Nakaide no Kininsojo, his mother and children's passion, Nanako Uchida

In a few more years, my husband and son will retire from retirement. During my husband's long solitary assignment, I had a relationship with my son. Even now ... it is a secret to my husband. My husband and I are old enough to have sex for the first time in a long time. My son said, "I'm glad you did," but somehow it seems to be lonely. Even after the retirement of my husband, I would like to live together with a married couple, but physical relations with my son are unlikely to break.
