FAA-112 - Opened a home gym and local housewives are lining up to get serviced

Even if AV is just a product of the production team's fantasies, I think it's a failure the moment the viewer thinks, 'This premise is impossible.' For example, a man casually performing treatments on a woman at a spa, or a pervert having full-on intercourse on a train while no one around notices... This work is exactly the same. It doesn't even make sense as a story.
