Only her

You are both astonished for a few seconds, then her expression of pure last gives way to horror and embarrassment.

-Kim! N-No! Get out, get out!-.

Scared as fuck, you slam the door closed and withdraw some steps. What the hell did just happen? You thought that Kim was going to possess her but, clearly, it was not the case.

"Wait wait wait, what she said before... she was fantasizing about her? Oh my God, Tina likes her too??".

-Girls, be quiet please!- Comes the tired voice of your mom from inside her room. Your parents! If Kim, or whatever that goo is, has not gone inside her sister, maybe they are its target!

"Shit shit shit!" You rush to them, looking for any trace of its passage, in vain. All you can do is try to open the door and peek inside. You gulp and proceed.

The room is completely dark, but you can distinguish your parents' forms sleeping on the bed. Your mother grumbles for a second, but then becomes calm again. Still no sign of the intruder. You flinch and close the door.

You just don't understand. Where has she gone?
