After moving to the city for college, I meet JULIA, a plainly dressed housewife across the hall who often goes shopping on her bicycle. One day she cleans the window with her nipples showing through her clothes. Does she know I am watching? Soon she masturbates and even lets me watch her have sex with her husband. Then I notice her astonishing body and enormous tits. Eventually she displays herself completely naked—and from that day on, whenever JULIA stands nude behind the window, it becomes our secret signal for a creampie affair while her husband is away.
