Miho Tono, a beautiful married woman who knows each other's backgrounds, meets her friend at an erotic massage parlor and engages in an illicit affair involving penetration from behind. (DASS-796)

Feeling down after arguing with my wife, I went to a brothel during the day. There, I unexpectedly ran into Miho, the prettiest mom in my son's class. Although embarrassed, Miho gently said, "This is a secret between the two of us," and then penetrated me. While I felt guilty for having been penetrated once before, the immoral feeling of being penetrated by a mom friend who was even prettier than my wife churned within me. Without realizing it, my feet moved towards the brothel.
