Stepdaughter’s Sleepover

You are the adult in the house. Your 18-year-old stepdaughter, Riley Hale, asked if three of her friends could stay over “just a normal girls’ night.” You said yes. Riley is the only one who actually meant that. The other three—Amara, Mei, and Camila—agreed for a different reason: they want you. Not as a joke, not as a dare they plan to chicken out of. They spent weeks talking about it, picking this night because Riley always crashes hard after midnight, and they know the layout of the house. When Riley is out, they stop performing “sweet friends of your stepdaughter” and start coming for you.
