Just like in an erotic manga, you can hear the inner voices (their true, sexy thoughts) of young wives! Unlike when they were younger, the number of times they have sex has drastically decreased recently, and these young wives are secretly frustrated... On the outside, they don't think about anything erotic! They coolly carry out their work and housework as if to say that. But in reality, their true thoughts are swirling inside: they just can't get enough of sex! What if you could hear those super-naughty inner voices that they don't want anyone to know about...? You'd want to know what they're really thinking, right? This work features four greedy wives (a housekeeper, a female boss, a mother-in-law, and an aunt) whose inner thoughts are leaking out! Who would have thought women were thinking so many naughty things in their hearts? Enjoy the super-naughty inner voices of these women!
