Yes, and no one notices until its too late

Ethan, still at the window, watched as the many worms disappeared from view, their fat little bodies too close to the building to see, despite his best efforts.

"Where'd they go?" Ryan asked, looking out the window as well.

"Don't know, they crawled towards the store, but I can't see them anymore," the young punk man said, moving to rest against the wall. It looked like most of the monsters had moved on, but it was still far from safe. He guessed they'd have to wait a few more hours before it was remotely safe to leave.

"Wha-what are we going to do?" Catherine asked, slightly less hysterical now, but still on the verge of panic.

"We're going to stay here and wait for all of those things move on," her husband Nathan said gently. "Once it's safe, we'll get out of the city. I'm sure the government is already setting up a containment zone. We'll be okay."

"What if we're n-not?" Carly asked from behind the counter, hidden out of sight. The significant tremble in her voice made it clear that she was crying. No one pointed it out. "What if those things realize we're in here?"

"Is there a back door?" Nathan asked, already stepping up as a leader in the perilous situation.

"Y-yes, but it's locked. The manager doesn't want us going out there to smoke or whatever she thinks we do. She's a bitch," Carly said with a small laugh bordering on hysterical.

"I think that's a requirement for being a retail manager. You've got to be the toughest person in the place," Ethan said quickly, a habit he had when he got nervous. "I worked at a place once a while back where my boss Tim, huge guy, must've been 6'2, 230 pounds, once got into a staredown with this absolute nut who-"

"For fuck's sake, shut up," Ryan said, pressing his hands to his temples. "If I'm going to be stuck in here with you and you keep going on like that, I will open that door and throw you out it." Ethan opened his mouth to argue, but a **** sound from behind the counter stopped him.

"Uh, Carly? You good there?" Ryan asked, moving away from the window and towards the desk. No reply came. The businessman stepped closer and rounded the corner of the counter, horrified by what he saw.

Carly was slumped against the back of the counter, her arms and legs twitching slightly as one of the fat, pale worms pushed into her small mouth. Her hazel eyes were rolled back, barely visible beneath her fluttering eyelids. Another **** sound came from her as the vile creature **** its way deeper into her body, its tail slipping past her lips but still visible in her open mouth. Carly gagged slightly and a visible bulge stretched her throat, slowly moving down her neck. At the same time, her twitches became spasms, her entire body convulsing on the floor.

"Fuck, they got in! Where did they come from?!" Ryan shouted suddenly, abruptly realizing that they were all in danger. He looked around, but couldn't see any other sign of the worms or even where the one in Carly's throat came from.

"What do you mean? Those slugs?! How?" Ethan yelled, also looking around in a panic. Catherine screamed again, clutching her husband close, who was looking around slowly and deliberately. "I don't see any, are you su-OH SHIT!" Ethan shouted as he felt something smack against his leg. By the time his hands had shot to it, it had wriggled along thigh and through a tear in his jeans. He felt the slimy thing squirm along his ass, dread filling him.

"Nononono, it's going for my AAUUGGGHHH!" he cried, the fat worm pushing mercilessly into his asshole. "GAH SHIT, IT HURTS! IT...UUUUGGNnnnn..." he groaned, falling to his knees to cope with suddenly being filled by the disgusting invader.

"Shit, where are they coming from?!" Ryan exclaimed, spinning in place to try and see anywhere the creatures were coming from. He saw nothing, no indication of where the next worm would appear. "You two need to ge-OOF!" His shout cut off by Carly suddenly throwing herself at him and clinging to his shoulders.

At least, she had been Carly. Now she wouldn't have looked out of place on the cover of a porn mag. Huge tits bounced freely through her torn shirt, the torn fabric pulled apart by the bulging flesh and strong hands. Her ass, formerly something barely fit for sitting on, now bounced and jiggled with every movement, the large globes enticing everyone who saw them to imagine their firmness. Her face, once acne-scarred and plain, was exquisitely formed, flawless, and beautiful, eyes changed from hazel to a paleness reminiscent of milk.

"Ugh, fuck, get off me!" Ryan yelled, trying to push the clingy harlot off. She was having none of it though and easily clung to the larger man. With a quick twist, she brought them both to the ground, her voluptuous body pinning the businessman as he struggled, her tongue slipping out of her open mouth. Ryan couldn't see, but the red muscle had been replaced by the fat body of the worm that had penetrated her mouth, grown to a monstrous size that would make breathing difficult, much less speaking. The tongue twitched erratically, as if still alive, before shooting forward to burrow into the man's head, easily pushing through scalp and skull to reach his brain.

Carly's throat bulged again, though this time the thing in her throat was moving up instead of down. The bulge filled the vile tongue and a moment later, a mouth opened in its tip, releasing a flood of slimy liquid and small, maggot-like creatures over Ryan's grey matter. The small creatures immediately went to work, burrowing into the man's brain, joining the virus in taking control of him, his body seizing as his thoughts were literally consumed.

Nearby, Ethan's cries had tapered off into quiet whimpers and grunts. The worm had taken firm root inside him, its virus-filled body merging with his prostate. The mutated organ immediately went to work, saturating his body with the virus. His bones creaked as they grew slightly, giving him a taller stature and wider build until he was thick with muscles. His titanic legs and frame tore his already ripped clothes to tatters. His pants fell apart, revealing a monster of a cock, much larger than the one he had minutes before. Its tip was enormous, nearly larger than the shaft it was attached to.

Ethan groaned loudly as pressure started to build behind his dick, begging to be released. He immediately wrapped his larger hands around his even larger cock and pumping it furiously. His groans of pleasure joined the shuddering gasps of Ryan and Carly's satisfied gurgling, the fully infested girl cumming with each burst of maggot creatures she pumped into the businessman's brain.

Through it all, Catherine and Nathan watched, frozen with fear, as their fellow survivors became their new tormentors, trapped inside the shop with them. Their only escape was barricaded by their own hands and blocked by three newly Infected. Catherine whimpered and clung tighter to her husband, rightly afraid that they would not be able to get away.
