! N-not there!" He cried, cradling his low-slung belly as horrible realization hit him.

[Mpregbelliespls]

Dan watched as tobias started panicking and moaning in pain, knowing what was coming next. He felt his belly tightening and then fet a popping feeling, seeing the same liquid gush out of hia own cock. He whimpered as he felt movement inside himself
