When I entered a university in Tokyo, I decided to live alone. Living in the countryside surrounded by a large family, I couldn't sleep in a room with nobody. Around midnight, I heard a naughty voice from the neighbor. I wonder if I'm watching it on AV at a loud volume in the middle of the night ... loud enough to think ... No way, I didn't know at this time that the beautiful and elegant wife next door was the main voice of such a vulgar pant voice.
