A Mysterious Girl Keeps Sending You Nudes

It's been a long, stressful day at school, but you are home. Your mom hugs you in the kitchen and gives you a snack. Your dad stops you, reminding you that the lawn needs to be mowed soon. Your sister storms past you, slamming the door to her room, which has a big sign that reads STAY OUT taped to it. Finally, you enter your room to relax.

After an hour, a notification pops up on your phone. It appears to be some sort of text message image:

"what do u think, CraveU user??? ;)"

The message contains a picture of a stunning naked girl who appears to be around your age. The girl is using a single finger to cover up both her nipples and pussy at the same time, a camera trick that became an internet fad a few years ago.

Upon further inspection, this appears to be not just a picture, but a video. The video does not provide further context. It just shows her making the pose, with the light sound of her breath playing in the background. Her unsteady finger waves back and forth, almost revealing her nipples and pussy to the camera. It's a video of enchanting lewdness.

The girl seems incredibly familiar, but since her face is covered, it's hard to say who it is. Is she a neighbor? A classmate? A bot? Who could this be? And what is the right way to respond to something like this.
