SPRD-975 Mom, you're way better than that bitch wife... Miyamoto Saori

A few years after my stepfather passed away, I hadn't been to my wife's hometown. However, this time I returned for her high school reunion. While taking a bath, I realized there was no body soap and asked my wife to bring some from outside the bathroom. As I waited, the door opened, and it was my stepmother! She smiled and refilled it, even washing my back. Though hesitant, I couldn't refuse her insistence. When she said she would wash my front too, I embarrassingly got an erection but she said, 'As a daughter, you haven't done this, right? If you're okay with it, let me do it.' And I stupidly agreed.
