Water ran down your body from the showerhead as you rinsed your hair of shampoo, eyes closed. You were, for once, in a calm, relaxed state as the water hit your face. After a moment, you heard a sound from the other side of the shower curtain, almost like a zipper being undone, but you thought nothing of it. A few more moments passed and not another sound was heard, so you just shook off the feeling of being watched. Suddenly, you felt a pair of hands on your sides from behind.
