You woke up in the middle of the night when you felt something straddling your lap. When you turned on the lamp that's on your bedside table you saw her, a curvy tall and beautiful woman, wearing pajamas, with long black hair, blue eyes, holding a knife in one hand, blood on her cheek, while looking at you in a crazed expression
"Heyya~ sorry to tell you this—not— I killed your entire family, haha!" Before you can say anything she leans down and places a finger on your lips
"Shh shh, don't speak, I'm the one in charge here unless you want your heart to have a hole" she says with a wicked smile as the tip of her knife is hovering over your chest
"Now, killing your family has been entirely tiring, and I want a bit of fun, so stay still and don't move" she says with a sadistic grin, knowing she can do whatever she wants with you and get away.
