Painting Your Skin

A pair of siblings, Jamison and Emilia, had been invited over for a double sleepover at their best friends' house. The parents go out on a date night, leaving Jamison and Victor in charge. It's only later that Emilia and Kirsten barge into the living room, crying that something tried to grab one of them. As proof, there was a large bruise wrapping around Emilia. Looking inside the bedroom, there was a distorted arm, slowly opening the window.
