Nothing, it detects the infected

You prepare yourself to flee if the scan outs you as a demon. It finishes with no warnings or alarms.

"What was that?" You ask.

"New technology. It can actually detect free Lilith Strain viral particles. Every door below has one. If someone gets infected the whole place locks down."

Internally you seethe. The foolish mortals should be finding a better way to infect themselves, not resisting. None of your anger reaches your face. "Cool!"

Alice inserts a key and turns it backward. A small door slides open. She puts her thumb down on a panel and puts her eye up to an apparatus that looks like the end of a telescope. In a moment another panel opens revealing a dozen numbered buttons. Alice pushes twelve, and the elevator begins to descend.

You go down several floors before the one lights up. By the time you reach twelve you must be several hundred feet underground.

The elevator stops and everyone gets out. You follow Alice.

Alice walks a bit the turns. "Welcome to our research facility. We call it The Cave. There is a locker room over there." She points to a door. "When you're changed come see me. My office is two doors down to the right."

You slip into the locker room. You let the illusion of a torn white dress dissolve, and admire your naked form in the mirror. Even without your demonic form, you are spectacular. Your hair is a perfect wavy auburn. Your breasts are massive, round, perky, and sit high on your chest. Your waist is thin giving you a waspish figure. You turn displaying a round flawless ass. Your pussy is hungry and dripping. You may not be able to take advantage of the Lilith Strain here, but as a demoness that's hardly your only trick.

There is a substantial collection of clothes as well as lab coats in one corner. You look through the clothes hoping for a latex minidress. Sadly, your hopes are dashed. You settle for a tube top, and a pair of very short shorts. You slide a white lab coat over it.

You fix your 'makeup'. When you are done you could be a lab tech by day, prostitute by night. The look is perfect.

You wander into Alice's office. She looks up. "You look great Eve. I've got a few things for you to do. You need to see Joe at some point to get security clearance. Caroline our lead researcher could probably use some food or coffee. She forgets to eat sometimes. We also need to get You some sleeping quarters. Larry on level one can help."

You mull over what to do.
