I'm sad that my sex life is even monitored by the nagging, sadistic wives next door, Mitani and Michino... When I brought my girlfriend over to have sex with her, she complained that my voice was too loud. She ordered me to do it on the sofa because my voice would leak out in the bedroom. To confirm, I had sex with Michino for some reason!! While casually browsing the internet, I found a selfie video of Mitani masturbating!! When I confronted her, she told me that she was frustrated because her husband wouldn't do it for her, and that I should have sex with her!! I felt both happy and sad at the same time...
