Atsuko has been married for five years and lives an ordinary life. They don't have any children, but they lead a modest life together with their husband. There is something that Atsuko has been keeping secret from her husband all this time. That is, the fact that she has been having a sex friend since before they got married. Their physical compatibility is so good that they can't break up, and the relationship has dragged on. Her instincts as a woman are awakened by the big cock that is different from her husband's. A deep throated big cock blowjob. A raw creampie that makes her beg to get pregnant. A daytime wife drowning in pleasure.
