My mother came to visit the town where my husband and I live for the first time in a while. It's been a year since her father passed away, and I'm relieved that her mother seems to be doing better than I expected. That night, I happened to witness my girlfriend's mother's naked body in the changing room. I wonder how many years it has been since I saw my girlfriend's mother naked...

However, my lustful and erect lower body showed no sign of calming down, so I secretly headed to my girlfriend's mother's bedroom.
