I'm going to make you a man!

Overview

My husband and my son have three members. I have a problem with Sayaka, but it's dissatisfied. One day when my husband refused to have a relationship because he was tired, my son's friend was in the bathroom. I accidentally witnessed my erection in the park. I got excited when my son and son's friend Yuki sneaked in to get a raunchy video. I run an errand to my son, and Yuki and I are left alone..
