Whenever I go to Tokyo, I stay at my uncle and aunt's house. Of course, I want to save on lodging, but the real reason is that I want to see my aunt, Aoi. She's a young woman with an incredible figure, too good for my middle-aged uncle. That night, I couldn't sleep, so I went to the kitchen to get some water. But then I saw Aoi masturbating, even though she was supposed to be asleep. I couldn't get the image out of my head, and I just couldn't stay still...
