The concept is 'working married women,' so most of it is styled as 'secretly filming erotic acts with a housewife while she's at work.' Because of the fixed angles and lighting, it's sometimes hard to see the actress's expressions, so if you like that kind of raw, unpolished feel, you might enjoy it. Overall, there's a higher ratio of 'mature older women' than 'pretty young wives,' and there are many chapters featuring only oral sex. There are no original titles or actress names listed either. Personally, I didn't know most of the actresses, so it felt like watching amateur mature content, but the chapter with Yuri Nikaido (the actress who appears around the 30-second mark of the sample) was good, so I'm giving it two stars.
