Setsuna has been remarried to her husband Teruo for two months. She had good sexual compatibility with her unfaithful husband, made out with him almost every day, and enjoyed their night life. However, Teruo is sent overseas for a year and is forced to live alone. Masturbation alone can't handle the pain in your lower body...

It's a one-time play...but I can't get over it. and···.
