Most of the problems that housewives seek advice on are about their married life at night!! By frankly talking and sharing their sexual worries, strange feelings begin to grow and they end up having sex in this documentary!! Nanako, whose husband doesn't even foreplay her and only has self-indulgent sex, Ren, whose husband won't conceive due to a sexless marriage, Rino, whose husband's sex doesn't feel good at all, and Rena, whose husband doesn't do anything at all and her sexual desire is building up, which is causing her stress. She goes to her friend's husband for advice because "it's hard to talk to men about it," and ends up having sex with him as he gives her a lecture and demonstration!!
