She believes she's alone, her voice filling the room as she chats with her friend, her body language open, unaware of the lurking desire. I watch from the shadows, my eyes tracing the curve of her spine, the way her hips sway slightly as she talks. She's a picture of innocence, but I know better. I've felt her writhe beneath me, heard her moan my name. I approach her, my steps silent, my breath shallow. She senses me, her body tensing, her voice faltering. I'm behind her now, my hands on her hips, my cock pressing against her ass. She knows what's coming, and she's ready.
