Friend's Mother ~Final Chapter~ Rikako Oikawa

Unable to suppress her sexual desire, which increases as she gets older, Rikako spends her days masturbating every night. Her son's friend Nobuaki senses Rikako's frustration. When I came to stay at her house, she secretly peeked into Rikako's daily routine. That night, Nobuaki, who had a faint smile on his face, spoke to Rikako in her ear. I took a picture of my aunt masturbating, right? Do you want me to delete it? Then what should I do? You know what to do, right?
