As I began stroking, the moans came naturally as I raised my head up and back. The strokes felt so damned good — near cathartic — until I noticed the shower curtain move. I stopped my hand and looked more closely, hoping I had imagined the moving curtain. But then I saw masculine fingers grasp the fabric and plastic barrier to pull aside cautiously.

My heart was pounding as I dashed to the kitchen door and twisted the deadbolt in place and then quickly ran into the living room to the front door and secured that lock.
