OBA-234 The landlady who teases us to no end, Mari Aoi

The landlady of our boarding house, Mari obasan, has been running this place single-handedly since her husband passed away. She doesn't have any particular hobbies but works as a fitting model for an underwear mail-order company, and the underwear is incredibly erotic. It's so erotic that we secretly watch when Mari obasan starts trying them on and bet on the color of the underwear. One day, a fellow boarder, Isejima, was cornered and confessed everything. Ahh, what will happen to our fun！！
