A concerned staff member

Only a moment of time to make a choice. Rebecca decided to drop and mimic the other girl she had just infested.

Robert thought he heard someone let out a momentary scream and had rushed to investigate. Opening the door, he couldn't see anything but the back of the couch. What he did notice was mild sounds of the failing women, not that he knew that.

"Hello, are you okay?" Robert called out not knowing who to. Besides the two women the only other person in range was a smiling janitor, who ignored it.

Rebecca was getting annoyed the man was taking his time, and this woman was taking forever to be taken over.

"H-Hello" Robert said with more fear in his voice. He left the door frame and entered.

SLAM

"Fuck" Robert hissed forgetting how every door in this building slams shut.

As he inched in, he saw the blond women whose movement were beginning to soften. He took a deep breath of the wonderful smelling air and rushed forward, then he noticed another woman this one bottomless who he didn't recognize also failing. He really didn't understand why this scene was turning him on, but his boner wasn't lying, he was horny.

Rebecca was watching and waiting for this man to get closer, using the failing to disguise her internal movement of pushing a slug to the edge of her pussy. She was still confused the takeover of a human didn't normally take this long; the host was fighting back more than the others had.

Robert looked around and couldn't find anything that could be the cause of this. He wondered why he was running to seek help and why he wanted to stay. The air was just so enticing here. He began to get closer to where the alluring air was coming from, feeling his hardon squeeze harder and harder against his pants. This mysterious womans sopping wet pussy was bringing attracting his face to it.

Robert never noticed the smirk that grew on Rebeccas face, his eyes fixated on her soaking wet pussy that was creating a rather large puddle under her. Once he got close enough Rebecca used her legs to lift her lower half and wrap her legs around his head. He didn't have a chance to say anything as she rearranged her lower half as he fell to on his chest, his hard cock hurting as it hit the floor. She pushed his head deeper into her pussy as she soon felt a slug emerge and slip into Robert's mouth.

Robert was freaked out at first but then found himself in love with the flavor of this woman's pussy. He didn't exactly accept creature that entered his mouth, but he certainly didn't reject it.

Rebecca relaxed her legs as she felt the man between them begin flailing. She looked at the blond woman who was still trashing around on the floor, not as much as she was but it was still taking too long. Something is wrong with this soon to be host, but perhaps this will lead to another opportunity, much earlier than the slug had wanted.
