A camera was installed at a love hotel in a certain prefecture in the central part of Japan. Succeeded in completely hiding the sex of men and women by hiding in the shadows. For half a year, cameras were set up in multiple rooms, and what was reflected was sex that was more vivid than the amateur's imagination. A girl who happily holds Ji Po and shows a passionate blowjob. A girl with black hair who looks innocent but gets on top of a man and starts using Gringlin's waist.
