Demonic Attack.

Dr. Simms watched as soldiers started to run towards the commotion as five figures came into view. Her blood ran cold when she realized that they were more of the super Demons, three Succubi and two Incubi who were forcing their way into view, grabbing anyone near them and forcing them to the ground and taking them. Five demons would soon double to 10... and then more...

"Fuck..." Dr. Simms said, recognizing two of the Succubi as the women who had brought the new Succubi in. "Secure the lab! Sound the alarm!"

An alarm started going off as the outer doors shut, they had to contain this before it was too late.

"Its already too late, slut to be," the hiss of a demon's voice said and she turned to see the Jade Succubus standing there, her massive tits pressed against the glass. "You will soon become part of the biggest Demon Army on Earth..."

Dr. Simms shivered a bit, she felt a small bit of arousal at the thought, but she had to fight it. These demons were not going to win. They would contain this and everything would be back to normal.

She looked in time to see the soldiers raise their guns and aim for the demons and their prey who were already taking on demonic traits. The disease was accelerating, the strain was working to take humans faster now. There was a sound of gunfire as the soldiers riddled them with their blessed bullets and the demons fell to the ground.

"Your little uprising is over," Dr. Michaels said. "Accept your fate, Demons."

All the Succubus did was laugh. The scientists and the demons squared off against one another, all three Succubi now rubbing their bodies against the glass. They were horny, but they were contained.

That was when the screaming started.

Dr. Simms turned around again in time to see that the soldiers and scientists who had gone to check the bodies had been grabbed and **** to the ground, quickly disarmed as their armor and coats were shredded. A Succubus that used to be a nun that had been brought to bless weapons **** her pussy down on one of the soldier's cocks, letting out a scream of pleasure as his cock filled her.

"We are more than demons..." The succubus hissed as the two scientists watched in horror, the screams turning from fear into pleasure. "We are the Lilith Strain, concentrated in power. Your holy weapons won't stop us, we will take this base, then the arena above... and then all of humanity."

And then she raised her fist, and punched the glass and it shattered.
