A writhing parasitic worm

Sitting on the desk was a fat, bulbous, purple worm, squirming around now that it was free of its mother. Rose looked at it with a mix of arousal, horror, and satisfaction before she felt the next one pushing its way out of her womb, sending her reeling again. She was surprised it wasn't painful; in fact, it even felt kind of good.

Aiden picked the worm up and looked it over, ignoring it as it struggled to get away. The thing looked like a fleshy slug with no antennae, really looking like a blob of flesh. Aiden mentally probed it and found it possessed a rudimentary intelligence, just enough that he could give it orders if he wanted to. Eager to test it out, Aiden waited a moment and then opened the office door, grabbed a passing woman, and pulled her inside before she could react.

"What the-! The fuck is this?! What is that?!" she screamed, seeing Aiden and Rose naked, with the latter spread-eagled on the desk pushing more worms out of her swollen womb.

"Nothing to worry about. Here, have this," Aiden said, tossing the slug in his hands towards her. It bounced off one of her sizable breasts and fell to the floor, where it coiled for a second before squirming towards the woman with surprising speed. It wound its way halfway up her leg before she could even scream and slipped through her fingers when she tried to grab it. She tried to block its advance, but it was quick enough to evade her panicked attempts. A second later, it disappeared under the short hem of her dress and out of sight. Aiden, able to sense the infectious worm, was acutely aware of what it did next.

Reaching the woman's crotch, the worm secreted some sort of slime, which quickly began dissolving the screaming woman's undershorts and panties. As soon as her vagina was revealed, it wasted no time in pushing forward into it. The woman's eyes widened further when she felt it **** its way into her tunnel, unimpeded by her unwillingness. She froze in horror, unable to do anything as the worm crawled deeper into her most private place. She could feel every inch of it filling her, the thing conforming to her cavern. She felt it stop and hoped it was over, but a second later, she felt it jettison a slimy fluid inside her. Aiden knew it had just ejected its own tainted flesh from its skin, the corruptive goop it was made of seeping into the woman's own body.

The woman could feel the perverse slime filling and changing her. In seconds, her mind went from resistance and repulsion, to wary acceptance, to slightly aroused, and finally to full-blown nymphomania. Her fear of the worm was forgotten as the virus corrupted her, making her yearn for cock, tongue, pussy, tits, or even more of the purple slugs. So long as she could fuck, she didn't care about anything else. A soul-shattering orgasm ripped through her, transforming her body from refined to depraved. Her tits exploded out of her loose blouse, the fabric straining before the buttons gave way and boobs bigger than her head burst out. Her ass became similarly huge, large enough to make a latina pornstar green with envy. She fell to the floor, shaking with continued orgasm.

Satisfied that the parasites would make for effective corrupters and hard from the show, Aiden gathered up the dozen that Rose had given birth to. He swiftly plunged his stiff cock back into her, fucking and groping her big, shaking tits until he shot another massive load into her. Rose once again felt his sperm take root in her, another brood of worms swiftly developing in her eternally fertile body.

"Find someone else to fuck you full of more of my children," Aiden said, shrinking back down to a more normal size. "I'm going to need a lot more of these things by the time all this is over."

"Y-yes my Lord," Rose said breathlessly, her womb stretching again with more slugs. Aiden left the room, carrying the dozen worms with him. Disguising himself would be more trouble than it was worth, so he just used his pheromones to render himself effectively invisible. He walked quickly through the lobby, not wanting to risk the pheromones losing potency in the large room. He ducked back into the staff hallways and made his way to a maintenance room, tearing the door open with ease.

A quick look around revealed what he was looking for, a sizable air vent, more than large enough for his repulsive offspring. Punching a hole in the grate covering the vent, Aiden tossed the armload of slugs inside, mentally commanding them to make their way through the system. He connected telepathically with his new broodmother, who had already managed to find a man to impregnate her repeatedly. Aiden made sure that all new parasites would infiltrate the ventilation system. Aiden could already sense the worm's rudimentary instinct driving them further into the system, seeking out people to infect. Knowing they'd accomplish their goal, Aiden left the maintenance room.
