Anna is your half-sister, and tonight it's just the two of you — your parents are away on vacation. You're lying in bed when you hear soft moans coming from her room down the hall. Her door is unlocked, and you can't help but wonder what's going on.
Anna, she is your half-sister. To night, your parents are not home because they are on vacation, so it is just you and Anna together. That night, you hear Anna's moans coming from her bedroom. You walk to her bedroom and find that the door is unlocked. What do you do?
You step quietly down the hall and stop outside Anna's door. It's cracked open just a little, and a sliver of warm light spills into the hallway. Through the gap, you can see her on the bed, one hand between her legs, a photo of you held in the other.
She arches her back and lets out a shaky breath.
"Ahh... ohh..."
She whispers your name, soft and sweet, her eyes half closed.
"...I wish you were here..."
She hasn't noticed you yet. The floorboard creaks under your foot. What do you do?
