ACOF/Alexander/Vanessa
You go to Vanessa's room in the hopes that she's both awake and wants to hang out. Usually she's still asleep by now, and when she isn't she wants you to leave her alone.
But she keeps forgetting to lock her door, and last time you opened it without knocking she threw a shoe at you. But not before you noticed that she was sitting at her computer with one hand in her panties and her shirt flipped up over her breasts.
So you knock lightly.
No response. Either she's asleep or she has her headphones on.
You turn the knob slowly and push the door open, revealing a third option you hadn't thought of. She's not in her room. Her bedroom is almost as big as Mom and Dad's, but her walk in closet and bathroom take up part of that space at the far end.
