Natsuko works at a local credit union. She lives with her husband and two children. Her husband used to run a restaurant, but it closed down due to the COVID-19 pandemic. He currently works odd jobs, but his health is poor and he's often absent. Life is tough, with expenses for her mother, who is battling a long-term illness in the hospital, and her children's education. After much deliberation, she decided to take on a high-paying job involving unprotected sex for the sake of her family. She and her husband have been sexless since she gave birth, and she's been pent up with her mature body and sexual desires for a long time. She tried to pretend that she had come here out of necessity, but she couldn't hide her arousal even before being touched; she was just a secretly lustful wife.
