A divorced and single son. One day, when I grew up and got a job, I planned a hot spring trip without my parents and my child used my son's vacation. At some point, her son's feelings were distorted by his young and beautiful mother. A son who couldn't stand it and approached his mother. Amidst the flickering pleasure, perhaps I myself had really wished for something like this. Hibiki herself also sought pleasure in sex... A mother and child looking for each other in Joshujuku... Free trial points for the first time!
