A childhood friend who grew up in a rural area with a four-year age difference. They went to different universities and became estranged for a while, but reunited after becoming a member of society. Even after marriage, both of them were lighthearted about sex because of the extension of their friends, but one day in the 25th year of marriage, her husband suddenly told her wife that she had a desire to be cuckold. "It Wasn't Nearly Twenty Years, But I Wanted To Be With You Again... If You Say That, I Can't Say No..." I made up my mind.
